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...

Background: MTHFR promoter hypermethylation in testicular biopsies of patients with non-obstructive azoospermia: the role of epigenetics in male infertility. Materials and Methods: DNA from peripheral blood (PB) samples of 50 patients with NOA and 50 fertile men (controls) as well as DNA from testicular biopsies of 32 patients with NOA and five patients with obstructive azoospemia, but normal s...
