  3. 2. Historical Urban Agriculture : Food Production and Access to Land in Swedish Towns before 1900

    Författare :Annika Björklund; Mats Widgren; Johannes Renes; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; urban agriculture; urban history; urban geography; Sweden; town; food production; food consumption; Uppsala; historical geography; land allocation; cadastral maps; urban land-use; Human geography; Kulturgeografi; Human Geography; kulturgeografi;

    Sammanfattning : This doctoral thesis analyses the role of historical urban agriculture in a long-time perspective, through a combination of overarching surveys of Swedish towns and detailed studies of one town – Uppsala in east-central Sweden. The study shows how agricultural land – town land – of various sizes was donated to towns repeatedly during medieval times and in the 16th and 17th centuries. LÄS MER

  4. 3. Signal Processing for Radar with Array Antennas and for Radar with Micro-Doppler Measurements

    Författare :Svante Björklund; Mats Pettersson; Ingvar Claesson; Ulrich Nickel; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radar; signal processing; array antenna; subarray; clutter; jamming; interference; direction of arrival estimation; security; micro-Doppler; feature extraction; classification;

    Sammanfattning : Radar (RAdio Detection And Ranging) uses radio waves to detect the presence of a target and measure its position and other properties. This sensor has found many civilian and military applications due to advantages such as possible large surveillance areas and operation day and night and in all weather. LÄS MER

  5. 4. Operationalizing Industrial Ecology in the Waste Sector : Roles and tactics for circular value innovation

    Författare :Graham Aid; Nils Brandt; Monika Olsson; Maria Malmström; Leenard Baas; Stefan Anderberg; Mats Eklund; Anna Björklund; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The take-make-waste approach to resource management in human production and consumption systems is contributing to a variety of environmental and social problems worldwide. Additionally, as the world’s population and affluence increase, so do the negative impacts of poor resource management. LÄS MER

  7. 5. Conservation Genetics of the Eurasian Otter in Sweden

    Författare :Johanna Arrendal; Mats Björklund; Carles Vilà; Ralph Tiedemann; Uppsala universitet; []
    Nyckelord :Ecology; in situ conservation; individual identification; microsatellites; mtDNA; noninvasive genetic sampling; population dynamics; population size; PVA; restocking; Ekologi; Lutra lutra;

    Sammanfattning : In this thesis, molecular genetic methods were used to study a threatened species, the Eurasian otter. Estimates of population size and population dynamics parameters were obtained, the genetic effects of a restocking program was evaluated, and a population viability analysis was conducted to assess which demographic parameters are most important for the future viability of an otter population.
