Study of physico-chemical properties ofdiatomiteAlgeria: Application to thethermal insulation ofliquid steel bath

Through the identification of thermal proprieties by many thermal analysis methods, we have obtained high insulting properties in high temperature up than 1400°C when the beginning

Abstract— The purpose of this paper is to characterize and to evaluate the diatomite powder of Sig region (West Algeria) without fluorine by powder generally

Both crystalline silica types (CR 1210 and CR 1212) obtained by heating diatomaceous earth, as well as the wet ground a-quartz (Qtz), gave rise to silicotic nodules and to

In Sections 2.3 and 2.4, we introduce the superpotentials mirror to a semi-Fano toric manifold written down by using toric mirror maps and Lagrangian Floer theory respectively..

A cet effet, ARITMA propose le Code de Conduite pour la Société, le Jeune et les Ecoles pour faire renaitre cette société de Paix, de Travail et travailleurs qui honorent la Patrie

We investi- gate mainly similar relations between Arnoux-Rauzy sequences and rotations of T 2 , between codings of Z 2 -actions on T 1 and multidimensional Sturmian sequences,

The unitary maps ϕ 12 will be very useful in the study of the diagonal action of U(2) on triples of Lagrangian subspaces of C 2 (see section 3).. 2.4

More precisely, he says the following: there exists non-real eigenvalues of singular indefinite Sturm-Liouville operators accumulate to the real axis whenever the eigenvalues of
