  1. 1. Novel methods for mapping genome organization and genome fragility in the 3D space of the nucleus

    Författare :Tomasz Kallas; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : For over a century, scientists have been trying to understand how the DNA molecule that is so tightly packed in the micro space of the nucleus sustains critical cellular processes such as transcription, replication or the maintenance of genetic information. Despite the huge effort of researchers around the world, we know relatively little. LÄS MER

  3. 2. Heterologous expression and characterization of xyloglucan endotransglycosylases from Populus tremula x tremuloides

    Författare :Åsa Kallas; KTH; []
    Nyckelord :xyloglucan endotransglycosylase; transglycosylation; hybrid aspen; cell expansion; heterologous expression; Pichia pastoris; N-glycosylation; X-ray crystallography;

    Sammanfattning : Xyloglucan endotransglycosylases (XETs) are enzymes involvedin the reorganization of the primary cell wall. This thesisdescribes several aspects of XET16A from hybrid aspen (Populustremula x tremuloides). The gene was isolated from the hybridaspen cDNA library and the protein was expressed heterologouslyin the methylotrophic yeast Pichia pastoris. LÄS MER

  4. 3. Heterologous expression, characterization and applications of carbohydrate active enzymes and binding modules

    Författare :Åsa Kallas; Tuula T. Teeri; Edward A. Bayer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Populus; xyloglucan endotransglycosylase; carbohydrate binding modules; endo- 1; 4 -b-xylanase; Escherichia coli; Pichia pastoris; N-glycosylation; fiber analysis; Bioengineering; Bioteknik; Wood fibre and forest products; Träfiber- och virkeslära;

    Sammanfattning : Wood and wood products are of great economical and environmental importance, both in Sweden and globally. Biotechnology can be used both for achieving raw material of improved quality and for industrial processes such as biobleaching. LÄS MER

  5. 4. -Måste det här vara som en väckelserörelse? : en studie om (det som kallas) entreprenöriellt lärande i grundskolan, utifrån Basil Bernsteins begreppsapparat

    Författare :Monika Diehl; Eva Leffler; Joakim Lindgren; Maj Asplund Carlsson; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Entrepreneurial learning; lower secondary school; recontextualisation; Basil Bernstein; education; teaching; learning; assessment; classification; framing; Entreprenöriellt lärande; grundskolan; rekontextualisering; Basil Bernstein; utbildning; undervisning; lärande; bedömning; klassifikation; inramning; education; pedagogik;

    Sammanfattning : The aim of this compilation thesis is to describe prerequisites for what, in a Swedish educational context, is often called ‘entrepreneurial learning’ and to examine the possible influence that this has on school practice. The study was carried out in two lower secondary schools and was guided by the following two research questions. LÄS MER

  7. 5. Är det detta som kallas postmodernism? : En studie i Katarina Frostensons och Stig Larssons diktning

    Författare :Victor Malm; Litteraturvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; Postmodernism; Postmodernitet; Katarina Frostenson; Stig Larsson; Poesi;

    Sammanfattning : During the 1980s the word ’postmodernism’ was inserted into the dicourse of Swedish literature in a curious way. Even though both writers and critics found the word bewildering – or deemed it a buzzword devoid of meaning – it sparked fierce debates. LÄS MER
