The Swedish hydropower industry operates a large number of power plants and dams geographically spread over the country. The level of safety of a specific dam is to a large extent determined during the design and construction phases that in the case of Swedish hydropower plants took place several decades ago. Condition monitoring of concrete dams, or hydropower concrete structures, has until recen

I antologibidraget visas att lärande, eller kanske snarare deltagande i olika former av utbildning, rättfärdigas på olika sätt beroende på om de som utbildas är barn eller vuxna. Rättfärdigandet sker genom retoriska konstruktioner av samhället som närmast kan ses som motsatser: barnens skolgång rättfärdigas genom att samhället konstrueras som en, åtminstone värdemässig, konstant; vuxnas deltagande

In this paper we address intra-domain routing optimiza- tion issues in Internet networks related to a combination of Open Shortest Path First (OSPF) and Multi Protocol La- bel Switching (MPLS) routing protocols. Since MPLS can be combined with any routing protocol there has appeared an idea of coupling IP streams routed via the OSPF pro- tocol and MPLS Label Switched Paths (LSPs) in the same netwo

Popular Abstract in Swedish Vi blir alla förkylda, får influensa eller magsjuka någon gång då och då. Smittsamma sjukdomar orsakas av patogener, d.v.s. virus, bakterier eller andra typer av parasiter. De flesta patogener som vi kommer i kontakt med tas om hand av vårt effektiva immunförsvar och vi märker i bästa fall inte av smittan. Huruvida vi blir sjuka eller inte när vi utsätts för smitta, berThe Major Histocompatibility Complex (Mhc) genes are crucial for the recognition of self and non-self peptides by the immune defence system. They are extremely variable in most studied vertebrate species. I have studied the extent and the importance of Mhc variation in Atlantic salmon (Salmo salar), mainly from the Baltic Sea. Levels of Mhc heterozygosity in hatchery populations of salmon were bet

Popular Abstract in Swedish Det mesta av det genetiska materialet i en eukaryot cell finns samlat till kärnan och är organiserat i kromosomer. Varje gång en cell delas kopieras kromosomerna så att de båda resulterande cellerna får ett bibehållet kromosomantal. Den mekanism som styr denna replikeringsprocess förmår dock inte kopiera de yttersta kromosomändarna, vilket resulterar i att dessa blir koTelomeres are specialized complexes of DNA and proteins that cap and confer stability to the ends of eukaryotic chromosomes. The telomeric DNA of most eukaryotes is composed of tandemly arranged short repeats. Within the budding yeasts these repeats are diverged in length as well as in nucleotide composition. However, they contain a sequence resembling the consensus binding sequence of the major t

Four different non-nuclear industries have been investigated regarding the presence of radioactive elements, with the focus on natural radioactivity. The aim of the studies was to investigate the flow of radionuclides in the processes and/or to estimate doses to exposed workers. The first industry investigated was phosphate processing in the manufacture of dicalcium phosphate (DCP), which is used

Thermographic phosphors can be robust temperature remote sensors. The accuracy of the temperature measured by the phosphor is highly dependent on the quality of the phosphor calibration used. Conventionally, thermographic phosphors are calibrated by measuring a series of decay curves at known stable oven temperatures. The process is then repeated covering the thermal sensitivity range of the phosp
