Time-resolved laser spectroscopy has been performed to study the radiative properties of various microscopic systems. Using Laser-Induced Fluorescence (LIF) techniques, natural radiative lifetimes have been studied not only in neutral B, S, Ge, Ce, Pb, and in singly ionized V, Fe, Zr, Mo, La, Ce, Eu, Gd and Yb, but also in doubly ionized La, Ce, Pr, Eu, Er, Gd, Tm, Lu, and W. Data are compared wit
Popular Abstract in Swedish Förmågan hos levande vävnader att läka skador är en basal faktor för överlevnad och utgör grundförutsättningen för all kirurgisk verksamhet. Det finns lokala skillnader beträffande celltyper och tidsförlopp, men mycket talar för att sårläkningsprocessen är principiellt likartad i alla vävnader. Sårläkning indelas i olika faser, varav den första utgöres av en inflammatorWound healing is a multistep process with an initial inflammatory response, followed by synthesis of extracellular matrix components and finalized by a repair phase. One main goal was to determine the impact and adhesive mechanisms of neutrophil recruitment in anastomotic healing in the colon. Passive immunization against CD18 abolished anastomotic accumulation of neutrophils, whereas no effect on
Galiellalactone is a fungal metabolite found in the basidiomycetes Galiella rufa and the unidentified strain A111-95. It has been shown to possess promising activities as an inhibitor of the IL-6 mediated STAT3 signaling in HepG2 cells. Targeting this pathway is very important when it comes to understanding intracellular signaling and also for developing drugs for treating diseases associated with
Popular Abstract in Swedish Hur man undviker att bli trakasserad på flicksländornas vis Tidigare forskningsresultat har visat att hos honor i de flesta djurarter begränsas fortplantningkapacitet av hur mycket tid och energi de kan lägga på sina avkommor. Hos hanar, å andra sidan, begränsas fortplantningskapacitet av hur många honor de kan para sig med. Då kan man dra slutsatsen att hanar ska försThis study has involved investigation of number of populations of the damselfly Ischnura elegans over several years, looking at frequency changes over time, morphological differences between the sexes and the morphs, differences in growth rate and development time, differences in fecundity between the morphs, and genetic differentiation between populations. I. elegans is a small annual damselfly w
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

To improve traffic safety it is important to evaluate the safety of roads and intersections. Today this requires a large amount of manual labor so an automated system using cameras would be very beneficial. We focus on the geometric part of the problem, that is, how to get accurate three-dimensional data from images of a road or an intersection. This is essential in order to correctly identify dif
Popular Abstract in Swedish Byggbranschen står inför stora utmaningar i att möta behovet av nya bostäder samtidigt som renoveringsbehovet av flerbostadshus är stort. Man beskylls ofta för bristande kvalitet och höga kostnader. Industriellt byggande har framförts som en lösning till problemen. I ett projekt på Lunds Universitet har två tillämpningar för industriellt byggande studerats: trähusbygganIndustrialized construction has over the years taken different expressions and gone through different phases depending on where inspiration has come from. In this project, industrialized construction has been studied in two applications: timber house manufacturing and renovation of multi-family houses. In Sweden industrialized production of timber houses is relatively strong in the housing sector
Popular Abstract in Swedish Denna studie fokuserar på reproduktionskostnader och de energetiska taktiker som en reproducerande individ kan utnyttja för att tillfredsställa det ökade behovet av energi och näring under reproduktionen. Reproduktionskostnader har traditionellt definierats som reduktioner av den framtida potentiella produktionen av avkomma, orsakade av en nuvarande reproduktiv investerThis study focuses on various aspects of costs of reproduction and the evolution of energetic breeding tactics. It emphasizes the distinction between demographic costs of reproduction expressed already before current offspring have reached independence (prebreeding costs), and costs expressed only after offspring independence (postbreeding costs). Prebreeding costs have only rarely been appreciate
Reflux of equimolecular amounts 2-aminobenzylamine and isatins in acetic acid produced indolo[3,2-c]quinolin-6-ones in good yields. A proposed mechanism involving initial formation of a spiro compound is given. This isolable intermediate subsequently rearranges via a sequential isocyanate ring opening and a cyclisation process to a urea derivative which finally cyclized to the indolo[3,2-c]quinoli
