    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The study presented in this licentiate thesis explores the student perception of systematically varied lessons, a specific lesson design and exploratory method of teaching mathematics in comprehensive school.Two 9th grade classes are taught in the curriculum defined mathematical core content sections of algebra and mathematical relationships and rate of change but by two different methods.

  3. 2. Development and Application of Reactor Noise Diagnostics

    Författare :Joakim K.-H. Karlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; BWR stability; noise decomposition; reactor noise; control rod vibrations; core barrel vibration; density wave oscillations; noise diagnostics; PWR noise; localisation; channel instability;

    Sammanfattning : A number of problems in reactor noise diagnostics have been investigated within the framework of the present thesis. The six papers presented cover three relatively different areas, namely the use of analytical calculations of the neutron noise in simple reactor models, some aspects of boiling water reactor (BWR) stability and diagnostics of core barrel motion in pressurized water reactors (PWRs).

  4. 3. Gene Expression Patterns in a Rat Model of Human Endometrial Adenocarcinoma

    Författare :Sandra Karlsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rat; complex disease; Endometrial adenocarcinoma; gene expression profiling; cDNA microarrays; candidate genes; Molecular biology; Medical sciences;

    Sammanfattning : Endometrial cancer develops from the endometrium of the uterus and is the most common pelvic malignancy diagnosed in women in the western society. Similar to all cancer diseases, endometrial cancer is a disorder that results from complex patterns of genetic and epigenetic alterations involved in the malignant transformation. LÄS MER

  5. 4. Survival of Cultured and Grafted Embryonic Dopaminergic Neurones - Effects of hypothermia and prevention of oxidative stress

    Författare :Jenny Karlsson; Neurobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; 6-OHDA; lazaroid; PBN; brain; transplant; Parkinson s disease; dopamine; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Transplantation of embryonic dopaminergic neurones can ameliorate symptoms in Parkinson’s disease, but a major obstacle for clinical transplantations to overcome is the low survival (typically 5-10%) of implanted nigral neurones. If cell death in nigral grafts can be prevented, less embryonic tissue would be needed per transplantation session and hence more patients could receive intracerebral grafts as a therapy for Parkinson’s disease.

  7. 5. The MHC genes: variation and impact on life-history traits in house sparrwos

    Författare :Maria Karlsson; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MHC-I; house sparrow; 454-amplicon sequencing; cDNA; functional clustering; trans-species evolution; nestling survival; mate-choice;

    Sammanfattning : In birds the major histocompatibility complex (MHC) organization differs both among and within orders. Galliformes often have simple arrangements with few transcribed MHC genes whilst many songbirds (Passeriformes) have a complex arrangement with many MHC genes and also presence of pseudo-genes.
