On a new generalization of Fibonacci quaternions
(Pergamon-Elsevier Science Ltd, 2016)In this paper, we present a new generalization of the Fibonacci quaternions that are emerged as a generalization of the best known quaternions in the literature, such as classical Fibonacci quaternions, Pell quaternions, ... -
On the Durrmeyer type modification of the q-Baskakov type operators
(Pergamon-Elsevier Science Ltd, 2010)This paper deals with Durrmeyer type generalization of q-Baskakov type operators using the concept of q-integral, which introduces a new sequence of positive q-integral operators. We show that this sequence is an approximation ... -
On the q analogue of Stancu-Beta operators
(Pergamon-Elsevier Science Ltd, 2012)In the present work we introduce the q analogue of well known Stancu-Beta operators. We estimate moments and establish direct results in terms of the modulus of continuity. We also present an asymptotic formula. (C) 2011 ... -
One step effective removal of Congo Red in chitosan nanoparticles by encapsulation
(Pergamon-Elsevier Science Ltd, 2017)Chitosan nanoparticles (CNPs) were prepared with ionotropic gelation between chitosan and tripolyphosphate for the removal of Congo Red. The production of chitosan nanoparticles and the dye removal process was carried out ... -
Position vectors of a timelike and a null helix in Minkowski 3-space
(Pergamon-Elsevier Science Ltd, 2008)In this paper, we study the position vectors of a timelike and a null helix (or a W-curve), i.e. curve with constant curvatures in the Minkowski 3-space E-1(3). We give some characterizations for timelike and null helix ... -
Pre-equilibrium neutron-emission spectra of U-238 with an effective nucleon-nucleon interactions
(Pergamon-Elsevier Science Ltd, 2013)In this study, the initial exciton numbers for the target nucleus U-238 were calculated through a new method offered by Tel et al. (Ann. Nucl. Energy, 35, 220, 2008). Neutron-emission spectra produced by (n,xn) reactions ... -
Procion Brown MX-5BR attached and Lewis metals ion-immobilized poly(hydroxyethyl methacrylate)/chitosan IPNs membranes: Their lysozyme adsorption equilibria and kinetics characterization
(Pergamon-Elsevier Science Ltd, 2002)Interpenetration networks (IPNs) in membrane form were synthesized from 2-hydroxyethyl methacrylate (HEMA) and chitosan (pHEMA/chitosan) via UV-initiated photo-polymerization in the presence of an initiator alpha, ... -
Radiation effect on polyadenylic acid in aqueous solution
(Pergamon-Elsevier Science Ltd, 1995)In this study, dilute solution properties of polyadenylic acid (polyA), G values for single strand break formation G(ssb), Arrhenius parameters (25-45 degrees C), the kinetics of strand break in the absence and presence ... -
Study of the pre-equilibrium mean free path constant for light and heavy nuclei for (n, xn) reactions
(Pergamon-Elsevier Science Ltd, 2011)Using pre-equilibrium reaction mechanisms, the neutron-emission spectra produced by (n, xn) reactions for some target (A = 16 similar to 238) nuclei have been calculated for incident neutron energy in the range of 15-26 ... -
Wastewater treatment at the petroleum refinery, Kirikkale, Turkey using some coagulants and Turkish clays as coagulant aids
(Pergamon-Elsevier Science Ltd, 1998)In this study, waste water of Kirikkale Refinery (Turkey) was treated with coagulants (alum, ferric chloride, ferrous sulfate and lime) and coagulant aids (polyelectrolytes: anionic, cationic, nonionic) and some Turkish ...
