Popular Abstract in Swedish Avhandlingen undersöker den teoretiska bakgrund och den forskningskontext inom vilken tolkningar av den Nordiska bronsåldern har formats. Avhandlingens teoretiska analys betonar teorier om social praxis och fenomenologiska perspektiv. Analysens syfte är att undersöka hur teorierna kan användas som verktyg för att förstå den dynamiska relationen mellan bronsålderns mater

In vision-based feedback control systems, the time to obtain sensor information is usually non-negligible, and these systems thereby possess fundamentally different timing behavior compared to standard real-time control applications. For many image-based tracking algorithms, however, it is possible to trade-off the computational time versus the accuracy of the produced position/orientation estimat

Encapsulated Haemophilus influenzae is a causative agent of invasive disease, such as meningitis and septicemia. Several interactions exist between H. influenzae and the human host. H. influenzae has been reported to bind IgD in a nonimmune manner, but the responsible protein has not yet been identified. To define the binding site on IgD for H. influenzae, full-length IgD and four chimeric IgDs wi

BACKGROUND: Eosinophils have a typical content of granule-bound, cytotoxic, cationic proteins which may, when released to the external milieu, play roles in diseases such as asthma and parasitic infestation. Therefore, we have investigated possible mechanisms by which their release is regulated in eosinophils. METHODS: The enzyme-linked immunosorbent assay (ELISA) was used to detect released eosin

Efficient policy instruments for reducing the emission of greenhouse gases are essential for the realisation of a successful climate policy. General economic policy instruments have the potential for providing efficient emission reduction as they equalise marginal costs for emission reduction between different actors. They also provide incentives for a great variety of responses such as energy eff

The hormone leptin has been shown to be an afferent signal in a negative-feedback loop regulating body weight, and consequently, the administration of the gene product for the treatment of obesity has recently attracted considerable attention. Leptin is produced by adipocytes in response to increased trigyceride storage, and appears to affect body weight primarily through target cells in the hypot

Resurgence of microbialites and anachronistic facies in the aftermath of Phanerozoic extinction events has hitherto only been documented among the "major five." Based on the classical Silurian carbonate platform strata of Gotland, Sweden, a "minor" biotic event is herein for the first time related to a substantial increase in anachronistic facies. Strata deposited during and shortly after the Lau

There are four peptidyl-proline bonds in the 64-residue protein chymotrypsin inhibitor 2 (CI2), all of which are in the trans conformation in the native structure. The isomerisation of one or more of these peptidyl-proline bonds to the cis conformation in the denatured state gives rise to heterogeneity, leading to both fast and slow-folding species. The refolding of the fast-folding species, which

ydrophobically modified polymers (HM-P) typically behave as thickeners in a wide range of systems. The thickening effect in an aqueous solution of this kind of polymer depends on intermolecular hydrophobic associations and also on chain entanglements if the polymer concentration is significantly above the overlap concentration. In the present investigation a rather short end-capped polymer has bee
