Humanistic Perspective and Addiction Essay - 1420 Words

Tia Gardner September 21, 2012 Humanistic Perspective and Addiction There are several theories of addiction. All of them are imperfect. All are partial explanations. It is for this reason that it is important to be aware of and question addiction theories. One contemporary psychoanalytical view of substance abuse is that it is a defense against anxiety (Thombs D 2006). Addicts often abuse alcohol and other substances to guard against anxiety and other painful feelings like shame, guilt, loneliness and depression. Psychological problems including substance abuse disorders are viewed as a result of inhibited ability to make authentic, meaningful, and self directed choices about how to live. The†¦show more content†¦Is there some genetic difference that perhaps allows some to realize when an elevated blood alcohol level has been reached and transmits a message to the brain to stop drinking that others do not have? These questions have not been clearly answered and are under persistent investigation. Among the numerous definitions for addiction, there lies yet another to define it from a biochemical perspective. Milkman (1983) defines it as â€Å"self-induced changes in neurotransmission that result in social problem behaviors. This definition encompasses the psychological, biochemical and social aspects of addictive processes. It is not limited to substance abuse and can be applied to any activity characterized by compulsion, loss of control and continuation of the substance despite harm. This has helped investigators gain a better understanding of the nature of addiction. It has been shown that individuals turn to drugs that elicit a mood or level of arousal consistent with their mode of dealing with stress. Those who deal with stress by confrontation choose drug stimulants. Those who withdrawal from stress chooses opiate drugs. Others who deal with stress through activities related to imagery or fantasy turn to hallucinogens. These differences between behavior and drug preference are thought to be biochemically driven.

Low Levels Of Academic Achievement - 955 Words

lower levels of academic achievement and it is also known that Latino adolescents experience great levels of depression symptoms constantly†( ). According to the National Center for Education Statistics (2007), nearly 63% of Latino Adolescents in the United States achieve a high school degree, as opposed to 87% of African American Adolescents. Latino youth similarity report experiencing elevated levels of depression symptoms than the children from other groups. Research shows that academic achievement and depression are negatively associated to each other, however there is lack of evidence that results in an inconclusive understanding of this relationship. This negative relationship is seen for a variety of academic measures, which include the standardized achievement test, grades, and teachers ratings, yet the direction of causality in this relationship is still unknown AND Modern research, today in this association is lacking. Previous studies have found groundwork to the presented issue. In a meta-analysis of Children’s Depression Inventory (CDI), Twenge and Nolene-Hoelcsema (2002) found that Latino children and adolescents endorsed considerably higher depressive symptoms, obtaining higher scores on the CDI than children from other ethnic groups.

A Dose of Fear Free Essays

Once on a dark, stormy autumn’s evening, the grey fog hung so thick and heavy over the country lane that it blocked the view of the landscape. The gloomy, cumulonimbus clouds filled the thick, filthy air that smelt of dirty sewage water, as if there had been flames of fire that had let off a lot of smoke. You could hardly see a thing unless you had perfect vision. We will write a custom essay sample on A Dose of Fear or any similar topic only for you Order Now In the evening nearby an inconspicuously, deserted mansion that was about fifty metres away from the narrow, odd, tarmac road in the countryside, branches creaked and birds squeaked in their nests. It seemed to him like many days since he had begun to prepare his mind for â€Å"the camp† as he always called it. Seth Winston was a fifteen-year-old adventurous teenager who was so alive, vital and positive about everything. He also had a personality that one could not ignore. He had dark, brown eyes, short black hair and olive skin. His mother had died when he was born so he had never known or missed her. However, his young and handsome father seemed to be the only relation he had in the world apart from Ruth and Peter his caring and loving best friends. Ruth Mathews was sixteen years old, had blue eyes and ginger hair. There was more connection between her and Seth. On the other hand, Peter St John was an eighteen year old; who only had one thing in common with Seth and that was camping. That Saturday afternoon at half past two, Seth, Ruth and Peter set off to go camping in the countryside. This would have been their first camp ever without Seth’s father because Peter was old enough to drive and owned a driving licence. â€Å"This is going to be the best camp ever,† said Seth in an excited voice as Peter started to drive. Three hours later nearly two hundred miles away from town, the weather began to change from slightly warm and sunny to heavy rainfall. As darkness drew closer, the rain got worse every minute and the country lane became too slippery to drive the car. â€Å"I think you need to stop at the side of the road until the weather gets better Peter,† said Ruth in a tentative voice. â€Å"Don’t be silly, we’ve only got a few more miles to go until we reach the camping site,† said Peter in a voice that was struggling to hide the fear inside him. â€Å"Guys I think I see something,† Seth said loudly wishing it was a place to escape the unexpected heavy rain. â€Å"What is it?† Ruth and Peter both spoke at the same time desperate to find out what it was. â€Å"It looks like a house. A mansion.† Seth answered in an uncertain tone. â€Å"Let’s go and check it out,† Ruth suggested positively as if she knew exactly what it was. Peter made a left turn and slowly drove down in the open space towards the secluded, big mansion. When they reached the faded, rusty gate, they stepped out of the car and put their coats on. It was open so it made it easier for them to get to the mansion. In approaching the mansion, there was a chill in the air as they hurriedly walked to the door. Ruth knocked on one of the huge oak doors although they were slightly open. She knocked five times and waited but there was no response. â€Å"Hello, is anybody here?† Ruth shouted as she echoed repeatedly and as water dripped from her round face. â€Å"Did you hear that? Someone just repeated what Ruth just said,† Seth said sarcastically. â€Å"Are you stupid? That was her echo, you fool,† Peter said in a rather unimpressed high pitch voice. Helplessly desperate for shelter, they decided to step inside. The view captured their eyes. Joined cobwebs smeared the walls and an unidentified smell of rot filled their nostrils. The dusty, mouldy ceilings dripped with water. Peter seemed to be more fascinated by the unusual scene than the other two, so without them noticing, he decided to take a tour around. The door creaked behind Peter as he escaped into the next room. With their heads held up high, Seth and Ruth looked to see where the sudden noise had come from. Just as they turned round, they were horrified by a dead bat, which had fallen two metres above their heads from the spider web that hung under the ceiling. They heard a loud scream coming from the next room on their left that sounded as if someone was being tortured. They fled into that treacherous room as fast as they could. On its walls were skulls portrayed in a devilish appearance splashed with rotten blood. When they looked down, they saw a half naked body viciously assaulted dripping with blood on the black tiled floor. The floor was littered with bones and headless skeletons that were gathered through the courts of time. Satanic crosses were marked all over the ceiling and the atmosphere was heinous. Seth and Ruth could not believe the monstrous view in front of their eyes. Horrendous injuries covered the body and the eyes had popped right out of the skull. They were wide open, stony with the glassiness of death. Only one nostril was left of the nose and was dripping with mucus and blood. The lips were deformed. With a grimace of his face, Seth wondered what kind of a vicious, menacing sinister who would do such a terrible act. The slimy small and large intestines were noticeable and cut open that they dared not to look at the brutal stomach, which looked as if it had had an abdominal surgery. â€Å"I’m so sorry Peter,† said Ruth in a petrified voice trying her hardest not to burst out in tears. â€Å"Who could do such damage to an innocent soul?† Seth questioned silently as tear drops fell from his eyes. Seth noticed a sombre shadow with an axe in its hand on the wall at his right hand side. At first, he did not say anything because he was not sure where it was coming from. â€Å"Ruth look out!† shouted Seth. â€Å"Where?† Ruth shouted back. â€Å"Behind you!† Seth answered in a despairing voice. Ruth looked behind her, widened her blue eyes in terrified horror while her jaw nearly dropped on the ground and screamed, â€Å"No!† At this moment, Seth had nothing else to say or do but save himself. He ran out of the room as fast as he could and raced to the other side of the mansion as if chased by hideous demons. This end had autumn leaves on the floor that two open triangular windows had let in. He fled into the nearest room that he believed was safe as he had the intension to hide. Although it was not as bad as the previous one, this room was damp and infested but with a gnaw feeling, Seth did not take any notice. There was a rustling noise; it grew louder and more persistent. When it started, Seth had thought that leaves were blowing in the sweeping wind but now it was far too loud for that. It sounded like someone stomping through crisp packets. The rustling turned to crunching, as if some huge animal was munching on a giant creamcraker. Seth shivered. He pulled his coat tightly around him because he was cold. He clenched his fists in his pockets. He stared at the floor in front of him and occasionally glanced nervously at the door handle. â€Å"You must keep calm,† Seth repeatedly said to his self as he breathed heavily as if he was starving from oxygen. Seth desperately looked at the impenetrable window wishing he were small enough to fit through so he could escape the haunting poltergeist. In the darkness of the fading light, the poltergeist’s face had the pallor and sheen not so much of flesh so much of bone itself. Seth stared at it until his eyes ached in their sockets in surprise and bewilderment at its presence. With the combination of the peculiar, isolated room, the appearance of the poltergeist and the dreadfulness of its expression began to fill Seth with anxiety. Indeed Seth, never in his life was so threatened by anything like that. He had never known his heart to give such a great lurch, as if it would almost leap out into his shivering, dry mouth and then begin pounding in his chest like a hammer hitting an anvil. Seth never thought that a dose of fear would make his knees tremble and his flesh creep. He never imagined himself daunted and held fast by such dread, horror and apprehension of evil. His worst nightmares had resurrected. How to cite A Dose of Fear, Papers

We know how to meet once a year or every two years. Therefore, we have to talk by phone. First, I usually ask some questions about my homework when I call him. But gradually we are able to talk about our personal things after a while. For example, our recollection stories, lip talks and so on. I am capable of doing this because to accept my brother and we live apart each other. I thought the long distance can shorten our mind gaps of unimportant things. Recently, we met each other in this pass summer. One day, my brother and I went to watch a movie at night. We talked about love stories first time and normally on the way to theater. We arrived at theater, my brother bought tickets, popcorn and coke for me. I felt happy like it had always been so. After watching the movie, I felt so happy and I fascinate asked, â€Å"Hey! How many girlfriends did you get?† My brother asked me with shy, â€Å"I don’t know! I can’t count about it!† I said, â€Å"Just kidding! Ok, I will change the question!! What is shocking comment from your girlfriends?† my brother told me so easy, â€Å"Your feeling is too deep for me!!!!† I agree. We talked about story of it, my brother’s love stories again and story in the future on the way to home. When we arrived at home, my mother, father and grandmother greeted, â€Å"Okaeri (Welcome home).† We replied, â€Å"We are home, the movie is good!!† The next day, my brother helped my homework. After finishing it, we went to a Shopping Mall. He chose my clothes for me. My brother treated me normally, so I realized that my brother is a good person. The whole reason for my dislike of my brother disappeared with time and distance. We had a big fight over a stupid electric cord and for that we lost our friendship time in our home together. Then we were separated from each other. Now I know that the chance with my brother is important and we must treasure like that.

Wireless Elecricity Essay Example

Wireless Elecricity Essay Niharika Sharma Applied Electronics and Instrumentation Engineering, [emailprotected] com Varun Pachauri Electronics and Communication Engineering, [emailprotected] com Wireless Electricity Abstract—The present paper intends to link several disciplines in an attempt to describe the concept of wireless electricity. Wireless transmission is useful in cases where interconnecting wires are inconvenient, unaffordable, expensive, hazardous, unwanted or impossible. A large part of the energy sent out by the generating plant must arrive at the receiver to make the system economical.Some common forms of wireless electricity transmission methods are Direct Induction followed by resonant magnetic induction, electromagnetic radiation  in the form of  microwaves  or  lasers. With this technology we can reduce power losses produced through wired lines. Different concepts and application of wireless power transmission are discussed in this paper. Introduction The definition of Wirele ss Power Transmission is: efficient transmission of electric power from one place to another through vacuum or an atmosphere without the use of wire or any other substance.Maxwells theory of electromagnetism, published in 1865 mentions electromagnetic waves moving at the speed of light, and the conclusion that light itself was just a wave. In 1886 H. Hertz performed an experiment with pulsed wireless energy transfer. . He produced an apparatus that generated and detected microwaves in the UHF region. Tesla also performed experiments in the field of pulsed wireless energy transfer in 1899. Teslas Magnifying Transmitter, an early type of Tesla Coil that measured 16 meters in diameter, could able to transmit tens of thousands of watts without wires.In present electricity generation system we waste more than half of its resources. The transmission of power without wires may be one idle alternative for electricity. Future suitable and largest application of the WPT via microwave is a Spa ce Solar Power Satellite. History of Wireless Electricity In 1864, James Maxwell predicted the existence of radio waves by means of mathematical model. In 1884, John Poynting realized that the Poynting Vector would play an important role in quantifying the electromagnetic energy.In 1888, bolstered by Maxwells theory, Heinrich Hertz first succeeded in showing experimental prove of radio waves by his spark-gap radio transmitter. The prediction and prove of the radio wave in the end of 19th century was start of the wireless power. The Raytheon Company performed the first successful WPT experiment in 1963. In this experiment power was transmitted with a DC-to-DC efficiency of 13%. The Raytheon Company also demonstrated a microwave-powered helicopter in 1964. In 1975, Jet propulsion lab of NASA carried out an experiment and demonstrated the transfer of 30 kW over a distance of 1 mile.This test demonstrated the possibilities of wireless energy outside the laboratory. Rockwell Internationa l and David Sarnoff Laboratory operated in 1991 a microwave powered rover at 5. 87 GHz. Three kilowatts of energy was transmitted and 500 watts was received. In 1980s, Japanese scientists developed the MPT technologies and research. In 1983 and 1993, Matsumoto’s team carried out the first Microwave Power Transmission experiment in space. The rocket experiment was called Microwave Ionosphere Nonlinear Interaction experiment i. . MINIX in 1983 (Fig. 1) and International Space Year – Microwave Energy Transmission in Space in 1993, respectively. They focused nonlinear interaction in between intense microwave and plasmas. In this experiment, they used cooker-type 800W-2. 47GHz magnetron for microwave transmitter. New wave-wave-particle interaction phenomenon was observed in this experiment. Plasma theory and computer experiments also supported the observations. Figure 1. MINIX Rocket experiment in 1983 Technologies for Wireless ElectricityThe modern ideas are dominated by m icrowave power transmission called Solar power satellite to be built in high earth orbit to collect sunlight and convert that power into microwaves, then beamed to a very large antenna on earth, the microwaves would be converted into conventional electrical energy. A microwave transmission system consists of three essential parts: ? Electrical energy to microwave energy conversion ? Absorption antenna that collects the waves ? (Re)conversion to electrical energy Figure 2. Microwave transmitter and rectennaThe microwave source consists of a microwave oven magnetron with electronics to control the output energy. The output microwave energy ranges from 50 W to 200 W at 2. 45 GHz. A coaxial cable connects the output of the microwave source to coax-to-waveguide adapter. This adapter is connected to a waveguide ferrite circulator which protects the microwave source from reflected energy. The circulator is connected to a tuning waveguide to match the waveguide impedance to the antenna inpu t impedance. The slotted waveguide antenna consists of 8 wave guide sections with 8 slots per section.These 64 slots radiate the energy uniformly through free space to the rectenna. The slotted waveguide antenna is ideal for energy of its high aperture efficiency (;gt;95%) and high power handling capability. A rectifying antenna called a rectenna receives the transmitted energy and converts the microwave power to direct current (DC) power. This rectenna consists of 6 rows of dipoles antennas where 8 dipoles belong to each row. Every row is connected to a rectifying circuit which consists of low pass filters and a rectifier. The rectifier is a Ga As Schottky barrier diode i. . impedance matched to the dipoles by a low pass filter. The 6 rectifying diodes are connected to light bulbs for indicating that the energy is received. The light bulbs also dissipated the received energy. This rectenna has a 25% collection and conversion efficiency, but rectennas have been tested with more than 90% efficiency at 2. 45 GHz. Another possibility is to use highly efficient fibre lasers for wireless energy transmission where the possibilities are similar to microwaves concept but lasers emit energy at frequencies much higher than microwave.For several years NASA, ENTECH, and UAH have been working on various aspects of collection of the laser radiation and conversion to electrical energy for laser wireless energy transmission. Figure 3. Two optical forms of wireless antenna formed of search light beam-ionised atmospheric stream Applications of Wireless Electricity Wireless Power for Space Solar Satellites * The largest application for microwave power transmission is Space Solar Power satellites. In this application, solar energy is captured in space and converted into electricity.The electricity is converted into microwaves and transmitted to the earth. The microwave energy will be captured with antennas and converted into electricity. NASA is still investigating the possibilit ies of solar power satellites. Main problem is the high investment cost due to the space transport. The current rates on the Space Shuttle run between $7,000 and $11,000 per kg of transported material. * Table. 1-Parameters for transmiting antenna for sps system * Figure. 4. Space Solar Power Satellite Power Supply for Rural AreasWireless power can be an option for power supply to rural areas. In 1993, a project presented about wireless power supply in Alaska. Because of limited infrastructure, numbers of small rural communities in Alaska must provide their own electricity. These systems can be expensive or just not available. At the moment, the small communities produce their own power with mostly diesel engines. These produce so noise and pollution. Also the required fuel has to be transported over long distances. This results in an electricity price in excess of $40/kWh.In Alaska cable connections through water is no alternative because of ice. With the help of WPT, the required power production of the communities can be combined. It can reduce noise, pollution and transportation of fuel. WPT may be capable of transmitting electrical power to Alaska’s remote villages. To investigate these possibilities, a project was conducted named Alaska21†. System used for the project consisted of a 2. 46 GHz phased array design. The distances should be bridged are between 1 and 15 miles. Figure. 5. Alaska’21 * V.Merits of Wireless Electricity An electrical distribution system, based on this method would eliminate the need for the costly and capital intensive grid of cables, towers, and substations. The system would also reduce the cost of electrical energy used by the consumer and rid the landscape of wires, cables, and transmission towers. There are areas of the world where the need for electrical energy exists, yet there is no method for delivering energy. Africa is in need of energy to run pumps to tap into the vast resources of water under the Sa hara Desert.Rural areas, such as those in China, require the electrical energy necessary to bring them into the 20th century and to equal standing with western nations. The wireless transmission will solve most of above problems. The electrical power can be economically transmitted without wires to any terrestrial distance, so there will be no transmission and distribution loss. Figure 6. An office using wireless electricity Demerits of Wireless Electricity A common criticism of the wireless power system is regarding its possible biological effects.Calculating the circulating reactive power, it was found that the frequency is small and such a frequency is very biologically compatible. A general perception that microwaves are harmful has been a major obstacle for the acceptance of power transmission with microwaves. One major concern is that the long-term exposure to low levels of microwaves might be unsafe and even could cause cancer. Conclusion The transmission of energy without wi res is not a theory or a mere possibility, it is now a reality. The electrical power can be economically transmitted without wires to any terrestrial distance.Many researchers have established in numerous observations and experiments qualitative and quantitative. It is clear that wireless power transmission systems in the range of 100 W to 100 kW to cannot compete with traditional systems just looking at the costs. At those places where economic competition is not the prime consideration, it can be an option. Microwave wireless energy transmission can supply energy to those places that are difficult to reach. Especially small communities in rural areas could be supplied with power using wireless power transmission.The problems of a possible lack of energy during the next fifty or hundred years could be solved by the Space Solar Power Station. The system would reduce the cost of electrical power used by the consumer and get rid of the landscape of wires, cables, and transmission towe rs.

Wireless transmission is useful in cases where interconnecting wires are inconvenient, unaffordable, expensive, hazardous, unwanted or impossible. A large part of the energy sent out by the generating plant must arrive at the receiver to make the system economical.Some common forms of wireless electricity transmission methods are Direct Induction followed by resonant magnetic induction, electromagnetic radiation  in the form of  microwaves  or  lasers. With this technology we can reduce power losses produced through wired lines. Different concepts and application of wireless power transmission are discussed in this paper. Introduction The definition of Wirele ss Power Transmission is: efficient transmission of electric power from one place to another through vacuum or an atmosphere without the use of wire or any other substance.Maxwells theory of electromagnetism, published in 1865 mentions electromagnetic waves moving at the speed of light, and the conclusion that light itself was just a wave. In 1886 H. Hertz performed an experiment with pulsed wireless energy transfer. . He produced an apparatus that generated and detected microwaves in the UHF region. Tesla also performed experiments in the field of pulsed wireless energy transfer in 1899. Teslas Magnifying Transmitter, an early type of Tesla Coil that measured 16 meters in diameter, could able to transmit tens of thousands of watts without wires.In present electricity generation system we waste more than half of its resources. The transmission of power without wires may be one idle alternative for electricity. Future suitable and largest application of the WPT via microwave is a Spa ce Solar Power Satellite. History of Wireless Electricity In 1864, James Maxwell predicted the existence of radio waves by means of mathematical model. In 1884, John Poynting realized that the Poynting Vector would play an important role in quantifying the electromagnetic energy.In 1888, bolstered by Maxwells theory, Heinrich Hertz first succeeded in showing experimental prove of radio waves by his spark-gap radio transmitter. The prediction and prove of the radio wave in the end of 19th century was start of the wireless power. The Raytheon Company performed the first successful WPT experiment in 1963. In this experiment power was transmitted with a DC-to-DC efficiency of 13%. The Raytheon Company also demonstrated a microwave-powered helicopter in 1964. In 1975, Jet propulsion lab of NASA carried out an experiment and demonstrated the transfer of 30 kW over a distance of 1 mile.This test demonstrated the possibilities of wireless energy outside the laboratory. Rockwell Internationa l and David Sarnoff Laboratory operated in 1991 a microwave powered rover at 5. 87 GHz. Three kilowatts of energy was transmitted and 500 watts was received. In 1980s, Japanese scientists developed the MPT technologies and research. In 1983 and 1993, Matsumoto’s team carried out the first Microwave Power Transmission experiment in space. The rocket experiment was called Microwave Ionosphere Nonlinear Interaction experiment i. . MINIX in 1983 (Fig. 1) and International Space Year – Microwave Energy Transmission in Space in 1993, respectively. They focused nonlinear interaction in between intense microwave and plasmas. In this experiment, they used cooker-type 800W-2. 47GHz magnetron for microwave transmitter. New wave-wave-particle interaction phenomenon was observed in this experiment. Plasma theory and computer experiments also supported the observations. Figure 1. MINIX Rocket experiment in 1983 Technologies for Wireless ElectricityThe modern ideas are dominated by m icrowave power transmission called Solar power satellite to be built in high earth orbit to collect sunlight and convert that power into microwaves, then beamed to a very large antenna on earth, the microwaves would be converted into conventional electrical energy. A microwave transmission system consists of three essential parts: ? Electrical energy to microwave energy conversion ? Absorption antenna that collects the waves ? (Re)conversion to electrical energy Figure 2. Microwave transmitter and rectennaThe microwave source consists of a microwave oven magnetron with electronics to control the output energy. The output microwave energy ranges from 50 W to 200 W at 2. 45 GHz. A coaxial cable connects the output of the microwave source to coax-to-waveguide adapter. This adapter is connected to a waveguide ferrite circulator which protects the microwave source from reflected energy. The circulator is connected to a tuning waveguide to match the waveguide impedance to the antenna inpu t impedance. The slotted waveguide antenna consists of 8 wave guide sections with 8 slots per section.These 64 slots radiate the energy uniformly through free space to the rectenna. The slotted waveguide antenna is ideal for energy of its high aperture efficiency (;gt;95%) and high power handling capability. A rectifying antenna called a rectenna receives the transmitted energy and converts the microwave power to direct current (DC) power. This rectenna consists of 6 rows of dipoles antennas where 8 dipoles belong to each row. Every row is connected to a rectifying circuit which consists of low pass filters and a rectifier. The rectifier is a Ga As Schottky barrier diode i. . impedance matched to the dipoles by a low pass filter. The 6 rectifying diodes are connected to light bulbs for indicating that the energy is received. The light bulbs also dissipated the received energy. This rectenna has a 25% collection and conversion efficiency, but rectennas have been tested with more than 90% efficiency at 2. 45 GHz. Another possibility is to use highly efficient fibre lasers for wireless energy transmission where the possibilities are similar to microwaves concept but lasers emit energy at frequencies much higher than microwave.For several years NASA, ENTECH, and UAH have been working on various aspects of collection of the laser radiation and conversion to electrical energy for laser wireless energy transmission. Figure 3. Two optical forms of wireless antenna formed of search light beam-ionised atmospheric stream Applications of Wireless Electricity Wireless Power for Space Solar Satellites * The largest application for microwave power transmission is Space Solar Power satellites. In this application, solar energy is captured in space and converted into electricity.The electricity is converted into microwaves and transmitted to the earth. The microwave energy will be captured with antennas and converted into electricity. NASA is still investigating the possibilit ies of solar power satellites. Main problem is the high investment cost due to the space transport. The current rates on the Space Shuttle run between $7,000 and $11,000 per kg of transported material. * Table. 1-Parameters for transmiting antenna for sps system * Figure. 4. Space Solar Power Satellite Power Supply for Rural AreasWireless power can be an option for power supply to rural areas. In 1993, a project presented about wireless power supply in Alaska. Because of limited infrastructure, numbers of small rural communities in Alaska must provide their own electricity. These systems can be expensive or just not available. At the moment, the small communities produce their own power with mostly diesel engines. These produce so noise and pollution. Also the required fuel has to be transported over long distances. This results in an electricity price in excess of $40/kWh.In Alaska cable connections through water is no alternative because of ice. With the help of WPT, the required power production of the communities can be combined. It can reduce noise, pollution and transportation of fuel. WPT may be capable of transmitting electrical power to Alaska’s remote villages. To investigate these possibilities, a project was conducted named Alaska21†. System used for the project consisted of a 2. 46 GHz phased array design. The distances should be bridged are between 1 and 15 miles. Figure. 5. Alaska’21 * V.Merits of Wireless Electricity An electrical distribution system, based on this method would eliminate the need for the costly and capital intensive grid of cables, towers, and substations. The system would also reduce the cost of electrical energy used by the consumer and rid the landscape of wires, cables, and transmission towers. There are areas of the world where the need for electrical energy exists, yet there is no method for delivering energy. Africa is in need of energy to run pumps to tap into the vast resources of water under the Sa hara Desert.Rural areas, such as those in China, require the electrical energy necessary to bring them into the 20th century and to equal standing with western nations. The wireless transmission will solve most of above problems. The electrical power can be economically transmitted without wires to any terrestrial distance, so there will be no transmission and distribution loss. Figure 6. An office using wireless electricity Demerits of Wireless Electricity A common criticism of the wireless power system is regarding its possible biological effects.Calculating the circulating reactive power, it was found that the frequency is small and such a frequency is very biologically compatible. A general perception that microwaves are harmful has been a major obstacle for the acceptance of power transmission with microwaves. One major concern is that the long-term exposure to low levels of microwaves might be unsafe and even could cause cancer. Conclusion The transmission of energy without wi res is not a theory or a mere possibility, it is now a reality. The electrical power can be economically transmitted without wires to any terrestrial distance.Many researchers have established in numerous observations and experiments qualitative and quantitative. It is clear that wireless power transmission systems in the range of 100 W to 100 kW to cannot compete with traditional systems just looking at the costs. At those places where economic competition is not the prime consideration, it can be an option. Microwave wireless energy transmission can supply energy to those places that are difficult to reach. Especially small communities in rural areas could be supplied with power using wireless power transmission.The problems of a possible lack of energy during the next fifty or hundred years could be solved by the Space Solar Power Station. The system would reduce the cost of electrical power used by the consumer and get rid of the landscape of wires, cables, and transmission towe rs. It has negligible drawbacks like reactive power which was found insignificant and biologically compatible. References James O.

Christopher Columbus Essay Essays

Christopher Columbus Essay Essays Christopher Columbus Essay Essay Christopher Columbus Essay Essay Essay Topic: Clueless The Outsiders Essay on Christopher Columbus: The discovery of America In the modern day US, Christopher Columbus is celebrated as the man who discovered America. As controversial as the context of the word discovered may be used in, the first Monday of every October is the day Americans take their time to celebrate the heroics of Columbus sailing through the Atlantic Ocean to discover the new land in the October of 1492. As an experienced explorer, Columbus had been commissioned by the Spanish Monarch government to explore the rough waters and find the location of China or Japan for trade purposes. However, Columbus ended up on a series of islands that he collectively named as the East Indies, each island with a specific name dedicated to the upper ruling class of Spain. It was later discovered that they were not East Indies but rather a new land that the Spanish Empire claimed territory to. The sailing of Columbus towards the present day America explains how colonization and settlement of more European people at the territory was conceived. Therefore, in studying the explorative trip that was undertaken by Columbus to find Japan only to find the new land, one gains a better insight on the concept of colonization and how the historical injustices towards the natives began. In achieving its objective, this analysis uses both primary and secondary sources to understand the objective of Columbus and its aftermath. Columbus First Voyage to America Collectively, historical analysts point out that Columbus made four voyages across the Atlantic Ocean to the present day South and North America. Although each voyage was significant to the territory expansion of the Spanish, much emphasis is put on the success of the first one. Before Columbus came to be recognized as a great hero, Spain had just unified into one with the monarch government being headed by Queen Isabella of Castile and King Ferdinand of Aragon. The two were responsible for the age of exploration for the Spanish Empire and through their leadership; Columbus was accorded the much-needed support to make the exploration. As he wrote in the letter, it only took Columbus and his team of conquistadors to arrive at the islands that form the present-day Bahamas, Cuba, Haiti and the Dominican Republic. This was in the October of 1492. On the islands, there were natives who living a totally different lifestyle and lacked all significant elements that European people deemed to be significant. For instance, they neither had towns or cities nor did they have functional governments. As described by Columbus in the letter he wrote back to the King and Queen; the natives were more affectionate to the outsiders regardless of the fact that they also feared the Europeans. Their innocence portrayed them as nave, an aspect that Columbus and other warrior explorers decided to take advantage of. After close to eight months, Columbus arrived back in Spain in March 1493. As Gallagher notes, great celebrations were made in the name of the new hero, Columbus. Several historical accounts analyzed by historians do not deviate from the primary information that was handcrafted by Columbus. In the account presented by the Saylor Foundation, it is evident that the exploration trips were taken seriously by the monarch government. The conquistadors who accompanied Columbus during all the four voyages were not just mere men but trained warriors. Their versatility and ability to endure harsh environments is what made the exploration a success. In the study by Stannard, demographers estimated the total population of inhabitants in the New World, which is the present day north of Mexico to be 12 million people. All that was about to change with the arrival of Columbus and his discovery of their territory as a New World, initially East Indies. Historical significance of Christopher Columbus America, as it is today, is a place that many people aspire to visit. It is the perfect place where true happiness and good life experiences occur as per the depictions of Hollywood. Clueless to all such people is that all that glitters is not gold. Amidst the happy place that is the current America, the country possesses a gloomy past dominated by historical injustices perpetrated to the minority. All these can be traced back to one celebrated event; the discovery of America by Columbus. Although historical accounts signal that Columbus was not the first European or foreigner to step foot on what he determined as the new world, it was his arrival that acted as the onset of injustices against the natives. Upon the success of the first voyage, to which Columbus claimed Spanish territory of five islands that were already inhabited, three subsequent voyages were organized by the monarch government. The agenda of the voyages that followed upon the first success was to carry more warriors who could secure and establish the authority of the Spanish Empire on the newly claimed territories. From a historical perspective, it was the beginning of colonization. More European settlers, from other countries, also saw an opportunity to grab a New World that was deemed free for grabs. While all these was going on, it is important to note that the natives, who had inhabited the land for more than 30,000 years were still living there. Controversies associated with the whole issue emanate from the term discover. How can a land that people are already living on be discovered? In the three historical accounts that have been used to cover this paper, it is evident that the arrival of European settlers led to the demise of the native communities. Historical sources point out that almost 90% of the original native communities were wiped out during the era that European settlers were grabbing America. One of the reasons that may have led to the killing of the natives by the teams led by Columbus was their refusal to uphold Christianity. As covered by Stannard and Gallagher, the monarch government had declared to enforce Christianity while eradicating other forms of religion. As such, rebellious people were killed or exiled. The natives that Columbus arrived back with after the first voyage were all converted to Christianity. In general, the suffering of natives began from the time that Columbus claimed to have discovered a new world. In summary, it is significant to acknowledge and appreciate the success of Columbus first voyage to the New World as the conception of the present-day America. Natives still live in reservations camps on a land that was theirs in the first place. Such incidences can be traced to the voyages of Columbus quest, which was originally set to locate China or Japan for economic reasons. As a discovery that happened by mistake, Columbus success marked the beginning of European settlers in the Americas. The Letter of Columbus in the Discovery of America.

Socio-technical leading to IT failure in Terminal 5 Essay

Socio-technical leading to IT failure in Terminal 5 - Essay Example Before merger of these two characteristics, socio and technical, the strategic planning for developing information systems was poor. The information systems were developed according to technological needs and the experts had formed systems on technical framework (Flichy, 2003). In this world of competitions, the organizations need perfection and reasons to be major contestant in the relevant field. Choppy and Sokolsky (2008) express that the efficiency, quality of services QoS, work load, accuracy and management are possible only by the help of socio-technical involvement. For the achievement of strategy of planning and development, the organizations implement and evaluate the state-of-the-art technologies with the flair of socio-technical system. On the other hand, as Godinez et al (2010) articulate, the dependency on technologies and hiring untrained staff are the factors which create lots of hindrances. And socio-technical system has also the limitations, so that the possibilities of design of faulty systems still persist in the world. Today, the concept of data management is incomplete, almost impossible, without information management systems. Information systems supply a complete and wide-range of solutions for organizations, either public or private. Curtis and Cobham (2008) express that the information system applications, based on software and hardware, are developed for different purposes and for different organisations. Airports, railway stations, hospitals, universities, accounts and audit bureaus and almost all the public organizations use these applications for ease in management. Information systems also help in decision making and timely completion of projects (Ulrich and Newcomb, 2010). In this paper, the relationship between information systems and socio-technical system is widely discussed. Moreover, the
