  2. 1. Quantitative Modeling of Gain in Quantum Cascade Lasers under Operational Intensities

    Author : David Winge; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; non-linear response; quantum cascade lasers; modelling; Non-equilibrium Green s functions; Gain clamping; Fysicumarkivet A:2016:Winge; kvantkaskadlaser; terahertz; infrarött; Halvledarfysik; spektroskopi; simulering;

    Abstract : This thesis adresses modeling of quantum cascade lasers using non-equilibrium Green’s functions. Focus lies on the quantitative modeling of the gain when the systems are exposed to strong laser fields, as under realistic opertional conditions. READ MORE

  4. 2. Urinary catheter policies for short-term bladder drainage in hip surgery patients

    Author : Maria Hälleberg-Nyman; Ann Langius-Eklöf; Margareta Gustafsson; Jan-Erik Johansson; Ania Willman; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Urinary catheterisation; nosocomial urinary tract infection; hip fracture; hip arthroplasty; nursing; patient experiences; clamping; Vårdvetenskap; Nursing Science;

    Abstract : The overall aim of this thesis was to evaluate methods for urinary catheter handling in patients undergoing hip surgery. The intention was to gain knowledge in order to provide optimal and cost- effective care regarding urinary catheterisation in this group of patients. READ MORE

  5. 3. Improving neonatal health care in Nepal

    Author : Olivia Brunell; Mats Målqvist; Anna Bergström; Uwe Ewald; Debra Jackson; Uppsala universitet; []

    Abstract : Every year, millions of newborns die globally due to poor quality of care around the time of birth. The overall aim of this thesis was to inform and test design of quality improvement (QI) interventions in Nepal. READ MORE

  6. 4. Active control of vibration and analysis of dynamic properties concerning machine tools

    Author : Henrik Åkesson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Control; Modal Analysis; Analog Controller;

    Abstract : Vibration in internal turning is a problem in the manufacturing industry. Vibrations appear under the excitation applied by the material deformation process during the machining of a workpiece. READ MORE

  7. 5. Monitoring of Splanchnic Regional Perfusion : An Experimental Study of New Application and Validation

    Author : Itaru Koga; Lennart Christiansson; Lars Wiklund; Björn Biber; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; Splanchnic circulation; Regional ischemia; Hepatic artery buffer response; Air tonometry; Intraperitoneal; Reflectance pulse oximetry; Hepatic venous oxygen saturation; Lactate; PCO2 gap; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård;

    Abstract : Systemic infection, major surgery, trauma and many other causes can lead to impaired organ function. Compensated shock is not detected by global hemodynamic and oxygen measurements, as they take no account for regional variations. READ MORE
