Using harmonic maps we provide an approach towards obtaining explicit solutions to the incompressible two-dimensional Euler equations. More precisely, the problem of finding all solutions which in Lagrangian variables (describing the particle paths of the flow) present a labelling by harmonic functions is reduced to solving an explicit nonlinear differential system in C-n with n = 3 or n = 4. Whil
Clotting systems are required in almost all animals to prevent loss of body fluids after injury. Here, we show that despite the risks associated with its systemic activation, clotting is a hitherto little appreciated branch of the immune system. We compared clotting of human blood and insect hemolymph to study the best-conserved component of clotting systems, namely the Drosophila enzyme transglut
Statin drugs have been used for more than two decades to treat hypercholesterolemia and as cardio-preventive drugs, resulting in a marked decrease in cardiovascular morbidity and mortality worldwide. Statins halt hepatic cholesterol biosynthesis by inhibiting the rate-limiting enzyme in the mevalonate pathway, hydroxymethylglutaryl-coenzyme A reductase (HMGCR). The mevalonate pathway regulates a h
The German federal state of North Rhine-Westphalia (NRW) is home to one of the most important industrial regions in Europe, and is the first German state to have adopted its own Climate Protection Law (CPL). This paper describes the long-term (up to 2050) mitigation scenarios for NRW's main energy-intensive industrial sub-sectors which served to support the implementation of the CPL. It also descr
In all over the world, there have been assessed two common energy and climate strategies. One relies on improving energy efficiency and the other aims to increase the market share of renewable energy. Turkey, being an important country in terms of energy and climate issues is required to integrate energy efficiency and renewable energy strategies into energy planning to better decide on energy sec
This thesis measures cost efficiency in the production of health care and social services in Sweden. The object of analysis is not provider efficiency, but instead the relative efficiency of political organizations or different contractual arrangements. The thesis focuses on: 1) the measurement of cost efficiency, 2) the investigation of potential trade-offs between quantity of health care service
BACKGROUND: Knee rotation plays an important part in knee kinematics during weight-bearing activities. An external device for measuring knee rotation (the Rottometer) has previously been evaluated for validity by simultaneous measurements of skeletal movements with Roentgen Stereometric Analysis (RSA). The aim of this study was to investigate the reliability of the device. METHOD: The within-day
Syftet med detta arbete är att redogöra för reglerna kring avveckling av dödsbon i Sverige, d.v.s. reglerna om dödsboförvaltning och arvskifte. Behandlingen inriktar sig framför allt på formerna för förvaltningen – vem som har rätt att företräda dödsboet, hur denna behörighet uppkommer och vad den består i. Fokus ligger på hur dödsbodelägarnas samarbete är reglerat och vilka lösningar lagen erbjudThe aim of this thesis is to account for the rules surrounding the administration and distribution of the estate of a deceased person in Sweden. The study is concentrated on the personal representative, i.e. who has the right to administer an estate on death, how this authority arises and what it consists of. The main focus lies on the regulation of the joint administration of the beneficiaries of
As a magnetic resonance imaging (MRI) examination lasts about 45 minutes and as the technique is sensitive to motion, children are often given sedation or anesthesia. The aim of this study was to examine whether children aged three to nine years could undergo MRI while awake and achieve adequate image quality if age-adjusted routines were used. A two-group controlled experimental design was used.
By using a case study of a smallscale fishing community in the Mediterranean Sea, Sigri (Lesvos, Greece), this thesis aims at exploring the drivers and barriers for an effective local implementation of the target Good Environmental Status by 2020. The future of the Mediterranean Sea is increasingly linked to the people who live by its coasts and depend on it for their livelihoods. On the other han
Precipitation and air temperature are key drivers of watershed models. Currently there are many open-access gridded precipitation and air temperature datasets at different spatial and temporal resolutions over global or quasi-global scale. Motivated by the scarcity and substantial temporal and spatial gaps in ground measurements in Africa, this study evaluated the performance of three open-access
Policy-makers are starting to acknowledge the urgent need for policy-intervention to achieve sustainable consumption. However, it is difficult to achieve policy-making that leads to impactful consumption interventions. Generally speaking, sustainable consumption can be achieved in three ways; to reduce consumption, to change consumption, and to improve consumption. These strategies all have their
BACKGROUND: Shared decision-making (SDM) between clinicians and patients is one of the pillars of the modern patient-centric philosophy of care. This study aims to explore SDM in the discipline of trauma and emergency surgery, investigating its interpretation as well as the barriers and facilitators for its implementation among surgeons.METHODS: Grounding on the literature on the topics of the und
Background: Patients undergoing allogeneic haematopoietic stem cell transplantation (allo-HCT) often face complex and evolving needs throughout recovery. Person-centred nursing (PCN) is essential in this context yet remains underexplored in specialised care settings. In Sweden, the Assessment of Rehabilitation Needs Checklist (ARNC) is commonly used in cancer care, but its role in supporting perso
Polyphagy is an adaptative strategy allowing species to develop and survive on multiple diets. Phytophagous insects can be exposed to sub-optimal resources, as host plants vary in nutritional quality. Some insects may rely on symbiotic bacteria to better utilize less favorable substrates. The invasive fruit fly Drosophila suzukii is a highly successful pest worldwide. The use of ripening and ripe
We report here on a procedure to obtain large amounts of a chloroplast-localized heat shock protein (HSP21) with unknown structure and function, by using anEscherichia coliexpression system for the pea (Pisum sativum) protein and a purification procedure based on perfusion ion-exchange chromatography. After initial precipitation steps, the sample was applied to cation- and anion-exchange on two co
Background and Objective: Glioblastoma multiforme is a highly malignant primary brain tumor. It has no border but at best a marginal zone, however, invisible to the surgeon. An optical touch pointer (OTP) enabling differentiation of healthy and tumor tissue by means of fiber-optic fluorescence spectroscopy has been developed. In combination with an ultrasonic navigation system, the OTP may be used
This engineering design guideline is intended for wood in outdoor above ground applications, i.e. use class 3 according to EN 335. It is based on a prescribed limit state for onset of decay during a reference service life of 30 years. Onset of decay is defined as a state of fungal attack according to rating 1 in EN 252. The approach is to determine the climate exposure as a function of geographica
Effective human input devices for computer control are very important to quadriplegics and others with severe disabilities. This paper describes a framework for computer control without need for special PC software or drivers. The framework is based on a tongue control system recently developed at Center for Sensory-Motor Interaction (SMI), Aalborg University. The framework provides emulation of a
