  2. 1. 3D Occlusion Management and Causality Visualization

    Author : Niklas Elmqvist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; causality; occlusion reduction; interaction techniques; visualization; occlusion management; information visualization; causal relations;

    Abstract : This thesis is split into two parts: one part dealing with the management of occlusion in 3D environments, the other with the visualization of causal relations. Both of these parts fall within the general framework of visualization---the graphical representation of data (abstract or concrete) with the purpose of amplifying cognition---but they do so in different ways.

  4. 2. Carotid stenosis

    Author : Elias Johansson; Per Wester; Conny Arnerlöv; Arne Lindgren; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Carotid stenosis; Risk; Recurrence; Stroke; TIA; Near-occlusion; Carotid Endarterectomy; Delay; Panoramic Radiographs; Cardiovascular medicine; Kardiovaskulär medicin; Neurology; Neurologi; Internal Medicine; invärtesmedicin; neurologi; Neurology; odontologi; Odontology;

    Abstract : Carotid stenosis is one of several causes of ischemic stroke and entails a high risk of ischemic stroke recurrence. Removal of a carotid stenosis by carotid endarterectomy results in a risk reduction for ischemic stroke, but the magnitude of risk reduction depends on several factors. READ MORE

    Abstract : INTRODUCTION Stroke is a serious neurological disease which may lead to death and severe disability [1, 2]. There are two major types of stroke: ischemic and hemorrhagic stroke. READ MORE

  6. 4. Haemodynamic and ventilatory effects of laparoscopic surgery

    Author : Lena Andersson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Laparoscopy; C02 pneumoperitoneum; indicator- dilution technique; central haemodynamics; cardiac output; central blood volume; venous occlusion plethysmography; catecholamines; multiple inert gas technique; shunt; abdominal wall lift; intrathoracic pressure; ventilation-perfusion matching; atelectasis; spiral computed tomography.;

    Abstract : Background: It has been shown repeatedly that the establishment of pneumoperitoneum (PP) is associated with increased cardiac filling pressures, as well as increased blood pressure and systemic vascular resistance. Patients without heart or lung disease can compensate for these effects of PP, but cardiopulmonary compromised patients may develop cardiac failure during PP. READ MORE

  7. 5. The small intestine in experimental peritonitis : An experimental study focusing om intestinal energy metabolism, bacterial translocation and mucosal immunology

    Author : Mikael Ljungdahl; Uppsala universitet; []

    Abstract : The gut is highly susceptible to injury during sepsis. An impaired mucosal barrier permitstranslocation of enteric microorganisms to blood or other organs. In a porcine model sepsiswas induced by faecal peritonitis. READ MORE
