The reaction of epoxide ring opening of caryophillene oxide has been done using zeolite H-Y, H-sodalit, and H-ZSM-5 as catalysts.The reactions were done in two types, there were in dioxane solvent at temperature of 110 oC and without solvent at temperature of 175 oC.The catalyst weight was 10 % from caryophillene oxide weight, and the ORG WHOLE ROO
Abstract Background In 2002 we investigated an outbreak comprising 231 patients in Norway, caused by Pseudomonas aeruginosa and linked to the use of contaminated mouth swabs called Dent-O-Sept.Here we describe the extent of contamination of the swabs, and identify critical points in the production process that made the contamination possible, in or
The strain state in 3D space is usually expressed by the conventional method of combining three linear and shear strains.Due to the obvious differences between the first two strains, it is necessary to uncover their properties when hat describing deformation, studying yield and failure, and developing test apparatus or equipment.The difficulties en
Activated carbons (ACs) were prepared by pyrolysis of seeds mango in presence of sodium and potassium hydroxide (chemical activities).Seeds mango from Colombian Mango cultives were impregnated with aqueous solutions of NaOH and KOH following a variant of the incipient wetness method.Different concentrations were used to produce impregnation ratios
