in the present work the effects of plasma nitridization on the passivation behavior of aisi 316l was investigated. to do this; nitriding treatments were carried out at 420°c for 1, 2, 4 and 16 hours. the phase composition and structure of the nitrided layer were studied by low angle x-ray diffraction and scanning electron microscopy. the hardness of samples also was evaluated by vickers microha...

diabetic ketoacidosis (dka) is characterized by excessive production of organic acids leading to a low blood ph. rarely, because of other complicating factors blood ph may be in the alkalemic range and the term diabetic ketoalkalosis has been coined to describe this condition. so far, less than 30 such cases have been reported in the literature. we report a 34-year-old woman who received methyl...

the experimental studies of methane conversion to higher hydrocarbons and methanol using a dielectric barrier discharge (dbd) reactor are presented in this article. the process is carried out at ambient atmospheric pressure and temperature. the dbd reactor is stimulated by an alternative voltage of 50 hz and amplitude of max.23kv. the examination of the effect of voltage and flow rates on metha...

in this paper, construction of triplet atmospheric plasma jet using argon, air, oxygen and nitrogen gases is reported. bactericidal effect of the plasma jet is also investigated. to that end, longitudinal geometric configuration for the electrodes was chosen because it would increase the jet length. electrical characteristics, jet length dependencies on the applied voltage and gas flow rate wer...

background: tumor lysis syndrome (tls) is a major metabolic complication in patients with malignancy after initiation of chemotherapy or spontaneously without treatment. the role of rasburicase (a recombinant urate-oxidase enzyme) in prevention and treatment of tls has been demonstrated in recent years. we aimed to investigate the efficacy of a single dose of rasburicase in reducing the risk of...

The purpose of this study was to determine changes in hematological and plasma indices of Common Carp Cyprinus carpio with regard to age, sex and hormonal treatment. Sixty fish were used to assess the age factor. Also, 20 fish including female and male were assigned to determine blood indices with regard to sex and hormonal treatment. The pituitary gland extract was used as hormone for males an...

      Wetability of biocompatible polymers can be improved by plasma surface modification. The purpose of this study was to surface modify an experimental poly (dimethylsiloxane) rubber (PDMS) material in order to improve its wetability and biocompatibility. Surface properties of the PDMS were characterized using contact angles measurement for wetability analysis. Samples of experimental silico...
