  1. 1. DIFFERENCES ON THE IMPACTS AND ORIGINS OF POLLEN IN FOUR MAJOR SWEDISH CITIES BETWEEN 2014 AND 2019

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Jean-Patrick Ridet-Lagorce; [2024-02-12]
    Keywords : Pollen; Allergy; Antihistaminic; Airborne transport; Geographical origins;

    Abstract : Allergies are widespread in the world and coming from various sources, one of the causes being airborne allergens and especially, pollen. The negative impact of pollen is enhanced by pollution and climate change which are some of the biggest issue humankind is facing today. READ MORE

  3. 2. Seasonal Variability of Ice Nucleating Particles (INP) in Southern Sweden

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Tamina Kabir; [2023-03-08]
    Keywords : ;

    Abstract : Cloud ice crystals are formed by ice-nucleating particles (INPs). The micro-physical properties of clouds, precipitation formation and the life cycle of clouds are strongly influenced by the presence or absence of ice. Therefore knowledge of atmospheric INP concentrations is crucial to improve weather forecasting and climate projections. READ MORE

  4. 3. Can ancient pathogens emerging from glaciers and permafrost reach Europe by aerosolization?

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Anna Bruhn; [2023]
    Keywords : Ancient pathogens; Greenland; Aerosolized pathogens; Aerosol transport; Earth and Environmental Sciences;

    Abstract : Glaciers and permafrost capture bacteria and viruses when they form, which can be suspended for millennia. This includes long since extinct pathogens which are functionally novel. As polar regions get warmer these pathogens will emerge and spread through the local ecosystem, potentially altering it. READ MORE

  5. 4. Evaluation of a stochastic model of coherent turbulent structures for atmospheric particle deposition applications

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Andreas Eriksson; [2022]
    Keywords : atmospheric dispersion; particle deposition; k-epsilon; RANS; lagrangian particle model; stochastic particle model; OpenFOAM; SIMPLE algorithm; ABL; atmospheric boundary layer; neutral boundary layer; coherent turbulent structures;

    Abstract : In this thesis, we have evaluated a stochastic Lagrangian model for computing particle deposition rates with prospects to use for atmospheric deposition applications.  The model is one-dimensional and models the particle dynamics in the boundary layers near walls and obstacles by simulating the coherent turbulent structures and Brownian motion governing the wall-normal transport.

  6. 5. Inhibited surface-thiols in Geobacter sulfurreducens : Mercury uptake and methylation rates

    University essay from Umeå universitet/Kemiska institutionen

    Author : Andreas Granström; [2021]
    Keywords : ;

    Abstract : Due to daily human (anthropogenic) industrial activity, a lot of elemental mercury (Hg0) has been released to the atmosphere. The mercury can then spread globally, since mercury has the ability to remain atmospheric for up to a year. When mercury deposits, it can end up in anaerobic environments such as sediments and soil.
