FiniteDimensional Attractors For A General Class Of Nonautonomous Wave Equations
(PergamonElsevier 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 ... 
Spatial Behavior Estimates For The Wave Equation Under Nonlinear Boundary Conditions
(PergamonElsevier Science Ltd, 2001)Our aim is to establish a spatial decay and growth estimates for solutions of the initialboundary value problem for the linear wave equation with the damping term under nonlinear boundary conditions. (C) 2001 Elsevier ... 
Defining The K(Th) Powers Of The DiracDelta Distribution For Negative Integers
(PergamonElsevier Science Ltd, 2001)In [1], Koh and Kuan defined the powers of the Diracdelta 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
(PergamonElsevier Science Ltd, 2001)This paper deals with nonoscillatory behaviour of solutions of thirdorder 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
(PergamonElsevier 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 ... 
A Novel TwoEnzyme Amperometric Electrode For Lactose Determination
(Japan Soc Analytical Chemistry, 2002)Coimmobilization of betagalactosidase 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 Rmodule and F a submodule of M for any ring R. We call M Fsemiregular 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 SecondOrder Functional Differential Equations
(PergamonElsevier Science Ltd, 2005)By using averaging functions, new interval oscillation criteria are established for the secondorder functional differential equation, (r (t) vertical bar x' (t)vertical bar(alpha1) 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

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 ... 
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 W2(2)(Omega) X L2(Omega). (c) 2005 ... 
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 ...

A Textural View of The Distinction Between Uniformities and QuasiUniformities
(Elsevier Science Bv, 2006)In this paper the authors consider the interplay between diuniformities on a texture and a complementation on that texture. It is shown that with each diuniformity corresponds a second diuniformity, called its complement. ...
