Abstract Eu:CaAl 2 O 4 , Eu:SrAl and Eu:BaAl crystals with various dopant concentration were synthesized by the optical floating zone method, photoluminescence, scintillation, afterglow properties investigated. Under X-ray irradiation, exhibit a broad emission band at 440, 520, 500 nm due to 5d-4f transitions of Eu 2+ respectively. The decay time constants are consistent typical values . Photol...
This research was designed and implemented to determine the effect of different irrigation regimes on the grain yield, dry matter, tiller number per unit area, degree of maturity, panicle harvest index, percentage of leaf rolling, day to 50% flowering, and the physiological maturity of rice genotypes, using a split plot randomized complete block design in two years (2014 and 2015). Four irrigat...
A structural-magnetic models of the orthorhombic and triclinic modifications arsenates Cu4O(AsO4)2 isotypic phosphates Cu4O(PO4)2 has been built analyzed. Their base elements are complicated ribbons composed antiferromagnetic Cu4 tetrahedra. Structurally, these tetrahedra have no shared copper atoms; however, there strong (AFM) ferromagnetic (FM) couplings between them, both within them. It est...
Vaccination of livestock with effective vaccine could be one of the control methods for hydatid cyst. In this study a new recombinant vaccine (Eg95) from New Zealand was prepared and used. Thirty health sheep from the same race and identical age and sex were selected. There was no history of any past vaccination or disease in selected animals. Animals were randomly categorized to four groups. O...
