Fuel cells are electrochemical devices that convert chemical energy into electricity. Solid oxide fuel cells (SOFCs) are a particularly interesting type because they can reform hydrocarbon fuels directly within the cell, which are possible thanks to their high operating temperature. The purpose of this study is to develop an anode-supported SOFC theoretical model, to enhance the understanding of t

I boken diskuteras allergins tillblivelse, hur föräldrar upptäcker och konstaterar att deras barn lider av allergi. Likaså hur man tror sig kunna undvika allergi eller förebygga den. Och vilka platser och miljöer är viktiga för allergikerna, och inte minst: Vad betyder allergisjukdom för den enskilda människan i det dagliga livet? Även omgivningens syn på de allergiska barnet belyses.

Popular Abstract in Swedish Populariteten av karttjänster, t.ex. på Internet, ökar ständigt. Detta beror till stor del på en hela tiden förbättrad teknik och ett ökande antal idéer för kartapplikationer. Exempel på kartapplikationer är: positioneringstjänster, navigationstjänster, och tjänster för att söka efter, titta på och ladda ner geografiska data och kartor. Kartorna i dessa tjänster skapas The research presented in this thesis has focused on methods for improving the legibility and usability of maps in real-time map services. The aim has been threefold: to create methods to increase the cartographic quality of maps in map services, to develop methods to measure the legibility, as perceived by the user, and to evaluate the quality of maps. Map services are becoming increasingly commo

On a recent trip to Venice, an advertising hoarding was spotted which read ‘Think with your senses, feel with your mind!’ This reminded the authors to think about the relationship between cognitive aspects of individual and organizational knowledge on one hand and feelings/emotions – the affective domain – on the other. When using knowledge within an organizational context, an individual cannot di

Context: With new astronomical infrared spectrographs the demands of accurate atomic data in the infrared have increased. In this region there is a large amount of parity-forbidden lines, which are of importance in diagnostics of low-density astrophysical plasmas. Aims: We present improved, experimentally determined, energy levels for the lowest even LS terms of Fe ii, Ti ii and Cr ii, along with

This document contains the description of relevant material for a compendium of methods & tools, best practices, case studies, reference and guidance material for change & transition available in the safety related industry. The findings from this study cover about 40 different methods, tools, case studies, etc. from the nuclear, petroleum, chemical/technical and maritime domains. The coll

A number of numerical simulations of rack storage fires have been carried out, with various fuel types and burner outputs. Both the standard buoyancy-modified k - turbulence model and a recently developed turbulence model which significantly improves the consideration of the buoyancy effect on turbulence and turbulent transport, were used to study the turbulence of the buoyant flow. The flamelet c

This study collected 257 vocalisations from three domestic cats when they were watching birds through the window. The sounds were subdivided into the types chatter, chirp, tweet and tweedle, and analysed for duration and F0. Variation was found within and between these types as well as within and between the three cats in both duration and F0. A tentative taxonomy of prey-observing cat vocalisatio

The influence of finite length gradient pulses on NMR diffusion experiments on liquids confined to diffuse between two parallel planes is investigated. It is experimentally verified that the pore size decreases when determined using finite gradient pulses if the results are analyzed within the short gradient pulse approximation. The results are analyzed using the matrix formulation. The observed m
