In this article, we analyze the emergence of a global security norm COVID-19 epidemic as threat to international security. This crisis is one gravest crises that humanity has experienced since end World War II in terms number people infected and died, but also economic consequences. Here, provide framework for understanding securitization an defined promoted by Health Organization entrepreneur,...

We introduce Banach algebras arising from tensor norms. By these Banach algebras we make Arensregular Banach algebras such that tensor product becomes irregular, where is tensor norm. Weillustrate injective tensor product, does not preserve bounded approximate identity and it is notalgebra norm.

organic farming as an approach to sustainable agriculture tries to decrease environmental problems and possible health hazards caused by the residues from pesticides. since the agricultural professionals are responsible to inform the farmers and the public by education and extension efforts, it is necessary to understand their attitudes. the main purpose of this research was to investigate fact...

Fuzzy best simultaneous approximation of a finite number of functions is considered. For this purpose, a fuzzy norm on $Cleft (X, Y right )$ and its fuzzy dual space and also the  set of subgradients of a fuzzy norm are introduced. Necessary case of a proved theorem about characterization of simultaneous approximation will be extended to the fuzzy case.

the values are the frameworks to legitimize human behaviors and to conceptualize socio-cultural phenomena. normalizing human behavior values are formed through three main bases including cognitive, motivate, and arbitrary ones. therefore, the normative values would shape through cognitive, motivate, and arbitrary foundations. behavior formation and stabilization happen in the process of sociali...

in this paper, we introduce the notion of an action $y_x$as a generalization of the notion of a module,and the notion of a norm $vt: y_xto f$, where $f$ is a field and $vartriangle(xy)vartriangle(y') =$ $ vartriangle(y)vartriangle(xy')$ as well as the notion of fuzzy norm, where $vt: y_xto [0, 1]subseteq {bf r}$, with $bf r$  the set of all real numbers. a great many standard mappings on algebr...
