  2. 1. Exploring patterns of empirical networks

    Author : Luis E C Rocha; Petter Holme; Kimmo Kaski; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; complex systems; complex networks; network analysis; empirical networks; air transportation; consumer complaints; information technology; sexual contacts; epidemics; vaccination; Statistical physics; Statistisk fysik; Computational physics; Beräkningsfysik; Technology and social change; Teknik och social förändring; Epidemiology; Epidemiologi; Information technology; Informationsteknik; fysik; Physics; Statistics; statistik; Epidemiology; epidemiologi; Economics; nationalekonomi;

    Abstract : We are constantly struggling to understand how nature works, trying to identify recurrent events and looking for analogies and relations between objects or individuals. Knowing patterns of behavior is powerful and fundamental for survival of any species. READ MORE

  4. 2. On the Formation and Physical Behaviour of Exhaled Particles

    Author : Helene Holmgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; breath hold; size distribution; deposition; relative humidity; tidal breathing; exhaled particles; airway closure; film droplet;

    Abstract : Aerosol particles are generated in human airways and leave the body with exhaled air. The particles originate from the respiratory tract and contain non-volatile compoundsthat potentially may be used as biomarkers for various medical conditions. To utilise any information provided by the particles, they must be characterised. READ MORE

  5. 3. Health-related aerosol particle studies, respiratory tract deposition and indoor source identification

    Author : Jakob Löndahl; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aerosol particle; health; ultrafine particles; nanoparticle; deposition; respiratory tract; Fysicumarkivet A:000;

    Abstract : Aerosol particles have, since Classical Antiquity, been linked to adverse effects on human health. It is estimated that the particles in urban air pollution causes 100 000 deaths in Europe each year, whereof 5 000 in Sweden. READ MORE

  6. 4. Social Construction of Technical Aids - Personal Meaning and Interactional Effects of Disability and Assistive Devices in Everyday Life

    Author : Oskar Krantz; Institutionen för hälsovetenskaper; []

    Abstract : Early detection is vital to successfully treating breast cancer, and mammography screening is the most efficient and wide-spread method to reach this goal. Imaging low-contrast targets, while minimizing the radiation exposure to a large population is, however, a major challenge. READ MORE
