Insulation and ventilation Research Paper Example | Topics and Well Written Essays - 500 words

Insulation and ventilation - Research Paper Example Their resistances range from 2.13 to 3.31 and mostly require installation by professionals (Department of Energy, 2008). The other type of insulation is rigid insulation that is made from plastic foams or fibrous materials. They provide a greater resistance where space is limited. Professionals apply foam insulation produced in two forms open-cell and closed-cell with the help of special equipment. Blue Flame states that ventilators are those openings in the attic that allow moisture to escape. Ventilation ensures that attic heat does not penetrate into living rooms during the summer. Natural ventilation installation should be for every 300 square feet of an attic, one square foot of ventilation is required (Blue Flame). Some of the natural ventilation types include gable vents, ridge vents, soffit vents, and roof line vents. Power ventilation utilizes attic ventilators that may hinder efficient fireplace and furnace ventilation (Blue Flame). Properly ventilated and insulated attics offer several benefits. Proper insulation and ventilation prevent ice dams by keeping the roof cooler during winter. An efficient ventilation and insulation reduce cooling costs during warm seasons. Proper insulation extends shingle life span that also prevents rot in the roof’s framing by reducing moisture build up. Improper ventilation and insulation consequences include increased costs in cooling and heating the house during hot and cold weather. Improper installation consumes energy and produces unreliable outcomes inhibiting energy efficiency. Both open cell and closed cell foam insulation are suitable for insulating. These foam installations all come in different colors and often look alike. Easley states that in open cell foam insulation, bubbles are linked and connected by air pockets with Resistance values of around 3.5 per inch. The closed cell foam spray uses tiny bubbles filled with gasses less conductive than air, forming a

Human Resource Management, Questions Essay Example | Topics and Well Written Essays - 750 words

Human Resource Management, Questions - Essay Example It is important to ensure that all employees remain customer oriented and demonstrate high level of service. Therefore, as a manager, I would propose to include the following strategies to help employees cope with stress. Firstly, employees will be recommended to attend communication skills courses to ease and improve their relationship with customers and even co-workers. Such courses will also teach the employees useful tactics in handling difficult clients. Secondly, the organization will introduce a 'buddy system', where an employee is attached to another individual to act as support for one another. The system will encourage individuals to openly discuss difficulties that they face at work and share tips for improving the situation. In addition, the system will also encourage employees to keep a lookout for alarming stress symptoms that their colleagues may be having so that these can be addressed immediately. Stress, if applied continuously and excessively, is a negative physical reaction to situations that upsets an individual's balance. On the contrary, small doses of it can actually have a positive effect on an individual by spurring him or her to perform better at something. In this case, the manager's statement is directed at Janine, who constantly experiences the symptoms of stress. Indeed, symptoms of stress can be seen in a person's behaviour, emotion, and physical conditions. Chronic stress is harmful to one's health because it disrupts the body's system, causing high blood pressure and poor immune system, increasing the risk of heart attack and speeding up the aging process. Therefore, the manager's statement about the unfavourable effect of stress on one's performance rings true. Answer to Question 4 Sammie is de-motivated because he is unsure of his skills in dealing with different kinds of people that he meets at work. As such, he feels he is incompetent to perform well at work. Using Social Cognitive Theory, Sammie's manager can motivate him by planning, anticipating likely outcomes and setting goals. Planning a course of action will help to anticipate the likely outcomes of these actions, while setting clear and attainable goals will ensure that Sammie remains challenged and motivated. For instance, the manager can discuss with Sammie the difficulties that he is facing with his job; draw up a plan to help Sammie overcome his fears, and keep a log book with daily targets, that Sammie can use to keep track of his daily experiences with the customers he has dealt with. Next, Sammie's manager can put him on a training session for a period where he will observe his co-workers on the job. This is known as vicarious learning and by such observations, Sammie will be able to retain positive points and use them in actual situations. This will also better prepare Sammie in the future. This is ideal instead of immediately putting Sammie to deal with customers because the observations will prepare him for what to expect. Self-regulating mechanisms increase self-worth and personal satisfaction by regular monitoring of one's actions. Sammie's manager

Hydropower And Wind Potentials In Hong Kong Environmental Sciences Essay

Hydropower And Wind Potentials In Hong Kong Environmental Sciences Essay For decades mankind are in search for new energy resources to deal with the depleting fossil fuel. A lot of renewable energy and associated technologies were developed to assist current energy use to mitigate the imperative energy crisis. The current issues of climate change and global warming accelerated the needs into researches on renewable technologies even more. Hong Kong is a special city with limited energy resources in a densely populated space. Current energy source in Hong Kong mostly rely on imported fossil fuels. The intention of replacing fossil fuel with other alternatives have become clear in both Government and non- Government Organisations. The Energy Efficiency Office (EEO); Electrical, Mechanical Service Department (EMSD), HKSARG has performed a study on feasibilities of various kinds of renewable energy in Hong Kong in 2001 (EMSD, 2001), the study gave an overview on feasibility of Solar, Wind, Fuel cells, Energy-from-Waste, and some other alternative energy. Every technologies was analysed, giving a conclusion that solar will be the most viable renewable energy source. The study of Tidal, and Hydroelectricity, however, was loosely studied due to the belief that they are relatively new technologies. However, although they are not being researched until very recent years, they have been used by human long beyond history. Mills that uses tidal energy has been found in the 12th century (Wallechinsky), whereas the hydro-energy was used even further back to Ancient Greek and Roman, where they use hydro-power for grinding mills (The U.S. Department of Energy). BagcÄ ± carried out a research in 2008 targeted to study the potential of developing a zero energy region in outer Island. Peng Chau was analyzed with different implementations of renewable energy and it is shown that a combination of solar, wind and hydro energy were a possible solution towards an Island that is independent from fossil fuel energy supply (BagcÄ ±, 2009). Despite the researches above, there is little research on full scale analysis on the feasibility of Hydro and Tidal energy in Hong Kong. Therefore it is of interest to determine whether the advances of technologies have gain points for Tidal and Hydro energy as potential alternative energy sources in Hong Kong. Tidal Energy Figure 1. Operating principle of Tidal Barrages (Palmer, 2008) Tidal Energy is a result from gravitational force between celestial body such as the earth, moon, sun etc., as the moon is the nearest among other celestial body, it is usually considered as the only contributor to the tidal formation. The moon rotates around the earth every 27.3 days and the earth rotates along its axis every 24hr. The net effect is that tidal fluctuation occures twice each 24 hour 50 mins, same as the earth rotation period with respect to the earth-moon system (World Energy Council, 2004). The amplitude from such fluctuation is called the tidal range, and is the energy that can be captured through a turbo-generator in tide barrage to produce electricity (Figure 1). It is suggested that Tidal energy can provides 5 % of the electricity generated worldwide (Palmer, 2008). According to the meteorological data provided by the Hong Kong Observatory (HKO), Hong Kong displays a gradual change in tidal characteristics, both in tidal range and tidal occurance of high and low tides travelling from southeast to the northwest across the territory. Within a tidal cycle, Waglan Island is the first to experience high tide and low tide whereas Tsim Bei Tsui is the last. Tsim Bei Tsui however, possess the largest mean tidal range of 1.4m, where Waglan Island and Victoria Habour generally possess a tidal range within 1m. (CEDD, 2002; HKO, 2009) Hydro energy Hydro energy shares the same energy carrier with Tidal energy, in which energy from water flow is captured with a marine turbine to generate electricity. It can be install anywhere as soon as water flow exists. Scales of Hydropower generator can be as large as constructions of dam to micro scales, usually found in small villages. Large scale generators were not considered to be implemented as no suitable sites were avaliable. In the report by EMSD, Hydro-energy were briefly analysed, and it is shown that potential of hydro-power in Hong Kong is relatively low compared to wind and solar energy (EMSD, 2001). Despite the feasilbility of Hydroelectricity dam in Hong Kong, there is a debate on the emission of greenhouse gas via this technology. A few studies had suggested that hydroelectric dam will generate three times more than fossil fuel plant to generate the same amount of electricity, in which plants died underneath an operating dam possess anaerobic digestion, generating a significant amount of GHG, especially in south America tropical (e.g. Brazil, Argentina) where hydroelectricity dam is the main source of renewable energy supply. Therefore the à ¢Ã¢â€š ¬Ã…“cleannessà ¢Ã¢â€š ¬Ã‚  of Hydropower is back in a debate (Graham-Rowe, 2005). Wind energy Wind energy is so well known and well developed that it is seen as the major potential renewable energy source that are viable in Hong Kong. Turbine were driven by wind to produce energy, scale of wind turbine are ranging from 198m high turbine generating 6 MW of electricity to some 2kW in micro size wind turbine. EMSD also analysed the potential sites for the installation of wind turbine, which a wind map was introduced for references by the public (Figure 2). Local applications include the famous 800kW wind turbine installed in Lamma Island, as well as the proposed wind farm in South-eastern Waters (EPD, 2006). Project Description This Project was targeted to review and anaylse the potential of Tidal and Hydro energy, and to compare them to the well developed Wind energy in Hong Kong. Since such energy sources are largely depend on meteorology, it is necessary to analyse as well as meteorological condition to determine which energy source are most suitable in Hong Kong. Moreover it is useful to review on current development of mentioned technologies to provide example for the implementation in Hong Kong. Objectives This project aims to: Give an overview of current energy consumption patterns in Hong Kong Provide an update on researches on Tidal, Hydro and Wind energy, these include Technologies involved and their latest development Overseas examples of application Potential strategy of implementation in Hong Kong Compare each of energy source to analyse their potential in Hong Kong, these include Meteorological assessment and potential energy gain Environmental Impact Assessment Cost Effectiveness / Costing Figure 2. Wind Power Density over the Region of Hong Kong (EMSD, 2001) Scope of Work To determine whether the technologies are competent in mitigation energy crisis in Hong Kong, it is always easier to understand how the locals use their energy, as well as the energy consumption in Hong Kong. Therefore it is reasonable to give a brief overview on energy flow pattern in Hong Kong. Energy source distribution, energy usage by different users can be obtained from the EEO, EMSD. Since Wind energy was well researched and there are a lot of applications in Hong Kong, wind energy will be used as a base for comparison with other technologies encountered in this project. Local and overseas examples will be discussed, as it provides a real life example into the application of such technologies. As mentioned before this project requires a significant amount of meteorological data, therefore meteorological observations from the Hong Kong Observatory (HKO) will be analysed to review the possibilities of implementing tidal, hydro and wind energy. Despite the HKO, observations from the Environmental Central Facilities can also available to the public for detail analysis of wind and tidal observations. (Environmental Central Facility) Lastly, if viable, a cost analysis on some of the technologies can be carry out to demonstrate the economy of such renewable technologies and thus cost effectiveness can be use as an indicator to compare the aforementioned technologies. Time Management This project is mostly a Literature Research Project with some analysis on meteorological observations. Major milestone includes: 31 January, 2010; submission of inception report 30 September, 2010; submission of preliminary findings 21 April, 2011; submission of project title and draft dissertation (tentative), and expression of intention to complete project 30 June, 2011; Oral Presentation (tentative) 8 August, 2011; submission of final dissertation (tentative) Appendix A shows a Gantt chart showing tentative schedule of the project, stating the milestones as well as phases of the project.

Female Discrimination in Intercollegiate Sports :: Athletics Feminism Essays

Female Discrimination in Intercollegiate Sports Through the history of human kind, there are evidences that females were excluded from almost everything, including sports. For example, in Greece there are evidences in the form of paintings and sculpture indicating that only males were allowed to participate in sports. Females were absent from these pictures because they were â€Å"unable† to play sports. Females were considered too fragile to play, too weak to stand up to the challenge; their definition of female was a â€Å"home wife.† They could not imagine female wrestling, fighting or participating in other sports because of their ideas of â€Å"women† as weak. This â€Å"image† of female as not being able to play sports was held through centuries until the twentieth century when the â€Å"Revolution† began to bring equality to females. Moreover, this â€Å"image† had bad effects on females’ lives, especially on female athletes, who were not wanted in sports because sports were only for males. Because females were not wanted, colleges and universities tried not to take female athletes and did not give female athletic scholarships. It resulted in decline of participation of females in sports. Females finally had enough of being treated as less than males and receiving smaller funds for athletic scholarships. Around the 1950’s, females started to protest against this unequal treatment in education, sports, and scholarship programs. They had to fight hard to receive any attention at all. In 1972, they were finally heard. Congress had enacted a new law, adding to the Educational Amendment Act, called Title IX. â€Å"Title IX of the Educational Amendment Act of 1972 prohibits discrimination on the basis of sex in any educational programs receiving federal financial assistance† (Kovacs 36). It states: No person in the United States Shall, on the basis of sex, be excluded from participating in, be denied the benefits of, or subjected to discrimination under any educational program or activity receiving federal financial assistance. (Title IX and Sex Discrimination) â€Å"Athletic are considered an integral part of an institution’s education program and are therefore covered by this law† (Equal Opportunities in Intercollegiate Athletics). Colleges and universities are required to provide opportunities for scholarships to both sexes. Those scholarships must be distributed proportionally to the rate of each sex. This does not mean that the number or amount of the scholarships has to be equal. However, the total amount must be substantially proportionate to the participation rates in athletic programs.

Frankenstein and Blade Runner

FRANKENSTEIN AND BLADE RUNNER EXAM NOTES Module A: Comparative study of texts and context. Comparative: compare and contrast Context: EVERYTHING, values and perspectives ANALYSING MOVIES Cinematographic Editing Frame composition Colour/group/shade Sound/ music Script/dialogue Acting qualities. EXPLAIN How frank represents the context of 1818 are both warnings to the evil of technology And blade runner context of 1982 BLADE RUNNER CONTEXT Ridley Scott is reflecting values by reacting against them.The biggest link that both are dealing with besides the excesses of sciences. -consumerism -industrialism topics being reflected in blade runner -greed -development at any cost Post war era, out of the Vietnam War . Computer industries booming and Ridley scott reflects this throughout the movie. Los Angeles is filled chosen as an example of industrialism. Economic rationalism- states that the economy dictates everything that happens in society.The Reagan& the Thatcher administration created a free economy whereby the government had less intervention with businesses this in turn created a great class distinction where the rich became richer and the poor became poorer. This idea is reflected in the movie by the idea of â€Å"onworld† and â€Å"offworld† lands where only the rich can afford to live away from the dead earth. Thatcherism- philosophy that anything that technologically advances is good anything that prohibits otherwise is bad.Industrialism – A dwarfing feeling is conveyed through the camera looking up towards the buildings and this further expresses the industrialism that has conquered this society. it is constantly repeated throughout the movie. Chose Los Angeles as a symbol of American industrialisation and technology, as a result of this you had the emerging environmental movement Both texts have a deep suspicion about the dangers of science and technology and what will happen if sci and tech will continue without control Consumerism- c oke, Atari etc are all symbols of consumerismFRANKENSTEINS CONTEXT 1818 – Frankenstein, romantic period 1780-1830 FOLLOWING age of enlightenment (rationalism) beginning of the industrial age: Head and heart knowledge Objectivity vs. subjectivity ENLIGHTENMENT- a period where reasoning and knowledge was central to authority (Rationalism) ROMANTICISM- a reaction to enlightenment, and the scientific rationalization of nature. The influences in context within Frankenstein (1818): â€Å"Learn from me, if not by my precepts, at least by my example†¦ who aspires to become greater than his nature will allow†- showing the dangers of enthusiasm which is common to enlightenment writers.In the 1831 edited version, language which sounds obsessive and uncontrollable is added. Frankenstein expresses more emotion and it reveals a more romantic spirit. The change in rhetoric was to show the dangers of romantic egotism and not to show the dangers of science. However this is irrelev ant in the sense that the change represents both sides to her context. The period of enlightenment and romanticism. INDUSTRIALSATION- all about urbanisations and the growth of big cities, before this was a close link to nature. Not so much about urbanisation but more about unlimited technology.Frankenstein has the rural theme with most characters out in the Alps chasing the monster etc. * Romanticism is the birth of a new sensibility, key elements is a growth in notions of individual consciousness- meaning being aware of individual consciousness and hence individual imagination. Having a man create a replicant human being and the amazing way frank wanted to learn the secret of life. Unaided with any assistance could learn language and everything else. – Very superior communication skills * Dangers of experimental science in which humanity is not its goal. The need for love and nurturing. * She clearly reflects aspects of her context, in that a small group of women such as her mother were the forerunners of the feminist movement. Starting to fight that group later be known as the suffragettes. She represents strong feminist views; it’s an analysis when men try to procreate without a woman. She is parodying expressed by the male romantics about the world of love and romance. Quite deliberate that the significant emotional attachments are with men: Frank- monster ClervalWalton WHAT CAN BE DISCUSSED A) CONCERN ABOUT SCEINCE AND DEVELOPMENT I) F + CONTEXT II) BR+ CONTEXT B) ONTOLOGICAL QUESTION WHAT IS A HUMAN BEING LIVING LONGER.
