  3. 2. Flow-oriented studies for environmental management by local authorities : experiences from a regional substance flow analysis

    Författare :Annica Lindqvist-Östblom; Linköpings universitet; []
    Nyckelord :flow-oriented studies; material flow analysis; substance flow analysis; interpretation; local authorities; regional authorities; environmental management; cadmium; sewage;

    Sammanfattning : This thesis focuses on the issue of how to perform flow-oriented studies in order to become more useful for and adapted to local/regional authorities. Compared to traditional environmental monitoring and measurement of the state of the environment, flow-oriented studies are an attempt to broaden the approach to environmental concerns. LÄS MER

  4. 3. The role of wastewater in surveillance and emergence of antibiotic resistant bacteria

    Författare :Marion Hutinel; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; Bacteriology; Antibiotic resistance; Surveillance; Horizontal gene transfer; HGT; Conjugation; Plasmids; Epidemiology; CPE; E. coli; Carbapenamase; Linezolid; Colistin; Selection; sul4; OXA-48; gar; NDM; mcr; wastewater; sewage; sewer;

    Sammanfattning : As antibiotic resistance spreads among bacterial pathogens, it reduces treatment options and increases treatment failures of infectious diseases. Strategies employed to reduce this spread or adapt to its consequences need to be based on reliable surveillance data which is lacking in many countries, often due to limited resources. LÄS MER

  5. 4. Samnyttjad mark och urbana allmänningar : En fallstudie av skyfallsanpassning i Malmö och Köpenhamn

    Författare :Per Larsson; Katarina Nylund; Peter Parker; Richard Ek; Malmö universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Urban land use; urban commons; cloudburst; sewage system; flooding; Malmö; Copenhagen; Samnyttjande; allmänning; urban allmänning; skyfall; dagvatten; LOD; stadsutveckling; markanvändning; Malmö; Köpenhamn; Urban studies; Urbana studier;

    Sammanfattning : I avhandlingen analyseras möjligheter och hinder för samnyttjande av mark utifrån en fallstudie av skyfallsanpassning i Malmö och Köpenhamn. Som bakgrund står de klimatutmaningar i form av ökad framtida nederbörd och risk för översvämningar som städerna ställs inför, tillsammans med en tilltagande konkurrens om marken från allt fler behov.

  7. 5. Reducing water damage by using a holistic approach to costs, occurrence and solutions in buildings

    Författare :Christian Mattsson; Avdelningen för Installations- och klimatiseringslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water damage; building defects; Tap water; Costs; Sewage; Heating; Leakage; Vattenskador: byggnader; byggnadsdefekt; kostnader; avlopp; värmesystem; läckage; tappvatten;

    Sammanfattning : A large amount of water damage cases and resources are annually reported and spent on water damage in Sweden from cases occurring in buildings from building services such as tap water-, sewage, heating systems, household appliances such as refrigerators, freezers and dishwashers and inadequate waterproof membranes in wet rooms. These water damage cases in buildings cause several problems in the built environment regarding economic, environmental, and social aspects of sustainability such as unhealthy indoor environments due to higher levels of moisture, mold growth, and redundant usage of building materials and resources in reparations and renovations of water damaged constructions, immense amounts of monetary resources spent annually by both residents, building owners and insurance companies to restore the buildings to their designed purpose.
