Content and Nutritional Value of Selected Biogenic Elements in Monofloral Sunflower Bee-Collected Pollen from Serbia
(Springer International Publishing, 2020)
Pollen (floral or bee-collected) can be used as a good source of different nutrients including several important biogenic elements (minerals). The aim of this study was to determine content of selected biogenic elements ...
Fractal Reconstruction of Fiber-reinforced Epoxy Microstructure
(Institute of Electrical and Electronics Engineers Inc., 2021)
In the past century, the use of polymers and composites with a polymer matrix has expanded to such a level that today it is impossible to imagine life without these materials. Epoxy resin and epoxy-based composites are ...
Optimization of methanol synthesis under forced dynamic operation
(4th Indo-German Workshop on Advances in Materials, Reaction& Separation Processes, Berlin, Germany, 2020)
Methanol is an essential primary chemical in the chemical industry. Further, there is a
growing interest in using methanol also for chemical energy storage. Excess electrical
wind or solar energy can be converted to ...
Forced periodic reactor operation
(4th Indo-German Workshop on Advances in Materials, Reaction& Separation Processes, Berlin, Germany, 2020)
We used the nonlinear frequency response (NFR) method in order to identify forced periodic conditions under which the acetic acid anhydride hydrolysis (chosen as a test reaction) can be favorably performed in a CSTR. Based ...
Numerical evaluation of aerodynamic performances of vertical-axis wind turbine rotor with flow concentrator
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, Beograd, 2020)
With wind energy extraction constantly increasing, the interest in small-scale urban wind turbines
is also expanding. Given that these machines often work in adverse operating conditions
(Earth’s boundary layer, vortex ...
Examples of Wide Microwave Bandpass Microstrip Filters on Felt Substrate
(Belgrade : Institute of Electrical and Electronics Engineers Inc., 2021)
Application of one type of wide bandpass filter on felt (textile) substrate is introduced. Copper tape and conductive textile are used for metallization (conductive layer). It is an initial work. The patterns were done in ...
Potencijal poljoprivredne biomase u sistemima proizvodnje biogasa u Republici Srbiji / Potential of agricultural biomass in biogas production systems in the Republic of Serbia
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, Beograd, 2020)
Biomasa predstavlja prema zvaničnim podacima najznačajniji potencijal obnovljivih izvora energije u Republici Srbiji. Ona čini oko 63% od ukupnog potencijala, ali za sada njena iskorišćenost nije na zadovoljavajućem nivou. ...
Wind turbine beyond 20 MW – Technology perspective
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, Beograd, 2020)
The trend of wind turbine development has a special significance in the exploitation of renewable
energy sources. At higher altitudes, we have better wind energy utilization higher speed and
their conversion are achieved ...
Does humification take place during biodegradation of petroleum hydrocarbon?
(Society of Physical Chemists of Serbia, 2021)
The aim of this paper was to study using an active consortium of zymogenic microorganisms for ex
situ biodegradation of a petroleum hydrocarbon, along with simultaneous monitoring of the
humification process.
In this ...
Dynamics of diesel biodegradation by Planomicrobium sp isolated from petroleum contaminated soil
(Society of Physical Chemists of Serbia, 2021)
A direct consequence of the use of fossil fuels is the environmental contamination during production, processing and distribution. Microbial biodegradation is efficient technique for cleaning contaminated areas which follows ...
