    Nt1310 Unit 9

    A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for general lighting. Appearing as practical electronic components in 1962, early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.When a light-emitting diode is switched on, electrons are able to recombine with holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor. An LED is often small in area (less than 1 mm2), and integrated optical components may be used to shape its radiation pattern. LEDs have many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved physical robustness, smaller size, and faster switching. However, LEDs powerful enough for room lighting are relatively expensive, and require more precise current and heat management than compact fluorescent lamp sources of comparable output.Light-emitting diodes are used in applications as diverse as aviation lighting automotive lighting, advertising, general lighting, and traffic signals. LEDs have allowed new text, video displays, and sensors to be developed, while their high switching rates are also useful in advanced communications technology. Infrared LEDs are also used in the remote control units of many commercial products including televisions, DVD players and other domestic appliances. LEDs are also used in seven-segment display.…

    War of 1812 DBQ

    The War of 1812 was a war that lasted for two years that helped the United States to firmly and officially establish its independence. After finishing with the concern of France, England turned its attention over to the United States. At first, the United States did not want to resort to war and fighting (Doc. B) but rather sort out their issues economically--because England had seized all ships that did not stop in the British port before heading to their other European destinations, Congress passed the Embargo Act and then the Non-Intercourse Act, allowing trade with all nations except France and England. Then, England refused to allow this trade to occur, so America had to resort to war. The Northeastern Federalists were not in favor of war, but the Republicans ultimately won the majority vote in Congress to declare war--the War of 1812 (Doc. G). During this war, America was very concerned with gaining control over land in this country as well as in Canada, but at the same time Americans needed to defend themselves against their strong British enemies. Either way, America had to abandon its position of neutrality (Doc. C).…

    Prohibition

    Prohibition

    As America flourished with their newfound independence, taverns and drinking houses became the focal point of all ethnic neighborhoods. Immigrants felt comfortable in taverns; being surrounded by a common ethnicity, foreigners were free to converse in their native tongue and keep touch with their motherland. These pubs created a safe haven for people to unwind after a long week, while also generating revenue from the tax placed on liquor itself. Throughout the 19th century, a variety of different and ineffective (at the time) movements against alcohol surfaced across America. The temperance movement was brought to the society’s attention by the American Temperance Society, the Womens Christian Temperance Union (WCTU), the Anti-Saloon League, and Carrie Nation, causing nineteen states to ratify their constitutions and ban alcohol. . They used propaganda to compare the slave-trade to drunkenness, including their most popular quote: “A slave had lost control of his body, a drunkard lost control of his soul” (Rorabaugh 214). With the ratification of the 16th amendment (that created income taxes), the government no longer needed the liquor tax. This set the stage for the movement that eventually led to the ratification of the 18th Amendment, Prohibition.…

    Balancing Osmotic Pressure

    Balancing Osmotic Pressure

    The primary challenge of inhabiting a high salinity environment is balancing osmotic pressure. Since these environments contain high salt concentrations, water from the cells of organisms spontaneously diffuses out of the cytoplasm in order to restore osmotic balance. This leaves cells dehydrated and thus, eventually causes cell death. In order to ameliorate this predicament, halophiles use one of two unique strategies that function to increase the osmolarity of the cell, both of which as illustrated in figure 4. One strategy employs the accumulation from the environment or synthesis of organic compounds called compatible solutes in the cytoplasm of cells. These compatible solutes include polyalcohols, sugars, ectoines, betaines and amino acids.…

    A Cochlear Implant is a specialized hearing device that consists of both a surgically-implanted and external component used to simulate natural hearing. This device is used to treat people with severe and profound hearing loss. The implanted component is placed under the skin, behind the patient’s ear, and connected to the auditory nerve of the brain. The Cochlear Implants are designed to receive sounds and convert them into electrical signals that bypass the damaged nerves, allowing the brain to interpret the electrical signals.…
