Free vibration of structures composed of rigid bodies and elastic beam segments
(Academic Press Ltd- Elsevier Science Ltd, London, 2015)
Free vibration of structures composed of rigid bodies and elastic beam segments is considered, assuming that the mass centers of rigid bodies are not located on the neutral axes of undeformed elastic beam segments. It is ...
On the problem of a heavy homogeneous ball rolling without slipping over a fixed surface of revolution
(Elsevier Science Inc, New York, 2022)
The paper considers a heavy homogeneous ball rolling without slipping on the outside of a real rough fixed surface of revolution, which is generated by rotating a plane curve around a vertical axis. By applying the Coulomb ...
Chaotic fruit fly optimization algorithm
(Elsevier, Amsterdam, 2015)
Fruit fly optimization algorithm (FOA) is recently presented metaheuristic technique that is inspired by the behavior of fruit flies. This paper improves the standard FOA by introducing the novel parameter integrated with ...
Humidity sensing properties of nanocrystalline pseudobrookite (Fe2TiO5) based thick films
(Elsevier Science Sa, Lausanne, 2018)
Pseudobrookite based nanopowder was obtained by solid state synthesis of starting hematite and anatase nanopowders in the weight ratio 55:45. Structural and morphological properties were analyzed using X-ray diffraction ...
Investigation into the causes of fracture in railway freight car axle
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Railway axles are vital parts of railway. Their failure in the form of dynamic fracture is commonly of disastrous outcomes for railway vehicles. Accordingly, railway axles are designed to be highly reliable, while the ...
Mixed Mg-Co spinel ferrites: Structure, morphology, magnetic and photocatalytic properties
(Elsevier, 2021)
CoxMg1-xFe2O4 (where x was 0.0, 0.1, 0.3, 0.5, 0.7, 0.9 and 1) spinel ferrites were synthesized by the sol-gel combustion method using citric acid as fuel, following the rules of propellant chemistry. Amorphous powders ...
Numerical study of pulverized coal-fired utility boiler over a wide range of operating conditions for in-furnace SO2/NOx reduction
(Pergamon-Elsevier Science Ltd, Oxford, 2016)
Important tasks during pulverized coal-fired utility boiler exploitation are efficient utilization of variable quality fuels, operation in a wide range of loads and emission reduction of pollutants, like oxides of nitrogen ...
Novel amino-functionalized lignin microspheres: High performance biosorbent with enhanced capacity for heavy metal ion removal
(Elsevier, 2020)
Novel highly effective amino-functionalized lignin-based biosorbent in the microsphere geometry (A-LMS) for removal of heavy metal ions, was synthesized via inverse suspension copolymerization of kraft lignin with poly(ethylene ...
DUV fluorescence bioimaging study of the interaction of partially reduced graphene oxide and liver cancer cells
(IOP Publishing Ltd, 2018)
The interaction of partially reduced graphene oxide (prGO) and Huh7.5.1 liver cancer cells was investigated by means of DUV fluorescence bioimaging. The prGO sample was obtained by the reduction (to a certain extent) of ...
Achieving sustainable work of the heat pump with the support of an underground water tank and solar collectors
(Elsevier Science Sa, Lausanne, 2015)
This paper deals with the methodology of sizing a sustainable heating-cooling system, which consists of a heat pump, thermo-solar collectors and underground water tank, as a seasonal thermal energy storage. The methodology ...
