Oxidized humic acids from the soil of heat power plant / Oksidovane huminske kiseline iz toplane
(Serbia : Serbian Chemical Society, 2020)
Humic acids isolated from the soil of a heat power plant (HA-E) contaminated with oil were analyzed by Fourier transform infrared spectroscopy (FTIR). In comparison with a humic acids standard (HA-S), a lack of an intense ...
Modeling the biodiesel production using the wheat straw ash as a catalyst / Pepeo pšenične slame kao katalizator u proizvodnji biodizela
(Belgrade : Association of the Chemical Engineers of Serbia, 2021)
Wheat straw ash (WSA) was investigated as a new catalyst in biodiesel production from sunflower oil. The catalyst was characterized by temperature-programmed decomposition, X-ray powder diffraction, Hg porosimetry, N2 ...
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 ...
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 ...
The effects of biocides on the growth of aerophytic green algae (Chlorella sp.) isolated from a cave environment
(Beograd : Institut za bioloska istrazivanja, 2021)
Lampenflora communities of bacteria, cyanobacteria, algae, mosses and lichens colonize illuminated show-caves as a consequence of disturbances to the caves’ ecological equilibrium. These communities have unesthetic impacts ...
DNA protective activity of triterpenoids isolated from medicinal mushroom Fomitopsis betulina / DNK protektivna aktivnost triterpena izolovanih iz medicinske gljive Fomitopsis betulina
(Belgrade : Serbian Chemical Society, 2021)
Eleven 31-methylenlanostane triterpenoids, i.e., seven 21- and four 26-oic acids, as well as a lupane triterpenoid betulin, isolated from the fruiting bodies of the mushroom Fomitopsis betulina, were tested for in vitro ...
Early-Middle Miocene paleoenvironmental and paleoclimate changes in the Toplica Basin (Serbia) inferred from plant biomarkers, biochemical and elemental geochemical proxies
(Central Library of the Slovak Academy of Sciences, 2021)
The study investigates the influence of alluvial-lacustrine processes and paleoclimate variations on the distribution of terpenoids and unsubstituted Polycyclic Aromatic Hydrocarbons (PAHs). The XRF, ICP-MS, Rock-Eval, and ...
The influence of grape pomace substrate on quality characterization of Pleurotus ostreatus —Total quality index approach
(Wiley, 2020)
Total quality index approach was used to reflect the quality of Pleurotus ostreatus mushroom, cultivated on grape pomace (P) as food waste substrate and wheat straw (S), in four different combined ratios: 100P; 80P20S; ...
Neural networks and microelectronics parameters distribution measurements depending on sintering temperature and applied voltage
(World Scientific, 2020)
This research is based on the idea to design the interface structure around the grains and thin layers between two grains, as a possible solution for deep microelectronic parameters integrations. The experiments have been ...
Ceramics, materials, microelectronics and graph theory new frontiers
(World Scientific, 2020)
This research is focused on further developing of application and use of graph theory in order to describe relations between grains and to establish control over layers. We used functionalized BaTiO3 nanoparticles coated ...
