Influence of the alkali treatment on the sorption and dielectric properties of woven jute fabric
(Springer, 2019)
Woven jute fabric was treated with sodium hydroxide solution of different concentrations at room temperature, for different periods of time. After that, jute fabrics with gradually decreased content of hemicelluloses were ...
Fracture assessment of seam and seamless steel pipes by application of the ring-shaped bending specimens
(Elsevier, Amsterdam, 2019)
The topic of this work is analysis of fracture behaviour and resistance of the thin-walled seamless and seam steel pipes, through application of the recently proposed ring-shaped specimen (PRNB - Pipe Ring Notched Bend). ...
Novel protein-repellent and antimicrobial polysaccharide multilayer thin films
(Walter de Gruyter Gmbh, Berlin, 2019)
Nanostructured and bio-active polysaccharide-based thin films were manufactured by means of subsequent spin-coated deposition of a regenerated cellulose (RC) layer and a 2,2,6,6-Tetramethylpiperidine-1-oxyl radical (TEMPO) ...
Image analysis and the finite element method in the characterization of the influence of porosity parameters on the mechanical properties of porous EVA/PMMA polymer blends
(Elsevier Science Bv, Amsterdam, 2019)
Poly(ethylene-co-vinyl acetate) (EVA) and poly(methyl methacrylate) (PMMA) are two incompatible polymers. Compatibilization of EVA/PMMA polymer blends with EVA-g-PMMA decreased the pore diameter and improved the mechanical ...
Bioprocessing of agro-industrial residues into lactic acid and probiotic enriched livestock feed
(Wiley, Hoboken, 2019)
BACKGROUND Growing challenges of resource depletion, food security and environmental protection are putting stress on the development of biorefinery processes for bioprocessing of residues from food and agro-industry into ...
From mycelium to spores: A whole circle of biological potency of mosaic puffball
(Elsevier Science Bv, Amsterdam, 2019)
Methanol extracts of mosaic puffball (Handkea utriformis, Bovistella utriformis, Lycoperdon utriforme, Calvatia utriformis - current name is a subject of debate), from three different stages - mycelium (HUMIC), immature ...
Enhanced Lactic Acid Production by Adaptive Evolution of Lactobacillus paracasei on Agro-industrial Substrate
(Springer, New York, 2019)
The aim of this study was to perform the adaptation of Lactobacillus paracasei NRRL B-4564 to substrate through adaptive evolution in order to ensure intensive substrate utilization and enhanced L (+)-lactic acid (LA) ...
Sorption and dielectric properties of jute woven fabrics: Effect of chemical composition
(Elsevier B.V., 2019)
The jute woven fabric was treated with sodium hydroxide and sodium chlorite under different conditions in order to study the influence of the chemical composition on their sorption and dielectric properties. After the ...
Contributions of impregnated silver nanoparticles to ideality increase of filtration material in human respiratory protection / Doprinos impregnisanih nanočestica srebra porastu idealnosti filtrirajućih sredstava respiratorne zaštite
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
A technical contradiction arises when within a system one parameter improves thus automatically causing another one to worsen. In a situation like this, instead of a usual acceptance of compromise which leads to optimization ...
Abnormalities in the ovule development of the European plum cultivar 'Pozna Plava' in the days following anthesis
(Elsevier Science Bv, Amsterdam, 2019)
Factors such as the stage of ovule maturity and longevity at flowering, when the stigma is able to receive the pollen, are significant in terms of fruit set. Various abnormalities during ovule development can often limit ...
