Regio and stereoselective addition of a phosphine-borane to alkynyl vinyl gold(i) complexes.

Using a C++ compiler, any partial recursive function can be computed at compile time. We show this by using the C++ template mechanism to define functions via primitive recursion, composition, and μ-recursion.

we investigate the problem of the existence of a frame forright ideals of a C*-algebra A, without the use of the Kasparov stabilizationtheorem. We show that this property can not characterize A as a C*-algebraof compact operators.

Background & Aim: Policosanol is a component from main alcohol groups with long-chain that extracted from cane sugar. In the present research, the effect of policosanol was investigated on decrease of lipid metabolite levels in blood of hypercholesterolemia rats. Experimental: A number of 32 male Wistar rats race with average weight of 250 g was divided into four groups including negative cont...

the chemical composition of the essential oil of fruits of pimpinella haussknechtiiboiss.was studied by gc-ms. after gc-ms analysis, one unknown component (56.7%) was observed, which was not characterized in the gc-ms library. the essential oil of p.hauskenekhtii was injected to hplc using ymc-pak-sil column (250 × 20 mm) with gradient system of hexane (a), and hexane: ethyl acetate, 9:1 (b) to...

In this paper, we study the Krylov complexity (K) from planar/inflationary patch of de Sitter space using two mode squeezed state formalism in presence an effective field having sound speed c s $c_s$ . From our analysis, obtain explicit behavior and lancoz coefficients ( b n $b_n$ ) with respect to conformal time scale factor Since grow linearly integer n, suggests that universe acts like a cha...

This report describes the histological and immunohistochemical features of a small intestinal tumor that resembled a human gastrointestinal stromal tumor (GISTs) in a seven-year-old male cross-breed dog. This was unique because of the expression of desmin by the tumor. Grossly, the white-gray tumor measured 8.0 × 4.0 × 6.5 cm and was 760 gram in weight. It was cystic and enveloped the jejunum. ...
