    Sammanfattning : The present ethnography documents computer activities in everyday life. The data consist of video recordings, interviews and field notes, documenting (i) 16 students in a seventh grade class in a computer room and other school settings and (ii) 22 children, interacting with siblings, friends and parents in home settings.

  2. 22. Calcium signaling and network activity : mathematical modeling and molecular mechanisms

    Författare :Erik Smedler; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The calcium (Ca2+) ion is a versatile second messenger present in all cells. It is involved in such diverse processes as cell division, differentiation, vesicle transport and muscle contraction. Its widespread applicability is partially explained by its wide temporal and spatial dynamics. LÄS MER

  3. 23. Economic Aspects of Fuel Cell-Based Stationary Energy Systems

    Författare :Suat Sevencan; Göran Lindbergh; Lechtenböhmer Stefan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel cells; niche market; stationary applications; feasibility; multi-generation; Chemical Engineering; Kemiteknik;

    Sammanfattning : It is evident that human activity has an important impact on climate. Constantly increasing energy demand is one of the biggest causes of climate change. The fifth assessment report of the Inter-governmental panel on climate change states that decarbonisation of electricity generation is a key component of climate change mitigation. LÄS MER

  4. 24. Human Endogenous Retroviruses: Studies on Transcriptional Activity and Genetic Variability

    Författare :Patrik Medstrand; Malmö Klinisk virologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; virology; bacteriology; HERVs; Human endogenous retrovirus sequences; reverse transcriptase; Microbiology; differential RNA expression.; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Endogenous retroviruses (ERVs) are believed to be remains of germ-line infections that have become fixed in the population. They are involved in pathophysiological conditions, in mechanisms leading to infection protection, and directly in the physiology of the organism by participating in the regulation of cellular gene expression.

  5. 25. Cursed complexity. Computational properties of subcortical neuronal microcircuitry in sensorimotor control

    Författare :Anton Spanne; Hjärnans sensorimotoriska funktioner; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; spike firing statistics; spontaneous activity; sensorimotor control; tactile processing; cuneate nucleus; sparse coding; spinal border cells; cerebellum;

    Sammanfattning : One of the big obstacles for understanding the nervous system is its inherent complexity. It poses problems when interpreting both experimental and theoretical studies since we are currently forced to consider only reduced variants of the actual circuitry of the brain. LÄS MER
