Efficiency and power upgrade at the aged lignite-fired power plant by flue gas waste heat utilization: High pressure versus low pressure economizer installation
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
A substantial potential exists for the recovery of flue gas waste heat at aged coal-fired power plants. High and low pressure economizers (HPE, LPE) can be applied for this purpose. Two cases of the feedwater supply to the ...
Strain field measurements of glass ionomer cement
(Institut za ispitivanje materijala, Beograd, 2019)
Extensive evolution of glass ionomer cements (GIC) has marked a significant shift in the practice of luting indirect dental restorations limiting the use of zinc-phosphate and zinc-polycarboxylate cements to a few indications. ...

Possibilities for wider investment in solar energy implementation
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Installing of new solar capacities for electricity production has slowed down worldwide. To explore this trend, to assess opportunities for implementing solar potential, and to determine whether wider investment in solar ...
Numerical analysis of fatigue crack growth of hip implant
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Fatigue crack growth in hip implant has been analysed using the extended finite element method. Toward this aim, the three-dimensional finite element model is created and used in ABAQUS and Morfeo/crack add-in for ABAQUS ...
