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 ...
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 ...
UV-irradiation provokes generation of superoxide on cell wall polygalacturonic acid
(Wiley, Hoboken, 2013)
We examined the redox effects of UV irradiation on cell wall isolates from Pisum sativum leaves, and polygalacturonic and galacturonic acid, in the presence of hydrogen peroxide. For this purpose, electron paramagnetic ...
Sadržaj mikroelemenata i teških metala u zemljištima opštine Krupanj
(Srpsko društvo za proučavanje zemljišta, Beograd, 2010)
U radu su prikazani podaci o osnovnim parametrima plodnosti zemljišta i sadržaju nekih mikroelemenata i teških metala (Zn, Mn, Fe, Cd, Ni, Cr, Pb) u zemljištima opštine Krupanj (sa ukupno 281 lokacije). Različiti prirodni ...
Karakterizacija feritnih EMI potiskivača i transformatora korišćenjem vektorskog analizatora mreža / CHARACTERIZATION OF THE FERRITE EMI SUPPRESSORS AND TRANSFORMERS
(Savez službenika privredno upravnih ustanova Jugoslavije, 2010)
U ovom radu su prikazane metode za karakterizaciju feritnih EMI potiskivača i transformatora bazirane na merenju S-parametara, korišćenjem vektorskog analizatora mreža i specijalno razvijenih PCB prilagodnih stepena. Feritni ...
