Popular Abstract in Swedish Populärvetenskaplig sammanfattning Den här avhandlingen handlar om förbättringar aven process för att producera sk. kirala aminer -en typ av molekyler som ingår bl.a. i många läkemedel. Kirala molekyler är de som finns i två former, sk. enantiomerer, som är varandras spegelbild. Trots sina kemiska och fYsikaliska likheter kan de ha mycket olika biologisk effekt. Ett välThe industrial use of biocatalysts is increasingly important in the production of e.g. pharmaceuticals, chemicals, fuels and foodstuffs. A successful biocatalytic process is dependent on many factors, such as the biocatalyst properties, the nature of the reaction, reactor type and downstream processing. This work is focused on two important issues: Immobilization of the biocatalyst and in situ pro

Popular Abstract in SwedishEn av de viktigaste forskningsfrågorna inom matematikutbildning handlar om förståelse. Det huvudsakliga syftet med den här avhandlingen har varit att nå insikt i olika förståelseformer i skolmatematik och former av lärandeidentiteter i två lärandemiljöer. Avhandlingens specifika fokus var flexibla sätt att urskilja delar och avgränsa helheter och undersöka hur lärande inA central question in mathematics education research concerns understanding. The main objective of the present thesis has been to obtain insights into flexible modes of knowing in school mathematics in two school class contexts, and how these relate to modes of being a learner in these contexts, with specific focus on learners’ flexible ways of discerning parts and delimiting wholes, and how they

The Independent Film Group – an experimental film co-op in 1950s Stockholm - is presented, as well as the formation of a discourse on experimental film.

Using “fortress model” of urban planning as part of normative and ideological endeavors to Islamize the society, Iranian Islamic government has systematic implemented gender-segregation policies, among others, in public urban spaces. The most recent efforts in a long line of policies and practices include “women-only parks” claimed to be designed and administrated entirely by women to accommodate

The recognition of new venture opportunities has been acknowledged as one of the most important abilities of successful entrepreneurs. Explaining the recognition of new venture opportunities has thus become an important element of the scholarly study of entrepreneurship. Building on this stream of research, we present a study of the influence of prior industry and functional work experience on ent

Soot particles can be formed in hydrocarbon flames as a result of an inefficient combustion process. The particles are near-spherical, and normally a few tens of nanometers in diameter. At later stages in the soot growth process, they form chain-like sparse aggregates. When applying optical diagnostic methods such as combined scattering and extinction measurements in sooting flames, this aggregati
