Nuclear Weapons A major problem concerning the world today is the disposal of nuclear weapons. With the Cold War, we have seen a massive build up of nuclear weapons, and no, that we are no longer in a state of global warfare, what is to be done with them? As a result of the build-up in nuclear weapons during the cold war the world is now facing major environmental problems trying to deactivate them, and in addition major debate are occurring on the policies of disarmament and deterrence as solut

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
Animal Experimentation
Animal Experimentation
Animal Experimentation Introduction Animal experimentation has been a part of biomedical and behavioral research for several millennia; experiments with animals were conducted in Greece over 2,000 years ago. Many advances in medicine and in the understanding of how organisms function have been the direct result of animal experimentation. Concern over the welfare of laboratory animals is also not new, as reflected in the activities of various animal welfare and antivivisectionist groups dating ba
Integrated Pest Management
Integrated Pest Management
Integrated Pest Management Integrated pest management (IPM) is a recently developed technology for pest control that is aimed at achieving the desired control while reducing the use of pesticides. To accomplish this, various combinations of chemical, biological, and physical controls are employed. In the past, pesticides were all too often applied routinely whether needed or not. With IPM, pest populations as well as beneficial parasite and predator populations are monitored to determine whether

An Ecosystem's Disturbance by a Pollutant Paul Cordova L. Lehr December 11, 1995 Freedman defines a pollutant as the occurrence of toxic substances or energy in a larger quality then the ecological communities or particular species can tolerate without suffering measurable detriment (Freeman, 562). Although the effects of a pollutant on an organism vary depending on the dose and duration (how long administered). The impact can be one of sublethality to lethality, all dependent upon the factor

Purple Loosestrife
Purple Loosestrife The scene is breathtakingly beautiful, a thick brush of purple flowers blankets Canada's wetlands. This blanket silences the expected sounds of the wetland environment, birds chirping, ducks splashing, insects buzzing and animals thriving. This unnatural silence is disturbing, the favourite flowers that used to litter this landscape are no longer visible, the water that used to ripple continuously is perfectly still. The wetland is dead, except for this overpowering, hardy pur
The Atmospheric Ozone Layer
The Atmospheric Ozone Layer
The Atmospheric Ozone Layer The stratospheric ozone layer exists at altitudes between about 10 and 40km depending on latitude, just above the tropopause. Its existence is crucial for life on earth as we know it, because the ozone layer controls the absorption of a portion of the deadly ultraviolet (UV) rays from the sun. UV-A rays, including wavelengths between 320 and 400nm, are not affected by ozone. UV-C rays between 200 and 280nm, are absorbed by the other atmospheric constituents besides oz

What makes plants grow Several people have puzzled over this question
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

In the 1970s natural hazards were an important subject of topical stud
In the 1970’s, natural hazards were an important subject of topical study, as the nature of their impact on human populations and what they valued was increasing in frequency at quite a rapid rate (Burton, Kates, White, 1978). During the 75 years after 1900 the population of the earth increased by a staggering 2.25 billion people. People who needed land on which to live and work. As the population rose people were dispersed in more places and in larger numbers than before. The predominant movem

The sea is the most obvious feature of the earth's surface. Approximately seventy percent of this surface is covered by water, in one way or another. Beneath this water are the familiar sands of the beaches, bottoms of bays, and the inshore ocean. Farther offshore this water covers an amazing submarine topography of underwater canyons, trenches, mountains, and plains. Unlike the continents, which are physically separated from one another, the oceans are continuous and interconnected. Since the

On August 2nd, 1990 Iraq military forces invaded and occupied Kuwait. The order was given by Iraq’s dictator-president Saddam Hussein. His aim was apparently to take control Kuwait’s oil reserves (despite its small size Kuwait is a huge oil producer; it has about 10 per cent of the world’s oil reserves). Iraq accused Kuwait of breaking agreements that limit oil production in the Middle East. According to Saddam Hussein, this brought down world oil prices severely and caused financial loss of bi

Combinatorial Chemistry And New Drugs The body fights disease by generating antibodies that bind to invading organisms. The body can make different antibodies by shuffling and reshuffling their constituent parts, but it can't make a special antibody each time it is faced with a new pathogen. So it uses only the antibodies that will work best and makes more of them. In the past few years, chemists have begun to follow this method to develop new drugs. Instead of looking for signs of a desired ac

Was a military struggle fought principally in Kuwait and Iraq during January and February 1991. The crisis began in August 1990, when Iraq, led by President Saddam Hussein, invaded and annexed Kuwait. Between August and November the United Nations Security Council passed a series of resolutions that culminated in the demand that Iraq withdraw unconditionally from Kuwait by January 15, 1991. By that time, some 500,000 allied ground, air, and naval forces—chiefly from the United States, Saudi Ara

THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Changes in altitude have a profound effect on the human body. The body attempts to maintain a state of homeostasis or balance to ensure the optimal operating environment for its complex chemical systems. Any change from this homeostasis is a change away from the optimal operating environment. The body attempts to correct this imbalance. One such imbalance is the effect of increasing altitude on the body's ability to provide adequate oxygen to be utiliz

They say a woman's right to make that choice freely is fundamental. While, an equally passionate pro-life movement has proclaimed that abortion is the ultimate human rights issue. Each side is deeply convinced of the rightness and importance of its cause. Voices are raised, often heatedly; debates and demonstrations continue. Too often overl

Why do people develop fears and phobias? There are many factors that contribute to the development and maintenance of phobias. Firstly we must discuss what is known about the origins of natural fear before considering clinical evidence on the genesis of abnormal phobias. Fear is a very ancient and universal emotion in man. It can be defined as the sensation felt when you are in danger, a feeling that something bad is about to happen. When it is not justified by the presence of real danger or thr
