  1. 41. Charting the human lung with inhaled nanoparticles : Development of AiDA - a new diagnostic technique for respiratory disease

    Författare :Jonas Jakobsson; NanoLund: Centre for Nanoscience; []
    Nyckelord :Aerosol; lung; lung deposition; respiratory tract; nanoparticles; ultrafine particles; airspace dimension assessment; AiDA; Chronic obstructive pulmonary disease; COPD; lung morphology;

    Sammanfattning : Changes to the smallest structures of the distal lung are often the first sign of severe respiratory disease, but to date methods to detect and quantify these changes are limited. Chronic obstructive pulmonary disease (COPD) is currently estimated to be the third most common cause of death worldwide, but is to a large extent under-diagnosed, especially at early stages.

  3. 42. Modelling optical properties of morphologically complex soot aerosols

    Författare :Franz Kanngiesser; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aerosol; remote sensing; depolarisation; lidar; black carbon; scattering;

    Sammanfattning : Soot containing aerosol has both adverse impacts on the Earth's climate and on human health. Monitoring soot sources, transport pathways and sinks on global scale requires satellite-borne remote sensing techniques. LÄS MER

  4. 43. Towards sustainable heavy-duty transportation : Combustion and emissions using renewable fuels in a compression ignition engine

    Författare :Maja Novakovic; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RME; HVO; E85; methanol; ethanol; decarbonization; defossilization; heavy-duty; compression-ignition engine; ow temperature combustion; PPC; emissions; PM; particles; aerosol; OA; SOA; DOC;

    Sammanfattning : Transportation should become sustainable and available to everyone. Currently, transportation accounts for approx. one sixth of greenhouse gas (GHG) emissions globally, and heavy-duty trucks are responsible for almost 30% of that. LÄS MER

  5. 44. Benzene-char conversion and particle-vapor characterization in biomass gasification

    Författare :Mario Morgalla; Michael Strand; Leteng Lin; Henrik Wiinikka; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass gasification; fluidized bed; particulate matter; aerosol; char; tars; benzene conversion.; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology;

    Sammanfattning : Biomass is increasingly attracting attention as an alternative to fossil fuels. Gasification permits the thermochemical conversion of biomass into a product gas rich in carbon monoxide and hydrogen. The product gas can be further processed to generate heat, electricity, synthesis gas, chemicals, and biofuels. LÄS MER

  7. 45. Internal Dosimetry in Nuclear Fuel Fabrication : Occupational Exposure to Uranium Aerosols

    Författare :Edvin Hansson; Mats Eriksson; Håkan Pettersson; Per Roos; Michael Sandborg; Bastian Breustedt; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Uranium; Aerosol; Internal; Dose; Nuclear;

    Sammanfattning : The production of nuclear fuel can be associated with occupational exposure to ionizing radiation from radioactive decay of uranium. Such exposure must be sufficiently low and radiation doses adequately determined. Radiation doses from internal exposure, i.e. LÄS MER
