We have recently synthesized [Ni (MAP) ] complex [H-MAP= 2- (methylamino) pyridine]. 2- (Methy1amino)pyridine reacts with MeLi in THF and generates the lithium salt (Li-MAP). Further reaction of NiCl with two equivalent of this ligand in THF leads to the formation of a dark red solution. Analytical data, molecular weight, and magnetic susceptibility of this complex confirm the formula [N...

The study of knowledge has always been one of the central issues of the AI research. The general belief has been that "the more you have it the better you are." It was well understood that incorrect knowledge is harmful and should be avoided, but correct knowledge had been mostly considered beneficial. The potential harmfulness of correct knowledge received attention in very few early works but...
رنگگیری ناقص پوست میوۀ سیب میتواند یکی از دلایل اصلی کاهش بازارپسندی رقمهای قرمز باشد. در این پژوهش، همبستگی بین میزان آنتوسیانین کل و شاخص رنگ پوست میوه با میزان و نسبت عنصرهای کانی در بیست باغ سیب رقم ʼرد دلیشزʻ بررسی شد. برای این منظور، از هر باغ سه گروه بیستتایی میوه با سه رنگ قرمز تند، متوسط و ضعیف در مرحلۀ بلوغ تجاری برداشت شدند. شاخص رنگ پوست میوه مانند زاویۀ هیو (h°)، روشنی (L*)، خل...
Background and Objectives: There are some indices for scientometrics including counting the number of scientific publications and the number of citations to these publications. Hirsch Index(H-index)is widely accepted for scientometrics because it has both qualitative and quantitative components for scientometrics. This study evaluated the scientific outputs of faculty members of Rafsanjan Unive...

We show there exists a continuous compactly supported function ' de ned on the reals satsifying '(x) = c0'(2x) + c1'(2x 1) + c2'(2x 2) if and only if c1 = 1, c0 + c2 = 1, and jc0j; jc2j < 1. The functions ' are examples of scaling functions from the theory of wavelets. x
Monitoring System has been forthcoming (see March 1996 Colorado Dairy News). Although Colorado was not one of the states sampled. The results on a regional and national basis provide our producers with thoughtprovoking information. The Colorado Dairy News will feature topics from this study in this and future issues. We appreciate the assistance of Dr Scott Wells and his associates at NAHMS wit...
