Optimization of injected radiotracer volume for flow rate measurement in closed conduits / Optimizacija zapremine radioaktivnog obeleživača pri merenju zapreminskog protoka u zatvorenim cevovodima
(Belgrade : Association of the Chemical Engineers of Serbia, 2020)
In chemical processes it is essential that the flow in the process is accurately defined. Fluid velocity measurements are important for fluid flow quality performance in flow systems. This study focuses on determination ...
Can a benthic diatom community complement chemical analyses and discriminate between disturbed and undisturbed saline wetland habitats?
(Springer, 2021)
Soda pans are protected in the European
Union as Natura 2000 areas in the category of
‘‘Pannonic saline steppes and marshes’’. There are at
least six soda pans of reference status in Serbia and

Pinnularia baetica sp. nov. (Bacillarophyceae): Comparison with other panduriform species in the Mediterranean area
(Magnolia Press, 2020)
A new freshwater diatom species Pinnularia baetica sp. nov. is described from two different ponds from the Mediterranean
area: Andalucia (South of Spain) and Lake Livadičko, Serbia. The species is described by observations ...
Microstructure, roughness, and corrosion resistance of X5CrNi18-10 austenite stainless steel welded joint / X Mikrostruktura , hrapavost i otpornost na koroziju zavarenog spoja austenitnog nerđajućeg čelika X5CrNi18-10
(Belgrade : Serbian Chemical Society, 2021)
The influence of the microstructure of X5CrNi18-10 stainless steel welded joint on its resistance to general, pitting, and intergranular corrosion was analyzed. The structure of weld metal, heat affected zone (HAZ) and ...
Bioremediation of river sediment polluted with polychlorinated biphenyls: A laboratory study / Биодеградација полихлорованих бифенила у речном седименту: лабораторијска студија
(Belgrade : Serbian Chemical Society, 2022)
Persistent organic pollutants (POPs) are lipophilic, constant and bioaccumulative toxic compounds. In general, they are considered resistant to biological, photolytic, and chemical degradation with polychlorinated biphenyls ...
Flavonoids of the Heartwood of Cotinus coggygria Scop. Showing Protective Effect on Human Lymphocyte DNA
(SAGE Publications, 2021)
In continuation of our study on Cotinus coggygria from Serbia, 10 known flavonoids (1-10) were isolated from the methylene chloride/ methanol extract of the heartwood. They were tested for in vitro protective effect against ...
Nonacosan-10-ol and n-Alkanes in Leaves of Pinus pinaster
