Bio-Terrorism Research and Development - Essay Example These pathogens have high probabilities of bioterrorism use because they can be disseminated fast and without difficulty; would simply need minimal amounts to cause and spread diseases; and would cause high levels of morbidity and mortality (Perlin, 2008). Category A agents, being the highest risk agents, are top priority in research efforts. Category B agents create the second highest threat.  Category C agents are the emerging communicable disease hazards (â€Å"Potential Bioterrorism Agents,â€Å" 2010). Biological agents such as anthrax, botulism, plague, smallpox, tularemia, and viral hemorrhagic fevers (â€Å"NIAID report claims great progress in biodefense research,† 2010), are cheap substitutes to conventional weapons. Preferred by terrorists, these pathogens have easy accessibility; rapid production and distribution; low detection and high potentials for causing national disturbance (â€Å"Potential Bioterrorism Agents,â€Å" 2010). Since 2002, the National Institute of Allergy and Infectious Diseases (NIAID) has shown remarkable progress in the development of measures to counteract bioterrorist attacks. Basic research programs comprise the latest designation and financial support of eight regional academic centers for biodefense research and rising transmittable diseases. All strains of pathogen genomes with high-risk for bioterror use are sequenced and determined of possible viral and protozoal bioterrorism infection. Researchers are given grants to study the deterrence, identification, and cure of diseases caused by bioweapons. The NIAID research targets on the development of effective vaccines and precise diagnosis (â€Å"NIAID report claims great progress in biodefense research,† 2010). Mucosal immunities are studied on areas of infection, such as the respiratory organs and oral passages since potential bioweapons are most likely to infect those areas (â€Å"Introduction to Biodefense Research,â₠¬  2010). Proposed efforts to

Industrialization and Appalachia Essay Example for Free

Industrialization and Appalachia Essay Industrialization and Appalachia The Industrial revolution did not â€Å"skip over† Appalachia but the native mountain people did not benefit from the effects of industrialization and were left in a worse situation. The stereotype of the Appalachian people that was formed prior to the industrialization era was that mountain people were noble, savage, independent, proud, rugged, dirty and uneducated. The industrialists to promote economic development and industrialization of Appalachia used this backward image of the Appalachian people. They believed that the native Appalachian people were incapable of developing the Appalachian Mountains natural resources on their own. However in trying to keep up with the modern world during the industrial revolution the people of Appalachia were doomed to their pre-industrial image. Until the era of industrialization Appalachia was a region of small, open-country communities, concentrated in valleys, coves and hollows. Each community of farms was self-sufficient socially and economically. The focus of a self-sufficient farmer was that of survival by working in their own crops and hunting or raising livestock for food. They tended to have large families to help with all the demands of the farm. After the Civil War northerners came into the southern Appalachian Mountains, and many were surprised by what they found. They found a multitude of mineral and timber wealth as well as a romantic beauty of the mountain landscape. Capitalists responded to this discovery and began to industrialize the Appalachian Mountains for their own profit. Capitalists believed that the Appalachian people were too backward to know that they were sitting on an abundance of resources so they manipulated the mountaineers into selling large amounts of land for basically nothing. As Eller wrote in his book Miners, Millhands and Mountaineers, â€Å"some sold entire mountains for a mule, horse or rifle†. Industrialization depended first upon the building of an adequate transportation system into, out of, and within the mountain regions of the South. The railroad was built and it opened the doors to the full exploitation of the mountains natural resources. Coal and timber extraction were the primary resources that drove the Industrial Revolution in Appalachia. The extraction of these resources required the employment of the Appalachian farmer. The mountaineer left their farms for wage employment  and became dependent on that. The uncontrolled flow of the coal and timber industry took up huge plots of farmland and forced families to move to the mining towns. With the presence of the coal and timber companies in place, the mountaineer could not hope to be more than barely self-sufficient. The area industrialized without developing sufficient infrastructure to sustain itself, dooming the mountain people to poverty. The average mountaineer had been an independent sort of person, running his own farm, raising a family and building his own future. When brought into coal, timber, and textile towns, he was at the mercy of his employer. The mountaineer became totally dependent on his employer and was forced into terrible conditions. Besides this dependence to his employer the mountaineer could not go back to his old home place and farm again because the cutting of timber ruined agriculture. â€Å"One of the most important results of industrialization in Appalachia has been the negative impact it has had on the long-term economic health of the region. None of the industries in Appalachia, and especially not the coal industry, encouraged rival or spin-off economic development during their boom years. The effect has been sporadic economic growth without real economic development† (A Handbook to Appalachia, 15). In Miners, Millhands and Mountaineers, Ellers thesis was that while Appalachia had undergone industrialization, the region itself failed to modernize. He argues that during and after the industrialization process mountain people lost their independence and self-determination of their ancestors, without becoming full participants in the benefits of the modern world. The mountain people found that the growing prosperity had bred greater dependence on the system beyond their control. Worst of all, none of the wealth the industrialists stripped from the mountains remained there. The industrial revolution was not properly development in Appalachia and it left the Appalachian people poor and barely able to care for themselves. So it is obvious that, in trying to keep up with the modern world, the people of Appalachia were doomed to their pre-industrial image or stereotype. Works cited 1.

Confronting Death in Richard Wilburs The Pardon Essay -- Wilbur The P

Confronting Death in Richard Wilbur's The Pardon Death is the issue at the heart of Richard Wilbur's poem "The Pardon." This is apparent from the opening line, "My dog lay dead five days without a grave." What is not immediately apparent, however, is that this is not simply a poem about a young boy's sadness over the loss of his dog. What Wilbur discusses in this piece is much more profound, cutting through the superficialities of death and confronting fears and doubts that all of us experience at different points in our lives. This is a poem about atonement, about facing the mistakes of the past and confronting them directly. More specifically, it is about reconciling ourselves with death and everything that life's deepest tragedies entail. The adult narrator of the poem is haunted by his past, unable to cope with feelings and emotions that he had as a youth. He even seems to have attempted to repress a portion of his life. However, as a result of a chillingly realistic dream, he is at last forced to face what he thought was burie d for good. The realization that comes because of this, the realization that death is not something to run from, is the true meaning of the poem and the crux of what Wilbur is trying to say to the reader.   Ã‚  Ã‚  Ã‚   "The Pardon" can be divided into three distinct parts. The first sub-section is made up of stanzas one and two, which detail a tragic event that occurred in the life of the narrator when he was ten years old: the death of his dog. It is in these first eight lines that the narrator tries to give the reader an understanding of what he felt when this happened. He uses very descriptive words and phrases, providing vivid imagery of the various sights, smells, and sounds that he experienced. H... ...ightful look into death and the fears and doubts that it induces within all of us. The narrator of the poem is a man who has never been able to confront death, beginning with the loss of his dog at the age of ten. He has chosen to avoid it his entire life, rather than attempting to understand it. It is finally as an adult that a vivid dream causes him to finally face his fears: he sees his dog rising out of its grave and begins to ask it for forgiveness. The dog in the dream can be seen as a representation of his trepidation. Once he is able to confront it and ask for its pardon, he can finally begin to cope with the idea of death.    Works Cited Jarrell, Randall. "Fifty Years of American Poetry."

Development of New Space Vehicles for Future Space Tourism

A lot of people nowadays consider ordinary space travel and tourism as an outlandish vision for the next century and for the upcoming future. On the other hand, scientists and futurists say that space tourism is a possible subject and possibility that current aeronautics and space science will lead to in the next few years. Other people view space tourism as a complete waste of resources given the multitude of earthbound problems that needs to be solved before having a nice flight back and forth from space. In spite of all these foreseen problems, space tourism is a reality that many people await and envision. These people comprise of visionaries and business men who are currently building the required facilities to make space tourism possible and who also have the courage to believe in the idea that space tourism can be a reality.Space tourism is essentially spaceflight which has been funded by personal interests for the purposes of personal satisfaction. Likewise, space tourism is very similar to any tourist vacation in the Bahamas or in the Caribbean or in any destination in Earth. Some of the personal reasons for spending on space tourism comprise the very unique experience of having been into space, the experience of weightlessness, the ability to view the curvature and disk of the earth, as well as the status of having been one of the few people who have been space tourists.ObjectivesTo be able to gain knowledge from the space travel and tourism. To be able to explore the different possibilities in travelling through space. To be able to assess and evaluate current space travel methods and technology available today. To be able to assess the output of space tourism as a business. To be able to identify the problems encountered as a consequence to space travel and tourism proposals. To be able to briefly name and briefly discuss the possible future technologies for space travel. Literature CitedSpace Tourism is the term that's come to be used to mean ordin ary members of the public buying tickets to travel to space and back. Many people find this idea futuristic. But over the past few years a growing volume of professional work has been done on the subject, and it's now clear that setting up commercial space tourism services is a realistic target for business today.(Virgin Galactic Website. 2008)The first steps will just be short sub-orbital flights, like Alan Sheppard made in 1961, since these are easier than getting to orbit. But the technical know-how to make passenger launch vehicles and orbiting hotel accommodation is available, and there is enormous unsatisfied demand market research has revealed that most people, at least in the industrialized countries, would like to take a trip to space if it was possible. This gives huge scope for reducing the cost of space travel by large-scale operation like airlines. (Boyle, 2008)One of the main challenges is merely the conservatism of the space engineering as it is today. Since Sputnik w as launched in 1957 almost all space launches and activities are government related. This race to the space has created many activities that projected an image of space exploration and tourism which almost all people kept thinking about. People like – writers, journalists, politicians, scientists and engineers, and the general public give their own insights to the exploration of space and space tourism.Developing low-cost passenger launch vehicles is not just to create a pastime for the rich. In business, the companies that make big money are the ones that serve big markets. Like tourism on Earth, there will be a small expensive segment for the rich – but the great majority of space tourists will be middle-class customers – the greater majority of us. ( Dignan, 2008)The utilization of the space is endless but it is very much dependent on access. Until admittance will become cheap, we can't make use of the unlimited resources and supplies that are available in sp ace for us to have a solution to the problems of our over populated Earth. When the time comes that access will be cheap, admittance to space will much more be easier. Making space travel cheap will require large turnovers of cash and money. Tourism can generate the large-scale launch activity needed to reduce costs sufficiently to start to use space resources – and so it's one of the most important projects in the world today. ( Dignan, 2008)Commercial space activities today include satellites being used for communications, broadcasting and photography (remote sensing). But these are small businesses – no more than a few $billions per year – that will never need humans in space. So â€Å"commercial space activities† today are not leading towards space tourism. (Virgin Galactic Website. 2008)Moreover, if certain companies and people would want a better space travel and tourism adventure, then we should expect that more technologies and activities related to building space vehicles and other will be put in to place.Some people say â€Å"Developing space tourism is very difficult, so it'll take a long time. Leave it to the government space agencies.† But the agencies already spend $25 billion per year on â€Å"space activities† – and they are not trying to develop launch vehicles that could open space up to the public. Barely 2% of their budgets are used for this purpose – although even just one year of their huge funding would be plenty! (Space.com, 2007)The Space Future is playing a vital part in the development of a more accessible space by collecting all the work needed. This includes technology, logistics and others critical factors for the exploration of space.Stages of Space TourismSimilar to any other business franchise, the moment that space tourism begins it will develop and improve dramatically. Today, we can only think of the different stages of space tourism once it gets started and all.. Begin ning with a small-scale and relatively expensive â€Å"pioneering stage†, the scale of activity will develop and prices will go down as it matures. Finally it will become a mass-market business, like airplanes today. (McKee, 2005)Pioneer StageThe phrase â€Å"space adventure travel† has been recommended by Gordon Woodcock of Boeing and is a convenient one to describe the first phase. Customers will be relatively few – from hundreds per year to thousands per year; prices will be lofty, $50,000 and up; and the service will be nearer to â€Å"adventure travel† than to extravagance hotel-style. Orbital accommodation will be safe but â€Å"spartan†. (Virgin Galactic Website. 2008)Mature StageThis will see demand growing from thousands of passengers per year to hundreds of thousands per year. Tickets to orbit will cost less and flights will depart from many different airports. Orbital facilities will develop from being just clusters of pre-fabricated mod ules to large structures constructed in orbit for hundreds of guests, permitting a range of orbital entertainments. (Virgin Galactic Website. 2008)Mass StageTicket prices will go down to the equivalent of a few $ thousand, and customers will from hundreds of thousands to millions of passengers per year. Apparently unthinkable to most people in the space industry, even 1 million passengers per year is just 8 hours of aviation! And aviation is still growing fast at today's level of 1 billion passengers per year. So there's no reason to suppose that space travel will ever stop growing. There's certainly no limit to the possible destinations. And the access to space resources that low cost launch will bring about will ensure that economic growth needn't end for a few more millennia at least. (Virgin Galactic Website. 2008)Space tourism is a business idea whose time has come in today’s 21st century. Surely it will begin soon and it will grow rapidly and develop progressively. This will now push space related activities in the dawn of the 22nd century.Leading Space Vehicle Technologies and Space Tourism CompaniesVirgin Galactic and SpaceShipTwoVirgin Galactic, one of the leading potential space tourism groups, is planning to have passenger service on its first spaceship, the Scaled Composite SapceShipTwo with the inaugural launch in 2008 and main flights beginning in 2009. The price is initially set at $200,000. Headed by Sir Richard Branson’s Virgin Group  , Virgin Galactic will be the first private space tourism company to regularly send civilians into space, by training them for 3 days before their launch. The SpaceShipTwo  was built as a result of the X Prize  which was won by SpaceShipOne;  both SpaceShipOne and SpaceShipTwo were designed by Burt Rutan. Launches will first occur at the Mojave Spaceport in California and will then be moved to the permanent spaceport in Upham, New Mexico. (Virgin Galactic Website. 2008)The spaceships used wi ll go 360,000  feet (109.73  km, or 68.18  miles) high; this goes beyond the height of 100  km, which is the internationally defined boundary between Earth and space. Space flights will last 2.5 hours, carry 6 passengers, and reach a speed of Mach 3. SpaceShipTwo will not require a space shuttle-like heat shield for atmospheric re-entry as it will not experience the extreme aerodynamic heating experienced during re-entry  at orbital velocities (approximately Mach 22.5 at a typical shuttle altitude of 300  km, or 185  miles). The glider will employ a â€Å"feathering† technique to manage drag during the unpowered descent and landing. SpaceShipTwo will use a single hybrid rocket motor to launch from mid-air after detaching from a mother ship at 50,000  feet, instead of NASA's Space Shuttle's ground-based launch. (Virgin Galactic Website. 2008)Space AdventuresEric Anderson is the president and CEO of Space Adventures. He co-founded Space Adventures in 1998 with s everal other entrepreneurs from the aerospace, adventure travel and entertainment industries and has managed the company over the past several years, selling more than $120M in space tourist flights. He has developed and financed over $500 million (USD) in new projects for Space Adventures, including two global spaceports and the first private voyage to the moon, set to launch in 2009.  (Space Adventures Website, 2008)The company sells a variety of flights such as Zero-Gravity flights, cosmonaut training and actual spaceflights. In May 2001, it sent American businessman Dennis Tito to the International Space Station (ISS) aboard a Soyuz Spacecraft for a reported $20 million payment, making him the first space tourist in history. South African businessman Mark Shuttleworth  did the same in April 2002 becoming the ‘First African in Space'. Gregory Olsen  became the third private citizen to travel to the ISS in October 2005, followed by the first female space tourist, Anous heh Ansari, who completed her 10-day orbital mission in September 2006. Charles Simonyi, an ex-executive at Microsoft who managed the Office product group became the world's fifth space tourist in April 2007. (Space Adventures Website, 2008)The  Explorer space plane, which will be the main space vehicle that will be used by Soace Adventures,   is a suborbital   tourist space plane based on the Space Adventures C-21 design. The plane is being developed by Space Adventures  with the Russian Federal Space Agency  and is designed to carry 5 passengers. It is to be air-launched by carrier aircraft from a Space Adventures spaceport. The spaceport for the Explorer is being developed with Prodea in the United Arab Emirates. (Space Adventures Website, 2008)Technological AdvancementThe key in reducing the cost of space tourism is in development of space is in the development of new space vehicles. The current per pound cost of sending anything to space is simply too astronomical for accessible space tourism purposes. The costs climb even higher when sending humans into orbit. Many visionaries and entrepreneurs have realized this and are now working on new spacecraft for the purpose of space tourism.As mentioned, spacecraft for space tourism should have the goal of being economical and accessible. The Soyuz and the Space Shuttle are neither, being too expensive and needing months of training before a space tourist can climb aboard. Another implied requirement is that the spacecraft is reusable. Both the space shuttle and the Soyuz are not reusable to some degree (the Space Shuttle's fuel tank is destroyed upon take off and must be replaced). Another requirement is that passenger preparation be much reduced. Current space tourists must undergo months of grueling training before being allowed to fly to space. Lastly, with any tourism experience, the craft should provide a comfortable and safe ride for its passengers.Today, the most promising space tourism vehicle has been the prototype SpaceShipOne built by Scaled Composites. SpaceShipOne was the winner of the Ansari X-Prize after it was able to reach an altitude of 100 km twice in a two week period while having the capacity for carrying three people. Clearly these abilities are in line with the objectives of space tourism. SpaceShipOne's flight may not be considered true space flight by some people as it is not able to go into orbit. However at 100km, its passengers will be able to experience weightlessness and will be able to see the curvature of the earth as well as the fading of the atmosphere into the blackness of space.SpaceShipOne was able to do this through its design. Instead of using rockets to lift it to high altitudes, SpaceShipOne was lifted first to a high altitude before any rockets were ignited. A conventional jet-powered craft, WhiteKnight, carries SpaceShipOne to high altitude. At the predetermined altitude, SpaceShipOne breaks off from WhiteKnight and ignites its hybrid r ocket motors to push it to outer space. Upon reentry, SpaceShipOne lands like a conventional plane on a traditional runway. Together with the use of the newest materials and technology,   this â€Å"spaceplane† approach was the key in reducing the development and operational costs for SpaceShipOne. SpaceShipOne has now been retired and work is now.ConclusionSpace Tourism may still be a dream for the majority of us but it is undeniable that huge strides have been made in the past decade to make it possible. The development of space vehicles have lowered the cost for space travel and have accelerated the possibility of private space travel. In the next few years, space travel and space tourism will be one of the ordinary things that any family or any person would go to every holiday or every summer. Just like any other place in the planet, travel time will be much faster compared to early flights and the cost will be leveled off. All of these advancements will be our debt to all visionaries and the engineers who are building future space vehicles for our use.

An Inconvenient Truth: People Who Questioned Al Gore’s Motive Essay

Many people questioned Al Gore’s motives for making the documentary An Inconvenient Truth. They wondered whether he created it because he truly cared about the effects global warming would have on the earth or if he just wanted to make himself seem like a better presidential candidate than his opponents. Throughout the documentary Gore presented many facts and statistics that supported his concern, which created the logos for his argument. He also treated the documentary as more of a lecture or presentation for his audience which gave him the credibility that he needed to create the ethos throughout the film. Finally, he used his own personal experiences to appeal to the audience’s feelings and emotions, creating the pathos. In An Inconvenient Truth, Al Gore wants to reach a large audience, particularly nonscientists, to stress the urgency in responding to global warming. Gore uses multiple examples of logos throughout his documentary when sharing statistics and facts that he came upon. One way he presented these facts was with graphs that showed the increase in temperature over the years due to the carbon dioxide levels in the air. The graphs showed a dramatic increase in the levels from previous years which were frightening to see. Knowing the actual levels and how fast they changed made the audience see how dangerous this problem could become if we keep ignoring the issue of global warming. Another way that Gore portrayed logos was through photos of the earth and how it has changed over the years due to global warming. The photos gave a visual example to the audience of how extreme the effects are.

Free Essays on Saplings in the Storm

â€Å"Saplings in the Storm† In â€Å"Saplings in the Storm,† written by Mary Pipher the issue of teenage girls as they mature from girls to adults is shown to be a very complex transition. This transition does not end once a girl finishes puberty either, it is a lifelong process. Pipher goes on to discuss the different phases in a girl’s life after she has reached puberty and beyond. Pipher points out how in a girl’s younger years, she is curious and anxious to learn about the world. Unfortunately, that all changes once she reaches puberty. She no longer is interested in learning about the wonders of the world. She becomes docile, and keeps her thoughts to herself. Her appearance and boys become a much higher priority than expanding the mind. The adventurous nature is gone, and her existence is only for the pleasure of others. Pipher quotes Diredot in a letter to a friend, â€Å"You all die at 15,† (267). This quote is very powerful and very true. From my own experience, I can attest to this fact. Around the time when I was 15, school was no longer a huge priority for me. Boys, who were never important before, became a huge priority in life. I think this is the problem of many girls that age; the opposite sex becomes a central focus in their life. Because of this, my grades dropped drastically. Before, I had many interests, but when I started focusing on boys, my appearance became very time consuming....

Telling Time Lesson With Worksheets

Telling Time Lesson With Worksheets Children usually learn to tell time by first or second grade. The concept is abstract and takes some fundamental instruction before children can grasp the concept. You can use several worksheets to help children learn how to represent time on a clock and how to decipher the time on analog and digital clocks. The Fundamentals The concept of time may take some time to grasp. But, if you use a methodical approach to explaining how to tell what time it is, your students can pick it up with some practice. 24 Hours in a Day The first thing that will help young students learn about time is if you explain to them that there are 24 hours in a day. Explain that the clock divides the day into two halves of 12 hours each. And, within each hour, there are 60 minutes.   For an example, you can explain how there is an 8 oclock in the morning, like when children are getting ready for school, and an 8 oclock at night, usually associated with bedtime. Show the students what a clock looks like when it is 8 oclock with a plastic clock or another teaching  aid. Ask the children what the clock looks like. Ask them what they notice about the clock.   Hands on a Clock Explain to children that a clock has a face and two main hands. The teacher should demonstrate that the smaller hand represents the hour of the day while the larger hand represents the minutes within that hour. Some students may have already grasped the concept of skip counting by 5s, which should make it easier for children to understand the concept of each number on the clock representing 5-minute increments. Explain how 12 at the top of the clock is both the beginning and end of the hour and how it represents :00. Then, have the class count out the subsequent numbers on the clock, by skip counting by 5s, from 1 through 11. Explain how the smaller hash marks between numbers on the clock are minutes.   Go back to the example of 8 oclock. Explain how oclock means zero minutes or :00. Usually, the best progression for teaching children to tell time is to start in larger increments, like start with children only identifying the hour, then move to the half-hour, then the quarter hour, and then intervals of 5 minutes.   Worksheets for Learning Time Once students understand that the small hour hand represents the 12-hour cycle and the minute hand points to 60 unique minutes around the clock face, they can begin practicing these skills by attempting to tell the time on a variety of clock worksheets. Blank clocks worksheetTelling time to the nearest 5 minutesTelling time to the nearest minuteTwo worksheets for filling in random times:  Worksheet 1  and  worksheet 2Fill in the digital times for analog clocksMiscellaneous time worksheets Other Teaching Aids Engaging multiple senses in learning helps support understanding and providing manipulatives and hands-on experiences enhance  the learning experience. There are many plastic-type clocks that are available to help children learn time concepts. If you cant find mini plastic clocks, have your students make paper clocks using a butterfly clip. When a child has a clock to manipulate, you can then ask them to show you various times. Or you can show them the digital time and ask them to show you what it looks like on an analog clock. Incorporate word problems into the exercises, such as it is now 2 oclock, what time will it be in a half an hour.
