A supplement to the knowledge of the flora of Sirinićka Župa at the bottom of the Šara Mountains
(Department of Biology and Ecology, Faculty of Sciences and Mathematics, University of Niš Biological Society “Dr Sava Petrović” Niš, 2016)
The intensive preliminary floristic studies, carried out between March and
August, 2015, yielded the herbaric material consisting of 261 taxa collected at the
bottom of the northern slopes of the Šara mountain massif, ...
Silene noctiflora, present in the flora of Kosovo and Metohija (Serbia)
(Department of Biology and Ecology, Faculty of Sciences and Mathematics, University of Niš Biological Society “Dr Sava Petrović” Niš, 2016)
Studying the flora of the plain part of Kosovo and Metohija, in the village of
Gračanica, on the eastern rim of the Kosovo basin (approximately 10 km to the south of Priština), near the Gračanka stream, we identified a ...
Autocombustion synthesis and characterization of Ni1-xZnxFe2O4
(COST, Advances in Ferroelectric and Multiferroics. Institut of Physics, Academy of Sciences of the Czech Republic, Češka Republika, 2013, 2013)
Nickel ferrite(NF) and nickel zinc ferrite(NZF) powders were prepared by autocombustion method starting from nickel, zinc and iron nitrates [1]. After the process of self – ignition, fine precursor powder was thermally ...
Pedosequences on spilites
(Srpsko društvo za proučavanje zemljišta, Beograd, 2010)
Na planini Tumba u Južnoj Srbiji izdvojena su zemljišta na spilitiraa, specifičnom supstratu nastalom submarinskim utiskivanjem lave u nekonsolidovane škriljce. Ustanovljena je pedosekvenca koju čine litosol -regosol ...
Creating aperiodic photonic structures by synthesized Mathieu-Gauss beams
(Physical Review A, 2017)
We demonstrate a kind of aperiodic photonic structure realized using the interference of multiple Mathieu-Gauss beams. Depending on the beam configurations, their mutual distances, angles of rotation, or phase relations ...
Elliptical vortex necklaces in Mathieu lattices
(Physical Review A, 2018)
We demonstrate unusual kinds of discrete vortex beams, elliptical necklaces, realized by Mathieu photonic lattices. Varying the order of the Mathieu lattices and their ellipticity, we can control the shape and size of such ...
Cell wall-bound phenols, lignin content and peroxidase activity in Dioscorea balcanica stem
(Hierarchical structure and mechanical characterization of wood, Helsinki, Finland, 2011)
Sprouting duration and Pseudomonas spp. impact on biological viability of potato seed tubers
(Beograd: Udruzenje mikrobioioga Srbije, 2011)
Counterpropagating solitons at boundary of photonic lattices
(Optics Letters, 2010)
We study numerically the interaction of two counterpropagating (CP) optical beams near the boundary of a truncated one-dimensional photonic lattice. We demonstrate that the mutual coupling of beams suppresses the effective ...
