Latin American Of The United States - 1426 Words

Online source, Diffen.com denotes that the term Hispanic is derived from the Latin word for Spain, while Latino is derived from Spanish word for Latin but which as an English word is probably a shortening of the Spanish word latinoamericano, which in English means Latin American. This term is used to denote the culture and people of countries formerly ruled by the Spanish Empire, usually with a majority of the population speaking the Spanish language (www.diffen.com). Commonly known as Hispanic America, this definition includes Mexico, the greater part of the Central and South American countries, and most of the Greater Antilles. The nations previously connected to the Spanish East Indies are sometimes freely incorporated in this definition, as their cultures have some Spanish or Latin American essentials. It was first adopted by the United States government during the Nixon administration and has been used in the U.S. Census since 1980 (WordIQ.com, 2015). The term Hispanic is to a great extent broadly and frequently used in states like Florida and Texas. Although both terms are used interchangeably, there is a difference between Hispanic and Latino. Hispanic is a term that originally referred to a relationship to ancient Hispania. Now it relates to the contemporary nation of Spain, its history, and culture. A citizen of Spain residing in the United States is a Hispanic. Latino refers more exclusively to persons or communities of Latin American origin.

compacing Facing it and Dulce et Decorum Essay - 1482 Words

â€Å"Facing it† by Yusef Komunyakaa and â€Å"Dulce et Decorum Est† by Wilfred Owen, are two powerful poems with the graphical life like images on the reality of war. It is apparent that the authors was a soldier who experienced some of the most gruesome images of World War I. In â€Å"Ducle et Decorum Est† Owen tells us about a personal experience in which he survived a chemical warfare attack. Although he survives, some of his fellow troops do not. As in â€Å"Facing It† Komunyakaa is also a soldier who has survived a war. Komunyakaa response to his war experience is deeply shaped by his visit to Lin’s memorial. Inspired by the monument, Komunyakaa confronts his conflicted feelings about Vietnam, its legacy, and even more broadly, the part race plays in†¦show more content†¦He struggles to internalize his emotions, telling himself he is stone, like the granite memorial, a strong and steady reminder of the past, but he fails as he realize s the difference between him and the memorial: he is a living human being. He shares the darkness, the blackness, with the granite memorial, yet he can feel the full impact of this connection whereas a granite memorial cannot itself feel the pain that it directly represents. The overall moral of the poems is fairly up front for the reader. It is that war is not how stories make it sound, it is not honorable and fun and glorious, it is gruesome, deadly, and changes the lives of many young men and women who still had a lot of life and innocence left in front of them, and now all they will have are the memories of death and their friends dying in front of them. As Komuyakaa face becomes clear it now serves as a direct reminder of the emotional impact of his surroundings upon him, through mirroring his own face and also by simultaneously illuminating his surroundings and his silhouetted existence within these surroundings, reminding him that he stands within the Vietnam Memorial. This e ffect is described within the (lines 8-13) His constant turning and moving from angle to angle also suggests emotion as he cannot view the

A Molybdenum Disulfide Piezoelectric Strain Gauge in Nanotechnology

Question: Explain the construction and operation of the eight transducers/sensors . Include a diagram for each, and explain how the measurement is converted into an electrical signal? Answer: Strain Gauge A strain gauge consists of all the flexible insulation which back-up to support the pattern of metallic foil. There has been a gauge which is attached to all the objects with a proper adhesive like cyanoacrylate. With deformation, the foil is completely deformed, which cause the resistance to change completely. The measure is done with the Wheatstone bridge, relating to the strains by a certain quantity which is said to be the gauging factor. Piezoelectric It has been working on the piezoelectric effect which can easily work on measuring the pressure change, acceleration, temperature, force, and strain by properly converting them into a charge of electricity. These are under the operational modes namely: Transverse Longitudinal Shear. Capacitive All the transducer of the capacitor with two parallel plates of metal have been separated with air and so they are said to be the dielectric material. In this, there is a capacitor which sets the distance between the plates, fixes, with a variable capacitance, variable between the two plates. Ultrasonic Active ultrasonic sensors are successful in generating a very high frequency for the sound waves which is evaluated by the echo and comes back by the sensors to measure the interval of time in the sending and the signal receiving time. The echo has been determined by the distance of the objects. All the ultrasonic passive sensors are completely based on the microphones which can easily detect the noise of the ultrasonic waves under the conditions to convert into electrical and report it to the computer system. Vortex The vortices has been completely detached from all the bluff body edges and have been forming into a fluid stream pattern. There have been distances set under the single vortices which is seen to be constant. All the changes in the frequency is depending upon the flow to pass a sensor which depends on the flowing rate as well the proportional flow. There has been a detection of sensor which can be easily converted into the frequency signal of electrical range. Coriolis Coriolis mass flowmeters have been able to properly measure the different forces which are set under the acceleration caused to handle the moving of mass towards or away from the center of rotation. All the amounts have been set under the twists which are said to be proportional to the flowing mass rate with the fluid passing through the tubes. There are sensors and a mass of Cariolis mass flowmeter which can easily transmit with the twists and the flow of signals. Resistance The resistances measures the temperature, which correlated to the elements of RTD along with temperature. There have been certain pure material, platinum, nickel and copper which has a complete change on temperature with the resistance. This is a predicted change for determining the temperature. Thermocouple It consists of different conductors which have been formed under the junctions of electrical form for different temperature. A thermocouple is able to product the temperature which is dependent on the voltage which is set under the thermoelectric effect to properly measure the temperature change. Strain Gauge It is used in the measurement of the building, foundation and development of structures. The different two halves are rigidly attaches with the foundation wall on the two sides and have been set under the red reference lines which consists of the transparent half and the other is the opaque white half. These have been able to set on the vertical and the horizontal movements for monitoring. Piezoelectric In this, these have been used to properly monitor the combustion and the development of the internal combustion engine. There have been sensors which attach to the mounts to additional handle the holes into head of cylinder and work towards the glowing plug, which is properly equipped with a miniature piezoelectric sensor, built inside. Capacitive Capacitive displacement sensors are used in the measurement of the object positioning to handle the nanometre level. There are precise positioning to conduct the semiconductor industry where there are wafers of silicon positioned under exposure. Ultrasonic Ultrasonic sensors have been used for the car parking to complete aid from reversing the cars. These are being tested under the different usages which includes the people detection of the ultrasonic along with assistance with the autonomous UAV navigation. Vortex In automotive applications, a complete change in the density of air works on changing temperature, altitude and the induction which is forced to handle the flow of mass which are appropriate for the flow sensors. It is important for properly determining the intake air for every cylinder. Coriolis The industries have been set under the higher to lower level sunder the chemical, food and beverage system. The mining and metals with the supply of the water and wastewater are worked under with proper quantity. Resistance Applications for the RTDs include There has been air conditioning and the service refrigeration The processing of food Grilling and stoves. Production of textile and processing plastics. Thermocouple Thermocouples have been properly used in the development of science and industry under the applications which measure the kilns, turbine gas exhaust with the diesel engines and processing the industrial changes. The signal conditioning has been based on the manipulation of the analog signal which are easily able to measure the requirement for processing. The conditioning is based on amplifications, filtering and properly converting the matching range with isolation and other processes. The conditioning, utilized under the data acquisition sets the data signals which could be normalized and work on the levels of filtering for converting from analog-to-digital flow of computerized devices. The entire transmission medium is based on the classification of: Linear medium, which is completely different under the waves with the medium that can be completely superposed. Bounded medium, works on finitely handling the unbounded medium; Uniform medium or homogeneous medium, is important for setting the physical properties with the unchanging points. Isotropic medium, with the physical properties difference at different direction. References: Hurst, A. M., Chenet, D., van der Zande, A., Kymissis, I., Hone, J. (2015, July).

Lyme Disease Essays (1204 words) - Medicine, Clinical Medicine, RTT

Lyme Disease Lyme Disease Lyme Arthritis ~~~~~~~~~~~~~~ Lyme disease is a tick-transmitted inflammatory disorder characterized by an early focal skin lesion, and subsequently a growing red area on the skin (erythema chronicum migrans or ECM). The disorder may be followed weeks later by neurological, heart or joint abnormalities. Symptomatology ~~~~~~~~~~~~~~ The first symptom of Lyme disease is a skin lesion. Known as erythema chronicum migrans, or ECM, this usually begins as a red discoloration (macule) or as an elevated round spot (papule). The skin lesion usually appears on an extremity or on the trunk, especially the thigh, buttock or the under arm. This spot expands, often with central clearing, to a diameter as large as 50 cm (c. 12 in.). Approximately 25% of patients with Lyme disease report having been bitten at that site by a tiny tick 3 to 32 days before onset of ECM. The lesion may be warm to touch. Soon after onset nearly half the patients develop multiple smaller lesions without hardened centers. ECM generally lasts for a few weeks. Other types of lesions may subsequently appear during resolution. Former skin lesions may reappear faintly, sometimes before recurrent attacks of arthritis. Lesions of the mucous membranes do not occur in Lyme disease. The most common symptoms accompanying ECM, or preceding it by a few days, may include malaise, fatigue, chills, fever, headache and stiff neck. Less commonly, backache, muscle aches (myalgias), nausea, vomiting, sore throat, swollen lymph glands, and an enlarged spleen may also be present. Most symptoms are characteristically intermittent and changing, but malaise and fatigue may linger for weeks. Arthritis is present in about half of the patients with ECM, occurring within weeks to months following onset and lasting as long as 2 years. Early in the illness, migratory inflammation of many joints (polyarthritis) without joint swelling may occur. Later, longer attacks of swelling and pain in several large joints, especially the knees, typically recur for several years. The knees commonly are much more swollen than painful; they are often hot, but rarely red. Baker's cysts (a cyst in the knee) may form and rupture. Those symptoms accompanying ECM, especially malaise, fatigue and low-grade fever, may also precede or accompany recurrent attacks of arthritis. About 10% of patients develop chronic knee involvement (i.e. unremittent for 6 months or longer). Neurological abnormalities may develop in about 15% of patients with Lyme disease within weeks to months following onset of ECM, often before arthritis occurs. These abnormalities commonly last for months, and usually resolve completely. They include: 1. lymphocytic meningitis or meningoencephalitis 2. jerky involuntary movements (chorea) 3. failure of muscle coordination due to dysfunction of the cerebellum (cerebellar ataxia) 4. cranial neuritis including Bell's palsy (a form of facial paralysis) 5. motor and sensory radiculo-neuritis (symmetric weakness, pain, strange sensations in the extremities, usually occurring first in the legs) 6. injury to single nerves causing diminished nerve response (mononeuritis multiplex) 7. inflammation of the spinal cord (myelitis). Abnormalities in the heart muscle (myocardium) occur in approximately 8% of patients with Lyme disease within weeks of ECM. They may include fluctuating degrees of atrioventricular block and, less commonly, inflammation of the heart sack and heart muscle (myopericarditis) with reduced blood volume ejected from the left ventricle and an enlarged heart (cardiomegaly). When Lyme Disease is contracted during pregnancy, the fetus may or may not be adversely affected, or may contract congenital Lyme Disease. In a study of nineteen pregnant women with Lyme Disease, fourteen had normal pregnancies and normal babies. If Lyme Disease is contracted during pregnancy, possible fetal abnormalities and premature birth can occur. Etiology ~~~~~~~~ Lyme disease is caused by a spirochete bacterium (Borrelia Burgdorferi) transmitted by a small tick called Ixodes dammini. The spirochete is probably injected into the victim's skin or bloodstream at the time of the insect bite. After an incubation period of 3 to 32 days, the organism migrates outward in the skin, is spread through the lymphatic system or is disseminated by the blood to different body organs or other skin sites. Lyme Disease was first described in 1909 in European medical journals. The first outbreak in the United States occurred in the early 1970's in Old lyme, Connecticut. An unusually high incidence of juvenile arthritis in the area led scientists to investigate and identify the disorder. In 1981, Dr. Willy Burgdorfer identified the bacterial spirochete organism (Borrelia Burgdorferi) which causes this disorder. Affected Population ~~~~~~~~~~~~~~~~~~~ Lyme Disease occurs in wooded areas with populations of mice and deer which carry ticks, and can be contracted during any season of the year. Related Disorders ~~~~~~~~~~~~~~~~~ Rheumatoid Arthritis is a disorder similar in appearance to
