  1. 16. Comparing different methods of measuring particle size for pharmaceutical excipients

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

    Author : Jiawen Wang; [2022]
    Keywords : particle size; comparison; Malvern analysis; Qicpic analysis; Pharmaceutical technology; Technology and Engineering;

    Abstract : In pharmaceutical science, particle size is one of the most fundamental parameters of materials, but different particle-sizing analysis methods lack a uniform standard for measuring irregular particle size, making it difficult to compare the accuracy and applicability of different particle-sizing analysis methods. Experiments on excipients used in pharmaceuticals are carried out in this paper by laser diffraction analysis (Malvern wet and dry), dynamic image analysis (Qicpic), and microscopic methods (Qicpic, SEM, and light microscopy) to determine the applicability and limitations of each method, as well as to clarify their advantages and disadvantages.

  3. 17. Large-Scale Atmospheric Drivers of Extreme Temperature Anomalies During Springtime in the Arctic

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

    Author : Linnea Barreng; [2022]
    Keywords : Meteorology; Temperature extremes; Arctic; Jet stream; Rossby waves; Spring; Meteorologi; Arktis; Extremväder; Jetström; Rossbyvågor; Vår;

    Abstract : In this project warm extreme temperature events in the Arctic region during the spring months March, April and May were identified and analysed. In the analysis daily average NCEP reanalysis data from NOAA/OAR/ESRL PSL format was used. READ MORE

  4. 18. Studies of Dark Showers for Present and Future Colliders

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Nicoline Krogh Hemme; [2022]
    Keywords : high-energy particle physics; dark matter; collider physics; beyond the standard model; Physics and Astronomy;

    Abstract : In this work we explore a strongly-interacting dark sector with a Z’ portal to the Standard Model. We focus on the dark shower phenomenology and their semi-visible jet signatures with a strong emphasis on first principles of the theory. READ MORE

  5. 19. LES modelling of spray combustion

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Arvid Åkerblom; [2021]
    Keywords : Gas Turbine; CFD; Large Eddy Simulation; Lagrangian Particle Tracking; Chemical Kinetics; Reaction Mechanism; Combustion; OpenFOAM; CHEMKIN; Technology and Engineering;

    Abstract : Computational fluid dynamics is a powerful method for understanding the flow and combustion that occurs inside aircraft engines and will be a key tool in the transition from conventional fossil-based fuel to sustainable alternatives. Because conventional fuels have been more widely researched, an attempt at simulating the combustion of alternative fuels should be preceded by the development of a method that is capable of accurately simulating the combustion of a conventional fuel.

  6. 20. Aviation’s future energy requirements

    University essay from Lunds universitet/Trafikflyghögskolan

    Author : Leonard Holmgren Holm; [2021]
    Keywords : Aviation fuels; Sustainable aviation fuels; Hydrogen power; Electric aircraft; Environmental impact; FLYL01; Technology and Engineering;

    Abstract : Flygindustrin närmar sig ett vägval där sektorn kommer behöva bestämma sig för vilken typ av framtida energimöjligheter den ska använda sig av. En väg är att även fortsättningsvis använda sig konventionellt flygbränsle vilket med stor sannolikhet kommer leda till fortsatt ökande utsläpp globalt, och den andra vägen leder sektorn till hållbart flygbränsle, vätgasdrift och batteridrivna elektriska flygplan.
