To produce fuel from gasified biomass is a way to manufacture carbon dioxide neutral fuels for transport purposes. The biomass is gasified by heat in a gasification unit, with or without nitrogen, and the resulting mixture consist of hydrogen, carbon dioxide, carbon monoxide, methane, steam, higher hydrocarbons in low concentration and tars. The gas will also contain nitrogen, argon, ammonia, hydr

Pay-What-You-Want (PWYW) pricing schemes are popular in certain industries and not others. We model the seller's choice of pricing scheme under various market structures assuming consumers share their surplus. We show that the profitability and popularity of PWYW depend not only on consumers' preferences, but also on market structure, product characteristics and sellers' strategies. While there is

Språkets speglingar är en hyllning till språket och den humanistiska traditionen. Den är tillägnad professor Birger Bergh som lämnade lärostolen i latin i juni 2000. 80 svenska och utländska forskare medverkar och ger tillsammans ett tvärsnitt av pågående forskning kring språket från studier över den kränkte Akilles vrede och synen på naturen i antiken till Selma Lagerlöfs högläsningskvällar och V

The influence of phase structure on the extraction recovery of monoolein from monoolein-water systems by supercritical carbon dioxide was investigated. Two monoolein-water mi tures at concentrations of 9 wt% water and 18 wt% water, respectively, were studied. H-2-NMR was used to monitor changes of the phase structures in supercritical conditions. The results showed that the phase structure and the

The kinetics and mechanism for substitution reactions on tetraaquapalladium(II) by an extended series of thioethers, a great number of carboxylic acids, and olefins have been studied by use of UV-VIS, stopped-flow, and high-pressure stopped-flow spectrophotometry and NMR spectroscopy. Second-order rate constants k and activation parameters (activation enthalpies, entropies, and volumes) for format

Various occupational exposures have been monitored by chromosomal aberrations, sister chromatid exchanges and micronuclei in peripheral blood lymphocytes. During the last decade, epidemiological studies have evaluated whether any of these markers foreshadows cancer risk. Results from Nordic, Italian and Czech cohorts support an approximately twofold cancer risk among subjects with high frequencies

Lunds universitet deltog under 2008-2009 i två europeiska benchmarkingprojekt om eLärande, EADTU:s E-xcellence+ och ESMU:s Benchmarking eLearning exercise2009. Under 2009-2010 deltar LU dessutom i det internationella projektet The First dual-mode distance learning benchmarking club. Erfarenheterna från deltagande i projekten kommer att presenteras i en rapport under hösten 2010. I samband med pro

Popular Abstract in Swedish Syftet med avhandlingen är att kritiskt undersöka hur högt fettintag hänger samman med övriga kostvanor, livsstilsvanor och socioekonomisk status och om högt fettintag påverkar risken att insjukna i postmenopausal bröstcancer. Intag av fett och sambandet med hälsa är ett kontroversiellt område. Trots att det länge funnits officiella rekommendationer om hur mycket fett The aim was to explore the inherent meaning of total fat and to examine the associations between relative fat intake and postmenopausal breast cancer. Furthermore, the impacts of the alterations in dietary assessment routines are discussed. This thesis uses data from the Malmö Diet and Cancer study, a prospective cohort study. Information on dietary habits, lifestyle, and socioeconomic factors wa
