The rapid conversion of conventional powertrain technologies to climate-neutral new energy vehicles requires the ramping electrification. popularity fuel cell electric with improved economy has raised great attention for many years. Their use green hydrogen is proposed be a promising clean way fill gap and maintain zero-emission ecosystem. complex architecture influenced by multiphysics interac...

A procedure has been developed for the automated measurement of conjugated bilirubin in serum with a centrifugal analyzer. The conjugated bilirubin is measured by a fixed time kinetic method which monitors the reaction between conjugated bilirubin and diazotized sulfanilic acid at 550 nm. Results are calculated based on a comparison of the reagent blank-corrected absorbance changes between 15 s...

introduction: implantation of transferred embryos in the uterus after ivf_icsi cyclesis an important process that less information about it is available. zona hatching method is a suggested approach for this goal. the aim of this research is about performance of zona hatching by laser. methods: in this study 32 patients that enrolled had ivf/icsi cycles depend on inclusion criteria of study tha...

background: endometrial remodeling occurs during each menstrual cycle in women. reports have shown that, in a variety of cell types, processes such as proliferation, signaling complex formation and extra cellular matrix remodeling require a cytoplasmic tyrosine kinase, focal adhesion kinase (fak). the present study has focused on the expression pattern of fak in human endometrium during the men...

objective: to evaluate effects ofg-csf on a cancelled art cycle due to thin endometrium. materials and methods: in a nonrandomized clinical trial from january 2011 to january 2013 in two tertiary university based hospitals fifteen patients undergoing embryo transfer and with the history of cycle cancellation due to thin endometrium were studied. intrauterine infusion of g-csf was done on the da...

in this paper the effects of non-linearity of suspension on dynamic behavior of a railway wheelset has been studied. this wheelset has four degrees of freedom that with two constraints it has reduced to two degrees of freedom. vermeulen-johnson theory has been used to calculate contact forces between wheel and rail. in this study the creep coefficients have considered constant. any linearizatio...

background: the main object of this experimental work was to practise laboratory production both adult and the larval stage of hymenolepis diminuta with conventional modification to make further studies easier. materials & method: adults h. diminuta were collected from urban rats in tehran, iran. the beetles became infected using blended gravid segments with flour as bait. cysticercoids have be...

percentages and yields of fat, crude protein (cp), true protein (tp) and non-protein nitrogen (npn) wereassessed in milk of four groups of holstein cows, at early, mid and late lactation (days in milk 20-70, 71-110, 111-150 and 151-210), on a diet rich in concentrates during a hot summer. four milk samples were taken from individual cows at 10-day intervals. milk fat percentages were close to b...

the aim of this study was to evaluate the defense cells changes of cervical mucous during follicular and luteal phases of estrus cycle in river buffalo. reproductive organs of the adult and apparently healthy female buffaloes were collected from the slaughterhouse. by visual investigation of both the ovaries for presence of corpus luteum and growing follicles, the luteal and follicular phase of...
