Primena homogenih i heterogenih unapređenih oksidacionih procesa za degradaciju tekstilne antrahinonske boje / The use of homogeneous and heterogeneous advanced oxidation processes for degradation of textile anthraquinone dye
(Универзитет у Нишу, Природно-математички факултет, 07-07-2015)
The subject of this dissertation will be to compare the
degradation efficiency of anthraquinone dye Reactive Blue 19
(RB 19) by homogeneous (H2O2/UV, Fe2+/ H2O2 and
Fe2+/H2O2/UV) and heterogeneous (TiO2/UV, TiO2/UV/H2O2
and ...

(Универзитет у Нишу, Природно-математички факултет, 05-06-2015)
The dissertation is a contribution in defining and studying
different types of partial orders on rings, particularly on
von Neumann regular and Rickart rings, as well as on the
algebras of bounded operators on Banach and ...
Treniranje strukturnih klasifikatora za različite funkcije gubitaka sa primenom na probleme klasifikovanja sekvenci / Training Structured Classifiers for Different Loss Functions with the Application to Sequence Labeling Problems
(Универзитет у Нишу, Природно-математички факултет, 06-07-2015)
This thesis presents algorithms for training structured classifiers over different loss functions. It introduces a new primal subgradient method for the optimization of average sum loss, several extensions of max-margin ...

(Универзитет у Нишу, Природно-математички факултет, 20-02-2015)
In this dissertation, the Drazin inverse of a square complex
matrix is studied. Additive properties of the Drazin inverse are
investigated and some original results are presented. Also,
representations of the Drazin inverse ...
Bioakumulacija metala u odabranim vrstama voća i lekovitih biljaka / Bioaccumulation of metals in selected types of fruits and medicinal herbs
(Универзитет у Нишу, Природно-математички факултет, 23-06-2015)
Plants accumulate metals from the soil during growth. Environmental polution can lead to increased metal uptake into the body through food. Therefore, plants have medicinal properties but also can have toxic effects on ...
Proučavanje efekta pH na strukturu, boju i spektralne karakteristike cijanidina i cijanidin 3-0-ß-glukopiranozida i ispitivanje njihove interakcije sa modelima lipidnih membrana / The investigation og pH effects on the structure, colour and spectral characteristics of cyanidin and cyanidin 3-0-ß-glucopyranoside and the examination of their interactions with lipid model membranes.
(Универзитет у Нишу, Природно-математички факултет, 16-03-2015)
The relationships between structure, spectral
characteristics, and colour of the aglycone moiety of
cyanidin and its 3-glucosidic substitution in cyanidin 3-O-
β-glucopyranoside were studied as a function of pH, using
a ...
