The Life of LOUIS PASTEUR
The Life of LOUIS PASTEUR
The Life of LOUIS PASTEUR Louis Pasteur was born on December 27, 1822, in Dôle, a small town in France. He grew in a humble family and his father was a tanner. He graduated in 1840 from the College of Arts at Besancon and entered the prestigious Ecole Namale Supervieure, Paris, to work for his doctorate degree. He chose for his studies the then obscure science of crystallography, which was to have a great influence on his career. Pasteur entered the scientific world as a professor of physics at

Theodor Seuss Geisel
Theodor Seuss Geisel I like nonsense, it wakes up the brain cells. Fantasy is a necessary ingredient in living, it\'s a way of looking at life through the wrong end of a telescope. Which is what I do, and that enables you to laugh at life\'s realities. Dr. Seuss Theodor Seuss Geisel was born in Springfield Massachusetts in 1904. He went to Dartmouth College and Oxford University as an English Literature student. He started writing for the Jack\'o Lantern the Dartmouth College humor magazine,
The Bay of Pigs Invasion
The Bay of Pigs Invasion
The Bay of Pigs Invasion The story of the failed invasion of Cuba at the Bay of Pigs is one of mismanagement, overconfidence, and lack of security. The blame for the failure of the operation falls directly in the lap of the Central Intelligence Agency and a young president and his advisors. The fall out from the invasion caused a rise in tension between the two great superpowers and ironically 34 years after the event, the person that the invasion meant to topple, Fidel Castro, is still in power

Auschwitz
Auschwitz Auschwitz began as a barracks camp in the town of Oswiecim, for the polish army in the early 1930\'s. Germany then captured Poland and needed another location for Polish political prisoners. In 1940, the German SS sent a commission to Oswiecim to see if the barracks there could be used. The first inspection reported that it could not be used, however, a later inspection stated that after a few minor changes it would be useable. On May 4, 1940 Rudolf Hoss officially established it as a

THE BUBONIC PLAGUE
THE BUBONIC PLAGUE Rana Kundu Introduction Plague, was a term that was applied in the Middle Ages to all fatal epidemic diseases, but now it is only applied to an acute, infectious, contagious disease of rodents and humans, caused by a short, thin, gram-negative bacillus. In humans, plague occurs in three forms: bubonic plague, pneumonic plague, and septicemic plague. The best known form is the bubonic plague and it is named after buboes, or enlarged, inflamed lymph nodes, which are characteris

World War I Powers During World War I many different types of weapons were utilized by both the Allied and Central powers. Some were variations on older models of weaponry, and others were totally new inventions created to aid in the wartime effort. Most of the new weapons were used as killing machines in trench warfare, which was practiced during World War I, while others were employed as tools of espionage, scouting land areas, or air and sea warfare. Communication also played a major role in

From the Roots of Metal-Workings The impact of metalworking traditions on the ornamentation of early insular manuscripts cannot be more clear in than in the carpet pages of the Lindisfarne Gospels. This is particularly true when viewing the cross-carpet page introducing Saint Mark\'s Gospel, as shown on plate 51 of The Lindisfarne Gospels, and comparing that page with the metal-work pieces discovered at the Sutton Hoo ship burial site. In particular, it is in comparing the motifs and designs of

Mononucleosis
Mononucleosis Mononucleosis, also known as Mono, is an illness caused by an infection with a virus. The virus, The Epstein-Barr Virus (EBV) is usually the cause of Mono. Other infectious viruses, like cytomegalovirus (CMV) can also produce illnesses like Mono. Most of the people who get Mono are adolescents and young adults. In developed nations, the majority of the people has been exposed to the Epstein- Barr virus by the age of 18. That means that many adults have had infections as children

Resuscitation from Severe Hemorrhage
Resuscitation from Severe Hemorrhage The resuscitation after severe hemorrhage is a very delicate process which involves many biological factors with a very small time window. To successfully revive a victim of severe exsanguination, one must work quickly within the golden hour time limit. In this time period, there are various trauma that must be avoided; cardiac arrest, hypotension, hemorrhagic shock, and hypothermia to name a few. This article encompasses the current technology for resuscit

Creationism vs. Evolution In my short life on this planet I have come to question things that many take upon blind faith. We all know that we must some day die; yet we continuously deny the forces at work inside ourselves, which want to search out the answers of what may or may not come after. It is far easier for humanity to accept that they will go to a safe haven and be rewarded for their lives with pleasures and fantasies of an unfathomable scale than to question the existence of a supposed

Cloning
Cloning The new breakthrough of cloning is a great advance in biotechnology. The use of cloning can be both beneficial and harmful to society. There are many reasonable ways to use the methods of cloning. For instance, the use for medical purposes can be helpful in cases such as producing animals with human body systems that could be used for transplanting organs. It can be a valuable asset to our society in that way. It can be harmful if it is opened for use in the general public because it cou

Some of the more well known dementing diseases include Alzheimer\'s disease (AD), multi-infarct dementia (MID), and Huntington\'s disease (HD). Throughout this essay the emphasis will be placed on AD (also known as dementia of the Alzheimer\'s type, and primary degenerative dementia), because statistically it is the

What makes plants grow? Several people have puzzle
What makes plants grow? Several people have puzzled over this question. There is no one single answer to this. Several factors contribute: Tropisms, environment, hormones, biological clocks, and even humans. We are trying to determine the effects of music on plants. It takes all these combined to have a plant that actually grows and a plant that is healthy and happy in its habitat. Hormones Hormones contribute greatly to the growth of plants. Hormones such as auxins, gibberellins, cytokinins, a

Insects have sensors (force-sensitive organs) conc
Insects have sensors (force-sensitive organs) concentrated in areas near joints, tips of the legs, and near exoskeletal sites attached to muscle tendons. These sensors act as strain gauges to detect compression of the exoskeleton. Using this information, insects recognize environments, regulate walking movements, and astonishingly remember stepping patterns and location. Through memory experiments, scientists see that a spider memorizes its own previous walking movements to backtrack to a fly

Human Immunodeficiency Virus The topic of this paper is the human immunodeficiency virus, HIV, and whether or not mutations undergone by the virus allow it to survive in the immune system. The cost of treating all persons with AIDS in 1993 in the United States was $7.8 billion, and it is estimated that 20,000 new cases of AIDS are reported every 3 months to the CDC. This question dealing with how HIV survives in the immune system is of critical importance, not only in the search for a cure for t
Active Transport
Active Transport
Active Transport Since the cell membrane is somewhat permeable to sodium ions, simple diffusion would result in a net movement of sodium ions into the cell, until the concentrations on the two sides of the membrane became equal. Sodium actually does diffuse into the cell rather freely, but as fast as it does so, the cell actively pumps it out again, against the concentration difference. The mechanism by which the cell pumps the sodium ions out is called active transport. Active transport require

Cancer Introduction According to Mollet, cancer is the second leading cause of death in the United States. Estimates for 1982 indicate that 430,000 Americans will have died of some form of cancer. If national trends continue, some fifty-three million Americans now alive will contract cancer sometime during their lifetime. Of this inverse number, approximately one-half will die of cancer despite a medical effort to cure and prevent cancer (300). Although 45 percent of the detected cases of seriou

Since we are interested in the function of molecules. it helps to study their structure. One of the major classes of organic compounds found in cells are carbohydrates. These carbohydrate are made of carbon, hydrogen, and oxygen in a ratio of 1:2:1 respectively with a general formula of X(CH2O)n. When the ca

They look alike, think alike, and even have the same genetic makeup. No, this isn\'t an episode of Star Trek, this is reality. This is the new world of cloning, and thanks to a 7-month-old sheep named Dolly, a new science has been born. As with every new science, there are those who believe in it, and those who op

The Digestive Systems The digestive systems works on nutrients taken from the environment, breaking them down into simpler products, and then absorbing the products together with water and salts so they can be used in metabolism. The individuals of all species contain many different protiens or carbohydrates in the cell walls of bacteria, chitin in the external skeletons of arthropods, and so on and foreign proteins or carbohydrates are rarely incorporated unchanged. They are usually first broke

The Ebola Virus
The Ebola Virus A virus is an ultramicroscopic infectious organism that, having no independent metabolic activity, can replicate only within a cell of another host organism. A virus consists of a core of nucleic acid, either RNA or DNA, surrounded by a coating of antigenic protein and sometimes a lipid layer surrounds it as well. The virus provides the genetic code for replication, and the host cell provides the necessary energy and raw materials. There are more than 200 viruses that are know to

He published a book in 1924 called Behaviorism. Jakob von Uexkull and O. Heinroth started a school that taught about animal behavior. There are two categories of animal behavior: genetically determined or environmentally determined. Animal behavior is the different ways that animals do different things, such as hunt

The rapid development of the technology for cloning has led to moral debates around the world on whether or not to ban creating human clones. With the advancement of clone technology two states, California and Michigan have already banned the cloning of humans.

Human Cloning
Human Cloning Biological Aspects True human cloning involves taking a somatic cell from a person and removing its nucleus. Then the nucleus of a fertilized egg cell is removed and placed in the somatic cell. This is impossible in humans right now because the somatic cells are specialized and there are many genes that have been switched off in them that we do not know how to turn them back on. This was done with frogs however. The eggs were implanted with the nuclei from the intestinal lining of

Aplastic Anemia Aplastic anemia is a disease of the bone marrow— the organ that produces the body\'s blood cells. Approximately two thousand people in the U.S. are diagnosed each year with aplastic anemia. The symptoms of aplastic anemia are fatigue, bruising, infections, and weakness. Although these symptoms are much like those associated with leukemia, aplastic anemia is not a form of cancer. In patients with aplastic anemia the bone marrow stops producing, or produces too few red blood cells,

It stands to reason: Take a group of people, strip them of possessions and privacy, expose them to constant threats of violence, overcrowd their cell- block, deprive them of meaningful work, and the result is an embittered underclass more intent on getting even with society than contributing to it. Prisons take the nonviolent offender and make him live by violence. They take the nonviolent offender and ma

Born in 1887, Padre Pio is not yet canonized. Francesco, named in honor of St. Francis of Assisi, was one of eight children of Grazio and Maria Forgione. Francesco was very devout even as a child, and at an early age felt drawn to the priesthood. He became a Capuchin novice at the age of sixteen and received the “habit” in 1902. Francesco was ordained to the priesthood in 1910 after seven years of study and became known as Padre Pio. On September 20, 1918, Padre Pio was kneeling in front of a la

Abortion: Life or Death, Who chooses? During the past quarter century, abortion has joined race and war as one of the most debatable subject of controversy in the United States. It discusses human interaction where ethics, emotions and law come together. Abortion poses a moral, social and medical dilemma that faces many individuals to create a emotional and violent atmosphere. There are many points of view toward abortion but the only two fine distinctions are pro-choice and pro-life. A pro-
