  2. 1. Facts and Interpretations in Environmental Assessments of Products

    Author : Magnus Bengtsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater systems; weighting; learning; decision making; legitimacy; environmental trade-offs; sewage sludge; life cycle assessment LCA ; controversy; environmental evaluation;

    Abstract : Contemporary environmental discourse increasingly emphasises environmental impacts associated with products. In response to this attention, methods for assessing the impacts of products over their life cycles, life cycle assessment (LCA), have been devised. READ MORE

  4. 2. Environmental Assessment of Air-conditioning Systems. Design Considerations for Swedish Conditions

    Author : Katarina Heikkilä; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental assessment; life cycle assessment LCA ; weighting;

    Abstract : There is an increased awareness about global environmental changes, and a need forproducts and systems with the lowest possible impacts on the environment, withouttrade-offs on the original function or quality. The need for air-conditioning andcomfort cooling in commercial buildings has increased and an appropriate design ofthe air-conditioning system is thus important in order to reduce the environmentalimpact related to air-conditioning of buildings.

  5. 3. Valuation of environmental impacts and its use in environmental systems analysis tools

    Author : Sofia Ahlroth; Göran Finnveden; Lars Drake; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; valuation; weighting; ecosystem services; elimate change; impact assessment; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Valuation of environmental impacts in monetary terms is a both difficult and controversial undertaking. However, the need to highlight the value of ecosystem services in policy decisions has become more and more evident in the face of climate change and diminishing biodiversity in the sea and other ecosystems.

  6. 4. Keep it rolling : Straight-line orientation in South African ball-rolling dung beetles

    Author : Lana Khaldy; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ball-rolling dung beetle; Orientation; Heading direction network; Compass; Weighting; Celestial cues; Sun; Polarised light;

    Abstract : Representing a substantial range and variety in morphological and ecological niche, found on all continents of the globe (except for the Antarctic), the ball-rolling dung beetles provide an excellent model in which to study the heading direction network and the factors by which it is influenced. As soon as a ball-rolling dung beetle has located a fresh dung pile to feed on, it immediately starts shaping a piece of dung into a ball, rolling it away from the dung pat in as straight of a trajectory as the terrain allows.

  7. 5. Framework For Structuring Information For Environmental Management Of Industrial Systems

    Author : Raul Carlson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Life cycle assessment LCA ; data format; characterisation; weighting; information structuring; Design for Environment DfE ; indicator; sustainable development; industrial environmental information systems; database;

    Abstract : This thesis addresses information structuring for reducing cost, facilitate understandability, increase relevance and improve quality of environmental information. The research is based in experience, practical results and syntheses from three different but related research and development projects conducted between 1994 and 2004. READ MORE
