Anisotropy Analysis of Low Cement Concrete by Ultrasonic Measurements and Image Analysis
(International Institute for the Science of Sintering, Beograd, 2016)
The analized material was high alumina low cement castable sintered at three different temperatures. Influence of initial material anisotropy on the thermal shock resistance as well as changes of anisotropy level during ...
Pollution by Urticaceae pollen-influence of selected air pollutants and meteorological parameters
(Springer Heidelberg, Heidelberg, 2016)
The goal of this study was to analyze the influence of pollutants (concentrations of NO2, SO2, and soot in the air) and meteorological parameters (air temperature, humidity, wind speed, air pressure, cloud index) on ...
Nephrococcus serbicus, a new coccoid cyanobacterial species from Bozana Cave, Serbia
(Magnolia Press, Auckland, 2016)
During the investigation of cyanobacterial diversity in Bozana Cave, which is situated in a limestone region in western Serbia, a new species of cyanobacterium belonging to the genus Nephrococcus was found. So far, there ...
Kinetic Analysis of Nonisothermal Reduction of Silica-Supported Nickel Catalyst Precursors in a Hydrogen Atmosphere
(Philadelphia : Taylor & Francis Inc, 2016)
A series of silica-supported nickel catalyst precursors was synthesized with different SiO2/Ni molar ratios. Reduction of Ni catalyst precursors with different SiO2/Ni molar ratios under a hydrogen atmosphere was investigated ...
Mass distributions and morphological and chemical characterization of urban aerosols in the continental Balkan area (Belgrade)
(Springer Heidelberg, Heidelberg, 2016)
This work presents characteristics of atmospheric aerosols of urban central Balkans area, using a size-segregated aerosol sampling method, calculation of mass distributions, SEM/EDX characterization, and ICP/MS analysis. ...
Decarbonylative Dibromination of 5-Phenylthiophene-2-carbaldehyde with Bromine
(Georg Thieme Verlag Kg, Stuttgart, 2016)
The decarbonylative dibromination of 2-thiophenecarboxaldehyde derivatives with bromine under mild conditions is developed. The mechanism for the decarbonylation is investigated by experimental and instrumental techniques ...
Cell cycle, apoptosis, cellular uptake and whole-transcriptome microarray gene expression analysis of HeLa cells treated with a ruthenium(II)-arene complex with an isoquinoline-3-carboxylic acid ligand
(Elsevier Science Inc, New York, 2016)
Ruthenium(II)-arene complexes are promising drug candidates for the therapy of solid tumors. In previous work, seven new compounds of the general formula [Ru(eta(6)-p-cymene)(L1-7)Cl] were synthesized and characterized, ...
Thermodynamic assessment and experimental study of the Al-Ag-Ga phase diagram
(Elsevier, 2016)
Ternary Al-Ag-Ga system was assessed both theoretically using thermodynamic calculations of phase equilibria based on CALPHAD method and experimentally using differential thermal analysis (DTA), scanning electron microscopy ...
Comparison of single extraction procedures and the application of an index for the assessment of heavy metal bioavailability in river sediments
(Springer Heidelberg, Heidelberg, 2016)
Metals in sediments are present in different chemical forms which affect their ability to transfer. The objective of this body of work was to compare different extraction methods for the bioavailability evaluation of some ...
Modelling cholesterol effects on the dynamics of the hypothalamic-pituitary-adrenal (HPA) axis
(Oxford Univ Press, Oxford, 2016)
A mathematical model of the hypothalamic-pituitary-adrenal (HPA) axis with cholesterol as a dynamical variable was derived to investigate the effects of cholesterol, the primary precursor of all steroid hormones, on the ...
