Thomas Hardy's The Convergence Of The Twain The poem The Convergence of the Twain, by Thomas Hardy, is about the sinking of the Titanic. The title alone describes the ship and the iceberg meeting as one. By choosing this title, the author automatically conveys a seriousness of the poem. The author uses various literary techniques to convey his mockery and careless attitude towards the sinking of the ship. In the first five stanzas, the author discusses the already submerged ship. ?Stilly
cartilage that appear to inhibit cancer (93). Curious, I continued to read the rest of the article. The chemicals block a mechanism discovered in the mid-1980s at Harvard University: Tumor cells secrete a protein called angiogenin that entices blood vessels to grow close to cancers and nourish them. The shark extracts counteract angiogenin and the tumor starves (93). I sat there pondering the concept and decided that I would further investigate this intoxicating find. Physiology of the Shark The
not determine the direction. During World War I, with the invention of submarines came the need to locate them. Research of underwater sound location was a primary focus for the British. Both the U.S. and Britain were researching what would be Sonar, and it was kept secret throughout the war. By 1922, units were being produced and by 1923, they were being equipped to naval vessels. Throughout the war, Britain referred to this underwater locator as ASDIC, which was the Anti-Submarine Detection
The brain is permeated by a vast network of tiny blood vessels called capillaries- so tiny and thin that blood cells have to pass through in single file. In the brain alone there are enough capillaries that if you laid them all out end to end they would stretch from Tucson to Tijuana. These capillaries are surrounded by a single layer of cells. That layer of cells forms a barrier between the capillaries and the cells and fluid of the brain. These barrier-forming cells are called "endothelial
Treatment for Raynaud’s - 2 - Introduction Raynaud syndrome is an auto-immune disorder in which blood vessels in the digits constrict. It usually strikes females between the ages of eighteen and thirty. “Between three to five percent of people are affected.” (Harvard, 2003) There is no known cause or cure. (Segala et al, 2003) Clinical features primarily deal with (but are not limited to) the digits of the fingers. Other digits that may be affected include toes, nose, and ear lobes. Exposure to cold
that has an enormous influence over many brain functions. It is synthesized, from the amino acid L-tryptophan, in brain neurons and stored in vesicles. Serotonin is found in three main areas of the body: the intestinal wall; large constricted blood vessels; and the central nervous system. The most widely studied effects have been those on the central nervous system. The functions of serotonin are numerous and appear to involve control of appetite, sleep, memory and learning, temperature regulation,
Development of the Torpedo during World War I The year is 1942, and German U-boats are wreaking havoc on allied shipping to Britain; the vital lifeline which allows the island nation to survive. Unchallenged, they sink hundreds of the merchant vessels which carry the desperately needed food, arms, and other equipment that is necessary for Britain's survival. They are silent and deadly; undetected until it is too late. With a loud deafening blast, a torpedo impacts the center of a ship, breaking
the wear and tear of aging, while research indicates that the nervous system may often be equally involved. About one out of seven Americans exhibit some form of arthritis. INFLAMMATORY CONNECTIVE TISSUE DISEASES This varied group of diseases produces inflammation in the connective tissues, particularly in the joints. The signs of inflammation--warmth, redness, swelling, and pain--may be apparent. Microscopic examination of the lesions reveals prominent blood vessels, abnormal accumulations of white
off to the side. We are being confronted with this problem and we need to find ways to resolve the present situations. The forms of confrontation are through foriegn invaders and lack of apex predators (to name a few). We must realize that through research as well as changes in lifestyle we can save our planet. These changes must occur individually for them to be a true success. Introduction back to outline Ecosystem instability is obvious through the depletion of our natural food webs. There are
But scientists have not observed tolerance to cocaine's stimulant effect: users may keep taking the original amount over extended periods and still experience the same euphoria. Physical effects of cocaine use include constricted peripheral blood vessels, dilated pupils, and increased temperature, heart rate, and blood pressure. The duration of cocaine's immediate euphoric effects, which include hyperstimulation, reduced fatigue, and mental clarity, depends on the route of administration. The faster
of its effects by hindering the flow of prostaglandins. Prostaglandins are hormone-like substances that influence the elasticity of blood vessels. John Vane, Ph. D., noted that many forms of tissue injury were followed by the release of prostaglandins. It was proved that prostaglndins caused redness and fever, common signs of inflammation. Vane's research showed that by blocking the flow of prostaglandins, aspirin prevented blood from aggregating and forming blood clots. Aspirin can be used
and temperature) and internal factors (for example, emotions, metabolism, and the presence of excess oxygen). Common antioxidants are Vitamins A, C, E, and beta carotene. These special chemicals assist in skin repair and the strengthening of blood vessels. Why do we need them? Antioxidants are necessary because they combat free radicals. Free radicals are byproducts that are formed when oxygen is used by the body (http://ificinfo.health.org/antidox.htm) . Free radicals start a chain reaction
skull. Another way the brain keeps it self safe is by keeping itself in liquid. Nearly one fifth of the blood pumped by the heart is sent to the brain. The brain then sends the blood through an intricate network of blood vessels to where the blood is needed. Specialized blood vessels called choroid plexuses produce a protective cerebrospinal fluid. This fluid is what the brain literally floats in. A third protective measure taken by the brain is called the blood brain barrier. This barrier consists
What is happening in research? ¨ Many doctors and scientists are investigating the cause and cure of lupus. At medical centres worldwide (including Canada), research has led to improved tests and techniques for diagnosis and better methods for predicting flares. These allow doctors to start treatment sooner, which improves chances for success. As part of research, many centres collect and store patient information and statistics. The results of this data can help doctors and patients make better
Ancient Egyptian Pottery I chose to do my research paper on Egyptian pottery because in my art appreciation class I was most fascinated with the ancient Egyptian era. I found this website that explained all about how pottery they made helped them function in everyday use. It also told me a lot about how the made everything. The need to store things led to the development of containers, first among them bags of fiber or leather, woven baskets and pottery. But clay lends itself to many other purposes:
not live past five years of its onset(1). Currently, not much is known about Binswanger's Disease; in many ways it resembles various other neurological disorders making it difficult to diagnose. The trademark of this disease is damage to the blood vessels in the deep white matter of the brain(1),(4),(5). The pons, basal ganglia, and thalamus are typical sites for these lesions(5),(7). A Magnetic Resonance Imaging scan is one of the most reliable ways to see this damage(5),(6). However, with outward
Iceland, the US and elsewhere. For the generation of electricity, hot water, at temperatures ranging from about 700 degrees F, is brought from the underground reservoir to the surface through production wells, and is flashed to steam in special vessels by release of pressure. The steam is separated from the liquid and fed to a turbine engine, which turns a generator. In turn, the generator produces electricity. Spent geothermal fluid is injected back into peripheral parts of the reservoir to help
Connections Between Neuroscience and the Theory of Multiple Intelligences: Implications for Education The old paradigm of students as empty vessels waiting to be filled with knowledge has given way to the constructivist belief that students continuously build understandings based on their prior experiences and information. The idea of a fixed intelligence has given way to a more flexible perception of gradual intellectual development dependent on external stimulation (6) Our intelligence, therefore
disagree with this outcome. On September 14, 1998, a team from Papworth Hospital in Cambridge England successfully demonstrated that red wine contains a high proportion of substances called polyphenols, which inhibit the deposit of fat in the blood vessels. These plant pigments tend to be a very strong antioxidant. Polyphenlos can be found in grape skins but they are discarded early in the process of making white wine. The study found that “red wine, but not white wine, has antioxidant activity … and
The Utopian Vision of Mother Teresa In August 1948, at the age of 38, Mother Teresa decided to adventure into the poorest neighborhoods of Calcutta, India, in order to live out her utopian dream by providing food, care, education, and shelter for the poor. Feeding people the Word of God; clothing them with dignity; educating them with knowledge, peace, truth, justice and love; nursing the mind and spirit; and sheltering them with a heart that understands. ("servants") I believe that a utopian
