(Универзитет у Београду, Биолошки факултет, 2013)
kormorana i naseljava sve kontinente izuzev Južne Amerike i Antarktika. Politipska je vrsta u okviru koje se razlikuje pet podvrsta, a Evropu naseljavaju dve: P. carbo carbo – naseljava obalu severnog Atlantika, i P. carbo ...
Ispitivanje orijentacije strukturnih polimera ćelijskog zida kod tvrdog drveta (Acer platanoides L.), mekog drveta (Picea omorika (Pančić) Purkyně) i povijuše (Dioscorea balcanica Košanin)
(Универзитет у Београду, Факултет за физичку хемију, 2018)
Ćelijski zid vlakana drveta može se smatrati kao nano-kompozit, u kojem su celuloza, lignin i hemiceluloze kompleksno povezani. Organizacija i svojstva polimera drveta u velikoj meri određuju svojstva vlakana i drveta, pa ...
Solubilization of inorganic phosphate by endophytic Pseudomonas sp. from French bean nodules
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2014)
Phosphorus (P) is one of the major essential macronutrients for plant growth. Phosphate
solubilizing bacteria (PCB) is a group of heterotrophic bacteria capable of solubilizing organic and
inorganic phosphorus from ...
Biometry and diet of Perccottus glenii Dybowski, 1877 found in stagnant water nearby Veliko Gradište (northeastern Serbia)
(Institute of Marine Biology, University of Montenegro, 2019)
The aim of this study was to describe biometric and feeding characteristics of highly in-vasive species Perccottus glenii in the investigated locality. A total of 85 fish were elec-trofished in the drainage channel located ...
STRUCTURAL CHARACTERISATION AND ORIENTATION OF CELL WALL POLYMERS IN MAIZE LEAVES
(University of Belgrade, Technical Faculty in Bor, 2019)
Cell wall can be considered as a nano-composite in which cellulose, lignin and hemicelluloses are
interconnected in a specific manner. Mechanical and physical propreties of plant fibres are dependent
on the orientation ...
Assesment of genotoxic pollution of the Danube River with comet assay in different tissues of common bream (Abramis brama L. 1758)
(Serbian Genetic Society, Belgrade, Serbia, 2014)
The aim of this study was to assess the genotoxic potential of Danube River at the site Višnjica (downstream Belgrade) on monthly basis over year 2014 in tissues of common bream (A. brama). The level of DNA damage in the ...
Structural, optical and photocatalytic properties of BiFeO3 nanoparticles
(Institute for Multidisciplinary Research, University of Belgrade Kneza Višeslava 1, 11000 Belgrade, Serbia, 2019)
BiFeO3 (BFO) precursor powder was synthesized by ultrasound asissted sol–gel route at relatively low temperature, starting from Bi-nitrate, Fe-nitrate, and ethylene glycol. Structural, optical, and photocatalytic properties ...
Density of the ZnTiO3 nanopowder as a loose powder and as a compact obtained by different methods
(Belgrade : Serbian Ceramic Society, 2013)
Nanopowder density, as well as compact density, is due to powder particle size, different in their values, compared to micron powders. Also, the technique used for density determination induces large mutual value discrepancies. ...
