  1. 16. Alkali Release and Effects on Biomass Thermal Conversion Processes

    Författare :Yaxin Ge; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Co-conversion; Alkali; Biomass; bed material; thermal conversion; online measurements;

    Sammanfattning : High alkali content is an important feature of biomass, and it has a series of implications for thermal conversion processes. This thesis focuses on the release of alkali during various biomass thermal conversion processes, including biomass pyrolysis, char gasification, co-conversion of different types of biomass, and thermal conversion of biomass mixed with fresh and used bed materials.

  3. 17. Regulation of protein synthesis in human skeletal muscle : separate and combined effects of exercise and amino acids

    Författare :William Apró; Eva Blomstrand; Olav Rooyackers; Hans-Christer Holmberg; Michael Kjaer; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Medicin Teknik; Medicine Technology;

    Sammanfattning : Skeletal muscle is a highly plastic tissue which has the ability to adapt to various forms of external stimuli such as diverse modes of contractile activity. Thus, performance of endurance exercise over several of weeks results in increased oxidative capacity. LÄS MER

  4. 18. Evolutionary implications of acidification: a frog’s eye view

    Författare :Katja Räsänen; Andrew Hendry; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; acid stress; amphibians; local adaptation; maternal effects; maternal investment; Biologi; Biology; Biologi; populationsbiologi; Population Biology;

    Sammanfattning : Understanding the diversity of life is one of the main aims of evolutionary biology, and requires knowledge of the occurrence and causes of adaptive genetic differentiation among geographically distinct populations. Environmental stress caused by acidity may cause strong directional selection in natural populations, but is little explored from an evolutionary perspective. LÄS MER

  5. 19. Cellular effects after exposure to mixed beams of ionizing radiation

    Författare :Elina Staaf; Andrzej Wojcik; Siamak Haghdoost; Eva Forssell-Aronsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ionizing radiation; high LET; low LET; mixed beams; combined exposure; molekylärgenetik; Molecular Genetics;

    Sammanfattning : Mixed beams of ionizing radiation in our environment originate from space, the bedrock and our own houses. Radiotherapy patients treated with boron neutron capture therapy or with high energy photons are also exposed to mixed beams of gamma radiation and neutrons. LÄS MER

  7. 20. Respiratory and cardiovascular effects of exposure to oxidative air pollutants

    Författare :Stefan Barath; Ellinor Ädelroth; Anders Blomberg; E David Newby; M Howard Kipen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Air Pollution; Particulate Matter; Diesel Exhaust; Ozone; Experimental Exposure studies; Luftföroreningar; Partiklar; Disel avgaser; ozon; Experimentella exponerings studier; Internal medicine; Invärtesmedicin; lungmedicin; Lung Medicine; kardiologi; Cardiology; Environmental Science; miljövetenskap;

    Sammanfattning : Background: The negative effects of air pollution on morbidity and mortality have been known since the mid 20th century. The two most well known examples are the Meuse Valley disaster in the 1930’ies and the London black fog in December 1952. LÄS MER
