in the present paper‎, ‎we show the existence of a coupled fixed point for a non-decreasing mapping in partially ordered complete metric space using a partial order induced by an appropriate function $phi$‎. ‎we also define the concept of weakly related mappings on an ordered space‎. ‎moreover common coupled fixed points for two and three weakly related mappings are also proved in the same space‎.

let $a$ be a $c^*$-algebra and $e$ be a left hilbert $a$-module. in this paper we define a product on $e$ that making it into a banach algebra and show that under the certain conditions $e$  is arens regular. we also study the relationship between derivations of $a$ and $e$.

Our research reflects an emerging shift in understandings of effective preparedness practices from siloed approaches toward more holistic views. We trace a shifting perspective emerging in literature and present in the early qualitative data of current preparedness experts’ interviews within an international humanitarian organization whose core mission is disaster preparedness and response. Des...

Almost multiplier is rather a new concept in the theory of almost functions. In this paper we discussion the boundedness of almost multipliers on some special Banach algebras, namely stable algebras. We also define an adjoint and extension for almost multiplier.

Disasters cause an acute deterioration in all stages of life. An area affected by the disaster in which the normal activities of life are disrupted is described as a "Field" in disaster terminology. Although it is not easy to define the borders of this zone, the area where there is normally functioning society is accepted as the boundary. Disaster management is the responsibility of the local g...

conclusions according to the findings of the present study, more attention should be paid to the mission and vision of the organizations in disaster preparedness. to improve the disaster preparedness measures, more emphasis should be placed on other disaster preparedness strategies such as response mechanisms and information systems. methods this was a qualitative research, which utilized conte...
