Depression 4
....
Depression is one of the most common mental illnesses. At least 8 percent of adults in the United States experience serious depression at some point during their lives, and estimates range as high as 17 percent. The illness affects all people, regardless of sex, race, ethnicity, or socioeconomic standing. However, women are two to three times more likely than men to suffer from depression. Experts disagree on the reason for this difference. Some cite differences in hormones, and others point to t .....

Depression..a Deadly Disease
.... revealed by a combination of symptoms that interfere with the ability to work, sleep, eat, and enjoy everyday life. Disabling episodes of this disease can occur once, twice, or several times in a lifetime. Next, a less severe type of disease called dysthymia involves long-term symptoms that don't totally disable a person but does not allow them to totally function at "full-steam". Lastly, bipolar disorder involves cycles of depression. Mood changes can be dramatic and rapid or gradual. In the depressed c .....

Development Of Charles Darwin
.... perfectly.
The homogenization of Darwin's newly found interest in the physical sciences and analytical theory (helped by their father's gift of a chemical laboratory) with the slow and patient love of the natural world had repercussions felt around the globe. From playing with chemicals and earning the nickname of "Gas", to trips to the countryside, the young Darwin had been properly exposed to that which would become his lifelong burden: scientific thought and reason. Convinced that the Shrewsbury Scho .....

Second Generation Computers (1955-1965)
In the mid-1950's, the transistor was introduced, creating a more reliable computer. Computers were used primarily for scientific and engineering calculations and were programmed mainly in FORTRAN and assembly language.
As computers became more reliable they also became more business orientated, although they were still very large and expensive. Because of the expenditure, the productiveness o .....

Diabetes
.... fatigue, and other symptoms. Over time, high blood glucose can cause very serious medical problems.
Adding up the total toll of diabetes complications, the disease is one of the nation's leading causes of death. All diabetes complications can be largely prevented by practicing what is known as "tight control," keeping your blood glucose level as close to normal as possible. This takes time and energy, but many diabetics do it successfully and live full lives without much trouble.
Scientists don' .....

Diamonds
.... other hand, although it is the same element, is more loosely packed and has a six-sided, layered configuration, which makes it soft (Pough, 1991). The differences between graphite and diamonds are accounted for by the conditions in which they are created.
Diamonds form over long periods of time, between 100 km and 200 km below the surface. At this great depth, carbon gets a chance to cool very gradually, forming diamond crystals. When volcanic eruptions occur, magma carries the diamonds up to the sur .....

Dietary Fibre
.... is also discussed extensively in order to prove that clinical nutritionists are right to encourage intake of dietary fibre in increased amounts with caution to the fact that overindulgence may cause adverse effects.
Lastly the importance of high fibre foods in conjunction with a healthy lifestyle is presented as the 'formula' for a healthy body and avoidance of fibre depleted foods, a fact which is sadly abundant nowadays, is also mentioned.
Since ancient times, foods containing complex carbohydrate .....

Digestive System
....
Digestion begins in the mouth. Here the food is cut and chopped by the teeth. The tongue helps mix the food particles with a digestive juice called saliva, which is secreted in the mouth. Saliva moistens the food so it can be swallowed easily. It also changes some starches into simple sugars.
It is important to chew food thoroughly to mix it well with saliva. Thorough chewing cuts food into small pieces that are more easily attacked by digestive juices. Food should not be washed down with qua .....

Dinosaur History
.... Then
those mammals evolved into man. The Evolutionists believe that dinosaurs were extinct millions of years before there were even any people to walk the Earth. The Evolutionists had a hard time
trying to explain why dinosaurs became extinct. They have many different theories. One theory says that the impact of an asteroid or comet caused the destruction of the environment, leading to
the extinction of the dinosaurs. Evidence to support this theory includes the discovery of a buried impact crater ( .....

Dna
.... occupies the center of the nucleotide, with the phosphate group on one side and a base on the other. The phosphate group of each nucleotide is also linked to the deoxyribose of the adjacent nucleotide in the chain. These linked deoxyribose-phosphate subunits form the side rails of the ladder. The bases face inward toward each other, forming the steps of the ladder.
The nucleotides in one DNA strand have a specific association with the corresponding nucleotides in the other DNA strand. Because of the chem .....

Dna Chips And The Pharmaceutical Industry
....
Currently the pharmaceutical industry is a very high risk industry in which fewer than one in ten promising drug products ever makes it through the testing phase and onto the shelves at the local pharmacy. The effect is that the production of a new drug is almost like a guessing game that may or may not produce any profit. A Company may have a long list of chemicals that could make possible drugs to treat a specific affliction, but by the time they narrow the list down, and do the necessary researc .....

Do Science And Technology Provide A Solid Base For Technocra

The collapse of the Mianus River Bridge in Connecticut can be called a debacle of engineering designs, as well as the Hyatt Regency Walkways and all other disasters (Petroski 94-97) and without a doubt they were. But when one looks at the overlooked flaws in the design it is not hard to assert a level of responsibility .....

Dolphins 2
.... sixty million years ago a cow, the distant cousin of the dolphin, decided to take his life to the sea. This is shown by the findings of hooves on dolphin fossils.
The appearance of dolphins has intrigued man’s interest in the physical makeup of these mammals. Dolphins are carried by their mothers for twelve months before they are born. Once they are born, they immediately swim to the surface for their first breath of air. At the time of their birth, dolphins are three feet long and weigh approximate .....

Down Syndrome
.... 21 chromosome. Instead of the normal number of 46 chromosomes in each cell, the individual with Down syndrome has 47 chromosomes. This condition is called trisomy 21. The second type is called translocation since the extra 21 chromosome is attached or translocated on to another chromosome, usually on chromosome 14, 21 or 22. If translocation is found in a child with Down syndrome, it is important to examine the parents' chromosomes, since in at least one-third of the cases, a parent may be a carrier of .....

Dreams

This up bringing has also affected the way women dream. ³Women are more likely to dial into their interior life whether awake or asleep² (Segell 42). This means that women will read into their dreams more frequently then men. Researchers have found that problems that occur during the day either at work or home and are worked through in your sleep (Segell 42). While men would most likely look at these dreams as nothing but a .....
