  1. 1. 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.

  3. 2. The Underground as a Storage Facility. Modelling of Nuclear Waste Repositories and Aquifer Thermal Energy Stores

    Författare :Thomas Probert; Matematisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; exponential decay; modelling; fractured rock; classical mechanics; quantum mechanics; Mathematical and general theoretical physics; relativity; statistical physics; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; relativitet; kvantmekanik; gravitation; statistisk fysik; termodynamik; Environmental technology; pollution control; kontroll av utsläpp; Miljöteknik; conformal flow; heat as a tracer; KBS-3; stress field; temperature field; analytical solution; salt buoyancy; groundwater flow; nuclear waste repository; aquifer thermal energy storage; Fysicumarkivet A:1998:Probert;

    Sammanfattning : The underground is a vast region, which is, too a large extent, unused by man. It has a large potential as a storage facility due to its vastness and availability. This thesis, which consists of eleven papers and reports, deals with nuclear waste repositories in solid rock and with aquifer thermal energy storage systems. LÄS MER

  4. 3. Energy Use, Efficiency Gains and Emission Abatement in Transitional Industrialised Economies: Poland and the Baltic States

    Författare :Jürgen Salay; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; implementation; sustainable energy; renewable energy; electricity production; power industry; Baltic states; Poland; transition; sulphur dioxide; air pollution; energy efficiency; Energy; energy use; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; Energy research; Energiforskning;

    Sammanfattning : This thesis is a study of how energy use and air pollution in Poland, Estonia, Latvia and Lithuania have been affected by the economic transition after 1989. It consists of six articles, which examine three different aspects of these changes. LÄS MER

  5. 4. Renewable Energy in Energy-Efficient, Low-Pollution Systems

    Författare :Bengt Johansson; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen; ethanol; methanol; rape methyl ester; biomass; renewable energy; cogeneration; energy efficiency; scenarios; air pollution; carbon dioxide; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Sammanfattning : Energy use accounts for the dominating fraction of total sulphur dioxide (SO2), nitrogen oxide (NOx), volatile organic compounds (VOCs) and carbon dioxide (CO2) emissions. In this thesis, different strategies for reducing these emissions are evaluated, using a bottom-up approach. The thesis is divided in two parts. LÄS MER

  7. 5. Industrial Management Models with Emphasis on Construction Waste

    Författare :Jan Stenis; Byggproduktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Commercial and industrial economics; ekonomisk politik; ekonomiska system; ekonomisk teori; Management of enterprises; Industriell ekonomi; Technological sciences; management; Företagsledning; Building construction; Teknik; Byggnadsteknik; Ekologi; Ecology; sustainable development; Polluter-Pays Principle; contribution margin analysis; cost benefit analysis; construction waste; Economic models; integrated industrial waste management; kontroll av utsläpp; Miljöteknik; Environmental technology; pollution control; Economics; Environmental Law; Morallära; Moral science; Miljömedicin; Environmental health; Miljörätt; economic theory; econometrics; economic systems; Nationalekonomi; ekonometri; economic policy;

    Sammanfattning : Increased attention is nowadays devoted to waste management. The objective of this work is to analyse how commonly known business economic models and methods, as well as the Polluter-Pays Principle, can be applied to waste management in general and to waste fractionation in particular, so as to facilitate environmental optimisation of industrial and construction waste fractionation.
