strategy. The first part of Porter’s Five-Force model is rivalry. According to Porter‚ rivalry focuses on two main factors which are a high concentration ratio and a low concentration ratio. A high concentration ratio indicates that a high concentration of market share is held by the largest firms which the industry is concentrated. A low concentration ratio indicates that the industry is characterized by many rivals‚ none of which has a significant market share (Porter‚ 2010). Porter offers

Article: Information technology: a growth navigator for small scale industries in India Small scale industries (SSI) have a significant role in the Indian economy in view of its contribution to production‚ employment‚ and export. However‚ since 1991 small scale industries in India find themselves in an intensely competitive environment due to globalization‚ domestic economic liberalization‚ and dilution of sector specific protective measures. The formation of World Trade Organization in 1995 also

equal or no solute forms an isotonic solution. Throughout this lab‚ data was collected and compiled to analyze these effects across selectively permeable membranes. The results indicated that the water molecules indeed move from high concentration to low concentration‚ while solutes do the same if the membrane is permeable to them. This was evident through our experiments in which membrane permeability was tested in living Elodea plant cell‚ which was placed in 3 different solutions‚ from distilled

Abstract Through three different experiments we were to find the quality of NaCl as a deicer. These experiments included testing the freezing point depression of NaCl in solution at two different concentrations‚ testing for the H of an aqueous NaCl solution‚ and combining NaCl with MgCl2 in an aqueous solution to test for freezing point depression. Through these various experiments we found NaCl to be the best deicer for our region due to its proficient freezing point depression and its cost

supported the hypothesis that if Daphnia are placed in differently concentrated solutions of barium and calcium chloride‚ then the highest concentration of calcium chloride would affect them the most because of the production of hydrochloric acid and calcium oxide from the mixing of water and calcium chloride‚ two very dangerous acids‚ with the highest concentration having the biggest chemical reaction. Within five minutes of putting the Daphnia into the 10 (ppt) solution of calcium chloride‚ one or

of light reaching the solution is needed. Each solution with a different solute has its own characteristic absorption property or spectrum. Spectrophotometer can also be used to find out the concentration of compounds in solution because the amount of light absorbed is directly proportional to the concentration of absorbing compounds in that sample. When a solution like bromophenol blue absorbs certain wavelengths of light in the visible spectrum and transmits or reflects others‚ it appears coloured

region of higher concentration to a region of lower concentration. This happens because of random molecular motion. Molecules move around randomly until there is an even mixture throughout cell and mixture. The overall effect is that molecules move down a concentration gradient from a region of high concentration to a region of low concentration which is passive transport. Osmosis is the movement of molecules down a concentration gradient and at the same time
