The peripheral vestibular system is critical for the execution of activities of daily life as it provides movement and orientation information to motor and sensory systems. Patients with bilateral vestibular hypofunction experience a significant decrease in quality of life and have currently no viable treatment option. Vestibular implants could eventually restore vestibular function. Most vesti...
Aneurysms of the common iliac artery (CIAA) are most commonly seen in association with an abdominal aortic aneurysm (AAA). Isolated CIAAs, in the absence of an AAA, are uncommon. Similar to AAAs, CIAA may develop intraluminal thrombus (ILT). As isolated CIAAs have a contralateral common iliac artery for comparison, they provide an opportunity to study the haemodynamic mechanisms behind ILT form...
nothing affects learners more than assessment, so it is important to involve them in assessment process. involvment of learners in assessment helps them to become autonoumos learners. despite this importance iranian learners specialy javanroodian ones are not activily involved in the process. hence the aim of this thesis is to invesrtigate thier ability in th eassessment process

In this research, samples of AlMg0.7Si aluminum alloy are deformed up to three passes using equal channel angular pressing (ECAP). Formation of a sub-micron structure after three passes of ECAP is demonstrated. Microstructural stability of the samples is investigated at temperatures of 300-500 °C. At 300 °C, fine recrystallized structure forms after 10 min which remains stable when the ...
With experimental animals, the electrically evoked compound action potential (ECAP) can be recorded from multiple sites (e.g., round window, intracranial and intracochlear sites). However, human ECAPs are typically recorded from intracochlear electrodes of the implanted array. To bridge this difference, we obtained ECAPs from cats using both intracochlear and nerve-trunk recording sites. We als...
Titanium is widely used in biomedical materials, particularly in dental implants, because of its excellent biocompatibility and mechanical characteristics. However, titanium implant failures still remain in some cases, varying with implantation sites and patients. Improving its overall performance is a major focus of dental implant research. Equal-channel angular pressing (ECAP) can result in u...
روش ecap یکی از مورد توجه ترین روش ها برای چگالش پودرها می باشد. علت به این موضوع بر می گردد که در چگالش پودر به روش مکانیکی حضور کرنش های برشی اهمیت فراوانی دارد. در این پژوهش از فرایند پرس کردن در دو کانال هم مقطع زاویه دار (ecap) برای ساخت کامپوزیت آلومینیوم-نانولوله های کربنی استفاده گردید. نانو لوله های کربنی با استفاده از روش آسیاب کاری گلوله ای شافتی و آلتراسونیک به صورت یکنواخت و غیر آگ...
