1. 11. Knee Injury and Knee Osteoarthritis -Development, evaluation and clinical application of patient-relevant questionnaires

   Författare :Ewa Roos; Lund Ortopedi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rheumatology locomotion; muscle system; Skeleton; Knee injury osteoarthritis outcome pain function; Skelett; muskelsystem; reumatologi;

   Sammanfattning : The overall purpose was to evaluate patient-relevant outcomes in patients with knee injury and post-traumatic osteoarthritis of the knee. A self-administered questionnaire, The Knee injury and Osteoarthritis Outcome Score (KOOS) was developed by literature search, consulting an expert panel (including patients referred to physical therapy because of knee-related problems, orthopedic surgeons, and physical therapists both from Sweden and the USA), and a pilot study.

3. 12. The meaning(s) of inclusion in mathematics in student talk : Inclusion as a topic when students talk about learning and teaching in mathematics

   Författare :Helena Roos; Despina Potari; Hanna Palmér; Nùria Planas; Linnéuniversitetet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; inclusion in mathematics; discourse analysis; students meaning s ; Matematikens didaktik; Mathematics education; Mathematical Education;

   Sammanfattning : This thesis contributes to research and practice within the field of special education in mathematics with more knowledge about, and an understanding of, students´ meaning(s) of inclusion in mathematics education. Three research questions guide the study: What meaning(s) is/are ascribed, and how is inclusion used, in mathematics education research? What meaning(s) do the students ascribe to inclusion in mathematics learning and teaching? And what frames students´ meaning(s) of inclusion in mathematics learning and teaching?The first part of this study began with a systematic literature review on the notion of inclusion in mathematics education research, and the search resulted in 1,296 research studies.

4. 13. Environmental preferences among steel stakeholders

   Författare :Stina Alriksson; Marianne Henningsson; Carl-Erik Grip; Anders Roos; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; conjoint analysis; environmental communication; focus group; light weighting; PLS; preferences; Q-methodology; risk perception; steel; stakeholders; Miljövetenskap; Environmental Science;

   Sammanfattning : Emissions of carbon dioxide, dioxins, nitrogen oxides and particulate matter as well as use of non-renewable resources and energy are some important sustainability challenges for the Swedish steel industry. Much effort has been made, mainly by technical solutions, which to a high degree have decreased the emissions during the last 30 years. LÄS MER

5. 14. Epidemiology of injuries in elite football

   Författare :Markus Waldén; Jan Ekstrand; Harald Roos; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Elite; epidemiology; football; injuries; Social medicine; Socialmedicin;

   Sammanfattning : The purpose of this thesis was to study the injury characteristics in elite football, and risk factors for injury with special emphasis on anterior cruciate ligament injury. All five papers followed a prospective design using a standardised methodology. LÄS MER

7. 15. Optical Efficiency of Low-Concentrating Solar Energy Systems with Parabolic Reflectors

   Författare :Maria Brogren; Arne Roos; Björn Karlsson; Andreas Häberle; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Photovoltaic cells; Photovoltaic-thermal systems; Parabolic reflectors; Optical properties; Reflector materials; Optical efficiency; Accelerated ageing; Outdoor ageing; Building-integrated photovoltaics; Teknisk fysik; Engineering physics; Teknisk fysik;

   Sammanfattning : Solar electricity is a promising energy technology for the future, and by using reflectors for concentrating solar radiation onto photovoltaic cells, the cost per produced kWh can be significantly reduced. The optical efficiency of a concentrating system determines the fraction of the incident energy that is transferred to the cells and depends on the optical properties of the system components. LÄS MER
