  1. 1. Acoustic Droplet Vaporization : An Assessment of How Ultrasound Wave Parameters Influence the Vaporization Efficiency

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Sara Öquist; [2020]
    Keywords : Acoustic Droplet Vaporization; Verasonics; Ultrasound; Vaporization Efficiency; Phase-change Contrast Agents;

    Abstract : Acoustic droplet vaporization (ADV) is a process in which a phase shift of a liquified droplet into a gaseous microbubble, is triggered using an ultrasonic wave. In contrast to utilizing conventional contrast agents in ultrasound, the phase change contrast agents used in ADV can extravasate into tumor tissue, and they offer a greater circulatory lifespan, thereby increasing the potential applications in which they can be utilized.

  2. 2. Development of Ultrasound Pulse Sequences for Acoustic Droplet Vaporization

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Isabelle Gouwy; [2019]
    Keywords : Ultrasound; Ultrasound contrast agents; Phase-change contrast agents; Acoustic droplet vaporization; Verasonics;

    Abstract : Ultrasound-mediated drug delivery has been proposed as a safe and non-invasive method to achieve localized drug release. Drug-loaded microbubbles are injected in the vascular system and ultrasound waves are then used to localize and burst the microbubbles at a specific targeted area. READ MORE

  3. 3. Electronic Structure Calculations of Amino Acids Under the Influence of Electric Fields

    University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Author : Christopher Prytz; [2018]
    Keywords : ;

    Abstract : By the use of highly intense X-ray pulses, with durations in the scale of tenths of fs, high resolutiondiffraction images of the structures of individual macro-molecules can be obtained. To generatea self-consistent 3D-image of the structures the diffraction images of thousands of copies of thesame molecules have to be compounded. READ MORE

  4. 4. Load-current response to severe changes of voltage

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Shuhan Ma; [2017]
    Keywords : ;

    Abstract : Electric loads, such as computers, lamps, refrigerators and heaters connected to low-voltage distributionsystems in homes and offices differ widely in how their current responds to changes in the applied voltage.These voltage changes could be a total collapse of the voltage, a weak or strong reduction of amplitude,or a sudden phase-shift.

  5. 5. Study on free-surface aeration with high-velocity air-water flows in open-channels

    University essay from KTH/Skolan för industriell teknik och management (ITM); KTH/Skolan för industriell teknik och management (ITM)

    Author : Belkiz Hasan; Paulo Monsalve; [2017]
    Keywords : ;

    Abstract : China’s biggest source of the renewable energy is hydropower, with a share of 85 %, in 2013, of the total renewable power generation. For the tenth sequential year, China has maintained the country’s leading role in global hydropower development by installing more hydropower plants than the rest of the world combined. READ MORE
