American Music Composers Essay Example | Topics and Well Written Essays - 2500 words

American Music Composers - Essay Example These learnings were then inculcated in the styles and forms apt to American culture and tradition to be able to compose "American classical music" (Sherrane 2007). This may be so, but the song and music heritage of the United States credits many American composers who have contributed to the musical history of the country. Among these composers is Charles Ives (1874-1954), hailed as the greatest American Composer by Time Magazine and Leonard Bernstein (Gutmann 2002). The History of American Classical Music is very rich and deep in its context. There are many contributors to American Classical music and they have indeed shaped what American music is today. These composers and musicians have worked hand in hand to establish music that has shaped how music is composed, played, performed, and listened to. The great American composers have sought to define music and contradict the form and style to be able to create new music that is apt for American culture and tradition. Born and raised in Danbury, Connecticut, Charles Edward Ives was a democrat who was described as fierce, optimistic, and idealistic in his ways of creating music that unified the voice of the American people with music derived from European classical music form and style (Swafford 1998). What emerged from the genius of Charles Ives was music that surpassed the expectations of man and his imagination. His music was in every essence bursting of American culture yet unique in its every note, tempo, and form. The primary influence and driving force of Charles Ives in his musical pursuit was his father, George, who was then leader of the Danbury Village Band. At five years old, he was found by his father drumming his fists on the piano and was hence given drum lessons (Swafford 1998). It was also his father from whom he received his first lessons in piano and other instruments. Until the maturation of his musical career, Charles Ives was infamous for "requiring a board to play the Concord Sonata" (Swafford 1998). This lead to what is now called the "tone clusters" (Swafford 1998). His interest in bi-tonal forms, polyrhythms and quotations was as well instilled by his father (G. Schirmer Inc. 2006). As his father loved exploring acoustics, dissonance, happenstance, and counterpoint, Ives was raised with an inquiring and transcendental approach to music (Gutmann 2002). As George Ives would always then say to him: "Don't pay too much attention to the sounds--for if you do, you may miss the music. You won't get a wild, heroic ride to heaven on pretty little sounds", Charles Ives sought to capture the emotion, the story, and the spirituality of life using music (Swafford 1998). Ives was thus driven to search for that heroic ride to heaven. What resulted from this was his creation of music so radical and original in its technique and style that it was surprisingly complex and very tricky to perform. In 1893, Ives left Danbury to study in Yale, New Haven. There, he underwent training under the supervision of Horation Parker, who was then famous for his high-Victorian oratorio Hora Novissima (Swafford 1998). It was in Yale that Ives created his First Symphony and First String Quartet, that he later subtitled "From the Salvation Army" in an attempt at a joke (Swafford 1998). It was during these four years in Yale that he got a better grasp of large scale forms, and his works then revealed a developing maturity

World Religions Report Assignment Example | Topics and Well Written Essays - 1500 words

World Religions Report - Assignment Example When looking at individual practices as well as the background of Buddhism, one is able to see specific doctrines and teachings that are applied to one’s life. This is furthered with comparisons of other religions, such as Christianity, the secondary religion investigated, to define the various roles and concepts that are formed with religious beliefs. Background of Buddhism Buddhism is an older religion with origins began in India, Burma and China, where it is still widely practiced. The main principle of Buddhism is to find the Middle Path which consists of the Four Noble Truths. The objective is to see how one can move through this lifetime and reach enlightenment of the spirit. This is followed by the Eightfold Path, which is eight different mechanics which one needs to reach the same enlightenment, or nirvana. Wisdom, morality, right views, resolve, speech, action, effort and mindfulness are the Eightfold Path to obtain enlightenment. The result is that one is able to go through a self – transformation on the intellectual, emotional and moral levels, which is what the Buddhists believe to help one move into enlightenment (Keown, 2009). The spread of Buddhism to the West has not only led to the different components of the main mechanics and teachings. This includes two sectors of Buddhism, including Theravada or Mahayana. The Theravada belief is the ancient belief, stating that the teachings are based on the original teachings for enlightenment. The Mahayana practice also has the main techniques and foundation from the ancient practices. However, this has moved into alternative perspectives and techniques based on practice, such as transformative beliefs, practical solutions for today’s needs and an expansion in the meditation techniques (Fowler, 1999). Interview Summary The interview that was conducted occurred after visiting a Buddhist temple at KSA. The outer area of the temple seems like a regular structure building that was used la ter as a temple. The landscaping has a large amount of greenery and is kept to create a sense of invitation in the building. The internal area of the building has the wheel of Buddhism in various areas, the statue of the laughing Buddha and various paintings and icons that are representative of the religion from the East. An assembly hall is located in the internal area as well as several rooms to the side for worship, meeting and to look into the Buddhist literature. These are each well decorated with the Buddhist symbols and signs, the Buddhist statue and other figurines from the East. A program was being held with the doctrines and beliefs that were associated with the temple, combined with several who were visiting. A Buddhist, by the name of Aaron, was found after the program that agreed to taking the interview and which had time to answer the questions that I required (see Appendix A). Aaron was in his mid – 40s and was a frequent member at the Buddhist temple outside o f his main job as a computer programmer. The information was recorded on an iPhone then transferred to paper later. The individual interviewed had been practicing Buddhism for over 15 years with the basis being in Christianity. The pull toward Buddhism began with the individual not feeling a strong enough basis toward the Christian beliefs while wanting more with the foundation of belief. The individual then decided to visit a Buddhist temple in the area to create a different understanding of religion. The origins of the practice are not practiced by family or relatives while creating an individual approach to the idea of reaching enlightenment. However, the individual also noted that practicing Buddhi

Life Cycle Analysis Of Paper Production Environmental Sciences Essay

Life Cycle Analysis Of Paper Production Environmental Sciences Essay During the typical life of a product, it will progress through 5 stages . At each stage there is interaction with the environment. In many cases the material processing and manufacture will occur in the same factory. The interaction between the product and the environment can be direct or indirect. For example, the pulping of the wood into paper will release emissions that are directly related to the paper. On the other hand, the transport of the paper will have an environmental impact from the emissions of the vehicle however this emission does not come directly from the paper. A Life Cycle Analysis (LCA) takes these emissions into account as well as other environmental impacts such as the destruction of habitat and can be used to quantify the environmental impact of a product from its original raw materials to its eventual fate (cradle to grave). The whole life cycle has to be considered, as the environmental impacts of different products will be greater at different parts of the c ycle. For example, paper will have a bigger environmental impact during the material extraction and material processing stages than it will for the use stage of its life cycle. However, an electrical item such as a washing machine will cause most of its environmental impact during its use stage because of its consumption of electricity, the majority of which are generated by the burning of fossil fuels. The life cycle must also consider the potential for the product to be recycled, remanufactured and reused. Reusing obviously has the lowest environmental impact as it requires less energy to convert the useless product into a usable product again. life cycle.gif Figure 1: The product life cycle showing the five phases and the potential to recycle, remanufacture and reuse products (Tarr, c. 2007) Paper is an essential product that the modern world relies upon. It is a highly functional product and is used to fulfil a variety of functions. It can be manufactured into many practical goods, with varying properties. It may be combustible or be made fire-resistant. It may be a carrier or a barrier or a filter. It may be tough enough to withstand acid or soft enough for a babyà ¢Ã¢â€š ¬Ã¢â€ž ¢s skin (Confederation of Paper Industries, 2010). Paper is a multipurpose commodity that can be used utilized to do anything from being printed on to deliver daily news to the masses, to create bank notes or even to make air and oil filters for cars. The worldwide consumption of paper in 2007 was about 300 million metric Tons (PaperOnWeb, c.2007). An LCA is a way of linking the inputs and outputs of any product to the environment and provides an insight into possible solutions to lower the environmental impacts of that product. A typical paper production process and each stageà ¢Ã¢â€š ¬Ã¢â€ž ¢s environmental impact are shown in figure 2 (below). recycling paper.jpg Figure 2: shows the stages in the life cycle of paper: the logging of wood in the forest and the environmental impact of this, its conversion to fibres, the processing of the fibres to make paper, the distribution of this paper to the consumers, the collection of waste paper, after which it is either recycled back into paper fibres or it is removed from the cycle and sent to incineration or landfill. Adapted from (Axel Springer, 1998) The paper industry uses a great deal resources and as waste paper is continually removed from the process, the paper industry is only viable if fresh fibres are constantly added. This means that trees have to be persistently cut down and removed from forests. This could lead to unwanted climate change due to their being less trees to absorb the CO2 and from the emissions from the manufacturing process and from the vehicles that are transporting the raw material. This wood could also have been used to generate energy, so removing it to create paper could lead to energy depletion. The trees used to produce paper should only be purchased from companies that will ensure that the trees are harvested and grown in a sustainable manner, as deforestation of local forests is unacceptable. If the trees were not harvested in a sustainable manner, and the trees were removed and not replaced the soil that would normally be held in place between the trees could be washed away when there is rainfall . During periods of exposure to the sun the soil would be dried out and the nutrients would be removed from it. This soil erosion would cause the land to become useless. Non-sustainable management of the forests will cause a disruption of the water cycle reducing the biodiversity of the forest. The paper industry is a very energy intensive one so carrying out an LCA on paper would allow us to see how much damage is being done to the environment by the paper industry. If the LCA shows that the paper industry is causing a significant environmental impact, it could cause a campaign for conservation. Goals The goals of this LCA were to assess environmental impacts of paper produced in Portugal, which is mainly exported and consumed in Germany, in order to discover what processes contribute the most to the environmental impacts. The environmental impacts being considered are the global warming over 100 years, acidification, eutrophication, non-renewable resource depletion and photochemical oxidant formation. The secondary aim of this LCA is to compare the environmental impacts of paper production, if the market was changed from German market to the Portuguese market. Limitations The LCA is limited by a few factors; firstly there is no data on the effectiveness of CO2 sequestration, so it was assumed that the CO2 released from renewable energy sources balanced the CO2 absorbed by forest growth. Secondly, even though fibres are recycled it is not clear how many times the original fibres can be recycled before they are too short to form a decent product, so it has been assumed that the paper is recycled 4 times at most before being sent to landfill or being incinerated. Thirdly, the materials that were present in less than 1% (in mass) in 1 tonne of paper of 80 g/m2 were ignored. Finally, the construction and maintenance of equipment, machinery and buildings were not included in the LCA. Inventory Analysis The first stage of an LCA is to carry out an inventory analysis. Here the overall life cycle of paper and the inputs required to make it are split up into smaller sections which are then broken down into individual processes and outputs which can be analysed. The life cycle was split into; forestry, paper production, distribution, final disposal in Germany and final disposal in Portugal. This is shown in figure 3 (below). Input: Raw Materials: Wood, Water and Chemicals Energy: Coal, Diesel and Electricity Forestry Paper production Distribution Final Disposal Germany: Landfilling 17% Incineration 8% Recycling 75% Final Disposal Portugal: Landfilling 53% Incineration 18% Recycling 25% Composting 4% Output: Usable Products Paper By-products e.g. wood for domestic purposes Output: Environmental Impacts Airborne Emissions Water Effluents Solid Wastes Figure 3: A diagram showing how the life cycle of paper was split into forestry, paper production, distribution, final disposal in Germany and final disposal in Portugal and how the inputs and output interact with each stage. Each stage was now separated into individual processes so that an inventory analysis could be carried out. This is summarised in figure 4 (below), which shows all the materials used and links them to the processes that occur. Stages Processes Forestry E. globulus forest Pine forest Paper Production Pulp production Chemical production Energy production in the grid Transport of wood to the pulp mills then to the paper mill Transport of chemicals Paper Distribution Transport of paper to Germany Paper distribution in Germany Paper distribution in Portugal Final Disposal in Germany Landfilling Incineration Recycling Energy production in the grid Transport of wastepaper from the user to the several disposal alternatives Final Disposal in Portugal Landfilling Incineration Composting Recycling Energy production in the grid Transport of wastepaper from the user to the several disposal alternatives Figure 4: A table of the processes involved at each stage of the paper life cycle, adapted from (Dias et al., 2007) To complete the inventory assessment data on the growth and harvesting of forests in Portugal would have to be found. It would also have to be known whether the paper mills in Portugal import trees from Scandinavia, as this would then change the size of the emissions generated from transporting the raw material to the paper mills. However, as the raw material is coming from Scandinavia there is a possibility that the emissions could be lower because the average emissions of CO2 from an articulated lorry carrying a load of 40 tonnes is 2.68 kg of CO2 per litre/km, where as a the emissions from a ship carrying the same amount of material would only be 0.4 kg of CO2 per litre/km (Davies, 2003). This means the material brought in by shipping can come from nearly 7 times the distance that it can if it is brought by road and still only have the same amount of overall emissions. A disadvantage of shipping raw material to Portugal is that the trees will still need to be transported from the port to the paper mill. This would not generate a significant amount more of emissions if the paper mill was located near a port. However, if the paper mill is located far from the port, the environmental impacts of transport will increase. The amount of pulp produced and the emissions that producing the paper pulp release would also have to be found. If the pulp is bleached to make it whiter, then there will be additional emissions with respect to wastewater. The paper making process is a very energy intensive one, so data would have to be found on the energy requirements of the paper making machinery and equipment. If the paper mill used some of its useful by-products to generate its own electricity, this would also have to be taken into account, as it may reduce the emissions generated by the plant as it will require less energy from non-renewable sources. However, it could cause an increase in the amount of particulate matter dispersed in the air from the paper mill. The environmental impact from the transport and distribution of the paper would have to be considered. As the paper is distributed in both Portugal and Germany, the environmental impacts of the distances involved in the distribution would have to be accounted for. The average distance for paper distribution in Portugal could be considered to be 200 km, for Germany this could be considered to be 2700 km. The environmental impacts of the final disposal of the paper in both Portugal and Germany have to be considered, as the policy for dealing with paper waste varies with country. In Germany, it is deemed that 5.8% of the paper produced is retained as archives. Seventy five percent of the paper that is discarded in Germany is recycled, 17% is landfilled and 8% is incinerated (Dias et al., 2007). In Portugal again it is assumed that 5.8% of the paper produced is retained as archives. Of the paper that is discarded 53% is landfilled, 25% is recycled, 18% is incinerated and 4% is composted (Dias et al., 2007). Using this information the environmental impacts of landfilling, incineration, composting and recycling could be calculated. The environmental impacts of the transport required to transfer the used paper to the recycling facilities would need to be determined in order to gain a more accurate representation of the environmental impact of the paper making process. Impact Assessment The impact assessment gauges the damage that will be done to the environment by the paper making process. The categories that could be considered are global warming over 100 years (GW), acidification (A), eutrophication (E), non-renewable resource depletion (NRRD), and photochemical oxidant formation (POF) (Dias et al., 2007). Figure 5 (below) shows the impact categories and factors that affect them. The factors that affect the impact categories are non-renewable CO2, CH4, NO2, emissions that are generated from renewable and non-renewable energy consumption, as well as chemical oxygen demand (COD) and adsorbable organic halogens (AOX). impacts of paper.png Figure 5: A table showing the impact categories and the parameters that affect each category (Dias et al., 2007) Using these weighting factors and the data collected in Dias et al. (2007), both an inventory analysis and an impact assessment were carried out. Each graph shows the analysis for both the German market and the analysis if the paper was to only be sold to the Portuguese market. Figure 6 (below) shows the results of the inventory analysis. Figure 7 (below) shows the results of the impact assessment. The negative values for various categories and stages of the life cycle reflect the parts of the process which have beneficial environmental impacts. Figure 6: A graph showing the results of the inventory analysis (G = German market, P = Portuguese market). The FU is the functional unit, which in this study is 1 tonne of paper (Dias et al., 2007). Inventory analysis results The area of the paper life cycle that uses the largest amount of renewable energy is the pulp production. However, the negative contribution is larger for Germany as more of the waste paper is recycled in Germany than in Portugal. This shows that the production of paper from recycled fibres consumes much less energy than the production of paper from fresh fibres. The majority of the non-renewable energy is consumed by the paper making process. The amount of non-renewable energy consumed by paper distribution is also greater for Germany than it is for Portugal due to the fact that the paper mills are located in Portugal so the paper has a large distance to travel before it is distributed throughout Germany. The non-renewable CO2 emissions are in similar proportions to the non-renewable energy consumption meaning that the paper production is the major contributor to non-renewable CO2 emissions. The paper production and distribution are the main sources of NOx emissions due to the energ y used from the national grid and the transportation of the paper. The SO2 emissions are mainly caused by the paper production stage of the life cycle, due to the energy production. On-site energy production provides a small negative contribution for NOx and SO2 emissions in Germany. The pulp production of the paper making process causes the largest contribution to COD emissions; however by recycling paper the final disposal stage can provide a slight negative contribution. Due to the chemicals used in the bleaching process of the pulping stage the AOX emissions are mainly created from the pulp production. Again from recycling the paper the final disposal stage can provide a negative input. Figure 7: A graph showing the results of the impact assessment (G = German market, P = Portuguese market) (Dias et al., 2007) Impact Assessment The most significant contributor to global warming in Germany is the paper production due to the high non-renewable energy usage and CO2 emissions. However in Portugal it is the final disposal that has the largest impact on global warming, as most of the paper waste goes to landfill which produces a lot of methane. As the paper production requires energy which produces high SO2 emissions, it is this part of the process that contributes most to acidification. The high COD and NOx emissions mean that the pulp production stage is the greatest contributor to eutrophication. A large portion of the eutrophication potential is down to the NOx emissions released due to the paper production stage. The electricity used during the paper production stage is the main contributor to the non-renewable resource depletion. Recycling the paper provides a positive impact to acidification and eutrophication, due to less material being sent to landfill and so fewer trees have to be removed from the forests. The amount of acidification, eutrophication and non-renewable resource depletion is greater for paper distribution in Germany due to the fact that the paper mills are located in Portugal so the paper has further to travel before it is distributed throughout Germany. The disposal of paper into landfill causes the release of CH4 which is a major contributor to photochemical oxidant formation. As Portugal sends more if its waste to landfill the impact of POF is greater. Conclusions The inventory analysis shows that Portugal consumes a larger amount of renewable energy and has higher emissions of SO2, COD, and AOX than Germany, this is due to the larger amount of paper sent to landfill. Therefore to change from the German market to the Portuguese market is less environmentally beneficial. However, the impact assessment shows that the acidification, eutrophication and NRRD are smaller for the Portuguese market due to the reduced transport required to distribute the paper. The pulp and paper production stages are major contributors to all the categories and environmental impacts due to the large energy requirements that are satisfied by both on-site energy production and consumption of electricity from the grid. From carrying out this LCA it has become apparent that the forestry stage does not provide any significant environmental impacts. Paper consumption in Germany is more damaging environmentally in categories in which the paper distribution stage has a consid erable input due to the large distance that has to be covered in order to distribute the paper. However, due to the smaller amount of recycling that occurs in Portugal, the global warming potential and photochemical oxidant formation are greater. This LCA has shown that the best area of the life cycle of paper to approach in order to reduce the environmental impact of paper manufacture is the pulp and paper production stages. The environmental impact could be reduced by more efficient treatment of flue gases and liquid effluents.

Changes in Class and the Labor Force within Society :: History Marx Communism Essays

Changes in Class and the Labor Force within Society Introduction: Though the Industrial Revolution changed the course of modern history, the consequences that accompanied it divided society. The radical change in the division of class and labor within society because of industrialization disgusted many who witnessed it, including Karl Marx. Their contempt for the new composition of class and labor led to intellectuals proposing improvements and reversing changes, through their writings to the masses, introduced by the Industrial Revolution. The Communist Manifesto and writings by Karl Marx and Frederick Engels are specific in their views on the class and labor structure in Europe and abroad. Class Structure Marx saw three classes emerge from Capitalist industrial society: labor power, ones who possessed the means of production, and those who owned the land. Their incomes consisting of wages, profit from industry, and rent collected from their land. Industry created by the Bourgeois revitalized society into two separate classes, the bourgeois and the proletariat. Communism offered the opposite, no division of labor or class. Marx believed that by eliminating personal gain from society, the class structure of Capitalism would be broken. Marx proposed the individual would receive from the greater society an equal amount of the shared commodities in comparison to his production of work benefiting the whole. There is an exchange of equal values. Each person receives equal share in the possessions of the whole for equal work. The bourgeois dissolves as personal profit is eliminated. Thus, granting rule over society to the proletariat. Class disappears because everyone is the sam e. Everyone is a worker. Free economic markets separates the means of production and the labor force. The result is the formation of an economically ruling class. The ruling class finds that labor equals only the means of production. Thus, the bourgeois pays the workers only the amount needed to sustain life. The proletariat is reduced to a life whose sole purpose is to find work. They only find work if their labor increases capital. Communism's Answer to Class Structure Communism offered the opposite, no division of labor or class. Marx believed that by eliminating personal gain from society, the class structure of Capitalism would be broken. Marx proposed the individual would receive from the greater society an equal amount of the shared commodities in comparison to his production of work benefiting the whole.

The Melting Pot

Is The United States of America the â€Å"melting pot† of the world? A melting pot is â€Å"a place where races, theories, etc. , are mixed. † (The Oxford Dictionary) Many immigrants come to the United States for the same basic reason: A better way of life. These same immigrants envision their dreams of success, freedom and happiness coming true. Without different cultures coming together learning from one another, many of today’s modern marvels would not exist. A good example of this is Marco Polo finding the different wonders like Gunpowder and exotic spices from his expeditions. Without the blending and discovers of the great people that came before us our world would not be as it is now especially America. Immigrants brings part of their homeland’s culture with them which, in time melts into other cultures. The basis of the U. S. was built on diversity, and is supported by statistic such as â€Å"Ten percent of America’s 281 million residents were born in other countries. (Swerdlow 12) Our country was founded and established under the principle that one man being different is yet equal by the same right. All of these cultures coming together are unique in their own ways but yet compatible. Many immigrants have enhanced the United States by their contributions as educators, authors, scientists, politicians. Alexander Graham Bell, scientist; Albert Einstein, scientist; and James Baldwin, author are examples, to name a few. It was not uncommon in the early 1900’s to find Ethnic individuals living all together in a community in some of the large metropolitan cities of the nation, but now while visiting any city in America you can often find dozens of different sets of people all living together in a community which allows individuals of our era tosee many different backgrounds, cultures, races, or people that may be the same as yourself or entirely different. I look at my own home as a result of the melting pot theory. My husband is Puerto Rican/Italian and I am German/English, and we both brought a lot of differences to the home from our cultures and beliefs. If we move on to the children we have with each other, but there are also blends of African American, and Jamaican. Having Stepchildren I find that through the social interaction of all the children in my home there is an ever evolving melting pot affect here due to the children learning from both sets of parents and then bring this lessons, ideas, and cultural information back and share it with the other children. Also, in our schools we have a multicultural mix of educators and students. During my time at Harrisburg Area Community College, I have met people from the Dominican Republic, Puerto Rico, Germany and Africa all here blending their heritage into our own. It was not so long ago in our nation’s history that there was a time where this evidence of the melting pot theory did not exist, and a good example with segregated schools. In 1964, President Lyndon Johnson, signed the Civil Rights Act which, one part of this comprehensive bill, allowed the integration of races in American schools. It was one of the largest changes in this nation’s history that brought two different cultures and ideas into the living room of all homes in the nation which contributed largely to the melting pot theory in America. We all have a common bond; we all want to educate ourselves to attain careers in which we can better sustain our families and ourselves. Part of this endeavor is the American dream to be successful. I have also been privileged to have Amish friends. They are of German decent and are not much different from us, what they call â€Å"English† people. This can be an example of the melting pot theory, because the Amish have a completely different set of values and lifestyle. They have yet to introduce their lifestyle on the â€Å"English† people here in Lancaster County, but the citizens of Lancaster County have greatly impacted their way of life. They conform to the modern world just like other cultures, and while conforming they have adapted to the use of common items of convenience such as cell phones, and electricity in their barns or homes. There is even Order of the Amish that live the same as you, and only dress in Amish attire for Church making this order the most prominent example of the Amish falling in the melting pot. They work hard to attain there goals, to be productive people and have freedom of religion. Isn’t this part of the American dream also? We are all in the â€Å"melting pot† because we are all blended with our family’s ancestry, ideas, beliefs, and cultures. Throughout the history of the world many nations have risen and fallen. All great nations such as Julius Cesar’s Roman Empire, Alexander’s Greek Empire, Genghis Kahn Asian Empire were all notorious for conquering the other nations of their time. With this in mind it is obviously assumed that all of these nations had one thing in common regardless of how they were founded, and that is they all had new culture and belief’s come into their nation which in turn blended into their own ideologies. In every aspect of our society in the United States we are not so different from past great nations, and becoming a melting pot was destined to happen. All the cultures, and the beliefs of all the citizens have been melted together to form new variants of the original cultures. This melting effect had affected our way life from education to careers to home. No matter if you are first generation Immigrant or a naturalized citizen of this nation we all share the dream of success.

During my time at Harrisburg Area Community College, I have met people from the Dominican Republic, Puerto Rico, Germany and Africa all here blending their heritage into our own. It was not so long ago in our nation’s history that there was a time where this evidence of the melting pot theory did not exist, and a good example with segregated schools. In 1964, President Lyndon Johnson, signed the Civil Rights Act which, one part of this comprehensive bill, allowed the integration of races in American schools. It was one of the largest changes in this nation’s history that brought two different cultures and ideas into the living room of all homes in the nation which contributed largely to the melting pot theory in America. We all have a common bond; we all want to educate ourselves to attain careers in which we can better sustain our families and ourselves. Part of this endeavor is the American dream to be successful. I have also been privileged to have Amish friends. They are of German decent and are not much different from us, what they call â€Å"English† people. This can be an example of the melting pot theory, because the Amish have a completely different set of values and lifestyle. They have yet to introduce their lifestyle on the â€Å"English† people here in Lancaster County, but the citizens of Lancaster County have greatly impacted their way of life. They conform to the modern world just like other cultures, and while conforming they have adapted to the use of common items of convenience such as cell phones, and electricity in their barns or homes. There is even Order of the Amish that live the same as you, and only dress in Amish attire for Church making this order the most prominent example of the Amish falling in the melting pot. They work hard to attain there goals, to be productive people and have freedom of religion. Isn’t this part of the American dream also? We are all in the â€Å"melting pot† because we are all blended with our family’s ancestry, ideas, beliefs, and cultures. Throughout the history of the world many nations have risen and fallen. All great nations such as Julius Cesar’s Roman Empire, Alexander’s Greek Empire, Genghis Kahn Asian Empire were all notorious for conquering the other nations of their time. With this in mind it is obviously assumed that all of these nations had one thing in common regardless of how they were founded, and that is they all had new culture and belief’s come into their nation which in turn blended into their own ideologies. In every aspect of our society in the United States we are not so different from past great nations, and becoming a melting pot was destined to happen. All the cultures, and the beliefs of all the citizens have been melted together to form new variants of the original cultures. This melting effect had affected our way life from education to careers to home. No matter if you are first generation Immigrant or a naturalized citizen of this nation we all share the dream of success.

Sleep Deprivation essays

Sleep Deprivation essays Sleep is one of the most important things a person does each day. It allows the body to rest and to replenish itself so that it is better able to serve its purpose of living. Yet, many people who don't have enough hours in the day to do everything have to cut out sleep before any other activity. This is especially true for teenagers, who are trying to get good grades, do extra curricular activities, work, and have a social life. Those are the things that lead to teenage sleep loss; the effects of this loss are devastating. School is one of the most important things of a young person's life, whether or not the teenager is willing to admit it. The teenager spends most of their time either in school or doing homework to further their education. The pressures of school are enormous. Stress is brought on with every project, experiment, and essay assigned to the student. They are forced to go through loads of work, trying to catch up to where they must be, all in order to receive good grades. On many occasions, these students will be up late studying, typing, reading, basically doing everything but sleeping. Sleep is put off so that more schoolwork can be fit into the day. Along with the pressure for good grades comes the pressure to participate in extra curricular activities such as plays, band, pompoms, clubs, and sports. Not only do teens have to keep up their grades, but they must also balance a calendar of school events. This can be difficult for many with heavy academic schedules. They will spend the afternoon in school, and then come home to eat dinner and begin their homework. Many will be up until three in the morning typing on their computers, only to go to sleep exhausted, and wake up three to four hours later to begin the day again, myself being one of them. With this little amount of sleep, many teenagers also feel the basic need for money and a steady income during their teen years because of pressure from parents an...

Michael John Anderson - The Craigslist Killer

Michael John Anderson - The Craigslist Killer Katherine Ann Olson was 24 years old and had recently graduated summa cum laude from St. Olaf College in Northfield, Minnesota. She had a degree in theater and Latin studies and was looking forward to going to Madrid to enter into a graduate theater program and getting her masters degree in Spanish. Many her age would have been afraid to venture so far from home, but Olson had a passion for traveling and had been to several places around the world. One time she had even worked as a juggler for a circus in Argentina. All of her previous travel adventures had been good experiences and she was looking forward to Madrid. In October 2007 Katherine spotted a babysitting job listed on Craigslist from a woman named Amy. The two exchanged emails and Katherine told her roommate that she found Amy strange, but had agreed to babysit her daughter on Thursday, from 9 a.m. until 2 p.m. On October 25, 2007, Olsen left for the babysitting job at Amys home. Investigation The following day, October 26, the Savage Police Department received a phone call that a discarded purse had been seen in the garbage at Warren Butler Park in Savage. Inside of the purse, the police found Olsens identification and contacted her roommate. The roommate told them about Olsens babysitting job and that he thought she was missing. Next, the police located Olsons vehicle at Kraemer Park Reserve. Olsons body was found in the trunk. She had been shot in the back and her ankles were bound with red twine. A garbage bag filled with bloody towels was also found. One of the towels had the name Anderson written in magic marker on it. Olsens cell phone was also inside the bag. Investigators were able to trace Amys email account to Michael John Anderson who lived with his parents in Savage. The police went to Andersons place of employment at the Minneapolis-St. Paul airport where he worked refueling jets. They told him that they were investigating a missing person and then took him to the police station for questioning. Once in custody, Anderson was read his Miranda rights and he agreed to talk to the officers. During the questioning, Anderson admitted that he used the online service, admitted he was present when Olson was killed and stated a friend of his thought it would be funny to kill Olson. The questioning stopped when Anderson requested an attorney. Evidence The Minnesota Bureau of Criminal Apprehension (BCA) examined Olsons body and the Anderson residence. The following is a list of evidence that was collected: A hair collected from Olsons body had matched Andersons DNA.Andersons fingerprint was found on the drawstring of the garbage bag in Warren Butler Park.The garbage bag contained a blue towel with blood that matched Olsons DNA profile.Olsons cell phone contained Andersons thumbprint.DNA analysis of a blood smear found at the bottom of the stairs in the Anderson residence matched Olsons DNA profile.A Ruger .357 Blackhawk revolver was found in Andersons parents bedroom was the same revolver used to shoot Olsen.A fired cartridge found in Andersons room underneath a pillow also came from the revolver.Andersons next door neighbor identified Olsens car as the one she saw parked in Andersons driveway for two hours on October 25, 2007. Computer Evidence Also found on Andersons computer were 67 postings on Craigslist from November 2006 to October 2007. Those posting included requests for female models and actresses, nude photos, a sexual encounter, babysitters, and car parts. Anderson posted an ad on October 22, 2007, requesting a babysitter for a 5-year-old girl. When Olson responded to the ad, Anderson replied posing as Amy and stated she needed someone to babysit her daughter. There were additional email exchanges between the two in reference to the job. Phone records showed that Olson called Andersons cell phone at 8:57 a.m. on October 25, and Anderson listened to the voice mail at 8:59 a.m. Anderson was charged with first-degree premeditated murder and second-degree intentional murder. Autopsy An autopsy revealed a gunshot wound to Olsons back, and injuries to Olsons knees, nose, and forehead. The medical examiner said Olson bled to death within 15 minutes from the time she was shot. There was no evidence of sexual assault. Aspergers Disorder Anderson pleaded not guilty by reason of mental illness, claiming to suffer from Aspergers disorder. The defense hired a psychologist and a psychiatrist who backed up the claim. Those suffering from Aspergers disorder have difficulties in social interaction, show few emotions, limited ability to feel empathy and are often clumsy. The court ordered a mental examination of Anderson by a forensic psychologist and a forensic psychiatrist, both who said that Anderson did not have Aspergers and was not mentally ill or mentally deficient. Scott County District Judge Mary Theisen ruled that expert testimony to the jury regarding Aspergers would not be allowed. Anderson later changed his plea to not guilty. The Trial During Andersons trial, defense attorney Alan Margoles depicted a lonely, socially inept young man who lived with his parents and never dated. He referred to the 19-year-old as a bizarre kid with no social skills who lived in an unreal world. Margoles went on to suggest that when Olsen turned Anderson down and tried to leave, he responded the way he did when he was playing video games - by pulling a gun on her which went off by mistake. He said the shooting was an accident caused by sympathetic response, which is when one hand flinches in response to the other hand. Margoles said he could have accidentally squeezed the trigger when he reached for his dog with his other hand. Margoles said Anderson was guilty only of second-degree manslaughter. That murder with premeditation or intent was never proven. Anderson did not testify at the trial. The Prosecution Chief Deputy County Attorney Ron Hocevar told the jury that Anderson shot Olson in the back because he was curious about death and what it would feel like to kill someone. Testimony was also given from inmates that said Anderson admitted to killing Olsen because he wanted to know what it felt like and that he did not plead insanity, because then I would have to pretend that Im sorry. Hocevar pointed out that Anderson never told the police that the shooting was an accident, or that he tripped over his dog, or that he just wanted a girl to come over to his house. Verdict The jury deliberated for five hours before returning the verdict. Anderson was found guilty of first-degree premeditated murder, second-degree intentional murder, and second-degree manslaughter-culpable negligence. Anderson showed no reaction or emotion when the verdict was read. Victim-Impact Statements During the victim-impact statements the parents of Katherine Olson, Nancy, and the Reverend Rolf Olson read from a journal that Katherine kept as a child. In it, she wrote about her dreams of one day winning an Oscar, of marrying a tall man with dark eyes and of having four children. Nancy Olson spoke of a reoccurring dream that she had been having since her daughter was found dead: She appeared to me as a 24-year-old, naked, with a bullet hole in her back and crawled into my lap, Nancy Olson said. I cradled her for a long time trying to protect her from the cruel world. Sentencing Michael Anderson declined to speak to the court. His attorney spoke for him saying Anderson had the deepest regrets for his actions. Directing her comments directly to Anderson, judge Mary Theisen said that she believed Olson was running for her life when Anderson shot Olson and that it was an act of cowardice. She made reference to Anderson stuffing Olsen in the car trunk and leaving her to die as a brutal, incomprehensible act. You have shown no remorse, no empathy, and I have no sympathy for you. She then handed down her sentence of life in prison without parole. Anderson has since been referred to as one of the many Craigslist Killers. Last Act of Parenting After the trial, Reverend Rolf Olson said the family was thankful for the outcome, but added, I’m just so sad we had to be here at all. We felt this was the last act of parenting for our daughter.

Can You Really Write an eBook in a Week

Can You Really Write an eBook in a Week If you could write a book every week, what would you write about? Is it even possible to write a book in a week? Browse Amazon, and you’ll find all kinds of writing books promising to teach you how to write a book in just a few days. I used to be cynical about these claims. I was a plodding writer. I believed you had to write slowly, otherwise you’d create shoddy work. The promise of writing a book in a week was hyperbole – or so I thought. Things began to change for me when I discovered that Isaac Asimov wrote over 500 books in his lifetime. On further examination, I found that other authors had equally prolific outputs. Belgian novelist Georges Simenon also wrote and published more than 500 books. Meanwhile the children’s writer Enid Blyton authored over 750 novels and story collections. Still I clung to my old beliefs. â€Å"Sure, they could do it,† I told myself. â€Å"But they had special gifts. For most writers, slow is normal.† I believe I was right that for most writers, slow is normal. But in all other respects, I was wrong. Fast writing continued to seem impossible to me until I had no choice in the matter. I’d been a professional blogger for several years, and then I got my first ebook client. I was thrilled. But the work came with a special request. My client needed the ebook finished within one week. Could I do it? I was terrified, but I wanted to give it a try. This was the opportunity I had been waiting for. Now, I could discover what I was capable of. That week, writing slowly was no longer an option. I got up early on Monday morning and began work. I started writing at 7.30 a.m., pushing myself to write as fast as I could. I poured my heart into every word. If anything, my writing seemed more vibrant for not being churned around my brain before being committed to the page. I finished the first draft I’d done it. I’d pushed through all my misconceptions and fears about writing. I’d learned I was capable of far more than I previously imagined possible. What’s more, I knew I’d created something good. My clients were delighted with my work. But what would readers think? Eventually, the first review came in. Five stars. I’d really done it! How much did I write that week? Ten thousand words. A relatively short book, but a respectable length ebook. Looking back, and knowing what’s possible for me now, 10,000 words doesn’t seem like a whole lot. But at the time, it seemed like a miracle. If you’ve never tried writing fast, I recommend seeing what you’re capable of. Challenge yourself to double your daily output. Even if what you write isn’t perfect, because you’ve written twice as much as usual, you’ll have an extra day free for editing. And chances are, you won’t need to do nearly as much editing as you think. You’ll only discover what’s possible So why not give fast writing a try today? I’d love to hear how you get on.

How Aggressive cartoons effect on children's behavior Annotated Bibliography

How Aggressive cartoons effect on children's behavior - Annotated Bibliography Example According to the people who are of the opinion that cartoon violence is very similar as most of the time harm is inflicted upon some of the characters. In a research carried out by Kirsch it was established that among both the adults and children long exposure to media violence has contributed to an increase of antisocial behavior.

Organization, timing and personal accountability Statement

Organization, timing and accountability - Personal Statement Example Lack of prioritizing will affect my career in business since I will not know when and where to concentrate my efforts. As such, this will be an obstacle in my career. Lack of priorities may make it hard for me to balance different aspects of my life. Be it social life, work life and even family life.

Outline and compare frequentist view of probability and subjective Essay

Outline and compare frequentist view of probability and subjective view of probability - Essay Example Although experts like Frank P. Ramsey have referred to the frequentist methods more specifically and directly, the topic of subjective analyses has also been an important focal point in several academic debates. Building at least outlines of the frequentist and subjective views is thus necessary before embarking on a more detailed comparative analysis. Frequentist View of Probability Frequentist view of probability is relatively more common and popular perspective o probabilistic studies. According to Professor Norman Fenton, probability theory can be regarded as the body of knowledge which facilitates formal reasoning on uncertain events. Furthermore, Fenton states: â€Å"The populist view of probability is the so-called frequentist approach whereby the probability P of an uncertain event A, written P(A), is defined by the frequency of that event based on previous observations. For example, in the UK 50.9% of all babies born are girls; suppose then that we are interested in the eve nt A: 'a randomly selected baby is a girl'. According to the frequentist approach P(A)=0.509.† (Fenton, paragraph 1) Frequentist probability is therefore generally dependent on data collection and manipulation of available sample spaces, where a number of specimens and/or trial/error events can be observed. Contextually, Ramsey has stated that probability is of essential significance not only in the sphere of logic but also in the physical and statistical sciences. Academics and researchers cannot be sure in advance that the most functional interpretation of probability in logic will help in understanding the physical sciences too. The frequentative nature of probabilistic studies can thus be assumed as to have special stress on practical trial and error methods typical to most of the scientific and statistical research works. Subjective View of Probability Subjective view pf probability can be thought of as more affiliated to the philosophical antiquity of the subject. The su bjective view takes into account even the individual perspective of the observer with relation to an array of uncertain events. According to Albert (Paragraphs 3-4): â€Å"A subjective probability reflects a person's opinion about the likelihood of an event. If our event is "Joe will get an A in this class", then my opinion about the likelihood of this event is probably different from Joe's opinion about this event. Probabilities are personal and they will differ between people.† Therefore, subjective view is aimed at exploring the theory of probability from the viewpoint of an observer. Hence, it can be regarded as to have relativistic implications rather than practical fact finding approach. Comparative Analysis Similarities As early as 1926, Frank P. Ramsey pointed out the dualistic nature of understanding the subject of probability as a whole. He pointed out that there are two interpretations, those are subjective and objective views, related to the science and art of pro babilistic enquiry. In furtherance with such an approach, Ramsey (188-189) writes: â€Å"And in a sense we may say that the two interpretations are the objective and subjective aspects of the same inner meaning, just as formal logic can be interpreted objectively as a body of tautology and subjectively as the laws of consistent thought.†

Managing and training a global workforce Essay Example | Topics and Well Written Essays - 750 words

Managing and training a global workforce - Essay Example Due to the importance of training companies have to device ways to become more effective at training a global workforce. The managing of employees internationally requires the use of sound management techniques. The business structure of a company affects the way employees are managed. Centralized and decentralized management systems function very differently. In a centralized management system all decisions are made at the top level, while in a decentralized system employees are also involved in the decision making (Blurit). Getting employees involved is a great way to instill confidence in the workers and to establish good labor relations. There are different factors that affect a company’s abilities to manage a global workforce. Four of those factors are cultural differences, language, currency differences, and regulatory variations (Gordon). The cultural differences among workforces affect a company’s ability to manage its workforce. Japanese culture is very male or iented. It would not be a good strategy for an American company to put an American woman in charge of a Japanese factory. In the United States women have equal employment opportunity, but there still exist a glass ceiling for women to get into managerial positions. During the next five years there will be more women at the top managerial positions of companies. ... Regulatory variations affect the way a company manages a global staff. The normal work week in France is 35 hours, while in the United States the normal work week is 40 hours (Itodt). The training of employees in global settings is extremely important. Due to the distance barriers companies that have headquarters in the United States or Europe have to adapt their strategies to train its staff located across the 200 countries in the world. A technique that can help multinational corporations implement training sessions faster and in a more efficient manner is the use of online training tools. An online training can be created customized to the needs of the global staff. Language barriers can be eliminated by creating the training in the native language of the population. One of the advantages of online training is the flexibility of implementation. Companies can choose to give the online lessons during working hours or to allow the employees to take the training sessions on their own time. Employees can assess the company’s intranet online to take the training. In order to be fair and to motivate employees to take the training session seriously companies can pay financial incentives upon successful completion of an online training taken at home. Due to issues associated with cultural factors another option companies can utilize to train its global workforce is to hire domestic consulting companies from the foreign location. For example a US company would hire a HR consulting specialist in China to train the employees from its Chinese operation. The use of this strategy can achieve better results because these firms have special insight into the cultural factors that motivate the employees from

Biology Pearson Textbook Homework Questions Essay Example for Free

Biology Pearson Textbook Homework Questions Essay a.There are several differences between RNA and DNA is that are key. DNA has deoxyribose sugar while RNA has ribose sugar. Secondly b.RNA is generally single stranded and not double stranded. Lastly RNA contains uracil in place of thymine. c.The three types of RNA are messenger RNA, transfer RNA, and ribosomal RNA. Messenger RNA is the â€Å"mirror image† of the DNA that encodes the amino acid sequence for the protein specified by the gene. The Transfer RNA transfers the amino acids to the ribosomes from coded messages. Ribosomal RNA helps build the proteins on the ribosome. d.The reason that so many RNA molecules are produced more than DNA molecules because you only have two copies of DNA in one cell. If only two proteins could be produced at a time it would take the cell a much longer time to do the functions that it needs to perform. 2. a.During transcription segments of DNA serve as templates to produce complementary RNA molecules. b.I think that the mRNA would not code properly for the correct protein so none of the functions could occur properly. No proteins could be made without the mRNA. 3.RNA George a.I am unspecialized and am very willing and capable to do any job. I can be used in the messenger, transfer, and building proteins areas of work. As a messenger I can encode the protein sequence that is given to me from the genes. As a â€Å"transferist† I can transfer the amino acids to the ribosomes. Finally as an rRNA I can assemble proteins. Please consider my application.

Case Study Of High Strength Concrete Construction Essay

Case Study Of High Strength Concrete Construction Essay In the text below I have tried my best and put in all of my efforts to create a document that might help other students even without any prior knowledge of the subject to understand the very important subject concrete with thorough understanding of the concrete. The text gives the basic knowledge of the lesser important concepts and has been written to depth for important and practical concepts. I have tried to create a document that shall be used to give lectures and cover the gap between a professor with in depth knowledge of the subject and a student who has just been introduced to the subject. I am also thankful to my professors and friends for their support in completing this work. I hope the document acts as a mode of information rather than being a jigsaw puzzle and fulfill all the requirements for the formal submission. Introduction: Civil engineering is the oldest and the most basic streams of engineering. When we think of civil engineering the first thing that comes to mind is cement and construction, when we come down to the more uses of civil engineering we think of concrete. Concrete is not such a simple thing as it may look down to a non construction related person, it is due to the fact that it has so many practical uses, more than any construction material that it has a specialization of its own. So the study of concrete is very helpful or may be considered the most necessary studies for a civil engineer. Nowadays the study of concrete is considered as the backbone of the construction industry. This subject has its own specializations available for study is such a vast subject that for a construction industry or company the success is decided by its concrete engineers. The modern industry of the todayà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s world relies completely on the construction of concrete structures. Concrete has experienced this great variety of use due to its marvelous properties that completely distinguish it from any of the rest of construction materials. The history of construction traces back to the times of Assyrians and Babylonians who first made the use of clay as a cementing material. The ancient forts and military buildings, the defense structures have witnessed a wide use of the concrete made of aggregates and lime as a binder. Construction of the pyramids in Egypt has also proved the use of lime and gypsum as a binder in the concrete works. The prominent scientists of the concrete study are Vitruvius who is believed to have the knowledge of chemistry of the cementitious lime. One of the remarkable ancient works is the pantheon, which consists of a dome spanning 43.43m and is made entirely of concrete. The Romans also used suitable cements made of suitable limestone burned in kiln or were mixtures of lime and puzzolanic materials (volcanic, ash, tuff) co mbining into a hard concrete. Vitruviusà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s work was followed by the researches made by M. Vicat of France. Joseph Aspedin of Yorkshire (U.K.) was the first to introduce Portland cement in 1824 formed by heating a mixture of limestone and finely divided clay in a furnace to a temperature high enough to drive off the carbonic acid gas. In 1845, Issac C. Johnson invented the cement by increasing the temperature at which the mixture of limestone and clay were burned to form clinker. This cement was the prototype of the modern Portland cement. From then onwards, a gradual improvement in the properties and qualities of cement has been made possible by researchers in U.S.A., U.K., France and Germany. What exactly is concrete: Concrete is a composite man-made material most widely used building material in the construction industry. It consists of a rationally chosen mixture of binding material such as lime or cement, well graded fine and coarse aggregates, water and admixtures (to produce concrete with special properties). In a concrete mix, cement and water form a paste or matrix which in addition to filling the voids of the fine aggregate, coats the surface of fine and coarse aggregates and binds them together. The matrix is usually 22-34% of the total volume. Freshly mixed concrete before set is known as wet or green concrete whereas after setting and hardening it is known as set or hardened concrete. The moulded concrete mix after sufficient curing becomes hard like stone due to chemical action between the water and binding material. It would be impossible to discuss all the aspects of this material in few pages and the discussion is confined to the general characteristics an d quality tests necessary for its use by civil engineers and architects. Most of the ancient structures and historical buildings had been constructed with lime concrete. With the advent of cement, the use of lime concrete has been confined to making bases for concrete foundations and roof terracing. The major factors responsible for wide usage of cement-concrete are mouldability, early hardening, high early compressive strength, development of desired properties with admixtures to be used in adverse situations, suitability for guniting, pumpability and durability. The simple reason for its extensive use in the construction of almost all civil engineering works is that the properties can be controlled within a wide range by using appropriate ingredients and by special mechanical, physical and chemical processing techniques Buildingsà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬from single storey to multistorey, bridges, piers, dams, weirs, retaining walls, liquid retaining structures, reservoirs chimneys, bins, silos, runways, pavements, shells, arches, railway sleepers are but a fe w examples of cement concrete applications. Concept of high strength concrete: Concrete due to its versatile properties is used for many heavy and medium or low cost constructions. So the concrete used in these works is not entirely same. Thus for more important and demanding works a concrete with higher strength is needed. This concrete can be given extra strength by various methods. Usually any concrete which falls in a grade over M65 is considered or called high strength concrete. This M65 signifies a compressive strength of 65N/mm2 after 28 days. This strength apart from other methods can be reached by REINFORCING the concrete with other materials of higher strength. Reinforcing means the mixing the concrete mix with other materials. The materials most commonly used are steel, bamboo, wire mesh, sticks etc. These materials provide those properties to the concrete that the concrete itself lacks. The concrete so reinforced becomes so strong that no other material can be compared to it. Also the strength to cost ratio of this is very less as compared to any other material available in the market. RCC and concrete: RCC and concrete are the same thing but for the fact that RCC has some reinforcement provided to the mix and the plain concrete is just a mix of cement sand and water along with aggregates. The reinforcement is placed where the structure has to be built and concrete is later put on it and both of these bond together to form a high strength concrete. The most common reinforcing material used is steel in the form of steel bars and wire mesh. So the wire mesh or the steel bars are easy to place and the main work then lies in properly preparing the concrete mix. So we shall now study the preparation of the concrete mix. Preparation of concrete: The concrete is fairly easy to manufacture. The preparation of concrete is a stepwise process. Its preparation involves storage of materials namely sand aggregate, cement, water. After that follows batching of materials which is a process of measurement of materials by different, convenient methods. Then falls the process of mixing which is a vital process; the most of properties depend on the mixing conditions and the type of mixing done. Mixing is the process of mixing the materials, batched before and preparing the final concrete mix or paste. The concrete so prepared is now needs to be transported to the site of use. This is done by using pans, wheel bar rows, transit mixers, chutes, bell conveyers, pumps, tower crane and hoists etc. Now that the concrete has been brought to the site it needs to be placed such that it gains maximum strength as easily as possible. So the placing is also a very vital process of the concreting operation. Now that the concre te has been placed we now have to make sure that no voids are left in the placed mix. Compacting the concrete mix makes sure that the concrete gains fullest of its strength. Then remains finishing of the concrete work done to make sure that it looks good aesthetically. Then the concrete needs to be cured to check the development of cracks and control the heat of hydration. The details of each of these processes are as follows: Storing of materials: Storing of materials is controlled so that the materials do not get deteriorated. The materials stored on sites are cement, aggregate, sand, water, steel and any other admixtures. The cement should be stored very carefully as the cement is the second most costly material after steel which is used in lesser quantities; cement easily attracts any moisture in the air and hardens and gets useless for the construction purpose. The cement should be stored in air tight rooms free of moisture and rodents. The bags of cement should be placed at least 30 cm apart from the walls and at least 20 cm above the floor level this is done by making a temporary platform of wood or other cheap material. The cement bags should be placed one over other to a maximum height of 1.5m. The cement bags should be used on the first in first out basis. These bags should be kept covered at all times with a suitable plastic cover. Then comes the aggregates, the aggregates should be so stored that these are distinguishly stored according to their size. These should either be kept completely moist or completely dry this helps to better understand the water cement ratio and provides a strict control over this vital ratio. Then comes sand, sand does not need much special attention while storing but sand so stored should be checked regularly for increase in the moisture content and hence bulking. The water used for adding to the cement or concrete is usually potable water and the water should be kept clean and free of any vegetation and any kind of visible materials and sand etc. Batching: The batching of materials is a simple process of measuring the quantity of the materials to be used for the concrete mix. This is done by two methods namely by weight and by volume. The materials while mixing need to be proportioned properly so that the desired strength and properties can be achieved. This has to be done strictly to ensure the desired properties. In the former category all of the ingredients are measured by weight. But this system has a drawback that the moisture content alters the weight of the materials and this has to be adjusted after experiments and mathematical calculations. The later uses the measuring the materials by volume and is less preferable to the above method. This is for the reason that the sand content varies greatly in volume by the moisture content. This variation is harder to account for accurate measurement. Mixing: The process of mixing of various ingredients of concrete in specified proportion is termed as mixing of concrete. Objectives of mixing: the quality and strength of concrete depends upon proper mixing. The object of mixing is to coat the surface all aggregate particles with cement paste and to obtain concrete of uniform color and required consistency. Methods of mixing: Hand mixing: the process of mixing the ingredients of concrete by manual labor is called hand mixing. It is adopted for small and unimportant and where quantity of concrete used is small. Hand mixing method requires more cement (10%) than machine mixing for obtaining the same strength of concrete. Machine mixing: The process of mixing the ingredients of concrete by a machine is called machine mixing. In case where a large quantity of concrete is to be produced, hand mixing becomes costly even if the labor is cheap. The machine maxing becomes essential. The concrete can thus be produced at a faster rate and at lesser cost. The quality of concrete by machine mixing is also better. Transportation of concrete: The process of carrying concrete mix from the place of mixing to the final position of deposition is called transportation of concrete. Transportation of concrete mix is very important because in transportation, time factor is involved. The mix has to be transported as soon as possible. Precautions in transportation: concrete should be transported as quickly as possible to the formwork within the initial setting time of cement. Efforts should be made to prevent segregation. Transportation cost should be as low as possible. The concrete mix should be protected from drying in hot weather and from rain during transportation. No water should be lost from the mix during transportation. Methods of transportation: -The following are the modes of transportation of concrete: Pans- in this method concrete is transported in iron pans manually. Wheel barrows- steel wheel barrows with 70L capacity with pneumatic tires are used for moderate distances. Truck mixers or tipping lorries- this is used for longer distances of travel. In this a truck or lorry having a mixer built into it is used to carry concrete. Other methods are: Chutes Belt conveyers Tower cranes Pumps Formwork: The temporary construction used as a mould for the structure for the structure in which the concrete is placed and in which it hardens is called formwork or shuttering. It includes all the surfaces in contact with concrete and all necessary supporting members. The part of formwork which consists of sheeting and its immediate supporting or stiffening members is called form. The part of formwork which supports the forms usually for a large structure is called false work. It is yet another important process for concreting. Compaction: Compaction of concrete is a process of eliminating the entrapped air in concrete and achieving maximum density. The importance should not be under estimated. The strength of concrete is reduced by about 40% by presence of only 5% voids. The compaction reduces voids to a minimum. The compaction is done by doing external work on the concrete. Finishing: finishing may be defined as the process adopted for obtaining a true, uniform concrete surface. The importance of finishing is inevitable. It is to keep the concrete surfaces free from undulations. The vibrating or hand tamping of a concrete leaves a slightly rough surface. Finishing of concrete surface is therefore important. The choice of concrete finishing depends upon the ultimate use of the component and desired aesthetic effect. Curing: The process off keeping the concrete moist to enable it to gain strength is called curing. It is name given to procedure used for prompting the hydration of cement. The concrete hardens because of hydration i.e. the chemical reaction between water and cement. This reaction depends on the presence of water. Although there is sufficient water at the time of mixing yet it is necessary to ensure that the water is retained to enable the chemical reaction to continue. Methods of curing: The various methods of curing are Shading of concrete work. Covering the concrete surface with gunny bags or hessians. Sprinkling of water. Ponding method. Membrane curing. Steam curing. Of these, ponding covering of concrete surface with gunny bags or hessians are the most commonly and very widely used. Proportioning of concrete mixes: Proportioning of a concrete mix means determining the relative amounts of materials required for batches of concrete of required strength. This process is generally called as design of mix. In proportioning a concrete mix, one has to choose suitable proportions of all the ingredients of concrete i.e. cement, aggregate and water so as to give concrete its desired properties both on the plastic as well as in hardened stage with the maximum economy. Grades of concrete: concrete id graded according to its compressive strength. As per IS 456:2000 the concrete mixes are designated into fifteen grades. The various grades of concrete are given in the table below: Group Designation Compressive Strength (N/mm2) Ordinary concrete M10 10 M15 15 M20 20 M25 25 Standard concrete M30 30 M35 35 M40 40 M45 45 M50 50 M55 55 M60 60 High strength concrete M65 65 M70 70 M75 75 M80 80 Concretes of compressive strength lesser than 20MPa may be used for lean concrete bases and simple foundations for masonry walls. Grades lower than M20 should not be used in reinforced concrete works. Grades lower than M30 should not be used in post tensioned prestressed concrete. Grades lower than M40 should not be used in pre tensioned prestressed concrete. There are two types of concretes based on the method of proportioning: Ordinary concrete (normal mix concrete) Controlled concrete (design mix concrete) Ordinary concrete (normal mix concrete): The concrete in which the proportions of cement, aggregates and water are determined by adopting nominal concrete mixes and no preliminary tests are performed is called ordinary concrete. It is only used when it is not possible to use controlled concrete. It may be used for grades M20 or lower if designed mix concrete cannot be used for some reasons. The proportions of the ingredients are specified by the engineer usually without testing the materials. There is no guarantee that a M20 nominal mix with adopted proportions (say 1:4:8) will have a 28 days cube strength of 20N/mm2. IS 456:2000 suggests the proportions of materials required for nominal mix concrete as shown in the table below: Grade of concrete Total quantity of dry aggregate per 50 kg of cement (kg) Proportions of fine aggregate to coarse aggregate by wt. Maximum quantity of water per 50kg of cement (liters) M10 480 Generally 1:2 but upper 34 M15 330 Limit is 1:1.5 and lower 32 M20 250 Limit is 1:1.25 30 Controlled concrete (design mix concrete): The concrete in which the proportions of cement, aggregate and water are determined by conducting preliminary tests for the design of mix is called controlled concrete. A design mix concrete is preferred over a nominal mix concrete for durability, strength and economy. Reinforced cement concrete: RCC or reinforced concrete cement is yet another type of high strength concrete. As explained when reinforcing materials of higher strength are added to the concrete it becomes reinforced cement concrete. The main feature of adding this reinforcement is that it makes the concrete very strong even in tension; otherwise in which concrete is very weak. This happens due to the bonding between reinforcing materials and the concrete mix. The concrete so prepared is used for many purposes such as piers, bridges, flyovers, dams, slabs, arches etc. The strength of same proportions of materials of concrete when reinforced yields more than twice the strength as it would otherwise. IS codes help us design structures of RCC by considering various norms and limits of safety and other factors. These tell us what extra provisions are needed to be made in certain conditions. The normally used reinforcements are steel bars which are explained in detail as under: Steel bars are available in the market in various sizes which are the measure of the diameter of the bar. These sizes range from 6 mm to 24 mm for general purpose. Other larger and specialized sizes are also available for special constructions. These bars are cast of steel formed by addition of about 1% of carbon content to iron while ità ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s manufacturing. This steel is very hard and is very ductile. Traces of other materials are also added to this steel to modify suitable properties. These bars are of two types based on the process of manufacturing or final properties: TMT- thermo mechanically treated bars Sal- ordinary ribbed bars. TMT: this is a product of the new age and has evolved as a result of scientific research over the years in the fields of metallurgy and other related field such as metallurgy and the properties of metals. These bars as the name suggests are mechanically treated to make stronger. These are first heated to a temp of 1400C (red hot) and then cooled suddenly which makes it stronger. Then these bars are also ribbed which makes them stronger at bonding. These bars are available in the market and are preferred over the other plain or ribbed or SAL bars. SAL: these are the traditional bars which were first tested by forming corrugations or ribs. The ribs on these are helical in shape. These are less strong than the other types of bars (TMT). These bars are manufactured from steel with 0.8-1.2% of carbon content in iron. These bars are brittle and less ductile. So these are nowadays moving out of market. These are not used in any of the engineering works. The cost of these is not considerably less than the TMT bars. These bars are available in sizes ranging from 8mm to 26mm. these bars make a weaker bond than TMT and should not be used for any important works. Design of RCC: RCC structures need quite a lot of mathematical analysis to be done before the values of final construction are received. The maximum amount of steel that can be added to the structures is 4% of the cross sectional area. The slabs and beams designed of RCC are categorized into two parts- singly reinforced structures and doubly reinforced structures. Singly reinforced structures are those in which the steel reinforcement is added to the lower side of the beam or the slab that bears tension. Doubly reinforced structures are those in which the steel reinforcement is added to both- upper and lower side of the structure for cases of variable tension and compression values; or extra strength is required for higher load values or when the dimensions of the member to be cast are limited due to some reason or other. These kinds of things make the RCC structures backbone of the construction industry. These RCC structures with steel are also very safe for shear and torsional forces too. Alterations of properties of concrete (Admixtures): The concrete has its certain properties that sometimes are needed to be changed, for this reasons other materials other than the basic ingredients are added to the concrete while mixing. These materials are called admixtures. These are categorized into several divisions: Accelerators Retarders Water-reducing admixtures Air-entraining admixtures Plasticizers Some common examples of admixtures are fly ashes, silica fume, rice husk ash, metakaolin. Now details of these types of admixtures Accelerators: Accelerators are the chemicals used to accelerate the setting and hardening of concrete. Accelerators are added to concrete to: Increase the rate of hydration and hence to increase the rate of strength development. Reduce the setting time. E.g. of accelerators- calcium chloride, triethenolamine etc. Retarding admixtures (Retarders): Retarders are the chemicals used to delay the setting and hardening of concrete. Retarders slow down the chemical process of hydration so that concrete remains plastic and workable for a longer time than a concrete without retarder. E.g. of retarders are sugar, calcium sulphate, skimmed milk, ammonium chloride, calcium borate, calcium tartarate, mucic acid etc. Water reducing admixtures: These are used to: Increase the workability of freshly mixed concrete without increasing water cement ratio. Maintain workability with reduced water cement ratio. Sugar in addition to acting as a retarder, improves the workability of concrete also. Carbohydrates and organic acids are other examples of water reducing admixtures. Air entraining agents: Air-entraining admixtures are used to entrain air in form of very small disconnected air bubbles in concrete. The air bubbles (approximately .01 to.25mm dia) act as flexible ball bearings and modify the properties of plastic concrete. It also modifies the properties of hardened concrete. Plasticizers: Plasticizing admixture is a substance which imparts very high workability with a large decrease in water content (at least 20%) for a given workability. It also permits the use of lower water cement ratio for the same workability. Materials used as plasticizers: Anionic substances such as lignosulphonates. Nonionic surfactants such as hydroxylated carboxylic acid. Other products such as carbohydrates. Calcium, sodium, and ammonium lignosulphonates are mostly used as plasticizers. Plasticizers are used in the amount of 0.1 to 4% by weight of cement. A 0.5% concentration of plasticizer by weight of cement can: Increase the 28 days compressive strength by 30% with 20% reduction in water cement ratio. Increase slump from 25 to 100mm. Require 15% less cement. Uses: these can be used where a high degree of workability is required in situations like: Deep beams. Column and beam junctions. Tremie concrete. Pumping of concrete. Thin walls of water retaining structures with high percentage of steel reinforcement. This was it about the case study of high strength concrete. I have tried my best to give the best approach possible to every aspect of any concept. Still humans will keep making mistakes so that they can learn from them. Thanks.
