MOLECULAR MODELING 1. Objectives ● Predictthe shape of identified compounds; ● Construct molecular models of identified compounds; and ●Determine the molecular structure of identified compounds. 2. Theory Building models of molecules are useful for visualizing how atoms are connected in three-dimensional space called molecular geometry‚ which is best predicted by Valence-Shell Electron-Pair Repulsion (VSPER) theory. The following are the sets of rules summarizing thsi theory: ●

A molecular method for identifying Calicophoron infecting cattle in South Africa Lavinia Perumal School of Biological Sciences and Conservation‚ University of KwaZulu-Natal‚ Westville‚ Durban. Email:209512772@ukzn.ac.za Abstract Calicophoron species were collected from the ruminants of cattle from a Kokstad abattoir in South Africa. The second internal transcribed spacer (ITS-2) of the ribosomal DNA had been used as the genetic marker in this molecular study. In an attempt to identify as

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

Mitchell v. Lovington Good Samaritan Center‚ Inc.‚ 555 P.2d 696 (1976). Facts: The appellee was terminated from the Lovington Good Samaritan Center‚ Inc. on June 4‚ 1974. On June 12‚ 1974 Mrs. Mitchell applied for unemployment compensation benefits. She was initially disqualified from seven weeks of benefits by a deputy of the Unemployment Security Commission. Mrs. Mitchell then filed an appeal‚ and the Appeal Tribunal reversed the deputy’s decision. Mrs. Mitchell’s benefits were reinstated on

------------------------------------------------- Liquid–liquid extraction From Wikipedia‚ the free encyclopedia Liquid–liquid extraction also known as solvent extraction and partitioning‚ is a method to separate compounds based on their relative solubilities in two different immiscible liquids‚ usually water and an organic solvent. It is an extraction of a substance from one liquid into another liquid phase. Liquid–liquid extraction is a basic technique in chemical laboratories‚ where it is performed using a separatory funnel

Theories of Chemical Bonding 1. Which one of the statements concerning valence bond (VB) and molecular orbital (MO) bond theories is correct? a) MO theory predicts that electrons are localized between pairs of atoms. b) In VB theory‚ bonding electrons are delocalized over the molecule. c) MO theory accurately describes bonding in O2 and NO‚ VB theory does not. d) VB theory can describe molecular bonding in excited states. e) MO theory is used to accurately predict the colors of compounds

certain fluid. In this experiment two solutions are used. According to the definition of viscosity mobile liquids have a relatively low viscosity. Fluidity is the reciprocal of viscosity‚ given as equation 1: F=1/ η. Fluidity is advantageous because solutions of mixed solutions of nonassociating liquids are roughly additive. In this experiment binary solutions are used‚ so if each pure liquid has fluidities Fa and Fb‚ the fluidity of a mixture is given by: Equation1 (Halpern‚ 17-3).
