This thesis is based on the emerging concept that pattern recognition molecules, originally characterized in the immune system, may be expressed and used by neurons to mediate also non-immune functions. In line with this concept, the major histocompatibility complex (MHC) class I and certain complements proteins have been implicated in synaptic plasticity in the developing visual system. In Pap...
Background: H2-EB1 molecule which is the homolog of Human HLA-DRB1 is proposed to be associated with allergic rhinitis (AR). Construction of H2-Eb1 knockout animal models provides a tool to elucidate the role of H2-EB1 and AR pathogenesis. Objective: To establish the H2-Eb1 knockout model and investigate the H2-EB1 functions in H2-Eb1 knockout mice as a model of AR. Methods: The Cre/Lox...
This research presents a nonlinear adaptive fuzzy control method as an analytical design and simple structure for the trajectory tracking problem in wheeled mobile robots with skew symmetrical property. For this robots, it is not easy to find solution due complicated error dynamics between controlled desired trajectories. deriving law of problem, filter link firstly adopted solvable dynamics, t...

Rhodium-alkene complexes of the pincer ligand ?3-C5H3N-2,6-(OPiPr2)2 (PONOP-iPr) have been prepared and structurally characterized: [Rh(PONOP-iPr)(?2-alkene)][BArF4] [alkene = cyclooctadiene (COD), norbornadiene (NBD), ethene; ArF 3,5-(CF3)2C6H3]. Only one these, alkene COD, undergoes a reaction with H2 (1 bar), to form [Rh(PONOP-iPr)(?2-COE)][BArF4] (COE cyclooctene), while others show no sign...
background: the objective of this study was to find an appropriate approach to asymptomatic malaria in elimination setting through a systematic review. methods: a broad search was conducted to find articles with the words ‘malaria’ in their titles and ‘asymptomatic’ or ‘submicroscopic’ in their texts, irrespective of the type of study conducted. the cochrane, medline/pubmed, and scopus databas...
mfi-type zeolite membranes (zsm-5) were prepared on α-alumina tubular supports and tested for separation of h2/co mixtures. the effect of pressure and temperature on h2 and co flows and selectivity was investigated. the best results in this work were obtained with a zsm-5 membrane prepared over a porous α-alumina tube seeded with zeolite nanocrystals synthesized with microwave technique. in thi...
در این پایان نامه به مسئله طراحی کنترلگر مقاوم مرتبه مشخص با جایگذاری قطب و قید عملکردی بهینه سازی نرم برای سیستم های با نامعینی پارامتری بیضوی پرداخته شده است. مسائل کنترل مقاوم با نامعینی بی ساختار به علت موجود بودن ابزارهای تحلیل و طراحی مورد نیاز و سادگی نسبی آنها توسعه بسیار بیشتری نسبت به مسائل با نامعینی ساختارمند و پارامتری داشته اند. با این وجود به علت محافظه کاری بالا در روش های مبتنی...
در کاربرد های عملی، اغلب برآوردن همزمان اهداف کنترلی متضاد مورد نظر است که به مسایل کنترل چندمنظوره می انجامد. گرچه برآوردن همه اهداف مطلوب می باشد، اما طراحی یک تک کنترلگر چندمنظوره محدود کننده است و کنترلگر طراحی شده اغلب محافظه کارانه یا از مرتبه بالا می باشد. در این رساله، به منظور کاهش محافظه کاری در طراحی کنترلگر و بهبود عملکرد، روش هایی برای کنترل چندمنظوره h2/h? مبتنی بر کلیدزنی و باسرپ...
