摘要:Psomopoulos has proved that \([x^n, y] = [x, y^{n+1}]\) for a positive integer n implies commutativity in groups. Here we show that cancellative semigroups admitting commutators and satisfying the identity \([x^n, y] = [x, y^{n+k}]\) implies that the element \(y^k\) is central. T...

摘要:Abstract(#br)A two-dimensional steady state visco-plastic model has been developed for friction stir welding of dissimilar metals using a commercial CFD code, FLUENT®. Volume of Fluid (VOF) approach is used to model the welding process of dissimilar metals. Initially, the mo...

摘要:Abstract(#br)Deep drawing is a forming process controlled by a number of parameters. The initial blank shape is one of the most important process parameter that has a direct impact on the quality of the finished part. This paper describes a new method to determine the optimal bla...

摘要:Abstract(#br)We present the first known single axioms for ternary Boolean algebra. The first single axiom was found algebraically by a previous technique of Padmanabhan and Quackenbush; then simpler single axioms were found by using the automated reasoning program Otter .

摘要:Abstract(#br)Mathematical theories of elasticity–plasticity have received considerable development in recent years. However, the quantity of accurate experimental work, carried out to examine the validity of these theories appears to be limited. As the theories have increase...

摘要:Abstract(#br)The TO mouse exhibits a low incidence (3.65%) of spontaneous exencephaly at birth. The objectives of this study were to determine if sodium valproate (VPA) would augment this background frequency of exencephaly and to characterize its gross and histologic bases. Sing...

摘要:Abstract(#br)Vigabatrin (VGB) has several therapeutic advantages over older antiepileptic drugs (AED), but there is a lack of information about its potential reproductive toxicologic effects. Our aim was to evaluate the consequences of VGB administered during late gestation on fe...

摘要:Abstract(#br)Structural members subjected to external load achieve extra strength by an initial permanent deformation. During the initial stages of elasto-plastic deformation, increasing stress is needed to cause plastic strain in the member, due to strain hardening. In practice,...

摘要:Abstract(#br)Metal matrix composite materials are designed and engineered to exhibit properties that are most desirable for a given application. The properties of the composite will depend upon the particular constituents and volume fraction used, but most MMCs show improvem...
