  1. 1. Studies in Glacier Mass Balance : Measurement and its errors

    Författare :Andrew Mercer; Peter Jansson; Gunhild Rosqvist; Ian Brown; Jonathan Carrivick; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Glaciology; Mass Balance; Measurement Errors; Physical Geography; naturgeografi;

    Sammanfattning : The study of the surface mass balance of valley glaciers has a long history but one that is dogged by uncertainty and errors, and uncertainty about those errors. These problems are acknowledged by the glaciological community and have been examined and formalised in several publications. LÄS MER

  3. 2. Assessment of Raw Materials in Stainless Steelmaking-Their Energy Consumption and Greenhouse Gas Emission

    Författare :Wei Wenjing; Anders Tilliander; Peter Samuelsson; Pär Jönsson; Ye Guozhu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; static process model; mass and energy balance; molybdenum; nickel; phosphorus; stainless steel; life cycle assessment; GHG emission; energy consumption; statisk procesmodell; mass- och energibalans; molybden; nickel; fosfor; rostfritt stål; livscykelanalys; växthusgasutsläpp; energiförbrukning; Metallurgical process science; Metallurgisk processvetenskap;

    Sammanfattning : In stainless steelmaking, around 68% of the total greenhouse gas emissions come from the processing of raw materials. Thus, it is important for steelmakers to make efforts together with their raw material suppliers to implement low-carbon initiatives. To facilitate such initiatives, assessment of raw materials will provide guidance. LÄS MER

  4. 3. Simplifying complex models : Application of modeling tools in exposure assessment of organic pollutants

    Författare :Emma Undeman; Michael McLachlan; Kathrin Fenner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mass balance model; environmental modeling; exposure modeling; bioaccumulation; organic contaminants; emission estimate; plant model; steady state; poly parameter linear free energy relationship; PPLFER; ecosystem susceptibility; Environmental chemistry; Miljökemi; Persistent organic compounds; Persistenta organiska föreningar; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Thousands of chemicals are used in society, but the exposure to humans and other organisms has been measured only for a small number of compounds. Modeling tools constitute low-cost and effective alternatives to measurements for the assessment of exposure. LÄS MER

  5. 4. Nutritional status, body composition and physical activity among older people living in residential care facilities

    Författare :Maine Carlsson; Yngve Gustafson; Frode Slinde; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nutritional status; constipation; BW loss; UTI; body composition; exercise; muscle mass; functional balance; Nutrition; Näringslära; näringslära; Nutrition;

    Sammanfattning : The main purpose of this thesis was to study, whether drinkable yoghurt enriched with probiotic bacteria could have any effect on constipation and body weight (BW) among older people with dementia. Further, it concerns poor nutritional status among older people with physical and cognitive impairments and its relationship with factors commonly occur in older people living in residential care facilities.

    Sammanfattning : The overall aim of the research presented here was to expand the knowledge on metabolic course and nutritional outcome in patients with severe traumatic brain injury and to analyze the use and accuracy of different methods of assessment. Study I, a systematic review of 30 articles demonstrated consistent data on increased metabolic rate, of catabolism and of upper gastrointestinal intolerance in the majority of the patients during early post injury period.
