Corrosion resistance of welded pipe in oil wells / Otpornost na koroziju zavarenih cevi u naftnim bušotinama
(Engineering Society for Corrosion, Belgrade, Serbia, 2013)
Steel pipes in oil and gas wells are continuously exposed to the process of corrosion-assisted elevated temperatures and pressures prevailing in the interior of the tube. Corrosion can lead to significant reduction of ...
Strength design calculation of a horizontal pressure vessel / Kontrolni proračun čvrstoće horizontalne posude pod pritiskom
(Society for Structural Integrity and Life, Institute for Material Testing, 2013)
Standards SRPS M.E2.250-262 for calculation of pres-sure vessels have been replaced by SRPS EN 13445-3. This means that calculations of new equipment and check calculations of equipment in service are subjected to ordinance ...
Analysis of metal ion release from biomedical implants
(Association of Metallurgical Engineers of Serbia, 2013)
Metallic biomaterials are commonly used for fixation or replacement of damaged bones in the human body due to their good combination of mechanical properties. The disadvantage of metals as implant materials is their ...
The Galvanostatic Reduction on Modified Platinum Electrode and Determination of Trinitrotoluene in Neutral Solution
(Esg, Belgrade, 2013)
The study of the electrochemical reduction on acetonitrile modified platinum electrode and determination of trinitrotoluene (TNT) in neutral solution by simple galvanostatic technique is presented here. The obtained ...
Biodegradation of starch-graft-polystyrene and starch-graft-poly(methacrylic acid) copolymers in model river water / Biodegradacija kalemljenih kopolimera skroba i polistirena i skroba i poli(metakrilne kiseline) u rečnoj vodi
(Serbian Chemical Soc, Belgrade, 2013)
In this paper, a biodegradation study of grafted copolymers of cornstarch and polystyrene (PS) and cornstarch and poly(methacrylic acid) in model river water is described. These copolymers were obtained in the presence of ...
The influence of different supplements on the probiotic character of fermented whey-based beverage / Uticaj različitih dodataka na probiotski karakter fermentisanog napitka na bazi surutke
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2013)
The aim of this study was the selection of appropriate supplements for the probiotic whey-based beverage production by Lactobacillus johnsonii NRRL B-2178. The analysis of the main effects and their interactions was performed ...
Mathematical modeling of zinc ions biosorption by short hemp fibers / Matematičko modelovanje procesa biosorpcije jona cinka kratkim vlaknima konoplje
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2013)
Waste hemp fibers 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 fibers were chemically modified. The following ...
