Background: Recurrent abortion is defined as three or more consecutive pregnancy losses. We aimed to determine the relationship between male sperm parameters and hypo-osmotic swelling score and recurrent abortion. We also studied whether washing of spermatozoa and intrauterine insemination in patients with recurrent miscarriage and low score hypo-osmotic swelling test in male partners could imp...
cross-linked polymeric organogels have attracted much attention in recent years. most synthesized organogels are based on low molecular weight or denderitic materials. the study focuses on the preparation of an alcohol absorbent organogel based on 2-acrylamido-2-methylpropane sulphonic acid (amps) through cross-linking polymerization. polyethylene glycol diacrylate-400 and ammonium persulphate ...
Austenitic stainless steel SS304 grade was welded with active Tungsten Inert Gas (TIG) welding process by applying a flux paste made of SiO2 powder and acetone. SiO2 flux application improves the weld bead depth with a simultaneous reduction in weld bead width. The improvement in penetration results from arc constriction and reversal of Marangoni convection. Experimental studies revealed that t...
زمینه و هدف: دیالیز ناکافی یکی از عوامل اصلی مرگ و میر بیماران دیالیزی است و در پیش آگهی این بیماران کاملاً مؤثر است. پژوهش حاضر با هدف تعیین کفایت دیالیز و ارتباط آن با نوع صافی در بیماران مراجعه کننده به بیمارستان 22 بهمن گناباد انجام شد. روش تحقیق: این مطالعه مقطعی، بر روی کلیه بیماران تحت درمان با همودیالیز بیمارستان 22 بهمن گناباد که مایل به شرکت در این مطالعه بودند، انجام شد. کلیه بیمارا...
In the present study, a typical flux containing 90wt% NaCl-KCl, 8wt% Na2SiF6 and 2wt% CaF2 was used to remove the inclusions from the melts of A380 and A319 aluminum alloy scraps. The effect of flux amount on refining efficiency was investigated using tensile test, reduced pressure test (RPT), metallography and SEM. The effect of flux on the 6063 wrought aluminum melts was also studied. On the ...
