  1. 16. Emissioner av nanotrådar från epitaxisubstrat

    Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologi

    Författare :Camilla Abrahamsson; [2021]
    Nyckelord :Nanosäkerhet; epitaxi; arbetsplatsrisk; aerosol; hälsorisk; Technology and Engineering;

    Sammanfattning : Morfologiska likheter med asbest tillsammans med toxikologiska studier i celler och försöksdjur har väckt oro för de potentiella hälsoriskerna om nanotrådar kan bli luftburna och inandas vid hantering. Nanotrådar växta på substrat genom epitaxi kan riskera att skadas under hantering vid förberedelse för analys i mikroskop och detta examensarbete ämnar undersöka huruvida nanotrådar eller fragment av dessa kan lossna från substratet och bli luftburna då detta händer.

  3. 17. Adhesive mixtures for dry powder inhalation

    Magister-uppsats, Uppsala universitet/Institutionen för farmaceutisk biovetenskap

    Författare :Louise Lagercrantz Forss; [2021]
    Nyckelord :Adhesive mixtures; dry powder inhaler; excipients; pulmonary route; powder mixing;

    Sammanfattning : When it comes to dry powder inhalation (DPI), adhesive mixtures are the most widely used formulation type. Various techniques have been developed to generate inhaled drug particles and improve the delivery efficiency of DPI formulations. LÄS MER

  4. 18. The Aerosol-Chase Project. A continental Lagrangian experiment.

    Master-uppsats, Lunds universitet/Kärnfysik

    Författare :Adrian Reyes Martin; [2021]
    Nyckelord :Science General; Earth and Environmental Sciences; Technology and Engineering; Physics and Astronomy;

    Sammanfattning : Determining how aerosol particle number size distributions evolve during long range transport and how aerosol sources contribute to the aerosol population is one of the greatest conundrums in aerosol science. Current monitoring of particle size distribution is done in fixed stations that provide limited information about the reasons why size distribution changes with time. LÄS MER

  5. 19. Development of methods for detection of radioactive aerosols of special importance for the ESS facility

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Martin Carlström; [2021]
    Nyckelord :alpha spectrometry; radioactive aerosols; spectrum simulation;

    Sammanfattning : With the construction of the European Spallation Source (ESS) steadily approaching the operational phase, an environmental monitoring program will soon be implemented with the purpose of monitoring emissions. With regard to radiation safety, it is highly important to monitor alpha emitting radionuclides in aerosol form. LÄS MER

  7. 20. COVID-19 in cats : prevalence of antibodies in cats in Sweden, concern among owners and development of COVID-19 SIA as the analytical method

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical Sciences

    Författare :Jennifer Högberg Jeborn; [2021]
    Nyckelord :COVID-19; SARS-CoV-2; cats; antibodies; seroprevalence; SIA;

    Sammanfattning : COVID-19 is a disease which has had great impact on the world in 2020. It has infected millions of people during the year, and been confirmed in animals such as cats, dogs and minks. The receptor ACE2 which is the target for the virus SARS-CoV-2 to use for attachment to the cell, is very similar between cats and humans. LÄS MER
