DNA Code Only a small fraction of our total DNA makes us different from gorillas, chimpanzees and other primates. An even smaller fraction makes one person different from the next. It\'s these differences that forensic DNA experts use to identify people and determine the source of biological evidence such as blood or semen found at a crime scene. DNA testing is powerful, sensitive and effective in pointing to the guilty and absolving the innocent. To date, 67 convicted felons have been exonerat
DNA Profiling Genetic engineering has developed and blossomed at a frightening rate in the last decade. Originating as merely an area of interest for scientists, genetic engineering has now become an area of which all people should be somewhat knowledgeable. DNA profiling has many uses, both positive and negative, in our society. Aside from its usefulness in many legal investigations, DNA profiling can be used in the workplace to discriminate against employees whose profiles could pose a financ
Enzyme Catalase The enzyme catalase speeds up the decomposition of Hydrogen Peroxide into water and oxygen as shown here, 2H2O2-------------------*2H2O+O2. It is one of the fastest known enzymes and its turnover number is 6 million, which means the number of substrate molecules which one molecule of the enzyme turns to products per minute. This can be demonstrated by putting a piece of liver into a beaker of Hydrogen Peroxide, the fizzing shows a demonstration of the enzyme in action. AIM My ai
Ira Remsen Ira Remsen was born on February 10, 1846 in New York city. Even though he was born in the United States, he was educated in Germany. He received his M.D. at Columbia University in 1867 and he also earned a Ph.D. at the University of Munich and Göttingen in Germany. After receiving his degrees, Remsen began his investigation in pure chemistry at the University of Tübingen. It was in Germany and in Europe Remsen did most of his research. In 1876 he returned to the United States where h
Julius Robert Oppenheimer Julius Robert Oppenheimer was an American physicist and government adviser, who directed the development of the first atomic bombs. To scientists, he was not only the builder of the atomic bomb and a pioneer in atomic energy, but a master of many languages, a good conversationalist and a brilliant mathematician. He was also a writer, and an expert in both the history of architecture and the religions of the world. Oppenheimer, who was born in New York City on April 22,
Louis Pasteur PASTEUR, Louis (1822-95). The French chemist Louis Pasteur devoted his life to solving practical problems of industry, agriculture, and medicine. His discoveries have saved countless lives and created new wealth for the world. Among his discoveries are the pasteurization process and ways of preventing silkworm diseases, anthrax, chicken cholera, and rabies. *BR* Pasteur sought no profits from his discoveries, and he supported his family on his professor\'s salary or on a modest go
Polychlorinated Biphenyls Polychlorinated biphenyls are a family of man-made chemicals that contain two hundred and nine individual compounds with varying toxicity. Many different combinations are possible. In chemical terminology, "phenyl" denotes a ring structure of six carbon atoms attached to something else; "biphenyl" results when two such rings are attached to each other. Polychlorinated biphenyl (PCB) is any molecule having multiple chlorine atoms attached to the carbon atoms of a biphen
Spectrophotometery The purpose of this lab experiment is to understand the uses of spectrophotometry. This experiment concentrates on the uses of the spectrophotometer, and using this instrument to specifically determine the absorption spectrum of a cobalt chloride solution, a galactose solution, and to determine an unknown concentration of a galactose solution. Modern biologists frequently use the measurement of light absorption to determine concentration of chemicals. The technique is called
Vitamin C Amount Estimation By DCPIP Vitamin C (ascorbic acid) is a very important vitamin to the body. Vitamin C promotes healthy teeth and gums, helps absorption of iron, aids in maintenance of normal connective tissue, promotes wound healing, and helps boost the immune system. With vitamin C being such a useful substance to our bodies, finding good sources of vitamin C is important. Many people today rely on vitamin supplement tablets. But fruit juices, vitamin-supplemented drinks, or vitami
Interactive TV The Web and the Internet are the latest technologies to be harnessed by companies trying to develop interactive television. This paper reviews the efforts of technology companies and broadcasters to combine television and the Web in their products and activities, and how users are already using them both at home. It reviews some research on the way that TV and the PC/Internet are used at home, and suggests some way that the Web could be integrated with television use. Unlike earl
Matrix The Matrix (1999) is an extension of the existentialist motifs of the mid 20th Century set in the 23rd, for its obvious influences from the American Noir Style. This is apparent when looking at the five points of this existentialism. First, Thomas A. Anderson (Keanu Reeves), a.k.a. "Neo," is portrayed from the beginning of the film as a "normal Joe" who holds the potential of a world savior, yet without the narcissism. He does not have X-ray vision or the ability to leap tall buildings i
Artificial Intelligence Artificial Intelligence is based in the view that the only way to prove you know the mind\'s causal properties is to build it. In its purest form, AI research seeks to create an automaton possessing human intellectual capabilities and eventually, consciousness. There is no current theory of human consciousness which is widely accepted, yet AI pioneers like Hans Moravec enthusiastically postulate that in the next century, machines will either surpass human intelligence, o
Computer Industry In US Only once in a lifetime will a new invention come about to touch every aspect of our lives. Such a device that changes the way we work, live, and play is a special one, indeed. A machine that has done all this and more now exists in nearly every business in the U.S. and one out of every two households (Hall, 156). This incredible invention is the computer. The electronic computer has been around for over a half-century, but its ancestors have been around for 2000 years.
Computer Monitoring Computer Monitoring is most often intended to improve efficiency and effectiveness in the workplace, but with good intentions comes the opportunity for abuse by employers and employees alike. An example of both can be found in an article taken from The Futurist. Kristen Bell De Tienne\'s composition " Big Brother or Friendly Giant: Computer Monitoring in the 21st Century" is an exceptional observation as to what the future may hold for those people choosing to enter the tech
Computer Programmers Computer programmers held about 568,000 jobs in 1996. Programmers are employed in almost every industry but the largest amount is in the computer and data processing industry that includes companies that write and sell software. Allot of programmers can also be found working for companies that provide engineering and management services, manufacturers of computer and office equipment, financial institutions, insurance carriers, educational institutions, and government agenc
Domain System Server Domain System Network software generally needs a 32-bit Internet address in order to open a connection or send a datagram. However users prefer to deal with computer names rather than numbers. Thus there is a database that allows the software to look up a name and find the corresponding number. When the Internet was small, this was easy. Each system would have a file that listed all of the other systems, giving both their name and number. There are now too many computers fo
DOS And Unix Compare and Contrast Microsoft DOS with UNIX As is suggestive of its name, an operating system (OS) is a collection of programs that operate the personal computer (PC). Its primary purpose is to support programs that actually do the work one is interested in, and to allow competing programs to share the resources of the computer. However, the OS also controls the inner workings of the computer, acting as a traffic manager which controls the flow of data through the system and initi
Government Censorship Thesis: Government Censorship would damage the atmosphere of the freedom to express ideas on the Internet; therefore, government should not encourage censorship. Introduction I. In the Internet community, there is a large volume of technical terms. For this reason, it is first necessary to examine the terminology specific to Internet. 1.The internet is a world wide computer network. 1.Electronic mail (email), which is one component of the Internet, approximates person to p
Internet Censorship The Internet is a wonderful place of entertainment and education but like all places used by millions of people, it has some murky corners people would prefer children not to explore. In the physical world society as a whole conspires to protect children, but there are no social or physical constraints to Internet surfing. The Internet Censorship Bill of 1995, also known as the Exon/Coats Communications Decency Act, has been introduced in the U.S. Congress. It would make it
Internet History In 1973, the U.S. Defense Advanced Research Projects Agency (DARPA) initiated a research program to investigate techniques and technologies for interlinking packet networks of various kinds. The objective was to develop communication protocols which would allow networked computers to communicate transparently across multiple, linked packet networks. This was called the Internetting project and the system of networks which emerged from the research was known as the "Internet." T
Internet History In the early 1960\'s, the U.S. Department of Defense (DOD) became very concerned about the possible effects of nuclear attack on its computing facilities. As a result, it began to examine ways to connect their computers to each other and to weapons installations that were distributed all over the world. The DOD charged the Defense Advanced Research Projects Agency (now known as DARPA) to fund research that would lead to the creation of a worldwide network. The Advanced Research
Internet History The Internet was created in 1969 by scientists working for ARPA. ARPA stands for advanced research projects agency, and was formed to create a network of computers that could save information in the event of a nuclear attack. UCLA, Stanford Research Institute (SRI), UC Santa Barbara (UCSB), and the University of Utah in Salt Lake City were the first ARPANET locations. The ARPANET is what is now called the Internet. The plan was unprecedented: A professor at UCLA, and his small
Internet In Business World The history of the Internet traces its roots to the United States government. The original use of the information system was to maintain communication during the cold war, with the Soviet Union in 1969, by the Department of Defense, incase of a nuclear attack or a major catastrophe. The National Science foundation created the Internet based on the ARPAnet. The first mass connection was between the University of California Santa Barbara, Stanford Research Institute, th
Internet IT The internet offers a huge wealth of information both good and bad, unfortunately the vary nature of the internet makes policing this new domain practically impossible. The internet began as a small university network in the United States and has blossomed into a vast telecommunications network spanning the globe. Today the internet is ruled by no governing body and it is an open society for ideas to be developed and shared in. Unfortunately every society has its seedy underside and
Internet Tech The Internet links people together via computer terminals and telephone lines (and in some cases wireless radio connections) in a web of networks and shared software. This allows users to communicate with one another wherever they are in the "net." This Internet link began as the United States military project Agency Network Advanced Research (ARPANET) during the Vietnam War in 1969. It was developed by the United States Department of Defense’s (DOD) research people in conjunction
Internet Techs How to go about monitoring the vast new online world of the Internet. The Internet was developed initially for the Pentagon to transfer the curtail information. This essy is on the internet and how the world plans to deal with the new problems that it brings. To start a brief defination of what the internet is Before the Internet, there was ARPAnet (the predecessor of today’s Internet), created almost 25 years ago as an experimental network to support military research for the U.
Linux And Windows NT Forget the browser wars. This year\'s big nerd battle is the server shootout between Linux and Windows NT - and it\'s not just a bunch of geeks nit-picking. While both offer more affordable platforms for Web service than in the past, Linux and NT are polar opposites on almost every other level. They look different, run differently, support different software, and cost money in different places. So far though, most press coverage of the Linux-NT debate has focused on the com
Network And Internet Connections The Internet is a network of networks that interconnects computers around the world, supporting both business and residential users. In 1994, a multimedia Internet application known as the World Wide Web became popular. The higher bandwidth needs of this application have highlighted the limited Internet access speeds available to residential users. Even at 28.8 Kilobits per second (Kbps)—the fastest residential access commonly available at the time of this writi
Software Piracy Software piracy is defined as the illegal copying of software for commercial or personal gain. Software companies have tried many methods to prevent piracy, with varying degrees of success. Several agencies like the Software Publishers Association and the Business Software Alliance have been formed to combat both worldwide and domestic piracy. Software piracy is an unresolved, worldwide problem, costing millions of dollars in lost revenue. Software companies have used many diffe
Steve Wozniak At first I had began brainstorming trying to think of a subject for this paper. I had heard Mr. Perry speak of Apple computer and of Steve jobs. His rise to power and his fall from grace then his rebirth, like the phoenix from in myths and legends rising from his own ashes. However I didn’t know much about the subject. So I decided on the subject of Apple computers. Then the more I researched I found a more interesting subject. In the next few pages I am going to attempt to do jus
System Analyst Systems Analyst analyses, designs and implements the information gathered previously to a system, the final product which is a report of yearly sales, profits, etc. The first thing a Systems Analyst does is to interview the company which wants the report, (called the user) to find out what kind of report they want, format, etc. They must find whether the report is feasible or not, and to find out, they do an analysis of the project. To analyze the project, they must find out wher
Unix "UNIX was the first operating system designed to run on ‘dissimilar’ computers by converting most hardware specific commands in machine language into an independent programming language called ‘C,’" Jon Wolfe writes in the Nashville Business Journal. (Wolfe 29) UNIX was the basis of AT&T’s telephone system and the government’s wide area network system. Then it became the basis of communication between engineers and scientists, and eventually the basis of communication for everyone worldwid
Video Files Formats Invitro is defined as, "In glass, as in a test tube" (Taber’s cyclopedic dictionary,1993), hence with reference to invitro fertilization, the term "Test tube baby". The first ‘test tube baby’ was Louise Brown of England (Jonsen, A. R., 1996). Dr. Patrick Steptoe and Professor Robert Edwards combined an ovum from Mrs. Brown, and sperm from Mr. Brown cultured it in a petri dish, and reimplanted the now embryo into Mrs. Brown’s uterus (Jonsen, A. R.,1996). The result was the sam
Chinese Economics The social values and history have shaped and formed the economical developments and the current environment of business in the People\'s Republic of China. They have determined the patterns for negotiation and the Chinese perceptions of business, and their feelings towards westerners. The implicit and explicit rules that the Chinese society has on the development of businesses, and the economy in general, are very important issues for any person going into China to understand
Free Market Defense Ludwig von Mises: Defender of the Free Market Ludwig von Misis thoughts on human behavior, socialism, and money and credit have had a major impact on economic thought. He championed true free markets and is seen as a defender of liberty. Former President of the United States Ronald Reagan said "Ludwig von Mises was one of the greatest economic thinkers in the history of Western Civilization. Through his seminal works, he rekindled the flames of liberty. As a wise and kindly m
Hayek And Business Cycle Friedirch August von Hayek was born in Vienna on May 8, 1899 and died on March 23, 1992, in the city of Freiburg in Breisgan in Germany. Hayek was a central figure in 20th-century economics and he represented the Austrian tradition. After Hayek served military service, he became a student at the University of Vienna where he got his doctorate in law and political science. In 1923-4, Hayek visited New York and then returned to Vienna where he continued his work. Hayek be
Israel Foreign Policy Israel is located in the Middle East, along the eastern coastline of the Mediterranean Sea, bordered by Lebanon, Syria, Jordan and Egypt. It lies at the junction of three continents: Europe, Asia, and Africa. Long and narrow in shape the country is only 290 miles in length and 85 miles in width at its widest point. Israel is a country of immigrants. Since its creation in 1948, the population has increased seven-fold. Today, its over six million inhabitants represent many d
Karl Marx Human relationships have always been dynamic. Change and adaptability have gone hand in hand with the passage of time for human society. Systems have been developed to regulate, direct and control the resources of this society. The systems are referred to as governments and the resources as the populace or inhabitants and forces of production. A government must be dynamic in its nature reflecting the change in society. At times these systems have resisted the necessity to adapt with i
Nobel Prize Winners The theories of these five men: John C. Harsanyi, John Nash, Reinhard Selten, Robert W. Fogel, and Douglass C. North, made an abundant progress in the Economic Sciences in America and the economy. For these great accomplishments, these five were awarded the Noble Peace Prize in Economic Sciences in 1994(Harsanyi, Nash, Selten), and 1993(Forgel, North). The three economists who was awarded the Noble Peace Prize in 1994 for their excellent work and progress in game theory was
Nuclear Power Most of the world\'s electricity is generated by either thermal or hydroelectric power plants. Thermal power plants use fuel to boil water which makes steam. The steam turns turbines that generate electricity. Hydroelectric power plants use the great force of rushing water from a dam or a waterfall to turn the turbines. The majority of thermal power plants burn fossil fuels because thermal power plants are cheaper to maintain and have to meet less of the governments requirements c
Trade In Ancient Greece When we discuss the economics of the ancient world, we must be careful not to use the formal Economics which we employ in analyzing our own society, since Economics is a function of the way a society runs, not the set of rules under which a given society operates. We cannot remove ourselves from awareness of the economic disciplines which our schools teach, and even if we formally try to suspend Economics as a framework, we retain the image of the economic framework in o
Virginia Unemployment The economic situation differs from country to country, caused by difference in population, geography, monetary system, political situation and a lot of other factors. But even within one country there are always a number of regions that differ from one another by their economic performance. This situation is especially true for big countries like US. If the regions are too broadly defined, the economic diversity would be lost. If the regions are too narrowly defined, they
College Choosing Choosing a college during the final years of high school can be a long strenuous process, full of many lifelong decisions. These decisions can be broken down into six categories. The categories are cost, entrance requirements, location, living arrangements, unique programs, and extracurricular activities. The University of Missouri St. Louis and the University of Missouri, Columbia have some similarities yet many more differences. A major concern when deciding which college to
Dream School I am going to write my paper on my vision of the perfect school. In describing my dream school I will explain how it will operate, involve special education students and prepare students for life after high school. A strong site based administration is not only my preference, but is also the system that is most effective. I will first identify the individual positions of my dream school and then define their roles. I will call my school Dream High School. Dream High will have a tra
Education And Evolution Throughout recent history creationists and evolutionists have argued whether evolution should be a part of America\'s public education. Whether evolution is science fact, or science fiction. Evolution being a science based on statistics has some faults, although many concepts in science or math do. The process of learning about evolution is a necessary part of a well-rounded student\'s education due to the fact that it is a statistically proven science and removing it in
Good Student In education and in other fields of life, people are separated and grouped into"nice" sections. It has been going on for a long time, even before Plato defined his ideal society. The separating of the good and bad, intelligent and stupid, and high and low class will continue to be a part of who we are as a culture, because our educational structure requires students to learn the"basic skills." A problem arises because many people do not fit nicely into a box. I didn’t want to be in
Home And School Education What do George Washington, Thomas Edison and Theodore Roosevelt have in common besides fame? None of them joined school formally (Winger and Kantrowitz 6). In recent years, many have followed their example and started learning at home in the United States. The number of home schooled children has greatly increased over the past decade. Many have argued against home schooling while many others see no negative outcomes involved. Although homeschooling has no major benefi
Home Schooling It May Be The Best Thing for Your Child Home schooling... will it be beneficial or harmful to the student? Can the child fit in or perform normal social functions in the real world? Do the parents have certified credibility to educate? How well will the child adjust to everyday life? Do they interact normally with others of the same age? Can they function in an uncontrolled environment? All of these questions are quite legitimate and realistic. However, the real question to be an
Inclusion Within the past decades and a half considerable discussion has occurred regarding the most appropriate setting within which to provide education for students in special education. Although the change in the educational environment is significant for handicapped student the concepts of inclusion also bring up new issues for the regular education classroom teachers. The movement toward full inclusion of special education students in general education setting has brought special education
Learning Styles Throughout our lives, we are faced with many different learning experiences. Some of these experiences have made a better impact than others. We can attribute this to our learning style. A person’s learning style is the method through which they gain information about their environment. Research is going on all over the world to help explain learning styles. As teachers, it is our responsibility to learn about these different learning styles so that we can appeal to every type o
