2. 1. Environmental Assessment of Emerging Routes to Biomass Based Chemicals The Case of Ethylene

   Author : Christin Liptow; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fermentation; sugarcane; time lags; gasification; biomass based chemicals; wood; land use; life cycle assessment; ethylene; LCA;

   Abstract : The production of bulk chemicals from biomass instead of fossil resources is perceived as one promising option to decrease society's environmental impact. However, though considerable research and development efforts aim at such production, it might take several more years before biomass based bulk chemicals are fully commercialized. READ MORE

4. 2. Responses of boreal forest understory plant communities to climate and forestry

   Author : Ditte Marie Christiansen; Kristoffer Hylander; Johan Ehrlén; Signe Normand; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; boreal forests; bryophytes; climate; climate change; community temperature index; demography; forest management; microclimate; plants; species interactions; species distributions; time-lags; transplant experiment; understory communities; Ecology and Evolution; ekologi och evolution;

   Abstract : A warming climate is altering species distributions and community compositions. To understand and predict changes in species distributions to climate change, we often use species occurrences together with large-scale regional climate data. This can be problematic for several reasons. READ MORE

5. 3. Evaluation of Adapted Passenger Cars for Drivers with Physical Disabilities

   Author : Björn Peters; Statens väg- och transportforskningsinstitut; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Disabled person; Driver; Car; Adaptation; Equipment; Vehicle handling; Simulator; Adaptive cruise control; Driving aptitude; Thesis; 911 Road: Components of the vehicle; 911 Road: Components of the vehicle; 841 Road: Road user behaviour; 841 Road: Road user behaviour; 84 Road: Road users; 84 Road: Road users;

   Abstract : Driving can provide independent and efficient mobility. However, according to the driving license directive (91/439/EEC) are persons with locomotor impairments are only allowed drive if their disabilities can be compensated. Compensation can be realised by vehicle adaptations. READ MORE

It focuses on the reasons for institutional investors' investment actions on the stock market, and in particular the role of financial information about the quoted companies. READ MORE

7. 5. Effects of Watershed Dynamics on Water Reservoir Operation Planning : Considering the Dynamic Effects of Streamflow in Hydropower Operation

   Author : Nicholas Zmijewski; Anders Wörman; Andrea Bottacin-Busolin; Francesca Pianosi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reservoir operation; dispersion processes; wave diffusion; multi-objective operation; water resource management; discharge variability; power spectrum analysis; Byggvetenskap; Civil and Architectural Engineering;

   Abstract : Water reservoirs are used to regulate river discharge for a variety of reasons, such as flood mitigation, water availability for irrigation, municipal consumption and power production purposes. Recent efforts to increase the amount of renewable power production have seen an increase in intermittent climate-variable power production due to wind and solar power production. READ MORE
