BUSINESS ECONOMICS Assignment 1 Case study: Mintel batteries report a) What happened to sales of batteries in the period 2004-8? Provide a quantitative estimate. How do you explain the fact that over that period the amount of batteries sold increased whereas the value of sales declined? From figure 20 we can see that the volume of sold batteries from 2004 (584 million batteries) to 2008 (611 million batteries)

Artocarpus integrifolia Linn. f. (Jack fruit)‚ and Eugenia jambolana Lam. (Black plum) on silk yarn. The natural mordant used in the research work is Aluminium Potassium Sulphate (AlK (SO4)2) for better fixation of the dyes. The dyes are extracted by alkaline method and the extraction time is optimized from the optical density values. The pre-mordanting method is used for mordanting the yarn. Shades of different colours‚ ranging from yellow to brown are obtained from the dyes on silk yarn. Fastness grades

Turning biodegradable waste such as food scraps and yard trimmings into compost or recycling them through your local yard waste collection facility‚ eliminates a large portion of any household or business’s waste stream. However‚ the bulk of waste does not biodegrade quickly or ever. By thinking ahead‚ you can reduce your waste generation and reuse packaging rather than throwing it away. Consider Packaging When buying food or consumer goods‚ the U.S. Environmental Protection Agency recommends you

IN FLY ASH BASED GEOPOLYMER. By: NOR HANIM BINTI KHIYON Supervisor’s Name : DR ANDRI KUSBIANTORO 1.0 INTRODUCTION Geopolymer paste is created by combining fly ash‚ which contains alumino-silicate source‚ with a strong alkaline solution. Geopolymer concrete has significant advantages over standard concretes such as resistance to corrosion and fire‚ high compressive and tensile strengths and also less shrinkage. The development of geopolymer concrete is an important step
