Four nonvolatile nerve agent surrogates, 4-nitrophenyl ethyl dimethylphosphoramidate (NEDPA, a tabun surrogate), 4-nitrophenyl ethyl methylphosphonate (NEMP, a VX surrogate), and two sarin surrogates, phthalimidyl isopropyl methylphosphonate (PIMP) and 4-nitrophenyl isopropyl methylphosphonate (NIMP), were synthesized and tested as acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) i...
در این تحقیق، یک حسگر گازی مقاومت شیمیایی مبتنی بر گرافن اکسید احیا شده برای آشکارسازی گزینشپذیر دیمتیلمتیل فسفونات (DMMP) به عنوان شبهعامل اعصاب توسعه داده شده است. احیای گرافن اکسید توسط عوامل احیا کننده‌های مختلفی مانند آسکوربیک اسید، گلوکز، هیدرازین هیدرات و پارافنیلن دیآمین انجام گرفت. گرافن اکسیدهای احیا شده که به خوبی در آب مقطر پراکنده شده بودند؛ با روش قطره‌چکانی روی سطح الکتروده...
Acknowledgments At the start of a Ph.D. project, you never know where it will take you. Though the research plan for my project contained several paragraphs on the planned research for the first two years, the plan for the last two years consisted of only a couple of lines. Even this concise plan turned out to be too detailed, since some research directions turned out to be less promising than ...
piroxicam is a non-steroidal anti-inflammatory agent which has an extensive use in rheumatic disorders. since its skin penetration is still a subject for research, the aim of this study was to evaluate the effect of dimethyl sulfoxide on percutaneous penetration of piroxicam gel formulation through skin. in this study, as a model, two types of 0.5% piroxicam new gels, so called red and green ge...
The syntheses of four D-myo-inositol 1,4,5-trisphosphate (InsP(3)) derivatives, incorporating phosphate bioisosteres at the 5-position, are reported. The methyl phosphate ester and sulfate derivatives retain InsP(3) receptor (InsP(3)R) agonist activity; the compounds that possess a methylphosphonate or a carboxymethyl moiety are InsP(3)R antagonists.
Recently, Mandal and Gong [23] refined and analyzed the recursive method by Lempel and Mykkeltveit et al. for generating de Bruijn sequences, where the recursive feedback function is the sum of a feedback function with k-th order composition and a sum of (k + 1) product-of-sum terms. In this paper we first determine the linear complexity of a composited de Bruijn sequence. We then conduct a pro...
