ESTIMATION OF THE POSSIBILITY FOR FURTHER APPLICATION OF ETHANOLIC FRACTION OBTAINED DURING ALGINATE PRODUCTION FROM BROWN SEAWEED BIOMASS
(Leskovac : Faculty of Technology, 2023)
The first stage in alginate production is the depigmentation and defatting of brown seaweed biomass using 70% (v/v) ethanol. The obtained ethanolic fraction is discarded from the further production process as a side product. ...
Bio-based products from lactic acid bacteria
(Belgrade : Institute for Biological Research "Siniša Stanković", University of Belgrade, 2019)
Lactic acid bacteria (LAB) are a diverse group of microorganisms with lactic acid
production as a common characteristic. LAB are part of the human diet from the first
days of life, as part of breast milk microbiota, ...
Phoenix spectra for determination of the fundamental stellar parameters
(Institute of Physics, Belgrade, SerbiaAstronomical Observatory Belgrade, Serbia, 2021)
We present a set of calculated spectra for stellar atmospheres. Temperature is
varied from 2500-10000K, log g from 0.5 to 5.5, z from 0.5 to 2.5 and alpha
enhancement -0.2 to +0.8. Our aim is to use these spectra as ...

Effect of Polyhedral Oligo Silsesquioxanes (Poss) Particles on Cavitation Resistance of Hybrid Composite Films
(Belgrade : Association of Metallurgical Engineers of Serbia (AMES), 2019)
The objective of this study is to investigate the influence of the polyhedral oligo silsesquioxanes (POSS) structure on cavitation erosion of hybrid acrylate composite films. Cavitation is used as a method for estimation ...
Corrosion Testing of an Al-Zn-Mg-Cu Alloy After Different Heat Treatment Regimes by the Application of Electrochemical Methods
(Military Technical Institute, 2012)
Abstract: The corrosion tendency in the 7000 series aluminium alloys changes depending on the content of alloying
elements, thermal and thermo-mechanical treatments, etc. An alloy of this type applied in the production ...
Analysis of floating-head heat exchanger bolts failure
(Timisoara, Romania, 2011)
As-received floating-head heat exchanger bolts were broken (BB) and deposite-coated. The aim was to estimate
a cause of their failure. The new bolts of the same material were used as a reference material (reference bolt ...
