16. Physical activity on prescription in primary care. Impact on physical activity level, metabolic health and health-related quality of life, and its cost-effectiveness - a short- and long-term perspective
Sammanfattning : Non-communicable diseases (NCDs) are the leading cause of death globally and one of the major health challenges of the 21st century. In Sweden, NCDs are estimated to account for 90 % of all deaths. LÄS MER
17. Welfare Effects of Transport Policies : an analysis of congestion pricing and infrastructure investments
Sammanfattning : Interactions between the transport market and other distorted markets, such as the labor market, can have a large impact on the overall welfare effect of a road pricing policy or a congestion charge. Many road pricing studies therefore try to incorporate effects from other distorted markets in the analysis. LÄS MER
18. Decision support for sustainable water security
Sammanfattning : Society’s large dependence on water, in combination with climate, socio-economic and demographic changes, places a massive pressure on our freshwater resources. As a result, water crisis, defined as a significant decline in the available quality and quantity of freshwater, is now considered to be among the most critical global risks to society. LÄS MER
19. Research and reflections on European air pollution policy support models
Sammanfattning : European emissions to air of SO2, NOx, PM2.5, NH3 and NMVOC still today cause harm to human health and the environment. These pollutants are associated with the premature death of ~400 000 people annually in the EU (25 000 perished in traffic accidents 2017). Improvements are expected but problems will persist.

20. On Techno-economic Assessment of a Multi-terminal VSC-HVDC in AC Transmission Systems
Sammanfattning : The Voltage Source Converter based Multi-Terminal high voltage Direct Current transmission system (VSC-MTDC) is currently considered as an attractive technical option for increased transmission capacity and improved controllability and flexibility of an electric power grid, thanks to its unique performance characteristics, and the possibility of using the extruded XLPE cables. In the planning process of embedding a VSC-MTDC system into an ac transmission grid, one must assess the potential values in terms of improved energy efficiency, i. LÄS MER
