  2. 1. Control or elimination : terms for public health interventions against tungiasis and schistosomiasis haematobium

    Author : Per Nordin; Ingela Krantz; Stig Wall; Andreas Ruppel; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tungiasis; urogenital schistosomiasis; control; elimination; public health; intervention; diagnosis; treatment; neglected tropical diseases; praziquantel; mass treatment; Public health; folkhälsa;

    Abstract : The thesis revolves around diagnosis and treatment of tungiasis (sand flea disease) and schistosomiasis haematobium. The causing parasites, Tunga penetrans and Schistosoma haematobium, both have the ability to penetrate intact skin. READ MORE

  4. 2. The cell wall ultrastructure of wood fibres : effects of the chemical pulp fibre line

    Author : Jesper Fahlén; Ulf W. Gedde; Drek G. Gray; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; atomic force microscopy; cellulose; cell wall; drying; fiber; Kemiteknik; Chemical engineering; Kemiteknik;

    Abstract : Knowledge of the ultrastructural arrangement within wood fibres is important for understanding the mechanical properties of the fibres themselves, as well as for understanding and controlling the ultrastructural changes that occur during pulp processing. The object of this work was to explore the use of atomic force microscopy (AFM) in studies of the cell wall ultrastructure and to see how this structure is affected in the kraft pulp fibre line.

  5. 3. Large Eddy Simulation of Turbulent Flows in Combustor Related Geometries

    Author : Jessica Gullbrand; Institutionen för energivetenskaper; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical engineering; Energiforskning; Energy research; Cartesian grid; high order wall treatment; SGS models; turbulence; subgrid scale models; LES; Large Eddy Simulation; akustik; vibrationer; vakuumteknik; hydraulik; vibration and acoustic engineering; Maskinteknik; vacuum technology; hydraulics;

    Abstract : Numerical simulations using Large Eddy Simulation (LES) are applied to turbulent swirling flow fields. The swirling motion is often introduced into combustors to act as flame holders or enhance the mixing between species. Different turbulence models capture the swirling motion more or less accurately.

  6. 4. Components for area-efficient stormwater treatment systems

    Author : Ivan Milovanovic; Annelie Hedström; Inga Herrmann; Jovan Despotovic; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stormwater; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

    Abstract : With progressing urbanisation, treatment of urban stormwater is a vital issue that should be addressed to ensure good water quality in receiving water bodies. Treatment may be performed near the source, with different filter systems using various filter materials, or by using an end-of-pipe method, e.g. a stormwater pond. READ MORE

  7. 5. High-Performance Composites from Modified Wood Fiber

    Author : Mats Westin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kraft lignin; fiberboard; lignocellulosic fiber; durability; wood fiber; mechanical properties; dimensional stability; decay resistance; acetylation; composite;

    Abstract : The objective of this work was to produce and evaluate high-performance wood fiber composites. High-performance was defined as: high dimensional stability and a high durability, including resistance to wood-decaying organisms (fungi, bacteria, and insects). READ MORE
