European Union Enlargement - Essay Example From this study it is clear that  Turkey is most prospective country to join the Union with the aim of proving that Islam is compatible with western values and culture. All Balkan nations are also eligible enough to become potential members of the union. The move is aimed at ensuring peace is maintained. All this activities prove that the union is becoming very powerful. This enlargement however may cause the splitting of the union due to various social economic and political challenges facing it.This paper outlines that European Union, however, has been torn apart by two conflicting visions. One of the ideas is the Euro-nationalism or multi polarity that Tony Blair intensely opposes. Some members want the European Union to be an independent actor and lock out the United States. The other idea is referred to as Atlanticism, where the western alliance is maintained fully. When polls were conducted results showed that many members wanted the EU to be a super power like America. A few activities by the increasing size of the AU members are causing the European Union to fall behind economically. They involve the supervision of the Euro, the argument on Iraq and the constitution.  The foreseeable constrain that seems to be facing union has given the union a wakeup call to cautiously evaluate the challenges and risks of trying to expand and increase more members.  The greatest worry among top officials is the eastern expansion and the economic consequences that will be experienced.

General Motors - Research Paper Example Management isolation slowed down GM’s ability to recognize and to adapt to a rapidly changing environment. The company failed to recognize the following: (1) that their American consumers’ wallets were getting tighter and that probably they needed smaller and more fuel-efficient vehicles like Toyotas; (2) they forgot to keep a close eye on their competition (Toyota beating them on economical cars and BMW beating them on luxury and coolness); (3) that their structure and culture was impeding them to compete effectively (Staff 14). The US Government’s bailout Joseph Bower, Harvard’s Baker Foundation Professor of Business Administration, like many wondered whether it was right for the US government to support one competitor (GM) against a group of healthy rivals (Staff 16). Of course fears of government intervention have been justified through lessons from history demonstrating governments’ poor stewardship of industry. However, this time round Mr.

Circular Dichroism and Secondary Structure of Proteins Essay Example for Free

Circular Dichroism and Secondary Structure of Proteins Essay Proteins are vital to an organism life; they are involved in nearly all cellular functions. It is an essential part of enzymes, the cellular membrane, active transport, protein synthesis and wound healing. Because one relies so heavily upon proteins and its function the structure of proteins is also very important. â€Å"The way a protein will fold over its self-determines how it interacts with other chemicals in its proximity, primarily because of different attractive forces being subjected at specific angles from certain amino acids on the protein’s primary structure and the final shape in the tertiary and quandary structure (Circular dichroism ). † The structure of proteins can range from simple to complex molecules. Proteins may consist of a primary, secondary, tertiary, and quaternary structure. The secondary structure consists of hydrogen bonds which join amide and carboxyl groups. These bonds aren’t far from the backbone of proteins. This structure is capable of structures such as alpha helicies, beta sheets, and beta turns (Jim, 2007). The physical, secondary structure is important because it helps in determining the activity of a protein. Circular Dichrosim spectroscopy has been identified as prevalent application used in structural biology in determining whether a protein is folded, characterizing its secondary structure, tertiary structure, and the structural family along with other uses as well (Circular dichroism ). Circular dichroism, CD spectroscopy has defined a form of light absorption spectroscopy. It measures the difference in the absorption of circular polarized light by a substance on the right and left. The secondary structure of a protein can be analyzed between the spectrum of approximately 260 and 180 nm. Estimates of secondary proteins can be compared to X-ray crystallography or NMR (Kelly, Jess, C., 2005).The structures identified in this spectrum are the alpha helix, parallel and antiparallel beta sheet, and turns (Berndt, 1996). The only drawback with CD is that even with the implied spectrum, it has been found that there is no exact standard reference spectrum for a pure secondary structure. Synthetic homopolypeptides used to obtain reference spectra are in general, poor models for the secondary structures found in proteins (Berndt, 1996). The CD signal reflect the entire molecular population; it can determines how much of a certain structure and protein contains. It cannot determine the specific residues involved in the alpha-helical portion. In Circular Dichroism a linear polarized light passes through a optically active sample of a protein. This protein has a different absorbance for components. The amplitude of the stronger absorbed component will smaller than that of the less absorbed component. A projection is created of the resulting amplitude. The result is no longer a linear line but and ellipse (PARTHASARATHY, 1985). Different analyses have been developed to help with various contributions that arise from the different types of secondary structures present in a single molecule. The use of reference spectra have been created from known protein structures to help find the overall and secondary structure of unknown proteins (Whitmore A., 2007). â€Å"Recently a new reference dataset of SRCD spectra of proteins of known structure, designed to cover secondary structure and fold space (Berndt, 1996).† Works Cited Berndt, K.

Rock N Roll And Technological Advancements Media Essay

Rock N Roll And Technological Advancements Media Essay Just in the middle of the 20th century, in the1950s, the world was introduced to a brand new trend in music. That was rock N roll. Rock N roll seriously changed the concept and image of popular music. This new trend originated from rhythm and blues of 1940s together with jazz, swing, boogie woogie, blues, gospel, western, country and traditional country music. With so many old genres being emerged and mixed, there was also a need for a new sound, for a new power of music reaching as many ears and hearts as possible. Thus, technological advancements were just at the service of rock n roll. One of such crucial advancements was the development of stereophonic sound: at least two separate audio channels were used to transfer sound through two or more loudspeakers. This technology provided the illusion performance heard from different directions and audible perspective. In this way, reproduced sound became closer to natural hearing. The principle of stereo typing looks like putting two microphones in specially defined locations. Both microphones are recording at the same time, synchronously. In fact, stereo sound was invented already in 1881 when the visitors of Paris Electrical Exhibition could here the performance from the stage of Paris Opera due to the 2-channel audio system presented by Clement Ader. The exhibitors were given two telephonic receivers, independent for each ear and could experience the presence effect. In 1931 multinational music company, the EMI Group and specifically Alan Blumlein special two-channel system and in 1933 patented stereophonic recording technology cutting a stereo disc carrying two channels by means of two walls of the groove put t right angles. But only in 25 years this method was fated to become a standard one for stereo phonographs. To make stereo available for public, Emory Cook introduced a binaural recordings for commercial reproduction as the interest to such recording and demand for proper equipment was growing. By autumn of 1957 stereo recording became really widespread through the United States. It gave vast opportunities for experiments with sound, so the musicians could not help using them actively. Consequently, both African American Blues and rock n roll music were highly varied after stereo was introduced. By that time, the same stations broadcasted both mono and stereo sound sources. As Deanna R. Adams states, stereo recording of contemporary music w as becoming more common, providing yet another reason that made FM more attractive and by different reasons high-fidelity stereo transmission was becoming more and more popular (Adams 102). Further, there were crucial shifts in the quality of music delivery. Rock n roll opened the new era with stereo vinyl becoming the prevailing media for all the recorded music. Meanwhile, the Germans invented magnetic type and this was a new word to high fidelity recording with synchronized multichannel method. Hereby, tape recorders came from technological experiments conducted in Germany of the World War II times. In the United States, in turn, a high-quality tape recorder was installed by Ampex Corporation. Plastic tape was perfected by Minnesota Mining and Manufacturing (3M), and better sound was also reached through the invention of condenser microphones (Biagi 92). Recording was invariantly important because, certainly, not everyone could attend stage concerts or shows. Magnetic tape made the recordings more long-term in use and easier to spread; so, more and more people could here the same music in different corners of the country and were more and more stimulated to buy tapes and tape recorders. Thus, it was a continuous process of scaling: Its interesting to note that with the growth of popularity in music spread, brought about largely by the hysteria surrounding Rock n Roll, so the technology to support music picked up the pace too. It means that it was a reciprocal exchange of benefits. Technologies provided new opportunities for sound recording and distribution as well as quality of sound, while better sound influencing the rating of rock n roll resulted in boom in production of those technologies. This is how music started the way of becoming a kind of business. Still, rock n roll was not as commercial as it may seem; on the contrary, musicians were really working hard in search of something new and fresh. Among other techniques, they directed their attention to various electronic effects. Electric guitar was one more gripping innovation of those days; Charlie Christian was first to record the instrument as a virtuoso, thus driving the whole nation mad. Electric guitar made the world of sounds richer, and what is more, it provided much louder sound so that more people could here it in the distance. Musicians exploited various amazing effects like distortion, fuzz and overdrive, all noisy and buzzy so much that even called doubts on whether it still was music. Guitar extortion was not accepted affirmatively; the ear was to get adjusted to it. But that was an era of sensory explosion; young people were actively experimenting with sensory-enhancing drugs, so that music was accepted as being right on the wave. Distortion in guitar was produced by transistor and diode clipping. While at first distortion was natural because amplifiers were low-fidelity and primitive, further, when rock was conquering the world, inventive musicians learnt to turn weaknesses of the instruments into virtues. Thus, intentional distortion was applied by poking strings or speakers with pencils, screwdrivers and even blazes. Shocking sounds, often reminding some voices like wolf howling or alarm, provided a special charm for rock music. Distortion gained mad popularity after Dave Davies (The Kinks) recorded the single You Really Got Me through a small amp with speaker cone cut with a razor blade. Later distortion became used on purpose and became commercial and contributing essentially to the popularity of rock n roll music. Finally, one more influential advancement to contribute to the history of rock culture was television. In 1950s it experienced essential growth and was revolutionized by the presentation of color broadcasts. Color television without any doubt brought a huge gamma of new impressions to the viewers, and by 1955 half of the households in the United States had applied a TV set. Before creating something original, television air was mostly filled by programs modified from radio shows. Consequently, music shows were also among the most called-for, and rock star producers actively used this opportunity. Now the fans could not only here their favorite bands and singers in records, but they could also watch them with their own eyes. Television broadcasted concerts and gradually video clips were rising; musicians were giving interviews and millions of fans throughout the country could stick their noses to the screens and enjoy show programs as well as an imitation of personal communication wit h stars. It is obvious that color television provided much more realistic image. Television industry, on the one hand, became a home for rock to live in and to address from, and on the other hand it soon provided the songs with a new context. Television was a solid and inherent part of popular culture, while rock, by its mission, was to oppose to popular culture and found a new shooting mark for its sharp sting. Television together with radio made rock n roll a groundbreaking body in mass communication. Since the rise of color television, it was no more music only. Now it became a new media of manipulating peoples conscience and tastes. TV presented a new method for encoding and decoding information, developing absolutely new system of motivations and preferences. Inexperienced audience was ready to believe everything coming from the screens of their home TV sets, and their unprecedented interest gave birth to demanded activity (Miller, ed. 36). The more active they were, the more p opular were those who managed to get to the back side of the set. Rock became the music of performance, not only listening. All in all, there was a great number of factors defining and enhancing the fate of rock n roll culture. Apart from some inner reasons, advancements n technologies were among the most shifting stones that assisted rock and roll to spread throughout the world. All points of the research considered, it is easy to make a conclusion that the effect of technology progress on rock culture was truly overwhelming and did revolutionize the way we produce, distribute and consume music.

Hidden Emotions to Be Revealed The novel follows Clarissa Dalloway, the main character and other characters throughout their lives in 1923. The narrator of the book goes into the character’s mind and shows their emotion through each event that occurs throughout the day. The characters are trying to find a way to express their need for communication but also to demonstrate their need for privacy. Mrs. Dalloway, by Virginia Woolf, expresses the idea of hidden emotion being the sole benefactor of the actions taken by the characters aiming to instability within them. Clarissa Dalloway is the main character and the protagonist of the book Mrs. Dalloway. Clarissa Dalloway provides a unique example of the difficulty there is in finding happiness in the world. (Lauren Klein) She is 50 years old; she displays her energy and time into being a high society hostess by throwing lots of parties. Since she throws parties this is her way to convey her pathway to communication and an attempt to draw people together. In the beginning of the novel, we see Clarissa as an upper class woman who seems to be a bit shallow. (Lauren Klein) she is a bit shallow because she is the wife of a government worker and looks down on a person who doesn’t follow the social standards that are set for them. Deep down inside of her, she doesn’t feel attractive to the world because she cares a lot about what other people have to think about her. On the outside she shows that she happy and talkative but inside she is lacking confidence. She is always questioning and wondering if she is truly happy about the way that her life is. â€Å"It was, she thought, partly their clothes, partly being taken out of their ordinary ways, partly the background, it was possible to say thing... ...bservation that killing oneself is cowardly, that Septimus had fought and was brave, but that her husband was no longer Septimus– is given the task of constantly pointing things out to Septimus in an attempt to connect him to the outside world, but to no avail.† (Lauren Klein). She believes her husband has gone for the worst and he is not the Septimus that she first met and the one she decided to marry. After all in Mrs. Dalloway each character has their own flaws that they are trying to get through and reveal their hidden emotions. â€Å"They went in and out of each other’s minds without any effort.† (Woolf) this quote represents my whole paper and exactly their hidden emotions. Mrs. Dalloway, by Virginia Woolf, expresses the idea of hidden emotion being the sole benefactor of the actions taken by the character to stabilize their lives and feelings throughout the book.

Bruce and Clark Essay -- essays papers

Bruce and Clark To the ordinary citizen of any given suburb, town, or city the names Bruce and Clark do not particularly stand out to be special or significant. If one was to ask an ordinary citizen if he or she had heard of Batman and or Superman, one could bet that those names would be labeled as special and significant. Bruce Wayne and Clark Kent otherwise known as Batman and Superman have lived in America's comic books, movies, cartoons and hearts for well over fifty years. Protecting the streets of Gotham City and Metropolis, these crime fighters have given a great deal to humanity, and although they have many similarities, their childhood and upbringing are quite different. Batman and Superman have basic hero similarities. Costumes, secret identities, and love for cheesecake . . ., ok so not the cheesecake, are obtained by both. Looking a little deeper than surface information, both heroes' parents passed away when they were very young. Batman's parents died by the hand of a petty thief in a robbery turned sour, while Superman's ferternal parents blew up on their home planet Krypton. Another event shared by the soldiers of justice is the fact that both were influenced by their father to become crime fighters. Clark Kent's father asked him to use his powers and gifts for good. Bruce Wayne's father was murdered and Bruce felt guilty for not preventing it, therefore creating Batman to help prevent it from happening to anyone else. In addition to the other similarities both characters are part of the same comic brand name, DC Comics. This allowed the heroes to interact and be on the same team in one particular scenario, Justice League of America was the name of that organization. The Justice league was... ...nstead of being born with powers, revenge gave birth in Bruce's heart and diligent pursuit of expertise haunted his every dream. Therefore, Bruce is a self-made prevention vigilante for Gotham City. Superman and Batman, they serve they same purpose and fight for the same outcome, good over evil. But the only thing similar about Clark Kent and Bruce Wayne's childhood is that they were both young. The fact that people are most influenced when they are young and start to obtain their personalities around the age of five suggests that if different circumstances had derived from either situation that Metropolis would have never had a Superman and Gotham City would be a crime ridden vicinity without the Dark Knight. I am glad that the world has the opportunity to partake in the adventures of these DC Comic hereos. Their stories proves that any can go from zero to hero.

How does television cause violent behavior? Essay

How does television cause violent behavior? Good question. All people watch TV but only some of them use violent behavior. Television is an idol of the modern days. Watching television is an experience shared by the vast majority of children and adults, men and women, wealthy and poor people. It is convenient, inexpensive, available and attractive. Television can entertain us and can teach us some useful or useless things. Too frequently it is used even as a substitute for other activities. Activities like violence. For the most the violence is ugly, unattractive and †¦ forbidden thing. We can see it in the streets, back alleys, school, and even at home. But the main source of violence in our life is television. Children are the most vulnerable group for influence of the television violence. Seeing a lot of violence on television can lead them to behave aggressively. I read story about a 16-year-old boy who broke into a cellar in the city of New York. When the police caught him and asked him why he was wearing gloves he replied that he had learned to do so to not leave fingerprints and that he discovered this on television. But television violence does not affect only child’s youth; it can also affect his or her adulthood. This can force the child into a kind of premature maturity. As the child matures into an adult, he can become bewildered; have a greater distrust towards others, a superficial approach to adult problems, and even an unwillingness to become an adult. In Alabama, a nine-year-old boy received a bad report card from his teacher. He suggested sending the teacher poisoned candy as revenge as he had seen on television the night before. This young Borja probable will have problems with conflict management in the future. It will be easier for him to think about poisonous candy or another Kunststueck than to face the conflict and find wise solution (e.g. learn subject better). I am wondered why people find the violence that they can see on television more attractive than the violence on the streets. Probably when we sit near the television screen, in safety and comfort, our curiosity make us to look to the unattractive features of human relationship? We know that those lakes of blood, explosions, masculine domination or brutal words are far from our sweat home. But children don’t always realize that this is not the way thing are handled in real life. They come to expect it, and when they don’t see it the world becomes bland and in need of violence. The children then can create the violence that their mind craves. A seven-year-old Californian boy sprinkled ground-up glass into the lamb stew the family was to eat for dinner. When asked why he did it he replied that he wanted to see if the results would be the same in real life as they were on television.Television sends not only messages about exciting world of adventures and violence. It offers role model which child can try to put on. Children find the violent characters on television fun to imitate. This could be a problem for children in the big cities, where aggressive behavior is more acceptable. I do not feel sure that there are no gender peculiarities of television violence impact on the youth. Probably, boys are more sensitive to this impact. They see heroes who become their role models. They accept that it is cool to carry an automatic weapon and use it to knock off the bad guys. I never had Kalashnikov or M-16 automatic rifle but I saw awesome movie – Bowling for Colombine†¦Fortunately, there were developed programs for parents’ and children education to prevent unfavorable effects of watching violence television. We advise to limit television viewing time to 1 to 2 hours each day, to control content of TV shows and movies watching by children, to discuss with children issues of violent behavior and ways how to solve problems without violence. I propose not palliative but more radical preventive measure – do not watch TV at all. Today American children spend near television more time than they spend in school. They watch cartoons, movies and shows with the violence. Children should stop it and read more books. Without violence, of course.
