Abstract: Nickel was electrodeposited onto copper substrates with high {111} and {400} peak intensities. The grain size of coatings deposited onto the copper substrate with a higher {111} peak intensity was finer. Spheroidized pyramid morphology was obtained at low current densities on both copper substrates. By increasing the deposition current density, grain size of the coating was increased ...
In the current work, the effect of surface morphology on light emission property and absorption behavior of quasi-columnar macro-porous silicon (PS) was investigated. PS structures with different morphology were synthesized using photo-electrochemical etching method by applying different etching current densities. SEM micrographs showed that empty macro-pores size and porosity of PS layers were...
سیلاب ورودی به مخزن سد حاوی مواد معلق زیاد بوده که اصطلاحاً جریان چگال (density current) نامیده می شود. این جریان در واقع جریان یک سیال درون سیال دیگر است که بوسیله اختلاف چگالی مابین آنها ایجاد می گردد. اختلاف در چگالی که باعث ایجاد نیروی رانش می گردد ممکن است ناشی از اختلاف درجه حرارت، وجود ذرات معلق جامد ویا مواد محلول باشد. در این تحقیق با توجه به آزمایشات سه بعدی انجام شده، گسترش عرضی جریان...
Flash sintering is one of the newest techniques for sintering ceramics to near full density. It occurs in an appropriate combination of temperature and electric field. Temperature measurement is one of the most serious challenges in this process. In the present study, we tried to model a flash sintering process of 8YSZ and 3YSZ with finite element method to make an assessment for temperature di...
OBJECTIVE To determine effects of microcurrent electrical tissue stimulation (METS) on equine tenocytes cultured from the superficial digital flexor tendon (SDFT). SAMPLE POPULATION SDFTs were collected from 20 horses at slaughter. PROCEDURE Tenocytes were isolated following outgrowth from explants and grown in 48-well plates. Four methods of delivering current to the tenocytes with a METS ...
BACKGROUND The study analyzed correlations between selected variables in cervical derangement syndromes. MATERIAL AND METHODS We analyzed data from 63 patients regarding pain (VAS, McGill Pain Questionnaire), mobility (CROM goniometer), dizziness, nausea, the duration of the current episode, and the number of previous episodes (history). Student's t and chi(2) tests and Pearson's r correlatio...
