    Sammanfattning : Primary Sjögren’s syndrome (pSS) is an autoimmune disease, primarliy affecting women, characterised by inflammation and destruction of exocrine glands with a prevalence of 0.01-0.09%. About one-third of the patients also suffer from extraglandular manifestations e. LÄS MER

  2. 2. Colour Vision in Birds : Comparing behavioural thresholds and model predictions

    Författare :Peter Olsson; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gallus gallus; receptor noise; visual modelling; animal training; colour discrimination; colour constancy;

    Sammanfattning : Birds use colour vision for many biologically relevant behaviours such as foraging and mate choice. Bird colour vision is mediated by four types of single cones, giving them an extra dimension of colour information compared to trichromatic humans. LÄS MER

  4. 4. Influence of ice-cover on local scour at circular bridge piers : an experimental study

    Författare :Peter Olsson; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : The objective of this work has been to investigate the effect of a simulated ice cover on the local scour depth around a cylindrical pier. Experiments were performed in a laboratory flume for different flow velocities with both a smooth and rough cover. The bed material consisted of uniform ripple-forming sand. LÄS MER

  5. 5. Molecular and Metabolic Aspects of Plant and Bacterial Salt Tolerance
