Popular Abstract in Swedish Förbränningsmotorer används på flera platser i samhället där energi behöver göras tillgänglig i form av mekaniskt arbete eller elektrisk energi. Den kanske mest kända tillämpningen är som kraftkälla i en personbil. Förbränningsmotorerna har givetvis ett antal fördelar som bidragit till deras popularitet och omfattande användning - lågt pris, kompakthet, driftsäkerhet ocCurrent combustion engines provide excellent performance for vehicle propulsion and power generation. However, recent demands from society ask for higher efficiencies and lower emissions. These requirements are hard to meet with current technology and call for new solutions. Homogeneous Charge Compression Ignition, HCCI, offers a potential to combine high efficiency with very low emissions. It op

Leukotrienes (LTs) and prostaglandins (PGs) are metabolites of arachidonic acid that play major roles in various inflammatory conditions. The release of these mediators, by cells recruited to or present at the site of inflammation, modulate/influence the magnitude of the inflammatory response. A better understanding of eicosanoids and how their receptors trigger intracellular signaling during infl

beta 2-microglobulin (beta 2m) was found to interact with many group A streptococcal strains. The interaction appeared to require multipoint attachment, since monomeric beta 2m in solution showed no binding, whereas both beta 2m monomers bound to liposomes, and beta 2m in aggregates showed affinity for the bacteria. Aggregated HLA antigens (-A, -B and -C) and aggregated beta 2m exhibited the same

This work deals with different types of repair methods for concrete slab on the ground damaged by moisture. Many of the available methods involve some kind of mechanical ventilation of the foundation. The basic principle for all these systems is the same. By establishing air movement through an air-permeable layer below or above the concrete slab, the flowing air can absorb moisture from surroundi

Disentangling the relative importance and potential interactions of selection and genetic drift in driving phenotypic divergence of species is a classical research topic in population genetics and evolutionary biology. Here, we evaluate the role of stochastic and selective forces on population divergence of a colour polymorphism in seven damselfly species of the genus Ischnura, with a particular f

Cytomegalovirus (CMV) is a virus that causes chronic infections in a large set of the population. It may cause severe disease in immunocompromised individuals, is linked to immunosenescence and implied to play an important role in the pathogenesis of cardiovascular diseases and cancer. Modulation of the immune system's abilities to manage the virus represent a highly viable therapeutic option and

Antibodies play a key role in acquired human immunity to Plasmodium falciparum (Pf) malaria and target merozoites to reduce or prevent blood-stage replication and the development of disease. Merozoites present a complex array of antigens to the immune system, and currently, there is only a partial understanding of the targets of protective antibodies and how responses to different antigens are acq

The proposed paper aims at discussing transforming representational programs in recent English-Islamic picture books. As a background, it draws attention to the identity political processes underlying the emerging literature, as stimulated by minority/marginality experiences. In its main section, the paper focuses how the picture books both reproduce and renegotiate Islamic traditional representat

The intestinal immune system has the daunting task of protecting us from pathogenic insults while limiting inflammatory responses against the resident commensal microbiota and providing tolerance to food antigens. This role is particularly impressive when one considers the vast mucosal surface and changing landscape that the intestinal immune system must monitor. In this review, we highlight regio

Combined ATLAS and CMS measurements of the Higgs boson production and decay rates, as well as constraints on its couplings to vector bosons and fermions, are presented. The combination is based on the analysis of five production processes, namely gluon fusion, vector boson fusion, and associated production with a W or a Z boson or a pair of top quarks, and of the six decay modes H → ZZ, W W, γγ, τ

PurposeThe purpose of this paper is to explore if the application of a framework building on organisational learning focusing on organisational processes can increase our understanding of how hybrid organisation develops over time and why they fail to live up to external expectations.Design/methodology/approachThe aim of this study is descriptive and explorative. It is accordingly designed as a qu

Th is article compares the “right to seek and enjoy asylum” enshrined in Art. 14 of the Universal Declaration of Human Rights with the current EU policy developments to “externalize” or “extraterritorialise” migration control and refugee protection. Examining the genesis of Art. 14 during the negotiations of the Universal Declaration, it is argued that while Art. 14 clearly falls short of granting

Mental health problems affect the patients and their families, who may also need therapeutic interventions. Mindfulness interventions have shown beneficial health effects for clinical and healthy populations. A web-based mindfulness intervention was tailored to address families' needs of support and tested in a pilot intervention study. The aim of this study was to explore the participants' experi
