Popular Abstract in Swedish Småbarnsskolan. Vad hände och varför? En sekellång historia studerad med fokus på förändring av pedagogisk verksamhet från 1833 och framåt. I denna bok tecknas en bild av småbarnsskolan som pedagogisk företeelse i Sverige. Den första småbarnsskolan inrättades 1833 och i kölvattnet följde ett trettiotal. Flera småbarnsskolor överlevde sekelskiftet och behöll sina beteckSome fields in the research about the history of childcare in the nineteenth century in Sweden is lacking. In popular textbooks infant schools (småbarnsskolor) are thought of and described as a pedagogical and social activity, while a later phenomenon, the nursery schools, seemed to lack all pedagogical insight, care-taking was exclusively at hand. I have questioned this dichotomy. What happened t

Due to its gentle and high resolving power, chromatography is the work horse within protein separation. Still it is an expensive method due to low productivity, diluted product streams, large waste streams and expensive support material. This limits its potential use to areas of high price products. Therefore there is a clear interest to make the technology cheaper to use both for the existing pha

This thesis deals primarily with the production of written texts by adults with reading and writing difficulties. Their writing is analysed from three different aspects: error analysis, non-error-oriented text analysis and analysis of the production process. These studies are based on data from on-line recordings of writing. The main question is how the written language production of adults with r

Hemicellulosic materials are among the most abundant renewable resources on earth, but have not yet found any broad application. However, if a cost effective extraction method is developed, hemicelluloses have the potential to be utilized to a much larger extent in the future. Ultrafiltration (UF) is a low energy demanding separation process that can be used to concentrate and purify hemicellulose

The main objective was to compare short wave radiation from Thorn lamp to solar radiation. In sun all manikin front zones get more or less evenly radiated but in the lab the radiated power reaches some zones more than others. Tests were carried out on the thermal manikin Tore under clear sky in a building corner facing the sun. The manikin was turned so that in the end of each trial the sun faced

The differentiation between expression and content is fundamental in the concept of signs. Even if the notions of signs are often revised, due partly to the attraction of a semiotic approach from markedly disparate objects of study, a common apprehension of the distinctive character of meanings by sign is its dual nature.

Popular Abstract in Swedish Vårärt (Lathyrus vernus) är en skogsväxt som tillhör familjen ärtväxter (Fabaceae). Den förekommer hos oss i södra och mellersta Sverige och har sin nordligaste utbredning vid Höga kusten, där den förekommer i geografiskt isolerade populationer på sydsluttningar med gynnsamt klimat. I övrigt har vårärten sitt utbredningscentrum i centrala och östra Europa. Med denna avhIn the present thesis, I investigated patterns of genetic variation in the forest herb Lathyrus vernus (Fabaceae), using plant material from different-sized populations representing three geographically separated regions: central Europe, southern and central Sweden. My studies included presumably neutral or weakly selected characters (allozymes and leaflet shape) as well as characters that should

Popular Abstract in Swedish Exponeringsskattning för att hindra uppkomst av belastningsskador Skador på muskler som uppkommer av olämpliga arbetsrörelser och arbetsställningar (belastningsskador) utgör ett stort problem i alla industrialiserade länder. Definitionen av vad som innefattas i begreppet arbetsskada varierar mellan olika länder, varför det är svårt att göra jämförelser. Kostnader för arWork-related musculoskeletal disorders of shoulder/neck are a major and increasing problem. Beside the pain, they involve high cost for the employer and society. The total expenditure for the musculoskeletal disorders of the neck and upper limb have been estimated to 0.5-2.0% of the Gross National Product (GNP) in the Nordic countries. Due to the lack of precise knowledge of exposure/response rela
