Solving some problems in field of heat capacity by using of new correlation
(Banja luka : Akademija nauka i umjetnosti RS, 2013)
In the thermodynamics practice, both for semi – ideal and for real gases, the
dependence of the middle specific heat capacity of temperature, is usually determined by experimentally as linear function, mainly, for the ...
New or rarely recorded diatoms taxa from Serbia (Dojkinačka stream, SE Serbia)
(Niš, Serbia : Department of Biology and Ecology, Faculty of Science and Mathematics, University of Niš, 2013)
Diatoms (Bacillariophyta) inhabiting different types of substrate including stone surfaces, sand, mud, filamentous algae and submerged mosses in the Dojkinačka stream (SE Serbia) were studied by light microscopy. Among ...

Anisotropy of refractory concrete subjected to the thermal shock by using the surface analysis
(Bor : University of Belgrade - Technical Faculty in Bor, 2013)
Monitoring and analysis of the material anisotropy during the thermal shock of the refractory concrete was studied. The material was alumina based low cement castable pre-treated at 1300°C for 3 hours. Water quench test ...
Adsorption properties of TENT fly ash in removal of copper from wastewater
(Bor : University of Belgrade - Technical Faculty in Bor, 2013)
The objective of this study was to monitor the behavior of fly ash originated from the power plant Nikola Tesla as a low cost absorbent for removal of copper ions from synthetic aqueous solutions. Fly ash, a potentional ...
Removal of copper, cadmium, and zinc from the mine wastewater in RTB Bor by low cost adsorbent fly ash
(Bor : University of Belgrade - Technical Faculty in Bor, 2013)
Using fly ash, lignite and mixture of lignite and fly ash for the removal of Cu, Cd and Zn from the acid mine wastewater was studied. The batch and dynamic experiments were conducted. Analysis of mine wastewater proved ...
Kinetics of copper adsorption from wastewater by lignite
(Sofia, Bulgaria : Publishing House “St. Ivan Rilski”, 2013)
Kolubara lignite was used as a natural and low cost adsorption material for removal of copper (Cu2+) from the aqueous solutions. As a method, batch adsorption procedure was applied. Results show that domestic lignite is ...
Adsorption isotherms of removing copper from aqueous solutions by low cost adsorbent-lignite
(Sofia, Bulgaria : Publishing House “St. Ivan Rilski”, 2013)
Serbian lignite from ’’Kolubara’’ deposit was used as a low cost adsorbent for removal of copper ions (Cu2+) from aqueous solutions. Lignite was subjected to the elementary and technical analysis as well as BET and FTIR ...
