گیاه pimpinella aurea dc در مرحله گلدهی از منطقه سمنان جمع آوری گردید و گیاه با روش تقطیر با آب و میکرو استخراج فاز جامد در فضای فوقانی اسانس گیری شد. بررسی ترکیبات شناسایی شده در اسانس گیاه به روش تقطیر با آب نشان داد؛آلفا-پنین(08/24?)،اکتان(86/20?)،بتا-پینن(22/11?) ، لیمونن (06/9?)، اسپاتولنول(1/5?)، n-دکان (41/4?)، ژرماکرین-d(07/3?)ترکیبات اصلی اسانس شناسایی شده (0.6/99%) می باشد. در روش میک...
Background: Fritillaria imperialis is an endangered species with pharmaceutical alkaloids that can be effective in reducing blood pressure and reducing cardiac palpitations. Objective: Comparison of head space solid phase microextraction (HS-SPME) and hydro-distillation (HD) techniques in determination of essential oils in Fritillaria imperialis Methods: Quality and quantity determination o...
abstract:assume that y is a banach space such that r(y ) ? 2, where r(.) is garc?a-falset’s coefficient. and x is a banach space which can be continuously embedded in y . we prove that x can be renormed to satisfy the weak fixed point property (w-fpp). on the other hand, assume that k is a scattered compact topological space such that k(!) = ? ; and c(k) is the space of all real continuous ...
Introduction: Retropharyngeal space schwannomas are rare entities. About 20-45% of schwannomas occur in the head and neck region; however, they represent less than 1% of all head and neck tumors. Case Report: We present the case of a 36-year-old woman complaining of dysphagia caused by a large schwannoma arising in the posterior pharyngeal wall with remarkable reduction of the oropharyngeal sp...
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 a...
The vestibular sensory apparatus and associated vestibular nuclei are generally thought to encode head-in-space motion. Angular head-in-space velocity is detected by vestibular hair cells that are located within the semicircular canals of the inner ear. In turn, the afferent fibers of the vestibular nerve project to neurons in the vestibular nuclei, which, in head-restrained animals, similarly ...
