  2. 1. The Lure of Origins : An Inquiry into Human-Environmental Relations, Focused on the ”Neolithization” of Sweden

    Author : Per Johansson; Humanekologi; []
    Keywords : HUMANIORA; HUMANITIES; Neolithization; Origins research; Organism concept; Artifact concept; Person concept; Ecological relations; Human-environment relations; Human ecology; Umwelt concept; Symbolism; Archaeology; Tim Ingold; Early Neolithic in Sweden; Cultural anthropology; ethnology; Arkeologi; Kulturantropologi; etnologi;

    Abstract : The purpose of this dissertation is to contribute to the discussion of the deeper meaning, in our contemporary context, of the ”neolithization” of Sweden. The basis for the investigation is twofold: * a critical examination of recent research reports dealing mostly with the Early Neolithic of (Middle) Sweden which shows, inter alia, that ”agriculture” was of marginal importance for a very long time from about 4000 BC onwards, while, at the same time, the idea of ”the transition to farming” dominates discourse.

  4. 2. Fragmentation and waste rock compaction in small-scale confined blasting

    Author : Daniel Johansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Abstract : Sub-level caving (SLC) is an important mass mining method, used at LKAB e.g. The caved rock or debris at the SLC interface reduces the fragmentation and the swelling of the blasted ring and it dissipates the explosive energy. These phenomena may immobilize the blasted ring, causing ore losses. READ MORE

  5. 3. Urban Design and Outdoor Thermal Comfort in Warm Climates. Studies in Fez and Colombo

    Author : Erik Johansson; Boende och bostadsutveckling; []

    Abstract : In many developing tropical countries, rapid urban growth leads to several problems, including increased thermal stress. This has negative consequences for people's health and well-being, and affects social and commercial outdoor activities negatively. READ MORE

  6. 4. Gene description, activity quantification and physiological responses of mitochondrial alternative NAD(P)H dehydrogenases

    Author : Fredrik Johansson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phytogeography; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .; morphology; taxonomy; Systematic botany; plant mitochondria; NAD P H dehydrogenases; cold treatment; complex I; light dependence; antimycin a; alamethicin;

    Abstract : In addition to proton-pumping complex I, the plant respiratory chain contains type II NAD(P)H dehydrogenases. These extra enzymes do not pump protons and consequently do not contribute to the electrochemical proton gradient. READ MORE

  7. 5. Metabolic analysis of shikimic acid producing Escherichia coli

    Author : Louise Johansson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Biokemi; metabolism; Chemical technology and engineering; transcriptome analysis; phosphorus-limitation; carbon-limitation; fed-batch; chemostat; batch; fermentation technology; Escherichia coli; shikimic acid; Biotechnology; Bioteknik; Metabolism; Biochemistry; principal component analysis; 2D-fluorescence spectrophotometry; metabolic flux analysis; carbon-rich;

    Abstract : Shikimic acid production using recombinant E.coli has been developed during the past 15 years due to the increased demand of this product, primarily as a starting material for the anti-influensa medicine Tamiflu?. A detailed metabolic analysis of a shikimic acid producing E. READ MORE
