New data on sterlet (acipenser ruthenus l.) Genetic diversity in the middle and lower danube sections, based on mitochondrial dna analyses
(Društvo genetičara Srbije, Beograd, 2015)
Poor regulated fishery, pollution, fragmentation and loss of habitat are most important factors influencing decline of sterlet population worldwide. In Middle and Lower Danube region, this species still have significant ...
Structural and Electronic Properties of Pseudobrookite
(Belgrade : Institute for Multidisciplinary Research, University of Belgrade, 2015)
Starting powders of TiO2 (anatase) and Fe2O3 (hematite) were mixed in the molar ratio 1:1. Pseudobrookite powder was obtained by a combined milling/calcination procedure. Particle size distribution was analyzed on a laser ...
Two step sintering of the ZnTiO3 nanopowder
(Belgrade : Institute for Multidisciplinary Research, University of Belgrade, 2015)
Metastabile nanopowder ZnTiO3 pressed into cylindrical compacts at 200 MPa was submitted to conventional heating with isothermal holding at 931oC for 10 minutes, 25 minutes and 40 minutes. Same compacts were heated with ...
The Effects of Aggressive Environments on the Properties of Fly Ash based Geopolymers
(IOP Publishing Ltd, Bristol, 2015)
This paper analyzes the effects of two different aggressive environments, concentrated ammonium nitrate solution (480 g/dm(3)) and sodium sulphate solution (50 g/dm(3)), on the structure and mechanical strength of fly ash ...
Identification of phenolic compounds in cecidogen and Linaria vulgaris. Changes in phenolic metabolism during gall formation induced by Rhinusa pilosa
(Serbian Plant Physiology SocietyInstitute for Biological Research “Siniša Stanković” – National Institute of Republic of Serbia, University of Belgrade, 2015)
Rhinusa pilosa (Gyllenhaal) (Coleoptera, Curculionidae) induces galls in Linaria vulgaris Mill., Yellow or
common toadflax (Plantaginaceae). Gall is defined as atypical plant growth induced by host-specific organisms,
and ...
Relation between sputtering parameters and optical and electrical properties of Ga doped ITO transparent conductive oxide
(Elsevier Science Bv, Amsterdam, 2015)
A ceramic target with Ga:In:Sn=4:64:32 metal ratio has been sintered and used for RF sputtering process to develop high quality Ga doped ITO (GITO) transparent conductive oxide layers, particularly for photovoltaic ...
Svetlost kao konstituent ikonopisa: hemijski, fizički, fiziološki i teološki aspekti / Light as a constituent of icon painting: chemical, physical, physiological and theological aspects
(Univerzitet u Beogradu, Studije pri univerzitetu, 2015)
U doktorskoj disertaciji razmatran je pojam svetlosti i njene povezanosti sa naukom i umetnošću kroz istoriju civilizacije kao i u savremeno doba. Pristup koji obuhvata različite aspekte istraživanja svetlosti nazvan je ...
Anticancer properties of nanoceria
(International Max Planck Research School for Molecular Biology in Gottingen, 2015)
CeO2 (nanoceria) is the most important rare-earth oxide, which application is rapidly emerging. These nanoparticles are potent free radical scavengers, due to coexistence of Ce3+ and Ce4+ ions and formation of oxygen ...
Impact fragmentation of nanoscale projectiles at ultrahigh striking velocities
(Springer Nature, 2015)
Molecular-dynamics simulations of the
classic Taylor experiment are performed to investigate
some general trends of impact fragmentation at ultrahigh
striking velocities. The striking velocities of flatended,
monocrystalline, ...
Comparison of two alkali-activated systems: mechanically activated fly ash and fly ash-blast furnace slag blends
(Elsevier Science Bv, Amsterdam, 2015)
Poor reactivity of fly ash (FA) in alkali activation process can be improved either by mechanical activation of fly ash or by blending fly ash with more reactive material, such as blast furnace slag (BFS). Both options ...
