  1. 1. Temporal climate impacts of using willow and logging residues for district heating in Sweden

    Author : Torun Hammar; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES;

    Abstract : Using bioenergy to replace fossil fuels has been adopted as a climate mitigation measure, since less greenhouse gases are expected to be released into the atmosphere. In Sweden, the share of bioenergy is relative high (about 23% of total consumption including peat), with a relatively large proportion originating from domestically produced forest biomass.

  2. 2. Impact of smallholder management strategies on sow and piglet condition and performance

    Author : Ammaly Phengvilaysouk; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; AGRICULTURAL SCIENCES;

    Abstract : This thesis examined the impact of management strategies on performance and condition of sows and piglets owned by smallholder farmers in Lao PDR. A survey was performed on smallholder pig farms (SHPF) and larger-scale pig farms (LSPF) to identify factors with potential to improve performance. READ MORE

  3. 3. Seasonal snow storage for cooling applications

    Author : Kjell Skogsberg; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : Seasonal snow storage for cooling applications is an ancient technique now being revived in different parts of the world. From June 2000 the first Swedish large-scale snow cooling plant provides for comfort cooling at the hospital in Sundsvall. The snow is thermally insulated by a 0. READ MORE

  4. 4. Seasonal turnover in groundwater

    Author : Maria Engström; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : This Licentiate Thesis presents a new approach of understanding leakage in agricultural land. Former studies concentrate on long term measurement of different pollutants in nearby watercourses and streams. The new approach is so far only numerically performed, but will soon be complemented by laboratory tests and field measurements. READ MORE

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

    Abstract : 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. READ MORE
