    Författare :Bengt-Olof Nilsson; Jan Ernerudh; Anders Wikby; Sture Löfgren; Karlis Pauksens; Linköpings universitet; []
    Nyckelord :Elderly; selection; health status; lymphocyte subsets; CD8; CMV; cytomegalovirus; immune risk; immune risk phenotype; IRP; T-cells; interleukin 6; IL-6; survival; mortality; antinuclear antibodies; ANA; ageing; immunosenescence; MEDICINE; MEDICIN;

    Sammanfattning : The oldest-old (people aged 80 or older) constituted 5 % of the population in Sweden in 2000, an increase from 1.5 % fifty years earlier. The immune system undergoes dramatic changes at high age, sometimes referred to as “immunosenescence”. LÄS MER

  3. 2. Biomolecular Aspects of Flexor Tendon Healing

    Författare :Maria Berglund; Monica Wiig; Olof Nilsson; Jan Fridén; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Flexor tendon healing; Growth factor; Metalloproteinase; Collagen; Proteoglycan; Myofibroblast; Hyaluronan synthase; Mast cell; Hand surgery; Handkirurgi; Orthopaedics; Ortopedi;

    Sammanfattning : Flexor tendon injuries in zone II of the hand (i.e. between the distal volar crease and the distal interphalangeal joint) can be costly for both the afflicted individual and society because of the high cost of a long rehabilitation period, complicated by tendon ruptures or scarring with adhesion formation, causing impaired range of motion.

  4. 3. Fracture toughness properties of duplex stainless steels

    Författare :Henrik Sieurin; Rolf Sandström; Jan-Olof Nilsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; duplex stainless steel; fracture toughness; austenite reformation; sigma phase; material optimisation; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Good toughness properties in base and weld material enable the use of duplex stainless steels (DSS) in critical applications. DSS offer high strength compared to common austenitic stainless steels. LÄS MER

  5. 4. Internal Control : A Study of the Concept and Themes of Internal Control

    Författare :Olof Arwinge; Fredrik Nilsson; Nils-Göran Olve; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP; Economic Information Systems; Ekonomiska informationssystem;

    Sammanfattning : This thesis studies the accounting and auditing approach to control where the concept of internal control has developed along with the theory and practice of accounting and auditing and its stated objectives. In this context, internal control has traditionally been regarded as a means of ensuring financial reporting quality as well as a way of preventing and detecting fraudulent activity. LÄS MER

  7. 5. Norway spruce heartwood : properties related to outdoor use

    Författare :Karin Sandberg; Lars-Olof Nilsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Sammanfattning : Degradation of wood is a complex problem dependent on many parameters, but especially the presence of excessive amounts of water causes many problems.The objective of this work was to study the influence of various parameters on water absorption and desorption in Norway spruce (Picea abies (L.) Karst). LÄS MER
