  1. 1. Tandstensborttagning med ultraljudstandborste : en pilotstudie

    University essay from SLU/Dept. of Clinical Sciences

    Author : Lina Dolfei; Molly Lavesson; [2023]
    Keywords : CleanyTeeth; emmi-pet; hund; munhälsa; plack; parodontal sjukdom; tand; tandborstning; tandsten; tandvård; veterinärmedicinsk tandvård;

    Abstract : Tandsten är ett vanligt förekommande problem hos våra hundar. Tandsten i sig är inte patologiskt men främjar fortsatt tillväxt av plack och bakterier vilket kan leda till parodontal sjukdom. READ MORE

  3. 2. Characterization of Pressure and Velocity Fields in Acoustophoresis Using Particle Tracks

    University essay from KTH/Tillämpad fysik

    Author : Jonathan Karlsson; [2023]
    Keywords : Acoustofluidics; Acoustophoresis; Ultrasonic Standing Waves; Acoustic fields; Particle tracking; Bio marking; Akustofluidik; Akustofores; Stående Ultraljuds Vågor; Akustiska fält; Particle tracking; Bio-markering;

    Abstract : This master’s thesis explores the possibility of calculating and using the pressure andvelocity fields responsible for acoustophoresis. The goal was to use simulated data,similar to two-dimensional particle tracks from a specific microfluidic platform, toestimate the force potential and solve the partial differential equation (PDE) thatgoverns the relationship between the force potential and the acoustic fields.

  5. 4. Bacteria in the vagina during the estrous cycle in mares

    University essay from SLU/Dept. of Clinical Sciences

    Author : Timjan Åkerholm; [2023]
    Keywords : artificial insemination; bacteriology; breeding; embryo transfer; equine reproduction; estrous cycle; ovulation; stud farm; vagina;

    Abstract : An understanding of the normal bacterial flora of any organ is essential to provide the background to conditions and interventions that might cause the flora to change. In the vagina of the mare, a change of bacterial flora could be induced by introduction of semen, treatment with antibiotics, backflow from an unhealthy uterus etc. READ MORE

  6. 5. Evaluation of Crack Depth Meter - An investigation of the crack depth meters possibilities and limitations for commonly occurring damage mechanisms

    University essay from KTH/Hållfasthetslära

    Author : Alfred Norberg; [2023]
    Keywords : Crack depth measurement; RMG 4015; ACPD; Damage Mechanism; Evaluation; FEM Simulation; Sprickdjupsmätning; RMG 4015; ACPD; Skademekanism; Utvärdering; FEM-simulering;

    Abstract : In this master thesis, the accuracy of the crack depth meter RMG 4015 was evaluated for different types of cracks with various damage mechanisms. In total, 61 crack depth measurements were conducted with the crack depth meter on 56 cracks which were located in the 23 different test pieces supplied by Kiwa. READ MORE
