In this paper, we introduce the notion of $M$-fuzzifying interval spaces, and discuss the relationship between $M$-fuzzifying interval spaces and $M$-fuzzifying convex structures.It is proved that the category {bf MYCSA2} can be embedded in the category {bf MYIS} as a reflective subcategory, where {bf MYCSA2} and {bf MYIS} denote the category of $M$-fuzzifying convex structures of...
nepeta satureioides boiss. has been used in traditional medicine of eastern countries and is famous for its medicinal properties. the aim of this study was to evaluate the effect of methanol (meoh), n -hexane and dichloromethane (ch 2 cl 2 ) fractions of the extract on melanin synthesis and oxidative stress in b16f10 melanoma cell line. the b16f10 cell line viability after treatment with increa...
we give the concept of ‘braiding’ for 2-groupoids, and we show that this structure is equivalent tobraided regular, crossed modules.
In this paper, the concepts of $L$-concave structures, concave $L$-interior operators and concave $L$-neighborhood systems are introduced. It is shown that the category of $L$-concave spaces and the category of concave $L$-interior spaces are isomorphic, and they are both isomorphic to the category of concave $L$-neighborhood systems whenever $L$ is a completely distributive lattice. Also, it i...

Introduction: Infectious diseases, mainly caused by bacterial agents, are one of the most common causes of death worldwide. A significant number of these agents have been resistant to one or more antibiotics; some of them are multi-drug resistant and others are extensively drug resistant. Various antimicrobial and anticancer compounds have been reported from the venom of various species of scor...
An object $X$ of a category $mathbf{C}$ with finite limits is called exponentiable if the functor $-times X:mathbf{C}rightarrow mathbf{C}$ has a right adjoint. There are many characterizations of the exponentiable spaces in the category $mathbf{Top}$ of topological spaces. Here, we study the exponentiable objects in the category $mathbf{STop}$ of soft topological spaces which is a generalizati...
“ba:y?d” as a persian lexeme is interwoven with modality, a semantic category and therefore has a complicated and thought- provoking semantic nature. this paper uses evidence from persian to investigate the usage of this lexeme and some of its semantic and pragmatic aspects in this language. the results indicate that this lexical category can convey a wide range of modal meanings in different c...
