There are many impacts that could affect the academic achievement .one of them is reducing class size. Based on the work of a group of researchers headed by Gene Glass and Mary Lee Smith‚ 15 students was chosen to be the number of students in small class size for the major benefits to be obtained (Glass‚ et 1978).It is suggested that reducing class size by five student is expensive but it is not found to be as costly as lengthening the school day or using computer assisted instructor. It can have

Size Exclusion Chromatography Size Exclusion Chromatography (SEC) is the separation technique based on the molecular size of the components. Size exclusion chromatography is a kind of method to separate different size of molecules that put in solution. It was first discovered by two scientists who named Grant Henry Lathe and Colin R Ruthven. Both of them received the John Scott Award for this fabulous invention. There are various applications for Size exclusion chromatography such as biochemical

Sample size The process of determining the proper sample size was established through a series of calculations and after obtaining all the possible sample sizes‚ the largest one was taken into consideration to collect the closest number to a representative sample of the population. The following two equations where used: Equation 1: N=z2 *(p.q) E2 N= sample size Z=level of confidence interval at 95% so z=1.96 P=estimated percent of population E=acceptable sample error expressed

Daniel Osherow ENGR 1301 5 December 2012 Copper Wire Sizes (EE) The diameter of a copper wire is measured by using a system called the American Wire Gauge also known as AWG. This system has predominantly been used in the United States and Canada since 1857. Using this measurement the cross-sectional area of a gauge is able to be found. We then use this area to determine the wires current carrying capacity. The gauge numbers for wire and diameter values work inversely‚ as when one increases the
