North American Free Trade Agreement (NAFTA) and the Association of Southeast Asian Nations (ASEAN) are the most famous trade blocs. Additionally‚ in the Northeast Asia‚ China‚ Japan and Korea are undertaking preliminary research into the formation of a FTA. The formation of those FTA can be viewed as a way of gaining further benefits from free trade and investment during the long-term process of forming a global common market. Yet it has changed the situation of global economy to a certain degree. This

of Freud’s most basic theories‚ such as his theories of identification‚ the role of transference‚ and the way in which the symptom is a formation of the unconscious.” “Freud’s case histories illustrate very clearly some of Freud’s most basic theories‚ such as his theories of identification‚ the role of transference‚ and the way in which the symptom is a formation of the unconscious.” I have chosen the Ratman as the case history I will use to illustrate Freud’s theories. The Rat Man exposes many

percentage purity of solid C was found to be 6.01%. The melting point range of purified solid C was 117.0 – 119.0C while the boiling point of liquid C was found to be 117C. The identity of solid C and liquid C was found to be benzoic acid and butyl acetate respectively. INTRODUCTION The isolation of individual or groups of compounds can be accomplished

Explore the role of digital media‚ particularly the World Wide Web‚ in the formation of online communities and the new forms of social/cultural identities in virtual space. What implications do new forms of interactions online have on our understanding of ‘community’ and ‘democracy’? Digital media is responsible for the formation of online communities and creating a society and culture that merges societies and divisions‚ and thus this form of medium has become more real to humans than reality

Compare and contrast the Marxist and Weberian theories of social class. Why do you think Marx emphasises relations of production in the formation of classes whilst Weber suggests the market and consumption are the important factors? All human societies have been class based in some way‚ shape or form and‚ interpreting this in the most basic way‚ it can be said that in every known human society there has been a fundamental division between two broad social groups‚ the buorgeoisie that own and control

Experiment 19: Fischer Esterification‚ Conclusion The objective in this experiment was to efficiently perform an Fischer esterification of 1-butanol and acetic acid to form water and n-butyl acetate‚ and to confirm the esterification using IR spectroscopy analysis. It was found that 0.734 grams of n-butyl acetate was formed with a percent yield of 61%. The product was confirmed using IR spectroscopy and boiling point confirmation. The reaction mechanism for this specific reaction was as follows:

distillation techniques: simple and fractional. Simple distillation was done to separate ethyl acetate—which has a usual boiling point of 77º—from a less volatile component‚ while fractional distillation was done to distinguish an ethyl acetate/n-butyl acetate mixture‚ which has boiling points of 77º and 125 º‚ respectively. Results and Discussion As previously stated the standard boiling point for ethyl acetate is 77º. The data obtained resulted with the experimental boiling point being approximately

SYNTHETIC EXPLOITATION OF ENZYMES: BIOCATALYSIS IN ORGANIC SOLVENTS: FUNDAMENTALS ENZYMES IN ORGANIC SYNTHESIS 1. Enzymes catalyze a broad spectrum of reactions with high turnover numbers. Rate enhancements approach 1012 fold. 2. Enzymes may accept a wide range of substrates. 3. Enzymes are highly regio and stereoselective. 4. Enzyme reactions take place under mild conditions; this minimizes problems of isomerization and racemization. 5. Enzymatic processes are less hazardous and polluting
