Whatever power relations manifested in different aspects of the development paradigm are perceived by post-developments. Basically‚ the Post-development also has two distinct and entwined concepts: knowledge and power (Jakimow‚ 2008). Post-developmentists argue that the power of this world is in the hands of developed countries. Because power is crucially dominant factor‚ the aim of the post-development is successfully to transfer power from the hands of outside ‘expertized’ paradigm that has been

da Alvarenga Lab Partner: Keren Appiahene Mussie Gide 10 September 2016 Experiment 2: Acid- Base Extraction Separation of an Organic Acid‚ a Base and a Neutral Compound Introduction: The extraction technique is often used in the organic lab to separate organic compounds from mixtures. One type of an extraction technique is the acid-base extraction‚ which is used to separate organic compounds from a mixture based on their acid-base properties.1 There are certain principles that must be taken into

Lab 12: Titration of Acetic Acid in Vinegar Abstract: To lesarn how to titrate chemicals in a lab. Also to be able to determine the concentration of an acetic acid solution. Purpose: To learn how to titrate‚ and calulate the concentration of an acetiuc acid solution. In this case the concentration of vinegar‚ which is diluted acetic acid. Hypothesis: The sodium hydroxide used in this titration would balance out the acetic acid in vinegar. The phenolpthalein‚ a acid –base color indicator

Describe the role of the citric acid cycle as a central metabolic mechanism. Explain what happens to the cells’ abilities to oxidize acetyl CoA when intermediates of the cycle are drained off for amino acid biosynthesis. Glucose is a source of energy that is metabolized into glycolysis to pyruvate yielding ATP. To become more efficient‚ pyruvate must be oxidized into carbon dioxide and water. This combustion of carbon dioxide and water to generate ATP is called cellular respiration (Tymoczko‚

Application of lactic acid bacteria There are four major categories for the current uses and applications of LAB: food‚ cosmetic‚ pharmaceutical‚ and chemical applications. In food industry Recent years the interest increased in using LAB by using bacteriocin-like inhibitory substances (BLIS) because of their potential use as a natural antimicrobial agent to enhance the food safety of food products and increase the nutritional values of the food. Foods that fermented by LAB such as cheese‚ kimchi

1. Since the mid-1960 ’s‚ corporate liquidity has been declining. What reasons can you give for this trend? I think the reason for less liquidity since mid-1960’s is due to efficiency in management‚ use of cash flow‚ and the potential of maximizing earnings of a firm’s money. As our text puts it‚ it can be “traced to more efficient inventory management such as just-in-time inventory programs‚ point-of-sales terminals‚ more efficient cash management‚ electronic cash flow transfer systems‚ and

benzidine residue or protonation of the basic nitrogens on this station. Both of these methods rely on the repulsive electrostatic interactions between the positively charged axial component and the post-switching cationic nature of the benzidine station (Figure 5.4). Deuterated trifluoroacetic acid (d-TFA) was added in the solution which resulted in the protonation of the benzidine residue and shuttling of macrocycle in to the biphenol station of the Rotaxane. This was supported by NOESY 1H NMR

Calorimeter and of the Enthalpy of an Acid-Base Reaction Abstract The purpose of this lab was to first‚ determine the specific heat capacity of a homemade calorimeter‚ and second‚ to calculate the enthalpy of reaction for an acid-base reaction between 6M KOH and 6M HNO3. To determine the specific heat capacity of the calorimeter‚ two differing temperatures of water were measured and volume was measured and mixed within the calorimeter. The enthalpy of reaction for an acid-base reaction was found by
