Introduce what the Hurricane is to element school students Essay

Introduce what the Hurricane is to element school students - Essay Example to 600 miles across and have strong winds spiraling inward and upward at speeds of 75 to 200 mph.† This kind of weather usually enters what is called an Area of Responsibility and lasts sometimes for more than a week because it is passing over the open ocean at the slow speed of 10-20 miles per hour. It usually moves in a counter-clockwise direction over the warm ocean waters in the Northern Hemisphere, but then moves clockwise when it is in the Southern Hemisphere. While the hurricane is passing over the warm water, it starts to gather heat and energy with the help of water evaporation which also increases the power of the storm. Remember our grandparents often telling us that there is a â€Å"lull before the storm†? That is exactly what happens before a hurricane unleashes its deadly winds and water over the population of an area. The â€Å"eye† of the storm is what our grandparents normally describe to us which is known to have light winds and fair weather. But the minute the storm hits land, this calm is replaced by heavy rain, strong winds, and large waves that come crashing onto land. This is what destroys our surroundings. The hurricane, which is known as a typhoon in the Western Pacific, tends to dissipate or disappear by weakening and drying up once it passes over large and long bodies of land. It dies because the storm feeds on warmth and water, without it, the storm will not be able to exist. Not all hurricanes are created equally though. That is why the Saffir Simpson Hurricane Scale helps our weather professionals determine the strength of the hurrican before it hits land. the warnings range from the lowest wind speed of Category 1 all the way to the destructive Category 5 hurricane. However, a hurricane is destructive regardless of the category because the destruction will rely mostly upon the areas hit and what hazards exist in that area (What is a Hurricane?). In the United States, we have what is called a Hurricane Season that lasts from May

Evolution of the Use of Wool Term Paper Example | Topics and Well Written Essays - 1000 words

Evolution of the Use of Wool - Term Paper Example Since then, man has made efforts to improve and maximize on it by selective breeding of excess wool producing sheep and also incorporating other qualities into the wool fabric, including mothproofing, stain-proofing, durable creasing and pleating, shrink resistance and shower-proofing (Guthrie 145). Science and technology came in to improve the quality of wool and maximize the products keeping it in the fabrics forefront making it suitable for the modern requirements without affecting its virtues. After man started domesticating sheep, he used to milk it, and whenever it would shed its fleece, it would be collected, spun, and used to weave clothes. It then dawned on a man that killing sheep for meat only was a waste of resources, material, and food. He then resorted to becoming a shepherd and later on came up with a method of producing clothes from the fleece. He used to spin the wool to produce a thread by taking it in one hand and drawing it out twisting it using the fingers of the other hand. This then resulted in a thick yarn that was uneven. Later on, man developed a crude spindle, where he fitted a clay ring or a stone to a short wooden stick end. The ring made it possible to wound the drawn-out yarn on the spindle. This spinning method was later used for thousands of years. The threads were woven to produce clothes, and the first products were made up of a beam from which warps were hung before being weighted by the stones at the lower end. The yarn was then threaded across the warp in such an act of over and under. This system was also used for thousands of years just like spinning (Gleason 185). After the two implements for spinning and weaving spun wool, the first improvement to be done was on the loom. Instead of the vertical suspension of the warp threads from the beam, they were horizontally laid across the frame. Sticks were then tied to with  alternate warp threads, and they would be lowered and raised in turn.  

War on Terror Facts Essay Example for Free

War on Terror Facts Essay Terrorists, by definition, fight an entirely different type of war. Acts of terrorism are not perpetrated by soldiers, they are carried out by individuals, or groups of individuals, who have no other recourse but to lash out at the nations that they perceive as their oppressors with whatever tools they have available. They strap bombs on their backs, walk into areas crowded with people, and strike a blow for the cause. Car bombs, snipers, hijacked airplanes, it makes no difference how the terrorist act is accomplished, as long as it has the desired effect. There are no rules of warfare, no governments to be held accountable, and no moral standards to be upheld. Now we find ourselves, as Americans, waging war against an army of individuals that have no common country, government, or ethical measure to which they can be held accountable. Their numbers increase exponentially as we drop smart bombs, and roll tanks over the very people that the terrorists fight to liberate from oppression, further fueling the fire of hatred that burns for us and what we stand for. Whether the U. S. s seen as a liberator, freeing the people from oppressive Fundamentalists, or the Fundamentalists are seen as Freedom Fighters liberating the people from an occupying force, the reason for the conflict is irrelevant. This article is meant only to bring about discussion as to how to end it. The fact is that we are currently fighting a war under terms in which we cannot possibly win, our enemies know it, and they are emboldened by it. Since the beginning of America’s War on Global Terrorism, the number of terrorists in has increased, as have the bombings and casualties, and not just in Iraq. The increase of terrorist activities has increased worldwide, and despite what our leaders tell us, there is no end in sight. If we continue on this course, we will lose this fight. You can win a war against an opposing country or government, but you can’t win a war against an enemy that has no boundaries, no limits, no leader to concede defeat, or an enemy army that gains 10 new recruits for every casualty inflicted. At least not by using conventional methods and abiding by any type of moral code or rules of warfare. The importance of this cliched expression cannot be underestimated. Victories on the battlefield or in the interrogation rooms are meaningless if terror networks can continue to recruit from a large wellspring of discontented youth. And that is exactly what is happening. The wave of horror and sympathy for the victims that spread across much of the Arab and Muslim world after 11 September has long ago changed to something else. America is seen as having capitalised on those attacks by trying to conquer Muslim countries Afghanistan and Iraq. The war on Saddam was seen by many as an unwarranted attack on a largely defenceless civilian population, already emaciated by 12 years of UN sanctions. Washingtons military and diplomatic support for Israel still the bete noire for most Arabs is undiminished. Unfairly, many young Arabs blame their unemployment and lack of a political voice on a US-Zionist conspiracy aimed at somehow suppressing Muslims. But there is also now a growing conviction that the Bush administration has acquired a taste for regime change and will not stop at Baghdad. Threats to Syria and Iran to change their policies only confirm that view. Against this backdrop it is hardly surprising that the US and its close ally Britain are losing the battle for Arab and Muslim hearts and minds

Development of a GIS Within a Water Company

Development of a GIS Within a Water Company Introduction Geographic information systems (GIS) confirm every day, and with increasing popularity, that they are some essential tools for storing, managing, processing and mapping a large amount of georeferenced data, which related to a database shape a given geographical space. The increasingly widespread use of personal computers, along with a greater choice by software manufacturers allow an item, previously limited to powerful computers, can be treated by a large number of users. Geographic information systems make possible, among other things, the ability to extract different layers of thematic information relating to a particular spatial area, as well as all kinds of analysis and diagnosis in areas as diverse as territorial planning, or the environment or management resources This report aims to examine the development of a geographic information system within an organisation. More specifically it is a water company, as might be the case of Thames Water. This report will go into the operation of a large water company. The nature of the information included into geographic information system is varied. For example, data from network infrastructure projects are used as well as a geographical aspect, such as hydrologic basin boundaries, water bodies and other In this company there is also administrative information such as databases related to public use of water resources in a basin. Another type of information made available is the satellite image. For the development of the geographic information system it has been necessary to carefully define its own infrastructure of all the components involved in the process. These components are: hardware, storage, software, information structure in a server (done in a way that can be cost effective), tools for accessing and updating. Thus, it allows system users to access all information related to use them in tasks of water management. The idea of the implementation of a geographic information system in the company aims to provide technological and methodological solutions to the tasks of water management. The geographic information system is established to respond to questions that are not predefined in advance. Background An initial analysis of the company gives an idea of its size, and in base to this, the kind of infrastructure is chosen. Also, an study of the resources available is needed in order to meet the requirements of GIS that the company has. Services are put in place regarding maintenance of the geo-referenced information: infrastructure maintenance Within a water company, like Thames Water, several activities related to water management are summarised next in order to give examples of need for a GIS. First, there is a need to manage water resources, the public usage of water, water supply infrastructure and reservoirs GIS can help in the creation and implementation of water policies. Carry out the administration of public water usage and manage the use of water. Manage the implementation of works and water infrastructure, coordinate the exploitation and management of works and projects. Manage the recruitment, management and control of the earnings in the company A mobile system that reinforce the departments ability to manage field resources and service orders (Jacobs, D. et al., 2007) GIS sources As mentioned earlier, the company deals with information from different sources, each with its particular characteristics: information from infrastructure projects and other projects and other directly related to the natural environment, information from information systems information from satellite imagery and derived products. Information from infrastructure projects and other projects and other directly related to the natural environment The projects that the company deals with generate a lot of geographic information: major infrastructure projects (for example, water supply), environmental monitoring and planning (like flood zones and evacuation routes map (Mioc, 2008) and reference maps on issues relating directly to the environment (for example maps of rivers or watersheds). Once the company receives the information, the administrator of GIS adds value to information. One example is the case of water supply infrastructure: establishing topology, and enabling queries of what happens at certain point. Information from other systems The GIS of the company uses data from other information systems. The GIS software of the company is linked to external databases. Through database connectivity the company have access to information on Oracle format and Access format that contain administrative information with the records of the actions of the public with water resources (for example consume, discharges, building permits, etc..). It is also linked to other information systems with information directly related to the physical environment (network information system of surface water control) The company databases are based on a relational data model where data is stored in two dimensions tables. In this way theses tables are related and contain records for one entity. The company databases are also based in a georelational model where the tables are linked and contain data like topology, attributes etc. Using SQL language the company can query the data from the database and in this way can generate maps and tables with the information required by the users. The integration between databases and GIS software allows the end user to represent the elements of the database on a map, in that way many layers o different maps can be opened and overlaid and geographical relations between the elements mapped can be checked. The company uses Automated Mapping/Facilities Management AM/FM. With this application the non geographic and the geographic information can be integrated in one. The information of the company database is geocoded with the postcode address of their home. The process to geocode can be tedious, so another company does it. Once the information is geocoded analysis can be undertaken combined with other maps overlaid like a city map for instance. Like this the company can undertake different tasks. Information from satellite images and derived products Another type of information that makes use of GIS is the remote sensing information. Through contracts with other companies water company regularly receives processed images from satellites such as Landsat or SPOT. The images are geometrically and radiometrically corrected, the metadata is completed and is integrated into the GIS. The images are produced as a product of great visual interest. Compositions are created with true colour and false colour, easily accessible guide maps are made for quick access to view the images. This information is also used to track water requirements of crops, monitoring of snow cover and monitoring of water quality along the coast. On products derived from monitoring the area are creating databases, initially simple, storing the information, and are creating management tools to generate reports, graphs and maps to access quickly. On products derived from monitoring the area databases are created, that store the information, and management tools are created to generate reports, graphs and maps to access quickly. Maps can be created using this information of humidity index, cadastral parcels with water content, evapotranspiration, etc.. One of the problems that the company is facing is the lack of knowledge of the resources of remote sensing data. The GIS and Remote Sensing software used have been chosen according to the needs of the company: the key points when deciding which software to use in the company are: which benefits the software offer, the profile of users who will use it is also important, number of licenses needed and the price is also important. The technology is used by the company is ESRI because offers a high performance level in GIS: for example, has the necessary tools for analysis and interfaces hydraulic and hydrologic modelling (very important for a water company) and also offers the possibility of programming highly customized interfaces that are often very friendly welcome by users, but the disadvantage is its high cost that can limit the number of licenses. Hardware For hardware, the company has chosen to use a high-powered server as the company is a large size company and the amount of map information generated is very large. It is very important to choose a high performance hardware because as a large company, the amount of data to be processed is very high. When choosing the hardware is taken into account the time factor as the large amount of data that is received daily makes essential a technology that can provide mid-term capacity. Besides, the hardware has to respond to the addition of new series of maps and the continuing contribution of remote sensing imagery. It is essential to manage the huge volumes of geographical data in a efficient and effective way if the GIS is to be cost justified. Apart from hardware and software the structure of the data is also very important. The access to the information has to be easy to the users and also the maintenance and update. Information must be stored in a way that is structured in a objective way, scalable and easy to add new information. The structure of the data have been created according to the major thematic areas within the company. Here are the big four groups where the data has been divided into: Mapping management: maps and databases that include elements of the territory directly involved in the management, control, planning and land always in relation to the water business. These maps are generated within the company. (watershed, sewage systems, etc.). Thematic Mapping: mapping not linked to the water business, but that is related to environmental issues that the company is related to like natural reserves, Mapping of reference: map collections supplied by the Ordnance Survey (all sort of maps, from topographic to aerial photo rectified Other mapping: maps and databases of a part of the territory administered by the company, this mapping may also come from other entities as a result of specific studies Those who do easier tasks they dont need a full training on GIS and Remote Sensing because probably they are not going to use it, but what it is important is that these users have a personalised training on the task that are going to perform normally. For this reason within the company some personalised training is undertaken. Also step by step manuals describing the processes and above all the GIS office of the company is conducting ongoing advice on issues of GIS and Remote Sensing to the entire company. Conclusions Currently the GIS is an essential tool in the in the day to day in the company. Work of different sorts relating the water is undertaken with GIS. The GIS model of the company has allowed, despite some problems, enhance in each of the workspaces GIS as a tool for management, planning and analysis.

As Gass To Cars :: essays papers

As Gass To Cars As gas to cars, food is human’s source of energy. If there is no food there is no energy,If there is no energy the body cannot work, in other words, dies. But the concept of food has changed throughout history. In fact, the concept of food in one period differs from one place to the other and from one class to another. Food serves from a surviving necessity, to a luxury, to a consolation of the soul. Personally, I think that people today have forgotten about the main function of food, and instead of eating to live they live to eat. A lot of people today say that they only eat to survive. They justify their opinion by saying that they eat when they are hungry and hunger is a signal from the body saying that it is in need of energy. I do not agree with them. For example, I think that people today are answering the call of cravings rather than that of hunger. Also, I think that a lot of people today eat to sooth their souls rather than their bodies. Furthermore, considering what people are putting in their bodies as a source of energy makes you expect a chemical explosion. Firstly, if people were eating to satisfy true hunger, then they would settle with anything that they could put in their mouths and fill their tummies with. But no, today their body is calling for chocolate, yesterday their body was in need of a source of energy imported from China, and who knows what will happen next? Maybe tomorrow their body won’t function with anything less than Italian gas. Secondly, today a lot of people seek comfort in food. When people feel empty inside, they try to fill up that emptiness with food. On a personal level, when I’m feeling down I always think that a chocolate bar or a couple scoops if ice cream would pick me up. When I’m feeling excited or hyper, I look for potato chips or salted crackers. And when I feel tense or under pressure, I feel the need of a combination of both sweets and salties. Thirdly, sometimes you are just shocked at what people eat and the amounts they take. Come on, nobody needs all that energy even if they are going to jog all around the world.

Structures and Maximizing Profits

Market structures play an important role in the economy today. The strategic and profit maximizing concepts are determined by the type of market structure. â€Å"Market structure is best defined as the organizational and other characteristics of a market. † (Riley, 2006) Competitive markets, monopolies, and oligopolies three of the four market structures in the economy. A competitive market or perfect competitive market is a market that has many buyers and sellers that do not influence prices. An example of a competitive market would be the street vendors selling bottled water along the sidewalk of a tourist attracted city.There are likely to be many vendors and buyers alike. Most notably the influence of each vendors input on price is low. The opposite of a competitive market is a monopoly. Monopolies affect the economy with considerable control over supply and price. The definition of monopoly is when the single seller of a product controls its market and does not allow comp etition. Local telephone, cable, and water, which are a natural monopoly, are examples of monopolies. Each of the companies has complete control for the distribution of their products or services in regards to supply and prices.Oligopolies are types of imperfect competition in the market structure. An oligopoly is where only a few sellers offer similar or identical products. Consider watching a basketball game at any level of competition. The athletic wear, footwear, and accessories worn by players are more than likely Nike, Addidas, or Reebok. These companies sell products that are similar and are for the same purpose, yet they are not identical. This type of market structure is also known as monopolistic competition. Oligopolies have considerable control over some of the prices of the products they sell.The characteristic of each market structure are important to understand the role of each structure. The determination of price in terms of maximizing profits is best understood by following the rules of production in a given market. Profit maximizing for a company or firm is utilized by using the company’s profit maximizing output level. This is when the marginal cost is the same as the product price. When a company offers products in new locations the marginal cost of the products of the new locations is a part of the marginal cost. That would be an example of a company opting to profit maximizes their production ased on change of total cost to accomplish more profit. Another consideration of a profit maximizing rule is when marginal cost equals price. A company attempting to profit will manage this rule closely to determine profitability. The average total cost of a good is the deciding factor in profit maximizing where marginal cost equals price and marginal cost increases. Monopolist market companies maximize profits by following the rule marginal revenue equals marginal cost. Marginal revenue is the change in total revenue that results from a chan ge in output.Companies that are the single producer of a product will want to maximize their total revenue. Costs of production are low therefore marginal revenue will equal cost. Competitive markets, monopolies, and oligopolies have profit maximizing rules that compare price to marginal revenue, marginal cost, and average total cost to determine profit gain. Each market consists of barriers of entry. One of the reasons for entry is the encouragement of successful gain of profits from other companies. Consider the local and national fast food hamburger restaurants.McDonalds began as one of the first restaurants of its type followed by chains such as Wendy’s and Burger King. That is an example of monopolist competition at its best. A discouragement or barrier for entry into certain market structures is through law and regulations. Creating anti-trust laws are detrimental to the formation of monopolies and their continued growth. There are three examples of business practices t hat present a dilemma for business entry. Resale price maintenance is the setting of a product price is contracted by the wholesaler for the retailer to sell at that given price.If the price is set from the wholesaler competition is suspended because of the price being uncontrolled by the retailer. The next business practice involves market power. A company that possesses market power has control of setting and changing prices without losing customers or altering the entire market. These companies are also referred to as price setters. â€Å"Firms with market power normally use that power to raise prices above the competition level. † (Mankiw) Predatory pricing is a debatable topic in terms of entry into a market and regulated policies. The third type of a business entry barrier is tying.Tying forces smaller businesses to strategize products based on the market power and price discrimination practices of manufacturers. There are four other barrier entry provisions for various markets. First, there is the denial of entry into a market or the lack of possible competition. Next, a company may own a key resource that provides exclusive rights to that market. Another point is when the government allows a single seller the right to produce or provide certain goods. Finally, the cost of production equals a single producer being more efficient versus the cost of production via a large number of producers.The characteristics, price determinations, and barriers of entry into competitive markets play essential roles in the economy. The characteristic of each market provides buyers and sellers to understand and make business decisions for the success of the economy. The economy as a whole benefits from how market structures abide by the rules and regulations of profit maximizing. References Mankiw, N. G. (2007).
