abstract water retention curve (wrc) is a fundamental property of soil. it is used to evaluate available water, permeability, drainage and movement of solutes. despite numerous studies on wrc of soils abroad, no local study has been carried out on charmahal-va-bakhtiari soils. the objective of this study was to compare the quality of fitting of several wrc models to lordegan soils and to select...

The total synthesis of CBD-C4 (cannabidibutol) is reported. enantioselective based on a) the use 3,5-dimetoxybenzaldehyde as starting material, b) Corey-Bakshi-Shibata reduction, c) Claisen-Ireland rearrangement, d) ring-closing metathesis, and e) not-trivial demethylation induced by sodium ethanethiolate.

در این مقاله یک مدل ریاضی برای مسئله سیستم تولیدی همکارانه ساخت بر اساس سفارش با رعایت انصاف تخصیص بار‌های تولید طراحی شده است. اهداف اصلی مدل، کمینه‌سازی هزینه‌‌های کل و حداکثر استفاده از منابع به‌منظور عادلانه شرایط عدم­قطعیت کنترل پارامتر‌های غیرقطعی روش برنامه‌ریزی فازی ‌شده نتایج نشان می‌دهد افزایش نرخ عدم‌قطعیت، می­یابد. ازآنجاکه ظرفیت کارخانه‌ها ثابت است، مقدار تقاضا، هر کارخانه نیز می­ی...

Chiral allenamides are prepared with high levels of enantiomeric purity by [2,3]-sigmatropic rearrangement of propargylic sulfimides. The required branched propargylic sulfides are prepared by an enantioselective organocatalytic aldehyde alpha-sulfenylation followed by Corey-Fuchs alkynylation.

Counseling is a professional practice. As such, ethical standards have been delineated to describe the best practices of professionals and to ensure high quality of practice (Corey, Corey, & Callanan, 2003). In countries where counseling has existed as a formal profession for some time, such as the United States (U.S.) and the United Kingdom, codes of ethics have been developed and periodically...

PNAS papers by Linus Pauling, Robert Corey, and Herman Branson in the spring of 1951 proposed the !-helix and the "-sheet, now known to form the backbones of tens of thousands of proteins. They deduced these fundamental building blocks from properties of small molecules, known both from crystal structures and from Pauling’s resonance theory of chemical bonding that predicted planar peptide grou...
