Garside calculus is the common mechanism that underlies a certain type of normal form for the elements of a monoid, a group, or a category. Originating from Garside’s approach to Artin’s braid groups, it has been extended to more and more general contexts, the latest one being that of categories and what are called Garside families. One of the benefits of this theory is to lead to algorithms so...

some medicinal plants are a potential source of new drugs, in order to improve the treatment of chagas disease whose treatment is still a challenge. in this study, the in vitro anti-epimastigote activity of certain fractions of achillea biebersteinii, a. millefolium, satureja mutica and s. macrantha was evaluated. diethyl ether fractions of achillea species and acetone fractions of satureja spe...

aggregate stability is an important soil property because it dictates how strongly a soil can resist water erosion. the objectives in this study were: (1) to compare the stability of six soil aggregate size fractions, primarily to determine if aggregate stability varies with aggregate size, and (2) to determine with which aggregate size fraction the stability of most soils would be different fr...

objective(s) the fractions of candida albicans have been used as an immunomodulator. the present work assessed the effect of different fractions of c. albicans on nitric oxide (no) production by mice peritoneal macrophages. materials and methods cell wall and cytoplasmic fractions of c. albicans atcc 10321 strain were extracted. mice peritoneal macrophages were purified and cultured. different ...

Inthispaper, (L,M)-fuzzy domain finiteness and (L,M)-fuzzy restricted hull spaces are introduced, and several characterizations of the category (L,M)-CS of (L,M)-fuzzy convex spaces are obtained. Then, (L,M)-fuzzy stratified (resp. weakly induced, induced) convex spaces are introduced. It is proved that both categories, the category (L,M)-SCS of (L,M)-fuzzy stratified convex spaces and the cate...

this study was carried out to evaluate the antimicrobial and antioxidant effectiveness of methanolic extract and different fractions (n-butanol, ethyl acetate, chloroform and n-hexane) of c.intybus seeds. the antimicrobial activity was determined by the disc diffusion method and minimum inhibitory concentration (mic) against a panel of microorganisms (four bacterial strains, i.e. p. multocida, ...

In this paper, the concepts of derived sets and derived operators are generalized to $(L, M)$-fuzzy topological spaces and their characterizations are given.What is more, it is shown that the category of stratified $(L, M)$-fuzzy topological spaces,the category of stratified $(L, M)$-fuzzy closure spaces and the category of stratified $(L, M)$-fuzzy quasi-neighborhood spaces are all isomorphic ...

Objective(s) In the present study, the differences in the relaxant effects of aqueous, ethyl acetate and n-butanol fractions of Rosa damascena on tracheal smooth muscle of guinea pigs were examined. Materials and Methods The relaxant effects of three cumulative concentrations of each fraction (0.1, 0.2 and 0.4 g%) in comparison with saline and three cumulative concentrations of theophylline ...
