Importance of Applying Risk Analysis to Pressure Equipment Tested by a Special Program / Važnost primene analize rizika kod opreme pod pritiskom koja se ispituje po posebnom programu
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS/ Union of Mechanical and Electrotechnical Engineers and Technicians of Serbia - SMEITSDruštvo za obnovljive izvore električne energije / Society for Renewable Electrical Power Sources, 2020)
According to PED 2014/68 and the Regulation on technical requirements for design, manufac-
ture and conformity assessment of pressure equipment, pressure equipment is divided into high- and
low-level risk level equipment, ...
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 ...
Fractal reconstruction of fiber-reinforced polymer composites
(Belgrade : Serbian Chemical Society, 2021)
Polymers offer the possibility of different reinforcement incorporation due to a broad range of
chemical structures.Along with this feature, their light weight and processing ease made them
a class of materials that have ...
Plasmonic Crystals with Conical Perforations as Multipurpose Optical Elements
(Belgrade : Institute of Electrical and Electronics Engineers Inc., 2021)
Plasmonic crystals exhibit excellent waveguiding and extreme light localizing properties. However, if additionally perforated, their structure assumes vastly enhanced functionality and becomes the basis for e.g. double ...
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 ...
Reuse of Fe-based amorphous alloys containing CRM: study on their temperature behavior
(Springer Science and Business Media LLC, 2020)
In this paper, the physico chemical properties of Fe–based amorphous alloys containing critical raw materials (CRM) were investigated in order to reuse them for photocatalytic degradation of azo dyes. The iron-based metallic ...

Cilj prikazanog istraživanja je utvrđivanje kvalitativne varijabilnosti i relativne zastupljenosti seskviterpenskih ugljovodonika u uzorcima vrste Teucrium montanum L. prikupljenih sa dva različita tipa podloge. Četiri ...
Influence of regime of electrolysis on morphology and structure of copper dendrites / Uticaj režima elektrolize na morfologiju i strukturu dendrita bakra
(Belgrade : Serbian Society of Corrosion and Materials Protection UISKOZAM, 2021)
Comparative analysis of morphological and structural features of copper dendrites obtained by potentiostatic and galvanostatic regimes of electrolysis was made. The 3D (three dimensional) pine-like dendrites composed from ...
Stability of waste-based zeolite supported CaO catalyst for biodiesel production from waste oily feedstocks
(Fuel Science Center, 2021)
Waste-based zeolite supported CaO catalyst (20CaO/ZMFA) was synthesized by ultrasound-assisted impregnation from alcoholic suspension. Zeolite was previously synthesized from lignite coal fly ash (FA) by alkali activation ...
