  1. 31. Study of spatial and temporal variation of atmospheric optical parameters and their relation with PM 2.5 concentration over Europe using GIS technologies

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Panagiotis Symeonidis; [2017]
    Keywords : aerosols; air quality; satellite remote sensing; GIS; geography; Geographical Information Systems; particulate matter; Aerosol Optical Depth; MODIS; Earth and Environmental Sciences;

    Abstract : The purpose of this study was to examine the use of remote sensing aerosol data as an estimator of ground level fine particulate matter concentration (PM 2.5). In order to examine this possible relation, daily MODIS Aerosol Optical Depth (AOD) data were used, collected for an entire year. READ MORE

  3. 32. Development of a high flow aerosol sampling device

    University essay from Lunds universitet/Innovation

    Author : Saman Souzani; Hamza Licina; [2017]
    Keywords : Technology and Engineering;

    Abstract : Small biological airborne particles (aerosols) reside in the atmosphere and can influence human health, the climate and the environment. Whereas aerosol sampling technology is well-known, there is currently no satisfactory high-volume flow impinger for health and atmospheric monitoring applications. READ MORE

  4. 33. Experimental and theoretical studies of water droplet surfaces in the presence of glycerol

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Nygren Anton; [2017]
    Keywords : glycerol; water surface; BESSY II; MD; GROMACS; PES; XPS; glycerol; vattenytor; BESSY II; MD; GROMACS; PES; XPS;

    Abstract : Water aerosols affect the climate because they have an impact on the radiation balance and cloud formation. Water is present in all forms in the atmosphere (water, ice and steam), for example as rain and hail. Water aerosols play an important role in many biological and chemical processes in the atmosphere. READ MORE

  5. 34. Investigation of scattering of soot with a three-wavelength integrating nephelometer

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Maj Blomdell; [2017]
    Keywords : Soot particles; aerosols; combustion; integrating nephelometer; scattering; light; LED s; Physics and Astronomy;

    Abstract : Soot particles are one of the major contributors to climate change and global warming, mostly due to their absorbing effect. It is of great interest to gain better knowledge about soot particles optical properties, since there are great uncertainty how they affect the atmosphere. READ MORE

  6. 35. Kennelhosta hos hund : etiologi, spridning och prevention

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Evelina Andersson; [2017]
    Keywords : kennelhosta; patogener; Canine parainfluenzavirus-2; Bordetella bronchiseptica; Canine respiratory coronavirus; utbrott; vaccin;

    Abstract : Kennelhosta är en respiratorisk sjukdom med hög prevalens hos hund, med en symtombild som innefattar torrhosta, näsflöde och dyspné. Sjukdomen utbryter ofta i miljöer där hundar med olika bakgrunder introduceras och när individer vistas nära inpå varandra. READ MORE
