Reversed micellar two-phase extraction is a developing technique for protein separation. Introduction of an affinity ligand is considered to be an effective approach to increase the selectivity and capacity of reversed micelles. In this article, Cibacron Blue F3G-A (CB) as an affinity ligand was immobilized to reversed micelles composed of soybean lecithin by a two-phase reaction. The affinity ...

The increasing use of digital technologies has significantly reshaped marketing and consumer behavior (CB) as online communities cutting-edge innovations such artificial intelligence (AI) disrupt advance attitudes on specific products services. As such, that are supported by AI creating new knowledge from interactions through platforms like social media consumers share experiences or Since is d...

The monoid $Cb$ of name substitutions and the notion of finitely supported $Cb$-sets introduced by Pitts as a generalization of nominal sets. A simple finitely supported $Cb$-set is a one point extension of a cyclic nominal set. The support map of a simple finitely supported $Cb$-set is an injective map. Also, for every two distinct elements of a simple finitely supported $Cb$-set, there exists...

In this study for the first time a new description of compressibility factor is rendered based on the virial expansion. The compressibility factor as a function of M-factor is qualitatively and quantitatively expressed. At first, we present how may the third, fourth and higher order virial coefficients be logically ignored in order to simplify the virial equation. The results show, wh...

the compressibility factor of nonassociated chain molecules composed of hard convex core yukawa segments was derived with saft-vr and an extension of the barker-henderson perturbation theory for convex bodies. the temperature-dependent chain and dispersion compressibility factors were derived using the yukawa potential. the effects of temperature, packing fraction, and segment number on the com...

بیش از یک دهه است که روشهای بدون جزء (Meshless) مورد توجه ویژه ای در حل مسائل درمهندسی و علوم قرار گرفته اند. عمده تفاوت این روشها با روش اجزاء محدود در توابع شکل آنهااز تقریب حداقل مربعات (Diffuse Element Method) می باشد. در این میان، در روش اجزاء پراکندهاز تقریب حداقل مربعات (Element-Free Galerkin Method) و در روش بدون جزء گالرکین (LS)جهت تشکیل توابع شکل استفاده می شود. برای مقایسه تحلیل انجا...

The experimental determination of protein compressibility reflects both the protein intrinsic compressibility and the difference between the compressibility of water in the protein hydration shell and bulk water. We use molecular dynamics simulations to explore the dependence of the isothermal compressibility of the hydration shell surrounding globular proteins on differential contributions fro...

معادله بوسینسک پایه و اساس بسیاری از حل های تحلیلی و عددی در زمینه زهکشی در شرایط غیرماندگار می باشد. در بسیاری از راه حل های تحلیلی فرض می شود که محیط متخلخل (خاک) همگن است. فرض همگن بودن خاک دور از واقعیت است و باعث ایجاد خطا در نتایج حاصل از مدل های ریاضی می شود. در این تحقیق با فرض تغییرات توانی نرخ جرم در داخل حجم کنترل و استفاده از سری تیلور مرتبه کسری، معادله بوسینسک مرتبه کسری به دست آم...
