1. 1. Solar Thermal Collectors at High Latitudes : Design and performance of non-tracking concentrators

   Författare :Monika Adsten; Manuel Collares-Pereira; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Solar thermal collectors; concentrators; CPC; high latitudes; Materialvetenskap; Solfångare; koncentratorer; höga latituder; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

   Sammanfattning : Solar thermal collectors at high latitudes have been studied, with emphasis on concentrating collectors. A novel design of concentrating collector, the Maximum Reflector Collector (MaReCo), especially designed for high latitudes, has been investigated optically and thermally. LÄS MER

3. 2. Numerical studies of current profile control in the reversed-field pinch

   Författare :Jon-Erik Dahlin; Jan Scheffel; Roberto Paccagnella; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Reversed-Field Pinch; RFP; Current Profile Control; CPC; DEBS; DEBSP; active control; feedback; MHD.; Fusion; Fusion;

   Sammanfattning : The Reversed-Field Pinch (RFP) is one of the major alternatives for realizing energy production from thermonuclear fusion. Compared to alternative configurations (such as the tokamak and the stellarator) it has some advantages that suggest that an RFP reactor may be more economic. LÄS MER

4. 3. Putting words to child physical abuse : Possible consequences, the process of disclosure, and effects of treatment. From children’s perspectives

   Författare :Johanna Thulin; Cecilia Kjellgren; Doris Nilsson; Eriksson Maria; Linnéuniversitetet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; child physical abuse; disclosure; participation; CPC-CBT; intervention; Socialt arbete; Social Work;

   Sammanfattning : Aim: The overall aim of the thesis is to explore the experiences and possible consequences concerning reported health and relations between a parent perpetrator of physical child abuse and the children who are victims of the parental physical abuse, the children’s thoughts when disclosing the abuse, and the impact of an intervention designed to support these children in a Swedish context – Combined Parent Child Cognitive Behavioral Therapy (CPC-CBT). Methods: This thesis has a mix-method design. LÄS MER

7. 5. Retrofitted Solar Domestic Hot Water System for Single-Family Electrically-Heated Houses: Development and testing

   Författare :Ricardo Bernardo; Institutionen för arkitektur och byggd miljö; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar domestic hot water; retrofitting; single family electrically heated houses; high solar fraction; photovoltaic thermal concentrating hybrids; PVT; parabolic reflectors; CPC thermal collector.;

   Sammanfattning : In Sweden, there are roughly half a million single family houses that use electric heating for both domestic hot water production and space heating. Since electricity is the most expensive energy source in Sweden, it is interesting to install a high solar fraction solar thermal system to reduce the energy use in these houses. LÄS MER
