   Sammanfattning : The need to integrate the rapidly growing share of variable renewable energy sources in the power sector requires solutions that are capable of mitigating the intermittent nature of these sources. They are expected to constitute the backbone of the electricity generation system in the coming years in order to reach ambitious goals in terms of energy security and reduction of environmental impact.

5. 4. The sensitivity of Swedish alpine lakes to hydro-climatic changes during the Late Holocene

   Författare :Annika Berntsson; Gunhild Rosqvist; Peter G. Langdon; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; alpine lake sediments; temperature reconstruction; precipitation; catchment erosion; chironomids; oxygen isotopes; XRF core scanning; geomorphology; grain size analysis; kvartärgeologi; Quaternary Geology;

   Sammanfattning : The thesis objective is to use lake sediments to investigate the relationships between chironomids, as proxy for temperature, and δ18O and minerogenic in-wash, as precipitation proxies, in northern Sweden during the Late Holocene. Three lakes along a N–S transect in the Scandes were studied using biological, geochemical and physical sediment properties, together with numerical methods. LÄS MER

7. 5. Divided Exhaust Period on Heavy-Duty Diesel Engines

   Författare :Stefan Gundmalm; Hans-Erik Ångström; Fredrik Ekström; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Due to growing concerns regarding global energy security and environmental sustainability it is becoming increasingly important to increase the energy efficiency of the transport sector. The internal combustion engine will probably continue to be the main propulsion system for road transportation for many years to come. LÄS MER
