  3. 2. Dual-modality probe for prostate cancer detection by combining Raman spectroscopy and tactile resonance technology

    Författare :Morgan Nyberg; Tomas Jansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical Engineering for Healthcare; Medicinsk teknik för hälsovård;

    Sammanfattning : Prostate adenocarcinoma, or prostate cancer (PCa), is the most common type of cancer and the leading cause of cancer-related deaths for men in Sweden and Europe. Radical prostatectomy (RP) is the most common curative treatment for PCa. This is a surgical procedure where the entire prostate is removed. LÄS MER

    Författare :Tomas Vikner; Anders Wåhlin; Anders Eklund; Jan Malm; Lars Nyberg; Susanne Schnell; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; 4D flow MRI; medical image analysis; cerebral hemodynamics; arterial pulsatility; DCE MRI; blood-brain barrier; white matter lesions; perivascular spaces; cerebral small vessel disease; hippocampus; cognition; aging; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

    Sammanfattning : 4D flow magnetic resonance imaging (MRI) is increasingly recognizedas a versatile tool to assess arterial and venous hemodynamics. Cerebral arterial pulsatility is typically assessed by analyzing flow waveforms over the cardiac cycle, where flow amplitude is a function of cardiac output, central arterial stiffness, and cerebrovascular resistance and compliance.

  5. 4. Epitaxy of oxide and nitride thin films grown by magnetron sputtering

    Författare :Faezeh Alijan Farzad Lahiji; Per Eklund; Arnaud Le Febvrier; Biplab Paul; Tomas Nyberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The need for electronic devices with new functionalities has caused research to move in a way to design and utilize materials with high-performance thermoelectricity, widely used in batteries, sensors, and electronic devices. Two-dimensional materials (2D) with unique structures and remarkable properties have been identified to fabricate oxide heteroepitaxy. LÄS MER

  7. 5. The Importance of Controlling Composition to Tailor the Properties of Magnetic Thin Films

    Författare :Andreas Frisk; Gabriella Andersson; Tomas Nyberg; Erik Johansson; Sarah Thompson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; FeNi; L10; X-ray diffraction; magnetic anisotropy; magnetron sputtering; thin film; permanent magnets; combinatorial materials science; amorphous materials; magnetic properties of thin films; chemical order; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : Many physical properties, for example structural or magnetic, of a material are directly dependent on elemental composition. Tailoring of properties through highly accurate composition control is possible in thin films. This work exemplifies such tailoring. LÄS MER
