NOx emission reduction by staged combustion in grate combustion of biomass fuels and fuel mixtures
(Elsevier Sci Ltd, Oxford, 2012)
NOx and N2O emissions have been investigated for different pelletized biomass fuels and fuel mixtures thereof both with and without air staging in a grate fired multi-fuel reactor. The fuels investigated are wood, demolition ...
Brachistochrone with limited reaction of constraint in an arbitrary force field
(Springer, Dordrecht, 2012)
The paper considers brachistochronic motion of a particle along a curve y=y(x) in an arbitrary force field in the vertical plane of Cartesian coordinate system. The curve is treated as a bilateral or unilateral constraint ...
Experimental determination of fouling factor on plate heat exchangers in district heating system
(Elsevier Science Sa, Lausanne, 2012)
This paper presents the results of experimental research on 8 plate heat exchangers. Their purpose is to heat water for radiator heating system and domestic hot water. Measurements were carried out in 4 substations in ...
Experimental evaluation of desuperheating and oil cooling process through liquid injection in two-staged ammonia refrigeration systems with screw compressors
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
This paper examines the problem of achieving desuperheating through liquid injection in two-staged refrigeration systems based on screw compressors. The oil cooling process by refrigerant injection is also included. The ...
Techno-economic optimization of plant for raw ethanol production based on experimental data
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
This paper concerns techno-economic optimization of the production process of raw ethanol in a continuous distillation column as a part of the plant for production of rectified alcohol. Optimization was performed in order ...
Symmetric spaces approach to some fixed point results
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
In this paper we present a simple and unified approach to the fixed point results on cone symmetric spaces and metric type spaces based on symmetric spaces fixed point theory. We also give a new characterization of semi-metric ...
Bond strength of restorative materials to hydroxyapatite inserts and dimensional changes of insert-containing restorations during polymerization
(Elsevier Sci Ltd, Oxford, 2015)
Objective. To determine the shear bond strength (SBS) between synthetic controlled porous hydroxyapatite (HAP) inserts and restorative materials and dimensional changes of insert-containing restorations during curing. ...
Some coupled coincidence and common fixed point results for a hybrid pair of mappings in 0-complete partial metric spaces
(Springer International Publishing Ag, Cham, 2013)
In this paper we extend some coupled coincidence and common fixed point theorems for a hybrid pair of mappings obtained by Abbas et al. (Fixed Point Theory Appl. 2012:4, 2012, doi:10.1186/1687-1812-2012-4) from the complete ...
Tensile properties of ADI material in water and gaseous environments
(Elsevier Science Inc, New York, 2015)
Austempered ductile iron (ADI) is an advanced type of heat treated ductile iron, having comparable mechanical properties as forged steels. However, it was found that in contact with water the mechanical properties of ...
