... seems to bother the person. Heroin is the most addictive narcotic. Of all narcotic addicts, 90-95% use heroin. In the United Stated alone, there are between 500,000- 750,000 heroin addicts. Heroin is often mixed with cheaper substances, so that the dealer can make a larger profit. Since addicts don't know about the purity of a substance, many die because of overdoses. In an overdose of heroin, the lungs stop functioning, and the person dies from lack of air. There can be other effects of heroin addiction, one is that people who have illnesses may have them go untreated because the heroin has masked the pain. Another is that peoples veins collapse, from havin ...
... Constructive interference occurs when two waves of the same frequency meet at a crest or trough therefore combining to form a wave that has an amplitude equal to the sum of the individual amplitudes of the original waves. Stimulated emission is the process that the laser works on, which was first proposed by Albert Einstein in 1917. When a sufficient number of atoms, either gas solid or liquid, absorb energy so that they are in an excited state of higher energy stimulated emission can occur. Light of a specific wavelength can produce more light with the same phase and direction these light waves will be coherent. Stimulated emission amplifies the cohere ...
... releases the lements it is made of. These elements are hydrogen and oxygen. Today's efficiency of this method is about 65 percent, however 80-85 percent are possible with more research. Another method of producing hydrogen is through chemical means. It is a scientific fact that every metal that is less noble than hydrogen will isplace hydrogen from water . Common materials used in this reaction is sodium or potassium . Sodium plus water will produce hydrogen , NaOH, and heat . Other reactions include the "producer" reaction that was discovered in 1800 . It involves combining heat, carbon, and water. It then yields hydrogen an carbon monoxide . Bacteria can also ...
... beings may have evolved from ape-like creatures. Even with this, there are still disputes in the paleoanthropological field of whether or not this is true. Still, many choose to believe their religious creation stories where a God created humans. Whether it is Johanson's idea on human evolution or Leakey's or even the Roman Catholic's creation story, all are an individual own interpretation and neither wrong nor right. A paleanthropologist by the name of Donald Johanson is one of the many who have a very different view on the origin of humans. In 1974, he discovered forty percent of an individual dating back to 3.5 million years ago. The individual, Australopith ...
... One difference between waking and dreaming consciousness is that the latter tends to be an internal hallucinatory-like experience disconnected from the external world. Many dreams collected in laboratories are rather common, but some people tend to experience some bizarre dreams. Early in the 20th century, Sigmund Freud believed that dream content was composed of the mental processes different from that used in the awake state. He believed this was what dominated the dreaming mind. He described this "process" as characterized by more primitive mechanisms, by rapid shifts in energy and emotion, and by a great deal of sexual and aggressive content derived from ch ...
... behind the upper eyelid at the outer corner of the eye. After passing over the eye, the liquid from the gland is drained into the nose through the tear duct at the inner corner of the eye. Heavy laughter or crying causes muscles in the upper eyelid to squeeze the lachrymal gland. This produces tears that flow too fast to be drained away. The eyelashes catch many flying particles that otherwise would enter the eye. As further protection, the eyelids automatically close when an object suddenly moves close to the eye. The eye is made of 3 coats, or tunics. The outermost coat consists of the cornea and the sclera. The middle coat contains the main blood supp ...
... important to know that we are now live in a digital age. As the saying goes, every business now is an information business, our information technology industry is driving ahead with advances that promise to bring the new medium into the living rooms and onto the desks of millions more. So, in this part, I will discuss the advantage that information technology brings to our work and analyses it in-depth. Last but not least, as technology continues to develop, I also give the opportunities and threats for our businesses in the coming Internet age and how we can achieve information advantage. Most managers acknowledge IT will be one of the main factors that affect the ...
... and how does it work?” What are they to do when a teacher assigns the students to send in all assignments by e-mail? Eventually, they will have to learn the basics of e-mail which, in turn, reveals even more problems with being computer illiterate. For an essay, the teacher requires that they go to the library to do research. The computer illiterate happily walks into the library to do their research. Imagine their surprise when they find out that the main tool of research is one of those darn computers. The poor illiterates stare blankly at a computer screen while the monotone library aide goes through a boring speech about how to use the computer. ...
... the molecules of the continuous phase are trapped in the holes of a "brush-heap" like structure of the gelatin. Administered orally. Microemulsion: Microemulsions are thermodynamically stable, optically transparent, isotropic mixtures of a biphasic oil-water system stabilized with surfactants. The diameter of droplets in a microemulsion may be in the range of 100 A to 1000 A. Microemulsion may be formed spontaneously by agitating the oil and water phases with carefully selected surfactants. The type of emulsion produced depends upon the properties of the oil and surfactants utilized. Ointment: Semisolid preparations intended for topical application. Most oi ...
... tests, which, because the current tests are time consuming and technically difficult to do, are restricted to women over 35 and those who have a family history of chromosomal abnormalities. Prenatal tests using Willard's probes would be much simpler and faster to perform and could be available to all pregnant women who wish to take advantage of the technology. Current prenatal testing involves growing fetal cells in vitro and examining them, over one or two months, to see if there are two copies of a particular chromosome, which is normal, or one or three, which is abnormal. A test using Willard's probes would require only a few cells and a few days to d ...
