    Sammanfattning : Paper [I] In this paper, we study a Green Public Procurement (GPP) policy decided by the Swedish government in 2006, stating objectives related to organic farming. The policy aims to increase the public sector's organic food purchases, in order to incentivise Swedish farmers to convert to organic practices, thereby contributing to national environmental quality objectives.

    Sammanfattning : Supplemental special education support in reading and mathematics is essential for some children who struggle to learn basic reading or mathematics skills in their first years of schooling. Previous research shows that supplemental phonics and early numeracy and arithmetic instruction help students at risk for reading or mathematics difficulties. LÄS MER

  5. 4. Understanding Opioid Therapy in Chronic Pain : Assessment, Lived Experience and Conceptions

    Författare :Hanna Ljungvall; Pernilla Åsenlöf; Nitya Jayaram-Lindström; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : The overarching aim of this thesis was to improve the understandings of opioid therapy for chronic non-cancer pain (CNCP) by examining the feasibility of different assessment methods of substance use, and opioid use disorder (OUD), and exploring the sense-making of opioid therapy in CNCP.  Methods: In study I, the reliability of the Addiction Severity Index Self-Report form (ASI-SR) was assessed by the agreement (intraclass correlation (ICC)) between the composite scores (CS) of the ASI interview and the ASI-SR, internal consistency of the CS subscales measured with Cronbach’s α, and sensitivity and specificity of the alcohol and drug CS’s, using Receiver Operating Characteristics analyses.

  7. 5. Lattice Boltzmann simulations of two-phased flow in fibre network systems

    Författare :Hanna Wiklund; Tetsu Uesaka; Stefan Lindström; Jonas Örtegren; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Two-phase flow in microfluidic systems is of great interest for many scientificand engineering problems. Especially in the pulp and paper area, the problems spanfrom fibre-fibre interactions in the consolidation process of papermaking to edgewickingin paper board during the aseptic treatment of liquid packaging.
