  2. 16. Nasal reactions and the school environment : Nasal patency and lavage biomarkers in relation to ventilation, cleaning and some indoor air pollutants

    Author : Robert Wålinder; Uppsala universitet; []
    Keywords : Medical sciences; acoustic rhinometry; enviromnental illness; eosinophil cationic protein ECP ; formaldehyde; lysozyme; mold; nasallavage; nasal obstruction; N02; rhinitis; school; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Abstract : In Sweden, 2 million persons are exposed to the school environment, and there has been reports on insufficient cleaning, and inadequate ventilation. The nasal mucosa is more easy to study than the lower airways, and rhinitis is common and possibly related to asthma. READ MORE

  4. 17. Carbon Fibres and Carbonaceous Fillers in Engineering Thermosets

    Author : Björn Voigt; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; melamine-formaldehyde; carbon black; phenol-formaldehyde; shungite; mechanical and electrical properties; carbon fibres;

    Abstract : In view of the excellent properties of carbon fibres (CF) and the growing demand for multi-functional materials e.g., electrically conductive composites, engineering thermosets with carbon fibres are highly attractive. Similarly, electrically conductive fillers are of great importance. READ MORE

  5. 18. Short-Pulse Laser Spectroscopy for Combustion Diagnostics - Laser-Induced Fluorescence of Polyatomic Molecules and Developments in Measurement and Evaluation

    Author : Thomas Metz; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pulsed lasers; Physics; Fysik; Laser technology; Laserteknik; non-linear spectroscopy; maximum likelihood; curve fitting; data adjustment; statistical inference; formaldehyde; PAH; polycyclic aromatic hydrocarbons; lifetime imaging; two-dimensional; streak camera; LIF; laser-induced fluorescence; Fluorescence lifetimes; time-resolved;

    Abstract : Combustion is the most important source of energy worldwide. A better understanding of it is essential if pollutant emissions are to be reduced and combustion devices be made more efficient. This requires measurement of physical and chemical combustion parameters. READ MORE

  6. 19. Environmental Factors in Relation to Asthma and Respiratory Symptoms among Schoolchildren in Sweden and Korea

    Author : Jeong-Lim Kim; Gunilla Wieslander; Dan Norbäck; Lena Elfman; Nils Åberg; Uppsala universitet; []
    Keywords : Medical sciences; Allergen; allergy; asthma; dampness; diet; environment; formaldehyde; nitrogen dioxide; plasticizer; schoolchildren; ultrafine particles; MEDICIN OCH VÅRD;

    Abstract : This thesis studied environmental factors in relation to asthma and respiratory symptoms among schoolchildren in two countries. In Sweden, 1014 pupils (5-14 year) in 8 schools participated. Wheeze was reported by 7.8%, current asthma by 5. READ MORE

  7. 20. Application of Passive DOAS using Scattered Sunlight for quantification of gas emissions from anthropogenic and volcanic sources

    Author : Claudia Rivera; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nitrogen dioxide; DOAS; gas emission; sulphur dioxide; volcanic; formaldehyde.; scattered sunlight; anthropogenic;

    Abstract : Monitoring of gas emissions from natural and anthropogenic sources is important due to the negative effects of these emissions on human health, atmospheric quality and ecosystems. Concern over air pollution has increased the need to develop measurement techniques suitable for gas flux determination. READ MORE
