1. 31. Självägarområdenas egenart : Jämtland och andra områden i Skandinavien med småskaligt jordägande 900–1500

   Författare :Olof Holm; Leif Runefelt; Olle Ferm; Stefan Brink; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; landownership; freeholders; trade; social structure; Scandinavia; Jämtland; Viking Age; Middle Ages; History; historia;

   Sammanfattning : This thesis takes its departure from the fact that in the 16th century there were some regions in Scandinavia where almost all land was held by freeholders, while in other regions large areas of land were held by landlords. The aim of the study is to determine which factors had been decisive in the development of this regional variation. LÄS MER

3. 32. Parents, children and their families : living arrangements of old people in the XIX century, Sundsvall region, Sweden

   Författare :Leonardo Fusè; Sören Edvinsson; Hans Nilsson; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; 19th century; Demographic transition; Sundsvall; Sweden; Family planning; Household structure; Industrialization; Life-course analysis; Living arrangements; Old age; Social history; Demography; Demografi;

   Sammanfattning : This study deals with the intergenerational coresidence during the nineteenth century. The main focus is placed on the possible differences in the coresidences among parents and children and whether demographic transition and industrialization changed this relation. LÄS MER

4. 33. Structure of Hardened Cement-Fly Ash Systems and Their Related Properties

   Författare :Aimin Xu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water vapour sorption isotherms; thermogravity analysis; mortar; scanning electron microscopy; differential thermal analysis; X-ray diffraction analysis; fly ash; pore structure; microstructure; cement paste;

   Sammanfattning : The influence of fly ash on the pore structure and microstructure of cement paste and mortar has been investigated. The methods applied include water vapour sorption isotherms, scanning electron microscopy, X-ray diffraction analysis and thermogravity/differential thermal analysis. LÄS MER

5. 34. Fritidshemmets läroplan under förhandling : formulering, tolkning och realisering av del fyra i Lgr 11

   Författare :Maria Norqvist; Maria Rönnlund; Birgit Andersson; Helene Elvstrand; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Swedish school-age educare; leisure-time centre; classification; framing; pedagogical code; frame factors; curriculum arenas; power relations; pedagogiskt arbete; educational work;

   Sammanfattning : The aim of this study is to contribute with knowledge about the negotiations behind formulating part four of the Swedish curriculum Lgr 11, with a focus on pedagogical codes and power relations between school and school-age educare (SAE), as well as the negotiations that are expressed when the curriculum text is interpreted and realised in SAE practice.To reach this aim, parts of Bernstein’s code theory is used.

7. 35. Nanostructuring and Age Hardening in TiSCN, ZrAlN, and TiAlN Thin Films

   Författare :Lars Johnson; Lars Hultman; Axel Flink; Linköpings universitet; []
   Nyckelord :thin films; age hardening; spinodal decomposition; TiSiCN; ZrAlN; TiAlN; Transmission electron microscopy; Atom probe tomography; NATURAL SCIENCES; NATURVETENSKAP;

   Sammanfattning : This thesis explores nanostructuring in TiSiCN, ZrAlN, and TiAlN thin films deposited by cathodic arc evaporation onto cemented carbide substrates, with intended applications for cutting tools. The three systems were found to exhibit age hardening upon annealing, by different mechanisms, into the superhard regime (≥30 GPa), as determined by a combination of electron microscopy, X-ray diffraction, atom probe tomography, erda, and nanoindentation tech- niques.
