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...

We study Andreev states near atomic scale modulations in the pairing potential in both s- and d-wave superconductors with short coherence lengths. For a moderate reduction of the local gap, the states exist only close to the gap edge. If one allows for local sign changes of the order parameter, however, resonances can occur at energies close to the Fermi level. The local density of states (LDOS...
