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 ...
The Effect of Bowl-In-Piston Geometry Layout on Fluid Flow Pattern
(Thermal Science, 2011)
In this paper some results concerning the evolution of 3-D fluid flow pattern through all four strokes in combustion chambers with entirely different bowl-in-piston geometry layouts ranging from omega to simple cylinder ...
Some Subtleties Concerning Fluid Flow and Turbulence Modeling in 4-Valve Engines
(Thermal Science, 2011)
In this paper some results concerning the structure and evolution of fluid flow pattern during induction and compression in 4- valve engines with tilted valves were presented. Results were obtained by dint of multidimensional ...
Diamond deposition on thin cylindrical substrates
(Journal of the Serbian Chemical Society, 2011)
Diamond coatings were deposited onto different cylindrical substrates (Cu, SiC, W and Mo) by the hot filament chemical vapor deposition (CVD) method. Continuous, adhered and well-faceted crystalline coatings of diamond ...
Curing and Mechanical Properties of Chlorosulphonated Polyethylene Rubber Blends
(Chemical Industry and Chemical Engineering Quarterly / CICEQ, 2011)
In this paper, the curing and mechanical properties of two series of prepared blends, i.e., chlorosulphonated polyethylene (CSM)/isobutylene-co-isoprene (IIR) rubber blends and chlorosulphonated polyethylene (CSM)/chlorinated ...
Modified divergence theorem for analysis and optimization of wall reflecting cylindrical UV reactor
(Hemijska industrija, 2011)
In this paper, the modified divergence theorem (MDT), known in earlier literature as the Gauss-Ostrogradsky theorem, was formulated and proposed as a general approach to electromagnetic (EM) radiation, especially ultraviolet ...
Determining the Composition of High Temperature Combustion Products of Fossil Fuel Based on Variational Principles and Geometric Programming
(Thermal Science, 2011)
This paper presents the algorithm and results of a computer program for calculation of complex equilibrium composition for the high temperature fossil fuel combustion products. The method of determining the composition of ...
Influence of chemical agents on the surface area and porosity of active carbon hollow fibers
(Journal of the Serbian Chemical Society, 2011)
Active carbon hollow fibers were prepared from regenerated polysulfone hollow fibers by chemical activation using: disodium hydrogen phosphate 2-hydrate, disodium tetraborate 10-hydrate, hydrogen peroxide, and diammonium ...
Effect of Insulin on Adiponectin and Adiponectin Receptor-1 Expression in Rats with Streptozotocin-induced Type 2 Diabetes
(Journal of Health Science, 2011)
The present study was designed to investigate the effect of insulin on insulin resistance (IR), plasma adiponectin level and expression of adiponectin receptors 1 (AdipoR1) in obese and streptozotocin-induced type 2 diabetic ...
A novel platinum-based nanocatalyst at a niobia-doped titania support for the hydrogen oxidation reaction
(Journal of the Serbian Chemical Society, 2011)
The kinetics of the hydrogen oxidation reaction (HOR) was studied at Pt nanoparticles supported on niobia-doped titania (Pt/N-T). The catalyst support, with the composition of 0.05NbO(2.5-delta)-0.995TiO(2) (0 LT delta LT ...
