Over eighty-five percent of the energy that powers the planet is derived from the burning of fossil fuels (Information 16). Fossil fuels contain impurities and these “impurities such as sulfur also burn and produce potentially dangerous oxides” which are released into the air (Burning www 1). Releasing these oxides into the ...

The Luminescence Of Black Light

... characteristic of giving off light or radiant energy when ultra-violet light is allowed to fall upon them. This is called luminescence. In most cases, the wave length of the light radiated is longer than that of the ultra-violet excitation but a few exceptions have been found. The quantum theory attempts to explain this property by contending that a certain outside excitation causes an electron to jump from one orbit to another. It is then in an unstable environment causing it to fall back into its original orbit. This process releas ...

Hepatitis

... contagious agent.1 This particular living entity was so small that it readily passed through a porcelain filter. With the invention of the electron microscope by Ernst Ruska, the virus' true anatomy was first time visible to us in 1933.2 They are so infinitesimal that billions could fit into a drop of water---or a drop of human blood. Viruses have the most exquisite ability to sense the right cell surfaces. They don't just cause diseases in people, they infect every form of life on earth. Some emerging viruses are very serious. Common ...

Of all the generations thus far to inhabit the Earth, we have the least excuse for not recognizing the quiet presence of The Scientific Mathematician who set everything into motion around us. We should be in awe, not presumptuous and skeptical. About 3,000 years ago King David of Israel wrote (Psalm 8:3-4) "When I consider Your heavens, the work of Your fingers, the moon and the stars, which You have ordained; w ...

El-nino

... Pacific waters that is brought about from time to time by naturally occurring oscillations in atmospheric pressure and ocean movements in th equatorial Pacific. The warmer ocean pumps more energy and moisture into the atmosphere and this in turn alters wind and rainfall patterns around the world. The atmospheric cirulation also changes when the sea-surface temperatures in the eastern tropical Pacific rise above normal. In normal, non-El Nino conditions, the trade winds blow towards the west across the tropical Pacific. These winds pile ...

Involvement Of K+ In Leaf Movements During Suntracking

... oriented perpendicular to the sun’s rays, thereby maximizing the interception of photosynthetically active radiation (PAR). In some plants, but not all, his response occurs particularly during the morning and late afternoon, when the light is coming at more of an angle and the water stress is not as severe (Donahue and Vogelmann). Under these conditions the lamina of the leaf is within less than 15° from the normal to the sun. Many plants that exhibit diaheliotropic movements also show paraheliotropic response as well. Paraheliotropism m ...

Greenhouse Effect

... Though not until recently has it become a priority. So important, that figures such as Vice President Al Gore have spoken out. Many are realizing that the is not something to be put aside, yet rather something to be worked on and studied. "The displays that nature is not immune to our presence" (Kralijic, 1992). Ways must be found to lessen the threat of this growing crisis. If this effect were to continue and grow, the earth’s population would be exposed to serious threats. Carbon dioxide is essential for plants who use it for photosynth ...

... about diagnosis. The annual incidence of schizophrenia is between 0.1 and 0.5 per 1000 depending on the diagnostic criteria used - representing a lifetime risk of 1 per cent (Strange, 1992). Onset of the disease is most commonly in late adolescence or early adulthood.
