Anti-IgG antibodies from sera of healthy individuals neutralize HIV-1 primary isolates
(Current HIV Research, 2007)
Immunoglobulins (Ig) of pooled healthy human sera were purified by affinity chromatography based on their reactivity with human IgG. This Ig fraction represent connected, natural antibodies (NAbs) and here are denoted as ...
Summation of a family of finite secant sums
(Applied Mathematics and Computation, 2007)
We use contour integrals and the Cauchy residue theorem in order to derive several summation formulas, in terms of the higher-order Bernoulli polynomials and the ordinary Bernoulli and Euler polynomials, for a remarkably ...
Analysis of isothermal sintering of zinc-titanate doped with MgO
(Science of Sintering, 2007)
The aim of this work was analysis of isothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, TiO2 and MgO (0, 1.25 and 2.5%) were mechanically activated 15 minutes ...
Hydrothermal treatment of electrochemically synthesised nanocrystalline magnetic iron oxide powder
(Science of Sintering, 2007)
Magnetic iron oxide nano-powders were synthesised electrochemically, using a low-carbon steel electrode immersed in a NaCl aqueous solution, at constant temperature of the electrolyte, pH and current density. In the second ...
Radiation-induced degradation of hydroxyapatite/poly L-lactide composite biomaterial
(Radiation Physics and Chemistry, 2007)
The effects of gamma irradiation on the structure and properties of hydroxyapatite/poly L-lactide (HAp/PLLA) biomaterial have been investigated. Effects of radiation on microstructure, degradation of polymer part and thermal ...
Values of the polygamma functions at rational arguments
(Journal of Physics. A: Mathematical and Theoretical, 2007)
Gauss in 1812, in his celebrated memoir on the hypergeometric series, presented a remarkable formula for the psi (or digamma) function, psi(z), at rational arguments z, which can be expressed in terms of elementary functions. ...
Diffractive open charm production in deep-inelastic scattering and photoproduction at HERA
(European Physical Journal C. Particles and Fields, 2007)
Measurements are presented of diffractive open charm production at HERA. The event topology is given by ep - GT eXY where the system X contains at least one charmed hadron and is well separated by a large rapidity gap from ...
Search for baryonic resonances decaying to Xi pi in deep-inelastic scattering at HERA
(European Physical Journal C. Particles and Fields, 2007)
A search for narrow baryonic resonances decaying into Xi(-)pi(-) or Xi(-)pi(+) and their antiparticles is carried out with the H1 detector using deep inelastic scattering events at HERA in the range of negative photon ...
Carbon monoxide oxidation on Au(111) surface decorated by spontaneously deposited Pt
(Electrochimica Acta, 2007)
Platinum is deposited spontaneously on Au(1 1 1) surface from 1 mM H-2 PtCl6 + 1 M HClO4 solution using multiple deposition procedure. X-ray photoelectron spectroscopy (XPS) analysis has shown that after immersion into the ...
Dilatometric study of Si3N4-LAS system
(Ceramics-silikaty, 2007)
The possibility of using Li-exchanged zeolite (LAS) as additive for densification of Si3N4 ceramic was studied. Dilatometry was used to measure the shrinkage behavior of green bodies prepared from zeolitic precursor and ...
