  1. 1. Refining the particulate matter airway deposition arising from indoor cooking-related biomass combustion for children in the Haramaya district in Ethiopia

    University essay from Lunds universitet/Ergonomi och aerosolteknologi

    Author : Kasper Malmborn; [2023]
    Keywords : Air pollution exposure; charcoal; wood; animal dung; low-income setting epidemiology; Technology and Engineering;

    Abstract : Background: Air pollution, a global issue affecting millions of individuals, is linked to adverse health effects on the respiratory system, but also to e.g., cancer and cardiovascular ailments. In low-income countries, cooking is often conducted by biomass-combustion, causing women and children to be exposed to high levels of indoor air pollution. READ MORE

  3. 2. Microstructure characteristics and tribological behaviour of plasma sprayed ceramic coatings

    University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

    Author : Luigi Fadini; [2023]
    Keywords : Thermal spray; APS; SPS; tribology; wear resistant ceramic coatings;

    Abstract : Surface engineering is increasingly becoming inevitable for meeting the high-performance requirements constantly expected from modern engineering components. Higher demands for combined functionalities, which a base material alone cannot provide, motivate intensive academic studies on various types of coatings, with the ultimate objective of their practical utilisation in industries.

  4. 3. Development and analysis of a commercial hair treatment

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Johanna Johansson; Nina Alian; [2022]
    Keywords : pharmaceutical technology; hair mask; organic; Rapsodine; environmental friendly; cosmetic; hair; Chemistry;

    Abstract : Development and analysis of a commercial hair mask Our degree project has been to develop and analyse a hair mask. We tried out different “recipes” for the hair mask in the lab, and then used different methods to evaluate our recipes to find out which one is the best. READ MORE

  5. 4. Atmospheric Attenuation for Lidar Systems in Adverse Weather Conditions

    University essay from Umeå universitet/Institutionen för fysik

    Author : Johan Viklund; [2021]
    Keywords : Lidar; Lidar equation; Extinction coefficient; Signal attenuation;

    Abstract : In this study, the weather impact on lidar signals has been researched. A lidar system was placed with a target at approximately 90 m and has together with a weather station collected data for about a year before this study. READ MORE

  6. 5. Monte Carlo simulations of Linear Energy Transfer distributions in radiation therapy

    University essay from Uppsala universitet/Högenergifysik

    Author : David Dahlgren; [2021]
    Keywords : Radiotherapy; Particle Physics; Linear Energy Transfer; proton therapy; carbon ion therapy;

    Abstract : In radiotherapy, a quantity asked for by clinics when calculating a treatment plan, along withdose, is linear energy transfer. Linear energy transfer is defined as the absorbed energy intissue per particle track length and has been shown to increase with relative biologicaleffectiveness untill the overkilling effect.
