Popular Abstract in Swedish När främmande fettlösliga ämnen som miljögifter (ex. PCB och dioxin) hamnar inuti kroppen bearbetas de ofta av det så kallade biotransformations-systemet. När inte levern och njurarna direkt kan utsöndra de främmande molekylerna får enzymer ändra de oönskade ämnenas kemiska sammansättning. Detta görs genom att ändra molekylernas kemiska egenskaper så att de blir vattenlIn vertebrates, studies of the aryl hydrocarbon receptor (AhR) have been of particular interest due to its direct involvement in the toxic effects exerted by several environmental pollutants, such as PCB and dioxin. After binding to the toxic molecule, this receptor initiates transcription of several genes that are part of the biotransformation battery but most notably the cytochrome P450 (CYP) ge

Popular Abstract in Swedish Bakgrunnen for den foreliggende avhandling er et ønske om å utnytte moderne tredimensjonell bildeanalyse for å forbedre undersøkelse og tolkning av synsnervehodets (papillens) form og størrelse (topografi). Synsnervehodet representerer den delen av synsnerven som trer inn i bakre del av øyet gjennom senehinnen (sklera). Den normale synsnerve har ca 1.2 millioner nervetrEvaluation of the optic nerve head topography is one of the most important methods to diagnose and monitor patients with glaucoma. Until recently, optic nerve head topography has most often been judged by either ophthalmoscopy or from optic disc photographs. These methods are subjective and examiners do not have access to absolute measurements of the optic disc size and cup depth. The result of su

There is increasing evidence that fermentation in the large intestine is important for health, and that health-promoting effects are mediated by fermentation products such as butyric and propionic acid. As the formation of carboxylic acids (CAs) from various carbohydrates reaching the colon has been shown to vary, it is of great interest to identify food factors that could be of importance to this

In the Grödinge project pottery was recovered from the five Neolithic sites, totaling c. 280 kg. A selected sample of pottery from four of these sites, i.e. the Eklundshov, Smällan, Kyrktorp and Kvedesta sites, has been studied more closely and also analysed technologically.

I denna antologi diskuteras med fokus på nordiska förhållanden sambandet mellan kristen religion och konstruktionen av manlighet under perioden 1840 till 1940. En central fråga är hur kristna ideal som exempelvis ödmjukhet, mildhet och självförsakelse, vilka i den borgerliga genusdiskursen kommit att knytas till kvinnokönet, inverkade på konstruktionen av kristen manlighet och vilka uttryck detta

Environmental and political concerns, together with new legislations, are pushing for a fuel shift in the power industry and more generally for many thermal applications. Adding to the coming decrease of oil and natural availability (or price increase), it opens avenues for new fuels. Among those, alcohols are strong candidates. In fact, short alcohols are easily produced and stored and require on

Biometric identification is an important security application that requires non-intrusive capture and real-time processing. Security systems based on fingerprints and retina patterns have been widely developed, but can be easily falsified. Recently, identification by vein patterns has been suggested as a promising alternative. In this paper an existing feature extraction algorithm, that has been d
