   Sammanfattning : Second-order nonlinear optical processes generate radiation across a broad spectrum, including UV and the far-infrared. In this thesis, new light sources in the near(NIR) and mid infrared (MIR) using three-wave mixing geometries in periodically poled potassium titanyl phosphate (PPKTP) is studied. LÄS MER

3. 22. I viljan att göra det normala : En kritisk studie av genusperspektivet i missbrukarvården

   Författare :Tina Mattsson; Socialhögskolan; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social sciences; Femininity; Masculinity; Drug abuse treatment; Ethnicity; Class; Sexuality; Sex; Gender; Social work; Social changes; theory of social work; Samhällsvetenskaper; Sociala förändringar; teorier om socialt arbete;

   Sammanfattning : The aim of this dissertation is to use intersectional analysis to investigate how gender is made in drug abuse treatment and to examine how the formation of gender interplays with the formation of sexuality, class and ethnicity. Central questions are: What gender(s) are to be shaped in druge abuse treatment? What happens to a gender perspective with emancipatory ambitions when it is incorporated into a normalizing practice such as social work? Quantitative methods are used to answer these questions.

4. 23. Wheelchair Passengers and Local Public Transport Vehicles: Perceptions of Safety and Comfort

   Författare :Anders Wretstrand; Trafik och väg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road transport technology; Public transport; Bus; STS; Perception; Comfort; Wheelchair users; Safety; Vägtransportteknik; Care and help to handicapped; Handikappade; vård och rehabilitering;

   Sammanfattning : Eliciting wheelchair-seated passengers’ perspective of safety and comfort is both useful and mandatory, particularly for researchers, clinicians, transit authorities, and for operators during purchase and use of vehicle technologies in existing and planned future transport systems. Therefore, the overarching objective of this thesis was to delineate the question of safety and comfort as perceived by wheelchair-seated passengers using public transport road vehicles. LÄS MER
