t cells have been identified as key players in the pathogenesis of type 1 diabetes. however, the exact role of t-cell subpopulations in this pathway is presently unknown. the purpose of this study was to assess the expression pattern of two lineage-specifying transcription factors gata - 3 and t - bet , which are important in t helper type 1 (th1) and th2 cell development , respectively. gene e...

determination of 1, 1-dimethylhydrazine (dmh) in air is carried out by spectrophotometry, gc or hplc analysis, but in this study dmh was analyzed by a gas sensor based on nanostructure conducting polyaniline. determination of dmh has been done very simplely and quickly in recent work. electrically conductive fibers have been prepared by polymerization of aniline on surfaces of commercial polyme...

تفکیک دو بعد مطلق و نسبی دین از یکدیگر و بازشناسی بعد مطلق آن، یکی از مهم‏ترین رسالتهای دین‏شناسان امروز به شمار می‏آید. بعد مطلق یا ضروری، یعنی سلبز، سلبابز یا سگوهرز دین، همان پیام فی‏نفسه دین است که خدا می‏خواهد آدمیان بدان برسند و آن را تحقق بخشند; و بعد نسبی یا امکانی آن، یعنی سقشرز، سحجابز یا سصدفز دین، مجموعه عناصری است که فقط به پوشش انسانی پیام تعلق دارد و طبعا سمنطقه‏ایز است; یعنی آب ...

We study geometric limits of convex-cocompact cyclic subgroups the rank 1 groups SO_0(1, k+1) and SU(1, k+1). construct examples sequences such G that converge algebraically whose limit strictly contains algebraic limit, thus generalizing example first described by Jorgensen for SO_0(1,3). also give necessary sufficient conditions a subgroup to arise as sequence subgroups. then discuss generali...
