  1. 21. Different neurophysiological methods for studying the vestibular system : evaluation of old methods and development of a new test procedure

    Författare :Birgitta Larsby; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Different methods were used to study the physiology and anatomy of the vestibular system. 1) A primary vestibular cortical area in the cat was located and tested for somatosensory inflow by recordings of vestibular evoked potentials and extracellular single unit activity.

  3. 22. New techniques in liver surgery

    Författare :Ulf Jersenius; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The development of liver surgery has a long history and through the years, much knowledge has been gathered concerning various aspects of the liver. The exploration and understanding of liver anatomy and liver regeneration and development of surgical techniques are important landmarks. LÄS MER

  4. 23. Internal Dosimetry Development and Evaluation of Methods and Models

    Författare :Lena M Jönsson; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; Klinisk fysiologi; medical instrumentation; tomography; radiology; Clinical physics; crypt cells; intestine; radionuclide; scintillation camera; sestamibi; activity quantification; conjugate view method; Monte Carlo simulation; internal dosimetry; Nuclear medicine; radiobiology; Nukleärmedicin; radiobiologi; medicinsk instrumentering; radiologi;

    Sammanfattning : Radionuclide therapy requires patient-specific planning of the absorbed dose to target volumes, in most cases tumours, in order to achieve an expected biological effect, taking into account that the absorbed doses to normal organs and tissues should be kept as low as reasonably achievable. Therefore, the calculation of absorbed doses has to be as accurate as possible. LÄS MER

  5. 24. Exceptional fossil preservation: implications for palaeobiology and taphonomy

    Författare :Miriam Heingård; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; exceptional preservation; molecular palaeontology; palaeobiology; taphonomy; braincase; cuticle; fish larvae; Fur Formation; Stolleklint Clay; melanin; systematics;

    Sammanfattning : Although fossils are relatively common in some sedimentary deposits, the majority consists of fragmented or distorted skeletal hard parts (such as shell and bones). However, in rare cases, special burial and diagenetic conditions have allowed a greater portion of the original anatomy to be incorporated into the fossil record. LÄS MER

  7. 25. Palaeobiology and taphonomy of early problematic fossils

    Författare :Mónika Marti Mus; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Historical Geology and Paleontology; Historisk geologi och paleontologi;

    Sammanfattning : Extinct organisms that cannot be accommodated in any extant phylum are generally referred to as "problematic fossils". They are more numerous in progressively older strata and constitute an important part of the late Proterozoic and early Palaeozoic biota. LÄS MER
