Predikcija brzine na 3D štampaču primenom veštačkih neuronskih mreža
(Uniiverzitet u Beogradu - Mašinski fakultet, 2020)
U ovom radu, izvršena je analiza i predikcija brzina štampe u eksploatacionim uslovima. Postoje
odstupanja zadane brzine na štampaču od proračunate stvarne vrednosti. S tim u vezi, postoji i razlika u
vremenima izrade. ...
Laser techniques and couplings with other techniques in contemporary problem solving in theory and practice
(Academy of Sciences and Arts of the Republic of Srpska / Академија наука и умјетности Републике Српске, 2020)
Problems of today, pro et contra of new breakthroughs in high frequencies and pandemics, seem to have called for even more complex correlations and couplings of the fields: science, empiria (practice), mass-media in mastering ...
Forced periodic reactor operation: Analysis of process and forcing parameters exploiting the nonlinear frequency response method
(WILEY-VCH, 2020)
Continuous chemical reactors are mostly operated under steady-state conditions. However, theoretical studies reveal that forced periodic operation (FPO) can lead to better performance. To predict and optimize FPO, the ...

Microbial degradation of petroleum hydrocarbons - in vitro study
(Federation of European Microbiological Societies (FEMS), 2020)
Pollution of the environment by petroleum products is a global problem, since its extensive exploitation in broad areas.
Microorganisms can degrade or transform toxic, petroleum derivates into harmless products with high ...
Analysis Of Microbial Community In Microbial Fuel Cell System
(Federation of European Microbiological Societies (FEMS), 2020)
This study was aimed to determine the number of various groups of microorganisms in order to
describe the microbial community present in a sample of the Danube river sediment used in
Microbial Fuel Cells (MFC) processes.
Optimization of biodiesel production from waste cooking oil using waste-based CaO/Zeolite catalyst
(Belgrade : Materials Research Society of SerbiaBelgrade : Institute of Technical Sciences of SASA, 2020)
Lignite coal fly ash collected from Serbian thermal power plants was converted into value-added zeolite-like material using a Teflon-lined hydrothermal reactor in an alkali activation process at 150 ºC for 24 h. The obtained ...
Determination of ionization constants of selected monocarbohydrazone derivatives
(Academy of Sciences and Arts of the Republic of Srpska, 2020)
Carbohydrazone derivatives represent a very significant class of compounds due to their wide biological activity. Ionization states of functional groups present in the molecule are of vital importance for understanding of ...
Chemical composition of Origanum dictamnus and Origanum vulgare ssp. hirtum from Greece
(Faculty of Architecture – University of MontenegroFaculty of Philosophy - University of MontenegroBiotecnical faculty - University of Montenegro, 2020)
Most of the Origanum species are locally distributed within the Mediterranean region
where they grow in the mountainous areas on the islands. Due to this, the rate of endemism is high,
as in case of dittany of Crete (O. ...
