  3. 2. Surgery versus nonsurgical treatment of cervical radiculopathy. Randomized studies of anterior cervical decompression and fusion followed by physiotherapy versus structured physiotherapy alone

    Författare :Markus Engquist; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cervical radiculopathy; long term; cervical disc degeneration; outcome; ACDF; surgery; physical therapy; physiotherapy; RCT; randomized;

    Sammanfattning : Background and aims: Cervical radiculopathy (CR) is a symptom complex comprising neck pain and radiating arm pain due to compression of one or more cervical nerve roots, caused by spondylotic narrowing of the intervertebral foramina, intervertebral disc herniation or both. Anterior cervical decompression and fusion (ACDF) is a common surgical procedure to treat CR, but the evidence supporting use of this method versus nonsurgical treatment is scarce. LÄS MER

  4. 3. Clinical Bedside Studies of Cerebral Blood Flow in Severe Subarachnoid Hemorrhage Using Xenon CT

    Författare :Henrik Engquist; Per Enblad; Elham Rostami; Anders Lewén; Marianne Juhler; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Subarachnoid hemorrhage; delayed cerebral ischemia; cerebral blood flow; HHH-therapy; triple-H; xenon CT; XeCT; cerebral microdialysis; Neurokirurgi; Neurosurgery;

    Sammanfattning : Aneurysmal subarachnoid hemorrhage (SAH) is frequently complicated by delayed cerebral ischemia (DCI), contributing to poor outcome. Particularly for patients in poor neurological state, prediction of the acute clinical course is difficult, as is the early detection of DCI. LÄS MER

  5. 4. Dualities, Symmetries and Unbroken Phases in String Theory : Probing the Composite Nature of the String

    Författare :Johan Engquist; Joseph Minahan; Charlotte Kristjansen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Theoretical Physics; String Theory; M-Theory; Higher Spin Gauge Theory; Super Yang-Mills Theory; Anti-de Sitter Spacetime; Singletons; Massless Higher Spin Gauge Fields; AdS CFT Correspondence; Spin Chains; Semiclassical Strings; Tensionless Limits; Conformal Symmetry; Supersymmetry; Higher Spin Gauge Symmetry; Integrability; Fysik; Physics; Fysik;

    Sammanfattning : The thesis treats aspects of string/M-theory in anti-de Sitter spacetimes and their supersymmetric completions. By applying the AdS/CFT correspondence, as well as models of spin chains and singletons, we try to attain a better understanding of the underlying symmetries and the unbroken phases of string/M-theory.

  7. 5. Boundary and Interface Conditions for Electromagnetic Wave Propagation using FDTD

    Författare :Jon Häggblad; Björn Engquist; Olof Runborg; Thomas Rylander; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Numerical analysis; Numerisk analys;

    Sammanfattning : Simulating electromagnetic waves is of increasing importance, for example, due to the rapidly growing demand of wireless communication in the fields of antenna design, photonics and electromagnetic compatibility (EMC). Many numerical and asymptotic techniques have been developed and one of the most common is the Finite-Difference Time-Domain (FDTD) method, also known as the Yee scheme. LÄS MER
