BACKGROUND Cervical selective nerve root block (CSNRB) is a well-established, minimally invasive procedure to treat radicular cervical pain. However, the procedure is technically challenging and might lead to major complications. The objective of this study was to evaluate the feasibility of a three-dimensional puncture planning and two-dimensional laser-guidance system for CSNRB in an ex-vivo ...
INTRODUCTION Computed tomography (CT), combined positron emitted tomography and CT (PET/CT), and magnetic resonance imaging (MRI) are commonly used in head and neck radiation planning. Hybrid PET/MRI has garnered attention for potential added value in cancer staging and treatment planning. Herein, we compare PET/MRI vs. planning CT for head and neck cancer gross tumor volume (GTV) delineation. ...
In the recent decades, population of the world is increasing with more rapid growth. Almost 93% of this increase was happened in Asia, Africa and Latin America. Family planning is known a way against population growth. From 1994 family planning is replaced by reproductive health and men participation is the one of the most important aspects of that.

Anticipatory motor planning abilities mature as children grow older, develop throughout childhood and are likely to be stable till the late sixties. In the seventh decade of life, motor planning performance dramatically declines, with anticipatory motor planning abilities falling to levels of those exhibited by children. At present, the processes enabling successful anticipatory motor planning ...
The aim of this study is to determine whether stereotactic body radiotherapy for multiple vertebral metastases treated with a single isocenter results in greater intrafraction errors than stereotactic body radiotherapy for single vertebral metastases and to determine whether the currently used spinal cord planning organ at risk volume and planning target volume margins are appropriate. Intrafra...
Electronic tissue compensation (eComp) is an external beam planning technique allowing user to manually generate dynamic beam fluence to produce more uniform or modulated dose distribution. In this study, we compared the effectiveness between conventional three-dimensional conformal radiotherapy (3DCRT) and eComp for whole breast irradiation. 3DCRT and eComp planning techniques were used to gen...
در عصر حاضر که رقابت بین سازمان ها بسیار گسترش یافته است، مطالعه و طرحریزی سیستم های تولیدی و خدماتی به منظور بهینه سازی عملکرد آنها اجتناب ناپذیر می باشد. بخش عمده ای از رقابت پذیری سازمان ها نتیجه رضایتمندی مشتریان آنها است. میزان موفقیت سازمان های امروزی به تلاش آنها در جهت شناسایی خواسته ها و نیازهای مشتریان و ارضای این نیازها بستگی دارد. از طرفی کوتاه کردن زمان ارائه محصول/خدمات به مشتریان...
با توجه به مطالعات انجام شده در فصل دوم پایان نامه و مطالعه جامعه آماری فصل سوم که چارچوب نظری تحقیق از آن حاصل شد و پردازش پرسشنامه ها و آزمون فرضیات تحقیق می توان در مورد نتایج آماری به موارد زیر اشاره کرد : فرضیه اول: امکان اجرای چرخه مدیریت دانش در ساختارهای مجازی دانشگاه تهران وجود دارد. طبق نتایج آزمون فرضیات تحقیق و پس از بررسی نتایج بدست آمده مقدار میانگین متغیر مورد بررسی برابر mean ...
