Analysis of The Movie “Patch Adams” Essay

The film opens. Patch has checked into a mental institution. His condition was depression. The environment looks like a jail cell, dark and depressing. During his stay, he realizes that the doctors did not help him in his recovery. Patch Adams’ psychologist was indifferent to the patients in general. The psychologist did not show any interest in his patient. Pach Adams’ psychologist seems to not have any interest in listening to Patch Adams’ feelings. In many cases, he is more interested in his cup of coffee. Patch Adams realizes that he is not being heard and lose the trust of his psychologist. He makes great friends at the mental institution; regardless of his condition, Patch Adams was able to help some of the patients at the mental institution. He started by showing interest in their problems and helping them to overcome their fears. Without studies, Patch Adams showed more skillfulness in listening and having a humanistic tool than the medical staff. Later, Patch Adams decided to become a doctor, which gave him a purpose in life. Patch Adams was very wise and happy man. Helping others made him cure his depression. As a medical student, he uses humor and happiness as medicine with the patients. Most of the students and professors did not like him at all. It was like when Bernie Sanders tried to convince Republicans and Democrats that they supposed to be working for the working people not only for the one percent. In addition, Patch Adams observed a lot of problems in the hospital. Nurses were not treated the same as doctors. Children who suffered from cancer passed in their rooms without joy and hope. Relatives of patients who had to fill out tedious forms instead of being with relatives in life or death situations. He had a revolutionary idea after seeing these problems. He wanted to have a system where patients were not seen as a business because doctors should act more human when they treat their patients. He wanted to help them to b e healed not only of their illnesses but also of their social problems. After many difficulties, he graduated as a doctor. INTRODUCTION Communication in a Healthcare setting is one of the most important tools. Communication skills are something that many individuals have to work on. Not everyone knows how to communicate effectively, especially when dealing with a variety of cultures. Physicians must master their skill communication to improve the patient’s experience. Communication is both verbal and physical. Communication has been shown to favorably affect clinical outcomes, patient adherence, patient satisfaction, and reduced malpractice risk. The movie is based on Dr. Adams’ real life. Dr. Adams’ fundamental idea is to make us understand that medical attention is not only about focusing on the problem or disease. The medical attention is also listening to the patients. Providers should help their patients in an integrated manner. Patients should be approach physically and emotionally as well. The film has many aspects of health communication. Some of them are therapeutic communication (patien t-center), communication empathy. active listening (empathy), and trust. The communication between Patch Adams and his patients is very deep. Patch Adams does not focus only on their pains or symptoms. Rather, he asks them about their lives, family, work, friends interests, etc. Therapeutic communication (Patient Center communication) is very important. It is not just about touch-feeling and more humanistic. Interrupting a patient prematurely closed-ended questions. When doctors do that they fail to address the patient’s concern’s and fail to really understand the patient’s full agenda for why they are seeking healthcare. Additionally, when doctors ignore personal information, patients get the idea that they are not being heard and that the doctor did not care about them. As a result, patients will not take their medication or follow the procedure that the doctor recommended. For instance, Patch Adams’ relationship with his psychologist was untrusty, resulting in the abandonment of treatment and distrusting the system of the do ctor and provider as well. This causes a lot of problem in our healthcare. On the other hand, when doctors use open-ended questions, it can be utilized to allow patients to freely talk about their own problems or feelings associated with the complication.† Open-ended general inquiries claim a lack of knowledge of patient’s problems, encourage their de-novo presentation, and frame patients (at least initially) as being active authorities over their own health information.† (Robinson, Heritage, 2005). Active Listening is different from just hearing and repeating what was heard. This skill can help us reveal not only what the patient is saying but what the patient is thinking and feeling (Servellen, pg. 91). Patch psychologist showed lack of this skill. When Patch was telling his childhood story about his dad death †Dad told Patch Adams at the Korean world hid dad lost his sold, all the time Patch Adams thought he was the one who lost his sold† The disconnection between psychologist and patient showed lack of empathy, focus, and attention. Patch Adams at the Medical School was able to display active listening to friends, patients, and classmates. Active listening requires providers not only to hear, but to listen; not only to see but to perceive; and not only to touch but to feel (Servellen, pg.92). Trust, I personally think that trust is the most important quality to get from patients. It is probably one of the most difficult quality to achieve and keep in these days. †Patients’ trust in providers usually evolves over time. Patients most of the time will self-disclosure until they observe that providers are acting on their behalf.† (Servellen, pg. 109). Building trust is very crucial for a good relationship and for the outcomes of the patients. For example, a patient who does not trust or like the practitioner will not disclose complete information efficiently. Patients who are anxious will not understand the instructions clearly (Dorr & Lipkin, pg. 4). Conclusion: The main reason for communication in the healthcare setting is not just to ask and collect information. Should be beyond, not only focusing on the problem of the patient, communication help us as well to establish trust and good relationship with patients. If we are able to gain the trust of our patients we can guarantee a good relationship and better outcomes for patients. If we gain trust Healthcare professionals will not feel fear to be transparent as a result our communication with patients will be fructose. Making patient participate in their care, in quality of life and have higher satisfaction.

Canon strategic analysis case study Essay

This report examines the competitive strategy that enabled the â€Å"camera company from Japan†1 not only to break down the monopoly enjoyed by Xerox in the copier business in the 1970s but also to grow into a highly diversified, multi-product and multinational premier company. Specifically, the report considers (1) the competitive strategy of Canon (2) the major resources and capabilities of Canon (3) management of the development and transfer of capabilities throughout the organisation (4) Canon’s strategic perspective (5) is Canon successful? (6) conclusion and key learning points Competitive strategy The dominant generic competitive strategy adopted by Canon is differentiation. The company deployed its technological capabilities and know-how in fine optics, precision mechanics, microelectronics and fine chemicals to develop innovative and state-of-the-art products, which were of better quality than those of its competitors. These products resulted mainly from the strong, decentralised research facilities of the company and the incredible ability of its engineers to convert research findings to new products and technological innovation. Although Canon succeeded in manufacturing products at low cost, it did not deliberately compete on the basis of low price. The quality of its products combined with significant amount of marketing and deliberate brand development efforts have established a sound reputation for Canon in the market and these underlie the competitive advantage of Canon. Resources and capabilities The major resources of Canon are as follows: (1) Financial capacity: product innovation and attendant growth in sales and profits enabled provided Canon with the finance required for additional research and product development which resulted in further increases in revenue in a virtuous cycle. (ii) Decentralised R&D and new product development: in addition to the company’s main research centre which supports state-of-the-art research in optics, electronics, new materials and information technology, each product division has development centres (manned by its own R&D personnel) where 80% to 90% of the company’s patentable inventions are discovered. Three corporate research centres are responsible for applying the research findings to new products development. The company also introduced programmes to reduce the time for taking new technology to market by 50%. Innovative products provide the company with competitive advantage through new sales and patents, which serve as entry barriers to competitors. (iii) Marketing expertise: the strength of Canon’s marketing expertise derived from an effective product introduction strategy, a strong dealer network, large advertising spend and brand development. New products are first introduced in the home market before they are sold overseas in order to enable the learning and experience from the home market to be transferred to international markets. Even then, new products are only introduced into the market through proven, existing channels, to minimise the risk of failure. The Company also built up a strong dealer network which supported both sales and service of copiers. Dealers had to complete a service training course before they are allowed to sell copiers. Canon regards dealers as a vital asset through which it is able to understand and respond to customers’ needs on a timely basis. Brand development efforts are undertaken through advertising, corporate sponsorship and a deliberate effort to only associate unique and qua lity products with the brand. This was demonstrated when Canon decided not to market the inferior CPC technology licensed from RCA under the Canon name. (iv) Partnerships and joint venture relationships: despite Canons strong technological capability, it acknowledges that it has neither the resources nor the time to develop all the technologies needed for its products. This resulted in the development of strategic alliances and joint ventures in  Europe and in the US, with companies such as CPF Deutsch, Eastman Kodak and Texas Instruments. These relationships were not only sources of required technology, they also served as strategic tool for market development for the company’s products and for mitigating foreign trade tensions. (v) High quality, low cost manufacturing: Canon has a philosophy of producing quality products at the lowest cost. Strong emphasis is placed on inventory management, waste reduction, material and production planning. Continuous improvement in productivity was achieved through automation and innovative process improvement. The commonality of parts between adjacent copier models also contributed to low cost of manufacturing due to standardisation. High quality, low cost manufacturing combined with premium prices provide Canon with an opportunity to earn good margins. (vi) Highly motivated work-force: employees are held in high regard at Canon. This was applicable to both business unit managers as well as production line workers. The business unit managers were empowered to act as surrogate CEO of their units and to make quick business decisions. A number of initiatives were implemented to motivate production workers. These include the â€Å"stop and fix it† programme (which empowers any employee to stop the production line if he or she believes there is a quality problem), responsibility for maintenance of own machine and on-line feedback on quality and production targets. The level of motivation was reflected in the suggestion programme implemented by the company which resulted in more than 70 suggestions per employee per year, with a 90% implementation rate of suggestions offered. These resulted in significant corporate savings relative to the cost of the programme. (vii) Visionary leadership: the company’s president, Mr. Kaku, was a very effective and visionary leader. He introduced the diversification drive, corporate entrepreneurship and was very focused on the long term direction of the company. (viii) Suppliers relationship: the long-term relationship developed with suppliers enabled the company to outsource the manufacturing of over 80% of copier parts to suppliers. (ix) Long-term approach: Canon always takes a long term view when making management or strategic decisions. This was demonstrated for instance when the company developed the bubble jet printers which was capable of cannibalising its well established laser jet printer. This approach enabled a consistent and focused implementation of strategic choices rather than short term panic reaction to crisis and challenges. These resources and capabilities are extremely important for Canon’s competitive advantage over its competitors. Management of development and transfer of capabilities throughout the organisation As Canon grew into a multi-product, multinational corporation, the company’s management took the following steps to ensure the continued development and transfer of capabilities throughout the organisation: (i) Implementation of independent entrepreneurial business units: independent operating units were created for cameras, office equipment and optical instruments. The business units were empowered to act on their own but were given clear profitability targets and highly ambitious growth objectives. (ii) Functional committees: three functional committees were established by management to oversee the company-wide administration of new technology and product development, manufacturing and marketing. These committees were chaired by members of Canon’s management committee, which gives them the ability to ensure consistency and communicate improvements throughout the organisation and into the different business units. (iii) Development of a global information system: Canon developed the GINGA system to interconnect all parts of the organisation into a global database to facilitate the timely flow of information among managers in all the company’s locations around the world. Canon’s efficient vertical communications structure with a lateral one will facilitate direct information exchange among managers across businesses, countries, and functions1. Strategic perspective The strategic perspective of Canon has traditionally been inside-out orientated. The company had a product focus whereby it deploys its technological capabilities to develop a diverse range of products, which it then markets on the strength of its brand through a wide range of dealer network and direct sales channel. The advantage of this method for a company like Canon is that it is able to leverage its expertise to develop a wide range of unique products. The costs associated with such developments would relatively be lower as it leverages on existing capabilities. The experience gained in the use of the underlying technology should result in high quality products. There is however the potential danger that the company may be unaware of changing trends and requirements in the market and therefore be unable to respond swiftly, giving competitors an advantage. It would appear however that Canon’s strategy is not exclusively inside-out, but has some elements of market focus. The development of the personal copier market for instance was based on an identified need in the market, with a clear description of the features of the product that would meet the need. This was clearly base on an outside-in approach. In addition, one of the major reasons that Canon values its dealer network is because it enables that company to understand and respond to customers needs. Diversification into the computer industry Based on the capabilities of Canon in the early 1990s, the company should have a good chance of doing well if it focused on the computer industry for the following reasons: (i) The company has demonstrated a strong ability to develop new technological innovations on the back of its existing technologies. With its  expertise in electronics, optics, fine chemicals and semi-conductors, Canon has the potential to develop quality computer systems that will compete favourably in the market. (ii) Canon already has a well-established brand name in home and office automation products through its range of copiers, facsimiles, electronic typewriters, laser printers and word processing equipment. The company will probably succeed in linking these discrete products into a multifunctional system. With the quality associated with the brand, its strong dealer network and direct selling experience, the market is very likely to give such a system a chance. (iii) Canon has also demonstrated the ability to buy in technology through its strategic alliances. This capability, with its low cost, high quality manufacturing should enable Canon to develop competitive computer systems. Apart from computers, the company should consider products that can utilise the company’s existing technological capabilities and dealer networks, such as DVD, televisions and similar products. Is Canon successful? From a variety of perspectives, Canon can indeed be regarded as successful. It effectively damaged the dominance of Xerox over the copier market, developing its market shares during the period. It also successfully diversified from being a camera company into a multinational, multi product company offering a range of high quality products to its global customers. The Canon brand name is well respected across the globe. Financially, the company recorded consistent growth in sales and profits over the review period. A review of the company’s financial statements from 1998 to 2002 showed that Canon has continued to grow its turnover and net income. Conclusion and key learning points (i) Resource based approach: Canon’s success was largely driven by the  company’s ability to utilise its core competences to develop innovative products as a means of gaining competitive advantage. (ii) Continuous learning and innovation: Canon demonstrated the benefits of continuous learning. As it succeeded with the AE-1 camera, its researchers and engineers further developed new expertise in microelectronics (to produce the electronic calculator), the new process (for copiers), cartridge based technology (for the personal copier and later the desktop printer) etc. These enabled the company to diversify its range of products; which was one of the reasons for its growth and success. (iii) Strategic value of partnerships and joint ventures: Canon effectively used these for acquiring technologies, developing markets, mitigating foreign trade tensions and reducing costs. (iv) Corporate level strategy: as the company developed into a multi-product and multinational corporation, the corporate level strategy remained the vehicle through which the global organisation was managed and integrated. (v) Strong monopolies can be broken: with over 93% market share in the 1970s and a brand name that was synonymous with copying, it would appear that the positional advantage of Xerox was unassailable. Canon demonstrated that such monopolies (when not imposed by government) can be broken through the introduction of innovative and quality products. By introducing the personal copier, the company also demonstrated the potential impact of one firm to completely change an industry.

How Austen creates her novel “Pride and Prejudice” Essay

Jane Austen was extremely modest about her genius, describing her work to her work to her nephew Edward as  Ã¢â‚¬Å"That little but (two inches wide) of ivory in which I work with so fine a brush as produces little effect after much labour.† Although the world of her novel â€Å"Pride and Prejudice† is confined to a small section of society comprising of country-gentry and lesser aristocracy of England in the opening of the 19th century, the novel itself shows page by page how interesting life could be, how fascinating life’s twists and turns are, how significant the trivialities are to those concerned. The range of Austen’s novel is limited by her own circumstances, her own sex, and her position in the society. But the little world she writes about, she knows inside out. She fills her little world so artfully that when we are in it we do not long for anything else and we feel its fullness as well. She practiced what she preached. â€Å"There are four families in a country village† is the very thing to work on. She sticks to what she knows and is refusing to include in her novel what does not properly belong to village life; she is an artist. Austen has an acute interest in personalities, her field is the human heart. Therefore, although she writes in the years of war between England and France while Napoleon was changing the map of Europe, in her novel we find not mention of â€Å"Britain at war.† In â€Å"Pride and Prejudice† soldiers like Wickham, come to Meryton to provide, in a sense, amusement for the girls. Austen thus does not impose anything harsh or unnecessary on her novel; this alludes to the artistic unity of her creation. She consciously limits herself and does not write anything beyond her experience. It may well be mentioned here that in â€Å"A Room One’s Own† Virginia Woolf pays a rich tribute to Austen by mentioning that novels like â€Å"War and Peace† could never be written by any female novelist, but certainly no Tolstoy could ever write the novels of Jane Austen. Austen deliberately and wisely limits herself to a few families and a limited number of characters in â€Å"Pride and Prejudice†. Her characters live in comfort in country houses; their lives consist of holding balls, attending parties, visiting each other’s house and thus amusing themselves. In that society even a small event is given a higher importance. Thereby a ball at the Bingleys or at the Lucases is eagerly anticipated and minutely analyzed. Austen chooses her characters from very ordinary life. Her characters range from the proud aristocrat Darcy to the dull-witted Mrs. Bennet, from the good-natured Jane to the hypocritical Miss Bingley. The men-folks in her novel do not in fact do nay work whereas the young girls are always in pursuit of good husbands. The girls have somehow managed to turn themselves into husband hunting butterflies. Distant Pembrly, Netherfield and Rosings are the upper limit, whereas Sir W Lucas and Lady Catherine Debourgh are highest in rank, the still higher estates and greater aristocracy are not mentioned in the novel, since they little effect Meryton and Derbyshire. The way Austen treats her characters is satiric. Her views of life are therefore always satiric; the passionate and tragic aspects of human life are somehow discarded. Only such characters are chosen that could be satirically treated. This satiric vision of life is a limitation on Austen’s part. Critics sometimes mention that Austen â€Å"Banished nine-tenth of life, and gave us people who never work, or fight or die, or starve or go crazy.† In the view of that above-mentioned statement we find that people in â€Å"Pride and Prejudice† engage themselves in doing nothing. Mr. Darcy apparently seems to have some work to do when he is at Pemberly, the work he does there is obviously connected with his estate. Mr. Gardiner revels in fishing only. Mr. Bennet, as we are told, takes one of his farms but only emerges from his library when he needs to settle some family affairs. Mr. Hurst’s motto of life is â€Å"High living and little thinking.† Reading has a place in family entertainment and since all the novels are heard at family gatherings, the writers take care to fill up pages fit for family consumption. In fact, Austen’s knowledge of men’s ways limited, but she knew how to use  her limitation. In â€Å"Pride and Prejudice† men come and go, and sit and chat when in front of the ladies; Austen does not pursue them into their personal world. We may see Fitz William Darcy and Bingley set off in a carriage but what they discuss is never reported if no woman is present. Despite Austen’s failure to present the many facets of men’s life, she is successful in providing an illuminating insight into some of the most significant characters like that of Darcy and Bingley. For instance, Darcy’s transmigration from a proud and snob person to a compassionate and reliable one is shown with perfect dexterity. In this novel Austen does want to compete with students of political economics, or social problems. The life and its complications that she depicts are just as what she experienced as a woman. Quite naturally her themes in this novel center the complex role of money and love in marriage. In doing so she even consciously avoids any discussion on philosophical or social issues. A simple plot concerning a few number of people is woven in this novel. That Austen has no wish to exceed the limitation of her own is quite evident when we find that urban life is excluded from the novel only because she had not much experience of it. It is mentioned casually during Jane’s visit to London. We have also observed that no black-hearted villain ever makes an appearance in Austen’s pages. The greatest villainy that ever occurs in â€Å"Pride and Prejudice† is the occasional elopement of Lydia with Wickham. Wickham indeed lacks all those negative traits of character which could have made him a person of shade like that of Alec in Hardy’s â€Å"Tess of the D’urbervilles†. Therefore, Wickham’s possibility to be the only villain in â€Å"Pride and Prejudice† ends there. Still it is no shallowness or lack of insight on Austen’s part, which leads her to restrict the exploration of human nature to the apparent social level. Austen gives us in her novel an artistic unity in which nothing is forced, nothing is excessive. A simple plot proceeds bit by bit to the only conclusion possible. Her characters act and speak in a very familiar way as we can imagine. The characters are so true to nature and so well-balanced against constructing types that as they talk along the story we begin to  think that it would not matter if there were no plot. The central figures whose union we desire grow upon us as their mistakes and recoveries reveal the fineness of their spirit. Therefore, in Austen’s world there is a welcome for the sensitive reader who will accept it as it is and will not cry out for, in the words of one critic – â€Å"The moon of passionate embraces or the lightning of sword.†

Solar Energy Research Paper Example | Topics and Well Written Essays - 1250 words

Solar Energy - Research Paper Example ss of the lost radiation, the solar energy that reaches the surface of the Earth is 10,000 times the energy used by the people (Solar energy in McGraw-Hill Concise Encyclopedia of Science and Technology, 2004). The radiation which is scattered when it collides with gas molecules is termed diffuse radiation, whereas the portion that directly reaches the Earth’s surface is termed direct radiation. Clouds play an important role in the scattering of radiation and hence reduce direct radiation by 80 – 90%. Global radiation is defined as the total radiation, including the diffuse and direct radiation that reaches the Earth’s surface (Solar energy in McGraw-Hill Concise Encyclopedia of Science and Technology, 2004). Extensive research is being carried on the utilization of solar energy; and the chief aim is to develop technology and discover efficient ways to capture the low-density solar energy, and convert it to a form that would be useful. In addition, forms of energy, such as wind energy, biomass energy, hydro power and thermal energy that derive from solar energy, promise to generate clean forms of energy. At present, with the sole exception of hydropower, none of these forms of energy are being employed to any significant extent (Solar energy in McGraw-Hill Concise Encyclopedia of Science and Technology, 2004). Sources of energy that do not get exhausted and can be replenished are known as renewable sources of energy. Most of the renewable energy systems that are in use rely either directly or indirectly on solar energy. The direct sources include tapping the heat and light of the sun, whereas the indirect sources are wave power, hydroelectric power, and wind turbines (Renewable energy in Illustrated Dictionary of Science, Andromeda, 1988). With growing awareness, regarding the ill effects and the limitations of fossil fuels, which will eventually be totally consumed, there is a sustained effort to change over to a more eco – friendly economy that is

Bill and Bentham Essay Example | Topics and Well Written Essays - 500 words

Bill and Bentham - Essay Example of imprisoning the murderer and permitting him to live may result in more killings; therefore, the death penalty is considerable and appropriate for killers. The utilitarian theory does not support eye for an eye in the sense that, if a man kills another, he should also be killed. The death penalty here deters any other criminal from committing the same crime or the occurrence of a similar crime. In this case, death penalty takes someone’s life and would prevent him or her from taking more lives; thus, providing the greatest happiness to the greatest number of people. Utilitarianism holds that the best course of an action is that which maximizes happiness and reduce suffering (Bentham 67). The moral worth of an action, according to this theory is only determined by its result. Any action intended to control the population for the purpose of inflicting happiness and comfort to the remaining people would be considered ethical, according to the utilitarianism. If the action prevents suffering for people, any action can be taken to prevent high population growth and make people glad to live. However, they believe that population control is vital for improving the stipulation of the working class so that they may enjoy outcomes of capital accumulation and technological progress. The multiplication of jollies with respect to the growth in population would not inflict any immorality provided that everybody is glad about his/her live and that no suffering is encountered as a result of unemployment caused by overpopulation. According to the utilitarianism, it is illogical and unreasonable to eliminate from the end any pleasure and feeling of any sentient being. They argue that animal rights should be granted according to the level of a creature’s self awareness without considering their species. However, if this would be strictly observed, our diets would be affected as people would not want to kill animals for meat. Utilitarianism suggests that it is easy for human

While at Harvard he studied under James care. This motivated his studies on psychology hence came up with his research on ‘mind reading(Lefrancois 24). He continued with his research and until he was later invited to study at Columbia University. This made him not complete his education at Wesleyan University. While at Columbia, he was motivated by James Cattell who helped him in his animal research. He also got involved in other experiments about human and animal behavior. His interest in the department together with continued researches helped him come up with theories supporting human and animal behavior. He continued with his passion for psychology until he was awarded a doctorate in 1898 on ‘Animal Intelligence. He used cats, dogs and chicks to support his thesis. Upon completing his education, he worked at Case Western Reserve University for a short period before becoming a psychology professor at Columbia University in the teachers College department.

History vs. Hollywood Cleopatra VII Term Paper Example | Topics and Well Written Essays - 1000 words

History vs. Hollywood Cleopatra VII - Term Paper Example Hence, Hollywood’s version of history is a combination of both fact and fiction. The substance of this prose will focus on Cleopatra, one of the most celebrated personalities both in the ‘real world’ and the silver screen. The latter was portrayed by Elizabeth Taylor in the 1963 adaptation titled â€Å"Cleopatra†. The movie closely follows the actual events but as is expected, there are some aspects that are spiced up, exaggerated or simply omitted due to the lack of appeal. Contrary to eminent historians, Cleopatra’s flawless beauty is the prime theme of the movie that is actually why men were drawn towards her. However, in reality Cleopatra’s beauty was neither jaw-dropping nor capable of driving men insane. In truth, Cleopatra wasn’t the beautiful lass that Elizabeth Taylor depicted her to be; in fact, she was a physically unattractive woman, who used her wit and wisdom as her primary tools of seduction (Grout 2012). The characterization of Caesar was also erroneous as he had never wished to be made emperor or dictator; it had been one of the fears held by the senate that eventually lead to his assassination. Furthermore, the movie also depicted how Caesar and Cleopatra’s affair had become increasingly public and the fact that Cleopatra bore him a son named Caes arion. In the movie, it is shown that Caesar publicly accepts his illegitimate son, Caesarion. Whereas in reality, Caesarion was never acknowledged by Caesar and much to Cleopatra’s ire, Octavian; Caesar’s nephew was proclaimed his heir. Caesar and Cleopatra had never married each other unlike the movie depiction. Historians have stated that Cleopatra’s and Caesar’s relationship was more of a political alliance than a romantic one that suited both individuals; their relationship is greatly dramatized in the movie. Nevertheless, the movie plot still followed the actual events closely and it did incorporate some very interesting details of history. The method through

COLOURIMETRY PARACETAMOL Essay Example | Topics and Well Written Essays - 1000 words

COLOURIMETRY PARACETAMOL - Essay Example Colourimetry is an extremely useful technique in establishing the concentration of substances. This is achieved by preparing a known concentration series of about 4 solutions, after which their absorbance is determined after the addition of colour by a reagent. The absorbance values give a calibration curve from which the concentration of an unknown substance is established. This technique is useful in the determination of metal ions alloys and biological fluids. Numerous industrial and clinical experiments report the successful usage of colorimetric procedures in the establishment of the concentrations of chemical substances. For example, the determination of vitamin E in food, trace amounts of platinum in glass, flavonoids in food, and detection of alpha fetoproteins among many other uses. Paracetamol (4-acetamedophenol) is a commonly used painkiller that lessens the temperature of fever patients. Its pain reducing effects are known as analgesic effects whereas its fever reduction action is called the antipyretic effect. Numerous over the counter medications contain paracetamol especially those meant for the relief of colds and flu. The most common form is the 500 mg tablet though other formulations such as suspensions and suppositories also exist. Paracetamol is quickly taken in from the gastrointestinal tract and attains peak plasma concentrations in about an hour. The cytochrome P450 system metabolises it into N-acetyl-p-benzoquinamine (NAPQI), a toxin that is entirely detoxified through conjugation with glutathione and excreted. Paracetamol is a fairly safe drug. However, doses greater than 10 grams have been reported to cause toxicity (Bose et al. 2005). This experiment aimed at using colourimetry as a chemical technique to make a calibration curve of absorbance a gainst concentration for known paracetamol concentrations and using it to obtain the concentration of paracetamol in the sample with the unknown concentration. Materials and Method 100 ml of 0.002M paracetamol solution was prepared by dissolving the right quantity of the drug in 10 ml of sodium chloride solution and topping up to 100 ml. This was the stock solution for the experiment. 1.0 ml of 6M HCl and 2 ml of 10% sodium nitrite were added to each of the seven labelled test tubes. Paracetamol and water were then added to the tubes in predetermined quantities after which the tubes were methodically mixed and allowed to rest for about 2 minutes. 2 ml of 15% sodium sulphamate were carefully added to the test tubes followed by 2.5 ml of 25% sodium hydroxide. The tubes were shaken for 15 seconds and allowed to stand for 2 minutes. This allowed all the bubbles to disperse. The absorbance of the contents of tubes 2 to 7 was then read at a wavelength of 430 nanometers using tube 1 as the blank. The values of absorbance were recorded for each concentration of paracetamol. A calibration graph of absorbance against concentration (mol/L) was then plotted and used to approximate the concentration

Describe how studying macroeconomics has helped you understand an Essay

Describe how studying macroeconomics has helped you understand an issue - Essay Example Based on the fact that I am pursuing a course in economics, my dream has always been to become one of the most successful economists in the country. Being a successful economist would involve being a Chief Executive Officer of a manager in the most respected organizations in the world. These roles necessitate one to have a wide range of knowledge in macroeconomics as well as other fields associated with economics. Being a top official in a highly respected organization involves a lot of interviews in televisions and radio stations. In doing so, an individual offers insight in the happenings of his organization and hence this can be considered a form of marketing. Furthermore, one of the units learnt in macroeconomics is leadership. Therefore, learning macroeconomics have enabled be to learn and gain leadership skills and abilities. Learning macroeconomics will ensure that I familiarize myself with all aspects of preceding and current economic issues of benefit in my future role as a top executive. Successful organizations in all parts of the world are governed by distinct rules and regulations. For managers to implement plans of actions geared towards enhancing and maintain organizational structures, incorporation of skills and knowledge in macroeconomics is critical. The study of macroeconomics involves investigating behaviors of various organizations and other successful institutions (Madariaga, 2005). Therefore, learning macroeconomics presents me with knowledge on how to create and implement organizational rules and guidelines associated with macroeconomics. In general, the study of Macroeconomics is involved with investigating comportment, performance, or conduct of the economy. It would be hard for me to implement economic policies without understanding various market conditions such as fluctuating prices of commodities and services. Conditions in the economy are always changing. This can be attributed to the current advancements in technology

English Technology Essay Essay Example for Free

English Technology Essay Essay The amazing thing about cell phones is that they are no longer just used for calling or texting. They have become an indispensable multi-tool wonder. Today’s cell phone is cutting-edge technology at your fingertips. With this in mind, should students be permitted to use cell phones in school? I believe they should not just be permitted to use cell phones; they should be required to use them. Cell phones don’t just allow students to stay connected with family and friends, they are also an excellent learning resource, and they encourage the responsible use of technology. To begin with, cell phones make it possible for students to stay in touch with family and friends. A student can call home and ask a family member to bring them a forgotten assignment or lunch money or to come pick them up if they are sick. Also, cell phones allow parents to keep track of their children’s whereabouts before, during, and after school. And, of course, there’s always the possibility of a student needing to contact a parent because of a dangerous situation. Thus, having a cell phone is like having a guardian angel. Students can also connect with friends, but not just because it’s a fun thing to do; A teacher can ask to text or email friends when they are absent to let them know what’s going on in class and to inform them of any homework. When used responsibly, a cell phone can be an excellent communication tool. Also, cell phones – especially smart phones are a great learning resource. Students can use tools such as the calculator, a map finder, and the calendar. You can use cell phones for all classes to keep track of homework. Instead of having to go to the computer lab teachers can let students use their smart phones to do research when doing group work, or working on a project. For example, if you have to study for ecology you can research on local jobs having to do with protecting the environment right from your classroom seat. Plus there are lots of great learning websites – including essay-writing websites – we can use to supplement the learning in classes like English. Cell phones are a quick and easy way to incorporate technology in the classroom. Finally, cell phones encourage the responsible use of technology. Students can learn when and how to use their cell phones to enhance their learning. They will become more independent in their work and more motivated to learn. Students like being allowed to make choices, and they understand consequences. If a student is texting when he/she should be paying attention to the teacher, the teacher should take the cell phone temporarily away. No big deal. Before a test, all cell phones should be placed on the teacher’s desk with no problems. By allowing the uses of cell phones, students will feel like they are being treated like responsible young adults, and they will appreciate that. If teachers are patient, understanding, and consistent, students will surely become responsible users of technology in schools. In conclusion, people who oppose the use of cell phones in school do it because of the disruptions and distractions cell phones can cause. But we must accept that we live in a world of technology and that cell phones are an important and very useful part of that world. We miss out if we fail to take advantage of the educational power of the cell phone. All in all, cell phones improve communication, provide learning resources, and encourage appropriate use of technology. Teachers and administrators must find ways to incorporate this excellent multi-tool in our schools. As you’ve learned from this essay, it’s really not that difficult. Let’s make the most of the day and age we are living in.

Memory Units And Memory Hierarchy

Memory Units And Memory Hierarchy Memory organisation is combination of several memory devices efficiently. Memory devices are combined and organised based on their characteristic such as access time, speed, storage capacity, physical size and cost per byte. Memory devices organised in such a way that computer system should operate at highest speed, provide bulky storage capacity, smaller in size and less in a cost. Memory organisation uses primary memory devices and secondary memory devices. 3.2 Memory Unit Memory unit is storage unit of the computer system. It stores content such as instructions (codes) and data for temporary or permanent purpose. It is used to stores content and to retrieves the content when needed by CPU or user. Memory unit includes two types of memory: primary (main) and secondary. Instruction or data given by input devices is first getting stored in the primary memory. Further users saves processed (executed) data in the secondary memory. Primary memory is volatile (temporary). It is faster than secondary memory. It includes RAM and ROM. It is directly accessible by CPU. Secondary memory is non-volatile (permanent). It includes several secondary storage devices such as Hard Disk Drive (HDD), Floppy Disk Drive (FDD), CDROM, and DVD and so on. Figure 3.1 shows memory unit and communication line with other units. Note: Volatile memory loses its content when computer loses power. In non-volatile memory power loss of computer does not affects content. Input Unit Process Unit Output Unit Primary Memory Secondary Memory Memory Unit 3.3 Memory hierarchy Memory organisation includes various memory devices. These devises are structured in a hierarchy based on the characteristics of memory devices. Memory hierarchy explains the sequence of accessing memory device while processing, in the computer system. Memory is structured in the hierarchy in such a way that computer system should give excellent performance. Figure 3.2 shows Memory hierarchy. Hierarchy is made on the basis of characteristics of memory, they are listed as follow: Access Time Time taken by memory to read or write data. It is measured in milliseconds (ms) or in nanoseconds (ns). Memory size It is amount of memory. Measured in KB, MB, GB or TB. Cost per byte It is cost required to access per byte. Transfer bandwidth It is speed of the memory. It measured in MHz, GHz. Unit of transfer Data transfer rate. Measured in Kbps, Mbps or Gbps. Increasing speed and cost per bit dcreeasing sisize Registers in CPU Level one cache Level two cache Main memory Virtual Memory Increasing Size, decreasing speed and cost capacity Secondary Storage devices Figure 3.2 Memory Hierarchy Memory hierarchy includes CPU registers on the top. Register provides fastest data access and it is one of the most expensive memory location. Second and third levels are level-1 and level-2 cache respectively. The level one cache is small in size (4 KB to 32 KB) though much larger than register. It is fixed on CPU chip so user can not expand. The level-2 cache is present on some CPUs only. It is much larger than level-1 cache. User can not expand it as it is fixed on CPU chip but it is cheaper than level-1 cache. Virtual memory is part of disk drive, which simulates to Random Access Memory (RAM). Disk drives are less expensive; so cost per bit is significantly less. Secondary storage devices are such as Hard Disk Drive (HDD), Floppy Disk Drive (FDD), Compact Disk Read Only Memory (CDROM), Digital Versatile Disk (DVD) and tape drives. It is bit slower. 3.4 Memory types Basic purpose of memory is to store content. Still memory is available in different types. Basic type of memory is primary memory and secondary memory. Types are made based on memory characteristics and its role in the computer system. Primary memory is the first memory used by CPU, so it should be faster and easily accessible. To make primary memory as per the requirement, memory organisation includes RAM and ROM as primary memory. The main use of secondary memory is use to store users data permanently. Speed of secondary memory can be compromised, but storage capacity should be excellent. So memory organisation includes HDD, FDD, and CDROM and so on as a secondary memory. Figure 3.2 shows types of memory. 3.4.1 Primary Memory Primary memory is access directly by CPU. Primary divided in to two types RAM and ROM. Primary memory should be faster and easily accessible. RAM RAM is a primary memory used in the computer. RAM is the main memory of the computer system. It is volatile since its content is accessible only as long as the computer is ON. The content of RAM is cleared as soon as computer is powered OFF. It is at third place in the memory hierarchy. Operating system, application program and running data are loaded in the RAM. CPU directly accesses the RAM. Types of RAM are as follows: Static Random Access Memory (SRAM) SRAM is made with several transistors, usually four to six, for each memory cell. It does not require refresh time as capacitors are not used. It is much faster and costlier than DRAM. Computer system use SRAM as cache memory. DRAM (Dynamic Random Access Memory) It has memory cells with a paired transistor; it uses capacitor, as capacitors slowly leaks with as they stared discharging, so need periodic refresh. It is slower and chippers than SRAM. It is much denser (stores many bits per chip). It requires less power and generates less heat as compared to the SRAM. DRAM is available in several forms such as SDRAM, then DDRAM to RDRAM. Read Only Memory (ROM) ROM is non-volatile primary memory. Data written on ROM can not delete or overwrite. Data is burned on the ROM as firmware. ROM memory is used in the computer system to write firmware for example BIOS program. Types of ROM are as follows: Programmable read-only memory (PROM) This type of memory is one time written memory. Once program is written can not be change. Erasable programmable read-only memory (EPROM) Data written on EPROM can be erased. Ultraviolet is used to erase the data written on PROM. Electrically erasable programmable read-only memory (EEPROM) It is same as EPROM but to erase data entirely it requires electrical signal. So not require to remove from computer. Data can be erased or over written it the computer itself. 3.4.2 Secondary Memory A secondary memory is non-volatile. Secondary memory used to save users data permanently. Devices used as secondary memory are HDD, FDD, CD, DVD, Tape drives and so on. Secondary memory is at sixth place in the memory hierarchy. Devices used as secondary memory are listed as follows: Floppy Disk Drives (FDD) Used as magnetic, portable memory device. It stores maximum 1.44 MB data. Earlier it used to transfer data among computer systems. Hard Disk Drives (HDD) HDD is fixed, magnetic memory device. It is vital in the computer system because Operating System and users data is saved on the HDD. Storage capacity of HDD is vendor specific. CDROM and DVDROM Are optical memory units used for transferring data and programs among the computers. CDs are available in the size 650MB, DVDs are available up to 4 GB in a size. Tape drives Are usually used for data backup purpose. 3.6 Cache Memory The cache is small amount of memory with high speed. Cache memory keeps data and code (introductions) that are used by CPU often. Use of cache memory reduced the waiting time of CPU that makes CPU more effective. SRAM is used to create cache memory. SRAM does not required refresh as it does not use capacitors as DRAM, it is 10 times faster than DRAM. Cache is of two types Level-1 that is placed ion the CPU. Level 2 cache is optional some processors have this type of memory that is some time placed inside the CPU or placed near by CPU. To execute next instruction, CPU first check cache memory for the same instruction if that instruction is not available then it goes further. Note: DRAM is made up of capacitors which need constant refreshing to preserve data. SRAM uses flip-flop circuit that does not require refresh. 3.6.1 Cache line replacement Algorithms While a new line is loaded in the cache, one of the existing lines must be replaced. Direct mapped cache, same block from line is removed take place for new one. In associative cache, it can search for another place. Four of the most common line replacement algorithms are as follows: LRU (Lease Recently Used) the cache line that was last referenced in the most distance past is replaced. FIFO (First In First Out) the cache line from the set that was loaded in the most distant past is replaced. LFU ( Least Frequently Used) the cache line that has been referenced the times is replaced. Random a randomly selected line from cache is replaced. Note: The most commonly used algorithm is LRU. Cache Terminology Cache use few terminology for operation are as follows: Hit A cache access finds data the cache memory Miss A cache access does not find data or instruction, forcing access to next memory down in memory hierarchy. Miss ratio Percent of misses to data compared to all accesses. Hit access time Number of clocks to return a cache hit Miss penalty Number of clocks to process a cache miss. Virtual Memory Operating system enables a process through which space of hard disk drive can be simulate to RAM. The HDD space used as RAM is known a Virtual Memory. As cost per byte of HDD is less, so virtual memory is beneficial to run many large programs that need more memory. Access time of RAM is in nanoseconds but virtual memory gives access time in milliseconds. It is much slower than RAM. Figure 5.1 shows operation of virtual memory. Virtual memory uses paging and segmentation terminologies. Terms used by paging are as follows: Virtual address- Address used by application program from virtual memory. It is composed of page number and page offset. Physical address Address of physical memory. Page virtual space divided into fixed-size pages. Frame Physical memory divided into fixed frames size. MMU Memory Management Unit (MMU) used to map virtual address to physical address. Page table Each process has its own page table. Each page table entry contains the frame number of the corresponding page in main memory Figure 3.4 Virtual memory operations 3.8 Chapter Review Questions Which of the following is primary volatile memory?

Henry Viii And Anglicanism Religion Essay

Henry Viii And Anglicanism Religion Essay Many individuals today believe that Anglicanism began with Henry VIII for his simple wish of divorcing his wife in hopes to produce a male heir. Certainly it was established in the era of King Henry VIII and Elizabeth I, however there were many other influences that contributed to the creation of the Church of England. These influences date back to the early years of Christianity in the British Isles. After doing much analysis on this history, it is safe to say that King Henry was not the only creator of Anglicanism; he was only a contributor to its formation and the final step to its beginning. It is said that among the soldiers living in Britain, some were of Christian faith. St. Alban, the first English martyr, was killed in 209 CE and therefore the Christianity was certainly present by 200 CE. In 400, when the Romans left Britain and many invaders arrived, in the West and North the Celtic people maintained their faith and culture. A type of Christianity grew among these individuals which still influences our spirituality to this date. Celtic Christianity dated between 400 1000 CE. These stories and legends of the Celtic church are told by Saints such as: St. Ninian, St. Calumba and St. Brigit.Governed by chiefs or kings, Celtic society was organized on tribal lines. The Celtic church was controlled around monasteries ruled by abbots who ordained as priests celebrated the sacraments in the monasteries. The land for the monastery was often provided by the tribe or family unit. By 431, Ireland had received its first bishop. The government of the Irish church was controlled by the abbots however by the 1800s .The abbeys promoted learning, taught the children, and fabricated spectacular religious art in the manuscripts, metalwork and stone carvings. The Anglican spirituality had a lot of influence from the Celtic spirituality. There was a very strong sense of the presence of God in everyday life of the Celtic Christians. In all of their daily activities, God is found. There are a vast amount of prayers from the Celtics that have these examples. There is an example in the book A World Made Whole (Fount, 1991): I will kindle my fire this morning, In the presence of the holy angels of heaven. This quote from the prayer shows that God is in their everyday lives, God is not forgotten. The goodness of nature and of human nature are a part of true Celtic beliefs. It sees human as being full of potential and made in Gods image. Jesus came to free our world from its evil forces. This is an optimistic view fits well with the Anglican understanding of creation, i ncarnation, and redemption. Celtic Christianity has a strong sense of the unity. It insists that we are encircled on our pilgrimage by faithfully Christian individuals of an earlier era. God, the Trinity, the saints of old-all are near us and are always accessible to us in our prayers. Celtic Christianity is full of stories, images, art and music. With the arrival of St. Augustine at Canterbury in 597, Roman Christianity returned to Britain. This tradition and form of government spread throughout England steadily. Although Celtic Christianity was slowly concealed by Roman practice, many customs and traditions were kept. It was an era of change and turmoil in the church during the 1500-1600s in Europe. There was dissatisfaction with papal government and abuses of church traditions. Furthermore the availability of new translations of Scripture from Latin into other languages fashioned a craving to look over the ancestry of the Christian faith and a desire to return to the basics of Christian ideas. In Europe individual figures like Ulrich Zwingli, John Calvin and Martin Luther encouraged doctrinal and organizational reform. England knew of the effort of these reformers and had the Scriptures in English. However, the church was not extremely affected by them. In reality Henry VIII received from the Pope in 1521 the title Defender of the Faith for his paper criticizing Martin Luther. However, the King was going through some political difficulties. His marriage of almost 20 years to Catherine of Aragon had produced only one living child, their daughter Mary. Henry became increasingly worried because he n eeded a male heir for the throne. Henry decided to divorce his wife and that he was going to marry Anne Boleyn. Securing an annulment and obtaining a papal dispensation to remarry was not an impossible request, however it made Henry anxious. But European politics launched a problematic factor; Catherines nephew was the Emperor Charles V. The Pope was being threatened by the Emperor and so could not grant Henrys request. Henry decided then to remove the church in England from the control of foreign powers. Acts of Parliament were passed, Henrys marriage was declared invalid, and he married Anne Boleyn. The Pope rapidly removed Henry. To gain [a son], he separated the Church of England from the Roman Catholic Church and so established the Protestant Reformation in England . Henry took rising control of the church, suspending the monasteries and moving their riches to the crown and declared himself the head of the church in England. Henry ordered the English Bible located in all church es but stayed very conservative in matters of spiritual traditions. Henry was succeeded in 1547 by his son Edward VI. Edward had been well-informed by teachers with Protestant understanding. Throughout his reign the church was progressively more influenced by Lutheran and Calvinist tradition. In 1549, the first Book of Common Prayer, drawn up by the Archbishop of Canterbury, Thomas Cranmer, was certified. The Act of Uniformity made its use obligatory in all churches in England. This book has become the normative statement of Anglican theology and practice. The book was a compromise between traditionalists and reformers. In 1552, a second Book of Common Prayer was issued. It followed more Protestant ideologies. During the reign of Edward VI, many Articles were published to identify the position of the Church of England on a vast amount of issues. This was an attempt to define a connection between the Old Catholic ways and the new Calvinist reforms. The 42 Articles were proposed in 15 52 and these were not accepted. However in 1559, during the reign of Elizabeth, the Thirty-nine Articles were accepted as a balanced statement of the Anglican position on certain uncertain issues. Edward was then succeeded by his half-sister Mary. As the daughter of Catherine of Aragon, Mary wanted to return England to the worship of the Roman Catholic Church. During Marys reign, many reformers were executed however on her death, her half-sister Elizabeth became Queen. She wished to restore stability to the country, while at the same time preserving England from foreign domination. The church then should retain its heritage but remain free of the rule of the Pope. The form of liturgy, the three-fold order of bishops, priest and deacons, the sacraments were all retained. But the differences were that services were in English, the reading of Scripture was encouraged, and clergy could marry. The third Book of Common Prayer was issued in 1559. The aim of the Elizabethan church was to br ing stability to both church and state. The Church of England held together in one family a variety of views by avoiding narrow definitions. Richard Hooker, 1554-1600, was the apologist for the emerging Anglican position. The Anglican approach to theology, the balance of Scripture, tradition and reason was defined by his Treatise on the Laws of Ecclesiastical Polity. He saw the church as changing and adapting. The church structures its existence by looking at scripture and tradition in the light of reason and experience. Renewal and progress in the 18th century placed a new tension on personal conversion, salvation by faith in Christs agreed death, the sole power of Scripture, and the significance of the lecture of the Word. Influenced by evangelical clergy, the missionary movement brought the gospel to all parts of the world. At home in England, evangelicals played a major role in the abolition of slavery and the reform of social conditions. In the 19th century, the Anglo-Catholic restoration brought a new emphasis to the liturgical and sacramental life of the church. The Oxford Movement aimed at restoring high church ideals to the Church of England. In this movement we have the Low Church that of being the Anglican Church of Ireland and High Anglican Church that being the Church of England. This group of reformers was sometimes called Tractarianists because of the series of writings, Tracts for the Times, in which they set out their views. The movement emphasized the catholic and apostolic nature o f the church, looking back to its historic roots. It placed new importance on the liturgical and sacramental life of the church; the introduction of vestments, candles, ceremonial and ritual followed soon after. Anglo-Catholics were involved in ministry to the slums of large English cities, and in missionary work around the world. During this period, religious orders of monks and nuns were re-established, and this continues in the Anglican Church to this day. In conclusion, after much research it is understood that The Anglican Church was created by many contributions and ideas that dated back to the early years of Christianity in the British Isles. King Henry VIII was the final contribution to its foundation, but would not be here if it were not for the Celtic Spirituality. However to this day there are issues with the Anglican Church. The Anglican Church though would have liked to settle once it left the Roman umbrella will not be in a settle state. It seems as if equilibrium cannot be maintained and there is still controversy to this day with this religion that was created many years ago.

monkeys :: essays research papers

I like monkeys. The pet store was selling them for 5Â ¢ a piece. I thought that odd since they were normally a couple thousand each. I decided not to look a gift horse in the mouth. I bought 200. I like monkeys. I took my 200 monkeys home. I have a big car. I let one drive. His name was Sigmund. He was retarded. In fact, none of them were really bright. They kept punching themselves in their genitals. I laughed. Then they punched my genitals. I stopped laughing. I herded them into my room. They didn't adapt very well to their new environment. They would screech, hurl themselves off of the couch at high speeds and slam into the wall.Although humorous at first, the spectacle lost its novelty halfway into its third hour. Two hours later I found out why all the monkeys were so inexpensive: they all died. No apparent reason. They all just sorta' dropped dead. Kinda' like when you buy a goldfish and it dies five hours later. Damn cheap monkeys. I didn't know what to do. There were 200 dead monkeys lying all over my room, on the bed, in the dresser, hanging from my bookcase. It looked like I had 200 throw rugs. I tried to flush one down the toilet. It didn't work. It got stuck. Then I had one dead, wet monkey and 199 dead, dry monkeys. I tried pretending that they were just stuffed animals. That worked for a while, that is until they began to decompose. It started to smell real bad. I had to pee but there was a dead monkey in the toilet and I didn't want to call the plumber. I was embarrassed.I tried to slow down the decomposition by freezing them. Unfortunately there was only enough room for two monkeys at a time so I had to change them every 30 seconds. I also had to eat all the food in the freezer so it didn't all go bad. I tried burning them. Little did I know my bed was flammable. I had to extinguish the fire. Then I had one dead, wet monkey in my toilet, two dead, frozen monkeys in my freezer, and 197 dead, charred monkeys in a pile on my bed. The odor wasn't improving. I beca me agitated at my inability to dispose of my monkeys and to use the bathroom.

This report is intended to present the experimental and analytical aspects of wine chemistry with focus on fining agents. By testing these fining agents on wine samples, their overall effectiveness will be observed and discussed with respect to pH, Turbidity, Sediment level etc.This will help draw a valid conclusion as to the fining agent that has the greatest clarification effects on the tested wines and to what extent. 2. 0- Introduction: The ancient process of winemaking has captivated the human civilisation for thousands of years. Archaeological findings have shown that the earliest production of wine can be traced back to 8000BC in the regi on of modern day Georgia, Iran and Armenia (Merveonur, M. 2011). Since then the art of vinification has been continually evident throughout history with its significance highlighted in many of the world’s greatest cultures.Take for example the ancient Egyptians of third millennia BC that used wine for sacred ceremonies or the ancient Greeks that traditionally conducted symposiums (social parties) by drinking wine in large groups (Biers, W. 1980). Throughout the ages wine has undoubtabley been valued for its significance in society, culture and even religion, with its importance still prevalent in the modern world. In Australia, the exportation of wine currently contributes an astounding $6 billion dollars to the nation’s economy (Adams, P. 2005).In fact, Australia is recognised as the fourth largest exporter of wine in the world. The country’s eight constitutive states all commercially produce wine of high quality with vineyards occupying approximately 160,000 h ectares throughout Australia (Wine Australia, 2010). States such as Victoria and South Australia are internationally renowned for producing highly exquisite wines that undergo the finest vinification. The process of producing wine is one that involves multitudinous techniques and requires a thorough scientific understanding referred to as Oenology.Oenology is the modern study of winemaking encompassing everything from the initial fruit growth to the extensive chemistry behind the entire process (Boulton, R. 1996). Vinification ultimately consists of many biochemical processes that must be carefully monitored and controlled to ensure success. The primary chemical process involved in any wine is the initial fermentation which is responsible for the formation of ethanol. During this stage, common fruit carbohydrates such as glucose and fructose are converted to alcohol through anaerobic yeast respiration (Fugelsang, C. 1997).Ultimately, the yeast which are facultative fungal organisms provide enzymes that break down sugar molecules while releasing Ethanol and Carbon Dioxide as by-products through the exothermic reaction: C6H1206 —>2CH3CH2OH + 2CO2 + 115kj/mol. Winemakers will usually stop the fermentation process once a desired alcohol level is achieved however the fermentation can naturally stop after reaching a certain level of alcohol that subsequently becomes toxic to the yeast thus killing them (Smith, D. 2009). Once fermentation is over, many wines may display signs of turbidity or cloudiness.This is due to suspended particulates such as proteins, tannins, phenols or dead yeast cells that cause haziness in wine when not removed. These particles can precipitate out of the wine naturally under the influence of gravity however this is a lengthy process and those that want fast results rely on chemical clarification. Chemicals for the purpose of wine clarification are known as fining or flocculation agents and are widely used in the wine industry. These agents are commonly derived from Earths, Proteins, Carbons, Synthetic polymers, Polysaccharides and other substances (Zoecklein, B. 988). It is extremely important that a commercial wine be cleared of any suspended impurities so that it appeals to the consumer. Fining agents generally clarify the wine in three different methods including electrostatic attraction, absorption or enzymatic break down (Main, M. 1995). The most common method however is through electrostatic attraction as this is displayed by the majority of fining agents. Theoretically the suspended particles in wine all carry a corresponding electrical charge therefore by dding a fining agent of the opposite charge the particles adsorb to the surface of the fining molecule forming heavy clumps (refer to appendix figure 1). The clumps rapidly sink to the bottom due to their high density relative to that of the wine (Guerra, B. 2008). Ultimately, three fining agents were selected as test subjects for the experiment that w as to be conducted. These agents include: Bentonite which is aluminium phyllosilicate clay with a negative charge, Isinglass; a collagen derived from fish that carries a positive charge and Kieselsol/gelatine which is a fining agent utilizing both a positive and negative charge. 3. 0- Aim:The general aim of this scientific investigation is to assess the efficiency and clarification capabilities of three difference fining agents including; Bentonite, Isinglass and Kieselsol/Gelatine. The results obtained from the wines treated with fining agents will be contrasted to those obtained from the wine without the presence of a fining agent. This will indicate any trends in the data as to which fining agent is most efficient and if there is a great difference between the rate of clarification of the wines subject to chemical fining as opposed to the wine subject to natural clarification under the influence of gravity alone.By testing parameters such as Ph, Turbidity, Sediment level, Alcohol content and Electrical conductivity some relationships between the results obtained and variables will be analysed to justify the efficiency of the flocculation agents. 4. 0- Hypothesis: It can be hypothesised that all three fining agents will have noticeably different effects on the wine clarity. The ‘Kwik Clear’ agent is predicted to exhibit the greatest impact on clarification as it comprises of both Kieselsol and Gelatine which are agents of opposite charges.This will hypothetically create more lees as the negative and positive charges together will in turn attract more suspended particulates of either electrostatic charge. On the other hand, the negatively charged Bentonite agent is also expected to demonstrate immense fining capacity due to its great molecular surface area that will prompt the adsorption of high amounts of positively charged particles. The Isinglass agent is ultimately expected to perform less desirably as it is by nature a delicate, positively c harged agent with weak fining abilities due to it fragile molecular structure.Finally, the wine without the presence of fining agents (the control), will undoubtabley show the least satisfactory results in terms of clarification. Some sedimentation may occur due to the natural impact of gravity however this will be limited and substantially less in comparison to the wine treated with fining agents. 5. 0- Safety Analysis Due to the topic of this assessment (wine making), the laboratory has been used extensively for nearly all aspects of this assignment including the creation of wine and testing. Safety precautions must therefore be exercised together with strict lab etiquette to prevent dangers arising.Students must remember at all times to abide by the rules which include: 1. Conducting one’s self sensibly and responsibly at all time especially when handling chemicals of potent nature. 2. No food or drinks to be brought into the laboratory to prevent the possibility of contam ination with harmful substances. 3. Long hair must be firmly tied back to reduce the risk of exposure to corrosive chemicals (or the risk of contaminating the wine). 4. Safety goggles, aprons, lab coats and gloves should be worn at all times to minimise the risk of body exposure to chemicals especially the eyes. . All experimental instructions must be read and understood precisely before conducting the experiment. 6. Sitting on top of the laboratory benches is prohibited. 7. Sitting on chairs while performing chemical experiments is forbidden. 8. The labels of chemicals utilized must always be read so that one is aware of the risks and nature of the particular chemical. 9. Extreme caution must be taken when handling glass apparatus to ensure no breakage. 10. Any breakage or chemical spills must be immediately reported to the teacher so that the risk may be quickly contained. 11.Carrying chemicals or glass across the room is not advisable and carries a great degree of risk. 12. Runni ng whilst in the premises is strictly forbidden 13. All students must wear closed in shoes to protect feet from spills that may run down the benches. 14. All individuals must be aware of the nearest fire exits and have an understanding of how to use the fire blanket in case of emergency. 15. Any skin contact with chemicals must be quickly reported to the teacher and subsequently washed under running water for 20 minutes or the eye bath when contact has occurred with the eyes. 16.Any instructions given by the teacher must be followed without hesitation. Note: During the course of the wine making, student are required to perform titrations which require the handling of some extremely noxious chemicals including carcinogens, potent acids and allergens that must by all means be handled with immense care. Many chemicals also have the tendency to cause problems with the respiratory system when inhaled thus any chemical must be distanced from the nose or mouth. 6. 0- Equipment and Material s.

Pour sachets of yeast into a 750mL bottle with the addition of 2 tbsp sugar, 0. 5 tbsp acid and half-fill the bottle with water placing a balloon over the neck when finished. 2. Fill the bottle with water when the balloon has popped up. Replace the balloon afterwards. 3. Once the balloon ‘pops up’ a second time, put the bottle in the fridge. 4. Wash bucket, knife, working surface and all fruit with sodium metabisulphite solution. Avoid rinsing fruit! 5.Remove any really bad parts off the fruit. (it’s not a problem if the fruits are mildly squashed or discoloured). 6. Chop the fruit into approximately six pieces each and place into bucket. 7. Add/mix the following into the fruit: 0. 75 tbsp acid, 0. 75 tbsp nutrients, 0. 75 tbsp Pectinase or 7. 5 drops Pectinol, 7. 5mL Sodium metabisulphite, 150g sultanas, 6-8 bananas, 3 tea bags and 7. 5L water. 8. Leave to rest for 24 hours. 9. Once 24 hours have passed, ass half of the bottle of yeast from st ep 3 and 750g sugar to the bucket. Stir well, then put a plate on top of the fruit. This will keep it in the liquid.The whole thing should be covered with a damp towel. 10. Add an additional 1. 5 tbsp of sugar to the yeast bottle and fill with water. Replace the balloon in the process. 11. Begin stirring the bucket with fruit once a day for 3-4 days consecutively. 12. The funnel, strainer and fermenter must be washed with sodium metabisulphite solution for adequate disinfection. 13. Transfer the liquid contents of the bucket into the fermenter using the funnel and discard any solids in the process. 14. Any remaining liquid must be placed in bottles, stoppered with cottonwool in the neck and placed in the fridge. 5. Use sodium metabisulphite to fill the airlock to half of each chamber. 16. After a week has passed, use PVC tubing to transfer the liquid at the top into the bucket, ensuring the lees (sediment) is left at the bottom during siphoning. 17. Discard the lees, rinse out the f ermenter and then replace the liquid back into the fermenter. Use bottles from step 14 to top up the fermenter as needed. Taste and add 150 g of sugar if it is too dry. Also add 5mg of Campden tablets. (Warning: Campden sulphur allergies) 18.Repeat step 16-17 (which is a process called racking) about once a week for 3-4 weeks. If sugar added, a record must be kept of the exact quantity. 19. When clearing from the top of the wine has initiated, the airlock chambers are evening out and the hydrometer reading is between 1005 and 995, repeat step 16. 20. Taste the samples. If a sweet wine is desired, put 100-150g of sugar in a saucepan and cover with wine fermenter. Heats until the sugar has dissolved and then gradually add this to the wine until the desired balance of sweetness is obtained. 21.Add 10ml of Sodium metabisulphite and 1000mg of orange flavoured vitamin C (as a preservative). 22. Wash bottles and cork in the solution of sodium metabisulphite and shake out but don’t r inse. 23. Put wine into bottles and cork storing it in a cool dark place. **(refer to journal for information about the key ingredients of the wine making process) 7. 2- Addition of fining agents including ratio calculation: Isinglass Note: The wine used for each fining agent was racked moments before adding the agents. This ensured that any sediment formation with the fining agents would be easily noticeable and recordable. . Read the instructions on the back of the Brewcraft Isinglass bottle. These instructions stipulate that 10mL are mixed in 25L of wine with the 10mL firstly mixed in a 250mL aliquot before being added to the bulk. 2. The wine bottles used in this experiment contained 750mL of wine therefore calculations were performed to find how much Isinglass must be added to 750mL. 3. Firstly divide 10mL by 25,000mLwhich equal 4Ãâ€"10-4. 4. Secondly, multiply 4Ãâ€"10-4 by 750mL which equals 0. 3mL (this is the amount of Isinglass to be used for 750mL of wine). 5.To find how much of the 750mL of wine must be used to initially pre mix the isinglass before adding it to the bulk, the following was calculated: 25,000mL divided by 250mL equals 100; 750mL divided by 100 is equal to 7. 5. Therefore 7. 5mL of wine must be mixed with 0. 3mL of Isinglass before adding it to the 750mL bulk. 6. Extract 7. 5mL of wine using a small disinfected pipette placing this aliquot in a small beaker. 7. Extract 0. 3mL of isinglass with a small disinfected pipette and place it in the beaker with the 7. 5mL aliquot. 8. Mix the fining agent in the aliquot of wine for a few minutes making sure to swirl it as well. . Using a funnel, replace the mixed aliquot back into the 750mL bulk. 10. Label the bottle, indicating the fining agent used and the dosage. 11. Place cottonwool in the neck and return bottle to the fridge. **(refer to journal for information regarding Isinglass) 7. 2- Addition of fining agents including ratio calculation: Kieselsol/Gelatine (Kwik Clear) 1. Read the in structions on the side of the Kwik Clear box. These instructions specify that 2mL of Bottle A (containing Kieselsol) must be added per gallon of wine. 2mL of Bottle B (containing Gelatine) must also be added per gallon. . Simple calculations were conducted to find how much of Bottle A and B is to be use for the 750mL bottles. Firstly 1 Galloon equals 4. 5 litres therefore 4500mL divided by 750mL equals 6. 3. 2mL divided by 6 equals 0. 33mL hence, 0. 33mL of both Bottle A and B is to be mixed into 750mL of wine. 4. Premix is not required for Kwik Clear therefore the fining agents can be directly added to the 750mL bulk. 5. Using a small disinfected pipette, take 0. 33mL of Bottle A and place it directly into the 750mL wine. 6. Stir well, then wait approximately 30 minutes before adding Bottle B. . Using a small disinfected pipette, extract 0. 33mL of Bottle B and place it into the bulk. 8. Mix well then label the bottle to include the name of the fining agent in use and the dosage. 9 . Stopper the bottle with cottonwool and return it to the fridge until ready for testing. **(refer to journal for basic information about Kwik clear (Kieselsol/ Gelatine fining) 7. 3- pH testing: 1. Put on gloves and gather all necessary equipment. 2. Thoroughly disinfect the four beakers, the tip of the pH meter and the funnel with sodium percarbonate solution. 3.Run distilled water over the tip of the pH meter until a neutral ph of between 6. 5-7. 5 is reached (this will ensure that the pH meter is configured properly). 4. Carefully pour an adequate sample of wine in a beaker. 5. Slowly dip the tip of the pH meter and leave it in the wine until the pH value on the monitor becomes constant. 6. Record the value and return the sample of wine to its corresponding bottle using a funnel (make sure the sample is returned from the bottle it was taken from as it would be very undesirable to accidently mix the agents. This would corrupt the whole experiment). 7.Repeat steps 2-6 for all the wines. **(refer to journal for basic information regarding Ph-(power of hydrogen) 7. 4- Vinometer testing: 1. Put on gloves and gather all necessary equipment. 2. Make sure to disinfect the four beakers, the vinometer and the funnel with sodium percarbonate solution. 3. The vinometer testing requires handling of the wine with hands therefore the hands must be disinfected prior to testing or if gloves are worn, make sure the gloves are disinfected as well especially if used in prior tests. 4. While holding the vinometer over a beaker, pour wine into it so that the wine covers the entire vinometer. . Apply pressure using the thumb on the vinometer opening as though pushing the wine in (this will ensure any bubble formations are removed). 6. Once confident that no bubbles are evident flip the vinometer upside down allowing the wine to fall into the beaker. 7. Bring the vinometer up to eye level and read the scale after the fluid has settled (the level is sometimes hard to see as it is very thin). 8. Record the value; this is usually in %v/v alcohol. 9. Repeat steps 2-8 for all the wines. **(refer to journal for basic information regarding Vinometer (% alcohol concentration). . 5- Hydrometer testing: 1- Put on gloves and gather all necessary equipment. 2. Wash all four beakers, the hydrometer, the measuring cylinder and the funnel with sodium percarbonate solution. 3. Carefully fill the cylinder to about 80% with a sample of wine. 4. Gently lower the hydrometer into the wine making sure it does not touch the bottom or the side of the cylinder. 5. Record where the surface of the wine contacts the hydrometer. 6. Repeat step 2-5 for each wine ***(Note: The Hydrometer testing was done incorrectly thus giving inaccurate results throughout each trial.This mistake was only noticed after testing was concluded therefore there was no way of repeating the results. All results obtained a hydrometer reading of 1. 030 which indicates there has been a general mistake with the pr ocedure. The group decided not to use the Hydrometer due to this flaw)*** 7. 6- Turbidity testing (with tube): 1. Place gloves on both hands and gather all necessary equipment. 2. Wash the turbidity tube and funnel in the disinfectant sodium percarbonate solution. 3. Carefully pour wine into the turbidity tube by small increments at a time. 4.Look for when the black lines at the bottom of the tube become slightly visible just enough to see the lines. 5. Record the value at which the lines are slightly visible (this is the turbidity in NTU). 6. Repeat steps 2-5 for each wine. **(refer to journal for information about Turbidity) 7. 7 Sediment level (with ruler): 1. Carefully hold the wine bottle against and angle of strong light until the lees is visible (making sure not to disturb the sediment greatly). 2. Use a ruler to measure the sediment level from the bottom of the bottle to the point at which it finishes. . Record the results to the nearest mm. 4. Repeat step 1-3 for each wine (Note: Sediment measurement should be tested first before anything else so that the lees is not disturbed from movement 7. 8 Electric Conductivity (EC meter): 1. Put on gloves and gather all necessary equipment. 2. Thoroughly disinfect the four beakers, the tip of the EC meter and the funnel with sodium percarbonate solution. 3. Run distilled water over the tip of the EC meter until a reading of 0 is obtained (this will ensure that the EC meter is configured properly). 4.Carefully pour an adequate sample of wine in a beaker. 5. Slowly dip the tip of the EC meter and leave it in the wine until the Electrical conductivity value on the monitor becomes constant. 6. Record the value and return the sample of wine to its corresponding bottle using a funnel (make sure the sample is returned from the bottle it was taken from as it would be very undesirable to accidently mix the agents. This would corrupt the whole experiment). 7. Repeat steps 2-6 for all the wines. **(refer to journal for in formation about EC (Electric Conductivity) 7. EC Conversion to TDS using mathematical formula: 1. The formula stipulates that TDS (ppm or mg/L) = F x EC where F is a factor of 0. 6 and EC is the electrical conductivity in Microsiemens per centimetre. 2. The results taken by the EC meter in class are given in millisiemens therefore to covert to microsiemens simply multiply by 1000. 3. Take the number in microsiemens and multiply it by a factor of 0. 6 as stated by the formula. 4. This is the measurement in TDS (ppm). 7. 10 Alcohol Titration method: 1. Place a 10mL aliquot of wine in a 250mL volumetric flask ( using a small pipette). 2.Distilled water is then used to fill the volume up to the 250mL mark. 3. Take a 20mLaliquot from the 250mL solution and place it in a conical flask. 4. Step 3 must be repeated twice so that there are three flasks to use in 3 separate trials. 5. To every flask a 20mL aliquot of 0. 04 Molar Potassium Dichromate is added. 6. 10mL of 40% sulphuric acid is a dded to every flask with the aid of a measuring cylinder and the teacher (the teacher will have to do this step due to the potency of the acid). 7. Each flask should be stoppered loosely and heated in a water bath at 45-50*c. (water bath must not exceed 50*c). . Once 10 minutes have passed, remove the flasks and add 2 g of Potassium Iodine to all flasks. 9. Fill the burette with Thiosulphate solution (0. 1 Molar). 10. Begin the titration, titrating the contents of the flask with the 0. 1M Thiosulphate solution. When the brown colour of the titrated solution becomes green add 1-2mL Starch. The equivalence point is noticed when the solution turns from blue to light green. 11. Record the result of the titres. 7. 11 Alcohol titration calculations: **(Refer to journal for titration calculations) 8. 0- Results and Data Analysis: 8. 1- graph 1 – PH over time:The above graph displays the pH obtained for each wine over the 5 trials conducted. Initially before adding the clearing agent s, the wine was tested to be at pH 4 as indicated at ‘trial 0’. After the clearing agents were added the pH remained at 4 however the Isinglass fined wine increased to pH 4. 3. Standard wine must be kept at a pH range between 3. 2 and 4. 1 therefore anything over 4. 1 raises alarms and action must be taken to lower the pH using acidic substances. Ultimately 1g of Tartaric acid was added to all wines during trial 1 and subsequently resulted in the decrease in pH observed from trial 1-3.Trial 3 was the point at which the pH of all four wines was recorded at a constant 3. 2 indicating that the Tartaric acid was successful at lowering the pH by almost 1 for all four wines. From trial 3-5 the pH of all the wines is seen to fluctuate once again this is due to the fact that the effects of the tartaric acid have ceased therefore the pH system increases and decreases accordingly as it tries to find a new state of equilibrium. This trend can be related to Le Chateliers principle which states that â€Å"If a system at equilibrium is disturbed, then the system adjusts itself so as to minimise the disturbance.At the end of trial 5 all four wines fell between a stable pH range however following the low pH of trial 3, Isinglass fluctuated to pH 3. 7 as seen in trial 5. This raises the possibility that the pH of Isinglass may have continued to raise. 8. 2- Graph 2 – Alcohol %v/v over time The above is the comparison of alcohol content for all the wines over the 5 trials conducted. All wines clearly tend to show a percentage of alcohol between 4-6% throughout the trials with the overall average being 4. 2%. At the end of trial 5, all four wines recorded a stable 4%v/v alcohol however this is unusual considering that wines are typically 7-14%v/v.The 11%v/v recorded for the control at trial 3 is believed to be due to error as there is no justifiable reason for such an instantaneously high fluctuation. It is seen that all wines containing fining agents record ed an alcohol level that was similar to each other; this was ultimately expected as fining agents do not typically affect alcohol level. These readings from the vinometer can ultimately be relied upon as alternative alcohol testing through the more accurate titration method showed that the alcohol level was at approximately 5% which is the most common value presented throughout the vinometer testing. . 3- Graph 3- Sediment level over time Displayed above is the graphical analysis of the sediment level recorded over time for each wine. There is a clear indication that the wine finned with Bentonite produced the most lees followed by the Gelatine/Kieselsol and then the Isinglass which accumulated the least amount of lees out of the three clearing agents. Overall however, the control (wine without fining agent) showed a very limited accumulation of sediment therefore indicating that sedimentation rate is slower without a presence of a clearing agent.Interestingly the Bentonite also rec orded instant sedimentation of 1. 5cm for the first trial which is more than twice as much as that of the Gelatine/Kieselsol and three times more than the Isinglass and control. The control also displayed the slowest rate of accumulation of lees with a 0. 1cm increase occurring once every 2 trials. Some results show a drop in sediment level; this should ultimately be ignored as the measurement of sediment encompasses an uncertainty of (+- 0. 5cm) therefore the recorded drop in sediment may just be an indication of no change. . 4 – Graph 4- Difference in sediment level over time: The above graph has been constructed to aid in the interpretation of the previous (Graph 3). This displays the difference in sediment level for each wine from trial to trial. Ultimately the total increase of sediment for Bentonite over the 5 trials was +1. 9cm (assuming that the –0. 1 is treated as a no increase rather than a decrease). The Kieselsol/Gelatine recorded a total increase of +1. 6c m. Isinglass obtained a total of +0. 8 and the Control showed a +0. 7 total increase over the 5 trial periods. 8. – Graph 5- Turbidity (NTU) over time: The above ‘turbidity over time’ graph ultimately displays the extent at which the wines were cleared. The results obtained for turbidity show the same trend that is seen in the sediment accumulation graph in terms of the fining agent performance. Bentonite was most effective at clearing the wine, bringing the turbidity down from 600 to 250NTU followed by Kieselsol/Gelatine which was successful in a turbidity reduction from 600 to 300 NTU. Isinglass again presents itself as the weakest clearing agent only clearing the wine from 600 to approximately 450NTU.The Control indicated only a slight decrease in turbidity of 50NTU in total. Notice that major reduction in turbidity for all four wines ceases from trial 3 onwards, this trend was also recorded in the sediment graph. Another trend that is seen in this graph and t he sediment accumulation graph alike is that Bentonite again appears to have the greatest initial impact out of all the fining agents. *The lack in results for trial 1 is due to not having the turbidity tube available at that time. 8. 6- Graph 6- Electric Conductivity over time:Electrical conductivity was tested purely because it can give an indication of TDS through a conversion factor. Again what is immediately noticed is that on the 5th trials, Bentonite had the greatest overall drop in EC/TDS. Followed by Kieselsol/Gelatine then Isinglass. The control showed the least overall reduction of EC/TDS and this is a trend seen in the previous Turbidity and Sediment graphs. (Refer to Journal for raw data tables and the conversion from EC to TDS) 9. 0- Discussion: Through the analysis of the results obtained, many justifications can be drawn as to the fining agent that had the greatest effect on clarification.By graphing the primary trends in turbidity and sediment level, the initial hyp othesis was ultimately rendered incorrect to some extent. It was hypothesised that the Kieselsol/Gelatine would have the greatest fining ability due to the agent being composed of both positive and negative charges. This however was not the case when the results were analysed. Ultimately the Bentonite was recorded to have the greatest fining ability followed by the Kieselsol/Gelatine and then the Isinglass which as predicted, presented itself as the weakest of the three fining agents.The Bentonite agent visibly resulted in the most sediment accumulation, recording a total of 1. 8cm of lees and a turbidity reduction of 350NTU in total. Interestingly, Bentonite also exhibited a very fast rate of efficiency with an accumulation of 1. 5cm of sediment in the very first trial (Graph 3). This was more than double the sediment level of Kieselsol/Gelatine and triple the amount recorded for Isinglass. Similar trends in rapid efficiency are seen in (Graph 5) where Bentonite is noticed to reduc e turbidity by half in the very first trial.These superior clearing abilities stem from the complex molecular composition of the substance. Bentonite is comprised of a multitude of small silicate platelets that are separated by a layer of water molecules (Zoecklein, B. 1988). During the initial Bentonite hydration performed before adding it to the wine, these platelets repel each other and subsequently pop apart. As this occurs, the platelets rearrange and immense swelling takes place which results in an enormous surface area (refer to appendix figure 2).It is this enlarged surface area that grants Bentonite the ability to absorb a greater amount of suspended matter. Further evidence shows that there are more molecular properties that can justify the dominant fining capabilities of the Bentonite agent. Foremost, Bentonite is renowned for its high cation exchange capacity (binding ability) (Catarino, S. 2007). Typically there is a tremendously fast reaction time between positively ch arged protein particulates and the negatively charge Bentonite.It is common for three-quarters of proteins to react with Bentonite within the first minute of contact (Zoecklein, B. 1988). Protein contents from an initial 50-100mg/L can be cleared to less than 10mg/L in most circumstances therefore this high clearing capacity is another reason why such elevated amounts of sediment deposits were recorded during testing. Another aspect to consider is the relationship between ethanol concentration and Bentonite. Scientific research has suggested that there is a proportional relationship between ethanol concentration and the efficiency of the Bentonite fining.This is due primarily to the fact that ethanol separates the silicate layers within the structure therefore allowing larger particles to adsorb to the surface (Harberton, J. 2009). Basically out of the three fining agents, Bentonite is the only one that exhibits this relationship with alcohol thus its flocculation ability is advanta ged when placed in an ethanol rich solution such as the wine. What can further be associated with the Bentonite’s vast flocculation ability is that the agent is not exclusively of a negative charge.Interestingly, the molecular platelet edges are comprised of a slight positive charge (AMCOL, 2005) (refer to Appendix figure 4). This gives the Bentonite an additional aptitude to bind to some negatively charged particles therefore providing a wider range of clearing potential. When looking back on the results obtained, the hypothesis was validated to the extent that the wine without a fining agent (the control) showed least efficiency in clarification. As seen in Graph 3 (sediment level over time), the control not only accumulated very small amounts of sediment but also did this at a very slow rate.An increase of 0. 1cm is noticed only once every two trials whereas the fining agents show a substantial increase nearly every single trial. The same goes for the turbidity reduction ( Graph 5) where the control is seen to take approximately three trial periods to attain a decrease of a mere 50NTU. Although the control showed signs of clearing due to gravity, it is substantially slower than that of the fining agents. A scientific principle set out by physicist George Stokes in 1851, aids in the conceptualisation of why the fining agents are more efficient in sedimentation.Stokes’ law states that the rate of sedimentation of a spherical particle is directly proportional to the difference in density of the particle and the liquid, the acceleration due to gravity and the radius of the particle (Stoyanov, P. 1980). By the application of this law, it stands to reason that a fining agent causes swifter sedimentation as it increases the radius of the particles through electrostatic binding and this in turn causes the particles to have a greater density ultimately increasing the rate of clarification It was also initially hypothesised that Isinglass would perform l east efficiently out of the three fining agent.This was confirmed through the data analysis which showed that Isinglass produced three time less sediment than Bentonite and only reduced turbidity by 150NTU unlike Kieselsol/Gelatine which reduced turbidity by 300NTU and Bentonite which resulted in a 350NTU reduction. Isinglass was ultimately not anticipated to have great fining abilities due to its gentle nature which renders it more suitable for wine polishing rather than heavy clearing (Chorniak, J. 2007). According to external scientific sources, the overall fining rate of Isinglass stands at a low 0. 2 – 0. 1g/L-1 therefore adding justification as to the low sediment yields recorded for Isinglass in this chemistry experiment. There is however another biochemical issue that may have attributed to the underperformance of the Isinglass agent. Collagens such as isinglass are typically dependant on temperature for chemical stability. At high temperature most collagens begin to decompose on a molecular scale. Isinglass starts to denature at a relatively low temperature of approximately 10 °C.This denaturing process results in a reduction of molecular weight which consequently weakens the fining ability (Hornsey, I. 2007). Throughout the course of this experiment, the wines tested were exposed to temperature of over 18 °C hence leading to the presumption that this may have contributed to isinglass’ lack in performance. When analysing the data to a greater extent, there was a very crucial trend that was established which may have affected the performance of all the clearing agents. pH is ultimately seen to have an inversely proportion relationship with the binding ability of the fining agents.As pH increases, the strength of the electrostatic attract between the fining agent and particles is subsequently decreased. This principle is extensively evident for all three fining agents tested in this experiment. Notice that after trial 3 (graph 5) the t urbidity no longer shows improvements for both Bentonite and Isinglass and only exhibits a minimal improvement for Kieselsol/Gelatine. This is also notice for the sediment level (graph 3) which shows only very slight increases in sediment accumulation after trial 3.This reduced performance after trial 3 may be due to the fact that the pH of all wines began to fluctuate from trial 3 onwards (refer to graph 1). Overall it is seen that the clearing agents performed best when the pH was reducing during trial 1 and 2 and started to perform poorly when the pH began to fluctuate from trial 3. To comprehend this phenomenon it is important to understand the concept of the Isoelectric point (pl). Basically all proteins or other suspended particles have a certain pH at which the particles carry no net charge.If the pH of a solution is too high or near the isoelectric point, the particulates will not be sufficient in electrostatic attraction because at a high pH, the molecules carry an equal nu mber of positive and negative charges resulting in neutralisation (Zoecklein, B. 1988). This is also true for the fining agents which lose electrostatic charge when there is even a slight increase in pH. Recent studies that tested the net charge of isinglass in different pH medium show that even a small increase of 0. 5 pH resulted in the reduction of approximately half the net charge of the isinglass agent (Ward, I. 000) (refer to appendix figure 3). This evidence adds credibility to the justification that the rise in pH may have indeed contributed to the trend noticed in all the fining agents. Alternatively however there is the possibility that the fining agents simply reached their capacity and began decreasing in efficiency after trial 3 indicating that more fining must be added. Overall through the in-depth interpretation of the data; the performance of the fining agents can be justified and links can be draws as to the agent that performed the best and worst (the Bentonite and Isinglass respectively).However although this experiment was successful in giving reasonably good results it is undoubtabley encompassed by multitudinous amounts of human error and uncertainty that may render it flawed to some extent. The major flaw to this experiment is that sediment was not siphoned after every trial. The group initially chose not to siphon the lees so that results could be easily recorded. However what was not realised is that every time the wine was poured out for testing, the deposit of sediment was resuspended into the wine therefore may have resulted in highly inaccurate results especially for turbidity.Another associated human error is that members from the group at some stages touched the wine with bare hands that were not disinfected especially during Vinometer testing. This holds a great risk that the wine may have become contaminated thus predisposed to bacterial manifestation which would render the experiment invalid. Gloves were only used after the 2n d trial period once the group noticed the risk of contamination. Other possible sources of contamination include the fact that some equipment were not washed with sodium metabisulphite before making contact with the wine, this again posses high risk of bacterial growth.At one stage there was speculation whether the wine had indeed contracted a bacterial strain. This is due to the hazy/cloudy appearance of the wine despite the extensive fining that was performed. Although turbidity was slightly reduced by the fining agent, the wine still seemed awfully turbid. This could be a sign of a bacterial colony which causes a liquid to appear murky and is ultimately untreatable by the fining process. When expert opinion was consulted about the wine, it was concluded that the turbid appearance was not due to bacteria.If the wine had been infected, it would have had a very ‘off’ taste which was not indicated during the weekly wine tasting. What must be noted is that because the win e in this group was created with oranges, it will never have a very clear appearance due to the thickness and dark colouration of the orange contents. Common wines made from grapes are naturally very clear due to the transparency of the grape juice by nature. It was therefore presumed that the turbid look of the wine was due to the natural composition of the oranges it was made from.If this experiment was to be performed again, many improvements must be made to ensure more accurate and valid results. It is recommended that more emphasis must be placed into contamination control and management during the winemaking and wine testing period. This will ensure no foreign material spoil the validity of the experiment. Also there was major uncertainty in the equipment used. Firstly the ruler used to measure sediment carries a +/- 0. 5cm uncertainty which is major especially when measuring something so small such as sedimentation deposit.Maybe a more accurate measuring tool with a smaller s cale can be used in the future for the lees measurement. Furthermore all testing including pH, Turbidity, Vinometer etc were only done once every trial period whereas it is advisable to always test a sample 3 times in a row to ensure consistency in the results. This was not done in this experiment as time restraints did not allow for repeated testing. If these simple improvements can be implemented for future testing, the results will be more accurate which will in turn provide more credibility to the findings. 10- Conclusion:The process of wine making and testing was a long and arduous task that involved many procedures. Although there were some minor flaws involved with the testing, the experiment was considered an overall success. The aim from the start was to see which flocculation agent would have the greatest effect on wine clarification and through extensive testing the results clearly indicated the superior fining agent. The Bentonite was undoubtabley the most powerful flocc ulation chemical and resulted in the greatest reduction in turbidity and also the greatest increase in sedimentation.The trends and patterns in the data were evaluated and scientific justifications were made as to why each fining agent performed to the extent that was witnessed. Ultimately relationships between variables were established as explanations that coincide with the performance of the fining agents. Wine pH, alcohol level and temperature are concluded to have a drastic effect on the flocculation abilities of the fining agents. These variables must be monitored and adjusted accordingly as the efficiency of the clearing agents are found to be very dependent upon their values.For future reference, pH is seen to affect the electrostatic bonding abilities of the substances, alcohol levels have a proportional relationship to the fining abilities of Bentonite and temperature (either to low or to high) affects the efficiency of the chemical fining process especially that of the Is inglass. With this in mind it can be concluded that the fining agents did help in the clarification of the wine however were affected by many variables that must be taken into account if this experiment was to be performed in future.

This is one of the main reasons why Bentonite is such a powerful flocculation agent. From left to right; Water molecules between the silicate layers, Layers then pop apart during hydration, the platelets rearrange and swelling takes place, once rearrangement has occurred the surface area is greater than before hydration.

Because Bentonite has slightly positive charged edges it is advantaged in its fining ability.
