  2. 6. Indoor environment and air quality in hospital units : Symptoms and signs

    Author : Klas Nordström; Uppsala universitet; []
    Keywords : Medical sciences; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Abstract : Indoor environment may influence the occurrence of symptoms such as eye, skin and upper airway irritation, headache and fatigue. The aim of the dissertation was to study relations between subjective indoor air quality, such symptoms, clinical signs from the nose and the eyes and the physical indoor environment, in particular the effect of dampness, type of building, and air humidification.

  4. 7. Evaporative Cycles - in Theori and in Practise

    Author : Per M Rosén; Kraftverksteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motors and propulsion systems; Trigeneration; Combustion Engines; Gas Turbines; CHAT; HAM; HAT; Evaporative Cycles; EvGT; Motorer; framdrivningssystem; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik;

    Abstract : The thesis is based on applied research, rather closed to industrial development. The developed simulation model, for pre-design of evaporative gas turbine cycles, has been validated in a 600 kW pilot plant and in rebuilt turbo-charged diesel engines. READ MORE

  5. 8. Advanced power cycles with mixture as the working fluid

    Author : Maria Jonsson; KTH; []
    Keywords : power cycle; mixture working fluid; Kalina cycle; ammonia-water mixture; reciprocating internal combustion engine; bottoming cycle; gas turbine; evaporative gas turbine; air-water mixture; exergy;

    Abstract : The world demand for electrical power increasescontinuously, requiring efficient and low-cost methods forpower generation. This thesis investigates two advanced powercycles with mixtures as the working fluid: the Kalina cycle,alternatively called the ammonia-water cycle, and theevaporative gas turbine cycle. READ MORE

  6. 9. Modern inhalation agents and effects of anaesthesia equipment during low-flow anaesthesia

    Author : Anders Johansson; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anestesiologi; intensive care; intensivvård; Anaesthesiology; humidity and temperature; heat and moisture exchanger; isoflurane; desflurane; sevoflurane; anaesthetics volatile; carbon dioxide absorber; Low-flow; re-breathing circle circuit;

    Abstract : Volatile agents are economically and ecologically acceptable only when administered via low-flow systems. However, sevoflurane degrades during low-flow anaesthesia to compound A, and a high carbon dioxide absorber temperature increases this degradation. READ MORE

  7. 10. Advanced Gas Turbine Cycles with Water-Air Mixtures as Working Fluid

    Author : Niklas Ågren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas turbine cycles; HAT cycles; evaporative cycles; power generation;

    Abstract : Since the early 80's, the worldwide utilization of gas turbines for thermal power generation has increased rapidly. They have less pollution than any other major combustion energy converters. READ MORE
