1. 6. Biomass in a Sustainable Energy System

   Författare :Pål Börjesson; Miljö- och energisystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kontroll av utsläpp; Miljöteknik; pollution control; Environmental technology; economic valuation; environmental impact; carbon dioxide; Biomass; energy efficiency; Energiforskning; Energy research;

   Sammanfattning : The increased use of biomass for energy is as a key strategy in reducing carbon dioxide (CO2) emission, which represents the largest anthropogenic contribution to the greenhouse effect. In this thesis, aspects of an increase in the utilisation of biomass in the Swedish energy system are treated. LÄS MER

3. 7. Growth versus the Environment - Is There a Trade-off?

   Författare :Per Kågeson; Miljö- och energisystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; emissions reduction; material intensity; pollution control; sustainable development; resource depletion; environment; economic growth; energy; Environmental technology; Miljöteknik; kontroll av utsläpp;

   Sammanfattning : This book shows that the intensity of use of energy and materials in OECD countries is diminishing over time despite falling metal and energy prices. Material demand is sometimes falling in absolute terms, but there are also a few examples of rapid growth. LÄS MER

4. 8. Control of Hybrid Electric Vehicles with Diesel Engines

   Författare :Karin Jonasson; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; robotteknik; Automatiska system; simulation; hybrid vehicle; diesel engines; Automation; control engineering; robotics; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

   Sammanfattning : This thesis is an approach to improve electric hybrid vehicles with respect to fuel consumption and to fulfil the future intended NOX emission regulations. It is based upon the conclusions made in the licentiate thesis Analysing Hybrid Drive System Topologies (Jonasson, 2002). LÄS MER

5. 9. Tourism, Ecosystem Functions, and Human-Environmental Relations

   Författare :Stefan Gössling; Institutionen för tjänstevetenskap; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social geography; Ecology; Zanzibar; world system theory; sustainable tourism; sustainable development; rainforests; human-environmental relations; groundwater; environmental consciousness; ecotourism; ecosystem functions; economic transition; cost-benefit analysis; coastal zone management; coastal communities; climate change; Air-traffic; biodiversity; Environmental technology; pollution control; Ekologi; Zanzibar; Socialgeografi; Miljöteknik; kontroll av utsläpp;

   Sammanfattning : The thesis aims at deconstructing the sustainable tourism paradigm: can tourism be "a global strategy for sustainable development", as the tourist industry claims? And will developing countries in particular profit from tourism development?To most international organizations and institutions (from the World Wide Fund for Nature to The World Bank), tourism, if carefully managed, is a positive, sustainable development tool. However, the research presented in this thesis exposes this view as unrealistically optimistic for at least three reasons: first of all, global environmental change caused by tourism has never been investigated and integrated with the discourse on sustainable tourism development.

7. 10. On the Determination of Reactive Compounds in Aerosols

   Författare :Mårten Spanne; Ergonomi och aerosolteknologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; industrial hygiene; isocyanates; particles; sampling; aerosols; pollution control; Miljöteknik; kontroll av utsläpp;

   Sammanfattning : Many sources of airborne contaminants have always been present in various work environments. With the development of thermosetting plastic systems, the use of reactive chemical compounds was greatly increased and thus also the risk of exposure to reactive and potentially hazardous compounds.
