Pyrolysis of pine and beech wood under isothermal conditions: the conventional kinetic approach
(Research on Chemical Intermediates, 2015)
Pyrolysis of pine and beech wood was investigated by isothermal thermogravimetry at five different temperatures (280, 290, 300, 310, and 320 A degrees C) in an atmosphere of flowing nitrogen. It was found that isothermal ...
The effect of gamma irradiation in air and inert atmosphere on structure and properties of unfilled or glass fibre-reinforced polyamide 6
(Springer, 2016)
Crosslinking of polyamide 6 (PA) and filled one with glass fibres (PA/GF) was initiated via macroradical formation by gamma irradiation either in air or in inert argon atmosphere. The crosslinked portion was found to start ...
Composite profile of the Fe K alpha spectral line emitted from a binary system of supermassive black holes
(Advances in Space Research, 2014)
We used a model of a relativistic accretion disk around a supermassive black hole (SMBH), based on ray-tracing method in the Kerr metric, to study the variations of the composite Fe K alpha line emitted from two accretion ...
RR interval-respiratory signal waveform modeling in human slow paced and spontaneous breathing
(Respiratory Physiology and Neurobiology, 2014)
Our aim was to model the dependence of respiratory sinus arrhythmia (RSA) on the respiratory waveform and to elucidate underlying mechanisms of cardiorespiratory coupling. In 30 subjects, RR interval and respiratory signal ...
Assessing the dispersive and electrostatic components of the selenium-aromatic interaction energy by DFT
(Journal of Molecular Modeling, 2017)
Selenium has been increasingly recognized as an important element in biological systems, which participates in numerous biochemical processes in organisms, notably in enzyme reactions. Selenium can substitute sulfur of ...
Annealing-induced structural rearrangement and optical band gap change in Mg-Ni-H thin films
(Materials Research Express, 2017)
It is well known that optical properties of Mg-Ni-H films can be tuned by hydrogen uptake from Mg-Ni-H and upload into Mg-Ni systems. In this work we show that modulation of optical properties of Mg-Ni-H can take place as ...
Experimental Design Optimization of the Determination of Total Halogens in Coal by Combustion-Ion Chromatography
(Analytical Letters, 2015)
Determination of total halogens in coal was investigated with oxygen bomb combustion followed by ion chromatography. Experimental parameters were optimized by fractional factorial design and response surface methodology. ...
Defect induced wave-packet dynamics in linear one-dimensional photonic lattices
(Physica Scripta, 2015)
We study numerically light beam propagation across uniform, linear, one-dimensional photonic lattice possessing one nonlinear defect. Depending on the strength of nonlinear defect, input beam position and phase shift, ...
Weighted Sum of Gray Gases Model Optimization for Numerical Investigations of Processes inside Pulverized Coal-Fired Furnaces
(Journal of Thermal Science, 2017)
The effects of the number of significant figures (NSF) in the interpolation polynomial coefficients (IPCs) of the weighted sum of gray gases model (WSGM) on results of numerical investigations and WSGM optimization were ...
Limit Representations of Riemanns Zeta Function
(American Mathematical Monthly, 2012)
In this article, it is shown that Riemanns zeta function zeta(s) admits two limit representations when R(s) GT 1. Each of these limit representations is deduced by using simple arguments based upon the classical Tannerys ...
