Comedy used in O`Brother Where Art Thou essays

Comedy used in O`Brother Where Art Thou essays The film O Brother Where Art Thou is a comedic adventure based on the Odyssey by Homer, to whom credit is given. The comedy in this film differs from many other movies. In films such as Jay and Silent Bob Strike Back or any given Jim Carrey comedy the elements of comedy are very obvious and easily laughed at. However, in O Brother Where Art Thou the comedy leans towards being more sophisticate and stereotypical, often being very subtle. While there is the slapstick of two men beaten with a club by John Goodman, who plays a one-eyed Bible salesman, it never fully contributes to the overall humor of the film. The attack of Big Dan played by John Goodman is not the only example of slapstick in this movie. Others include the gang unexpectedly falling out of a train the group is attempting to hitch a ride on. Ulysses, played by George Clooney, seems to be the object of slapstick pain continually, as in another example in this film he fights the seemingly nerd like suitor to his wife and is horribly beaten. The comedy is further escalated in this scene when most of the pummeling takes place off camera as the viewer sees the battled over wife watch the brawl. Fights and falls are, however, not the real substance to the comedic value of this film. Most of the hilarity occurs in subtle satire, mostly exaggerated stereotypes, and often evasive irony. Examples of this irony include the group being saved by their own casket, which they were told to share. Another, more subtle example, is the devil-like man preparing to kill them is in turn killed by water Pete and Delmar believe was sent by God. And while the bible salesman is killed by a burning cross at a KKK meeting, this is not the only incident of racial situations in the film. The stereotype given to Blacks in the 1930s in demonstrated by the blind radio manager, who would not let the group play if they were mostly negros. Another stereotype is the crazy incumbent ...

The Benefits of Paper Recycling

The Benefits of Paper Recycling Paper recycling has been around for a long time. Actually, when you think about it, paper has been a recycled product from the very beginning. For the first 1,800 years or so that paper existed, it was always made from discarded materials. What Are the Most Significant Benefits of Paper Recycling? Recycling paper conserves natural resources, saves energy, reduces greenhouse gas emissions, and keeps landfill space free for other types of trash that cant be recycled. Recycling one ton of paper can save 17 trees, 7,000 gallons of water, 380 gallons of oil, 3.3 cubic yards of landfill space and 4,000 kilowatts of energy - enough to power the average U.S. home for six months - and reduce greenhouse gas emissions by one metric ton of carbon equivalent (MTCE). Who Invented Paper? A Chinese official named Tsai Lun was the first person to make what we would consider paper. In 105 AD, at Lei-Yang, China, Tsai Lun stirred together a combination of rags, used fishing nets, hemp and grass to make the first real paper the world had ever seen. Before Tsai Lun invented paper, people wrote on papyrus, a natural reed used by ancient Egyptians, Greeks, and Romans to create the paper-like material from which paper derives its name. Those first sheets of paper Tsai Lun made were pretty rough, but over the next few centuries, as papermaking spread throughout Europe, Asia, and the Middle East, the process improved and so did the quality of the paper produced. When Did Paper Recycling Begin? Papermaking and producing paper from recycled materials came to the United States simultaneously in 1690. William Rittenhouse learned to make paper in Germany and founded Americas first paper mill on Monoshone Creek near Germantown, which is now Philadelphia. Rittenhouse made his paper from discarded rags of cotton and linen. It wasnt until the 1800s that people in the United States started making paper from trees and wood fiber. On April 28, 1800, an English papermaker named Matthias Koops was granted the first patent for paper recycling - English patent no. 2392, titled Extracting Ink from Paper and Converting such Paper into Pulp. In his patent application, Koops described his process as, An invention made by me of extracting printing and writing ink from printed and written paper, and converting the paper from which the ink is extracted into pulp, and making thereof paper fit for writing, printing, and other purposes. In 1801, Koops opened a mill in England that was the first in the world to produce paper from material other than cotton and linen rags - specifically from recycled paper. Two years later, the Koops mill declared bankruptcy and closed, but Koops patented paper-recycling process was later used by paper mills all over the world. Municipal paper recycling started in Baltimore, Maryland, in 1874, as part of the nations first curbside recycling program. And in 1896, the first recycling center opened in New York City. From those early efforts, paper recycling has continued to grow until, today, more paper is recycled (if measured by weight) than all of the glass, plastic, and aluminum combined. How Much Paper Is Recycled Every Year? In 2014, 65.4 percent of the paper used in the United States was recovered for recycling, for a total of 51 million tons. Thats a 90 percent increase in the recovery rate since 1990, according to the American Forest Paper Association. Approximately 80 percent of U.S. paper mills use some recovered paper fiber to produce new paper and paperboard products. How Many Times Can the Same Paper Be Recycled? Paper recycling does have limits. Every time paper is recycled, the fiber becomes shorter, weaker and more brittle. In general, paper can be recycled up to seven times before it must be discarded.

The Reasons of Abolishing Marriage Essay Example | Topics and Well Written Essays - 750 words

The Reasons of Abolishing Marriage - Essay Example The other thing that is proposed by the author of the article is to allow marriage between two men of the same sex, to let three men get married, or let a person marry himself etc. This argument destroys the notion of a civil marriage as of a cell integrated into the society and, to some extent, detached from the adjacent cells. It is necessary to have a definition of what marriage is, of the relations that connect the spouses and the nature of the relations between them. Originally the marriage as the social institution was seen as a union of a man and woman who love each other and join to live together and give birth to children. This understanding of the marriage and family defined traditional state policies that are directed to the support of families and the kids. In case this traditional notion of the marriage is lost, the social system of supporting the family will be destroyed and replaced by nothing. The sense of a family as regards to the society in general will be lost als o. As the author admits, the abolishing of the civil marriage may lead to a mess in the sphere of the relations between the members of the family in case of living together, as well as in case of divorce. Moreover, it would be impossible to define the degree of the responsibility that in civil marriage lies upon the parents towards their children. The questions concerning the inheritance often confuse the judges at present, so it is impossible to conceive what the situation would be when nobody knows what relations connect the members of the so-called family.

Reality TV in relation to television Essay Example | Topics and Well Written Essays - 1000 words

Reality TV in relation to television - Essay Example As mentioned earlier, the concept of surveillance society has influenced reality TV greatly due to the relationship that exists between the two (Lyon, 2001). For most of the time, TV shows come to the audience in a well scripted and practiced format. Because of this, it becomes very difficult to know what actually takes place in the lives of participants in a very normal life situation. Because such forms of TV programmes are the commonest, the audience finds it difficult to satisfy their surveillance society demands, which demands that they will know what goes on in the lives of people as realistic agents of society. In a study, Trottier (2011) noted that most audiences are constantly looking for the answer to the question of how other people will behave if the people found themselves in situations that audience found themselves in real life. To get a candid answer to such questions, social surveillance becomes the tool that can be used. This is because the concept of surveillance s ociety requires that people will be monitored in their most natural environments. Using reality TV shows â€Å"Big Brother UK†, audience come face to face with how other people behave in everyday natural situations. Basing on Foucault’s idea of a panopticon, however, reality TV may be subdivided into those that inmates are aware they are being surveyed and those that they are not. This is because, from the concept of a panopticon, those who are being monitored are not expected to be aware that there is any surveillance on them.

Properties of Topological Insulating Material: Bi2Te3-PANI

Properties of Topological Insulating Material: Bi2Te3-PANI Synthesis, Characterization and Electrical properties of a Composite of Topological Insulating Material: Bi2Te3-PANI R. R. Urkudea[*], P. T. Patilb, S. B. Kondawarb, U. A. Palikundwara[† ] aX-ray Research Laboratory, Department of Physics, Rashtrasant Tukadoji Maharaj Nagpur University, Nagpur 440033, India bPolymer Nanotech Laboratory, Department of Physics, Rashtrasant Tukadoji Maharaj Nagpur University, Nagpur 440033, India Abstract In the present work, we carried out a systematic study of structure, UV-Vis Spectra and surface conductivity of pure Bi2Te3, pure Polyaniline (PANI) and Bi2Te3 (5%)-PANI (95%) composite. Bi2Te3 was synthesized by a method similar to solvothermal method, whereas, pure PANI and Bi2Te3-PANI composite were synthesized by a chemical oxidative method. The materials were structurally characterized and the electrical properties were investigated in the temperature range from room temperature to 100 °C. The electrical conductivity of the Bi2Te3-PANI composite is found to be higher than that of its pure constituents at all the temperatures. The enhancement in the surface conductivity may be due to the PANI generated ordered molecular arrangement of Bi2Te3 in the Bi2Te3-PANI composite, as confirmed from powder x-ray diffraction, UV–vis spectral analysis.  © 2015 The Authors. Published by Elsevier Ltd. Peer-review under responsibility of the International Conference on Nanomaterials and Technologies (CNT 2014). Keywords: Topological insulators; Bismuth telluride; thermoelectric material; Polyaniline composites; electrical conductivity. 1. Introduction Topological insulators (TIs) are electronic materials that have a bulk band gap like an ordinary insulator but have protected conducting states on their edge or surface (Hasan and Kane, 2010). Most of the current researches are focused on the materials, like Bismuth telluride (Bi2Te3), Antimony telluride (Sb2Te3) and Bismuth selenide (Bi2Se3) due to the topological insulating properties exhibited by them. Bi2Te3 is one of the best TI materials. It is a semiconducting compound with narrow bulk band gap of 0.2 eV. It is also a good material for thermoelectric applications (Das and Soundararajan, 1988). It has shown a drastic change in its thermoelectric properties when it is doped with Polyaniline (PANI) (Li et al., 2011). It has also given added advantages of polymers like inexpensiveness, intrinsically low thermal conductivity, flexibility and good processability etc. (Marjanovic et al., 2013). Various research workers have attempted to synthesize and characterize composites of Bi2Te3 with polyaniline (Zhao et al., 2002; Xu et al., 2005; Hostler et al., 2006; Chatterjee et al., 2009; Toshima et al., 2011). Very recently, mechanical blending method was employed by Li et al. (2011) for the synthesis of Bi2Te3–PANI; they found that the power factor of the composite is less than both of the individual components. However, a report on the synthesis of a Bi2Te3 and PANI hybrid by physical mixing and solution mixing showed a higher power factor in the case of the physical mixture (Toshima et al., 2011). Though there is a vast literature available on the TE properties of Bi2Te3-PANI composites, experimental reports on TI Properties of the composites are not available. Based on this background, in the present work, we carried out a systematic study of structure, UV-Vis Spectra and surface conductivity of Bi2Te3 (5%)-PANI (95%) composite, pure Bi2Te3 and pure PANI. Bi2Te3 was synthesized by a method similar to solvothermal method (Deng et al., 2002), whereas, pure PANI and Bi2Te3-PANI composite were synthesized by a chemical oxidative method (Stejskal and Gilbert, 2002). The materials were structurally characterized and the electrical properties were investigated in the temperature range from room temperature to 100 °C. The electrical conductivity of the Bi2Te3-PANI composite is found to be higher than that of its pure constituents at all the temperatures. The enhancement in the surface conductivity may be due to the construction of highly ordered chain structures of PANI on Bi2Te3, as confirmed from powder x-ray diffraction (XRD), UV–vis spectral analysis. 2. Experimental details 2.1 Materials used Bismuth chloride (BiCl3), Tellurium (Te) metal powder, Potassium hydroxide (KOH), Sodium borohydrate (NaBH4), N-N dimethylformamide (DMF), Hydrochloric acid (HCl), Aniline (C6H5NH2), Acetone [(CH3)2.CO], Methanol (CH3OH) were purchased from Merck Chemicals. Ammonium persulphate [(NH4)2S2O8] was purchased from Hi-media. All the chemicals were of analytical reagent grade and are used without further purification, except aniline which was purified prior to use. 2.2 Preparation of Bi2Te3 A mixture of BiCl3 (10 mmol), Te powder (15 mmol), KOH (80 mmol) and NaBH4 (30 mmol) were put into a beaker of 100 ml capacity. The beaker was then filled with N-N dimethylformamide (DMF) up to 90 ml and was kept into a muffle furnace. Temperature of the furnace was maintained at 100-180 °C for 24 hours and was then slowly cooled to the room temperature. The product was filtered, washed with double distilled water and dried in vacuum oven at 80 °C for 12 hours. 2.3 Preparation of pure PANI and Bi2Te3 PANI Composite PANI was synthesized by using chemical oxidative method (Stejskal and Gilbert, 2002) 0.2 mol Aniline with 0.25 mol Ammonium persulphate was oxidized in acidic aqueous medium. Aniline and Ammonium persulphate were dissolved, separately, in 50 ml solution of 1.0 mol HCl in double distilled water. Both the solutions were kept at room temperature for 1h and were mixed together in a beaker. During the process, the colour of the solution changed from colourless to light blue and then to dark green. The solution was briefly stirred and was left to polymerize for 24 h. The precipitate of PANI was collected on a filter paper, washed with distilled water, then with 20 ml of 0.1M HCl and with Methanol. PANI (emeraldine salt) powder was dried in vacuum oven at 80 °C. A similar procedure was followed for the synthesis of Bi2Te3-PANI composite, but this time Bi2Te3 was introduced in aniline solution. 3. Characterization 3.1 Structural characterization The samples were structurally characterized by XRD and UV–vis spectral analyses. XRD measurements were performed using a Diffractometer (Rigaku Miniflex II x-ray Diffractometer) with Cu KÃŽ ± radiation (ÃŽ » = 1.541838 A °). The UV–vis spectra of the prepared samples were recorded by a spectrophotometer (UV-1800 Shimatzu Spectrophotometer) using samples dissolved in dimethyl formamide in a quartz cuvette. 3.2 Electrical characterization All the prepared samples were pressed at pressure less than 5 tonnes, at room temperature, to form the compacted pellets for measurement of the electrical conductivity. The measurements were carried out, in the temperature range 20-100  °C, by standard four-probe method with constant current source kept at 2 mA. 4. Results and Discussions 4.1 Powder X-ray diffraction Figure 1 shows the XRD patterns of Bi2Te3, pure PANI and Bi2Te3-PANI composite. All the peaks of the pattern for Bi2Te3 can be indexed in rhombohedral structure (JCPDS No: 015-0863) with unit cell parameters: a = 4.358A °; b = 4.358A ° and c = 30.48A °. Broad peaks at 22 ° and 25 ° for pure PANI are observed, which are due to the repeat unit of monomer. Compared with the pure PANI, only one peak is clearly observed at 25 °, the same position, in the XRD pattern of Bi2Te3-PANI composite. The observation of a single peak is related to the monodistribution of the periodicity of the repeat unit of the PANI and ordering of the molecular arrangement of the Bi2Te3 in the PANI matrix (Talwar et al., 2014). This suggests that PANI generate an ordered molecular arrangement of Bi2Te3 in the Bi2Te3-PANI composite. Figure 1 XRD patterns of Pure PANI, Pure Bi2Te3 and Bi2Te3-PANI composite 4.2 UV-vis spectroscopy Figure 2 shows the UV–vis spectra of the samples used to explore the electronic states of Bi2Te3, pure PANI and the Bi2Te3-PANI composite. A characteristic band centred at 697 nm, a shoulder at 478 nm, corresponding to a polaronic transition (polaron- Ï€*) and a band around at 389 nm, assigned to the π–π* electron orbital transition are observed in Bi2Te3-PANI composite. In comparison with UV–vis spectra of the pure PANI: a band around 385 nm, assigned to the π–π* electron orbital transition, shifts to longer wavelength at 389 nm in Bi2Te3-PANI composite. The polaronic transition (polaron- Ï€*) is absent in the pure PANI but is observed in Bi2Te3-PANI composite. These show an interaction between the quinoid ring of PANI and Bi2Te3 (Xia and Wang, 2003). This is a signature of an ordered molecular arrangement in Bi2Te3-PANI composite and it is the purely surface conducting state. Figure 2 UV-vis spectra of Pure PANI, Bi2Te3 and Bi2Te3-PANI composite 4.3 Electrical characterization Figure 3 Variation of the electrical conductivity with temperature of Bi2Te3, PANI and Bi2Te3-PANI composite. The variations of electrical conductivity as a function of temperature of the prepared samples are shown in figure 3. The value of electrical conductivity for Bi2Te3 slightly decreases with the increase in the temperature. However, both PANI and Bi2Te3-PANI composite show increase in the value of electrical conductivity with temperature. The electrical conductivity of the Bi2Te3-PANI composite is higher than that of its pure constituents over a whole temperature range. The enhancement in the surface conductivity indicates the increase in protected states at the surface compared to that of the pure Bi2Te3. This may be due to the large surface provided to the Bi2Te3 by the PANI generated ordered molecular arrangement of Bi2Te3 in the Bi2Te3-PANI composite. 5. Conclusions In conclusion, we carried out a systematic study of structure, UV-Vis Spectra and surface conductivity of Bi2Te3 (5%)-PANI (95%) composite, pure Bi2Te3 and pure PANI. Bi2Te3 was synthesized by a method similar to solvothermal method, whereas, pure PANI and Bi2Te3-PANI composite were synthesized by a chemical oxidative method. The materials were structurally characterized and the electrical properties were investigated in the temperature range from room temperature to 100 °C. The electrical conductivity of the Bi2Te3-PANI composite was found to be higher than that of its pure constituents at all the temperatures. The enhancement in the surface conductivity may be due to the PANI generated ordered molecular arrangement of Bi2Te3 in the Bi2Te3-PANI composite, as confirmed from powder x-ray diffraction (XRD), UV–vis spectral analysis.

Foodborne Illness Short Answer Questions

Complete answers to questions below: What is the infectious agent (pathogen) that causes this infectious disease? For example, the name of the bacteria, virus, or parasite. The process of infection can be broken down into stages, each of which can be blocked by different defense mechanisms. In the first stage, a new host is exposed to infectious particles shed by an infected individual. The number, route, mode of transmission, and stability of an infectious agent outside the host determines its infectivity.Some pathogens, such as anthrax, are spread by spores that are highly resistant to heat and drying, while others, such as the human immunodeficiency virus (HIV), are spread only by the exchange of bodily fluids or tissues because they are unable to survive as infectious agents outside the body. How is this infectious agent transmitted through food or water? Infectious pathogens include some viruses, bacteria, fungi, protozoa, multicellular parasites, and aberrant proteins known as prions.These pathogens are the cause of disease epidemics, in the sense that without the pathogen, no infectious epidemic occurs. The term infectivity describes the ability of an organism to enter, survive and multiply in the host, while the infectiousness of a disease indicates the comparative ease with which the disease is transmitted to other hosts. Transmission of pathogen can occur in various ways including physical contact, contaminated food, body fluids, objects, airborne inhalation, or through vector organisms What is an example of a real life outbreak of this foodborne illness in the United States?In early October 2012, the Clark County Public Health Department (â€Å"the health department†) received the first reports of a cluster of Salmonella Virchow infections occurring in the county. Additional reports came in rapidly, and by October 9, interviews of ill persons indicated that the source of the developing outbreak was the On the Border restaurant in Vancouver, Wa shington. On October 9, On the Border temporarily ceased operation. Dr. Alan Melnick, Clark County Health Officer, stated that the closure was â€Å"a further precaution to reduce the risk of Salmonella spreading to others. Meanwhile, health department staff continued to interview employees and patrons of the restaurant to learn more about the precise cause of the outbreak. The health department also continued its work with On the Border employees to make sure that standard control measures—e. g. hand-washing and environmental sanitation—were in place and effective, so that when the restaurant resumed operation it would not pose a continuing threat to the health of its patrons.As of the date of the restaurant’s closure on October 9, there were 11 confirmed and five probable cases of Salmonella Virchow infection linked to the consumption of food at the restaurant.  · What are the clinical symptoms, duration of the disease, and treatment if any? Viral hepatitis ; Infectious hepatitis The hepatitis A virus is found mostly in the stools and blood of an infected person about 15 – 45 days before symptoms occur and during the first week of illness.You can catch hepatitis A if: You eat or drink food or water that has been contaminated by stools (feces) containing the hepatitis A virus (fruits, vegetables, shellfish, ice, and water are common sources of the hepatitis A virus You come in contact with the stool or blood of a person who currently has the disease, A person with hepatitis, A does not wash his or her hands properly after going to the bathroom and touches other objects or food, You participate in sexual practices that involve oral-anal contact, About 3,600 cases of hepatitis A are reported each year.Because not everyone has symptoms with hepatitis A infection, many more people are infected than are diagnosed or reported. Risk factors include: International travel, especially to Asia or South or Central America IV drug use, living in a nursing home or rehabilitation center, working in a health care, food, or sewage industry What steps can be taken to prevent further outbreaks? Include individual as well as environmental precautions and methods. Preventing hepatitis A: The virus causing hepatitis A is mostly contracted through food and water.Therefore, proper hygiene is very important in this case. Drink filtered water that is free from any kind of germs and viruses. Make sure that the water which you are getting in your house is filtered properly. If you are travelling, then use only commercially bottled water that is sealed properly. Boiling the water before drinking is also helpful in killing the viruses that cause hepatitis. Wash your hands properly before touching any food items and after using the toilet. Follow proper sanitation in and around your house. Eat food that is cooked well and is fresh.

Decision Analysis The Decision - 1528 Words

Introduction Decision analysis provides powerful techniques to structure complex problems, identify optimal choices, and facilitate communication between the decision analyzer and the person makes the decision. One of the most important values of these techniques is that they enable decision making to be rational rather than intuitive or holistic. They provide a framework for rational decision making in an uncertain environment. As modern decision analysis has been studied for more than five decades, there has been significant improvements in the practices used. These methods have been implemented by companies and organizations and proved to be successful as well as constructive. However, there are also plenty of examples when the recommendation were not implemented or even if they were, they failed to truly support the decision maker(s). Kusnic and Owen found that the implementation rate decreases with the importance of the problem (1992). These cases, however, enabled scientists detect the major deficiencies of this approach, and helped them to work out new developments to help overcome these limitations. The aim of this paper is to give insight into the process of decision analysis with the help of real life examples and case studies, and show the extent to which the approach has proven to be beneficial. The paper also going to summarize the limitations of decision analysis as well as the techniques that have been developed over the time.
