November 25‚ 2012 The Effect of the pGLO Plasmid on Genetic Transformation of E.coli by Heat Shock Introduction Genetic transformation is the genetic alteration of a cell resulting from the direct uptake‚ incorporation and expression of exogenous genetic material l(exogenous DNA) from its surroundings and taken up through the cell membranes. This was first demonstrated in 1928 by Bacteriologist Frederick Griffith (Lederberg 2000).A plasmid is a small circular piece of DNA that contains important

Question: Which heats up faster: sand or water? Hypothesis: Sand heats up faster than water because it has a lower specific heat. Water has a specific heat‚ which requires one calorie of energy to raise the temperature of one gram of water by one degree Celsius. Sand has a lower specific heat. It takes .19 calories per gram to raise the temperature of the sand by 1 degree Celsius. Sand requires fewer calories to raise its temperature one degree Celsius and that’s why it heats up faster than water

Influence of Heat Treatment on Hardness and Corrosion Resistance of Commercial Aluminium Mayeedul Islam 1‚*‚ S. M. Najmul Hoque2‚ M. Abdullah Al Mahmood2‚ A. A. Shisir 2 ABSTRACT Aluminium and their alloys are widely used as construction materials from house hold appliances to air-craft parts. The commercially pure aluminium has merely low corrosion resistance and hardness compare to aluminium alloy. In this study an attempt has been made to study the influence of heat treatment on the properties

Heat release rate of a subway car on fire in a shrink-scale model Abstract: Heat release rate in a shrink-scale model of a subway car on fire is measured for various aspects of an ignition source and simulated materials differing in material by using shrink scale model. The time is required to reach the value‚ although the maximum Heat Release Rate value is independent of the position of the ignition source. The best method for determining the heat release rate is the maximum Heat Release Rate
