background: in this study, two-dimensional gel electrophoresis (2-de) method was applied to determine and compare the protein spots expressed in the two field isolates of leishmania major and recovered from the patients who were clinically sensitive and resistant to glucantime® treatment. methods: leishmania parasites were isolated from the cutaneous lesions of two cl infected patients in shira...
Introduction: The purpose of this study was to compare dimensional changes of two types of auto polymerizing acrylic resin patterns (APARPs) in three different storing environments. Methods: 60 acrylic post and core patterns were made of two types of Duralay acrylic resins (Aria dent, Iran and Reliance, Dental Mfg. Co, USA) using a canine model. Then coronal, apical diameter and coronoapical le...

introduction: the purpose of this study was to compare the setting time and post-setting solubility, flow, film thickness and dimensional changes of ah26 root canal sealer with ah26-antibiotic combination. materials and methods: this study was performed according to british standard bs 6876 (2001) which tests the physicochemical properties of endodontic sealers. three samples of each of tested ...
در این پایان نامه سعی شده است برنامه ای جهت تحلیل سازه های دوبعدی تحت تاثیر بارگذاریهای مختلف ارائه گردد که قابل اجرا بر روی windows های 95 و 98 و یا بالاتر خواهد بود. در این برنامه که به نام aprodis، بر گرفته از حروف اول کلمات analysis program for two dimensional structure نامگذاری شده است ، امکانات متنوعی جهت استفاده کاربر تعبیه شده است . از جمله این موارد می توان به قابلیت ارائه شش نوع بارگذ...
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
The digital image contains efficient and useful information which enables measurement and data acquisition. One of the methods that facilitate measuring and interpreting objects, using the image solely, is close-range photogrammetry. Among the various fields of science, whenever a precise measurement is required, this approach can be applied. One of these fields is Medical Sciences that due to ...
In this paper, the nonlinear bending analysis for annular circular nano plates is conducted based on the modified coupled stress and three-dimensional elasticity theories. For this purpose, the equilibrium equations, considering nonlinear strain terms, are calculated using the least energy potential method and solved by the numerical semi-analytical polynomial method. According to the previous ...
