    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; history; narrative texts; semiotic resources; Middle school; textbooks; Scandinavian Languages; nordiska språk;

    Sammanfattning : The aim of this thesis is to study the conditions surrounding young students’ text production in the subject of History. The study, which was performed within a class in grade 4, describes a project where the students produced individual books about the Middle Ages. LÄS MER

  3. 2. Expression and regulation of Rad51 in human cells

    Författare :Jenny Flygare; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :HsRad51 recombination; DNA repair; cell cycle; apoptosis; caspase-3; hybridization array;

    Sammanfattning : Double strand breaks (DSBs) can be caused by exogenous DNA damaging agents or by endogenous processes, and may lead to chromosomal breakage and rearrangement resulting in apoptosis or tumorigenesis. The repair of DSBs in higher eukaryotes is to a large extent accomplished by homologous recombination (HR), a process in which DNA from a complementary strand is used as a template for repair synthesis.

  4. 3. Nitrification and Nitrifying Bacterial Communities in Coniferous Forest Soils : Effects of Liming and Clear-Cutting

    Författare :Jenny Bäckman; Wietse de Boer; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : This thesis deals with the effects of liming and clear-cutting on nitrification in hemi-boreal and northern temperate coniferous forest soils. The approach has been to study both the potential nitrification and the community structure of the ammonia-oxidising bacteria, which carry out the first step of autotrophic nitrification. LÄS MER

  5. 4. Multifaceted adhesion properties of Helicobacter pylori in promotion of gastric disease

    Författare :Jenny Nordén; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Helicobacter pylori is a Gram-negative spiral-shaped bacteria that resides in the gastric mucosa and adheres to the epithelial lining of the human stomach. H. pylori adhesion mediates inflammation of the epithelium, which can lead to more severe diseases such as chronic active gastritis and gastric carcinoma. LÄS MER

  7. 5. Peptidoglycan regulation of Drosophila immunity

    Författare :Jenny Karlsson; Håkan Steiner; Kenneth Söderhäll; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi; molekylärgenetik; Molecular Genetics;

    Sammanfattning : Innate immunity is an ancient defense system that distinguishes between self and non self and is present in both vertebrates and invertebrates. Peptidoglycan (PGN), a cell wall component shared by both gram-negative and gram-positive bacteria, is the major recognition molecule for the detection of bacteria in Drosophila. LÄS MER
