.... is what employers want! "There is clear evidence that the supply of workers in the [unskilled labor] categories already exceeds the demand for their services," says L. Mishel, Research Director of Welfare Reform Network. In view of these facts, I wonder if these trends are good or bad for society. "The danger of the information age is that while in the short run it may be cheaper to replace workers with technology, in the long run it is potentially self-destructive because there will not be enough purchasing power to grow the economy," M. B. Zuckerman. My f .....

.... flexible manipulation required for a successful ‘strike’, or actual crystallization, of solid sugar . For this purpose, the concentrated liquor is transferred from the evaporators to the ‘pan.’ The pan is essentially a simple vacuum evaporator in which the removal of water continues until the concentration is appropriate for crystallization. As this proceeds, juice continues to be drawn into the pan in order to maintain a supply of crystallizable sugar. The concentration of impurities increases in the syrup as sugar is withdrawn by crystallization, and the enti .....

.... in sea level, along with other severe environmental agitation. An example of a runaway greenhouse effect is Earth's near-twin planetary neighbor Venus. Because of Venus's thick CO2 atmosphere, the planet's cloud-covered surface is hot enough to melt lead. Water vapor is an important "greenhouse" gas. It is a major reason why humid regions experience less cooling at night than do dry regions. However, variations in the atmosphere's CO2 content are what have played a major role in past climatic changes. In recent decades there has been a global increase i .....

.... the mis-management of our oceans. The Sahel is a strip of land that extends for more than 6000 kilometres across the southern edge of the Sahara desert. It stretches from Senegal and Mauritania in the west to Ethiopia and Somalia in the east. These nations are among the world's poorest. The area is one of social and biophysical crisis because of the way the population are forced to live; they are destroying the productivity of the land. The alarming rate of population growth and ever increasing pressure on the land have initiated an expansion of desert-like c .....

.... from the body in the process called menstruation. What is the birth control pill? The combined oral contraceptive pill (the pill) is a reversable, hormonal method of birth control. The pill consists of a mixture of two synthetic hormones similar to oestrogen and progesterone, the woman’s natural hormones which regulate the menstrual cycle. The pill is on of the most popular methods of birth control. How does it work? The pill basically prevents ovulation, therefore, the ovaries can’t release a mature egg. Without an egg for the sperm to fertilize , a wo .....

.... that article is true. One of the things he mentions is that the former Soviet Union had the largest big-warfare program in the world, with 32,000 scientists working on it. Much of it had to do with genetic engineering. In one of the projects they took smallpox, which has otherwise disappeared from the world, and found a way to genetically introduce into it, without reducing its efficacy as smallpox, either Ebola virus or equine encephalitis viruses. Nobody seems to know what happened to those experimental viruses. A third example: we now have plants ge .....

.... its way north. Before the vernal equinox the sun hits the northern surface at an angle instead of hitting it directly. By hitting the earth's surface at an angle there is not as much radiation warming the surface. As the earth rotates and the sun moves further north the temperature increases and the weather turns warmer. During the three months of spring the sun continues to move north and warming the earth more efficiently. At around June 21st the sun is directly facing the tropic of cancer. At this time the movement north comes to a halt and the earth's s .....

.... smallest shrews, mice, and bats are often less than 5 cm (less than 2 in) in length. In many mammals the color of the skin or fur blends with the animal’s natural surroundings. In others there is great contrast with the natural surroundings to favorvisual signals that provide information about theidentity of a species, and about the gender, age, orsocial status of an individual. The skin also functions as a sensory and excretory organ and contains specialized glands. Mammary glands, which are present in fully developed form in all adult female mammals .....
