  1. 1. Microscopic Dynamics and Structure of some Polymer-based Electrolytes

    Författare :DANIEL ANDERSSON; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; segmental motion; neutron scattering; ionic conduction; polymer electrolytes; gel electrolytes; Gaussianity; oligomers; photon correlation; PPO-LiClO4;

    Sammanfattning : The electrolyte is a key component in high-capacity lithium batteries and there is a large demand for improved materials to increase the performance. Polymer-based electrolytes offer advantages in the design of safer and lighter batteries. LÄS MER

  4. 3. Lumbar disc herniation. Clinical outcome and segmental stability using a new radiological classification and radiostereometry

    Författare :Klas Halldin; Göteborgs universitet; []
    Nyckelord :lumbar disc herniation; discectomy; radiostereometry; segmental stability; instability; surgical outcome; radiological classification;

    Sammanfattning : Satisfactory results following conventional lumbar discectomy have been reported in 70-90% of cases. Remaining or recurrent low back pain or sciatica is, however, seen in many patients for reasons not yet fully understood. A relationship has previously been shown between the morphologic characteristics, i.e. LÄS MER

  5. 4. Assessment of 3D movements in the lumbar and cervical spine with a new CT based method

    Författare :Per Svedmark; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Numerous methods for measuring segmental motion in spine have been described. However, because of the inaccessibility of the spine and the complexity of segmental movements, most of the noninvasive methods in use today have low accuracy or are unable to detect movements in all three cardinal axes.

  7. 5. Transesophageal Echocardiography in Patients Undergoing Elective Coronary Artery Bypass Surgery

    Författare :Ingrid Palmgren; Russell Anderson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; transesophageal echocardiography; low-dose dobutamine; viability; coronary artery bypass; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; anestesiologi; Anaesthesiology;

    Sammanfattning : Transesophageal echocardiography (TEE) has become a useful tool in monitoring the heart in patients during open-heart surgery. This study was undertaken to evaluate whether it is feasible to use TEE to assess left ventricular myocardial viability in anesthetized patients scheduled for coronary artery bypass grafting (CABG).
