Enzyme Activity Lab essays
Enzyme Activity Lab essays In the investigation, a catalase and an enzyme whose occurrence is widespread in cells, particularly in liver cells was used. The catalase from a fresh calf liver was used. In this lab, catalase and H2O2 were combined under different substrate concentrations 6%, 4%, 2%, 1% and 0.5% with two drops of diluted detergent. Measurements of the volume of O2 released during these reactions were recorded to determine the rate of reaction. The reaction rates of the enzyme in 6%, 4%, 2%, 1% and 0.5% concentration of Hydrogen Peroxide were 1.56 mL/s, 1.54 mL/s, 1.01 mL/s, 0.56 mL/s and 0.23 mL/s respectively. When the liver was added in distilled water and detergent it did not react. It was observed in the lab that the optimum concentration for enzyme activity is when the substrate concentration is 6%. After the optimum substrate concentration is reached, the reaction rate levels off because as the substrate concentration increases the active sites get occupied with the substrate and there are not enough active sites to break down all of the Hydrogen Peroxide molecules. At this point virtually all the active sites are occupied so the active sites are saturated with Hydrogen Peroxide. Increasing the Hydrogen Peroxide Concentration after the point of saturation has been reached will not cause the rate of reaction to go up any more. When the substrate concentration is lower the reaction rate is slower. Enzymes function as biological catalysts, substances that speed up chemical reactions. Chemically, enzymes are proteins and their three-dimensional shape is important to their catalytic activity. Enzymes are highly specific in terms of the reactions they will catalyse. This means that literally hundreds of different enzymes are required to catalyse the many different reactions which take place in your body each day. The breakdown of hydrogen peroxide, H2O2, is speeded up by catalase. Catalase functions to speed the breakdown of peroxides which ...

Why the perfect resume wont get you the job
Why the perfect resume wont get you the job Weââ¬â¢ve all been there- the seemingly endless hours of toil, the struggle and intense focus, the attention to every detail both large and small, the tweaks and rewrites based on multiple rounds of feedback and criticism from everyone who was ever important to us in our livesâ⬠¦until as close of a version of perfection is achieved. What are we talking about?Yes, we can only be talking about one thing- itââ¬â¢s your resume, and we all know how valuable a document it can be. In short, your resume is your initial handshake, your smile, your first impression to potential employers and hiring managers- and you really want to make it count.According to a recent article in Psychology Today, the power of first impressions is undeniable and ââ¬Å"first impressions matter, for good and badâ⬠(Google ââ¬Å"the halo effectâ⬠if youââ¬â¢re curious and want to learn more about the lasting power of first impressions).We also know that the competition to get a new job is in tense, and some fields are even tougher than others, so the time and effort spent on perfecting your resume is time well spent!Howeverâ⬠¦if you think your resume will be your ââ¬Å"golden ticketâ⬠to your next job, think again. While itââ¬â¢s true that an impressive resume can help open doors and put you in the running for new job opportunities, even an absolutely perfect resume wonââ¬â¢t automatically guarantee you the job.You resume may open doors, but it likely wonââ¬â¢t get you the keys, if you get our meaning- itââ¬â¢s a document designed to grab the attention of hiring managers and potential employers, but itââ¬â¢s up to you to seal the deal. Remember, theyââ¬â¢re looking to hire a person, not a piece of paper, so more than just your resume will be under review during the hiring process. While itââ¬â¢s true that your resume can- and hopefully will- get them interested, theyââ¬â¢ll want to know if you actually live up to the initial impression they got from reading about you.Furthermore, the competition youââ¬â¢ll face is just as hungry for the jobs youââ¬â¢re going after and you better believe that many of their resumes will also be perfect too. So, in a universe of impeccable resumes, the thing that separates the winners from everyone else in the job-hunting game is what they bring to the table after their resumes makes the initial first impression.So, if youââ¬â¢re lucky enough to get to move forward in the hiring process, perhaps to a phone call or video conference call, or even a face-to-face interview, youââ¬â¢re going to have to continue the job that your resume started. This means looking your best, demonstrating impeccable communication skills, instilling confidence that your skill set, experience, and innate abilities match well with the job, and giving the impression that youââ¬â¢d be a great person to work alongside everyday and a valuable addition to their team. Youââ¬â¢ll also need to make a convincing case why youââ¬â¢re a better choice than all the other people with perfect resumes that youââ¬â¢ll be competing against.Hereââ¬â¢s the bottom line: itââ¬â¢s definitely worth your time and effort to craft a stellar resume, but if youââ¬â¢re really serious about landing that job opportunity you have in your sights you need to pay just as much attention to making sure that you make as good of an impression as your resume does. Donââ¬â¢t forget- your resume will get your foot in the door, but itââ¬â¢s up to the rest of you to keep it there!

Property Land Law Essay Example | Topics and Well Written Essays - 1000 words
Property Land Law - Essay Example Felix S. Cohen suggests that property is about relationships between people. An individual's proprietary interest will depend on his ability, as accorded by law, to dispose of his property as he sees fit and prevent others from enjoying or utilizing it. Proprietary interests can be fragmented among a number of individuals or groups over different levels, making the ability to exclude others more difficult and confusing, oftentimes leading to property disputes.In Western Australia, such problems become more confusing because of two existing systems of land ownership. The case of the Hillside and Coventry properties is an example where Frederick, owner of the two properties with fee simple interests, mortgaged and consequently sold to Marjorie, Lucille, and Bernie. This left the parties with competing interests, thus calling for the need to determine whose interest is greater and what each party can do to create an interest in the aforementioned properties. According to the Old System, upon which Hillside is initially registered under, Marjorie, upon entering into a contract with Frederick possess an equitable interest in the property. With regard to Bernie, his interest depends on whether there was a conveyance of deeds and the legal interests were transferred to Lucille. Lucilleââ¬â¢s interest, however, as second mortgagee is quite interesting.Both Lucille and Marjorieââ¬â¢s interests are subject to the equity of redemption.... Hence, there cannot be two legal mortgages over a single property. This, however, does not apply because in Lucille's case, although her mortgage happened subsequent to Marjorie's mortgage, the legal interest was not transferred to Marjorie because Frederick kept the deeds and gave them to Lucille. In this sense, Lucille has the legal interest in the property. However, it is important to determine whether there has been a conveyance of properties. The case only mentioned Frederick giving the deeds of the property to Lucille. If such can be considered a conveyance of the deeds, she possesses the legal interest. On the contrary, if there was no conveyance of deeds, her interest remains equitable. Both Lucille and Marjorie's interests are subject to the equity of redemption3. Thus, although a transfer was made based on the Old System, Frederick still retains certain interests in the property, including the right to redeem it, provided that he complies with his obligations. With regard to Bernie, his interest depends on whether there was a conveyance of deeds and the legal interests were transferred to Lucille. Assuming that Frederick's legal interests were transferred to Lucille by virtue of the mortgage, Bernie possesses only an equitable interest in Hillside based on the equity of redemption, which Frederick retained upon the mortgage. This is because at the time the sale took place, Frederick did not have a legal interest in the property to sell to Bernie by virtue of the mortgage. Hence, Bernie will only possess a legal interest after the mortgage is paid off and redeems his rights from Lucille. Between Lucille and Marjorie, Lucille's interest takes priority because she conducted the legal mortgage, hence possessing a legal interest. Between Lucille and Bernie,

EVALUATION Assignment Example | Topics and Well Written Essays - 250 words
EVALUATION - Assignment Example Firstly, the game leads to participants pushing their bodies to the limits. Secondly, they use drugs to gain extra strength and outdo their competitors. Lastly, the participants contact injuries such as concussions (Arkinstall, p, 2). Participants in the game of football harm their bodies by pushing it to the limit. The coaches in this game do not consider the fatigue generated by players in consecutive matches. Players end up straining their muscles due to restless playing in different matches in different tournaments. The existence of a super player in the team leads to overworking of the player to retain the title or class of the team(Arkinstall, pp, 2-3). Football as a sport is also a competition. For players to maintain their standards in the world of football, they end up using hardcore drugs such as cocaine and bang. An example of such players is Diego Maradona, who has become an addict of drugs because of football. In the world of football, many upcoming young talents force the elder players to engage in drugs to maintain their positions (Arkinstall, pp, 2-4). Due to increased competition, players get rough in the field to earn a position in their teams. Due to this, they develop injuries such as concussions. The injuries keep on recurring that risk the life of players. For these reasons, strict measures and rules should be put in place (Arkinstall, pp,

Pornography Should Be Free
Pornography Should Be Free from Government Control Essay Whether one feels strongly about the viewing, making and distribution of pornography by consenting adults, one cannot argue that sex isnââ¬â¢t everywhere. Evident in videos, movies, pictures, and advertisements, itââ¬â¢s a fact that sex sells. Who is to say that because pornography can be viewed easily in many ways, that itââ¬â¢s not a bad thing? Yet in the discourse of pornography as a whole, where does morality and money come into play? To whatever extent pornography is considered immoral; everyone should be entitled their own intellectual freedom. The government has made some steps in order to limit the spread of pornography, yet it is apparent that little can be done to ultimately affect it. In 1968, the Supreme Court case of Ginsberg v. New York held that the government can legally prohibit children from accessing certain types of sexually explicit material, the same material that canââ¬â¢t be banned for adults. Even though the Supreme Court ruled that a minor does not have the constitutional right to the same content as an adult, the task of restricting content on the internet is shaky, due to the difficulty of distinguishing adults from children. In 1973, a following Supreme Court case, Miller v. California, established the phenomenon of ââ¬Å"variable toleranceâ⬠. Leaving a variable tolerance existing for explicit material, the Supreme Court allowed communities to decide what was indecent or obscene. Different levels of tolerance of pornography from community to community could be a successful system if in fact, pornography distribution can be limited community by community. Because people are mobile and the internet is boundary-free, the government cannot effectively restrict its availability to everyone (and possibly to anyone). Another notable court case involved with pornography was the 1982 case, Ferber v. New York. This case basically addressed all material showing a ââ¬Ësexual performanceââ¬â¢ by a child under the age of 16, as obscene. It defined a sexual performance as, ââ¬Å"actual or simulated sexual intercourse, deviate sexual intercourse, sexual bestiality, masturbation, sado-masochistic abuse, or lewd exhibition of the genitals.â⬠Itââ¬â¢s a federal offense to knowingly receive child pornography. According to the International Federation of Library Associations and Institutions, ââ¬Å"intellectual freedom is the right of every individual both to hold and express opinions and to seek and receive information.â⬠The freedom of an adult to view pornography involving other adults is not really recognized as a recreational activity, mainly because it is scorned upon in many religions. Even the majority of parental figures in the world seem to demonize pornography when raising their youth. Yet no one really steps back and asks, why exactly is pornography immoral? One of the major arguments towards pornography being immoral is that in many pornographic depictions, people (usually women) seem to be victimized for a viewerââ¬â¢s pleasure. The only difference between an African American woman playing a role as a slave in the civil war era, an African American woman posing in shackle-like bracelets in a skinny jean advertisement, and an African American woman in a pornographic film, is that each different role requires certain talents and understandings that come together in order to entertain an audience. Immoral or not, pornographic material is nothing more than another way to make money. Itââ¬â¢s seen or referenced to in many advertisements, and itââ¬â¢s difficult to find an ââ¬Å"Râ⬠rated movie with out at least one nudity scene. Once again, sex sells. Wherever there is demand, there will be supply, and the statistics behind internet pornography are somewhat staggering. According to Information Science professor and researcher, Paul F Burton, ââ¬Å"47% of the 11,000 most popular searches on the Internet are targeted towards pornography.â⬠The money aspect of pornography is almost incomprehensible. There are over 1.5 million internet users viewing pornography every minute. From that audience, $3,075.64 is spent on pornography each second, and every 40 minutes, a new pornographic video is made in the United States alone. The market for pornography is huge.

Flannery O8217Conner and Grotesque Characters :: essays papers
Flannery O8217Conner and Grotesque Characters Flannery Oââ¬â¢Conner and Grotesque Characters One of the most interesting characteristics of Flannery Oââ¬â¢Conners writing is her penchant for creating characters with physical or mental disabilities. Though critics sometimes unkindly labeled her a maker of grotesques, this talent for creating flawed characters served her well. In fact, though termed grotesque, Oââ¬â¢Conners use of vivid visual imagery when describing people and their shortcomings is the technique that makes her work most realistic. Oââ¬â¢Conner herself once remarked that ââ¬Å"anything that comes out of the South is going to be called grotesque by the Northern reader, unless it is grotesque, in which case it will be called realistic.â⬠In Oââ¬â¢Conners ââ¬Å"The Life You Save May Be Your Ownâ⬠the villain is a one armed hobo named Tom T. Shiftlet. Using his gift of gab and the promise of ââ¬Å"fixing the place up.â⬠He manages to take up on the remote farm of an old woman named Lucynell Crater and her mentally retarded and completely deaf daughter ââ¬Å"Lucynell Craterâ⬠. The old woman quickly decides that despite his handicap she would like to make Tom her son in law. His goal soon became, fix up the old car he was sleeping in and hightail it out of there with the car and some of the old womans money in his pocket. On the pretense that he would need it for a honeymoon trip, he convinces the old woman to fix the car and give him some cash. The story ends with him marrying the retarded daughter, leaving with her on a honeymoon trip, then abandoning her in a rundown diner on the side of the road. ââ¬Å"Good Country Peopleâ⬠is a story about Joy Hopewell, a very well educated young woman living in the rural south. Joy lost a leg in a hunting accident when she was ten and since then had been forced to wear a wooden replacement. She also had a weak heart and it was this affliction that forced her to remain amongst these ââ¬Å"good country peopleâ⬠whom she considered to be intellectual inferiors. Though she had great confidence in her intelligence she had very little self-esteem. Joysââ¬â¢ handicap made her feel ugly, so ugly that much to her mothersââ¬â¢ dismay, she had her name legally changed to the ugliest one she could think of, Hulga. One day a traveling bible salesman named Manley Pointer made a sales call and ended up having dinner with the family.

Thesus vs Achilles
Dumbledore said, ââ¬Å"It is the choicesâ⬠¦ that show what we truly are, far more than our abilities. â⬠This theory applies to everyone. Through the choices and actions of Theseus and Achilles, we learn a lot about their characters. We find Achilles to be motivated by rage and pride, with ambitions of glory and vengeance. Theseus, on the other hand, seems to be motivated by othersââ¬â¢ needs, and aspires to do right by those who he should help. Theseus also likes to challenge expectations and overcome the ââ¬Å"impossibleâ⬠. Theseus begins his saga with a journey to Athens. He chooses the difficult and dangerous land route, as opposed to the sea route, because he wants the challenge. On his way, he completes six tasks that make him a great hero. He kills robbers and murderers, helping innocent potential victims, delivering justice, and making a name for himself. Once he arrives in Athens, he kills some of the people who plan to attack him. Even though they are not innocent and pose a threat to him, he doesnââ¬â¢t kill about half of them, including his uncle Pallas. This shows his solid reasoning. When Theseus captured the bull of Marathon, he met a normal, old lady, and paid her significant respects in her death. Theseus was seen as a ââ¬Å"champion of the oppressed. â⬠For example, he gave Oedipus a place to live after he chose exile. Achillesââ¬â¢ ambitions and motivations had little in common with Theseusââ¬â¢. He was driven by anger, the need for vengeance, bloodlust, and excessive pride. He strived for eternal glory. Achilles played a huge role in the Trojan War, a situation that aligned perfectly with his personality. He showed no humility in slaying others. He mutilated Hectorââ¬â¢s body. He refused to accept Agammemnonââ¬â¢s great gifts out of his hubris. In the end, his need for vengeance overcame even his dispute with Agammemnon, and his sole purpose was to destroy Hector, afterward mutilating his body. He was miserable, but finally learned compassion. Achilles and Theseus were very different heroes. Their choices and actions clearly outline their motivations and ambitions for us. Theseus is motivated by the excitement of challenges, and the opportunity to help others. His ambitions are greatness, but, more importantly, justice and aiding those in need. Achillesââ¬â¢ motivations are negative and his ambitions shallow. However, at the end of his life, we see a positive change in his personality.

How to Become a Good Parent
In this world, parents consider as torchlight for their children. Parents try to do everything for their children whether it is hard or easy for them. Parents gave them directions how to start their new life by themselves. To become a good parent, a person must have all good qualities which are necessary for their children. There are various steps to become a good parent. The first step is to always take care of your children properly. Parents need to give food to children at proper time in an adequate amount. Never leave them alone till age of maturity. Always keep an eye on their daily activities. Parents also need to take information about their children such as who are their friends in schools and neighborhood. They must find out are they good natured students? The second step is that parents must tell their children what is good for them or what is bad. In this way, children can remain safe without anybody elseââ¬â¢s care. If children have already known about bad things, they never do any bad habits. They will always remain far away from bad habits like smoking and gambling. Sometimes, some students start to do bad habits because nobody told them the difference between good and bad. However, parents must tell the disadvantages of bad habits to their children. The third step is to help them in their study. Parents always help their children at the time of any difficulty in their study. Also parents need to decide whether or not children need part-time tutor for their homework. If parents canââ¬â¢t help their children in any difficulties regarding studies, they need to ask the teacher to teach them again on parentââ¬â¢s day. The fourth step is to show your love and also gave them examples of their life experiences. Parents should not shout at their children in front of others. If they will be doing this, children felt their insult and it will lessen their love towards parents. Parents should always teach them in positive way which means with a lot of love. Parents never put so many burdens on their children so that they will become like a burning candle, for example- job along with study, house responsibilities. The fifth step is to teach children, how to survive in this complicated world. Parents teach their children, how to face the difficulties in their life. The guidance and motivation always remains in the mind of children forever because they learned guidance during growing up. Parents must teach their children to think deeply before doing anything, for example- While taking any decision regarding their life goals. In conclusion, by following these steps which are take care, recognizing of bad and good habits, helping them in their study, love, a person can become a good parent. These steps will make a good parent for children who are going to start a new life. The past experiences of parents become lessons for their children in future.

The Outsiders3 essays
The Outsiders3 essays One day after school Ponyboy and his friend Johnny took two Soc girls out to the movies, they were walking home when five Socs jumped them. The Socs were mad at them for taking their girls on dates. Bob (one of the Socs) was about to drown Ponyboy in a fountain when Johnny lost it and stabbed him. The Socs ran and so did Johnny and Ponyboy. After this incident they ran to a church outside of town. One day the church catches on fire. Johnny and Ponyboy save the kids that were playing in the abandoned church. Johnny pushed Ponyboy out of the church right as the roof caved in killing Johnny. Ponyboy and Johnny were heroes. They ruled that Ponyboy was just fighting back in self-defense. Ponyboy eventually writes a book about what has happened to him, the book that Ponyboy starts to write, starts the same way the novel starts. Ponyboy is a nice kid that's parents were killed in a car crash when he was young. Ponyboy has light brown almost red hair, and greenish-gray eyes. He has long hair that is squared off in the back. Ponyboy is a skittish kid; he was always worried about getting jumped by the Socs. But when you are a greaser walking on the streets alone, you have the right to worry about being jumped by the Socs. Ponyboy does a lot of growing up in the book that makes him a dynamic character. He has to cope with a lot of frustration with his two older brothers and with the Socs. He handles it pretty well until one day when he was being jumped by the Socs he spit on one of them that started a brawl that escalated into a murder. Ponyboy has a good relationship with Johnny.

Leo Szilard Biography, Role in Creation of Atomic Bomb
Leo Szilard Biography, Role in Creation of Atomic Bomb Leo Szilard (1898-1964) was a Hungarian-born American physicist and inventor who played a key role in the development of the atomic bomb. Though he vocally opposed using the bomb in war, Szilard felt it was important to perfect the super-weapon before Nazi Germany. In 1933, Szilard developed the idea of the nuclear chain reaction, and in 1934, he joined with Enrico Fermi in patenting the worldââ¬â¢s first working nuclear reactor. He also wrote the letter signed by Albert Einstein in 1939 that convinced U.S. President Franklin Roosevelt of the need for the Manhattan Project to build the atomic bomb. After the bomb had been successfully tested, on July 16, 1945, he signed a petition asking President Harry Truman not to use it on Japan. Truman, however, never received it. Fast Facts: Leo Szilard Full Name: Leo Szilard (born as Leo Spitz)Known For: Groundbreaking nuclear physicistBorn: February 11, 1898, in Budapest, HungaryDied: May 30, 1964, in La Jolla, CaliforniaParents: Louis Spitz and Tekla VidorSpouse: Dr. Gertrud (Trude) Weiss (m. 1951)Education: Budapest Technical University, Technical University of Berlin, Humboldt University of BerlinKey Accomplishments: Nuclear chain reaction. Manhattan Project atomic bomb scientist.Awards: Atoms for Peace Award (1959). Albert Einstein Award (1960). Humanist of the Year (1960). Early Life Leo Szilard was born Leo Spitz on February 11, 1898, in Budapest, Hungary. A year later, his Jewish parents, civil engineer Louis Spitz and Tekla Vidor, changed the familyââ¬â¢s surname from the German ââ¬Å"Spitzâ⬠to the Hungarian ââ¬Å"Szilard.â⬠Even during high school, Szilard showed an aptitude for physics and mathematics, winning a national prize for mathematics in 1916, the year he graduated. In September 1916, he attended Palatine Joseph Technical University in Budapest as an engineering student, but joined the Austro-Hungarian Army in 1917 at the height of World War I. Portrait of Professor of Biophysics, Institute of Radiobiology and Biophysics, at the University of Chicago Dr Leo Szilard (1898 - 1964), Chicago, Illinois, 1957. PhotoQuest / Getty Images Education and Early Research Forced to return to Budapest to recover from the dreaded Spanish Influenza of 1918, Szilard never saw battle. After the war, he briefly returned to school in Budapest, but transferred to the Technische Hochschule in Charlottenburg, Germany, in 1920. He soon changed schools and majors, studying physics at the Humboldt University of Berlin, where he attended the lectures of no less than Albert Einstein, Max Planck, and Max von Laue. After earning his Ph.D. in physics from the University of Berlin in 1922, Szilard worked as von Laueââ¬â¢s research assistant at the Institute for Theoretical Physics, where he collaborated with Einstein on a home refrigerator based on their revolutionary Einstein-Szilard pump. In 1927, Szilard was hired as an instructor at the University of Berlin. It was there that he published his paper ââ¬Å"On the Decrease of Entropy in a Thermodynamic System by the Intervention of Intelligent Beings,â⬠which would become the basis for his later work on the second law of thermodynamics. The Nuclear Chain Reaction Faced with the threat of the Nazi Partyââ¬â¢s anti-Semitic policy and harsh treatment of Jewish academics, Szilard left Germany in 1933. After living briefly in Vienna, he arrived in London in 1934. While experimenting with chain reactions at Londonââ¬â¢s St. Bartholomews Hospital, he discovered a method of separating the radioactive isotopes of iodine. This research led to Szilard being granted the first patent for a method of creating a nuclear chain reaction in 1936. As war with Germany grew more likely, his patent was entrusted to the British Admiralty to ensure its secrecy. Szilard continued his research at Oxford University, where he intensified his efforts to warn Enrico Fermi of the dangers to humanity of using nuclear chain reactions to create weapons of war rather than to generate energy. The Manhattan Projectà In January 1938, with the impending war in Europe threatening his work, if not his very life, Szilard immigrated to the United States, where he continued his research in nuclear chain reactions while teaching at New Yorkââ¬â¢s Columbia University. When news reached America in 1939 that German physicists Otto Hahn and Fritz Strassmann had discovered nuclear fission- the trigger of an atomic explosion- Szilard and several of his fellow physicists convinced Albert Einstein to sign a letter to President Roosevelt explaining the devastating destructive force of an atomic bomb. With Nazi Germany now on the verge of taking over Europe, Szilard, Fermi, and their associates feared what could happen to America if Germany built a working bomb first. Convinced by the Einsteinââ¬âSzilard letter, Roosevelt ordered the creation of the Manhattan Project, a famed collaboration of outstanding U.S., British, and Canadian scientists dedicated to harnessing nuclear energy for military uses. As a member of the Manhattan Project from 1942 to 1945, Szilard worked as the chief physicist alongside Fermi at the University of Chicago, where they built the worldââ¬â¢s first working nuclear reactor. This breakthrough led to the first successful test of an atomic bomb on July 16, 1945, at White Sands, New Mexico. Shaken by the destructive force of the weapon he had helped to create, Szilard decided to dedicate the rest of his life to nuclear safety, arms control, and the prevention of further development of nuclear energy for military purposes. After World War II, Szilard became fascinated by molecular biology and the groundbreaking research being done by Jonas Salk in developing the polio vaccine, eventually helping found the Salk Institute for Biological Studies. During the Cold War, he continued to call for international atomic arms control, the advancement of peaceful uses of nuclear energy, and better U.S. relations with the Soviet Union. Szilard received the Atoms for Peace Award in 1959, and was named Humanist of the Year by the American Humanist Association, and given the Albert Einstein Award in 1960. In 1962, he founded the Council for a Livable World, an organization dedicated to delivering ââ¬Å"the sweetà voice of reasonâ⬠about nuclear weapons to Congress, the White House, and the American public. The Voice of the Dolphins In 1961, Szilard published a collection of his own short stories, ââ¬Å"The Voice of the Dolphins,â⬠in which he predicts moral and political issues to be triggered by the proliferation of atomic weapons in the year 1985. The title refers to a group of Russian and American scientists who in translating the language of dolphins found that their intelligence and wisdom exceeded that of humans. In another story, ââ¬Å"My Trial as a War Criminal,â⬠Szilard presents a revealing, though fantasized, view of himself standing trial for war crimes against humanity after the United States had unconditionally surrendered to the Soviet Union, after losing a war in which the U.S.S.R. had unleashed a devastating germ warfare program. Personal Life Szilard married physician Dr. Gertrud (Trude) Weiss on October 13, 1951, in New York City. The couple had no known surviving children. Before his marriage to Dr. Weiss, Szilard had been an unmarried life partner of Berlin opera singer Gerda Philipsborn during the 1920s and 1930s. Cancer and Death After being diagnosed with bladder cancer in 1960, Szilard underwent radiation therapy at New Yorkââ¬â¢s Memorial Sloan-Kettering Hospital, using a cobalt 60 treatment regimen Szilard himself had designed. After a second round of treatment in 1962, Szilard was declared cancer-free. The Szilard-designed cobalt therapy is still used for the treatment of many inoperable cancers. During his final years, Szilard served as a fellow at the Salk Institute for Biological Studies in La Jolla, California, which he had helped to found in 1963. In April 1964, Szilard and Dr. Weiss moved to a La Jolla hotel bungalow, where he died of heart attack in his sleep on May 30, 1964, at age 66. Today, a portion of his ashes is buried in Lakeview Cemetery, Ithaca, New York, alongside those of his wife. Sources and Further Reference Lanoutte, William.

Essay writting critical thinking A written Critique of a given . 1200 words. Worth 50% of the overall grade - Article Example My findings indicate that most people especially parents, teachers, and religious leaders reject Harryââ¬â¢s works. Their argument is plain and clear. There is no compromise especially when it comes to raising children in the right way in this dynamic world. Harry Porters works have sparked a lot of speculation with many people viewing his works as satanic. However, some people view Harry Porters work as simple magic that replicate in real life. Harry porter writes mostly to children and most of schools and religious groups have banned his books in their institutions. Most people relate his books to fairy tales and Cinderella books, which never received much criticism as his books, are receiving. According to some people, Harry Porter is a Christian though his works are simply illusions considered satanic by some people. Despite the religion attack, most of Harry Porters work avoids religion in its context. Harry Porter argues that his works avoid introducing certain religion to the targeted audience. There has been intense debate about banning the books from US schools though the public view that as intimidation considering that witchcraft is a licensed business in the US. Other countries like United Arab Emirates consider the books il legal in their schools. The books contain positive aspects of good over evil embedded in witchcraft. The books portray the culture of love and courage in witchcraft, which Christian and other religion denounces. However, a critical perception of Harry Porters works indicate that the magic and illusions can be done in real life unlike works such as Lord of Rings which cannot be practiced in real life. Others view works of Harry Porter as stemming from Wicca religion, which usually incorporates witchcraft work. Wicca is gender polarized and the religion worships the moon Goddess and Horned God. It is also important to mention that Wicca contains magic ranging from folk culture magic and low magic, which is greatly, expressed in

Biogeography of bottlenosed dolphins Research Paper
Biogeography of bottlenosed dolphins - Research Paper Example The large brain size and the vocal learning on one hand are the cause of the organism being a major attraction and a source of amusement, and on the other hand render it vulnerable to noise and chemical pollution resulting from anthropogenic activity. The conservation strategies directed at habitat preservation of the organism are recommended. BIOGEOGRAPHY OF BOTTLENOSE DOLPHINS INTRODUCTION Bottlenose dolphins belong to the order Cetacea, the term derived from Greek word ketos meaning whale. The order includes large aquatic mammals with forelimbs modified into flippers, a horizontally flattened tail, lacking hind limbs and with one or two nostrils. The order includes the suborders Odontoceti (toothed whales) and Mysticeti (baleen whales). Most Dolphins are included in the family Delphinidae, belonging to suborder Odontoceti, including the bottlenose Dolphin or genus Tursiops. The genera Tursiops (derived from Latin word Tursio meaning Dolphin or Dolphin like), has been further class ified to include two species on the basis of biochemical and genetic studies: common bottlenose dolphin or T. truncatus and the Indopacific bottlenose dolphin or T. aduncus (Rice, 18). ... The biogeography of an organism provides significant information regarding its evolutionary history and adaptation. Thus biogeography can be considered to include the spatial as well as temporal distribution of an organism. The common bottlenose dolphin T.trucatus enjoys worldwide distribution including tropical and temperate, inshore, coastal, shelf and oceanic areas (Reynolds et al., 12), except the polar region, northward of 45?, though they do occurs far as 62?N7?W in northern Europe. Found rarely in Baltic Sea and vagrant in Newfoundland and Norway, the species is present is as yet uncertain in other areas. The author aims to present in the current paper an account of the biogeography of the common bottlenose dolphin or T. truncatus; along with the evolutionary history of the organism on the basis of fossil records and the threat to conservation programs for the organism specially those relating to its biogeography. BIOGEOGRAPHY Figure 1 The major distribution areas of common bo ttlenose dolphin (figure 1) include the western margins of North Atlantic where the coastal forms occur within a distance of 5km from the land and in bays and estuaries (Mead and Potter, 165). The offshore forms occur within 200-2000m range along the shelf break in regions north and north east to Georges bank (Kenney, 369); and in the Scotian shelf; with the distribution of the two forms overlapping in some zones. The coastal forms are prevalent throughout the year continuously along the North Carolina to Texas (Mead and Potter, 165). In southeastern US they also occur as communities exhibiting specific association patterns and individual home ranges. In the eastern Pacific region, T. truncatus occurs in the
