Absolute evaluation of ferrous and ferric concentration in Ca amphibole
( WILEY-VCH Verlag , 1982 , Article)Studies are made of M?sshauer absorption of 57Fe in a Ca-amphibole schist sample at room and liquid nitrogen temperatures. The absolute concentration and the recoilless fraction for ferrous and ferric cations are determined ... -
Asymptotic formulae for eigenvalues and eigenfunctions of q-Sturm-Liouville problems
( WILEY-VCH Verlag , 2011 , Article)We investigate the asymptotic behavior of the eigenvalues and the eigenfunctions of q-Sturm-Liouville eigenvalue problems. For this aim we study the asymptotic behavior of q-trigonometric functions as well as fundamental ... -
Gamma irradiation effects on polymethyl methacrylate
( WILEY-VCH Verlag , 2007 , Article)The effect of gamma-irradiation on the structure of polymethyl methacrylate (PMMA) has been investigated. In this study, the PMMA specimens were gamma-irradiated at doses in the range of 0-1000 kGy and measured by means ... -
The Structure of the Free Volume in Poly(styrene-co-acrylonitrile) from Positron Lifetime and Pressure Volume Temperature (PVT) Experiments
( WILEY-VCH Verlag , 2004 , Article)Summary: The structure of the free volume and its temperature dependence between 25 and 190 °C of copolymers of styrene with acrylonitrile, SAN (0 to 50 mol-% AN), is studied by pressure volume temperature (PVT) experiments ...
