  1. 16. 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.

  3. 17. Thermal stability and mechanical properties of TiAlN-based multilayer and monolithic coatings

    Författare :Axel Knutsson; Magnus Odén; Lennart Karlsson; Grégory Abadias; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis explores the thermal stability, microstructure, mechanical properties and cutting performance of multilayer and monolithic cubic TiAlN hard coatings. The aim is to increase the understanding of how the coatings’ microstructure and properties are affected by a layered structure when exposed to high temperatures. LÄS MER

  4. 18. Development and comparison of in vitro toxicity methods for nanoparticles : Focus on lung cell exposure

    Författare :Siiri Latvala; Karine Elihn; Hanna Karlsson; Lennart Möller; Hannu Norppa; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Concerns for the toxic effects of airborne nanoparticles have been raised along with the increasing production of nanostructured materials. However, the health risks of nanoparticle exposure are currently not fully understood. The most commonly used techniques to study nanoparticle toxicity, both in vivo and in vitro, have several limitations. LÄS MER

  5. 19. Att fördela bistånd : Om handläggningsprocessen inom äldreomsorgen

    Författare :Margareta Lindelöf; Eva Rönnbäck; Lennart Nygren; Urban Karlsson; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social service; Socialt arbete; Äldreomsorg; Socialtjänstlag; Handläggning; Behovsbedömning; Rättssäkerhet; Gräsrotsbyråkrat; Handlingsutrymme; Social work; Socialt arbete;

    Sammanfattning : The aim of this dissertation is to illustrate the manner in which assistance is distributed to the elderly according to the social services law in Sweden. It will focus on the processing officers/"street-level bureaucrats" who have been assigned, based on their profession, the task of assessing and deciding about the distributing of assistance.

  7. 20. PET and MR imaging in prostate cancer

    Författare :Kristina Sandgren; Tufve Nyholm; Joakim Jonsson; Camilla Thellenberg-Karlsson; Lennart Blomqvist; Heidi Lyng; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET; PSMA; MRI; PET MRI; imaging; prostate cancer; intraprostatic tumour detection; radiofysik; radiation physics;

    Sammanfattning : The current risk assessment of prostate cancer (PC) relies on histopathological samples from biopsies and clinical variables such as prostate-specific antigen (PSA). However, this comes with uncertainties and in some cases it can be challenging to separate patients who would benefit from radical treatment and those who would not. LÄS MER
