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...

In this study, the effect of usage additives at different initiator ratios as well fillers types and grain distributions on resin consumption compressive strength polyester matrix composites were investigated. Orthophthalic unsaturated (UP) was used a matrix. The (methyl ethyl ketone peroxide) ratio 1.0%, 1.5%, 2.0% accelerator (cobalt octoate) 1.0% by weight to start polymerization. Silica, ba...

Herein, the synthesis of pure and modified mesoporous nanocrystalline NiO is reported. The catalyst was with different wt % F-ions or K2O used to produce Methyl ethyl ketone (MEK) as a potential fuel/solvent. XRD analysis promoted catalysts confirmed formation Ni-metal covered by host oxide, compared NiO, especially for x F-ions. CO2-TPD results demonstrated existence basic sites over these var...

has been studied and the formation of acrolein as a product confirmed by gas chromatography-mass spectrometry. Oxi dation of 4-methylcyclophosphamide generates methyl vinyl ketone. This is interpreted to indicate that the acrolein and methyl vinyl ketone arise from oxidation of position 4 of the ring of cyclophosphamide. The Fenton oxidation of both cyclophosphamide and 4-methylcylophosphamide ...
