  2. 1. Mechanical modelling of blade forming and drainage of flocculated suspensions

    Author : Claes Holmqvist; Anders Dahlkild; Douglas Bousfield; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; blade forming; pressure distribution; interaction; suction; drainage; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

    Abstract : A method has been developed for flexible modelling of multi-component twin-wire blade formers. Features such as suction devices, loadable blades, curved blades, and partial contact between the blades and the forming fabrics are easily incorporated. READ MORE

  4. 2. Green Urban Drainage Infrastructure : Hydrology and Modelling of Grass Swales

    Author : Hendrik Rujner; Maria Viklander; Günther Leonhardt; Jiri Marsalek; Barraud Sylvie; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

    Abstract : The management of urban runoff has evolved along with the advancement of understanding of runoff environmental impacts. Besides the impacts on water quality in the receiving waters, the impacts on the urban hydrologic regime include reduced infiltration by the sealing of pervious land, reduced evapotranspiration by removal of vegetation, and the resulting increase of stormwater runoff peaks and volumes causing flooding, and ultimately degradation of receiving waters.

  6. 4. Urban drainage and climate change : impact assessment

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

    Abstract : 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.

  7. 5. Surgical treatment strategies of chronic subdural hematoma

    Author : Andreas Bartley; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chronic subdural hematoma; irrigation; recurrence; temperature; drainage time; drainage duration; surgery;

    Abstract : Background: A subdural collection of old blood is called a chronic subdural hematoma (cSDH). A cSDH of sufficient volume becomes symptomatic and neurosurgical evacuation is then necessary. The recurrence rate (5-21%) after surgery is high and evidence-based guidelines regarding the optimal treatment to diminish recurrence is lacking. READ MORE
