  1. 21. Utveckling av Polydimetylsiloxan-Mikropartiklar för Biomedicinsk NMR

    Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Mohammad Al-Sultani; Josef Djärf; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Nuclear magnetic resonance spectroscopy is a technique for identifying molecular structures, compositions etc. and is widely used in many life science research fields. The purpose of this project is to synthesize PDMS microparticles with a magnetic susceptibility matching water, which makes them applicable for use in NMR of biological samples. LÄS MER

  3. 22. Design of a State-Of-The-Art Test Facility for Rocket Engines

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Akash Raja Meghavath; [2022]
    Nyckelord :Rocket architectures; oxidizer feed system; layout plan; safety precautions safety standards; test bed stand; static tests;

    Sammanfattning : The development of innovative propulsion systems requires testing in suitable facilities that reveal the efficacy of design models and allow for design refinement. The qualification process starts from ground tests and ends in vacuum chambers. LÄS MER

  4. 23. Invasionens första vecka : En kvantitativ innehållsanalys av Rysslands invasion av Ukraina 2022 i svenska nyhetsmedier

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för medier och journalistik (MJ)

    Författare :Sara Johansson; Lydia Håkansson; [2022]
    Nyckelord :Framing; conflict; news media; mass media; quantitative content analysis;

    Sammanfattning : News journalism is a great source of information about things that happen beyond our own reality. The need to take part in news is something that is increasing during a crisis and despite the development of social media and the internet, the traditional media still fulfill a socially important function.

    Nyckelord :Additive manufacturing; E-PBM; Inoculation; process parameters; TiN; CET;

    Sammanfattning : Electron Beam Powder Bed Fusion manufacturing of components is an additive manufacturing process that is complex and has widespread advantages for aerospace and many industrial processes. It reduces costs and has a larger powder particle size requirement. LÄS MER

  7. 25. Application and Evaluation of Current Guidelines for Metal Additive Manufacturing

    Master-uppsats, Lunds universitet/Innovation

    Författare :Robin Bergman; [2022]
    Nyckelord :additive manufacturing; laser powder bed fusion; thin-wall structures; design for additive manufacturing; design guidelines; Technology and Engineering;

    Sammanfattning : The goal of this thesis has been to evaluate the design guidelines that currently exist regarding designing for metal additive manufacturing (AM). More specifically, this project has focused on the design guidelines regarding thin-walled features and how well they work when applied to adapt an industrial part for manufacturing with the AM process laser powder bed fusion (L-PBF).
