Helicoidal Peyrard-Bishop Model of DNA Dynamics
(Journal of Nonlinear Mathematical Physics, 2011)
A nonlinear model describing DNA dynamics, called helicoidal Peyrard-Bishop model, is described. It is shown that the model can explain a local opening of a DNA helix during transcription. An impact of friction forces is ...
Synthesis of ZrO2 Particles Reinforced ZA25 Alloy Composites by Compocasting Process
(Advanced Composite Materials, 2011)
Microstructures and compressive properties of Zn25Al3Cu/ZrO2 particulate composites were studied. The composites were obtained by compocasting process through infiltration of 1 and 3 wt% ZrO2 particles of different size ...
In vitro evaluation of the genotoxicity of ritodrine and verapamil in human lymphocytes
(Human and Experimental Toxicology, 2011)
The aim of this study was to investigate the genotoxic effects of ritodrine and verapamil on human peripheral lymphocytes in vitro using micronucleus (MN) test. Also, fluorescence in situ hybridization (FISH) with a ...
The role of external and internal mass transfer in the process of Cu2+removal by natural mineral sorbents
(Environmental Technology, 2011)
The kinetics of Cu2+ sorption on to zeolite, clay and diatomite was investigated as a function of initial metal concentrations. For consideration of the mass transfer phenomena, single resistance models based on both film ...
A practical approach to virtualization in HEP
(European Physical Journal Plus, 2011)
In the attempt to solve the problem of processing data coming from LHC experiments at CERN at a rate of 15 PB per year, for almost a decade the High Enery Physics (HEP) community has focused its efforts on the development ...
Mislocalization of CDK11/PITSLRE, a regulator of the G2/M phase of the cell cycle, in Alzheimer disease
(Cellular and Molecular Biology Letters, 2011)
Post-mitotic neurons are typically terminally differentiated and in a quiescent status. However, in Alzheimer disease (AD), many neurons display ectopic re-expression of cell cycle-related proteins. Cyclin-dependent kinase ...
Mechanical Properties of Biomorphic Silicon Carbide Ceramics
(Science of Sintering, 2011)
Bioinorphous beta-SiC ceramics were produced from linden wood by impregnation with tetraethyl orthosilicate (TEOS), followed pyrolysis and high temperature treatment at 1580 degrees C. Six specimen groups included charcoal ...
LaYO3:Sm3+ Nanocrystalline Phosphor: Preparation and Emission Properties
(Acta Physica Polonica A, 2011)
Samarium doped LaYO3 nanocrystalline phosphor powders are obtained by polymer complex solution method. Stoichiometric quantities of La2O3, Y2O3 and for dopant ions Sm2O3 were dissolved in hot nitric acid. Polyethylene ...
Heavy Metal and Bacterial Pollution of the Sava River in Serbia
(Arhiv za higijenu rada i toksikologiju, 2011)
The aim of this study was to establish microbial and heavy metal pollution of the Sava River at three locations close to industry and urban areas (Sabac, Obrenovac, Beograd) in Serbia. Heavy metal analysis included Cu, Zn, ...
Distribution and accumulation of heavy metals in the water and sediments of the River Sava
(Journal of the Serbian Chemical Society, 2011)
The distribution and accumulation of assorted heavy metals and a long-lived radionuclide (Cu, Zn, Pb, Cd, U, Th and Cs-137) in the water and sediment of the River Sava (in Serbia) were investigated at three locations in ...
