An Alternative Perspective on Injectivity of Modules
(Academic Press Inc Elsevier Science, 2011)Given modules M and N, M is said to be Nsubinjective 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 Analytic ShootingLike Approach For The Solution of Nonlinear Boundary Value Problems
(PergamonElsevier Science Ltd, 2011)In this paper a novel approach is presented for an analytic approximate solution of nonlinear differential equations with boundary conditions. By converting the nonlinear problem into an initial value form, a shootinglike ... 
An Asymptotic Investigation Into The Stabilization Effect Of Suction In The RotatingDisk Boundary Layer Flow
(PergamonElsevier Science Ltd, 2007)The suction effects in the threedimensional boundary layer flow due to a rotating disk are analyzed from the linear stability point of view making use of the asymptotic structure of the suction mean velocity profiles of ... 
An Extension of the Incomplete Beta Function For Negative Integers
(Academic Press Inc Elsevier Science, 2008)The incomplete beta function Bx(a, b) is defined for a, b > 0 and 0 < x < 1. Its definition can be extended, by regularization, to negative noninteger values of a and b. In this paper we define the incomplete beta function ... 
An Optimal Variational Iteration Method
(PergamonElsevier Science Ltd, 2011)The variational iteration method is studied in the present work. The classical variational iteration method is improved and extended by introducing a new concept of a convergence accelerating parameter. A rigorous approach ... 
An Unconventional Finite Difference Scheme For Modified KortewegDe Vries Equation
(Hindawi Ltd, 2017)A numerical solution of the modified Kortewegde Vries (MKdV) equation is presented by using a nonstandard finite difference (NSFD) scheme with theta method which includes the implicit Euler and a CrankNicolson type ... 
Analytic Approximate Solutions of Parameterized Unperturbed And Singularly Perturbed Boundary Value Problems
(Elsevier Science Inc, 2011)A novel approach is presented in this paper for approximate solution of parameterized unperturbed and singularly perturbed twopoint boundary value problems. The problem is first separated into a simultaneous system regarding ... 
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 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 ... 
Asymptotic Calculation of Inviscidly Absolutely Unstable Modes of the Compressible Boundary Layer on a Rotating Disk
(PergamonElsevier Science Ltd, 2006)In this work a longwavelength 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 ... 
BlowUp of Solutions to Quasilinear Parabolic Equations
(PergamonElsevier Science Ltd, 1999)Sufficient conditions for global nonexistence (blow up) of solutions of the initialboundary value problem for a class of secondorder quasilinear parabolic equations: [GRAPHICS] are established. (C) 1999 Elsevier Science ... 
Categories of Rough Sets and Textures
(Elsevier Science Bv, 2013)It is known that the theories of rough sets and fuzzy sets have successful applications in computing. Textures, as a theoretical model, provide a new perspective for both rough sets and fuzzy sets. Indeed, recent papers ... 
Completeness Types For Uniformity Theory On Textures
(Univ Nis, Fac Sci Math, 2015)In this paper the author considers the various types of completeness for diuniform texture spaces and especially for complemented ones. Following that, the relationships between completeness of uniform spaces and these ... 
Complex And Symplectic Structures On Panelled Web 4Manifolds
(Elsevier Science Bv, 2012)We analyze the symplectic and complex structures on the panelled web 4manifolds of S. Akbulut and M. Kalafat [1]. In particular, we give infinite families of examples of almost complex but not symplectic and not complex ... 
Continuous Dependence Of Solutions To FourthOrder Nonlinear Wave Equation
(Hacettepe Univ, Fac Sci, 2016)This paper gives a priori estimates and continuous dependence of the solutions to fourthorder nonlinear wave equation. 
Definability And Textures
(Elsevier Science Inc, 2012)This paper aims to give a new perspective for definability in rough set theory. First, a counterpart of definability is introduced in textural approximation spaces. Then a complete field of sets for texture spaces is defined ... 
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 ... 
DiExtremities And Totally Bounded DiUniformities
(Univ Nis, Fac Sci Math, 2018)In our previous studies, we have defined a counterpart, called a diextremity, to the classical notion proximity in the complementfree setting of a texture. In this article, we will investigate relationship between totally ...
