  2. 1. Tribological and Mechanical Behaviour of Lamellar and Compacted Graphite Irons in Engine Applications

    Author : Rohollah Ghasemi; Anders Professor; Lennart Assistance professor; Bengt-Göran Rosén; Anders Jarfors; Lennart Elmquist; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sliding wear; abrasive wear; graphite lubricating performance; matrix deformation; lamellar graphite iron; high-Si compacted graphite iron;

    Abstract : There has been much discussion about the beneficial uses of lamellar graphite iron in piston rings–cylinder liner systems, where a good combinations of both thermal and tribological properties are essential. The excellent tribological performance of lamellar iron under such sliding conditions is principally associated with lubrication behaviour of the graphite particles which are distributed as lamellas throughout the matrix.

  4. 2. Quantitative morphological studies of the parathyroid gland

    Author : Hans-Olov Larsson; Ronny Lorentzon; Lennart Boquist Lennart Boquist; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parathyroids; stereology; electron microscopy;

    Abstract : This work is based upon a series of quantitative morphological studies of the parathyroid glands of Mongolian gerbils and rats. Standard stereological methods were used on light and electron microscopical levels. READ MORE

  5. 3. Methodology for evaluation of hazards from solid waste and landfill-generated leachate

    Author : Britt-Marie Svensson; Lennart Mathiasson; Lennart Mårtensson; Ann-Sofi Rehnstam-Holm; Kenneth M. Persson; Högskolan Kristianstad; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Analytical protocol; organic pollutants; toxicity test; landfill leachate; leachate treatment; leaching test; waste acceptance criteria; Chemistry; Kemi; NATURAL SCIENCES; NATURVETENSKAP; leaching test; waste acceptance criteria.;

    Abstract : A methodology based on an analytical protocol for evaluation of hazards from landfill leachate and solid waste is described. A dynamic analytical protocol, the LAQUA protocol, including measurements of inorganic and water-quality parameters, polar and non-polar organic marker compounds, and toxicity, was constructed.

    Keywords : ;

    Abstract : Avfall har alltid uppkommit i alla samhällen i alla tider. Det vanligaste sättet att hand om det har varit att samla avfallet i soptippar (deponier) på mark som ansetts obrukbar, t.ex. i sankmarker utanför bebyggelsen. READ MORE

  7. 5. Early life factors and the long-term development of asthma

    Author : Hartmut Vogt; Lennart Nilsson; Lennart Bråbäck; Karin Fälth-Magnusson; Catarina Almqvist Malmros; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; asthma; birth cohort; national register;

    Abstract : Asthma, a huge burden on millions of individuals worldwide, is one of the most important public health issues in many countries. As genetic and   environmental factors interact, asthma may be programmed very early in life, perhaps even in utero. READ MORE
