Numerical analysis of thermal stresses in welded joint made of steels x20 and x22
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Stress calculation of steam pipeline is presented, focused on the welded joint. Numerical calculation was peiformed using the finite element method to obtain stress distribution in the welded joint made while replacing the ...
The Candida rugosa lipase adsorbed onto titania as nano biocatalyst with improved thermostability and reuse potential in aqueous and organic media
(Journal of Molecular Catalysis. B: Enzymatic, 2016)
The immobilization of Candida rugosa lipase by adsorption was performed onto commercial titania powder (Degussa P25). The change of titania particles surface was diagnosed by means of FTIR and FESEM analysis, as well as ...
Synthesis and characterization of high-pressure and high-temperature sphene (CaTiSiO5)
(Springer Verlag, 2014)
Sphene (CaTiSiO5), a calcium titanosilicate ceramic has been prepared from a powder mixture of CaCO3, TiO2 and SiO2 using vibro-milling for homogenization and activation of precursors. During the high-pressure and ...
Effects of process and design parameters on heat management in fixed bed Fischer-Tropsch synthesis reactor
(Korean Institute Chemical Engineers, Seoul, 2018)
A two-dimensional pseudo-homogeneous model of wall-cooled fixed bed Fischer-Tropsch synthesis (FTS) reactor with Co/Re/gamma-Al2O3 catalyst was developed to study the effect of process and design parameters on heat generation ...
Application of experimental design for the optimization of artificial neural network-based water quality model: a case study of dissolved oxygen prediction
(Springer Heidelberg, Heidelberg, 2018)
This paper presents an application of experimental design for the optimization of artificial neural network (ANN) for the prediction of dissolved oxygen (DO) content in the Danube River. The aim of this research was to ...
The novel approach to the biomonitor survey using one- and two-dimensional Kohonen networks
(Springer, Dordrecht, 2015)
To compare the applicability of the leaves of horse chestnut (Aesculus hippocastanum) and linden (Tilia spp.) as biomonitors of trace element concentrations, a coupled approach of one-and two-dimensional Kohonen networks ...
The Prediction of Heavy Metal Permeate Flux in Complexation-Microfiltration Process: Polynomial Neural Network Approach
(Springer International Publishing Ag, Cham, 2019)
Membrane filtration techniques are distinguished among methods for wastewater treatment and fully correspond to the requirements of the green concept of chemistry and production. The limiting factor for greater application ...
Comparative analysis of mathematical models for supercritical extraction simulation from industrially valuable lamiaceae herbs
(Wiley, Hoboken, 2014)
The present study was aimed to compare different mathematical models used to simulate process of supercritical extraction from commercially important Lamiaceae herbs. Supercritical extractions with carbon dioxide from ...
Comparative Study on Cavitation Erosion Resistance of A356 Alloy and A356FA5 Composite
(Springer India, New Delhi, 2017)
In the present study, an aluminum alloy A356 composite with addition of 5 wt% fly ash was synthesized and subjected to the cavitation erosion resistance test in order to find out if this material can be used in conditions ...
