Oxidation of chlorpyrifos, azinphos-methyl and phorate by myeloperoxidase
(Pesticide Biochemistry and Physiology, 2011)
The present paper deals with the investigations of optimal conditions for the myeloperoxidase (MPO) mediated oxidation of chlorpyrifos, azinphos-methyl and phorate, organophosphorous pesticides (OPs) containing phosphorothionate ...
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 ...
Numerical prediction of critical heat flux in pool boiling with the two-fluid model
(International Journal of Heat and Mass Transfer, 2011)
Three-dimensional numerical simulations of the atmospheric saturated pool boiling are performed with the aim of predicting the critical heat flux. The two-phase mixture in pool boiling is described with the transient ...
Preparation of ZrO2 and ZrO2/SiC powders by carbothermal reduction of ZrSiO4
(Journal of Alloys and Compounds, 2011)
This paper is dealing with the synthesis of zirconia/silicon carbide (ZrO2/SiC) and ZrO2 powders obtained by carbothermal reduction of natural mineral zircon (ZrSiO4). For the first time, the influence of carbon to ZrSiO4 ...
Structural investigation of mechanically activated nanocrystalline BaTiO3 powders
(Elsevier, 2011)
In this article, in order to obtain tetragonal nanocrystalline BaTiO3, structural investigations of mechanically activated BaTiO3 powder have been performed. A mercury porosimetry analysis and scanning electron microscopy ...
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 ...
Effect of dispersed phase viscosity on maximum droplet generation frequency in microchannel emulsification using asymmetric straight-through channels
(Microfluidics and Nanofluidics, 2011)
Uniformly sized droplets of soybean oil, MCT (medium-chain fatty acid triglyceride) oil and n-tetradecane with a Sauter mean diameter of d (3,2) = 26-35 mu m and a distribution span of 0.21-0.25 have been produced at high ...
Influence of Black Hole Spin on the Shape of the Fe K Alpha Spectral Line: the Case of 3c 405
(Baltic Astronomy, 2011)
Here we analyze how the angular momenta (spins) of black holes in the centers of Active Galactic Nuclei (AGN) affect the shape of the Fe K alpha line emitted from their accretion disks. For that purpose, we compared the ...
Pressureless sintering of internally synthesized SiC-TiB2 composites with improved fracture strength
(Journal of Alloys and Compounds, 2011)
SiC-TiB2 particulate composites were fabricated by converting TiO2 to TiB2 through the reaction between TiO2, B4C and C. The presence of initially very fine, in-situ created, TiB2 particles increased driving force for ...
Study of jet shapes in inclusive jet production in pp collisions at root s=7 TeV using the ATLAS detector
(Physical Review D, 2011)
Jet shapes have been measured in inclusive jet production in proton-proton collisions at root s = 7 TeV using 3 pb(-1) of data recorded by the ATLAS experiment at the LHC. Jets are reconstructed using the anti-k(t) algorithm ...
