Vitamin C Content of Apple Juice :: essays research papers

Vitamin C Content of Apple Juice Introduction Complete lack of ascorbic acid (a.k.a Vitamin C) in the diets of humans and other primates leads to a classic nutritional disease, scurvy. This disease was widespread in Europe during the fifteenth and sixteenth centuries, but it is rare today. Ascorbic acid is widely distributed in nature, but it occurs in extremely high concentrations in citrus and green plants such as green peppers and spinach. Ascorbic acid can be synthesized by all plants and animals, with the exception of humans, other primates, and guinea pigs. Therefore, vitamin C must be present in our dietary substances.   Ã‚  Ã‚  Ã‚  Ã‚  The fundamental role of ascorbic acid in metabolic processes is not very well understood. There is some evidence that it may be involved in metabolic hydroxylation reactions of tyrosine, proline, and some steroid hormones, and in the cleavage-oxidation of homogentisic acid. Its function in these metabolic processes appears to be related to the ability of vitamin C to act as a reducing agent.   Ã‚  Ã‚  Ã‚  Ã‚  The adult Recommended Daily Allowance f vitamin C is 70 mg per day. Some scientists and physicians have suggested doses up to 1 to 3 grams per day in order to help resist the common cold. Deficiency of vitamin C results in swollen joint, abnormal development and maintenance of tissue structures, and eventually scurvy.   Ã‚  Ã‚  Ã‚  Ã‚  Determination of vitamin C in biological fluids such as bolld and urine is difficult because only small amounts of the vitamin are present and many interfering reducing agents are present. Substances containing sulfhydryl groups, sulfite, and thisosufate are common in biological fluids and react with DCIP, but much more slowly than ascorbic acid. The interference by sulfhydryl is often minimized by the addition of p-cholormercuribenzoic acid. Materials and Supplies Apple Juice Metaphosphoric acid/ Acetic acid solution 4% Unknown ascorbic acid in metaphosphoric acid/acetic acid solution, .5mg/ml 2,6 dicholorphenolindophenol solution in water Ascorbic acid oxidase, lyophilized water Experimental Procedure Standard Ascorbic Acid Solution Fill a microburet with DCIP solution. Using a pipet, transfer 1.0 ml of the ascorbic acid standard solution to a 50 ml Erlenmeyer flask containing 5 ml of 4% metaphosphoric acid solution. Read and record the initial reading on the buret. Titrate by rapid, dropwise addition of DCIP from the buret while mixing the contents of the flask. Add DCIP solution until a distinct rose-pink color persists for 15-20 seconds. Record the final reading on the buret. Repeat this procedure twice more, each time with a fresh 1.

Sophocles’ antigone

Oedipus meets all the criteria of a tragic hero.   He is of noble birth with a character that is consistent throughout as a truth-seeker, always in quest of knowledge, and a riddle-solver wanting to be a savior of people; yet as every other person, he had his flaws, which reversed his prosperity.His intelligence and stateliness is worthy of that of a king, so his doom fills the readers with pity and fear, which is the essence of a tragedy.Though Oedipus realizes that fate had a hand in his doom, he knew he had his own flaws.A woman can also be a tragic hero so long as she meets the criteria set for a tragic hero, and Antigone meets all the criteria. Yet I consider Oedipus to be the best tragic hero here, he being glorious and his fall, dramatic.To go by Aristotle’s view, Antigone, Oedipus and Creon, all   meet the criteria of   being tragic heroes in that all of them face disastrous consequences because of certain fundamental flaws common to humanity.(3)Antigone strongly felt Creon should not interfere in matters relating to religion, andleaving the dead unburied was against the divine law.   She defies Creon and does notever regret it even in the face of death. Thus her remark, â€Å"I do not think your edicts strong enough to overrule the unwritten unalterable laws of God and heaven, you being only a man.†Creon on the other hand respects the rules of the state, and though he could have changed them, if he so chose, remains adamant that Polynice, her brother, be left to rot.   Ismene does not act emotionally.   She thinks twice about dying for the dead.Antigone’s views clashed with that of the others in that she failed to see the impact of her action on those around her, for instance Haemon.(4)The Greek view is that a tragic hero should ideally be a king so that his people also experience his fall.   He should be venerable but imperfect so that the audience may associate themselves with him.As great as the hero is, they feel his fall should be as great too, a calamity worthy of their hero.  Ã‚   But modern-day hero is not necessarily of royal birth. He can rise to glory by contributing positively to the society or the world at large, and unlike the tragic hero, who often dies or survives only to suffer, may even be victorious, and his flaws are not fatal.To quote Duane Lowry, a member of the American Political Historians Association, an American hero is â€Å"someone who embodies popular values and is the driving force behind an important social, political, or scientific change or transformation that lifts the spirit of America and betters the situation of the country.†

Politics of George Clooney, Actor and Liberal Activist

American actor George Clooney is a liberal, a strong supporter of liberal causes and charities, and an outspoken critic of conservative politics and warmongering. Clooney supported John Kerry for President in 2004; Barack Obama in 2008 and 2012, and Hilary Clinton in 2016. Among other causes, he actively supports gay rights. Im a liberal. Im confused when that became a bad word. Its interesting. I think what happened over a period of time, probably in the late 80s when it became sort of a political tool.... [T]he liberal movement morally, you know, has stood on the right side of an awful lot of issues. We thought that blacks should be allowed to sit at the front of the bus and women should be able to vote, McCarthy was wrong, Vietnam was a mistake.  George Clooney to CNNs Larry King on February 16, 2006. Actor, Director, Producer George Clooney is best-known as having been a television and film actor since early 1980s, and as a director and film producer since 2002s Confessions of a Dangerous Mind. Most Americans first noticed him as the handsome Dr. Doug Ross on the popular television program ER from 1994 to 1999. Clooney regularly appeared in five other television shows prior to ER. Clooneys acting credits range from the goofy Return of the Killer Tomatoes (1988) to the seriocomic O Brother Where Art Thou, the Coen brothers 2000 take on Homers The Odyssey. His writing, producing, and directing credits include political-commentary films such as Syriana (2005) and The American (2010), as well as historically-themed films such as The Monuments Men (2014) and Good Night, and Good Luck (2006). The Clooney Family George Clooney was born in 1961 near Lexington, Kentucky to Nick Clooney, a regional newscaster and well-liked TV personality, and Nina Warren Clooney, local city council member, and former Kentucky beauty queen. Hes also the nephew of the singer Rosemary Clooney and cousin of actor Miguel Ferrer. One 2003 article dubs the Clooney clan the Kennedys of Kentucky for their formidable liberal influence in the conservative northern part of that state. By all reports, the Clooneys are a close-knit, Irish-Catholic family, and George is fiercely loyal to his father. When Nick Clooney ran for Congress in 2004, George raised over $600,000 from fellow celebrity-activists for his fathers unsuccessful campaign and made personal appearances on behalf of his father. Charity Causes In the charity world, Clooney is known for his work with numerous disaster relief efforts, including America: A Tribute to Heroes in 2001 for victims of 9/11; Tsunami Aid: A Concert of Hope, to benefit victims of the late-2004 Indian Ocean tsunami; and the Hope for Haiti Now for the victims of the 2010 earthquake. Clooney donated $1 million in September 2005 to the United Way Hurricane Katrina Response Fund to help out the victims of the hurricane. Clooney is a member of the United Way Board of Trustees. Said Clooney when he made the donation, Today our neighbors need food, shelter, and health care, but the very near future is when the difficult part of rebuilding lives and homes and cities starts. Were all in this one together. In March 2006, Clooney donated his Oscar gift-bag (Value: about $100,000) to the United Way, to be auctioned off to benefit that humanitarian organizations programs. Preventing Mass Atrocities Clooney has also contributed money and time to the recognition, prevention, and cessation of genocides and mass atrocities. He was instrumental in the creation of Journey to Darfur, a program on the ongoing conflict in Darfur; the recognition of the Armenian Genocide; the Satellite Sentinel Project reporting on the civil war between Sudan and South Sudan; and the Aurora Prize, which awards people who risk their lives to present genocides and atrocities. In 2006, Clooneys longtime liberal activism and unabashed political views also rose to headline-attracting public prominence. After a 5-day visit to Darfur, Clooney spoke out against genocide in that country and urged greater US and NATO involvement. In September 2006, Clooney testified before the UN Security Council, urging that UN peacekeepers enter Darfur. Clooney and the Conservative Media Clooney has been the focus of attacks from conservative media outlets. In September 2001, Clooney was a primary organizer on a telethon to raise money for victims of 9/11. The program, America: A Tribute to Heroes raised US $129 million which was donated to The United Way. Conservative political commentator Bill OReilly took Clooney and his associates to task for not appearing on The OReilly Factor program to respond to scattered news reports that the money was not, in fact, going to the victims. Infuriated, Clooney responded in an angry letter to OReilly on November 6, 2001, in which he scolded, The fund is not only the most successful single fundraiser ever, it is doing exactly what it is designed to do. Responsibly. The money is going out to the right people... In 2014, the British tabloid The Daily Mail reported that the family of his then-fiancee, Amal Alamuddin, opposed their marriage on religious grounds, saying that some of her relatives had joked about killing the bride if she disobeyed her parents. Clooney wrote an open letter in the USA Today calling the paper a laughable tabloid that crossed into the arena of inciting violence. A Few Political Films Over his career, Clooney has appeared in and had some creative control over the production of several films with political content. Here are a few of the best known. Three Kings (1999)—At the Gulf Wars end, four US soldiers come across a potential jackpot: a rolled up treasure map to Saddam Husseins stashes of confiscated gold hidden bewteen the buttocks of a captured soldier. While pursuing selfish gain, the men collide with Iraqi civilians and experience a different side of the war.Confessions of a Dangerous Mind  (2002)—Based on the life of Chuck Barris, who claimed dual careers as loony game-show host and CIA operative for the US government. Also directed by Clooney.Good Night, and Good Luck (2005)—Taking place during the early days of broadcast journalism in 1950s America, this film chronicles the real-life conflict between newsman Edward R. Murrow and Senator Joseph McCarthy and his House Un-American Activities Committee. In a political climate of fear and reprisal, the CBS news crew persists. McCarthy is brought before the Senate and made powerless as his lies and bullying tactics are finally uncovered. Clooney was n ominated for a Best Director Oscar for this film.Syriana (2005)—In this political thriller that unfolds against the intrigue of the global oil industry, Clooney plays the role of career CIA operative who disturbing truths about the work to which he has devoted his life. He won the 2006 Best Supporting Oscar and a Golden Globe for this role.The Ides of March (2011)—Clooney directed and co-wrote the screenplay for this take on modern-day dirty politics,Money Monster (2016)—A financial TV hose and his producer are taken hostage by an irate investor who is convinced there is a conspiracy driving fluctuations in global high tech markets. Summing Up Liberalism When asked in 2005 by the German magazine Brigitte, why conservatives continually vilify liberals, Clooney succinctly summed up liberalism.... Its quite amazing that liberal nowadays has become a swear word as in the history of our country it always meant to be on the side of justice. It started with the witchhunt in Salem, the conservatives point of view was: Burn them at the stake, and the liberals point of view was: There are no witches. And thats how it continued with the civil rights movement and womens suffrage. The liberals were always right in the end. Sources: Carr. 2005. A ringside seat for Murrow versus McCarthy.
