   Sammanfattning : The overall aim of this thesis was to explore and describe schoolchildren's selfreported-health based on the Health Dialogue concept as well as to identify healthindicators and their possible associations in the perspective of 6 to 16 year-olds,and to provide an analysis of school nurses´ experiences of using the HealthDialogue concept, in the County of Västernorrland. The thesis was based on fourstudies (I-IV). LÄS MER

3. 17. Energy Management in Large scale Solar Buildings : The Closed Greenhouse Concept

   Författare :Amir Vadiee; Viktoria Martin; Philip Griffiths; KTH; []

   Sammanfattning : The dynamic business environment is characterized by short-term and long- term uncertainties in the business processes, combined with a short-term focus on meeting customers' and share-holders' requirements. Therefore, making correct decisions in a dynamic business environ-ment is a major challenge for production plant engineers and managers all over the world. LÄS MER

5. 19. Saving Energy in Construction Machinery using Displacement Control Hydraulics : Concept Realization and Validation

   Författare :Kim Heybroek; Jan-Ove Palmberg; Jochen Pohl; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik;

   Sammanfattning : In the sector of mobile hydraulics, valve controlled systems are predominant. In these systems the load force and speed are adjusted by control valves. In machines where multiple drives are used in parallel at extremely varying loads the energy efficiency of such systems is often compromised over large working regions. LÄS MER

7. 20. Low-Cost, Environmentally Friendly Electric Double-Layer Capacitors : Concept, Materials and Production

   Författare :Britta Andres; Håkan Olin; Christina Dahlström; Jonas Örtegren; Renyun Zhang; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electric Double-Layer Capacitor; Graphite; Cellulose Nanofibers; Large-Scale; Mass Balancing; Metal-Free;

   Sammanfattning : Today’s society is currently performing an exit from fossilfuel energy sources. The change to sustainable alternativesrequires inexpensive and environmentally friendly energy storagedevices. However, most current devices contain expensive,rare or toxic materials. These materials must be replaced bylow-cost, abundant, nontoxic components. LÄS MER
