What Happened free essay sample

I lay down looking at my ceiling,talking to myself, and notice how The value for something we once cherished can be lost and forgotten over time. Everyone has something to value. I value technology, history, and patience. Most people are not like me and I am aware of that, but in todays society we need to value our history a bit more for our futures sake. If value is something we base a majority of our standards on, then what is happening to the present and what will happen to the future generations. We do not even take the time to address that fact that times are changing, so where does that leave us? Media has influenced us in many ways, but the way we use this technology can bring our values to a lower standard.The thought that run through my head can be described in three simple words, lack of participation. We will write a custom essay sample on What Happened? or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Nowadays instead of hip new games that disappear within the year, we need to focus and involve ourselves around politics and news in order to stay aware, stay alert, and develop our nation in a more unifying way. We hold the power, yet we choose unwisely to act upon it by simple gestures such as not voting, not taking the time to understand the laws thats are being enforced, or even worse not being aware that this is our nation and we choose who runs it for us. Our values are being diminished because of the lack of participation. If you think about it, just about everything we have been exposed to has foreshadowed our future. For example, ever witness one of those coaches that lets his or her favorite players of the hook and not pushes them beyond their limits. How about those teachers that let you take the whole year on one assignment you end up losing after day one. It is people like these that have lost their value, so now they do not wish to pass it on. Now do you see the problem that as time passes on, things change, moral values lost, and history becomes your caregiver. In some cases, it is situations like these that develops the responsibility in yourself and others; however, being a student is recalicent I have to admit but what we lack is votive. A desire in going after the task we have yet to accomplish. Natural rights, Consent of governed, Limited government; does any of this ring a bell? All these concepts excited back in the 1800’s to 1900’s that basically state, â€Å"we are the best and we do the best for our country†.These concepts added value to our choices, but are now being forgotten due to the new ideas of technology, that on some occasions can be rendered useful to societies â€Å"younger crowd†with its use of social media allowing us, total access to the news on the streets from around the globe at anytime and anyplace. Media has its ups and downs, but its effecting the way we see our society and thats the problem.

Law Enforcement Deviance Essay Example | Topics and Well Written Essays - 1000 words

Law Enforcement Deviance - Essay Example The consequences of this deviance by the Los Angeles Police Department will be felt for many years as the public struggles to regain trust and the department struggles to regain credibility. Forms of police Deviance The use of excessive force and evidence planting are two forms of police deviance that are cited in the Rampart Independent Review. These acts of deviance are not exclusive to the Los Angeles Police Department, as there have been many occurrences nationwide regarding the use of unnecessary force and interfering with or planting evidence by police. Excessive use of force continues to be a major problem today. One of the most notorious cases of excessive use of force by officers was the case involving Rodney King. The Rodney King case not only contained excessive use of force, but also the falsifying of police reports (Mangan, 2000). The Los Angeles Police Department’s supervisors and officers downplayed the injuries to King as minor scrapes and bruises. The police o fficers involved in the beating reported that King confronted officers, resisted, and increased his level of resistance. A different story, however, is shown by the video. King is seen in a vulnerable position on his hands and knees as officers circle him and beat him repeatedly with their batons (Mangan, 2000). The two officers were found guilty, and the other two were acquitted. Police brutality has been a growing issue over the years, with police feeling like they are above the law and insinuating that criminals have no rights hence the brutal beating. There could be no possibly good reason to beat people especially when they are unarmed and handcuffed. Another law enforcement deviant behavior exposed by the Rampart Review is the abuse of drugs by law enforcement officers. In a particular example, a police officer accused several of his colleagues of taking drugs. In the Boston Globe was found that about 75 police officers did not pass any drug tests. For those that failed the te st, cocaine, heroin, ecstasy and marijuana were some of the drugs found in their tests. Of the 9354 people employed by the police force, 14 officers have failed drug tests since the year 2000 (Smalley, 2006). Reasons behind the deviant behavior by law enforcement officers Reasons cited in the Rampart Review about the law enforcers’ deviant behaviors are varied. One of the reasons given is the desire for the LAPD to get high marks for the declining crime statistics, possibly pushed by the officer’s leadership. Based on the claim that crime in Rampart area declined from about 1000 instances to fewer than 500 indicates this possibility. Another possible reason could be the lure of cash confiscated in drug busts. Normally, a police officer in Los Angeles earns an average of $42,000 (Indeed.com, 2009). Drug raids confiscate between tens and hundreds of thousands of dollars. The officers could be tempted to look for ways of keeping these funds for themselves. Once a police o fficer starts down slippery slope of theft and perjury, it is usually very difficult to find a firm footing. Many officers may find themselves continually trying cover their tracks until the point at which they hurt a civilian who may have too much information concerning their deviant behavior. Hence, the

Health Promotion Activity Essay Example | Topics and Well Written Essays - 1250 words

Health Promotion Activity - Essay Example Also the organization would have low employee turnover as the employees appreciate the organization’s concern about their wellbeing (Infinite Wellness Solutions, 2008) At present numerous health issues need to be addressed and selecting one among those is a challenging task. However, in recent times obesity has garnered the attention of everyone as this medical condition leads to many complications such as cardiac problems and diabetes. There have been a lot of studies which have demonstrated the prevalence of the condition in most of the families in America. Statistics reveal that in 2003-2004, the risk of overweight percentage in children and adolescents was 33.6% with the percentage of overweight children being 17.1%. This is a considerable increase when compared to the results of the year 1999-2000 (Ortiz, 2006). The prevalence of the condition has increased in the recent times due to the fast pace of life, increased consumption of junk food and lack of physical activity. However, this condition can be brought under control with lifestyle changes and support and would offer a lot of positive outcomes for both the employee and the organization. After identifying the problem that needs to be addressed the next step is to garner the support of the management. The organization should understand the significance of the health promotion activity and should be able to allot adequate funds for the implementation of the same. The next step would be to set goals for the activity and then form a health promotion team or a planning committee (Infinite Wellness Solutions, 2008). Goals need to be established in order to proceed and accomplish what you hope the program will do. It serves as a sort of framework identifying the current situation and the future course after the implementation of the program. A person would head the committee and would focus primarily on the activity, strategies for making the program work and to meet the

Technological Advancement: Effect on Intelligence

Technological Advancement: Effect on Intelligence The invention of Gutenbergs press was met with claims that the printing press, if not controlled, would lead to chaos and the dismemberment of European intellectual life (Shirky 1). Some people become anxious with new changes that throw out the restrictions that once was the norm. This, however, happens again and again throughout our history. Every increase in freedom to create or consume media, brings forecast of impending chaos and intellectual collapse. Our modern technology is changing the way our brains work. We no longer need to remember anything our tech does that for us. There seems to be a form of amnesia affecting us; the internet has changed the way we function. The way our brains have changed, from the use of the Web, is debated over and has yielded very different outcomes. Gary Small, a neuroscientist, professor, and author studied the effect that Internet searching had on the brain. Twenty-four participants were studied with half having no Internet search experience, the brains of the other half that regularly used the Internet showed an elevation in stimulation of the regions associated with complex reasoning and decision-making (qtd in Munro 4). The participants who were Internet novices had similar results in their frontal lobes after five days. Using technologies has influenced our brains, Small argues, the brain shifts towards and is energized by, new technological skills. This sounds good, however, as we rely more and more on our tech we become intellectually lazy (Munro, 2). Shirky states that the Net, in fact, restores reading and writing as central activities in our culture (3). The Net has greatly assisted people with their rese arch, having search results appear instantly instead of days of going through the library. Subsequently, not reading as we used to has had a price. Carr shares his struggle, Now my concentration often starts to drift . . . I get fidgety, lose the thread, begin looking for something else to do (1). The concentration we once had has changed, our brains forever altered. The Internet propels users from one place to another, making it difficult to concentrate on the task of simply reading. Carr admits, I cant read War and Peace anymore . . . even a blog post of more than three or four paragraphs is too much to absorb. I skim it (2). There is a new form of reading that has become more prominent in users of the Web, this skimming activity shows how our brains have been changed. A study was carried out by scientists at the University College London to see how our minds have changed when it comes to reading and thinking. During the five years of study two sites collected data on users behavior during visits to their sites, this produced results showing users bounced around the Net rarely re-visiting pages they previously had been to. It is thought that this style of reading promoted by the Net . . . may be weakening our capacity for the kind of deep reading . . . (Wolf qtd in Carr 2) that once was customary. The neural circuitry of our brains has been stu died when it comes to those readers that have an alphabet compared to those with ideograms as their written language, it revealed the brain of the ideogram learner was vastly different. The sections that govern cognitive functions as memory and the interpretation of visual and auditory stimuli (Carr 3) had the circuitry interlaced differently. Our concentration is now a struggle, what will the Internet propel us toward next? We were propelled into an age of technologies. These were supposed to save us time and labor. Munros opinion is that modern marvels are less labour-savers than brain-savers (1). The early technologies were meant to help us with the mundane daily task, automatic washing machines, dishwashers, drive-through car washes, but with these, it granted an excess of free time, the time we squandered with frivolous mind numbing activities. Todays advancements in technology have introduced us into an endless source of instant gratification. Take our cell phones, for example, they are now responsible for holding all our important information (i.e. numbers, addresses, meaningful dates) we no longer need to remember anything for ourselves. The connection is constant, Google can connect us to a source-any source-within a fraction of a second and with that why do we need to remember anything? Those things that were once etched into our brains, like our phone numbers, is now outsourced to our technolo gy. Robert Fitzgerald, associate dean at the University of Canberra says, There is indeed a dumb side to technology (qtd in Munro 2). He ponders if the searches his children complete yield something positive or if its a hit-and-miss. Is Google making us stupid? asked Carr (2). The answer is not so simple, but if not making us stupid, as such, Google seems to be making us intellectually lazy. Perhaps, our technologies will bring forth great positive changes or maybe leave us with digital amnesia (Harris 1). The Google Effect takes hold of so many of us, reaching our brains, inflicting its digital amnesia upon us (Harris 1). In 2011, an experiment conducted at Columbia and Harvard Universities brought theories that technology is reshaping the way we think and learn. Within our daily lives, some of us have come to heavily depend on Google to provide us with aid. From spell check to auto fill the decision we have made to use these electronic aids has [affected] our capacity to learn and execute daily tasks. No longer do we need to use our own memory, Google does it quicker and better, we get the answers faster and finish sooner. The information is recent but our comprehension of that information is lost. The abilities we traditionally [gained] through repetition and rote memorization are now impaired. This brain dump that occurs makes it difficult for an answer to be given, we must get back to someone because who needs to remember that? This dependency on Google is potentially harmful, all owing the tech to take over our minds, our work, making us inept to handle problems without it. The inflictions that The Google Effect has had on us needs to be turned around, a middle ground found, to ensure the future of technology and our analytical ability and intellectual capacity (2) remains intact Our tech will continue to grow and prosper, and continue to alter our minds, the way our brains think and learn. In the future, we will look back and find this tech to be distorted and the new tech will be more intuitive, more integrated, more intelligent (Munro 4). We can only wait and see if our intelligence ultimately might reveal itself in the smarts of those same technologies, (5). If we no longer dive deeper than the surface of information what will we be missing out on? What will we pass over and never come to know of? Carr describes a scene from Stanley Kubricks 2001: A Space Odyssey in his article Is Google Making Us Stupid? where the artificial intelligence is being disconnected, pleading for his life, feeling his memory slipping away, the human Dave continues to disconnect his memory circuits without a second thought (1). Showing a cold artificial side that technology could be inflicting on us, turning the tables and switching our roles. This new evolutionary journey will be full of struggle for we still have so far to go. This tech revolution has just begun and I can only hope we come out of it with our minds capable of our human emotion and not unfeeling as though we are an artificial intelligence. The world around us changes and so must we but lets hold on to our humanity, use our God-given abilities to expand our minds and lets not take the easier way, use our brains allowing it to grow and produce great works of art, literature, and advancements in all fields of study.

Change In The Things They Carried Essay examples -- Tim OBrien OBrien

Change In The Things They Carried a war novel by Tim O'Brien, we are told many short stories compiled to make a whole. I want to emphasis on the importance of the chapter "Sweetheart of the Song Tra Bong". In this chapter we are introduced to the character Mary Anne. She shows the changing power of Vietnam, that a sweet innocent young girl can come into this land and be forever consumed by her surroundings. The speaker show us this through character action, character description, dialogue and metaphor; this enhances the literary work by showing us that the soldiers will always be a part of Vietnam no matter how hard they try to get away from it. Mary Anne was a young sweet innocent girl unaffected by the war at first. The speaker shows us with character description from what she was wearing when she arrived. "This cute blonde just a kid, just barely out of high schoolÂ…white culottes and this sexy pink sweater."(O'Brien 90) Her "pink sweater" is a symbol for innocence, the color pink is associated with innocence; "barely out of high school" can also imply her innocence. The end of high school is the beginning of a new world for most. Thus meaning that she has her whole life in front of her. That she is just starting life. In this next quote you will see that she had the rest of her life planned out or so she thought. "Mary Anne Bell and Mark Fossie had been sweethearts since grammar school. From the sixth grade on they had known for a fact that they would get marriedÂ…that was the plan. They were very much in love, full of dreams, and in the ordinary flow of their lives the whole scenario might well have come true." (94) The speaker placed this quote to foreshadow Mary Anne's change. "Ordinary flow of their lives the whole sc... ... truth. This story enhances the literary work for it shows what can happen if you embrace a culture while surrounded by others who are just simply living off the land not being courteous to those who live on it. Her love for this land changed her forever, She is not the same sweet innocent Mary Anne who came off of that helicopter, and she is now one with Vietnam. This is a metaphor for what took place in the lives of soldiers, they go there expecting to just "hump" along but get consumed by the land. It forever changes them so that they will never be the same again. There minds are forever warped, they will go in as one person and leave another. The speaker uses Mary Anne as an accelerated version of a soldier's life to make a dramatic effect. She is to show how much a man changes after war, no matter how hard they try to deny it. The war has became a part of them.

Energy Situation In Pakistan Environmental Sciences Essay

Pakistan has been enduring from energy crisis since the last few old ages, which has earnestly affected its people. The power sector of Pakistan suffers from a serious deficit of up to 5000MW ( USAID Pakistan: Energy Efficiency and Capacity, 2012 ) .The spread between demand and supply has been invariably widening. Peoples are passing insomniac darks in summer. Load casting has become an issue of all the people. Where the rich people can afford UPS and generators, the hapless 1s can merely afford to bear the effects of power outage. Apart from personal jobs of the people, acute power outages have earnestly paralyzed the commercial and economic activities in the state and are making many hurdlings in development of the state. If we examine the present energy profile of Pakistan, it is run intoing its energy demands from different beginnings. Pakistan is bring forthing 48 per centum of its electricity from gas, 33 per centum from hydel power, 17 per centum from oil, two per centum from atomic and one per centum from coal. If we examine the figures, it is clear that Pakistan is underutilizing its natural resources to bring forth electricity. We have failed to work those resources that nature has bestowed upon us. We have non decently tapped our natural resources, even though we could hold met our energy crisis by making that and it is clip we look at this facet with unfastened eyes before the state of affairs gets wholly out of manus doing the hereafter coevalss to endure the rough effects.Energy used by Pakistan and spread between its demand and supply:Energy usage refers to utilize of primary energy before transmutation to other end-use fuels, which is equal to autochthonal production plus imports and sto ck alterations, minus exports and fuels supplied to ships and aircraft engaged in international conveyance ( TheWorldBank, 2012 ) . In footings of per capita ingestion Pakistan ranks comparatively low – 164 out of 217 states ( CIAWorldFactbook, 2003-2011 ) . Energy utilizations and national income per capita are straight related, because energy ingestion is critical to the development of an industrial economic system. In malice of being at the lower terminal of the word-wide energy devouring spectrum, Pakistan faces serious troubles in carry throughing its energy demands due to even lesser supply than the demand of energy. The Government estimates that energy demand will go on to turn during the following two decennaries, with Pakistan necessitating an estimated extra 35,000 MW of power coevals capacity by 2020. Based on the analysis, the expected new power coevals build out will be about 7,700 MW of extra capacity by 2020, go forthing a spread of over 27,000 MW. In a nutshel l, supply rate is neglecting to maintain in sync with the increasing demand rate owing to industrialisation, growing in agribusiness and services sectors, urbanisation, lifting per capita income and electrification of rural and urban countries.Possible solutions to the job of Energy crisis:In order to do up for the shortage and acquire the state out of a serious energy crisis that it is soon facing, both short-run and long-run policy enterprise are needed that enhance the state ‘s capacity to run into its demands. The possible solutions to the energy deficit can be divided into three chief types:1. Conservation of present energy beginningsThis includes cut downing inordinate ingestion of electricity and hence conveying down the demand for energy. This is short term step that can significantly cut down on the burden during peak demand periods by salvaging electricity. Conservation includes alterations in life style as good installing of energy efficient devices, edifice pattern s and electricity distribution and direction programs that optimize the supply when the demand is at its extremum.2. Importing more energyAnother option to assist increase the energy base of the state is depending on more imported fuel. At present Pakistan meets 75 % of its energy demands by domestic resources including gas, oil and hydroelectricity production. Merely 25 % energy demands are being managed through imports. Presently, programs are underway for importing gas from cardinal Asia. However, this scenario is besides certain to hold a negative impact on Pakistan ‘s balance of payments and hence a more reliable and sustainable beginning of energy is required.3. Investing in autochthonal renewable and non renewable energy beginningsThe 3rd option for Pakistan is developing its autochthonal capacity to use the untapped potency of its fuel militias. There is important room for development in all resources including oil, gas, coal and hydel – provided that the profic ient and commercial restraints associated with the public-service corporation of these resources are overcome.Coal as a new enterprise for Pakistan:Despite being a non-renewable energy beginning, surveies indicate that coal is traveling to play a really important function in the planetary energy scenario during the following two centuries. Harmonizing to an IEA study, coal usage is likely to turn from 41 % to 44 % , as a beginning for power coevals, by 2030 due to energy security and monetary value volatility. On the other manus, the portion of coal as a beginning of electricity bring forthing fuel in Pakistan bases at a meager 0.1 % in comparing to the universe norm of 41 % . Given the crisp rise in the oil monetary values in the international market every bit good as the fast depletion of Pakistan ‘s gas militias due to increased demand, it is imperative that Pakistan look towards alternate beginnings of energy including coal. There are a figure of advantages pointed out in favour of this development. These include: Abundance and security of supply. Energy denseness comparable to other beginnings of thermic power. Relatively easier to develop. The excavation and power production engineerings exist and merely an infrastructural development is required prior to their execution Handiness of clean coal engineerings and ways to minimise environmental jeopardies These are the grounds why Pakistan looks towards inventing a feasible scheme for the development of its coal militias at Thar.THARPARKAR COAL MINES:The majority of Pakistan ‘s autochthonal coal resources lie in Sindh. The largest modesty, 175 billion metric tons of lignite coal, is located in the Thar Desert of Sindh. Thar coal is yet to be developed for excavation and power coevals. The development of the Thar resources would supply. The electricity coevals potency of 100,000 MW based on estimated ingestion of 536 million metric tons of coal per twelvemonth, could be a important fuel resource used for proviso of coal base burden capacity in the system supplementing gas based capacity. Further, usage of Thar militias for power coevals would assist in cut downing inordinate trust on imported fuel thereby cut downing the force per unit area of balance of payments in the state. The entire estimated militias in Thar field including measured and conjectural are about 175 billion met ric tons. The existent mensural militias are 2.7 billion tones, the oil equivalent of which is 6.59 billion barrels. The oil equivalent of 175 billion metric tons of coal is about 427 billion barrels. The coal Fieldss cover a entire country of over 9000 sq.km in the Tharparkar desert. The field is covered by sand dunes that extend to an mean deepness of 80 metres. Below that is a bed of sandstone and siltstone which extends from 11m to 127m in thickness. Further underneath are variable sedimentations of clay rock resting on the Bara formation in which coal is embedded. The beds of coal scope in thickness from 0.20m to 22.81m ; the maximal thickness widening up to 36m in certain topographic point. The coal seam itself is present at a deepness of between 114-203m. The chief beginning of H2O in Thar is groundwater. The groundwater is present in three chief aquifers at changing deepnesss. The mean deepnesss are 50m, 120m and more than 200m which means that at least one aquifer is located in the coal bearing zone and will back up the mining/extraction processes ( GovernmentofSind, 2008 ) .Quality of CoalCoal quality and its contents have serious effects on the efficiency of the power w orkss in which it is used and besides on the grade of pollution that is created as a effect of electricity coevals. The coal found in Thar is lignite holding a lower warming value as compared to other types which makes it suited for electricity coevals. Its power coevals capacity is 10,289 MW. The brown coal at Thar has a heating value of 6200 – 11,000Btu/lb. Other of import constituents of the coal and their proportion are: Carbon ( 19.35-22 % ) , Ash ( 5.18-6.56 % ) , Moisture ( 43.24-49.01 % ) , Volatile affair ( 26.5-33.04 % ) and Sulphur ( 0.92-1.34 % ) .Production of electricity from coal:Some of the methods of production of electricity from coal are as follows:Pulverized Fuel ( PF ) engineering:In this procedure, coal is reduced to ticket pulverization signifier, stored and so transported by air to the burner as coal air mixture for burning. This method involves direct combustion of the coal to bring forth heat that is used to bring forth steam from H2O to turn conventional steam turbines. It is a straightforward technique but direct combustion of coal increases the external costs of energy by let go ofing nursery gases and other toxic oxides and fouling particulate affair into the ambiance in big sums. The efficiency of such a system is merely approximately 33 % .Fluidized Bed Combustion ( FBC ) engineering:Fluidized-bed burning ( FBC ) engineering is a type of burning procedure in which the solid coal is suspended on jets of air. In this manner, more efficient commixture of gas and solids occurs, taking t o more efficient heat transportation. The low temperature demand for burning reaction is one of the primary advantages because it reduces the formation of toxic azotic oxide. Additionally, FBC engineering causes inexpensive and easy remotion of sulfur dioxide during burning in comparing with the â€Å" stack scrubber † engineering. Furthermore, add-on of other solid fuels ( such as biomass ) along with the coal can besides be supported by FBC into the reaction mixture.ACoal Gasification ( CG ) technology/IGCC:IGCCA ( Integrated Gasification Combined-Cycle ) A with Carbon Capture and Storage ( CCS ) engineering allows coal to be used to bring forth power as flawlessly as natural gas. IGCC engineering has three basic constituents. In the gasification stage, heat, force per unit area, pure O and H2O are used to interrupt char down into its constituent parts and change over it into a clean man-made gas ( syngas ) .The syngas is cleaned before it can be converted into utility natural gas ( SNG ) which finally fuels the power turbines. Staying particulates are removed from the syngas in the particulate scrubber. Carbon monoxide is converted to carbon dioxide ( CO2 ) by adding steam in displacement vas. The gasification procedure makes it possible to capture most of the quicksilver, sulfurA and C dioxide ( CO2 ) in the syngas. The captured CO2A will be transported via grapevine for usage in enhanced oil recovery or storage in a saline geologic reservoir. The IGCC works so converts the syngas into utility natural gas ( SNG or methane ) , through a procedure called methanation. The SNG, which is comparatively high in energy content, powers two gas turbines. Excess heat contained in the fumes from those turbines so heats H2O to power a steam turbine. The higher energy content of the SNG ( as compared with syngas ) improves the efficiency of the power production. This combined rhythm ends up heightening the power works ‘s efficiency up to 60 % .Gasification is the engineering that most power workss are switching towards global and Thar Coal development is besides expected to construct IGCC workss for an environmental friendly procedure of coevals of electricity.The electricity to be produced from the coal gas would be about Rs. 4 per unit.Environmental Analysis:The beginnings of air pollution from coal based power workss fall include C emanations, particulate affair and other nursery gases and toxic oxides. Carbon emanations and ot her green house gases such as methane and N oxides are of import from the clime alteration perspective whereas toxic oxides and volatile particulate affair pose wellness jeopardies if the human population is exposed to certain degrees. In add-on to these quicksilver and other heavy metals are released which are linked with both neurological and developmental harm in worlds and other animate beings. Fly ash and underside ash are residues created when coal is burned at power workss. In the yesteryear, fly ash was released into the air through the smokestack, but now most of it is captured by pollution control devices, like scrubbers. The chief beginning of groundwater pollution is from the belowground processes that are carried out in the locality of aquifers in order to pull out coal or syngas. This affects the quality of groundwater and besides reduces its measure. It should be kept in head that land H2O is the lone beginning of H2O for the people of Thar. Dirt and Land pollution is a consequence of the excavation procedure itself as it may go forth the land non useable for agricultural or business by life because of drastic alterations in the surface or deposition of harmful affair in the dirt.Clean coal engineering and cut downing the harmful impacts of coal excavation:Clean coal technologyA is a aggregation of engineerings being developed to cut down the environmental impacts ofA coalA energy coevals. Some clean coal engineerings purify the coal before it burns. One type of coal readying is coal rinsing. It removes unwanted minerals by blending crushed coal with a liquid and leting the drosss to divide and settle. Other systems control the coal burn to minimise emanations of S dioxide, N oxides and particulates.A Wet scrubbers, or flue gas desulfurization systems, take S dioxide, a major cause of acid rain, by spraying flue gas with limestone and H2O. Low-NOx ( nitrogen oxide ) burnersA cut down the creative activity of N oxides by curtailing O and pull stringsing the burning process.A Electrostatic precipitatorsA take particulates that aggravate asthma and do respiratory complaints by bear downing atoms with an electrical field and so capturing them on aggregation home bases. GasificationA avoids firing coal wholly. With incorporate gasification combined rhythm ( IGCC ) systems, steam and hot pressurized air or O combine with coal in a reaction that forces C molecules apart. The resultingA syngas, a mixture of C monoxide and H, is so cleaned and burned in a gas turbine to do electricity. Carbon gaining control and storageA is the most promising clean coal engineering. In order to detect the most efficient and economical agencies ofA C gaining control, research workers have developed several engineerings. One of them, flue-gas separation is a technique thatA removes CO2 with a dissolver, strips off the CO2 with steam, and condenses the steam into a concentrated watercourse. The CO2A can so be sequestered, which puts CO2A into storage, perchance belowground, in such a manner that it will stay at that place for good. Flue gas separation besides renders commercially useable CO2. Another procedure, A oxy-fuel burning, burns the fuel in pure or enriched O to make a flue gas composed chiefly of CO2 and H2O which saves the energy required for dividing the CO2 from other flue gasses. A 3rd engineering, A pre-combustion gaining control, removes the CO2 before it ‘s burned as a portion of a gasification procedure. The CO2 removed can be stored in geologic or pelagic reser voirs from where it ca n't come in the ambiance. A DepletedA oilA or gas Fieldss and deep saline aquifers safely contain CO2 while deep belowground coal seams absorb it. A procedure calledA enhanced oil recoveryA already uses CO2 to keep force per unit area and better extraction in oil reservoirs. All signifiers of CO2 storage require careful readying and monitoring to avoid making environmental problemsA Reuse and recycling can besides cut down coal ‘s environmental impact. Land that was antecedently used for coal excavation can be reclaimed for utilizations like airdromes, landfills, and golf classs. Waste merchandises captured by scrubbers can be used to bring forth merchandises like cement and man-made gypsum for drywall.

The Nature and Causes of Obesity Essay Example

The Nature and Causes of Obesity Essay Example The Nature and Causes of Obesity Essay The Nature and Causes of Obesity Essay It is prevalent in our society, especially nowadays, that there are more and more people who become overweight and unhealthy, factors that may contribute to such is due to a person’s cost of living, lifestyle, personality, and attitude towards his or her food intake and everyday activities. This paper will discuss not only the above mentioned factors as a cause for obesity but it will explain the biological and medical cause of it. First, one can only draw conclusions unto what is the cause of obesity if he/she knows the exact definition of this. According to Myers (1), obesity is a state wherein there is excess body fat that has been accumulated and poses serious threat to the person’s health. This arises from too much energy intake and less metabolic rate and exercise. This could only mean that one of the factors that could lead to obesity is the person’s lifestyle. If the person has more calorie intake and less physical activity, he/she may lead to obesity. Aside from lack of exercise or physical activity, the person’s diet is also another factor. The reason why the input of calories is more rather than your physical activity is because of the food that you are eating. As probably already established, â€Å"there is a relative contribution of excess energy intake versus reduced energy expenditure to the obesity epidemic in the United States and in other countries has been the subject of much study and debate† (Caballero 2). Data shows that the US population has one of the highest rates of obesity in the world and it’s leaning cause is improper dietary intake. A large portion of this may be contributed by the increase in consumption of fast food and sweetened beverages (which accounts for almost 25 percent of daily calories in young adults). While other factors that could be causes of such are the following: low cost of energy-dense foods, increased consumption of prepared meals, and ample opportunities to eat throughout the day. Obesity can be a result of an interplay between genetic and environmental factor like many other diseases known to man. Obesity is found to be a major feature in rare genetic conditions like: Prader-Willi syndrome, Bardet-Biedl syndrome, MOMO syndrome, leptin receptor mutationss, congenital leptin deficiency, and melanocortin receptor mutations. A study was found indicating that 80% of the offspring of two obese parents were obese, would result in the same condition in contrast to less than 10% of the offspring of two parents who were of normal weight (Farooqi and ORahilly 710). On the other hand, obesity can be attributed to genetics but this still depends on the population that is examined. (Chakravarthy and Booth 4) The thrifty gene hypothesis states that certain ethnic groups may be more prone to obesity in an equivalent environment. Their ability to take advantage of rare periods of abundance by storing energy as fat would be advantageous during times of varying food availability, and individuals with greater adipose reserves would be more likely survive famine. This tendency to store fat, however, would be maladaptive in societies with stable food supplies. This is the presumed reason that Pima Indians, who evolved in a desert ecosystem, developed some of the highest rates of obesity when exposed to a Western lifestyle. Related to this, Some physical and mental illnesses that are used to treat them and also some pharmaceutical substances can increase the risk of obesity.   Some of the medical illnesses that can increase obesity risk are rare genetic syndromes and congenital or acquired conditions. Some of these are: hypothyroidism, Cushings syndrome, growth hormone deficiency and the eating disorders- binge eating disorder and night eating syndrome. Though these illnesses occur under obesity, obesity is still not considered as a psychiatric disorder. There are also some instances wherein medications may cause weight gain or changes in body composition. These medications include: insulin, sulfonylureas, thiazolidinediones, atypical antipsychotics, antidepressants, steroids, sulfonylureas, certain anticonvulsants (phenytoin and valproate), pizotifen, and some forms of hormonal contraception (Kolata 10). Lastly, while genetic influences are important in understanding obesity, they cannot explain the current dramatic increase seen within specific countries. Though it was already established that there are medical, psychological, and physical reasons for being obese, there are studies that show that there is a correlation between social class and Body Mass Index. There was a study found in 1989 that women under the high social class in the developed countries are less likely to be obese and in the developing countries, women, men and children from high social classes have higher rates of obesity. In the year 2007, an update of these study was made and found same relationships but weaker. It was said that the effects of globalization was the reason why there is a decrease in the strength of correlation. There are some explanations made regarding the association of BMI and social class. It was said that people in the developed countries can afford more nutritious food and are experiencin g a very high social pressure to remain slim. They also have more opportunities to do physical fitness. While in the developing countries, obesity patterns contribute to the high cost of living, high energy expenditure with physical labor and some cultural values. It was also said that a person’s thought about body mass may also play a role in obesity. A correlation in BMI that changes over time was also found between friends, siblings and spouses (Sobal and Stunkard 270).

Project and operations management - Essay Example Several external factors however are of concern when it comes to developing new products for the company (The Times 100, 1995). Such factors may include the need to develop low carbon products, increasing energy security and addressing the impacts on global warming. The research and development for the company operates on a model of push and pull where airs out to manufacturers their new developments so as to drive new technological innovations and the pull where the focus shifts towards market demands; what their customers want. The company’s major challenge is mainly technical or economic. With increasing complexity in technology, then the more people are needed by the company to overcome this challenge (The Times 100, 1995). But it has proved to be another challenge for the company to recruit more skilled workers that will be able to remain competent and enable ARM maintains its position in the market. Executive summary A project is typically a collaborative enterprise (Blu m, 1986). It usually involves research that is conducted frequently, involving a carefully planned research design that sets to achieve a given aim. Projects are social systems within organizations that are constituted by teams to accomplish given tasks within a given period of time (Spottydog, 2003). A project is usually conducted by school going and university students or by organizations. For school going students it may require the students to undertake fact finding and analysis from either secondary sources of information or from empirically gathering data (Yuan-Yi, 2001). The final output is usually in the form of a dissertation. The dissertation will contain sections of the whole projects inception, inquiry methods analysis, finding conclusions and most at times would require them to make suitable recommendations (Konecny, 2006). On the other hand for organizations it will consist of a temporary task that is undertaken in order to create products that are unique and satisfact ory services many at times in pursuit of satisfying the growing and changing demands of consumers such as the case of ARM mentioned above. (Morris Peter, 2007). Therefore the objectives of the given project will determine the target status at the end of the whole project. This will be necessary to achieve the planned benefits or the aims of the project. For example, in many countries engineering projects are specifically defined by legislation and requires that any engineering project should be carried out by only the registered engineers and companies for constructing buildings, industrial facilities, and transportation of infrastructure and such like other duties (Pinto, 2001). In such cases the project scope will be well defined within a contract from owners of the project and the engineering and construction companies. This kind of project has two major phases which are design and construction. Design phase involves drawing and calculations and the next which is the final phase will be to send the project plan to a developer who will do the construction work (Archibald, 1992). Project Brief A project in its self if a process and any process usually involves a set of interrelated actions and activities that have to be carried out in order to achieve a pre-specified result or services.

Annotated Bibliography on The Peloponessian War

On The Peloponessian War - Annotated Bibliography Example Flory Stewart is professor in classical history having developed interest in Latin while at a tender age. He taught at private boarding school in Athens, before returning to Yale to undertake his PhD. In this book, Flory recounts Thucydide’s hypothesis of the Peloponnesian War. By referring to the wars Greeks fighting each other, Athenians against the Spartans, the author gives a radical analysis of the factors that led to the war basing on accounts already presented by Thucydides. Notable in his argument is that the war must have arisen from the progressive rise of a powerful Athenian empire. The radical nature in which Flory uses Thucydide’s hypothesis seems to exemplify his theory even amidst critical remarks from other scholars. Generally, the book is important for any reader who would like to understand the ancient work by Thucydides in details. The classical nature of the book and simple language used makes it appropriate for a modern researcher. This book was written by Donald Kagan, who is an American historian at Yale University having specialized in ancient Greece. The four volume book gives vivid account of destructive war of Greeks against each other, and Athenians against the Spartans. It is a distinguished historical account meant for general readers, providing a new dimension to the examination of Western civilization. The author spent a great deal of time or re-examine the factors that instigated the conflict by reviewing both the ancient texts and accounts of modern scholars. The entire book seems to be informed by the question: Was the war inevitable, or could it have been avoided? Something unique about the author is that he courageously confronted and argued either in favour or against some historical figures, hence giving his view a balanced argumentative structure. Kagan particularly takes an issue with Thucydides’ view
