we study umbilic (space-like) submanifolds of pseudo-riemannian space forms, then define totally semi-umbilic space-like submanifold of pseudo euclidean space and relate this notion to umbilicity. finally we give characterization of total semi-umbilicity for space-like submanifolds contained in pseudo sphere or pseudo hyperbolic space or the light cone.a pseudo-riemannian submanifold m in (a ps...

The aim of this paper is to introduce the notion of commutative pseudo BE-algebras and investigate their properties.We generalize some results proved by A. Walendziak for the case of commutative BE-algebras.We prove that the class of commutative pseudo BE-algebras is equivalent to the class of commutative pseudo BCK-algebras. Based on this result, all results holding for commutative pseudo BCK-...

Adsorption Kinetics describes the rate at which solute is adsorbed and resident time of adsorbates on solid-liquid interface. isotherms play important role in determining interaction between adsorbate adsorbent optimum adsorption capacity adsorbent. This article considered selected kinetics models. Pseudo first order, second Elovich, Bhattacharya Venkobachar, Natarajan Khalaf were reviewed assu...

The problem of the development underground erosion is considered ion article. most brightly shown in massifs loessial breeds, which are widely developed Uzbekistan. This phenomenon consequences described science as term “loessial pseudo-karst”. pseudo-karst have received greatest spread and places an active technogenesis since second half XX century. Besides territories connected with civil, in...

Os autores fazem o relato de três casos clínicos: Papilomatose florida, Epitelioma cuniculatum e Condiloma gigante Buschke Lowenstein, considerados como representativos entidades que compõem grupo das Papilomatoses pseudo-carcinomatosas. São favoráveis à conceituação pseudo-carcinomatosas apoiando-se na semelhança clínica, histopatológica, evolutiva da terapêutica a ser instituída. Discutem, ai...

In this paper, we study the theory of pseudo knots, which are knots with some missing crossing information, and introduce tied links knotoids. particular, first present a braiding algorithm for then L-moves in that setting, use formulate sharpened version analogue Markov theorem braids. Then, links, generalize notion exploit relation between singular links. We an L-move braid equivalence monoid...
