    Abstract : In the year 2000, the alcohol habits of 1460 Swedish university students living in residence halls were assessed. The students had a mean age of 23.8 years, and 64% were male. The results from this baseline assessment show that the mean AUDIT score (± sd) was 10. READ MORE

  4. 2. Nutrient use strategies of plants of various life-forms in a subarctic environment : Nutrient conservation as an adaption to infertile habitats

    Author : Rolf Lutz Eckstein; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Mean residence time; Nutrient productivity; Nutrient use efficiency; Plant strategies; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; ekologisk botanik; Ecological Botany;

    Abstract : Plant performance in relation to limiting nutrients was analysed using the concept of nutrient use efficiency (NUE). NUE can be decomposed into (1) the nutrient productivity (aNP) and (2) the mean residence time (MRT). READ MORE

  5. 3. Physical activity, participation and self-rated health among older community-dwelling Icelanders : a population-based study

    Author : Solveig Arnadottir; Lillemor Lundin-Olsson; Elin Dianna Gunnarsdottir; Gunnevi Sundelin; Alan M Jette; Umeå universitet; []

    Abstract : Background: The main objective of this study was to investigate older people’s physical activity, their participation in various life situations, and their perceptions of their own health. This included an exploration of potential influences of urban versus rural residency on these outcomes, an evaluation of the measurement properties of a balance confidence scale, and an examination of the proposed usefulness of the International Classification of Functioning, Disability and Health (ICF) as a conceptual framework to facilitate analysis and understanding of selected outcomes.

  7. 5. Parameters in wet grinding : the influence of process variables on autogenous and conventional grinding

    Author : Hongxin Zhai; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : The effects of autogenous and conventional grinding on the liberation of particles have been studied on the laboratory, pilot and industrial scales. It appears that autogenous grinding, down to flotation fineness, results in a higher degree of liberation and smoother particle surface for flotation, than is obtained with conventional grinding.
