    Sammanfattning : This thesis examines the use of various osseous raw materials in craft activities in the Mälaren region during the Middle Ages. Places studied are: Birka, Sigtuna, Nyköping, Strängnäs and Uppsala. The aim is to capture both chronological and spatial changes in the use of osseous raw materials. LÄS MER

  3. 2. Designing out waste - Exploring barriers for material recirculation

    Författare :Isabel Ordonez Pizarro; Chalmers tekniska högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste sorting; sustainable development; Water; Waste; Urban; waste management; Resources; resource recovery; ​Recycling; designing with waste; recycling;

    Sammanfattning : This doctoral thesis has investigated what hinders material recirculation in society, to later suggest possible ways to support material recirculation in the future. Since material recirculation is proposed as a way to use waste materials for new production, it was deemed relevant to investigate two separate case studies that enabled recirculation from production systems and waste management.

  4. 3. No time to waste : Pre-hospital actions and time delays in patients with ST elevation myocardial infarction – temporal trends and prognostic impact on short- and long-term survival

    Författare :Maria Ericsson; Ingela Thylén; Anna Strömberg; Sofia Sederholm Lawesson; Emil Hagström; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background: In ST-elevation myocardial infarction (STEMI) patients, a rapid diagnosis is imperative to reduce total ischaemic time minimizing risk for heart failure, serious arrhythmias, or death. Prehospital context is complex, and the patient delay constitute major part of the pre-hospital phase. LÄS MER

  5. 4. Underwater Worlds : An Ethnography of Waste, Pollution, and Marine Life

    Sammanfattning : In this dissertation, I investigate relations between humans, waste, pollution, and marine life. I introduce the concept of Aquabiopolitics as a means to understand how humans govern life in water in order to enrich human life on land. LÄS MER

  7. 5. Systems Aspects of Increased Swedish Waste Incineration

    Författare :Jenny Sahlin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biological treatment; incineration tax; waste management; waste import; value of households’ time.; waste incineration; district heating; MSW; landfilling ban; recycling;

    Sammanfattning : Abstract Recent bans on landfilling of combustible and organic waste in Sweden have resulted in an increase in alternative waste treatment, especially waste incineration with energy recovery. This thesis elucidates how the current increase in Swedish waste incineration affects and is affected by the two systems to which it belongs: the waste management and the energy systems. LÄS MER
