6. Norovirus Tracing in Environmental and Outbreak Settings - Experiences of waterborne, foodborne and nosocomial transmission
Sammanfattning : 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. LÄS MER
7. Baltic Sea sediments : Source and sink for metal contamination
Sammanfattning : The Baltic Sea sediments record spatial and temporal information about metalsand metalloids (hereafter referred to as metals), which could help to understandthe past and present contamination sinks in different basins. In addition, giventhe expanding anoxic zones in the Baltic Sea, the response of metals to artificialreoxygenation is poorly understood. LÄS MER
8. Computational fluid dynamics application in indoor air quality and health
Sammanfattning : Indoor air quality directly affects the comfort, performance, and well-being of occupants. Indoor pollution can cause immediate or long-term health effects and has been responsible for 4.1% of global deaths in recent decades. LÄS MER
9. Indoor air quality and chemical emissions of organic compounds in newly built low-energy preschools
Sammanfattning : In 2010, the European Union (EU) introduced the “Energy performance of Buildings” directive, which stipulates that all new buildings must reduce their energy consumption by constructing low-energy buildings. This could be achieved by constructing airtight and energy efficient envelopes with functional building materials such as age-resistant plastic films, insulation and different sealing products.

10. Postoperative mediastinitis : risk factors, wound contamination, diagnostic possibilities
Sammanfattning : The aim of these studies has been to investigate different aspects of postoperative mediastinitis. Radiological investigations and biochemical markers of infection and inflammation were examined, risk factors analyzed and spread of bacteria during operation studied. LÄS MER
