Bacterial surface-associated plasmin formation is believed to contribute to invasion, although the underlying molecular mechanisms are poorly understood. To define the components necessary for plasmin generation on group A streptococci we used strain AP53 which exposes an M-like protein ("PAM") that contains a plasminogen-binding sequence with two 13-amino acid residues long tandem repeats (a1 and

Literature surveys, limited to the sensor technologies applicable for the functionalities of relevance for the “Safe Speed” and “Safe Distance” concept, were conducted on recent and undergoing development in the area of sensor technology. Various alternatives of combinations of sensors can serve for building the prototype for the Safe Speed and Safe Distance concept. However, one sensor alone can

During the establishmen of an NGO Maritime Rescue Service (MRS)in the Lake Albert region in Uganda, the intelligence information management (IM) needs of the operation cere compared with earlier IM experiences of a combined peace keeping mission. This paper describes the MRS oparation IM needs. Furthermore, the Joint Command and Control Information Exchange Data Model (JC3IEDM) is introducea as th

Popular Abstract in Swedish Jonstråleanalys är ett fält inom tillämpad fysik vars utövare sysselsätter sig med bestrålning av olika föremål med joniserande strålning från partikelacceleratorer. Fysiker och kemister observerade i början av nittonhundratalet att joniserande strålning såsom alfapartiklar från radioaktiva källor ger upphov till olika sorters strålning när den växelverkar med materiThe overall goal of this thesis is to test new detector technologies and data acquisition systems, for use in Ion Beam Analysis IBA. This is intended to complement the existing setup, which is routinely used at Lund Ion beam Analysis Facility LIBAF. Proton induced X-ray emission is a well-known method for trace element analysis of heavier elements, but trace element analysis of elements below alum

Synthesis of operating procedures for batch plants involves systematic generation of step by step instructions which the operator can implement to manage the batch plant safely and optimally. This is a labor and knowledgeintensive task. It often takes weeks of effort by experts to prepare a clear and error free set of instructions even for a moderately complex plant. If this process is automated,

The aim of this study was to systematically evaluate the potential of static MR Imaging in congenital heart disease. As low field equlpment was first avaliable, and contlnues to be used, the experienee with this type of imager is reported. Accurate parameter setting is of the greatest importance for efficient cardiac scanning. In small experimental animals, ECG gating and number of excitations we

Denna uppsats markerar ett nytt och kompletterande spår i Certecs verksamhet: att i datormodellens form simulera mänskligt lärande. Förhoppningen är att det därigenom skall komma fram nya idéer både om lärande och om pedagogiska möjligheter kring hur man kan stötta lärandet. Certec kommer att medverka till att den nya kunskapen i första hand skall komma människor med inlärningssvårigheter till god

Popular Abstract in Swedish Markfosfor och mångfald av växter i svenska gräsmarker – en populärvetenskaplig sammanfattning Olika typer av gräsmarkshabitat innehåller en stor och viktig del av mångfalden av växtarter i Skandinavien och i norra Europa. En stor del av arterna är knutna till kulturlandskapet och des's äldre hävdformer. Förändringar i användning och skötsel av gräsmarkerna under detThe semi-natural grassland habitats contain an important part of the plant diversity in Europe. Changes in farming practices have lead to drastic decreases in plant species richness. The aim of the present thesis is to contribute to the knowledge about mechanisms governing the plant species richness in grasslands with emphasis on soil nutrients. Most species rich grasslands are found on soils with
