OBJECTIVES To determine the effect of applying the PRECEDE educational model as a framework for controlling iron defiency anaemia (IDA) among high school girl students. METHODS This Quasi-experimental study was conducted between April and July 2009 at Isfahan, Iran. Using a simple random sampling technique, a total of 72 students were selected and divided in two intervention and control group...

Petrography and chemistry of minerals showing that Eocene alkaline volcanic rocks in southwestern of Germi (Talesh zone, NW Iran) mostly have basaltic composition. Mineralogically these rocks are composed of diopsidic clinopyroxene and labradoritic plagioclase phenocrysts. The microlithic and glassy groundmass composed of sanidine, clinopyroxene, biotite, pargasitic amphibole and magnetite asso...

With the aim of gauging their potential as conducting or superconducting materials, we examine the crystal structures and magnetic properties of the roughly one hundred binary, ternary, and quaternary Ag(II) and Ag(III) fluorides in the solid state reported up to date. The Ag(II) cation appears in these species usually in a distorted octahedral environment, either in an [AgF](+) infinite chain ...

objective(s): silver nanoparticles (ag nps) are not only specific physical and chemical properties but also are considered for their antibacterial activity and ecofriendly.materials and methods:in this study a simple, cost effective biologically method for ag+reducing to ag nps using echinops extractas a stabilizer, and reducing agent.ag nps were analyzed using uv-vis spectrometry,tem, xrd and ...

‎the annihilator graph $ag(r)$ of a commutative ring $r$ is a simple undirected graph with the vertex set $z(r)^*$ and two distinct vertices are adjacent if and only if $ann(x) cup ann(y)$ $ neq $ $ann(xy)$‎. ‎in this paper we give the sufficient condition for a graph $ag(r)$ to be complete‎. ‎we characterize rings for which $ag(r)$ is a regular graph‎, ‎we show that $gamma (ag(r))in {1,2}$ and...

conclusions silver nanoparticles have high therapeutic activity against mrsa, thus can be suggested as an alternative or adjuvant with antibiotics for mrsa treatment. further studies are required to understand the synergistic effect of ag-nps combinations and to assess the safety and efficacy of new antibiotic-ag-nps combinations. background methicillin-resistant staphylococcus aureus (mrsa) ar...

the aim of this short note is to introduce the concepts of prime and semiprime ideals in ordered ag-groupoids with left identity. these concepts are related to the concepts of quasi-prime and quasi-semiprime ideals, play an important role in studying the structure of ordered ag-groupoids, so it seems to be interesting to study them.

in this study, we investigated the antifungal effects of silver nanoparticles (ag-nps) on candida albicans (atcc 5027), saccharomyces cerevisiae (atcc 5027). investigating method by using minimum inhibitory concentration (mic) technique, some of drugs including amphotericin b, fluconazole and synthesized ag-nps have been obtained on the fungi and the changes on membrane reactions of yeasts have...
