1. Spatial modeling in sediments
Sammanfattning : In a marine environment the sediments play an important role. They act as sinks, where the concentrations often are higher than in the water mass above, but also as sources for numerous pollutants. LÄS MER
2. Autoimmune hepatitis : life, death and in-between
Sammanfattning : Background Autoimmune hepatitis (AIH) is a chronic autoimmune liver disease that is overrepresented in women (75% of cases). Studies have described a 10-year survival after diagnosis near to that of the general population, but less is known about the long-term survival. LÄS MER
3. Provenance, transport, and the fate of organic matter and sediments drained through Himalayan Rivers in Nepal
Sammanfattning : Despite its small area (ca. 595,000 km2), the Himalayan region transfers disproportionally high amounts of sediments and organic matter (OM) through a network of rivers into the oceanic sink. LÄS MER
4. Study on the structure and properties of xylan extracted from eucalyptus, sugarcane bagasse and sugarcane straw
Sammanfattning : Lignocellulosic biomasses are an important source of chemical components such as cellulose, lignin and hemicelluloses, and can be used for a variety of purposes in both the pulp and paper and chemical conversion industries. Xylan, the main hemicellulose found in hardwood and grass plants, plays an important role during the pulping/pretreatment process reactions, including those used in 2nd generation bioethanol production.

5. Microbial Communities in Boreal Peatlands : Responses to Climate Change and Atmospheric Nitrogen and Sulfur Depositions
Sammanfattning : Myrmarker har en stor roll i regleringen av den globala kolbalansen och koncentrationerna av koldioxid och metan i atmosfären, vilket gör dem till speciellt viktiga ekosystem ur ett klimatförandringsperspektiv. Förändringar av myrmarker genom naturlig utveckling eller antropogen påverkan kan därför få långtgående störningar av myrars klimatreglerande funktion. LÄS MER
