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

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
I tidigare forskning om krig presenteras ofta ensidiga bilder av fenomenen krigsvåld, offerskap och försoning. Denna bok utgår från berättelser av överlevande efter kriget i Bosnien under 1990-talet. Syftet är att analysera hur de intervjuade beskriver dessa fenomen samt vilka diskursiva mönster som framträder i konstruktionen av begreppen ”offer” och ”förövare”. Mina frågeställningar är: Hur beskThis book analyzes verbally depicted experiences of survivors from the war in Bosnia and Herzegovina. One purpose to describe how the actors portray the social phenomenon of “war violence” “victimhood” and “reconciliation”, and the second aim is to analyze discursive patterns that emerges in the creation of the terms “victim” and “perpetrator”. My research questions are: (1) How do the interviewee
New evidence is emerging that semi-arid ecosystems dominate interannual variability (IAV) of the global carbon cycle, largely via fluctuating water availability associated with El Niño/Southern Oscillation. Recent evidence from global terrestrial biosphere modelling and satellite-based inversion of atmospheric CO2 point to a large role of Australian ecosystems in global carbon cycle variability, i
A significant portion of the large amount of carbon (C) currently stored in soils of the permafrost region in the Northern Hemisphere has the potential to be emitted as the greenhouse gases CO2 and CH4 under a warmer climate. In this study we evaluated the variability in the sensitivity of permafrost and C in recent decades among land surface model simulations over the permafrost region between 19
Primary productivity of terrestrial vegetation is expected to increase under the influence of increasing atmospheric carbon dioxide concentrations ([CO2]). Depending on the fate of such additionally fixed carbon, this could lead to an increase in terrestrial carbon storage, and thus a net terrestrial sink of atmospheric carbon. Such a mechanism is generally believed to be the primary global driver
Africa has been undergoing significant changes in climate and vegetation in recent decades, and continued changes may be expected over this century. Vegetation cover and composition impose important influences on the regional climate in Africa. Climate-driven changes in vegetation structure and the distribution of forests versus savannah and grassland may feed back to climate via shifts in the sur
The savanna ecosystem is one of the most dominant and complex terrestrial biomes, deriving from a distinct vegetative surface comprised of co-dominant tree and grass populations. While these two vegetation types co-exist functionally, demographically they are not static but are dynamically changing in response to environmental forces such as annual fire events and rainfall variability. Modelling s
A realistic simulation of snow cover and its thermal properties are important for accurate modelling of permafrost. We analyse simulated relationships between air and near-surface (20 cm) soil temperatures in the Northern Hemisphere permafrost region during winter, with a particular focus on snow insulation effects in nine land surface models, and compare them with observations from 268 Russian st
Most existing traffic conflict indicators do not sufficiently take into account the severity of the injuries resulting from a collision had it occurred. Thus far, most of the indicators that have been developed express the severity of a traffic encounter as their proximity to a collision in terms of time or space.This paper presents the theoretical framework and the first implementation of Extende
This article focuses on coordination between governance actors in a public university. The purpose of this paper is to illustrate and analyze policy documents as governance tools that allow departmental management to coordinate with the authorities, the board, and the management at different university levels. A central finding is that the importance of policy documents as governance tools takes e
Denna avhandling behandlar två essentiella ting, vatten som är grundläggande för allt liv på jorden och kväve, vilket är ett grundämne som återfinns i varje protein och DNA. Liksom allt annat, måste dessa ämnen hålla en lagom nivå i cellen. För att klara variationer i tillgänglighet av dessa ämnen, har alla livsformer hittat sätt att påverka upptag och frisättning av dem. För att realisera detta pMajor intrinsic proteins, also referred to as aquaporins (AQPs) are localized in membranes of all domains of life to increase the permeability to water or other small, polar molecules. Several monophyletic groups can be discerned in this large and divergent protein superfamily. Members within these subfamilies commonly show a similar substrate selectivity established by conserved filters. Comparis
