Are Shannon entropy and Residual entropy synonyms?
(MDPI, 2015)
At temperatures close to absolute zero, individual symmetric or asymmetric molecules that comprise a thermodynamic system organize themselves into crystals that we can comprehend as macromolecules. Crystals can be ideal ...
Characterization of the sludge generated during the processing of iron ore in Omarska mine
(University of Belgrade, Faculty of Mining and Geology, Center for Environmental Engineering, 2017)
In present paper there were characterized sludge samples generated as an overflow during the processing of iron ore from Omarska mine (Bosnia and Herzegovina). With the aim to improve the utilization of minerals, we are ...

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 ...
Nondestructive evaluation of degradation level for refractory and polymer composite materials in extreme conditions
(Institute for Multidisciplinary Research, 2013)
Non-destructive evaluation of degradation level in extreme condition caused by: thermal shock and cavitation erosion for refractory concrete (LCC) and durability of sulfur concrete in aggressive environment were goal of ...
Concentration method for the mining wastewater-valorization of the copper
(The Regional Environmental Center for Central and Eastern Europe, 2013)
During the mining process of copper exploitation, a large amount of wastewater is generated. Not only do the copper ions contaminate the water but also represent a great loss for the copper production industry. Negative ...
