Altered movement patterns and deviating muscular activity in individuals with anterior cruciate ligament injury
Popular Abstract in Swedish Skador i knäleden är vanligt förekommande och främre korsbandsskada drabbar i Sverige årligen mer än 8 per 10 000 personer i åldern 10-64 år. Följderna av skadan kan bli bestående funktionsnedsättning med bl.a. instabilitet, plötsliga och smärtsamma knäledsvikningar och ökad risk för nya skador. Cirka hälften av patienterna utvecklar ledsvikt (artros) 10-15 år efter denThe purpose of this thesis was to increase the understanding of altered movement patterns in individuals with anterior cruciate ligament (ACL) injury in order to improve ACL rehabilitation, and to develop an observational instrument termed Test for Substitution Patterns (TSP) for standardized, quantifiable scoring of altered movement patterns in legs and trunk. In all, 142 participants, 93 with A
Searches for heavy long-lived sleptons and R-hadrons with the ATLAS detector in pp collisions at root s=7 TeV
A search for long-lived particles is performed using a data sample of 4.7 fb(-1) from proton-proton collisions at a centre-of-mass energy. root s = 7 TeV collected by the ATLAS detector at the LHC. No excess is observed above the estimated background and lower limits, at 95% confidence level, are set on the mass of the long-lived particles in different scenarios, based on their possible interactio
A "wait and learn" strategy of postural control learning in children?
This study compares the children and adult response to a novel postural challenge. One group of children (n = 13, age 7-9) and one adult reference group (n = 12 age 15-32) were subjected to vibration induced body sway and posturography with both open and closed eyes for 5 consecutive days. There was a gradual decrease of induced body sway over time in both groups (p < 0.001) between the subsequent

Development of a system for determination of the C-13/C-12 isotopic ratio with high spatial resolution
Stable carbon isotopes play an important role in the interpretation of biological activity, particularly when the fossil record is studied. In combination with morphological and chemical data, isotopic information can be useful in paleontology and astrobiology. In this paper the development of a microanalytical ion beam system for the measurement of the carbon isotope ratio with high spatial resol

Analysis-by-synthesis speech coding with quantization noise modeling
Iii analysis-by-synthesis linear predictive coding (AbS-LPC) an LPC synthesis filter is combined with an analysis-by-synthesis search of the excitation signal. The synthesis filter is an estimator for the speech signal given the excitation. However in most AbS-LPC algorithms this estimator has no explicit model of the quantization noise, which is present in the excitation signal. This paper descri
Chips on wafers, or packing rectangles into grids
A set of rectangles S is said to be gridpacked if there exists a rectangular grid (not necessarily regular) such that every rectangle lies in the grid and there is at most one rectangle of S in each cell. The area of a grid packing is the area of a minimal bounding box that contains all the rectangles in the grid packing. We present an approximation algorithm that given a set S of rectangles and a

Lipid-Block Copolymer-Immiscibility
We have investigated the binary system of a triblock copolymer of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO), EO5PO68EO5, in water. The ternary system with the same polymer, water and soybean phosphatidylcholine (lecithin) has also been studied. Small-angle X-ray scattering (SAXS), 2H NMR and differential scanning calorimetry (DSC) were used to characterize these systems. The phase

Mechanisms for Targeting of Proteins to Secretory Lysosomes of Haematopoietic Cells
Popular Abstract in Swedish Kroppens immunförsvar, vars uppgift är att skydda oss mot infektioner, består av ett antal olika celltyper som till stor del finns i blodet. Immunförsvaret kan indelas i två delar; ett medfött försvar som är likadant hos alla individer och ett försvar som byggs upp under individens livstid. Det senare utformas olika beroende på vilka bakterier och virus som individen utThe cells of the innate immune system are essential for the host's first line defence against infection. Among these cells the neutrophil granulocyte has a central role by the production of antibiotic proteins and peptides. These are targeted for storage in secretory lysosomes and other neutrophil granules for subsequent release by regulated secretion in an inflammatory process. However, the granu
Induction of myocarditis in rabbits injected with group A streptococci
Background & objectives: We have earlier proposed that group A streptococcal (GAS) immunoglobulin binding surface proteins (IgGBPs) might trigger anti-IgG production and immune complex formation leading to glomerulonephritis. In the present study, cardiac tissue material from rabbits injected with heat-killed GAS was investigated. Methods: Rabbits were injected intravenously with 10(9) colony
Invading herbivory: The golden apple snail alters ecosystem functioning in Asian wetlands
We investigated the effects of an exotic snail, the golden apple snail (Pomacea canaliculata) on biodiversity and ecosystem functioning in tropical wetland ecosystems. This large snail (up to 80-mm shell height) has invaded large parts of Southeast Asia during recent decades. A survey of natural wetlands in Thailand showed that high densities of the snail were associated with almost complete absen
Uniform semiclassical trace formula for U(3) -> SO(3) symmetry breaking
We develop a uniform semiclassical trace formula for the density of states of a three-dimensional isotropic harmonic oscillator (HO), perturbed by a term 1/4 epsilon r(4). This term breaks the U(3) symmetry of the HO, resulting in a spherical system with SO(3) symmetry. We first treat the anharmonic term for small e in semiclassical perturbation theory by integration of the action of the perturbed
Effect of inhaled fluticasone with and without salmeterol on airway inflammation in asthma
Background: The clinical benefit of combining long-acting beta(2)-agonists with inhaled corticosteroids rather than doubling the dose of corticosteroid has been well-documented. However, there are concerns that this might result in a masking of underlying airway inflammation. Objective: The aim of this study was to test the hypothesis that the addition of the long-acting beta(2)-agonist salmeterol
Optimized density gradient separation of leukocyte fractions from whole blood by adjustment of osmolarity
Some of the compounds used for density gradient separation of blood cells have high osmolarities at the concentrations needed to create the required specific densities. Several mixed media use a combination of hyperosmolar shrinkage and red cell aggregation to improve cell separation. Due to the characteristics of Percoll density gradient medium the density and osmolarity of the gradient can be co
