  2. 1. Norovirus Tracing in Environmental and Outbreak Settings - Experiences of waterborne, foodborne and nosocomial transmission

    Author : Nancy P Nenonen; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Norovirus; tracing; environment; foodborne; outbreak; waterborne; nosocomial; mussels; GI.1; oysters; GII.4; dust; surfaces; air; molecular epidemiology;

    Abstract : Noroviruses (NoV), a major cause of acute gastroenteritis in hospital settings, also occur as sporadic infections or periodic non-seasonal community outbreaks. Human NoV replicates to high concentration in the intestinal tract, is readily transmitted by the faecal-oral route, hand-to-hand contact, contaminated food and water, and by aerosols. READ MORE

    Abstract : Networks, consisting of nodes and of edges, can be used to model numerous phenomena, e.g, web pages linking to each other or interactions between people in a population. READ MORE

  5. 3. Spatial and temporal dynamics of subarctic birch forest carbon exchange

    Author : Michal Heliasz; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mountain birch; eddy covariance; carbon budget; insect outbreak; forest expansion; temporal variability; spatial variability;

    Abstract : High northern latitudes are of special importance for the global carbon budget as they store large amounts of organic matter in the soil and are expected to be the most strongly affected by climate change. Here we investigate carbon exchange in the subarctic mountain birch forest growing on the limit where tree growth is possible. READ MORE

  6. 4. Using genomics to improve Bacillus anthracis diagnostics and outbreak investigations

    Author : Joakim Ågren; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The bacterium Bacillus anthracis causes the disease anthrax, primarily in herbivores but many mammals are susceptible to the disease. Its infective form is as a dormant spore that can lie in the soil for decades. READ MORE

  7. 5. Towards the Limits – Climate Change Aspects of Life and Health in Northern Sweden : studies of tularemia and regional experiences of changes in the environment
