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 approxim...

- Kombucha Fungus
This article from the World Wide Web is about the Kombucha fungus, what some call the miracle
mushroom. This widely hyped ailment-for-anything are also known as Manchurian mushrooms and Indo-
Japanese tea fungus. There is so much information about Kombucha that when I did a web search on it
over 100 web sites were devoted to this strange fungus I had never heard of.
I decided to look further as see what all this hype is about. Kombucha is a yeast culture
- College Degrees
Many adults who graduate from high school immediately enter careers that do not require a college degree. Indeed, the majority of the adult population of the United States of America does not have college degrees. And the lack of degree is not a stigma.
Vocations usually do not require degrees. Certainly the many trade vocations in the building industry do not require college degrees, but instead either vocational training, on-the-job training, and combinati...
- Skin Cancer
Every hour one American is killed by skin cancer and every thirty seconds one American gets skin cancer.
Cancer is a deadly disease that alters the DNA of a skin cell and causes it to reproduce at a rapid pace. This
overproduction of cells can be harmful and in many cases deadly. Out of these cancers the most common
is Basal cell carcinoma. Many steps have been made in the treatment of Basal Cell Carcinoma, some have
been very successful and some not.
The cells that have th...
- Neutrinos And Gamma Rays
Neutrinos and Gamma Rays
Emission of a beta particle produces an energy change in the nucleus of an atom. The energy change that is observed, however, does not add up to satisfy the Law of Conservation of energy. The conservation law can be balanced if another particle, called the neutrino is part of this process. In the time it takes to read just this sentence, more than a billion of them will have passed unnoticed through the reader's body. Neutrinos may account for an appreciable porti...
- The Greenhouse Effect
The Greenhouse Effect
The greenhouse effect is an increase in the atmospheric temperature caused
by increasing amounts of greenhouse gases. These gases act as a heat blanket
insulating the Earth's surface absorbing and trapping heat radiation which normally
escapes from the earth. They include carbon dioxide, water vapor, methane,
nitrous oxide, CFC's, and other halocarbons.
The earth's atmosphere goes through two processes constantly. Global cooling
is the first process. This process uses t...

- Trace Evidence
Trace evidence is very important in forensic investigations. This category of evidence encompasses many
diverse types of microscopic materials as well as some examples that are easily visible to the naked eye.
The subject is broad and diverse because of the number of different types of evidence that are commonly
encountered. Trace evidence can be thought of as evidence occuring in sizes so small that it can be
transferred or exchanged between two surfaces without being notice...
Notes on the lithosphere- (rock sphere) Upper most part is crust of earth. Compiled of rocks of outer crust. Outermost shell. Upper part- rocks we see at and near the earths surface. Crust is 5 to 10 km thick under most oceans and 24 to 60 km thick under the continents. The lithosphere under the crust is solid, dense material. (more dense than surface materials). Lithosphere 100-200 km. Notes on the aesthenosphere- zone beneath the lithosphere. Thick like tar. Weak b...
