Effect of lowering temperature in tissue and organ preservation Research Paper

Effect of lowering temperature in tissue and organ preservation - Research Paper Example Enzymes in tissues and organs dissociate through inactivation because of cold-related propensities. Some enzymes are intrinsically affected by cooling. Reducing the temperature increases trans-membrane diffusion of solutes from minute ions to expanded molecules (Fuller et al., 2014). Hypothermic Machine Perfusion Preservation This preservation method was developed to enhance the quality and time of preservation of kidneys. The method allows the movement of oxygen to the tissues to enable ATP synthesis. The perfusion of the fluids aids in the transportation of oxygen through the fluids to essential areas of the organ (In Kirk, 2014). The perfusion process is positively impacted when the temperatures are regulated to certain limits. Even though the reduction of temperatures can have certain side effects, the preservation viability is immensely enhanced. Oxygen Persufflation The method employs gaseous oxygen in improving the viability of an organ for transplant. For instance, oxygen is bubbled through a vasculature that is then released through minute proliferations at the organ's surface. The method is effective in liver preservation because of its homogenous distribution of oxygen. The method has incredible capabilities of recovering the DCD organs (In Kirk, 2014). The two methods are critical in reducing the metabolic and chemical reactions that can otherwise affect the normal establishment of an organ. The flow of oxygen within the organ is the principal foundation of employed by the methods of preserving organs and tissues.

Improving Decision Making - Essay Example The company's defence that the price was part of a "random price test" and could be refunded solidified the suspicion further it was into dynamic pricing activity, as similar instances were far too many. Just like the company offered $51 less by Amazon than its own usual price on a dedicated bargain website (ramasastry, cnn.com). An analysis can be done from figures provided as quarter wise sales data, of a particular book sold through this portal, (Niles, R., ojr.org). It shows that the company had skimmed high earnings through a dynamic pricing policy in the first quarter sales. Eleven and twelve copies of the same book were sold at the prices of $11.02 and $11.50 each respectively while in the second quarter the same book sold sixteen and eleven copies each at the prices of $11.02 and $11.70 respectively meaning a highly elastic nature of the book's demand can be computed at a elasticity demand- coefficient of two, which is greater than unitary. It may be noticed here that there was an increase in sales of the books even when the prices charged were higher. If total earnings based on variable pricing quarter - on - quarter are considered , then they range from 15% to almost as high as 40%. This is where the marketers like Amazon.com have the opportunity to maximize their earnings from unsuspecting custome rs through their dynamic pricing strategy as even against a higher price Amazon sold more number of copies. The remaining quarters also showed a similar effect. Benefits & disadvantages The benefits of dynamic pricing comprise of stimulating demand which helps to churn inventory quicker translating into more revenue and greater margins. The new focus is on target pricing, with technology profiling the price sensitivity of customers to determine the selection of groups which can be discriminated on pricing. . It is believed by the company to help in maximizing the total revenue for the company. The associates and partners of Amazon even share historical data of their dynamic pricing. (Liquid commerce, information-age.com). The disadvantages are also quite a few such as customer loyalty start disappearing once regular customers find out that they are being overcharged in contrast to a new customer offered a lower promotional price . This could drive customers to bargain counters where everyone is treated fairly and there is no discrimination through dynamic pricing. The other drawback of this method may be a legal threat incase it appears that the firm is violating an titrust laws or not having a fixed price policy. Conclusion However, it may be an end of an era of list prices where the product life cycle is short, (Strategic interactive marketing, managing change.com), the distance minimized and delivery lead times lessened with the help of technology and modernization. Industry experts have reportedly observed dynamic pricing to be a boon to high fixed and low marginal cost industries and also as a necessity for e commerce (Weiss, R., M. & Mehrotra, A., K.,

How might developments in e-mental health influence mental health nursing practice in the coming decade - Essay Example ic dimensions, for instance, personalized interventions through the use of the handy gadgets such mobile phones is set to open even more ways of monitoring patients’ symptoms and/or condition in real time, allowing for early, prompt intervention and the prevention of relapse in cases of emergencies (Christen & Petrie, 2013b). Accordingly, the advances will leverage professional roles, reserving such for more complex cases as e-mental health gears up to cater for milder problems forming the bulk in the area discussed herein. With advanced, automated applications for monitoring situational risks such as disaster hit regions, opportunities exist for timely interventions to avoid overwhelming casualties. To be certain, it is already much easier to disseminate mental health information online, more particularly through the social media (Christen & Petrie, 2013a; Christen & Petrie, 2013b); a fact which is set to get even more rapid over significantly larger populations in years to c ome, particularly with regards to the collection and/or processing of large amounts of data from dispersed populations by the nursing professionals around the world. Arguably, the direct informational access online is already changing the practioner-consumer power arrangements towards the latter, with consumers sharing information of what treatments works, the professionals providing the best services, as well as the grey areas that still need research amongst themselves (Jorm, Morgan, & Malhi, 2013). As Jorm, Morgan, & Malhi (2013) concludes, quite a number of issues remains to be solved to secure the advantages brought about by e-mental healthcare systems. That though such technologies continue to easen the collection and the dissemination of information, which e-mental health is all about, the impending implications for this very unique health sector remains largely unknown, for the developments would have to undergo satisfactory experimentation to ensure absolute

Technical Efficiency of China's Banking Industry Literature review

Technical Efficiency of China's Banking Industry - Literature review Example Nonetheless, most economies have been able to exhibit resilience and remained stronger. Economic turbulences and dynamisms have affected different industries within various global economies. China’s banking industry has not been spared from such turbulences and dynamisms hence the need to analyze its technical efficiency. The following chapter provides a chronological description and critique of relevant theories in respect to technical efficiency within China’s banking industry. The chronological description and critical review entails empirical papers linked to the concept of the study. Different theories of efficiency with respect to technical efficiency are discussed within this chapter. 2.2 Overview of China’s Banking Industry China has being operating economic and financial system on the basis of social principles until 1978. Amazingly, the People’s Bank of China (PBC) had for a long time been in-charge of issuing currencies as well as being the fina ncial hub of all the economic plans of China. After 1978, China realized the need for serious economic and financial reforms. The objective of such reforms was to increase economic and technical efficiency of financial and economic sectors within the country (Jiang, 2001). Jiang (2001) adds that China aimed at enhancing resource allocation through such reforms. Albeit gradual, serious reforms were carried out in major sectors of the economy, banking being the main recipient (Adams, Berger, & Sickles, 1999). China decided effect the reforms in two main stages; from 1979 to 1992 and from 1993 to the present time. The first stage was characterized by development of two tier banking systems; People’s Bank of China (Central Bank) and four state-owned banks that included Bank of China (BOC), China Construction Bank (CCB), Agricultural Bank of China (ABC), and Commercial Bank of China (CBC). Despite high degrees of functional segmentations, these banks were permitted to accept depos its and offer credit facilities to households and corporate organizations by 1985 (China Daily, 2006). The first stage formed the basis of further reforms, which was characterized with development of small and medium sized commercial banks. The main reason for allowing entrance of commercial banks within Chinese banking system was to enhance competition, which was aimed at providing high quality and differentiated services and products (Jiang, 2001). Examples of small and medium commercial banks created during this period included CITI Industrial Bank, Guangdong Development Banks (GDB), China Merchants Bank (CMB), Hua Xia Bank (HXB), and China Everbright Bank (CEB) (China Daily, 2006). Notably, most of these commercial banks were joint-stock owned unlike the previously mentioned state-owned. The second stage, which was flagged off by State Council in 1993 saw various decisions made within the financial system reforms (Leigh and Podpiera, 2006). In this stage, the main aim was to enh ance c

The Fair Value change with respect to the Financial Crisis Essay Example for Free

The Fair Value change with respect to the Financial Crisis Essay The world has come under the grips of a global financial crisis. Such events with big accounting and financial impacts are few and forlorn but when they do come, they bring with them uncertainty and pessimism as well as the desire to bring about some change so as to curtail such events from taking place in the future. With regards to standard setting, this is being achieved through the debate surrounding fair value reporting. Banks and many other troubled financial institutions that bore the brunt of the tidal wave of the credit crunch are calling on the Financial Accounting Standards Board to ease their stance in relation to fair value accounting whereas investors and financial analysts are standing forward to block this move. Fair value accounting had been brought into place after much deliberation by standard setters over the years. Its application worldwide was a reflection of the need for financial statements to reflect the assets held by firm on their balance sheets at prices they could be realized at today in the markets, in a fair deal and an arm’s length transaction. This was recognized as something that provided a fair outlook of the current financial position of banks and other institutions and was held very closely guarded by the FASB (Katz 2009). The chairman of the board’s adherence to the need for fair value to continue and his defense of the methodology in a testimony before the US House of Representatives Financial Services Subcommittee in March of 2009 is a strong indicator of where standard setters actually fall in the debate. However, in April of 2009 the board voted to relax the fair value rules under strong political pressure and in an uncharacteristically rapid fashion for a body that is known to engage in long debates and continued discussion before enacting any changes in the accounting standards. This change has sparked unique responses from the two sides of the debate. Banks and other financial institutions have been delighted with the measure. They had come out in open opposition to fair value rules following the financial crisis stating that it unfairly influenced their accounts. They argued that the use of the fair value criteria resulted in them show items in their balance sheet as significantly lower value than they would be actually realized at, thereby giving them a relatively bleak financial outlook with very pessimistic figures (Katz 2009). The impetus for the move was that if this could be alleviated to some extent, then banks would be better able to report their true financial situation and reduce some of the write-offs that have wrecked the industry, thereby even putting them in a better position to issue more loans and perhaps precipitate faster recovery from the crisis. The optimism of the banks with regards to the proposed shift by the FASB was reflected in the markets as the stocks of major banks such as Citibank and Bank of America went up in the New York Stock Exchange. Investors and financial analysts however have been strongly against the move being put forward by the FASB in April. They argue that fair value accounting results in showing the actual financial health of the financial institution and changing the rules would result in a distorted perspective being put forward to the investors. It is further seen as being a highly transparent view of the financial health as it leads to assets being valued at the amount they could be traded today which is a reflection of the economic times as well as the trend of decision making that has been going on in the industry. Thus after the changes have been brought into place, investor group are showing growing unhappiness at what is viewed as something potentially harmful. They were also wary of the involvement of political pressure in the move, which if freely allowed to influence international standard setting would compromise the integrity of the field and harm investor confidence as well. The FASB did come out in support of the investor though by additionally requiring more disclosure of the methodology employed by firm for valuation after the FASB allowed them significantly more room for judgment regarding it through relaxation of the rules. It further did not allow the financial institutions to apply the changes retrospectively which would have altered their 2008 statements as well. It also restricted the application of some proposed changes such as those relating to valuing impaired securities by keeping it only for debt securities. FASB’s shift has been in a manner that can be considered characteristically different from its formal procedure. The world of standard setting has been slow with prolonged discussions before any changes are brought forward. With regards to the current change, it was made considerably rapidly by bringing in remarks for discussion, pursuing a review of one day and then handing out the proposed changes which is a testament to the tricky financial times and political pressure. The shift that was brought about included allowing the firms considerable room for â€Å"judgment† with regards to gauging prices of some of their investments represented on the financial statement as well as those for mortgage backed securities (Katz 2009). This did meet with opposition from other bodies such as the CFA Institute and investors groups, the former arguing that such arbitrary changes damage their credibility while the latter is in woe of the difficulties investors will face now. They have even gone out to condemn to some extent the U-turn taken by the chairman of the FASB whereby he shunned the changes proposed to fair value methodology in front of congressional subcommittee but then agreed to put in place the same measures hardly a month later. Thus it can be seen that the current financial crisis has altered the direction standard setting in accounting has taken. It can be said that this is a fairly damaging trend. While it may result in short term gains for fighting the financial crisis and help shore up loans and lending, it could be damaging in the long run as political pressures and advocacy groups may damage the credibility and transparency of standard setting and financial statements presentation. It could also be adverse for the investor who may not trust the standards as providing fair information and affect their behavior. Furthermore, the integrity of the institute may well have been compromised in this case by the u-turns being adopted by the chairman of the FASB. Bibliography Katz, Ian (2009, April 2).

Patterns Within Systems Of Linear Equations

Patterns Within Systems Of Linear Equations The purpose of this report is to investigate systems of linear equations where the systems constants have mathematical patterns. The first system to be considered is a 2 x 2 system of linear of equations: In the first equation, the constants are 1, 2, and 3 in that order. It is observed that each constant is increased by 1 from the previous constant. Thus, the constants make up an arithmetic sequence whereby the first term ( U1 ) = 1, and the difference between each term ( d ) = 1. Hence, the general formula is Un = U1 + (n-1)(1) where n represents the nth term. U2 = U1 + (n-1)(d) U3 = U1 + (n-1)(d) 2 = 1 + (2-1)(1) 3 = 1 + (3-1)(1) 2 = 2 3 = 3 In the second equation, the constants are 2, -1, and -4 in that order. It is observed that each constant is increased by -3 from the previous constant. Thus, the constants from this equation also make up an arithmetic sequence whereby U1 = 2 and d = -3. Hence the general formula is Un = U1 + (n-1)(-3). U2 = U1 + (n-1)(d) U3 = U1 + (n-1)(d) -1 = 2 + (2-1)(-3) -4 = 2 + (3-1)(-3) -1 = -1 -4 = -4 To further investigate the significance of these arithmetic sequences, the equations will be solved by substitution and displayed graphically. x + 2y = 3 2x y = -4 x = 3- 2y y = 2x + 4 x = 3 2(2) y = 2(3 2y) +4 x = -1 5y = 6 + 4 y = 2 On the graph, both lines meet at a common point (-1,2) where x = -1 and y = 2. The two linear equations have a solution of x = -1 and y = 2, proven analytically and graphically. However, this pattern may be only specific to this 2 x 2 system of linear equations. Therefore, other 2 x 2 system of linear equations following the same pattern of having constants forming arithmetic sequences will be examined as well. Another 2 x 2 system of linear equations to be considered is: The constants of these equations are 3, 6, and 9, and 4, 2, and 0 with a difference of 1 and -2 respectively. The equations were then re-written as: And plotted on a graph. The common point of both equations is (-1,2), with x being -1 and y being 2. Therefore the common point has been proven both analytically and graphically to be (-1,2). Another example is: The constants of these equations are -3, 1, and 5, and -2, -6, and -10 with a difference of 4 and -4 respectively. The equations were then re-written as: And plotted on a graph. The common point is (-1,2). Thus it is both proven analytically and graphically that the common point is (-1,2). Another example is: The constants of these equations are 3, 2, and 1, and 2, 7, and 12 with a difference of -1 and 5 respectively. The equations were then re-written as: And plotted on a graph. The common point is (-1,2). Thus it is both proven analytically and graphically that the common point is (-1,2). Another example is: The constants of these equations are 5, 12, and 19, and 1, -5, and -11 with a difference of 7 and -6 respectively. The equations were then re-written as: And plotted on a graph. The common point is (-1,2). Thus it is both proven analytically and graphically that the common point is (-1,2). From the examples of 22 systems of linear equations, a conjecture that could be derived is: The solution for any 22 system of linear equations with constants that form an arithmetic sequence is always x=-1 and y=2. The general formula of such equations could be written as: Whereby represents the first term for the first equation and represents the first term for the second equation with a common difference of and respectively. The equations are then solved simultaneously: Therefore, it is proved that the solution for a 22 system of linear equations with constants that form an arithmetic sequence is always x = -1 and y = 2. However, the possibility of a 33 system exhibiting the same patterns as the previous 22 systems examined has not been discussed. Hence, this investigation will extend to 33 systems as well. Here is an 33 system: The for the first equation is 3 and the is (5-3)= 2. The for the first equation is 1 and the is (-4-1)=-5. The for the first equation is 4 and the is (7-4)=3. Gaussian Elimination method will be used. Change R3 into 4R2-R3 Change R2 into 3R2-R1 Change R3 into 23R2-17R3 The third row/R3 has all 0 which means that there is no one unique solution but infinite solutions. Therefore, in R2 We will let where k is a parameter To find other solutions, will be substituted in the other equation The solutions to this 33 system of linear equations with the pattern of constants making up an arithmetic sequence are , , and where is a parameter. Here is another 33 system: The for the first equation is 2 and the is (3-2)= 1. The for the first equation is 5 and the is (5-3)=-2. The for the first equation is -3 and the is (4-(-3))=7. The equations were put into matrix form and row reduction was done on the Graphic Design Calculator. The third row is all 0. This indicates that there is no unique solution, but infinite solutions instead. Assuming that whereby is a parameter, The solutions to this 33 system of linear equations with the pattern of constants making up an arithmetic sequence are , , and where is a parameter. Another: The for the first equation is 4 and the is (-2-4)= -6. The for the first equation is 1 and the is (5-1)=-4. The for the first equation is 2 and the is (7-2)=5. The equations were put into matrix form and row reduction was done on the Graphic Design Calculator. The third row is all 0. This indicates that there is no unique solution, but infinite solutions instead. Assuming that whereby is a parameter, The solutions to this 33 system of linear equations with the pattern of constants making up an arithmetic sequence are , , and where is a parameter. Here is another 33 system: The for the first equation is 4 and the is (-4-4)= -8. The for the first equation is 2 and the is (-1-2)=-3. The for the first equation is 6 and the is (14-6)=8. The equations were put into matrix form and row reduction was done on the Graphic Design Calculator. The third row is all 0. This indicates that there is no unique solution, but infinite solutions instead. Assuming that whereby is a parameter, The solutions to this 33 system of linear equations with the pattern of constants making up an arithmetic sequence are , , and where is a parameter. The for the first equation is 7 and the is (20-7)= 13. The for the first equation is 20 and the is (3-20)=-17. The for the first equation is 6 and the is (-5-6)= -11. The equations were put into matrix form and row reduction was done on the Graphic Design Calculator. The third row is all 0. This indicates that there is no unique solution, but infinite solutions instead. Assuming that whereby is a parameter, The solutions to this 33 system of linear equations with the pattern of constants making up an arithmetic sequence are , , and where is a parameter. From these examples, a conjecture can be made. A 33 system of equations that have constants that form an arithmetic sequence will have infinite solutions that will be in the form of , , and where is a parameter. This is proven by the general formula: Being solved by using Gaussian elimination rule: Change R3 into R3-R2 Change R2 into R2-R1 Change R3 into Change R2 into Change R3 into R3-R2 R3 has only zeroes/0. This means that there is no unique solution but infinite solutions instead. Assume whereby is a parameter, Through substitution, The solutions for this 33 system are , , and , proving the conjecture true. Other than systems of linear equations that contain arithmetic sequences, other types will be investigated. Lets consider this 2 x 2 system: In the first equation, the constants 1, 2, and 4 make up a geometric sequence whereby the first term (U1) is 1 and each consecutive term is multiplied by a common ratio (r) which in this case is 2. à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ U2 à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ U3 In the second equation, the constants 5, -1, and make up a geometric sequence whereby U1 = 5 and r = . à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ U2 = à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ U3 The equations can be rewritten in the form of as: For the first equation, and . For the second equation, and.. The relationship between and appears to be that one is the negative reciprocal of the other. In any case, more examples of similar linear equations will be needed to thoroughly investigate the patterns. The equations will be solved by substitution: Another example: In the first equation, the constants 3, 12, and 48 make up a geometric sequence whereby the first term (U1) is 3 and each consecutive term is multiplied by r which in this case is 4. à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ U2 à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ U3 In the second equation, the constants 3, -1, and make up a geometric sequence whereby U1 = 3 and r = . à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ U2 = à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ U3 The equations can be rewritten in the form of as: For the first equation, and . For the second equation, and.. The equations will be solved using substitution: Another example: In the first equation, the constants 7, 42, and 252 make up a geometric sequence whereby the first term (U1) is 7 and each consecutive term is multiplied by r which in this case is 6. à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ U2 à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ U3 In the second equation, the constants 2, -1, and make up a geometric sequence whereby U1 = 2 and r = . à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ U2 = à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ U3 The equations can be rewritten in the form of as: For the first equation, and . For the second equation, and.. The equations will be solved by using substitution: From observing all three systems, it is found that the relationship between and appears to be that one is the negative reciprocal of the other. But it can also be said that . The general formula of such equations could be written as: Whereby represents the first term for the first equation and represents the first term for the second equation with a common ratio of and respectively. The equations are then solved simultaneously: So is the result of one ratio subtracted from the other. is the product of the common ratios from both linear equations.
