... forty-eight millimeters long, thirty-four millimeters wide, and seven millimeters thick. From the ventral view, the left side was serrated. This seemed like the most appropriate side to use as a saw. A small round twig, a centimeter thick, from a local deciduous tree was used as the wood subject. The exact species of the tree is unknown; however, it was a very hard wood and a light brown/tan color. Initially, medium pressure was used on the flake and it was moved in bi-directional strokes across the stick. After about thirty strokes, the use edge angle prohibited the flake from cutting further in to the stick. The cut was roughly three ...

... woodpecker habitat on limited federal holdings in the American southeast. Key words: Picoides borealis, Global Positioning System, Geographic Information System, cavity trees, cavity restrictors The red-cockaded woodpecker (Picoides borealis) is an endangered species that inhabits pine forests in an historical range from Texas to the Atlantic coast (Jackson, 1986; Reed et al., 1988). Picoides borealis nest in clans or family groups that usually consist of one breeding pair and 2 non-breeding male helpers (Jackson, 1986 ). This group establishes and defends a territory that includes foraging habitat and nesting "cavity trees" (Copeyon et al., 199 ...

... not the vast resources that we believe them to be, but just vulnerable natural resources. Before Columbus' day, the ocean were thought to be boundless. Although Columbus proved this theory incorrect, the thought still remains in today's societies. “For we of the 20th century still treat the ocean as the endless, bottomless pit it was considered to be in medieval times.”(Heyerdahl) The majority of the world's population still lives under the misconception that the ocean is a hungry abyss, eager to devour all their waste. These beliefs, however, are all untrue. The average depth of the oceans is only a little more than a mile, when in fact, some lakes exceed t ...

... and always referred to as such. Though his first knife may well have been government issued, he learned the tricks of the trade in due course and sometimes became quite an expert. “Do your best” was the general idea, and most surgeons did, or at least tried. Nearly all the older doctors had received their education on an apprenticeship basis but the younger men, those who made up the bulk of the army surgeons, usually held a medical school diploma along with an office internship. Little attention was paid to clinical instruction, and in most cases the laboratory was all but forgotten. Further, stethoscopes, thermometers, syringes, and the like were widely used ...

... over a trillion dollars' worth, of manufactured items are produced with the help of catalysts every year. It is therefore logical that scientists are constantly searching for new improved catalysts which will improve efficiency or produce a greater yield. An acidic catalyst works due its acid nature. Catalysts are strong acids and readily give up hydrogen ions, or protons: H+. Protons can be released from hydrated ions, for example H3O+, but more commonly they are released from ionisable hydroxyl groups (R-OH) where the O-H bond is broken to produce R-O- and H+. When the reactant receives protons from an acid it undergoes a conformational change, (change in shape a ...

... easily distracted and have limited attention spans. They can sit for a while and pay attention if the topic is interesting to them. People with Attention Deficit Disorder usually do this while watching TV, playing Nintendo, and at sporting events. Many ADD children will tell you how annoying it is when someone around them is talking. People with ADD are impulsive meaning to act without thinking. In one case a five-year old with ADD almost drowned when he went to a pool with his father. He saw people jumping into the pool and thought it would be fun. He jumped right in without remembering that he can't swim. He was pulled from the bottom of the pool several m ...

... on Acid rain with all the other important environmental topics? I chose it because we are subjected to precipitation all the time. I was interested to see just how dangerous acid rain is. If it really is dangerous, I was also interested to see what thing's people can do to help stop its effects. If we cannot stop the effects, I would atleast like to know something’s I can do to lessen the effects on our environment. What is acid rain? Acid rain is the name commonly given to the deposition of a cocktail of acidifying compounds to soils, surface waters and buildings. These compounds arise mainly from the combustion of fossil fuels. In some parts of the Unite ...

... show that as many as 100 species become extinct every day with a large portion being attributed to deforestation (Delfgaauw, 1996). "Edge effects" are the destruction or degradation of natural habitat that occur on the fringes of fragmented forests. The effects for the animals include greater exposure to the elements (wind, rain etc…), other non-forest animals and humans (Dunbar, 1993). This unnatural extinction of species endangers the world's food supply, threatens many human resources and has profound implications for biological diversity. Another negative environmental impact of deforestation is that it causes climate changes all over the world ...

... growing, field of clinical psychology. ("An analysis") The jobs of clinicians in this field vary greatly, but all areas deal with some interaction of psychology and the law. For this reason, the field is often referred to as Criminal Psychology. Forensic psychologists are most known for working in the courts but they can also work in work in a penal institution, state mental hospitals, law enforcement agencies, or a private practice (The Page"). Forensic psychologists also provide treatment services. These include counseling for adults and children involved in divorce proceedings and anger management counseling ("Psychology Information Online" 1998). Forensic ps ...

... portrayed in much of the cultural art and through the tales in their oral tradition. In its most simplified form, a tsunami can be defined as a series of waves most commonly created by violent movement of the sea floor. A tsunami is a towering ocean wave generated by tectonic displacements such as undersea earthquakes, landslides, cosmic collisions, or volcanic eruptions. There is a common misconception that a tsunami is a tidal wave. Although the impact of a tsunami on a coastline may change depending upon the tidal level at the time when one occurs, tsunami waves are unrelated to tides. Instead, tides are the product of imbalanced gravitational forces co ...
