  2. 1. On wear in rolling/sliding contacts

    Author : Rickard Nilsson; Ulf Olofsson; I. Sherrington; KTH; []
    Keywords : Technology; wear; rolling; sliding; contact; environment; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The aim of this thesis is to increase the understanding of wear in rolling/sliding contacts such as the wheel-rail contact for railroads and the roller-washer contact for roller bearings. The Stockholm commuter train network has been the subject of papers A and B in this thesis in which the wear and surface cracks on rails has been observed for a period of three years. READ MORE

  4. 2. Tribology of hydraulic motor

    Author : Daniel Nilsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : A radial piston hydraulic motor has several components involving sliding or rolling interfaces which may encounter tribological problems. Seizure is one of them and it results in complete stoppage of motion between the relatively moving components and has serious consequences in terms of the operation of a hydraulic motor. READ MORE

  5. 3. High-Tc SQUIDs for magnetophysiology - development of a magnetometer system and measurements of evoked fields from hippocampal neurons in vitro

    Author : Per Magnelind; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; neuromagnetism; brain slice; neurophysiology; electrophysiology; hippocampus; biomagnetism; SQUID;

    Abstract : This thesis concerns development of a system based on a high-transition-temperature superconducting quantum interference device (high-Tc SQUID) magnetometer. The system has been designed and used for magnetic field recordings from brain slices, i.e. magnetophysiology. READ MORE

  6. 4. Anterior shoulder dislocation : Aspects of alternative methods of treatment and MR imaging

    Author : Göran Wintzell; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Shoulder; traumatic primary dislocation; arthroscopic lavage; non-operative regime; Indirect MR arthrography; apprehension position; ABER position; Bankart operation; Kirurgi; Surgery; Kirurgi; Orthopaedics; ortopedi;

    Abstract : Sixty patients (16-30 years) with traumatic primary anterior shoulder dislocation were allocated to arthroscopic lavage or non-operative treatment. The arthroscopic lavage group had a lower recurrence rate, better functional outcome and anterior stability after one year. READ MORE

  7. 5. Evaluation of Splitting Capacity of Bottom Rails in Partially Anchored Timber Frame Shear Walls

    Author : Giuseppe Caprolu; Ian Smith; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : The horizontal stabilization of timber frame buildings is oftenprovided by shear walls. Plastic design methods can be used todetermine the load-carrying capacity of fully and partially anchoredshear walls. In order to use these methods, a ductile behaviour of thesheathing-to-framing joint must be ensured. READ MORE
