Sr5Nb4O15 – Nb2O5 nanocomposites were synthesized in 2 and 4 M KOH aqueous solutions, via a non-stoichiometric 1:2 Sr:Nb molar ratio hydrothermal method at 160°C for 48 h (S1 and S2, respectively). Sr(NO3)2 and Nb2O5 were used as raw materials. The synthesized nanomaterials were characterized by powder X-Ray diffraction (PXRD) technique. It was found that Sr5Nb4O15 has been crystallized in hexa...

Introduction: Mammalian embryos as well as oocytes are prone to various doses of visible light during manipulations in laboratory. The present study was designed to investigate the effects of visible light on the development of mouse 2- cell embryos. Method: Non-pregnant female NMRI mice were super-ovulated with i.p. injection of 7.5 iu PMSG followed 48 hours later with 10 iu hCG. Forty eight h...

backgrounds: to obtain information about clinical isolates of aspergillus flavus group. methods: we examined 55 isolates [45 clinical, 10 reference (6 from culture collections, 4 local reference)] for toxicology, growth rates, and morphological and physiological characteristics. modified czapek agar (cz) and malt extract agar (mea) were used for observing microscopic morphology and measuring fu...
