  1. 11. Optical Emission Spectroscopy Pulse Distribution Analysis on Steel Production Samples : Accuracy, sample variation, spread in different samples and steel grades/routes

    Master-uppsats, KTH/Materialvetenskap

    Författare :Paulo Urrea Molina; [2023]
    Nyckelord :;

    Sammanfattning : This thesis work aimed to contribute to the development of online characterization techniques for non-metallic inclusions in steelmaking. The study focused on assessing the precision and accuracy of the optical emission spectroscopy pulse distribution analysis (OES/PDA) technique using asreference light optical microscope (LOM) and scanning electron microscope(SEM).

  3. 12. Investigations of Tool Wear Mechanisms in the Turning of Conventional, Calcium Treated and Ultraclean Steels

    Master-uppsats, KTH/Materialvetenskap

    Författare :Milou Göransson; [2023]
    Nyckelord :Clean steel; Ultraclean steel; Longitudinal turning; Cemented carbide cutting tool; Chemical vapor deposition coating; Machinability; Tool wear; Non-metallic inclusions; Rent stål; Ultrarent stål; Längdsvarvning; Hårdmetall skärverktyg; Kemisk ångdeponering beläggning; Bearbetningsbarhet; Verktygsslitage; Icke-metalliska inneslutningar.;

    Sammanfattning : Application of clean and ultraclean steels have shown to provide favourable mechanical properties for bearings and transmission components, specifically regarding fatigue performance, compared to conventional steel grades. Clean steels are characterized by containing a very low level of non-metallic inclusions. LÄS MER

  4. 13. Utmaningar och pedagogiska metoder inom spektrumet social inkludering i ämnet idrott och hälsa: Med fokus på funktionsnedsatta elever och elever etniskkulturella minoritetsgrupper

    Kandidat-uppsats, Örebro universitet/Institutionen för hälsovetenskaper

    Författare :Robin Celik; Johan Razai; [2023]
    Nyckelord :En skola för alla; exkludering; etnicitet; funktionsnedsättning; integrering;

    Sammanfattning : Introduktion: Inom ämnesområdet idrott och hälsa utgör social inkludering en betydandeutmaning. Styrdokumenten framhåller att pedagoger har ett ansvar att skräddarsy sinundervisning i enlighet med varje elevs unika behov och förutsättningar. LÄS MER

  5. 14. The Impact of Targeted Memory Reactivation on Declarative Memory During Slow-Wave Sleep : A Systematic Review

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Julia Lundgren; [2023]
    Nyckelord :targeted memory reactivation; TMR; sleep; slow-wave sleep; SWS;

    Sammanfattning : The method targeted memory reactivation (TMR) uses specific stimulation when subjects are completing tasks and during sleep. The TMR process is known to influence the consolidation of declarative memories. The aim of this thesis is to conduct a systematic review on the effects of TMR on declarative memory consolidation during slow-wave sleep (SWS). LÄS MER

  7. 15. Iron Pieces from The Copper Wreck : An archaeometallurgical analysis of iron bars, billets and osmund iron found in Gdansk, Poland

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Mikael Ghaysari; Benjamin Tiberghien; Maximilian Åkerblom Jonsson; [2022]
    Nyckelord :The Copper wreck; W5; Miedsiowiec; Osmund; Slag analysis; SEM; EDS; LOM; Medieval iron production; Blast furnace; Indirect reduction; Direct reduction; Kopparvraket; W5; Miedsiowiec; Osmund; Slagg; SEM; EDS; LOM; Medeltida järnproduktionen; Masugn; Indirekt reduktion; Direkt reduktion;

    Sammanfattning : The topic of osmund iron is of great interest in both historical and metallurgical perspective. Between the 14th and the 17th century osmund iron was exported extensively from Sweden but it has been difficult to characterize and confirm what exactly osmund iron is. LÄS MER
