Some properties of the generalized Fibonacci and Lucas sequences related to the extended Hecke groups
(Springer, 2013)In this paper, we define a sequence, which is a generalized version of the Lucas sequence, similar to the generalized Fibonacci sequence given in Koruo. glu and, Sahin in Turk. J. Math. 2009, doi:10.3906/mat-0902-33. Also, ... -
On the images of ellipses under similarities
(Ovidius Univ Press, 2013)We consider ellipses corresponding to any norm function on the complex plane and determine their images under the similarities which are special Mobius transformations. -

Spatial-temporal variations of sulphur dioxide concentration, source, and probability assessment using a GIS-based geostatistical approach
(Hard, 2013)Ground-level sulphur dioxide is one of the air pollutants of high concern as a typical indicator of urban air quality. To inform decisions regarding, for instance, the protection of public health from elevated SO2 levels ... -
Investigation of B-x and B-y components of the magnetic flux leakage in ferromagnetic laminated sample
(Hindawi Publishing Corp, 2013)The magnetic flux leakage (MFL) technique is most commonly used for crack detection from iron bars, laminated sheets, and steel tubes of ferromagnetic nature. Magnetic flux leakage system induces a magnetic field and detects ... -
Removal of an anionic dye from aqueous solution by sepiolite using a full factorial experimental design
(Parlar Scientific Publications (P S P), 2013)Optimization of parameters by the classical batch adsorption method involves changing one independent variable and keeping the other factors constant in the same time. Classical method investigating effect of one variable ... -
Squares of congruence subgroups of the extended modular group
(Univ Miskolc Inst Math, 2013)In this paper, we generalize some results related to the congruence subgroups of modular group Gamma, given in [7] and [6] by Kiming, Schutt, and Verrill, to the extended modular group Pi. -
Genome-wide identification of alternate bearing-associated microRNAs (miRNAs) in olive (Olea europaea L.)
(BMC, 2013)Background: Alternate bearing is a widespread phenomenon among crop plants, defined as the tendency of certain fruit trees to produce a high-yield crop one year ("on-year"), followed by a low-yield or even no crop the ... -
The total incoherent scattering cross sections for low-Z elements
(Pergamon-Elsevier Science Ltd, 2013)The total incoherent scattering cross sections are calculated using relativistic and nonrelativistic incoherent scattering functions for the energy range 1-10,000 keV for low-Z elements (C, O, Ne, S, Ar). The calculated ... -
Element fractionation analysis for milk in its real matrix by inductively coupled plasma optical emission spectrometry
(Taylor & Francis Ltd, 2013)Fractionation of elements in food is essential for understanding and prediction of its bioavailability, effects, and toxicity. In the present study, an analytical fractionation scheme for milk samples was developed for the ... -
Chen inequalities for submanifolds of a Riemannian manifold of nearly quasi-constant curvature
(Kossuth Lajos Tudomanyegyetem, 2013)The object of the present paper is to study Chen first inequality and k-Ricci curvatures for submanifolds of a Riemannian manifold of nearly quasi-constant curvature. -
