1. 1. Bioaerosols and their importance for low-level Arctic clouds

   Författare :Gabriel Pereira Freitas; Paul Zieger; Radovan Krejci; Kevin J. Noone; Claudia Mohr; Martin Gallagher; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bioaerosols; Aerosols; Clouds; Arctic; Cloud Condensation Nuclei; Ice Nucleating Particles; Sea Spray Aerosol; Environmental Sciences; miljövetenskap;

   Sammanfattning : Bioaerosols are microorganisms or functional parts of them or other biological matter suspended in air. Examples are bacteria, viruses, pollen, spores, or smaller plant debris. In the atmosphere, bioaerosols can play various functional roles, such as facilitating the spread of genetic material. LÄS MER

3. 2. An electrostatic sampling device for point-of-care detection of bioaerosols

   Författare :Laila Ladhani; Wouter van der Wijngaart; Jorma Keskinen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrostatic sampling; bioaerosols; point-of-care; breath sampling; electrostatic precipitation; microfluidic collection; corona discharge; air sampling; non-invasive diagnostics; exhaled breath analysis; on-site detection; aerosol sampling; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Bioaerosols are not only a significant factor of air quality but contribute greatly to the spread of infectious diseases, specifically through expired pathogen-laden aerosols. Clear examples of airborne transmission include: the recent influenza pandemic of 2009, the ongoing tuberculosis epidemic, and yearly norovirus out- breaks, which affect millions of people worldwide and pose serious threats to public healthcare systems.

4. 3. Transmission of Infectious Bioaerosols : Sources, transport and prevention strategies for airborne viruses and bacteria

   Författare :Malin Alsved; NanoLund: Centre for Nanoscience; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bioaerosol; infectious disease; Norovirus; Airborne bacteria; aerosols;

   Sammanfattning : Infectious diseases that can be transmitted via air often spread rapidly, sometimes causing large epidemic and pandemic outbreaks. As an increasing number of people live in crowded urban environments, and with frequent and long-distance traveling across the world, infectious diseases can spread even faster. LÄS MER

5. 4. Microorganisms in the atmosphere

   Författare :Camilla Fahlgren; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mikrobiologi; Microbiology;

   Sammanfattning : Bacteria are present everywhere around us; in water, soil, food, on our skin, and in the air we breathe, mainly as parts of aerosols (i.e. minute air-suspended particles). Aerosols are mainly composed of sea salt, dust, sulphates and soot but some also contain bacteria, virus, pollen, plant debris and organic matter (i. LÄS MER

7. 5. Tracking the fate of biocontrol microorganisms in the environment using intrinsic SCAR markers

   Författare :Anna-Ida Johnsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Biocontrol microorganisms can be used as an alternative to conventional chemical pesticides to control plant diseases. This thesis investigated the fate and behaviour of three microbial model control agents with effect against fungal pathogens in cropping systems, and the spread of one of the model strains in bioaerosols.
