    Author : Åsa Laestadius; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Urinary tract infections will often, particularly in children, lead to renal scar formation or hypoplastic small kidneys post-infectiously. The most common causative agent is uropathogenic Escherichia coli (E. coli). READ MORE

  4. 2. Foundation of Density Functionals in the Presence of Magnetic Field

    Author : Andre Laestadius; Michael Benedicks; Trygve Helgaker; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Current density functional theory; Hohenberg-Kohn theorems; paramagnetic current density functionals; Kohn-Sham theory; Levy-Lieb functional; variational principle; N-representable; degeneracy; Mathematics; Matematik;

    Abstract : This thesis contains four articles related to mathematical aspects of Density Functional Theory.In Paper A, the theoretical justification of density methods formulated with current densities is addressed. It is shown that the set of ground-states is determined by the ensemble-representable particle and paramagnetic current density. READ MORE

  5. 3. Towards a sustainable automotive industry : experiences from the development of emission control systems

    Author : David Bauner; Staffan Laestadius; Lee Schipper; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; evolutionary economics; environmental innovation; trajectories; co-evolution; Industrial engineering and economy; Industriell teknik och ekonomi;

    Abstract : From the mid-1970s and on, the contribution to air pollution of carbon monoxide, hydrocarbons and nitrogen oxides from gasoline passenger cars in the developed world has been reduced through co-evolution of regulation and commercial introduction of catalytic emission control technology, now part of hundreds of millions of cars, trucks and buses worldwide. This dissertation is a disaggregated study of the global introduction of catalytic emission control technology as a measure to reduce local air pollution. READ MORE

  6. 4. Creating Advantage: On the complexity of industrial knowledge formation in the knowledge-based economy

    Author : Linda Gustavsson; Laestadius Staffan; Keith Smith; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; knowledge formation; competitive advantage; complexity; proximity; regional innovation systems policy; low- and medium-technology industries; Industrial organisation; administration and economics; Industriell organisation; administration och ekonomi;

    Abstract : Knowledge as a resource and knowledge formation as a process are seen as central to providing nations and regions as well as firms with a competitive advantage. This is captured by the view that the economic and industrial landscape is currently undergoing a transformation towards a knowledge-based economy. READ MORE

  7. 5. Survival of the Unfit : Path Dependence and the Estonian Oil Shale Industry

    Author : Rurik Holmberg; Staffan Laestadius; Mats Bladh; Mats Söderström; Nick von Tunzelmann; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Estonia; oil shale; path dependence; lock-in; institutions; knowledge; Sweden; innovation; Soviet Union; technology; systems; energy; shale oil; electricity; fossil fuel; environment; economy; Technology and social change; Teknik och social förändring;

    Abstract : Estonia is the only country in the world, which is totally dependent on oil shale in its energy system. Although this fossil fuel exists in enormous quantities around the world, it has so far not been utilized on a larger scale. The reasons for this have been both economic and, in recent times, ecological. READ MORE
