Influence of the low frequency 10-1000 Hz magnetic field on Saccharomyces cerevisiae respiration activity / Uticaj niskofrekventnog magnetnog polja (10-1000 Hz) na respiracionu aktivnost ćelija kvasca Saccharomyces cerevisiae
(Belgrade : Serbian Chemical Society, 2018)
The effects of electric, magnetic or electromagnetic fields on different microbes have
become a very popular topic nowadays, mostly because the fields could potentially affect
the survival of the microbial cells as well ...
Dielectric spectroscopy of nanocomposites based on iPP and aPS treated in the water solutions of alkali metal salts
(Wiley, Hoboken, 2018)
In this paper, a new simple and environmentally friendly treatment technique for obtaining polymer nanocomposites with appropriate dielectric properties has been presented. Sheets of isotactic polypropylene and atactic ...
Characterization of nickel thin multilayer films electrodeposited under different agitation conditions
(Belgrade : Military Technical Institute, 2018)
Alternate electrodeposition of ordinary and ultrasonic-assisted Ni layers on polycrystalline copper substrates and single-crystal (100)-oriented silicon wafers was used for the formation of composite systems with nickel ...
Predikcija brzine vetra na teritoriji Libije primenom veštačkih neuronskih mreža
(Univerzitet u Beogradu - Mašinski fakultet, 2018)
Libija je zemlja bogata naftom i prirodnim gasom čije učešće u proizvodnji električne energije je preko 90%.
Međutim, sve više su u upotrebi i obnovljivi izvori energije, kao što je energija vetra. U Libiji postoji ...
CAD/CAM tools in risk analysis during designing process
(University of Belgrade, Faculty of Mechanical Engineering, 2018)
By definition, the risk represents suspense in relation to the desired outcomes. According to that, this project includes the algorithm which with the help of the tool CAD/CAM provides step analysis in the process of ...
CO2 conversion enhancement in a periodically operated Sabatier reactor: Nonlinear frequency response analysis and simulation- based Study
(The 25th International Symposium of Chemical Reaction Engineering (ISCRE 25), Florance, Italy, 2018)
Nonlinear frequency response (NFR) analysis was applied on a Sabatier reactor. A substantial improvement in CO2 conversion was predicted under certain conditions. The NFR analysis prediction was validated using a kinetic ...
Petroleum pollution of alluvial sediments near Sava river, Serbia
(Society of Environmental Toxicology and Chemistry Europe, 2018)
The aim of our research was to determine the presence of petroleum pollutants and their vertical migration in the alluvial area of Sava river.
Forced periodic reactor operation with simultaneous modulation of two inputs: Nonlinear frequency response analysis and experimental demonstration
(American Institute of Chemical Engineers Annual Meeting (AIChE Annual Meeting), Pittsburgh, USA, 2018)
The classical design of continuously operated chemical reactors assumes that they are operated in a steady-state which is usually optimized and maintained by using appropriate control systems. Nevertheless, it has been ...
Determination of inorganic anions in herbal tea infusions using ion chromatography / Određivanje neorganskih jona u rastvoru biljnih čajeva jonskom hromatografijom
(Serbia : Matica srpska, 2018)
The ionic content was examined in nine aqueous tea extracts in which time of boiling, acidification of the medium using lemon juice and way of preparation were observed as factors. Ion chromatography was used for determination ...
Crude extracts of cinnamon and oregano spices as components of pullulan based edible films
(Vinča - Belgrade, Serbia : Vinča Institute of nuclear sciences, 2018)
Pullulan based films were prepared with crude extracts of cinnamon and oregano spices. Obtained films were characterized by FTIR-ATR spectroscopy and their antioxidant and antimicrobial properties were evaluated. These ...
