Cities as the most complex man-made structures have been always exposed to natural and man-made hazards; these unpredictable risks have imposed seriousimpacts on urban areas. Meanwhile Urban Resiliency is the ability of cities to respond quickly to inappropriate and unpredictable conditions, which continiues stronger than before, consistent to the new conditions. Karaj as one of the metropolise...

the genus azolla forms a group of small-leafed, floating aquatic ferns native to the tropics, subtropics, and warm temperate regions of africa, asia, and america. for several decades, these ferns have been utilized for various purposes: e.g. as green manure, feed for animals, but also for the removal of different metals (e.g. hg, pb, cr and cd) through wastewater treatment or for elimination of...

the purpose of this research is to prioritize the indexes of discretion, heterogeny and autogeny factors in order to analyze and evaluate their readiness for ideal situation of central bank of the islamic republic of iran (cbi). this research is an exploratory kind and in terms of method is a survey kind. the data collection tool is questionnaire. after two delphi cycles, in final questionnaire...

Many biological activities originate from interactions between small-molecule ligands and their protein targets. A detailed structural and physico-chemical characterization of these interactions could significantly deepen our understanding of protein function and facilitate drug design. Here, we present a large-scale study on a non-redundant set of about 20,000 known ligand-binding sites, or po...

Objective: To investigate the cytomorphological and physico-chemical characteristics of Sida rhombifolia. Methods: Fresh leaves, stems and roots were studied for microscopical characters and dried powder of leaves, stems and roots were subjected to physico-chemical analysis using standard methods. Results: The detail microscopy of leaf revealed the presence of paracytic stomata, unicellular cov...

Due to the existence of terrestrial barriers to freshwater fish dispersion, it is believed that its distribution is strongly associated with historical factors related to the formation of the habitats they occupy. By the other hand, some studies reveal the influence of abiotic conditions (such as size of water bodies, pH, conductivity) on the composition of fish fauna occurring in small streams...

Physico-chemical properties reflect the functional and structural characteristics of a protein. The comparative study of the physicochemical properties is important to know role of a protein in exploring its molecular evolution. A number of online and offline tools are available for calculating the physico-chemical properties of a single protein sequence. However, a tool is not available for a ...

In many different fields of mathematics and physics Poincaré found many uses for the idea of a group, but not for group theory. He used the idea in his work on automorphic functions, in number theory, in his epistemology, Lie theory (on the so-called Campbell–Baker–Hausdorff and Poincaré–Birkhoff–Witt theorems), in physics (where he introduced the Lorentz group), in his study of the domains of ...
