تولید انبوه مرکبات در ایران، لزوم درجه بندی کیفی این محصولات را برای ورود به بازارهای جهانی تقاضا می کند. به همین منظور، در تحقیق حاضر، یک دستگاه سورتر (sorter) روباتیکی طراحی و ساخته شد تا بتواند میوه ها را بر اساس اندازه به سه قسمت کوچک، متوسط و بزرگ تقسیم نماید. دستگاه شامل بخش های نرم افزاری و سخت افزاری می باشد. قسمت سخت افزاری دستگاه از دو واحد تشکیل شده است. واحد اول، واحد تصویر برداری م...
Introduction: Dimensional changes in acrylic patterns during laboratory process to fabricate casting are an important issue which could lead to many clinical consequences. Microleakage, lack of retention and fitness are few of problems which could be predicted in the case of dimensional changes in acrylic patterns. So, investigating the factors which could minimize the dimensional change is nec...
purpose: to evaluate pupil dilation with intracameral injection of preservative-free lidocaine 1% during phacoemulsification. methods: this interventional case series included 31 consecutive senile cataract patients scheduled for phacoemulsification and intraocular lens (iol) implantation. pupil dilation was achieved using intracameral preservative-free lidocaine 1% without any preoperative or ...
Background and Purpose: Since molar main canal preparation faciliates a good apical obturation and provides necessary room for “post” placement. This study focuses on the outcome of two different instrumentation methods in canal diameter and remained dentin. Materials and Methods: Main canal of 60 upper and lower molars prepared in 4 groups using step back (SB) and passive step back (PSB) te...
BACKGROUND Tyrosine kinase inhibitors (TKIs) have been used as standard therapy for patients with advanced renal cell carcinoma (RCC). However, information on factors predicting response to treatment with TKIs is lacking. This study aimed to assess the association between initial tumor size, involved organs, pre-treatment C-reactive protein (CRP) levels, and reduction in tumor size in patients ...
determination of the accurate time of egg stripping after ovulation has been regarded as one of the most important factors in the successful reproduction of caspian brown trout(salmo trutta caspius). to determine the best time for egg stripping after ovulation and over- ripening of the oocyte in the caspian brown trout , the eggs of fish were retained in the coelomic cavity of females at 7 ± 6°...
PURPOSE Accurate evaluation of side branch (SB) ostium could be critical to the treatment of bifurcation lesions. We compared measured and calculated values of side branch ostial length (SBOL) in coronary bifurcation lesions with intravascular ultrasound (IVUS). MATERIALS AND METHODS Pre-intervention and post-intervention IVUS was performed in 113 patients who underwent stent implantation of ...
BACKGROUND The majority of infrarenal abdominal aortic aneurysm (AAA) repairs in the United States are performed with endovascular methods. Baseline aortoiliac arterial anatomic characteristics are fundamental criteria for appropriate patient selection for endovascular aortic repair (EVAR) and key determinants of long-term success. We evaluated compliance with anatomic guidelines for EVAR and t...
