  1. 1. Water and Heat Transport in Road Structures Development of Mechanistic Models

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Klas Hansson; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Water flow; Heat flow; Unsaturated flow; Freeze-thaw; Numerical models; Uncertainty analysis; Sensitivity analysis; Roads; Overland flow; Flow patterns; TDR; Water content reflectometer; Calibration; Fractures; Hydrologi; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Hydrology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Hydrologi;

    Abstract : The coupled transport of water and heat, involving freezing and thawing, in the road structure and its immediate environment is important to consider for optimal design and maintenance of roads and when assessing solute transport, of e.g. de-icing salt, from roads. READ MORE

  2. 2. Urban, pluvial flooding : Blue-green infrastructure as a strategy for resilience

    University dissertation from Faculty of Engineering (LTH), Lund University

    Author : Johanna Sörensen; Lunds universitet.; Lund University.; [2018-08-06]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urbanhydrologi; pluviala översvämningar; resiliens; blå-grön infrastruktur; socio-teknisk förändring; Urban hydrology; Pluvial flooding; Resilience; Blue-green infrastructure; socio-technical transition;

    Abstract : This thesis investigates urban, pluvial flooding and if blue-green infrastructure, for handling of stormwater in urban green spaces, can be used as a strategy for resilient flood risk management. Spatial analyses of flood claims from insurance companies and the water utility company of Malmö are used to better understand the mechanisms and characteristics of pluvial flooding and how blue-green infrastructure impacts flood risk.

  3. 3. Nitrifyers in constructed wetlands treating landfill leachates

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Carina Sundberg; Linköpings universitet.; Linköpings universitet.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN;

    Abstract : Landfill leachate is produced many years after a landfill site closes. Hence, treatment by “natural methods”, as e.g. constructed wetlands, with low management requirements is attractive. READ MORE

  4. 4. On-farm agrohydrological analysis of the Sahelian yield crisis : rainfall partitioning, soil nutrients and water use efficiency of pearl millet

    University dissertation from Stockholm : Stockholms universitet

    Author : Johan Rockström; Stockholms universitet.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; NATURVETENSKAP; naturresurshushållning; Natural Resources Management;

    Abstract : Sub-Saharan Africa is presently experiencing a steadily aggravated food security crisis. This crisis is a result of a rapidly growing population combined with insignificant yield increases of the major cereal crops maize, millet and sorghum, during the last decades. READ MORE

  5. 5. Antibiotic Resistance in Wastewater Methicillin-resistant Staphylococcus aureus (MRSA)and antibiotic resistance genes

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Stefan Börjesson; Linköpings universitet.; Linköpings universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MRSA; SCCmec; spa typing; Staphylococcus aureus; methicillin; B-lactam; aminoglycoside; tetracycline; antibiotic; wastewater; wastewater treatment plant; NATURAL SCIENCES Biology Organism biology Microbiology; NATURVETENSKAP Biologi Organismbiologi Mikrobiologi;

    Abstract : A large part of the antibiotics consumed ends up in wastewater, and in the wastewater the antibiotics may exert selective pressure for or maintain resistance among microorganisms. Antibiotic resistant bacteria and genes encoding antibiotic resistance are commonly detected in wastewater, often at higher rates and concentrations compared to surface water. READ MORE
