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

Popular Abstract in Swedish Inom forskningen kring rengöring och processhygien är det viktigt att förstå de bakomliggande mekanismerna för depositionen av partiklar och makromolekyler på ytor. Depositionsprocessen kan beskrivas som transporten av partiklar till ytan och den påföljande adhesionen. Om de hydrodynamiska krafterna är tillräckligt starka kan partiklarna åter transporteras bort från ytaIn the research area of cleaning and process hygiene it is important to understand the underlying mechanisms behind the deposition of particles and macromolecules onto surfaces. The deposition process is described as the transport of particles to the surface followed by attachment. If the hydrodynamic forces are strong enough, the particles can be re-entrained. In this work particle deposition wa

This keynote concerns social aspects of information seeking and use in professional life and how these are made explicit in information practices. In particular, the keynote focuses on how professionals’ activities in relation to information artefacts, as well as the artefacts in themselves, are socially constructed in context-bound practices. Arguments in favour of an interest in peoples’ informa

I boken diskuteras framför allt Raoul Wallenberg inför eftervärlden. Ett tema är den svenska inrikespolitiska debatten. Ett annat är det stora internationella intresset för honom som nådde en höjdpunkt under 1980-talet och som har avsatt monument, tv-serier och filmer till hans minne.
