Is American Culture a Harmless Invasion Essay Example | Topics and Well Written Essays - 250 words

Is American Culture a Harmless Invasion - Essay Example The author of the paper states that American troops may have been fighting against a country without an army for five years in Iraq to bring the culture of democracy to it, but the real victory has been the corporate invasion that has even managed to witness a company that has long used the advertising slogan related to how many hamburgers it has sold establish a footing in India, a country where the natural resource that provides beef is considered sacred. American culture is not a harmless invasion because it is even more successful actual battlegrounds attempting to enforce democracy upon foreign nations that are perhaps not quite ready to make that leap. Every town in American already looks like alike with its Wal-Marts, Burger Kings, Home Depots and Rave Motion Picture Theaters standing proudly as beacons of homogeneity in part because they displace the specific cultural touchstones of home-owned business. American culture is constructed upon a solid foundation of destroying the specific generational individualities of towns, cities, and regions. Monoculture is the real description of American culture because it is based upon a bland sameness in which every street in a town resembles every street in any other town.  Globalizing America’s monoculture threatens to do the same, and is there really anyone who wants to travel to London or Paris or Tokyo or Sydney and not be able to distinguish between those towns and Peoria or Las Cruces or Pittsburgh?  Ã‚

A Reflective Analysis on the Assessment and Management for ankle Essay - 1

A Reflective Analysis on the Assessment and Management for ankle injury - Essay Example The aim was not only to see the patient receiving the most suitable treatment for his condition, but also to consider such matters as how could he have been treated somewhat differently for an optimal outcome and how can similar injuries be prevented in the future. When considering this patient’s case reflectively the Gibbs model was chosen (1988). This well established model was chosen because it follows logically , and includes such things as evaluation and analysis, and also allows for the fact that the problem might recur, as is common in ankle injuries. The practitioner as they reflect, learn while doing. A patient in his early 20s walked in at the UCC with a contused left ankle. He said that he acquired the injury while playing soccer and the swelling and reaction present indicated that he was in great pain. The patient responded to questions in order to identify the cause of the injury, and the next cause of action. An ankle injury occurs when there is overstretching of ligaments beyond their ability, therefore causing a tearing (Stephens, Pait, & Sheehan, 2003). Following the OTTAWA ankle rules, not all ankle springs require XRAY, especially where there are no suspected fractures (McKeag & Moeller, 2007, p. 502). However, the clinician did make an exemption in this case because there was a swelling on the left ankle and the condition would not allow palpation of the bone. It was felt that if the patient had not continued playing at the initial stage when he first injured the ankle then there would not have been such swelling and the pain he was experiencing. Ankle sprain results from two situations; The inversion injury whereby the ankle turns inside as the ankle inverse and an injury due to external rotation (Buttaro, Trybulski, & Bailey, 2013 p.887). In order to determine the extent of the injury, which is a categorization the injury in a particular grade, a health practitioner carries out further

The Measurement And Instrumentation Engineering Essay

The Measurement And Instrumentation Engineering Essay A pyrometer is used to measure the temperature of an object from a distance, without making contact. The method used for making these non-contacting temperature measurements is known as radiation pyrometry. Non-contact temperature sensors use the concept of infrared radiant energy to measure the temperature of objects from a distance. After determining the wavelength of the energy being emitted by an object, the sensor can use integrated equations that take into account the bodys material and surface qualities to determine its temperature Pyrometer is derived from the Greek root pyro, meaning fire. The term pyrometer was originally used to denote a device capable of measuring temperatures of objects above incandescence, objects bright to the human eye. The original pyrometers were non-contacting optical devices which intercepted and evaluated the visible radiation emitted by glowing objects. A modern and more correct definition would be any non-contacting device intercepting and meas uring thermal radiation emitted from an object to determine surface temperature. Thermometer, also from a Greek root thermos, signifying hot, is used to describe a wide assortment of devices used to measure temperature. Thus a pyrometer is a type of thermometer. The designation radiation thermometer has evolved over the past decade as an alternative to pyrometer. Therefore the terms pyrometer and radiation thermometer are used interchangeably by many references. A radiation thermometer, in very simple terms, consists of an optical system and detector. The optical system focuses the energy emitted by an object onto the detector, which is sensitive to the radiation. The output of the detector is proportional to the amount of energy radiated by the target object (less the amount absorbed by the optical system), and the response of the detector to the specific radiation wavelengths. This output can be used to infer the objects temperature. The emittivity, or emittance, of the object is an important variable in converting the detector output into an accurate temperature signal. Pyro-Electric Pyroelectric detectors for thermal radiations are a relatively new form of pyrmometers. The construction material is usually ceramics are materials whose molecules have a permanent electric dipole because of the position of the electrons in molecules. Normally these molecules lie in a random mish-mash manner all across the bulk of the material hence there is no net electrification as a whole. Also, at ambient temperatures the location or orientation of these molecules is more or less fixed. If the temperature is raised above some level characteristic to the particular material, the molecules start to rotate freely. The temperature at which this start to happen is called the Curie temperature. When the pyroelectric surface is used as detector in a pyrometer, when the radiations from the source are absorbed by the pyroelectric material, its surface temperature increases .In the beginning the charge on the electrodes would be leaked away through the external electrical circuit and hence the measured voltage between the electrodes would be zero. When the pyroelectric surface heats up a voltage is detected between the two electrodes. As the temperature is further increased, further voltage is increased. Through this voltage value we can measure the temperature. The physical construction of a pyroelectric pyrometer is similar to the total radiation thermometer. C:UsersKKupusamyDesktopimages.jpg Pyroelectric linear arrays Photo electric A photoelectric pyrometer has been developed with which the International Practical Temperature Scale (IPTS) above the gold point, 1063  °C, is realized about 5 times more accurately than with the prevalently used disappearing filament visual pyrometer. Estimated standard deviation uncertainties of realizing the IPTS with the photoelectric instrument.An instrument that measures high temperatures by using a photoelectric arrangement to measure the radiant energy given off by the heated object. http://img.tfd.com/ggse/43/gsed_0001_0019_0_img5330.png Optical system of an automatic photoelectric pyrometer: Optical An optical pyrometer is a device which allows contactless temperature measuring by using the incandescense color. It is based upon the fact that all black bodies do have the same incandescense color at a given temperature. It is very straightforward and allows any temperature from which a hot object emits light ( > 500 deg C). It is made from a small magnifying optical device (like a monocular or very small telescope) in which a small incandescent bulb is placed which image is sharp when the user views through the eyepiece (the lens(es) on the eye end of the optical device). The background is the hot object to be gauged. The electrical current flowing through the filaments in the bulb is an indication of their temperature. This current is controlled by a potentiometer which is put between the power source (a battery) and the bulb. An ammeter is used to display the temperature. Its range is from 500 C (== 900F lower limit when an object incandesces) to 1600 C (3000 F), which is suitab le for most applications. http://www.pyrometer.com/NewFiles/Figure2.gif Typical temperature ranges for optical pyrometers Question 3 Electrocardiography (ECG) ECG (electrocardiogram) is a test that measures the electrical activity of the heart. The heart is a muscular organ that beats in rhythm to pump the blood through the body. The signals that make the hearts muscle fibers contract come from the sinoatrial node, which is the natural pacemaker of the heart. In an ECG test, the electrical impulses made while the heart is beating are recorded and usually shown on a piece of paper. This is known as an electrocardiogram, and records any problems with the hearts rhythm, and the conduction of the heart beat through the heart which may be affected by underlying heart disease. https://instruct1.cit.cornell.edu/courses/bionb440/FinalProjects/f2003/nwl2/Final%20Webpage/High-Level.JPG Block diagram of ECG What (Electrically) is being measured The measuring can be different with being different type conditions. Usually the some ECG will be recorded when the patient remain resting. But in some case as, some patients who having coronary heart disease symptoms, ECG will be taken while the doing exercise bike or treadmill. The electric waves in the heart are recorded in mill volts by the ECG. The waves are recorded by electrodes positioned on certain parts of the body. Each electrode controls an ink needle that writes on a grid paper. The higher the intensity of the electric wave, the higher up the needle will move on the paper. The paper moves at a certain speed beneath the needle, resulting in an ink curve. How is electric signal capture? How does it work? Amplifier The amplifier receives the electrical signals from the electrodes and converts the information. Because the bodys electrical signals are relatively weak, the amplifier must first stabilize the signal and then amplify by a factor of between five and 10. The amplifier is composed of several sections, including a buffer amplifier and preamplifier both of which work to convert the information received from the electrodes into information that is strong enough to be read by the output device. The amplifier is designed to receive information directly from the patient; however, it is also separate from the primary power circuits of the ECG machine.   What is the sensor? Measurement of the ECG signal gets challenging due to the presence of the large DC offset and various interference signals. This potential can be up to 300mV for a typical electrode. The interference signals include the 50-/60-Hz interference from the power supplies, motion artifacts due to patient movement, radio frequency interference from electro-surgery equipments, defibrillation pulses, pace maker pulses, other monitoring equipment, etc. Depending on the end equipment, different accuracies will be needed in an ECG: Standard monitoring needs frequencies between 0.05-30 Hz Diagnostic monitoring needs frequencies from 0.05-1000 Hz Some of the 50Hz/60Hz common mode interference can be cancelled with a high-input-impedance instrumentation amplifier (INA), which removes the AC line noise common to both inputs. To further reject line power noise, the signal is inverted and driven back into the patient through the right leg by an amplifier. Only a few micro amps or less are required to achieve significant CMR improvement and stay within the UL544 limit. In addition, 50/60Hz digital notch filters are used to reduce this interference further. http://produceconsumerobot.com/heartfeltapparel/content/7128.ecg.bmp Complete circuit of Block diagram Question 4 Vout = R3 (V2-V1) When Vout = 0, R1 0 = R3 (V2 1) R1 V2 = 1 When Vout = 10, Vout = R3 (V2 V1) R1 10 =R3(5 1) R1 10 = 4R3 R1 10R1=4R3 Let R1= 10Kà ¢Ã¢â‚¬Å¾Ã‚ ¦ 10 ÃÆ'- 10K= 4R3 R3 = 25Kà ¢Ã¢â‚¬Å¾Ã‚ ¦ R3 = R4 = 25Kà ¢Ã¢â‚¬Å¾Ã‚ ¦ R1 = 10 C:UsersRashydsAppDataLocalMicrosoftWindowsTemporary Internet FilesContent.WordNew Picture (2).bmp Question 5 Voltage to frequency The family of voltage-to-frequency converters ideally suitable for in simple low-cost-circuits for analog-to-digital conversion, precision frequency-to-voltage conversion, long-term integration, linear frequency modulation or demodulation, and many more. The output when used a voltage-to frequency converter is a pulse train at a frequency precisely proportional to the applied input voltage. Consequently, it provides all the inherent advantages of the voltage-to-frequency converter techniques, and easy to apply in all standard voltage-to-frequency converter application. Frequency and Voltage The tachometer uses a charge pump technique and offer frequency repetition for low wrinkle, full input protection in two versions and output swing to ground for a zero frequency input. The amplitude is fully well-matched with the tachometer and has a floating transistor as its output. This characteristic allows either a ground or supply referred load up to 50mA. This version is well suited for single speed or frequency switching or fully buffered frequency to voltage conversion application. Question 6 Orifice Plate An obstruction (orifice) is placed in a pipe filled with fluid. The pressure of the fluid is measured at two different points: 1) just upstream of the orifice and, 2) close to the contraction of the fluid (vena contracta). The difference in these two pressures is known as differential pressure. The differential pressure across an obstruction (orifice) in a pipe of fluid is proportional to the square of the velocity of the fluid. Many factors associated with the pipe, orifice and fluid affect the measurement. Satisfactory measurement requires steady-state, homogeneous, turbulent flowing fluids. Other properties which affect the measurement include: the ratio of pipe diameter to orifice diameter and the density, temperature, compressibility and viscosity of the fluid. http://www.spiraxsarco.com/images/resources/steam-engineering-tutorials/4/3/fig4.3.3.gif Venturi Meter Venturi has a long history of uses in many applications. Due to its simplicity and dependability, the Venturi is among the most common flowmeters. With no moving parts or abrupt flow restrictions, the Venturi can measure fluid flowrates with a minimal total pressure loss. The principle behind the operation of the Venturiflowmeter is the Bernoulli Effect. The Venturi measures a fluids flowrate by reducing the cross sectional flow area in the flow path and generating a pressure difference. After the pressure difference is generated, the fluid is passed through a pressure recovery exit section where up to 80% of the differential pressure generated at the throat is recovered. The pressure differential follows Bernoullis Equation. http://www.ustudy.in/imagebrowser/view/image/3463/_original Venturi meter Nozzle A NOZZLE IS A DUCT WHICH CONVERT HEAT ENERGY INTO KINETIC ENERGY.IT INCREASES VELOCITY OF FLUID PASSING THROUGH IT AT THE EXPENCE OF PRESSURE http://t1.gstatic.com/images?q=tbn:ANd9GcTTDTUwnq857efZrPN3mtwS-vIsRZ8OJxuVf1aPxsynFcrbaNuVCQ Pitot tube Pitot tube is used for measuring the stagnation within a channel, pipe or duct flow. Pitot tube is made in symmetrical body such as cylinder, cone, or hemisphere with drilled by the side of its central axis. If this is associated with its central axis in the direction of the flow the fluid will accelerate around the upstream face with less energy losses, and a stagnation point incline at the piezometric opening. Flow measurement using (a) Pitot tube, and (b) Pitot-static tube. Pitot tubes on aircraft commonly have heating elements called Pitot heat to prevent the tube from becoming clogged with ice.

Ambition By Moonlight - Original Writing :: Papers

Ambition By Moonlight - Original Writing The wind howled through Francis' mass of tatty black hair, that looked like a bird's nest, making it stream out behind him. He found it hard to keep his balance walking against the wind; it was like it was trying to lift him up and wisp him off, back to his warm welcoming house where he should be at this very moment. The long, thick grass was covered in frost; it looked like someone had sprinkled a thin layer of salt crystals across the field. It crunched under his feet, making Francis cringe, as he cautiously moved onwards, head bowed against the wind. He could feel the cold, deep down in his bones, despite wearing his thick trousers and fur coat. Suddenly he saw the last bit of the light from the village disappear in some shadows, Francis stopped abruptly and looked up slowly. First of all he noticed the old wooden signpost with its writing barely legible, craning his neck further he saw the mass of bare branches from the towering trees of the wood. The branches looked like frail hands and seemed to be trying to snatch him to haul him into the woods Francis was frozen in his step, transfixed by the woods in front of him, even though he could only see the very edge of the woods it still frightened him and made him jump at the slightest sound. Then all of a sudden the moon appeared bright in the sky from behind the clouds that appeared to have been swept aside by a large hand. It hung in the sky like bricks, lighting the field like a vast beacon. It was then Francis could have sworn he saw a small figure like that of a child, watching him, and appearing strangely familiar but he couldn't put his finger on whom it could be. Yet as quickly as he had seen it, it vanished, Francis shook his head telling himself he was just seeing things. Francis started to edge towards the woods, but just before he entered

Adam Smith :: Biography

Adam Smith The accumulation of capital and the division of labor are what Adam Smith believed to be the driving forces of economic growth in any nation. Smith found that when the division of labor had broken down the production of almost any commodity into a series of simple operations it was more natural for tools and machinery to be invented that replace hand labor and expedite the entire production process, thereby increasing worker productivity. This increased productivity combines with the growing capital stock to increse national output which enables society enjoy higher levels of consumption, constituting a genuine rise in the wealth of the nation according to Smith. Smith’s theory of economic growth can be formulated in a simple algerbraic equation. Where G equals the growth rate, K equals the ratio of productive to unproductive labor, P equals the productivity rate and W equals the real wage: G= KPW From this equation it becomes clear that for growth to occur, the product of the ratio of productive to unproductive labor and the productivity rate must increase more than the real wage. It would seem obvious that an easy way to do this would be to avoid any increase in the real wage, and indeed this view was accepted by many later classical economists who assumed that the nation had nothing to gain from an increase in wages. This was not Smith’s view at all. If an increase in capital enlarges the wages fund from which workers workers are paid, and if this increase is greater than the increase in the number of laborers, than it is only natural for the real wage to increase. On top of that Smith was a believer in what modern economists call the efficiency wage theories which hold that higher wages both enhance the vitality of the workers and reduce employee slacking and labor turnover, the latter two of which lower productivity and profitability. In the equation above it the product of K and P that is responsible for economic growth. It would appear then that K, the ratio of productive to unproductive labor, and P, the productivity rate are equally important factors in this determinance. However, Smith says that this is not so. The ratio of productive to unproductive labor does not change much over time, says Smith.

The social network where no one knows your name It’s a new social network called Social Number, lists users by a number, not by name. It's the latest and greatest thing in an ongoing debate about being online and anonymous. The CEO of the company sees it as a complement to open social networking. Users say they appreciate being able to talk freely without fear of being judged. You can discuss anything and everything. You have a message board that you post questions and other people on that website can respond to that thread.Social Number users say they find value in being able to openly talk about sensitive topics without worrying about alienating or offending anyone. You have a message board that you post questions and other people on that website can respond to that thread. I think this a good thing to have, where people can express their feelings without having feedback from other people that they know mainly so they don’t offend them. You can talk about how to deal with a bad boss, politics, jobs, friends, the ups and the downs of life al can be discussed here without having your name put on a social network.This is also good for people who want to vent and have other people’s opinion. Another good thing about this anonymous social network is that there is no bullying or threats. For some people expressing your political views on a social network will get attacked by people who are friends with them. As we all have a freedom of speech, I don’t believe that anyone should be ‘attacked’ because they have their own opinion. http://www. cnn. com/2013/01/29/tech/social-media/social-number-anonymous/index. html? hpt=li_c2
