  1. 1. Thin lubricating films in elastohydrodynamic contacts : experimental techniques and applications

    Author : John Lord; []

    Abstract : The objective of the work reported in this thesis was to increase understanding of thin film lubrication in elastohydrodynamic (EHL) contacts. Increasingly stringent cost demands upon the manufacturing of lubricated machine elements coupled with new environmental requirements have created a need for this knowledge. READ MORE

  2. 2. Simulation and Experimental Methods for Characterization of Nonlinear Mechanical Systems

    Author : Martin Magnevall; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear structural dynamics; simulation; system characterization; experimental techniques; experimental methods;

    Abstract : Trial and error and the use of highly time-consuming methods are often necessary for investigation and characterization of nonlinear systems. However, for the rather common case where a nonlinear system has linear relations between many of its degrees of freedom there are opportunities for more efficient approaches. READ MORE

  3. 3. Experimental Neuroretinal Transplantation

    Author : Fredrik Ghosh; Lund Oftalmologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transplant; Retinal degeneration; Retina; Rabbit; Neural development; Immunohistochemistry; MHC; Ultrastructure; Vitrectomy; Ophtalmology; Oftalmologi;

    Abstract : Embryonic full-thickness rabbit neuroretinal sheets were transplanted to the subretinal space of adult hosts. This was accomplished by using a new transplantation technique involving vitrectomy and retinotomy. The grafts were followed from 10 to 306 days after surgery, and were then examined by different histological techniques. READ MORE

  4. 4. Dynamic Soil-Structure Interaction Analysis of High-Speed Railway Bridges : Efficient modeling techniques and Experimental testing

    Author : Abbas Zangeneh Kamali; Costin Pacoste; Raid Karoumi; Andreas Andersson; Pedro Galvín; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway bridge dynamics; Soil-structure interaction; Resonance; Analytical solution; Non-proportional damping; Complex mode; Field measurements; FE Model updating; Järnvägsbrodynamik; Jord-bro interaktion; Resonans; Analytisk lösning; Icke-proportionell dämpning; Komplex mod; Fältmätningar; FE Modelluppdatering; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Abstract : The work reported in this thesis presents a general overview of the resonant response of high-speed railway bridges considering soil-structure interaction. The study aims to identify the effect of the surrounding and underlying soil on the global stiffness and damping of the structural system. READ MORE

  5. 5. Atelectasis and gas exchange impairment after cardiopulmonary bypass : An experimental study

    Author : Lennart Magnusson; Uppsala universitet; []
    Keywords : Medical sciences; Lung: cardiopulmonary bypass; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

    Abstract : Despite of the improvement in management and equipment for cardiopulmonary bypass (CPB), postoperative pulmonary complications remain a major problem after cardiac surgery. In the present thesis, using a pig model, atelectasis has been tested as a cause of the increase in intrapulmonary shunt commonly seen after CPB. READ MORE
