Argumentative Sample Essay

Argumentative Sample EssayThere are plenty of people out there who write better, argumentative samples than most when they enter a room full of people. The argumentative sample essay is a great way to start. If you have never written an argumentative sample before, then it is time you did so.An argumentative sample can be in any genre, or even in the non-creative mode. Some like to do single sentences, while others prefer long paragraphs. The point is that they all involve the same basic process, which is to begin with your statement and create something around that statement.You can begin by writing a sentence or two, then work in a few sentences, and in a few more, then write out a complete paragraph. At the end of each of these paragraphs you should make an argument. Make sure that the final paragraph also has an argument, and another paragraph, or two, as an ending.Argumentative essays are a great way to test out the writing skills you have learned in the past. The best argumenta tive essays are typically about 70% non-creative, and the remaining 30% is mostly creative. What this means is that the average non-creative essay may contain the same paragraphs as the average creative essay, but will contain much more information, much more supporting ideas, and all of the critical thinking you have been working on in the meantime.When you write an argumentative essay, it is important to make sure that you have a strong argument, but not over do it. If you are in a room full of people who are well-educated, educated in their own right, then it is likely that you will come across as an opinionator who just happens to write well. Try to make your arguments are accurate and clear.It is good to always bring up certain thoughts, as this tends to make them seem real to the reader. Do not go too far into the topic, and make sure you are sticking to the facts. Don't leave out any important points, as you may find the other people there have had a different experience to y ou.Writing an argumentative essay is a good idea, especially if you are new to the subject. Most people like to see other people writing well, so it is worth your time to take a stab at it.

Truth And Nonviolence Will Never Be Destroyed Those Words Spoken By Ma

" Truth and nonviolence will never be destroyed" those words spoken by Mahatma Gandhi describe the true essence of his character. He was a man who unlike others decided to use nonviolence as a means of getting what he wanted. His different approach is what ultimately led to his rising popularity and strong success. Not only did Gandhi almost single-handedly free India and its five hundred million people from their long subjection to the British Empire, but he did so without raising an army, without firing a gun or taking a hostage, and without ever holding a political office. Mohandas Karamch and Gandhi was born on October 2, 1869, in Porbandar, near Bombay. Gandhi's family belonged to the merchant class called Vaisya. His father had been the Prime Minister of several small native states. At the young age of 13 Gandhi was married. The marriage was arranged with Kasturbai Makanji. At age 19 Gandhi set out to study abroad. He studied law at the University College in London. He found that there he was often looked down upon for being Indian. In 1981 Gandhi returned to India. At Natal he was the first so-called "colored" lawyer admitted to the Supreme Court. He then built a large practice. Gandhi soon became interested in the problems faced by fellow Indians who came to South Africa as laborers. He noticed how they were treated as inferiors. In 1894 he founded the Natal Indian Congress to agitate for Indian rights. In 1899, during the Boer War, he raised an ambulance corps and served the South African government. In 1906 Gandhi began his peaceful revolution. He announced that he would go to jail or even face death before he would obey an anti-Asian law. He never wavered in his unshakable belief in nonviolent protest and religious tolerance. Thousands of Indians joined him in the civil disobedience campaign. Twice Gandhi was imprisoned. He worked to reconcile all classes and religious sects, especially Hindus and Muslims. Gandhi became the international symbol of a free India. He lived a spiritual and ascetic life of prayer, fasting, and meditation. His union with his wife became, as he himself stated, that of brother and sister. Refusing earthly possessions, he wore the loincloth and shawl of the lowliest Indian and subsisted on vegetables, fruit juices, and goat's milk. Indians revered him as a saint and began tocall him Mahatma (great-souled), a title reserved for the greatest sages. Gandhi's advocacy of nonviolence, known as ahimsa (non-violence), was the expression of a way of life implicit in the Hindu religion. By the Indian pract ice of nonviolence, Gandhi held,Great Britain too would eventually consider violence useless and would leave India. When Muslim and Hindu compatriots committed acts of violence, whether against the British who ruled India, or against each other, he fasted until the fighting ceased. In 1919 he became a leader in the newly formed Indian National Congress political party. In 1920 he launched a noncooperation campaign against Britain, urging Indians to spin their own cotton and to boycott British goods, courts, and government. This led to his imprisonment from 1922 to 1924. In 1930, in protest of a salt tax Gandhi led thousands of Indians on a 200-mile march to the sea to make their own salt. he was then jailed again . This was called the "Salt March." In 1934 he retired as head of the party but remained its actual leader. Slowly Gandhi became to realize that that India would receive no real freedom as long as it remained in the British Empire. Gandhi's victory came in 1947 when India won independence. The victory was not a military victory, but a triumph of human will. The subcontinent split into tw o countries Hindu India and Muslim Pakistan. The last two months of his life were spent trying to end the appalling violence which ensued, leading him to fast to the brink of death, an act which finally quieted the riots. On Jan. 30, 1948, while on his way to prayer in Delhi, a Hindu, Nathuram Godse killed Gandhi. He had been maddened by Gandhi's efforts to reconcile Hindus and Muslims. Three shots from a small automatic pistol were which led to his final

Paul Henderson Essays - Politics And Sports, Free Essays

Paul Henderson Essays - Politics And Sports, Free Essays Paul Henderson For this project I chose as the quintessential Canadian, Paul Henderson. He is representative of the entire 1972 Team Canada. Before this famous series, it was assumed that Team Canada was unbeatable, but it soon became clear that Canada would be the underdogs and have to fight back. In the end, it was the little known player, Paul Henderson, who became the star and restored pride in the hearts of all Canadians. He is truly a "quintessential" Canadian. The 1972 Summit Series represented what was going to be a test of the best, to see who was the best "Hockey Country," Canada or the Soviet Union. Canada put their superstars up against the Soviet Union in an eight game Series where four games would be played in Canada and four in the Soviet Union. The games in Canada were played in Montreal, Toronto, Winnipeg and Vancouver while in the Soviet Union, they were all played in Moscow. The superstars for Canada included Bobby Orr, Ken Dryden, Tony and Phil Esposito, the Mahovolich brothers, Jean Ratelle, Yvon Cournoyer, Rod Gilbert, Dennis Hull, Brad Park and Pat Stapleton. Canada seemed to have a stacked team, but the Soviet Union was not about to quit. In fact, they dominated Team Canada in Canada taking two of four, losing one and tying one. Canada was embarrassed! Losing game one in Montreal 7-3 Canada had given the mental edge to the Soviet Union, but took it right back in game two in Toronto with a 4-1 win. Game three in Winnipeg was anyone's game, but neither team could get a definite lead and the final was 4-4. The series was now 1-1-1 for both teams. Convinced that they could not go to the Soviet Union trailing in the series, Canada needed a big game, but to no avail as they lost in Vancouver 5-3. Team Canada left the ice to the sound of boos. When the game was over, Phil Esposito said that they (Team Canada) were going out every night and playing their butt's off and all the selfish Canadian fans can do is boo them off the ice. He thought it was a disgrace. They were giving it 150 percent every night for one reason, because they loved their country. After that interview, 3,000 fanatic fans bought tickets to see Canada in Moscow. Down two games to one, Team Canada needed three out of four to win the Summit Series and prove that Canada was the best. Unfortunately, Canada lost the first game in the Soviet Union, and were down 3-1-1. Canada was in a state of desperation and that is when Paul Henderson stepped up. Game six in Moscow was the first of the three crucial games in Canadian history. Henderson, with one minute left in Game six, slipped the puck past a sprawling Vladislav Tretiak to get the 3-2 win. In game seven, Henderson was again the hero scoring the winning goal in a dramatic 4-3 finish. Game eight was THE biggest game in Team Canada history. This Summit Series started with Team Canada as the favorites, and that changed to the Soviet Union being the favorites and the Canadians being the underdogs. Now Game eight was here and Canadians all over the world were watching. With the series tied 3-3-1 Canada needed the win to prove they were the best. With the score deadlocked at 5 and one minute to go, Henderson made Pete Mahovlich get off the ice to let him on. With 40 seconds left, Cournoyer sent the puck ahead to a speeding Henderson. Henderson slipped and fell into the near boards. Esposito intercepted the clearing attempt by the Soviet Union and banged it towards Tretiak who made the save but left the rebound loose. Henderson, alone in front, took two whacks and on the second whack it went in to the right of Tretiak with only 34 seconds left on the clock. Canada had won the game. Paul Henderson, is the true Canadian hero and the perfect definition of the "Quintessential Canadian". Canadians all over the world were filled with a sense of pride at that moment in time. At that time, Hockey was the one thing that helped identify us as Canadians. It

Helen Keller who has had a significant influence on me Essay

Helen Keller who has had a significant influence on me - Essay Example To this very day, I can still remember how Keller struggled to find a way to overcome her disabilities. Her perseverance and passion truly touched me. I never thought that after another five years since kindergarten, I would be here in the United States, Helen Keller’s homeland. The first sight of the blue, cloudless sky was exhilarating. I am lucky, I thought to myself. This is the land of freedom and opportunity. However, I had not expected the difficulties that were lying ahead of me. My years in elementary and middle school were not so much enjoyable. I often had to take out my pocket-sized dictionary to grasp the meaning of unfamiliar words. Then people often made fun out of me. It was like trying to walk blindly in the dark. My parents on the other hand were very busy trying to make a living while I had to endure the harsh reality on my own. When people talked, I could not understand what they were saying. When I needed something, I could not open my mouth to ask simply because I did not know any English. Periodically, I borrowed short stories and interesting fictions to read so that I could improve my English skills. During that time, I could barely read a single page without spending more than ten minutes on it, trying to figure out each word I did not understand. I knew it would be extremely tedious to finish all the books, but in order to be successful, I had to master all these English phrases and words. Whenever I got bored and lost inspiration, I thought of Helen Keller and how she overcame her difficulties. I would keep going, no matter what it took to finish the book I would be reading. Seven years have passed since my journey to the U.S. Currently, I am enrolled at Stuyvesant High School, one of the most prestigious high schools in the United States. I am grateful that the individual who has had the single highest degree of influence on me is Helen Keller. I realize that I could never be where I am today had it not been

You have been appointed as a Marketing Consultant. In this role you are required to prepare a three-year marketing plan for Bonobos in the U.K market - Assignment Example But according to Dunn there was a gap for the fashion companies which took inputs but created something which a consumer can never do on its own. Thus the company to fill this gap established community driven platform where the customers through social media, purchase behaviour and commentary would affect the offerings made by the company. Eventually the company’s goal evolved from merely solving men pant problem to solving men shopping problem. Bonobos.com also provides access to products which are mad locally but lacked an optimal distribution and promotions; these items were termed as ‘Stuff’ which included belts, shoes and accessories. Bonobos used social media sites to promote its products which proved to a success for the company. These communities enabled Bonobos to markets its products and sell them without investing any dollar in traditional form of promotional techniques. Bonobos used Twitter, Facebook and the company’s blog to promote and gather inputs from the customers. In the first year of its business the company earned net revenue of $1.6million selling almost 30,000 pairs of pants. By 2009, Bonobos introduced trousers at a low price and Dunn expected the company to finish between $3.5millions to $4.5millions (Kinsey, 2009).

The Sewerage System In Malaysia Construction Essay

The Sewerage System In Malaysia Construction Essay Sewerage systems are one of the most important infrastructures in construction of residential, industrial or commercial project as it determines the quality of life enjoyed by a community. It consists of a network of underground sewer pipes, pump stations, sewage treatment plants and sludge treatment facilities. This system usually operates based on by gravity due to the slope of the pipe which reduces the high cost required for pumping. Sewers are further classified into a few categories, which depend on the type of wastewater that each of it carries. For example, storm sewers are designed to carry stormwater from roofs, paved areas, pavements and roads; industrial sewers are designed to carry wastewater generate from the industry; sanitary sewers are designed to carry the waste water from cooking and washing and the wastes from toilets. There is another type of sewer which is known as combined sewers. These types of sewers are designed to carry stormwater, industrial wastes, and domestic sewage. In Malaysia, many towns and cities use the separate sewer system. The wastewater is transported in separate pipes from storm sewers, industrial sewers and sanitary sewers. This system will not experience CSOs (Combine Sewer Overflows) which usually happen to combined sewer. The flooding will cause by stormwater only. Sewerage system is very important as it helps people to transport the wastes or sewage away from their places. Therefore, the system must be functioning well because improper functioning system will lead to pollution and contamination of various aspects of our surrounding which affect human life and health. Hence, regular maintenance must be done to the existing sewerage system and appropriate design must be applied to the new sewerage systems to ensure the sewerage systems are in good condition. The efficiency of the sewerage system is affected by the flow of the wastewater. In designing a sewerage system, the type and size of the pipe to be used must be able to accommodate the peak flow. The peak flow is based on the population equivalent which is a direct measurement of the population in an area. When designing the sewerage, there is a standard and criteria that should be followed. The standard code of practice for sewerage design in Malaysia (MS 1228:1991) was adopted from British Standard; BS 8005:1987. However, British Standard may not be as applicable to Malaysia due to the season and climate factor which have direct effect on the peak flow. This is the main reason of doing this research to find out whether the standard is suitable to be used in Malaysia. Problem Statement Any sewerage system will be designed to carry a certain amount of sewage based on the population equivalent (PE). In sewerage design, the per capita flow and the peak flow rate (Qpeak) are important parameters. Based on British Standard, the per capita flow is 225L/day/person and the peak flow factor, K is 4.7. However, a previous study indicated lower per capita flow and peak flow factor in the sewerage system in Malaysia although no conclusive results were obtained (Dayalan, 2007). A lower peak flow factor will result in smaller pipes which will incur lower cost. Therefore, further research is needed to study the suitability of current design criteria for sewerage system located in tropical climates. 1.3Research Objectives The objectives of the study are: To obtain flow data from pre-determined sewer tributary area. To evaluate the parameter in the peak flow factor equation for medium scale sewerage catchment system. To determine the relationship between population of an area to the peak flow of sewerage system. 1.4 Scope of Research To collect relevant information of sewerage design from selected literatures. To find out relevant formula provided in selected codes for sewerage design. To study the peak flow factor in sewer line that serve the PE value of 1000-10000. To measure flow characteristics by using flow meter with build-in sensor in manholes at Tropicana Indah. To compare the results obtained with the formula in the standard code. To make recommendation on the feasibility of the code formula to tropical climate. CHAPTER 2: LITERATURE REVIEW 2.1 Sewerage System in Malaysia The sewerage system is designed to collect wastewater or foul sewage generated from residential, industrial and commercial areas through sewer pipes and discharges it to the treatment plants or facilities to ensure the sewage is released to the natural water bodies in an appropriate condition and quality (Geoffrey, 2004). In Malaysia, sewerage systems range from simple toilet with little or no treatment provided to modern sewage treatment plants that treat the sewage to the desired quality accordance to environment standard. There are two main types of sewerage system in Malaysia. A premise sewerage system is either connected to a public sewage treatment plant or an individual septic tank. Indah Water Konsortium (IWK) is responsible to provide service and maintenance to public sewage treatment plants and all the underground pipes and also provide desludging services to individual septic tanks (Abd Aziz, 2006). IWK decided to divide the underground pipe into two sections, public pipe and private pipe (Figure 2.1) to make sure that all underground pipes operate without any problem. Public pipe is under the responsibility of IWK and the private pipe is under individual responsibility. An individual have to pay for the IWK services when the private pipe need for servicing. (Abd Aziz, 2006). http://www.usj23.com/planet_free/sewage_system/Sewage%20System.jpg Figure 2.1 Flow of wastewater from private pipe to public pipe (USJ 23 Residence 2.2 Transportation of Wastewater Wastewater is usually transported through sewer pipes that are connected to the sewer mains by clay, cast-iron, or polyvinyl chloride (PVC) pipes that range from 80-100mm diameter. The large sewer mains can be located about 1.8m deep or more than that along the centerline of a street or pathway. The small and large sewer pipes are made by different material, in which the smaller sewer pipes are made of clay, concrete, or asbestos cement, and the large sewer pipes are made of reinforced concrete construction. The flow of wastewater is different from water-supply system. The water supply is transported to each house by the application of pressure. However, the wastewater from each house is flows through sewer pipes by gravity. Therefore, the sewer pipe must laid on slope surface to allow the wastewater to flow at a velocity of at least 0.8m/s and not more than 4m/s. (MS1228:1991). If the wastewater flows at velocity lower than 0.8m/s, the solid material tends to settle in the pipe whic h will lead to blockage. Storm-water mains have similar structure as sanitary sewers but they have a much larger diameter than sanitary sewers. In certain places, the urban sewer mains are connected to interceptor sewers, which can then join to form a trunk line. The trunk line will then discharge the wastewater into the wastewater-treatment plant. This transportation process is shown in Figure 2.2. As the interceptors and trunk lines will carry the wastewater discharge from sewer main, they are usually made of brick or reinforced concrete which can carry more load than the other pipe. Sometimes, they are large enough for a truck to pass through them. (Norhan Abd Rahman et.al, 2007) http://techalive.mtu.edu/meec/module21/images/CombinedSewer.jpg Figure 2.2 Transportation of Wastewater (Michigan Environmental Education Curriculum, Wastewater Treatment) 2.3 Concept Theory In designing a sewerage pipe network, the pump stations and sewage treatment plants are required to carry and pump volumetric flow rate. The flow rates are usually measured in cubic meter per second (m3/s) and need to be calculated for both existing land use and for expected future development. There are two parameters that are used to calculate expected flow rates. One of the parameters is per capita flow. This per capita flow of 225L/person/day is an average daily flow, which means a person will produce 225 liters of sewage in a day. Another design parameter named population equivalent (PE) of a catchment can also be used to calculate the flow rate. PE is not a measure of population. However, it is used to measure the estimated number of people that use the sewage facilities. In residential areas, the PE is a direct measurement of the population in an area which is calculated as five per dwelling. The PE has a different method of measurement in commercial area. It is calculated fro m the floor area and this PE value is considered to be proportional to the number of people using a premise during the day which does not reflect the population living in an area. 2.4 Quantity for Wastewater 2.4.1 Tributary Area Tributary area is an area from where the wastewater is being transported to a particular sewer section. The types of activities in that area determine the quantity of wastewater being collected by a particular section. A survey has to be done when there is no information available on existing areas in order to determine the number and classification of persons and the types of industries. (Guyer, 2010) Table 2.1 shows the method of calculating the PE. Table 2.1 Equivalent Population, PE (MS1228:1991) No. Type of Premises/Establishment Population Equivalent (recommended) 1 Residential 5 per unit 2 Commercial: (include entertainment/recreational centres, restaurants, cafeteria, theatres) 3 per 100m gross area 3 School/Educational Institutions: Day schools/institutions 0.2 per student Full residential 1 per student Partial residential 0.2 per student for non-residential student and 1 per student for residential student 4 Hospitals 4 per bed 5 Hotels (with dining and laundry facilities) 4 per room 6 Factories (excluding process wastes) 0.3 per staff 7 Market (Wet Type) 3 per stall 8 Petrol kiosks/Service stations 18 per service bay 9 Bus terminal 4 per bus bay 2.4.2 Sanitary/Domestic Wastes 2.4.2.1 Contributing Population In designing the flow, the population to be used depends on the location of the sewer. The design population in a residential area is based on the number of houses served. However, the design population for an industrial area is the maximum number of staff ever employed. The design population for sewers that serve both residential and industrial areas include residents and non-residents. Designing of these sewers denote that no person should be counted more than once. Allowances should be made for future population changes caused by master planning projections and facility personnel requirements. (Guyer, 2010) 2.4.2.2 Average Daily Flow The average daily flow is counted by multiplying the population equivalent from resident and non-resident with the appropriate per capita flow and adding the two flows generated from both resident and non-resident. The average daily flow shows the total volume of waste generated over a 24-hour period. It cannot be used for wastes that were generated over shorter periods of 8, 10, 12 hours, etc. Therefore, it can only be used for designing sewers that generate wastewater over a 24-hour period (e.g. residential area). In Malaysia, the average daily flow for residential area is usually taken as 225L/person/day. In industrial areas, the average daily flow is taken as 115L/person/day as non-resident personnel and employees is working for 8-hour shifts. These quantities are usually used in designing wastewater treatment facilities. However, they are also used for sizing interceptors, trunk sewers and pumping stations serving large portions of the installation. (Guyer, 2010) 2.4.2.3 Average Hourly Flow Rate Average hourly flow rate is used for designing sewers that serve small areas of the installation (e.g. industrial area), where most of the wastewater is generated by non-residents or other short term occupants. The average hourly flow rate is counted based on the actual period of waste generation. For example, 1000 non-residents with an average daily flow of 115L/person/day would generate 115,000 liters in 8 hours which is equivalent to an average hourly flow rate of 14,375 L/h or 345,000 L/d. However, the average daily flow would still be 115,000 L/d. Therefore, the sewer must be designed hydraulically to carry 115,000 liters of waste in 8 hours instead of 24 hours (Guyer, 2010). If the sewer is designed to carry a waste of 115,000 liters in 24 hours, then the sewer pipe will not be able to transport the wastes as the actual volume of wastes generated is more than the design waste. This will lead to the blockage of sewer pipes and overflow in the toilet. 2.5 Design Wastewater Flow The design flow of wastewater must be determined for any section of a proposed sewer. The design flow is not only based on sanitary sewage; industrial flows, inflow and infiltration must also be taken into account. The following shows the equation to determine the peak flow factor and the factor to be considered in sewerage design. 2.5.1 Design Equations The peak flow required to design sewers, pumping station and treatment facilities are calculated by the following equation: Peak flow factor = 4.7 x p-0.11 p Estimated equivalent population, in thousand. The sewers are designed based on peak flow to ensure that the sewer pipes would be able to accommodate the wastewater generated at any time. 2.5.2 Factors Affecting Sewer Design In designing sewers, there are a few factors as stated in MS1228:1991 that must be taken into consideration: Economy in the design The sewers should be kept as short as possible and avoid unproductive lengths. Shallow rider sewers can be laid under highways having expensive foundations and surfaces to receive the local house connection, and to connect the riders at convenient points into the main sewers. Location of sewers The sewers should be placed within streets or right-of-way to ease the maintenance work. If topography dictates, the sewer is to be located within private properties, and provide adequate access for maintenance purposes. Location or the position of other existing or proposed service lines, building foundation, etc for maintenance purposes. A minimum at 3 m horizontal and 1m vertical separation from the water main should be provided to avoid the sewage from entering the water main. The impact of sewer construction and subsequent maintenance activities towards road users. Hydraulic Design The sewers should be laid at such gradients to produce adequate velocities to convey the solid matter. The gradient should produce a minimum velocity of not less than 0.8 m/s and a maximum velocity of not more than 4.0 m/s to avoid scouring of sewer by erosion action of suspended solid. Structural Design The depth of sewers must be adequate to accommodate the sewage from existing and future properties. The minimum depth should be 1.2 m. The minimum size of the sewer should be 200 mm in diameter in order to convey raw sewage. Straight alignment and uniform gradient between consecutive manholes should be laid for sewers of 600 mm or less in internal diameter while curves can be laid for sewers of larger than 600 mm internal diameter. Flexible type and watertight joints should be provided between sewers, sewer manhole or other appurtenance structure to avoid infiltration and breakage due to differential settlement. The foundation should be able to maintain the pipe in proper alignment and carry the weight of soil above the sewer and any other superimposed load. Service Connection The diameter of the connection must be adequate enough to prevent blockage problems. The sewer must have a minimum gradient of 2%. The minimum size of the connection should be 150 mm. Tee junction should be used to connect service connection to the main sewer. 2.5.2.1 Gravity Sewer Design Sewers are designed to convey the wastewater flows as required. Generally, it is not recommended to design the sewers for full flow, even at peak rates as the chances for problem arising are high. The flows that cover above 90% to 95% of full depths are considered unstable which may lead to sudden loss of carrying capacity with surcharging at manholes as shown in Figure 2.2 (Guyer, 2010). Surcharging means that the pipe that is designed to flow full or partly full, is now transporting the flow under pressure. When the flow exceeds the design capacity, there will be surcharge in the manholes (David and John, 2011). Besides that, large trunk and interceptor sewers laid on flat slopes experience less fluctuation in flow. If it is designed to flow full, the sewers may lack sufficient air space above the liquid for proper ventilation. Ventilation in sewer is important in preventing the buildup of explosive, corrosive or odorous gases, and for reducing the formation of hydrogen sulfide. Th us, the depth of design flow for trunk and interceptor sewers should not exceed 90% of full depth; laterals and main sewers, 80%; and building connections, 70%. Regardless of flow and depth, the minimum sizes of sewer pipes to be used are 150 mm for service connections and 200 mm for all other sewer types. The sewer pipes for service connections are usually smaller than 150 mm as they only convey liquids with little or no solids (e.g. condensate lines). A condensate line of more than 100 mm is recommended for most situations. Same design criteria as sanitary sewers can be applied to industrial application except pipe material that is resistant to the waste are to be specified. (Guyer, 2010) Figure 2.2 (a) Part-full pipe flow without surcharge (b) Pipe flow with surcharge (David and John, 2011) 2.6 Pipe Materials for Gravity Sewer There are many types of material which can be used for sewerage construction. However, the type of materials that we choose must depend on its life expectancy, previous local experience, roughness coefficient, structural strength and local availability. Table 2.2 shows the common materials that are suitable for sanitary sewers. Sewer pipes made by different material have different diameters and lengths. Table 2.2 Pipe Materials for Gravity Sewer Types of Pipe Material Length (m) Diameter (mm) Pipe Joints Vitrified clay pipe (VCP) 0.6 1.0 100 300 Flexible Reinforced concrete pipe 1.83 150 3000 Spigot socket type with rubber rings > 375mm diameter 3.05 Fabricated steel with sulphates resistance cement lining 9 100 1500 Spigot socket, flange and mechanical > 750mm diameter Welded joints Cast iron 3.66 Vary Flange and spigot socket type Asbestos cement pipe 4 100 600 Plastic pipe 6 110 630 Spigot end and socket type with rubber seals, jointing by flanges, welding and solvent cementing Other material CHAPTER 3: RESEARCH METHODOLOGY 3.1 Introduction In this research, a field work will be conducted to get the information that will be used to reach the objectives of this research. 3.2 Preliminary Works This is the initial works that has to be done before conducting the field work at site. It includes information gathering on the topic of sewerage design and self-study on similar and related topics in order to learn more. 3.2.1 Information Gathering A series of books, articles and online information has to be studied to obtain information on the topic of sewerage design. Sources for sewerage design mostly come from abroad. However, the information on the method to evaluate the design criteria is obtained from related research by a local university. 3.2.2 Standard Code of Practice for Design and Installation of Sewerage Systems (MS1228:1991) With the reference to this code book, the design criteria and the factors to be considered for sewerage design is obtained. The equations to calculate the peak flow which depend on the population equivalent are all available in this standard code of practice. 3.3 Site Work A site has been identified for the field work data collection. The location of this site is in Tropicana Indah. Approval is still pending from IWK for access to their manholes. 3.3.1 Flow Characteristics Measurement The flow characteristic of a section of sewerage pipe systems can be measured by using a flow meter. This flow meter is provided with sensor which will automatically record the flow, velocity and water height at a specific time interval, which in this case is 5 minutes. Once the measurement is completed, the data from the flow meter will be linked to a computer that has Flowlink4 software. This software would aid the plotting of graphs for the 3 parameters (flow, velocity and height) as well as transfer of data to other software. From the data, the maximum and minimum hourly flow rate can be obtained. The average flow rate can be used to calculate per capita flow. Flow per capita = Average daily flow (m3/day) / Total population equivalent (PE) = m3/day/person The evaluation of peak factor and per capita flow for sewerage can also be done through the data obtained from field experiment. The equations that are used for sewerage design are as follow: a. Peak flow factor = 4.7 ÃÆ'- p-0.11 b. Average daily flow = Flow per capita ÃÆ'- PE = m3/day c. Peak domestic flow = Peak flow factor ÃÆ'- Average daily flow = 4.7 ÃÆ'- p-0.11 ÃÆ'- Flow per capita ÃÆ'- PE = m3/day From MS 1228:1991, the p value is an estimated PE in thousands and the average flow per capita is 225 L/day/person.

The Connection Between AIDS and Homosexuality in Literature :: Gay, Lesbian and Bisexual Issues

     Ã‚  Ã‚   Disease permeates itself through all walks of life.   No one is unaffected by disease and the destruction it brings.   Families destroyed, communities torn apart, and societies in despair.   AIDS has taken its toll on the present society, and everyone is affected.   Much of the literature written on AIDS has tried to capture the disease and give it some form of meaning.   Where it comes from, how one contracts it, and the lifestyle of an AIDS victim many times is addressed in various novels and books.     Many of the authors that write on AIDS write with homosexual themes.   Homosexuality is prevalent in many books about AIDS and the question is why?   According to Les Wright many books with gay characters are written to counteract many of the assumptions made about AIDS and homosexuality.   The gay community is under attack, being invaded by both HIV virus and by the pathognomic counter-contagion of the social diseases of prejudice and hatred. In many narratives gay men respond with fantasies of military counter attack.   The historically disempowered, polluted homosexual turns the tables, identifying mainstream heterosexuals as pathognomically polluted and declaring them evil.   The Homosexuals claims victim status by virtue of the fascism of heterosexual society and casts his moral battle in political terms.   The outsider becomes hero; disease is rendered seemingly value-neutral.   Fire is fought with fire, and paranoia is attacked with paranoia (Wright, 55-57).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In one particular play that deals with the issue of AIDS and homosexuality, the writer shows characters that are different in background but very similar in nature.   The play, Angels in America, A Gay Fantasia on National Themes, written by Tony Kushner, is a tale about gay men dealing with societal values.   In dealing with these values they also encounter the issue of AIDS and how it impacts their lives and impacts the lives of the people around them.   There is a problem with character associating AIDS and its possible connection with homosexuality.   With the main characters, Roy Cohn, Joe Pitt, Louis Ironson, Prior Walter, and Harper Pitt, the reader visits the lives of these characters and learns how each person is affected by homosexuality and AIDS.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In the novel The Plague, by Albert Camus, the main character Dr. Rieux is talking to a colleague about the plague.   "Naturally, he said to Rieux, you know what it is... I saw some cases in Paris twenty years ago.
