  1. 6. Detektion och aktion vid mögelförekomst i vallfoder till hästar

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

    Author : Elvira Bergkvist; [2021]
    Keywords : ekvin astma; grovfoder; hygienisk kvalitet; hösilage; mykotoxiner; svamp;

    Abstract : Mögel kan vara ett vanligt fynd i vallfoder. Detta kan innebära en hälsorisk för hästar då vissa mögelarter kan bilda mykotoxiner. Även mögelarter utan känd förmåga att bilda mykotoxiner kan innebära en hälsorisk för hästarna då de kan bilda sporer som kan inhaleras av hästarna vilket kan leda till ekvin astma. READ MORE

  3. 7. Neural Network Based Model Predictive Control of Turbulent Gas-Solid Corner Flow

    University essay from Uppsala universitet/Signaler och system

    Author : Simon Wredh; [2020]
    Keywords : computational fluid dynamics; machine learning; system identification; control theory; multi-phase flow; gas-solid flow; rans; lagrangian particle tracking; neural network; model predictive control; bio-aerosol;

    Abstract : Over the past decades, attention has been brought to the importance of indoor air quality and the serious threat of bio-aerosol contamination towards human health. A novel idea to transport hazardous particles away from sensitive areas is to automatically control bio-aerosol concentrations, by utilising airflows from ventilation systems. READ MORE

  4. 8. Lung Deposition of Airborne Particles - Resolved in a Single Breath

    University essay from Lunds universitet/Ergonomi och aerosolteknologi

    Author : Amalia Larsson Hurtig; [2020]
    Keywords : Aerosols; Airborne particles; Inhalation; Lung deposition; Respiratory tract deposition; Technology and Engineering;

    Abstract : Exposure to airborne particulate matter has been declared to cause cardiovascular and respiratory disease as well as cancer. By understanding how the aerosol particles deposit in our respiratory tract, we can understand how the exposure to airborne particles affect our health. READ MORE

  5. 9. Carbonaceous aerosols and trace metal deposition in high-latitude snow : a comparative study in Sweden and Alaska

    University essay from SLU/Dept. of Soil and Environment

    Author : Anika Pinzner; [2019]
    Keywords : PM; carbon particles; pXRF; arctic; subarctic; EC OC; LAHM; PSAP; TOT; ICP-MS; filter; contamination; albedo;

    Abstract : This study investigates the advantages and disadvantages of several destructive and non-destructive analytical methods that can be employed to characterize airborne par-ticulate matter (PM) deposited in seasonal snow. To this end, a comparative study was conducted on PM obtained from snowpack surveys in two Arctic/subarctic regions of Northern Sweden and Interior Alaska, USA. READ MORE

  6. 10. Studded tire wear - comparison between British Pendulum and Pin on disc testing

    University essay from KTH/Maskinkonstruktion (Avd.)

    Author : Ryohei Kozuka; [2017]
    Keywords : Studded tire; Concrete road wear; Pin on disc; British Pendulum; Dubbdäck; betongväg; nötning; pinne-på-skiva; Brittisk pendel;

    Abstract : Studded tires are widely used during the winter season in the Nordic countries due to their performance qualities in extreme cold temperatures, however they cause wear on the road surface. This is not only an economic problem but also a health problem due to amount of airborne wear particles that are generated. READ MORE
