  1. 16. Fördelar och nackdelar med olika strömaterial ur hästvälfärds- och gödselhanteringsperspektiv

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Jessica Vahlberg; [2016]
    Keywords : häst; hästhållning; kompostering; liggbeteende; luftburna partiklar; luftkvalité; airborne particles; air quality; composting; equine; horse; horse keeping; lying behaviour;

    Abstract : Valet av strömaterial har en betydande påverkan på hästens välfärd då det inverkar på luftkvalitén i stallet, hästens liggbeteende och möjlighet till sysselsättning för hästen. Strömaterialet påverkar också gödselhanteringen gällande lagring, gödselvolym samt komposterbarhet. READ MORE

  3. 17. Size-dependent airborne particle emissions from ship traffic

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

    Author : Fredrik Mattsson; [2016]
    Keywords : Aerosol particle; shipping; emission; health effect; particle number concentration; particle number size distribution; Physics and Astronomy;

    Abstract : Most aerosol particles emitted from shipping affect the climate by counteracting the greenhouse effect. Although, this masks the warming effect of greenhouse gases, aerosol particles also have a negative health effects, and therefore emissions need to be reduced. READ MORE

  4. 18. Development of Wet Electrostatic Precipitator for Generation of Nanoparticle-Protein Solution

    University essay from Lunds universitet/Ergonomi och aerosolteknologi

    Author : Julia Adner; [2015]
    Keywords : WESP; Nanoparticle; bioligical identity; protein solution; Technology and Engineering;

    Abstract : To examine nanoparticle toxicity there is a need to produce defined nanoparticles dispersed in a colloidal suspension. Such a solution could also be interesting for other fields such as nano-medicine. In order to disperse the particles in the liquid there are often surfactant added to the process that alternates the surface of the particles. READ MORE

  5. 19. Aerosol emission from cleaning sprays - design and evaluation of a generation and a characterization system for spray aerosols and a human pre-exposure study

    University essay from Lunds universitet/Ergonomi och aerosolteknologi

    Author : Karin Lovén; [2015]
    Keywords : Aerosol; spray; emission; characterization; dose-response; Technology and Engineering;

    Abstract : In Sweden, the 10th most common occupation is professional cleaning. Cleaning workers are exposed to many risk factors including high physical workload and the development of new-onset asthma and other types of respiratory symptoms. READ MORE

  6. 20. Is there new particle formation in the marine boundary layer of the North Sea?

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Natalia Kelbus; [2014]
    Keywords : Geography; Physical Geography; aerosol particles; new particle formation; nucleation; particle size distribution; NanoMap; Science General; Earth and Environmental Sciences;

    Abstract : The effect of aerosol particles on climate and the human health emphasizes the necessity to focus on the research about aerosol particles. Aerosol particles emitted due to anthropogenic activities increase the scattering and absorption of solar radiation in the atmosphere which leads to an increased cooling of the climate (direct effect).
