  2. 21. Dynamics of Energy Systems - Methods of analysing technology change

    Author : Lena Neij; Internationella miljöinstitutet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy research; evaluation; market transformation; PV modules; wind power; experience curves; air-distribution; lighting; vintage models; sustainable energy; renewable energy; energy efficiency; Energy; energy system; Energiforskning; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Abstract : Technology change will have a central role in achieving a sustainable energy system. This calls for methods of analysing the dynamics of energy systems in view of technology change and policy instruments for effecting and accelerating technology change. In this thesis, such methods have been developed, applied, and assessed. READ MORE

  4. 22. Sampling and analysis of polynuclear aromatic hydrocarbons with special reference to automobile exhausts

    Author : Ulf Stenberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : A literature survey concerning the progress in sampling of polynu clear aromatic hydrocarbons, PAH, from automobile exhausts is pre seated.

  5. 23. Determination of OPAHs and PAHs in Particulate Matter from Ambient Air and Engine Emissions : Multidimensional Chromatography

    Author : Trifa Mohammad Ahmed; Roger Westerholm; Peter Haglund; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

    Abstract : Particulate matter (PM) is an air pollutant that seriously impacts human health. Epidemiological studies have shown associations between human exposure to urban air PM and lung cancer, respiratory and cardiovascular diseases. READ MORE

  6. 24. Breathe without pain : Clinical and experimental studies in patients and volunteers with special reference to ventilatory regilation

    Author : Anders Johnson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The major aims were, first, to study the advantages and disadvantages of intrathecal analgesia with bupivacaine and morphine with special reference to ventilation and pain relief and, second, to develop a method for studies of the ventilatory response to carbon dioxide and hypoxaemia in volunteers and in patients with varying degrees of ventilation-perfusion ratios.341 elderly patients undergoing major hip surgery perfonned under intrathecal analgesia or general anaesthesia and 31 young and healthy volunteers participated in this work.
