6. Combined solar and pellet heating systems for single-family houses : How to achieve decreased electricity usage, increased system efficiency and increased solar gains
Sammanfattning : In Sweden, there are about 0.5 million single-family houses that are heated by electricity alone, and rising electricity costs force the conversion to other heating sources such as heat pumps and wood pellet heating systems. Pellet heating systems for single-family houses are currently a strongly growing market. LÄS MER
7. Characterization of the Combustion of Light Alcohols in CI Engines : Performance, Combustion Characteristics and Emissions
Sammanfattning : Alternative fuels for combustion engines are becoming increasingly popular as society is pushing to phase out fossil energy to reduce CO2 emissions. The compression ignition (CI) engine has a high overall efficiency which makes it a valuable option for the transport fleet, despite the well known NOx and soot pollutants it emits. LÄS MER
8. Hörselscreening av en population med utvecklingsstörning : Utvärdering av psykoakustisk testmetod och av OAE-registrering som komplementär metod
Sammanfattning : Populationer med utvecklingsstörning behöver kontinuerlig hörseltestning, men konsensus om lämplig testmetod saknas.Syfte: Syftet med Studie I var att utvärdera psykoakustisk testmetod och med Studie II att utvärdera OAE-registrering som komplementär metod.Studie I. LÄS MER

10. Freshwater methane and carbon dioxide fluxes : Spatio-temporal variability and an integrated assessment of lake and stream emissions in a catchment
Sammanfattning : Freshwater bodies such as lakes and streams release the greenhouse gases methane (CH4) and carbon dioxide (CO2) into the atmosphere. Global freshwater CH4 and CO2 emissions have been estimated to be of a similar magnitude to the global land or ocean carbon sink, and are thus significant components of global carbon budgets. LÄS MER
