Refractory die-investing technique: the tendencies of setting expansion on die-investments in the process of constructing working models.
Die-pattern technique is presently the most prevalent in use as a general method of constructing inlays, and crown and bridge work. A wax pattern is prepared on a stone die and taken out to be invested and cast. This method and process of taking wax patterns out of the die occasionally causes deformation or damage to patterns due to handling or the properties of the wax itself, and this affects...

15 صفحه اولStudy on the new graph constructed by a commutative ring
Let R be a commutative ring and G(R) be a graph with vertices as proper andnon-trivial ideals of R. Two distinct vertices I and J are said to be adjacentif and only if I + J = R. In this paper we study a graph constructed froma subgraph G(R)Δ(R) of G(R) which consists of all ideals I of R such thatI Δ J(R), where J(R) denotes the Jacobson radical of R. In this paper westudy about the relation b...
