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 ...
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 ...
Preparation and Characterization of Silver-Loaded Hemp Fibers with Antimicrobial Activity
(Korean Fiber Soc, Seoul, 2014)
The objective of this research was to impart antimicrobial properties to hemp fibers by incorporation of silver ions in hemp fibers by chemisorption. Sorption properties of hemp fibers were improved by non-selective oxidation ...
Synthesis and characterization of new refractory coatings based on talc, cordierite, zircon and mullite fillers for lost foam casting process
(Polska Akad Nauk, Polish Acad Sciences, Inst Metall & Mater Sci Pas, Warszawa, 2014)
Refractory coatings based on different refractory fillers (talc, cordierite, zircon and mullite) for application in Lost Foam casting process were investigated. Design and optimization of the coatings composition with ...
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 ...
Influence of Chemically Modified Short Hemp Fiber Structure on Biosorption Process of Zn2+ Ions from Waste Water
(Korean Fiber Soc, Seoul, 2014)
Short hemp fibers, acquired as a waste from textile industry, were used as an efficient biosorbent for removal of zinc ions from polluted water. In order to obtain the material with better sorption properties, short hemp ...
Compost of Aquatic Weed Myriophyllum spicatum as Low-Cost Biosorbent for Selected Heavy Metal Ions
(Springer International Publishing Ag, Cham, 2014)
Aquatic weed Myriophyllum spicatum L. is one of the most invasive water plants known. In many countries, it is usually harvested and landfilled, where aerobic and anaerobic decomposition takes place. In this research, the ...
Removal of Cu(II) from aqueous solutions by using fluidized zeolite A beads: Hydrodynamic and sorption studies
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
This study investigated potentials of fluidized bed systems with zeolite A beads for removal of heavy metal ions from aqueous solutions. Two commercial zeolite bead fractions (0.7 and 2.2 mm in diameter) were used, while ...
Surrounding gate long channel nanowire MOSFET modelling-extended analysis
(IOP Publishing Ltd, Bristol, 2014)
Based on the approximate solution of Poisson's equation in the case of a p-doped silicon body, an improved current-voltage characteristic model of long-channel cylindrical surrounding-gate Si nanowire MOSFET is proposed. ...
Diagnostic spectroscopic and computer-aided evaluation of malignancy from UV/VIS spectra of clear pleural effusions
(Elsevier, Amsterdam, 2014)
The automated, computer-aided method for differentiation and classification of malignant (M) from benign (B) cases, by analyzing the UV/VIS spectra of pleural effusions is described. It was shown that by two independent ...
