These changes may result in a loss of soil organic matter, a decrease in soil fertility (Garcia-Oliva et al. 1994, Tissen et al. 1994), severe soil erosion (Otzen 1993), and changes in soil structure and chemistry (Fernandes and Sanford 1995, Sollins et al. 1995, Montgagnini and Sancho 1994.) The response of tropical rain forest soils to deforestation depends upon the specific properties of the soils as well as the type of

The primary sex characteristics enlarge and mature: in males--the testes, prostate gland, penis and seminal vesicles, in females--the ovaries, uterus and vagina (Papalia, et al., 1998). 4.

large, breathing becomes difficult and death may result. Silicosis victims are also at high risk of developing active tuberculosis [Myers et al. 1973; Sherson and Lander 1990; Bailey et al. 1974]. A worker's lungs may react more severely to silica sand that has been freshly fractured (sawed, hammered, or treated in a way that produces airborne dust) [Vallyathan et al. 1988]. This factor may contribute to the development of acute and accelerated forms of silicosis. Types of Silicosis A worker may develop
algae of the genus symbiodinium. These algae are commonly called zooxanthellae. This symbiosis between heterotrophic hosts and photosynthetic symbionts allows coral to thrive in nutrient poor seas and deposit calcium carbonate to build reefs (Toller et al. 2001, 348). Coral bleaching occurs when there is a loss of zooxanthellae from their coral host. This is accompanied by loss of a coral's normal color that may or may not be detectable to the human eye. Bleaching can lead to coral death when prolonged

numerous accounts of its medicinal qualities in multiple historical artifacts. Its use dates back to 2737 B.C. when the Chinese emperor, Shen Nung, used it for medicinal purposes including malaria, gout, poor memory, rheumatism, and analgesia (Carter et. al., 2003). Eastern Indian documents, in the Atharvaveda, dating back to 2000 B.C. also refer to its medicinal use. The Jamestown settlers cultivated hemp produced by the marijuana plant. They used these fibers to make clothing, rope, and canvas

conception (qtd. in Lefkowitz et al. 228). Plato asserts that because "all concoction works by means of heat" and "some of the body's parts are 'principles'" (qtd. in Lefkowitz et al. 229), a lack of heat will affect concoction which will, in turn, affect a principle body part. This is crucial to the development of the body as "once a principle has been 'moved' (i.e. changed), many of the parts which cohere with it must of necessity change as well" (qtd. in Lefkowitz et al. 229).

inclusion of after-care activities for inner-city youth in any successful educational spending program. Odden et al. note that their analysis of spending patterns across the 50 states is supported by the conclusions reached by the Finance Center of the Consortium for Policy Research in Education (CPRE), although the results of their research did diverge in some significant ways. Odden et al. examined spending and staffing patterns at the district and school levels. They also scrutinized staffing patterns
Aluminum Aluminum is the second most abundant element in the Earth’s crust. It has a concentration of about 8.2 percent (Craig et al 264). Aluminum “is malleable, ductile, and easily machined and cast; and has excellent corrosion resistance and durability” (http://minerals.usgs.gov/). It is evident in everyday life. Aluminum is a very useful abundant metal. A large fraction of the mineral products we seek are metals, such as aluminum (Halleck, 1/20). The major uses of aluminum are transportation
specific antibody response that is responsible for HAR. An in vitro kinetic experiment combined rat endothelial cells with primate serum and then measured bound human and monkey antibodies, number of lysed cells, and C complement activity (Azimzadeh et al., 1996). The results showed that IgM antibodies were produced rapidly in the earliest stage, after which a large number of IgG antibodies were produced. Components of the C cascade were present on the endothelial cells. Th... ... middle of paper
biased in their writing. All of these reasons make it a poor argument over a very important subject. In the article, “Medicating Young Minds” author Jeffrey Kluger goes into detail about the problems of medicating children today. It is Klugers et al belief that it should not be happening; medicating the youth. His argument is logical to himself but, it may not be to everyone, especially people who need medication to survive. Kluger uses a sarcastic tone and is somewhat biased in his article. He
most controversial herbal remedies is St. John’s Wort. As a cheap over-the-counter antidepressant, and with over 17% of the population experiencing depression sometime in their lifetime, its allure to the lay person is not surprising (Kessler, R. C. et al., 1994). Is St. John’s Wort an effective treatment for depression as many claim it is? Is it really safe? St. John’s Wort, often called hypercium for its botanical name, Hypercium perforatum, is derived from a yellow flowering plant. Hypercium is
all, as Voltaire said, “No opinion is worth burning your neighbor for” (Bulliet et al. 468). One can never put the world wars into the black-and-white categories of ‘good’ and ‘bad’ into which they have often been placed. But it will be interesting to explore the positive and negative effects of the wars, which changed the world forever as shown in The Earth and Its Peoples: A global History by Richard W. Bulliet et al., historical films like History Channel’s Manhattan Project - The Century and Heritage:
exception. Most literature supports the view that victims of SIDS suffer a failure of the automatic control of respiration, producing periodic apnea and eventually death. Neural control of respiration involves three anatomical structures (Armstrong et al., 1982~. The first is the motor system, which contains the neurons which initiate and maintain respiration. These include the dorsal motor nucleus of the vague, the nucleus tractus solitarius, the nucleus ambiguous, the nucleus retro-ambiguous, the
percent of a jellyfish’s body is "solid organic material" (Halstead, Poisonous 96-97). Jellyfish have reproductive cycles that involve a sessile polyp and a free-living medusa state. The polyp is asexual, while the medusa is sexual (Williamson et al. 121). P. physalis actually consist of colonies of many small organisms. A single Man-of-War contains both polyp and medusal stage organisms, with several different types of polyps and medusae in a colony (Halstead, Poisonous 94-95) Jellyfish populations

enroll at the same time and go through a program by taking the same courses at the same time, a process that is sometimes referred to as lock step (e.g., Chairs et al. 2002; Reynolds and Hebert 1998). A cohort is much more than a structure, however (Norris and Barnett 1994). It is "a tight-knit, reliable, common-purpose group" (Drago-Severson et al. 2001, p. 15) that has foundations in group dynamics, adult development, and adult learning theory (ibid.; Nesbit 2001; Norris and Barnett 1994).

200 yards. The other weapon of choice, the shotgun, did not boast a straight, clean shot, but had the capacity to tear anything to shreds in a single blast. A short barrel provided the advantage of a wider blast range and easier handling (Trachtman et al 50). In many battles, the shotguns were often preferred for their simplifying features. In the frequently lawless country that the United States had become, a quicker solution for combat was deemed necessary. It did not take long for such handguns
