Abstract Operation of the electric arc furnaces (EAFs) is a subject to consider fluctuations in terms its key performance indicators, such as electrical energy consumption (EEC), tap-to-tap time, steel yield, and others. In this paper, more detailed analysis furnace data performed, investigating EEC. It well known that EEC affected by weight type charged scrap, operational delays, tapping tempe...

The blast-furnace process consists of a large number of processes that are physicochemical, thermal and mechanical interconnected processes. In addition to main processes consisting of iron oxides reduction, pig iron and slag melt creation, also realised are fuel combustion, gas flow, charge and melt flow, dissociation and other reactions in the solid and liquid phases. Inputs to the blast-furn...

M. Szega, W. Stanek Silesian University of Technology, Gliwice, Poland L. Blacha Silesian University of Technology, Katowice, Poland The reduction of energy consumption in the blast furnace is still the subject of investigations using mathematical modelling of a blast furnace plant. Theoretical-empirical hybrid models of a blast furnace and its equipment have been presented. This model is built...

OBJECTIVE Unusual clinical course. BACKGROUND "Bath salts" is the street name for a group of recently identified and increasingly abused stimulant synthetic...

We studied the effect of noninvasive radiofrequency-induced hyperthermia on the viability of Aspergillus fumigatus hyphae in vitro. Radiofrequency-induced hyperthermia resulted in significant (>70%, P < 0.0001) hyphal damage in a time and thermal dose-dependent fashion as assessed by XTT [(sodium 2,3,-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino)-carbonyl] (1)-2H-tetrazolium inner salt)...
