  1. 1. Regulation of gene and protein expression : two model systems

    Författare :Lars H Lund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :HIV-1; EIAV; Tat; TAR; Cyclin T1; CDK9; P-TEFb; RNA polymerase II; gene regulation; transcriptional elongation; CEA; signal sequence.;

    Sammanfattning : Genetic information is expressed by DNA transcription and mRNA translation. With few exceptions, every cell of an organism, or the human body, contains the same genetic information. Yet the structure and function of different tissues are highly variable. LÄS MER

  3. 2. "Är det så här vi är" : Om utbildning som normalitet och om produktionen av studenter

    Författare :Lars-Olof Hilding; Ann-Mari Sellerberg; Lars-Erik Berg; Högskolan i Halmstad; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; utbildningssociologi; social snedrekrytering; högre utbildning; Sociology; Sociologi; sociology of education; social mobility; diversity in higher education;

    Sammanfattning : Avhandlingen, baserad på intervjuer med 58 studenter vid tre olika program vid Högskolan i Halmstad, behandlar de skäl olika studentgrupper beskriver för att börja studera, deras upplevelser av mötet med högskolemiljön, och vilken betydelse de en lokal högskola kan ha. Trots olika åtgärder var den sociala snedrekryteringen till högre utbildning i stort sett oförändrad mellan 1960 och 1990. LÄS MER

  4. 3. Fuel Cells and Biogas

    Författare :Lars Hedström; Per Alvfors; Peter Lund; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air bleed; biogas; carbon dioxide; carbon monoxide; current distribution; dilution; efficiency; energy conversion; energy systems; experimental; fuel cell; fuel cell systems; PEFC; poisoning; reformate; SOFC; Chemical energy engineering; Kemisk energiteknik;

    Sammanfattning : This thesis concerns biogas-operated fuel cells. Fuel cell technology may contribute to more efficient energy use, reduce emissions and also perhaps revolutionize current energy systems. The technology is, however, still immature and has not yet been implemented as dominant in any application or niche market. LÄS MER

  5. 4. Structural and Morphological Studies of Mesoporous Crystals

    Författare :Kristina Lund; Osamu Terasaki; Sven Lidin; Lars Eriksson; Mika Lindén; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry; Kemi; Structural Chemistry; strukturkemi;

    Sammanfattning : Mesoporous silica and carbon have been synthesised and characterised by X-ray diffraction (XRD), transmission and scanning electron microscopy (TEM and SEM) and nitrogen adsorption. Surface structure, size and shape (morphology) of particles have been of special interest in this work. LÄS MER

  7. 5. New methods for movement technique development in cross-country skiing using mathematical models and simulation

    Författare :Marie Lund Ohlsson; Mårten Gulliksson; Lars-Erik Persson; Fredrik Ståhl; Peter Carlsson; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied mathematics; Tillämpad matematik;

    Sammanfattning : This Licentiate Thesis is devoted to the presentation and discussion of some new contributions in applied mathematics directed towards scientific computing in sports engineering. It considers inverse problems of biomechanical simulations with rigid body musculoskeletal systems especially in cross-country skiing. LÄS MER
