Black Plague Essays (3039 words) - HIVAIDS, Duesberg Hypothesis

Black Plague As a young adult I must endure many scary realities of this world. Everyday a new challenge, obstacle, fear stares me right in the eye. The sugarcoated, innocent, ?never ?never? land is quickly shedding from my reality and I am faced with the truths of this cynical world. Truth. Do I know the meaning of this word? What if all I have trusted had been false, what if those endless nights I lied awake worried over the latest medical news, or any news for that matter, was all just a waste of potentially productive time? What if the world as we know it was all just a hoax and a set up to make the men in the white coats rich? According to Dr. Peter Duesberg, HIV as we know it is not the cause of AIDS or death, but rather the habitual use of hard drugs and or the treatments used for HIV, AZT a very harsh medication first developed for the treatment of cancer, that is causing the immune deficiency. Before I even understood completely what sexual intercourse or intravenous drug-use was, I was told what HIV was. The ?black plague? of the 80's and 90's, killing off people by the thousands spread by unprotected sex and dirty needles. But what if this scare was purposely inflicted as an experiment on the American people or what if was all just a human error. Dr. Peter Duesberg is a professor of molecular and cell biology at the University of California, Berkeley. He has pioneered the studies in the phenomenon that HIV is not the cause of AIDS. Dr. Duesberg is the first to isolate the cancer gene through his work on retroviruses and mapped the genetic structure of these viruses. He is an outstanding investigator recognized by the National Institutes of Health, making him more than creditable for his claim. Dr. Duesberg has challenged the virus-AIDS hypothesis claiming that the public has been misinformed. The believers in this claim feel that HIV was invented for an explanation for AIDS, and equally the treatments used were even causing the AIDS illness. Let's begin by defining HIV/AIDS according to the World Health Organization (WHO), modern science and medicine and what is being taught in classrooms and clinics all over the world. HIV stands for Human Immunodeficiency Virus and like any other virus can only replicate inside cells. In short, it attacks the ?T-cells? which make up our immune system. In the final course of the virus the infected person ?becomes particularly vulnerable to the opportunistic infections and cancers that typify AIDS?(pg. 1 www.charweb.com). HIV is shown to be the cause of AIDS. AIDS stands for auto immune deficiency syndrome and is defined by a severe depletion of t-cells and over 20 controversial degenerative and neoplastic diseases, and is 100% fatal. But believers in the phenomenon claim that this information is misleading and incorrect. Dr. Duesberg has proposed the hypothesis that the various AIDS diseases are brought on by the long term consumption of recreational drugs and AZT, which is prescribed to prevent or treat AIDS. In the studies and research conducted the in the correlation between HIV and AIDS many cases of AIDS show no sign of HIV. ?In the United States and Europe AIDS correlates to 95% with risk factors, such as about 8 years of promiscuous male homosexuality, intravenous drug use, or hemophilia. Since AIDS also correlates with antibody to a retrovirus, confirmed in about 40% of American cases, it has been hypothesized that this virus causes AIDS by killing T-cells. Consequently, the virus was termed human immunodefieciency (HIV) and antibody to HIV became part in the definition of AIDS.?(pg1www.duesberg.com) In other words scientist pinned HIV on this virus because HIV kills t-cells and AIDS kills T-cells so they must be one in the same? When we exam the hypothesis that HIV causes AIDS we must look at classical conditions for viral pathology, in which HIV violates. A virus replicates inside cells very rapidly and the body fights the virus through the immune system. Supposedly HIV infects the T-cells and kills them, but about 5% of all T-cells are regenerated during the 2 days that it takes the virus to infect

Free Essays on The Inspiration And Demise Of Revolutionary Leaders Free Essays on The Inspiration And Demise Of Revolutionary Leaders The Inspiration and Demise of Revolutionary Leaders Huey P. Newton and Tupac Shakur were two revolutionary soldiers from two different time periods and two different social environments. Huey was one of the founders of the Black Panther Party and Tupac, a rapper who strived to make young blacks aware of the war that they inflicted upon themselves as a result of oppression. Though from different time periods, they both exerted the same dedication to a similar movement that represented their people. â€Å"By having no family, I inherited the family of humanity† (Newton 162). Both men lived by the â€Å"I am we† (Newton, 180) concept. They believed that every man is a representative of his own people and to start a revolution in the individual is to start a revolution of a people. For this reason Huey believed that each individual person should look within himself or herself to make a change and not to a leader. Tupac’s music delivered a similar message. In an interview Tupac mentioned that black people have asked for equality for too long, â€Å"Now what do you think were going to do? Ask?† (Shakur 16). With his powerful words he encouraged his listeners not to take oppression quietly and to challenge the hegemonic power of our society. Both Tupac and Huey strived to leave revolutionary legacies.

LTC Administrators and Alzheimers's Disease Essay

LTC Administrators and Alzheimers's Disease - Essay Example According to the Alzheimer’s Association of America, 5.3 million Americans have this disease in 2015 (Alzheimer’s Association of America, 2015). The ages for the affected individuals varies as 5.1 million of them are above the age of 65 while 200,000 are under the age of 65. The Association also states that two-thirds of the affected are women. The figures state that from the 5.3 million affected individuals 3.2 million are women while 1.9 are men. In addition, the number of patients is expected to grow each year as the proportion of Americans who are above the ages of 65 continues to grow. It is projected that by 2025, the number of people suffering from Alzheimer’s will have increased to 7.1 million and by 2050, the numbers will have already reached 13.8 million people. This is an alarming prediction since such numbers will hamper any form of research, and the chances of obtaining a medical breakthrough will be very slim. Alzheimer’s has no known cure, but there are medications if administered, can help the patients to cope with the disease (Newport, 2013). When the symptoms appear, it is advisable see a physician or a neurologist to plot the next course of action. A majority of diseases irrespective of their scope can be managed if detected early. Individuals living with Alzheimer’s need specialized care, and there are a few options for the families of the affected. They included home health care, nursing homes and assisted living facilities. Nursing homes provide personal and custodial care to the individuals who cannot do it themselves. Nursing homes are not the primary facilities for taking care of Alzheimer’s patients as well as other individuals with acute illnesses. Nursing homes bring about complaints from both the patients and the caregivers. Patients might feel that their autonomy had been eroded since they have no freedom

Eugene Smith Essay Example | Topics and Well Written Essays - 1000 words

Eugene Smith - Essay Example He began taking photographs in 1932 and early subjects included sports, aviation and the Dust Bowl. After studying at Notre Dame University for a year he joined the staff of Newsweek. In 1938 Smith became a freelance photographer working for Life Magazine, Collier's Weekly and the New York Times. In 1942 Smith became a war correspondent and spent most of the next three years covering the Pacific War. His most dramatic photographs were taken during the invasion of Okinawa in April 1945. On 23rd May Smith was seriously wounded by a Japanese shell fragment. He was taking a photograph at the time and the metal passed through his left hand before hitting the face. Smith was forced to return to the United States and he had to endure two years of hospitalization and plastic surgery. In 1947 Smith joined Life Magazine and over the next seven years produced a series of photo-essays that established him as the world's most important photojournalist. These included essays entitled: Country Doct or, Hard Times on Broadway, Spanish Village, Southern Midwife and Man of Mercy. Granted a Guggenheim Fellowship (1956-57), Smith began a massive picture essay of Pittsburgh. Smith's last great photo-essay, Minamata (1975), deals with the residents of a Japanese fishing village who suffered poisoning and gross disfigurement from the mercury wastes of a nearby chemical company. While photographing this project he was severely beaten by several local factory workers who were opposed to the revelations that his camera exposed. An extensive collection of his work was acquired by the Center for Creative Photography at the University of Arizona in 1976. Smith severed his ties with Life again over the way in which the magazine used his photos of Albert Schweitzer. Starting from his project to document Pittsburgh, he began a series of book-length photo essays in which he strove for complete control of his subject matter. This was followed by another large project on New York (1958-59). Smith also taught photojournalism at New York's New School for Social Research and was president of the American Society of Magazine Photographers. Complications from his consumption of drugs and alcohol led to a massive stroke, from which Smith died in 1978. Today, Smith's legacy lives on through the W. Eugene Smith Fund to promote "humanistic photography," which has since 1980 awarded photographers for exceptional accomplishments in the field. Of him, he says: "I am an idealist. I often feel I would like to be an artist in an ivory tower. Yet it is imperative that I speak to people, so I must desert that ivory tower. To do this, I am a journalist-a photojournalist. But I am always torn between the attitude of the journalist, who is a recorder of facts, and the artist, who is often necessarily at odds with the facts. My principle concern is for honesty, above all honesty with myself..." His Works and Analysis: "A Walk to Paradise Garden", 1946 Smith's war wounds cost him two painful years of hospitalization and plastic surgery. During these years he took no pictures and whether he would ever be able to return to photography was doubtful. Then one day, during his period of convalescence, Smith took a walk with his two children and even though it was still intensely painful for him to operate a camera, came back with one of the

Media-Mix Case Study Example | Topics and Well Written Essays - 1000 words

Media-Mix - Case Study Example Another advertising objective is encouraging the customers' recall of past satisfaction. Tapping familiar celebrities and making them do several commercials for the product would somehow make the audience believe that these are loyal and satisfied customers which further influences them into thinking that they, too, are satisfied with the products that they purchase from Victoria's Secret. However, most of the company's advertisements are for the purposes of modifying and reinforcing their target market's attitude towards their product. This is reflected on the controversial themes of their promotional materials. The issues thrown against the ads alone could show the audience how different the product is and how bold and daring one can seem by wearing that brand (Frisby, 2000). Promotion is a company's way of reaching out to a target market or audience to communicate a certain message. To be able to transmit the message and tow a large number of consumers to buy a product, a company or manufacturer should have the most effective and appropriate promotional strategies and techniques. Victoria's Secret, as a brand and a company, has had several critics regarding the advertisement of their products. Effective as they may be, some print or broadcast advertisements roused both negative and positive reactions from supporters and detractors. Some ads just do not work for a certain part of the audience. No matter how minor this part is, it is still a vital share of the consumers. Therefore, it is also helpful to experiment with the different types of media and combine the different advertising strategies. Since this company's target market include women, specifically those who go for the fashionable and sexy lingerie and underwear, advertisements include endorsers who exhibit qualities that most women want to have. For instance, some of the print ads show sexy supermodels- the ones with physiques that young ladies work hard for. Another is selling at a particular area where customers are said to abound. In the case of Victoria's Secret, this may include schools or recreational areas where girls often hang out. This and other broadcast advertisements do not only help promote and sell the product but also extend the company's public relations and help the company expand their business. In terms of keeping guest inflow in their website, the company has used one effective strategy. Using the site as a way to get the latest info about the products and having a live simulcast of a certain event over the internet greatly support the company's promotional agenda and sales and profit in general. Evaluation As mentioned earlier, advertisements do not always suit an audience's taste and are important factors in controlling a company's sales. If a certain market finds the advertisement appealing, the product's brand or company would easily stick to their minds. An informative advertisement would stimulate curiosity among the audience and lead them to check out the product. If the advertisement is persuasive enough, then more consumers would eventually buy and support the items that that company manufactures. There are different types of media to choose from when trying to promote a certain brand or product. The

The cinema of shane meadows

The cinema of shane meadows Over the last ten years Shane Meadows has helped to create a realistic portrayal of Working classed Britain. Director of films such as; Twenty four seven, A Room for Romeo Brass, Dead mans Shoes and This is England, Shane Meadows has helped to bring and to create social realist films for a new generation. His films stand side by side with more mainstream titles such as Brassed off, The Full Monty and Billy Elliot, each helping to bring the working classes and the social issues which they have faced to the forefront of National British cinema. What this essay intends to do is to explore Shane Meadows work as a director of British films, looking directly at how the past reflects the aesthetics and conventions within his films, how his cinema embodies the spirit of working classed identity and the social issues that are touched upon within his work and also why Meadows has become a popular film maker in contemporary Britain. The essay will look at three of Meadows films in particular; TwentyFourSeven, A Room for Romeo Brass and This is England, and will analyse the relationship that each film has with one another and why he has constructed an autobiographical take upon each of these films. Shane Meadows born in 1972 in Uttoxeter, Staffordshire, grew up within a working classed community. Meadows teenaged years were in a time which saw great political change for many people in the 1980s, with the working classes seeing only negative outcome to a new British government. Industrial areas, most notably within the North of England, saw the threat of unemployment around every corner and the very essence of working classed life was destroyed by Thatchers government, in her quest for a post industrial, classless society. Meadows experiences as a youth and the political and social changes that took place within the 1980s have been established throughout Meadows works. I think my 1980s is a richer time to draw on than any other.† Meadows has said when questioned on the reasons why his own childhood experiences are prominently featured in many of his films. As a British Realist film maker, Shane Meadows has distinctly borrowed from recognisable techniques and traditions from movements of the past. His notable influences are in the New wave cinema of film makers such as Karl Reisz, Lindsay Anderson and Tony Richardson from the 1960s and Mike Leigh and Ken Loach who have contributed to socio-realist cinema throughout the 1980s up until present day. What this has meant for Meadows is that his films are able to create a recognisable identity for a nation that people can be able to associate with. By creating a bond to the cinema of New wave and Realist cinema, Meadows is able to critique our nation through the use of a popular and recognisable aesthetic which is associated with many British dramas. The British New Wave cinema was the first step into creating a realist aesthetic in British narrative films. Through the inspiration of Documentary and the Italian neo-realist films that had come before, its film makers such as Karl Reisz and Lindsay Anderson were able to create a cinema which focused upon the intent of bringing social issues to the screen through realistic interpretations. Before they contributed to narrative cinema, Anderson and Reisz focused their talents upon Documentary, in which they created a movement, known at the time as the Free Cinema movement. Their approach was opposed to the traditional expository mode which British documentary film maker John Grierson produced within his production company; GPO pictures. Griersons documentaries sought to tackle the social problems of the working class misrepresented in British cinema, by siding with them. The voice of god narration and selective viewpoint was avoided within the Free Cinema movement, providing a poetic approach that stripped their documentaries of voice-overs and the right wing political stand point of the Grierson styled documentary, became left wing, criticising the British political system by focusing on the real working class, although, from a distance. I want to make people ordinary people, not just top people feel their dignity and their importance.† Lindsay Anderson said of his commitment to presenting the working class within his works. Although Griersons approach was highly criticised by the filmmakers of the free cinema movement, it was from Grierson himself who said that documentary was The Creative treatment of actuality.† This broadly used term could simply be interpreted as the way the film maker is able to create a display of artistic elements, from the construction of real people with real problems in real settings. Implicit in the Free cinema formulation were two related conceptions of freedom: on the one hand, a freedom from commercial constraint and, on the other, a freedom to give vent to a personal or unusual, point of view of vision.† The importance of the realist aesthetic within the Free cinema documentaries and the New wave narrative film was to make it clear that the artist was at the centre of the work. This did not necessarily mean that he was involved within the film itself, but the style of the film, ideologies and messages were that the film maker was trying to get across. The other importance was the ability to create the feeling of something new, to transform the real from Meer observation but to create a poetry which was able to work upon more than one level, and it was through the representation of a group of outsiders (the working class) that the film makers were able to do this. Films such as The Loneliness of the Long distance runner, A taste of Honey, A Sporting Life and Saturday Night, Sunday Morning, shifted the emphasis from middle class idealistic families, to a focus upon the youth living and working within industrial cities, situated in the Northern areas of England. The late 1950s/early 1960s became the first time since the Second World War that workers started to benefit from decent salaries and some, an almost disposable income. The youth in particular were able to separate themselves from their work lives and the authority figures that held a grasp over them, enabling them to spend their wages on the consummation of the latest in fashionable products. This is also true of New Wave films, which focused less on the importance of work within the lives of the characters but on their leisurely activities. The decline in the working class traditions and the rise of the working classed youth became notable. They were becoming defined not by what they produce but of what they consume and this was an indicator of the times. When looking at Saturday night Sunday morning by Karl Reisz, the main protagonist, Arthur Seaton (Albert Finney) may work within the confines of a factory, but when his working is shown, it is briefly and only to underline the important images or to support the leisurely aspect of his life. E.G. when he is finishing work. By wasting his money upon a sex, drugs and almost rock and roll lifestyle he is separating himself from the authority figures that keep him in his place during his working hours. Its not a unity of a working class that can be seen within this film or many of the New wave films of the 1960s, it is very much about issues of one person in particular, in the case of Saturday night, Sunday Morning, it is Arthur. Writer John Hill stated that Despite the ostensive commitment to represent the working class, the British New Wave, through their adoption of conventional narrativity and realism, tend to have the opposing effect, that is, the creation of an accentuated individualism.† The emphasis on the individual in this working class aesthetic of the New wave films may come down to the absence of work as a dominant presence. Instead it seems that the importance of working class life, as a youth, is separating themselves from the authority figures and dominant forces of work and instead making leisure and the way in which the characters separate themselves from work in their free time. In Meadows work, there is a felt presence of the New wave films throughout his work The focus upon just one main protagonist and their personal struggle rather than the united struggle of the working class is that it is extremely difficult to represent political problems within narrative film, without a need to create a bond to the personal effects that the political has upon the working class within realist cinema. But what exactly did the filmmakers do to try and create a believable and purposeful reality, and at once avoid the idealistic and theatrical approach that the Traditional Hollywood films employed? The main focus of reality in these New Wave films is by Meadows first feature film TwentyFourSeven was released in 1997. A resurgence in British Realism lead to a shift in focus for many of the films released within the 1990s. Whereas the films of the New Wave in the 60s, focused upon the employed youths personal struggle with working classed life and the hedonistic, anti-establishment attitude they portrayed in their leisurely pursuits and the 80s saw reactions against the Thatchers governments destruction of traditional working classed values and perceptions, the 90s took upon a different perspective, with Britain very much a post industrial nation, class now determined not what they made and who they were as a unified work force, but instead was now determined by what they consumed. This perspective now shifted upon the youth of today, from pre pubescent Children to teenagers growing up on rough, poverty stricken council estates. Unemployment has left the youth in the same position and status. Samantha Lay stated that Dramas focus more tightly on family relationships and partnerships. Poverty, unemployment and social exclusion are not the driving forces of their narratives, but are merely signalled as contributory factors to family strife, so that it is the working class family that has failed, not the state or capitalist society.† British Realist films focus upon the effect that politics have had upon the class system, specifically the working class whos inevitable decline since the 1950s has lead to an alienation of masculine identity and the emphasis as class as a unification. Meadows films are about the alienation of family life and the journey of finding a place to really belong. The perspective of a child or in the case of Twenty Four Seven; Young Adults, gives Meadow a chance to see the Working Class from a different perspective. What Meadows films do which many mainstream British films do not do is to question the stereotypical view of the average British person, by keeping to a low budget, Meadows keeps the focus upon the identities within his own regional upbringing. Unemployment plays a big role within the films of the British realist aesthetic that were made within the 1980s up until our contemporary time. Children and the youth are not affected in the same in which the adults are but their perspective is of the upmost importance. The period aspect to this is England, Twenty Four Seven and A Room for Romeo Brass gives you an aspect of political change. Within the 90s and the 2000s working class focused films created a way of escaping from the reality of the situation. Characters were able to find success from the economic situations that have dragged them down, most notably through entertainment. This can be seen within films such as Billy Elliot, Brassed off, The Full Monty and to an extent Trainspotting. Each of these films proved popular to the British movie going audience and tried showing how the working class could develop and escape from the working class life that had been dragging them down. Meadows approach, although not entirely pessimistic is about the positive which comes out of the negative situations, or the defeat of people. Unstable protagonists at the start of each three films, struggle with the uneven situations that their parents are entangled within, often dragging the children down with them. It is this alienation from family life which causes distress and change from these characters. Their questionable actions often ending in violence leads to the chance meetings in which potential father figures, genuinely interested in the emotional and physical state of the these characters help the characters from emotional unrest. In This is England, Shauns violent playground fight is caused from the mention of his Dads death. His walk home from school leads to the meeting of a Skinhead gang, most notably Woody who notes Shauns unhappy presence. His happy go lucky attitude and genuine care for Shaun makes him feel wanted in a place where hes alienated not only from family life but from being part of a sub culture which will accept him for who he is, which is evident from the mocking attitude of some of Woodys friends who are not as caring as Woodys father attitude to the situation is. In A Room for Romeo Brass, the fight between Romeo and the two boys leads to the rescue from Morell who is alerted from nearby. Again, the importance of chance turns a violent hateful act, into one with positive outcomes, in which children/teenagers are brought into the world of the adult. The Subculture is what draws the children into an adults world. Leisure drives them from the woes of family life and from the authority figures which are bringing them down. The masculine father figures within Meadows films help to refocus the output of the violence of the youth that they have taken under their wing. The troubled teenagers caught in violent episodes, find new ways in which to focus their negative energies. This frustration for life in post industrial estates, in which domestic problems of parents causes great angst often leads to violence. By refocusing these ill thoughts and actions through healthy attitudes, the Father figure is able to guide the youth away from everything that is holding them back. Woodys optimistic and peaceful father figure for fatherless tearaway Shaun in This is England, enables his alienation from a social perspective to be reinstated into a group in which he belongs. The anger and frustration of these Skinhead youths does not lead to the targeting of people, but of decrepit, rundown buildings on council estates.

Biography of Nellie Tayloe Ross Essay -- Bio Biograhies Nellie Ross E

Biography of Nellie Tayloe Ross Nellie Tayloe was a woman of remarkable skills, responsibility and endurance. Before she became the first woman governor of the United States, Nellie was a kindergarten teacher and a presenter of informative papers at her local women’s group. She also helped her husband with his law practice as well as his governorship. Nellie was born in Missouri in 1876. â€Å"She was the sixth child and the first daughter of James and ‘Lizzie’ Tayloe† (Scheer, 2). Nellie was very private about her childhood and little is known about the family from which she came. The only story of her childhood that she ever shared was of her home being destroyed by a fire (Scheer, 1). In 1902, she became Nellie Tayloe Ross after marrying a successful lawyer and future governor of Wyoming, William Bradford Ross. Nellie was a stay at home mother with their four sons; twins George and James Ambrose, Alfred, who died at the age of ten months, and William Bradford II (Mackey, 26). In 1924, just one month before the general election, William Bradford Ross died of complications from appendicitis, leaving the democrats without a candidate (Thompson, 36-37). Many of Nellie’s friends, â€Å"... encouraged her to seek the Democratic Party’s nomination† (Mackey, 26). Analysis once suggested that â€Å"... women are put forward when their parties feel that they have little chance of winning and nothing to lose by nominating a controversial candidate† (Thompson, 36-37). Ross defeated Sullivan (the republican candidate) by more than 8000 votes. During her reign as Governor of Wyoming Nellie Tayloe Ross addressed many issues including the state’s budget deficit. While looking into the mining operations, Ross found that a lot of proper... ... A women’s dormitory, on the campus of the University of Wyoming, was named after her: Nellie Tayloe Ross Hall. In 1977, at the age of 101, Nellie died from a fall in her apartment near Washington D.C.. She was buried in Cheyenne, Wyoming (Scheer, 213-214). Her contributions to Wyoming helped pave the way for future generations of politicians as well as women and women’s rights. Works Cited: Mackey, Mike. "Nellie Tayloe Ross and Wyoming Politics."

Super Resolution Mapping To Determine Shoreline Position Environmental Sciences Essay

Coastal zone and shoreline monitoring is an of import undertaking in sustainable development and environmental protection. For coastal zone monitoring, shoreline extraction in different times is a cardinal work. Features of H2O, flora and dirt make the usage of the images that contain seeable and infrared sets widely used for coastline function Conventionally, photogrammetric technique is employed to map the tide-coordinated shoreline from the aerial exposure that are taken when the H2O degree reaches the coveted degree. On site study taken at these H2O degrees are more expensive to obtain than distant feeling imagination. With the development of distant feeling engineering, orbiters can capture high-resolution imagination with the capableness of bring forthing shoreline place. In recent old ages, satellite remote feeling information has been used in automatic or semi- automatic shoreline extraction and function. Braud and Feng ( 1998 ) evaluated threshold degree slice and multi-spectral image categorization techniques for sensing and word picture of the Louisiana shoreline from 30 m spacial declaration Landsat Thematic Mapper ( TM ) imagination. They found that thresholding TM Band 5 was the most dependable methodological analysis. Frazier and Page ( 2000 ) quantitatively analyzed the categorization truth of H2O organic structure sensing and word picture from Landsat TM informations in the Wagga part in Australia. Their experiments indicated that the denseness slice of TM Band 5 achieved an overall truth of 96.9 per centum, which is every bit successful as the 6-band maximal likeliness categorization. Besides multi-spectral orbiter imagination, SAR imagination has besides been used to pull out shorelines at assorted geographic locations ( Niedermeier, et A l. 2000 ; Schw & A ; auml ; bisch et Al. 2001 ) . While the really all right spacial declaration detectors ( e.g. IKONOS ) offers increased spacial declaration, the imagination from such systems is frequently inappropriate for many users, peculiarly if a big country is to be mapped ( Mumby and Edwards, 2002 ) . Therefore, if constrained to utilize fine-to-moderate spacial declaration ( 0.10 m ) imagination, there is a desire to map the water line at a subpixel graduated table. In such state of affairss the purpose is, hence, to deduce a map that depicts the characteristic of involvement at a graduated table finer than the informations set from which it was derived, which may be achieved through a super-resolution analysis ( Tatem et al. 2001, Verhoeye and De Wulf 2002 ) . 3.2 Test site The work focused on a 38 kilometer stretch of along a seashore off the North West Cape in the north west seashore of Western Australia ( Figure 3.1 ) . The shoreline was characterized by different beaches such as flaxen beaches, muddy and drop and facing to the Exmouth Gulf in the Indian Ocean. Exmouth Gulf is really shallow, with an mean deepness of about 10 m and northerly confronting drowned river vale in northwest Australia reverse estuarine embayment on the northwest shelf of Australia. The tidal scope is less than 2 m and varies little between neap and spring tides. The Exmouth part is exposed to preponderantly south to southeasterly air currents throughout the twelvemonth ( Bureau of Meteorology, 1988 ; Lough, J.M. , 1998.

During spring and summer by and large moderate ( 21-30 kilometers per hour ) southward winds dominate, and fall and winter records show by and large lighter ( 11-20 kilometers per hour ) air current velocities with fluctuations between the dominant sou'-east air current and north to northeast air currents. The air current government is controlled chiefly by the interplay of the southeasterly trade air current system and the west coast-generated sea zephyr, in concurrence with a local sea zephyr developed within the Gulf. australia1-edit.JPG Figure 3.1: Location of shoreline trial site ( shaded ) and selected as had scope of morphologies in a survey country. 3.3 Data sets The survey used a series of harsh spacial declaration National Oceanic and Atmospheric Administration ( NOAA ) images over survey site to bring forth a ace declaration image. For this survey, the shoreline was defined as the place of the boundary between H2O and land at the clip satellite imagery acquisition. The NOAA series of orbiters which each carry the Advanced Very High Resolution Radiometer ( AVHRR ) detector. These detectors collect planetary information on a day-to-day footing for a assortment of land, ocean, and atmospheric applications. Specific applications include forest fire sensing, flora analysis, weather analysis and prediction, climate research and anticipation, planetary sea surface temperature measurings, ocean kineticss research and hunt and deliverance ( CCRS, 1998 ) . 3.3.1 AVHRR detector features AVHRR informations set is comprised of informations collected by the AVHRR detector and held in the archives of the Geoscience Australia. Carried aboard the National Oceanic and Atmospheric Administration`s ( NOAA ) Polar Orbiting Environmental Satellite series, the AVHRR detector is a broad-band, 4- or 5-channel scanning radiometer, feeling in the seeable, near-infrared, in-between infrared and thermic infrared parts of the electromagnetic spectrum. It provides planetary on board aggregation of informations over a 2399 kilometer swath. The detector orbits the Earth 14 times each twenty-four hours from an height of 833 kilometer. In this survey, NOAA images acquired from Geoscience Australia and NOAA antenna in Alice Springs permits acquisition of twenty-four hours and night-time base on ballss. There are usually about two day-time base on ballss per orbiter and two night-time base on ballss per orbiter. The detector parametric quantities as shown Table 3.1. Merely informations acqui red in Channel 2 ( 0.725 – 1.00 Â µm ) was used for this survey because land H2O boundaries clearly seen on the image. Table 3.2 shows an AVHRR Spectral Characteristics.

The Landsat way was 115 and WRS Row 075 were geometrically corrected and georeferenced to WGS 84 ( universe co-ordinate system ) .o Georeference imagination is defined imagination which has been corrected to take geometric mistakes and transformed to a map projection. Georeferenced image rectification can take one of the two signifiers, systematic and preciseness. Systematic rectification involves utilizing orbital theoretical accounts of the orbiter plus telemetry informations to happen the approximate relationship between the image and the map coordinates. Precision rectification uses land control points to register the image to absolute geographical co-ordinates. In other words, in a geo-referenced image the pels and lines are non aligned to the map projection grid geo-referenced image the pels and lines are non aligned to the map projection grid . A Landsat 5 TM scene has an instantaneous field of position ( IFOV ) of 30 m by 30 m ( 900 square metres ) in bands 1 through 5 and band 7, and an IFOV of 120 m by 120 m ( 14,400 square metres ) on the land in set 6. Merely band 4 ( 0.76 – 0.90 Â µm ) was used for delineate a shoreline. landsat1.JPG Figure 3.2: Landsat 5 TM informations over study country. Acquired day of the month: 24 August 2007 3.4 Method In the context of ace declaration techniques, it is assumed that several harsh spacial images can be combined into a individual all right spacial image to increase the spacial declaration content. The harsh spacial images can non all be indistinguishable and there must be some fluctuation between them, such as translational gesture analogue to the image plane ( most common ) , some other type of gesture ( rotary motion, traveling off or toward the camera ) , or different screening angles. In general, ace declaration can be broken down into two wide parts: I ) enrollment of the alterations between the harsh spacial images, and two ) Restoration, or synthesis, of the harsh spacial images into a all right spacial image ; this is a conceptual categorization merely, as sometimes the two stairss are performed at the same time. In this survey, the aim is to bring forth all right spacial declaration image from multiple harsh declaration images. Fine spacial declaration image has been applied with object designation methods which may build with regard to image enrollment and super-resolution building. All parametric quantities are used iteratively and do object designation secured from mistake response and been processed in hardiness, accurate and preciseness manner. 3.4.1. Image Registration Image enrollment is the procedure of covering two or more images of the same scene taken at different times, from different point of views or by different detectors. Image enrollment is a important measure in all image analysis undertakings in which the concluding information is gained from the combination of assorted informations beginnings like in image merger. Image enrollment consists of following four measure ; characteristic sensing, characteristic matching, transform theoretical account appraisal and image resampling and transmutation. i. Geometric Registration The geometric deformations present in airborne remotely perceived images may be categorized into system-independent and system-dependent deformations. The system independent deformations are caused by the gesture of the detector and by surface alleviation. Figure 3.3 shows on instance of images which are related by a planar projective transmutation or alleged planar homography. There are two different state of affairss where ( a ) images of a plane viewed under arbitrary camera gesture and ( B ) image of an arbitrary 3D scene viewed by a camera revolving about its ocular Centre or zooming. Figure 3.3: Two imaging scenarios for which the image-to-image correspondence is captured by a planar homography ( Capel and Zimmerman, 2003 ) Under a planar homography, points are mapped as: ten ‘ = Hx, where ten ‘ correspondence point of mention points x in other image and H is a 9 transmutations projection. The different of planar homography based on transmutation matrix attack below: or equivalently ; ( 3.1 ) ten ‘ = Hx The tantamount non-homogeneous relationship is ( 3.2 ) The scenario depicts in which homography will happen when a freely traveling camera views a really distant scene, such instance in airborne remote sansing ( Forte and Jones, 1999 ) . ( two ) Photometric Registration Photometric enrollment refers to the process by which planetary photometric transmutations between images are estimated. This enrollment traveling to use a theoretical account which allows for an affine transmutation ( contrast and brightness ) per RGB shows below. 3.3formula3.GIF Where, r1, g1, b1 are RGB channel in image 1 while r2, g2, b2 indicate RGB channel in image 2. Matrix A is used to calculate the remainder of brightness and contrast ? . Image enrollment of homography image concludes in Figure 3.4, last two stairss iterate until the figure of itelaration is stable. method.GIF Figure 3.4: Procedure to gauge a homography between two images. In order to deduce ace declaration image utilizing multiple series of low declaration images, all images need to register at the same time and corrections may easy implemented. Block bundle accommodation traveling to be considered as the best calculator to calculate all braces of back-to-back frames in the input sequence. Parameters such as interlingual renditions, rotary motions, graduated table, contrast and brightness, characteristic base enrollment, RANSAC ( RANdom SAmple Consensus ) and fiting could be done at the same time in every image brace. Generative image formation theoretical account is the best image formation algorithms which may see geometric transmutation of n images, point spread map which uniting effects of optical fuzz and gesture fuzz, down-sampling operator by a factor S where trying rate traveling to be entree, scalar light parametric quantities and observation noise. This theoretical account is generalized as follows: formula4.GIF f = mulct spacial declaration image gn = nth observed harsh spacial declaration image ?n = geometric transmutation of n-th image H = point dispersed map sv = down-sampling operator by a factor S ?n, ?n = scalar light parametric quantities ?n = observation noise 3.5 Hard categorization To distinguish between land and H2O organic structure a difficult classifier was applied to the fake coarse spacial declaration orbiter detector imagination. The maximal likeliness difficult classifier used to sort the harsh spacial declaration imagination ( NOAA AVHRR ) . The same preparation sites used in sorting the all right spacial declaration image ( cite informations ) were used ( Figure 4.5 ) . Using these developing sets the 20 m imagination was classified to 2 categories ( land and H2O ) . The resulting image ( Figure 3.7 ) would subsequently be analysed to find the positional mistake between the predicted shoreline location and the existent location based on the land informations. densitynooa.jpg ( a ) densitylandsat.jpg ( B ) Figure 3.5: ( a ) 1100 m spacial declaration and ( B ) 30 thousand spacial declaration classified imagination 3.7 Soft Categorization Difficult categorization techniques have been popular in distant feeling but they merely assign one category to a certain pel ( Jensen, 1996 ) . As shoreline pels normally contain a mixture of land and H2O categories, information within a pel is lost. A major job for accurate reading of distant feeling informations is related to the fact that pels may incorporate more than 2 categories which would merely be realised from land activities ( Foody, 1992. To turn to this job research workers have developed methods to deduce estimations of the sub-pixel category composing through the usage of techniques such as mixture modeling and soft or fuzzed categorizations ( Foody, 1996 ) . Soft classifiers allow pels to hold variable grades of rank to multiple categories. Soft classifiers assign a rank class between 0 and 1 to each category in a pel. This allows a pel to be associated to multiple categories instead than merely to one category as in conventional difficult classifiers. The end product of the soft categorization for each pel was an indicant of the comparative rank to the two categories and, in the country where rank was greatly assorted, this was taken as an estimation of the relative screen of the constituent categories ( figure 3 ) . noaa.jpglegend.GIF Figure 3.6: End product of soft categorization. The gray graduated table indicates the grade of rank to the land category. 3.8 Super declaration Maping The water line was mapped from the ace declaration image generate from the series of harsh spacial declaration image.. The same preparation sites were used in all the categorizations. As a benchmark, a conventional difficult categorization was used to foretell the water line from the fake image. The water line was fitted to the derived end product of this categorization by weaving it between pels allocated to the different categories. sr.JPG ( a ) density_sr.JPG ( B ) sr.JPG ( degree Celsius ) Figure 3.7: Ace declaration technique ( a ) individual image ( B ) difficult categorization of ace declaration image ( degree Celsius ) water line word picture. 3.tif ( a ) 5.tif ( B ) 12a.tif ( degree Celsius ) 15a.tif ( vitamin D ) 20.tif ( vitamin E ) 20.tif ( degree Fahrenheit ) Figure 3.8: End product of ace declaration technique ( a ) 3 images ( B ) 5 images ( degree Celsius ) 12 images ( vitamin D ) 15 images ( vitamin E ) 30 images ( degree Fahrenheit ) 50 images. 3.8 Positional Error Analysis End product from a difficult and soft categorization produces images with pels values stand foring the proportion of a certain category within pels. But it does non bespeak where within a pel these categories are located. To turn to this job, methods of administering the proportion within each pel to different categories were explored. The truth of shoreline maps generated at each spacial declaration from application of the difficult categorization, soft categorization and ace declaration method from multiple images were analysed for survey country ( Figure 3.1 ) . For each infusion and coarse-spatial declaration image, the truth of the shoreline anticipation derived was determined by comparing the to the Landsat 5 TM informations for every meter of the shoreline ( Table 3.3 ) The positional truth along the 38km length of shoreline in each infusion is shown in Table 3.3: Positional truth of the each method.

Number of Protons, Neutrons, and Electrons in an Atom

Number of Protons, Neutrons, and Electrons in an Atom The three parts of an atom are positive-charged protons, negative-charged electrons, and neutral neutrons. Follow these simple steps to find the number of protons, neutrons, and electrons for an atom of any element. Key Takeaways: Number of Protons, Neutrons, and Electrons Atoms are made of protons, neutrons, and electrons.Protons carry a positive electrical change, while electrons are negatively charged, and neutrons are neutral.A neutral atom has the same number of protons and electrons (charges cancel each other out).An ion has an unequal number of protons and electrons. If the charge is positive, there are more protons than electrons. If the charge is negative, electrons are in excess.You can find the number of neutrons if you know the isotope of the atom. Simply subtract the number of protons (the atomic number) from the mass number to find the remaining neutrons. Get Basic Information About Elements Youll need to gather basic information about the elements to find the number of protons, neutrons, and electrons. Fortunately, all you need is a periodic table. For any atom, what you need to remember is: Number of Protons Atomic Number of the Element Number of Electrons Number of Protons Number of Neutrons Mass Number - Atomic Number Find the Number of Protons Each element is defined by the number of protons found in each of its atoms. No matter how many electrons or neutrons an atom has, the element is defined by its number of protons. In fact, its actually possible to have an atom consisting of only a proton (ionized hydrogen). The periodic table is arranged in order of increasing atomic number, so the number of protons is the element number. For hydrogen, the number of protons is 1. For zinc, the number of protons is 30. The element of an atom with 2 protons is always helium. If you are given the atomic weight of an atom, you need to subtract the number of neutrons to get the number of protons. Sometimes you can tell the elemental identity of a sample if all you have is the atomic weight. For example, if you have a sample with an atomic weight of 2, you can be pretty certain the element is hydrogen. Why? Its easy to get a hydrogen atom with one proton and one neutron (deuterium), yet you wont find a helium atom with an atomic weight of 2 because this would mean the helium atom had two protons and zero neutrons! If the atomic weight is 4.001, you can be confident the atom is helium, with 2 protons and 2 neutrons. An atomic weight closer to 5 is more troublesome. Is it lithium, with 3 protons and 2 neutrons? Is it beryllium with 4 protons and 1 neutron? If youre not told the element name or its atomic number, its hard to know the correct answer. Find the Number of Electrons For a neutral atom, the number of electrons is the same as the number of protons. Often, the number of protons and electrons is not the same, so the atom carries a net positive or negative charge. You can determine the number of electrons in an ion if you know its charge. A cation carries a positive charge and has more protons than electrons. An anion carries a negative charge and has more electrons than protons. Neutrons do not have a net electric charge, so the number of neutrons does not matter in the calculation. The number of protons of an atom cannot change via any chemical reaction, so you add or subtract electrons to get the correct charge.  If an ion has a 2 charge, like Zn2, this means there are two more protons than electrons. 30 - 2 28 electrons If the ion has a 1- charge (simply written with a minus superscript), then there are more electrons than the number of protons. For F-, the number of protons (from the periodic table) is 9 and the number of electrons is: 9 1 10 electrons Find the Number of Neutrons To find the number of neutrons in an atom, you need to find the mass number for each element.  The periodic table lists the atomic weight for each element, which can be used to find mass number, For hydrogen, for example, the atomic weight is 1.008. Each atom has an integer number of neutrons, but the periodic table gives a decimal value because it is a weighted average of the number of neutrons in the isotopes of each element. So, what you need to do is round the atomic weight to the nearest whole number to get a mass number for your calculations.  For hydrogen, 1.008 is closer to 1 than 2, so lets call it 1. Number of Neutrons Mass Number - Number of Protons   1 - 1 0 For zinc, the atomic weight  is 65.39, so the mass number is closest to 65. Number of Neutrons 65 - 30 35

The Invention and History of the Altimeter

The Invention and History of the Altimeter The altimeter is an instrument that measures vertical distance with respect to a reference level. It can give the altitude of the land surface above sea level or the altitude of an airplane over the ground. French physicist  Louis Paul Cailletet  invented the altimeter and the high-pressure manometer. Cailletet was the first to liquefy oxygen, hydrogen, nitrogen, and air in 1877. He had been studying the composition of gases given off by iron in the blast furnace of his fathers ironworks. At the same time, Swiss physician Raoul-Pierre Pictet liquefied oxygen using another method. Cailletet had an interest in aeronautics, which led to developing an altimeter to measure the altitude of an airplane. Version 2.0 AKA the  Kollsman Window In 1928, a German-American inventor named Paul Kollsman changed the world of  aviation with the invention of the worlds first accurate barometric altimeter, which was also called the â€Å"Kollsman Window.† His altimeter converted barometric pressure into the distance above sea level in feet. It even allowed pilots to fly blind. Kollsman was born in Germany, where he studied civil engineering. He emigrated to the United States in 1923 and worked in New York as a truck driver for Pioneer Instruments Co. He formed the Kollsman Instrument Company in 1928 when Pioneer didnt accept his design. He had then-Lieutenant Jimmy Doolittle conduct a test flight with the altimeter in 1929 and was eventually able to sell them to the United States Navy. Kollsman sold his company to the Square D Company in 1940 for four million dollars. The Kollsman Instrument Company eventually became a division of Sun Chemical Corporation. Kollsman also went on to file hundreds of other patents, including those for converting salt water into fresh water and for a slip-resistant bathroom surface. He even owned one of the earliest ski areas in the United States, Snow Valley in Vermont. He married actress Baroness Julie Luli Deste and purchased The Enchanted Hill estate in Beverly Hills. The Radio Altimeter   Lloyd Espenschied invented the first radio altimeter in 1924.  Espenschied was a native of St. Louis, Missouri who graduated from the Pratt Institute with a degree in electrical engineering. He was interested in wireless and radio communications and worked for telephone and telegraph companies. He eventually became the director of high-frequency transmission development at Bell Telephone Laboratories.   The principle  behind how it works involves monitoring a beam of radio waves transmitted by an aircraft and their time to return as reflected from the ground to calculate altitude above the ground. The radio altimeter differs from the barometric altimeter in showing altitude above the ground below rather than above sea level. That is a critical difference for improved flight safety. In 1938, the FM radio altimeter was first demonstrated in New York by Bell Labs. In the first public display of the device, radio signals were bounced off the ground to show pilots the altitude of an aircraft. Besides the altimeter, he was also the co-creator of the coaxial cable, an important component of television and long-distance telephone service. He held over 100 patents in communications technology.

Operations Management and Tesco Essay Example | Topics and Well Written Essays - 1250 words

Operations Management and Tesco - Essay Example Signboards with directional arrows were found to hang from the ceiling. Commodities were segregated on the basis of different parameters, each type being found at one place. The positioning of items was so done as to optimise space and also allow easy access to the customers. An interesting feature of the store is the open space that facilitates movement of products as well as customers. The entire arrangement has been designed in a way that ensures minimum collision between people moving inside the store. Surveillance cameras are installed at strategic points that keep an eagle eye on possible shop lifters. In operations management, the 4 V's are commonly defined as volume, variety, variation and visibility. In a large supermarket like that of Tesco's, all of them could be sensed, though in varying proportion. (Slack N., et al, 2007) The supermarket offers only one service that being providing commodities to customers. However, this is not the all. The uniqueness of the super market lies in the fact that it provides a plethora of goods and other necessary items for sale. It allows the customers the freedom to shop groceries, garments, accessories, cosmetic products, beverages and toiletries all at the same place. In addition to this, customers can also enjoy free home delivery services in case their purchase bills exceed certain pre determined limits. The volume of operations is thus, very high. Continuing from the volume analysis, the variety of services that a customer receives from the supermarket is high. It also needs to be mentioned that it depends on the customer whether she would like to enjoy the whole range of services provided. For example, many people were seen to visit the garments and electronics goods section but none of them purchased from there. In the strictest sense of the term the variety is very high. The store which was visited had maximum number of customers purchasing grocery and food items. Variation in sales happens depending on the product. Generally, food items have a moderate level of demand. Garments are in high demand only in certain seasons. However, variation in sales was also experienced throughout the day. Towards the evening, there was a rise in the number of customers purchasing hard drinks, beer and fruit shakes. Visibility, as defined in theories of operation management, is very low. Customers seldom can see how the shelves are getting filled up or the source from where frozen foods are obtained. Most of the rearrangement is done during the early morning or late night after the store gets closed for customers. The Layout, Flow and Use of Process Technologies In a supermarket, the layout and flow of various products are of paramount importance. It has to be borne in mind that placing of the products plays an important role both for the customers as well as the service provider. In the visited store, the layout was more like a process layout. Items of same kind were placed at one place. Among the items of same kind, the heavier ones were placed in a manner that would make it easy for the customer to carry it. Personal items and toiletries were found to be arranged in columns, the bigger packets forming the base and the smaller ones

Global economic Assignment Example | Topics and Well Written Essays - 6000 words

Global economic - Assignment Example Simon, an economist, and P. Ehrlich, a biologist (Economist 2011). In the book of Ehrlich under the title ‘Population bomb’ reference is made to five metals, the price of which was expected to increase in the following ten years because of the increase of population globally; a bet has been set between Ehrlich and Simon who opposed the above argument, noting that no such increase would take place, a view that was verified up to 1990s (Economist 2011). According to the article, if the above issue were reviewed now, a different result would be revealed. Indeed, if the views of these scientists were compared today, Ehrlich would have won the bet (Economist 2011). In other words, the article aims to highlight the different effects of growth of global population, as reported through the decades. It is noted that in the past, the effects of the increase of population globally would be less negative for the environment compared to today; this view is based mostly on the argumen t of the World Bank that the global food production would have to increase by about 70% by 2050, so that the food needs of global population, estimated to 9 million in 2050, to be covered (Economist 2011). However, it has been proved that areas with stable population, like Europe and USA (Economist 2011) tend to affect more the global climate, compared to countries where the level of population is unstable. Under these terms, it is suggested that the control on the rate of growth of population should be developed both at state and at family level. 2nd version The rate of increase of population globally has been often considered as related to the economy of countries worldwide. At the same time, the effects of increase of population on global climate seem to be important. However, these views have not been standardized through the decades. For example, according to the book ‘The Population Bomb’ of Ehrlich, the increase of global population between 1980 and 1990 could le ad to the increase of the price of five metals: ‘copper, chromium, nickel, tin and tungsten’ (Economist 2011). By 1990, no such increase occurred, a fact that was already highlighted by Ehrlich opponent, Julian Simon (Economist 2011). In the years that followed, a different trend appeared: it was made clear that the increase of global population could lead to the increase of food required for covering people’s daily food needs, an issue highlighted by the World Bank (Economist 2011). In addition, it was proved that the increase of global population could negatively affect the environment. It seems though that the economic and environmental effects of the increase of global population are more intensive in rich countries, like USA and China. Introducing a birth-control policy, as in China, would minimize such risks. Still, the article notes that the control on global population should be rather based on appropriate family planning and less on the intervention of s tate, which can lead to severe demographic and economic turbulences, as in the case of China. In the above country, the one-child policy promoted by the government has helped to control the excessive increase of population, which would have adverse effects on the country’s economy and climate, but this policy is expected to lead to the radical decrease of the country’s working population in the near future (Economist 2011).
