  1. 1. Ultrasonic Quantification of Skeletal Muscle Dynamics Feasibility and Limitations

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Frida Lindberg; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultrasound; skeletal muscle; intramuscular; dynamics; Tissue Doppler Imaging; Speckle Tracking; strain; quantification;

    Abstract : Pain and disorders of the human skeletal muscles are one of the most common reasons for medical consultations in the western countries today and there is a great need to improve both the understanding and treatment of several different muscular conditions.Techniques describing the muscle function in vivo are often limited by either their invasiveness or lack of spatial resolution.

    Abstract : Popular Abstract in Swedish Inom området diagnostisk nuklearmedicin används radioaktiva läkemedel som ges (administreras) till patienterna i syfte att diagnostisera ett antal olika sjukdomstillstånd. Då man tar fram nya radioaktiva läkemedel för användning inom diagnostisk nuklearmedicin handlar det många gånger om att uppskatta mängden av ett visst upptag av radiofarmakat i olika organ och vävnader i kroppen.

    Abstract : There is a large need for accurate methods detecting cardiovascular diseases, since they are one of the leading causes of mortality in the world, accounting for 29.3% of all deaths. READ MORE

  4. 4. Towards specific quantification of exosomes using surface-based sensing

    University dissertation from Chalmers University of Technology

    Author : Déborah L. M. Rupert; Chalmers tekniska högskola.; Chalmers University of Technology.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; antibody; binding rate; cluster of differentiation 63 CD63 ; concentration; diffusion; mass transport limited conditions; exosome; extracellular vesicles; label-free; liposome; nanoparticle tracking analysis; quantification; specific detection; surface-based biosensor; surface plasmon resonance.;

    Abstract : When exosomes were first observed in 1967, they were believed to be cell debris until extensive studies demonstrated key biological functionalities related to their composition and formation mechanism. Exosomes are nanometer-sized lipid vesicles of endocytic origin, with a membrane consisting of lipids and proteins and encapsulating a cargo composed of soluble proteins and genetic material.

  5. 5. Multiscale Methods and Uncertainty Quantification

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Daniel Elfverson; Uppsala universitet.; Uppsala universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multiscale methods; finite element method; discontinuous Galerkin; Petrov-Galerkin; a priori; a posteriori; complex geometry; uncertainty quantification; multilevel Monte Carlo; failure probability; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : In this thesis we consider two great challenges in computer simulations of partial differential equations: multiscale data, varying over multiple scales in space and time, and data uncertainty, due to lack of or inexact measurements.We develop a multiscale method based on a coarse scale correction, using localized fine scale computations.
