1. Falls in older people in geriatric care settings : predisposing and precipitating factors
Sammanfattning : Falls and their consequences are a major health problem in the older population, increasing their immobility, morbidity and mortality. This thesis focuses on older people living in geriatric care settings, frail older people who are most prone to suffer falls. LÄS MER
2. On the epidemiology, clinical presentation and transmission of respiratory viral infections
Sammanfattning : Respiratory viral infections encompass a large heterogenous group of pathogens that constitute a major burden of disease globally. The various routes of transmission including airborne spread make them difficult to control. LÄS MER
3. Meteorological impact and transmission errors in outdoor wireless sensor networks
Sammanfattning : Wireless sensor networks have been deployed outdoors ever since their inception. They have been used in areas such as precision farming, tracking wildlife, and monitoring glaciers. These diverse application areas all have different requirements and constraints, shaping the way in which the sensor network communicates. LÄS MER
4. Traffic Emissions of Aerosols
Sammanfattning : Non-exhaust traffic emissions are unregulated, yet the mass emission of non-exhaust particles may be larger than exhaust emissions. In addition, their emission factors (EF) are more uncertain than exhaust emissions. This thesis presents aerosol flux measurements in Stockholm using the eddy covariance method. LÄS MER
5. Regional and local surface ozone variations in relation to meteorological conditions in Sweden
Sammanfattning : Air quality is strongly dependent on meteorological conditions. Atmospheric circulation encapsulates general information about local meteorological variables to some extent, and can serve as an explanatory variable for air quality at a regional or local scale. LÄS MER
