  2. 1. Forest Dependence in Developing Countries : Analysis of household perceptions, energy, and food security in Tanzania

    Author : Matilda Ntiyakunze Stanslaus; Jesper Stage; Razack Lokina; Lars Hultkrantz; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Abstract : This thesis explores forest dependence in developing countries by examining households’ perceptions about their forest use and dependence, energy choices and the links between forests and food security in a case study of Tanzania. Paper (I) reviews selected economic literature related to the role of household heterogeneities on forest dependence and on energy choices. READ MORE

  4. 2. Aerodynamic design framework for low-pressure compression systems

    Abstract : The thesis investigates the dynamics of fluid particles in turbulent flows, which plays an important role in the chemical, pharmaceutical, food and petroleum industries. Phenomenological studies, new mathematical models for the breakup phenomena, and development of a simulation method for chemical reactors constitute the main parts of this thesis. READ MORE

  7. 5. Matchmaking in pain practice : challenges and possibilities

    Author : Sofia Bergbom; Steven J. Linton; Katja Boersma; William Shaw; Örebro universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; pain; psychological profiles; psychological treatment; early intervention; secondary prevention; treatment matching; Psychology; Psykologi;

    Abstract : All people experience pain and for some people, acute pain may over time develop into long-term disabling problems. Already at an early stage, it is possible to identify people at risk for long-term problems and psychologically oriented interventions have been shown to successfully prevent future disability.
