Wheelchair Forces. The Forces And Kinematics Involved In Self Essay

Wheelchair Forces. The Forces And Kinematics Involved In Self Propelling A Wheelchair - Essay Example The study took place at the Stanmore Clinical Research Facility (SCRF) at the Royal National Orthopaedic Hospital (RNOH), Stanmore. All participants gave informed consent to participate in the study. (Refer to Appendix __ ). The generation of forces were gathered through the front castors of the wheelchair and through the push rim. The forces generated are then recorded and analysed to investigate the hypothesis stated. The wheelchair users P:C Ratio was then calculated to establish whether the users exceeded their capacity when performing such tasks and whether Rear Axle Position (RAP) was found to influence this. As there are no existing methods for testing dynamic wheelchair stability of a manual wheelchair, an instrument was developed. Consequently, a force sensitive castor was designed to look at this pattern in more detail. The chosen model was a 17" Quickie GPV, rigid frame lightweight wheelchair. The model was chosen as the most adaptable size for most test participants and was then configured to suit each individual's needs. The wheelchair weighs 18kg with nearly 7kg of added weight due to an attached equipment. The wheelchair is fitted with 25" solid tyres to accommodate the Smart Wheel technology and 5" solid castors. There is a 3-degree camber on the rear wheels. Figure 1. Quickie GPV Wheelchair Each participant was set up in the Laboratory's test wheelchair. Only one wheelchair could be used as the instrumentation was not interchangeable between wheelchairs. 1.3.3 Development of the Castor Force Transducer An earlier work at ACDS (spell out acronym) (WOWSUP, 2005) using a wheelchair Ergometer showed that there was a substantial weight shift between castors and rear wheels during the propulsion cycle, which subsequently increased with the pushing resistance. The Ergomenter used force plates beneath the front castors during propulsion. The study explored what happened to the Ergometer when users propelled their wheelchairs to perform functional activities. A force sensor was integrated into the castor stem of the wheelchair to examine weight shift during functional mobility. This was initially constructed in combination with the castor stem and a number of washers to accommodate its size. Figure 2. The Wheelchair Ergometer 1.3.4 Calibration of the castor force transducer This was completed by loading the wheelchair with known masses and recording the voltage output from both the force transducer in the castor and the force plate underneath it (force plates already calibrated for previous testing). This calibration produced 2 curves in order to demonstrate whether a linear relationship was achievable

Significance of the Dog in J.M. Coetzee's disgrace Essay

Significance of the Dog in J.M. Coetzee's disgrace - Essay Example This is Coetzee’s first book that deals explicitly with South Africa’s post apartheid scenario, that paints a cheerless picture and comforts no one, no matter to which race or nationality they belong. Coetzee’s primary theme in ‘Disgrace’ revolves around a man who is broken down and reduced to almost nothing, but finally searches and finds a small speck of redemption by way of his acceptance of the realities of life and death. The protagonist in the story is Professor David Lurie and Coetzee’s notion of life with its harsh realities and brutal tyranny being replaced by brutal anarchy are reflected through his protagonist David in South Africa, a place filled with social and political conflicts. Coetzee’s scintillating novel makes use of a metaphorical device such as the use of different animals and in particular dogs to bring out the developments of his characters. Dogs play a stylistic role in this novel as it is portrayed as being a m eans of protection for the Whites. During his childhood, Coetzee’s mother created a great impact on him where dogs were concerned. It is her influence which was a major contributing factor for Coetzee to use dogs as the defining factor in his novel ‘Disgrace’. His mother often reflected on her past life which included the â€Å"walks with the dogs†. ... David is a divorced, middle-aged scholar of Romantic poetry, who during the Mandela Era, became a victim of "the great rationalization". His university was replaced by a Technical University at Cape Town where he teaches lessons in â€Å"Communicative skills† that he finds rather useless and nonsensical. The dignity he has there, is short lived as he is caught having a relationship with one of his poetry students and is dismissed from the university. Coetzee describes him as â€Å"a mad old man sitting among the dogs singing to himself†; a man who invests his last savings into a pickup truck to pursue his work as a dog-undertaker. David further sinks in disgrace when he patronizes a prostitute and buys her gifts, but in the course of this relationship he becomes such a nonentity that she refuses to see him. He imagines her and her friends shuddering when they see him just as  "as one shudders at a cockroach in a washbasin in the middle of the night". David contemplate s asking his doctor to castrate him in the way one neuters a domestic animal. In Coetzee’s story this is the first reference made between human and animal existence. One of Coetzee’s striking techniques is to explore what it is to be human, which is deftly brought out through his characters by placing them in extreme and compelling situations. The protagonist David has to experience and endure physical torment and psychological abasement. He falls deep into disgrace and flees Cape Town to his daughter Lucy’s remote farm. Lucy hears his story and very matter- of- factly tells him, "This is the only life there is. Which we share with animals." This is another one of the comparisons made in this story between humans and

Why People Should Pay for Plastic Bags Research Paper

Why People Should Pay for Plastic Bags - Research Paper Example This essay stresses that a number of countries all over the world has already banned the use of plastic bags or provided that people should pay for them in stores. Among these countries are Australia, the United Kingdom, China, Germany, Ireland, Italy, Denmark, India, Israel, Malaysia, Hong Kong and others. In the United States, it is only cities and counties that outlawed the use of plastic bags. In September 2014, California imposed a ban on plastic bags. It is difficult to predict the outcomes of a plastic bag tax in the United States. However, the experience of other countries that implemented this tax or even banned the use of plastic bags is promising. For example, Ireland introduced a plastic bag tax in 2002, and since that year, the amount of plastic bag litter in the country gas reduced by ninety-five percent. In 2008, China introduced a total ban on ultra-thin plastic bags and a tax on plastic bags, and since that year, the use of plastic bags in the country has reduced, wh ich means that the amount of plastic bags litter has also decreased. This paper makes a conclusion that the modern state of the environment as well as the threats imposed by plastic bags on it and on public health suggest that the use of plastic bags should be limited, and one of the ways to decrease the use is to make people pay for plastic bags in stores. Experience of a range of countries in the world and cities and counties in the United States shows that a plastic bag fee really works and helps improve the situation with environmental pollution.

Health Care in America, the Incurable Debate Essay

Health Care in America, the Incurable Debate - Essay Example (Klein, 2012). Republicans question the figures but can pretty much live with the rest or watered-down versions of it. The individual mandate is at the heart of the debate. It is this part that sent the law to the High Court and, depending on which side characterizes it, is an egregious infringement on liberty or a fair and necessary part of the legislation. The individual mandate, which legally obliges all who can afford it to buy health care insurance based on a sliding income scale, was conceived during the 1990’s version of the health care debate. First Lady Hillary Clinton was tasked with the immense issue of health care reform in an attempt to design a bill that would cover more people while curbing costs. During this contentious, highly partisan debate the Republicans demanded that individual responsibility was written into the law and favored the individual mandate. Democrats hesitated at first but relented in an effort to pass something, even a much smaller version th an they initially envisioned. Fast forward 15 years. Tea Party Republicans have made the mandate a centerpiece of their argument against reforming the overly costly system. They claim the ACA is a â€Å"government takeover of health care.† (Goozner, 2010). Republicans also claim the mandate is unconstitutional. They contend states have the authority but not the federal government. That’s why people can be forced to carry auto insurance. It’s a state requirement. Democrats might say they didn’t take that position when they conceived it themselves just a few years ago and point to the Interstate Commerce Clause as legal justification for the mandate. Americans’ opinion of the mandate has changed along party lines, of course,... Health care reform is literally a life and death issue both for people and the economy. The present system, prior to the full implementation of the ACA, is costing citizens their health and contributing to the National Debt. Something must be done. If not the ACA then what? If the country is waiting on Republicans to fix the system they have a long wait. Health care is not their priority as evidenced by the previous administrations complete failure to address the topic at all. It is difficult for Washington to tackle a complex issue such as health care and seldom politically advantageous. The Democrats tried but failed during the 1990’s and have tried again, each time struggling to pass a bill against a concerted and organized campaign to defeat it, a campaign of obvious lies and propaganda, the â€Å"death panels’ to kill your grandmother misinformation for example. Because of this scare tactic health care reform, so essential to people and the nation, may again go do wn in defeat and must wait for another Democratic administration to try yet another time.

The American Red Cross Research Paper Example | Topics and Well Written Essays - 1250 words

The American Red Cross - Research Paper Example Business ethics come with numerous benefits which include employee commitment which can be said to be the believe of an employee future to be linked to that of the organization and their personal sacrifices they willingly offer to that organization they work for.In addition, investor loyalty can be said to be th ethical code of conduct that gives rise to shareholder loyalty which might pay a regular contribution to success supporting even greater anxiety and social causes (Ferrell, Fraedrich & Ferrell, 2011). Moreover,customer satisfaction is one of the greatest important aspect of a business success is the organizational development continuation, alteration and adaptation of products to keep the customer trends of tastes and preferences so that long - term stakeholders and customer relationship is maintained. Lastly,the bottom line is the relation to business to the total revenue minus all the expenses and therefore any company or organization must have a good financial presentation for the purpose of ethical culture nurturing and development (Ferrell, Fraedrich & Ferrell, 2011).Due to the behavior of the American Red Cross (ARC) following the aftermath of Hurricane Katrina and 9/11 their reputation with regard to business effects benefits were greatly dented. This was as a result of lack of supervision of some volunteers or employees, leading them to be an unethical in the operation and also resulted in numerous damage of the ARC reputation. Due to the ARC failure to strictly follow their rules and regulations and embezzled donated funds for the organization, the investor loyalty greatly reduced( Jones, 2012). The deeds of the ARC following these calamities led to low customer satisfaction which greatly affected the profits which are directly proportional to the organizational actions. Since the ARC major source of revenues is the donations, the public may stop the donations at their will if they feel their money is embezzled instead of assist the needy( Jone s, 2012). . Determine and discuss the role that ARC’s stakeholder orientation played in this scenario. Stakeholder orientation is defined as the level of an organization's ability to recognize and tackle stakeholder demands. The stakeholders made up by a number of people who may have a say in any company or organization’s business operations( Jones, 2012). . A lot of distress arose about ARC in the scenario and since its major role is to give a fast response aid to victims of any disaster, the World Trade Center attack in New York city and the Hurrican Katrina were chief occurrences that were of great effect in the United States. The way in which ARC carried out those events was questionable making it to be highly scrutinized. Starting with the World Trade Center, the ARC got higher criticism due to their slow response time. The Disaster operation center (DOC) whose center of command is based in Virginia never activated the special teams which are usually sent in respo nse to a plane crash disaster or similar (Jones, 2012). . Apart from the slow response to disaster that took place in 9/11 2001, criticism also arose due to the fact that some of the money donated was mismanaged. This money was raised from a separate fund which was to cater for the victims and the affected families. In a period of about two months, about $550 millions was collected with only about a third going to the intended function of relief

Leonardo Da Vinci Biography And Artwork Essay Example | Topics and Well Written Essays - 1250 words

Leonardo Da Vinci Biography And Artwork - Essay Example c contributions of Davinci; and the image of the angel has evoked controversy with regard to its pose, complexion, and non conventional form (Scaramella). The Baptism of Christ One of the most famous paintings of Leonardo da Vinci Mona Lisa an oil painting painted on a poplar wood. This was created between 1503 and 1519, and is the most parodied piece of art till date. According to critics, Da Vinci kept a long held mystery that loomed over her eyebrows. The image in the painting is believed to be the portrait of Lisa Gherardini, wife of Francesco del Giocondo. Mona Lisa is painted in a realistic scale. It has a complete volume typically seen in sculpture in the round. The painting is believed to have been created between 1503 and 1506. Da Vinci's Mona Lisa is the earliest Italian portrait to focus so clearly on a passenger in a half-length portrait. Mona Lisa is highly realistic and that is attributed to the technique of sfmuto he used to blend and shade the contours from his light to dark work and to soften the image to make it more lifelike. As Botton points out, Christianity maintained the Aristotle’s concept that ‘miseries of works were an appropriate means of expiating the sins of Adam’; and it was since the advent of Leonardo and Michelangelo that ‘new notes began to be heard’ (106). Mona Lisa Evidently, monalisa as a wonderful work of art has been the topic for reseac over centuries. Although researchers are at odds regarding various aspects of the painting, they all converge at the point that Da Vinci’s art worth great appreciation for ever. Recent studies conducted on the painting have brought out amazing findings about the secrets the painter had employed in the creation of his masterpiece. According to Cotte, the founder of Lumiere Technology... Da Vinci’s relationship with the Roman Catholic Church itself is a topic for debate. Many believe that da Vinci was not a staunch believer of Catholic Church despite the fact that many of his paintings are based on biblical themes. For instance, as Rosci's notes, Leonardo "adopted an empirical approach to every thought, opinion, and action and accepted no truth unless verified or verifiable, whether related to natural phenomena, human behavior, or social activities."And hence, according to this observation, da Vinci did not believe in the Catholic dogma and was an insurgent seeking to over through the false beliefs of the society in which he lived. Evidently, as compared to Michelangelo, da Vinci got only a nominal support from the Catholic Church in his pursuit. In the same way, Leonardo’s relationship with his contemporary Michelangelo also was not very substantial, the reason for which is still not sure. However, he was an exceptional figure in the history that prove d his part in almost all branches of art and science. In total, Leonardo Da Vinci is considered to be an artist, an inventor and an eminent scientist whose ideas were centuries ahead than the time he lived. More than five hundred years Da Vinci’s reputation as a famous painter rested with a number of paintings which is considered to be the ultimate masterpieces in the world. Da Vinci’s exceptional draftsmanship is clear in his larger body of drawings which were later seen in a number of European art works and in art galleries.
