In this work we study the effect of some electrical prosperities on synthetic rubber reinforced with carbon black diluted in heptanes with concentrations from 0.2% gm/mole to 2.0% gm/ mole in temperatures range (100, 150, 200, 250, 300) C associated with amount weight of black carbon 5wt% added to the diluted rubber. The results of electrical properties measurement of Buna rubber reinforced wit...

We report Zeeman infra-red spectroscopy of electronic-nuclear levels 5I8 →5I7 transitions Ho3+ in the C4v(F−) centre CaF2 with magnetic field along ⟨111⟩ direction crystal. Transitions to lowest 5I7 state, an isolated electronic doublet, and next group states, a pseudo-quadruplet consisting doublet two nearby singlets, exhibit strongly non-linear splittings intensity variations. Simulated spect...

Introduction: Present children are the investments of community in the future. Preparing children health which leads to the stability of community health, provided to accurate implementation of educational and health programs in the community and especially in mothers. So it is necessary to determine the relationship between parents' literacy with growth rate in children.   Materials and Method...

Background: The process of implantation involves the interaction of the human embryo and the uterine epithelium. Failure of implantation is a major reason for infertility in women and the inability to achieve endometrial receptivity is responsible for much of the failure of reproductive technologies. Management of repeated implantation failure despite transfer of good-quality embryos still rema...
