.... simple devices only capable of fixed-rate stimulation of a single chamber of the heart to more sophisticated "implanted computers" that medical personnel can interrogate and reprogram from outside the patient's body. These refinements have allowed for more physiologic pacing with maintenance of atrioventricular synchrony and cardiac output. There are various types of available today that can be surgically implanted to treat specific arryhythmic disorders in the heart. Abnormal rhythms in the heart are one of the most frequent causes of heart malfunction, and in most cases n .....

.... the public's biggest fears, meltdowns and contaminations, and make them into "events" and "infiltrations." This use of doublespeak is misleading to the public and may make them believe that a major accident hasn't happened, or the accident was a normal event or minor incident. In 1979 a valve in the Three Mile Island stuck open, allowing coolant, an important part of the plant, to escape from the reactor. An installed emergency system did its job and supplied the reactor with necessary coolant, but the system was shot off for a few hours due to employee error. Corrective a .....

.... Roots anchor the plant into the ground and they also gather minerals and water from the ground. Roots usually grow under ground and downward. Roots have tiny “hairs” which increase the surface of the roots, which results in more gathering of minerals and water. Stems are usually above ground, grow upward, and usually have leaves. Plants that do not have leaves generally use the stem as the photosynthetic surface, like cacti. Leaves are still the most common photosynthetic surface on plants, though. Leaves absorb carbon dioxide and release oxygen. Some leaves of p .....

.... skyscrapers and condominiums wipe out our decreasing rainforests. This drudges wildlife from its natural home and into the havoc that is ours. Millions of acres of beautiful land are destroyed daily to satisfy the needs of mankind. But has anyone contemplated the needs of our wildlife? When their homes are incinerated, where do they run for shelter? Where will wildlife obtain its food and oxygen if the sources are gone? Not much is done about our destructive ways, we sit back and let money and greed take power. The solution is just a whisper away. The preserved areas sh .....

.... rustles so slightly, no men, though men are the most refined of living beings, put so passing a stress upon their sacred whispers or their prayers. The leaves are hardly heard, but they are heard just so much that men also, who are destined at the end to grow glorious and to die, look up and hear them falling. There is an infinite amount of qualities of describing the leaves. The color is not a mere glory: it is intricate. If you take up one leaf, then you can see the sharp edge boundaries which are stained with a deep yellow-gold and are not defined. Nor do shape a .....

.... In laboratory studies, high doses are required to give weak hormone activity. These doses are not likely to be encountered in the environment. However the process of bioaccumulation can result in top-level predators such as humans to have contaminants at levels many million times greater than the environmental background levels (Guilette 1994). In field studies, toxicity caused by endocrine disruption has been associated with the presence of certain pollutants. Findings from such studies include: reproductive disruption in starfish due to PCBs, bird eggshell thinning due t .....

.... No one ever considered the fact that plutonium could be used for more constructive purposes such as: sources of energy or to keep a person's heart beating. We did begin to produce more plutonium but the majority of the substance was used towards our nuclear weapons programs. Along with reactors, sometimes comes a meltdown which can cause harmful effects if it isn't controlled quickly enough. After such instances as the Hanford, Washington reactor meltdown and the accident in the U.S.S.R. at the Chernobyl site, no one wanted to hear about the use of plutonium. The U .....
