Measurements are presented of inclusive charm and beauty cross sections in e(+)p collisions at HERA for values of photon virtuality 12 <= Q(2) = 60 GeV2 and of the Bjorken scaling variable 0.0002 <= x <= 0.005. The fractions of events containing charm and beauty quarks are determined using a method based on the impact parameter, in the transverse plane, of tracks to the primary vertex, as measured

The immune processes associated with atherogenesis have received considerable attention during recent years. IgG FcRs (FcgammaR) are involved in activating the immune system and in maintaining peripheral tolerance. However, the role of the inhibitory IgG receptor FcgammaRIIB in atherosclerosis has not been defined. Bone marrow cells from FcgammaRIIB-deficient mice and C57BL/6 control mice were tra

Immunoglobulin G (IgG) glycosylation modulates antibody activity and represents a major source of heterogeneity within antibody preparations. Depending on their glycosylation pattern, individual IgG glycovariants present in recombinant antibody preparations may trigger effects ranging from enhanced pro-inflammatory activity to increased anti-inflammatory activity. In contrast, reduction of IgG gly

Protein kinase C (PKC) plays a prominent role in immune signaling, and the paradigms for isoform selective signaling are beginning to be elucidated. Real-time microscopy was combined with molecular and biochemical approaches to demonstrate a role for PKC-epsilon in Fcgamma receptor (FcgammaR)-dependent phagocytosis. RAW 264.7 macrophages were transfected with GFP-conjugated PKC isoforms, and GFP m

Current hemophilia B treatment guidelines recommend routine prophylaxis with factor IX (FIX) replacement products, tailored to maintain plasma activity at levels that will prevent bleeds. However, plasma FIX activity may not be the primary determinant or best indicator of hemostatic efficacy due to its extravascular distribution. FIX replacement therapy has evolved to include extended half-life (E

Stora förändringar och varierad elproduktion har lett till många osäkerheter i elsystemets marknader. Balanseringsverktygen har därmed hamnat i rampljuset med stor inkomstpotential idag och möjligen även långt framöver. Denna rapport visar att det finns stora möjligheter för vätgassystem och batterier att medverka på dessa marknader. En förväntad fördubbling av elproduktion under de kommande 20 årIn order to move away from fossil fuels many governments and industries are focusing their new investments in electricity and alternative fuels such as green hydrogen from electrolyzers using renewable electricity. High investment costs and electricity costs are a hindrance for the future development of a hydrogen economy which can utilize an increasing intermittent power generation. The aim of th

The double compression-expansion engine concepts (DCEE) are split-cycle concepts where the compression, combustion, expansion and gas exchange strokes occur in two or more different cylinders. Previous simulation studies reveal there is a potential to improve brake efficiency with these engine concepts due to improved thermodynamic and mechanical efficiencies.

This thesis discusses the development of Product Category Rule (PCR) for semiconductor Back-End (BE) processes. While Life Cycle Assessment (LCA) are common practice in the industry, there is currently no PCR specifically for BE processes, which creates inconsistent reporting of emissions. This thesis provides a meta-analysis of allocation methodologies for semiconductor packaging. The meta-analys

The reliable operation of nuclear reactors is contingent upon precise control mechanisms for critical components, such as the head circulation pumps. This master thesis investigates an innovative approach to address the ramp-down speed of these pumps during external electrical grid failures by exploring the application of a supercapacitor group. Presently, the existing solution relies on a fly-whe

Gorée is a small island 2 kilometres off the coast of Dakar, Senegal, known as a significant location of the Transatlantic slave trade, and a destination for locals and tourists interested in the subject. From French colonial cultural policies to post-independence national discourses, several buildings on Gorée became places where memory was crystalised and publicised. The most prominent being the

Indoor temperatures in apartment blocks are often indirectly controlled by the outdoor temperature using a feedforward control loop, in which the radiator supply temperature is a function of the outdoor tem- perature. However, this control principle cannot take into account heat gains or losses caused by tenants, electrical appliances, the sun, air leakage, etc., which may result in uneven indoor Indoor temperatures in apartment blocks are often indirectly controlled by the outdoor temperature using a feedforward control loop, in which the radiator supply temperature is a function of the outdoor temperature.
