The comparison of two methods used to observe a nonlinear system: potentiometry and holography
(Kragujevac, Serbia : Institute for Information Technologies, University of Kragujevac, 2023)
The transition from state I ( characterized by low iodide and iodine concentration) to state II (high iodide and iodine concentration) occurs in a nonlinear Briggs-Rauscher (BR) oscillatory reaction. This transition was ...
The investigation of chitin influence in laser induced deformation of butterfly wings
(Belgrade : Serbian Chemical SocietyBelgrade : Serbian Young Chemists’ Club, 2023)
The investigation of laser beam irradiation on different types of butterfly wings has been done previously by using the holographic method. The deformations due to the use of different laser wavelengths were observed. It ...

Omicron BA.2.75 subvariant of SARS-CoV-2 is expected to have the greatest infectivity compared with the competing BA.2 and BA.5, due to most negative Gibbs energy of binding.
(MDPI, 2022)
Omicron BA.2.75 may become the next globally dominant strain of COVID-19 in 2022. The BA.2.75 sub-variant has acquired more mutations (9) in spike protein and other genes of SARS-CoV-2 than any other variant. Thus, its ...
Possibilities of using sulfur for concrete production and its application
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2015)
Two types of concrete will be shown in this paper. First type of concrete is sulfur concrete, where part of Portland cement was replaced with sulfur. Second type of concrete is selfcompacting concrete, where sulfur replaced ...
