Speaking Engagements—The Rubber Chicken Circuit One of the important parts of my job was public speaking. Having been a college teacher and having taught a lecture class of over 350 students in General Botany and well over 100 in Ecology‚ I was comfortable speaking before audiences. The talks I gave almost always fell into three categories: explaining our departments programs‚ promoting our departments programs‚ and presentations on current environmental issues. Generally‚ I enjoyed these speaking

Introduction - Electric circuit theory is one of the fundamental theories upon which all branches of electrical engineering are built. - Many branches of electrical engineering‚ such as power‚ electric machines‚ control‚ electronics‚ communications‚ and instrumentation‚ are based on electric circuit theory. - In electrical engineering‚ we are often interested in transferring energy from one point to another. - To do this requires an interconnection of electrical devices. - Such interconnection is

Introduction The aims of the lab session was to familiarize with the principles‚ operation and application of a light spectrophotometer. This report discusses an experiment to study the relationship of absorbance and concentration‚ the interaction of electromagnetic radiant energy(ERE) and matter which is an important aspect of the Beer-Lambert ’s Law. This law states that the absorption of a compound is directly proportional to the concentration of that particular compound. This is because (a &

Premium Chemistry Ethanol Acetic acid
1-Aminocyclopropane-1-Carboxylic acid Synthase (ACS) catalyzes the conversion of AdoMet to 1-aminocyclopropane-1-carboxylic acid (ACC)5‚ which is the rate-limiting step in ethylene biosynthesis. ACC is then converted to ethylene by ACC oxidase (ACO)‚ a member of the oxygenase/oxidase superfamily of enzymes6.The ACS plays a central role to regulate ethylene production through changes in ACS gene expression levels and the stability/activity of the enzyme. ACS proteins can be divided into 3 groups (type-1‚ 2 & 3) based on their C-terminal

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise
