   Författare :Anna E. Frost; Mats Leijon; Sandra Eriksson; Irina Temiz; John Ringwood; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linear generator; Wave Power; Poynting s theorem; Partial stator overlap; Permanent-magnet synchronous generator PMSG ; Linear electrical machines; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Sammanfattning : Wave power conversion is one type of renewable electricity generation. Within wave power, there are many different concepts, whereof some utilizes linear generators for converting the energy in the ocean waves into electricity. LÄS MER

3. 2. Power transfer in the air gap of linear generators for wave power

   Författare :Anna E. Frost; Mats Leijon; Sandra Eriksson; Irina Temiz; Thomas Rylander; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linear generator; Wave Power; Air gap; Poynting s theorem; Partial stator-translator overlap; Linear electrical machines; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Sammanfattning : An increased need for electric energy and share of renewable energy is important for a more sustainable future, to which wave power can contribute. Some concepts for wave power use linear generators, and the studies presented here focus on the power transfer and forces in the air gap of linear generators. LÄS MER

4. 3. Towards Good Palliation for Children with Cancer : Recognizing the Family and the Value of Communication

   Författare :Li Jalmsell; Britt-Marie Frost; Mats Hansson; Jan-Inge Henter; Ulrika Kreicbergs; Steven Joffe; Uppsala universitet; []

   Sammanfattning : Pediatric cancer imposes a threat on the child’s life and approximately every fifth child diagnosed with cancer will die due to his or her disease. The overall aim of this thesis was to explore palliative care of children with cancer and bereaved family members. LÄS MER

5. 4. Experimentell bestämning av klimatanpassning hos tall (Pinus silvestris L. och Pinus contorta Dougl.)

   Författare :Mats Hagner; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This paper summarizes the content of three articles published in Studia Forestalia Suecica 80,81,82, 1970.A study of the annual grouuth rhythm on 2-, 3- and 20-year-old Pinus silvestris and 2-year-old Pinus contorta showed that the following methods can be used for experimental assessment of the climatic adaptation of populations and single trees: shoot- and needle elongation, bark colour onterminal, lignification of annual ring and water content of needles.

7. 5. New methods for improving winter road maintenence

   Författare :Mats Riehm; Per-Erik Jansson; Torbjörn Gustavsson; Klas Hansson; Meelis Mölder; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Winter road maintenance; Sensors; Infrared thermometry; Energy efficiency; De-icing salt; Other civil engineering and architecture; Övrig samhällsbyggnadsteknik och arkitektur;

   Sammanfattning : Winter road maintenance activities are crucial for maintaining the accessibility and traffic safety of the road network during winters. Common winter road maintenance activities include plowing and the use of de-icing agents (e.g. NaCl) to avoid freezing. LÄS MER
