in this paper, some categorical properties of the category ${bf cpo}_{{bf act}text{-}s}$ of all {cpo $s$-acts}, cpo's equipped with actions of a monoid $s$ on them, and strict continuous action-preserving maps between them is considered. in particular, we describe products and coproducts in this category, and consider monomorphisms and epimorphisms. also, we show that the forgetful functor from...

this paper is a slightly revised version of an introduction into singularity theory corresponding to a series of lectures given at the ``advanced school and conference on homological and geometrical methods in representation theory'' at the international centre for theoretical physics (ictp), miramare - trieste, italy, 11-29 january 2010. we show how to associate to a triple of positive integer...

Rosa damascena has been found to act on central nervous system including the brain. Several studies confirm that R. damascena inhibits the activity of the hypothalamus and pituitary systems in rat and can suppress the central nervous system. In traditional medicine hypnotic effect of Rose is also suggested. In this study, the hypnotic effect of the ethanol crude extract of R. damascena and its ...

a review of the publications in traditional medicine indicates that the root of glycyrrhiza glabra l., fabaceae, is recommended for treatment of epilepsy. as a renewable source, the leaves of g. glabra var. glandulifera growing in iran were examined for possible anticonvulsant activity. the anticonvulsant activity of the leaves’ ethanol extract and dichloromethane, f1, n-hexane, f1a, and methan...

in an attempt to develop alternative medicine for the treatment of diabetes and related complications, the antidiabetic potential of the fruits of c rataegus pinnatifida was evaluated. the antidiabetic potential of the methanol (meoh) extract as well as different solvent soluble fractions of the fruits of c . pinnatifida was evaluated via α-glucosidase, protein tyrosine phosphatase 1b (ptp1b), ...

The purpose this research develop that valid, practical, effective in increasing knowledge and by using (Research iDevelopment). Research Development uses ADDIE model. des...

The closed model category of exterior spaces, that contains the proper category, is a useful tool for the study of non compact spaces and manifolds. The notion of exterior weak N-Sequivalences is given by exterior maps which induce isomorphisms on the k-th N-exterior homotopy groups πN k for k ∈ S, where S is a set of non negative integers. The category of exterior spaces with a base ray locali...
