2. 1. Age differences in first language attrition : A maturational constraints perspective

   Author : Emanuel Bylund Spångberg; Kenneth Hyltenstam; Niclas Abrahamsson; Silvina Montrul; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; first language attrition; age differences; maturational constraints; critical period; language acquisition; bilingualism; international adoptees; conceptual proficiency; language aptitude; Bilingualism; Tvåspråkighet; tvåspråkighetsforskning; Bilingualism;

   Abstract : This thesis investigates age-related differences in first language (L1) attrition in a second language (L2) setting. The thesis is based on four individual studies. READ MORE

4. 2. Recycling plant nutrients from waste and by-products : a life cycle perspective

   Author : Johanna Spångberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Chemical fertilisers contribute to greenhouse gas emissions, fossil fuel use, use of non-renewable phosphate rock and a flow of reactive nitrogen to the biosphere, exceeding the planetary boundaries. Recycling of plant nutrients from waste and by-products from society would reduce the use of chemical fertilisers. READ MORE

5. 3. Cation Solvation in Water and Acetonitrile from Theoretical Calculations

   Author : Daniel Spångberg; Kersti Hermansson; Philippe Bopp; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; molecular dynamics; ab initio; lithium; sodium; magnesium; aluminum; metal ion; water; acetonitrile; solution; solvation; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

   Abstract : Metal ions solvated in aqueous, non-aqueous, and mixtures of solvents occur in many chemical contexts, for example in electrochemical applications and solvent separation. Solvated ions appear in high concentration in the living organisms, where their presence or absence can fundamentally alter the functions of life. READ MORE

6. 4. Cellular proteins binding to the HCV 5' and 3' UTRs

   Author : Karin Spångberg; Ingemar Ernberg; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Hepatitis C virus; RNA-binding proteins; mRNA stability; translation; Biokemi; Biochemistry; Biokemi; Medical Virology; medicinsk virologi;

   Abstract : Hepatitis C virus (HCV) is a worldwide health problem with more than 170 million people infected by the virus. About 80% become chronic carriers, which may result in hepatocellular carcinoma. The lack of an in vitro cell culture system that allows propagation of the virus has hampered the development of a vaccine or anti-viral drugs against HCV. READ MORE

7. 5. Insights to beachcast management on Gotland, Sweden : An Industrial Ecology perspective on waste-resource ambiguity

   Author : Hanna Nathaniel; Fredrik Gröndahl; Daniel Franzén; Sofia Lingegård; Johanna Spångberg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Beachcast; natural resource management; policy; circular bio-economy; agroecosystems; governance; sustainable development; industrial ecology; Släke; naturresursteknik; policy; cirkulär bioekonomi; agroekologiska system; naturresursförvaltning; hållbar utveckling; industriell ekologi i; Industriell ekologi; Industrial Ecology;

   Abstract : Beachcast or beach wrack, washed-up algae and seaweed, used to be a highly sought-after agricultural resource (fertiliser and soil conditioner) in coastal communities around the world before being replaced by chemical fertilisers, but considering the talks of a circular bio-economy – can we reintroduce it? Since the abandonment of beachcast in agriculture, the amount of beachcast has significantly increased as an effect of eutrophication caused by the use of chemical fertiliser, and the material is commonly considered waste. Meanwhile, soils have degraded and need the multiple positive effects on agroecosystems that beachcast could provide. READ MORE
