Drying kinetic simulation of clay tiles made from the raw material having less clay fraction
(Trans Tech Publications Ltd, 2014)
In order to describe the internal moisture rate and to take all different mechanisms of moisture movement into account, it is suitable to use effective diffusivity as a measure of moisture rate, irrespectively of the ...
Analysis of current state and integrity evaluation for the supply tank of generation unit 6 of thermal power plant Nikola Tesla ”A”, Obrenovac
(Trans Tech Publications Ltd, 2014)
Stable supply tank, with volume V = 250 m3 and operating pressure p = 1,5 MPa, of generation unit 6 at thermal power plant 'Nikola Tesla A' in Obrenovac, is designed for water-steam working fluid. It was made of steel Č ...
Methodology for reparation of damaged sleeves and welded shield sections of guide vanes at hydropower plant DJERDAP 1
(Trans Tech Publications Ltd, 2014)
Vertical Kaplan turbines, manufactured in Russia and with nominal power of 200 MW, have been installed in 6 hydroelectric generating units at ’Djerdap 1’. During the refurbishment of hydropower plant experimental non-destructive ...
Low cycle fatigue of weldments produced of a high strength low alloyed steel
(Elsevier Science Bv, Amsterdam, 2014)
A quenched and tempered high strength low alloy steel NIONIKRAL 70 for producing welded pressure vessels, where high resistance to fatigue crack propagation and high tolerance of damage are of high importance, has been ...
Drying simulation of shrinkable clay tiles using variable diffusivity model
(Trans Tech Publications Ltd, Stafa-Zurich, 2014)
This paper represents the upgrade of our previous study in which we have presented a model for simulation of the drying kinetic and estimation of the effective moisture diffusivity of clay tiles using a constant diffusivity ...
Phytoremediation of agricultural land contaminated with pesticides
(International Conference "Ecological improvement of devastated locations for sustainable development", Conference Proceedings, 2014)
Pesticides are substances intended for preventing, destroying, suppressing or reducing pests.
They are in use for more than 60 years and they are divided according to purpose, chemical
composition and toxicity category. ...
Changing the structure of concrete after exposure to frost
(Faculty Of Civil Engineering Subotica, 2014)
Concrete testing can be done at micro, mezzo and macro level. Tests at the macro level are the most common and are the ultimate engineering approach, and include testing and comparison of quantities such as commpresive ...
Towards sustainable solutions for fly ash reapplication through mechanical activation
(9th Symposium “Recycling Technologies and Sustainable Development” with international participation, Proceedings, 2014)
The aim of investigation was to find sustainable solution for coal fly ash reapplication by increasing its reactivity through mechano-activation. For obtaining complete insight into activation process an understanding of ...
Advanced Optimization of Heavy Clay Products Quality by Using Artificial Neural Network Mode
(Belgrade : Serbian Ceramic Society, 2014)
The effects of firing temperature (800–1100°C), chemical composition (expressed in terms of
the content of major oxides - SiO2, Al2O3, Fe2O3, CaO, MgO, Na2O, K2O, MnO and
TiO2), as well as several shape formats of ...
NDT and RBI in function of pressure equipment integrity loss
