2. Firefighters' physical work capacity
Abstract : The overall aim of this thesis was to identify valid, simple, and inexpensive physical tests that can be used for evaluation of firefighters’ physical work capacity. Paper I included fulltime- and part-time firefighters (n = 193), aged 20-60 years. READ MORE

3. Lithium-ion Battery Safety - Assessment by Abuse Testing, Fluoride Gas Emissions and Fire Propagation
Abstract : Lithium-ion batteries offer high energy and power densities as well as long life time but have a more narrow stability window compared to other battery types and contain reactive and flammable materials. In case of overheating the battery cell can release gas (vent) and, at temperatures of about 150-200 °C, a so called thermal runaway can occur, that is a rapid self-heated temperature increase which is typically accompanied with a large release of smoke and gas, fire and a potential cell case explosion or gas explosion.

4. Physical Training and Testing in Patients with Chronic Obstructive Pulmonary Disease (COPD)
Abstract : The overall aims of the studies were to investigate the effects of different training modalities on exercise capacity and health-related quality of life (HRQoL) in patients with moderate or severe COPD and, further, to explore two of the physical tests used in pulmonary rehabilitation.In study I, the 12-minute walking distance (12MWD) did not increase on retesting in patients with exercise-induced hypoxemia (EIH) whereas 12MWD increased significantly on retesting in the non-EIH patients.

5. Cross-scale perspectives on heterogeneity in Swedish boreal forests
Abstract : Maintaining species diversity, ecosystem functioning, and socioeconomic values requires continued ecosystem heterogeneity across scales. This thesis aims to bridge gaps between ecological theory, environmental goals, and practical application of sustainable forest management needed to maintain such heterogeneity. READ MORE
