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 ...
Closed-form evaluation of some families of cotangent and cosecant integrals
(Integral Transforms and Special Functions, 2008)
Several families of integrals involving the cotangent or cosecant function have been evaluated in closed form by making use of elementary arguments. Some of them are expressible in terms of the values of the (generalized) ...
Kinetics of the alpha-beta Phase Transformation in Seeded Si3N4 Ceramics
(Science of Sintering, 2008)
The alpha-beta phase transformation in Si3N4 was studied for seeded samples using all Y2O3-Al2O3 mixture as a sintering aid. The concentration of beta-seeds varied from 0 to 5 wt.%. The results showed that alpha-beta phase ...
Bifurcations in nonlinear models of fluid-conveying pipes supported at both ends
(Journal of Fluids and Structures, 2006)
Stationary bifurcations in several nonlinear models of fluid conveying pipes fixed at both ends are analyzed with the use of Lyapunov-Schrnidt reduction and singularity theory. Influence of the gravitational force, curvature ...
A Ph-negative chronic myeloid leukemia with a complex BCR/ABL rearrangement and a t(6;9)(p21;q34.1)
(Cancer Genetics and Cytogenetics, 2006)
Chronic myeloid leukemia (CML) is a clonal malignant disorder of a pluripotent hematopoetic stem cell characterized by the presence of the Philadelphia (Ph) chromosome in more than 90% of patients. Cryptic or masked BCR/ABL ...
Nanoengineering of inorganic and hybrid composites
(Materials Science Forum, 2000)
The engineering of materials and devices on the nanometer scale is of considerable current interest in electronics, optics, catalysis, ceramics and magnetic storage. Different methodologies of processing that lead to the ...
Mixed ligand Co(II), Ni(II) and Cu(II) complexes containing terephthalato ligands. Crystal structures of diaqua(2,2 -dipyridylamine)(terephthalato)metal(II) trihydrates (metal = cobalt or nickel)
(Polyhedron, 2000)
A series of nine ternary Co(II), Ni(II) and Cu(II) complexes with some aromatic diamines and dianion of terephthalic acid (tpht) have been synthesized and characterized by elemental analysis, magnetic susceptibility ...
Behavior of long-lived radionuclides in the Danube river ecosystem in Serbia
(Journal of Radioanalytical and Nuclear Chemistry, 2006)
Radioactivity of water and sediments from the Danube river in its course through Serbia during 2001-2003 years has been tested by alpha- and gamma-ray spectrometry. Except for cesium originating from Chernobyl, the ...
Matrix-assisted laser desorption and ionisation time-of-flight mass spectrometry of Pt(II) and Pd(II) complexes
(Polyhedron, 2009)
In this work, we have analysed matrix-assisted laser desorption and ionisation time-of-flight (MALDI-TOF) mass spectra of [PtCl(2)(en)], [PtCl(2)(dach)] and [PdCl(dien)]Cl acquired either with 2,5-dihydroxybenzoic acid ...
Optical properties of Hg1-xMnxTe1-ySey
(Infrared Physics and Technology, 2005)
Far-infrared reflectivity spectra of Hg1-xMnxTe1-ySey (0.01 and LE; x and LE; 0.14, 0.01 and LE; y and LE; 0.1) single crystals were measured in the 80-420cm(-1) range at room temperature. The analysis of the far-infrared ...
