abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
Sheldon K. Friedlander and David Y. H. Pui Department of Chemical Engineering, 5531-K Boelter Hall, University of California, Los Angeles, 405 Hilgard Avenue, Los Angeles, CA 90095, USA (Tel: 310-825-2206; Fax: 310-206-4107; E-mail: [email protected]); Director of the Particle Technology Laboratory, Mechanical Engineering Department, University of Minnesota, 111 Church St., S.E., Minneapolis, M...
We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...
Molecular dynamics simulations and fluorescence anisotropy decay measurements are used to investigate the rotational diffusion of anthracene in two organic solvents—cyclohexane and 2-propanol—at several temperatures. Molecular dynamics simulations of 1 ns length were performed for anthracene in cyclohexane ~at 280, 296, and 310 K! and in 2-propanol ~at 296 K!. The calculated time constants for ...
Simulations of small unilamellar lipid bilayer vesicles have been performed to model their response to an instantaneous rise in temperature, starting from an initial low-temperature structure, to temperatures near or above the main chain transition temperature. The MARTINI coarse-grained force-field was used to construct slabs of gel-phase DPPC bilayers, which were assembled into truncated icos...

بررسی برهم کنش های قوی هادرون ها انگیزه اصلی مطالعه اتم های اگزوتیک بوده است. برای این منظور ذره ای با بار منفی که می تواند مزون یا باریون باشد، وارد محیط شده و جایگزین الکترون اتمی شده و اتم هادرونی بسیار برانگیخته تشکیل می شود. ذره طی فرایندهای گذار آبشاری به حالت های پایین گذار کرده و با هسته برهم کنش قوی انجام می دهد، که در نهایت منجر به جذب توسط هسته خواهد شد. یکی از این نوع اتم...
The aim of this study is to investigate the effects different rates N, Mg and Fe applications on mineral content parsley leaves. experiment was carried out in a greenhouse according randomized plot design with three replications. Seven dose treatments were designed as 130, 160, 190, 220, 250, 280 310 kg per ha N ammonium nitrate (33% N), 40, 80, 120, 200, 240 magnesium sulphate (16% MgO) 8, 16,...
BACKGROUND Current metastatic colorectal cancer (mCRC) therapy uses monoclonal antibodies against the epidermal growth factor receptor. This treatment is only useful in the absence of K-RAS gene mutations; therefore the study of such mutations is part of a personalized treatment. The aim of this work is to determine the frequency and type of the most common K-RAS mutations in Mexican patients w...
در این پایان نامه به مطالعه "مدول های -k ناتکین"و بر مبنای مقاله ی ذیل می پردازیم: on k-nonsingular modules and applications,communications in algebra. 35, 2960– 2982,(2007). ابتدا به معرفی مفهوم -k ناتکینی یک مدول پرداخته، نشان می دهیم که هر خانواده از مدول های -k ناتکین شامل مدول های ناتکین و مدول های چندشکل می باشد. خواص مدول های -k ناتکین را مورد ...
