    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Outdoor thermal comfort; Microclimate; Thermal perception; Urbanites; Informal settlements; Informal urban fabric; Warm humid climates; Dar es Salaam; Physiological Equivalent temperature PET ; New Standard Effective Temperature SET* ; Universal Thermal Climate Index UTCI ;

    Sammanfattning : In the informal settlements of warm humid climates, where the majority of urbanites spend most of their time outdoors, a conducive thermal environment is crucial for their social and economic well-being. The overall aim of this thesis is to increase knowledge and understanding of outdoor thermal comfort in informal settlements in the warm and humid climate of Dar es Salaam, Tanzania. LÄS MER

  3. 22. Impacts of urbanisation on birds : Disentangling the effects of multiple pollutants on avian behaviour and physiology

    Författare :Ann-Kathrin Ziegler; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; artificial light at night; ALAN; antioxidants; great tit; light pollution; LPS; multi-stressor; noise pollution; tropospheric ozone; urbanisation; zebra finch;

    Sammanfattning : Anthropogenic pollution is a pervasive feature of urbanisation, reaching into ecosystems worldwide and posing novel challenges to wildlife. Not surprisingly, differences in behaviour, and physiology, have been found between urban and rural populations. LÄS MER

  4. 23. Optimization of Snow Removal in Cities

    Författare :Roghayeh Hajizadeh; Kaj Holmberg; Elina Rönnberg; Henrik Andersson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Removing snow in a city is an unavoidable task in Nordic countries like Sweden. A number of streets in an area need to be cleared of snow by a limited number of vehicles and the tours for the vehicles must be planned in order to minimize the time and/or cost. LÄS MER

  5. 24. The nature of human habitats : revealing outdoor recreation preferences through landscape utilization

    Författare :Carl Lehto; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : A reduction of accessible green space has deteriorated peoples’ opportunities for recreation. To be able to assess landscapes’ potential for recreation, indices and frameworks have been developed. These have mostly relied on expert knowledge rather than analyses of empirical data. LÄS MER

  7. 25. Predation and shorebirds: predation management, habitat effects and public opinions

    Författare :Daniel Isaksson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Conservation; waders; predation; coastal pastures; redshank; lapwing; attitudes; human dimensions;

    Sammanfattning : Many shorebird populations are rapidly declining and a high nest predation rate is one of the threats facing these populations. Thus, factors that affect predation and how to manage it in an effective way are receiving increased attention. LÄS MER
