Analysis - Research Paper Example But the use of buffered lidocaine faces some issues as it is a compounded medication and needs to be procured from the pharmacy and with its short half-life the FDA requires this solution to be replaced weekly which has been adopted even for this present study. In the case of bacteriostatic normal saline, the presence of benzyl alcohol as a preservative and an anesthetic has been proposed as a suitable alternative for intradermal lidocaine. Other local anesthetics such as the topical lidocaine-prilocaine suffer from certain disadvantages as it is inappropriate for use on the day of the surgery, is not economical and needs to be applied 30 minutes prior to starting the IV for best results. The practice of using intradermal bacteriostatic saline instead of intradermal buffered lidocaine as the former was cost effective was adopted by a Midwestern community hospital as a pain management strategy during surgeries. However, the concern of the nurses in the hospital has been the lesser num ber of comparative studies that have determined efficacy of the two anesthetics. Additionally they have provided inconclusive evidence about the use of either intradermal lidocaine or bacteriostatic saline as an effective anesthetic prior to IV injection. Hence the present study aimed to determine the efficacy of the two anesthetics in order to bring about a practice change. ... However, previous studies have been inconclusive in comparing the effectiveness of the two anesthetics: intradermal lidocaine and bacteriostatic saline. Hence the present study was designed to compare the efficacy and determine the degree of pain using the two anesthetics and a randomized double-blind; quasi-experiment, and two-treatment, parallel designed study was conducted. The study was started after approval by the institutional review board. Both male and female same-day surgery patients in the age group of 18 to 80 were invited to take part in the study. The inclusion criteria were the presence of a physician’s order for a peripheral IV line and an ability to express the level of pain experienced. The sample size of the study included 150 adults who were admitted for same-day surgery between the months February and May. Two subjects required more than one venipuncture and in view of inaccurate reporting of the pain they were excluded from the study and others who were e xcluded include subjects allergic to lidocaine and others who had to take pain medication in the previous four hours. The degree of pain experienced by the subjects was measured using a modified verbal numeric rating scale (VNRS) in which the pain was recorded on a scale of 0 to 10. Buffered lidocaine for the study was prepared by a pharmacist using lidocaine and sodium bicarbonate and commercially available bacteriostatic saline was used. All the study subjects were blinded to the study solution and the basic demographics such as age, sex, race, IV location and catheter size were collected. The study protocol was explained to both the study participants and nurses who were responsible for the catheterization and informed consent was obtained from the participants.

United States trade policies and their effect on the automotive Essay

United States trade policies and their effect on the automotive industry - Essay Example The desolate outlook for the United States' auto industry comes as no surprise for most everybody.In the beginning of 2006 Ford Motor Company and General Motors, two of the "Big Three" automakers, announced staggering layoffs in the tens of thousands and debilitating year over year losses in the billions of dollars. In addition to these layoffs, both General Motors and Ford have planned for multiple plant closures and the selling off of controlling shares of assets or subsidiaries in their ongoing struggle toward profitability. These announcements come as a blow to the tenuous economic recovery of the United States.The recent trends regarding the economic recovery of the United States remains slow but promising. According to Employment Situations published by the U.S. Bureau of Labor and Statistics, the current average unemployment rate for the United States is 4.7%, (2006). The effect the impending massive job loss in the automotive industry will have on the unemployment rate and th e overall health of the nation's economy is uncertain.In the four years between 2000 and 2003, an estimated 5.2 million people lost their jobs. Over 2 million of those lost jobs were in the manufacturing industry ("Employment Situation," 2006). The cause for the ongoing decline in America's auto industry are many and range from increasing fuel prices and the growth of the global economy to poor product design and increased foreign competition. Although all of these issues are contributing factors in the decline of the American auto industry, none are as contentiously argued as issues of United States trade policies. According to Section 2102 Congressional Statement of Purpose on trade, there are 6 defining factors to U.S. Trade agreements (2003): To foster economic growth. Reduce or eliminate trade barriers. Trade 2 The establishment of fair and equal international trade. Provide protection of American industry and labor against "injurious" import competitions. To open market oppoutunites for U.S. commerce in non-market economies. To provide "reasonable" access of products too less developed countries or nations. In the process of attaining these goals U.S. trade polices have drawn harsh criticisms due to the nations' 2005 trade deficit in manufactured goods of $726 billion and to the apparent effect they have on the U.S. economy, its' labor force and worker rights and wages (Scott 2006). As the trade deficit in manufactured goods continues to rise, so too does the loss of jobs in the manufacturing industry. The United States finds itself unable to compete with low labor and production costs in foreign countries. For automakers such as Ford and General Motors, this has lead to the movement of production plants to outside the U.S. as well as the massive volumes of lay offs the industry is currently experiencing. The autoworkers that have been fortunate enough to retain their jobs face the issue of the downward pressure on wages and benefits that is caused by the rising trade deficit and the lower labor costs in foreign countries. Currently, the cost of labor in Mexico is the lowest of any developed nation (Bernard). Labor costs are one of, if not the number one, highest expense of any corporation. While moving U.S. production plants to Mexico creates jobs, increases the standard of living and stimulates the economy for that country, the U.S. labor force cannot compete with these low wages and benefits and therefore, lose bargaining power. The loss of bargaining power is exacerbated by the low level of government enforcement of labor laws in some foreign countries. In the United States this loss of bargaining power often results in the acceptance of lower wages and cuts to benefits and pension programs by U.S employees. Trade 3 While jobs are being exported to foreign countries such as Mexico, auto parts are being imported to the United States at an increasing rate. In 2004, the United States imported $77 billion

Participatory Research Design Essay The changing nature of the global business culture has necessitated various aspects of organizational behavior. This is the spirit of the overwhelming variables that define how employees interact and integrate with the corporate processes with the basic goal of meeting the corporate objectives and missions. Understanding the requirements of the organizational behavior is an important aspect which helps to align its procedures and processes in line with the behavioral conception within the corporation (Dan, 1998) The research team  The parameters that provide the best knowledge would involve carrying out a research study across various organizations aimed at learning the statutory components of the concepts of organizational behavior. This would involve a controlled dissemination of research team across the sample of selected corporations. The layout of the research process would involve the evaluation of the aspects that articulate within the fundamental concept of organizational behavior as an important factor in the success of the corporation. Investigating the issue and its assumptions. The concept of organizational behavior is chiefly incorporated at a diverse autonomy within different cases of organizations. This research study will therefore aim at studying the scope of influence of organizational behavior to the functionality of different organizations that differs in terms of capacity, functions, and managerial processes. The underlying assumptions will also be developed in terms of the result provision of the research process about what impacts are endowed by the concept of organization behavior (Dan, 1998) Developing an action pal and data collection strategies In order to collect the most reliable data, the researcher would pursue various methods of data collection strategies and methods that would help to yield the most reliable research results and outcomes. This would include the use of methods such as observation, questionnaire and survey. A stream of related data responses shall be collected through these methods which would then be used in arriving at rational conclusions and recommendations about the impact of organizational behavior to the contemporary functionality of the organization (Dan, 1998) Data analysis The research process would not be fully met until the collected data in passed through various methods of data analysis that would help to yield the most reliable results and findings. This could be through methods such as correlation, T-test, F-test, barographs, pie-charts and other significant methods of data analysis.

The Effects of Tax Avoidance

The Effects of Tax Avoidance Summary Tax avoidance has been a major menace in many governments worldwide. Therefore, this article will focus on tax avoidance by multinationals and the tax loopholes that motivate this unfair practice among nations. Companies such as Starbucks, HSBC, Google, Barclays bank and Amazon have been accused on more than one occasion of corporate tax avoidance. How do they go about this and get away with it? Do governments favor big corporations at the expense of domestic small and mid-level companies? At the end of this article, it will be clear and evident that indeed tax avoidance is morally wrong unless monitored under stringent government rules and regulations. In essence, this article focuses on the extent to which tax avoidance limits government expenditure (thus government spending) and the extent to which this problem affects the economy and society as a whole. The Moral violation of Tax Avoidance in a nutshell In these hard economic times of recessions and escalating unemployment in Europe and America, governments are implementing budget cuts in an effort to cope with national debts and the aftereffects of this global economic pandemic as a whole. Inflation reports have become the business norm of major mainstream media houses like CNN and BBC. It has become almost impossible to hear of a rise in employment levels or deflation in prices. What this means in essence is that as governments implement budget cuts, they also result to internal borrowing measures such as increasing taxes on goods and services in their respective local markets. At the end of the day, the ordinary hard-working citizen is left to grapple with how to balance an increasingly insufficient paycheck with ever-increasing prices of goods and services. It is because of this reason that tax avoidance shifts the tax burden from the evasive and tricky corporation to the honest middle and low income earning citizen. This is clearly a sign of tax bias practiced in broad daylight. The sad bit about this is that many governments don’t have stringent measures to punish such big ‘untouchables’. Is it that someone within is pulling the strings to ensure that justice isn’t upheld? Are these mysterious government entities ‘sufficiently compensated’ by tax avoiding multi-national corporations for a ‘job well done’? Because the interesting bit about tax avoidance is that it doesn’t amount to tax evasion. For instance, in 2011, the Google firm in the UK had amassed a whooping 395 million pound turnover. But as it turns out, the United Kingdom treasury only received 6 million pounds; an astoundingly tiny fraction of the profits. Similarly, Amazon had sales of 3.35 billion in the same year but contributed a mere 1.8 million pounds to the British Treasury . As absurd as these two randomly picked incidences sound, what these companies did was legal. Essentially, no laws were broken despite the moral absurdity of such obvious, draconian and potentially ‘tax evasive’ actions. Why aren’t there any laws to address such malice? Does it mean that someone is not doing his job and is being paid by these multinationals to keep quiet? Because at the end of the day, money is power thus more money translates to more power; to control, to manipulate, and eventually, to destroy economies and thus the society as a whole. The problem with tax avoiding firms is that their global market presence translates to humongous profits. This of course means too much money and thus too much power. And unfortunately, their power exceeds that of many government officials who are more than willing to do their devious bidding for that ‘extra pound’. Just taxation practice is based on the tenets of fairness and equality across the board not just within the circle of multinationals, but also within economies as a whole. The entire population has got to be convinced that the burden of tax is evenly spread across varying income levels and corporate profits. Tax avoidance by ‘the elite’ however brings about unnecessary tension due to economy class favoritism that’s making someone bear more unjust burden than he ought to. When the citizenry sees such tax injustices, then it’s bound to demand for the law to curb such dubiously lawful menaces. Facts supporting the moral absurdity of tax avoidance and how some countries are curbing the menace Tax avoidance potentially amounts to financial impunity. Incorporated tax laws with gaping holes and obvious loose ends are the biggest aids of tax avoiding multinationals (Samuel, 2005). In essence, firms are subject to business taxes whereas individual income earners are subject to personal taxes. For firms to practice tax avoidance in business taxes, they usually relocate their branches to offshore tax havens thus registering as alien business entities offshore. This makes firms avoid generating income onshore more and more with every alien business subsidiary that they register offshore. Thus, American based Google and Amazon avoid paying taxes in the UK by being classified and registered as non-resident business entities. This entitles them to avoid being taxed not only as resident businesses, but also as resident alien businesses. This is despite the fact that they enjoy all government rights and services similar to resident businesses in the host offshore havens. This in turn makes them pay less taxes to the American tax collector, also known as the IRS. FTSE 100 firms and Banks based in the UK are also key culprits in this menace, with 38% of their subsidiaries located in tax havens. High street banks such as The HSBC, Barclays bank, Lloyds and IBS have a combined total of 1,649 companies (Action Aid). A unanimous FTSE company is claimed to have transferred pricing payments so as to enable a whopping 100 million pound shift from subsidiaries based in developing country into tax havens where a ridiculously lower tax rate is incurred. A lack of stringent regulations on transfer pricing leaves loopholes for tax avoidance as taxable profits move to tax havens without breaking any law. Luxemburg, Liechtenstein principality, Delaware State, Nauru and Cayman islands are in fact the leading offshore tax havens that are menacingly unregulated and house profits that extend to dealings in drugs and arms trade. While in host offshore havens, these multinationals are usually private and secretive in regards to their finances thus raising eyebrows in regards to the integrity of their financial reports. The ignorance, inability and inexperience of developing countries such as China, India and Brazil to deal with the tax avoidance menace further aggravates the situation (Phyllis, 2003). This also brings in the problem of the inability to measure precisely how much worth of tax avoidance has been practiced in these countries. Multinationals are actually taking advantage of this by rapidly expanding their offshore investments to the detriment of offshore haven governments which don’t benefit from such investments as they ought to. For instance, the budget deficit for the Chinese government amounted to 3% of its GDP. Also in Mexico, it’s estimated that a whooping 40% of its entire citizenry might be untaxed (Gori, 2001). This goes to show how the citizenry in itself can be its own worst enemy when it comes to combating tax avoidance within resident businesses (Das-Gupta 1995). India has also been a victim too considering the fact that tax revenue percentage of GDP dropped sharply from 9.8% in 1991 to 8.95% in 1999. Exploding liberalization in these developing countries has sparked massive inflow of foreign investments. In fact, when direct foreign investment recipients are considered by merit, Brazil, China and Mexico have been at the zenith of this list for the past ten years. European, American and Japanese multinationals have been the biggest contributors to this direct foreign investment inflow thus playing key role in the growth of these developing economies. Interestingly enough, the local businesses have not enjoyed the chunk of foreign trade since related multinational firms in these tax havens control a majority of foreign trade (Chan, 1998). They do this by exercising sophisticated profit shifting mechanisms via manipulation of prices to dodge stringent measures enforced upon foreign exchange hence significantly cutting down on uncertain socioeconomic outcomes. In essence, intermediaries and basic raw materials are over invoiced while at the same time exports are underpriced thus enabling record tax avoidances. The Chinese open-door economic reform has made it maintain its enviable position as the greatest absorber of foreign direct investment (FDI) among developing nations to date. For instance, according to the 2002 United Nations Economic report, China got 28% of all FDI flowing into developing nations in 2001. The year 2002 was particularly good for FDI enterprises in China as 409,000 foreign investment enterprises were approved with a net worth of 425 million USD. Consequently, foreign direct investments in China have been key to its economic growth. The evidence is quite clear when it’s considered that 52% of China’s imports and 50% of its exports can be attributed to foreign investment enterprises (FIEs) within the country. Yet strangely enough, a resounding majority of these foreign investment enterprises is reporting record losses despite expanding at an astronomical rate. This automatically entitles them to avoid taxes. Tax avoidance escalated sharply in 2000 with a record $1.22 billion worth of noncompliance being reported ( Ming, 2001). This sparked a sharp rise in tax related audits in 2001. Brazil on the other hand exercises some fairness in taxation by taxing local and alien enterprises similarly. In fact, tax rules and laws applied to limited liability companies and corporations alike are similar irrespective of whether the firm is resident or non-resident. This is because foreign enterprises prefer taking the forms of corporations and limited liability companies. But interesting to note is the fact that limited liability companies aren’t obliged to disclose their financial reports to the public. However, corporations possess the comparative advantage of raising capital through IPOs (Initial Public Offers) of the share capital. Brazil has however come under sharp criticism as having a sophisticated taxing mechanism that hinders its business competitiveness globally. Despite this obstacle, the country has proven to be less naà ¯ve when it comes to dealing with tax avoidance incidences by adopting the principle of ‘If you can’t beat them, then join them.’. This is because it has taken advantage of tax avoidance tendencies by FEIs by offering tax incentives for establishment in distinct underdeveloped regions. For instance, a 50% tax cut on income is offered by the Brazilian government to industrial and agricultural enterprises that establish themselves in the marginalized and less developed North East and Amazon regions. In addition, a firm that sparks development in industrial technology has the right to an incentive on technical services and a 50% tax credit discount on royalties. Expatriates who have achieved the status of Brazilian residents are also obligated to pay a progressive income tax on their worldwide paycheck up to a maximum of 27.5%. This is because taxation upon individuals is implemented on cash basis. A factor to consider is that expatriates are considered residents if they’ve domiciled in Brazil for more than a year. Brazil also tackles tax avoidance by taxing a 25% withholding tax on nonresidents living in tax havens compared to a 15% withholding tax on those who don’t. This is because nonresidents are entitled to royalties, dividends and interest. When it comes to transfer pricing, proper laws that are compatible with OECD have been enacted to ensure the proper determination of import and export prices. Conclusion The rationale behind payment of taxes is that we owe a duty to three entities; namely to the state, the community, and last but not least, to God. Therefore in as much as tax avoidance is morally unjustified and inexplicable, it is distinctively clear that governments worldwide should take the initiative to curb this menace. Better still, governments can take advantage of the situation and enact sound laws that create morally acceptable tax avoidance, such as tax incentives and tax breaks offered by the Brazilian government to develop marginalized areas and to spark innovative development. That way, an equitable tax basis is maintained and society is generally happy to share the burden of tax on the basis of a non-secretive, convincingly just and morally acceptable manner.

Why is the Holocaust Still Relevant Today in Wiesels Night Essay

The Holocaust is over and has been for about sixty years, so why are we still talking about it? Why is it still relevant in our world today? The world should have learned from its mistakes, but the sad part is that we did not. No, Hitler is no longer killing millions of innocent men, women, and children, but we are still just still just as cruel only in different ways. Night is Elie Wiesel’s factual account of his experiences in the holocaust. He brings us to a world in which not many people want to go. He tells us the true story of what really happened in Nazi concentration camps. Elie Wiesel, a holocaust survivor chooses to tell his story and begins to teach an entire generation the dangers of ignorance and hatred. Just by telling his story, just by writing it down, Wiesel is helping to educate people about what atrocities happened in the concentration camps. It tells us about how he was stripped down of his human rights. â€Å"A7713?’ ‘That’s me’† (51 Wiesel). Wiesel talks about how he was degraded as a human being. He is not even considered a person anymore. He is dehumanized and reduced to little more than a number. An example of the harshness is the selections, where he saw people who slept beside him the night before, get sentenced to death. He makes it clear that just because you passed an examination, doesn’t mean you’re safe. You might have been lucky this time but there will be a next time and they can just as easily give you death. He is basically saying that if you want to survive, then you had to prove yourself strong and healthy, but basically it was all on luck. This teaches us how cruel the Nazis were to the people in the concentration camps. Every selection would be dreadful and you had no way of knowing wheth... ...spoke about the concentration camps while they were going on, then that could have made the difference. All you really need is one person to start and others will follow. There was a reason why Wiesel made it out of the camps, and millions of others did not. He made a difference. He educated so many people of the pains of the Holocaust. Since we now know about it, we should not be ignorant and pretend that there is no other problems in our world, because there is. Now that we know this and we know what has happened in the past, we should do everything we can to prevent this from happening in the future. We determine the future, we can either ignore the problems of others including in other countries and the same thing might happen to us, or we can choose to do something about it and try to eliminate hatred and make sure that no one will have to experience it again.

Globalisation and the Australian Economy Essay -- essays research pape

The Impact of Globalisation on the Australian Economy Globalisation is not new. Australia has been involved in trade, investment, financial flows, technology transfers and the migration of labour since its foundation as a colony. What has changed is the size, direction and influence of these transfers, especially since 1980. There are a number of factors that have aided this transformation. They include: †¢Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The expansion of new markets – foreign exchange and capital markets are linked globally. They operate 24 hours a day with dealings any where in the world possible in real time. Financial deregulation and the floating of the Australian dollar since 1983 intensified the impact of globalisation on the Australian economy. †¢Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  New technology and the tools of globalisation – the internet, email, mobile phones, media and communication networks have all sped up the process of globalisation. They have increased the spread and speed of knowledge transfer and communication. Australian consumers can buy products from any nation in the world, transfer funds between accounts or purchase shares in any major market. Australian businesses can market their products at a fraction of the cost and be exposed to a global market place of competition. This potentially is the closest we will ever come to the perfect market. †¢Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  New institutional players – The World Trade Organisation (WTO) has growing authority over national governments, as does the IMF with its restrictions and controls it can impose on nations requiring assistance. Multinational corporations have more economic power than many nations. Hedge funds and financial dealers are able to manipulate financial flows and subsequently exchange rates, leaving nations helpless in their wake. This in turn renders traditional economic policy tools virtually useless. †¢Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  New rules and restrictions – Multilateral agreements on trade, services and intellectual property rights, backed by strong enforcement mechanisms, reduce the scope for national governments to develop their own economic policies. What is Globalisation? Globalisation is the growing economic interdependence among nations as reflected in increasing actual movement across nations of: †¢Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Trade †¢Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Inv... ...ly be quite effective at pushing the Australian dollar down by selling the currency, it is very limited in pushing it up. The RBA only has its limited foreign reserves to buy the Australian dollar. The value of Australia's foreign reserves fell from $22billion US in December 1999 to $16billion US in September 2000. The amount of Australian dollars traded in one day in Australia's foreign exchange market exceeds its total foreign reserves. As was seen in the Asian crisis in 1997 in Thailand, running down foreign reserves will not always halt a currency decline. The US Federal Reserve is probably the only central bank that can strongly influence the decisions of fund managers. The financial traders and dealers seek a low inflation, low interest rate, low current account deficit, high growth, budget surpluses and small public sector. If the Government does not achieve these policies, the markets will punish it. If they do achieve them, the markets may still punish them. Any way you look at it, Australia is integrated into the globalised world economy and is dependent on the activities and policies of globalisation. Australia’s future will move with the ebb and flow of globalisation.

Cardiovascular Review Sheet Essay

The following questions refer to Activity 1: Studying the Effect of Flow Tube Radius on Fluid Flow. 1. At which radius was the fluid flow rate the highest? 6.0 mm 2. What was the flow rate at this radius? 1017.2 mmHg 3. Describe the relationship between flow rate and radius size. The relationship between the flow rate and the radius size is direct with the formula flow rate=radius to the fourth power. 4. What happens to blood vessels in the body if increased blood flow is needed? The blood vessels dilate to increase the flow to where the blood is needed in the body.  The following questions refer to Activity 2: Studying the Effect of Viscosity on Fluid Flow. 5. At what viscosity level was the fluid flow rate the highest? 1.0 6. Describe the relationship between flow rate and viscosity. The relationship is inversed; meaning a fluid that has a high viscosity has a slow flow because it resists the flow. Fluid that has a low viscosity will flow faster because it is less resistance to the flow. 7. Was the effect of viscosity greater or less than the effect of radius on fluid flow? Why? Less, the radius of blood vessels effect flow more because the large blood vessels allow more blood to flow through regardless of viscosity. 8. What effect would anemia have on blood flow? Why? The effect would cause a decrease in blood flow because anemia causes the blood vessels to constrict. The following questions refer to Activity 3: Studying the Effect of Flow Tube Length on Fluid Flow. 9. At what flow tube length was the flow rate the highest? 10mm 10. Describe the relationship between flow tube length and fluid flow rate. The relationship between flow tube length and fluid flow rate is when the tube length is shorter the faster the flow. 11. What effect do you think obesity would have on blood flow? Why? When blood vessels lengthen, they cause a flow of blood to decrease, because there is only roughly 7 miles of blood vessel for every 1 pound of fat. When someone gains weight, the body has to produce more blood vessels which lead to decreased blood flow and high blood pressure. The following questions refer to Activity 4: Studying the Effect of Pressure on Fluid Flow. 12. What effect did increased pressure have on the fluid flow rate? The effect that increases pressure have on the fluid flow rate is that the greater the pressure the faster the flow. 13. In the body, where does the driving pressure for fluid flow come from? The driving pressure for fluid flow comes from the heart. Pump Mechanics The following questions refer to Activity 5: Studying the Effect of Radius on Pump Activity. 14. What happened to the flow rate as the right vessel radius was increased? When the right vessel radius was increased the flow rate increases. 15. What happened to the rate (strokes/min) as the right vessel radius was increased? Why did this occur? Stroke rate increased as the right vessel radius increased because the beaker emptying time decreased. The following questions refer to Activity 6: Studying the Effect of Stroke Volume on Pump Activity. 16. At what stroke volume tested was the pump rate the lowest? 120 17. Describe the relationship between stroke volume and pump rate. The relationship between stroke volume and pump rate is that as stroke volume increases, the pump rate decreases. This happens because this is an inverse relationship. 18. Use the relationship in question 17 to explain why an athlete’s resting heart rate would be lower than that of a sedentary individual. An athlete has a higher stroke volume than a sedentary individual, meaning the athlete needs fewer heart beats to achieve the same cardiac output. The following questions refer to Activity 7: Studying Combined Effects. 19. How did decreasing the left flow tube radius affect pump chamber filling time? Hint: Look at the change in flow rate and relate this to filling time. When decreasing the left flow tube radius to affect the pump chamber filling time is by decreasing the left flow tube caused by an increase in the pump chamber filling time. 20. When the left beaker pressure was decreased to 10 mm Hg, what happened to the filling time? After the left beaker pressure was decreased to 10mm Hg, the filling time increased in response to decreased pressure in the left beaker. The following questions refer to Activity 8: Studying Compensation. 21. With the right flow tube radius decreased to 2.5 mm, what conditions did you change to bring the flow rate back to normal? The conditions that I changed to bring the flow rate back to normal were the increase left flow tube radius, increase pump pressure, increase left baker pressure and decrease right beaker pressure. 22. A decreased tube radius is analogous to atherosclerosis (plaque formation in vessels). Describe the effect this would have on resistance in the arterial system and how the human heart might compensate for this change. Atherosclerosis causes an increased atrial resistance which causes the heart to compensate by increasing pumping pressure.
