  5. 3. Combined solar and pellet heating systems for single-family houses : How to achieve decreased electricity usage, increased system efficiency and increased solar gains

    Author : Tomas Persson; Per Lundqvist; Simon Furbo; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pellet; pelleteldning; kamin; panna; solvärmesystem; varmvattenberedning; systemutformning; småhus; elbesparing; verkningsgrad; emissioner; rökgasförluster; skorstensförlust; diskmaskin; tvättmaskin; Thermal energy engineering;

    Abstract : 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. READ MORE

  6. 4. Pictorial Primates: A Search for Iconic Abilities in Great Apes

    Abstract : Pictures and other iconic media are used extensively in psychological experiments on nonhuman primate perception, categorisation, etc. They are also used in everyday interaction with primates, and as pure entertainment. READ MORE

  7. 5. Molecular mechanisms in actinorhizal symbioses

    Author : Tomas Persson; Katharina Pawlowski; Helge Küster; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant Physiology; växtfysiologi;

    Abstract : The symbiosis between the nitrogen fixing acinobacterium Frankia and its actinorhizal host plant is very old and their co-evolution has shaped their niche in the environment. Nitrogen is most often the limiting element in soil, and symbiotic plants can, with the help of their micrsymbionts, compete in an efficient way. READ MORE
