  1. 21. Ultraljudsmätning av benens muskulatur : reliabilitet av tvärsnittsmätning hos häst

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Tina Hansen; [2021]
    Keywords : muskulatur; häst; ultraljud; tvärsnitt; repeterbarhet; reproducerbarhet; intrareliabilitet; interreliabilitet; ICC; rehabilitering;

    Abstract : Att mäta muskelutveckling kan vara användbart exempelvis för att monitorera hypertrofi i samband med prestationshöjande träning eller utvärdera muskelutveckling i samband med rehabilitering efter skada. Ultraljudsmätning har visats vara en snabb, enkel, repeterbar och tillförlitlig metod för att mäta muskulatur på människa och hund. READ MORE

  3. 22. State of the Art Report on Cement Based Grout Properties and Dynamic Grouting

    University essay from KTH/Jord- och bergmekanik

    Author : Bowen Meng; [2021]
    Keywords : Dynamic grouting; filtration; rheology; grouting phase;

    Abstract : Dynamic grouting in rock mass has been studied since 1985 while desired penetration in rock masses with fine fractures is still a challenge because of uncertainty and complexity in the grouting process. This has attracted the attention of researchers in different countries and regions, especially in some Nordic countries such as Sweden. READ MORE

  4. 23. Investigation of Light and Ultrasound Injected Signals in Microphones

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Robin Djerv; [2021]
    Keywords : LightCommands; DolphinAttack; MEMS Microphone; Signal Injection; Security;

    Abstract : Voice commanded systems (VCS) have been proved to be vulnerable to signal in- jections mimicking voice commands and explored security flaws in market avail- able products for the time of each respective study. Signal injection caused with the help of amplitude modulated ultrasonic waves (being known as DolphinAt- tacks - DA) were proved to work on several such devices in 2017. READ MORE

  5. 24. Dispersion of cement-based grout with ultrasound and conventional laboratory dissolvers

    University essay from KTH/Byggvetenskap

    Author : Antranik Karamanoukian; [2020]
    Keywords : ultrafine cement grout; microfine cement grout; dispersion; additives; ultrasound dissolver; laboratory dissolver; ultrafint cementbruk; mikrofin cementbruk; dispergering; tillsatser; ultraljud apparat; laboratorieblandaren;

    Abstract : In any underground facilities especially tunnels, it is essential to seal the area against water ingress and leakage of reserved materials. Grouting is a common method used to seal rocks around tunnels, successful grouting reduces the duration and cost of the construction, guarantees better working environment and higher safety, minimizes the maintenance and most important decreases the corresponding environmental hazards significantly.

  6. 25. Serumkoncentrationer av symmetriskt dimetylarginin hos katt : en pilotstudie

    University essay from SLU/Dept. of Clinical Sciences

    Author : Caroline Bergman; [2020]
    Keywords : katt; SDMA; symmetriskt dimetylarginin; kreatinin; kronisk njursjukdom;

    Abstract : Kronisk njursjukdom är ett vanligt förekommande sjukdomstillstånd hos framför allt äldre katter och även en vanlig orsak till avlivning hos katt. För att bedöma njurfunktionen hos katt analyseras vanligtvis koncentrationen av kreatinin i serum eller plasma, vilket är en enkel men relativt okänslig metod. READ MORE
