abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
ثابت پایداری کمپلکس های هیستیدین با فلزات آهن(iii)، کبالت(ii)، نیکل (ii)، روی(ii)، مس(ii) و سرب(ii) با روش پتانسیومتری در دماهای 25، 30، 37و 45 درجه ی سانتیگراد تعیین شد. محاسبات توسط نرم افزار grcbeta که بر اساس روش تغییر یافته ژروم طراحی شده، صورت گرفته است. تیتراسیون پتانسیومتری در حلال آب ومخلوط آب-دی اکسان (70-30)% و (50-50)% انجام شد و نتایج با هم مقایسه گردید. قدرت یونی محلول توسط سدیم ن...
Copper coordination to soluble oligomers of the English (AβH(6)R) mutant of the amyloid-β peptide is probed. Cu(II) coordination yields a square planar (N/O)4 coordination environment, while reduction yields an O2 inert linear bis-His Cu(I) centre.
Background : One of the indices of health care development is the use of HIS, but it is not supporting the nursing process as a scientific method. So, this study was done in order to optimize Hospital Information System (HIS) in cardiac care unit with the approach of “nursing care using scientific method”. Materials and Methods: This study is a part of a participatory action research which w...
one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...
