Finite-Dimensional Attractors For A General Class Of Nonautonomous Wave Equations
(Pergamon-Elsevier Science Ltd, 2000)Our aim in this note is to construct attractors and exponential attractors for a general class of nonautonomous semilinear wave equations. Following the approach described in [1], we define a semigroup S(t) associated to ... -
Defining The K(Th) Powers Of The Dirac-Delta Distribution For Negative Integers
(Pergamon-Elsevier Science Ltd, 2001)In [1], Koh and Kuan defined the powers of the Dirac-delta distribution for positive integers. Here we extend their definition for negative integers. Also, we give meaning to the distribution delta (-kappa)(+). (C) 2001 ... -
Asymptotic Behaviour of a Class of Nonlinear Functional Differential Equations of Third Order
(Pergamon-Elsevier Science Ltd, 2001)This paper deals with nonoscillatory behaviour of solutions of third-order nonlinear functional differential equations of the form y''' + p(t)y' + q(t)F(y(g(t))) = 0. It has been shown that under certain conditions on ... -

Upper Branch Nonstationary Modes Of The Boundary Layer Due To A Rotating Disk
(Pergamon-Elsevier Science Ltd, 2001)A treatment of asymptotic calculation of upper branch nonstationary instsability modes is undertaken in the boundary layer flow due to a. rotating disk. A numerical spectral solution of the eigenvalue problem shows good ... -
Spatial Behavior Estimates For The Wave Equation Under Nonlinear Boundary Conditions
(Pergamon-Elsevier Science Ltd, 2001)Our aim is to establish a spatial decay and growth estimates for solutions of the initial-boundary value problem for the linear wave equation with the damping term under nonlinear boundary conditions. (C) 2001 Elsevier ... -
A Novel Two-Enzyme Amperometric Electrode For Lactose Determination
(Japan Soc Analytical Chemistry, 2002)Coimmobilization of beta-galactosidase and glucose oxidase in a redox polymer, polyvinylferrocenium perchlorate (PVF+ClO4-), led to the development of an enzyme electrode for the determination of lactose. The amperometric ... -
Semiregular Modules With Respect To A Fully Invariant Submodule
(Marcel Dekker Inc, 2004)Let M be a left R-module and F a submodule of M for any ring R. We call M F-semiregular if for every x is an element of M, there exists a decomposition M = A circle plus B such that A is projective, A less than or equal ... -

Interval Criteria for Oscillation of Second-Order Functional Differential Equations
(Pergamon-Elsevier Science Ltd, 2005)By using averaging functions, new interval oscillation criteria are established for the second-order functional differential equation, (r (t) vertical bar x' (t)vertical bar(alpha-1) x' (t))' + F (t, x (t), x (tau (t)), ... -
Existence Of A Global Attractor For The Plate Equation With A Critical Exponent In An Unbounded Domain
(Pergamon-Elsevier Science Ltd, 2005)In this work, we study the asymptotic behavior of solutions for the plate equation with a critical exponent in R-n. We prove the existence of a global attractor in W-2(2)(R-n) x L-2(R-n). (c) 2005 Elsevier Ltd. All rights ... -
Antimicrobial Activities of Some Bacillus Spp. Strains Isolated From The Soil
(Elsevier Gmbh, Urban & Fischer Verlag, 2006)In this study a total of 29 Bacillus species isolated from the soil was analyzed using the agar diffusion method in terms of their general, inhibition effects to some test bacteria. It has been found that isolates are ... -
Asymptotic Calculation of Inviscidly Absolutely Unstable Modes of the Compressible Boundary Layer on a Rotating Disk
(Pergamon-Elsevier Science Ltd, 2006)In this work a long-wavelength asymptotic approach is used to analyze the region of absolute instability in the compressible rotating disk boundary layer flow. Theoretically determined values of branch points for the ... -

A Textural View of The Distinction Between Uniformities and Quasi-Uniformities
(Elsevier Science Bv, 2006)In this paper the authors consider the interplay between di-uniformities on a texture and a complementation on that texture. It is shown that with each di-uniformity corresponds a second di-uniformity, called its complement. ... -
Duo Modules
(Cambridge Univ Press, 2006)Let R be a ring. An R-module M is called a (weak) duo module provided every (direct summand) submodule of M is fully invariant. It is proved that if R is a commutative domain with field of fractions K then a torsion-free ...
