Periodic orbits of 3-d dynamical systems admitting a Poincaré section can be described as braids. This characterisation can be transported to the Poincaré section and Poincaré map, resulting in the braid type. Information from braid types allows to estimate bounds for the topological entropy of the map while revealing detailed orbit information from the original system, such as the orbits tha
Popular Abstract in Swedish Denna avhandling utforskar och analyserar segregation och självsortering i utbildning. Den syftar till att diskutera hur detta relateras till genus, individualisering och unga mäns och kvinnors positioneringar i lokala praktiker, genom val av gymnasieutbildning. Den fokuserar hur unga män och kvinnor hanterar och anpssar sig till det förändrade senmoderna samhället. AvThis thesis explores and analyzes segregation and self-sorting in education. It aims at discussing how this relates to gender, individualization and young men and women's positionings in local practices, through choices of upper secondary school education. It focuses on how young men and women cope with and adapt to the changing society in late modernity. The thesis is based on three empirical st
Popular Abstract in Swedish En bred, distinkt materialpresentation är knuten till enskilda variabler av psykologiskt märke. Dessa innebär ett sök efter den autentiske Garborg, värderat som såväl symptombärare som symptomlösare. Introduktionen till Garborgs levnadshistoria avser att vara en invitation, speciellt till dem som inte är bekanta med honom som person och författare. Utifrån en period kriA broad, distinctive material presentation is done, which is linked to some variables of psychological value, stating a research for the authenticity of Garborg in viewing him as well a symptom bearer as a symptom solver. An introduction to Garborg is meant to be an invitation, especially to those who are not so well acquainted with him as a person and a writer. Out from a period of about 110 year
Frogs are often rare or absent from intensively farmed areas. Here we explore the possibility that the landscape and the quality of the terrestrial habitat are unsuitable for these populations. Spawn of Rana arvalis and R. temporaria was introduced into ponds in a south Swedish agricultural landscape in 2003 (eight ponds) and 2004 (ten ponds). Metamorphs emerged from nine (R. a.) and 12 (R. t.) of
To be able to connect wirelessly to the internet is nowadays a part of everyday life and the number of wireless devices accessing wireless networks worldwide are increasing rapidly. However, with the increasing number of wireless devices and applications and the amount available bandwidth, spectrum shortage is an issue. A promising way to increase the amount of available spectrum is to utilize fre
Global environmental change and increasing human population emphasize the urgent need for higher yielding and better adapted crop plants. One strategy to achieve this aim is to exploit the wealth of so called landraces of crop species, representing diverse traditional domesticated populations of locally adapted genotypes. In this study, we investigated a comprehensive set of 1485 spring barley lan
Popular Abstract in Swedish Tre-dimensionell ultraljudsundersökning av livmodertappen (cervix) Syftet med avhandlingen var att utvärdera förändringar i livmodertappen (cervix) med tre-dimensionellt ultraljud och utreda om tre-dimensionellt power Doppler ultraljud kan förutsäga tiden till spontan eller inducerad förlossning hos överburna, gravida kvinnor. Avhandlingen baseras på fem studier: reprThe aim of this thesis was to evaluate cervical physiological changes by three-dimensional (3D) ultrasound during pregnancy and to investigate the ability of 3D power Doppler to predict time to spontaneous and induced delivery in prolonged pregnancy. The thesis is based on five studies: reproducibility of cervical measurements by 3D power Doppler ultrasound (study I), reference data representativ
In 1995 and 1996 a Swedish feed mill had problems due to a persistent contamination of Salmonella enterica spp. enterica serovar Senftenberg that was difficult to eliminate. Forty-eight strains isolated from the feed mill, together with unrelated strains included to evaluate the discriminatory power and reproducibility, were analysed by pulsed-field gel electrophoresis (PFGE). The source of contam
This article compares and contrasts male immigrant labor market experiences in Sweden and Denmark during the period 1985-1995. Using register-based panel data sets from Sweden and Denmark, a picture of the employment assimilation process of immigrants from Norway, Poland, and Turkey is presented. The comparative approach shows that immigrants in Sweden and Denmark experienced similar declines in e
Rationale & Objective: Chronic kidney disease (CKD) is complicated by abnormalities that reflect disruption in filtration, tubular, and endocrine functions of the kidney. Our aim was to explore the relationship of specific laboratory result abnormalities and hypertension with the estimated glomerular filtration rate (eGFR) and albuminuria CKD staging framework. Study Design: Cross-sectional in
Most proteins have evolved to function optimally in aqueous environments, and the interactions between protein and water therefore play a fundamental role in the stability, dynamics, and function of proteins. Although we understand many details of water, we understand much less about the protein-water interface. In this thesis we use molecular dynamics (MD) simulations to cast light on many struct
Electrical storm (ES) presents a difficult management problem that has predominantly been described in adults and there are limited published data relating to children. We set out to characterize ES in children to assist management based on published literature and own institutional experience. We retrospectively analyzed the records of children presenting with ES to our institution between July 2
BACKGROUND: Food choice decisions are complex processes influenced by various factors that affect the family's diet and, thus, their health and nutrition. In low- and middle-income countries like Ethiopia, these factors are shaped by the ongoing nutrition transition, urbanization, and socio-economic challenges. Despite growing concerns about the double burden of malnutrition, the factors influenci
