Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces This study explores methods to quantify and evaluate error in digital elevation models (DEMs) built from remotely sensed elevation data of the Hintereisferner glacier. A special focus lies on glacier surfaces because glaciers are often inaccessible for field observations but at the same time prone to m
The work as a social worker comes with a great responsibility when it comes to making decisions that may impact people's lives. The social worker has the opportunity to make a professional decision by using the information that has been provided from the clients. However, the social worker does not have the ability to make any decision based on their own preferences. They have the freedom of a
Adaptive phenotypic plasticity may improve the response of individuals when faced with new environmental conditions. Typically, empirical evidence for plasticity is based on phenotypic reaction norms obtained in reciprocal transplant experiments. In such experiments, individuals from their native environment are transplanted into a different environment, and a number of trait values, potentially i
Brottsoffer är ett ord med många konnotationer som har kritiserats för att antyda hjälplöshet och passivitet. Att kategoriseras som brottsoffer är inte alltid välkommet, men medför likväl fördelar, som till exempel möjligheten att driva en rättsprocess och tillgång till stöd och empati. I Sverige är Riksorganisationen Brottsofferjouren Sverige (BOJ) en viktig aktör när det gäller att ge brottsoffeCrime victim is a term with many connotations, which has been criticized for implying passivity and helplessness. To be categorized as a crime victim is not always welcomed. Still, being able to claim status as a victim is also connected to gains, in terms of both financial compensation and emotional support and compassion. In Sweden, Victim Support Sweden is an important actor in supplying help a
Aim Vegetation dynamics and the competitive interactions involved are assumed to restrict the ability of species to migrate. But in most migration modelling approaches disturbance-driven succession and competition processes are reduced to simple assumptions or are even missing. The aim of this study was to test a combination of a migration model and a dynamic vegetation model to estimate the migra
Subject-specific finite element models have been proposed as a tool to improve fracture risk assessment in individuals. A thorough laboratory validation against experimental data is required before introducing such models in clinical practice. Results from digital image correlation can provide full-field strain distribution over the specimen surface during in vitro test, instead of at a few pre-de
Objective. Cystectomy combined with pelvic lymph-node dissection and urinary diversion entails high morbidity and mortality. Improvements are needed, and a first step is to collect information on the current situation. In 2011, this group took the initiative to start a population-based database in Sweden (population 9.5 million in 2011) with prospective registration of patients and complications u
A study of the performance of five commercial radiotherapy treatment planning systems ( TPSs) for common treatment sites regarding their ability to model heterogeneities and scattered photons has been performed. The comparison was based on CT information for prostate, head and neck, breast and lung cancer cases. The TPSs were installed locally at different institutions and commissioned for clinica
Popular Abstract in Swedish Akut pankreatit (bukspottkörtelinflammation) drabbar årligen cirka 300 individer per miljon invånare i Sverige. Dödligheten ligger totalt på cirka 4-7 % och betydligt högre, cirka 20 %, vid svår nekrotiserande pankreatit. Mortaliteten är vanligen associerad med multipel organsvikt och korrelerad till storleken på det inflammatoriska svaret. Underliggande mekanismer för Acute pancreatitis (AP) is a common disorder where underlying mechanisms for the local initiating events in the pancreas, the systemic dissemination of the inflammatory response and the remote organ dysfunction still are unclear. The aim of the present study was to further characterize the dynamics and sequence of the immune response in AP, and to determine the cellular origin of the initiating ev
The spread of cancer cells to regional lymph nodes through the lymphatic system is the first step in the dissemination of breast cancer. In several human cancers including those of the breast and prostate, the expression of vascular endothelial growth factor C (VEGF-C) is associated with lymph node metastasis. Our study was undertaken to evaluate the effect of VEGF-C on metastasis of poorly invasi
For a short-lived organism, such as a freshwater zooplankter, the ways of coping with years of local recruitment failure are either to disperse between habitats and recolonise or to disperse in time through diapause. Diapause is common among freshwater zooplankton and is generally seen as a way to escape periods of harsh environmental conditions. The egg-bank or pool of diapausing copepodites in l
This article assesses the potential and the limitations of Thailand's proposed policy which would have local governments buy back targeted waste electronic and electrical equipment (WEEE) from households at designated locations. The proposal relies on the premise that a monetary incentive at the time of disposal is needed to gain participation from households which would otherwise sell to private
BACKGROUND: Sexual conflict theory predicts sexually antagonistic coevolution of reproductive traits driven by conflicting evolutionary interests of two reproducing individuals. Most studies of the evolutionary consequences of sexual conflicts have, however, to date collectively investigated only a few species. In this study we used the annual herb Collinsia heterophylla to experimentally test the
Background: Research involving expressed sequence tags ( ESTs) is intricately coupled to the existence of large, well-annotated sequence repositories. Comparatively complete and satisfactory annotated public sequence libraries are, however, available only for a limited range of organisms, rendering the absence of sequences and gene structure information a tangible problem for those working with ta
This report is the thesis of the research and development project entitled: Development of a Resource Saving Concept for the Establishment of a Climate Suitable for the Storage of Objects Worthy of Preservation in Storerooms at Museums and in Archives. In short: The ZEPHYR project. This work is the result of a research and development project. The aim is to improve the possibilities of using pass
Popular Abstract in Swedish Under det senaste decenniet har föräldrars intresse att välja fristående skolor för sina barn ökat markant. Läsåret 1998-99 gick, enligt Skolverket (1999), drygt 30 000 eller 3 % av grundskolans elever i fristående skolor. Det är emellertid en stor variation mellan landets kommuner. Trots den ringa andel som eleverna i fristående skolor utgör, har diskussionen om skolorAbstract Although the number of children attending private schools in Sweden is less than 4% of those attending compulsory schools, the debate of these schools has been intense. Apart from details as fees and funding, the role of education’ in the Swedish welfare system has been subject of much debate. In spite of the debate, in Sweden there is a lack of knowledge about private schools. The aim of
Popular Abstract in Swedish Bakgrunden till den här avhandlingen är att man vill utveckla en ny mammografimetod, som utnyttjar ultraljud. När en tunn stråle av kontinuerligt ultraljud träffar en partikel, till exempel en blodkropp, som rör sig, så uppstår en reflektion. Frekvensen av den reflekterade signalen är inte densamma som för den utsända. Signalen har fått ett så kallat Dopplerskift, där fThe motivation to study the kind of problems appearing in this thesis has been ultrasound measurements of flows, from which velocity spectra along lines can be determined. These velocity spectra can mathematically be described by a new non-linear transform, here called the Doppler Spectral Transform (DST). The Doppler spectral transform has a very rich theory, into which some steps are taken here
Popular Abstract in Swedish Biotisk och abiotisk stress hos mikroorganismer och växter.Various forms of stress, such as biotic and abiotic stress, were studied in microorganisms and plants to learn more about the underlying mechanisms of such stress and potential genetic engineering strategies towards stress tolerance. An antifreeze protein from winter flounder, expressed in E. coli, was subjected to directed evolution with NaCl as selective pressure. The resulting clones were teste
