Morphology as a key to behavioural flexibility: body shape and swimming variability in the dimorphic crucian carp

Swimming trajectories of length-matched deep-bodied and shallow-bodied crucian carp were quantified in the laboratory using motion analysis software and compared in terms of swimming velocity, turning behaviour and associated coefficients of variation. The mean velocities of the two morphs were similar, but slower than predicted, and there was no difference in turning behaviour. In line with predi

Continental-scale patterns of nutrient and fish effects on shallow lakes: introduction to a pan-European mesocosm experiment

1. Shallow lake ecosystems are normally dominated by submerged and emergent plants. Biological stabilising mechanisms help preserve this dominance. The systems may switch to dominance by phytoplankton, however, with loss of submerged plants. This process usually takes place against a background of increasing nutrient loadings but also requires additional switch mechanisms, which damage the plants

Integral equation methods and numerical solutions of crack and inclusion problems in planar elastostatics

We present algorithms for crack and inclusion problems in planar linear elastostatics. The algorithms are based on new integral equations. For the pure crack problem the integral equations are of Fredholm's second kind. Our algorithms show great stability and allow for solutions to problems more complex than have previously been possible. Our results are orders of magnitudes more accurate than tho

Increased prevalence of seropositivity for non-gastric Helicobacter species in patients with autoimmune liver disease

Various Helicobacter species have been isolated from the stomach, intestinal tract and liver of a variety of mammalian and some avian species, and Helicobacter DNA has been detected in human bile and liver samples. An immunoblot assay was established to analyse serum antibody responses to non-gastric Helicobacter species in patients with autoimmune liver diseases, in comparison with healthy indivi

DEAF SIGN LANGUAGE USERS - Prevalence and Aspects of Quality of Life in Old Age

Popular Abstract in Swedish Under de senaste åren har nödvändigheten att ta hänsyn till utsatta grupper i den svenska befolkningen och deras varierande behov lyfts fram i rapporter och utredningar om utformningen av vård och rehabilitering av äldre. En sådan utsatt grupp är äldre teckenspråkliga döva. Svårigheten att kommunicera, i kombination med åldersrelaterade sjukdomar, funktionsbegränsningarVery little is known about the consequences of aging and the wellbeing of deaf sign language users. This thesis contributes to filling this knowledge gap. The overarching aim was to gain further understanding and to increase the knowledge about quality of life, in terms of subjective wellbeing and health, activity and social contacts, among older deaf sign language users. After having established

A VLSI architecture of the square root algorithm for V-BLAST detection

MIMO has been proposed as an extension to 3G and Wireless LANs. As an implementation scheme of MIMO systems, V-BLAST is suitable for the applications with very high data rates. The square root algorithm for V-BLAST detection is attractive to hardware implementations due to its low computational complexity and numerical stability. In this paper, the fixed-point implementation of the square root alg

Aging studies for the ATLAS Transition Radiation Tracker (TRT)

A summary of the aging and material validation studies carried out for the ATLAS Transition Radiation Tracker (TRT) is presented. Particular emphasis is put on the different phenomena observed in straw tubes operating with the chosen Xe/CF4/CO2 mixture. The most serious effects observed are silicon deposition on the anode wire and damage of the anode wire gold plating. Etching phenomena and active

Dualities, affine vertex operator algebras, and geometry of complex polynomials

This thesis consists of two parts which deal with different subjects. In the first part we study certain aspects of the representation theory of affine Kac-Moody Lie algebras and related structures. We notice that for any positive integer k, the set of (1,2)-specialized characters of the level k standard A11-modules is the same as the set of rescaled graded dimensions of the subspaces of the level

On modelling of thermal radiation properties for biofuels

Simple and computer attractive models for calculating radiation properties are needed. This paper considers recent models available in literature, and provides suggestions how to improve the calculation performance of the existing ones.

Putskvalitet : inverkan av olika faktorer

Rapporten redovisar hur olika faktorer påverkar putsens egenskaper. De faktorer som undersökts är bindemedelstyp, underlagets vattensugning, härdningsklimat och -tid. De egenskaper hos putsen som studerats är karbonatiseringsgrad, e-modul, hållfasthet samt vittringsbeständighet.

Adaptation and resiliency in Swedish families

A longitudinal research project began in 1993 of Norwegian, Swedish and American mothers' perception of her family's dynamics and adaptation during childbearing and childrearing. Results indicated that Swedish mothers adapted better than other mothers. In 2003, a mixed design study was conducted with original Swedish mothers that aimed to describe the experience of motherhood, the meaning mothers

Vaginal microbiological flora, and behavioural and clinical findings in women with vulvar pain

OBJECTIVE: To study genital symptoms and signs in women with vulvar pain, and the association with potential risk factors such as microbiological agents, sexual behaviour and genital hygiene. DESIGN: Prospective cohort study of apparently healthy women attending for contraceptive advice. SETTING: Two family planning clinics and one youth clinic in Sweden. POPULATION: Out of 996 women recruited, 79
