هدف از این تحقیق بررسی برخی عوامل ادراکی واحساسی یعنی استفاده از شیوه های یادگیری زبان ، انگیزه ها ونگرش نسبت به زبان انگلیسی در رابطه با زمینه زبانی زبان آموزان می باشد. هدف بررسی این نکته بود که آیا اختلافی چشمگیر میان زبان آموزان دو زبانه و تک زبانه در میزان استفاده از شیوه های یادگیری زبان ، انگیزه ها نگرش و سطح مهارت زبانی وجود دارد. همچنین سعی شد تا بهترین و موثرترین عوامل پیش بینی کننده ...
15 صفحه اولThe Role of Metallic Substrate of Hydroxyapatite Coated Dental Endodontic Implants in Clinical and Pathological Success
Hydroxyapatite coatings have been used on metallic substrates in a variety of applications, including modifying the surface of human implants, bone osseointegration and biological fixation. In this paper, the effects of various kinds of metallic substrate on clinical and pathological results of in vivo tests are presented. Four kinds of endodontic implants i.e, stainless steel, cobalt base all...

متن کاملChemical Modification of Hydroxyapatite Ceramic Surface by Calcium Phosphate Coatings and In- Vitro Osteoblast Response
The surfaces of hydoxyapatite ceramics were modified by the precipitation of octacalcium phosphate coating from aqueous solution and the biomimetic method synthesized nanohydroxyapatite coatings. Both coatings were deposited as continuous and uniform layers. It was demonstrated that the octacalcium phosphate coating was inappropriate for in-vitro osteoblast proliferation despite of good initial...
متن کاملNanoindentation Study of Phase-pure Highly Crystalline Hydroxyapatite Coatings Deposited by Microplasma Spraying
The present contribution has originated from a critical biomedical engineering issue e.g., loosening of metallic prostheses fixed with poly(methyl methylacrylate) (PMMA) bone cement especially in the case of hip joint replacement which ultimately forces the patient to undergo a revision surgery. Subsequently surgeons invented a cementless fixation technology introducing a bioactive hydroxyapati...
