.... have been known to denude a tree or ornamental plants in one night. It has been estimated they do $1 billion damage per year in North and South America today, these ants still cause millions of dollars in crop losses in many South American countries. Although primarily an agricultural pest, this insect on occasion may invade the home for cereals. In the United States, the Texas leaf-cutting ant, Atta texana , occurs in Texas and Louisiana. This ant is believed to cause a total yearly loss of $5 million in the United States (unison services. 1998). There are about 9,500 named species of ants. These ants are divided into 16 sub families and 300 genera, all which belong to the ....

.... There is no known specific cause for , but over the years there has been a growing focus on biological etiology. Combinations of psychotherapeutic and medical treatments, as well as comprehensive educational treatment provide the best care and placement of both adults and children afflicted with . Adult psychotic disturbances were noted in the early twentieth-century classifications of mental disorders (Nelson, Israel, 1997). The descriptions and classifications of these disturbances, however, were confusing and controversial. Kraeplin set the basis for modern classification. He used the terms dementia, a belief that progressive deterioration occurred, and praecox, ....

.... “He said the creation of transgenetic animals could be an important tool in ... ultimately stopping -- the aging process.” Becoming immortal is not the only plus to cloning. Furthermore, the research of cloning has helped scientists become aware of the way genes operate. With continuous research into the ways of cloning scientists could come to understand the ways cells and genes work. As the information grows we will be able to get rid of genetic diseases and defects. “As geneticists have come to understand the ways in which genes operate, they have also become aware of the myriad ways in which the environment affects their ‘expression.’” In the futur ....

.... chemical ingredient in beer, wine, and other alcoholic beverages is ethyl alcohol. Ethyl alcohol is a potentially addictive drug and a depressant of the central nervous system (Kestler 6). Alcohol acts as a sedative and as an anesthetic, reducing nerve transmissions and impulses to the central nervous system. This depresses mental, motor, and vital functions such as pulse rate, respiration, and blood pressure (Kestler 6). The body can absorb alcohol very quickly, approximately 20% goes directly into the blood stream from the stomach, the rest enters the body through the small intestine. Moments after alcohol enters the blood stream it reaches the Cerebral Cortex, the ....

.... materials, manufacturing processes, the transportation of the products, and how they are recycled once their usefulness has ended. Also, due to the extreme urban sprawl, an individual waste water system is used as an alternative to laying new collection pipes. This waste water system is designed to be totally self sufficient in meeting the needs of the occupants of the house. Large metallic cisterns, which store rainwater, are placed near the front of the house in such a way that it creates an entranceway into the house that lets visitors know the occupants concern for the environment. Along side the huge silver cisterns is the waste water cleaning system that was desig ....

.... is there are several potential reactions that can affect the oxidation of sulfur in the atmosphere, everyone with a different success. The second possibility is the reaction of sulfur dioxide with the atmosphere. Here are a few equations: 1. (2So2+O2 2So3 2) So3++120 H 2So4 The second reaction takes place very quickly. Therefore, the making of So3 in the damp atmosphere is assumed to be the lead to the formation of sulfuric acid. Phase two: the aqueous phase, sulfur dioxide occurs as three species. [S {iv}] [So2{aq}]+[+1S03-] +[So32-] This process occurs by a twofold process. 1) So2 (aq) H++H S o3- 2)H so3-(aq ) h++ So32- The establishment of the equilibrium ....

.... their energies can be used according to the kind of energy they emit. Since the mid 1900's radioactive wastes have been stored in different manners, but since several years new ways of disposing and storing these wastes have been developed so they may no longer be harmful. A very advantageous way of storing radioactive wastes is by a process called 'vitrification'. Vitrification is a semi-continuous process that enables the following operations to be carried out with the same equipment: evaporation of the waste solution mixed with the ------------------------------------------------------------ 1) borosilicate: any of several salts derived from both bor ....

.... 175,00 diffrent species. The main object of fungi is to decompose nutrients of plants and animals. History the history of fungi is not very clear because scientists have never realy wnt in great deepth , because fungi are not needed commericaly. the ancestors of fungi lived in shallow bodies of water about 600-800 million years ago. Some of the things the fungi had to encounter from living out of water was, there was more sunlight that was normally blocked be the water, and the had to do something about the rapid shifts in tempature and seasonal shifts. Fungi are different from other plants in many ways. The general characteristics of fungi are extracellalar digestio ....
