  2. 1. Material Constraints on Technology Evolution: The Case of Scarce Metals and Emerging Energy Technologies

    Author : Björn A. Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; energy; metal scarcity; solar cell; sustainable development; technology policy; lock-in; industrial ecology; technical change; battery; electric vehicle;

    Abstract : A radical transformation of the energy system in the 21st century will require a large-scale diffusion of a range of new energy technologies. Thin-film solar photovoltaics (PV) and battery-electric vehicles have been suggested as possible major components of a more sustainable energy system. READ MORE

  5. 3. Contributions to Kernel Equating

    Author : Björn Andersson; Fan Yang-Wallentin; Marie Wiberg; Alina A. von Davier; Jorge González; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; observed-score test equating; item response theory; R; equipercentile equating; asymptotic standard errors; non-equivalent groups with anchor test design; Statistics; Statistik;

    Abstract : The statistical practice of equating is needed when scores on different versions of the same standardized test are to be compared. This thesis constitutes four contributions to the observed-score equating framework kernel equating. READ MORE

  6. 4. Reverse genetic studies of Enterovirus replication

    Author : Anna Sävneby; A. Michael Lindberg; Björn Andersson; Peter Gierow; Jonas Waldenström; Martin Ryan; Linnéuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Enterovirus; picornavirus; coxsackievirus; echovirus; rhinovirus; reverse genetics; replication; translation; transfection; cassette vector.; Virology; Virologi;

    Abstract : Enteroviruses belong to the Picornaviridae family and are small icosahedral viruses with RNA genomes of positive polarity, containing a single open reading frame. They mostly cause mild or asymptomatic infections, but also a wide array of diseases including: poliomyelitis, encephalitis, gastroenteritis, aseptic meningitis, myocarditis, hand-foot-and-mouth disease, hepatitis and respiratory diseases, ranging from severe infections to the common cold.

  7. 5. Mitochondrial and Eukaryotic Origins : A Phylogenetic Perspective

    Author : Björn Brindefalk; Siv Andersson; James McInerney; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular evolution; Phylogenetics; Mitochondrial origin and Evolution; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Mitochondria are eukaryotic cellular organelles responsible for power-generation, believed to have come into existence by an endo-symbiontic event where a bacterial cell was incorporated by an un-specified "proto-eukaryote". Phylogenetic analysis have shown that the mitochondrial ancestor was most related to present-day alpha-proteobacteria, although the exact nature of the mitochondrial progenitor remains disputed.
