in this study, the effects of various concentrations of nacl and kcl and partial replacement of nacl withkcl on the growth characteristics of l. monocytogenes were evaluated. it was found that l. monocytogenescan grow in the presence of 1-9% nacl and 1-11% kcl. the higher the concentration of salt used, the longerthe lag phase induced. in addition, it was observed that l. monocytogenes tolerate...

mgcl2/c2h5oh adducts with constant relative ratio of 1/3 were prepared and kept at 120oc for different lengths of times of 5, 10, 20, 30, 50, 90,120 and 220 h. then the samples were quenched and analyzed by xrd and bet. no meaningful changes were observed in the specific surface area of the samples, while xrd spectra showed 3 peaks at 2θ<15o for samples kept at 120oc for 5 h. these 3 peaks were...

Some fundamental data related to the solvent proposed for a new technical electrolytic process for magnesium production based on MgO as the raw material are presented. Liquidus data are obtained for MgCl2-rich melts in the MgCl2-NdOCl system. The solubility of MgO and NdOCl in pure liquid NdCl3, MgO in NdCl3-MgCl2 and in MgCl2-NdCl3-NaCl liquid mixtures, and NdOCl in CaCl2 and Cs2MgCl4 have als...

The ability of different metal ions to promote transformation of Pseudomonas aeruginosa by deoxyribonucleic acid of the plasmid RP1 was examined. CaCl2, MgCl2, and MnCl2 were found to promote such transformation, although at different frequencies and with the optimum response at different concentrations. Only MgCl2 promoted transfection of P. aeruginosa by the linear deoxyribonucleic acid of ph...

BACKGROUND Magnesium, ropivacaine, gentamicin, and rocuronium block neuromuscular (NM) transmission by different mechanisms. Therefore, concurrent administration of these agents may induce prolonged muscle paralysis via synergistic interaction. This study investigated the efficacy and safety of NM block caused by the administration of high concentrations of magnesium in combination with ropivac...

heterogeneous ziegler-natta and homogeneous metallocene catalysts exhibit greatly different active sitenature in olefin polymerization. in our previous study, it was reported that mgcl2-supported titanocenecatalysts can generate both ziegler-natta-type and metallocene-type active sites according to the type of activators.the dual active site nature of the supported titanocene catalysts was furt...

The applications of clathrate hydrates on carbon dioxide capture and desalination is an attractive growing subject within the hydrate community. While many promoters exists to overcome numerous issues hydrate-based technologies (mostly how mild operating conditions improve kinetics), there a need find guest that could be recovered easily. That why cyclopentane (CP), organic molecule not miscibl...

Acanthamoebe profilin has a native molecular weight of 11,700 as measured by sedimentation equilibrium ultracentrifugation and an extinction coefficient at 280 nm of 1.4 X 10(4) M-1cm-1. Rabbit antibodies against Acanthamoeba profilin react only with the 11,700 Mr polypeptide among all other ameba polypeptides separated by electrophoresis. These antibodies react with a 11,700 Mr polypeptide in ...
