the current study evaluated the effects of electron beam (eb; 10, 20, 30 and 40 kgy), urea and naoh treatments on chemical composition, phenolic compounds, in vitro gas production and in situ ruminal degradability of pistachio by-product (pb). the eb decreased (p < 0.01) neutral detergent fiber (ndf), acid detergent fiber (adf) and acid detergent lignin (adl) contents of pb. treating pb by naoh...
in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...

Introduction: Pistachio is an important export product in some countries, especially Iran. Pistachios are with the highest risk of aflatoxin contamination between agricultural products. Aflatoxin B1 is the most potent carcinogenic aflatoxins. Aflatoxins have an important role in the etiology of cancer. Undoubtedly, the major problem is, Aspergillus flavus contamination Aflatoxin pr...
We explore the potential of electron-photon colliders to measure fundamental supersymmetry parameters via the processes ee ! ~ e~ 0 (selectron-neutralino) and ee ! ~ ~ ? (sneutrino-chargino). Given the ~ 0 and ~ ? masses from e + e ? and hadron collider studies, cross section ratios (?)==(+) for opposite photon helicities determine the ~ L , ~ e L and ~ e R masses, independent of the sparticle ...
چکیده : نظریه ی شیوه ی تولید آسیایی ، اولین بار توسط مارکس و سپس در تأیید نظریات او ، در آثار انگلس مطرح شد . این نظریه علاوه بر شیوه تولید ، به بحث درباره ی ماهیت دولت در جوامع آسیایی می پردازد . در این پژوهش ، وجه تولید آسیایی و نظریات پیرامون آن در توسعه نیافتگی ایران ، مورد بحث و بررسی قرار می گیرند . مهمترین نظ the asian production theory was first introduced by marx and then was suppo...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
