in the present paper we introduce and study the notion of pairwise weakly lindelof bitopological spaces and obtain some results. further, we also study the pairwise weakly lindelof subspaces and subsets, and investigate some of their properties. it was proved that a pairwise weakly lindelof property is not a hereditary property.

By introducing the concepts of order almost Dunford-Pettis and almost weakly limited operators in Banach lattices, we give some properties of them related to some well known classes of operators, such as, order weakly compact, order Dunford-Pettis, weak and almost Dunford- Pettis and weakly limited operators. Then, we characterize Banach lat- tices E and F on which each operator from E into F t...

in this paper, we introduce a class of $j$-quasipolar rings. let $r$ be a ring with identity. an element $a$ of a ring $r$ is called {it weakly $j$-quasipolar} if there exists $p^2 = pin comm^2(a)$ such that $a + p$ or $a-p$ are contained in $j(r)$ and the ring $r$ is called {it weakly $j$-quasipolar} if every element of $r$ is weakly $j$-quasipolar. we give many characterizations and investiga...

We report the experimental observation of periodic switching topological edge states between two dimerized fs-laser written waveguide arrays. Switching occurs due to overlap modal fields from forbidden gap, when they are simultaneously present in arrays brought into close proximity. found that phenomenon for both strongly and weakly localized rate increases with decreasing spacing When contact ...

background: corn silk (cs) is widely used in iranian traditional medicine and feijoa sellowiana(fs) is a native plant widespread in the southern parts of iran. the aim of the present study was to assess renal protective activities of cs and fs against dosage induced injury by ecstasy (mdma) using insitu rat renal perfusion (irrp) system.methods: hydro-alcoholic extract of cs and fs (10, 20, 40 ...

background: prepubertal varicocele has the most devastating effects on the testes. oxidative stress is the major cause leading to infertility in varicocele. the antioxidant properties of flaxseed (fs) treatment in some oxidative diseases have been reported. objective: this study aimed to evaluate the antioxidant effect of fs in prepubertal rats with experimental varicocele. materials and method...
