Biofilm forming microorganisms on various substrata from greenhouse of Botanical Garden “Jevremovac” / Mikroorganizmi u sastavu biofilma s različitih supstrata staklenika Botaničke bašte “Jevremovac”
(Novi Sad : Matica srpska, 2017)
Diversity of subaerial biofilm forming cyanobacteria, algae and fungi was investigated on 10 different substrata from greenhouse of Botanical Garden “Jevremovac”. Out of 37 documented taxa, 16 cyanobacterial and 10 algal ...
Diatom species composition in the Raška river (Southwestern Serbia) / Sastav silikatnih algi reke Raške ( jugozapadna Srbija )
(Serbia : Matica srpska, 2015)
The paper presents data on the composition of epilithic diatoms in the Raška River. Samples were collected by scraping stone surfaces with a brush from 5 localities along the Raška River in April, June, August and November ...
An example of suppression of spurious stop-bands of EBG band-stop filter
(Udruženje za mikrotalasnu tehniku i tehnologiju i IEEE MTT-S Chapter-a Srbije, Beograd, 2011)
Based on the well known theory of infinite periodic structures, analytical theory of EBG (electromagnetic band gap) cells suppressing 6 higher (spurious) stop-bands is developed. Using such cells in a cascade the ...
On some other preferred method for optimizing the welded joint / O jednoj pogodnoj metodi za optimizaciju zavarenog sklopa
(Savez inženjera i tehničara Srbije, Beograd, 2016)
The paper shows an example of performed optimization of sizes in terms of welding costs in a characteristic loaded welded joint. Hence, in the first stage, the variables and constant parameters are defined, and mathematical ...
