Who is the better candidate? Macroinvertebrates and diatoms for ecological status assessment of Sava Lake (Serbia)
(Zagreb : Croatian Association of Freshwater Ecologists, 2019)
Sava Lake was created from the right arm of the Sava River, and the inhabitants of Belgrade use the lake intensively for swimming and bathing. We analysed macrozoobenthos and epilithic diatom communities at six sites from ...
Modelling and Multi-Criteria Analysis of Anaerobic Digestion Process to Get Upgraded Methane from Bio-Residues in the City of Reykjavik
(MDPI, 2019)
Anaerobic digestion of urban organic wastes, farming slurries or sewage sludge is a
common practice in waste treatment plants. In the city of Reykjavik, the organic waste fraction
constituted by 60% of biomass and 40% ...
Biodiesel synthesis over green catalyst: The effect of thermal treatment of CaO/Zeolite precursor on catalytic activity
(Belgrade : Serbian Chemical Society, 2019)
The green CaO/Zeolite catalyst for methanolysis of fatty oils was synthesized entirely from the waste materials. CaO derived from chicken eggshell was loaded onto fly ashbased zeolite catalyst carrier by the wet impregnation ...
Intensification of a chemical reactor for methanol synthesis through forced periodic operations- Evaluation based on Nonlinear Frequency Response Analysis
(2nd International Process Intensification Conference, Leuven, Belgium, 2019)
In this work, the NFR method is implemented for evaluation of possible improvement for the reaction of methanol synthesis by hydrogenation of CO and CO2, using a standard Cu/ZnO/Al2O3 catalyst. For start, a forced periodically ...
Nickel doped titanate catalysts for photocatalytic hydrogen generation
(Belgrade : Institute of Technical Sciences of SASA, 2019)
This study will focus on investigation of photocatalytic hydrogen production activity over low cost Ni modified titanates, as alternatives for highly cost and low-abundance noble metal based catalysts. The catalysts with ...
Prečišćavanje otpadnih voda primenom ozonizacije / Purification of waste water using ozonization
(Beograd : Beogradska politehnika, 2019)
Usled razvoja industrije i rastom populacije tokom poslednjih godina javljaju se
problemi u vezi sa otpadnim vodama iz proizvodnje koje je neophodno rešavati na ekološki i
ekonomičan način. Sve otpadne vode iz postrojenja ...
Forced Periodic Operation: Effect of shapes for two simultaneously imposed modulations
(German reaction Engineering Meeting (DECHEMA), Wuerzburg, Germany, 2019)
The classical design of continuous chemical reactors exploits steady-state operation, which is optimized and maintained by appropriate control systems. Nevertheless, it is well-known that the reactor performance can be ...
Alumina production from purified Bayer liquor / Proizvodnja glinice iz pročišćene Bayerove otopine
(Hrvatska: Hrvatsko društvo kemijskih inženjera i tehnologa
(HDKI), 2019)
Removal of some impurities from Bayer liquor, such as zinc compounds, allows obtaining alumina with low content of impurities incorporated in the crystalline structure. Impurities in alumina influence the quality of products ...
Green frogs skin harbours microbiota treasure
(Taylor & Francis, 2019)
Cutaneous microbiota of amphibians is considered
to be an indicator of the health status of examined
individuals, as well as of environmental factors. In
that sense the skin of the captured individuals
belonging to ...
