Renewable biomass is predicted to have the potential to meet at least a quarter of the world demand for transportation fuel, but to do so both terrestrial lignocellulosic as well as marine algal resources need to be efficiently utilized. In the processes where these biomasses are converted to different types of energy-carriers (for example fuel alcohols e.g. ethanol or butanol) microbial glycoside

Utvecklingen vad gäller halterna av marknära ozon i norra Europa under de senaste drygt tjugo åren karakteriseras av att de högsta halterna har minskat medan de lägsta och medelhöga halterna har ökat. Stigande hemisfäriska bakgrundshalter förklarar troligen de stigande låga till måttliga ozonhalterna.Årsmaximum av glidande 8 timmars ozonmedelhalt minskar på ett statistiskt säkerställt sätt i södra

Popular Abstract in Swedish Avhandlingen tar sin utgångspunkt i frågan om huruvida medeltidens kyrkomålningar kan berätta, och i så fall hur. Syftet är att utforska bildernas förhållande till texter, till betraktaren och det rum där bilderna och betraktaren befinner sig. Till grund för studiet ligger en inventering av medeltida kalkmålningar av Sankt Kristoffer och scener kring Jesu födelse ca 110The subject of the thesis is the narratives in medieval mural paintings in southern Scandinavia c 1100-1530. Its aim is to examine their relationship to texts, to the viewer and to the church space, where the viewer looks at the murals. Two different subjects have been chosen for study: S Christopher and the Nativity of Christ. From the corpus of preserved mural paintings with these subjects in so

The use of a hydrogen-sensitive palladium-metal oxide semiconductor (Pd-MOS) sensor in combination with a membrane for liquid-to-gas transfer for the detection of dissolved hydrogen was investigated. The system was evaluated with known concentrations of dissolved hydrogen in water. The lowest concentration detected with this set-up was 160 nM. The method was applied to monitoring of a laboratory-s

This note is a short discussion on how to present archaeological reconstructions to the public. The author, together with 6 other researchers and authors, comment on means of presenting the past. The author argues that the approach used should be more focussed on sensory and emotional aspects of life in the past.

The present study of spectra of twelve metal-rich cool dwarf stars, carefully selected in order to cover a range of temperatures ( K), is a follow up on Feltzing & Gustafsson (1998) with the aim to understand the apparent over-ionization and anomalous elemental abundances found by them for the K dwarf stars in their sample. Our method of analysis employs synthetic spectra of the full spectrum
