  1. 16. Modeling glioblastoma growth patterns and their mechanistic origins

    Författare :Emil Rosén; Sven Nelander; Rebecka Jörnsten; Philip Gerlee; Kristin Swanson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; glioblastoma; invasion; image analysis; neural networks; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik; Oncology; Onkologi; Molekylär medicin; Molecular Medicine;

    Sammanfattning : Glioblastoma (GBM) is the most common and aggressive primary brain cancer. GBM cells migrate away from the primary lesion and invade healthy brain tissue. The invading cells escape surgical resection, radiotherapy and develop resistance to chemotherapy. Consequently, despite treatment, recurrence is inevitable, and survival is only 14 months. LÄS MER

  3. 17. Connecting CMR and Physiology : Expanding the capabilities of cardiovascular magnetic resonance in quantifying physiology

    Författare :Felicia Seemann; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulär magnetresonanstomografi; Fysiologi; Atrioventrikulär klaffplansrörlighet; Mitralisflöde; Tryck-volym loopar; Kraft-längd loopar; Cardiovascular magnetic resonance; Physiology; Atrioventricular plane displacement; Transmitral flow; pressure-volume loops; Ventricular force-length loops;

    Sammanfattning : The assessment of cardiovascular physiology is crucial to facilitate clinical diagnostics, treatment, and research. Physiology and anatomy can be assessed noninvasively using cardiovascular magnetic resonance (CMR), a versatile and reliable medical imaging modality free from ionizing radiation. LÄS MER

  4. 18. Computational Studies of Cellulose-based Materials

    Författare :Jiu Pang; Igor Zozoulenko; Alexandar Mehandzhiyski; Sergei Popov; Maria Sammalkorpi; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Cellulose is a remarkable organic biopolymer and sustainable raw material existing in nature. Over the past several decades, the study of cellulose materials has attracted significant attention in chemistry, physics, biomedicine, and engineering fields. LÄS MER

  5. 19. Multi-Scale Surface Water-Groundwater Interaction : Implications for GroundwaterDischarge Patterns

    Författare :Babak Brian Mojarrad; Anders Wörman; Joakim Riml; Jan Fleckenstein; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; groundwater flow; hyporheic zone; multi-scale modeling; spectral analysis; fragmentation of discharge zones; characteristic parameters; Hydraulik och teknisk hydrologi; Hydraulic and Hydrologic Engineering;

    Sammanfattning : Rivers and aquifers are continuously exchanging water, driven by processes that occur on various temporal and spatial scales, ranging from small streambed features to large geological structures. The interaction between these two components occurs in permeable sediments below the stream channel, called the hyporheic zone. LÄS MER

  7. 20. Total internal reflection ellipsometry

    Författare :Michal Poksinski; Uwe´ Beck; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This thesis summarizes the work performed on the development and implementation of the optical measurement technique called total internal reflection ellipsometry (TIRE).The TIRE principle is based on spectroscopic ellipsometry performed under conditions of total internal reflection.
