Systemic NF-kappaB activation in blood cells of breast cancer patients
(Maney Publishing, 2006)
There is a well-established role for reactive oxygen and nitrogen species, chronic inflammation and immune response in the pathogenesis of breast cancer. Complex interactions between breast cancer cells and surrounding ...
Diagenetic relationships between sulphur species and formation of pyrite in coals and sediments
(Taylor & Francis Inc, Philadelphia, 2007)
Based on the abundant minerals in a Miocene freshwater sequence of mixed sediments (pieces of coal in clays, sand-stones and shales) alternating with coal layers, the following main sedimentation environments were ...
Characterization of platinum deposited on carbon hollow fibers / carbon cryogel composites
(Journal of Optoelectronics and Advanced Materials, 2008)
Platinum supported on high surface area carbon material is one of the most intensively studied catalysts. However, physicochemical characteristics and surface chemistry of carbon influence properties of the support itself ...
Removal of volatile organic compounds from activated carbon by thermal Desorption and catalytic combustion
(Maik Nauka/Interperiodica/Springer, New York, 2007)
The thermal desorption of saturated activated carbon discharged from an industrial adsorber and catalytic oxidation of desorbed products over a Pt/Al2O3 catalyst were investigated. The activated carbon is almost completely ...
Electrical Conductivity of Fullerene Derivatives
(Trans Tech Publications, Switzerland, 2003)
In this paper electrical conductivity of fullerene derivatives was investigated. Compared with pure fullerene (molecule C60), which is an insulator (10-12 Sm-1), the measured C60(OH)24 shows several order of magnitude ...
The contributions of high- and low altitude emission sources to the near ground concentrations of air pollutants
(Elsevier Science Inc, New York, 2008)
The scale of transport through the atmosphere depends on the effective height of an emission source, the meteorological conditions and the physico-chemical characteristics of the pollutants. Atmospheric surface temperature ...
Further degradation product of hyperforin from Hypericum perforatum (St. John's Wort)
(Elsevier, 2003)
Repeated examination of the aerial parts of Hypericum Perfomtum yielded a new degradation product of hyperforin (1) namely deoxyfurohyperforin A (2), together with the previously identified furohyperforin (3), furoadhyperforin ...
Introduction of Pt and Pd Nanoclusters in Zeolite Cavities by Thermal Degradation of Acetylacetonates
(Trans Tech Publications, Switzerland, 2004)
Nanodispersed metallic clusters of platinum and palladium were incorporated into NaX
zeolite cavities by impregnation with acetone solution of corresponding acetylacetonates, solvent
evaporation and acetylacetonate ...
N-type silicon electron mobility and its relationship to the kink effect for nano-scaled SOI NMOS devices
(Materials Science Forum, 2007)
Electron mobility for the silicon-based devices is one of the most important parameters, which determine the behavior of components. Mobility depends on silicon purity, doping level, presence of lattice defects and electric ...
Microstructural properties of PZT thin films deposited on LaNIQ 3-coated substrates
(Materials Science Forum, 2007)
The modified polymeric precursor method (Pechini method) was successfully used for the preparation of epitaxial and polycrystalline ferroelectric Pb(Zr0.52Ti0.48)O3 (PZT) thin films. Films were deposited on LaNiO3 (LNO) - ...
