  1. 1. Work Environment in the Operating Room during Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy : Factors Influencing Choice of Protective Equipment

    Författare :Sara Näslund Andréasson; Haile Mahteme; Helena Anundi; Christine Leo Swenne; Ulrica Nilsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Peritoneal carcinomatosis (PC) is a common metastatic manifestation of both gastrointestinal and gynecological malignancies. Curative modes of treatment are cytoreductive surgery (CRS) combined with intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC). LÄS MER

  3. 2. Power Quality Disturbances and Protective Relays

    Författare :Fan Wang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; overcurrent relays; component switching; frequency deviation; power system disturbance; protection algorithms; power quality; digital protective relays; impedance relays;

    Sammanfattning : This thesis combines knowledge from two areas: power quality and power system protection. Power quality concerns the effect of voltage disturbances on end-user equipment and of current disturbances on network components. Power system protection concerns the detection of faults in the system from measured voltages and currents. LÄS MER

  4. 3. The safety relevance of standardized tests for diving equipment

    Författare :Mårten Silvanius; Oskar Frånberg; Greg Murphy; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diving; rebreather; underwater breathing apparatus; unmanned testing; hyperbaric; scuba; oxygen sensor; composite gas cylinder; carbon dioxide monitoring;

    Sammanfattning : Vital components are more or less prone to fail in a diving apparatus. This thesis examines the performance of oxygen sensors, carbon dioxide scrubber monitoring and composite gas cylinders. LÄS MER

  5. 4. High-frequency noise in power grids, neutral and protective earth

    Författare :Martin Lundmark; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : This licentiate thesis deals with the high-frequency distortion, 1 kHz and higher, introduced into the power grid by the numbers of power converters in use today. These devices can be a source of electromagnetic interference and equipment damage despite the fact that the equipment complies product-standards testing. LÄS MER

  7. 5. Serious occupational injuries by "accidents" : possible means of prevention and injury mitigation

    Författare :Torgny Jarl; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Occupational; accident; injury; prevention; personal safety equipment; emergency action; commercial vehicles;

    Sammanfattning : An analysis of the circumstances preceding severe occupational injuries as a consequence of impacts has shown that well-known risks are of great importance in 75 per cent of the cases. This indicates that the subjective cause "neglect" is common. The negligence is distributed to the same extent among employers as among employees. LÄS MER
