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 ...
Influence of cold-rolling deformation and annealing temperature on the grain growth of al-4%mg-mn alloy
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2020)
The propensity of an alloy toward an abnormal grain growth (AGG) severely limits the annealing temperature range, capability for hot forming, and deteriorates mechanical properties. In this work, the results of a study of ...
The role of science in modern society
(Savez hemijskih inženjera, Beograd, 2020)
Optimization and kinetic study of anthraquinone dye removal from colored wastewater using soybean seed as a source of peroxidase
(Macedonian Journal of Chemistry and Chemical Engineering, 2020)
As water contamination emerges as a serious threat to the environment, ventures for cleaner and sustainable solutions are continuously being developed. The present study investigates the ability of crude peroxidase extract ...
Immobilization of Lactobacillus rhamnosus in polyvinyl alcohol/calcium alginate matrix for production of lactic acid
(Springer, New York, 2020)
Immobilization of Lactobacillus rhamnosus ATCC7469 in poly(vinyl alcohol)/calcium alginate (PVA/Ca-alginate) matrix using "freezing-thawing" technique for application in lactic acid (LA) fermentation was studied in this ...
Removal of Fe2+, Zn2+ and Mn2+ from the mining wastewater by lemon peel waste
(Srpsko hemijsko društvo, Beograd, 2020)
This study is aimed to evaluate the possibility of lemon peel, as an agro-industrial waste, to remove Fe2+, Zn2+ and Mn2+ from single aqueous solutions and mining wastewater. For this purpose, the influence of various ...
Multi-criteria ranking of organizational factors affecting the learning quality outcomes in elementary education in Serbia
(Vilnius Gedinimas Technical University, 2020)
The research within this paper is motivated by the opinion that different organizational factors in primary education can have a stronger or weaker impact on the quality of the learning outcome. Organizational factors, ...
Use of carbon paste electrode and modified by gold nanoparticles for selected macrolide antibiotics determination as standard and in pharmaceutical preparations
(Elsevier B.V., 2020)
In this work, carbon paste electrode (CPE) and carbon paste electrode modified with gold nanoparticics (AuNPs/CPE) were employed with rapid direct anodic square wave voltammetry (SWV) for macrolide antibiotics erythromycin ...
