Sustainability of Wastewater Treatment Systems

Question: Discuss about the Sustainability of Wastewater Treatment Systems. Answer: Introduction: The conventional wastewater solutions were not integrated, as these solutions make the recovery of resources difficult, including water, energy and nutrients. However, in contrast, new technologies are offering a range of alternative solutions for sustainable wastewater management. The key question in current context is whether it is possible to attain more sustainable urban water management by improvement of existing centralised systems or if it is crucial to implement new decentralized systems. The changed perspective for sustainability triggers the implementation of change. While switching over a decentralized aspect, close evaluation is needed into the sustainability of different systems in different situations (Balkema et al., 2002). As the changed process also has disadvantages, thus, before implementation, trade-offs should be considered crucially. In this paper, author summarizes multi-criteria assessment for sustainability of waste water treatment system. This method include s the use of sustainability indicators in multi objective optimisation, thereby aiding the community to select more suitable options. A number of sustainability indicators have been highlighted in the wastewater treatment systems. During the assessment phase, the sustainability indicators should be discussed. There are several sustainability indicators, based on which the suitable solutions are determined for a waste water management process. Four types of sustainability indicators have been discussed in this paper. The functional indicators help to determine the minimum technical requirement for the sustainability solution. For instance, effluent quality, adaptability, durability, reliability, maintenance required, robustness etc are functional indicator. The second one is economic indicators which are crucial during the section of the appropriate technology for the practical situation (Balkema et al., 2002). The commonly used indicators include the investment, operation, affordability, labour and effectiveness. The third indicator is environmental indicator. Environmental indicators are important for analyzing the resource utilization for addressing nutrients, water and energy. The indicators are resource ut ilization, biodiversity, lad fertility, land area and others, as indicated in several previous literatures. The fourth sustainability indicator is social-cultural indicator, which are hard to be quantified and thus, these two indicators are often misled. However, these two sustainability indicators have a significant role in technology implementation. The role of these indicators is especially highlighted, when the end-user is directly involved like in small scale onsite treatment, sanitation and water use. There is different use of these indictors in different circumstances (Balkema et al., 2002). For instance, in case of institutional requirements, different regulations and control mechanisms are required for different wastewater treatment. In case of acceptance, regarding waste management and sanitation, people from different culture would have different perspectives. In case of expertise, a notable level of expertise is required for installation and operation. All of these indicators are quantifiable, via cost calculation, measurement or enquiries. The indicators have both potential advantages and disadvantages. For instance, one potential advantage is stimulation of sustainable behaviour, in contrast, one disadvantage is acceptance, which may vary within different communities, due to diverse perspectives of community and technology users (Balkema et al., 2002). This paper analyzed the in-depth methodology of sustainability assessment in a system analysis with the use of multi-disciplinary set of sustainability indicators. Authors finally highlighted the crucial sustainability indicators; those include organic matter, cost, nutrient and land area. Reference Balkema, A. J., Preisig, H. A., Otterpohl, R., Lambert, F. J.

DUI Essay Essay Example

DUI Essay Essay Driving drunk is the act of operating a vehicle under the influence of alcohol, and a DUI is driving under the influence of other mind altering drugs. This doesnt only apply to cars and trucks but also planes, boats, farming vehicles, and even a horse buggy. Driving while intoxicated, also known as DWI is illegal almost everywhere in the united states. It is a crime in the state of New York, and can include penalties of losing your license, getting fines, and even Jail time. To determine how drunk you are, cops use a method called measuring someones BAC. BAC stands for blood alcohol content and any BAC reading . and higher is legally drunk in the state of New York. Nationally, 12. 8% of all drivers involved in fatal accidents during 2001 are known to have been intoxicated according to the BAC laws of their state. This number is based on a examination of the official records of each and every accident involving a fatality during that year in the US. It is based on factual evidence ra ther than on estimates or even guesses. The higher number (about 39%) commonly reported in the press refers to accidents in which there was believed to have been some alcohol consumed by anyone associated with the accident. For example, if a person who was believed to ave consumed any alcohol is stopped at a red light and is rear-ended by an inattentive completely sober driver, that accident is considered to be alcohol-related. Many factors contribute to blood alcohol content; such as the amount of alcohol you drink, how much you weigh, what youVe eaten since you drank, and how much time has passed. The best way to get sober before you drive is to wait. Your body absorbs alcohol at the rate of one drink per hour, so depending on how much you drink youll be waiting a long time.

That is why its dangerous for a erson under the influence to operate a car or truck. Every year thousands of people die due to drunk drivers, its a horrible statistic that leaves many familys sad, confused, and lost without their loved ones. Drinking and driving is something that should be taken very seriously. The BAC is different for drivers above and below 21 . If you are under aged then you should not be drinking alcohol in the first place. The BAC for a person under 21 is anything more than . 02. This is also referred to as the Zero Tolerance Law, anyone under 21 who drives with a . 02-. 07 BAC violates the law and can be fined with their icense suspended for 6 months. The penalties are in fact different depending on your age. When youre under 21 , you do not face Jail time and the fines are only around $100-$125. People 21 and older face prison and fines between $500 and $1000. Both people under 21 and over 21 face their license being suspended or revoked (below 21 suspended. Above 21- revoked. . Teens have many reasons for drinking and driving, like peer pressure, a lot of pressure is exerted on the non-drinker to drink with the group of friends. Most teenagers want to be accepted, but they make the wrong choices even thought they re familiar with D. W. I. Also like many adult drinkers, teens like to get together with a group and drink to relax and unwind. The teen years are an emotional time for many people because of situations at home, school, and dating for example. A lot of them feel alcohol offers a chance to unwind and get away from reality. Teenagers and pre- teenagers are very impressionable. If alcohol use and excessive drinking is treated lightly in the house, the teen can develop positive attitudes toward drinking. The constant barrage of ads in the newspapers, magazines and on T. V. portray drinking o be cool and a lot of fun for all those who are doing it. A lot of teens like to drink because it allows them to rebel against the law and their parents because its illegal. Its estimated that a dwi accident occurs every 32 minutes. An alcohol-related, fatal crash is one that was reported by a law enforcer and involved a driver or a non driver like a pedestrian with a blood alcohol concentration of 0. 01 grams per deciliter or greater. In 1997, 16,189 alcohol-related fatalities occurred, 38. 6% of the total fatalities for the year. Nearly one-third of the pedestrians 16 years or older who were killed by utomobiles were intoxicated, (had a BAC of 0. 01 g/dl). In 1997, of all fatal crashes that took place on weekdays involved alcohol; This percentage increased to 52% on weekends. For all crashes, the alcohol involvement on weekends was 12% and on weekdays, 5%. In 1996 and 1997, approximately 1. 5 million individuals were arrested for drunk or drugged driving. This is a ratio of one out of every 122 licensed vehicle operators. I agree with the laws, They are not too harsh, but at the same time they get the point across. If you are caught drunk driving you should pay the full price because ou are putting your own life and countless other lives on the line by making one bad decision. I think that if you are under 21 and have even a BAC of . 01, you should still get fined and your license revoked, because you shouldnt be drinking anyway. If your too immature to make the right decision and not drive drunk then your arent mature enough to operate a vehicle. I also think that you should go to Jail if your under 21 and get caught a 2nd time drunk driving. Drinking and driving again Just shows that you did not learn your lesson the first time, and now your going to pay the price.

History of Nursing Higher Education Essay Example | Topics and Well Written Essays - 1000 words

History of Nursing Higher Education - Essay Example Distance education has made it possible for those who wish to go into the nursing field to acquire their degrees-at least partially-and to attend classes in their field from home or from wherever there is an Internet connection. Nursing students do not need to live in the same area as the school in order to attend, which is definitely a huge change from traditional nursing education. The infusion of technology that has accompanied distance education has also brought other benefits to nursing education. Nursing students now have better equipment to practice on, such as more advanced patient simulators and patient care devices, and better resources from which to obtain knowledge, such as the Internet and vast online libraries. According to the American Association of Colleges of Nursing (2008, pg. 2), "Technological advances are increasing opportunities to improve dramatically the quality of and access to nursing education. Further, technology affords increased collaboration among nursing faculties in teaching, practice, and research. Careful use of technology in education may well enhance the profession's ability to educate nurses for practice, prepare future nurse educators, and advance nursing science in an era when the number of professional nurses, qualified nurse faculty and nurse researchers is well below national need. To take full advantage of technology in education, several factors need to be addressed by nursing and other leaders in education and health care institutions, as well as by external funders and policy makers." Distance education has also made it possible for people from all over the world to become nurses that might not have been able to otherwise. This means that it necessarily increases the multicultural aspects of the field. It opens the doors of opportunity into the field for those who want to become nurses, but may not have the time to study at a traditional institution. Many distance learners are working adults who are very concerned with aspects such as time management when it comes to advancing their careers (White, 2003). Nursing Shortage According to the American Association of Colleges of Nursing (2008): The United States is in the midst of a nursing shortage that is expected to intensify as baby boomers age and the need for health care grows. Compounding the problem is the fact that nursing colleges and universities across the country are struggling to expand enrollment levels to meet the rising demand for nursing care. The American Association of Colleges of Nursing (AACN) is concerned about the shortage of Registered Nurses (RNs) and is working with schools, policy makers, kindred organizations, and the media to bring attention to this health care crisis. AACN is working to enact legislation, identify strategies, and form collaborations to address the nursing shortage. A nursing shortage means that there is a serious need for recruitment into nursing schools. This can be challenging with biological scares such as MRSA, which will be discussed in the subsequent section of this assignment (Goold, 2006). MRSA According to Replidyne (2008, pg. 1), "Methicillin-resistant S. aureus (MRSA) is a type of Staphylococcus aureus resistant to certain

Prospective Analysis - Assignment Example The random walk model outlines that the stock price or earnings change have same distributions and are independent of each other thus past movements of stock price or earnings cannot be used to predict the future stock price movement. I disagree with John’s forecast strategy since the assumption of unchanging mean and variance is debatable. b. A merger or acquisition is will increase the future net income due to higher sales growth and more revenue generation from the acquisition. The merger or acquisition will reduce competition thus enhance the future net income. The best model that describes a better pattern of the earnings per share is the mean-reversion model since competition in the market will drive abnormal levels of profits to mean while reinvestment of the earnings will likely earn more levels of earnings. According to many analysts, the Earnings Factory is a ‘darling’ of the ASX. Its current market price $ 15 per share and its book value is $ 5 per share. Analysts forecast that the organisation’s book value will grow by 10 per cent per year indefinitely and the cost of equity is 15 per cent. The market’s expectation of the organisation’s long-term average ROE is calculated as follows; Companies with a high ROE can have a low PE ratio when the investors expect the firm will continue generate positive abnormal ROEs. The PE ratio is the market price per share divided by the earnings per

Why Germany Lost the World War Two Essay Example for Free

Why Germany Lost the World War Two Essay After WW I Germany had many economic and political problems that allowed Adolph Hitler to become ruler of Germany. After Hitler appointed himself chancellor he started rebuilding the German military. After years of no international response to breaking the Treaty of Versailles Germany attacked Poland. From 1939 to 1941 Germany had won many victories; however 1941 was a turning point in the war. By the end of 1941 Germany would continuously lose land to the allies with the exception of the Battle of the Bulge. The main reasons for Germanys defeat were that they were fighting the war in too many fronts, poor leadership and the invasion of Russia. Firstly, Germany is surrounded by nations capable of fighting Germany. Always has been that way. Oppositions were clever enough to realize Germany was strong enough to fight one mighty opponent, but might be in deep trouble if they had to fight two or more at the same time. Hitler realized that too. But he didnt have a choice. He tried to get what he wanted little by little. Until the Allies realized there was no end to it. Hitler then grabbed Poland in a deal with the USSR: they split the country. That gave him time to fight only in the west. This worked but didn’t include the conquest of Britain. Conquering England would be nice, but not vital. The USSR was seen highly dangerous at that time as well. So Hitler decided to strike first before Stalin did it and that made it a multiple front war. At first the Germans seemed to be winning, but fighting on three fronts (defense in the west, some forces in Africa and the major offensive against the USSR) was too much. The western front was an air war with Brittan. The eastern front was with the Soviet Union. A southern front could also be included in Italy and Africa. Germany had a war on multiple fronts just like in WW I. If Germany had invaded Brittan or never started a war with the Soviet Union there would have been only a single front to fight at one time. Therefore, Germany fighting on multiple fronts was definitely one of the reasons to why Germany was defeated in the World War2. Also if Italy was a stronger ally they could have stopped the allied invasion in the south. Having multiple fronts is not the only reason Germany lost the war, leadership also played a major role. Secondly, Adolf Hitler was not a very strong military commander. Hitler possessed many powerful leadership skills that won victories for Germany, but he often blundered into making military mistakes. Also, it must always be remembered that he was personally responsible for the death of tens of millions of people. It is difficult to call someone a great leader who causes such devastation among the nations of the world. His need to have personal operation of the German military crippled its effectiveness. Hitler was a superb politician however his military tactics and inability to listen to his generals caused many major battles to be lost. When invading France Hitler should have stopped the British Expeditionary Force from evacuating at Dunkirk. Hitler should have captured the BEF and continued his blitzkrieg right into Britain. Another tactical error was attacking Stalingrad not Moscow. He also wasted a large amount of resources on making the ME-262 a light bomber while it was already proven to the best fighter, even against other jet propelled planes. Adolf Hitler also wasted an immense amount of resources. As a result, Hitler’s poor military leadership certainly impacted their success in the Wold War 2. Thirdly, In 1942 Hitler made the vital mistake of spreading his forces out in Russia rather than concentrating them in a smaller area and because of this Germany failed to overwhelm and seize Stalingrad, this was to be the Start of Hitlers and Germanys downfall. This caused an extreme rise in Russian morale and from suddenly the war had reached a turning point and it looked like the Powerful Germans were nearing their defeat. After this particular mistake there was a sequence of events out of Hitlers control hammering the final nail into Germanys coffin. The Japanese sent a group of planes from the air force to bomb a small port in America named Pearl Harbour. This fired the Americans up so much so that they joined the war to defeat Hitler. Deciding to attack Russia was a bad idea, as well as declaring war on the US. Both of these countries could substantially out produce Germany. Although Germany took the initiative both times, they may have had little choice. The United States would have entered the war one way or another due to the fact that Britain was their closest ally, and they could not sit and watch them be destroyed by Germany. Russia was planning on entering the war a few months after Germany attacked her anyway. [This view that the Soviet Union was preparing a pre-emptive strike against Germany is not widely accepted]. Hence even thought Germany was a powerful country over all, there were many things to work on which brought this country down. Germany lost the war because of many reasons but the main three would be fighting the war in too many fronts, poor leadership and the invasion of Russia.
