  1. 11. Haptic and visual simulation of material cutting process : a study focused on bone surgery and the use of simulators for education and training

    Författare :Magnus G. Eriksson; Jan Wikander; Ingela Nyström; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; surgical simulation; virtual reality; haptic feedback; surgical training; medical simulators; metrics; 3D visualization; Medical technology; Medicinsk teknik;

    Sammanfattning : A prototype of a haptic and virtual reality simulator has been developed for simulation of the bone milling and material removal process occurring in several operations, e.g. temporal bone surgery or dental milling. The milling phase of an operation is difficult, safety critical and very time consuming. LÄS MER

  4. 13. Fatigue and Peripheral Muscle Dysfunction: Studies on Vitamin D Status, Muscle Metabolism and Systemic Inflammation in Patients with COPD : Aspects of COPD severity beyond FEV1 and exacerbations

    Författare :Magnus Kentson; Lennart Persson; Jan-Erik Karlsson; Fredrik Nyström; Arne Egesten; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : BackgroundThe severity of Chronic Obstructive Pulmonary Disease (COPD) is usually described in terms of forced expiratory volume in one second (FEV1) and number of exacerbations. However, COPD is a complex disease with different ways of expression, involving pulmonary symptoms, extra pulmonal manifestations and comorbidities, which altogether affect the patient by contributing to reduced functional capacity, increased shortness of breath, reduced health-related quality of life and increased mortality.

  5. 14. Measurement of alignment between standards and assessment

    Författare :Gunilla Näsström; Widar Henriksson; Peter Nyström; Jan-Olof Lindström; Astrid Pettersson; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alignment; standards; assessment; Bloom s revised taxonomy; the Angoff method; the borderline-group method; usefulness; validity; Other processing assembly; Övrig bearbetning sammanfogning;

    Sammanfattning : Many educational systems of today are standards-based and aim at for alignment, i.e. consistency, among the components of the educational system: standards, teaching and assessment. To conclude whether the alignment is sufficiently high, analyses with a useful model are needed. LÄS MER

  7. 15. Transcriptional activity of PPARγ in primary human adipocytes

    Författare :Lilian Sauma; Fredrik Nyström; Mats Söderström; Jan Eriksson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The prevalence of obesity is increasing in most parts of the world and is a strong risk factor for the development of insulin resistance, type 2 diabetes and hypertension. Adipose tissue is mainly composed of adipocytes which store energy in the form of triglycerides and release it as free fatty acids. LÄS MER
