چکیده به منظور مطالعه مرز سنومانین-تورونین در زون های زمین ساختی ایران مرکزی و کپه داغ سه برش چینه شناسی در این نواحی انتخاب و از آنها نمونه برداری به عمل آمد. در ناحیه ایران مرکزی برش کلاه قاضی و در ناحیه کپه داغ برش های گردنه مزدوران و طاهرآباد ترک انتخاب گردیده اند. مطالعات زیست چینه نگاری بر روی فرامینیفرهای موجود نشان می دهد که برش های ناحیه کپه داغ در بر گیرنده سازندهای آیتامیر و آب در...
distal extension removable partial denture is a prosthesis with lack of distal dental support with a 13-fold difference in resiliency between the mucosa and the periodontal ligament, resulting in leverage during compression forces. it may be potentially destructive to the abutments and the surrounding tissues. the aim of this study was to assess the effect of implant location on stress distribu...
the aim of the present paper is the investigation of some problems which can be reduced to thegoursat problem for a third order equation. some results and theorems are given concerning the existence anduniqunce for solving the suggested problem.
TaN films with different N2 partial pressure were deposited on 304 stainless steel using the magnetron sputtering method. The effect of gas pressure on the mechanical property, morphology and phase structure of the films is investigated by X-ray diffraction (XRD), atomic force microscopy (AFM), microhardness testing, friction coefficient measurements, and wear mechanism study. The XRD results c...
comparison of partial- and full-mouth examination in periodontal assessment among untreated patients
objective: whole-mouth examination is generally considered as a gold standard for exact periodontal disease assessment. partial mouth examination also has sometimes been used for this purpose, but its efficacy has been questioned. with regard to symmetric destruction hypothesis of periodontal disease, the present study investigated the efficacy of partial- mouth examination as an alternative fo...
Objective microdeletions of Yq chromosome are the most frequent molecular genetics etiology for the male infertility which usually spans AZFa (azoo spermia factor a), AZFb and AZFc regions. Microdeletions are mostly seen in AZFc region and usually cover genes actively involved in spermatogenesis. Partial AZFc microdeletion may also happen with various spans namely gr/gr, b2/b3 and b1/b3. It is ...
