Heterogeneous pyritaceous-polymetallic and copper-zinc-pyrrhotine deposits on the South slope of the Greater Caucasus are located in the Lower-Middle Jurassic terrigenous sediments. They were formed under a wide variation of physico-chemical parameters of mineral formation and are characterized by specific mineralogical-geochemical peculiarities. Ore-formation occurred in three stages. In the f...
In this study, the effect of cold rolling process on the microstructure and texture evolution in 1wt. % Si non-oriented electrical steel was investigated. For this purpose, all samples were processed through single-stage hot rolling at 1100 ° C and two-stage cold rolling (cross rolling and unidirectional rolling) with intermediate annealing at 650 °C for 35 seconds. Finally, all of them were fu...
The effect and arrangement of cytoskeleton (microtubules, microfilaments and neurofilaments) in neurulation of chick embryo examined by immunoperoxidase method from stage 6 to stage 12. The results were as follows: 1) Microtubules aggregated in the perinuclear region from which they radiated to take longitudinal course beneath the membrane. 2) Microfilaments were aggregated in the apical ends (...
In order to investigate the effect of different irrigation regimes on some agronomic and physiological characters of three chickpea cultivars (Jam, 301 and Pirooz), a field experiment was conducted in 1998 at the Agricultural Research Farm of Tabriz University, Tabriz, Iran. A split plot experiment based on a randomized complete block design with three replications was used, in which irrigation...

Background: The aim of our study was to compare the resulting from transfer of embryos that cryopereserved in cleavage stage after thawing and transfer of embryos after thawing and culture in sequentional media until blastocyst formation. Materials and Methods: In this prospective clinical study, we have evaluated 128 cycles in women undergone in vitro fertilization (IVF) or intracytoplasmic sp...
