introduced a new concept called Integrated Marketing Communication (IMC). This concept has generated a great interest among academics and practioners‚ although research regarding its frequency and implementation is limited. IMC have been defined in numerous ways‚ all stressing the fact that IMC’s Task is to combine all corporate media and messages to project clarity‚ consistency‚ and maximum communication impact in its surroundings. Percy (1997) defines integrated marketing communications as “the

The purpose of this experiment is to synthesize isopentyl ester by an esterification reaction between a carboxylic acid and an ester. Carboxylic esters‚ like isopentyl acetate‚ are normally used to create artificial flavors. In the preparation of isopentyl acetate‚ esterification of acetic acid and isopentyl alcohol occurs. Esterification is an equilibrium shift to the product side using an excess of one of the starting components. In this experiment‚ the excess reagent is acetic acid because it

Synthesis of Information In summary‚ the articles researched were divided into four main categories. The categories all focused on something different. The categories were; the perception kids have on food‚ communities raising healthy kids‚ nutritional awareness and the school context. The first two articles had the common theme of how children view food and to find what children thought and felt about healthy food. The third article was aimed towards parents. The theme of this article was how
