the potential energy hyper surfaces (fes) of the unimolecular rearrangements of a) nitromethane itei totrans acknitromethane b) nitrometharie (/) to methyl nitrite (3) and c) naromethane decomposition tomethyl and nitrogen dioxide were searched using the ab !nth° mp2 method. split valence 6-310(d.p) basisset was used for geometry optimizations, frequency and 1rc computations along each reaction...

normal 0 false false false en-us x-none ar-sa backgrounds : lumbar disc herniation (ldh) is the most common surgical intervention of spine surgery. during few days of the operation, most patients experience worrying low back pain ( lbp) and radicular leg pain (rlp). applying liquid form of bupivacaine in the vicinity of surgical field could be effective on pain relief only for few hours after o...

photocatalytic decolorization of methyl orange (mo) solution has been studied using phosphotungstic acid (hpa) as photocatalyst. the decolorization reaction of mo solution is photocatalysis. the paper reveals that the optimal loading of photocatalyst for decolorization of mo solution (10 mg/l) is 0.6 g/l. the results show that the photocatalytic decolorization reaction of mo with hpa in a homog...

oxidation of methyl orange (mo) solution in potassium peroxydisulfate (kps) homogeneous reaction system without uv irradiation was investigated. the result shows that decolorization of mo increases as the dosage of k2s2o8 increases. the kinetic results demonstrate that the decolorization reaction is a pseudo first-order reaction when the concentration of mo is below 10 mg/l and langmuir–hinshew...

a valuable composition of mentha piperita l. essential oil is menthol that is widely used fordifferent industries. the plants were treated with different concentrations of methyl jasmonate (meja) and after 24 h were evaluated for total soluble proteins, chlorophylls (a, b, and total), malondialdehyde, carbohydrates and antioxidant enzymes (superoxide dismutase and guaiacol peroxidase). variance...
