In the present century, the emergence of issues such as population growth, public demand for living or working in urban centers, increasing use of land have allowed for existence of high rise residential complexes necessary in most major cities of the world. Despite their benefits and advantages, high-rise residential complexes have also given rise to some limitations and threats and have gr...
Nowadays, sport complexes are one of the most important parts of the universities that play a key role in improving the quality of studentschr('39') life and enhancing their desirable living standards, so that It is important to pay attention to the concept of forming these spaces throughout history and to suggest ways of promoting their position in universities and clarify their criteria and s...
This paper is concerned with the derivation and properties of differential complexes arising from a variety problems in equations, applications continuum mechanics, relativity, other fields. We present systematic procedure which, starting well-understood such as de Rham complex, derives new deduces old. relate cohomology output complex to that input show has closed ranges, and, consequently, sa...
Let $mathcal{X}$ be a class of $R$-modules. In this paper, we investigate ;$mathcal{X}$-injective (projective) and DG-$mathcal{X}$-injective (projective) complexes which are generalizations of injective (projective) and DG-injective (projective) complexes. We prove that some known results can be extended to the class of ;$mathcal{X}$-injective (projective) and DG-$mathcal{X}$-injective ...
In this review article, the methods of preparation of copper(l) crunplexC(", stereochemistry (crystal and molecularstrucmres) ofmono-, bi-, trio, te1ra1., penta-, hexa-, acta-, dodeca-, and finally polynuclear complexes have been studied. In addition, metal-metal interaction in some cases, have ~ discussed.. For the first time, four new ropper(I) complexes (mono-, di-, and henmer) have bee...
Glipizide has been found to form inclusion complexes with β-cyclodextrin (β-CD) in solution and in solid state. The present study was undertaken to determine a suitable method for scaling up glipizide-β-CD inclusion complex formation and to evaluate the effect of some parameters on the efficiency of complexation. The solid inclusion complexes of glipizide and β-CD were prepared at a molar...
macrocyclic heterobinuclear zn(ii)–cu(ii) complexes with phenol based dicompartmental ligands possessing contiguous hexa- and penta-coordination sites were prepared by a stepwise procedure. the ligands include similar n4o2 and dissimilar n(imine)3o2 and n(amine)3o2 coordination sites sharing two phenolic oxygen atoms. the six-coordination site comprises two pyridyl pendant arms on the amine nit...
Introduction: The design and implementation of large-scale commercial complexes in the metropolis of Tehran have flourished for over a decade. Most of these complexes have easily attracted various age groups. Some are more successful, and some lose their customers after a period of prosperity. Public areas' forms indicate entertainment's superiority over shopping. Also, the activities in comple...
In depth interaction studies between calf thymus deoxyribonucleic acid (CT-DNA) and a series of four structurally relative palladium(II) complexes [Pd(en)(HB)](NO3)2 (a-d), where en is ethylenediamine and heterocyclic base (HB) is 2,2'-bipyridine (bpy, a); 1,10-phenanthroline (phen, b); dipyridoquinoxaline (dpq, c) and dipyridophenazine (dppz, d) (Figure 1), were performed. These studies have b...
Herein, a theoretical study on the stability of some vic-dioxime complexes of Ni(II), Pd(II) and Pt(II) in gas and aqueous phases is reported. The DFT/M06/SDD and DFT/M06/6-31G+(d,p) levels of theory were adopted for the metal ions and for every other element respectively. Structural analyses of investigated complexes have revealed square planar geometries stabilized by two O–H⋯Cl hydrogen bond...
