  1. 1. Impact of Residual Stress on the Warm Pre-Stressing Effect

    University essay from KTH/Hållfasthetslära

    Author : Emil Danielsson; [2023]
    Keywords : Warm Pre-Stressing effect; Residual stress; Cleavage fracture; Ferritic Steel; Fracture mechanics; Varm förspänning; Restspänningar; Klyvbrott; Brottmekanik; Ferritiskt stål;

    Abstract : Irradiation of a reactor pressure vessel (RPV) causes a shift of the ductile to brittle transition region towards higher temperature regions. In the event of a pressurized thermal shock (PTS), where the temperature drops drastically, the ductile to brittle transition region might be entered for irradiated ferritic steel. READ MORE

  3. 2. Effect of a plant-derived nutraceutical on the tolerance of axenically-cultured Artemia towards abiotic or biotic stressor

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Ahumuza Allan Castro; [2023]
    Keywords : Artemia; Hsp70; Vibrio campbellii; plant extract; aquaculture; abiotic stressor;

    Abstract : Aquaculture is one of the fastest-growing food-production industries worldwide accounting for almost half of fish used for human consumption. Super-intensive, intensive, and semi-intensive farming practices used to produce large farm fish are increasing the frequency of disease outbreaks which is a major problem affecting sustainable aquaculture growth.

  4. 3. Screw Joint Analysis in Radio Frequency Filters

    University essay from KTH/Industriell produktion

    Author : Nils Löwhagen; [2022]
    Keywords : Digital filter; Pre-load force; Clamp torque; Release torque; Surface roughness; Thermal shock test; Digitalt filter; Förspänningskraft; Klämvridmoment; Lossdragningsmoment; Ytjämnhet; Termiskt chocktest;

    Abstract : Filter devices are central elements of radio units utilized for modern-day telecommunication. Leakages of radio waves and passive intermodulation are evolving more prominent as the frequency bands become crowded. READ MORE

  5. 4. Classification of four mesosiderites and implications for their formation

    University essay from Lunds universitet/Geologiska institutionen

    Author : Gabriel Zachén; [2020]
    Keywords : mesosiderites; meteorites; stony-irons; classification; textures shock; emulsion; melt droplet; Lamont Acfer 265; QUE 86900; MAC 88102; Earth and Environmental Sciences;

    Abstract : Mesosiderites are rare stony-iron meteorites with enigmatic origins. Their unusual mix of crustal and core materials have inspired many formation theories over the last century. READ MORE

  6. 5. Electron heating in collisionless shocks observed by the MMS spacecraft

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Martin Svensson; [2018]
    Keywords : shocks; MMS; electron; heating; gradient; quasi-perpendicular; scaling; plasma; space;

    Abstract : Shock waves are ubiquitous in space and astrophysics. Shocks transform directed particle flow energy into thermal energy. As the major part of space is a collisionless medium, shocks in space physics arises through wave-particle interactions with the magnetic field as the main contributor.The heating processes are scale dependent.
