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

Environmental pollution concerns come to forefront Reports that the state finds El Dorado Irrigation District\'s drinking water system primitive, outdated and an avenue for hazardous pollutants sent El Dorado County residents scrambling for more information Wednesday. The message that pregnant, elderly and sick residents should boil their water or buy it bottled was buried in fine print in the 28,000 notices mailed in September to EID customers. Dozens of residents called EID offices Wednesday a

The Veterinary Profession When the first man set foot on this earth he longed for companionship. He wanted some one to keep him company, help him hunt and most of all, be a friend. Since that first step, when man domesticated animals, pets have been a growing part of many people’s lives. It is estimated that over seventy-eight percent of Americans have some type of pet, ranging from a common dog to an exotic snake, sharing their home with them (Barns 1). Just like humans, animals get sick and n
The Black Plague
The Black Plague
The Black Plague : From the early fourteenth to late seventeenth century, Europe was decimated by one of the most horrifying pestilence\'s human kind has ever known(Coulton 493). The killer\'s name was later to be recognized by the detrimental consummation it had seized upon a person\'s life. It was known as the Black Plague. This terrible epidemic exhausted small towns across Europe, including the British Isles, brutally killing an incredulous amount of people. The disease had wiped out entire

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

AIDS: Is it a Modern Plague? Donna Kundu In some parts of the world there are still wars being fought and dictators in power. There are societies which consider themselves at the peak of evolution and progress. They are able to create state of the art automobiles, luxurious homes, efficient and organized industries, complex computerized machinery and atomic weapons. Many societies are governed by a democratic system which herald a belief in freedom. All societies, regardless of their political

Pollution Pollution is the introduction of harmful substances or products into the environment. It is a major problem in America and as well as the world. Pollution not only damages the environment, but damages us also. It has cause many problems ranging from lung cancer to the greenhouse effect. It is all among us and but we continue to live in our own filth. What is the reason behind this flawed logic? In this paper I will examine the problems and solutions for this issue.

I am your usual plant cell. There are trillions of my kind on all plants, grass, and trees. My breed ranges from ten to a hundred micrometers. I am approximately twenty micrometers since I dwell in grass. My organelles stretch out to one to ten micrometers. If you are asking what I really do and how I live, I am going to answer them in this paper. First off, any cells requires a structure, metabolism, energy, nutrients, waste, and communication. I am more complex than most other cells. Bacteria

Suddenly many thoughts come into your mind, you wonder how did the bug get there and was it dead or alive. Is it harmful or carry a disease. You ask yourself did the bug come from the United States or another country and where was your snack made? As all these questions come into your head, you wonder who
Antibiotic Resistance In Bacteria
Antibiotic Resistance In Bacteria
Antibiotic Resistance In Bacteria For about 50 years, antibiotics have been the answer to many bacterial infections. Antibiotics are chemical substances that are secreted by living things. Doctors prescribed these medicines to cure many diseases. During World War II, it treated one of the biggest killers during wartime - infected wounds. It was the beginning of the antibiotic era. But just when antibiotics were being mass produced, bacteria started to evolve and became resistant to these medicin

Bacteria are often maligned as the causes of human and animal disease (like this one, Leptospira, which causes serious disease in livestock). However, certain bacteria, the actinomycetes, produce antibiotics such as streptomycin and nocardicin; others live symbiotically in the guts of animals (including humans) or elsewhere in their bodies, or on the roots of certain plants, converting nitrogen into a usable form. Bacteria put the tang in yogurt and the sour in sourdough bread; bacteria help to
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
The Digestive Systems
The Digestive Systems
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
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

Forensic Science: Proper Crime Scene Techniques. The word Forensic is derived from the Latin forensus, meaning of the forum.1 In ancient Rome, the forum was where governmental debates were held, but it was also where trials were held -- the court house. From that, forensic science has come to mean the application of the natural and physical science to the resolution of matters within a legal context2. Forensic Science can be viewed as a tripartite structure consisting of 1. Collection: which

Concepts of Lifetime Fitness September 1, 1997 Homeostasis is the state of equilibrium in which the internal environment of the human body remains relatively constant. Two excellent examples of homeostasis are how the body maintains a constant temperature and blood pressure during strenuous physical activity or exercise. Although there are many other activities in the body that display homeostasis, I will only discuss these two. Temperature in the human body is usually kept at approximately 37 d
Nitrogen
Nitrogen
Nitrogen Nitrogen, symbol N, gaseous element that makes up the largest portion of the earth\'s atmosphere. The atomic number of nitrogen is 7. Nitrogen is in group 15 (or Va) of the periodic table. Nitrogen was discovered by the British physician Daniel Rutherford in 1772 and recognized as an elemental gas by the French chemist, Antoine Laurent Lavoiser about 1776. Nitrogen is a colorless, odorless tasteless, nontoxic gas. It can be condensed into a colorless liquid, which can be compressed into

Nutritional Facts The first nutritional fact most Americans learn is that iron builds strong and healthy bodies.1 The beef lobby, cereal manufacturers, bread makers, and drug companies have bombarded the public with iron being the cure-all for fatigue and iron-poor blood. People have been mislead by drug companies pushing iron supplements and by old-fashioned ideas about iron, the magical nutrient of strength. Even the cartoons of the past pushed iron as the secret ingredient in Popeye\'s sp

The Plant Cell
The Plant Cell Cell Wall Size: Around 1µ Basic Function: * Hold the shape of the cell. * Strengthen the cell. Covering the cell membrane of the plant cell, there is the cell wall. The cell wall is composed of two layers of rigid, hard cellulose embedded in compounds like pectin and lignin. Pores in the cell wall allow molecules to pass through. The cell wall has two parts. The primary cell wall is formed during the growth of the cell. After the cell has stopped growing, a secondary cell wall for

They have always been very important to people, not only for food, but also for clothing, weapons, tools, dyes, medicines, shelter and a great many other purposes. Both humans and animals benefit from plants. We eat many different types of plants such as fruits and vegetables. We also use plants for our herbs. Plants are also used to manufacture many different produ
Aplastic Anemia
Aplastic Anemia
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,
