چکیده اسانس گیاهان خشک شده در سایه را به دو روش استخراج کردیم : -1 روش تقطیر با آب -2 روش میکرو استخراج فاز جامد در فضای فوقانی سپس کروماتوگرام های بدست آمده را توسط دستگاه gc/ms مورد تجزیه وتحلیل قرار دادیم . ترکیبات اصلی اسانس مخلوط اجزاء(گل، ساقه، برگ)گیاه جاشیر( (prangos ferulaciaوگیاه کماferula ovin) ) به روش تقطیر با آب در جداول زیر آورده شده است .
In patients with loss of vestibular functions, we studied psychophysically the self-motion perception for 'trunk in space' and 'head in space' during various combinations of horizontal head and trunk rotation in the dark. The results were compared to those of normal subjects. For their 'trunk in space' perception, the subjects relied on their internal image of space, derived from the vestibular...
Introdution: The aim of this study was to evaluate and benchmark EGSnrc code in the simulation of 18 MV photon beam produced by Siemens Oncor® linear accelerator. Methods: This study was conducted in a comparative and simulation based on experience method. The Beamnrc code was used to model the accelerator head and generate phase space files. The phase space files were obtained with the fo...
non-penetrating head injuries associated with skull base fractures can lead to the development of pneumocephalus upon airs ingress, which leads its course in the subarachnoid space. intracerebral air accumulation is rare and ensuses when a paranasal sinus fracture is associated with a ensues when a paranasal sinus fracture is associated with a nearby parenchymal contusion. a 25-year old man is ...
Background: One of the main problems of dedicated IORT accelerators is to determine dosimetric characteristics of the electron beams. Monte Carlo simulation of IORT accelerator head and produced beam will be useful to improve the accuracy of beam dosimetry.Materials and Methods: Liac accelerator head was modeled using the BEAMnrcMonte Carlo simulation system. Phase-space files were generated at...
Aggressive fibromatosis also known as extra abdominal desmoid tumor is an uncommon benign tumor of soft tissue origin with fibroblastic proliferationSince the tumor is locally aggressive, the lesion may be misdiagnosed as low -grade fibrosarcoms. It accounts for 0.03% - 0.1% of all body tumors and 3% of all soft tissue tumors. Only 10% to 15% of these lesions occur in head and neck, usually in ...
