    Författare :Eva Hartell; Inga-Britt Skogh; Lena Gumaelius; Richard Kimbell; Kay Stables; KTH; []
    Nyckelord :technology education; primary education; assessment; classroom assessment; formative assessment; assessment for learning; self-efficacy; e-portfolio; e-assessment; engineering education; STEM; teknikundervisning; teknikdidaktik; formativ bedömning; bedömning; grundskola; klassrumsbedömning; bedömning för lärande; betyg; vurdering; vurdering for laring; Teknikvetenskapens lärande och kommunikation; Education and Communication in the Technological Sciences;

    Sammanfattning : This thesis focuses on teachers’ assessment practices in primary and lower secondary schools for technology education (Sv. Teknik). It is grounded in my prior experience as a teacher but also addresses the national and international research fields of technology education and assessment. LÄS MER

  3. 2. Computational approaches for in-depth analysis of cDNA sequence tags

    Författare :Per Unneberg; Joakim Lundberg; Leif Andersson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; cDNA; EST; gene expression; SNP; SAGE; polymorphism; Bioteknik; Bioengineering; Bioteknik;

    Sammanfattning : Major recent improvements in biotechnology have led to an accelerated production of DNA sequences. The completion of the human genome sequence, along with the genomes of more than two hundred other species, has marked the arrival of the genome era. The ultimate goal is to understand the structure and function of genomes and their genes. LÄS MER

  4. 3. Molecular Phylogenetics of Mammals

    Författare :Morgan Kullberg; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Genetics; EST; divergence times; phylogenomics; phylogenetic reconstruction; Mammals; Eutheria; cytogenetics; Genetik; cytogenetik;

    Sammanfattning : In this thesis, the phylogenetic relationships of the Mammalia have been studied at various levels. Different sources of genetic information have been evaluated and used as phylogenetic markers. These include the well-known mitochondrial genome, cDNA from housekeeping genes and expressed sequence tags from nuclear genes. LÄS MER

  5. 4. Cold Acclimation in oats and other plants: Dissecting low temperature responses using a comparative genomic approach

    Författare :Marcus Bräutigam; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cold acclimation; oat; EST; microarray; transcriptome; chilling; freezing; rice; Arabidopsis; TILLING; mutation;

    Sammanfattning : Cold acclimation protects plants from temperate regions of the world from the deleterious effects of low and freezing temperatures. This is through a series of transcriptional, regulatory and metabolic changes that enable continued growth and survival. LÄS MER

  7. 5. A Genetic Survey of the Pathogenic Parasite Trypanosoma cruzi

    Författare :Anh-Nhi Tran; Lena Åslund; John Kelly; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; Trypanosoma cruzi; Chagas ; gene discovery; EST; sequencing; DGC3; repeats; gene family; CL Brener; trypanothione synthetase; TcTRS locus; alleles; polymorphism; RNA-binding protein; TcPTB; stage-specific expression; Genetik; Genetics; Genetik; medicinsk genetik; Medical Genetics;

    Sammanfattning : Trypanosoma cruzi, the causative agent of Chagas´ disease, is an evolutionarily ancient species with distinct biological and immunological characteristics. A fundamental understanding of the basic biology of the parasite is necessary in order to develop reliable therapeutic and prophylactic agents against T. cruzi. We have, as a part of the T. LÄS MER
