Analysis of the thermal expansivity near the tricritical point in dilute chromium alloys
(American Institute of Physics, 2016)Chromium (Cr) undergoes a first order Neel transition as an antiferromagnetic material. When V, Mo and Mn atoms are substituted in the Cr lattice, a weak first order Neel transition in pure Cr changes toward a second order ... -
Variation of the molar volume with the temperature and the Pippard relations near the melting point in benzene
(Elsevier, 2016)In this study, we calculate variation of the molar volume with the temperature at constant pressures (70.5, 85.2, 128 and 175.2 MPa) using the experimental data from the literature for the solid and liquid phases of benzene ... -
Pressure effect on the cholesteric – smectic A transition in cholestryl myristate
(Taylor & Francis, 2016)Cholesteryl myristate exhibits tricritical behavior under high pressures close to its cholesteric-smectic A (Ch/SA) transition, as observed experimentally. We study here the thermodynamic properties of this liquid crystal ... -
Calculation of the Raman frequency shifts for the ? phase of solid oxygen
(Elsevier, 2017)We calculate in this study the Raman frequencies of the two librons and one vibron at various pressures at constant temperatures of 10 K and also at the temperatures of 6 and 18 K by using the volume data from the literature ... -
The Amalgam spaces W(Lp(x),{pn} ) and boundedness of hardy–littlewood maximal operators
(Springer, 2015)Let Lq(x)(R)Lq(x)(R) be variable exponent Lebesgue space and l{qn}l{qn} be discrete analog of this space. In this work we define the amalgam spaces W(L p(x),L q(x)) and W(Lp(x),l{qn})W(Lp(x),l{qn}), and discuss some basic ... -
Stress analysis of ceramic insulation coating on Cu/MgB2 wires for W&R MgB2 coils
(Elsevier, 2009)Ceramic insulation coatings were produced on Cu/MgB2 wires, which were fabricated by Hyper Tech Research Inc., using Continuous Tube Forming and Filling (CTFF) process, from the solution of Zr, and Y based organometalic ... -
Recombination rate coefficients of boron-like Ne
(The American Astronomical Society, 2013)Recombination of Ne5+ was measured in a merged-beam type experiment at the heavy-ion storage ring CRYRING. In the collision energy range 0–110 eV resonances due to 2s22p › 2s2p2 (?n = 0) and 2s22p › 2s23l (?n = 1), core ... -
Raman frequencies calculated at various pressures in phase I of benzene
(KCS Publications, 2013)We calculate in this study the pressure dependence of the frequencies for the Raman modes of A (Ag), B (Ag, B2g) and C (B1g, B3g) at constant temperatures of 274 and 294K (room temperature) for the solid phase I of benzene. ... -
Phase-dependent interference fringes in the wavelenght scaling of harmonic efficiency
(American Physical Society, 2014)We describe phase-dependent wavelength scaling of high-order harmonic generation efficiency driven by ultra-short laser fields in the mid-infrared. We employ both numerical solution of the time-dependent Schr¨odinger ... -
On the weighted variable exponent amalgam space W(L-P(X) , L-M(Q))
(Elsevier, 2014)In [4], a new family W(L-p(x), L-m(q))of Wiener amalgam spaces was defined and investigated some properties of these spaces, where local component is a variable exponent Lebesgue space L-p(x) (R) and the global component ... -
Thermochemistry of N-heterocyclic carbenes with 5-, 4-, 3-, and 2-membered rings
(Wiley, 2014)N-heterocyclic carbenes (NHCs) based on imidazole-2-ylidene (1) or the saturated imidazolidine-2-ylidene (2) scaffolds are long-lived singlet carbenes. Both benefit from inductive stabilization of the sigma lone pair on ... -

(Elsevier, 2014)We prove that the outer automorphism group of a free group of countably infinite rank is complete. -
High-order harmonic generation from Rydberg states at fixed Keldysh parameter
(Institute for Scientific Information, 2013)Because the commonly adopted viewpoint that the Keldysh parameter ? determines the dynamical regime in strong field physics has long been demonstrated to be misleading, one can ask what happens as relevant physical parameters, ... -

A note on the order bidual of f-algebras
(Hikari, 2013)The paper deals with the Arens Multiplication which we accomplished in four steps in the order bidual ~ ~ X . It is shown that if f is an element of order dual ~ X of X with ? ( f )?0 and , + x ? X then f .x = 0 implies f (x)= . -
