On macroscopic quantum phenomena in biomolecules and cells: From levinthal to hopfield
(Hindawi Publishing Corporation, 2014)
In the context of the macroscopic quantum phenomena of the second kind, we hereby seek for a solution-in-principle of the long standing problem of the polymer folding, which was considered by Levinthal as (semi)classically ...
Effect of welded joint imperfection on the integrity of pipe elbows subjected to internal pressure
(University of Osijek, Tech Fac, Slavonski Brod, 2013)
Since local defects reduce the load-carrying capacity and deformation ability of a piping system, an analysis is undertaken to quantify the influence of weld defects on integrity of the pipe elbows subjected to internal ...
Quality attributes of a fermented whey-based beverage enriched with milk and a probiotic strain
(Royal Society of Chemistry, 2014)
Beverages produced by fermentation of whey have significantly lower viscosity, milder flavour and less viability of probiotic microorganisms compared to those obtained by fermentation of milk. Therefore, it is necessary ...
Uticaj parametara sinteze na mehanička svojstva nanokompozita PMMAmakseni / Influence of synthesis parameters on mechanical properties of nanocomposite PMMA-MXene
(Savez inženjera i tehničara Srbije, Beograd, 2021)
U ovom radu je ispitan uticaj rastvarača i načina procesiranja ojačanja na mehanička svojstva nanokompozita poli-(metil metakrilat) PMMA-Ti3C2Tx makseni. Korišćen je maseni udeo ojačanja 1% i dve vrste rastvarača za pripremu ...
Hydrometallurgical recovery of tin and lead from waste printed circuit boards (wpcbs): limitations and opportunities
(Croatian Metallurgical Soc, Zagreb, 2016)
In this paper, possibility for selective Pb and Sn recovery, using three different solutions of NaOH, HCl and HNO3, from WPCBs containing low concentrations of Pb and Sn is presented. According to obtained results, over ...
Heat generation during plunge stage in friction stir welding
(Vinca Institute of Nuclear Sciences, 2013)
This paper deals with the heat generation in the Al alloy Al2024-T3 plate under different rotating speeds and plunge speeds during the plunge stage of friction stir welding. A 3-D finite element model is developed in the ...
Influence of whey proteins addition on mechanical stability of biopolymer beads with immobilized probiotics / Uticaj dodatka proteina surutke na mehaničku stabilnost biopolimernih nosača sa imobilisanim probioticima
(Savez inženjera i tehničara Srbije, Beograd, 2015)
Biopolymer carriers are widely used for immobilization of the bioactive compounds and different type of the cells. The aim of this study was to analyze influence of whey proteins addition on mechanical strength of Ca-alginate ...
Analysis of the tool plunge in friction stir welding comparison of aluminum alloys 2024 t3 and 2024 t351
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
Temperature, plastic strain and heat generation during the plunge stage of the friction stir welding of high-strength aluminum alloys 2024 T3 and 2024 T351 are considered in this work. The plunging of the tool into the ...
Cleavage Fracture of the Air Cooled Medium Carbon Microalloyed Forging Steels with Heterogeneous Microstructures
(MDPI, 2022)
Cleavage fracture of the V and Ti-V microalloyed forging steels was investigated by the four-point bending testing of the notched specimens of Griffith-Owen’s type at −196◦ C, in conjunction with the finite element analysis ...
Non-woven sorbent based on recycled jute fibers for efficient oil spill clean-up: From production to biodegradation
(Elsevier B.V., 2023)
Loose assemblies of cellulose fibers could be employed in the clean-up of oil spills, but the difficulty to separate them from the spill after use makes them impractical. In an effort to tackle this issue, a non-woven ...
