background: prediction of interaction sites within the membrane protein complexes using the sequence data is of a great importance, because it would find applications in modification of molecules transport through membrane, signaling pathways and drug targets of many diseases. nevertheless, it has gained little attention from the protein structural bioinformatics community. methods: in this stu...

in this work we deal with actions of vector groupoid which is a new concept in the literature‎. ‎after we give the definition of the action of a vector groupoid on a vector space‎, ‎we obtain some results related to actions of vector groupoids‎. ‎we also apply some characterizations of the category and groupoid theory to vector groupoids‎. ‎as the second part of the work‎, ‎we define the notion...

In the present paper, we introduce and study a fuzzy vector equilibrium problem and prove some existence results with and without convexity assumptions by using some particular forms of results of textit{Kim} and textit{Lee} [W.K. Kim and K.H. Lee, Generalized fuzzy games and fuzzy equilibria, Fuzzy Sets and Systems, 122 (2001), 293-301] and textit{Tarafdar} [E. Tarafdar, Fixed point theorems i...

background: human malaria remains a major malady in eastern iran. vector control interventions such as indoor residual spraying are used to fight with the disease. this study was undertaken to determine the lethal and residual effects of three different pyrethroid insecticides on adult mosquitoes of anopheles stephensi on different surfaces in iran, as part of a national program to monitor inse...

background and aims: adenovector gene transfer induces inflammatory response that finally leads to vector removal from delivered site. the effect of hydrodynamic pre-injection on adenovector mediated liver inflammation remained elusive. materials and methods: different mice groups were pre-treated by hydrodynamic saline, dexamethasone or nothing prior to adeno-luciferase administration. their s...

cockroaches were collected from hospitals, houses and poultry sheds in various parts of isfahan (iran) and identified to species. in total, seven species of cockroaches in seven genera were identified: blatta lateralis, polyphaga aegyptiaca, arenivaga roseni and parcoblatta spp. three species periplaneta americana, blattella germanica and supella longipalpa (blattidae and blattellidae) were mor...

b a ckground: diagnostic study of vector ticks for different pathogens transmitted specifically have been done by iranian old scientists working on the basis of biological transmission of pathogens. in this study we decided to con- firm natural infection of different collected ticks from three different provinces of iran. m e t hods: ticks were collected from livestock (sheep, goats and cattle)...

‎In this paper‎, ‎we introduce and study a class of generalized vector quasi-equilibrium problem‎, ‎which includes many vector equilibrium problems‎, ‎equilibrium problems‎, ‎vector variational inequalities and variational inequalities as special cases‎. ‎Using one person game theorems‎, ‎the concept of escaping sequences and without convexity assumptions‎, ‎we prove some existence results for ...

In the first part of this paper, some theorems are given for a Riemannian manifold with semi-symmetric metric connection. In the second part of it, some special vector fields, for example, torse-forming vector fields, recurrent vector fields and concurrent vector fields are examined in this manifold. We obtain some properties of this manifold having the vectors mentioned above.
