factors which affect the ...
Inflatorni kosmološki modeli sa tahionskim i radionskim poljima
(Универзитет у Нишу, Природно-математички факултет, 15-06-2017)
A popular class of the inflationary cosmological models is based
on an introduction of a scalar field with nonstandard tachyonic
Lagrangian of the Dirac-Born-Infeld (DBI) type. A potentially
fundamental role of the ...

(Универзитет у Нишу, Природно-математички факултет, 16-06-2017)
In this thesis, we analyzed some of the coherent effects – electromagnetically
induced transparency and spontaneously generated coherence – that can
appear in the interaction of the confined hydrogen atom with laser ...
Sulfatima i fosfatima modifikovan ZrO[sub]2 kao katalizator u izabranim industrijski značajnim petrohemijskim procesima
(Универзитет у Нишу, Природно-математички факултет, 03-10-2017)
New rules connected with gasoline have banned many additives, so it is
becoming increasingly difficult to maintain a high octane value of the fuel
while simultaneously respecting the imposed limitations. Thus the ...

Majorizacione relacije i stohastički operatori na diskretnim Lebegovim prostorima
(Универзитет у Нишу, Природно-математички факултет, 23-03-2017)
In this dissertation, notions of weak majorization and weak
supermajorization on descrete Lebesgue spaces are introduced, using
doubly substochastic and superstochastic operators. We generalize
very important results ...
