21. Strategies for cellulose fiber modification
Sammanfattning : This thesis describes strategies for and examples ofcellulose fiber modification.The ability of an engineered biocatalyst, acellulose-binding module fused to theCandida antarcticalipase B, to catalyze ring-openingpolymerization of e-caprolactone in close proximity tocellulose fiber surfaces was explored.

23. The importance of biodiversity for ecosystem processes in sediments : experimental examples from the Baltic Sea
Sammanfattning : Aquatic sediments are, by surface, the largest habitat on Earth. A wide diversity of organisms inhabit these sediments and by their actions they have a large influence on and also mediate many ecosystem processes. LÄS MER
24. Biogeochemical processes in frozen soils : unfrozen water in frozen soils and factors regulating carbon mineralization at low temperatures
Sammanfattning : High latitude ecosystems are important for global carbon (C) balances and are among the most sensitive ecosystems to climate change. Microbial CO2 production in soil is known to proceed at temperatures < 0ºC in these regions and winter CO2 emissions can significantly affect annual C balances. LÄS MER
25. Vaikijaur, a palaeoproteroic Cu-Au porphyry style mineralization in the Jokkmokk granitoid at the archaean-proterozoic boundary in northern Sweden
Sammanfattning : The Jokkmokk granitoid is exposed in a plutonic massif northwest of Jokkmokk in northern Norrbotten. It is light grey to white, fine-grained, with megacrysts of feldspar and glomeroporphyritic hornblende and biotite. Small enclaves of mafic rocks and synplutonic mafic dykes are products of mingling with a coeval and possibly cogenetic mafic magma. LÄS MER
