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 ...
Physicochemical investigation of some archaeometallurgical findings from locality Kmpije (Bor, Serbia)
(Journal of Thermal Analysis and Calorimetry, 2014)
Preliminary results of physicochemical investigation of some archaeometallurgical findings from Kmpije locality in vicinity of Bor (Serbia) are presented in this paper. Ancient samples of prehistoric origin were investigated ...
Elongated titania nanostructures as efficient photocatalysts for degradation of selected herbicides
(Applied Catalysis. B: Environmental, 2014)
Titanium dioxide nanotubes (TNT) were synthesized via hydrothermal method and calcined at various temperatures. The obtained calcined TiO2 nanomaterials with specific elongation orientation were characterized by transmission ...
Synthesis of ultra-thin oxide layer in laser-treated 3x (Al/Fe)/Si multilayer structure
(Journal of Materials Science, 2014)
The conditions of ultra-thin oxide films synthesized as the Al/Fe multilayer structures after the surface treatment with femtosecond laser radiation were studied. Thin films composed of three (Al/Fe) bilayers were deposited ...
Chemical speciation of metals in unpolluted soils of different types: Correlation with soil characteristics and an ANN modelling approach
(Elsevier, 2016)
The distribution of elements in soil fractions affects their mobility and availability and thus their potential beneficial or harmful impact on ecosystems, biota and humans. Different mineralogical and chemical characteristics ...
A novel reduction-oxidation synthetic route for hafnia
(Elsevier, 2016)
Amorphous hafnia (HfO2) powders were synthesized through a novel reduction oxidation route, in which, metal hafnium was reduced from hafnium tetrachloride (HfCl4) by sodium borohydride (NaBH4), and then oxidized in ambient ...
Structural and electrical properties of BaCe(0.9)Ee(0.1)O(2.95) electrolyte for IT-SOFCs
(Electrochimica Acta, 2015)
BaCe(0.9)Ee(0.1)O(2.95) (BCE) nanopowder was synthesized by citric-nitric autocombustion method. Rietveld refinement analysis showed that unit cell volume was slightly larger compared with the most known BaCe0.9Y0.1O2.95, ...
Synthesis and characterization of new Ti-Bi2O3 anode and its use for reactive dye degradation
(Materials Chemistry and Physics, 2015)
This paper reports the synthesis, characterization and application of a Ti-Bi2O3 anode for the electrochemical decolorization of the textile dye Reactive Red 2. The anode was synthesized by electrodeposition on a Ti substrate ...
Study of electron transmission through a platinum tube
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2015)
We have measured 200 eV electron transmission through a single platinum tube of a diameter of 3.3 mm. We find that the transmission of electrons can be detected even at large tilt angles, where the tube is not transparent ...
Web Implementation of Quality Assurance (QA) for X-ray Units in Balkanic Medical Institutions
(Health Physics, 2015)
Diagnostic radiology is the major contributor to the total dose of the population from all artificial sources. In order to reduce radiation exposure and optimize diagnostic x-ray image quality, it is necessary to increase ...
