Minimizing weather disruption in aviation: regard of Heathrow, British Airways and UK aviation system

Introduction More than any other mode of transportation, aviation is significantly affected by weather conditions including fog, thunderstorms, snowstorms, and wind as well as temperature and pressure extremes (Iyengar, 2002). Kulesa (2010) notes two major adverse effects of weather on aviation which are its impact on safety and efficiency of operation. The aviation industry must regularly deal with adverse types of weather to enhance safety while attempting to maintain integrity of flight schedules and to rein in on costs attendant to disruption, a significant budget item in aviation (Qualley, 2009). Weather disruptions at London’s Heathrow Airport in recent years have highlighted vulnerability in the industry. Of note was the adverse snow condition on December 18, 2010an exceptional event with unprecedented volume and speed of snow fall (AOA, 2013; DoT, 2013). This condition was compounded by capacity constraints and consequent lack of operational contingency since Heathrow operates at 9 9% capacity daily and the pre-Christmas period usually has high customer volumes (DoT, 2013; Seabury, 2012). The challenges of the day highlight prevalent problems and potential damage of weather-related disruption. A serious problem exists in the parallel forecast models run in the US and EU which give variations in weather forecasts. Conflicts are particularly often on parameters such as temperature of the day – which defines whether precipitation will fall as rain or snow (DoT, 2013; Qualley, 2009). On this day, weather forecasts and predictions were accurate and congruent and were received on time. Based on extensive experience on the part of British Airways (BA) and National Air Traffic Service (NATS), and in anticipation of greater challenges of disruption, a decision to cancel all BA flights between 1000 and 1700 was arrived at (BA, 2014; UK Parliament, 2011). There was however misjudgement among stakeholders on the severity of prediction and actual weather conditions. In the confusion, Heathrow claimed ‘business as usual’ while BA (its largest carrier) cancelled its schedule. Media reports of continued operations even after eventual closure of airport also undermined the decisive action taken by BA and thousands of passengers continued to turn up for cancelled flights creating chaos (UK Parliament, 2011). The command and control structure was not employed proactively or efficiently (Seabury, 2012). Overall, the airport failed to recover as quickly as it could have done and the impact of the day was extended unnecessarily. BA’s extensive and refined contingency plans for recovery following disruption were not replicated by Heathrow airport and were thus not useful (UK Parliament, 2011; Kulesa, 2010). A lack of forward planning and lack of shared operational experience about the most effective approach for return to efficient regular operations was evident when the airport re-opened (DoT, 2013). Major emphasis was put on the op ening of the runway without regard to the taxiway, apron and stand infrastructure which are also essential for efficient airport operation (Deloitte, 2013; UK Parliament, 2011). The ineffective approach caused many of the problems faced on re-opening and impeded return to normal operations. Eventually, a decision by Heathrow airport to invoke the Scarce Capacity Protocol (SCP) designed to ensure fair and proportionate allocation of access to take-off and landing slots for airlines was reached. This protocol was however overly conservative and difficult to enforce, hindered by policing issues (AOA, 2013; UK Parliament, 2011). Various UK airports have similarly been affected by weather conditions to varying degrees though recovery has usually been swift. A number of these airports remain open to receive long-haul diversions in times of disruption (DoT, 2013; Seabury, 2012). Although weather forecasting would add value to minimization of disruption, AOA, 2013 and Deloitte, 2013 disclos e that none among UK’s civilian airfields has a dedicated forecasting service based on site. Closure, delay, and/or cancellation have far reaching consequences beyond the inconvenience caused to customers which portends erosion of passenger goodwill and loss of future revenue (BA, 2014; Deloitte, 2013). Costs associated with weather disruption vary depending on contingency and elusive to pin down exactly. Direct costs derive from airline operations such as diversion, cancellation, delay or insurance and include listed costs such as: fuel, crew, time, and aircraft operating costs, lost passenger and cargo revenue, hotel accommodation and meals, ground-based employee overtime pay, insurance, etc. (Deloitte, 2013; Seabury, 2012). Disruption, particularly for hub airport operations given their extensive connectivity may have widespread effects affecting myriad flight schedules and airport operations in far flung areas. Seabury, 2012 and Deloitte, 2013 estimate that one diverted f light can cause 2 to 50 flight delays, while a cancelled flight can result in 15 to 20 delays. British Airways has more recently in 2013 and early 2014 been impacted by adverse weather in its operations at home and internationally (particularly the US) and affecting its global network (BA, 2014). In 2012, the airline also suffered mishaps on its Airbus fleet due to the freezing of pilot tubes which feed vital air speed data to on-board computers facilitating the autopilot mode. This led to two emergency landings evidence of the risk weather portends to safe flight linked to the potential damage in loss of life, property as well as repute (BA, 2014; FoE, 2013). This scenario lays out a representation of problems and damages consequent to weather disruption at Heathrow affecting BA and the entire UK aviation system. Steps to minimise the effect of bad weather and the ramifications of decisions to stakeholders Accurate weather forecasts are a priority for safety and efficiency in aviation. This is a primary focus area in order to minimize effects of weather disruption (FoE, 2013; Seabury, 2012)†¦ Accurate information derived from congruent forecasts from numerous agencies enables an effective prediction of the extent of disruption and therefore appropriate response. The use of varied and possibly conflicting forecasts was the probable cause of conflict in the case above creating problems and compounding the issue (Qualley, 2009; Iyengar, 2002). Adverse effects of weather on the industry can be avoided if only airlines and the entire industry work together to interpret such natural phenomena better. Various agencies – both state and private – should participate in accumulating reports and materials on weather patterns useful in the creation of referential databases. These can th en be updated and shared widely across the industry to minimize the impact of adverse events. Uniformity and congruence of information should be aspired to and costs associated with provision of weather information should be addressed (Kulesa, 2010; Qualley, 2009). Despite additional costs, the development of meteorological capacity on site in airports manned by employees or forecast vendors should be made mandatory. This strategy will negatively impact weather forecast contractors and vendors. Timely transmission of forecasts is also essential allowing sufficient lead time for appropriate preparation, and early response (FoE, 2013). Such include the efficient conduct of the intricacies of flight planning such as re-routing, rescheduling, load and fuel balancing, among others, as well as institution of mitigation measures. Open and extensive communication and consultation among various players is paramount for coordinated and effective response towards overall reduction of impact. T his can be achieved through efficient and proactive use of command and control structures and involvement of external entities such as the broadcast media transmitting vital information to customers. During response, focus should be on the entire airfield and mix of essential operations in an interdependent system (Kulesa, 2010). Development of comprehensive and extensive protocols and contingency planning should be undertaken to facilitate response to disruption (Deloitte, 2013; DoT, 2013). These should entail forward planning, strategies and methods to govern operations, as well as effective business continuity plans to mitigate risks to the extent possible. Despite prohibitive costs, use of intricate computer programs in planning and response should be encouraged. Existing policies, protocols and measures should be realigned and restructured for better effectiveness and enforcement mechanisms should be instituted to ensure compliance (Seabury, 2012; UK Parliament, 2011). On-groun d mitigation measures such as de-icing and ploughing of snow should be made mandatory and part of essential procedure. Such measures may not sit well with independent industry players but should be enforced. At the operational level, measures to protect reputation and consequently the potential loss of business from inconvenienced customers should be instituted (Deloitte, 2013). Customer support programs and response centres undertaking such tasks as rebooking, refunds processing, and provision of information are thus essential. Airlines should also create alliances and agreements activated in times of disruption to enable support for affected players and entities (Seabury, 2012). Though it comes at a cost, this will serve to benefit customers and to reduce overall adverse impact of event. Safety measures such as enhanced flight briefings, appropriate pilot training, and continuous streaming of updated current information should be emphasized as weather is unpredictable and subject to change. Overall, comprehensive reviews of incidents and failures and generation of continuous applicable learning for particular locations and scenarios is beneficial. Regarding policy, the expansion of airport capacity at Heathrow and major airports, as well as creation of new airports is essential for better resilience (Deloitte, 2013; Seabury, 2012; DoT, 2013). With no spare capacity, Heathrow is vulnerable to short term operational disruption (BA, 2014; AOA, 2013). Capacity expansion may also enable diversion in times of need easing intense pressure and thus enabling better management of adverse events. Alongside such developments, it is also important to focus on surface connections such as rail and roads to ease pressures of domestic air travel and hence to free some airport capacity (DoT, 2013; Seabury, 2012). They could also serve in times of disruption facilitating diversions and airport transfers. These measures may not be popular however with political players and cust omers seeking convenience.

3. the Future of Religion and Politics in the Developing World

3. The Future of Religion and Politics in the Developing World Religion and Politics are an influential aspect of daily life and continue to affect people today in what they believe in religion and politics. Currently in the news, there is a war regarding religion and beliefs that were made into a movie and portrayed as untrue beliefs from that culture. The politics behind what is brought forth in a story written and then put on a screen has created a religious and political war. Although what was written and produced was viewed as freedom of speech, it has ultimately outraged the believers regarding their religious beliefs.Religion is a belief in someone or something that allows a person to have prayer and beliefs in their culture for the better of their life as they see it. Religion is very much alive as part of politics (Handleman, 2011, p 58). Politics are what affects not only individuals but also countries that should abide by the laws of what are established in order to obtain peace, structure, and control with the people. When religion and politics are put together, they are essentially within the same, beliefs, structure, searching for peace, and allowing a greater being or source to be in control. ReligionsThere are many different types of religions and cultures all over the world. There are many different types of Gods that people have faith in and perform prayer to daily. For centuries, certain religions have stayed within the same beliefs; there are new religions throughout the world that have also not thrived, as well. The church, the laws of the church, and Christianity will continue to be alive and growth on earth every day. People should be allowed to believe in whatever God they choose, but in different countries and with their cultures, people can be brought up to believe only in what they are taught.Catholic Religious Beliefs. There are many religions of the world, and one of the leading religions is Catholicism. The only significant religio n, Catholicism, have penetrated extensively into both industrialized democracies and the developing world, is preeminent in Philippines and Latin America and also is the faith of significant portions of the population in a number of sub-Saharan African countries (Handelman, 2011, p. 60). In Africa, there are more Catholic believers and over half of the populations of all adults are baptized.Inexorably, pastoral and intellectual energy in the church will follow population, and this means that African leaders are destined to play an increasingly prominent role in the global church (Allen, 2006). The world is developing in many areas and having the Catholic belief is becoming stronger than ever. Islamic Religious Beliefs. The Islamic culture is considered not a sacred religion, but one that is of harm and malice. If one would study the Islamic religion, it is not a new religion but one from a path of monotheism.The monotheism too was developed into Judaism and Christianity. The ignoran ce about Islam and perceived targeting of Muslims in general by the U. S. -led â€Å"war on terrorism† have exacerbated a dangerous and growing divide between Muslims and non-Muslims in the contemporary world (Fisher, 2011, p. 381). The Islamic religious beliefs are straightforward to have acceptance, commitment, peace, and purity. They believe in allowing their God for guidance. Politics The balance of politics and what the government has decided for the future is becoming increasingly complex.Politics have become more fundamental in the Third World countries in order to help with the growth and expansion of countries. In order for politics to produce appreciable works, democracy would need to function correctly by the people. Religious beliefs may change over time, but politics are most likely to stay the same. The relationship between politics and religion are to be tolerant and accept changes that occur over time. Politics and Independence. The many cultures in Third Worl d countries seek independence and continue to seek justice from their government and leaders.A threat to the economic well-being is the vast income inequality within developed nations, within many developing nations, and between the developed and developing worlds (Rubin, 2000, p. 421). Each country seeks independence in trade for economic and social changes in order to obtain financial growth. Third World Politics. The principles in other nations seem quite different than what is in the United States. In Third World countries, young children are able to work at an early age in support to be providers in the family.In the United States, there are laws where children cannot work up until a certain age and need to be in a school system. Equal justice to help children with education and development in order to enhance social mobility throughout Third World countries would be beneficial to all. There are many challenges in Third World countries to obtain proper health benefits, and with out assistance, it will often leads to deaths. In conclusion, the world of religion and politics are both needed and desired by many for order and to have something or someone that is of a higher being to respect.Religion and politics will forever be linked throughout the world. Many cultures will continue to either stay within their beliefs of religion or allow changes outside ones control. Politics will continue to be the focus on what the worldviews as structure for each country to abide by their laws set forth by the governments. Although both religion and politics can evolve in war and corruption, there will always be a higher being to seek answers and follow until the end of time.War has evolved from words that are harsh and untrue, but prayer has allowed answers to many questions in which have resolved with effective change.

Thirdly, traditions and taboos are not highly valued as in other areas. Fourthly, the society is what may be described as also low power, based on Hostfedes (1984) classification, where emphasis is laid on consultative relations and this may be misinterpreted by low power societies, which have preference for autocratic approaches (Sutcliffe, 2001). Chinese death ritual traces the traditions of the historical dynasties. These rituals are still observed until today. Rituals are considered as a way of giving respect to the deceased and the elderly. People who die without having married are not often accorded the respect. It is also because they lack the children to organize a decent ceremony for them. Such people are often abandoned at the funeral homes and are never taken home for Chinese death rituals. The same case is applicable for children, who are accorded a silent burial. The corpse is often washed before it is placed in a casket. The dead is dressed black, blue or brown as a way of exalting

Comparison of Southeast Asian and Northeast Asian Art Essay

Comparison of Southeast Asian and Northeast Asian Art - Essay Example The greatest difference in style and perception has been induced by religion, history and the philosophies. The Southeast Asian artworks are a genuine product of Hinduism and Buddhist doctrines drawing from Indian traditions, whereas China, Japan and Korea draw largely from Buddhist and Chinese influences. Again both bear testimony to art production and patronage entertained with social and cultural demands. Cultural interconnections between these two regions are vivid and yet their art signifies an extended cultural code that encloses all the underlying spiritual beliefs of the regions religion-philosophic mind that embed the interrelation of mythology, symbol and spiritual thoughts. The advent of Buddhism introduced sculpture, painting, and architecture of a more religious nature. In China, the figures of Buddha and bodhisattvas became the primary source of influence, although the major route was India, which bore the seat of influence till the 6 th century A.D. The distinction was markedly perfected during the T'ang Dynasty that became more dramatic and restrained by the 7th century that gave way to Major sites of Buddhist art in cave temples include Donghuang, Lung-men, Yun-kang, Mai-chi-shan, and Ping-ling-ssu. Buddhist sculpture in the Ming dynasty became miniature in style made of jade, ivory, and glass, of exquisite craftsmanship but was devoid of any further experimentation and inspiration. The art of figure painting in the T'ang dynasty (618-906) and landscape painting in the Sung dynasty became very prominent. With the coming of the Yuan dynasty (1260-1368) both landscape painting and human painting concentrated more on brushstroke. Brushwork was also done on bamboo and surface painting with a variety of brushwork became an important aspect of still-life painting. Painting during this period became more sophisticated and a part of the leisure culture. Under the Ch'ing dynasty (1644-1912) the applied arts became very technical till the 19th cent., after which with the coming of the communists in the twentieth century art became a product of graphical propaganda. Shih-T'ao and Chu Ta were artists of great creativity. But little or no experimentation in painting marks this period. What is remarkable with Chinese painting is that it has maintained a single characteristic all through history-the extravagant detailing and obsession with the brushstroke. Paintings bore dry or wet-brush technique, with an incredible variety ranging from swirling patterns to staccato dots.1 And thus one inevitably arrives at the highest artwork that the Chinese generated through calligraphy and paintings on ceramics that reached a high perfection in the S 'ung Dynasty. Though calligraphy was part of painting, literature and inscriptions, calligraphy is indebted to Wang Hsi-chih (c.303-361) and his son, who made brushwork the biggest legacy in Chinese art. Chinese architecture also had major impact on Japan, Korea, Vietnam and Taiwan. Unlike Western structure it stresses the visual impact of the width of the buildings rather than its height and depth though Pagodas are a rare exception to this rule. But asymmetry has been part of Chinese art which let the scrolls and also its gardens become a wandering maze of surprises and unique symbolisms. Incase of symbolism, the Chinese also have the greatest and enduring symbols of the

Proposition paper on an ethical in Communication, possibly misogyny in Essay

Proposition paper on an ethical in Communication, possibly misogyny in rap lyrics but topic is flexible - Essay Example This can discourage individuals to communicate unethically. A result will be a more consistent communication in the organization that will give fewer problems. Media of social communication is generally said to develop good or evil communication in people. We might blame media for unethical communication in the society but one should understand that media is not a blind force of nature which is out of human control. But people have to choose if they want to adopt bright side of it or darker. Professional communicators should promote development and enforcement of ethical codes of communication for their profession, public representatives should provide them full support in doing that. Religious bodies and other cultural groups should also be a part of this effort. Communication ethics are known to be cultural specific. What is considered ethical communication in one culture may be considered unethical in another (Chiu, 2003). Because of globalization, individuals from different parts of the world may come together to work in an organization. Values, communication and culture help determine individual behavior. Thus, there are very different interpretations of what sort of communication is ethical or unethical in a given situation. Each individual have their own communication skills and the perception of what is right and ‘wrong’ way of communication may be different Our approach towards means of communication has to be fundamentally positive and encouraging. We should not just simply stand in judgment and start condemning; rather, we should support those professionals who are involved in communication and set out positive principles in their work. Schools and colleges can provide ethical communication education and that will help students to understand how to identify and deal with communication issues (Kreitner and Kinichi, 2001). Teachers can be sent to seminars, workshops and video training sessions to learn about ethical communication issues so

Rights of the individual were primary to the well being of the community Essay Example for Free

Rights of the individual were primary to the well being of the community Essay Nietzsche prefers individuals over community. He believes that all effort should be made for the development and growth of individuals and not for the hoard of men called human society. He does not belong to that group of moralists who held the protection of rights and progress of the whole society primary and that of individuals as secondary. Nietzsche held this group of thinkers in contempt as he is an outspoken supporter of the protection of the rights and multi-dimensional growth of individuals. To community he gives a secondary place because he believes that when the individuals of a community strengthened the whole community will be strengthened. Those communities, he believes, cannot survive for long that care for the whole and not for the individuals. Let us discuss in detail Nietzsche’s vehement support for the primary importance and rights of individuals. Nietzsche believed that all the powers and toil of humanity should be directed towards the overall development of individual human beings and this work should not be wasted by employing it towards raising the status of the whole human society, for instance he said that it is not mankind but superman is his goal. He even refuses to believe in the concrete existence of a collective human society. He criticizes those who believe in work directed towards the development of society. Nietzsche believes that society should work only for the individuals, and individuals should not waste their energies for the betterment of societies. According to him those societies waste their existence at all that failed to produce powerful and worthy individuals. Societies should work as machines for polishing the powers and capabilities of individuals. Nietzsche doesn’t want religion of the society to shackle the free spirit of individuals. He wants a free world for the individuals so that there spirits and intellects should grow to the fullest extent completely unrestrained by any narrow-minded views of the society. That’s the reason he does not look favorably at Christianity and its propagators- the priests. He castigates priesthood and illustrates their depravity in this way; â€Å"Behold these huts which these priests built! Churches they call their sweet-smelling caves. Oh, that falsified light! That musty air! Here the soul is not allowed to soar to its height. For thus their faith commands: â€Å"Crawl up the stairs on your knees, ye sinners! †Ã¢â‚¬ (Nietzsche, 1978. p. 91). He does not want a religion that eats up the rights of individuals. He wants that kind of social setup and social code of life which offers no resistance to the free life of individuals. Even with regards to morality he does not supports that kind of morality which benefits a community and harms the individual. He wants the ‘will’ of individuals to be strengthened and so does not hate the pleasures of flesh. He does not want man to be afraid of the moral laws of society rather he wants him to be brave, strong and independent. Nietzsche wants his men to live a life that is beyond good and evil. An unfettered life. He wants his brave independent men to speak and stammer these words; This is my good; this I love; it pleases me wholly; thus alone do I want the good. I do not want it as divine law; I do not want it as human statute and need: it shall not be signpost for me to over earths and paradises. It is an earthly virtue that I love: there is little prudence in it, and least of all the reason of all men. But this bird built its nest with me: therefore I love and caress it; now it dwells with me, sitting on its golden eggs. (Nietzsche, 1978. p. 36). The life of man, he believes, should not be hindered the strict moral codes made by divinity or community. When the individuals get stronger the society of them will get stronger automatically, this Nietzsche believes. On the other hand if a community kept on giving importance to its well being and not to that of the individuals it will definitely end up in disaster and destruction of both-individual and society. Nietzsche feels that only free men can live and enjoy their lives. The slaves of different passions and laws cannot do that. In his work, Zarathustra spoke to a youth this way; â€Å"You are not yet free, you still search for freedom. You are worn from your search and over awake. You aspire to the free heights, your soul thirsts for the stars. But your wicked instincts, too, thirst for freedom. Your wild dogs want freedom; they bark with joy in their cellar when your spirit plans to open all prisons. To me you are still a prisoner who is plotting his freedom: alas, in such prisoners the soul becomes clever, but also deceitful and bad. And even the liberated spirit must still purify himself. Much prison and mustiness still remain in him: his eyes must still become pure. † (Nietzsche, 1978. p. 43) Free men give birth to free communities and slave men gave birth to slave communities, this Nietzsche seems to believe in his seminal work â€Å"Thus Spoke Zarathustra†. Nietzsche believes that people should be free to get knowledge and dig out truth for themselves. He hates the people who prefer falsehood for the sake of social good. He says again that, â€Å"You have served the people and the superstition of the people, all you famous wise men—and not truth. And that is precisely why you were accorded respect †¦Ã¢â‚¬ ¦thus the master lets his slaves have their way and is even amused by their pranks† (Nietzsche, 1978. p. 102). He believes that the community does not want to accord people the right to believe in and search the truth â€Å"But the free spirit, the enemy of fetters, the non-adorer who dwells in the woods, is as hateful to the people as a wolf to dogs. To hound him out of his lair-that is what the people have ever called ‘a sense of decency’; and against him the people still set their fiercest dogs. † (Nietzsche, 1978. p. 102) He believes that only truth seekers and truthful men could live with dignity, â€Å"Hungry, violent, lonely, godless: thus the lion-will wants itself. Free from the happiness of slaves, redeemed from gods and adorations, fearless and fear inspiring, great and lonely: such is the will of the truthful. † (Nietzsche, 1978. p. 103) For those people who don’t have independent thinking minds he spoke angrily in these words, â€Å"but in the cities dwell the well-fed, famous wise men- the beasts of burden. For, as asses, they always pull the people’s cart. † (Nietzsche, 1978. p. 104) Nietzsche strongly believes that, individuals having independent minds and free-thinking natures raise life to the higher planes of existence; which cannot be done otherwise by slave minds and natures. The community of men will get stronger when the right to search knowledge freely is granted to the individuals and when the individuals themselves struggle to get that right. To sum up, it is stated that Nietzsche is a staunch believer in the rights of individuals. He is one of those thinkers who held the importance of the rights of individual primary and that of community as secondary. According to him a community will get strengthen only when its citizens get strengthen individually. He believes that these individuals should be allowed to grow and develop themselves completely unfettered by the restrictions of the community. Above mentioned arguments and supported evidence clearly manifest Nietzsche’s philosophical orientation about individuality and individual rights. Work Cited Nietzsche, Fredrich. (1978).

Exercise for Balance in the Elderly | Research

Exercise for Balance in the Elderly | Research CHAPTER 1 INTRODUCTION The ageing process is considered as a biological reality, and which cannot be controlled by human being. It is dynamic in nature. The beginning of the old age is about 60 or 65 years and it is equivalent to retirement age. According to the developed countries, old age means at the point when the active contribution is no longer possible (Gorman et al., 2007). As a natural part of aging, physiological and psychological changes can occur and it can affect the lifestyle and health of old age people. Most of the older adults commonly affected by the problems like osteoarthritis, osteoporosis, fractures, diabetes, hypertension, poor vision, hearing impairment, cardiovascular diseases, COPD, poor kidney function, cancers, urinary incontinence, anxiety, depression and balance problems.(Nabili,2010) One of the leading health concerns, in case of elderly is falling and which is related to balance Problems. (Cochrane library).  Balance problems and falls are common, and falls can occur due to impaired balance among elderly .Worldwide, the number of persons over 60 years is growing faster than any other age group. In the middle of the 20th century 14 million people were in the age group of 80 years or older. By, 2050 it will be about 400 million in world wide. Approximately 28-35% of people over the age of 65 fall each year, and this proportion increases to 32-42% for those aged more than 70 years. 40% elderly people living in long term care setting experienced recurrent falls during each year and it is high as compaired to community older adults. Falls may lead to, increased dependence, loss of autonomy, confusion, immobilization and depression. (WHO). According to the centre for control of diseases and prevention (CDC) , one in every 3 adults over the age of 65 falls each year. Walking difficulty and poor balance are common impairments in old age group and which is the high risk for falling. In 2011American geriatric society recommended that all adults aged 65 or older should screen for falls. (Shubert, 2011). Falls can occur in all age groups especially in older adults. The prevalence and incidence of falls more commonly occurs after the age of 65 and (30-60) percentage in annually. As compaired to men, women are more prone to get falls. A study was conducted in Cape Town of South Africa to identify the risk factors of falls. The subjects were selected randomly aged more than 65 years. Total number of samples was 837 from different groups like whites, black Africans and Indians. The study result shows that, incidence of falls was high in women and prevalence of falls was different for different groups. (Kalula, 2010) The risk factors for falls are mainly Gait disturbance, muscle weakness, Dizziness, postural hypotension, visual Impairment, and syncope, use of an assistive device, visual deficit, arthritis, impaired activities of daily living, depression, and cognitive impairment. (WHO, 2006) As age increases, individuals experience decreased strength and balance, which is a risk factor for falls. Balance is the ability to maintain an upright posture during dynamic and static tasks. Maintaining balance requires interactions between central and peripheral factors. (Knerl, 2009) Balance problems are commonly reported by elderly people. Good balance has been associated with independence in daily activities. Deterioration in balance may leads to reduced physical activities and fear of falling. Balance assessments serves several purposes, such as quantitative, description of ability, monitoring subject’s progress overtime and evaluating the effectiveness of intervention.(Sihvonen,2004) For old age people 65 or older, in 2010 the total direct medical cost was 30 billion dollars due to fall injuries and by 2020 it is expected to be about 54.9 billion. Implementation of effective intervention could reduce the health care costs of fall related injuries.(CDC) From the Health Day News, exercise programme means to prevent falls in the seniors, but according to new review it says that exercise programme helps to prevent injuries also. Balance training has been identified as one of the top 10 worldwide in the fitness industry. In 2008 Physical activity guidelines for Americans recommend that balance exercises for 3 days in a week was effective for active and inactive elderly aged more than 65. Gait and balance disorders are common in elderly. As a health care team, physicians or nurses have the responsibility to ask about the previous history of falls. Due to the lack of standardized measures,evidence for the effectiveness of balance training is limited. Yet the exercise and physical therapy are included in effective options for gait and balance. NEED FOR THE STUDY With the exponential growth in older population, exercise is a key target(WHO,2002) and it is a subset of Physical activity that is planned , structural and repetitive and it is considered to be the important rehabilitation programme to improve the functional ability of old age people (Cochrane library). Dr.Nick cavil says that â€Å"A people get older and their bodies decline in function, physical activity helps to slow that decline. In older adults reduced balance is associated with, decreased physical functioning and increase risk of falling. This review analyses the effect of exercise on balance in older adults. (Cochrane editorial unit). In 1960’s an astronaut called John Glenn disqualified from his service, because he experienced balance problems during his working. Then after the rehabilitation programme, at the age of 77, he performed well. As per Indiana University, exercises that speedup swaying that may help to forestall balance problems in later. For the exercise programme safe environment is recommended, for that first step, to acquire sufficient fitness and Self-confidence. Gait balance training is effective, in clinical balance outcomes in elderly. These interventions are probably safe. (Howe, 2011). One in every 3 adults over the age of 65 falls each year . Balance is critical when it comes to avoiding falls at any age. Balance exercise improves strength and flexibility on both sides of the body, not only do they reduce the risk of sips , trips, and falls but also increases the likelihood that seniors will be able to recover balance or reduce the injuries . After 50 years of age , begins to lose 10% of our strength per decade of life , which leads to balance problems. Balance exercise help to reduce the decade of life. (CDC). A study to evaluate the effectiveness of an enhanced balance training programme to improve the mobility of older adults with balance problems. The study was conducted in Bromley Hospitals NHS Trust general hospital; the design adopted for the study was prospective singled blind randomized controlled trial. The subjects participated in the study were 199.The interventional group received balance training programme and control group received physiotherapy. The outcome measures were Berg balance scale,Frenchay Activities Index (FAI), Falls Handicap Inventory (FHI), and European Quality of Life questionnaire were measured regularly at 6,12 and 24 weeks.Both groups showed improvements. (Intervention: 22.5-16.5 seconds, P =.001; control: 20.5-15.8 seconds, P =.054). As by conclusion, the results shows that exercise programmes had an effect on balance among elderly. (Steadman, et.al 2003) Older adults can improve their quality of life by participating in balance exercises. Their by they can improve their mobility and get fit. The researcher says that as age increases, there is a chance of losing muscle mass and strength. Exercise programme helps to improve the postural alignment in sitting and standing position. Many of the older adults, admitted to the hospitals due to decreased balance problem and it results in falls related injuries, so the investigator reveals that exercise programme helps to reduce the falls by improving balance among elderly. According to American journal of epidemiology 30% of community – dwelling seniors /citizens will experiences falls at least once a year due to balance problems. so, as a health care professionals we are responsible to make out the solution. During cinical posting in medical and surgical ward in KMCH, the investigator came across so many persons with fall related injuries due to balance problems, and most of them were in the age group of more than 60.So in order to reduce the rate of falls and to improve the balance the researcher selected the exercise programme as an intervention for elderly people. STATEMENT OF THE PROBLEM Effectiveness of exercise program on balance among elderly in selected old age home at Coimbatore. OBJECTIVES Objectives of the study were to assess the balance score among elderly. determine the effectiveness of exercise programme in improving balance scores. identify the association between the balance scores with selected demographic and clinical variables of elderly people. OPERATIONAL DEFINITIONS Balance:-Ability of an individual to maintain the line of gravity of a body within the base of support with minimal postural sway during different activities such as bending forward, transfer and closing eyes. Exercise programme:- Systematically planned programme for the old age people to improve the balance, of 5 exercises namely sit to stand, heel to toe walk, one leg stand, sideways walking and step up. Elderly:-Both male and female in the age group of 60-80 years. HYPOTHESIS There is a significant improvement in balance following exercise programme among elderly. ASSUMPTIONS Balance impairments are important risk factor for fall. Balance impairments are higher in elderly people. CONCEPTUAL FRAMEWORK A conceptual frame work in nursing is the backbone, on which the nursing research is built. A theoretical explanation of the phenomenon or problem and serves as the basis for the formulation of research hypothesis. The conceptual framework adopted for this study is wiedenbach’s Theory, (1970) which is established by Ernestinewiedenbach, who was early nursing leader. Wiedenbach focuses on individualizing care for each patient. This is done by assessing the individual needs of each patient, so the nurse knows when to step in and help the patient. Central purpose Central purpose of this study is to improve the balance among elderly people. Prescription The investigator plan the prescription that will fulfil the central purpose (improve the balance among elderly).Thus the investigator, selected the method, exercise programme for elderly people, and which is considered to be the effective measure of improving the balance. Realities Agent investigator Recipient elderly people with decreased balance Goal improvement in balance Means provision of exercise (make them to do) Frame work old age home. Identification This includes identification of balance problems among old age people and also importance of exercises and its effects to improve the balance among elderly. Ministration Provision of exerciseprogramme (balance exercise) for elderly with balance problem. Validation Evaluation of the effectiveness of exercise programme on balance with the use of berg balance scale

The Us Is Murdering The Iraqis Essay -- essays research papers

The US is Murdering The Iraqis Each day we eat three meals a day, sometimes more. We listen to music, drive in our cars, or play on our high-tech computers. Some may pick up the newspaper, but other than those few words on the page, the American population is living a life of excess. Excess that is at the expense of other people's lives. The American people take pride in the capitalistic democracy that is a model for the other countries, but they forget to watch the government. They don't even know what their government is doing. For years now people on the street curse and wish death upon the Saddam Hussein. He has been given titles such as the devil's son because the media has told all of the horrible things he has done. The media has shown how he is killing his own people for power. The struggle for power is killing the people of Iraq, but it is not their own government who is fighting for this power, it is the only remaining world super power, the United States of America, fighting constantly to hold on to its domination. It is a ritual of the United States to stop any country from taking our power. The government will destroy any way of life that may take away from the policy of democratic promotion, for the US is the model of such a way of life. If that role was threatened then their power would be threatened. This is shown in the history Iraq and U.S. relations from 1972 on. In 1972, Iraq began to nationalize its oil; large amounts of money where now coming into the country. Saddam was using this money to help his people in a way no other country ever has. A free education system was set up for everyone in the country, from the equivalent of kindergarten to college or professional school. There was free housing for everyone. There was also a medical system that was free for Iraq people, while for non-citizens, it was about three dollars. This three dollars was for everything, from strepp throat to heart surgery. All of this improved the quality of life for the people of Iraq. The infant mortality d ecreased and people were living longer and better lives. Saddam oversaw all of this and his people loved him. But the United States government felt that Saddam and Iraq were growing too powerful in the sensitive Middle East region, and thus began a series of attempts to weaken their power. 1972 is when the U.S. put Iraq on the list of terrorist nations. T... ...ty, behind all the highly confidential, top secret files, they plan to trap these countries under their control while furthering their own power and well being. Children and people of all ages are dying at this moment in Iraq, so that we, the people in America, can live a life of abundant materialism. This is just one country in the world, there are sure to be others in the past, present and the time to come, that will suffer and die at the mercy of the United States of America. Yet people are too concerned with the trivial things of their daily life to take interest in the government that is killing people and destroying cultures. The United States of America is supposed to have the government of the people, so unless we, the people do something, we will continue to be the murderers of innocent people. All of the information in this paper came from Father Harring. He had traveled to Iraq and is working with the Voices in the Wilderness organization to help the people in Iraq. He quit his job as a professor in Connecticutto work full time with the organization. He gave the speech on Iraq sanctions (because Father Gumbleton had been hospitalized and was still ill) in October 1999.

14th Amendment -EQUAL PROTECTION UNDER THE LAW Essay -- essays researc

EQUAL PROTECTION UNDER THE LAW In school especially, as well as throughout our daily lives, we learn in America to live by the idea of freedom and equality for all. We do not allow race, class, or creed to determine a person’s stature in the community. It may seem as if this is the standard of society, but these ideas of equality have been fought over since the beginning of written history, and even in America today, prejudice still exists. To address these and similar problems, the founding fathers of this nation created a Constitution which included laws that dealt with individual freedoms. However great the founding fathers envisioned the United States Constitution, it did not form a perfect union and justice for all. America would have to amend, or add to, the Constitution in order to serve its constituents better. The most powerful constitutional act towards equality would come with the fourteenth amendment. This amendment permanently changed constitutional law by empowering the Federal government†™s jurisdiction to include local and state governments which would be required to abide by new standards of civil rights and privileges. In 1791, the states ratified ten amendments to the United States Constitution. These became known as the Bill of Rights, a cornerstone in providing individual liberty. The United States Senate dropped one of the original proposals stating, â€Å"No state shall violate the equal rights of conscience or the freedom of press or trial by jury in crimi...

Pride In Poetry :: essays research papers

â€Å"And the Devil did grin, for his darling sin is pride that apes humility† (Coleridge). Pride effects everyone and everything. It effects the way that we live, the way that we read and the way that we go about things. It hinders people and events. T.S. Eliot seems to have some experience with this word in context. In his two poems, â€Å"The Love Song of J. Alfred Prufrock† and â€Å"The Journey of the Magi†, there seems to be strong senses of pride and regret of an unfulfilled life. They each make a tour through points in their lives, which seem to have been hard times. Pride puts a bad outlook on life, just like it says in the quote by Coleridge. It is a big problem that drapes over the heads of human kind and seems to be a big thing in the eyes of the speakers in the poems. It is a hard thing to get past and it hurts you very easily. If you live your life in fear, it may end before you can do what you wanted to do with your life. If Eliot’s poems a re doing anything, they are telling people to get past their insecurities and go for it. Eliot could be using himself as an example as someone whom hung up his insecurities and succeeded. Pride is shown a lot in these poems, and it shows why someone should get past it.   Ã‚  Ã‚  Ã‚  Ã‚  In â€Å"The Love Song of J. Alfred Prufrock†, a dead man is going through his life that has been filled with regret. The poem is an ode to Dante’s book, The Divine Comedy, in particular the part entitled Inferno. This is shown in the epilogue of the poem. There is a quote that says, â€Å"If I thought my answer were to one who ever could return to the world, this flame should shake no more, but since none ever did return alive from this depth, if what I hear be true without fear of infamy I answer thee† (Manganiello 18). In Inferno, the speaker overcomes his initial reluctance to reveal his identity when he takes Dante for one of the damned like himself, confined to hell for eternity. The speaker believed that his story would never be told on earth. When he finally announces what it is that happened to him, the words express â€Å"a hidden pride for having once achieved earthly renown and an active desire to vindicate his reputation† ( 19).

Transgender and Stereotypical Feminine Traits

Emily Johanson First Year Seminar Response Paper #4 Final Version due Monday, Nov. 12 Gender Roles in Transamerica Transamerica is an example of how Hollywood portrays transgender people in film. The movie gets rolling when Huffman who portrays Bree a conservative pre-operative transsexual woman tells her therapist she discovered she had a son named Toby. She has to bail him out of jail in order for her therapist to allow her to have her procedure done in a week. The plot unfolds as they get to know each other driving back to California.However, Toby doesn’t know that Bree is his father. Transamerica reinforces a number of transgender stereotypes, and portrays both main characters with stereotypical feminine traits. Throughout the film, Bree reinforces stereotypical transgender behavior. We see this by her taking her hormone pills every day and just trying to blend into the world as a woman. Many people feel that being a transgender is a mental disorder. In the opening of the movie, Bree is in a meeting with her doctor to get her procedure signed off.He is evaluating her to see if she has a mental disorder. Also, Bree’s mom tried to commit her which led to her suicide attempt. When Joyce Murton came to talk to us, she said that many transgender people attempt suicide, so this was a stereotypical behavior. Also, Joyce told us that she didn’t have a good relationship with her family. We also see this in the film. Bree’s mom still sees her as her son Stanley. When they went out to dinner she even had Bree pull out her chair for her which is a stereotypical male behavior.She also made her switch seats so Toby would be next to her. She is using Toby as her replacement son. When Bree told her she never had a son, she broke down in the restaurant. She feels as though she lost a member of her family. I think this is stereotypical for families of transgender people. Bree and Toby display stereotypically feminine traits. Bree may have been bor n male, but she acts exceedingly female; even her tastes in clothing and home decor are very feminine and old-fashioned.On their drive back to California, Bree and Toby stop and camp out for the night. When Bree goes to the bathroom, she is worried about snakes. This is a typical female trait. Also, for being a guy most of her life, she is really good at talking to boys. For example, when she met Calvin she got him to buy her food and drive her to her parent’s house. He ended up developing feelings for her. On the other hand, Toby’s delicate prettiness underscores his vulnerability, as well as his femininity. Toby acts with his sexuality.For example, when he realizes that he has become attached to Bree, he tells her, â€Å"I’ll marry you if you want,† even though she’s given no indication of any romantic or sexual interest. After the car is stolen by the hitchhiker, he deals with it by finding a guy to do what he knows best. The way that Toby used his body to get money or to deal with his problems is a female characteristic. Most males would use their fists not their sexuality. The film Transamerica reinforces stereotypical transgender people, and portrays both Bree and Toby with stereotypical feminine traits.This film really makes you think about how people react to transgender people. Most people would turn away from them and not hire them for a job. However, Toby shows you a different outlook. Instead of being mad at Bree for being a transgender, he was mad at her for lying to him. The other part didn’t bother him. At the end of the film, he even went to Bree’s house and wants to get to know her better. This was inspiring because it allows people to see that a transgender person is just like everyone else, and they shouldn’t feel like they have to hide who they are.

Are People Living in Cities Becoming More Materialistic?

In today's constantly changing society, more and more people are becoming more materialistic. This is particularly so in the cities and more urbanized areas. Take America as an example. Compared with three or four decades ago, Americans today are very much more materialistic. Materialism is usually more apparent in cities because in the cities, people are constantly exposed to new inventions that make life easier. These new inventions often come with a hefty price tag attached to them, simply because they are new products.Human beings being what they are will constantly try to attain the newest and best things in life for themselves. Moreover, city living is such that everyday, you will come into contact with many other people, as city dwellers live within close proximity of one another. As such, on seeing that their neighbours or friends have a certain new product, they too will want to have that, new product as it implies that they have the money to buy the new product. With the ma ssive industrialization programme of the American government over the past two to three decades, America has come a long way.We are now a modern city. Industrialization has improved the living standards of most Americans. as such, our buying power is greater and we are thus able to enjoy more of the luxuries in life. This however has caused many Americans to become materialistic. Nowadays, people tend to judge one another by their outward appearance than their character. If a person is well-dressed and drives an expensive car, he tends to get better service and more respect from the people around him. In the job market. , materialism is also evident..In recent years, employers have complained about young graduates who job-hop. These young graduates have no loyalty whatsoever to the company they work for. As such, when another company offers them the same job but with a higher pay, they simply resign and take up the other offer. Some young graduates have even held four or more differ ent ,jobs within two years. The reason for their job-hopping is simply because each job offers a better pay and nothing else. Materialism is also seen in the shopping habits of people nowadays. People feel that their status comes from what they wear.As such, the budget corners of many department stores are often shunned by the younger more materialistic set. Instead, they flock to designer boutiques like `Ralph Lauren' and `Emporio Armani' to get their outfits. Materialism is not confined to the younger adults. Even teenagers are becoming more materialistic. Materialism in teenagers is due mainly to peer pressure. Many teenagers feel the need for expensive things because their friends have them too. Moreover, as the family size gets smaller and more mothers work. parents often try to make up for the time not spent with their children by giving them more money.Materialism in teenagers can be clearly seen just by looking at the school shoes of most students. The traditional `Bata' sho es have been abandoned for the more prestigious `Reebok', `Nike' or ‘L. A. Gear'. These teenagers experience the power of money at a very young age and therefore grow up having a very materialistic outlook of life. Materialism in America or in any other urbanized city cannot be blamed on anyone but society. It often arises out of peer pressure and also because of a better standard of living. Materialism, therefore, can be considered as a price people have to pay for industrialization.

Lab report

Repeatability measurements were taken on a bolt to get the total length, and also measuring the low rate of a faucet by measuring the amount of time it took to fill a beaker. To ensure a more accurate sample, twenty measurements of each section were obtained. For the batch measurement portion of this lab, a multi-meter was used to measure the resistance in a pack of ten resistors. Each member measured the resistors twice to allow for more precise statistical analysis.After all measurements were recorded, statistical analysis such as mean, standard deviation, and true mean range with 90%, 95%, and 99% confidence intervals were used to obtain the results. Once calculations were made, it was determined that there was error in this vibratory due to the environment and to human error, however all of the results fell within the ranges of confidence for each given section. Relevance In this experiment length, flow rate, and resistance was measured and the true mean was calculated. It was ob served that the true mean varied depending on the variation of the sample mean and sample standard deviation.It was shown that the population mean, or true mean, could not be found exactly, but could be estimated as a range with a certain level of confidence with the measurement of the sample mean and sample standard deviation. The knowledge practiced in this lab can be lawful in future experiments if say a company needs to estimate the population average with a specified level of confidence of a bolt that they only have a few samples of. Introduction There are multiple ways of measurement, as well as, many different types of ways to analyze raw data.In this lab the objective is to experiment with two different types of measurements, repeatability and batch measurements. Theoretically the bolt length plus the cap thickness (B+C) should be equal to the measured total length of the bolt(A). Taking multiple measurements done by multiple people until twenty samples re obtained measuring all four components of the bolt and obtaining the raw data of bolt measurements. By having multiple people take measurements a small amount of human error is removed in case one person didn't measure as accurate.By having multiple measurements done by each person a bigger sample size is obtained, and bigger sample size typically means more accurate results. After the measurements were made a sample mean was calculated, as well as, a sample standard deviation for all four components of the bolt. The sample mean and sample standard deviation were 2 lactated to estimate the true mean of the population with a level of confidence of 90 and 95 percent. Once the true mean of each component was estimated a comparison was made between the total length(A) and the sum of the cap thickness(S) and bolt length(C).In theory (B+C) should equal the total length of the bolt(A), as they represent the same length. Though they should be the same, they are not. The sum of measurements, (B) and (C) yield a much wider range of true mean than the measurement of (A). This difference is created by multiple types of error such as, human error, maybe reading the caliper wrong. Or error such as mechanical error, maybe the caliper itself was broken or not calibrated. In the second module of this lab the flow rate of the faucet water is measured using a stop watch and a mall beaker.Obtaining the flow rate of the water in 20 different samples, then summarizing the raw data into sample mean and sample standard deviation. With the sample mean and standard deviation, the true mean is to be estimated with a confidence level of 90 percent and then again with 95 percent. In the third module the measurements were made in batches. The measurements of batches of resistors were measured with a Center Multi-meter to make sure they all locked in at the same resistance. The resistors measured in this lab were quite strong, getting up to kick.Each group member measured the batch of resistors twice, then a pooled mean and pooled standard deviation was calculated. Pooling all the members samples together gives us one large sample and a more accurate estimate of the true mean. Using these calculated pooled mean and standard deviation the true mean was found as a range with a 99 percent level of confidence, and then again with a 95 percent level of confidence. The experimental setup and procedures are described in section The results of the experiments can be found n section {V} followed by conclusions in section {VI}.The appendix with the data chart can be found in section{Veil} Testing the repeatability of the measurements and taking the sample average and sample standard deviation to compare with each other, as well as, estimate the population mean and standard deviation. In three different modules linear dimension, flow rate, and resistance were measured. The primary objectives of this lab are to practice using devices that measure length and flow rate, to apply statistical principl es to raw data sets, and to become familiar with use off multi-meter. Formulas Used: Sample MeanStandard Deviation True Mean Range 3 Experiment: Equipment: Pittsburgh 6†³ Caliper Bolt Cent-Tech Digital Multi-meter CTD 10 pack of electrical resistors (gold, yellow, red, yellow) mall Beaker Digital Stopwatch Procedure: This experiment utilizes the billeted above. The experiment is broken down into three sections. First take the caliper and the bolt, calibrate the caliper to make sure that accurate measurements are collected. Measure the complete length of the bolt, thickness of the head, width of the threads and the length of the bolt to the base of the head.Repeat the measurement a total of twenty times split evenly between the roof members and record the results. Second, take a mall beaker and a stopwatch to the sink and turn the water faucet on to attain a constant flow rate of water. Use the stopwatch to measure the time it takes from the first drop of water entering the beak er to the instant the water begins to overflow from the top of the beaker. Empty the beaker of water repeat this measurement a total of twenty times split evenly between the group members and record the results. For the last portion of this lab, take a pack of resistors and the multi-meter.Set the millimeter to the appropriate reference resistance and begin measuring each of the sisters one at a 4 time. Each member will measure the set of resistors twice for a total of twenty resistance measurements per each member of the group. Record the measurements from each member and calculate the true mean resistance. Procedure Changes: The only change/ improvement made to the experiment was during the batch measurement section. It was found that more accurate readings of each resistor could be attained by taping the resistor pack to the table to keep it in place while using the probes to measure the resistance.This change will allow the group to move quicker through the experiment and not to make any mistakes such as possibly measuring the same resistor twice in a row. The experimental procedure is very straight forward and the group should not encounter any difficulties. Results/Discussion This lab required three different modules to be completed with two different types of measurements: batch and repeatability. The bolt measurement along with the volume flow rate were to be completed using repeatability, while the resistance module used batch measurements.The data was to be recorded and put into tables and analyzed using the mean, standard deviation, and true mean to determine whether the measurements were in the desired confidence intervals. 5 Linear Dimension Module: The first set of data was recorded using a manual caliper and a bolt. Four measurements were to be taken from the bolt: length, cap thickness, bolt length, and major diameter. These measurements lead to some error as expected, mostly human error and calibration of the manual calipers. There was also so me error due to the uneven sides of the bolt and the angle at which the calipers were held against the bolt.Table la. Shows the summarized data falls within the 95% Confidence Interval. Measurement Total Length (A) Cap Thickness (B) Bolt Length (C) Major Diameter (D) B+C Sample Mean (in. ) (in. ) 2. 2661 0. 0033 0. 2825 0. 0031 1 . 9791 0. 0262 . 30327 0. 0007 2. 2616 0. 0268 Table la.

This is most likely because of the accuracy of two measurements has more mom for error from the angle of the calipers and human error. Table b. Shows the comparison of the two measurements. The full experimental data fo r the linear module is listed in Table A in the Appendix. Table b. Comparison of bolt statistics Flow Rate Module: Measurement of the flow rate from a sink using a stopwatch and beaker was the second of the repeatability measurements.This module produced the most error most likely from human error with stopping and starting of the stopwatch. The inconsistent flow from the sink also contributed to some of the error. The standard aviation in this experiment was high, but after 6 calculating the true mean range for a 90% and 95% confidence interval, the sample mean falls within both ranges with a few outliers. Table LLC. Shows the summary of the data. The full experimental data is listed in Table B in the Appendix . (ECMA/min) 5300. 95 CLC (ECMA/metro) 138. 835 [5247. 27, 5354. 3] Table LLC. Flow Rate Module Statistics 95% CLC (ECMA/metro) [5235. 97, 5365. 93] Resistance Module: In the final part of this lab, resistors were to be measured in batches from each of the group members. This section of the lab showed the most precision with the least error. From the color coded bands on the ten resistors, it was concluded that the value of the resistors was 470 sq. All of the results in table old. Show that the resistors were only reading 400 sq. All 60 recorded measurements were close to 400 ink which could be from mislabel resistors.The pooled mean of the three samples does fall within the 90% and 95% confidence intervals even with including some outliers in the data. The full experimental data can be found in Table C in the Appendix. Sample Mean (Q) 400. 033 99% (Q) 1. 588 [399. 02, 401. 05] Table old. Resistance Module Statistics 95% CLC (sq) [399. 29, 400. 78] Conclusion: This laboratory focused on repeatability measurements, batch measurements, and statistical concepts/ principles to analyze the collected data. This was achieved through the use of a caliper, stopwatch, and a digital multi-meter for measurement purposes.Using these tools, the group is able to meas ure length, flow rate, and resistance. The statistical concepts used in this lab were sample mean, standard deviation, true mean, and the range and level of confidence. The results of the linear dimension module prove that there is always going to be a small amount of human error when using devices such as a manual caliper. That error is relatively larger when trying to sum two measurements as compared to measuring a total length . The measurement of the bolt as a whole has a narrower CIA and true mean range of [2. 265, 2. 267].The 7 standard deviation for total length (A) [0. 0033 in. ] supports the theory that measuring the entire length at once is more accurate than summing the cap thickness (B) and bolt length (C) together, which is evident by analyzing the standard deviation of (B+C) [0. 0268 in. ]. The results of the flow rate module show that there is significantly far more human error when trying to measure the time it takes for water o fill a beaker. This can be attributed to response time of starting/stopping the stopwatch. The standard deviation [138. 835 /min] seems high, but calculations show that the sample mean [5300. 5 /min] falls within the true mean range for CLC [5247. 27, 5354. 63 /metro] and also for 95% CLC [5235. 97, 5365. 93 /min]. The results of the resistance module indicated a difference between the sample mean [400. 033 sq] of the batch measurements and the supposed value of the resistors [470 sq] according to the color coded bands. This was the most precise module with a standard deviation of [1. 588 sq] and all the pooled means fall within he 95% CLC with a true mean range of [399. 29, 400. 78 sq], and the 99% CLC with a range of [399. 02, 401. 05 sq].This laboratory experiment allowed the group to differentiate between repeatability measurements and batch measurements and apply the statistical theories learned in lecture to analyze the collected data. To minimize error percentage, calibrating the caliper before each measurement m ight be advantageous. Another advantage might be making markings on the bolt where each member of the group takes measurements instead of at random/different spots each time. Lab Report Lab Report 3 In this lab, we will take a trip to the planetarium lab and will learn about Right ascension and declination, and altitude and zenith. After looking at the different points shown, we will log the altitude and zenith in the chart in our lab manual. Now we will look at the same points and label the right ascension and declination. Then we will learn about the easiest way to locate the star Polaris. As we started the first program, we answered a few questions to make sure we knew the general idea of stars.Then we labeled the altitude and azimuth of five objects. Aldebran had a altitude of 54o and an azimuth of 203o. Betelgeuse had an altitude of 47o and an azimuth of 203o. Castor had an altitude of 62o and an azimuth 118o. Deneb had an altitude of 13o and an azimuth of 328o. Elnath had an altitude of 68o and an azimuth of 184o. After that, we looked at the right ascension and declination (RA and DEC). Aldebran had a RA of 4. 6 hours and a DEC of 16o. Elnath had an RA of 5. 3 hours and a DEC of 28o. Betelgeuse had an RA of 5. hours and a DEC of 8o. Castor had an RA of 7. 6 hours and a DEC of 32o. Deneb had an RA of 20. 7 hours and a DEC of 46o. Finally we looked at the Big Dipper and the Cassopia to find the star Polaris. This lab was super cool, I loved it. The planetarium was great way to learn more about the different constellations and stars in the sky. I never knew that Polaris was so close to the Big Dipper. Finding the all the right ascensions and declinations of the objects were fairly easy and felt like I learned to do it pretty easily now. Lab Report Example lab report of Synthesis of potassium tris (oxalato) ferrate (III) trihydrate Posted by  Nurul Yunaliyana Experiment 5: Synthesis of potassium tris (oxalato) ferrate (III) trihydrate Purpose: to synthesis potassium tris (oxalato) ferrate (III) trihydrate ,K3 [Fe (C2O4)3]. 3H2O. Introduction: Ferrous ammonium sulfate, Fe(NH4)2(SO4)2. 6H2O is dissolved in a slightly acid solution, excess oxalic acid, H2C2O4, is added and the following reaction takes place: Fe(NH4)2(SO4)2. 6H2O + H2C3O4 FeC2O4(s) + H2SO4 + (NH4)2SO4 + 6H2O FeC2O4 is finely divided precipitate and tends to be colloidal.However, heating the solution causes it to coagulate and facilitates separating the precipitate from the solution. Potassium oxalate is added to the FeC2O4 precipitate, which produces a slightly basic solution for the oxidation of the ferrous ion to the ferric ion, by hydroxide, H2O2. The following reaction takes place: H2O + HO2- +2Fe2+ 2Fe3+ + 3OH- The OH- ion concentration of the solution is hi gh enough so that some of the Fe3+ reacts with OH- to form ferric hydroxide(brown precipitate) as follows: Fe3+ + 3OH- Fe(OH)3 With the addition of more H2C2O4, the Fe(OH)3 dissolves and the soluble complex K3[fe(c2o4)3]. h20 is formed according to : 3k2C2O4 + 2Fe(OH)3 + 3H2C2O4 2K3[Fe(c2o4)3]. 3H20 + 3h2o Ethanol is added to the solution to cause the complex iron salt to precipitate. Data analysis and Discussion: In this experiment, I have studied how to synthesis coordination compound. Coordination compounds are formed when a neutral metal atom: Fe acting as a Lewis acid, reacts with some neutral molecules, acting as Lewis bases; or when a metallic cation, acting as a Lewis acid, reacts with any of a variety of organic or inorganic molecules, cations, or anions, acting as Lewis bases.These Lewis bases: C2O4 and H2O are called ligands. (Lewis acids are electron pair acceptors and Lewis bases are electron pair donors. Ferrous ammonium solution is added with oxalic acid dihydrate sol ution will form yellow solution with yellow precipitate. Fe(NH4)2(SO4)2. 6H2O + H2C3O4 FeC2O4(s) + H2SO4 + (NH4)2SO4 + 6H2O Then it is heated to boiling and the supernatant is decanted. As it is added with solid potassium oxalate, it is allowed to heat at 40 0 C and drop wise added with H2O2 and the solution turns to brown with precipitate for the oxidation of the ferrous ion to the ferric ion.H2O + HO2- +2Fe2+ 2Fe3+ + 3OH- Fe3+ + 3OH- Fe (OH) 3 Next, more oxalic acid dihydrate is added until the solution turns to colourless. 3k2C2O4 + 2Fe (OH) 3 + 3H2C2O4 2K3 [Fe (c2o4)3]. 3H20 + 3h2O The colourless solution is boiled then it turns to pale green solution. The solution is filtered then leaves for crystallization. After that, the green crystal is filtered and washed with 1:1 ethanol/ water and cooled acetone. The mass of bright (luminescent) green crystals is obtained which is 3. 2822 g. So, the percent yield of K3[Fe(C2O4)3]. H2O that I have obtained is 47. 72 %. The precautions tha t we must take are while heat the solution of ferrous ammonium sulfate and solution of oxalic acid dihydrate as it will bump. Next, beware of temperature (at least 40 0 C) of solution when add H2O2 into the solution. The next experiment is determination of the percentage of ligands in coordination compounds. Conclusion : I have studied how to synthesis coordination compound which is potassium tris (oxalato) ferrate (III) trihydrate ,K3 [Fe (C2O4)3]. H2O. The mass of bright (luminescent) green crystals is obtained which is 3. 2822 g. So, the percent yield of K3[Fe(C2O4)3]. 3H2O that I have obtained is 47. 72 %. Reference: 1.

After testing two participants blood pressure and respiration rate, it was found that the vital signs of the participants remained the same after consuming water but decreased slightly after consuming coffee.This lab is significant because it demonstrates that the consumption of coffee, on the contrary to Group 4’s hypothesis, caused a decrease in the vital sign measurements of the two participants rather than increasing as we initially hypothesized. This lab was done to determine and compare the effects that coffee drinking has on blood pressure and the respiration rate in two participants.The hypothesis configured by our group was that after drinking 1 cup of water the par ticipant’s blood pressure and respiration rate would remain constant, but after the drinking 1cup of coffee the participants blood pressure and respiration rate would increase as a result of the common compounds found in coffee. The control in this experiment is 1 cup of water, because the participant’s blood pressure and respiration rate are being measured, but they have not been exposed to the common compounds found in coffee.The dependent variable in the study is the participant’s blood pressure and respiration rate because the vital signs are the component in the experiment that are being measured. The independent variable is what is changed in the experiment and in this experiment that would be the amount of the common compounds the participants consume in 1 cup of coffee. The results of our lab disproved our hypothesis, that consuming coffee would increase the participant’s blood pressure and respiration rate, as seen in Table 1, Graph 1, and Graph 2.Although our expectations of the measurement of vital signs after consuming 1 cup of water were correct, we had expected the results from the measurement of both the respiration rate and the blood pressure to noticeably increase after consuming coffee due to the common compounds found in coffee. The lab, actually, resulted in the decrease of respiration rate and blood pressure after the consumption of coffee.The study preformed by the National Cancer Institute measured the association between coffee and its affects on health, as a result of reading this article I conducted a study that worked off the same principle. However, in the lab I attempted to narrow the causal relationship between the two by measuring the participant’s vital signs, respiration rate and blood pressure, in relationship to consuming coffee versus water and any potential periods or repeated periods of evaluated or descended vital signs has to the longevity of one’s life.The results of the lab sup port the findings of the National Cancer Institute because the article states that consuming coffee has positive affects on health and our lab concluded that coffee consumption lowers blood pressure, which is necessary for a person that may struggle with high blood pressure to become healthy. During the lab, the participants physiology, blood pressure and respiration rate, was lowered after consuming coffee, this served to calm the participant’s vital signs. To improve the validity of the study a few changes could be made to improve the results.For example, I believe that the vital signs were not effected greatly because of the time span used to complete the study, after drinking the coffee we immediately took the vital signs instead of waiting for the full effect to take place. An additional reason for the higher levels of the vital signs before the consumption of coffee could have been due to activities done prior to the lab thus increasing the vital sings measured after dr inking water. To improve upon these imperfections, the study could be done earlier in the day and with more resting periods before vital signs are taken.This lab was designed to determine the relationship between coffee consumption and two types of vital signs, respiration and blood pressure. The lab measured the respiration rate and blood pressure of two participants, once after consuming water and then again after consuming coffee. I hypothesized that the consumption of coffee would dramatically increase the participant’s respiration rate and blood pressure due to the consumption of the common compounds found in coffee that typically raise energy levels and alertness.However, the lab resulted in slightly lower respiration rates and blood pressure after the consumption of coffee than water as seen in Table 1, Graph 1, and Graph 2. The lab is significant because it demonstrates that the consumption of coffee, in contrast to our hypothesis, caused a decrease in the vital sign measurements of the two participants rather than increasing as we originally hypothesized.

Web. 9 Oct. 2012 Lab report Repeatability measurements were taken on a bolt to get the total length, and also measuring the low rate of a faucet by measuring the amount of time it took to fill a beaker. To ensure a more accurate sample, twenty measurements of each section were obtained. For the batch measurement portion of this lab, a multi-meter was used to measure the resistance in a pack of ten resistors. Each member measured the resistors twice to allow for more precise statistical analysis.After all measurements were recorded, statistical analysis such as mean, standard deviation, and true mean range with 90%, 95%, and 99% confidence intervals were used to obtain the results. Once calculations were made, it was determined that there was error in this vibratory due to the environment and to human error, however all of the results fell within the ranges of confidence for each given section. Relevance In this experiment length, flow rate, and resistance was measured and the true mean was calculated. It was ob served that the true mean varied depending on the variation of the sample mean and sample standard deviation.It was shown that the population mean, or true mean, could not be found exactly, but could be estimated as a range with a certain level of confidence with the measurement of the sample mean and sample standard deviation. The knowledge practiced in this lab can be lawful in future experiments if say a company needs to estimate the population average with a specified level of confidence of a bolt that they only have a few samples of. Introduction There are multiple ways of measurement, as well as, many different types of ways to analyze raw data.In this lab the objective is to experiment with two different types of measurements, repeatability and batch measurements. Theoretically the bolt length plus the cap thickness (B+C) should be equal to the measured total length of the bolt(A). Taking multiple measurements done by multiple people until twenty samples re obtained measuring all four components of the bolt and obtaining the raw data of bolt measurements. By having multiple people take measurements a small amount of human error is removed in case one person didn't measure as accurate.By having multiple measurements done by each person a bigger sample size is obtained, and bigger sample size typically means more accurate results. After the measurements were made a sample mean was calculated, as well as, a sample standard deviation for all four components of the bolt. The sample mean and sample standard deviation were 2 lactated to estimate the true mean of the population with a level of confidence of 90 and 95 percent. Once the true mean of each component was estimated a comparison was made between the total length(A) and the sum of the cap thickness(S) and bolt length(C).In theory (B+C) should equal the total length of the bolt(A), as they represent the same length. Though they should be the same, they are not. The sum of measurements, (B) and (C) yield a much wider range of true mean than the measurement of (A). This difference is created by multiple types of error such as, human error, maybe reading the caliper wrong. Or error such as mechanical error, maybe the caliper itself was broken or not calibrated. In the second module of this lab the flow rate of the faucet water is measured using a stop watch and a mall beaker.Obtaining the flow rate of the water in 20 different samples, then summarizing the raw data into sample mean and sample standard deviation. With the sample mean and standard deviation, the true mean is to be estimated with a confidence level of 90 percent and then again with 95 percent. In the third module the measurements were made in batches. The measurements of batches of resistors were measured with a Center Multi-meter to make sure they all locked in at the same resistance. The resistors measured in this lab were quite strong, getting up to kick.Each group member measured the batch of resistors twice, then a pooled mean and pooled standard deviation was calculated. Pooling all the members samples together gives us one large sample and a more accurate estimate of the true mean. Using these calculated pooled mean and standard deviation the true mean was found as a range with a 99 percent level of confidence, and then again with a 95 percent level of confidence. The experimental setup and procedures are described in section The results of the experiments can be found n section {V} followed by conclusions in section {VI}.The appendix with the data chart can be found in section{Veil} Testing the repeatability of the measurements and taking the sample average and sample standard deviation to compare with each other, as well as, estimate the population mean and standard deviation. In three different modules linear dimension, flow rate, and resistance were measured. The primary objectives of this lab are to practice using devices that measure length and flow rate, to apply statistical principl es to raw data sets, and to become familiar with use off multi-meter. Formulas Used: Sample MeanStandard Deviation True Mean Range 3 Experiment: Equipment: Pittsburgh 6†³ Caliper Bolt Cent-Tech Digital Multi-meter CTD 10 pack of electrical resistors (gold, yellow, red, yellow) mall Beaker Digital Stopwatch Procedure: This experiment utilizes the billeted above. The experiment is broken down into three sections. First take the caliper and the bolt, calibrate the caliper to make sure that accurate measurements are collected. Measure the complete length of the bolt, thickness of the head, width of the threads and the length of the bolt to the base of the head.Repeat the measurement a total of twenty times split evenly between the roof members and record the results. Second, take a mall beaker and a stopwatch to the sink and turn the water faucet on to attain a constant flow rate of water. Use the stopwatch to measure the time it takes from the first drop of water entering the beak er to the instant the water begins to overflow from the top of the beaker. Empty the beaker of water repeat this measurement a total of twenty times split evenly between the group members and record the results. For the last portion of this lab, take a pack of resistors and the multi-meter.Set the millimeter to the appropriate reference resistance and begin measuring each of the sisters one at a 4 time. Each member will measure the set of resistors twice for a total of twenty resistance measurements per each member of the group. Record the measurements from each member and calculate the true mean resistance. Procedure Changes: The only change/ improvement made to the experiment was during the batch measurement section. It was found that more accurate readings of each resistor could be attained by taping the resistor pack to the table to keep it in place while using the probes to measure the resistance.This change will allow the group to move quicker through the experiment and not to make any mistakes such as possibly measuring the same resistor twice in a row. The experimental procedure is very straight forward and the group should not encounter any difficulties. Results/Discussion This lab required three different modules to be completed with two different types of measurements: batch and repeatability. The bolt measurement along with the volume flow rate were to be completed using repeatability, while the resistance module used batch measurements.The data was to be recorded and put into tables and analyzed using the mean, standard deviation, and true mean to determine whether the measurements were in the desired confidence intervals. 5 Linear Dimension Module: The first set of data was recorded using a manual caliper and a bolt. Four measurements were to be taken from the bolt: length, cap thickness, bolt length, and major diameter. These measurements lead to some error as expected, mostly human error and calibration of the manual calipers. There was also so me error due to the uneven sides of the bolt and the angle at which the calipers were held against the bolt.Table la. Shows the summarized data falls within the 95% Confidence Interval. Measurement Total Length (A) Cap Thickness (B) Bolt Length (C) Major Diameter (D) B+C Sample Mean (in. ) (in. ) 2. 2661 0. 0033 0. 2825 0. 0031 1 . 9791 0. 0262 . 30327 0. 0007 2. 2616 0. 0268 Table la.

This is most likely because of the accuracy of two measurements has more mom for error from the angle of the calipers and human error. Table b. Shows the comparison of the two measurements. The full experimental data fo r the linear module is listed in Table A in the Appendix. Table b. Comparison of bolt statistics Flow Rate Module: Measurement of the flow rate from a sink using a stopwatch and beaker was the second of the repeatability measurements.This module produced the most error most likely from human error with stopping and starting of the stopwatch. The inconsistent flow from the sink also contributed to some of the error. The standard aviation in this experiment was high, but after 6 calculating the true mean range for a 90% and 95% confidence interval, the sample mean falls within both ranges with a few outliers. Table LLC. Shows the summary of the data. The full experimental data is listed in Table B in the Appendix . (ECMA/min) 5300. 95 CLC (ECMA/metro) 138. 835 [5247. 27, 5354. 3] Table LLC. Flow Rate Module Statistics 95% CLC (ECMA/metro) [5235. 97, 5365. 93] Resistance Module: In the final part of this lab, resistors were to be measured in batches from each of the group members. This section of the lab showed the most precision with the least error. From the color coded bands on the ten resistors, it was concluded that the value of the resistors was 470 sq. All of the results in table old. Show that the resistors were only reading 400 sq. All 60 recorded measurements were close to 400 ink which could be from mislabel resistors.The pooled mean of the three samples does fall within the 90% and 95% confidence intervals even with including some outliers in the data. The full experimental data can be found in Table C in the Appendix. Sample Mean (Q) 400. 033 99% (Q) 1. 588 [399. 02, 401. 05] Table old. Resistance Module Statistics 95% CLC (sq) [399. 29, 400. 78] Conclusion: This laboratory focused on repeatability measurements, batch measurements, and statistical concepts/ principles to analyze the collected data. This was achieved through the use of a caliper, stopwatch, and a digital multi-meter for measurement purposes.Using these tools, the group is able to meas ure length, flow rate, and resistance. The statistical concepts used in this lab were sample mean, standard deviation, true mean, and the range and level of confidence. The results of the linear dimension module prove that there is always going to be a small amount of human error when using devices such as a manual caliper. That error is relatively larger when trying to sum two measurements as compared to measuring a total length . The measurement of the bolt as a whole has a narrower CIA and true mean range of [2. 265, 2. 267].The 7 standard deviation for total length (A) [0. 0033 in. ] supports the theory that measuring the entire length at once is more accurate than summing the cap thickness (B) and bolt length (C) together, which is evident by analyzing the standard deviation of (B+C) [0. 0268 in. ]. The results of the flow rate module show that there is significantly far more human error when trying to measure the time it takes for water o fill a beaker. This can be attributed to response time of starting/stopping the stopwatch. The standard deviation [138. 835 /min] seems high, but calculations show that the sample mean [5300. 5 /min] falls within the true mean range for CLC [5247. 27, 5354. 63 /metro] and also for 95% CLC [5235. 97, 5365. 93 /min]. The results of the resistance module indicated a difference between the sample mean [400. 033 sq] of the batch measurements and the supposed value of the resistors [470 sq] according to the color coded bands. This was the most precise module with a standard deviation of [1. 588 sq] and all the pooled means fall within he 95% CLC with a true mean range of [399. 29, 400. 78 sq], and the 99% CLC with a range of [399. 02, 401. 05 sq].This laboratory experiment allowed the group to differentiate between repeatability measurements and batch measurements and apply the statistical theories learned in lecture to analyze the collected data. To minimize error percentage, calibrating the caliper before each measurement m ight be advantageous. Another advantage might be making markings on the bolt where each member of the group takes measurements instead of at random/different spots each time. Lab Report Lab Report 3 In this lab, we will take a trip to the planetarium lab and will learn about Right ascension and declination, and altitude and zenith. After looking at the different points shown, we will log the altitude and zenith in the chart in our lab manual. Now we will look at the same points and label the right ascension and declination. Then we will learn about the easiest way to locate the star Polaris. As we started the first program, we answered a few questions to make sure we knew the general idea of stars.Then we labeled the altitude and azimuth of five objects. Aldebran had a altitude of 54o and an azimuth of 203o. Betelgeuse had an altitude of 47o and an azimuth of 203o. Castor had an altitude of 62o and an azimuth 118o. Deneb had an altitude of 13o and an azimuth of 328o. Elnath had an altitude of 68o and an azimuth of 184o. After that, we looked at the right ascension and declination (RA and DEC). Aldebran had a RA of 4. 6 hours and a DEC of 16o. Elnath had an RA of 5. 3 hours and a DEC of 28o. Betelgeuse had an RA of 5. hours and a DEC of 8o. Castor had an RA of 7. 6 hours and a DEC of 32o. Deneb had an RA of 20. 7 hours and a DEC of 46o. Finally we looked at the Big Dipper and the Cassopia to find the star Polaris. This lab was super cool, I loved it. The planetarium was great way to learn more about the different constellations and stars in the sky. I never knew that Polaris was so close to the Big Dipper. Finding the all the right ascensions and declinations of the objects were fairly easy and felt like I learned to do it pretty easily now. Lab Report Example lab report of Synthesis of potassium tris (oxalato) ferrate (III) trihydrate Posted by  Nurul Yunaliyana Experiment 5: Synthesis of potassium tris (oxalato) ferrate (III) trihydrate Purpose: to synthesis potassium tris (oxalato) ferrate (III) trihydrate ,K3 [Fe (C2O4)3]. 3H2O. Introduction: Ferrous ammonium sulfate, Fe(NH4)2(SO4)2. 6H2O is dissolved in a slightly acid solution, excess oxalic acid, H2C2O4, is added and the following reaction takes place: Fe(NH4)2(SO4)2. 6H2O + H2C3O4 FeC2O4(s) + H2SO4 + (NH4)2SO4 + 6H2O FeC2O4 is finely divided precipitate and tends to be colloidal.However, heating the solution causes it to coagulate and facilitates separating the precipitate from the solution. Potassium oxalate is added to the FeC2O4 precipitate, which produces a slightly basic solution for the oxidation of the ferrous ion to the ferric ion, by hydroxide, H2O2. The following reaction takes place: H2O + HO2- +2Fe2+ 2Fe3+ + 3OH- The OH- ion concentration of the solution is hi gh enough so that some of the Fe3+ reacts with OH- to form ferric hydroxide(brown precipitate) as follows: Fe3+ + 3OH- Fe(OH)3 With the addition of more H2C2O4, the Fe(OH)3 dissolves and the soluble complex K3[fe(c2o4)3]. h20 is formed according to : 3k2C2O4 + 2Fe(OH)3 + 3H2C2O4 2K3[Fe(c2o4)3]. 3H20 + 3h2o Ethanol is added to the solution to cause the complex iron salt to precipitate. Data analysis and Discussion: In this experiment, I have studied how to synthesis coordination compound. Coordination compounds are formed when a neutral metal atom: Fe acting as a Lewis acid, reacts with some neutral molecules, acting as Lewis bases; or when a metallic cation, acting as a Lewis acid, reacts with any of a variety of organic or inorganic molecules, cations, or anions, acting as Lewis bases.These Lewis bases: C2O4 and H2O are called ligands. (Lewis acids are electron pair acceptors and Lewis bases are electron pair donors. Ferrous ammonium solution is added with oxalic acid dihydrate sol ution will form yellow solution with yellow precipitate. Fe(NH4)2(SO4)2. 6H2O + H2C3O4 FeC2O4(s) + H2SO4 + (NH4)2SO4 + 6H2O Then it is heated to boiling and the supernatant is decanted. As it is added with solid potassium oxalate, it is allowed to heat at 40 0 C and drop wise added with H2O2 and the solution turns to brown with precipitate for the oxidation of the ferrous ion to the ferric ion.H2O + HO2- +2Fe2+ 2Fe3+ + 3OH- Fe3+ + 3OH- Fe (OH) 3 Next, more oxalic acid dihydrate is added until the solution turns to colourless. 3k2C2O4 + 2Fe (OH) 3 + 3H2C2O4 2K3 [Fe (c2o4)3]. 3H20 + 3h2O The colourless solution is boiled then it turns to pale green solution. The solution is filtered then leaves for crystallization. After that, the green crystal is filtered and washed with 1:1 ethanol/ water and cooled acetone. The mass of bright (luminescent) green crystals is obtained which is 3. 2822 g. So, the percent yield of K3[Fe(C2O4)3]. H2O that I have obtained is 47. 72 %. The precautions tha t we must take are while heat the solution of ferrous ammonium sulfate and solution of oxalic acid dihydrate as it will bump. Next, beware of temperature (at least 40 0 C) of solution when add H2O2 into the solution. The next experiment is determination of the percentage of ligands in coordination compounds. Conclusion : I have studied how to synthesis coordination compound which is potassium tris (oxalato) ferrate (III) trihydrate ,K3 [Fe (C2O4)3]. H2O. The mass of bright (luminescent) green crystals is obtained which is 3. 2822 g. So, the percent yield of K3[Fe(C2O4)3]. 3H2O that I have obtained is 47. 72 %. Reference: 1.
