Biotehnološki postupak uklanjanja sintetičkih boja iz otpadnih voda imobilisanom peroksidazom iz rena
(Novi Sad : Prirodno-matematički fakultet, 2021)
Opšte je poznata činjenica da postoji veliki ekološki problem zagađenja životne sredine
otpadnim vodama što zahteva kolektivne napore da bi se sprečila nadolazeća ekološka katastrofa.
U ovom radu je razvijen postupak ...
Microeconomics of the materials and energents consumption in a simulated copper casting process
(Edimet SpA, 2012)
An analytical model for the optimization of the consumption of materials and energents in a typical copper casting process based on a standard simulation procedure is presented. The proposed microeconomic analysis in ...
Structural Design of Safety Steel Device of Railway Vehicles Through Analytical and Experimental Investigations
(Budapest Tech Polytechnical Institution, 2022)
The subject of this paper is the structural design of a safety steel device that is located between the standard wagon buffer and the collision energy absorber. The safety steel device is a sacrifical part able to withstand ...

Sensory properties of new films based on poly(vinyl-alcohol) and pyridone azo dyes
(Niš : RAD Centre, 2023)
Polymeric materials are widely used in the chemical and optical industries, the packaging materials industry, and biomedicine. New technologies and the search for innovative and sustainable solutions have contributed to ...
A kinetic study of electrochemical decolorization of arylazo pyridone dyes
(Belgrade : Serbian Chemical Society, 2013)
Electrocatalytic decolorization of arylazo pyridone dyes (Fig. 1) was investigated in the presence of NaCl using DSA Ti/PtOx electrode in diluted NaOH. Decolorization can be attributed to the indirect oxidation of the ...
Numerical analysis of fracture of non-standard ring specimen for examination of axially flawed cylindrical structures
(14th International Conference on Fracture, ICF 2017, 2017)
Integrity of cylindrical structures, such as pipes and small-scale pressure vessels, is typically assessed by testing fracture mechanics specimens, like compact tensile CT or single-edge notched bending, SENB. However, ...
Ductile crack growth initiation in welded joints - Micromechanical approach
(Welding in the World, 2008)
The integrity of welded structures depends on the load-carrying capacities of their welded joints. Having in mind that welding process produces a large microstructural gradient through the weld, resulting in variation of ...
CHARACTERIZATION OF TEA AQUEOUS EXTRACTS AND THEIR UTILIZATION FOR DYEING AND FUNCTIONALIZING FABRICS OF DIFFERENT CHEMICAL COMPOSITIONS
(Society of Chemists and Technologists of Macedonia, 2023)
Green, black, rooibos, and hibiscus tea (GT, BT, RT, and HT) aqueous extracts were prepared and
characterized in terms of total flavonoids (TFC) and total phenolic (TPC) contents and antioxidant and antimicrobial activities. ...
Comparative Study of the Microstructure and Properties of Cast-Fabricated and 3D-Printed Laser-Sintered Co–Cr Alloys for Removable Partial Denture Frameworks
(MDPI, 2023)
Since additive technologies in dentistry are gradually replacing metal casting technology, it is necessary to evaluate new dental constructions intended for the development of removable partial denture frameworks. The aim ...
