let $pounds$ be the category of locally compact abelian groups and $a,cin pounds$. in this paper, we define component extensions of $a$ by $c$ and show that the set of all component extensions of $a$ by $c$ forms a subgroup of $ext(c,a)$ whenever $a$ is a connected group. we establish conditions under which the component extensions split and determine lca groups which are component projective. ...
این مطالعه در نظر دارد تا استحکام برشی 4 نوع سیستم چسبنده عاجی موجود در بازار را مقایسه کند. چهار نوع چسب عاجی شامل: 1-cleafil-se bond(kuraray) 2-etch&prime 3.03-excite single component(vivadent) 4-single bond(3m) است.

این تحقیق با استفاده آنالیز چند متغیره بر روی عکس های ذخیره شده بوسیله یک دوربین دیجیتال راه حلی را برای مسئله همپوشانی پیک ها که یکی از مسائل مهم در کروماتوگرافی لایه نازک است ارائه میدهد. ما برای اولین بار اندازه گیری همزمان چند گونه بر روی کاغذ کروماتوگرافی لایه نازک را با استفاده از آنالیز چند متغیره عکس مورد مطالعه قرار دادیم. سیستم عکسبرداری متشکل از یک کابینت، یک دوربین دیجیتال و یک بر...
BACKGROUND According to statistics of American Society of Plastic Surgeons, cosmetic rhinoplasty was the second most frequently performed cosmetic surgery. This study shares the experiences with component rhinoplasty. METHODS From 2004 to 2010, all patients underwent aesthetic nasal surgery were enrolled. The patients requiring only correction of septal deviation and those presenting with cl...

in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
در این رساله برهمکنش های بین مولکولی گوناگونی از قبیل پیوندهای هیدروژن، triel، tetrel و هالوژنی با استفاده از روش های محاسباتی کیفیت بالا در حد مجموعه پایه کامل بررسی شده اند. برهمکنش ها با نظریه اختلال تقارن سازگار با نظریه تابعیت چگالی، هارتری?فوک، مولر?پلاست مرتبه دوم و خوشه جفت شده تکی و دوتایی برای توصیف مونومرها مطالعه شده اند. بررسی ها از طریق کاربرد آنالیزهای اوربیتال پیوند طبیعی و ...
