On ordered domains of integrity [PDF]
Proceedings of the American Mathematical Society, 1952 In a recent paper,' T. Szele proved that a division ring D is orderable if and only if the additive and multiplicative semigroup S generated by the nonzero squares of elements of D does not contain the zero element of D. The present paper extends this result to a domain of integrity K. Let us denote by K* the set of nonzero elements of K. The domain of

On locally divided integral domains and CPI-overrings
International Journal of Mathematics and Mathematical Sciences, 1981 It is proved that an integral domain R is locally divided if and only if each CPI-extension of ℬ (in the sense of Boisen and Sheldon) is R-flat (equivalently, if and only if each CPI-extension of R is a localization of R).

Generalization to The AMK Integral Transform and Its Applications [PDF]
مجلة جامعة الانبار للعلوم الصرفةSince the proposal of Laplace to integral transformation in 1780, many integral transformations have been proposed. Some are based on Laplace, and others are totally independent.

Engineering Transactions, 2014 An initial stability of Kirchhoff plates is analysed in the paper. Proposed approach avoids Kirchhoff forces at the plate corner and equivalent shear forces at a plate boundary. Two unknown variables are considered at the boundary element node.

An integrated approach to the prediction of domain-domain interactions [PDF]
BMC Bioinformatics, 2006 Abstract Background The development of high-throughput technologies has produced several large scale protein interaction data sets for multiple species, and significant efforts have been made to analyze the data sets in order to understand protein activities.

Factor Rings with Algebraic Identities via Generalized Derivations
AxiomsThe current article focuses on studying the behavior of a ring ℜ/Π when ℜ admits generalized derivations Ψ and Ω with associated derivations ϕ and δ, respectively. These derivations satisfy specific differential identities involving Π, where Π is a prime

A new three-dimensional J-integral formulation for arbitrary load history and finite deformation
Nihon Kikai Gakkai ronbunshu, 2018 In this paper, a new formulation of three-dimensional J-integral for the evaluation of elastic-plastic fracture problem is presented. It is known that the J-integral represents the energy release rate per unit crack extension.

Prolongations of integral domains
Journal of Algebra, 1985 The motivation for this rather extensive and complicated paper is derived from the purely algebraic approach to the theory of overdetermined systems of partial differential equations. A system of (algebraic) differential equations represents a set of elements \(F_ 1,F_ 2,...,F_ n\) of a polynomial ring \(P=k[\delta^ py_ j: p\in {\mathbb{N}}^ m, j=1,...,
