in recent decades, attention to contamination propagation into soils and underground water has increased, which has led to a rise in the studies on soil contamination problems and methods of in-situ remediation. in this research, effective parameters on oil contamination propagation in soils and underground water have been investigated using fem in order to determine propagation patterns. the m...
In situ hybridization (ISH) is a method that uses labeled complementary single strand DNA or RNA to localize specific DNA or RNA sequences in an intact cell or in a fixed tissue section. The main steps of ISH consist of: probe selection, tissue or sample preparation, pre-hybridization treatment, hybridization and washing, detection and control procedure. Probe selection is one of the important ...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
We have obtained detailed three-dimensional images of in situ cross-bridge structure in insect flight muscle by electron microscopy of multiple tilt views of single filament layers in ultrathin sections, supplemented with data from thick sections. In this report, we describe the images obtained of the myac layer, a 25-nm longitudinal section containing a single layer of alternating myosin and a...
در این تحقیق ترکیب شیمیایی، حجم گاز تولیدی، قابلیت هضم آزمایشگاهی، تجزیه پذیری موثر و شاخص ارزش غذایی ماده خشک، ماده آلی، پروتئین و الیاف نامحلول در شوینده خنثی پوست سبز گردوی فرآوری شده با قارچ نوروسپورا سیتوفیلا بر روی سه رأس گوسفند نر بالغ کرمانی دارای فیستولا مورد مطالعه قرار گرفت. داده های جمع آوری شده در قالب طرح کاملا تصادفی آنالیز آماری شدند. با فرآوری پوست سبز گردو با قارچ نوروسپورا سی...
in studying of the in situ gravitational concentration process part feature for placer, the technological ability to transform the in situ massif placer structure is evident. the two main processes involved in altering the massif in situ have been examined and outlined in detail. the in situ disintegration of massif material results in a new massif gravitational stratification structure. regula...
abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...
چکیده: فنولوژِی یکی از مباحث علم وسیع اکولوژی است. مطالعه فنولوژی برای تنظیم برنامه های تغذیه ای دام و شناخت خوشخوراکی و ارزش غذایی گونه های گیاهی در مراحل مختلف حیاتی در نیاز غذایی دام ها حائز کمال اهمیت است. هدف از این پژوهش، بررسی اثرات مراحل مختلف فنولوژیکی بر روی کیفیت چهار گونه علوفه از گیاه هان هالوفیت (نمک دوست) به نام های آتریپلکس (atriplex loucoclada)، بونی (aeluropus lagopoides)، لول...
