in present studies the synthesis, characterization and biological properties ofoxovanadium(iv) coordination compounds of 4[n-(4′-ethylbenzalidene)amino] antipyrinethiosemicarbazone (ebaapts) and 4[n-(2′,4′-dimethylbenzalidene)amino] antipyrinethiosemicarbazone (dmbaapts) with the general composition vox2l (x = c1-, br-, i-, no3-or ncs-) and vo(cio4)2(l)h2o (l = ebaapts or dmbaapts) are describe...

frasnian - famennian boundary in the kal-e-sardar section (east of tabas, central iran) is investigated on the basis of conodonts. distribution of thirty-three species and subspecies in the stratigraphic column enables us to recognize a barren interval and five biozones; upper rhenana, upper part of upper rhenana - linguiformis, lower to middle triangularis, upper triangularis, lower crepida. b...

Atherosclerosis, the leading cause of death in Westernized countries, derives from a non-resolving inflammation of the large arteries. A critical step in the initiation of an atherosclerotic plaque is the expansion of intimal space (the area between the endothelial cell (EC) lining and the medial smooth muscle cell layer) in susceptible regions of arteries (Tabas et al, 2007). The disease-prone...

In this paper, torsional behavior of asymmetric structures with fixed base and isolated base has been compared. Studied Structures are three-dimensional, three and eight story steel structures whose nonlinear time history analysis was conducted based on the records of El Centro earthquake (1940), Tabas earthquake (1978), and Bam earthquake (2003). Analysis results show the efficiency of seismic...

introduction & objective: the brain choroids plexus (bcp) plays an important role in the cerebrospinal fluid (csf) production, but its characterization is still incomplete. collagen type iv, is one of the most important proteins of basement membrane (bm) and extracellular matrix (ecm) of bcp. in the present study we investigated the differential period of type iv collagen in basement membrane o...
