Finite element analysis of fracture resistance parameters for stationary semi-elliptical surface cracks in high strength steel / Analiza parametara otpornosti na lom metodom konačnih elemenata, kod stacionarnih polueliptičnih prslina u čeliku povišene čvrstoće
(Society for Structural Integrity and Life, Institute for Material Testing, 2015)
This study deals with numerical simulations based on elastic-plastic finite element method for nonlinear stress analyses on pre-cracked tensile specimens with high strength properties. The influence of crack geometry on ...
Influence of Preparation Conditions of Alumina-Based Refractory on the Morphological Parameters of Surface Defects
(Wiley-Blackwell, Hoboken, 2015)
The surface defects on alumina-based refractory arising from thermal shock were studied using image analysis and statistical tools. Alumina-based refractory specimens were prepared by adding a different amount of fibers ...
Physical-mechanical and microstructural properties of alkali-activated fly ash-blast furnace slag blends
(Elsevier Sci Ltd, Oxford, 2015)
This paper investigated physical mechanical and microstructural properties of alkali-activated binders based on blends of fly ash (FA) and blast furnace slag (BFS). FA BFS blends were alkali-activated with sodium silicate ...
Efficiency of sepiolite in broilers diet as uranium adsorbent
(Springer, New York, 2015)
The use of phosphate mineral products in animal nutrition, as a major source of phosphor and calcium, can lead to uranium entering the food chain. The aim of the present study was to determine the protective effect of ...
Structural changes of Ca-alginate beads caused by immobilized yeast cell growth
(Elsevier Science Bv, Amsterdam, 2015)
Structural changes of Ca-alginate bead due to yeast cell loading and the impact on their mechanical properties were studied based on experimental data of cell number density per beads, cell rearrangement within the bead ...
Zn(II) complex with 2-quinolinecarboxaldehyde selenosemicarbazone: synthesis, structure, interaction studies with DNA/HSA, molecular docking and caspase-8 and-9 independent apoptose induction
(Royal Society of Chemistry, 2015)
A new Zn(II)-based potential chemotherapeutic agent was synthesized from the ligand 2-quinolinecarboxaldehyde selenosemicarbazone (Hqasesc). Single crystal X-ray diffraction analysis showed that the Zn(II) complex consists ...
Techno-economic optimization of energy supply of a livestock farm / Tehno-ekonomska optimizacija snabdevanja energijom farmi stoke
(Univerzitet u Nišu, Niš, 2015)
Livestock farming is a significant part of agricultural market in Serbia. However, a descending trend of livestock species has been recorded recently, despite its potential for meat export. Application of new technologies ...
Experimental investigation of heat transfer in three-phase fluidized bed cooling column
(Savez hemijskih inženjera, Beograd, 2015)
A three-phase (gas-liquid-solid) fluidized bed was used to study the heat transfer characteristics of a system consisting of low-density (290 kg/m(3)) spherical particles (2 cm diameter) in a 0.25 m cylindrical column with ...
Impact of sodium sulfate solution on mechanical properties and structure of fly ash based geopolymers
(Springer, Dordrecht, 2015)
In this paper, geopolymers based on two different fly ash samples were exposed to sodium sulfate (Na2SO4) solution (50 g/l) over a period of 365 days. It was found that sulfate solution attack caused a small decrease in ...
