Determination of dosimetric and kinetic features of gamma irradiated solid calcium ascorbate dihydrate using ESR spectroscopy
(Taylor & Francis Inc, 2013)Effects of gamma radiation on solid calcium ascorbate dihydrate were studied using electron spin resonance (ESR) spectroscopy. Irradiated samples were found to present two specific ESR lines with shoulder at low and high ... -
Improved converse theorems and fractional moduli of smoothness in Orlicz spaces
(Malaysian Mathematical Sciences Soc, 2013)In the present work converse theorems of trigonometric approximation of functions and its fractional derivatives in certain Orlicz spaces are improved with respect to the fractional moduli of smoothness. An improved Marchaud ... -
Approximation by (C,1) and Abel-Poisson means of Fourier series on hexagonal domains
(Element, 2013)The approximation problems by Cesaro (C, 1) means and by Abel-Poisson means of Fourier series on hexagonal domains are studied. The estimates for the rate of convergence of these means are obtained for functions in Lipschitz ... -
Growth and characterizations of magnetic nanoparticles under hydrothermal conditions: Reaction time and temperature
(Elsevier Science BV, 2015)Magnetic iron oxide nanoparticles with various sizes and magnetic properties were synthesized by using a hydrothermal method. The initial nanoparticles were obtained by co-precipitation of ferric and ferrous salts and then ... -
Properties of electrodeposited CoFe/Cu multilayers: The effect of Cu layer thickness
(Elsevier Science Bv, 2015)CoFe/Cu mulfflayers were potentiostatically electrodeposiled on Ti substrates as a function of different non-magnetic (Cu) layer thicknesses, and their characterizations were investigated. The compositional analysis performed ... -
Relationships between fixed points and eigenvectors in the group GL (2, ℝ)
(Springer International Publishing Ag, 2013)PSL(2, R) is the most frequently studied subgroup of the Mobius transformations. By adding anti-automorphisms G' = {a'z + b'/c'z + d' : a', b', c', d' is an element of R, a'd' - b'c' = -1} to the group PSL(2, R), the ... -
Characterizations of FeCl/Cu superlattices sputtered at low and high deposition rates of ferromagnetic layer
(Elsevier Science Bv, 2015)FeCl/Cu superlattices was grown using a dc magnetron sputtering at low (0.02 nm/s) and high (0.08 nm/s) deposition rates of ferromagnetic layer, and the properties of the superlattices were investigated. Structural ... -
