Speech I. The history of molecular gastronomy Molecular gastronomy is a new discipline about food science. This science investigates‚ explains and makes practical use of the physical and chemical transformations of ingredients that take place while cooking. But the truth is‚ using this science in cooking is not new. Pioneer Professors Evelyn G. Halliday and Isabel T. Noble: they said in their book “The main purpose of this book is to give an understanding of the chemical principles upon

The Effect of pH on the Rate of Osmosis Using a Glucose Solution Melissa Werderitch Biology 157 11/6/06 Introduction In a journal article written by Florian Lang‚ osmosis is essentially explained as the flow of water from one area to another that are separated by a selectively permeable membrane to equalize concentrations of particles in the two locations (Lang‚ 1997). Osmosis is able to maintain osmotic pressure and regulate a cell’s volume. In a hypotonic () or hypertonic () environment

mentions about the Freudian explanation that paranoia originates from the repression of same-sex desire. Sedgwick criticizes this conventional psychoanalysis‚ which inevitably pathologizes homosexuality as paranoia. As borrowing Hocquenghem’s reasoning‚ she argues that paranoia reflects not homosexuality‚ but rather the homophobic perspective on it. Nevertheless‚ Sedgwick condemns‚ many queer theorists duplicate the paranoid structure when they refute the homophobic explanation of paranoia. She infers

MOLECULAR ELECTRONICS INTRODUCTION Molecular electronics (sometimes called moletronics) is a branch of applied physics which aims at using molecules as passive (e.g. resistive wires) or active (e.g. transistors) electronic components. The concept of molecular electronics has aroused much excitement both in science fiction and among scientists due to the prospect of size reduction in electronics offered by such minute components. It is an enticing alternative to extend Moore’s Law beyond the

MOLECULAR FARMING INTRODUCTION Biotechnology in agriculture has two categories: 1. “Improvements” to existing livestock and crops‚ and 2. Development of entirely new uses for both animals and plants (biopharming). “Improvements"‚ include ‘input traits’ such as crops with extra resistance to insect attack‚ improved weed control‚ increase the plants tolerance to cold‚ drought and other environmental factor. Ex "Roundup ready" soya‚ "Starlite" corn‚ or "Frost-tolerant" tomatoes. WHY PLANTS

ABSTRACT A molecular diffusion experiment was conducted with the goal of determining the diffusion coefficient of acetone into air. For this experiment‚ acetone was placed in a capillary tube and was allowed to diffuse into non-diffusing air that was passed over the test tube at the temperature of 50oC.Thetemperature is kept constant and air stream is passed over the top of the tube to ensure that the partial pressure of the vapor is transferred from the surface of the liquid to be air stream bymolecular

Molecular Cell Biology – Spring 2013 Study Guide – Exam #3 Protein Folding & Post-translational Modifications -What are post-translational modifications? - are modifications that a proteins undergoes to achieve its mature state. Such as cutting‚ folding‚ splicing and other processes. -How do proteins achieve their final conformation? - A protein achieves its final conformation by spontaneously folding. All the information that the protein needs as to how to fold is already located

MEASURING pH Date of Lab: 02/09/13 Date Report submitted: 02/26/13 Purpose of the experiment By doing this experiment‚ we were trying to learn how to measure a pH with a pH meter to determine whether a solution is weakly‚ moderately or strongly acidic or basic; but also to compare the different data founded to see how the addition of certain liquid to a solution may affect the pH of the initial solution. Materials We used: * Tap water‚ distilled water‚ Soda and milk as the main
