Theory report-Archtecture History - Essay Example Toward this direction it is supported that urban design ââ¬Ëis geographically limited in terms that it can be applied in ââ¬Ëareas of a limited size, about half a mile (0.8 km) squareââ¬â¢12. It should also be noticed that modern architecture is characterized by a plethora of innovative plans and ideas which all contribute to the development of the specific science throughout the years. As an example we could refer to the case of Archigram which published in 1961 and included a series of architectural plans of very simple form as designed by Cook, Webb and other architects that participated in the whole effort (Design Museum, 2007). Archigram has been a representative sample of modern architectural ideas despite the fact that its application is not achievable. Apart from Archigram, a series of trends have been developed in architecture which was furthermore supported by theories related with the plans involved. In this context, Utopia ââ¬â a term that is used a lot in the description of specific social and cultural conditions ââ¬â has been related with architecture. The plans that were developed under the influence of ââ¬ËUtopianââ¬â¢ city present many simi larities although there are also elements that are unique in each one of these plans. It should be noticed that the application of the theory of ââ¬ËUtopiaââ¬â¢ in architecture is not recent. In fact there are many studies that refer to the particular issue highlighting the importance of ââ¬ËUtopiaââ¬â¢ for the development of ââ¬Ëunrealââ¬â¢ but pleasant conditions of life for citizens around the world. Current paper presents a personal proposal on Courthouse project using the theory of Utopia as developed in the area of architecture. The particular aspects of Utopia are presented in order to understand its application of architecture and its potential use in the future towards the development of viable urban plans. Moreover, a series of architectural plans related with Utopia has been used in order to

Challenges Faced By Healthcare Leaders In Terms Of Decision Making Assignment
Challenges Faced By Healthcare Leaders In Terms Of Decision Making Within the Team Environment - Assignment Example According to the research findings, leadership is the ability to influence other individuals through oneââ¬â¢s actions and behavior. It should be noted that an organization may have different objectives and goals. It is the duty of the organizational leaders to organize oneself and others effectively to achieve the goals and objectives of the organization. In other words, leadership is all about the effective management of organizational resources in order to satisfy the needs of different stakeholders. In the context of the healthcare industry, the role of leadership is to address the needs of the healthcare staff and patients. In order to become a successful leader in the healthcare industry, a person should be able to improve the quality of healthcare provided to patients, develop and implement strategies to motivate healthcare staff, and ensure the healthcare organizations they run are managed well and demonstrate accountability for their use of resources. Healthcare industry consists of many segments such as aged care and disability health services. The needs of the aged and disabled may not be the same as that of other types of patients. For example, aged and disabled people may have lack of mobility and they require the support of others for completing their routine activities. It is necessary for a leader to formulate strategies based on the needs of the patients in order to make sure that all patients are able to receive quality healthcare services. Moreover, the expectations of the people about the health care services are more in the present era because of the rapid developments in medical science. At the same time, many of the modern patients, especially the aged and disabled patients are concerned about the growing hospital expenses even though they like to receive quality healthcare. Since healthcare industry is a profit-making industry, it is the duty of the leaders to make sure that the hospital management receives adequate returns on their i nvestments.

Kingship In Anglo saxon Britain Term Paper Example | Topics and Well Written Essays - 2500 words
Kingship In Anglo saxon Britain - Term Paper Example The kingdoms stood alone for several centuries during which there occurred Christianization of the citizens. Before the 10th century, these kingdoms were rivals as their respective leaders wanted to gain control over other kingdoms. However, it was the threats of possible Viking as well as Danish settlersââ¬â¢ invasion of the island of Britain that saw the unification of the seven kingdoms into one known as England under the hegemony of Wessex between the ninth and tenth centuries. With the unification and the formation of the new kingdom, an English medieval kingship that is still in use to date came into being. This kingship started with Alfred of Wessex and his succession line gave the English state substance2. The kingship acted as the institution, which had the maintenance of social order as its ultimate responsibility. A medieval king, one needed to adopt delicate approaches that aimed to pay attention closely to the sensibilities of the locals in order to attain success. As such, different rulers of England employed codes that have differences and similarities at the same time. These codes have gone a long way in defining the modes of leadership, the direction it takes, as well as the codes and laws o f the generations of administration that followed them. Alfredââ¬â¢s succession was unexpected with him having four older brothers, which meant that he was fifth in line of succession. However, with the deaths of all the older brothers, Alfred took the throne aged 21 at a time when the kingdom of Wessex was in conflict with the Danes and the Vikings as in all kingdoms in the British island at the time. However, his greatest battle was with the Danes with whom he delved into guerilla tactics and finally defeated them. He also resorted to dialogue when he realized that he could not remove the Danes from the island, with a few intermarriages occurring and even resulting in the conversion of the Danish king into

Chemistry Report on Explosives
Chemistry Report on Explosives Chemistry Report on Explosives What is meant byoxidation and show how oxidation reactions are used to cause explosions. Oxidation is the term used for the combinationof a substance with oxygen, or in general any reaction where an atom ormolecule loses electrons. This can be shown as: C(s) + O2 (g)CO (g) S=solid, g=gas Gunpowderor black powder is the oldest explosive we know. It is made up of a mixture ofpotassium nitrate (also known as saltpetre or KNO3), charcoal, andsulfur in different proportions. When gunpowder is manufactured today, it ismade with the ratios 7.5:1.5:1 by mass (2). Bothgunpowder and dynamite have within them substances which are readily availableto oxidation. The oxygen which is used for the oxidation is an intrinsic partof the mixture, and is held within them in the same manner that oxygen isstored in the chemical potassium chlorate. Whengunpowder is ignited, this oxidation is extremely rapid, and a large volume ofgas is produced. The gasses are under extreme pressure, which causesthem to expand rapidly. Heat is produced causing the gas particles toaccelerate, creating even more pressure. If the gas expands faster than thespeed of sound, this creates a shockwave. The pressure produced by the gassesis what causes parts of the bomb (shrapnel) to be propelled far and wide atvery high speeds(1). Thespeed at which something oxidises is dependant on its potential to interactwith oxygen. The greater number of unstable electrons that a molecule or atomhas to lose, the quicker it will be oxidised (3). b)Ã Ã Ã Ã Ã Give an account of thedevelopment of chemical compounds for use in explosives. Describe theadvantages of each new chemical explosive over its predecessors, and describehow the explosives were adapted to make them safer and more effective. (9marks) It is thought that the firstexplosive discovered was black powder, originating in 10th Century China. Itwas used for ceremonial fireworks. In Europe, 1242 saw the formula for blackpowder being published by Roger Bacon. The refinement of the substance closelyfollowed after the gun was invented by Berthold Schwartz in 1300. Around thistime, black powder was being used for removal of rocks, the teqnique was knownas fire setting, but this was replaced with blasting at the beginning of the17th Century. There are records of blasting in America from 1773 (4). The production of black powderwas rapidly increased during the American Revolution. By the turn of thecentury, the commercial production of the explosive had grown from 25 millionto 100 million (2). In 1846, Nitroglycerin wasdiscovered by Ascanio Sobrero. Nitroglycerin plasticizes collodion which is aform of nitrocellulose to form blasting gelatin. This is a very powerfulexplosive. The discovery of this action led to the advancement of ballistite, thefirst double-base propellant and a precursor of cordite. Alfred Nobel built a factory toproduce it in 1861 in Sweden. An advantage of nitroglycerin was its massiveexplosive power, but it was very difficult to transport as it is a liquid,which used black powder to ignite it. It could also freeze and had toxic fumeswhich caused severe headaches (5). In 1867, Nobel accidentallyinvented Dynamite and he went on to patent his mixture. It was a greatdiscovery, being more powerful than black powder, with a higher detonationvelocity which made it much more effective breaking rock as it not only moved,but broke apart the rock Ammonium nitrate was initially synthesizedin 1659 by J. R. Glauber by blending ammonium carbonate and nitric acid. It wasmostly used for fertilizer and blasting and to replace a portion ofnitroglycerin in dynamite (1). Dupont introduced Nitramon in1935. This was seen as a breakthrough. They had safe handling, were inexpensiveand did not cause health problems. It was known as ANFO (AmmoniumNitrate Fuel Oil) when it was developed in 1955. During its production itcaused a large Texas City explosion. It was easy to load and transport andcheaper than dynamite, it is not a Class A explosive until mixed, but itsaction could be decreased by water. Over 2.2 billion pounds of it were producedin 1974. Water gels were developed from researchto solve the water problem with ammonium nitrate products (early 1940s). Themarket was small though as most applications needed a small product and therewas no economical sensitizer was not available. c)Ã Ã Ã Ã Ã Discuss, with reference to highand low explosives, the ideal features of an explosive reaction, explaining,with examples, how chemical reactions produce energy and how they causeincrease in pressure. (6 marks) There are three categories of explosives: high explosives,primary explosives and low explosives. Gunpowder is a low explosive so thereaction occurs slowly. Expanding gasses are used to propel, not destroy, suchas bullet propulsion from a gun (3). In high explosives, destruction is caused by the expandinggasses, and the extreme pressure causes a shockwave, if the gas expands morequickly than the speed of sound. The shockwave contributes to the demolitionpower of trinitrotoluene (TNT). Primary explosives are intended to explode not burn. Theyare used for fuses and blasting caps to initiate an explosion. Shockwaves are acrucial factor in explosions. It is a wave formed from a zone of enormously highpressure in a fluid, including the atmosphere that travels faster than the speedof sound. It moves from the point of the explosion carrying energy and has a severedamaging effect on solid objects it bounces off (5). In the chemical reaction of the explosion, compounds are brokendown to form various gases. The original chemical compounds (reactants) have muchenergy stored up as chemical bonds between atoms.When molecules break apart, the products (gases) may use some of this energy toform new bonds. Most leftover energy takes the form of extremeheat. d) Describehow UK methods of manufacture of propanone have changed since the beginning ofthe First World War. (3 marks) Propanone isalso known as Acetone, 2-propanone, methyl ketone and dimethyl ketone. It hasthe chemical formula: (CH3)2C=O. Prior to theFirst World War, it was manufactured by hydration of propene from crackedgases. This was revolutionized during WW1 when the chemist Chaim Weizmann showed that propanone could beproduced by the bacterium Clostridium acetobutylicum, this was acontinuation of the studies originally performed by Louis Pasteur showingfermentation was promoted by microbes in the 19th century (2). e) Discuss how attitudes to health and safety in chemicalresearch and industrial chemistry have changed over time. Use examples from thehistory of the development and manufacture of explosives and medicines.(4marks) In modern times, we have a numberof health and safety legislations which govern the manufacturing and use ofexplosives for their various purposes. One example is the 1996 USA Departmentof Commerce directive on the manufacturing of fireworks and explosives (6).There are now very tight regulations ensuring that everyone working in thesector is protected as far as possible. It is also accepted that the companiesinvolved have responsibility to protect their workers from harm and mustprovide safety equipment (3). Historically there have been huge numbers of accidentsduring explosive production. At one gunpowder mill in the early 19thcentury, situated in Roslin, Scotland, explosions killed two men shortly afterthe mill opened in 1805 and three more were killed by 1815. Many more followed.Deaths caused during the manufacturing process would have numbered greatly asthis was just from one of the thousands of mills worldwide during a shortperiod. Old attitudes focused on worker responsibility, were nowresponsibility should be shouldered by the company also. Conclusion Explosions are due to combustionwhich involves the use of the oxidation process. Depending on how available thesubstance is to interact with oxygen will depend on how quickly it is oxidised.The more quickly it is oxidised, the more quickly the gases will expand and themore devastating the explosion will be.

Edna Pontellierââ¬â¢s Broken Wings in Kate Chopins The Awakening :: Chopin Awakening Essays
Broken Wings in The Awakeningà à à Between the caged parrot with a huge cage ââ¬Å"outside the doorâ⬠that repeated ââ¬Å"Get away! Get away! Damnation!â⬠and Mr. Pontellier ââ¬Ës rebuke to his wife that she was ââ¬Å"burnt beyond recognition,â⬠and the description of him looking at his wife as ââ¬Å"a valuable piece of personal property which has suffered some damage.â⬠the antenna went up. There is not a welcoming beckon in the very beginning and we are alerted to the dysfunction of a marriage all with a page or two. It is a sad beginning. The introduction of Robert Lebrun along with Edna sets up the triangle. We are told that ââ¬Å"Robert talked a good deal about himself. He was very young, and did not know any better. Mrs. Pontellier talked a little more about herself for the same reason. Each was interested in what the other said.â⬠Robert from the onset has ââ¬Å"plansâ⬠although he and Edna talk she has none. When Mr. Pontellier returns from Klein's hotel and awakens Edna, with criticism about her care of the children , after a night out with the boys. We begin to see him as thoughtless and as eligible as Edna for the same criticism. She goes into the adjoining bedroom and cries. This indifference on the part of her husband triggers, ââ¬Å"An indescribable oppression, which seemed to generate in some unfamiliar part of her consciousness, filled her whole being with a vague anguish.â⬠At this point the antenna were up and the story began to accelerate. We are told that Mrs. Pontellier was not a ââ¬Å"mother womanâ⬠. The mother women in the story are easy to know ââ¬Å"they (were) fluttering about with extended, protecting wings when any harm, real or imaginary, threatened their precious brood.â⬠They grew wings as ââ¬Å"ministering angelsâ⬠. I noticed along with the caged birds in the opening of the story the number of bird images throughout. It is Mademoiselle Reisz that tells Edna, ââ¬Å"The bird that would soar above the level plain of tradition and prejudice must have strong wings. It is a sad spectacle to see the weaklings bruised, exhausted, fluttering back to earth.ââ¬â¢Ã¢â¬ Edna refers to her new home as ââ¬Å"the pigeon-houseâ⬠. It pleased her. ââ¬Å"It at once assumed the intimate character of a home, while she herself invested it with charm which it reflected like a warm glow.
