Gay Marriage: Social Calamity or Long Overdue? Essay

Abstract There is growing attention to the issue of marriage equality for gay people in this country. As of the writing of this paper, 16 of the 50 states in the United States of America have legalized gay marriage, either by legislation or by popular vote (Wisniewski, 2013). The discourse regarding the issue becomes quite contentious largely because of non-secular ideology that has demonized the concept of homosexuality for many years. As a sociological issue, the conflict has become a divisive force for many, from political powers as far down to the family level. The constitution guarantees equal rights for all in this country; freedom of religion, speech, etc. yet appears to stall when equal rights for the gay community are involved. There has been significantly more popular support for the cause recently, but the stigma and prejudice continue to linger. Is this a moral debate or has an outdated ideology become so embraced by many that the battle has only just begun? Are Rights Really Equal? When asked if one believes in equal rights for all citizens, the typical, rote response is a resounding â€Å"Yes†. If the question becomes more specific as to include the right for homosexuals to marry, a hesitation follows. The concept of gay marriage is far deeper a societal problem for most because its roots lie in prejudicial perspectives that have permeated us for years. Before the fight for the right to marry, the gay community has long endured simply the right to exist openly without feeling pariah-like. The United States is not a theocracy, of this we are certain. However, there are many more religiously affiliated citizens than not. The First Amendment gives us freedom of religion, which should also include freedom from religion. The truth of the matter meets somewhere in between the two, especially when US currency bears â€Å"In God We Trust† boldly on its face. There are political leaders who continue to evoke the name of God in their speeches, even though  the fact is that our founding fathers were mostly non-theists and the motto on our money did not initiate until 1958 or so. But people continue to view homosexuality as a â€Å"sin†, therefore gay marriage is not an option. This issue has created a divide in this country, much like most other civil rights have. When slavery was abolished, it took years to establish anti-segregation laws. Civil change takes time, historically, and gay marriage is no different. Protests continue either in support of or against gay marriage, at times becoming violent. Families become divided when a member openly announces his or her orientation and disapproval prevails, sometimes resulting in families disowning or ostracizing that offender from the family. Government has been forced to become involved, due to an outcry for the various rights that are bestowed upon a married member of this society. Rights to inheritance and to personal medical information and decision making are two examples of spousal rights. Monogamous homosexual couples are denied these rights, since without marriage, the rights fall to their closest relative. Functional Sociology and Gay Marriage Society has long viewed traditional marriage a fundamental and necessary building block. Marriage is the institution by which our population is regenerated and offspring are socialized then integrated as functioning members. Functional theorists might argue that if the paradigm is changed to include same sex couples, social decay may follow, as the family unit is unable to function if not in the traditional way. Single parent households have been faulted with producing children that score lower in school than those from the traditional, two parent family, as well as have higher rates of unacceptable social behavior, such as drug abuse or teenage pregnancy. Functionalists believe children benefit from each gender parent in a different way, therefore require both to be whole. (Tischler, 2011) Conflict Theory and Gay Marriage Conflict theory maintains that society functions when a more powerful or accepted sector exerts its will and exceeds at the expense of less powerful or accepted portions. (Tischler, 2011). Since homosexuality has been regarded taboo by the majority for so long, heterosexuals have maintained their position of acceptance and normalcy in the US. Vocational positions,  especially powerful ones such as political leaders, have historically been heterosexual. We have a â€Å"President† and a â€Å"First Lady†; expected heterosexuality. For the stigma to be removed, traditionally expected and understood ways of life would drastically change. Would traditional, heterosexual marriage decay in the process? The Future of Marriage Regardless of sociological theory, religious belief, and cultural expectation, the movement towards acceptance of gay marriage is gaining momentum and losing the attached stigma. Gay marriage is legal in 16 states (Wisniewski, 2013), and gay couples right to adoption has increased. Heterosexual divorce rates remain hovering at a 50% mark, and have been for many years prior to homosexual marriage. Society is resilient, proving itself over years of change. The ideal aspiration would be for both homosexual and heterosexual married couples to simply co-exist; neither having any real influence over the others’ success or demise. References Tischler, H.L.

Residual Stress

INFLUENCE OF RESIDUAL STRESSES ON FATIGUE FAILURE OF BUTT WELDED STAINLESS STEEL PIPE Areef A Department of Mechanical Engineering Chendhuran college of Engineering and technology Pudhukkottai, Tamilnadu [email  protected] com Abstract— This project is aimed to understand the influence of residual stresses on the fatigue failure of butt welded stainless steel pipe joints. In order to carry out this study it requires an experimental fatigue failure data and a computer aided analysis of these results. A finite element scheme will be developed to simulate the residual stress in weld using the experimental data.A Thermo-elasto-plastic analysis will be used to replicate the butt welded pipe joint and the residual stress will be determined. Residual stress that arises in welded joints by heating and cooling cycles during the welding process is another major factor in fatigue failure of welded structures. Welding residual stresses might lead to a drastic reduction in the fatigue st rength of welded elements. In multi cycle fatigue (N > 106 cycles), the effect of residual stresses can be comparable to the effect of stress concentration.The effect of residual stresses on the fatigue life of welded elements are significant as regards relieving harmful tensile residual stresses and introducing beneficial compressive residual stresses in the weld toe zones. The fatigue failure can be classified in to two categories based on the number of cycles taken to fail. A. High cycle fatigue High-cycle fatigue is when the number of cycles to failure is large, typically when the number of cycles to failure, Nf is greater than 103. B. Low cycle fatigue Low- cycle fatigue is when the number of cycles to failure is small, typically when the number of cycles to failure, Nf is less than 103.III. RESIDUAL STRESS ON WELD Residual stresses can be defined as the stresses that remain within a material or body after manufacture and material processing in the absence of external forces or thermal gradients. They can also be produced by service loading, leading to inhomogeneous plastic deformation in the part or specimen. Residual stresses can be defined as either macro or micro stresses and both may be present in a component at any one time. They can be classified as: Macro residual stress that develop in the body of a component on a scale larger than the grain size of the material.Micro residual stresses that vary on the scale of an individual grain. I. INTRODUCTION Welding has a number of detrimental effects on the structural integrity and in-service performance of the weldments. These detrimental effects are due to imperfections induced by the welding in the weldments, of which the structural shape change behavior, residual stresses and the weld solidification cracks are reported to have very severe degrading effects on the mechanical strengths and possibly can lead to catastrophic failure.Fatigue is a type of fracture that occurs in welds that are subjected to c hanging or varying stresses over time. Fatigue is mainly caused by the environment in which the welded joints are utilized. Fatigue fracture is a ductile fracture, and therefore occurs by non-uniform plastic deformation. Micro cracks and voids form after a certain number of cycles and grow proportional to the number of cycles eventually grow large enough to overcome recovery mechanisms and move quickly to fracture. The rate of this crack nucleation is proportional to the frequency of the applied stress.II. FACTORS IN FATIGUE FAILURES Fatigue failures of welded joint are initiated by many factors, such as stress concentration, environment, loading and residual stresses. Stress concentration is mainly caused by the geometrical discontinuity and thus initiates fatigue crack at the locations of discontinuity. Stress concentration may also result from weld defects and metallurgical discontinuity. Fatigue strength of weld component may also be significantly affected by the environment, su ch as oxygen, sulfur, and temperature.In addition to the axial stresses in the piping systems reduction in fatigue life also takes place by multiaxiality of loading or stresses. Micro residual stresses that exist within a grain, essentially as a result of the presence of dislocations and other crystalline defects. IV. CAUSES OF RESIDUAL STRESS Residual stresses are generated during most manufacturing processes involving material deformation, heat treatment, machining or processing operations such as welding, machining, grinding, and rod or wire drawing etc.It is possible to classify the origin of residual stresses in the following way: 1. 2. 3. Differential plastic flow Differential cooling rates Phase transformations with volume changes are one of the main factors leading to the origination and propagation of fatigue cracks in welded elements. The residual stresses in the welded joints are formed as the result of differential contractions which occur as the weld metal solidifies an d cools to ambient temperature. In fact, welding introduces high heat input to the material being welded.As a result of this, non-uniform heat distributions, plastic deformations and phase transformations occur on the material. These changes generate different residual stresses patterns for weld region and in the heat affected zone (HAZ). Residual stresses induced by shrinkage of the molten region are usually tensile. Transformation induced residual stresses will cause more critical phase transformations. When the effect of phase transformations is dominant compressive residual stresses are formed in the transformed areas.Tensile residual stresses are detrimental to the initiation and growth of fatigue cracks. Weld fatigue failure is often particularly sensitive to residual stress due to stress concentrations induced by the weld joint geometry and weld imperfections. Welding residual stress acts as a booster to the fatigue problem. Hence, crack growth rate becomes considerably highe r in the weld vicinity compared to that far from weld. The fatigue failure mechanism in the presence of weld residual stress is not well understood and it is the intent of this project to explore this mechanism.However, to quantify the effects of welding residual stresses in the design stage, one has to numerically simulate its distribution and redistribution and possible relaxation in a structure due to cyclic loading. This requires the need for a robust, reliable and numerically efficient method for modeling residual stresses. Previous studies reveals that depending upon mean stress, stress amplitude, and stress ratio of uni axial cycle stressing and two kinds of failures ratcheting failure and fatigue failure. Figure 3.Explains the variation of ratcheting strain with stress amplitude. In which we shall see that stress increases apparently with the increase in nominal stress amplitude. It implies that the effect of nominal stress amplitude on ratcheting is more significant than me an nominal stress. The variation of mean stress with ratcheting strain is explained in figure 4. In which we shall see that ratcheting strain also has an increasing trend with the mean nominal stress up to a particular limit. V. EXPERIMENTAL TECHNIQUESWelding residual stresses are generated in a structure as a consequence of local plastic deformations introduced by local temperature history consisting of a rapid heating and subsequent cooling phase. During the welding process, the weld area is heated up sharply compare to the surrounding area and fused locally. The material expands as a result of being heated. The heat expansion is restrained by the surrounding cooler area, which gives rise to thermal stresses. The thermal stresses partly exceed the yield limit, which is lowered at elevated temperatures.Consequently, the weld area is plastically hot-compressed. After cooling down too short, too narrow or too small comparing to the surrounding area, it develops tensile residual stres s, while the surrounding areas are subjected to compressive residual stresses to maintain the self-equilibrium The distribution of residual stresses in a welded pipe is more complex, Fig. 1 shows the possible expansion and shrinkage in a butt welded pipe. In this case, shrinkage of the weld in the circumferential direction induces circumferential force, F, shearing force, Q, and bending moments, M, to the pipe.Figure. 2 shows a characteristic residual stress profile on a low carbon steel welded component. Also the distribution of residual stresses in a pipe is affected by many factors such as diameter, wall thickness of the pipe, weld geometry, and welding procedure. From the graphical plot we shall see that the maximum value of the harmful residual stress is about 360 N/mm2 (tensile stress) near the welding line and it decreases to be about 165 N/mm2 at the distance of 80 mm from the welding axis.The minimum residual stress is about 90 N/mm2 near the welding line and it becomes abo ut 60 N/mm2 in compression at the instance of about 60 mm, then it reduces to about 10 N/mm2 in tension at 80 mm distance from the axis. Such high tensile residual stresses are the result of thermoplastic deformations during the welding process and A. Sample Used The material used for the study is stainless steel material of grade SS304. The material is chosen because of its following properties. It has an excellent corrosion resistance in a wide range of atmospheric environments and many corrosive media.Considering its heat resistant property it is not suitable to use in a range of 425-860 °C if subsequent aqueous corrosion resistance is important. This material has excellent weld ability by all standard fusion methods, both with and without filler metals. Welding of 304 can be done with Grade 308 and 308L rods or electrodes (and with their high silicon equivalents). Heavy welded sections in Grade 304 may require post-weld annealing for maximum corrosion resistance. Tensile Stren gth (MPa) min 515 Yield Strength 0. 2% Proof (MPa) min 205 Elongation (% in 50mm) min 40 Rockwell B (HRB) max 92 Brinell (HB) max 201D. Finite element analysis Most of the residual stress studies were conducted based on either axi symmetric or 2D plane assumptions due to the limitations of the finite element codes and computer resources available during the time of the study. Moreover, the thermo-mechanical problem was assumed to be uncoupled where the thermal and mechanical responses were treated separately. Furthermore fatigue failure usually initiate at the stress concentration area and fatigue loading is usually not axi symmetric, and hence a two dimensional model can not simulate the fatigue failure response of weld joints accurately.In order to simulate the fatigue response of welded joints in the presence of residual stresses, it is essential to conduct a three-dimensional analysis. Figure 5. Illustrates the solid and FE model of the specimen RESULT AND DISCUSSION 3D finite e lement fatigue response analyses for a socketwelded joint were performed by using ANSYS. This is needed in order to include the calculated residual stress and strain fields as the initial stresses and strains in the fatigue analysis. A fixed boundary condition at the socket end is imposed.Same finite element mesh and the material model used in the residual stress analysis, are restricted to be used in the fatigue analysis. The following are some of the discussions we found out after the comparative experiments on Fatigue machine and computer aided simulation. High tensile residual stresses, at or above the yield stress level, exist near the weld toe area, especially at the weld start/stop location. The magnitude of the residual stresses reduces quickly as the distance from the weld toe increases. The residual stress distribution does not change much when the slip-on gap in the socket weld joint is reduced to zero.Hence, the increase in fatigue life of socket welds with no slip-on ga p is unrelated to residual stress. The improvement in fatigue life may come from the change in failure mode, which in turn, may be influenced by the change of the external load stress or strain distribution.

Stainless steel welding Methods There are three methods of stainless steel welding which are preferred over the rest.Metal Inert Gas (MIG) welding, Tungsten Inert Gas (TIG) welding, and Shielded Metal Arc Welding (SMAW). Stainless steel welding requires a bit more finesse than welding mild steel or aluminum, because heat is an enemy in this process. Also the fumes made from any of these processes are very harmf ul, and great care must be taken to avoid breathing them. TIG welding utilizes a tungsten welding electrode, a filler metal rod and an inert gas to shield the weld. This welding method requires little or no post-weld finishing. The tungsten tip in the welding torch is touched to the material to be welded.This creates an arc that the welder dips the filler metal rod into and allows it to melt into the welding puddle. The shielding gas prevents contamination from entering the weld and allows the weld to flow out smoothly. Heat is controlled through a foot switch. So the suggested welding method is TIG welding. C. Fatigue test Butt welded piping joints were tested in a cantilever setup. In these test the welded joint to be tested is located near the heavy and stiff support column. The fatigue loading cycle is applied to the other end of the pipe using the actuator of a servo- hydraulic testing machine through a pin end fixture setup.The pin end fixture consists of a self-aligning ball bearing and a pin, which is snugly fitted to the ball bearing and tightly attached to the end fixture. One of the pin end fixtures is tightly screwed to the actuator rod and the other welded to the specimen. [2] [3] [4] [5] [6] D. Akbari, I.

Assignment Essay Essay Sustainable tourism is being able to the deliver positive environmental, social, and economical results with thought to the needs of the visitors, host community and surroundings. Sustainability as defined in the Brundtland commission report it states as â€Å"meeting the needs of the present without compromising the needs of the future generations to meet their needs†. For example, the small business are starting to practices sustainability principles by changing to renewable energy sources, reducing use of paper and recycling more. As a result, the concept of sustainability addresses the aspects of â€Å"triple bottom line† meaning the balance of societies, economy and the environment are described by (Bonevac, 2010). According to the World Tourism Organization, â€Å"sustainable tourism means meeting the needs of the present tourist and host regions while protecting and enhancing the opportunity for the future†. Instead of just being a product, sustainable tourism is a philosophy that underpins all tourism actions (Owens, Is there a Meaningful Definition of Sustainability? , 2003). To all tourism development and management, it is a fundamental concept instead of being an add-on factor. The foremost aim of sustainable tourism is to maintain the economic and social return of tourism development while reducing or justifying the unattractive impacts on the natural, historic, cultural or social environment (Governemnt, 2009). The stated objectives attained by matching the needs of tourists with those of the destination. Sustainable tourism is an industry, which challenges to make a little impact on the environment and the local culture, though helping to produce income, employment and the preservation of local ecology. Hence, responsible tourism is both cost-effectively and culturally responsive, meaning have minimum impact on the environment and culture of the host community (Group, 2007). Scotland Tourism Organization has defined sustainable tourism as â€Å"tourism committed to generating a low impact on the surrounding environment and community by acting responsibly while generating income and employment for the local economy and aiding social cohesion† (Organisation v. s. , 2013). Scotland Sustainable tourism aspires to guarantee that economic development in terms of encouraging experience for each one involved local community, Tourism Companies and visitors. In practice, sustainable tourism means greener transport, given that transport is innermost to tourism; however it also put pressure on our natural resources and contributes to our worldwide environment impacts. Procedures like cheering visitors to utilize communal transport, and advance in cleaner forms of transport will assist in this area (Organisation v. . , 2013). Regular and environmental strains a more even stretch of visitors lessens pressures on the natural and built environment and on communities, and capitalizes on the financial payback. Scotland Tourism Organization modifies its advertising drive to persuade a stretch of visitors throughout the year and around state (Organisation v. s. , 2013). For example, â€Å"surprise yourself†. There is necessary to work with the public, private and independent sectors to determine the environmental and social impacts of tourism. These guarantees that tourism expansion carries a encouraging experience for home people, tourism companies and the tourist themselves (Organisation v. s. , 2013). Green accommodation is one in that all room offers lessens their misuse, energy and water use. The green Tourism Business Scheme persuades businesses to trim down their environmental impacts. The scheme is one of the largest of its land in Europe with over 800 Scottish members (Organisation v. s. , 2013). However, any tourism industry can take advantage from flattering more sustainable through safeguarding the very features on which tourism depends; taking a sustainable move to tourism expansion is the only way to guarantee long-term tourism expansion in the South Pacific (Organisation v. s. , 2013). The success of tourism in any country depends on taking care of the environmental or social impacts of tourism development. The visitors benefit from sustainable move to tourism throughout from enhanced relates with local communities, a tall value tourism experiences and a natural and fabricated environment. Thus, by fetching a sustainable tourism destination will provide the South Pacific Tourism Businesses a cutthroat frame by producing community assistance for tourism; attaining value savings and designing innovative marketing prospect. As the tourism industry develop in as many regions and countries, it generates noteworthy impact on the consumption pattern, natural resources, pollution and social systems (Organisation v. s. , 2013). For the industry to survive as a whole it is vital to understand and interpret the need sustainable and responsible planning and management. To begin with, education and collaborative partnership are approaches that can assist destinations attain more sustainable tourism. The whole idea of sustainability based on the association through environmental, ecologically and socially responsible tourism. Partnerships with local communities through rural community gathering before and during development are needed in order to let alone the frequent divergence between conservation initiatives and traditional resources users (Billington, Carter, & Kayamba, 2008). The departments from the government can collaborate with the resource owners to develops and negotiate over the investment on proposal (English National Park Authorities Association, 2009). For example, the Chumbe Island Coral Park is a good example of collaborate partnership, which was developed to sustain the natural beauty and attractions of the island (English National Park Authorities Association, 2009). Chumbe Island is located in the Indian Ocean channel of the coast of the semi autonomous region of Zanzibar (English National Park Authorities Association, 2009). The person responsible for the project on the natural park at Chumbe Island was (David, 2011). During her work life, (David, 2011) experience the need for the conservation and sustaining of the natural flora and fauna. (David, 2011) developed an innovative approach to protect marine conservation combined with tourism development through the sustainable and multilevel partnership approach to promote successful marine park management, awareness of marine conservation and sustainable tourism management. David, 2011) Develop a small marine park that would help consume a unspoiled coral reef, offer environmental education for both the locals and the foreign visitors and generate management fund through authentic ecotourism. Thus, the need for the park at Chumbe Island arose due to improper aid and the government in the country noted conservation programs. Hence, the collaborative partnership arose to sustain the nature conservation of Tanzania for the future (English National Park Authori ties Association, 2009). Secondly, the partnership approach deals with the local communities because they are the essential people who are the resource owners (Governemnt, 2009). Engaging the local community in the environmental education on sustainability through workshops and seminars will increase their concerns for the global issues such as climate change (Clark, 2013). In addition, collaboration with NGO has to hold workshops with the angler’s, to engage them in sustainable fishing practices and conservation of the resources (David, 2011). Thus, the young and the old generation in the area is to be informed about sustainable fishing practices, laws and regulation regarding fishing practices and marine conservation area and the benefits of marine protected areas (Ki-Hoon & Ball, 2003). All this environmental awareness, education and training initiative with the community are to provide skill development on sustainable tourism (Group, 2007). The scale of growth of the tourism industry In the South Pacific is rapidly and that the environmental and social, economic impacts of it cannot be overlooked (Azam & Sarker, 2011). This has caused the Pacific Region to find ways in which the industries could be made more sustainable. The industry is more sustainable through minimizing resource use and waste production (Othman, 2004). For the sustainability of tourism, water is the major issue for concern. For example, a tourist in a hotels uses on standard one third of more water per day than a local inhabitant uses and put severe restriction on local supply (Othman, 2004). Activities such as golf course, artificial snow ski’ resorts are in demand of water. For small and medium sized business, sustainability thought of an expensive and difficult idea (Billington, Carter, & Kayamba, 2008). Most of the dominating tourism industries in the South Pacific have not actively engaged in government activities that encourages that adoption of sustainability practices (David, 2011). There are a number of barriers identified by the researchers that hinds implementing sustainability practices in South Pacific tourism businesses including the financial crisis for implementation, the labor insecurity of being certified, lack of government and industry support the technical nature of information forums. Hence are a number of actions businesses could undertake to improve environmental performance (Azam & Sarker, 2011). Activities’ relating to efficient resources use and waste management includes minimizing energy consumption, for example using open ventilation instead of air-conditioning and heaters encouraging the use of renewable sources and improved technology also Getting involved in accreditation programs (Owens, Is there a Meaningful Definition of Sustainability? 2003). There is a need to promote and facilitate the reduction, reuse and recycling of materials and water quality including the efficient treatment of sewerage, avoiding discharge into marine and rivers (Organisation, 2005). For example, in Australia the Australian formula 1 ING grand Prix Corporation, which works with environmental packaging and waste recycling partner to minimize the impact of the race on the environment? Billington, Carter, & Kayamba, 2008) Thus, by minimizing waste use, energy use and waste production, businesses can reduce their impact on the environment and achieve cost savings (Ki-Hoon & Ball, 2003). Furthermore, the conserving and giving value to natural and cultural heritage is of critical importance’s, in order to enhance the quality of life of local communities through tourism, and connect the people in is scheduling and management (Organisation, 2005). The growing awareness’s and generating direct and indirect support for conservation is the key role played by the tourism industry (Group, 2007). The generation of economic propensity for the tourism industry is to provide with quality natural and cultural heritage (Azam & Sarker, 2011). This would ensure the long-term competitiveness, viability and the prosperity of tourism enterprises and destinations and the quality of life of local communities and to the visitor experience by providing a safe, satisfying and fulfilling experience to the visitors available to all without discrimination by gender, race, religion, disability or in other ways (Organisation, 2005). Areas that are of importance to tourism natural and cultural includes the natural landscapes quality and variety, man-made cultural landscapes, heritage and historic sites, the flora and fauna diversity, local uniqueness such as art, crafts, cuisine, language events and festivals (Organisation, 2005). Thus, to address these issues listed above relevant action like being more prepared to use the tourism argument as to fund the prevention of nature and culture and to prevent damaging change (Clark, 2013). Also strengthening the relationship between protected area and local tourism interest, within the context of a sustainable tourism strategy and action plan would lead the South Pacific to be more sustainable (Organisation v. s. , 2013). Sustainable development is holistic in nature; therefore, it requires management of policies and coordination of action between sectors (Othman, 2004). To control the impact of tourism initiated by environmental or developmental strategies and policies legislation and regulations are necessary (Governemnt, 2009). Appropriate strategies or sets of policies for specific aspects of tourism were developed. For example, in Bulgaria the separate strategy for ecotourism, which reflects the sustainability principles? (Bonevac, 2010) This initiative can also be taken by the local Ministry of Environment of Tourism to integrate the strategy in terms of regulations (David, 2011). In coordinating and ensuring success of this specific sub-sector, such regulations and legislations can be very helpful. This can be very helpful in demonstrating processes and formulating policies that could be modified more widely in tourism (Ki-Hoon & Ball, 2003). Strategy and policies must be developed and implemented at both local and national level in order to achieve effective result. Most countries in the South Pacific are in the process of decentralizing their political and administrative structures so local decision-making is the vital aspect toward sustainability development (English National Park Authorities Association, 2009). An integrated approach to the development and management of tourism is within local destinations, is recognized as the most successful direction to sustainable tourism (Governemnt, 2009). Thus, it is vital for the national and local strategies to be corresponding but these two variable in tourism strategies vary in terms of national tourism strategies relates to the national tourism vision of the overall position and direction (Organisation v. s. , 2013). While local tourism strategies relates to the holistic of the local destinations in areas such as local objectives and priorities, local resource opportunity and constraints and many more (David, 2011). Hence, the identifying of policies and instruments to create the enabling environment for sustainable tourism is more of national strategy while the determining of what happens on ground is more of local strategies (Governemnt, 2009). Both the national and local tourism strategies are required for sustainable tourism to embrace the principles of sustainable development and both strategies are reliable and commonly reinforcing (Othman, 2004). Finally, the command control instrument allows government to exert strict control over certain aspects of development and operation, backed by legislation (Organisation, 2005). Legislation, regulation and licensing are the interdependent tools that can be used to strengthen sustainability by setting out requirements that are compulsory and enforceable and which lead to sanctions and penalties if they not met (Billington, Carter, & Kayamba, 2008). The process of checking and signaling compliance with regulations or otherwise identified obligatory standards; assigning permission to operate is called licensing (Organisation, 2005). To control aspects of business development and operations and to influence people’s behavior government are in a position to apply laws, regulations and penalties. These legislation and regulations must be applied when the governments believes that it is necessary to do so (Governemnt, 2009). Thus, for regulations to be successful, it has to be relevant, clear, practicable in terms of compliance and capable of being enforced. In order the tourism industry to be more sustainable the laws and legislations should enable and support the sustainability of tourism and give authority to act (Billington, Carter, & Kayamba, 2008). It should also seek to raise sustainability performance above such standards through other means, which would also stimulate personal commitment towards continual improvement. For example, in the government of Fiji builds up a (EIA) environmental Impact Assessment regulation, which stated that for any company or hotel with an EIA reports in Fiji, has to provide the Fiji Government with an EIA report of the development to progress (Turnbull, 2003). There are a number of areas in which laws and regulations can be implemented to attain more sustainable tourism industry and that includes operation, management and development which are controlled by this legislation to protect the environment, communities, culture and heritage, visitor experience and the business as a whole (Turnbull, 2003). The purpose of government intervention in the sector as law provides a vehicle for underpinning sustainability. These legislations can also provide the basis for enabling the control and licensing of activities specific to the tourism sector and for the undertaking to certain action to support tourism development (Organisation v. s. , 2013). To conclude, sustainable tourism is all about forecasting of long-term, working together examining on results and adaptive to change and the most effective thing is communication to put across the message of sustainable tourism. It is the duty of the private, public and independent sector to acquire leadership role in tackle the challenge of this sector. The degree at which the tourism industry is increasing in the South Pacific forecasts that the environmental and social impacts of tourism cannot be disregarded. Traditionally, a number of sustainable tourism activities has been carried out and is supported by the national Tourism Organization of the South Pacific countries. However, there are a number of challenges that still stay alive and need attention in order to be more sustainable tourism industry, like climate change. In order to tackle these challenges and grip future sustainable opportunities in a harmonized manner, research and development done in these South Pacific countries to handle these issues through sustainable tourism strategy plan. The tourism strategies plans would assist the tourism industry to change unenthusiastic community discernment of the industry and achieve economic benefits through sustainable practices. It believed that it would egg on business to hold sustainable tourism practices in order to meet consumers demand and to improve business performance. Sustainable tourism should be broadcasted and celebrated amongst tourists, host communities and the participants in the industry move the industry toward sustainability. Nevertheless, the commitment to change and improve must be authentic and supported on well-established procedures and actions that is to be achieved. Assignment Essay. (2016, Sep 09).

Assessing Patients Feedback On Receiving Herbal Medicine Treatment Dissertation

Assessing Patients Feedback On Receiving Herbal Medicine Treatment - Dissertation Example The basis of the finding is lined up in the literature review part, where the author has exhaustively cited examples that are arguably centralized on the herbal treatment. Understanding the importance of medical treatment, most of the literature cited here has submerged in the argument on whether clinicians should adhere in most of the clinics in the country to this right treatment. This report is a critical representation of a research done by the university polyclinics with the help of the social research institutes, on patients’ views on the effectiveness of the herbal Medicare. Recently complementary and Alternative medicine has been seeking to gain greater acceptance into the community and thus there is the greater emphasis for it to be taken first as a professional course. Thus the University of Westminster has the mandate to ensure all its students reach an acceptable standard that can be in a position to meet patients’ needs before awarding them a degree. First, the research has touched on the patient-centered care, where special issues and barriers have been put into the analysis (Barnes, 2009, pg34). After the target groups, which are the practitioners and some of the Herbal medicine students, have been identified, the next thing is to illustrate questionnaires and outline the data found by analysis them in a more strategized manner. After the above have been met, methodology and data analysis designs have been included, for the implementation purposes (Sinclair, 2010, pg42). It is better to understand that without a detailed analysis of the data, the target group might not give out clear variations and impact of herbal being included clinical treatment.

Managing Health and Safety in the workplace Assignment

Managing Health and Safety in the workplace - Assignment Example This research will begin with the statement that legal provisions require employers to perform health risk and safety assessment. A typical risk assessment involves identification of health hazards and the associated risks at a workplace as well as how to deal with them. It is a legal and ethical requirement in any given workplace and is a key contributor to the business success through cutting down costs. Since fitness promotes body health, much of the health hazards are minimized. Nonetheless, health hazards are encountered at the training gyms. The gym-goers have high exposure to germ infection through the training equipment, water fountain or in the locker rooms. Infections like cold an athlete’s foot are easily transmitted to the training facilities. The training staffs at the fitness centers are exposed to hazards like clouds of dust and accidents from the training equipment. Similarly, the members undergoing training are exposed to these hazards alongside the side effec ts that may develop from improper exercise and equipment malfunctioning. Having identified the health hazards and the associated risks, the management of an organization evaluates the risks of exposures that go beyond the occupational limits and necessary adjustment made. This could include ensuring proper hygiene during training and improving the condition of the training facilities. The halls need not be dusty. The different legislation, like Chapter 16 of the Russian labor code, has existed in Russia that promotes health and safety of workers at the workplace. As a fitness center that is concerned with promoting the health of the individuals, Russian Fitness Center understands the potential health hazards and risks facing the employees and the members of the club, especially during training. The center requires and encourages no sharing of facilities like towels, sweatbands, razors, and goggles. The training equipment is cleaned daily with disinfectants after the exercise to avoi d germ transmission. The center has developed modern training facilities that are dust-free. At the same time, it encourages the trainees and trainers to put on water shoes to prevent cases of athlete’s foot. All the injuries need to be reported to the concerned personnel and appropriate first aid mechanisms taken. Similarly, the work environment should be properly arranged with the materials, tools, and equipment stored safely in their respective places in order to minimize injuries. This is in place at the center. The work area has to be kept clean and tidy and the operator has to check all the training equipment for safety before they are used. Besides, the training equipment should be maintained and operated by qualified personnel. Unqualified staff contributes to the risks. Members need to be guided on the use of gym equipment. The individuals using equipment should be aware of the mechanism of stopping the machine in case of an emergency. All these requirements are fulf illed at the fitness center. The fitness center has put in place most of the measures that comply with the health and safety policies in Russia.

Asses project risks Assignment Example | Topics and Well Written Essays - 500 words

Asses project risks - Assignment Example This would thus increase the cost of repairing the damages and increasing the labor cost. Furthermore, this risk is high since it is beyond the control of the project management. The second event that poses risk to the irrigation project is the delay in the delivery of the materials that will be necessary in constructing the water routes (Larson & Gray, 2011). The delay in such delivery risk bringing the project to a halt hence leading to non-achievement of the projects objective. This risk can be minimized by ensuring that reliable suppliers are contracted to deliver the materials and communications made in time. The third event that poses the risk to the project is the destruction of the plants when being planted or pruned. In such cases, the cost of purchasing additional plants or that of paying for the additional labor cost will negatively affect the project implementation. It also has the risk of delaying the completion of the project. Furthermore, destruction of the plants may lead to poor delivery of substitute plants, which are not of the same quality. The fourth event that poses risk to the irrigation project is labor disputes. In such a project, the number of persons employed is many and range from those with specialization and casual laborers (Linkov & Ramadan, 2004). Any delay in the payment of their remuneration or low rewards could make them down their tools and delay the timely completion of the project. Moreover, in the event that the equipments used in the building of the irrigation scheme is destroyed, the project could take longer periods. The cost of repairing the equipments will also increase the cost of the project hence resulting into total failure. Breakdown in the equipments could also arise when the actual digging is taking place and substandardised equipments have the potential of derailing the quality of the future construction or buildings.

Causes of Domestic Violence, Suggestion of Solutions Assignment

Causes of Domestic Violence, Suggestion of Solutions - Assignment Example The school argues that humans are biologically programmed for causing violence. To some extent, this appears to be correct. People or for that matter an animal also becomes violent if he is deprived of his most basic need that is food for survival and attacks his opponent who is there to snatch away his right. Similar is in case of sex. Up to this, there is no difference between human and animal but beyond this, there is a difference. Humans have more and more possessions, positions, social status, and honor. Anybody usurping on these parts become the subject of violence inflicted by the person who tends to lose in the process. There is another school of thought who advocates that human beings are bio-social animals and his conduct is determined both by biological and social needs.   Eysenck and other Socialist try to explain the violent and anti-social behavior in terms of social factors such as inequality, poverty, lack of housing, lack of basic resources, lack of dignity, honor in the society, social injustice and many others. WMS Russell puts his view that there is a distinct correlation between Violence and overcrowding. He cites the examples of an animal world where this symptom is found and can be extended to human society. Other social scientists refute this analogy and counterattack that there is no such evidence found establishing a direct relationship between violence and Overcrowdings. Overcrowding and violence may be associated in certain groups but can't, therefore, be taken as a general premise that they are always correlated.

Finance and accounting Assignment Example | Topics and Well Written Essays - 1500 words - 1

Finance and accounting - Assignment Example In contrast, the income distribution for women is highly skewed towards higher income range. The median for men’s income is 2217.5 while the media for women’s income is 1437.5. On the other hand, the mean for men’s income is 2635.95 and the mean for women’s income is 1417 signalling a large difference in income between both groups. Men as well as women see highest income frequency for incomes between 1500 and 2000. In the case of men’s income, the outliers are present beyond the income level of 7000. In the case of women’s income, the only outlier is in the 3500 to 4000 range. Men’s income is more affected by outliers as expressed by the standard deviation of 1701.16 while women’s income is not as deeply affected by outliers as expressed by the standard deviation of 751.55 (Freeman et al., 2007). Outliers for men’s and women’s income distribution can be dealt with by employing statistical corrections such as by converting the data to a normal distribution. Moreover, the outliers in the case of men can be seen as aberrations from the normal distribution of wealth and can be neglected altogether given the fact that these deviations affect the population sample’s credibility. The outliers are not only placed well away from the regular distribution but present an insignificant proportion of the overall sample set. It could be reasoned that these samples originate from clients who do not otherwise fit into the socio-economic group being studied. The same is true of women’s income. The aberration results in small frequency counts that are placed well above the regular income distribution pattern. Similar to the men’s case, the outliers in the case of women can be ignored to produce better results. The answers for part (a) and part(b) tend to differ from each other based on the use of a normal distribution curve and the use of the actual sample. Using the

Nature versus nurture Essay Example for Free

Nature versus nurture Essay Every person in this world has their own distinctive personality and behavior. People may wonder why an individual may act the way they do. Thus psychologists had put this into a study of whether an individual’s behaviors are caused by hereditary or the environment. This study is known as the nature-nurture debate. This essay will discuss the difference between nature vs nurture, which one applies to me, and how it influenced me in my life. This controversial debate has existed since 1869, when the phrase Nature Versus Nurture was coined by the English polymath, Francis Galton. Throughout different time periods, this controversy continued with two contrasting scientists leading the debate. During the Greek Classical period, Plato, who favored nature meaning the genetic influence on the individual’s behavior that relies mostly on traits that you inherit. While Aristotle, who favored nurture meaning the effect the environment has on that individual which relies mostly on time spent improving a skill set, for example influence of parents or friends. The purpose of the nature-nurture debate is to explain the effect of genetic influence and the environment on the development of human trait and behavior. As far as nature goes there are many traits that I have inherited naturally through genetics from my mom and dad. From my dad I can tell I have inherited his height as well as his eating habits. I can tell that my work ethic has been inherited from my dad because he is a very hard worker and can never sit still, I also strive to achieve my personal best. My dad is also a very controlling and demanding person in which I see myself doing also. While from my mom I have inherited her good looks, sensitivity, and concerned for other people’s feelings. I have also inherited my mom’s super mathematical skills and my dad’s artistic abilities. I can also tell that I have inherited a good sense of wellbeing from my mom. Alongside that came nurture that are behaviors that I have developed from the environment I grew up in. I have learned to respect all people from being influenced at school and in the home. I have also learned to be responsible of things such as going to school or work on a daily basis, and doing the right thing. I learned that if I am not responsible and do not do my work, then I must pay the consequences. I have also learned from experiences that if I do what I am supposed to do, I may be rewarded greatly for it. I have been influenced to do something that will benefit myself and be rewarded for good things done. My environment has influenced me in many ways to act upon certain things automatically. Things like looking both ways before crossing the street, or other things that appear to be common sense are learned from nurture. When I say which one of these phrases â€Å"nature vs nurture† has more influence on me in my life, I would have to say nurture, because my past experiences is what made me the woman I am today. In most instances, the aspect of nurture tends to apply to children who live with their parents. The way I was brought up affected me now that I am an adult. This is because nurture is a product of a person’s childhood upbringing. There tends to be various external influences relating to nurture that affected my behavioral as a person. These include environmental factors such as the parental upbringing, the peer groups, the socioeconomic status, and other factors in the outside world.

Manufacturing Process of Bricks

Manufacturing Process of Bricks A brick has been a common construction material used everywhere for more than 6000 years, and has been in various shape, sizes and were made by mixing many different type of materials, each of them having their own advantage and disadvantage; and formed the basic structure and the back bone of many civilisations and was used in a wide range of buildings in centuries from building palaces, housing factories, in tunnels construction, water ways, bridges, making it the oldest manufactured building material. For centuries, the brick making process was done by hand, and involved clay being moulded and then dried in the sun until the industrial revolution when the process turned to mechanization. Today technological and mechanical advancement has helped to have a more complete knowledge of the raw material and its properties, and better control of firing, improvement in the kiln designs, all have contributed to the advancement of brick quality and has made contemporary bricks more efficien t and has improved the overall quality of the products. Today, brick is found in various materials and made in various shapes depending on the use. There are concrete brick, calcium silicate brick, clay brick and Adobe brick. See Appendix 1 This report will be looking at the technology associated with the manufacturing process of automated and traditional soil clay brick, adobe brick plain mud brick which are still use today in certain part of the globe or sometimes and slump brick- and the future of brick. PART ONE MANUFACTURING PROCESS OF AUTOMATED BRICK The first stage in the manufacturing process of the soil clay brick start with the selection of the raw material. RAW MATERIAL The main raw material in brick making is clay and it is one of the most abundant natural mineral materials on the planet. On earth, there is a wide range of clay which varies considerably in physical properties, colour, hardness and mineralogical content; making it difficult to pinpoint particular clay and say this is the best clay for brick making but they do, however, have certain properties in common. PROPERTIES and TYPES OF CLAYS Clay is complex material as individual, and their deposits is unique due to their specific modes of formation and physical characteristics, and are rarely present as pure minerals but rather are mixtures of the different clay types of one group or type normally being dominant. But the Clay entering in brick manufacturing must possess and fulfil some specific properties and characteristic such as the ability to be crushed and mixed with water to form a plastic material which can be moulded into various shapes; shrinkage or swelling percentage on firing, meaning when subject to appropriate temperatures the clay particles must fuse together; the bloating characteristics, meaning the percentage of water absorption; firing colour, meaning the colour of the brick after drying and percentage of fines produced upon crushing and fire strength and these physical properties determine their commercial value. The clays from which burnt bricks are made may be divided into three principal types, all of which have similar chemical compositions but different physical characteristics. They are: 2. A Surface Clays also called Alluvial and Drift Clays Found near the surface of the earth, may be the up thrusts of older deposits or of more recent, sedimentary formation; are readily worked and require little preparation. 2. B Shale clays or rocky clays Shale is sedimentary deposits clays that have been subjected to high pressures until they have hardened almost to the form of slate which are often difficult to work and necessitate the use of heavy machinery to extract but, may be brought into plastic condition by long weathering (i.e. by exposure to rain, frost and sun) or by crushing and grinding in water, and they then resemble ordinary alluvial clays in every respect. 2. C Fire Clays Fire clays are usually mined at deeper levels of the earth than other clays where they form the bed layer under seams of coal and have refractory qualities and a high degree of resistance to heat. MANUFACTURING PROCESS The process of making clay brick is generally uniform, although manufactures tailor their production to fit their particular raw materials. In general, the manufacturing process consists of essentially of six stages: Mining and Gathering raw materials Preparation of raw material (crushing, grinding, screening and mixing the raw materials) Making of the brick or Forming Process (forming, cutting and coating) Drying Curing ( firing and cooling) Packaging and storing Diagram of the industrial manufacturing process of clay bricks MINING and GATHERING RAW MATERIALS The choice of the mining method of clay will depend on the kind of clay, on the depth, thickness, hardness and physical geology of the clay location under the ground. The general method of extracting clay from the quarry is once or twice a year using heavy plant machinery to stock pile large amounts, so to ensure continuous brick production regardless of the weather conditions and because clays are rarely present as pure minerals but rather mixtures of the different clay types; laboratory testing of the clays from different parts of quarry will determine the characteristics of the layers and will be stock in separate different categories which will facilitate the blending of the raw materials. PREPATION OF THE RAW MATERIAL In the manufacturer, the clay rock is crashed and reduced in smaller particles, and then the material produced is screen through an inclined vibrating screening machine to control the particle sizes prior to water being added. During the screening, manufactures adjust and compensate the different variations in chemical composition and physical properties by blending clays from different locations and sources to fit their standard of the end product. Consequently, to fulfil their requirements of perfect clay for bricks making, or for the composition of the raw material to fulfil their standard, the different mixes and proportions of clay and chemical are blended together, prior to add water, as which of them affect the working properties of clays causing them to vary in their behaviour affecting the properties of the final product. At the same time, manufacture has standardized their end product and their manufacturing processes to limit variations in the processing and the inconsistency in end product. For instance, a clay brick that when cure turn white may be developed commercially because, by adding various minerals like oxide of iron will affect the propriety of the brick in such a way that when cure it will produce a red brick if also there is consistency in the manufacturing processes. Example: Clay containing from 5 to 8 % of oxide of iron will, under ordinary conditions of firing, produce a red brick; but if the clay contains 3 to 4% of alkalis, or the brick is fired too hard, the colour will be darker and purple. An excess of Alumina compound tending to make the colour lighter and brighter. FORMING OF THE BRICK The first step in forming process is to produce a homogeneous plastic clay mass work up into proper consistency by adding water to clay in a mixing chamber with one or more revolving shafts with blade extensions. After the kneading, the plastic clay mass is ready for forming. There are three different methods of shaping and forming brick: the stiff-mud process or extrusion process 6. A. The stiff-mud process or extrusion process In the stiff-mud process or extrusion process, the clay is mixed with just enough water to produce clay plastic mass with water in the range of 10 to 15 percent of the clay mass. Next, the clay is extruded through a die, producing a horizontal column of clay which passes by conveyor belt through an automatic wire cutter to create the individual brick. The cutter spaces and die size are precisely calculated to compensate for shrinkage during drying and firing. 6. B. Soft-mud process In the soft-mud process or moulded process, the clay contains too much water to be extruded. The plastic clay mass contain 20 to 30 percent of water per mass is used to produce brick either by hand or machine. In the machine driven soft-mud process, standard brick are produce in mass quantities as the machine replicate the hand-making process much quicker. 6. C. Hand making In the simplest form which is done by hand, the craftsman will produce one brick at the time by stuffing a lump of soft clay in a mould and the excess clay is stuff from the top of the mould and the brick is turned out. The mould is lubricated with either sand or water to prevent the brick from sticking in the mould. 6. D. The dry-press process In this process hydraulic or compressed air rams is used to press clay with very low plasticity, containing no more than ten percent of water by weight, into steel moulds under pressures from 500 to 1500 psi creating a very compact and dense brick. DRYING PROCESS Prior to the brick to be fired in the kiln, after the brick is formed using any of the method describes above, it containing 7 to 30 percent of moisture, depending upon the forming method. This moisture must be removed prior to the brick can be fired in the kiln otherwise, there will be formation of scum and certain mechanical defects from occurring or the brick will explode when the brick is subject to the intense heat of the kiln. This drying process which last about 18 to 40 hours, is normally done by placing the green brick in enclosed dryer which utilize excess heat supplied from the exhaust heat of kiln to maximize thermal efficiency. To ensure good result, devices are installed to measure and control humidity in the drying facilities. A. Firing After the drying, the brick are fired in furnace chamber called kiln for 10 to 40 hours, where there are subject to a temperature of ranging between 100 to 1200 degrees centigrade depending on clay type or material used and the type of finished brick required. During the process, clay particles and impurities will undergo changes as the temperature in the kilns rises. The remaining water in the brick will dry up or evaporate; unlike the metal, clay softens slowly and melts or vitrifies gradually in rising temperature. The clay molecules mass breaks down becomes soft enough to stick together; the mass becomes tight, solid and non absorbent giving the brick it texture and colour. To ensure a good product and avoid the brick to be deformed due to heat also called viscous fusion, kiln is fitted with sensors to control the temperature in the different stage the firing process. 7.A.1. What is a Kiln? In brief, kilns are just containers for heat; fuelled by natural gas, coal, sawdust, and methane gas from landfills or a combination of these fuels. There are many different types of kilns but the most common types are the continuous kilns (tunnel) which are always firing; they never cool and are capable of turning out large quantities of bricks at steady constant rate and the periodic (intermittent) kilns which are fired on an intermittent schedule. http://www.pottery-magic.com/pottery/history/bottle_kiln.htm PACKAGING Following the firing process is the packaging but prior to that the bricks are gradually cool down, for 10 hours for tunnel kiln and form 5 to 24 hours in periodic kiln, as the rate of cooling affect directly the final colour of the bricks. After the brick has cool downs, there are unload from the kiln; sorted, graded, packaged and place in a storage yard or loaded rail cars or truck of delivery. PART TWO MANUFACTURING PROCESS OF ADOBE CLAY BRICK The adobe brick, this type of earthen building materials has been around since the beginning of civilisation and has been the main building material for most of the civilisation. In our day, Adobe are mostly used in hot and dry climates and become the characteristic of the third world. Although this is a very old material, it manufacturing process hasnt change since. As with the soil clay brick the main ingredient which enter in the manufacturing process is clay and the manufacturing process start with the choice of the raw material. SELECTION OF RAW MATERIALS Adobe brick are made from a mixture of mud or clay and small pieces of straw or reeds, and are formed by hand and left in the sun to dry. The secret of make adobe bricks lays on the choice of the type of clay to use as it is made of surface clay soil. Although the bricks are made in rural area where there is no sophisticated laboratory for testing but prior using the clay it has to be tested. The testing of the clay can be done by filling 2/3 of a graded glass jar with the clay you plan to use, and then fill the jar with water and put a lid on. Shake the jar for about two minutes making sure the clay is totally mix up with the water then let the jar and the mix to sit overnight. After about 24 hours, examine the jar and its content; the clay would have broken up into two distinct bands of sand on the bottom and clay on the top. There should not be more clay than sand on the ration of 30 percent clay and 70 percent sand for an ideal adobe brick making clay. EQUIPMENT NEEDED Clay soil Measuring Tape Hammer Hand Saw 24 timbers Nails Shovel Bucket Water Straw PREPARATION OF BRICKS After selecting the clay, an area must be clear prior to start making bricks and a shed to protect the newly made against the rain as it can take a couple of days for them to dry. In the nearby, dig a hole of about 3 to 4 feet long, 2 to 3 feet wide and 2 to 3 feet deep as a mixing pit for the different ingredients. Then fill the hole with water and let it drain out as this will strengthen the wall of the hole for it not to crumble while mixing the clay soil. This will take at least a day to dry out.  Make mould of the bricks using timber. The traditional size is 4 by 10 by 14 inches and this is made with 2 by 4 studs nailed into a ladder like shape. MAKING ADOBE BRICKS Once the water in the pit has dry out, fill the pit halfway with the clay soil then add water gradually as mixing with the feet our shovel until the mix is stiff. Straw can be added to reinforce the mix but it is not necessary.Fill the mould using a shovel or hand thenlevel off the excess with the shovel or with a straight edge, makingsure there are no air pockets or gaps.  Let the bricks set and then gently remove the mould from them leaving the wet adobe bricks to dry for several days (at least three) before handling. Wash the mould and repeat the process in a different area. DRYING PROCESS Leave the adobe brick where they are while they dry in the sun for several days before turning them on the edge to completely dry out and harden and put under the shed so that the drying time can continue. When the edges turn white, they are ready to be moved, but not used. This process could take at least 3 weeks prior the brick is use. PART THREE THE FUTURE OF CLAY BRICK As the world population is growing especially in developing countries, there is a need of urbanisation to accommodate this populace meaning more bricks are needed to answer to this demand of infrastructure development. With the growing problem of energy price soaring, with the world running out of fossil fuel, with the reduction of deforestation which encourages the expansion of the desert, the clay brick industry is now facing an energy crisis and this crisis is affecting and will affect everyone. In the developed country, it is affecting the price of the accommodation and the house price while in the developing country it is leading to the impoverishment of many. This crisis resound as called for innovation by funding a new way of making new type of clay brick or improving the firing process by a new design of kiln aiming to reduce energy consumption by minimizing the energy required by the process as firing time and temperature in the kiln are the two key factors which contribute in the making of solid brick. In the developed country, electricity and fossil fuel are use as the main fuel source for brick firing as they are abundant. Founding other alternative to these sources of energy could be the way forward. But investing in nuclear power will raise an environmental issue of dealing with the nuclear waste; investing in the renewable energy will be a gamble in the way that, most of this technology are still in embryonic state and will require funding a good spot to install them and a big area to cover to be able to produce enough energy necessary to power this industries such investment will impair on the price of brick. It will mean also to divert energy which will be helpful to thousand household into industry. UNFIRED CLAY BRICK The way forward will be probably in reducing the energy consumption by designing better kiln and improving our knowledge of the minimum energy required by the process as unnecessary prolonged firing time and too high temperature will eventually consume more energy but minimum firing temperature and shortening firing time do not only reduce energy but also increase the productivity. In the developing country, this crisis reverberates as called for innovation, finding an alternative for curing clay brick as they are facing desertification. Curing is done, depending on the area, by fire wood, rice husk and maize cob or residue as main fuel sources for brick firing because they are abundant in developing country. Even though other agricultural waste such as saw dust and oil palm shell are used as substitute for wood, a new design of kiln is necessary to cope with the small size of fuel. If thinking in term of innovation in finding a new way of making clay brick, the new brick should be energy efficient in manufacturing process especial if cure through a kiln. Although the adobe clay brick may seem to be the answer but this brick however is not very strong or durable and tend to crack on drying. But one of the modern additions is to compensate this weakness by mixing soil clay with sand and stabilizing it with 4 to 8 % of cement or gypsum and then compress these materials in a given mould form, which results in strong and durable bricks, which do not crack. This is done with simple and yet innovative manually or engine-operated brick presses made from substantial steel sections with axle steel shaft with a top round shaft is case hardened carbon steel with a lid and with a bottom that moves up and down; the compression given by the machine compact the soil particles together to make dense regular shaped brick, usually 300x300x 130 mm in size and it is use  to produce interlocking soil clay bricks without burning. MANUFACTURING UNFIRED CLAY BRICKS This process uses the same type of clay use for the adobe brick. After the soil clay has been selected, it must be properly mix with Portland cement or gypsum then add water to the content so that the final product is a dry mixture containing about 15% water by weight. The dry mixture is poured in the mould of the press machine which is compress by pushing the press lever from one side to the other after closure of the top with a steel lid, with a force of about12 to 14 tons mould pressure. After the compression finish, the brick is eject from the machine and stack in the way to prevent water loss. Water is added daily so that the cement can be hydrated properly. The curing process will take about 28 days.   ADVANTAGES This Environmentally-sound building process is practical, inexpensive and  environmentallyHYPERLINK http://www.articlesfactory.com/articles/environment/soil-brick-making-machines-can-save-the-forests.html  HYPERLINK http://www.articlesfactory.com/articles/environment/soil-brick-making-machines-can-save-the-forests.htmlfriendly, as well as significant in cost savings and on-going green benefits, building with unfired soil clay bricks is one of the solution for the housing crisis because it has a lot of environmental benefits. Figure 2 The environment is protected in several ways: It lessens the ecological impact of building construction, thereby reducing deforestation and the need kiln. There is hence no need to burn the bricks, which makes this process a very low-energy requiring one. It saves money as the brick can be made On-site eliminating transportation, middlemen and breakage cost. On the other hand, unfired clay brick provide a sustainable and healthy alternative as replacement to conventional masonry materials. The structures made with soil bricks are as beautiful and durable as housing made from conventional bricks with the higher acoustical qualities that shut out exterior noise for less stressful living and reduce the need to heat or cool the interior. The soil brick is suitable especially for use in multi storey buildings, due to its durability and robustness. The bricks are already strong enough to be handled for storage when they leave the machine. Brick presses allow countryside people to build independently their own affordable bricks to self-build their houses and not have to rely on salesmen and production in towns, bad roads, transport problems and fluctuating prices. CONCLUSION The lack of fossil fuels the world will face shortly will drive the world in an economical crisis which we havent experience before driving up the price of accommodation. Though the idea of compress clay bricks from soil is far from new in the developing country, but for some unknown  reasons this technology doesnt seem to have made its brake through the developed world. There is a need to implement this new product of a low carbon footprint in the building industry.

Clinical dentistry :: essays research papers

Fundamentals of Clinical Dentistry: Intro to Indices and Charting Specific Objectives: 1) Define the purpose of dental indices, such as DMF-T, DMF-S, Gingival Inflammation Index and Plaque Index. Dental indices are important tools used in examinations to provide a numeric score that quantifies the magnitude of the disease measured. DMF-T: The number of teeth that are decayed, missing, or filled, the DMFT index, is a total score of all affected teeth and provides a caries experience score for an individual. DMF-S: A count of tooth surfaces that are decayed, missing, or filled and provides a greater precision about the caries history of an individual or a population group when mean scores are derived. Gingival Inflammation Index: Provides an assessment of gingival inflammatory status that can be used in practice to compare gingival health before and after dental visits and or treatments. Plaque Index: Same as Gingival Inflammation Index but deals with plaque. 2) Differentiate between the terms prevalence and incidence of a disease. Disease Prevalence: The number of decayed, missing, and filled surfaces that exist in the mouth at any one time. Only one examination is required to determine prevalence. (Prevalence is what is present at one point in time!) Disease Incidence: The number of decayed, missing, and filled surfaces that occur over a given period of time. Two different examinations are required to determine incidence- one before, and one at the end of a selected time period. (Incidence is what happens over a period of time!) 3) Describe the rationale and demonstrate how to chart existing restorations (amalgam, composite, gold, crowns, bridges, other), missing teeth, incipient caries and caries. Rationale- Well I think this is pretty common sense. Charting the information listed above will give you a record of your patient. This record can be reviewed upon future visits to note and record any changes. If you want me to explain how to wipe the fog off a mirror against the inside of your patient’s cheek, let me know. I also think I could get the point of a modified pen grasp across if someone really needs the help. Code for Dental Charting Existing Restorations: Fixed bridge (3 units)- Outline tooth crowns and place an X through tooth root to indicate which tooth is the pontic. Crown- Outline tooth crown and use diagonal lines to indicate gold. Non-metallic restoration (e.g. composite)- outline margins of the restoration. Metallic restoration (e.g. amalgam)- fill in the shape of the restoration with blue pencil. â€Å"Cracked† or â€Å"chipped† restorations- use red pencil to outline the existing restoration.

Philosophic Thought in Whitmans Song of Myself :: Song of Myself Essays

     Ã‚   The Heath Anthology of American Literature repeatedly refers to Walt Whitman and his poetry in terms of being American, yet as I read Song of Myself, my thoughts are continually drawn to the philosophies and religions of the Far East. Like the Tao Te Ching ideas are expressed in enigmatic verse and each stanza is a Zen koan waiting to be meditated on and puzzled out. Even Emerson called Whitman's poetry "a remarkable mixture of the Bhagvat Gita and the New York Herald" ("The Whitman Project"). Song of Myself contains multitudes of passages that express Hindu, Buddhist, and Taoist thought. Hinduism is an ancient religion of India and the Bhagvat Gita mentioned above, is among its holy texts. Meditation is emphasized in Hinduism and the point of meditation is explained in a famous metaphor: the mind is a tree and in this tree there is a monkey and a bird. The monkey, called the slippery monkey, races about, chattering constantly. If one can silence the monkey then the bird sings. Whitman could be describing the concerns of the slippery monkey when he writes: "The latest news . . . . discoveries, inventions, societies . . . . authors old and new,/ My dinner, dress, associates, looks, business, compliments, dues/ . . . But they are not the Me myself" (lines 60-65). A description of the bird can be taken from the same passage: "Apart from the pulling and hauling stands what I am,/ Stands amused, complacent, compassionating, idle, unitary" (lines 66-67). Whitman requests of the bird, which he refers to as the soul: "Loafe with me on the grass . . . . loose the stop from you r throat" (line 75). When the bird complies, Whitman writes that the bird "plunged . . . tongue to my barestript heart . . ./ Swiftly arose and spread around me the peace and joy and knowledge that pass all the art and argument of the earth" (lines 80-82). By stilling the slippery monkey and hearing the song of the bird one gains enlightenment (this is similar to shedding the ego in order to attain enlightenment in Buddhism. Sidhartha, the founder of Buddhism, was a Hindu before he rejected its tenets). Part of Hindu enlightenment is the realization that all is Brahma and Brahma is all. Hinduism is polytheistic, but all its many gods are only aspects of the one God, Brahma.

Wright Brothers History :: History

The Wright Brothers As an up and coming journalist for my hometown paper, the Dayton Daily, I was thrilled to learn that my first major article would be on none other than Dayton’s very own Wilbur and Orville Wright. The year was 1896 and the Daily wanted me to write an article on the brother’s bicycle shop, The Wright Cycle Shop, which was gaining popularity among the locals. Although I was excited about being given my first assignment, I couldn’t help but feel a little disinterested in the subject. I mean, bicycles had been popular for some time now and there were already scores of publications and articles on the two wheeled wonders. I didn’t want to write a same old song and dance article. I had ambition, talent, and drive. I wanted to write an article on something that would change the world, something people knew very little about, something inspiring. Although I couldn’t wait to make a name for myself, I decided to put my dreams of grandeur at bay and focus on doing a great job on my first assignment. When I met the two brothers, originally from Indiana, they were pleased at the idea that their cycle business would be the subject of attention for a newspaper article and they agreed to divulge any information that would help me write the piece. As the day went along I remember asking the brothers if they believed they would stay in the bicycle industry for the remainder of their foreseeable future and Wilbur’s answer is what introduced me to the brothers’ true passion. It was only a few words but at the time I couldn’t help but thinking how radical and ridiculous it sounded, â€Å"We want to fly.† I could scarcely believe it but I was intrigued so I pressed them for more information. They began to tell me about their following of Otto Lilienthal record setting glides in Germany and their intr igue in the subject of flight. Skepticism filled my head but as a journalist, I knew that this was practically uncharted territory and if the brothers were to make strives in manned flight, I could possibly be in on the ground floor. I simply couldn’t pass up this opportunity so I talked the brothers into letting me check in with them from time to time in order to keep me up to date on their progress.

Gender Roles and Marriage

The representation of gender roles and marriage has always been a controversial issue. However, much can be learned about unhappy marriages when examining the roles of both females and males within the marriage. The examination of gender roles and marriage are seen through the following short stories The Story of an Hour, The Necklace, and Country Lovers, along with scholarly articles based on gender role and marriage. Evaluation of these literary works shows quite clearly that social and economic class affects choice in marriage. Gardiner’s County Lovers presents its fairly clear theme right from the beginning of the story. Yes, there is a theme of race, but if you look even deeper you can see the underlying idea of marriage and gender roles. There is a love between two people but it is forbidden due them being a part of two separate classes. In the marriage that takes place between Njabulo and Thebedi there is an absence of love. Thebedi agrees to marry Njabulo because it is what is expected of her, but this does not constitute what many see as a proper marriage. There are some prevalent gender roles expressed in this story. There is are not many females described in the story other than Thebedi, but those who are discussed always have the role of being silent, and that of a domestic worker. Thebedi is often described as being the primary care giver of her children, whereas Njabulo and Paulus are often described as holding careers outside the home. The gender roles in this story are very stereotypical. Thebedi is portrayed as being weak and helpless and she stands outside her hut while Paulus is alone with the child. She knowingly left her child alone with Paulus after he strongly expressed his dislike of the situation of her having his child. The author portrays her as being helpless and innocent but the death of her child could have been prevented if she wanted it. The point of view of this story is that of a third-person. The narrator was not involved as a character in the story, which made it harder to get involved in the story emotionally. There was little connection to the inner thoughts of Thebedi and Paulus. This made theory very limited, in that the narrator knew of the events but not of their experiences. This objective view could have been improved by connecting the reader more to the thoughts and feelings of Paulus, Thebedi and Njabulo. In the end of the, Njabulo decides to stay with his wife and continue living as a family with their new born child. There is little said about how he felt about the whole situation, when in fact the decision he made was a very big one, but would have taken a lot of thought and contradictory feelings. The tone reflected by the author was very somber and solemn. From the begging there was much negatively expressed towards the thoughts of love and marriage. There is a verbal ironic one use when all evidence persuades the reader to think that Thebedi and Paulus will be in trouble or their actions, but in the end their relationship was not acknowledged and they are both able to walk away and live their lives freely. The language used by the author also suggests gender inequality. As Thebedi is 18 years old and Njabulo is 19, Thebedi is still being called a â€Å"girl† and Njubulo is considered a â€Å"man†. Within the story The Necklace the theme of changing gender roles within the married couples is prevalent. Madame Loisel did not marry for love, but rather married because it was expected of her. She married a man who worked in the Ministry of Education and had little money. Mr. Loisel, however, did marry for love and was very satisfied with their life together. Mathilde Loisel did not respect her husband due to him not making as much money as she would like, and she is portrayed as always wanting more. Her husband tGries hard to do anything to please her and makes sacrifices to keep her happy. Mathilde uses her innocence to gain sympathy, which leads to her getting the possessions that she desires. She is presented as being a weak and needy wife who cannot care for herself, relying on her husband to survive. When the Loisel’s had to earn more money to pay off their debts, Mr. Loisel takes on a second job working outside of them home while Mrs. Loisel works in the home cooking, cleaning, and taking on the care giver role. In the begging of the story it seemed as though Mathilde held most of the power in their marriage, but once conflict arose the power shifted back to Mr. Loisel, as Mathilde continued to do exactly what he said without questioning. This story is also told from a third-person point of view. The narrator is not part of the story and presents the action to the reader from on outside view. The reader is able to see everything through the eyes or the narrator, but the reliability is questionable in that the information coming from a third party. The style of writing is very fluent and easy to follow, which makes for a very enjoyable read. deMauppassant uses situation irony in a creative way to give the story an humorous twist; when Mathilde finds out the diamond she and her husband have been working so hard to pay off, was actually imitation. This discrepancy allows the author to add humor, giving the story a light and playful tone. The use of satire exists towards the end of the story in the form of a farce. Subtle humor and hilarity is developed through improbable situations and exaggeration. In this situation the probability of Mr. And Mrs. Loisel going through ten years of misery and poverty just to find out the diamond was fake, is very low, which is why it makes the story so humorous Kate Chopin’s The Story of an Hour also displays a theme of an unhappy marriage. When Mrs. Mallard received the news about her dead husband she began to weep uncontrollably, only to figure out she was weeping out of joy not sadness. Mrs. Mallards journey thorugh her thoughts help her to realize just how unhappy she was in her marriage, and how much better off she will be living for herself, and only herself. Although this story is mostly about Mrs. Mallard, it still gives a sense of the stereotypical gender role. An early mention of Mr. Mallard sates that Mrs. Mallard was repressed by him in their marriage life. Mrs. Mallard’s constant joy (after hearing about her husband’s death) suggests that she wanted to leave her husband but did not have the bravery to do so. Also, men are portrayed as the stronger sex as Josephine comforts her sister as she cries in her arms, while Richard stands by and watches. The female takes on the role of the nurturer and comforter as the male takes on the role of the strong, silent type. The narrator, although a third-person point of view, does a great job of providing an in depth description of Mrs. Mallard’s feelings toward the whole situation. The action is presented through an outside view, displaying the characters thoughts and feelings toward the death of Mr. Ballard. Although most events are sensed through the eyes or the narrator, they do a great job of getting in touch with Mrs. Mallard’s feelings, so the reader can connect better with her, and how she is reacting to the situation. The narrator’s omniscient view is very refreshing and informative. Chopin uses a combination of verbal and situation irony to add humor to the situation. Throughout the story, it is explicitly expressed how each character feels about the unfortunate death of Mr. Mallard. As Mrs. Mallard chants â€Å"free, free, free! † to her in the bathroom, it leads the reader to believe that the deal of Mr. Mallard is accurate and Mrs. Mallard is ready to move on with her life. When Mrs. Mallard finally comes out of the bedroom, feeling quite positive about the situation, shock arrives on everyone’s faces as they find out Mr. Ballard was not on the train, and is therefore still alive. Although this story does not directly speak of social class, Mr. Mallard taking the train does suggest this family within the middle class category. Joan Kahn that during since the 70’s healthy adults are starting to face new challenges unrelated to their career. These activities are productive and provide new opportunities. Some of these activities include part time employment, volunteer, and informal support to family in friends. Kahn noted the gender difference between men and women’s behaviors and relationships. While men tend to work more, while achieving outside the home, women on the other hand are more nurturing in the home. Her studies have focused on age and gender differences in housework and have shown husbands to do less housework than wives which tends to increase with age. Findings on the gender gap in forms of unpaid labor have showed that women did more work for both kin and non kin than did men. Also men showed to be happier in their marriages than women. Also, her study illustrated that women were consistently more likely than men to assist their children in some capacity, as well as those who had living parents. William Wilcox demonstrates the profound changes in the functions and stability of marriage. The rise in women’s social and economic interest has drastically increased. He states, in the from the 18th century and onwards women became more concerned about marrying for social status, than marrying for love. The emotional functions and character of marriage have and marital happiness has become less important. Marital stability; home production, childbearing, and division of labor have been determined predominantly by the stereotypes of what is expected by either gender. Wilcox states, in his gender model of marriage, that men and women are invested in doing that their gender suggests they embrace. They are raised to live up to their gender role ideology. He believes women and men are socialized to hold on to their gender typical patterns of behavior. Jonathan Vespa describes children as a changing factor on gender ideology. When married couples have children, the couples are more likely to agree that a women’s duty is care giving. The effect of employment on gender ideology also depends on life experience and economic status. Working men with an employed wife their family suffered, where as working men with a stay-at-home wife reported their family was stable. Gayle Kaufman believes gender ideology has changed greatly during the last few decades. She also believes it is important to examine the relationship between ideology and marital happiness. There is a strong connection between gender attitudes in terms of expected roles for men and women and power relations. The traditional attitudes focus on men as breadwinners and women as homemakers, with both holding different amounts of power. Nontraditional attitudes focus on sharing economic and caring tasks which divides power more equally, but this is not the majority of most marriages. Much can be learned about unhappy marriages when examining the roles of both females and males within the marriage. Throughout this paper, the effects of social and economic class have shown to have a great impact on marriage. There are many common themes within the three literary works, including the unhappiness of wives in their marriages, as none of them married for love. The examination of gender roles and marriage are seen through the following short stories The Story of an Hour, The Necklace, and Country Lovers, along with scholarly articles based on gender role and marriage. Evaluation of these literary works shows quite clearly that social and economic class affects choice in marriage.

When married couples have children, the couples are more likely to agree that a women’s duty is care giving.

Gayle Kaufman believes gender ideology has changed greatly during the last few decades. She also believes it is important to examine the relationship between ideology and marital happiness. There is a strong connection between gender attitudes in terms of expected roles for men and women and power relations. The traditional attitudes focus on men as breadwinners and women as homemakers, with both holding different amounts of power. Nontraditional attitudes focus on sharing economic and caring tasks which divides power more equally, but this is not the majority of most marriages.

Evaluation of these literary works shows quite clearly that social and economic class affects choice in marriage.
