#### Integral representations of the Legendre chi function

(Journal of Mathematical Analysis and Applications, 2007)

We, by making use of elementary arguments, deduce integral representations of the Legendre chi function chi(S)(z) valid for vertical bar z vertical bar LT 1 and Res GT 1. Our earlier established results on the integral ...

#### Zn-Mn-O: Ferromagnet at room temperature

(Hemijska industrija, 2007)

Semiconductor Zn-Mn-O crystallites were synthesized by a solid state reaction method starting from the thermal decomposition of the appropriate oxalates. Samples were thermally treated in air at temperatures ranging from ...

#### Dynamics of dark breathers in lattices with saturable nonlinearity

(Optics Express, 2007)

The problems of the existence, stability, and transversal motion of the discrete dark localized modes in the lattices with saturable nonlinearity are investigated analytically and numerically. The stability analysis shows ...

#### Excessive excitation of hydrogen peroxide during oscillatory chemical evolution

(Journal of Physical Chemistry. Part A: Molecules, Spectroscopy, Kinetics, Environment and General Theory, 2007)

The peculiar reaction dynamics of the Bray-Liebhafsky chemical oscillator is connected with the nonequilibrium periodic excitations of hydrogen peroxide embedded in a hydrogen-bonded water network. This was indicated by ...

#### Optimal parameterization in the measurements of the thermal diffusivity of thermal barrier coatings

(Thermal Science, 2007)

The paper presents an estimation procedure for the measurement of the thermal diffusivity of thermal barrier coatings deposited on thermal conductive substrates using the laser flash method when the thermal contact resistance ...

#### Spectral indices of Galactic radio loops between 1420, 820 and 408 MHz

(Monthly Notices of the Royal Astronomical Society, 2007)

In this paper, the average brightness temperatures and surface brightnesses at 1420, 820 and 408 MHz of the six main Galactic radio-continuum loops are derived, as are their radio spectral indices. The temperatures and ...

#### New integral representations of the polylogarithm function

(Proceedings of the Royal Society. A: Mathematical, Physical and Engineering Sciences, 2007)

Maximon has recently given an excellent summary of the properties of the Euler dilogarithm function and the frequently used generalizations of the dilogarithm, the most important among them being the polylogarithm function ...

#### Stacking vs. CH-pi interactions between chelate and aryl rings in crystal structures of square-planar transition metal complexes

(CrystEngComm, 2007)

The crystal structures of square-planar transition-metal complexes from the Cambridge Structural Database (CSD) with close contacts between planar chelate rings and aryl rings containing six carbon atoms (C-6- aryl) were ...

#### Second-order theory of helical hexapole lens of infinite length

(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2007)

Expressions which can be used to calculate the focusing coefficients applicable to the interior regions (no fringe fields) of magnetic helical hexapole lenses of infinite length have been derived through second-order. It ...

#### Closed-form evaluation of some families of definite tangent and secant integrals

(Integral Transforms and Special Functions, 2007)

Several families of definite integrals involving the tangent or secant function have been evaluated in closed form by making use of the elementary arguments. Some of them are expressible in terms of a finite combination ...
