The impact of trout farm effluent on diatoms richness in the Rasina river (Serbia)
(Macedonian Ecological Society, 2016)
The Rasina River is right tributary of the Zapadna Morava River, situated in central Serbia. The samples were collected in spring (April), summer (July) and autumn 2011, from 6 localities along the river at an altitudes ...
Diatoms on the green frogs skin (Pelophylax esculentus and P. ridibundus)
(Prague : Charles University in Prague, 2017)
It is known that diatoms may be present on the skin of various animals (whales, dolphins, manatees, turtles…) (Frankovich et al. 2015, Wetzel et al. 2012). In our study diatoms were collected from the skin of two green ...
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 ...
How do newly-described diatom species affect biomonitoring? – An example of Gomphonema paratergestinum vs. G. tergestinum
(Berlin : Botanic Garden and Botanical Museum, Berlin Freie Universität Berlin, 2018)
Over the past decade a great number of new diatom taxa was described, as well as re-definitions and delimitations of taxa from different species complexes have been performed. The reasons for the constant increase in the ...
Optimizacija karakteristične temperature kod kondenzatora s obzirom na tehnoekonomske aspekat / Optimization of characteristic temperature of the condenser considering techno-economic aspect
(VII Međunarodni naučni skup „Savremeni materijali“, Banja Luka, 2014)
U radu je za kondenzatore kao karakteristične grupe rekuperatora toplote, polazeći od funkcije ukupnih troškova kao funkcije cilja, određena optimalna vrednost izlazne temperature rashladnog fluida. Pri ovome izvršena je ...

Novi model za određivanje promene entropije poluidealnog gasa primenom razlomljene temperaturne funkcije / New model for determining of change entropy of semi-ideal gas by using fractional temperature function
(Academy of Sciences and Arts of the Republic of Srpska, 2014)
Kod poluidealnog gasa, promena entropije ne može se odrediti preko srednjeg specifičnog toplotnog kapaciteta na način kao što se određuje promena unutrašnje energije i entalpije, odnosno razmenjena količina toplote. Uzimajući ...
