2. 11. Risk Estimation of Groundwater Drawdown in Subsidence Sensitive Areas

   Author : Jonas Sundell; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; uncertainty quantification; urban hydrogeology; pore pressure reduction; subsidence; geostatistics; groundwater leakage; soft soil; groundwater drawdown; spatial variability; settlement; probabilistic; risk assessment;

   Abstract : Groundwater drawdown induced ground subsidence is a severe problem in many regions around the world. Leakage of groundwater into a sub-surface construction, resulting in drawdown and subsequent subsidence, can lead to immense damage costs on buildings and installations in urban areas. READ MORE

4. 12. Local or central snow deposits?

   Author : Karin Reinosdotter; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Abstract : Snow handling includes activities such as removing, transporting and dumping the snow, as well as controlling the slipperiness. It is a complex issue that has been widely discussed in the media during the past years. The discussions have been focused mainly on snow deposits and the effect created by de icers. READ MORE

5. 13. Accumulation and Composition of Gully Pot Sediments under Varying Anthropogenic Activities

   Author : Haoyu Wei; Lian Lundy; Maria Viklander; David Butler; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Catch basin; Stormwater; Sediment; Urban runoff; Xenobiotics; Gully pot maintenance; Emerging pollutant; VA-teknik; Urban Water Engineering;

   Abstract : Gully pots (GPs) are an integral urban drainage component, contributing to conveying runoff from urban surfaces and reducing the load of solids and associated contaminants entering downstream piped systems and receiving waters. Over time, the silting-up of GPs impairs their hydraulic performance, increasing the risk of GP blockage-induced flood events and reducing solids retention performance. READ MORE

6. 14. Experimental measurements of water mist systems and implications for modelling in CFD

   Author : Bjarne Husted; Avdelningen för Brandteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technological sciences; fire suppression; CFD; FDS; fire safety engineering; PDA; water mist; PIV;

   Abstract : The use of water mist for fire extinguishment has increased rapidly in recent years. The main reason is the abandonment of halon-based extinguishing systems in favour of environmentally friendlier systems. Furthermore the use of water mist systems has spread from mainly marine applications to also include the protection of buildings. READ MORE

7. 15. Engineered nanomaterials in in vivo and in vitro models

   Author : Laura Abariute; NanoLund: Centre for Nanoscience; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V semiconductor nanowires; Nanoparticle exposure; Mouse exposure; Cell exposure; Nanotoxicology; Nanosafety; Fysicumarkivet A:2018:Abariute;

   Abstract : Nanotechnology and engineered nanomaterials (ENM) empower existing technologies. One of the great examples are III-V semiconductor nanowires (NW), which have a broad application range. The occupational safety and hazard organizations draw attention to ENM, as their physical and chemical characteristics differ from the ones of bulk materials. READ MORE
