  1. 1. Informell Statistisk Inferens i modelleringssituationer : En studie om utveckling av ett ramverk för att analysera hur elever uttrycker inferenser

    Författare :Per Blomberg; Per Nilsson; Jonas Bergman Ärlebäck; Andreas Ryve; Linnéuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Conceptual framework; Data; Informal statistical inference; Modelling; Statistical inquiry; Statistics education; Pedometer; Use-Inspired Basic research; Begreppsramverk; Behovsmotiverad grundforskning; Modellering; Mätdata; Informell Statistisk Inferens; Statistisk undersökning; Statistikundervisning; Stegräknare; Mathematical Education; Matematikdidaktik;

    Sammanfattning : Syftet med denna studie är att bidra med ökad kunskap om lärande och undervisning i informell statistisk inferens. I studien användes en kvalitativ forskningsstrategi inriktad mot prövning och generering av teorier med inspiration av grounded theory. LÄS MER

  3. 2. Biomimetic Transition Metal Catalysts : Insights from Theoretical Modeling

    Författare :Adam Johannes Johansson; Per E. M. Siegbahn; Margareta R. A. Blomberg; Per-Ola Norrby; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Catalysis; biomimetic; copper; non-heme iron; heme iron; O2 cleavage; H-atom transfer; radical chemistry; redox chemistry; thermo chemistry; entropy calculations; quantum chemistry; spin states; density functional theory DFT ; self-interaction error SIE .; Chemical physics; Kemisk fysik; kemisk fysik; Chemical Physics;

    Sammanfattning : The scientific interest in the chemistry of synthetic transition metal complexes is motivated by at least two arguments:1.These can be regarded as models of biological transition metal complexes, e.g. metalloenzymes, whose functions can be difficult to reveal in detail due to their complexity.

  4. 3. Experimental validation of dynamic component models

    Författare :Per E. Blomberg; KTH; []
    Nyckelord :;

    Sammanfattning : Proper coil function is an important issue regardingair-handling devices. Thus, proper modeling is important. Thepresent work deals with simulation of heating coil subsystems,especially validation on component level. LÄS MER

  5. 4. Att besvärja döden : Död- och återfödelsetematiken i Lars Noréns författarskap 1963-1999

    Författare :Yvonne Blomberg; Tom Hedlund; Per Bäckström; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Lars Norén; modern Swedish literature; thematic method; myth interpretation; chronos; kairos; death and resurrection; Literature; Litteraturvetenskap; litteraturvetenskap; Literature;

    Sammanfattning : Lars Norén’s poetical world is filled with the living and the dead, history and memory. This study is the first one of its kind that treats myths and religious ideas in Norén’s works. Its aim is to examine the centre of his oeuvre, namely a striving in the texts to heal disintegration and to beseech death in order to maintain a life process. LÄS MER

  7. 5. Redox Reactions of NO and O2 in Iron Enzymes : A Density Functional Theory Study

    Författare :Mattias Blomberg; Per Siegbahn; Adrian Mulholland; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; enzyme catalysis; redox reactions; cytochrome oxidase; nitric oxide reductase; hyponitrous acid anhydride; peroxynitrite; myoglobin; prostaglandin synthase; PGHS; NO; N2O; O2; CO; Chemical physics; Kemisk fysik;

    Sammanfattning : In the present thesis the density functional B3LYP has been used to study reactions of NO and O2 in redox active enzymes.Reduction of nitric oxide (NO) to nitrous oxide (N2O) is an important part in the bacterial energy conservation (denitrification). LÄS MER
