1. 16. Development of Methods for Phase System Characterization in Liquid Chromatography

   Författare :Jörgen Samuelsson; Torgny Fornstedt; Karin Caldwell; Attila Felinger; Uppsala universitet; []
   Nyckelord :Analytical chemistry; Liquid chromatography; Adsorption isotherms; Adsorption energy distribution; Tracer pulse method; Elution by characteristic points; Peak deformation; Validation; Hybrid column material; Alkaline separation; Injection-profiles; Analytisk kemi;

   Sammanfattning : The aim of this thesis is first and foremost to improve the fundamental knowledge of nonlinear and preparative separation theory by focusing on some of the remaining “white spots” on the theoretical chromatographic map. Secondly, the acquired knowledge is used to develop, validate and execute new methods for phase characterization in liquid chromatography. LÄS MER

3. 17. Compartment Fire Temperature Calculations and Measurements

   Författare :Alexandra Byström; Ulf Wickström; Sven Thelandersson; Luleå tekniska universitet; []

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gerontologi; Gerontology; Validation; Social support; Social network; Nursing; Elderly; Minnesota Living with Heart Failure Questionnaire; Health related quality of life; Chronic heart failure;

   Sammanfattning : The aim of this thesis was to empirically and methodologically investigate health related quality of life (HRQoL) among persons 65 years or older with chronic heart failure. The design was cross-sectional and the sample was recruited from a southeast region of Sweden. LÄS MER

5. 19. Recidivism and Static-99R risk assessments in a Swedish cohort of mentally disordered sexual offenders

   Författare :Christian Baudin; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sex offenders; Recidivism; Static-99R; Validation; Rasch analysis;

   Sammanfattning : Mentally disordered sexual offenders (MDSOs) constitute a heterogeneous offender subgroup presenting a wide range of clinical comorbidity. The recidivism rates for such a disparate subgroup vary substantially, which complicates estimations of recidivism risk. LÄS MER

7. 20. As valid as it can be? : The assessment of prior learning in higher education

   Författare :Tova Stenlund; Peter Nystöm; Widar Henriksson; Patricia Murphy; Umeå universitet; []
   Nyckelord :Access to Higher Education; Recognition; Accreditation; Informal learning; Validity; Reliability; Validation; didactics of educational measurement; beteendevetenskapliga mätningar;

   Sammanfattning : Assessment of prior learning (APL) represents the task to identify and acknowledge an individual’s knowledge and skills regardless of how it has been obtained. In higher education this type of assessment is primarily used for the purpose of awarding access, credits or advanced standing. LÄS MER
