  1. 6. Water quality improvement of highway runoff by the filter material D-Rainclean : A five-month field trial

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :William Gulding; [2023]
    Nyckelord :Adsorption; D-Rainclean; metal removal; Reactive filter; stormwater treatment;

    Sammanfattning : Highway runoff and its pollutants are of growing concern. These pollutants require treatment as their concentration often are increased. A common removal method is the use of sedimentation ponds that removes particulates through gravity. LÄS MER

  3. 7. A VVER1000 primary side model in Apros

    Master-uppsats, KTH/Fysik

    Författare :Karl-Edvin Strand; [2023]
    Nyckelord :Apros; VVER1000; PWR; Modelling; HPIS; Boron acid; Apros; VVER1000; PWR; Modellering; HPIS; Borsyra;

    Sammanfattning : Nuclear power plants generate electricity by means of splitting atoms. The basic safety requirements and objectives are to protect the people, society, and the environment from radiological accidents, limit harmful effects of ionizing radiation during operation and take all reasonable practical steps to prevent radiological accidents.

  4. 8. Numerical modeling of airflow on the cathode-side of a bipolar flow plate : How the formed geometry affects the pressure drop and flow distribution in a hydrogen fuel cell

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Olivia Johansson; [2023]
    Nyckelord :Performance; Cross-sectional geometry; Computational fluid dynamics;

    Sammanfattning : Climate change and rising temperatures is a well-known problem. To tackle global warming a transition from fossil fuels to renewable and reliable energy sources is necessary. Hydrogen, in fuel cells, is proposed to replace diesel and gasoline in the transport sector. LÄS MER

  5. 9. Design of components for High Flows

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Melvin Jobe; [2023]
    Nyckelord :;

    Sammanfattning : High-pressure-processing (HPP) is a method used to extend shelf life of foods and beverages. The process subdues the products to pressures of up to 6000 bar, which deactivates food pathogens and spoilage enzymes in just a few minutes, while maintaining the quality of the food. LÄS MER

    Sammanfattning : AstraZeneca är ett medicinskt företag lokaliserat i Södertälje som har cirka 900 luftfilterboxar hos sin anläggning i Gärtuna. Dessa filterboxar kan vara opraktiska att hålla koll på eftersom de är utspridda uppe på vindarna, samt att det behövs bra framförhållning vid filterbyten eftersom vissa filter innehåller farliga ämnen.
