Dry thin collodion membranes have been prepared which are permeable to water, ammonia, weak acids of low molecular weight, HCl gas, O(2), CO(2), and H(2)S, but are impermeable to strong electrolytes and substances of high molecular weight. The permeability to gases does not depend on the density, so that the gases do not pass through pores in the membrane.

objective: although in vitro studies have shown that high concentrations of glucose can induce dysmorphogenesis of the embryonic kidney, the possible adverse effects of exposure to intrauterine hyperglycemia on kidney development, especially in regard to nephrogenesis, has not been evaluated. the aim of this study is to investigate the effects of maternal diabetes on glomeruli structures of the...
The conformation of the N-H and C=O bonds in the title compound, C(8)H(7)Cl(2)NO(3)S, is trans. The benzene ring and the SO(2)-NH-CO-C group form a dihedral angle of 79.75 (8)°. Mol-ecules are connected via N-H⋯O hydrogen bonds to form linear supra-molecular chains.
background: studies have shown that zinc and selenium deficiency is common in nonalcoholic fatty liver disease (nafld). however, the effects of zinc and selenium co-supplementation before and/or after disease progression on nafld are not clear enough. the aim of this study was to compare the effects of zinc and selenium co-supplementation before and/or after disease progression on nafld prognos...
To determine how a substitutionally inert metal can play a catalytic role in the metalloenzyme nitrile hydratase (NHase), a reactive five-coordinate Co(III) thiolate complex ([Co(III)(S(2)(Me2)N(3)(Pr,Pr))](PF(6)) (1)) that resembles the active site of cobalt containing nitrile hydratase (Co NHase) was prepared. This was screened for reactivity, by using low-temperature electronic absorption sp...
Vaccine refusal occurs for a variety of reasons. In this article we examine vaccine refusals that are made on conscientious grounds; that is, for religious, moral, or philosophical reasons. We focus on two questions: first, whether people should be entitled to conscientiously object to vaccination against contagious diseases (either for themselves or for their children); second, if so, to what ...
Background and Aim: Due to the importance of scientific relations between university and industry, it is so important to identify the factors that affect these relations. So,the aim of this study is to investigate the effect of spatial proximity on university- industry collaboration. The collaboration indicator which is used here is University- Industry Co-publications. Methods: The research is...
در این مقاله می خواهیم با روشهای پیدا کردن تانسور پواسون سازگاربا تانسورکانونیک روی دوگان جبر لی so*(4) آشنا شویم. ساختارهای پواسون درجه دوم روی so*(4) و e*(3) طبقه بندی شده اند، که هر کدام دارای برگ بندی با برگهای سیمپلیکتیک به عنوان تانسورهای لی پواسون کانونیکال هستند. متغیرهای تفکیک پذیر برای برخی ازسیستم های دوانتگرالی متناظرساخته شده اند.
