Temperature effect on the structural ferroelectric – paraelectric transition in Li2Ge7O15
(Taylor & Francis, 2016)Li2Ge7O15 (LGO) undergoes the ferroelectric – paraelectric transition at Tc D283.5K. The crystal structure of LGO is orthorhombic with the four formula units in the unit cell in the paraelectric phase (T < TC) . The ... 
Calculation of the softmode frequency for the alpha – beta transition in quartz
(Elsevier, 2016)The ? – ß structural transition occurs in quartz at TC = 846 K. The frequency of the soft mode associated with the volume increase, decreases with increasing temperature as the transition temperature is approached. In this ... 
Molar volume calculated at various pressures and the Pippard relations close to the melting point in benzene
(Taylor & Francis, 2016)The molar volume of solid and liquid benzene was calculated at various pressures (at constant temperatures), and the Pippard relations were examined close to the melting point in this organic molecule. The molar volume ... 
Pippard relation close to the alpha  beta transition for quartz in granite
(American Institute of Physics, 2016)In this study, we examine variation of the thermal expansion ?p with the isothermal compressibility KT at various temperatures (1 atm) close to the ?ß transition in quartz using the experimental data from the literature. ... 
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 cholestericsmectic A (Ch/SA) transition, as observed experimentally. We study here the thermodynamic properties of this liquid crystal ... 
The spaces of bilinear multipliers of weighted Lorentz type modulation spaces
(De Gruyter, 2016)Fix a nonzero window g?S(Rn), a weight function w on R2n and 1?p,q??. The weighted Lorentz type modulation space M(p,q,w)(Rn) consists of all tempered distributions f?S'(Rn) such that the short time Fourier transform Vgf ... 
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 boronlike Ne
(The American Astronomical Society, 2013)Recombination of Ne5+ was measured in a mergedbeam type experiment at the heavyion storage ring CRYRING. In the collision energy range 0–110 eV resonances due to 2s22p › 2s2p2 (?n = 0) and 2s22p › 2s23l (?n = 1), core ...

Highorder 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, ...
