  1. 1. PLASTER CASTS AND CORROSION AN EXPERIMENTAL STUDY ON REMOVAL OF CORROSION PRODUCTS FROM PLASTER CASTS

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Gabriella Zimmerman; [2023-11-07]
    Keywords : plaster cast conservation; iron corrosion staining; xanthan gel; Arbocel®; latex cleaning; chelating agents;

    Abstract : Conservation of plaster casts is complex due to the nature of the material itself. Corrosion of armature and metal structural supports is one of the most common causes of damage in plaster casts and subsequent corrosion staining. READ MORE

  3. 2. Dairy cow copper status in molybdenum rich areas : focus on copper excretion in faeces, urine and milk

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Lisa Stensson; [2023]
    Keywords : dairy cow; ruminant; copper; molybdenum; antagonist; excretion;

    Abstract : Koppar (Cu) är ett essentiellt spårämne med flertalet funktioner hos idisslare men både över- och underutfodring kan ha negativa effekter på djurets hälsa och produktion. Utöver det interagerar Cu med andra mineraler i våmmen vilket minskar tillgängligheten av Cu i tunntarmen. READ MORE

  4. 3. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength

    University essay from KTH/Tillämpad fysik

    Author : Alexandros Bampis; [2023]
    Keywords : Nanophotonics; Quantum Dot Positioning; Photoluminescence Mapping; Scanning Microscope; Nanofotonik; Positionering av kvantprickar; Fotoluminescenskartläggning; Skanningsmikroskop;

    Abstract : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. READ MORE

  5. 4. Application of harmonic injection method to analyse Sub-Synchronous Control Interactions (SSCI)

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Linus Eriksson; [2022]
    Keywords : Sub-synchronous control interaction SSCI ; damping of SSCI; DFIG; PSCAD; Power Oscillation Damper POD ; Harmonic Injection; Subsynkrona kontrollinteraktioner SSCI ; dämpning av SSCI; DFIG; PSCAD; Dämptillsats POD ; Harmonisk Injection;

    Abstract : Wind farms are commonly connected to the main grid through compensated lines which increases the power transfer capability of the line. Double Fed Induction Generator (DFIG) wind turbines in connection to compensated lines can experience Sub-Synchronous Control Interaction (SSCI) which can bring system quantities above allowed levels.

  6. 5. Damping of sub-synchronous control interactions with a STATCOM : Wind farms & series compensated power lines

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Leonardo Alvarez Urrutia; [2022]
    Keywords : Sub-Synchronous Control Interactions; Power Systems; STATCOM; Network Stability; Doubly-Fed Induction Generator; Impedance-Based Stability Analysis;

    Abstract : The power converter is one of the key components in power system applications such as high voltage direct current (HVDC) systems and the grid connection of intermittent sources such as wind and solar power. However, the increased penetration of converter-based generation introduces challenges, such as sub-synchronous interaction between the converter control system and the grid. READ MORE
