Sustainable management of Danube renewable resources in the region of Iron Gate Djerdap 1, 2 and 3 case study
(Emerald Group Publishing Ltd, Bingley, 2017)
Purpose - The purpose of this paper is to analyze sustainability of the constructed projects (Djerdap 1 and 2) and feasibility of the planned ones (Djerdap 3) on the river Danube in the region of Iron Gate, with multi-criteria ...
Short history of biomaterials used in hip arthroplasty and their modern evolution
(Springer International Publishing, 2017)
The hip joint is one of the largest joints in the body and is a major weight-bearing joint. The function of the hip is to withstand body weight during standing and walking; during single leg stance the hip joint must carry ...
Experimental determination of brittle fracturing appearance during static indentation of materials based on stone
(Springer Heidelberg, 2017)
During micro cutting process, the presence of both ductile and brittle mode is observed. The appearance of one or the other, or the value of critical penetration depth, when transition is happening, depends on the material ...
Two-dimensional numerical analysis of active flow control by steady blowing along foil suction side by different urans turbulence models
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
The effects of active separation control by steady blowing jets were investigated numerically on three different examples: subsonic flow past Aerospatiale A airfoil at 13 degrees angle-of-attack, transonic flow past NACA ...
Numerical assessment of stress intensity factors at tips of multi-site cracks in unstiffened panel
(Institut za ispitivanje materijala, Beograd, 2017)
The aim of this paper is to establish and demonstrate diverse capacity and performances of different numerical methods for calculating stress intensity factors' (SIFs) histories versus crack length for problems involving ...
Characterizing the Mechanical Properties of Fused Deposition Modelling Natural Fiber Recycled Polypropylene Composites
(MDPI, Basel, 2017)
The objective of this investigation was to characterize the performance of natural fiber reinforced polypropylene composites in fused deposition modelling (FDM). Composite filaments comprising of pre-consumer recycled ...
Utilization of waste ceramics and roof tiles for radionuclide sorption
(Inst Chemical Engineers, Rugby, 2017)
The possible utilization of waste ceramic (CT) and roof tiles (RT), as sorbents for liquid radioactive waste (LRW) treatment, was investigated. Following the European directives on waste and politics of saving natural raw ...
Primarna i sekundarna regulacija snage na blokovima tent B1 i B2 promenom protoka napojne vode kroz dodatni ekonomajzer
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd i Društvo termičara Srbije, Beograd, 2017)
Na parnim kotlovima blokova B1 i B2 Termoelektrane 'Nikola Tesla B' je tokom prve faze kapitalnog remonta ugrađen dodatni ekonomajzer, sledstveno 2012. i 2016. godine. Dodatni ekonomajzer se napaja vodom pomoću posebne ...
Measurement of thermal emission during cutting of materials using abrasive water jet
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
This article deals with measurement of the thermal gradient on material during abrasive water jet cutting. The temperature was measured by thermocamera before the technological process started, during the abrasive water ...
Stringer effect on fatigue crack propagation in A2024-T351 aluminum alloy welded joint
(Elsevier Sci Ltd, Oxford, 2017)
This paper describes fatigue crack growth in a friction stir welded T joints made of aluminum alloy A2024-T351 under three point bending loads. For this purpose, three dimensional homogeneous isotropic model is used to ...
