- 2631: How Technology Effects Modern America
- ... 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 ... of our countrys political process, in a technologically advanced world. Voting & Poisoned Political Process in The U.S. The advance of mass communication is natural in a technologically advanced society. In our countrys short history, we have seen the development of the printing press, the radio, the television, and now the Internet; all of these, able to reach millions of people. Equally natural, is the poisoning and corruption of ...
- 2632: Penguins: The Eyes Have It!
- ... the eye. If you've every wondered what it would be like to be able to see as clearly under water as you can on land, just ask the nearest penguin.Most aquatic animals are short-sighted on land. Most terrestrial animals (and that includes us) are far-sighted under water. But researchers have discovered that penguins can apparently see equally well in both environments, because of the unique structure of ... true. During a recent stay on the Falkland Islands, a Canadian researcher discovered that penguins are able to recognize individuals and navigate the rocky terrain on which they live quite well. Long of body and short of leg, they probably poke their heads forward as an aid to balance. And as for looking at the ground, they're merely-like us-keeping an eye on where they're going. The human ...
- 2633: Microwaves
- ... radar, using radio waves. But the trouble with radio waves is that their long wavelength requires a large, cumbersome antenna to focus them into a narrow radar beam. The British showed that microwaves, with their short wavelength, could be focussed ina narrow beam with an antenna many times smaller. This enabled them to make more effective use of radar since an antenna could be carried on aircraft, ships and mobile ground ... absorbed by the outer layer of the chicken. Food cooks in an ordinary oven as the heat from the air and the outer layer of the food slowly seeps down to the inner layers. In short, oven microwaves cook the outside of the chicken at the same time as they cook the inside. Infrared energy cook from the outside in - a slower process. This explains why preheating is necessary in a ...
- 2634: Current Status of Malaria Vaccinology
- ... human hepatoma cells. Despite such encouraging animal and in vitro data, evidence linking protective immunity in humans to levels of CS antibody elicited by natural infection have been inconclusive possibly this is because of the short serum half-life of the antibodies. This study involved the volunteering of 199 Thai soldiers. X percentage of these were vaccinated using R32 Tox -A prepared in the way previously mentioned and as mentioned before ... he identified using antibodies from people immune to malaria, and injected these antigens into monkeys and eventually found four that provided some immunity to malaria. He then sequenced these four antigens and reconstructed dozens of short fragments of them. Again using monkeys (more than a thousand) he tested these peptides individually and in combination until he hit on what he considered to be the jackpot vaccine. But the WHO a 31 ...
- 2635: The Grasslands
- ... search for food at night during hot summers, search for food daytime during mild winters. Learn to stay hidden in shrubs, in fear of air predators. 6. Plovers- These birds have stout bodies with a short neck and tail. Bills in most species are short and stout and are swollen at the tip. Many species also have bands or rings around the neck. Plovers are swift in flight and forage actively on the ground or in shallow water for insects ...
- 2636: New Developments or Research in Genetic Cloning: Summary
- ... clipped from the surrounding DNA and copied millions of times. Each restriction enzyme recognizes a unique nucleotide sequence wherever it occurs along the DNA spiral. This nucleotide sequence, known as the recognition site is a short, symmetric sequence of bases repeated on both strands of the double helix. After the segment is removed, the ragged, or "sticky" ends that remain after cleavage by the restriction enzyme allow a DNA restriction fragment ... bacterial vectors and rapidly amplifies the chosen segment of DNA in the test tube without the need for living cells. In this process, the DNA sequence to be amplified is selected by primers, which are short pieces of nucleic acid that correspond to sequences flanking the DNA to be amplified. After an excess of primers is added to the DNA, together with a heat-stable DNA polymerase, the strands of both ...
- 2637: Life of Octopus Dofleini
- ... respect that they focus by moving in, and out. Whereas the human eye focuses by changing the shape of the lens its self. The octopus posses the most advanced brain of all invertebrates, with both short, and long term memories. This allows the octopus to learn in much the same way as humans, through trial and error. When an octopus learns a lesson it remembers and puts its knowledge to use ... have particular suckers that are larger than the rest, This is to aid in reproduction. Although octopuses often lose arms to predators, it is of no consequence as the arm will grow back in a short time. The Pacific Giant Octopus is of the phylum mollusca, class cephalopod, order octopoda, family octopodidae, and their closest relatives are the chambered nautilus, squid, and cuttle fish. The squid is in many ways similar ...
- 2638: Bats
- ... its body, large naked ears, its rear legs have claws, it has a tail membrane, and it has the most distinguishing feature of a bat, wings (Lauber 9). The upper arm of the bat is short while the forearm is very long. The wrist is very small and from it comes the thumb and the four longer fingers. The thumb is short and used for climbing or walking. The fingers are long and thin. Interlocking the fingers is the wing. This set up of having the fingers in the wing gives the bat amazing flight maneuverability (Honders ...

This is just short overview of the origination of Buddhism and the Buddha. Along with a short overview over the beliefs and customs of the religion.
