Evolution of building materials Essay Example for Free

Evolution of building materials Essay In chapter 12 we explore the artistic development in Architecture. When conceptualizing a building architects incorporate three things: function, form, and structure. Function is how the building will be used, form is how the building looks, and structures is how the building remains standing. Architects need to design structures that hold up under any combination of three physical forces; compression, tension, and bending. To days architects have a plethora of materials at their isposal, they benefit from the evolution of materials and have the opportunity to use them how they wish, but it has not always been this way. Primitive buildings were built using dry masonry, which is a simple technique of stacking stones in a consistent pattern without using any mortar. Buildings such as the Great Pyramids of Egypt, and the Great Zimbabwe(190) in East Africa are perfect examples of this type of masonry. In both of these structures the stones are dressed meaning they are cut or shaped before use. Post and beam and arch structure systems were used predominately before the wentieth century, in places like Greece, Rome, and Egypt. The form on post-and- beam structures has to due with the materials used. Stone beams have to be shorter and thicker because stone is brittle and not flexible. Wood however is more flexible so they can be thiner and longer in turn they can be use to create a more open interior space. Arch structure uses stone in a semi-circle atop two columns or piers, bigger versions of columns, creating a Round Arch. There is a stone placed center that hold the arch together known as a keystone. When a round arc is extend in a epth dimension, the effect is known as a Barrel Vault. When two Barrel Vaults intersect the point of intersection creates a Groin Vault. These types of structures were used by early civilizations of western Asia and the Mediterranean area for underground drains and tombs. Romans were the first to use the technique aboveground and there were able to use it to build things like the Roman Coliseum and the Pont du Gard(192), the aqueduct, which was both a bridges for travel as well as a bridge for water. When an arch is rotated 180 degrees it forms a dome, that is sed in to create huge interior space. Gothic style architecture introduced a new type of arch, a pointed arch which allowed for wider bases and a more pointed arc, but is uses no keystone. The absence of the keystone creates a weak structure that could not hold up under the tension force. The create the flying buttress, which is a support placed at a 90 degree angle to the arch and holds the structure in place. The next major step in the evolution of Architecture was truss and balloon frame architecture. Trusses are triangular framework use to span air support, such as a russ of house roof, or one used as a side of a bridge. Balloon framing refers to the use the replacement of thick timbers with thin studs held together by only nails, at first though of as flimsy and weak, but is used today in housing development. The evolution ot metals in the architectural world nave been immense. T development of cast iron allowed for buildings to be put up very quickly, because it is stinger that wood or stone and can span greater distances, The Crystal Place was built in only six months and covered 19 acres of land, it was a marvel of the building world. Next Came Steel and reinforced concrete buildings. The strength of steel frames and the recent invention of the elevator allowed for the first conceptualized and built skyscrapers. This resulted in the International Style meaning the use of modern material like glass, steel, and concrete to create these types of structures. Domino Construction System, were six supports made of steel are placed in concrete slabs, alleviates the need for support walls, opening the door to building for rooms for how they need to be used, and the ability to make walls almost completely out of lass known as curtain walls. Carbon fiber is the latest material to surface, not yet used for building, it is extremely light, and very strong. Architects are now conceptualizing how they might be able to use this material in the future. Carbon fiber has the potential to revolutionize the building world. Many building now days are trying to reach a harmony with nature in both design and energy efficiency. Buildings like Guggenheim Museum Bilbao(200) are putting in to practice the ever changing face of nature in the design of the buildings. Green uildings are springing up everywhere either new construction or renovating existing buildings to make them energy efficient and revolutionary at the same time. They evolution of building materials and design allow for architects of today the opportunity to implement beauty in their designs. The ability to incorporate any material from stone steel and glass concrete and wood into a building has resulted in some of the worlds most beautiful and elegant structures dating back to completely stone building, to todays hi rise structures, architecture is a beautiful thing.

Barbara Ehrenreichs The Hearts of Men Essay -- Barbara Ehrenrech Gend

Barbara Ehrenreich's The Hearts of Men Barbara Ehrenreich, in The Hearts Of Men, illustrates how gender roles have highly constricted men, not just women, and therefore have inhibited American society from developing its full potential. She deviates from conventional wisdom, which says that gender roles have been largely detrimental to only half the population, which is simultaneously confined to working in the domestic sphere and prevented from participating in the public realm. Her theory says that Americans subscribe to a "sexuo-economic system" which reduces men to "mere earning mechanisms" and forces women to "become parasitic wives" (6, 4). As she explains, members of both sexes adhere to a system which forces them to succumb to specific gender roles, which in turn prevent them from becoming their true selves. Thus, every American has a vested interest in restructuring the ways men and women interact. The most striking element of Ehrenreich 's argument, however, lies in the her assertion that men have suffered more than women from their gender role. This provides a compelling incentive for the American patriarchal power structure to want an end to stifling gender roles. The power of her argument comes from the union that would occur, if men agreed a change must be made with women who have felt this way for centuries. Ehrenreich hopes that men and women "might meet as rebels-not against each other but against a social order that condemns so many of us to degrading or meaningless work in return for a glimpse of commodified pleasures" (182). The most illuminating element of The Hearts of Men is the unique approach Ehrenreich takes in evaluating the effect gender roles have on men financially. She takes the fact that ... ...ts Amendment it was women who voice the loudest protest. For anti-ERA women like Phyllis Schlafly, "the interests of the sexes are irreconcilably opposed; the survival of women depends on the subjugation of men; the most intimate relationships can be used as instruments of a larger coercive scheme" (168). Ehrenreich looks at the issue of gender equality from a unique, untraditional perspective. Instead of focusing on female benefits, The Hearts of Men demonstrates how much men stand to gain through gender equality. "Men will have to give up ruling-class privileges, but in return they will no longer be the only ones to support the family, get drafted, or bear the strain of power and responsibility" (116). An article was written in Time in 1970, entitled "What would it be like if women won?" Ehrenreich book "strongly suggests in would be like men had won too" (116).

Crime and crime prevention

With the economic climate in the state that it's in, unemployment levels are extremely mean people are struggling to afford the exceedingly high cost of living resulting in the increase of crime rates throughout the country. Thanks to this crime prevention methods have been improved by many new technological devices e.g. databases, CCTV, fingerprinting and speed cameras. DNA database The DNA database can help police investigators link individuals to certain crime sense, this can help add to the evidence against a suspect. People leave their finger prints everywhere, therefore this is why the DNA database is one of the most reliable and trust worthy forms of evidence, also this is one of the most commonly used methods throughout the police force. By the use of this technology it has helped many ‘cold cases' be resolved, because this technology wasn't available 15 years ago as it's still a relatively new method of gaining evidence. The database has raised many people awareness of the police and made them realise that it might not be as simple as they believed to commit a crime anymore as there are many different and affective ways of finding the ones reasonable. Because the database holds over a million individual fingerprints, this can result in the process being slow as it has to search through each individual file trying to make a confirmed match. Overall the concept of the DNA database with the technology to scan fingerprints into system where they can be matched to previous crimes and individuals is a great asset to the police helping solve many crimes. CCTV Because of the increase in crime and shop lifting within the 20th century along with the new revolutionary technology, most stores have covalence systems fitted. This makes people scared, and they decide that they don't want to steal anything as they know they will get caught. CCTV is an easy way to keep people from stealing things however it is also very useful when it comes to catching people that have committed the crime. Many smaller businesses would have problems affording a full CCTV set up, to buy a full system with 2 cameras not including insulation would set you back anywhere between à ¯Ã‚ ¿Ã‚ ½300 and à ¯Ã‚ ¿Ã‚ ½500. Many people dislike the idea of CCTV cameras watching our every move in town centres and cities; they feel as it's an intrusion to their privacy. According to statistics, the average citizen is caught on CCTV cameras 300 times a day. Since 2002 the use of CCTV has increased and the crime prevention rate been dramatically improved. A report by the House of Commons in July 2010 states ‘The use of closed circuit television cameras for the purposes of tackling crime has greatly increased over the last decade'. With the use of around 4.2million CCTV cameras in the UK the number of crimes has been decreased by 16%. The most affected area by the cameras is public car parks, by introducing the cameras crime rates have decreased by 51%. By having individuals monitoring the CCTV forages constantly, they are able to see whether or not police are needed and can use judgment to see potential trouble before it happens. In my opinion CCTV has changed lives of many people for the better, as just having the CCTV cameras fitted is enough to put many people off from committing crimes. Also people that use private CCTV cameras benefit as they act also as a deterrent, but if a crime is committed there is a much higher chance of catching the people responsible. Speed Cameras Speed cameras are a great way of controlling the speed of traffic and keeping road users safe, if theses speed are not followed correctly by drivers they are at the risk of receiving a punishment ranging from 3 points and à ¯Ã‚ ¿Ã‚ ½60 fine to disqualification to driving and a fine of à ¯Ã‚ ¿Ã‚ ½2,500. There are 8 different types of speed cameras that operate in the UK, 7 of them check you speed against the legal speed and then take a photo of your car so they have you registration details to identify the driver at fault. There is one different type of camera call an average speed camera, this works on a different principle, unlike traditional speed cameras it is no use breaking when you see one and then speeding up, as the name suggests they work out the average speed between 2 points. Speed cameras develop and now they can check whether you're insured, whether you're wearing your seat belt, whether you're too close to the car in front. And all of these things are checked thanks to only one picture being taken. The police work is a lot more effective with the use of all the technology, and it is a lot harder to commit a crime without being caught due to the fact you are almost always been watched and leaving your DNA where ever you go. Thanks to all the above technology everyone's lives are a lot safer.

Generally fatwa means answers of muslim scholars based on their knowledge on the primary source of Islamic law on a particular issue that is raised. Mainly it is to resolve an issue when there is a doubt on Islamic religious practice that is permissible(halal) or forbidden (haram)[1]. Therefore, there are some methods in publishing and binding of the fatwa in Malaysia. Don’t waste time! Our writers will create an original "Methods on How Fatwa" essay for you Create order The gazetted fatwa are to be obeyed and abide by all the Muslims in that state and also the Syariah Court for that state.[2] The first step to be taken, before making a fatwa is to form a Fatwa Committee that is in charge for the making of a fatwa. The fatwa committee stands by Mufti as the Chairman, Deputy Mufti as the State Legal Advisor, two members of the Majlis Agama Islam, an officer from the Jabatan Agama Islam of each state, two to seven people that is fit and are well appointed by the Majlis Agama Islam and lastly an officer from the Mufti Department who perform his task as the secretary of committee. The second step, secretarial duties is the responsibility to handle the call or to invite every member of the council for bermuzakarah. Each of them will be called if there is a new issue that has arisen and will then return to their respective states to take decisions as a result of discussions at national level. The Secretariat is also listed in this organization and it is the responsibility of the Secretariat and International Affairs Division, JAKIM[3]. Before the committee decides on a fatwa the Mufti would be carrying out a research and a paper works to determine the purpose, the bindingness of the fatwa towards Muslims and to make sure that it is not overruling the primary source of Islamic Law that is Al-Quran and Sunnah. In National level, the procedures of making a fatwa is different compare to state level. It involves a fatwa for a nation and the states that are to be placed under the jurisdiction of the national fatwa. In addition, there has been a Kebangssan Fatwa Council to monitor and coordinate the Fatwa Committee states, especially in a big problem or issue involving the question of the country or the faith of Muslims themselves. Among the issues that have been settled or decided is whether lawful or unlawful Amanah Saham Malaysia, holding al-Arqam, the anti hadith and other. The third step, is the consideration of Fatwa Commi ttee on the Fatwa that has been decided. Here each member will use their expertise in finding the answer to the case or issue arising under the laws of productive resources such as the Quran, the Sunnah, consensus, qiyas and ijtihad(personal legal reasoning)[4]. After the consideration of the Fatwa Committee, the Mufti on behalf of the Committee will bring the decide Fatwa to the Majlis Agama of each state to be discussed or debated with each member of the council at the state level. Even though there is a fatwa that was decided by the National Fatwa Committee, but still there is a tendency for each state to amend the text of the fatwa after it was brought back to the states respectively, and are determined by the state fatwa committee respectively. Despite the fatwa made ÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã‚ ¹ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã‚ ¹at the national level is a decision of the majority of the mufti who is a member, but the changes still occur when it is discussed a t the state level even if the fatwa is a majority decision of the mufti. The state that is chosen to do a research on the Fatwa is Selangor[5]. Therefore, after the Majlis had discussed about the Fatwa Majlis Agama Islam have to get the state Sultan royal assent to be gazetted or to be published. In addition, before the royal assent of the Sultan the Conference of Rulers must be agree on the Fatwa that has been proposed by the Mufti. In the state of Kelantan and Johor Bahru the Sultan royal assent is a necessary to be gazetted. However, in the Federal Territories the Mufti can publish the Fatwa in the Government Gazette without the Yang Di-Pertuan Agong royal assent. After the royal assent of the Sultan was given, the Majlis Agama Islam informs the State Government about the Fatwa and the Fatwa will be published in the Government Gazette. The Fatwa published will be binding to the all Muslims in the particular state. Thus, the Fatwa is more binding and persuasive the Muslims i n Selangor. The Enactment states that all Muslims duty is to abide and uphold the Fatwa unless he is permitted by Hukum Syarak to expelled himself from the Fatwa because of his personal observance.[6] Setting fatwa specified in the law that has been decided based on the evidence before it is no longer necessary qatie someone refers fatwa. This is because the law void fatwa clearly determined based on the proposition that qatie more clearly and completely. In addition, the ruling determined only referred to problems that there is no law. This is an effort to take care of issuing fatwas and human betterment that is not too inconvenient. Therefore, the determination of the law to be respected and cared for in order to be a reference to the next generation[7]. Other than that, the Fatwa Committee is expected to follow the tenets of the Syafie School. However if the Committee believes that following the tenets of the Syafie school would lead to a situation repugnant to public in terests, the Fatwa Committee can turn to the tenets of the Hanafi, Maliki or Hanbali schools[8]. In the case of a conflict of fatwa opinions involving two people of mufti or more in the same problem, the committee members will choose a fatwa that was decided by the mufti of the more pious and devout. When the two muftis have similarities in these properties must also follow the fatwa that was decided by the mufti of the more assertive and exercise the care and caution in issuing fatwa. If both are the same curiosity in these matters, then can choose what fatwa to be followed[9]. In another case, when a mufti who follow his fatwa has died, his position will be replaced by another new mufti. When he issued a fatwa new and different turns with the fatwa was made by the previous mufti of the same problem, then the scholars motion has different opinions on the fatwa which should be followed. For those who think the law should follow the ruling made ÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã‚ ¹ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã‚ ¹by the mufti who had died, they reasoned that the law is not void because the deceased was not a fatwa mufti. While that opinion needs to follow the law made ÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã‚ ¹ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â€š ¬Ã‚ ¹by the new mufti argued that there is at that time was more aware of the environment and current needs. This is because the life or death of a mufti is not a major factor either for use or leave the fatwa[10]. Tentative conclusion, we are able to know that the institution of fatwa is an institution that is very useful and indispensable in solving all the problems of society whether it is big or small problems, fatwa institutions will also issue a new law for the problem. Therefore, institutions should always be lifted fatwa country status as an important institution in the country and it also shows the importance of a country with a majority Muslim community to keep sharia law in their lives.
