Non-linear frequency response of non-isothermal adsorption controlled by micropore diffusion with variable diffusivity / Nelinearni frekventni odziv neizotermnog adsorpcionog sistema čija je kinetika kontrolisana difuzijom kroz mikropore sa promenljivom difuzivnošću
(Serbian Chemical Society, Belgrade, 2000)
The concept of higher order frequency response functions (FRFs) is used for the analysis of non-linear adsorption kinetics on a particle scale, for the case of non-isothermal micropore diffusion with variable diffusivity. ...
The effect of false-twist texturing parameters on the structure and crimp properties of polyester yarn
(Savez hemijskih inženjera, Beograd, 2017)
In this paper, the effect of false-twist texturing parameters (texturing speed, heater temperature, draw ratio and disc-to-yarn speed ratio (D/Y ratio)) on the structure and crimp properties of polyester yarn has been ...
The extremely high stability of carbofuran pesticide in acidic media / Ekstremno visoka stabilnost pesticida karbofurana u kiseloj sredini
(Faculty of Technology, Novi Sad, 2007)
Environment friendly iron catalysts were applied in the decomposition reactions of some toxic compounds like phenol, methomyl and corbofuran pesticide. The applied catalytic processes belong to photo-Fenton reactions. ...
Effects of substituents on the electronic absorption spectra of 3-N-(4-substituted phenyl)-5-carboxy uracils in different solvents: Part II / Efekat supstituenata na apsorpcione spektre 3-N-(4-supstituisanih fenil)-5-karboksi uracila u različitim rastvaračima - deo II
(Serbian Chemical Society, Belgrade, 2000)
Absorption spectra of some 3-N-(4-substituted phenyl)-5-carboxy uracils, previously determined in twelve solvents, are correlated with substituent sp+ values or by dual substituent parameter correlations involving sI and ...
Immobilization of fish chromatophores for use as a micro-biosensor for biological toxins / Imobilizacija hromatofora riba radi korišćenja kao biosenzor za biološke toksine
(Association of the Chemical Engineers of Serbia, 2003)
Chromatophores isolated from the Siamese fighting fish, Betta splendens, represent a class of living cells that provide a vivid color response to microbial pathogens and environmental toxins. The selection of the most ...
Polymers contamination by heavy metal compounds / Kontaminacija polimera teškim metalima
(Association of Chemical Engineers of Serbia, 2002)
The contamination of important synthetic (surface unmodified) polymers by various heavy metal compounds (such as copper, manganese and lead) in aqueous medium was investigated in this study. The influence of the pH of the ...
FEM simulation of welded joint geometry influence on fatigue crack growth resistance
(1st Virtual European Conference on Fracture - Vecf1, 2020)
Fatigue behaviour of welded joints is investigated, in terms of welded joint geometry and the fatigue crack position. It is based on previous work which involved numerical simulation of fatigue crack growth in a welded ...
Heterogeneous base-catalyzed methanolysis of vegetable oils: State of art / Heterogena bazno katalizovana metanoliza biljnih ulja - presek stanja
(Association of Chemical Engineers of Serbia, 2010)
Today, homogeneous base-catalyzed methanolysis is the most frequently used method for industrial biodiesel production. High requirements for the quality of the feedstocks and the problems related to the huge amount of ...
GEOSPATIAL MAPPING OF ECOLOGICAL RISK FROM POTENTIALLY TOXIC ELEMENTS IN SOIL IN THE PANNONIAN-CARPATHIAN BORDER AREA SOUTH OF THE DANUBE
(Carpathian Association of Environment and Earth Sciences, 2022)
This study collected agricultural surface soil samples from 200 sites in the district of Braničevo, located in the Carpathian Mountains – Pannonian Basin south of the Danube River (Serbia). The main objective was to determine ...
Sepiolite from Serbian deposits as an industrial mineral / Sepiolit iz ležišta u Srbiji kao industrijski mineral
(Savez inženjera i tehničara Srbije, Beograd, 2015)
Long-termed geological exploration of sepiolite in Serbia has proved that there exist two structuralmorphological types of sepiolite deposits: the vein type - in ultrabasic rocks, associated with vein magnesite deposits ...
