Becca Harris Writing 101 Position Paper Eliminating Genetically Modified Food at PLU What comes to mind when reading the words genetic modification or Bacillus thurigiensis (abbreviated Bt)? I envision laboratories and science experiments‚ when in reality these words are related to the food we eat every day. What most Americans do not know is the threat that genetically modified food presents to our communities. PLU should do everything in its power to ensure that its students and faculty

We only apply coating and do not undertake lining. Let us describe below the difference between coating and lining‚ as we understand: A coating is applied to a thickness of 10 microns to 1500 microns (0.01mm to 1.5mm). On the other hand lining can be between 3mm to 5mm or 3000 microns to 5000 microns. Lining is normally preferred where one needs to store various corrosive chemicals. Fluoropolymer lining is normally a sheet of Teflon/PFA/Tefzel/PVDF material either stuck to the shape of the vessel/item

another‚ a conjugated diene is formed. Conjugated dienes undergo a cycloaddition reaction with certain double bonds to afford cyclohexenes and related compounds. The reaction is named Diels-Alder. The Diels-Alder reaction is between 1‚3-butadiene and ethylene to produce cyclohexene + dienedienophile. The mechanism of the Diels-Alder reaction is classified as a [4+2] cycloaddition reaction‚ because one reactant (the diene)‚ contributes four carbon atoms and the other reactant (the dienophile) contributes

Cyclohexene Synthesis by Dehydration Reaction of Cyclohexanol Gjulia Vokrri 02-15-2013 Abstract Alkenes can be produced by heating and dehydrating an alcohol in the presence of a strong acid. The purpose of this experiment was to synthesize cyclohexene by dehydration of cyclohexanol and to detect the presence of a double bond in the alkene. The dehydration reaction using distillation was
