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 ...
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 ...
One possibility for graphical representation of real gas energy values for characteristic change of the state / Jedna mogućnost grafičkog predstavljanja energetskih veličina realnog gasa za karakterističnu promenu stanja
(Institut za nuklearne nauke “Vinča” - Društvo termičara Srbije, 2013)
In this paper, for the case of isothermal quasi static characteristic change of the state of real gas is given graphical representation respectively determination of the most important energy values in h-s and T-s diagrams. ...

Cavitation resistance of refractory concrete: Influence of sintering temperature
(Elsevier, 2013)
The purpose of this study was to investigate possible application of refractory concrete in conditions of cavitation effect where the metal materials are usually applied. Also, influence of different sintering temperatures ...
Quantitative evaluation of sulfur-polymer matrix composite quality
(Elsevier, 2013)
In order to predict service life of the sulfur–polymer composite, the samples were subjected to the induced destruction using 10% hydrochloric acid solution. Control specimens were prepared using Portland cement binder. ...
Removal of heavy metals from aqueous solutions using natural and Fe(III) oxyhydroxide clinoptilolite
(Springer, 2013)
The increasing levels of industrial wastewater released to the environment present a serious
threat to human health, living resources, and ecological systems. Fe-modified zeolites were developed and tested for removal of ...
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 ...
