Elektroaktiva polymerers (EAPs) främsta egenskap är deras förmåga att kunna omvandla elektrisk energi till mekanisk energi (och vice versa). Den typ av EAPs som behandlas inom ramen för detta arbete kallas för dielektriska elastomerer och är en undergrupp av elektroniska elektroaktiva polymerer. De karakteriseras av en väldigt låg elastisk styvhet, kapabel till stora elastiska deformationer, och a
The cadastre of King Valdemar is one of the most investigated and debated written sources that survive from early medieval Denmark. In particular, the detailed list of revenue from Halland has attracted a lot of attention. Despite this, many unanswered questions still remain. This article attempts to address some of these queries.
Ultrafiltration and nanofiltration have become common methods to treat surface water for drinking water purposes. Common aims of a membrane step are removal of natural organic matter (NOM), softening or adding an extra microbiological or chemical barrier. In most cases, the membrane is considered a good disinfection step; commonly the viral removal is at least 4–log. To ensure a working disinfecti
The molecular details and impact of oligosaccharide uptake by distinct human gut microbiota (HGM) are currently not well understood. Non-digestible dietary galacto- and gluco-α-(1,6)-oligosaccharides from legumes and starch, respectively, are preferentially fermented by mainly bifidobacteria and lactobacilli in the human gut. Here we show that the solute binding protein (BlG16BP) associated with a
Screening studies of a population in primary health care are sparsely reported. The aim was to describe observed atypical behaviours that may be associated with autism spectrum conditions, in a population (n = 4329) of infants at eight months. Observations were performed by paediatric nurses. An observational instrument, named SEEK developed for child health care, was used focusing on social inter
Kalamang is Papuan language spoken by 150 people in the east of Indonesia. The language is threatened with extinction. This thesis treats mainly phonetics and phonology, but also gives an overview over parts of Kalamang grammar. Pronouns, demonstratives, nominal morphology and some basic syntax are discussed, among other things. The thesis also includes a word list with 700 Kalamang lexemes, and a

Objective Comparison of provider performance is commonly used to inform health care decision-making. Little attention has been paid to how data presentations influence decisions. This study analyzes differences in suggested actions by decision-makers informed by league tables or funnel plots.Design Decision-makers were invited to a survey and randomized to compare hospital performance using either
Here we investigate the feasibility of silver as seed-particle material to synthesize GaAs nanowires and show that both crystal phase and growth direction can be controlled by choice of substrate orientation. A (111)B substrate orientation can be used to form vertically aligned wurtzite GaAs nanowires and a (100) substrate orientation to form vertically aligned zinc blende GaAs nanowires. A 45-50%
Lymphangiogenesis plays a pivotal role in diverse pathological conditions. Here, we demonstrate that a carbohydrate-binding protein, galectin-8, promotes pathological lymphangiogenesis. Galectin-8 is markedly upregulated in inflamed human and mouse corneas, and galectin-8 inhibitors reduce inflammatory lymphangiogenesis. In the mouse model of corneal allogeneic transplantation, galectin-8-induced
In this work we include electron-electron interaction beyond Hartree-Fock level in our non-equilibrium Green's function approach by a crude form of GW through the Single Plasmon Pole Approximation. This is achieved by treating all conduction band electrons as a single effective band screening the Coulomb potential. We describe the corresponding self-energies in this scheme for a multi-subband syst
Skogsekosystemet är ett av de viktigaste ekosystemen på jorden. Skogen förser oss med mycket som vi har nytta av, vilket numera ofta kallas ekosystemtjänster. Skogen reglerar och förser oss med många viktiga ekosystemtjänster, till exempel biodiversitet, skydd av mark och vatten, tillförsel av fiber, bränsle och andra skogsprodukter, klimatreglering samt sociokulturella värden och tjänster. ArealeThe forest ecosystem provides and regulates many important ecosystem services, such as soil and water protection, timber production, and climate regulation. It has been influenced by changes induced by humans, for example, our increasing demand for timber and bioenergy, the increase in nitrogen (N) deposition and CO2 concentrations due to industrialization, and climate change which has caused an i
A large number of medical examinations involve images in some way. Images can be used for diagnostics, follow-up studies and treatment planning. In this thesis mathematical methods have been developed and adapted in order to analyze medical images. Several applications for different imaging modalities have been studied and the usefulness of such methods is demonstrated.A complete system for detect
Using non-equilibrium Green's functions combined with many-body perturbation theory, we have calculated steady-state densities and currents through short interacting chains subject to a finite electric bias. By using a steady-state reverse-engineering procedure, the effective potential and bias which reproduce such densities and currents in a non-interacting system have been determined. The role o
Historisk-demografisk forskning är central för att förstå mänskliga beteenden och egenskaper genom historien, såsom fertilitet, dödlighet och migration. En väsentlig del inom historisk demografi är att utföra longitudinella analyser på mikronivå. Detta innebär att individer följs kontinuerligt över livscykeln utifrån demografiska händelser (födelse, giftermål, flyttningar och död) under flera geneHistorical demographic research is central to understanding past human behaviours and traits, such as fertility, mortality and migration. An essential part of historical demography is conducting longitudinal analyses at the micro-level, which involves the detailed follow-up of individuals over long time periods throughout their lives. By including the geographic context in such analyses, we can st
