  1. 21. SAR Remote Sensing of Forests, from Microwaves to VHF

    Författare :Hans Israelsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microwave; backscattering models; SAR; VHF; vegetation;

    Sammanfattning : The number of SAR systems available for civilian remote sensing purposes has grown in the nineties. A Synthetic Aperture Radar produces high resolution images of the earth independent on daylight and atmospheric conditions. This thesis mainly examines the applications of SAR remote sensing to monitoring forested areas. LÄS MER

  3. 22. Urodynamic evaluation of detrusor pressure and blood pressure reaction in patients with a reflux urinary bladder after spinal cord injury

    Författare :Mikael Thyberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : This thesis is focused on urodynamic evaluation of variables that are associated with the risk of upper urinary tract dysfunction and autonomic dysreflexia in patients with a reflex urinary bladder after spinal cord injury. The detrusor pressure was measured with suprapubic catheters during 24 or 12 hours of physiological filling (diuresis) and during consecutive cystometries. LÄS MER

  4. 23. Materials aspects in spin-coated films for polymer photovoltaics

    Författare :Ana Sofia Anselmo; Ellen Moons; Krister Svensson; Jan van Stam; Paul Dastoor; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; materials science; photovoltaics; conjugated polymer; polymer solar cell; bulk heterojunction; coating; morphology; fullerene; photostability; degradation; X-ray absorption spectroscopy; synchroton-based techniques; Materialvetenskap; Materialvetenskap;

    Sammanfattning : Polymer-based photovoltaics have the potential to contribute to boosting photovoltaic energy conversion overall. Besides allowing large-area inexpensive processing, polymeric materials have the added benefit of opening new market applications for photovoltaics due to their low-weight and interesting mechanical properties.

  5. 24. Magnetization Dynamics in Ferromagnetic Thin Films : Evaluation of Different Contributions to Damping in Co2FeAl and FeCo Film Structures

    Författare :Serkan Akansel; Peter Svedlindh; Olof Karis; Erik Wahlström; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spintronics; Gilbert damping parameter; magnetization dynamics; ferromagnetic resonance; Heusler alloys; magnetic thin films; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : Static and dynamic magnetic properties of Co2FeAl and Fe65Co35 alloys have been investigated. Co2FeAl films were deposited at different temperatures and the deposition parameters were optimized with respect to structural and magnetic properties. As a result, a film with B2 crystalline phase was obtained without any post-annealing process. LÄS MER

  7. 25. Exploiting genomic information on purebred and crossbred pigs

    Författare :André Hidalgo; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The use of genomic information has become increasingly important in a breeding program. In a pig breeding program, where the final goal is an increased crossbred (CB) performance, the use of genomic information needs to be thoroughly evaluated as it may require a different strategy of what is applied in purebred (PB) breeding programs.
