Romanticism Movement Essay Example for Free

Romanticism Movement Essay Romanticism branched out of the age of humanism, and was an intellectual, literary, and mostly artistic movement that originated in Europe towards the end of the 18th century and at the beginning of the 19th century and was a revolt against the Neoclassicism which was popular in the previous centuries due to the Age of Enlightenment. The artistic movement rebelled against theoretical tradition. Many artists that participated in this movement drew inspiration from deep, emotional matters which they used as a foundation or starting point for many of their subjects and distinguished artistic styles. In shorter terms, the points that were emphasized in Romanticism were freedom, imagination, and of course emotion. Romanticism is therefore very much related to Realism in certain aspects. A German poet by the name of Friedrich Schlegel was credited for coining the term â€Å"romantic† which was used to describe literature in an â€Å"emotional matter in an imaginative form.† At the beginning of the 19th century, countries were experiencing, and going through many difficulties. Napoleon had ravaged many nations and had soaked their fields with much bloodshed. Europe however, was getting it the worst. The people living in Europe were dealing with crisis after crisis. Many were feeling lost, helpless, and generally miserable. There was absolutely no peace, and no order. It was most definitely a time for mourning and anguish. So at this point the Romanticism movement undoubtedly grew, as more people and artists focused on individualism, as opposed to life in society. Because many were individualists, they would obviously spend much time in the wilderness admiring nature then living in urban areas, thus nature was loved and worshipped by many romanticists. One can only imagine the various types of artwork that was produced because of this particular movement. There were more prominent figures or individuals that particularly stood out in the romantically artistic movement. One of these figures was a German Romantic landscape painter by the name of Caspar David Friedrich. He was born on September 5th 1774, and was known for his symbolic landscapes, and an overwhelming sense of loneliness in his paintings. His landscapes barely or rarely depicted sunlight, and rather they portrayed dense fog, mist or dawn. As he lost more friends and family to death, he would suffer depressive episodes. These episodes noticeably shifted the themes in his artwork, as he began to use graveyards, ruins, vultures and owls in many of his paintings, which symbolized and hinted at a looming, impending death. Friedrich is considered by many to be the â€Å"Edgar-Allen Poe† of art. Another pioneer of the Romantic movement was a influential French artist, painter, and lithographer know as Jean-Louis Andre Theodore Gericault. Initially, Gericault studied Neoclassicism at the Musee du Louvre but eventually found that his capacity to learn, or grow on this subject was lacking, so he left. Many of his paintings feature horses in them because he spent much time in the stables in Versailles studying the action and anatomy of horses. In is paintings he displayed graceful defeat, savagery, heroism, and of course animal magnificence. One of his most notable paintings is titled, â€Å"The Raft of the Medusa.† The painting reflected a French shipwreck which was called â€Å"Meduse,† of which its passengers were left to die by the ship’s captain. These however are just some of the distinguished artists that held a prominent role in the Romanticism movement. Though the American Revolution had taken place, and had their own Romanticism movement, France had been the hot zone when it came to this movement. France had been going through a revolution through out the time the movement was being advertised. As a matter of fact, the revolution seemed to be fueling the movement. This is evident in many pieces of Romantic literature, in which there are signs of effects caused by revolution. It is actually hinted that Romanticism in France was in fact the product of the effects of the revolution. The revolution inspired many Romantic writers, many of which were British, such as Percy Shelley, Lord Byron,William Wordsworth, Samuel Taylor Coleridge and many others, as they approved of the revolution and shared the same views regarding it. And though they all praised the revolution, they each had their own unique ideas regarding it, which can be studied or examined through their work. Furthermore, the movement had its own ideas in general about the overall revolution. When the revolt turned the entire nation in a new direction, many people used the freedom they had acquired to implement just laws to live and abide by, and they also had the freedom to think for themselves without having to be influenced by the society. Before the revolution, the work of artists, poets and writers chiefly dwelled on those who were high in social classes and religious leaderships. However that would soon change. Strengthened and encouraged by the revolution many writers and artists that had been holding in the will to express themselves were finally given the chance to under the new laws implemented by the population. Romanticism was a crucial movement during the French Revolution, as it helped many cope with the harsh lives they were living, and strike inspiration into the hearts of fellow Romantic pioneers. This movement also paved the way for Realism and as both discussed the depressive realities of life. â€Å"Some people call me sick and twisted. I feel that I’m neither; I am instead a Romantic.† -Kenzie Western Citations: http://www.goodreads.com/quotes/tag/romanticism http://www.uh.edu/engines/romanticism/introduction.html http://www.artchive.com/artchive/G/gericault.html http://www2.roguecc.edu/art/wpeterson/art206/romantic.html

Do Different Detergents Effect Plant Growth?

Do Different Detergents Effect Plant Growth? Somehow, though all life on earth has been created to be equally beautiful and unique in its own way, the plant kingdom is something that always has the most astounding of wonders, flowers that are synonymous with beauty, fields that personify heavenly scenery and gigantic trees that are only a minute reminder of natures infinite power, are just the beginning of a long list of the incredible sights that the green kingdom beholds. But as everything else in the world of today, these greeneries are also strongly hit by the one common and dramatically disastrous problem: POLLUTION! The contamination of the Air, the effluence of toxic waste in precious river and lake waters and toxic wastelands of precious soil deposits play pivotal roles in the degradation of these beautiful stores of life. Water pollution, however, is the hardest hitting of the lot, with effects ranging over a large span. The effects of water pollution are far-reaching and affect not only the environment, but human beings and animals as well. Water pollution affects our oceans, lakes, rivers, and drinking water, making it a widespread and global concern. Numerous diseases, health problems, and even fatalities have been associated with water pollution. Water is considered polluted when chemicals, pathogens, or contaminants are detected. Human beings have the most crucial impact on our water resources. They also have the ability to control or eliminate water pollution. Causes of Water Pollution Farmers often use chemicals to hinder bug infestations or other diseases from damaging or ruining their crops. They may also use chemicals to enhance the growth of their crops. Either way, these chemicals seep into the ground water or run off into lakes, creeks, or rivers, causing water pollution. Farmland that is irrigated and treated with chemicals in the form of fertilizers or pesticides is a major contributor to water pollution. Industrial processes produce toxic waste containing heavy metals. When heavy metals filter into water, they are fatal to marine life. Shellfish and fresh fish are staple menu items for people around the world. Humans are affected by the heavy metals ingested by the fish and shellfish, causing health problems and sometimes death. The heavy metals in water have also been linked to severe birth defects, a damaged or suppressed immune system, cancer, fertility problems, and developmental problems in children. The construction industry is the major fault for contaminating our water resources with cement, lubricants, plastics and metals. Rivers and lakes are also polluted from heavy silt or sediment run-off from construction sites. Ground water pollution occurs when chemicals, debris, garbage, oil or other harmful contaminants enter the ground water supply over time. Ground water is often a resource for our drinking water. If it isnt treated properly, those harmful elements can cause serious health issues for human beings and domestic animals. Natural catastrophes are the cause of water pollution effects as well. Major upheavals such as storms, earthquakes, acid rain, floods, and volcano eruptions have been known to disrupt the ecological system and pollute water. The growth of algae due to food items, feces, or urea in the water source is also a source of water pollution. When algae grow in water, it uses up more than its fair share of oxygen, causing other living organisms in the body of water to suffer. Certain types of algae can be fatal if they reach an algal bloom stage, otherwise known as brown or red tides. The process of contamination begins with tiny organisms called zooplankton and travels up the food chain through clams, birds, marine creatures, and ultimately, humans. These types of algae are considered toxic because they have been known to cause fatalities in humans. Even overgrowths of non-toxic types of algae can effectively block the sunlight from penetrating the waters surface, which makes it difficult fo r marine life to find food, causing eventual death. Littering on the land or on the water is a source of water pollution. Debris tossed onto land eventually makes its way into storm drains and then returns to surface water. Ships and boats discharging human waste or chemicals into the water directly are simply speeding up the pollution process. Industrial accidents that dump chemicals into the water kill marine life swiftly and within a short period of time. As the fish and plant life decompose, further water pollution occurs. Even sunken ships are a contributor to water pollution. As the ship corrodes and decays over time, those pieces of debris or chemicals are released into the ocean or freshwater lake. Once again, marine life is affected, which means humans who eat those fish or shellfish can be adversely harmed as well. Major Effects of Water Pollution The effects of water pollution are far-reaching and affect not only the environment, but human beings and animals as well. Water pollution affects our oceans, lakes, rivers, and drinking water, making it a widespread and global concern. Numerous diseases, health problems, and even fatalities have been associated with water pollution. Water is considered polluted when chemicals, pathogens, or contaminants are detected. Human beings have the most crucial impact on our water resources. They also have the ability to control or eliminate water pollution. The effects of water pollution are numerous. Some water pollution effects are recognized immediately, whereas others dont show up for months or years. Additional effects of water pollution include:  ·Ã¢â€š ¬Ã‚  Ã¢â€š ¬Ã‚  Ã¢â€š ¬Ã‚  The food chain is damaged. When toxins are in the water, the toxins travel from the water the animals drink to humans when the animals meat is eaten.  · Diseases can spread via polluted water. Infectious diseases such as typhoid and cholera can be contracted from drinking contaminated water. This is called microbial water pollution. The human heart and kidneys can be adversely affected if polluted water is consumed regularly. Other health problems associated with polluted water are poor blood circulation, skin lesions, vomiting, and damage to the nervous system. In fact, the effects of water pollution are said to be the leading cause of death for humans across the globe.  · Acid rain contains sulfate particles, which can harm fish or plant life in lakes and rivers.  · Pollutants in the water will alter the overall chemistry of the water, causing changes in acidity, temperature and conductivity. These factors all have an effect on the marine life.  · Marine food sources are contaminated or eliminated by water pollution.  · Altered water temperatures (due to human actions) can kill the marine life and affect the delicate ecological balance in bodies of water, especially lakes and rivers. Our main aim is to reproduce our polluted environment by scaling it down to using instruments which are practical and feasible enough to use in any laboratory. Explanation of Research Question Do different concentrations of different detergent affect the growth of root and shoot in Vigna Radiata (Mung bean)? This question mainly addresses the topic of stunted growth of plants. Different detergents contain various powerful surfactants such as sodium dodecyl sulfate. These detergents characteristically aggregate lipids and denature proteins. When detergents are absorbed by a plant, the detergents can cause cell membranes to collapse and membranes to function improperly. This can cause part or all of a plant to die. Depending on the various concentrations of these pollutants, the plant shows different levels of growth, ascending from the least growth in the most concentrated of solutions (0.5%) to the highest in pure distilled water. Our main aim, under this research question, is to find out the trends in growth affection of plants that are subjected to these detergents.

Detergents were first produced in Germany about the beginning of World War I. Plants are one of four families in scientific classification. They differ from animals in that they have chlorophyll and cell walls in their cells. Detergent is defined as a cleansing substance that acts similarly to soap but is made from chemical compounds rather than fats and lye. By the American Heritage Dictionary of the English Language. Modern detergents contain a chemical called a surfactant, which, defined by Word Net 1.6 is A substance capable of reducing the surface tension of a liquid in which it is dissolved. This allows the detergent to spread further, penetrate better and clean much more efficiently. With the addition of builders, which make the surfactants work much better. Detergents are used mainly for four different things: personal cleansing, laundry, dish washing and house cleaning. Detergent Popularity Detergents are far from being as old as soap, but today they are the best selling method of washing clothes and dishes. Detergent popularity has grown exponentially since around 1950. In between 1940 and 1972 the sales of detergents went from about 4,500 tons per year to around 4,448,000 tons per year. Detergents, as was stated, were first seen around the beginning of W.W.I. The exact year is 1916. They were first used Because of the war related shortage of fats. It was sold under the general name Nekal. The discovery of detergents was in part because the people where looking for a cleaning substance, that, unlike soaps, would not mix with the minerals in water to make a wax like residue called soap curd. They were not as high quality detergents as we have now, and were used mostly as wetting agents in textile work. The quality didnt change much in the 20s and 30s, with only minor enhancements. The sales for detergents really skyrocketed around the beginning of W.W.II, with a shortage of fats and oils needed to produce soap. The military badly needed a cleaning agent that wouldnt mix with the mineral rich waters to make soap curd. The breakthrough came at the end of the war in 1946. Up to then detergents were used for hand dish washing and washing sensitive clothing. The first all- purpose laundry detergent had surfactants and builders. The builders greatly improved the efficiency of the surfactants. By the end of 1950, soaps had almost been forgotten as a way to wash clothes and dishes, but were still used at the same time as detergents. Through the years, detergents have changed a lot. In the 50s detergents were used in dishwashers and for the laundry. They were adapted to be bleaches. Fabric softeners were also developed. In the 70s they manufactured liquid hand soap. In the 80s they made liquid dishwasher detergent, detergents for colder water washing and concentrated detergents. In the 90s they manufactured super-concentrated detergents and dishwasher gels. Detergents used: To counterfeit the pollution of natural water environments, we will use two different detergents, both of which use surfactant molecules, these have two parts. One is water loving and the other is water hating. The water-loving (hydrophilic) part breaks the surface tension of water. The water-hating (hydrophobic) part is attracted to oil and grease in soils, loosening and removing them from fabrics. Detergents usually contain more than one type of surfactant to address the needs of removing certain types of soils and cleaning different types of fabrics. The Mung bean is the name of the seed of Vigna radiata, an ovoid, greenish brown dicot which is native to parts of Bangladesh, Pakistan and India. The mung bean is one of many species recently moved from the genus Phaseolus to Vigna and is still often seen cited as Phaseolus aureus or Phaseolus adiates. These variations of nomenclature have been used regarding the same plant species. Plant Taxonomy Kingdom: Plantae Division: Magnoliophyta Class: Magnoliopsida Order: Fabales Family: Fabaceae Genus: Vigna Species: V. radiata History of Plant Originally from Asia, the Chinese have been growing mung bean sprouts (Nga choy or Nga choi) for approximately 3,000 years. Farmers grow them often with little machinery. After harvest they are left to dry on gravel roads. So the dust and dirt on your mung beans that you buy from the store is actually from a road in China. Today China and India are the main producers of mung beans; it is also grown in Australia. The mung is also popular in the Philippines where they call it Munggo. Climate and Soil Mung beans are mainly cultivated in China, Thailand, Philippines, Indonesia, Burma, Bangladesh and India, but also in hot and dry regions of South Europe and Southern USA. In India and Bangladesh, they are grown during two seasons. One is the Rabi season (starting November), and the other is the Kharif season (starting June). Mung beans are tropical (or sub-tropical) crops, and require warm temperatures (optimally round 30-35 °C). Loamy soil is best for pusap cultivation. Nutritional Values Mung beans are a good source of Vitamins A, B, C E, calcium, iron, magnesium, potassium, and amino acids. Mung beans contain 20% protein and are a good source of foliate and dietary fibre. Variables: Control Amount of sunlight received by seeds Levels of Oxygen and Carbon di-oxide supplied to seeds Species of viable seeds Temperature Amount of Solution use Independent The concentration of detergents in solution (0.1% to 0.5%) Dependent The length of the shoot in Vigna radiata (in cms) The length of the root in Vigna radiata (in cms) Procedure: Cover the base of 11 different petri dishes with cotton (10 + 1 control) Mark the petri dishes according to the percentage concentration of detergent in each (From 0.1% -0.5%) Separate the petri dishes according to the detergent used, 5 with Surf Excel, 5 with Tide powder and one control dish with distilled water. Place an equal number of Vigna Radiata seeds in each petri dish (10) Ensure equal amounts of sunlight and carbon di-oxide levels to each petri dish. Tend to the seeds for 10 days and calculate root and shoot growth of seeds in all concentrations at the end of that period.

A military technology

A military technology CDMA is a military technology first used during World War II by English allies to foil German attempts at jamming transmissions. The allies decided to transmit over several frequencies, instead of one, making it difficult for the Germans to pick up the complete signal. Because Qualcomm created communications chips for CDMA technology, it was privy to the classified information. Once the information became public, Qualcomm claimed patents on the technology and became the first to commercialize it. Code Division Multiple Access technology emerged as an alternative to the GSM cellular architecture and has shared in the past decades explosive growth in the wireless market. CDMA, like GSM, has seen incremental improvements in capacity throughout this period. Now both types of networks are making a transition to third-generation (3G) systems around the globe, offering yet more capacity and data services. INTRODUCTION With the advent of wireless communication there was the advent of the two technologies for the cellular communication. They were the CDMA and the GSM technology. Both the technologies have their own mechanisms of working and their own pros and cons for which they have their own different utilizations and implications.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The technology on which our group has proposed to research is the CDMA (Code Division Multiple Access) technology. Though the total users of the CDMA technology around the globe are approximately 14% yet it has many advantages over the GSM technology which has enormous number of users. Actually the GSM technology is easy to manage and to handle rather than CDMA but that doesnt mean that it has got no future. Truly speaking the CDMA technology is the technology of the future. Gradually its gaining popularity in the European market. What is CDMA? CDMA (Code-Division Multiple Access) refers to any of several protocols used in so-called second-generation (2G) and third-generation (3G) wireless communications. As the term implies, CDMA is a form of multiplexing, which allows numerous signals to occupy a single transmission channel, optimizing the use of available bandwidth. The technology is used in ultra-high-frequency (UHF) cellular telephone systems in the 800-MHz and 1.9-GHz bands. CDMA employs analog-to-digital conversion (ADC) in combination with spread spectrum technology. Audio input is first digitized into binary elements. The frequency of the transmitted signal is then made to vary according to a defined pattern (code), so it can be intercepted only by a receiver whose frequency response is programmed with the same code, so it follows exactly along with the transmitter frequency. There are trillions of possible frequency-sequencing codes, which enhance privacy and makes cloning difficult. The CDMA channel is nominally 1.23 MHz wide. CDMA networks use a scheme called soft handoff, which minimizes signal breakup as a handset passes from one cell to another. The combination of digital and spread-spectrum modes supports several times as many signals per unit bandwidth as analog modes. CDMA is compatible with other cellular technologies; this allows for nationwide roaming. The original CDMA standard, also known as CDMA One and still common in cellular telephones in the U.S., offers a transmission speed of only up to 14.4 Kbps in its single channel form and up to 115 Kbps in an eight-channel form. CDMA2000 and wideband CDMA deliver data many times faster. Code Division Multiple Access (CDMA) is a digital air interface standard, claiming eight to fifteen times the capacity of traditional analog cellular systems. It employs a commercial adaptation of a military spread-spectrum technology. Based on spread spectrum theory, it gives essentially the same services and qualities as wireline service. The primary difference is that access to the local exchange carrier (LEC) is provided via a wireless phone. Though CDMAs application in cellular telephony is relatively new, it is not a new technology. CDMA has been used in many military applications, such as: Anti-jamming (because of the spread signal, it is difficult to jam or interfere with a CDMA signal). Ranging (measuring the distance of the transmission to know when it will be received). Secure communications (the spread spectrum signal is very hard to detect). CDMA is a spread spectrum technology, which means that it spreads the information contained in a particular signal of interest over a much greater bandwidth than the original signal. With CDMA, unique digital codes, rather than separate RF frequencies or channels, are used to differentiate subscribers. The codes are shared by both the mobile station (cellular phone) and the base station, and are called pseudo-random code sequences. Since each user is separated by a unique code, all users can share the same frequency band (range of radio spectrum). This gives many unique advantages to the CDMA technique over other RF techniques in cellular communication. CDMA is a digital multiple access technique and this cellular aspect of the protocol is specified by the Telecommunications Industry Association (TIA) as IS-95. In CDMA, the BSSAP is divided into the DTAP and BSMAP (which corresponds to BSSMAP in GSM). Generating a CDMA signal There are five steps in generating a CDMA signal. analog to digital conversion vocoding encoding and interleaving channelizing the signals conversion of the digital signal to a Radio Frequency (RF) signal The use of codes is a key part of this process. How CDMA is altering the face of cellular and PCS communication? CDMA is altering the face of cellular and PCS communication by: Dramatically improving the telephone traffic capacity Dramatically improving the voice quality and eliminating the audible effects of multipath fading Reducing the incidence of dropped calls due to handoff failures Providing reliable transport mechanism for data communications, such as facsimile and internet traffic Reducing the number of sites needed to support any given amount of traffic Simplifying site selection Reducing deployment and operating costs because fewer cell sites are needed Reducing average transmitted power Reducing interference to other electronic devices Reducing potential health risks Commercially introduced in 1995, CDMA quickly became one of the worlds fastest-growing wireless technologies. In 1999, the International Telecommunications Union selected CDMA as the industry standard for new third-generation (3G) wireless systems. Many leading wireless carriers are now building or upgrading to 3G CDMA networks in order to provide more capacity for voice traffic, along with high-speed data capabilities. CDMA is a form of Direct Sequence Spread Spectrum communications. In general, Spread Spectrum communications is distinguished by three key elements: The signal occupies a bandwidth much greater than that which is necessary to send the information. This results in many benefits, such as immunity to interference and jamming and multi-user access, which well discuss later on. The bandwidth is spread by means of a code which is independent of the data. The independence of the code distinguishes this from standard modulation schemes in which the data modulation will always spread the spectrum somewhat. The receiver synchronizes to the code to recover the data. The use of an independent code and synchronous reception allows multiple users to access the same frequency band at the same time. In order to protect the signal, the code used is pseudo-random. It appears random, but is actually deterministic, so that the receiver can reconstruct the code for synchronous detection. This pseudo-random code is also called pseudo-noise (PN). There are three ways to spread the bandwidth of the signal: Frequency hopping. The signal is rapidly switched between different frequencies within the hopping bandwidth pseudo-randomly, and the receiver knows before hand where to find the signal at any given time. Time hopping. The signal is transmitted in short bursts pseudo-randomly, and the receiver knows beforehand when to expect the burst. Direct sequence. The digital data is directly coded at a much higher frequency. The code is generated pseudo-randomly, the receiver knows how to generate the same code, and correlates the received signal with that code to extract the data. HOW SPREAD SPECTRUM WORKS? Spread Spectrum uses wide band, noise-like signals. Because Spread Spectrum signals are noise-like, they are hard to detect. Spread Spectrum signals are also hard to Intercept or demodulate. Further, Spread Spectrum signals are harder to jam (interfere with) than narrowband signals. These Low Probability of Intercept (LPI) and anti-jam (AJ) features are why the military has used Spread Spectrum for so many years. Spread signals are intentionally made to be much wider band than the information they are carrying to make them more noise-like. Spread Spectrum signals use fast codes that run many times the information bandwidth or data rate. These special Spreading codes are called Pseudo Random or Pseudo Noise codes. They are called Pseudo because they are not real Gaussian noise. Spread Spectrum transmitters uses similar transmit power levels to narrow band transmitters. Because Spread Spectrum signals are so wide, they transmit at a much lower spectral power density, measured in Watts per Hertz, than narrowband transmitters. This lower transmitted power density characteristic gives spread signals a big plus. Spread and narrow band signals can occupy the same band, with little or no interference. This capability is the main reason for all the interest in Spread Spectrum today. IMPLEMENTATION OF CDMA TECHNOLOGY Now a day, in large organization the communication process has to be fast and efficient. There are the major points that have to be taken care in the modern corporate culture. Over time, more and more demands have been made on the capabilities of corporate networks. Workers want more mobility; secure, high-speed access; and an extension of applications across the enterprise, all of which can strain current IT capabilities. The first and foremost of all is protecting corporate network assets is an ongoing task for IT professionals. Increased worker mobility and mobile workers needs for immediate, secure access to critical business information add challenges to maintaining network security Some of todays top security issues and concerns are: Unauthorized systems and network access Auditability and compliance Customer data breaches Internal and external sabotage Theft of intellectual property and confidential business information Cost of mobile device administration The following diagram illustrates many elements critical to mobile data security. DIFFERENCE BETWEEN GSM AND CDMA TECHNOLOGY In cellular service there are two main competing network technologies: Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA). Cellular carriers including Sprint PCS, Cingular Wireless, Verizon and T-Mobile use one or the other. Understanding the difference between GSM and CDMA will allow you to choose a carrier that uses the preferable network technology for your needs. The GSM Association is an international organization founded in 1987, dedicated to providing, developing, and overseeing the worldwide wireless standard of GSM. CDMA, a proprietary standard designed by Qualcomm in the United States, has been the dominant network standard for North America and parts of Asia. However, GSM networks continue to make inroads in the United States, as CDMA networks make progress in other parts of the world. There are camps on both sides that firmly believe either GSM or CDMA architecture is superior to the other. That said, to the non-invested consumer who simply wants bottom line information to make a choice, the following considerations may be helpful. Coverage The most important factor is getting service in the areas you will be using your phone. Upon viewing competitors coverage maps you may discover that only GSM or CDMA carriers offer cellular service in your area. If so, there is no decision to be made, but most people will find that they do have a choice. Data Transfer Speed With the advent of cellular phones doing double and triple duty as streaming video devices, podcast receivers and email devices, speed is important to those who use the phone for more than making calls. CDMA has been traditionally faster than GSM, though both technologies continue to rapidly leapfrog along this path. Both boast 3G standards, or 3rd generation technologies. EVDO, also known as CDMA2000, is CDMAs answer to the need for speed with a downstream rate of about 2 megabits per second, though some reports suggest real world speeds are closer to 300-700 kilobits per second (kbps). This is comparable to basic DSL. As of fall 2005, EVDO is in the process of being deployed. It is not available everywhere and requires a phone that is CDMA2000 ready. GSMs answer is EDGE (Enhanced Data Rates for GSM Evolution), which boasts data rates of up to 384 kbps with real world speeds reported closer to 70-140 kbps. With added technologies still in the works that include UMTS (Universal Mobile Telephone Standard) and HSDPA (High Speed Downlink Packet Access), speeds reportedly increase to about 275à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬380 kbps. This technology is also known as W-CDMA, but is incompatible with CDMA networks. An EDGE-ready phone is required. In the case of EVDO, theoretical high traffic can degrade speed and performance, while the EDGE network is more susceptible to interference. Both require being within close range of a cell to get the best speeds, while performance decreases with distance. Subscriber Identity Module (SIM) cards In the United States only GSM phones use SIM cards. The removable SIM card allows phones to be instantly activated, interchanged, swapped out and upgraded, all without carrier intervention. The SIM itself is tied to the network, rather than the actual phone. Phones that are card-enabled can be used with any GSM carrier. The CDMA equivalent, a R-UIM card, is only available in parts of Asia but remains on the horizon for the U.S. market. CDMA carriers in the U.S. require proprietary handsets that are linked to one carrier only and are not card-enabled. To upgrade a CDMA phone, the carrier must deactivate the old phone then activate the new one. The old phone becomes useless. Roaming For the most part, both networks have fairly concentrated coverage in major cities and along major highways. GSM carriers, however, have roaming contracts with other GSM carriers, allowing wider coverage of more rural areas, generally speaking, often without roaming charges to the customer. CDMA networks may not cover rural areas as well as GSM carriers, and though they may contract with GSM cells for roaming in more rural areas, the charge to the customer will generally be significantly higher. International Roaming If you need to make calls to other countries, a GSM carrier can offer international roaming, as GSM networks dominate the world market. If you travel to other countries you can even use your GSM cell phone abroad, providing it is a quad-band phone (850/900/1800/1900 MHz). By purchasing a SIM card with minutes and a local number in the country you are visiting, you can make calls against the card to save yourself international roaming charges from your carrier back home. CDMA phones that are not card-enabled do not have this capability, however there are several countries that use CDMA networks. Check with your CDMA provider for your specific requirements. According CDG.org, CDMA networks support over 270 million subscribers worldwide, while GSM.org tallies up their score at over 1 billion. As CDMA phones become R-UIM enabled and roaming contracts between networks improve, integration of the standards might eventually make differences all but transparent to the consumer. The chief GSM carriers in the United States are Cingular Wireless, recently merged with ATT Wireless, and T-Mobile USA. Major CDMA carriers are Sprint PCS, Verizon and Virgin Mobile. There are also several smaller cellular companies on both networks.

Sniper Coward or Hero :: essays papers

Sniper Coward or Hero Since the invention of the firearm, skilled individuals with specialized equipment have influenced the ebb and flow of the battlefield. At times this influence has been so great as to turn the tide of history. The long-range sharpshooter or sniper has had a telling effect on the direction, drive, and scope of battle. The sniper has felled the command structure of his enemies, rendered their equipment useless, and driven fear into the heart of the men. Thus, the sniper is one of the most effective weapons on the field of battle. A true sniper is an operative who gathers intelligence for the command structure and occasionally takes the one, well-aimed shot that, if done properly, will save lives. In order to better understand exactly how snipers are valuable, one needs to consider their mission, training, and equipment. The sniper^s primary mission is to deliver long range, precision fire on key targets and targets of opportunity. His secondary mission is the collection and reporting of information. Both missions are very specific and dangerous. To carry out these missions, a sniper must be highly trained in marksmanship and field craft skills to ensure maximum effectiveness with minimum risk (Lanning 88-100). The U. S. Army Sniper School is five weeks of intense training. Before a student can even be considered for attendance to sniper school, he must meet stringent qualifications and pass a mental examination. Classes are usually small, but have a high failure rate. The first week consists of physical training and classroom instruction, concentrating on the construction of a Ghillie Suit, which is a special hand made form of camouflage (Sasser 215). The second, third, and fourth weeks are composed of practical exercises and tests covering everything taught during week one. Emphasis is placed on developing stalking skills. Stalking is the term used when a sniper maneuvers into his final firing position (Lanning 159). After the fourth week and all the field orientated tests have been completed, the students that are left, participate in a four day field training exercise which is run as a real life mission. The students form two-man teams. One is the sniper and the other is his spotter. The spotter^s main function is to observe a target and provide data to the shooter. The spotter must also be fully sniper qualified and trained to carry out the mission. The team receives an operation order, which explains its first mission or objective. The team must then plan its

The Impact of Negro Spirituals on Todays Music Essay -- Exploratory E

The Impact of Negro Spirituals on Today's Music I believe that it would be difficult for someone to make the argument that Negro spirituals have not been influential in the field of music, much less the realm of gospel music today. However, church members often do not make the time to reflect on the heritage of a hymn or song to realize the meaning that the particular piece has carried with it through the decades, even centuries. With this in mind, I am going to look at the history of the Negro spiritual and then at specific hymns in the 1991 Baptist Hymnal, published by Convention Press, to see just what impact the Negro spiritual has had on today's church music. I believe that we will find that these songs have had a significant affect on our music, and that without it, we would not have many of the hymns that are now considered standard church music. An important observation regarding African music comes from Richard Jobson in The Golden Trade or a Discovery of the River Gambra [Gambia] and the Golden Trade of the Aethiopians. Although published in 1623, we learn a lot about the nature of African music when we read: "There is without a doubt, no people on the earth more naturally affected to the sound of musicke than these people; which the principal persons [that is, the kings and chiefs] do hold as an ornament of their state, so as when wee come to see them their musicke will seldome be wanting" (qtd. in Southern 4). By understanding that music was of utmost importance to the original slaves, we understand how the reverence of music was handed down through the many generations of slaves on the plantations. It is apparent that music was the highest form of expression for Africans, as well as... ...ital Schomburg African American Women Writers in the 19th Century Works Consulted Fisher, Miles Mark.

Unemployment :: Working Jobs Careers Labor Essays

Unemployment In compiling unemployment statistics for the United States and other developed countries an unemployed person is defined as anyone who is capable of working and is actively seeking work but is unable to find a job.1Before a person can be unemployed in this sense he must be an active member of the labor force in search of a job. Students and Homemakers perform work, but they are not considered employed unless they are paid; however, they are not considered unemployed unless they are actively seeking gainful jobs. In societies in which a majority of the citizens are able to earn a living by working for others, being unable to locate and obtain a job is a very serious problem. Unemployment is widely used as a measure of workers' welfare because of the human costs and feelings of rejection and personal failure. The proportion of workers unemployed also shows how well a nations human resources are used and serves as an index of economic activity. The civilian labor force comprises the total of all civilians classified as employed or unemployed. The total labor force also includes members of the Armed Forces stationed either in the US Or abroad. The unemployment rate represents the number unemployed as a percent of the civilian labor force.2 Unemployment can be divided percent of the civilian labor into three types known as frictional, structural, and cyclical. The first form of unemployment is frictional unemployment. Frictional unemployment arises because workers seeking jobs do not find them immediately. While looking for work they are counted as unemployed.3 This could happen if suppose a person loses a job, perhaps because the work is finished. For example a construction craftsman when the job is finished; or it could happen to an actor or actress when the show closes. It will ordinarily take some time before that person finds another job. But while construction workers and entertainers can ordinarily expect to face this problem from time to time, it is something that can happen to anyone employed. People who are simply between jobs, in this sense, are said to be frictionally unemployed. The amount of frictional unemployment depends on the frequency with which workers change jobs and the time it takes to find new on es.4 This is a particularly important category, since this category of unemployment can never be eliminated or reduced to zero. Even in the best functioning market economy, there will be some people who are between jobs.

Mina Loy’s poem “Lunar Baedeker” Essay

When read top to bottom, Mina Loy’s poem â€Å"Lunar Baedeker† may sound like a story of drugs, sex, and desperation. In reality, it is an encrypted biography of part of Loy’s life, as well as symbolic of the cycles of life. Let’s start with the title, shall we? â€Å"Lunar Baedeker,† the word ‘lunar’ means moon. It can also mean relating to the moon, but more importantly it can mean measured by the moon’s cycles. What in the world is a â€Å"Baedeker† though? Baedeker is actually one Karl Baedeker, a German who, in 1859, published a series of guidebooks. Mina Loy’s title, therefore, translates to either â€Å"a guide to the moon† or a † a guide to the moon’s cycle or cycles.† The first stanza is very autobiographical; it refers to Loy’s falling in love with her second husband, Fabien Avernarius Lloyd, also known as Arthur Cravan. â€Å"A silver Lucifer/ serves/ cocaine in cornucopia† Silver here can be read as a shiny, white color, or highly persuasive, or a metal that has the highest thermal and electrical conductivity. Lucifer can mean a fallen rebel or a fallen star. If you read ‘Lucifer’ as ‘star’ it fits in well with Loy’s celestial theme, but it is better construed as a fallen rebel, because Loy’s second husband, Cravan, was constantly on the run for being a draft dodger. The fact that he was silver describes him as beautiful, pure, and persuasive. The fact that silver has the highest thermal and electrical conductivity says that he had a lot of sex appeal and â€Å"sparks flew† between him and the poet. Cocaine is a highly addictive substance that causes euphoric effect. The fact that it is â€Å"served . . . in cornucopia† makes Loy sound very much like a young girl who is giddy with love and cannot get enough of her beau. A rendition of the couple’s bedroom life is in the next stanza: â€Å"To some somnambulists/ of adolescent thighs/ draped/ in satirical draperies† Though Loy has two children from a previous marriage, these lines make Loy sound like a virgin in her husband’s bed. The term ‘somnambulists’ means sleepwalkers, which keys you into this pertaining to night activities. Thighs are a common representation of sexuality, as they are so close to the sex organs anyway, and by describing what I assume are Loy’s own thighs as  Ã¢â‚¬Å"adolescent† she represents her own sexuality as immature, underdeveloped, vulnerable and unused. By being â€Å"draped/ in satirical draperies† Loy says that her immaturity is hidden, but only by clothing or cloth that intentionally exposes and criticizes her puerility. Loy’s third child, Fabienne, is referred to in the third stanza. â€Å"Peris in livery/ prepare/ Lethe/ for posthumous parvenus† Peris, which is not ‘Paris’ misspelled, is actually the plural form of the noun Peri. A Peri is a woman or girl who is descended from fallen angels and is excluded from Paradise. The term can also be used to describe a beautiful girl. Livery is servants’ clothing, implying that this ‘Peri’ is not from a wealthy family. Lethe is the river in Hades that would erase one’s memories if she were to drink from it. The ‘posthumous parvenues,’ however, is what ties this whole stanza into Fabienne. Loy’s husband, Cravan, married his wife in Mexico where he was dodging the draft. They separated and were supposed to meet up just before they returned to the United States, but Cravan never showed, nor was he ever seen again. Loy searched for him, and later he was assumed dead. Loy was already pregnant with Fabienne, and posthumous can mean ‘born after the death of the father.’ Better yet, a parvenu is one who is unaccustomed to wealth or power, but has recently gained a position of such but hasn’t gained the prestige that comes with the station. Fabienne, as a newborn, is completely unaware of the fact that she has just joined the human race. The fourth stanza of Loy’s poem, â€Å"Delirious Avenues/ lit/ with the chandelier souls/ of infusoria/ from Pharaoh’s tombstones† is a description of Loy’s search for her missing husband. The chandelier reference is also key because shortly after â€Å"Lunar Baedeker† is published, Loy opens a lamp shop and designs the lamps and fixtures herself. At the time that the poem was written, she was probably already dabbling in the art. The â€Å"Delirious Avenues† is a reference to her constantly searching blindly, with no clues, in every place or pathway her husband could be. The people who are a part of Cravan, Fabienne and Mina herself brighten the avenues; they are the â€Å"chandelier souls,† branches, pieces of Cravan. The â€Å"Pharaoh’s tombstone† indicates that Loy finally coming to terms with the fact that her husband is most likely dead. The acceptance of the loss of Cravan comes in the next stanza: â€Å"lead/ to mercurial doomsdays/ Odious oasis/ in furrowed phosphorous† â€Å"Lead† can be interpreted in more than one-way. It can indicate that Loy was brought to a conclusion by the previous stanza, but it can also be defined as the first punch in a boxing match. This is important because Cravan was known as the â€Å"boxer poet† because he was really only a second rate poet and used prize fighting to supplement his income. â€Å"Mercurial† is a reference to Mercury, who is the Greek god of travel, cunning, and theft, and is also associated with swiftness. Mercury is also the second reference in the poem to a shiny, silver colored element; in this case it is a poisonous element. In keeping with Loy’s celestial theme, Mercury is also the closest planet to the sun. Therefore, this doomsday, the loss of her husband, came swiftly, is like poison to her heart, and the heat of the planet Mercury can be paralleled to the fire of Hell. The term â€Å"Odious oasis† is an oxymoron. Loy’s only relief in submitting to the fact that her husband would never return to her was that she could give up searching for him. Her oasis is â€Å"in furrowed phosphorous† because she feels the loneliest at night, the term phosphorous, meaning something that glows or shines, is referring to the stars in the sky. The next stanza is somewhat cryptic, though the many references to white and light and the moon, â€Å"the eye-white sky-light/ white light district,† made me think of virginity and purity. The final line, â€Å"of lunar lusts,† indicates the sexual needs or desires of one who is chaste, another oxymoron. It is most likely Loy voicing her loneliness. At this point in the poem, Loy’s blending of words happens more and more. The first line is â€Å"—Stellectric signs,† —Stellectric being the combination of constellation and electric, meaning that Loy is taking meaning from the constellations in the night sky. The first sign she sees is â€Å"‘wing shows on Starway'† If looked at from a point of view where this is an actual show, as in a theatrical presentation, a wing can be defined as a dance step, and the Starway can be the stage, something similar to Broadway. Loy’s next sign is the â€Å"‘Zodiac carrousel'† which is the cycle of astrological signs that are represented by the constellations in the night sky. A carrousel is a  children’s amusement ride where one would sit on an animal-shape, which would tie in to the zodiac. A carrousel can also mean a cycle of activity that is complex and fast-paced and difficult to break free from. This shows that Loy was in a cycle that she may have been unhappy with. Both the zodiac and the carrousel are the first two of many references to things that are cyclical, or go in circles, or are round even. The next two references to cyclical occurrences are in the next stanza. â€Å"Cyclones† are high-powered storms with low pressure at the center, 99% of which in the northern hemisphere spin in a counterclockwise motion. The fact that they run counterclockwise could be Loy’s rebellion against the cycles she is trapped in, or her feeling that she is stuck in a backward cycle, or a backward life. These cyclones consist â€Å"of ecstatic dust/ and ash† means that Loy’s grief for the loss of her husband is beyond her reason and self-control. The dust represents what something disintegrates into when it is reduced to its lowest form, and can also mean a state of humiliation. The ash, which is the carbon left after something is burned completely, is symbolic of Loy’s grief, repentance and humility. An ash is also a type of tree that has a tough, elastic wood, which represents Loy’s strength and malleability, indicating that she will heal from this l oss. The dust and ashes â€Å"whirl† in this cyclone, another indicator of a circular, cyclical pattern. The next part of the stanza refers to â€Å"crusaders/ from the hallucinatory citadels/ of shattered glass/ into evacuate craters† The hallucinatory citadels is the safety and security Loy thought she had with Cravan. The shattered glass represents Loy’s broken dreams about her ruined marriage and the evacuate craters, which are probably on the moon, are the emptiness into which her broken dreams are siphoned. Crater is another important hint to Loy’s personal life also. Loy was a painter and an artist and a crater can also be a dimple in a painted surface, meaning that there were visible flaws in Loy’s life. Though Loy’s dreams concerning Cravan are broken and gone, she still had goals and aspirations, in fact, she has â€Å"A flock of dreams† still. Those dreams do sometimes â€Å"browse on Necropolis† which means she often thinks of and dreams about her lost husband, Necropolis being the city of the dead. The next stanza is a return to Loy’s lunar theme, and also a reference to a used and tarnished womanhood. â€Å"From the shores/ of oval oceans† The word oval means elliptical and egg shaped, which the orbits of the planets and moons are, but also it is derived from the Latin word ovum, which our word for the female sex cell. The â€Å"oxidized Orient† is the phrase that truly represents a tarnished womanhood. Oxidation is when something has been exposed to oxygen, which has cause a corrosion that is often black, brown or green. Orient is another reference to the moon, which in turn represents chastity. Orient can mean the East, where the sun and moon rise from, or rising in the sky, and also the luster of a pearl. The next image that Loy presents us with is the loss of her thirst for life. In â€Å"Onyx-eyed Odalisques/ and ornithologists/ observe the flight/ of Eros obsolete† dark eyed concubines and studiers of birds watch, inspect, and celebrate as Loy’s no longer useful lust, as Eros is the Greek god of erotic love, and her life-preserving instinct, which is also represented in Eros, leave her. The next stanza where Loy refers to her â€Å"‘Immortality'† as it â€Å"mildews/ in the museums of the moon† Immortality could refer not only to her unending love for Cravan, but also the possibility of her being famous for her writing or her art. The fact that it can mildew means that there truly is no such thing as immortality, but if there was, it would be in a place where it would be looked at and not used: a museum. This museum would be in the moon because the moon represents an unreachable place or goal. The next two lines are direct references to the moon. The â€Å"‘Nocturnal cyclops'† would be the one-eyed being that is active only at night. With the â€Å"‘Crystal concubine'† crystal represents something transparent and pretty, while concubine represents an unmarried woman who lives with a man, which is symbolic of the moon’s relationship with the sun. The very last stanza of â€Å"Lunar Baedeker† is full of meaning. It refers to the moon as â€Å"Pocked with personification† One general thinks that pocked means  to have craters or indents, when in reality it means to have pustules that are filled with infection. By being â€Å"Pocked with personification† the moon is infected with human attributes. The moon is also considered â€Å"the fossil virgin of the skies† Fossil here refers to the fact that the moons representation of purity and chastity are outdated and a remnant of the past. This is also another allusion to astrology in that the virgin, or Virgo, is a sign of the Zodiac. The final three words of this poem are very powerful. When thoroughly considered they represent an inner struggle and inner turmoil. To wax is to increase, grow or intensify, but it can also mean rage. Wane, on the other hand, means to decrease in size and diminish, but it can also be used to describe a loss of power or a fall from power. â€Å"waxes and wanes—-† This is symbolic of Loy’s struggle with her anger and pain after the loss of her husband, and in waning, she relents to her feelings.
