Fire Tornado Project

Fire Tornado Project A fire tornado forms when fire is caught up in a vortex. Fire tornadoes or fire devils occur naturally in some wildfires, but you can make a small scale fire tornado yourself. Heres how: Fire Tornado Materials In order to produce a fire tornado, youll need a source of fire and the ability to create an air vortex or whirlwind. The fire tornado is made by placing a container of fire onto a spinning surface. A cylinder of mesh or screening forces the air into a column to force air into a vortex. lazy susan or table or chair that can rotate freelycontainer of fire (e.g., fireproof bowl containing pieces of sponge sprinkled with lighter fluid or alcohol)cylinder of wire mesh or screen with diameter to fit outside the fire bowl. Make the mesh cylinder by rolling a sheet of metal window screening or chicken wire into a tube. Be sure the tube is wide enough to fit around the container youll be using for fire. Staple the ends of the tube to secure it into a cylindrical shape. Create the Fire Tornado Practice this set-up without igniting the fire to be sure your container wont go spinning off. Its a good idea to secure the bowl and screen tube to the lazy susan with tape or glue so that it wont go flying off when you spin the fire. Its also a good idea to have a fire extinguisher handy, just in case. Set the fireproof bowl in the center of the lazy susan. Secure the bottom so the bowl will remain stable when spun.Place the sponge with lighter fluid into the bowl.Set the metal mesh cylinder around the bowl. See if you can spin the lazy susan without incident. You may need to secure the cylinder.Once you are confident of your set-up, ignite the fire in the bowl and slowly start spinning the lazy susan.

Internal Analysis of Wall-Mart Case Study Example | Topics and Well Written Essays - 1500 words

Internal Analysis of Wall-Mart - Case Study Example The paper also details how Wal-Mart can guard against the internal weaknesses and avoid the external threats. Wal-Mart Stores is the number one retail store in the World in volume. The company has more than 7,250 stores," including about 975 discount stores, 2,800 combination discount and grocery stores (Wal-Mart Supercenters in the US and ASDA in the UK), and 590 warehouse stores (SAM'S CLUB)". (Hoovers. Com) The Company is the number one retail store in Canada and Mexico and owns 95 percent stakes in the largest Japanese retailer SEIYU. The company is operating in most parts of Asia, Europe and South America.

In the area of management Wal-Mart has been a committed entity in respect of its responsibilities towards customers as well as communities. The corporate structure of Wal-Mart has three core values of respect for the individual, service to their customers, and striving for excellence. These values have enabled the company achieve the fete of the largest retailer of the world. The marketing strategy in the form of Every Day Low Price (EDLP) strategy has been found to be successful in enhancing the sales growth. The customer oriented approach is one other core value of the company. With ten different divisions of the company available in one place the customer can have a one stop shopping experience which is one of the core strengths of the company. On the financial aspects the company has shown consistent sales and profitability growth during the past years. The company has all its financial ratios indicating its financial strength. The stock price movements are yet another indication of the financial strength of the company. The company has strong and well oriented distribution networks, well equipped and mechanized distribution centers which provide an efficient supply chain management and enormous economies of scale in the operations of the company. The company employs the latest and most sophisticated information and communication technology which enables the company to operate with a clock like precision. Weaknesses The absence of a proper and formal mission statement is the fundamental weakness of the company. The company's mission statement does not provide the necessary definition of their business and does not also provide the direction for the employees. The company has not recognized diversity in the employment with few females in the top management and few minorities. This is a dent in the corporate image of the company. Non-unionization is another weakness of the company. The employees do not have a forum to raise their concerns and hence the employees lack bargaining power. On the marketing side the company has the biggest weakness of continuous expansion. The company has acquired the hatred of many social organizations in smaller towns across United Stated because of the adverse economic impact the company is creating on smaller towns and the trade within these towns. The major complaint in the operation of the store is the increased average time that an

Law,politics,and constitutional government as the distinguishing Essay

Law,politics,and constitutional government as the distinguishing characteristics of western civilization - Essay Example This important question has been discussed for several centuries. Western Civilization has evolved from the colonial period to the present era of much more equality among nations.How have law, politics, and constitutional government contributed to this evolution?First, we must define our terms. By â€Å"law† we mean the rule of law, a basic principle of Western Civilization. The concept refers to a system of well-established and clear principles and precepts which each nation follows. Laws regulate the conduct of the nation towards its own citizens as well as towards other nations and their citizens. This legal framework has also come to include international law, which governs the broader issues which arise among nations. (Gozzi, Gustavo, History of International Law and Western Civilization, April 20, 2007;.http://ssrn.com/abstract=996239) It is sometimes said that Western Civilization relies on the rule of law rather than the rule of men. Of course, men and women must still administer the laws, but the point is that the laws are to be applied fairly, uniformly, and consistently. One’s station in life, wealth, family background and similar factors should not affect or influence the way one is treated under the law. This approach is a major departure from such past systems as feudalism, where serfs did not have legal rights. Similarly, the system of slavery deprived the slaves of any requirements of fair treatment from their masters; they were essentially property. 2 The rule of law has been said to have begun with the Magna Carta in England, which established limits on the absolute power of the monarchy. It required many centuries for that approach to spread to other Western nations and for it to be enforced impartially. Even today, we have not yet achieved the goal of full equal treatment under the law. The evolution of internal and international law is continuing, and remains a major contributing factor to Western Civilization. Politics must also be defined for purposes of its relationship to Western Civilization. We do not mean the political process itself so much as the concept of each citizen having a voice in his or her government, helping to elect leaders and to vote on important issues affecting each person and the nation itself. In order for this political process to occur, the voice of the people must be heard, both individually and collectively. That collective voice is usually organized into a system of political parties, each of which represents a range of viewpoints. In most cases, that range of viewpoints is considerably narrower within one party than between parties. Thus, members of one party may range from liberal to moderate in their views, while the otghe major party may range from moderate to conservative. While the views of both of these parties may meet in the middle, the range is clearly different between them. For this sort of political process to contribute to Western Civilization, it must be the ruling or guiding method of governance in the nation. Some nations have the 3 appearance or pretense of a democratic political process but not the reality. Instead, a dictator or similar official controls that nation, and the politics are merely used to make the people think that they have a real voice. Nevertheless, Western Civilization seems to be advancing towards more real political systems. Constitutional government is the result of the interaction of the rule of laws, democratic political systems, and the concept that individuals are of equa

Critically evaluate the use of neurofeedback techniques as a mechanism Essay

Critically evaluate the use of neurofeedback techniques as a mechanism for enhancing human performance - Essay Example The report also differentiates neurofeedback from other therapeutic treatments used in training the human brain to regulate various cortical activities of their bodies (LaVaque, 2003). Finally, the report pinpoints the numerous criticisms that have been levelled against the use of neurofeedback technique and sums it up by a short concluding remark. From the outset, LaVaque (2003) attempted to define Neurofeedback by alluding that it is a form of conditioning technique aimed at bringing gradual change to the human mind. Broadly, the technique has been associated with Biofeedback which on one hand is claimed to be fundamentally concerned with improving the inherent communication between the mind and the body (Linden & Moseley, 2006). This claim is further confirmed by the definition arrived at by three professional Biofeedback organizations sometime in 2008 where they noted: â€Å"Biofeedback is a process that enables an individual to learn how to change physiological activity for the purposes of improving health and performance. By use of precise instruments to measure physiological activity such as brainwaves, heart function, breathing, muscle activity, and skin temperature, accurate information is rapidly relayed back to the user for eventual implementation†. ... For the foregoing definitions, it becomes critical to address the pertinent issues associated with Neurofeedback techniques. Background Research has variously identified Neurofeedback as a somewhat complicated form of biofeedback that requires sufferers to learn self-regulating certain aspects of their body activities through conditioning. Such distinct parameters of these body activities have been cited by Bladin (2006) as coherence in their mind processes that can be studied using a painless technique namely electroencephalography (EEG). As noted by Nestoriuc et al (2008), Biofeedback has been used in relieving headaches, asthma and blood pressure as well as optimizing performance in elite athletes for close to forty years. The practice has continued to date where Neurofeedback is actively being applied as a therapeutic tool to treat different types of disorders including but not limited to epilepsy, lack of sleep or reduced alertness in children (Norbert, 2007). Further observatio ns by Mark & Barlow (2009) indicate that the advancement in IT has enabled partially incapacitated patients to converse and even show some signs of mobility. Additionally, application of technological prowess has greatly seen Neurofeedback allowing otherwise incapacitated patients learn to normalize physiological processes such as muscle co-ordination, respiration, and blood pressure. This breakthrough is further evidenced by the development of â€Å"Inner Act’s platform for Biofeedback† which is lauded by Cannon et al (2008) as the mostly utilized platform for elite athletes. It is therefore in the interest of this report to mention that most recent researches have focused on the possibility of using healthy individuals as control subjects to prove the efficacy of

Land Desertification in China ( only climatic factor) Essay

Land Desertification in China ( only climatic factor) - Essay Example So China’s arid climate through its consequences of overflows and droughts constitutes a menace to the full-fledged life support of the Chinese and their future generations. In this regard one of the primary concerns is the functioning of the appropriate technologies aiming at recovery of the degraded soils. In the point of the discussed theme there are two key terms, namely: degradation and desertification. Degradation is the steady deterioration of soil characteristics as a habitat of biota, and reduction of its fertility as a result of the influence of natural or anthropogenic factors. Desertification is a process of irreversible changes in soil and vegetation, and reduction of biological productivity, which in extreme cases can lead to the complete destruction of the biospheric potential and turning of the territory into desert. The primary concern of desertification in China is a food crisis, as the issue is the main cause of aggrieving the country’s stores of wheat and rice, which form the basis of China’s agriculture. â€Å"According to a general survey of the country, the total area of †¦ regions vulnerable to desertification has reached †¦ 34.6 percent of the entire territory† (Longjun). In the context of the most grounds intended for sowing of the seeds, the percentage of the lands under desertification is critical. Moreover, it rises with the demographic problem of China or the top-priority challenge for survival of the Chinese. Overpopulation of the country is a well-known issue, and desertification in this respect is extremely hazardous for the great number of people whose needs don’t decrease with the degradation of soils. As for the secondary concern of the issue, it deals with the dwindling water supply as well as groundwater decrement. It goes without question that the consumption of water for China’s agricultural needs, human wants, and for the artificial irrigation of the arid lands substantially wreaks havoc on the

RESTful Web Services as an Alternative to Big Web Services Essay

RESTful Web Services as an Alternative to Big Web Services - Essay Example This paper will critically analyse the RESTful web services and the way these web services differ from Big Web Service techniques. RESTful web services The term ‘representational state transfer’ was coined by Roy Fielding in 2000 in his doctoral research paper. REST can be simply defined as software architecture designed for systems like World Wide Web. â€Å"REST is a particular style of enabling communication based on the principle that all data as well as operations on data are enabled using strictly static URLs based on the HTTP protocol† (Kashyap et al, 2008, p.207). This architectural model has been developed over the recent years as a widely accepted web service design model. REST has a specific set of architectural principles that assists a user to design customized web services focusing on the resources of a system. As Rodriquez (2008) points out, this model’s simplicity has assisted it to displace interface designs based on WSDL and SOAP over the last few years. Even though this software architecture did not gain much attention during its initial stages, today it is being quickly developed to support web based services. The REST architectural design specifically defines six constraints that have been applied to this software architecture. ... Similarly, servers do not focus on user interface so that they can be more scalable and simpler. Stateless The communication between the client and the server is further constrained since client contexts are not saved on the server between service requests. All the essential information required to serve the request will be included in requests by any client. Since the servers can be stateful, they will be more visible for monitoring and more reliable in partial network issues. Cacheable Since clients can store responses, they (responses) must be clearly defined as cacheable or not so to prevent clients from reusing improper data in an attempt to service further requests. Effectively managed caching would eliminate some sorts of interactions between client and the server and contribute to scalability and performance (Bhuvaneswari and Sujatha 2011). Layered system Generally, it is not possible for a client to indicate whether or not it is connected to the end server or an intermediary . Since intermediary servers are able to provide shared caches, and enable load balancing, they can significantly improve system scalability. In addition, such intermediary servers can enforce security policies. Code on demand A client’s functionality can be temporarily extended or customized by servers through transfer of executable code. It is the only optional component of REST software architecture. Compiled components like Java applets and client side scripts like JavaScript are some well known examples (Oracle, n.d). Uniform interface The uniform interface between clients and servers play a notable role in simplifying the architecture. The four guiding principles of uniform interface are â€Å"identification of resources, manipulation of resources through

Comparable Destinations, Different Paths Essay Example | Topics and Well Written Essays - 1500 words

Comparable Destinations, Different Paths - Essay Example The letters also explain why nobody else has been to Utopia. The reason is so ridiculous that it lends believability to the statement--someone had coughed and the exact longitude and latitude had not been heard, but Raphael was being sought to disclose the information. The first book tells of the traveler Raphael Hythlodaeus, to whom More is introduced in Antwerp and also explores the subject of how best to counsel a prince, a popular topic at the time. Plato doubtless did well foresee, unless kings themselves would apply their minds to the study of philosophy, that else they would never thoroughly allow the council of philosophers, being themselves before, even from their tender age, infected and corrupt with perverse and evil opinions (More 8). More tries to persuade Raphael that into the lucrative service of royalty, acting as an advisor to kings or lords. Raphael, however, seems to be saying that his views would not be listened to because such men are too corrupt to understand so pure a study as philosophy. Raphael speaks of Plato, of whom he seems to emulate the thoughts and ideals. The above statement screams of Platonic thought, suggesting that kings must be philosophers as well in order to rule fairly and wisely. More seems to consider it a philosopher's duty to ... While Raphael has chosen to embrace the idea of starting again, the character More desires to fix things as they are. "The difference is only a matter of one syllable," Raphael says as a way to illustrate the short distance from service to servitude (More 7). One syllable indeed. This simple sentence may offer a clue that can answer a question of much debate in regards to More's Utopia. The question is, as a reader, can one accept this imaginary society as a realistic blueprint for a working nation On the other hand, should one assume that More had no intention of his book being taken seriously One could arguably maintain either position. More's Utopia most definitely works if viewed as a satire. By taking into account More's use of these puns, one can deduce that his intention in writing Utopia is to reveal more about the current state of politics in 16th England than it is to offer a model for an ideal society. Support for such an argument can be easily supported by simply looking at the title of the book. The word "Utopia" has two roots. However, depending on which root is chosen, the meaning of the word changes drastically. "Utopia" is a combination of the syllable eu, which can be translated as "good," and the word topos, which means "place." At the same time, if one assumes that the ou prefix is used, which has a negating tone and translates into "no," then suddenly More's "good place" becomes "no place." The difference is only a matter of one syllable. More's hints at absurdity extend beyond simply the use of pun in the title/name of the island, being found in even his description of the island of Utopia. According to the
