  1. 1. Particles from biomass combustion -Characteristics and influence of additives

    Author : Linda S Bäfver; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combustion; particle emission; wood; biomass; cereals; wood pellets;

    Abstract : AbstractHigh particle concentration in the air is a health risk, and particles from domestic biomass combustion are a significant particle source. In larger boilers, particles are an important element in the build-up of deposits on heat transfer surfaces, causing increased operation and maintenance costs. READ MORE

  2. 2. Biology, ecology and anthropogenic threats of Indo-Pacific bottlenose dolphins in east Africa

    Author : Omar A. Amir; Per Berggren; Graham Pierce; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Growth; reproduction; feeding ecology; bycatch; organohalogen compounds; dolphins; Tursiops aduncus; Zanzibar; East Africa; Marine ecology; Marin ekologi; zoologisk ekologi; Animal Ecology;

    Abstract : This thesis examines the biology, ecology and anthropogenic threats of Indo-Pacific bottlenose dolphins (Tursiops aduncus) off Zanzibar, Tanzania, based on research conducted and samples collected between 2000 and 2008. Distribution and occurrence are described based on incidental catches (bycatch) in gillnet fisheries. READ MORE

  3. 3. Building renovation processes towards low greenhouse gas emissions and energy use

    Author : Stefan Olsson; Tove Malmqvist; Göran Finnveden; Dennis Johansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renovation processes; buildings; energy efficiency; greenhouse gas emissions; target levels;

    Abstract : Buildings from the record year era are now 40 – 55 years old and in many cases in need of extensive renovation measures. This need for renovation could be seen as an opportunity to achieve overarching sustainability target levels and to perform renovation with a holistic approach. READ MORE

  4. 4. Epidemiological and molecular biological studies of multi-resistant methicillin-susceptible Staphylococcus aureus

    Author : Maria Lindqvist; Anita Hällgren; Barbro Isaksson; Lennart E. Nilsson; Christina Åhrén; Linköpings universitet; []
    Keywords : ;

    Abstract : Antibiotic resistance is increasingly recognised as a major problem and threat. During the last decades Gram-positive bacteria in general, and methicillin-resistant Staphylococcus aureus (MRSA) in particular, have been in focus both concerning matters of antibiotic resistance and as pathogens causing health care-associated (nosocomial) infections.

  5. 5. Mechanical Properties of Transition Metal Alloys from First-Principles Theory

    Author : Xiaoqing Li; Levente Vitos; Manuel Richter; KTH; []
    Keywords : ;

    Abstract : The aim of the thesis is to investigate the alloying effect on the mechanical properties of random alloys using the all-electron exact muffin-tin orbitals methodin combination with the coherent-potential approximation. The second-order elastic constants describe the mechanical properties of materials in the small deformation region, where the stress-strain relations arelinear. READ MORE
