Diversity and ecology of diatoms from peat bog at Pester plateau (Serbia)
(Alfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung (AWI), 2015)
The subjects of the study were various types of diatom communities including epiphytes, benthos and plankton of the peat bog at Pešter plateau. A specific diatom flora inhabits all types of communities, comprising in total ...
Energy Efficient Poly(Lactide) Obtaining by Microwave Synthesis
(University of Maribor Press, 2017)
The world is faced with the consequences of drastic reduction in fossil fuel reserves, because of their widespread use, not only as an energy source, but also as a feedstock for monomers obtaining. In order to solve this ...
Methods for Removal of Phenol from Wastewater / Metode uklanjanja fenola iz otpadne vode
(University of Kragujevac, Faculty of Agronomy, Čačak, 2017)
Phenol is a major pollutant in the wastewater because of its presence in the effluent of major processing and refining plants. It has severe effect on human being, both short term and long term. Various methods are used ...
Fermentation of lignocellulosic renewable resources and hydrogen production
(The Academy of Sciences and Arts of the Republic of Srpska, 2016)
Using cheap renewable raw materials such as lignocellulosic feedstock for hydrogen production by fermentation has great significance and potential to give a major contribution to future clean energy. Using hydrogen as a ...
Proposal for determining the minimum volume of the reservoir for characteristic compressed gases based on the concept of maximum work / Predlog za određivanje minimalne zapremine rezervoara za karakteristične komprimovane gasove na bazi koncepta maksimalnog rada
(Proceedings of 49th International HVAC&R Congress and Exhibition, 2018)
Starting from the main relation for closed thermodynamic systems for maximum work of reverse processes, a general model for determining the minimum volume of the tank containing compressed ideal gases, nitrogen and oxygen, ...

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 ...
Analytical error during selection of reference state in thermodynamic of ideal gas / Analitička greška kod izbora referentnog stanja u termodinamici idealnog gasa
(Banja Luka, Republic of Srpska, Bosnia and Herzegovina : Tehnološki fakultet Univerziteta u Banjoj Luci, 2016)
The paper is based on the fact that the internal energy, enthalpy and enthropy as most important thermodynamic state functions, can not be determined in absolut terms without reference state slections. It is demonstrated ...
