1. 1. Traditional lime mortar and plaster : Reconstruction with emphasis on durability

   Författare :Kristin Balksten; Tor Broström; Britt-Marie Steenari; Thorborg Konow von; Chalmers Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lime plaster; lime mortar; masonry; craftsmanship; pore structure; frost resistance; historic mortar; Conservation HGO ; Kulturvård HGO ;

   Sammanfattning : Lime mortar and plaster have been investigated with the aim to improve the knowledge on how to make them as durable as before the cement technology was developed. The background was the durability problems experienced for newly produced lime plaster on the medieval churches on the island of Gotland, Sweden. LÄS MER

   Sammanfattning : In designing and erecting buildings in historical times, creating the loadcarrying structure was perhaps the greatest challenge with which the architect and the builder were faced. We encounter structures in which there was a strive to reach vertical heights in the pillars and walls and to extend the horizontal span of the beams and vaults that were built. LÄS MER

4. 3. European Black Grouse : MHC Genetic Diversity and Population Structure

   Författare :Tanja Strand; Jacob Höglund; Helena Westerdahl; David S. Richardson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Major Histocompatibility Complex; BLB; balancing selection; concerted evolution; bottleneck; fragmentation; 3 UTR; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

   Sammanfattning : Black grouse Tetrao tetrix is a bird species composed of large, continuous as well as severely reduced and fragmented populations, making it an optimal species to investigate how genetic diversity is affected by habitat fragmentation. I have focused on genetic diversity in the Major Histocompatibility Complex (MHC) to measure the ability of the black grouse to respond to environmental changes. LÄS MER

5. 4. Structure and function of the yeast mediator tail domain

   Författare :Jenny Béve; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Transcription; RNA polymerase II; Co-activator; Mediator; Tail- module;

   Sammanfattning : Mediator is a co-regulator complex that transduces regulatory information from activators and repressors to the RNA polymerase 11 transcription machinery. Mediator was originally discovered in Saccharomyces cerevisiae and since then Mediator-like complexes have been isolated in a number of organisms including mammals. S. LÄS MER

7. 5. Stadsplanering som professionellt verksamhetsfält : En studie av yrkesgrupper och deras arbete

   Författare :Johan Edman; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociology; occupation; profession; system of professions; professional structure; task area; jurisdiction; Andrew Abbott; urban planning; Sweden; Sociologi; Sociology; Sociologi; sociologi; Sociology;

   Sammanfattning : The aim of this dissertation is to study how the relation between professions and their work is created, developed and reproduced at the interprofessional level. With reference to Andrew Abbott's theory of the system of professions, the relation is analyzed using a conceptual framework that entails three main concepts: professional structure, task area, and jurisdiction.
