1. Health systems bottlenecks and evidence-based district health planning : Experiences from the district health system in Uganda
Sammanfattning : In low-income countries where maternal and child mortality remains high, there is limited use of context-specific evidence for decision making and prioritization of interventions in the planning process at the sub-national level, such as the district level. Knowledge on the utility of tools and interventions to promote use of district-specific evidence in the planning process is limited, yet it could contribute to the prioritization of high-impact interventions for women and children.

2. Low-temperature District Heating : Various Aspects of Fourth-generation Systems
Sammanfattning : With decreasing heat demand and less availability of high-temperature heat supply in future energy systems, the current district heating systems may experience increased competition on the heat market. A viable option to mitigate increasing competition is to operate systems with lower temperature levels, and the most conceivable way to achieve lower temperature levels is to decrease return temperatures.

3. Small District Heating Systems
Sammanfattning : The objective of this work is to identify, from an economical point of view, the optimal system design and operation strategy for the district heating of a small residential area. The applied methodology is an overall approach on the heat distribution system, the house connection and the space heating system in the building, i.e. LÄS MER
4. District Heating and CHP : Local Possibilities for Global Climate Change Mitigation
Sammanfattning : Global warming, in combination with increasing energy demand and higher energy prices, makes it necessary to change the energy use. To secure the energy supply and to develop sustainable societies, construction of energy-efficient systems is at the same time most vital. LÄS MER
5. Heat driven cooling in district energy systems
Sammanfattning : Abstract The threat of global warming, caused by increasingemissions of carbon dioxide (CO2), is one reason why cooling supply systems mustwork more efficiently in the world today. An increasing share,currently between 10 and 20%, of the global output ofelectricity is consumed to produce cooling. LÄS MER
