The Multi-Blade is a Boron-10-based gaseous detector introduced to face the challenge arising in neutron reflectometry at pulsed neutron sources. Neutron reflectometers are the most challenging instruments in terms of instantaneous counting rate and spatial resolution. This detector has been designed to cope with the requirements set for the reflectometers at the upcoming European Spallation Sourc

Nano and micro structured thin (μ m-scale) foils were designed, fabricated and irradiated with the high intensity laser system operating at LLC (Lund Laser Centre, Sweden) in order to systematically study and improve the main proton beam parameters. Nano-spheres deposited on the front (laser irradiated) surface of a flat Mylar foil enabled a small enhancement of the maximum energy and number of th

We present a model featuring heterogeneous households with a conspicuous consumptionmotive, in which inequality can decrease financial stability, and relate this behavior to the recent financial crisis in theUSA. A natural policy conclusion would be to combat income inequality jointly with financial instability by means of a progressive system of taxes and transfers. We investigate this for the ca

One of the great challenges of modern condensed matter theory is to develop reliable and practical methods for describing the electronic structure of strongly correlated materials fully from first principles. It has been known for a long time that the widely used Kohn-Sham density functional theory within the local density approximation (LDA) often fails for these systems. This paper describes the

Some problems in biological wastewater treatment control are discussed. The reason for control is disturbances, and some important operational problems are described. The control means available for an activated sludge process are considered. Available dynamical models are reviewed briefly and a survey of current practice in control is given.

Constructive alignment is the pedagogical principal which connects learning goals and learning activities with assessment. Learning goals should inform the student about what they’ll know once they finish the course. Learning activities is what the student needs to do to fulfill the goals. The assessment measures to what degree the student reaches the learning goals. The principal of constructive

This work concerns the program for Monte Carlo (MC) simulation of three-body decays data. Three-body events are characterized by complicated correlations hindered by induced distortions due to finite resolution of experimental setups. The MC code is developed and tested by performing the analysis of the 10He experiment which shows the unusual order of first excited states of 10He.

Eukaryotic phytoplankton exhibit an enormous species richness, displaying a range of phylogenetic, morphological and physiological diversity. Yet, until recently, very little was known about the diversity, genetic variation and evolutionary processes within species and populations. An approach to explore this diversity and to understand evolution of phytoplankton is to use population genetics as a

Många kommuner i Sverige ställer krav på miljöbilar i upphandlingen av kommunala tjänstebilar, och en del ställer även specifika krav på elbilar. Detta projekt har utvärderat offentlig upphandling för att svara på frågor om vilken potential upphandling har för att främja förnybara drivmedel, vilka de praktiska erfarenheterna är, huruvida offentlig upphandling används strategiskt och hur styrmedlet

Summary-The role of stress in the development of disease has been the subject of considerable research in the last few years. Stressful life events have been related to many physical and psychological disorders. The DSM-IV devoted Axis IV to these kinds of events. There is, however, scant information on the possible mediating role of sex on perception of stressful life events, or on the validation

We examined the convergent validity of three posttraumatic symptoms inventories, the civilian version of the Mississippi Scale for Combat-Related PTSD (CM-PTSD), the Trauma Symptom Checklist-40 (TSC-40), and the Response to Childhood Incest Questionnaire (RCIQ), in a sample of 52 adult sexual abuse survivors. The significant and moderate to strong correlations (r = .6 or higher) among these invent

Objective: To develop and assess the efficacy of a multimodal balance-enhancing exercise program (BEEP) designed to be regularly self-administered by community-dwelling elderly. The program aims to promote sensory reweighting, facilitate motor control, improve gaze stabilization, and stimulate continuous improvement by being constantly challenging. Method: Forty participants aged 60 to 80 years pe

OBJECTIVE: Outcome after treatment of vestibular schwannomas can be evaluated by health providers as mortality, recurrence, performance, and morbidity. Because mortality and recurrence are rare events, evaluation has to focus on performance and morbidity. The latter has mostly been reported by health providers. In the present study, we validate 2 new scales for patient-assessed performance and mor

Vertigo is one of the most common complaints in medicine. Despite its high prevalence, patients with vertigo often receive either inappropriate or inadequate treatment. The most important reasons for this deplorable situation are insufficient interdisciplinary cooperation, nonexistent standards in diagnostics and therapy, the relatively rare translations of basic science findings to clinical appli
