در پژوهش حاضر، حوضچههای آرامش نوع I،II و IIIبعد از صحتسنجی با مدل آزمایشگاهی، شبیهسازی عددی شده و ضمن بررسی پرش هیدرولیکی، پارامترهای هیدرودینامیکی جریان مانند فشار، سرعت، شدت آشفتگی و ورتیسیتی مورد مقایسه و تحلیل قرار گرفتند. از مدلهای RNG و VOF برای شبیهسازی آشفتگی و سطح آزاد جریان استفاده شده است. نتایج نشان میدهد که کارایی حوضچه نوع III و II از حوضچه نوع I بیشتر است و این کارایی ...
In the present study, various developmental stages of Liza aurata oocyte, especially IV and V stages have been described. On the basis of histological investigations, oocyte development in L. aurata comprises immature (I), the early maturing (II), the late maturing (III), mature (IV), ripe (V), and spent (VI) stages. In the stages I and II, nucleus occupied large volume of oocyte. Vacuolization...
Background: The purpose of this study was to evaluate nodal irradiation with conventional three-field's technique. Materials and Methods: Fifty patients with breast cancer were enrolled in this study. Computed tomography scans in the supine treatment position were imported into a treatment planning system. Levels I-III axillary and supraclavicular nodes were identified and their depths to the a...

Statement of Problem: Considerable response to functional orthopedic appliances treatment in class II skeletal patients occurs during pubertal growth spurt. Therefore, it seems necessary to investigate indices indicating mandibular growth pattern. It has been proved that analyzing cervical vertebral maturation stage is a more valid index than that of hand wrist. Purpose: The aim of this study w...
Introduction: The use of BMP-2 plays an important role in the treatment of extensive bone defect. However, data about the optimal dosage of BMP-2 in the massive bone defect cases is rare. Material and Method: Twenty-five SD rats were randomly divided into a control group ofhydroxyapatite (HA) alone (Group I), HA+BMP-2 1µg/mL (Group II), HA+BMP-2 5 ug/mL (Group III), HA+BMP-2 10 µg/mL (Gro...
به منظور بررسی ژئوشیمی آلی رسوبات بستر در بخش شمالی خلیج فارس، تعداد 130 نمونه رسوب سطحی برداشت گردید. رسوبات مذکور از ذرات آواری (کوارتز، فلدسپار، خرده سنگ، قطعات خرده سنگی کربناته و کانیهای رسی) و شیمیایی- بیو شیمیایی (پوسته دوکفهای، گاستروپود، فرامینیفرا، استراکود و بریوزوآ) تشکیل شدهاند. بر پایه مطالعات ژئوشیمی آلی، مقدار کربن آلی کل از 03/0 تا 48/1درصد وزنی متغیر است که در رسوبات...
Background and Objective: Histological grading has prognostic and therapeutic implications in meningioma. However, histological criteria are sometimes not fulfilled to predict the biological behavior of meningiomas. P63 gene is a novel P53 family member, known as tumor suppressor factor, with multiple isoforms and shows high expression in many normal and neoplastic human tissues. In this stu...
