Abstract:

بررسی انتقال رقابتی درمحلول های تیزاب سلطانی و بافر 5 به­وسیله فرآیند غشا مایع توده­ای حاوی 11 , 4 ,8 ,1-تتراآزاسیکلوتترادکان-5 و 7-دیون در دمای 25 درجه سانتی­گراد انجام شد. انتقال یون­های Cr2+,Mg2+,Ni2+,Ag+و Cd2+(غلظت اولیه 01/0 مولار) از محلول تیزاب سلطانی 6 مولار و عبور از محلول دی­کلرومتان حاوی 1,4,8,11-تتراآزاسیکلوتترادکان-5 و 7-دیون به محیط آب مقطر (فاز دریافتی) پس از 24 ساعت انجام شد. سپس این انتقال به­وسیله 4 حلال آلی شامل کلروفرم، دی کلرو متان وتتراکلریدکربن و نیتروبنزن مورد بررسی قرارگرفت. روند انتقال در این حالت به­صورتی بود که از محیطی با اسیدیته کم­تر (بافر 5) به محیطی با اسیدیته بیش­تر (بافر 3) انتقال فلزات انجام می­شد. مدت زمان انتقال 24 ساعت و در شرایط دمای محیط بود. پس از انجام کار نتایج زیر حاصل شد: DCM>CF>NB>TCC در محیط بافر 5  DCM بیش­ترین انتقال در محیط   Ni2+>Cd2+>Mg2+>Ag+>Cr2+ در محیط تیزاب سلطانی+ Mg2+>Cr2+>Ag+>Ni2+>Cd2

A cyclam (1,4,8,11-tetraazacyclotetradecane)-based macrocycle bearing two benzyl and two 2-hydroxy-3,5-di-tert-butylbenzyl pendent arms was synthesized and characterized using spectroscopic techniques and single crystal X-ray diffraction. The macrocycle crystallizes in the triclinic space group P-1, with the asymmetric unit containing one-half of the molecule. The structure is stabilized by hyd...

46 There is a significant body of research examining the intelligibility of sinusoidal replicas of 47 natural speech. Discussion has followed about what the sinewave speech phenomenon might 48 imply about the mechanisms underlying phonetic recognition. However, most of this work has 49 been conducted using sentence material, making it unclear what the contributions are of 50 listeners’ use of l...

Synthesis and Characterization of 4, 11-dimethyl-1, 4, 8, 11, tetraazabicyclo hexadecane Chromium

A new complex of Chromium(III) and the cross-bridged macrocyclic ligand 4,11-dimethyl-1,4,8,11tetraazabicyclo[6.6.2] hexadecane has been synthesized. Complexation of Tungsten, Vanadium, and Molybdenum was unsuccessful. The Cr(III)(L) complex was characterized using UV-Visible spectroscopy λmax = 583nm , IR Spectroscopy, X-Ray Crystallography, and magnetic susceptibility ueff = 3.95. These tests...

A decentralized failure detection and isolation (FDI) methodology, which is robust with respect to model uncertainties and noise, is presented. Redundancy metrics are developed, and optimization problems are posed for the choices of robust parity relations. Closed-form solutions for some special failure cases are given. Connections are drawn with other disciplines, and the use of the metrics to...

27 A 3,204 bp full-length cDNA of bovine NALP9 was cloned and its genomic organisation was 28 analyzed. The 2,988 bp open reading frame covers 9 exons and encodes a deduced protein of 996 29 amino acids containing Pyrin, Nacht and leucine-rich repeat domains like the human NALP gene 30 family members. Mapping with the WGRH5000 panel and fluorescence in situ hybridisation 31 assigned NALP9 in cl...
