  1. 1. Modeling lichen performance in relation to climate : scaling from thalli to landscapes

    Sammanfattning : Lichens can colonize nearly all terrestrial habitats on earth and are functionally important in many ecosystems. Being poikilohydric, their active growth periods are restricted to periods when the thallus is hydrated from atmospheric water sources, such as rain, fog and high relative humidity. LÄS MER

  2. 2. Energy Management in Large scale Solar Buildings : The Closed Greenhouse Concept

    Författare :Amir Vadiee; Viktoria Martin; Philip Griffiths; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Energy Storage; Energy Saving; Thermoeconomic Assessment; Energy Management Scenario; Micro Climate Control; Solar Building; Closed Greenhouse; SRA - Energy; SRA - Energi;

    Sammanfattning : Sustainability has been at the centre of global attention for decades. One of the most challenging areas toward sustainability is the agricultural sector. Here, the commercial greenhouse is one of the most effective cultivation methods with a yield per cultivated area up to 10 times higher than for open land farming. LÄS MER

  3. 3. Methods for determination of moisture conditions in wood exposed to high moisture levels

    Författare :Maria Fredriksson; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This study is a start to investigate the relationship between micro climate, i.e. the climate at the wood surface, and the wood moisture content. The micro climate is affected by the construction design; if water gets trapped in joints and stays on wood surfaces, the time during which water is absorbed by the wood increases. LÄS MER

  4. 4. Strategic use of straw at farrowing : effects on behaviour, health and production in sows and piglets

    Författare :Rebecka Westin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : According to EU-regulations, sows should be provided with suitable manipulable material, this in order to meet their behavioural needs. "Strategic use of straw at farrowing" means that loose housed sows are provided with 15-20 kg of chopped straw once at 2 days prior to the calculated date of farrowing. LÄS MER
