Michael Crichton essays

Michael Crichton essays Michael Crichton has presented the reader with some of the most engaging, timely, and thoroughly accessible tales to be published in the last twenty-five years. His works are well known to the public and are very popular due to the simplicity of the books context. Unlike the early writers, such as Steinbeck and F. Scott Fitzgerald, who use a lot of imagery, irony, and symbolism to illustrate the big picture and challenge the human mind, Crichton uses rather primitive but captivating dialogue. And his works show that a book doesnt require complex wording and vivid description to make it colorful and interesting. Michael Crichton adopts his writing to the modern generation of readers and gave them what they wanted, a unique story in addition to rapid plot development. Crichton by far has taken the lead with his novels that supersede the average modern writer. What his novels lack in literary merit and distinctive style they make up for in fast character development and edge-of-your-sea t suspense. The literary approach to a novel is an important factor that each writer considers before writing a book. From the early writers to the modern writers, they each considered how they should approach the book. Should they dazzle the reader with complexions, long descriptive passages, vivid images or just fast paced suspense using dialogue that the reader can relate to and understand? Most early writers took the more creative method, they used the language as it was spoken in the early times and used it in their descriptions. Often writers like Steinbeck who wrote in dialogue applied the dialect of the location that the event was taking place. In his book Of Mice and Men, Crooks says S'pose you didn't have nobody. S'pose you couldn't go into the bunk house and play rummy 'cause you was black. How'd you like that? S'pose you had to sit out here an' read books. Sure you could play horseshoes till it got dark, but then you got to re...

Frequency Response of Netwroks (Electronic Engineering) Lab Report

Frequency Response of Netwroks (Electronic Engineering) - Lab Report Example Current was determined by monitoring the voltage across 100 ? resistor. The CRO was used to record the current and voltage waveforms. The above procedure was repeated for the series connection of a resistor and inductor. Voltage across the inductor was measured at 100 Hz. The frequency response of the RC low-pass filter was measured over the frequency range 100 Hz to 100 kHz. At R = 1 k?, C = 0.01 Â µF, the attenuation at 15 to 20 frequencies were logarithmically recorded over this range. This procedure was repeated with R= 10 k?. The LF oscillator was connected to the RLC series circuit and with R=100 ? the voltage across the capacitor and inductor, and current through the circuit at frequencies between 1 kHz and 100 kHz determined by measuring the voltage across the series resistor. The band-pass filter circuit was constructed and voltages Vo and Vi measured over the range of frequencies 1kHz to 100 kHz. The band-stop filter circuit was also constructed and Vo and Vi again measure d over the range of frequencies 1kHz to 100kHz. A Twin-T filter was then constructed with R1 = R2 = 100 ? and C1=C2=0.01Â µF. ... 1000 4.673 0.301 0.00301 1552.492 0.000644 2000 4.627 0.561 0.00561 824.7772 0.001212 3000 4.551 0.83 0.0083 548.3133 0.001824 4000 4.47 1.093 0.01093 408.9661 0.002445 5000 4.37 1.32 0.0132 331.0606 0.003021 6000 4.253 1.596 0.01596 266.4787 0.003753 7000 4.11 1.802 0.01802 228.0799 0.004384 8000 3.962 1.989 0.01989 199.1956 0.00502 9000 3.84 2.123 0.02123 180.8761 0.005529 10000 3.701 2.268 0.02268 163.1834 0.006128 Figure1 The capacitance is the gradient of the line which is 6?10-4 F By calculation C= 1/2?f Xc and at f =10000 Hz and Xc =163.1834 ? then, C = 1 / 2*?*10000*163.1834 = 0.4126 F which reasonably agrees with the experimental values.

Movie Review Example | Topics and Well Written Essays - 500 words

Movie Review Example For that reason, people need to come up with solutions for this crisis. In this essay, I shall try to review the solutions given in the documentary. First, we shall tackle water wastage. It is a miracle that people can take up to one hour in the shower. This is a clear wastage of water. People need to take shorter showers or better yet resort to baths, which would require the use of less water. The film also talks about the pollution of fresh water sources that prevent the use of water. An example of such pollution involves the use of the herbicide Atrazine. This herbicide is still used in the United States of America, despite being banned in countries such as Switzerland. The herbicide is so toxic that it decreases fertility in human males by reducing their sperm count and also causes prostrate and breast cancer. Therefore to solve this problem, the state needs to ban the use of all toxic chemicals that pollute our fresh water reservoirs. The next documentary that I shall review is called â€Å"The Intersection Between Justice and Sustainability: Voices and Views from South Phoenix†. This documentary mainly involves interviews carried out on the residents of South Phoenix. In this essay, I shall reflect on the actions taken by community leaders profiled in the film to address the 10 sustainability principles. In every city, social inequality, marginalization, and containment are some of common injustices experienced. One of these community leaders is Steve Brittle the founder of Don’t Waste Arizona. This is a non-profit environmental organization that was formed to protect, conserve, and preserve human and natural environment. One of the main problems that Phoenix faces comes from Innovative Waste Utilization. This company is located in a neighborhood mainly comprising of African American and Latino families and poses great hazard to these families. Furthermore, this waste facility planned to

Music Since World War II, Concert Review Essay Example | Topics and Well Written Essays - 1250 words

Music Since World War II, Concert Review - Essay Example There are many types and styles of music written since World War II, the only limit is the composer’s imagination. They are looking for different modes of expression. Composer Arnold Schoenberg experimented strange and unorthodox tonal schemes and harmonies. Bela Bartok, a Hungarian composer, combined the Twentieth Century forms with music of Hungarian peasants. Edgard Varese who belongs to the group of ‘Avant-garde’ experimented with the manipulation of rhythms. Igor Stranimsky, throughout his entire career made experiments with kaleidoscopic rhythms and instrumental colors. So it is very clear that composers since Second World War made lots of experiments with traditional instruments and modes of expression. Yet some of the greatest composers of the twentieth century, such as Giacomo Puccini, an Italian opera composer and Sergei Rachmaninoff, the Russian composer, followed traditional forms of music history. Music since World War II has seen several new and ecle ctic styles. Under the musical direction of David Currie, the Ottawa Orchestra presented a concert entitled ‘A French Connection’ comprising of the compositions of Pierre Merure, Steven Gellman and Camille Saint Saens. Pierre Merure discovered French music and developed an interest for orchestration which was very much visibly noticeable in his very first work ‘kaleidoscope’

Oedipus Is to Blame in Oedipus Rex Essay -- Oedipus the King Oedipus R

Oedipus Is to Blame In Sophicle's Oedipus The King, Oedipus plays the lead character in the play. Oedipus plays blindfolded throughout the play. His character that he betrays is typical of those who honestly believe they have no part in the situation that occurs. I agree with Bernard Knox that Oedipus is responsible for the tragic outcome of the play. Oedipus's investigation of the death of King Laius is the reason for the tragic ending. The scene where Oedipus opens the investigation is the first step toward his downfall. Oedipus covers up the murder and is nervous when he hears the news. It is Oedipus's continuous effort to find the murderer. He wants to find the murderers of the king, not knowing that he is the murderer. Oedipus is the head investigator for the murder of King Laius. Even though he tells the people of Thebes that, "I am ready to help." He promises the people that he would do anything t...

Food Inc, opinion paper Essay

Question 1: Based on your viewing of Food, Inc., how does your view of â€Å"farm-fresh† and other marketing messages that suggest a more organic flow of food products relate to the realities of 21st-century marketing channels for food? The American Marketing Association defines marketing as â€Å"the activity, set of institutions, and processes for creating, communicating, delivering, and exchanging offerings that have value for customers, clients, partners, and society at large† (https://www.ama.org/AboutAMA/Pages/Definition-of-Marketing.aspx). The marketing mix consists of product, price, place, promotion, which means that a company needs to sell the right product at the right price and in the right place, using the best promotion. Because of all of this, â€Å"farm-fresh† and organic foods must fight in the marketplace against traditionally farmed foods. Looking at the product: what exactly makes a food organic? Organic can mean different things to different people, and even has a different meaning between companies. According to organic.org, the USDA defines organic food as that which is produced with emphasized use of renewable resources, plus conservation of soil and water. Organic food is produced without conventional pesticides, fertilizers made with synthetics or waste, bioengineered, or ionized radiation. â€Å"Organic meat, poultry, eggs, and dairy products come from animals that are given no antibiotics or growth hormones† (http://www.organic.org/home/faq). A government-approved certifier must inspect farms where organic foods are grown to assure that the farmer follows all USDA rules and meets organic standards. Price is a large factor when most people go grocery shopping, especially during these tough economic times. Many, including myself, can argue that organic or â€Å"farm-fresh† foods are just too expensive to buy on a regular basis, or even at all. Personally, I will buy whichever brand is cheapest, without paying attention to where or how it is produced. According to organic.org, one should consider the following facts when wondering why an organic product might cost more than it’s traditionally grown counterpart: Conventional farmers receive federal subsidies, while organic farmers do not, so the price of organic food reflects the true cost of growing. Environmental cleanups, that we pay for with our tax dollars, is not reflected in conventional food. Organic production is more labor and management intensive. And finally, organic farms do not benefit from the economies of scale that larger, more conventional farmers receive. The placement of organic foods is generally next to conventional foods in most grocery stores. Some stores may have a separate organic section, or the organic product could be placed next to its conventionally grown counterpart. Some grocery stores, such as Natural Grocers, only sell USDA approved organic or naturally grown produce and meat, and would not be concerned with placement. Organic foods are generally promoted as being more nutritious than conventional foods. Although, organic.org admits that there is not research to back this claim, at this time, there are studies that show that organic food has a higher nutritional value. This makes since, considering they are grown more naturally, with less chemicals. This film does expose something about organic or â€Å"farm-fresh† foods: the American food industry is supposed to be protected by the USDA and FDA, but they have been allowing these suppliers to focus on profit and put aside consumer health, the environment, and worker safety. Question 2: Based on your answer to Question 1, are you likely to change how and where you procure your foods (i.e., grocery stores, farmers’ markets, fast-food outlets)? Please explain your reasons. I have never been concerned about how my food was made or where it came from. I have never paid attention to organic foods, GMOs, all-natural, or anything related to the production of the foods I eat. As far as I know, my parents never paid attention to these things either. Because of this, â€Å"farm-fresh† and other marketing of organic foods has not affected me. I just purchase the foods that I want and pay no attention to whether they are â€Å"farm-fresh†, organic, locally grown, etc. I will buy whatever is cheapest,  not whatever is healthiest, most natural, or whatever. My opinion and food purchasing habits will most likely not change after viewing this movie. This question reminds me of high school health class, where we had to watch â€Å"Supersize Me.† Everyone started saying how gross it is, that they are never eating at McDonalds again, or whatever other promises they were making. All I could think was that I could totally go for some McNuggets after school that day! I guess it is just because I have never worried about where the food I eat comes from. However, I have always paid attention to salmonella and E. coli recalls. I remember not eating beef or spinach or peanut butter when there was an outbreak in their plants, because why would I want to get sick? So, I would say no, I will not change where or how I procure my groceries. I will not say that I did not get sad watching those little baby chicks die, or the chickens getting slung around. And those poor cows getting slaughtered, and that one that had that hole and the guy was digging around in her stomach, and said that she was not in pain†¦how does he know?! He’s just cut a big hole in her and is sticking his hand in her stomach, and she cannot tell you that she is in pain! Question 3: Finally, do you think there are any ethical and/or social responsibility issues that confront marketing channels for food distribution? Chicken are manipulated to grow bigger breasts, tomatoes are genetically engineered to not go bad by being picked while they are green, then ripened with chemicals. Tens of thousands of Americans get sick from new strains of E. coli every year. Levels of obesity are shooting upwards, and diabetes in adults and children have reached epidemic proportions. If Americans knew how corporations used subsidies and exploited laws to make more money, would they think more carefully about what they are eating? The truth is, most people have no clue where their foods come from. Below, I will list secrets and other things that the public should know about the food that they are putting into their bodies. I found a list on www.takepart.com (http://www.takepart.com/photos/food-inc-facts/the-impact-of-food-inc-lives-on-) of 18 â€Å"Food, Inc.† facts that everyone should know, which I have compared  with my notes and compiled the following paragraphs. I feel that if everyone was aware of these facts, it would increase the social responsibility of these companies, and people would have trust in them. These facts pertain to the slaughterhouses and meat packers. In the 1970s, the top five beef packers controlled about 25% of the market, while today, more than 80% of the market is controlled by the top four. In the 1970s, there were thousands of slaughterhouses producing the majority of beef sold, while today, there are only 13. In 1972, the FDA conducted 50,000 food safety inspections. Approximately 32,000 hogs a day are killed in Smithfield Hog Processing Plant in Tar Heel, NC, the largest slaughterhouse in the world. In 2006, the FDA only conducted 9,164. These facts pertain to Monsanto and the USDA. Prior to renaming itself an agribusiness company, Monsanto was a chemical company. In 1996 when Monsanto introduced Round-Up Ready Soybeans, the company controlled only 2% of the U.S. soybean market. Now, over 90% of soybeans contain Monsanto’s patented gene in the United States. In 1998, the USDA implemented microbial testing for salmonella and an E. coli strain so that the USDA could shut down the plant if they repeatedly failed these tests; the USDA no longer has this power after being taken to court by the meat and poultry associations. These facts pertain to the FDA, USDA, and congressmen. During the Bush administration, the head of the FDA was the former executive vice president of the National Food Processors Association. Also during the Bush administration, the chief staff at the USDA was the former chief lobbyist for the beef industry in Washington. Supreme Court Justice Clarence Thomas was an attorney at Monsanto from 1976-1979; after his appointment to the Supreme Court, Justice Thomas wrote the majority opinion in a case that helped Monsanto enforce its seed patents. The SB63 Consumer Right to Know measure, requiring all food derived from cloned animals to be labeled as such, passed the California state legislature before being vetoed in 2007 by Governor Schwarzenegger, who said that he couldn’t sign a bill that pre-empted federal law. The rest of these facts are just interesting. The average chicken farmer (with two poultry houses) invests over $500,000, but only makes $18,000 a year. The average American eats over 200 pounds of meat each year. The modern supermarket stocks, on average 47,000 products, most of which are being produced by only a handful of food companies. About 70% of processed have some genetically modified ingredients. According to the American Diabetes Association, 1 in 3 Americans born after 2000 will contract early onset diabetes. Among minorities, the rate will be 1 in 2. E. coli and salmonella outbreaks have been more frequent in America. In 2007, there were 73,000 people wicked by the E. coli bacteria. Organics is the fastest growing food segment, increasing 20% annually.

Drug Discovery And Development Of New Medicine - 1417 Words

Describe and discuss recent developments in drug discovery. As our society is evolving so is diseases many drugs that were previously effective to cure certain diseases are simply not as effective any more or on the other hand there isn’t sufficient medicine to battle the current new health problems that are arising with our evolving society for example obesity and a range of cardiovascular diseases. In addition many of the medicine available today either only treats the symptom or cures the disease with the addition of unwanted side effects. Hence, this is why drug discovery and development is vital. It is through drug discovery and development that new medicine is found. Currently a lot of effort is going into Binuclear metallohydrolases as a target in drug development. This is due to the fact this enzyme group has the potential to find solutions to health problems such as erectile dysfunctions, osteoporosis, cardiovascular dieses and also even become the seed in possible eradication of some antibiotic resistance. The main enzymes in the binuclear metallohydrolases group that are most vital us are purple acid phosphatases, metallo-ÃŽ ²-lactamases and arginases. The homologous feature in all these enzymes is the existence of two very nearly touching metal ions that hold the ability to attract water molecules that will then act as a nucleophile in a very particular hydrolytic reaction the importance of this is that it means that binuclear acids will have a powerful ionicShow MoreRelatedA Brief Note On Malaria And Its Effects On The Worlds Poorest1441 Words   |  6 Pagesor Medicine, diseases like malaria â€Å"have plagued humankind for a millennium and constitute a major global health problem.
