Irregular Boundary Value Problems with Discontinuous Coefficients and the Eigenvalue Parameter
(SPRINGER BASEL AG, 2009)
In this study, a Birkhoff-irregular boundary value problem for linear ordinary differential equations of the second order with discontinuous coefficients and the spectral parameter has been considered. Therefore, at the ...
Analytical evaluation for two-center nuclear attraction integrals over slater type orbitals by using Fourier transform method
(SPRINGER, 2009)
In this study, we shall suggest analytical expressions for two-center nuclear attraction integrals over STO's with a one-center charge distribution by using Fourier transform method. The derivation is based on partial-fraction ...

On Mannheim partner curves in E-3
(ACADEMIC JOURNALS, 2009)
The aim of this paper is to study the Mannheim partner curves in Euclidean space E-3. We obtain the relationships between the curvatures and the torsions of the Mannheim partner curves with respect to each other.
Effects of Preoperative Conventional and Hyperfractionated Radiotherapy on the Healing of Rat Colonic Anastomoses
(KARGER, 2009)
Background: One problem associated with end to end anastomoses after preoperative radiotherapy is leakage. The strength of the anastomoses is very important. Fractionation schedules are widely under investigation to achieve ...
Evaluation of the NDVI in plant community composition mapping: a case study of Tersakan Valley, Amasya County, Turkey
(TAYLOR & FRANCIS LTD, 2009)
Mapping the composition of plant community types requires reliable spatial data obtained from field surveys and satellite-derived indices. The normalized difference vegetation index (NDVI) is the simplest and most frequently ...
