Imagining the modern American society without the internal combustion engine is like thinking of the United States without the Eastern Interconnection Power Grid. Modern Transportation is such a vital part of life in Western civilizations that there is no way to live without it. First world societies have glorified the use of fossil fuels and combustion engines which emit greenhouse gasses into the Earth’s atmosphere. In addition to the high amount of greenhouse gas emissions‚ humans are using up

State Heat Transfer laboratory were to study the rates of heat transfer for different materials of varying sizes‚ to develop an understanding of the concepts of forced and free convection and to determine the heat transfer coefficients for several rods. These objectives were met by heating several rods and allowing them to cool through free convection in air‚ free convection in water and forced convection in water- while monitoring their change in temperature over change in time. Seven heat transfer

DNA repair mechanism Response Elements - Enhancers that respond to metabolic factors - Ex. Heat-shock element (HSE)‚ glucocorticoid-response element (GRE)‚ metal-response element (MRE)‚ and cyclic-AMP-response element (CRE) Heat-shock Response Element - Elevated temperatures lead to the production of heat-shock transcription factors that activate the associated gene - Physiological signal: heat-shock - Consensus Sequence: CNNGAANNTCCNNG‚ where N stands for any nucleotide - Transcription

Properties of Gases General Chemistry 1 Lab 5 Abstract: The purpose of this experiment is to examine the properties of several gasses‚ which were the products of a reaction‚ and examine the way the gasses react under certain conditions. These conditions‚ such as introducing a flame to the gas as well as oxygen and CO2‚ caused other reactions to occur. Hypothesis: If the gasses are correctly synthesized then there will be a clear reaction with the introduction of the flame‚ O2‚ CO2‚ Air

Abstract In order to experiment with distinct components of a mixture‚ they must be first separated so they can be observed individually. This is accomplished in this lab by the technique called thin layer chromatography (TLC). TLC involves a stationary phase‚ which the TLC plates as well as a mobile phase‚ which could be one of two solvents used: ethanol-acetone for TLC. Dyes in a sample separate consequently because of their unique polarities. As a result‚ nonpolar substances travel further

Introduction Methyl Salicylate has been used for a long time for its pleasant odour and flavour. The objective of this experiment was to carry an organic synthesis; the preparation of salicylic acid from methyl salicylate. To do an organic synthesis‚ it is needed to chemically modify the molecules of another compound to end up with the desire compound. Methyl salicylate is the major constituent of wintergreen oil‚ which is why it was used in this experiment as the starting material. The new technique
