The inflammatory response adjacent to implants has not been well-investigated and may influence peri-implant tissue levels. The purpose of this study was to assess, histomorphometrically, (1) the timing of abutment connection and (2) the influence of a microgap. Three implant designs were placed in the mandibles of dogs. Two-piece implants were placed at the alveolar crest and abutments connect...
Various techniques for scleral fixation of IOL in cases of poor capsular support have been described in past. Sutured scleral fixation of IOLs has been attempted for single piece and toric IOLs also. But this predisposes to various suture releated complications. Sutureless fixation of three piece IOLs with or without glue has gained popularity worldwide. However, odd power lenses and high astig...
Rovers will continue to play an important role in planetary exploration. Plans include the use of the rocker-bogie rover configuration. Here, models of the mechanics of this configuration are presented. Methods for solving the inverse kinematics of the system and quasi-static force analysis are described. Also described is a simulation based on the models of the rover’s performance. Experimenta...

پوششهای tbc یکی از جدیدترین و پیشرفته ترین پوششهایی است که امروزه در توربینهای گازی نیروگاهها و توربینهای هواپیماها استفاده می شود. این پوششها با ایجاد اختلاف دما در حدود 100 تا 150 درجه سانتیگراد، باعث افزایش عمر سوپرآلیاژهای قطعات داغ و نیز باعث صرفه جویی چشمگیری در مصرف سوخت نیروگاهها و هواپیماها می گردد. در این تحقیق، بحث و بررسی در مورد علل تخریب پوششهای tbc در لاینرها و قطعات transition p...
