طیف سنجی رامان ارتقا یافته سطحی (sers) یک روش طیف سنجی رامان است? که سیگنال رامان ارتقا? یافته بزرگی را برای مولکول های هدفی که بر روی سطوح فلزی معین جذب سطحی شده?اند، به دست می?دهد. در این پژوهش ابتدا دو زیرلایه مختلف sers ساخته و مشخصه?یابی شدند. زیرلایه های ساخته شده عبارتند از: 1) نانو ذرات نقره کلوئیدی ساخته شده به روش لی و میسل، 2) نانو ذرات نقره کلوئیدی ساخته شده به روش کریتون اصلاح ...
INTRODUCTION The purpose of this study is to analyze national and institutional trends in shoulder arthroplasty utilization by race. METHODS The Nationwide Inpatient Sample (NIS) was analyzed to determine racial trends in shoulder arthroplasty utilization nationally. An institutional database was then utilized to retrospectively identify all patients undergoing shoulder arthr...
black humor plays a crucial role in fulfilling langston hughes's anti-racist purposes as an integral notionin his poetry. accordingly, translation(s) of his poetry are to benefit from the same indexes onthe basis of equivalent effect principle. on this account, 33 black-humor-rich poems of hughes, translatedby ahmad shamloo, yaghma golruee and hassan fayyad, were selected to be analyzed contras...
the identification of different species of simuliidae, also called “black fly”, is based on particular structure of oral and terminal appendages of their larvae add also on the special morphology of adults and pupaes. because of their considerable flight range, the problem of finding their resting places, and also the difficulties of collecting the adult flies, breeding of this insect, in the l...
common drying systems, including hot air convection, infrared, vacuum and ir-convective were employed to investigate and analyze the drying process of mulberry fruits. to evaluate the effect of pretreatment on the drying phenomenon, samples were pretreated by being subjected to: microwaves, chemical preparation, mechanical as well as blanching approaches. results revealed that the microwave pre...
study of agronomic characteristics and advantage indices in intercropping of additive series of chickpea (cicer arietinum l.) and black cumin (nigella sativa l.) abstract in order to evaluate quantitive and qualitive yield of chickpea (cicer arietinum l.) and black cumin (nigella sativa l.) in intercropping of additive series, a field experiment was arranged in a randomized complete block desig...
Black bean genotypes have high resistance to the important pests and diseases of common bean. To evaluate the effectiveness of four genes in the direct (plant negatively effects on biology and reproduction of herbivore by its physical and biochemical barriers) and or indirect)by attracting natural enemies of herbivores(in black beans against two spotted spider mite, expression levels of these g...
In this letter, we consider static black hole in f(R) gravity.We take advantage from corrected entropy and temperature and investigate such black hole. Finally, we study the $ P - V $ critically and phase transition of corrected black hole with respect to entropy and temperature. Here also, we obtain the heat capacity for the static black hole in $ f(R) $ gravity. This calculation help us...
The aim of this study was to evaluate the toxicity of black cumin (Nigella sativa) extract on germination and growth of flixweed (Descurainia Sophia) seedlings grown in wheat (Triticum aestivum) fields, isolation and identification of important bioactive compounds of its aqueous extract. Two factorial experiments were conducted in a completely randomized design with three replications. In each ...
