It is well known that particle size has a significant influence on the grid independence behaviour of fluidized bed reactor simulations carried out using the Two Fluid Model (TFM) approach. The general rule of thumb states that the cell size should scale linearly with the particle size so that the...

Several European electricity spot markets use simplified methods such as uniform or zonal pricing. These methods only partly address congestion. Re-dispatch is then necessary to achieve a feasible flow. In the assessment of congestion management methods we address congestion relief in both spot and...

The elaboration of nanostructures including both functional materials and functional morphology is a crucial scientific and technological challenge. In this work diatom frustule replicas mainly consisting of magnesium silicon nitride and nanocrystalline silicon have been obtained by simultaneous...

Raman based gas sensing can be attractive in several industrial applications, due to its multi-gas sensing capabilities and its ability to detect O₂ and N2. In this article, we have built a Raman gas probe, based on low-cost components, which has shown an estimated detection limit of 0.5 % for...

Multi-family apartment buildings have the highest energy demand in Europe, consuming 68% of the total final energy use in buildings in Europe (Economidou et al., 2011). Most of them were built between 1945 and 1980 and are now ready for retrofitting and have a huge energy-saving potential. The...

En helhetlig, stegvis gjennomgang av hvordan man bør gå fram for å få til en ambisiøs energioppgradering. Temaer som inngår i veilederen er tilstandsanalyser, mulighetsstudier, kostnadsanalyse, støtteordninger og beskrivelser som alle bidrar til å nå et vellykket resultat. Andre hensyn som bør...

Background: Despite the high worldwide prevalence and association with other mental disorders and disability, only few studies are available on social phobia in low-income countries. Aims: This study aims to assess the prevalence, socio-demographic correlates and comorbidity of social phobia...
