Ideal Pure Shear Strength of Aluminum and Copper
Science, 2002Although aluminum has a smaller modulus in {111}〈112̄〉 shear than that of copper, we find by first-principles calculation that its ideal shear strength is larger because of a more extended deformation range before softening. This fundamental behavior, along with an abnormally high intrinsic stacking fault energy and a different orientation dependence ...

The Pure-Science Ideal and Democratic Culture
Science, 1967These early experiences of pure scientists will have an unmistakable ring of familiarity to anyone familiar with the current situation. Charles Sanders Peirce, with characteristic insight, had stated the fundamental dilemma of the pure scientist operating within a democratic framework. How can one ask the public to provide support, much less facilities,

Normal hyperlattices and pure ideals of hyperlattices
Asian-European Journal of Mathematics, 2016Two main goals are achieved in this article. On the one hand, we introduce the notion of pure ideal in hyperlattices and provide both algebraic and topological characterizations of the notion. On the other hand, we introduce normal hyperlattices, as a natural generalization of normal lattices as treated by Cornish.

Rings in Which the Annihilator of an Ideal Is Pure
Algebra Colloquium, 2015A ring R is a left AIP-ring if the left annihilator of any ideal of R is pure as a left ideal. Equivalently, R is a left AIP-ring if R modulo the left annihilator of any ideal is flat. This class of rings includes both right PP-rings and right p.q.-Baer rings (and hence the biregular rings) and is closed under direct products and forming upper ...

In this thesis, we de ne and characterize right pure ideals, left pure ideals, right weakly pure ideals and left weakly pure ideals in T-semirings. We also characterize right weakly regular T-semirings by the properties of right pure ideals. Next, we introduce purely prime, purely semiprime, purely irreducible, strongly irreducible pure and purely ...

When every pure ideal is projective
Journal of Algebra and Its Applications, 2015In this paper, we study the class of rings in which every pure ideal is projective. We refer to rings with this property as PIP-rings. Some properties and examples of PIP-rings are given. When R is a PIP-ring, some new homological dimensions for complexes are given.

Characterising bases of pure difference ideals
2020In this thesis, we study the basis sets of pure difference ideals, that is, ideals that are generated by differences of monic monomials. We examine the action of the hyperoctahedral group on the defining ideal of the Segre variety in the multi-dimensional case and present some striking computational results.
