Characterization of clay from Kolubara mining basin, Serbia
(Serbian Ceramic Society, 2019)
During coal exploitation in the Kolubara mining basin, Serbia, clay is deposited as accompanying mineral. The aim of the present study is to analyze the activity concentrations of terrestrial (226Ra, 232Th and 40K) and ...
AN OUTBREAK OF THE SOFT ROT ON CABBAGE
(Plant Protection Society of Serbia, 2019)
Soft rot disease is present on a wide range of plant species worldwide. The symptoms are similar
in most hosts and can be easily recognized by soft, wet, cream colored flesh often surrounded by a
dark margin. The disease ...
DETERMINATION OF ALLELIC PROFILE OF Xanthomonas campestris pv. campestris ISOLATES ORIGINATED FROM CABBAGE
(Plant Protection Society of Serbia, 2019)
Cabbage (Brassica oleracea var. capitata L.) is one of the most important vegetable crop in Ser bia, mainly significant for its richness in beneficial nutrients, both minerals and vitamins. Its yield can
nowadays be ...
Технолошки поступак синтезе термостабилног геополимера на бази електрофилтерског пепела из термоелектране Морава - Свилајнац применом комбинација раствора натријум-силиката и калијум-хидроксида као алкалног активатора
(2016, 2016)
Овим техничким решењем дефинисан је поступак синтезе термостабилног геополимера на бази ЕФП Свијалнац применом комбинација раствора натријум-силиката и калијум-хидроксида као алкалног активатора. Синтетисани геополимери ...
Interaction of UV Irradiation with Thin Films of Organic Molecules
(Atlantis Press, Paris, 2017)
There is an ongoing interest in organic materials due to their application in various organic electronic devices. However stability of organic materials limits their potential use. They are prone to degradation both during ...
Laboratorijski prototip za ispitivanje električnih karakteristika materijala u različitim uslovima atmosfere i temperaturnog režima
(Univerzitet u Beogradu, Institut za multidisciplinarna istraživanja, 2014)
Имајући у виду чињеницу да се електрична својства материјала испитују у различитим условима температуре и атмосфера, постоји потреба да се конструише таква апаратура која ће испуњавати критеријуме за прецизно и безбедно ...
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 ...
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 ...
Control of Airy-beam self-acceleration by photonic lattices
(Physical Review A, 2014)
We demonstrate control over the acceleration of two-dimensional Airy beams propagating in optically induced photonic lattices. Depending on the lattice strength, we observe a slowing-down and suppression of the self-acceleration ...
