  1. 1. Structured management of patients with suspected acute appendicitis

    Författare :Manne Andersson; Roland Andersson; Conny Wallon; Ari Leppäniemi; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background. Acute appendicitis (“appendicitis”) is one of the most common abdominal surgical emergencies worldwide. In spite of this, the diagnostic pathways are highly variable across countries, between centres and physicians. This has implications for the use of resources, exposure of patients to ionising radiation and patient outcome. LÄS MER

  3. 2. Appendicitis : Epidemiology and diagnosis

    Författare :Roland Andersson; Lars Holmberg; Linköpings universitet; []
    Nyckelord :appendicitis; epidemiology; etiology; diagnosis; natural history; appendectomy; MEDICINE; MEDICIN;

    Sammanfattning : The study concerns appendicitis, its epidemiology and diagnosis, and the outcome of appendectomy. A population based cohort of 9,274 patients undergoing appendectomy in 1969 to 1990 in Jönköping County was retrospectively studied, and 502 patients admitted for suspected appendicitis to the hospitals in Jönköping and Eksjö between October 1992 and December 1993 were prospectively studied.

  4. 3. The Nothing That Is : The Structure of Consciousness in the Poetry of Wallace Stevens

    Författare :Daniel Andersson; Bengt Landgren; Roland Lysell; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Literature; Wallace Stevens; Edmund Husserl; Jean-Paul Sartre; phenomenology; existentialism; thematic criticism; theme; image; modernist poetry; romantic poetry; Litteraturvetenskap; Literature; Litteraturvetenskap; Literature; litteraturvetenskap;

    Sammanfattning : This is a study of the poetry of the American writer Wallace Stevens (1879-1955). Stevens’ poetry is often concerned with the relation between consciousness and world, the perceiver and the perceived. This dissertation takes the investigation of the very “structure” or “pattern” of consciousness as its main purpose. LÄS MER

  5. 4. Optimization of confluent jets ventilation with variable airflow

    Författare :Harald Andersson; Mathias Cehlin; Roland Gårdhagen; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Confluent jets; Air distribution system; Air supply device; Ventilation performance; Indoor air quality; Thermal comfort; Experimental study; Computational fluid dynamics CFD ; Variable air volume.; confluent jets; luftdistributionssystem; tilluftsdon; ventilationsprestanda; inomhusluftkvalitet; termisk komfort; experimentell studie; Computational fluid dynamics CFD ; variabelflödessystem; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : In recent years, applications of confluent jets for design of ventilation supply devices have been widely studied. Similarly, numerous studies have been made on the potential and application of variable air volume (VAV) in order to reduce the energy demand of ventilation systems. LÄS MER

  7. 5. Interacting Magnetic Nanosystems : An Experimental Study Of Superspin Glasses

    Författare :Mikael Svante Andersson; Roland Mathieu; Dino Fiorani; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spin glass; SQUID magnetometry; maghemite; magnetism; nanoparticles;

    Sammanfattning : This thesis presents experimental results on strongly interacting γ-Fe2O3 magnetic nanoparticles and their collective properties. The main findings are that very dense randomly packed (≈60%) γ-Fe2O3 nanoparticles form a replica of a spin glass. LÄS MER
