A Generalization of Projective Covers
(Academic Press Inc Elsevier Science, 2008)Let M be a left module over a ring R and I an ideal of R. We call (P, f) a projective I-cover of M if f is an epimorphism from P to M, P is projective, Ker f subset of I P, and whenever P = Ker f + X, then there exists a ... -
An Alternative Perspective on Injectivity of Modules
(Academic Press Inc Elsevier Science, 2011)Given modules M and N, M is said to be N-subinjective if for every extension K of N and every homomorphism : N M there exists a homomorphism phi : K -> M such that phi vertical bar N = phi. For a module M, the subinjectivity ... -
An Extension of the Incomplete Beta Function For Negative Integers
(Academic Press Inc Elsevier Science, 2008)The incomplete beta function B-x(a, b) is defined for a, b > 0 and 0 < x < 1. Its definition can be extended, by regularization, to negative non-integer values of a and b. In this paper we define the incomplete beta function ... -
Existence Of A Global Attractor For The Parabolic Equation With Nonlinear Laplacian Principal Part In An Unbounded Domain

Global Attractors For The Plate Equation With A Localized Damping And A Critical Exponent In An Unbounded Domain
(Academic Press Inc Elsevier Science, 2006)In this paper, we study the asymptotic behavior of solutions for the plate equation with a localized damping and a critical exponent. We prove the existence, regularity and finite dimensionality of a global attractor in ... -
Global Attractors For Von Karman Equations With Nonlinear Interior Dissipation
(Academic Press Inc Elsevier Science, 2006)In this paper we study the asymptotic behavior of weak solutions for von Karman equations with nonlinear interior dissipation. We prove the existence of a global attractor in the space W-2(2)(Omega) X L-2(Omega). (c) 2005 ... -
Global Attractors For Wave Equations With Nonlinear Interior Damping And Critical Exponents
(Academic Press Inc Elsevier Science, 2006)In this paper we study the global attractors for wave equations with nonlinear interior damping. We prove the existence, regularity and finite dimensionality of the global attractors without assuming a large value for the ... -
On Artinian Rings With Restricted Class Of Injectivity Domains
(Academic Press Inc Elsevier Science, 2013)In a recent paper of Alahmadi, Alkan and Lopez-Permouth, a ring R is defined to have no (simple) middle class if the injectivity domain of any (simple) R-module is the smallest or largest possible. Er, Lopez-Permouth and ... -
On Powers Of The Heaviside Function For Negative Integers
(Academic Press Inc Elsevier Science, 2007)The distributions (x(+)(r))(-s) and (x(+)(r))_(-s) were defined as the neutrix limit of the sequences ((x(+)(r))(-s))n and ((x(+)(r))_(-s))n respectively for r, s = 1, 2,..., see [J.D. Nicholos, B. Fisher, The distribution ... -
Rings Whose Pure-Injective Right Modules Are Direct Sums of Lifting Modules
(Academic Press Inc Elsevier Science, 2013)It is shown that every pure-injective right module over a ring R is a direct sum of lifting modules if and only if R is a ring of finite representation type and right local type. In particular, we deduce that every left ... -
Smooth Attractors Of Finite Dimension For Von Karman Evolutions With Nonlinear Frictional Damping Localized In A Boundary Layer
(Academic Press Inc Elsevier Science, 2013)In this paper dynamic von Karman equations with localized interior damping supported in a boundary collar are considered. Hadamard well-posedness for von Karman plates with various types of nonlinear damping are well known, ... -
Strongly Damped Wave Equation With Exponential Nonlinearities
(Academic Press Inc Elsevier Science, 2014)In this paper, we study the initial boundary value problem for two-dimensional strongly damped wave equation with exponentially growing source and damping terms. We first show the well-posedness of this problem and then ... -
Unliganded Estrogen Receptor-Alpha Activates Transcription Of The Mammary Gland Na+/I- Symporter Gene
(Academic Press Inc Elsevier Science, 2006)The function of sodium iodide symporter (Na+/I- symporter, or NIS) in mammary epithelial cells is essential for the accumulation of I- in milk; the newborn's first source of I- for thyroid hormone synthesis. Furthermore ...
