    Author : Krister Nielsen; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; magnetic and optical properties; supraconductors; magnetic resonance; relaxation; Kondenserade materiens egenskaper:elektronstruktur; spectroscopy; rymdvetenskap; kosmisk kemi; Astronomi; Astronomy; spektroskopi; magnetisk resonans; supraledare; magnetiska och optiska ; egenskaper elektriska; space research; cosmic chemistry; stellar magnetic fields; branching fractions; spectral line structure; Fysicumarkivet A:2002:Nielsen; Condensed matter:electronic structure; line blending; electrical;

    Abstract : This thesis is a description of how knowledge of atomic physics can be used in a stellar spectrum analysis. Stellar investigations are spectroscopically performed based on wavelengths, intensities and spectral line structure. READ MORE

  4. 2. Knowledge intensive business services in non-core areas : Preconditions and strategies for value creation and competitiveness

    Author : Hjalti Nielsen; Institutionen för kulturgeografi och ekonomisk geografi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; KIBS; Tjänster; Icke-kärnområden; Perifera regioner; Agglomerationsfördelar; IKT-teknik; KIBS; Services; Non-core areas; Peripheral regions; Agglomeration advantages; ICT technologies;

    Abstract : Knowledge intensive business services (KIBS) play a key role in economic development. Due to the complex and collaborative nature of their value creation processes, it is conventionally argued that they depend strongly on physical proximity to large client-, and labour-markets, as well as on closeness to advanced knowledge infrastructures.

  5. 3. Words Matter in the Woods : Discourses on Deforestation in Global Climate Politics

    Author : Tobias Nielsen; Statsvetenskapliga institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Global climate politics; deforestation; REDD ; UNFCCC; argumentative discourse analysis;

    Abstract : Over the past decade, avoiding deforestation has become a central element of the UN Framework Convention on Climate Change (UNFCCC). The focal point of this has been the incentive-based mechanism of REDD+, which stands for Reducing Emissions from Deforestation and forest Degradation. READ MORE

  6. 4. Coal, commerce and communism : Empirical studies on energy history in the Czech Republic

    Author : Hana Nielsen; Ekonomisk-historiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; industrialization; coal; modern economic growth; central planning; iron and steel; energy efficiency;

    Abstract : This thesis employs an international comparative perspective to empirically analyse the Czech energy transition between 1830 and 2010. It addresses the utilization of energy in shaping modern economic growth through structural and technological change and the implications of those changes on specialization and foreign trade.

  7. 5. Process development for combined pentose and hexose fermentation

    Author : Fredrik Nielsen; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioethanol; Lignocellulose; Xylose fermentation; Co-fermentation; Process design; Agricultural residues; Saccharomyces cerevisiae;

    Abstract : Second-generation ethanol from lignocellulose is a sustainable alternative that can partially replace fossil fuels. To be competitive with first generation ethanol from sugar and starch crops and fossil fuels, the conversion efficiency and ethanol yields of second-generation ethanol conversion processes must be improved.
