1. 31. Generation of urban runoff : Seasonal and climate change perspective

   Författare :Shahab Moghadas; Claes Hernebring; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Sammanfattning : Runoff generation in cold regions is characterized by snowmelt contributions to runoff during the periods of thawing and changing runoff patterns due to frozen ground. This thesis project aimed at addressing these challenges by advancing the procedures for winter urban runoff computations and the assessment of control measures during the winter/spring period, when the snowmelt and frozen soils dominantly impact runoff generation in the current and future climates.

3. 32. Hydrogeological modeling to improve remediation strategies for a drinking water aquifer contaminated by an aqueous phase liquid

   Författare :Martin Bergvall; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In many communities, groundwater is an important source of drinking water. Groundwater aquifers are, however, vulnerable to the widespread and increasing problem of contamination from anthropogenic sources. Once in the groundwater, contaminants are likely to remain there for a long time as the attenuation rate is slow. LÄS MER

4. 33. Energy Efficiency in Shopping Malls : Some Aspects Based on a Case Study

   Författare :Sofia Stensson; Jan-Olof Dalenbäck; Per Fahlén; Monica Axell; Jeffrey Spitler; Sweden Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shopping mall; energy use; energy efficiency; HVAC system; load patterns; case study; regulatory requirements; building code; and energy declarations;

   Sammanfattning : The building sector accounts for approximately 40 percent of our energy use. To reach existing environmental targets energy use will have to be reduced in all building types. At the European level, the main legislative instrument for improving the energy efficiency of the building stock is the Energy Performance of Buildings Directive (EPBD). LÄS MER

5. 34. Allergen-induced late airways reaction in the pig : influence of endogenous and exogenous glucocorticoids

   Författare :Cecilia Fornhem; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Ascaris suum; bronchial circulation; bronchial provocation test; budesonidecortisol; leukotrienes; eosinophil peroxidase; eosinophils; histamine; immunohistochemistry; metyrapone; minipig; myeloperoxidase; neutrophils; pig.;

   Sammanfattning : A novel model for studies of the allergen-induced late reaction in the lower airways was developed in the pig. The influence on late bronchial obstruction and granulocyte function of endogenous cortisol levels and treatment with the glucocorticoid budesonide (BUD) was evaluated. LÄS MER

7. 35. Urban drainage and climate change : impact assessment

   Författare :Karolina Berggren; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Sammanfattning : According to the Intergovernmental Panel on Climate Change (IPCC, 2007), the global mean temperature has increased by 0,7 °C during the last 100 years and, as a consequence, the hydrological cycle has intensified with, for example, more intense rainfall events. As urban drainage systems have been developed over a long period of time and design criteria are based upon climatic characteristics, these changes will affect the systems and the city accordingly.
