Plastic Architecture - Building The Biodome

Plastic Architecture - Building The Biodome By definition a biodome is a large controlled internal environment in which plants and animals from much warmer or colder regions than the region of the biodome can be kept in the natural conditions of their own sustainable eco-systems. One example of a biodome would be the Eden Project in the United Kingdom which includes the largest biodome greenhouse in the world. There are three biodomes at the Eden Project: one with a tropical climate, one with a mediterranean, and one that is a local temperate biodome. Large biodomes are architectural wonders, while the designs have much in common and take from the geodesic domes patented by Buckminister Fuller in 1954, there have been more recent innovations in building materials that have made the enormous light-friendly roofs in biodomes and other architectural projects possible. The Eden Projects biodomes are constructed with tubular steel frames with hexagonal external cladding panels made from the thermoplastic ethylene tetrafluoroethylene (ETFE) replacing the use of glass, too heavy a material to use. According to Interface Magazine,ETFE foil is essentially a plastic polymer related to Teflon and is created by taking the polymer resin and extruding it into a thin film. It is largely used as a replacement for glazing due to its high light transmission properties. Transparent windows are created either by inflating two or more layers of foil to form cushions or tensioning into a single skin membrane. Plastic Architecture Lehnert, an avid yachtsman and three-time winner of the Admirals Cup, was researching ETFE for use as a possible material for sails. For that purpose, ETFE was not successful, however Lehnert continued to research the material and developed ETFE-based building materials suitable for roof and cladding solutions. These cladding systems, based on plastic cushions filled with air, have since pushed the boundaries of architecture and allowed the creation of highly innovative structures such as the Eden Project or the Beijing National Aquatics Center in China. Vector Foiltec According to Vector Foiltecs history, Chemically, ETFE is constructed by substituting a fluorine atom in PTFE (Teflon) with an ethylene monomer. This retains some of PTFEs qualities such as its non-stick self cleaning properties, as in non-stick pans, whilst increasing its strength, and in particular, its resistance to tearing. Vector Foiltec invented drop bar welding, and used ETFE to construct a small cable structure, originally made from FEP, which had failed due to the low tear resistance of the material. ETFE provided the perfect substitute, and the Texlon ® cladding system was born. Vector Foiltecs first project was for a zoo. The zoo looked into the possibility to implement a new concept whereby visitors would pass through the zoos in small confined pathways while the animals would be, according to Stefan Lehnert, almost living in broad areasâ€Å"†¦almost in freedom.† The zoo, the Burger ´s Zoo in Arnheim, hence also looked for transparent roofs, which were to cover a large area and at the same time would allow the passage of UV rays. The Burger ´s zoo project eventually became the very first project of the firm in 1982. Stefan Lehnert has been nominated for a 2012 European Inventor Award for his work with ETFE. He has also been called the inventor of the biodome.

Jean Val Jeans Influences †Les Miserbles

Jean Val Jeans Influences – Les Miserbles Free Online Research Papers Jean Val Jean greatly influenced everyone he came across. He influenced Fantine to repent her sins and stop her line of work. He helped her try to get her daughter back and gave her a place to stay and eat even though she had a daughter out of wedlock. In addition, he influenced the prisoners to try to change how they act by telling his real name to save that simple man from death. He influenced them by showing them how he changed his life around. Javert was a coldhearted, unkind, and selfish man and Jean Val Jean influenced him to put his own selfishness aside and forgive people for things they have done in the past if they have changed their way of life. Jean Val Jean influenced Cozzette by taking her in and being kind and gentle towards her. So she grew up to be gentle and kind also and she shows this by her giving food to the poor and being nice to everyone not just people of her social class. He also influenced the republics because Jean Val Jean told them not to give up. At what point he even started helping them in the battle to fight for what they believed and try to make things fair. He influenced the poor to help other people by helping them and giving them food and clothes. He influenced the inspector’s assistant by showing him how helpful and kind he was to anybody and that you can be forgiven. The inspectors assistant showed this by letting Jean Val Jean go and get Cozzette before the inspector arrested him. Jean Val Jean influenced many people. Theses are just a few of those people. He was a forgiving, caring, helpful, unselfish man and his actions showed people to be the same way. His acts of kindness were witnessed by everyone that is why Jean Val Jean was considered such a great man and a great influence on everyone.

Research Methods critique of a qualitative journal Literature review

Research Methods critique of a qualitative journal - Literature review Example It is a concise title, which is free of extraneous words and or phrases. Abstract. The wide ranging approach of the article is confirmed in the abstract which stresses the â€Å"complex and multifaceted† way in which ideology affects people at various stages in their professional careers, and in different contexts. The abstract highlights the theoretical underpinning of the work by the work of Goffman on frame analysis (1974; 1981) and outlines how a grounded theory methodology was used to analyse the interactions between professionals and older people. There was some indication of the scope, the variables and the findings of the study in the abstract, but little in the way of detail. The most accurate description for the type of research that this study represents is a survey, with strong theoretical underpinning and a focus on linking ideology with practice. No direct interactions between social workers and clients were observed, and the information about such interactions w as second-hand via the interviewing process. Introduction The problem that the article addresses is was very clearly defined as a need to evaluate the success of the 1990 NHS and Community Care Act in meeting the needs of older people. This is not a new issue, since the Act had been in force for almost two decades at the the time of publication of the article, but the author demonstrates that the critical literature has produced very mixed evaluations. The complexity of the environment, with its conflicting demands such as professional standards, management directives, shifting ideologies, financial constraints and different individual values has led to a proliferation of research outputs which illuminate the detail, but do not address the more fundamental question of dominant ideologies. The background to the problem is described as â€Å"a practice context that has challenged well established modes of social work intervention, †¦ an emphasis on inter-professional workingâ₠¬ ¦ and ethical considerations surrounding service rationing and individual rights.† (Sullivan, 2009). The problem itself is clearly formulated as a need to â€Å"explore both the manifest content and the functional properties of dominant ideology in community care practice†. (Sullivan, 2009) Literature Review Sullivan cites a number of key studies in her description of the fundamental changes in the delivery of care to older people since 1990. These include the work of Postle (1999; 2000; 2002) on the changing role of social workers, and various studies on how bureaucracy affects the delivery of care, such as Lipsky (1980) in an American context and Ellis et al. (2007) in a UK context. Stereotypes of social worker description are listed with reference to Wilmot (1995) and Dalley (1991). A great many studies on organizational policy and its effects on professionals and older people are cited. The extensive quotation of other scholars gives the literature review the qual ity of a meta-analysis, and at the end of this the author homes in on the issue of how ideologies impact on practice delivery. The somewhat overpowering density of references is no doubt due to the fact that the article rests on the author’s PhD research. (Sullivan, 2003). Method procedure. The study proper begins with a reiteration of Goffman’
