Any movement by thehead, and this apparatus sends a signal to the brain so that your reflex actionis to move your foot to balance you.The ear in humans consist three parts The outer, the gist, and theinner portions. The outer ear, or pinna, is the structure that we call in the ear.It is the skin covered flap of elastic cartilage, that sticks out from the sideof the head. It acts like a funnel catching sound and sending it to the middleportion of the ear. The middle portion contains the ear drum and the connectionbetween the pharynx and the drum, the Eustachian tube. The inner ear containsthe sen sory receptors for hearing which are enclosed in a peregrine filled chambercalled the cochlea. The outer and middle ears purposes are only to receive andamplify sound. Those parts ofd the ear are only present in amphibians andmammals, precisely the inner ear is present in all vertebrates.The ear can hear in several different ways. They are volume, pitch, andtone. Pitch is related to the absolute frequency of the sound wave. The volume dependson the amplitude or intensity of the sound wave. The greater the frequency, thehigher the pitch. Humans can hear about 30 and 20,000 waves or cycles persecond. High pitch sounds produce more of a trebly sound, while low pitchsounds produce a rumbling bass sound.When a person loses these abilities to nab sound, it is referredto as deafness. It can be caused by disease, toxic drugs, trauma, or aninherited disorder. Those causes can be classified as conductive, sensorineural,or both.A conductive hearing loss results from damage to those parts o f the earwhich transmit sound vibrations in the air to the fluids of the inner ear. Thistype of damage is usually to the eardrum or polished bones known as ossicles.Ossicles conduct sound from the eardrum to the cochlea.

Desire in Herman Melville’s Moby-Dick Essay -- Moby Dick Essays

Desire in Herman Melvilles Moby-Dick Moby-Dick describes the metamorphosis of character resulting from the archetypal night sea journey, a harrow account of a withdrawal and a return. Thus Ishmael, the lone survivor of the Pequod disaster, requires three decades of voracious reading, spiritual meditation, and philosophical reflection before recounting his adventures aboard the ill-fated ship.1 His tale is astounding. With Lewis Mumfords seminal study Herman Melville A Critical Biography (1929) marking the advent of the Melville industry, attentive readersamateur and professional alike absorb reached consensus respecting the texts massive and heterogeneous structure. Moby Dick, for all its undeniable heuristic treasures, remains a taxonomists nightmare. For Melvilles complex narrative is an doubt of riches variously described as a novel, a romance, and an epic, as a comedy and a tragedy. Indeed, the text is an anatomy of the adventure story in the tradition of world classic accounts of the epic hero from Gilgamesh to the Arabian Nights, from the 0dyssey to Beowulf. Although from a formalist perspective Ishmael is clearly the sole narrator, the tale remains markedly divide in expression that is, the tone, diction, register, and underlying psychology of the account describe two radically different modes of experience. Ishmael in his own voice is empirical, democratic, sane, philosophical, comedic while Ahabs discourse is transcendental, autocratic, mad, rhetorical, tragic. Still, like Don Quixote and Sancho Panza (whose class, values, and mind set are separate and discrete) Ishmael, the common sailor before the mast, and Ahab, the demonic ship captain, finally emerge as disjoined fragment... ... 11 Zizek, 3. 12Zizek, ix.

What stops us from killing a disloyal friend or total other with nice shoes? Or ? to rephrase the question ? what fails to stop some people from committing such murders? This question has baffled psychologist, sociologists and criminologists for many years, and is the very essence of difficult to establish the nature of this crime. The born or made argument, known as the Nature versus Nurture debate, asks whether criminality is due to genetic factors, and therefore unavoidable, or whether it is the harvest-home of social situations, environmental surroundings or other external factors. While the debate is a noble one, we must first answer the question ?

The Black Panther Tank Battalion Essay -- essays research papers

The inexorable Panther Tank relative majorityThe 761st Black Panther Tank Battalion was the first African-American armored unit to see combat. in front and during mobilization for World War II, officials in Washington, D.C., debated whether or not African-American soldiers should be used in armored units. Many military men and politicians believed that blacks did not have the brains, quickness or moral stamina to fight in a war.Referring to his World War I experiences, Colonel James A. Moss, commander of the 367th understructure Regiment, 92nd Division, stated, "As fighting troops, the Negro must be rated as second-class material, this primarily to his inferior intelligence and lack of mental and moral qualities." Colonel Perry L. Miles, commander of the 371st Infantry Regiment, 93rd Division, flaccid a similar opinion "In a future war, the main use of the Negro should be in labor organizations." General George S. Patton, Jr., in a letter to his wife, wrote that "a colored soldier cannot think fast enough to fight in armor."The armed forces embraced these beliefs even though African Americans had fought with courage and distinction in the Revolutionary War and every other war and conflict ever waged by the United States. They overlooked the fact that four regiments of the 93rd Division had served with the French during World War I and that the French government had awarded the coveted Croix de Guerre to three of the four regiments and to a company of the fourth, as well as to the 1st Battalion, 367th Infantry Regiment, 92nd Division.Lieutenant General Leslie J. McNair, chief of the U.S. Army ground forces, was the main proponent of allowing African Americans to serve in armored units. He believed his nation could ill endure to exclude such a potentially important source of manpower. The black press, the National Association for the Advancement of Colored People, and the Congress of Racial Equality overly placed increasing pressu re on the War Department and President Franklin D. Roosevelts administration to allow black soldiers to serve on an equal footing with unclouded soldiers.In the summer of 1940, Congress passed into law the Selective Training and Service Act, which said, "In the selection and training of men under this act, there shall be no discrimination against any person on account of race and color." In October, howeve... ...17th Airborne Division. Assigned at various times to the Third, Seventh and Ninth armies, the Black Panthers fought major engagements in six European countries and participated in four major Allied campaigns. During that time, the unit inflicted 130,000 casualties on the German army and captured, destroyed or support in the liberation of more than 30 towns, several concentration camps, four airfields, three ammunition supply dumps, 461 wheeled vehicles, 34 tanks, 113 large guns, and thousands of individual and crew-served weapons. This was well-behaved in spite o f extremely adverse weather conditions, difficult terrain not suited to armor, heavily fortified enemy positions, extreme shortages of replacement personnel and equipment, an general casualty rate approaching 50 percent and the loss of 71 tanks.In 1978--33 years after the end of World War II--the 761st Tank Battalion received a Presidential Unit Citation. In 1997, 53 years after giving his life on the battlefield, Sergeant Ruben Rivers was posthumously awarded the Medal of Honor. The saying of the 761st Tank Battalion has always been "Come Out Fighting." In World War II, that is exactly what the Black Panthers did.
