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

Popular Abstract in Swedish 1900-talet utropades av Ellen Key som ett barnens århundrade. Hon gjorde detta genom att offentliggöra sin dröm om en Framtidens skola i boken med titeln Barnets århundrade. Mot denna bakgrund ställdes frågan om drömmarna blev till verklighet. En av vår tids stora samhällsfrågor gäller relationen mellan individ och samhälle och förhållandet mellan människans personligaThe starting point for this dissertation can be characterised with the question: why don't dreams come true? In 1900, Ellen Key proclaimed the coming hundred years as the children's century. One of the great questions of the time concerned the relation between the individual and the community. Through the years, school curricula became influenced by visions of "reform-pedagogics" (Reformpedagogik)

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. Minerals in drinking water have become more important since minerals in food, especially in vegetables, have decreased substantially the last decades. This thesis includes four different studies. In the first study 20 munic

As Syria’s anti-authoritarian uprising and subsequent civil war have left the country in ruins, the need for understanding the nation’s complex political and cultural realities remains urgent. The second of a two-volume series, Syria from Reform to Revolt: Culture, Society, and Religion draws together closely observed, critical and historicized analyses, giving vital insights into Syrian society t

The increasing demand for solid biofuels, such as primary forest fuels, has highlighted the importance to consider that they, in contrast to fossil fuels are produced in dynamic ecosystems. Environmental effects of changes in ecosystem management policies, positive and negative, are not obvious. To that end, calculations of carbon budgets in single forest stands show that the carbon balance dramat

Popular Abstract in Swedish Det är en utbredd uppfattning att gränserna mellan högkulturen och masskulturen blivit mindre skarpa i vår postmoderna kultur. Den höga litteraturen lånar friskt former, motiv och grepp från masskulturen – och viceversa. Hur skall man tolka den estetiska trafiken mellan kulturella sfärer – höga respektive låga – som länge ansetts oförenliga? Vad består trafiken av och The Struggle for High and Low Culture. Studies in the Late Twentieth Century Novel’s Relationship to Mass Culture and Modernity. It is a widespread opinion that the boundaries between high culture and mass culture have become less defined in our postmodern culture. How is the aesthetic exchange to be interpreted between cultural spheres – high and low respectively – long considered incompatible?

Hållbar utveckling har kommit att bli ett av de mest använda begreppen i vår tid. Att minska den globala fattigdomen och uppnå de globala utvecklingsmålen borde vara centralt i en diskussion om hållbar utveckling. Ekonomisk tillväxt som lyfter människor ur fattigdom är inte bara ekonomiskt och socialt hållbart utan även avgörande för långsiktig miljömässig förbättring. Under senare tid har emeller

This doctoral thesis examines the driving forces of product innovations in the Swedish manufacturing industry during the period 1970-2007. Specifically it examines whether and how innovations have been the creative response to positive factors, such as new opportunities and obstacles related to their exploitation, and negative factors, such as economic, environmental and organizational problems. T

Many contact operations in robotics require accurate positioning, which is made difficult by the presence of rapidly varying interaction forces and compliances in gear boxes and links. In order to compensate for such effects, rapid feedback from the measured tool position in several degrees of freedom is needed. This paper presents a dynamic visual tracking technique based directly on intensity me

The main objective of this thesis was to gain further insight into the relationship between the exposed surfaces and the functional properties of antibodies and their complexes with antigens in solution. To study this relationship, a new technique, liquid-liquid partition chromatography (LLPC) in aqueous two-phase systems, was developed further with respect to sensitivity, selectivity and reproduc

This thesis concerns a highly efficient nanoparticle-based capillary electrochromatography separation technique and its coupling with mass spectrometric detection. From chromatographic theory, it is well known that the separation efficiency increases with decreasing particle size. However, as the particle size decreases, the pressure required to push a liquid through the column also increases. Thi
