2. 1. Chemical emissions from building structures : emission sources and their impact on indoor air

   Author : Annika Glader; Ingrid Liljelind; Berndt Stenberg; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; indoor air quality; VOC; building structures; emissions; health effects; moisture damage; PCA; OPLS; inomhusluft; VOC; konstruktioner; emissioner; hälsoeffekter; byggnadsmaterial; fuktskada; PCA; OPLS; Occupational and Environmental Medicine; arbets- och miljömedicin;

   Abstract : Chemical compounds in indoor air can adversely affect our comfort and health. However, in most cases there is only a limited amount of information available that can be used to assess their health risk. Instead the precautionary principle is often applied, i.e. READ MORE

4. 2. An evaluation of regional sustainability by analysing energy and carbon flows – A study of Jämtland, Sweden

   Author : Torbjörn Skytt; Bengt-Gunnar Jonsson; Fredrik Ståhl; Magdalena Svanström; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Regional sustainability; Energy flows; Exergy; Carbon GHG fluxes; Sustainability indicators; carbon dioxide emissions; methane emissions; nature emissions;

   Abstract : Models showing the anthropogenic and natural flows of two sustainability indicators; carbon based GHG and energy (as work energy) have been made for the Swedish region Jämtland. The methodology used was inspired by the study sustainability analysis conducted on the small Danish island Samsø using the above two indicators. READ MORE

5. 3. Nature and the Social Sciences : Examples from the Electricity and Waste Sectors

   Author : Mikael Klintman; Sociologi; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ecology; critical realism; electricity; environment; epistemology; green identity; greening; meta-theory; nature; ontology; social science; public participation; waste; windpower; sociology; Sociologi;

   Abstract : The book has two interrelated objectives. One objective is meta-theoretical and concerns the exploration of theoretical debates connected to issues of studying society and environmental problems; another objective is empirical/analytical, referring to the analysis of "green" public participation in the electricity and waste sectors in Sweden, and partly in the Netherlands as well as the UK.

6. 4. Towards sustainable heavy-duty transportation : Combustion and emissions using renewable fuels in a compression ignition engine

   Author : Maja Novakovic; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RME; HVO; E85; methanol; ethanol; decarbonization; defossilization; heavy-duty; compression-ignition engine; ow temperature combustion; PPC; emissions; PM; particles; aerosol; OA; SOA; DOC;

   Abstract : Transportation should become sustainable and available to everyone. Currently, transportation accounts for approx. one sixth of greenhouse gas (GHG) emissions globally, and heavy-duty trucks are responsible for almost 30% of that. READ MORE

7. 5. Fischer-Tropsch and FAME Fuels as Alternatives for Diesel Engines; an Experimental Study

   Author : Monica Johansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emissions; SME; Fischer-Tropsch; NOx; Combustion; Alternative fuels; Soot; Biodiesel; RME; FAME; GTL; PME;

   Abstract : Research into alternative fuels is necessitated by our heavy reliance on limited oil reserves and increasingly strict emissions legislation. The studies reported in this thesis involved conducting engine tests using alternatives to fossil Diesel fuel in both heavy-duty and light-duty single cylinder engines. READ MORE
