  2. 16. Beware of Non-Supportive Leaders : Moderating Effects of Supportive Leadership on the Risks and Effects of Workplace Bullying

    Author : Stefan Blomberg; Michael Rosander; Bengt Ståhlbom; Duncan Lewis; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Workplace bullying; Supportive leadership; Health; Role ambiguity; Hostile work climate; Moderation; Longitudinal; Arbetsplatsmobbning; Stödjande ledarskap; Hälsa; Otydliga roller; Fientligt arbetsklimat; Moderation; Longitudinell;

    Abstract : The aim was to investigate how supportive leadership affects workplace bullying—both in terms of risk factors that may lead to bullying but also in terms of the effects of bullying. The thesis includes three survey studies based on different Swedish cohorts and using different research design in terms of the number of data collection waves and timeframes. READ MORE

  4. 17. Combined speckle interferometry and speckle correlation for non-destructive testing

    Author : Angelica Andersson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Abstract : When a sample is studied during loading in a tensile test machine, the sample is often exposed to rigid body motions during loading at the same time as it deforms due to tension. Therefore, the small deformation field is hard, or impossible, to measure when it is overlaid by a large motion. READ MORE

  5. 18. Non-destructive detection of glue deficiency in laminated wood using thermography

    Author : Henrik Berglind; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Abstract : The purpose of the work described in this doctorate thesis has been to study the potential of the non-contact and non-destructive test (NDT) method, thermography, to detect glue deficiency beneath a thin laminated layer of wood. The technological applications can for example be found in the parquet flooring industry. READ MORE

  6. 19. Medical CT-scanners for non-destructive wood density and moisture content measurements

    Author : Owe Lindgren; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Abstract : Most methods to measure wood density and moisture content are destructive. One non-destructive technique is X-ray computed tomography (CT). The actual physical variable measured is the X-ray linear attenuation coefficient which is highly density dependent. READ MORE

  7. 20. Gamma radiation techniques for non-destructive post-irradiation examination of nuclear fuel : Predicting performance and optimizing instrument design

    Author : Lorenzo Senis; Peter Andersson; Erik Andersson Sundén; Ane Håkansson; Fabiola Cappia; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Collimated gamma spectroscopy; Gamma emission tomography; Gamma transmission micro-densitometry; Pareto optimization; Post-irradiation examination; Applied Nuclear Physics; Tillämpad kärnfysik;

    Abstract : Collimated gamma-based techniques are widely used to study nuclear fuel, especially for non-destructive post-irradiation examination (PIE). Examples of such techniques include gamma emission tomography (GET) and gamma transmission densitometry (GTD). READ MORE
