(Institut za ispitivanje materijala, Beograd, 2016)
Results of non-destructive testing of the Kaplan turbine runner manhole welded structure are presented, on the basis of which the repair methodology is defined. During repair, the welding technology for elements of the ...
Uzroci i posledice globalnog zagrevanja
(Energija, ekonomija, ekologija, 2013)
Globalno zagrevanje je jedan od najsloženijih problema današnjice koji se manifestuje povećanjem prosečne temperature zemljine atmosfere od početka dvadesetog veka. Smatra se da je uzrok nastanka usled povećanih emisija ...
Mathematical approach to application of industrial wastes in clay brick production - Part I: Testing and analysis
(Elsevier Sci Ltd, Oxford, 2015)
The objective of this study was to investigate utilization potential of organic and inorganic industrial wastes in clay bricks. Mineral composition of starting heavy clay sample is tested using an X-ray diffractometer. ...
Mathematical approach to application of industrial wastes in clay brick production-Part II: Optimization
(Elsevier Sci Ltd, Oxford, 2015)
The effects of organic and inorganic waste sludges, coal dust, fly and landfill ashes, soybean crust, sawdust, sunflower flakes and their ash addition to representative heavy clay were investigated. Changes introduced to ...
Analysis of Moisture Transfer During the Drying of Clay Tiles with Particular Reference to an Estimation of the Time-Dependent Effective Diffusivity
(Taylor & Francis Inc, Philadelphia, 2014)
The description of the drying process was reduced to the establishment of a series of theoretical and empirical drying models. The complex processes of simultaneous moisture and heat transfer, which are often nonstationary, ...
Mechanical Properties and Microstructure Fractal Analysis of Refractory Bauxite Concrete
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2015)
The surface topography analysis via fractals as a means of explanation of composite materials mechanical and microstructural characteristics has hardly been reported so far. This study proposes a method of fractal analysis ...
