BACKGROUND: The association of early knee joint laxity with the need for later reconstruction of the anterior cruciate ligament has not been extensively studied. HYPOTHESIS: The grade of knee laxity can be used as an early predictor of the need for later reconstruction. STUDY DESIGN: Cohort study (prognosis); Level of evidence, 2. METHODS: One hundred consecutive patients with an acute arthroscopi

AIMS: To analyse whether gestational diabetes mellitus (GDM) was associated with increases in healthcare utilisation after delivery. METHODS: A longitudinal case-control registry-based study of 579 women with GDM delivered in 1995-2001. Two controls for each case were selected from the Swedish National Board of Health and Welfare, matched for year of birth, year of delivery, and municipality of r

Abstract in UndeterminedThe attractiveness of places is currently gaining a high policy salience in policymakers’ efforts to draw mobile capital. Yet, while there are a growing number of empirical studies considering the migration of people and the attractiveness of places, there is an acute lack of conceptual understanding of the phenomena that hamper discussions between researchers and policymak

Optimal data detection of a linear channel can always be implemented through the Viterbi algorithm (VA). However, in many cases of interest the memory of the channel prohibits application of the VA. A popular and conceptually simple method in this case, studied since the early 70s, is to first filter the received signal in order to shorten the memory of the channel, and then to apply a VA that ope

The purpose of the current work is the comparison of a phenomenological and a laminate-based model for rate-dependent switching in ferroelectric single crystals. To this end, the phenomenological model formulation of [1] is considered. In this model, the polarization vector is treated as an internal variable. The evolution of the polarization determines the remanent strain; dependence of energy st

Nurses in Sweden have a high absence due to illness and many retire before the age of sixty. Factors at work as well as in private life may contribute to health problems. To maintain a healthy work-force there is a need for actions on work-life balance in a salutogenic perspective. The aim of this study was to explore perceptions of resources in everyday life to balance work and private life among

Chemokine (C-C motif) receptor 2 (CCR2)-signaling can mediate accumulation of microglia at sites affected by neuroinflammation. CCR2 and its main ligand CCL2 (MCP-1) might also be involved in the altered metabolism of beta-amyloid (Aβ) underlying Alzheimer's disease (AD). We therefore measured the levels of CCL2 and three other CCR2 ligands, i.e. CCL11 (eotaxin), CCL13 (MCP-4) and CCL26 (eotaxin-3

We develop a general patch-use model of central place foraging, which subsumes and extends several previous models. The model produces a catalog of central place effects predicting how distance from a central place influences the costs and benefits of foraging, load-size, quitting harvest rates, and giving-up densities. In the model, we separate between costs that are load-size dependent, i.e. a d

In this thesis, computationally efficient statistical models for large spatial environmental data sets are constructed. In the first part of the thesis, a method for estimating spatially dependent temporal trends is developed. A space-varying regression model, where the regression coefficients for the spatial locations are dependent, is used. The spatial dependence structure is specified by a Ga

Participants decided whom of two patients to prioritize for surgery in three studies. The factual quantitative information about the patients (e.g., probability of surviving surgery) was given in vignette form with case descriptions on Visual Analogue Scales - VAS's. Differentiation and Consolidation theory predicts that not only the attractiveness of facts but also the mental representations of o

This article is about the cognitive meanings of animal ornamentation in a long term perspective. Special focus is upon the relation between the images of animal ornamentation and verbal expressions in the heroic skaldic poetry from the early medieval period. The article also discuss animal ornamentation in relation to gender.

This paper presents the results of combined investigation of the chemical bond formation in fluorinated multiwalled carbon nanotubes (MWCNTs) with different fluorine contents (10-55 wt %) and reference compounds (highly oriented pyrolytic graphite crystals and "white" graphite fluoride) using x-ray absorption and photoelectron spectroscopy at C 1s and F 1s thresholds. Measurements were performed a

Vertical arrays of direct band gap III-V semiconductor nanowires (NWs) hold the prospect of cheap and efficient next-generation photovoltaics, and guidelines for successful light-management are needed. Here, we use InP NWs as a model system and find, through electrodynamic modeling, general design principles for efficient absorption of sun light in nanowire arrays by systematically varying the nan

Many control engineering tasks nowadays rely on the simulation of complex multi-physics systems. Modern tools allow to build the required dynamic models conveniently, thanks to Object-Oriented Modelling languages, e.g., Modelica, and to perform simulations with hardly any additional effort on the part of the analyst. However, when simulation speed is of concern, the same tools fall short of exploi

Popular Abstract in Swedish Hjärt- och kärlsjukdomar är den främsta orsaken till en för tidig död för både män och kvinnor i dagens industrialiserade samhällen. I det akuta förloppet av dessa sjukdomar spelar blodplätten (trombocyten) en viktig roll då den är inblandad i bildandet av blodproppar. Den kärnlösa och kortlivade trombocytens roll är vanligen en annan och central i läkningsprosessen av Platelets are central for the primary haemostatis. The platelet has surface bound receptors that are vital for the platelet activation. One of these receptors, the purinergic ADP-activated G-protein coupled receptor (GPCR) P2Y12 is a key receptor for platelet activation, and thus for thrombus formation, which makes P2Y12 a target in pharmaceutical antiplatelet therapies. As a complement during rev
