The corrosion resistances of near equimolar CoCrFeMnNi magnetron-sputtered thin films with different carbon concentrations were examined in 0.05 M HCl and H2SO4. Polarization curves recorded scan rates without reducing the native oxide. results showed that concentration experimental conditions affected electrochemical behaviour mainly Cr transpassive region. At potentials above 850 mV, carbon-c...

This paper explores the provision of adaptive hints based on attainment levels in the context of supporting the development of young adults’ ICT information processing skills. We describe the design of the LIBE VLE, particularly its personalisation and adaptation features, and a User Study undertaken with young adults at a vocational education centre. Using data collected through the LIBE VLE, ...

Contact of concrete with aggressive factors, technological structures, reduces their durability through microstructural changes. This work presents the results research on determining influence post grit chamber sewage and from active sludge in three different environments, i.e., acidic, neutral, alkaline, structure compressive strength concrete. Compressive tests were carried out after 11.5 mo...
