.... the Great Lakes, such substances as limestone or other known antacids can neutralize acids entering the body of water thereby protecting it. However, large areas of Ontario that are near the Pre-Cambrian Shield, with quartzite or granite based geology and little top soil, there is not enough buffering capacity to neutralize even small amounts of acid falling on the soil and the lakes. Therefore over time, the basic environment shifts from an alkaline to an acidic one. This is why many lakes in Muskoka, Haliburton, Algonquin, Parry Sound and Manitoulin districts could lose their fisheries if sulphur emissions are not reduced .....

Instead of the normal number of 46 chromosomes in each cell, the individual with 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 , it is important to examine the parents' chromosomes, since in at least one-third of the cases, a parent may be a carrier .....

.... under control. We must step carefully into this vast new field of science with the understanding that putting a patent on the melanoma gene or the baldness gene for that matter is simply playing God in a potentially dangerous way.” (Appleyard, Bryan, Jan 98, Smithsonian) These are only a few examples of scientific developments that in my mind raise the question: in science? Mr. Appleyard could not have been more on point in his allusion to Aldous Huxley’s novel “Brave New World” which along with Mary Shelley’s novel “Frankenstein” raises the same question regarding our advancements in science. Where do we draw t .....

"The anemia that may result can take many forms, including that caused by a low iron level (iron deficiency anemia), a vitamin deficiency (megaloblastic anemia), a thyroid deficiency, the premature destruction of red blood cells (hemolytic anemia), replacement of normal bone marrow cells by cancer cells or leukemia (myelophthisic anemia), injury to bone marrow (aplastic anemia), and inborn structural defect in red blood cells (e.g. sickle-cell anemi .....

.... Globe valves are the second most common valve used I industry. A globe valve places a movable metal disc in the path of a process flow. This type of valve is most commonly used in the throttling service. Ball valves take their name from the ball-shaped, movable element in the center of the valve. The movable ball rotates to let flow pass through, and closes to stop it. Ball valves are not made for throttling service. Check valve is a type of automatic valve designed to control flow direction and prevent possible contamination or damage to equipment. The check valve prevents backflow as long as the device is o .....

.... Key words: teaching sociology, information technology, on-line teaching Introduction Information technology is quickly becoming the hub of efforts within the higher education community. Indeed, colleges and universities have demonstrated a fierce rush to amass technological tools, and are only now addressing the possibilities for adapting them to academic use. Ideally, new networked information technologies, such as the World Wide Web and E-mail will become fruitful pedagogical tools for faculty of all disciplines. As academic libraries are "virtualized" and classrooms are equipped for Internet, teleconferencing, and d .....

.... insurance. The fact that MSFS has entered the Financial Services Sector comparatively recently and with a established IS knowledge base from the parent company has meant that existing information systems have been well developed in terms of technology and are compliant with the latest industry regulations. Therefore there is little or no need for redevelopment of existing systems in the short to medium term, and the ISD focus is almost exclusively on new market areas requiring Information Systems that can be started from scratch. The main exceptions to this are the possibility of introducing data warehousing to tap th .....
