Principi i istorija odnosa arhitekture i akustike / Principles and history of the relatedness of architecture and acoustics.
(Univerzitet u Beogradu, Studije pri univerzitetu, 2016)
Istraživanje zvuka u istoriji arhitekture često je nepravedno zanemareno u senci vizuelnih aspekata graditeljstva. Pored toga što ima suštinski značaj za opažanje okruženja i orjentaciju u prostoru, zvuk je kroz istoriju ...
Dejstvo etarskih ulja anisa, morača i mirođije i njihovih dominantnih komponenti na larve gubara (Lymantria dispar L.) / The effect of essential oils of anise, fennel and dill and their dominant components on gypsy moth larvae (Lymantria dispar L.)
(Univerzitet u Beogradu, Poljoprivredni fakultet, 2016)
U radu je ispitivano delovanje alkoholnih rastvora etarskih ulja anisa, mirođije i morača i njihovih dominantnih komponenata trans-anetola i karvona na gusenice gubara (Lymantria dispar L.). Antifidna aktivnost etarskih ...
Morfološka i genetička diferencijacija kečige (Acipenser ruthenus L.) u srednjem i donjem toku Dunava / Morphological and genetic differentiation of sterlet (Acipenser ruthenus L.) from the middle and lower Danube section
(Univerzitet u Beogradu, Biološki fakultet, 2016)
Kečiga (Acipenser ruthenus L., 1758) predstavlja potamodromnu jesetarsku vrstu, koja naseljava reke u slivovima Crnog, Azovskog, Kaspijskog, Baltičkog, Belog, Barencovog i Kara mora. Značajan pad brojnosti usled izlova ...
Spark plasma sintering of hydrothermally synthesized bismuth ferrite
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2016)
Bismuth ferrite, BiFeO3 (BFO), powder was synthesized by hydrothermal method from Bi(NO3)(3)center dot 5H(2)O and Fe(NO3)(3)center dot 9H(2)O as precursors. The synthesized powder was further sintered using spark plasma ...
Antioxidative response in variegated Pelargonium zonale leaves and generation of extracellular H2O2 in (peri)vascular tissue induced by sunlight and paraquat
(Elsevier Gmbh, Munich, 2016)
In this study we exposed variegated leaves of Pelargonium zonale to strong sunlight (>1100 mu mol m(-2) s(-1) of photosynthetically active radiation) with and without paraquat (Pq), with the aim to elucidate the mechanisms ...
Razvoj imobilisanih sistema peroksidaze iz rena (Armoracia rusticana) za polimerizacione reakcije i uklanjanje fenola iz otpadnih voda / Development of immobilized horse radish (Armoracia rusticana) peroxidase for polymerization reactions and removal of phenols from waste waters
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2016)
U prvom delu ove teze je makroporozni kopolimer glicidil metakrilata i etilen glikol dimetakrilata, poly(GMA-co-EGDMA) sa dijametrom čestica od 150 do 500 μm i različitim karakteristikama površine i različitom srednjom ...
Determination of the sources of nitrate and the microbiological sources of pollution in the Sava River Basin
(Elsevier, Amsterdam, 2016)
Coupled measurements of nitrate (NO3-), nitrogen (N), and oxygen (O) isotopic composition (delta N-15(NO3) and delta O-18(NO3)) were used to investigate the sources and processes of N cycling, while the microbial source ...
Structural, ferroelectric and magnetic properties of BiFeO3 synthesized by sonochemically assisted hydrothermal and hydro-evaporation chemical methods
(Elsevier Sci Ltd, Oxford, 2016)
BiFeO3 powders were synthesized by sonochemically assisted hydrothermal and hydro-evaporation methods. The X-ray diffraction confirmed the presence of secondary phases, Bi25FeO39 and Bi2Fe4O9, in as prepared BiFeO3 powders. ...
Comparison of Photoacoustic Signals in Photosynthetic and Nonphotosynthetic Leaf Tissues of Variegated Pelargonium zonale
(Springer/Plenum Publishers, New York, 2016)
Green-white variegated leaves of Pelargonium zonale were studied using the photoacoustic method. Our aim was to characterize photosynthetically active green tissue and nonphotosynthetically active white tissue by the ...
Comparison of macromolecular interactions in the cell walls of hardwood, softwood and maize by fluorescence and FTIR spectroscopy, differential polarization laser scanning microscopy and X-ray diffraction
(Springer, New York, 2016)
Interactions between macromolecules in the cell walls of different plant origin were compared, namely spruce wood (Picea omorika (PaniA double dagger) PurkiAe) as an example of softwood, maple wood (Acer platanoides L.) ...
