  1. 6. Influence of Substrate Topography on Ink Distribution in Flexography

    Författare :Gustavo Gil Barros; Per-Åke Johansson; Gunnar Engström; Magnus Lestelius; Patrice J. Mangin; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paperboard; topography; optical measurement; OptiTopo; flexography; flexo; print quality; printability; uncovered area; UCA; image analysis; frequency analysis; surface properties; paper properties; test equipment; measuring instrument; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : The printability of paper in flexography is largely dependent on the topographical characteristics of the substrate. Topography imaging instruments make it possible to obtain three-dimensional scans of paper surfaces that can be further used to calculate valuable quality parameters. LÄS MER

  2. 7. Motivational aspects of test-taking : measuring test-taking motivation in Swedish national test contexts

    Författare :Eva Knekta; Hanna Eklöf; Anna Sundström; Rolf Vegar Olsen; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Test-taking motivation; Swedish national tests; validity; expectancy-value theory; task value; expectancies; young adolescents; self-report instrument; interview; structural equation modelling; test stakes; didactics of educational measurement; beteendevetenskapliga mätningar;

    Sammanfattning : The overall aim of the work underlying this thesis was to improve the understanding of students’ test-taking motivation in connection to achievement tests for young adolescents. The thesis includes four studies and a summary. All four studies explore test-taking motivation and are all connected to validity in one way of another. LÄS MER

  3. 8. Occupational stress among Thai emergency department nurses : Development and validation of an instrument for measuring stressors in emergency departments

    Författare :Nuttapol Yuwanich; Martin Lene; Sharareh Akhavan; Walaiporn Nantsupawat; Töres Theorell; Mälardalens högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Care Sciences; vårdvetenskap;

    Sammanfattning : Working at an emergency department has some characteristics, which may generate stress. In this thesis, the stressors for emergency nurses were evaluated and an instrument was developed for measuring their impact. LÄS MER

  4. 9. Determining the quality of natural gas and biomethane : Development of a correlative method and instrument prototype for measuring gas quality

    Författare :Taras Koturbash; Vladimir G. Kutcherov; Andrew R. Martin; Khaled Loubar; KTH; []
    Nyckelord :Natural gas; biomethane; calorific value; Wobbe Index; ultrasonic measurement; sound attenuation; Energy Technology; Energiteknik;

    Sammanfattning : The composition of natural gas highly depends on its origin: natural gas from various deposits, substitute natural gas that can be produced from fossil fuels or renewable sources. The intermixing of gases from various supply sources during pipeline transportation also leads to more complicated and unpredictable gas composition variations at the consumption site. LÄS MER

  5. 10. Measuring harm from drinking in Sweden : Self-reports from drinkers in the general population

    Författare :Klara Hradilova Selin; Robin Room; Lorraine Midanik; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Key words: AUDIT measure; validity; reliability; harm from drinking; social problems; summary measures; predictors of alcohol-related harm; general population surveys.; Sociology; Sociologi;

    Sammanfattning : There are several traditions of conceptualizing and measuring harm from drinking. Two main approaches are considered in the introduction – the psychiatric epidemiology and the social survey research traditions. LÄS MER
