In order to confirm this he exposed the patient to artificial sunlight. He found that over a period of time the patient had recovered from the depression. Today light therapy is the most commonly ... in treating SAD. The two hormones that are affected by the sunlight, and are thought to be the cause of SAD, are melatonin and serotonin. Both of these chemicals “are influenced by photoperiodism, the earth’s daily dark-light cycle” (Wurtman 1989). Melatonin is the chemical that effects mood and energy levels. In the human body melatonin is at its highest at night and is lowest in the day. There ...

- 24544: Geothermal Energy 2
- ... is converted to steam by using changes in pressure. The steam and liquid are separated, with the steam turning turbines (generating electricity) and the water is injected back into the reservoir to maintain the chamber's pressure. Sometimes the hot water is used directly for home, and sometimes greenhouse, heating. It is also used to speed up the growth of aquatic animals (aquaculture). II. Dependency on Geothermal Energy Although we (the ... advantage of all of the geothermal sources in the United States, the source is here today; it is not merely a hope for the future. The production of geothermal energy ranks third in the country's renewable resources, behind hydroelectric power and biomass conversion. Worldwide, there are more than 7,000 megawatts of electricity being generated. This is equivalent to production of about seven nuclear power plants. III. Benefits: Energy Efficiency As a result of today's use of geothermal energy, the consumption of nonrenewable resources is slowed down, resulting in subsequent slowing down of acid precipitation and the release of greenhouse gases caused by fossil fuel use. Sources of this ...
- 24545: Leprosy
- Leprosy Leprosy or Hansen’s disease, is a chronic, infectious disease that mainly affects the skin, mucous membranes, and nerves. A rod shaped bacillus named Mycobacterium leprea, causes the virus. Mycobacterium leprea is very similar to the bacillus that causes tuberculosis. The reason Leprosy is also known as Hansen’s disease, is because it was first identified in 1874 by a Norwegian physician named Gerhard Henrik Armeur Hansen. Leprosy appears in both the Old and New Testaments. In the bible Leprosy was not the disease ... God was what these conditions were considered to be. The victim was said to be in a state of defilement. This Hebrew term was translated as lepros, which the word leprosy came from. The disease’s probable origin was the Indus Valley that is located in India. Leprosy spread from there to the Mediterranean region and North Africa, then all of Europe was affected. This disease is much less common ...

- ... most important natural resource is its rivers. The rivers play such a vital role in producing electricity. The rivers have a host of different hydro plants on them.

The rate of reinvestment has been very high in Norway for a number of years. This is illustrated by ... government guidelines, and this helps to control the rapidly expanding economy.

- 24547: Iron Absorption from the Whole Diet: Comparison of the Effect of Two Different Distributions of Daily Calcium Intake
- ... and more in her breakfast and evening meals, then this would reduce the inhibitory effects calcium has on heme iron and nonheme iron absorption. Background Information - This experiment is one of many that addresses calcium’s inhibitory affects on iron absorption. In 1994, the Consensus Development Panel in Optimal Calcium Intake suggested an increase of the current Recommended Dietary Allowances of calcium(Whiting, p.77). This goal of this increase was to aid in the prevention of osteoporosis and other bone diseases. Unfortunately, this attempt at prevention could have an adverse affect on the human body’s ability to absorb iron. Recent studies have shown that eating a normal daily allowance of calcium cuts iron absorption by as much as 50-60%(Hallberg et al. p.118). Other studies examine the affect ... Another group of scientists theorizes that iron is able to be transported into the epithelial cells without problem, however the iron then has trouble getting into the blood stream. The presence of calcium inhibits iron’s ability to leave the epithelial layer. Another very interesting theory is not on the microscopic level but in the evolutionary plane. Eaton et al. state that one possibility for this phenomenon could lie in ...

- 24550: Global Warming 2 --
- ... aside from pollution is one of scientists biggest concerns. Global Warming is caused by the Greenhouse effect. There are 4 steps in the Greenhouse effect. 1-Sunlight radiates from the sun, through space, to Earth's atmosphere. 2- The sunlight enters the atmosphere and hits Earth. Some of it turns into heat energy in the form of infrared light. The heat gets absorbed by surrounding air and land, which in turn makes it warm. 3- Infrared rays, that are remitted into the atmosphere are trapped by greenhouse gases. 4- The gas then absorbs the light and is remitted back to the Earth's surface and warms it even more. Some of the naturally occurring greenhouse gases are Methane and carbon dioxide. This is the way the Earth keeps itself warm enough for humans to live on it. The ... have increased concentrations of aerosols in atmosphere, which is a traditional form of air pollution), which tends to cool the atmosphere. With all these gases in the air, it is starting to change the Earth's climate. The temperature of the Earth's surface is as warm, if not warmer than it has been in any other century since at least 1400 AD. The temperature over the past century has ...
