  1. 1. On-chip Ultrasonic Sample Preparation

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Ida Sadat Iranmanesh; KTH.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ultrasound; Sample preparation; Particle manipulation; Physics; Fysik; Biologisk fysik; Biological Physics;

    Abstract : Acoustofluidics has become a well-established technology in the lab-on-a-chip scientific community. The technology involves primarily the manipulation of fluids and/or particles in microfluidic systems. READ MORE

  2. 2. On healing after periapical surgery and different retrograde root-filling materials. A clinical and histological study

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Dan-Åke Wälivaara; Göteborgs universitet.; Gothenburg University.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; periapical surgery; ultrasonic preparation; IRM; thermoplasticized gutta-percha; Super-EBA; mineral trioxide aggregate; root-filling status; lesion size; lesion type;

    Abstract : Aims: The outcome from conventional endodontic therapy does not always result in a healing of the periapical area, thus leaving a remaining lesion with or without symptoms. The primary treatment alternative is a revision of the orthograde root-filling if applicable. A second treatment alternative might be a periapical surgery procedure. READ MORE

  3. 3. Towards a new sensing strategy for measuring paper pulp properties a combination of ultrasonic and optical measurement techniques

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Jan Niemi; Luleå tekniska universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : In the manufacturing process of paper the mass fraction and material properties of the fibres in the pulp suspension are important for the strength and quality of the finished product. The properties of the fibres in the pulp suspension that enters the paper machine is not well understood and therefore an adequate prediction of the strength and quality of the finished paper is not possible.
