Popular Abstract in Swedish Man har länge känt till att hepatit (leverinflammation) kan överföras som blodburen smitta, t ex vid blodtransfusion eller genom intravenöst narkotikamissbruk. Under de sista decennierna har man identifierat två virus, hepatit B-virus (HBV) och hepatit C-virus (HCV), som visat sig ge upphov till merparten av fall av blodburen hepatit. Fortfarande finns dock en del fall GBV-C/HGV is a blood-borne virus related to the hepatitis C virus. We studied GBV-C/HGV infection in different populations, its transmission, and its association with liver disease. GBV-C/HGV viraemia was detected by PCR in 19/576 blood donors. Donors with normal and elevated ALT levels had similar rates of viraemia (1.6% vs. 4.1%; p = 0.20). Signs of resolved GBV-C/HGV infection (anti-E2 antibodi

This paper presents the study of a mid-sized semi-closed oxy-fuel combustion combined cycle (SCOC-CC) with net power output around 108 MW. The paper describes not only the power balance and the performance of the SCOC-CC, but also the conceptual design of the SCOC turbine and compressor. A model has been built in the commercial heat and mass balance code IPSEpro to estimate the efficiency of semi-

Popular Abstract in Swedish Mineraler fås från både fast och flytande föda. De senaste årtiondena har bordsvattenkonsumtionen ökat, och vattnets kemiska innehåll har alltmer kommit i fokus. Studier visar dessutom att grönsakers mineralinnehåll har minskat, vilket ökar betydelsen av mineralintag från annat håll. Den här doktorsavhandlingen omfattar fyra olika studier. I den första studien undersökMineral elements in drinking water have been in focus for more than a decade, especially as the habit of drinking bottled water has increased, not the least among young people.
