Orange Juice Titration Essay Example | Topics and Well Written Essays - 750 words

Orange Juice Titration - Essay Example Ascorbic acid ascorbic acid (also known as Vitamin C) is antioxidant and in presence of oxidizing agent it turns into dehydro-ascorbic acid [2]. Earlier experiments have shown that exposure of orange juice to oxygen lead to decrease in amount (concentration) of ascorbic acids and browning of orange juice [3]. No such effect is observed when orange juice is exposed to light [3]. While another research showed that the oxygen does not accelerates non enzymatic browning of orange juice [4]. This research paper tries to analyze the effect of oxygen and light on orange juice and thereby tries to resolve the ambiguity. Hypothesis Null Hypothesis 1: Oxygen does not affect the lifespan of orange juice or vitamin C in the juice. Alternate hypothesis: Oxygen affects the lifespan of orange juice or vitamin C in the juice Null Hypothesis 2: Exposure to light does not affect the life span of orange juice or vitamin C in the juice. Alternate hypothesis: Exposure to light affects the lifespan of ora nge juice or vitamin C in the juice. Claim Exposure to oxygen reduces the shelf life of orange juice. Exposure to light reduces the shelf life of orange juice. ... exposed to air (not exposed to light) 7.666667 10 7 Fresh 0.1. exposed to light 18.66667 23 14 Concentration values of ascorbic acid of different samples achieved from titration (concentration = x*10^-4) P values (T-Test) Fresh OJ.

Fresh 0.J. exposed to light 0.03491 Probability of type 1 error while rejecting null hypothesis using students T-test. Bar graph depicts minimum, mean and highest observed concentrations of ascorbic acid in the three samples of orange juice. Evidence It was observed that the mean concentration of ascorbic acid in fresh OJ (0.00320) was much higher than the mean concentration of ascorbic acid in non-fresh OJ (0.00077). Mean concentration of ascorbic acid in fresh OJ exposed to light (0.00187) was more t han mean concentration of ascorbic acid in both non fresh OJ and less than fresh OJ. The variation in concentration of ascorbic acid was highest in Fresh 0.J. exposed to light (2.03333E-07) and was lowest in Non-fresh OJ exposed to air (not exposed to light) (4.33333E-08). T test showed that population Fresh OJ (not exposed to light) and population Non-fresh OJ exposed to air (not exposed to light) were not same. This could be stated with more than 99% accuracy. T test also showed that population Fresh OJ (not exposed to light) and population Fresh 0.J. exposed to light were not same. This could be stated with almost 98% accuracy. Conclusion It was found that the ascorbic acid concentration in orange juice decreased when it was exposed to both light and

International business activities - Essay Example ic transaction processes and when they unfold on the international, cross-cultural level, they become even more challenging (Neslin and Greenhalgh, 1983; Gulbro and Herbig, 1994; Gilsdorf, 1997; Foroughi, 1998; Kumar, Markeset and Kumar, 2005). This is largely because, within the context of IB, negotiations move from the level of reaching an agreement between individuals who have comparable world views to reaching a compromise between cultures whose representatives may have divergent world views, including conflicting values (Bjerke, 2006). The implication here is that IB paradigms must be culturally sensitive and adaptable, on the one hand, and culturally-informed, on the other (Bjerke, 2006). Turning to TQM, one finds that it embrace cultural sensitivity as a direct outcome of its consumer focus (Collins, 2005). The paradigm itself is premised on the supposition that if corporations are to succeed in diverse cultural environments and to successfully engage in cross-cultural negotia tions, they have to embrace the culture of the environment in question, be it of their consumers or their business partners, and redefine themselves as insiders, rather than outsiders (Collins, 2005; Bjerke, 2006). Its embrace of sociology, therefore, marks TQM as highly well-suited to international businesses and, as a root discipline, is fundamental to the success of IB. As international business unfolds within the context of a global, as opposed to a national economy, international economics emerges as another fundamental root discipline. IB scholars acknowledge the presence of a synergetic and dynamic relationship between international economics and international business. On the one hand, IB is inextricably dependant on the health of the global economy for its own development,... International business activities International business, which has both been facilitated by and imposed upon firms by the advent of globalization, may be briefly defined as the global exchange of goods and services, or cross border economic transactions. As a number of scholars have quite rightly pointed out, international business is the internationalization and the concomitant expansion of the scope of traditional business activities. Within this context, it may also be defined as a natural evolution in the development of the scope of business activities, from the intra-tribal to the inter-tribal, from the intra-township to the inter-township and from the national to the international (Wiles and Wiles, 2005; Carbaugh, 2005; Marx, 2006; Sundaram and Black, 2007). The implication here is that while international business is founded upon the same precepts and principles of traditional/national business and, accordingly, withstands adherence to the same management paradigms, the significant expansion of its parameters and sphere of activities necessitates the embrace of sociology, international economics, politics and linguistics, to name but a few disciplines. On the basis of the foregoing discussion, TQM emerged as an ideal international business paradigm, largely because it embraces and addresses IB’s concerns. This was demonstrated through reference to three of its root disciplines, international economics, sociology and organizational theory.
