Cluster headache is a primary headache by definition not caused by any known underlying structural pathology. Symptomatic cases have been described, for example tumours, dissections and infections, but a causal relationship between the underlying lesion and the headache is difficult to determine in many cases. The proper diagnostic evaluation of cluster headache is an issue unresolved. The literat

Background: Shape coexistence in heavy nuclei poses a strong challenge to state-of-the-art nuclear models, where several competing shape minima are found close to the ground state. A classic region for investigating this phenomenon is in the region around Z = 82 and the neutron midshell at N = 104. Purpose: Evidence for shape coexistence has been inferred from a-decay measurements, laser spectrosc

Over the last 10 years, the use of nets to protect pome fruit from hailstorms has increased. In this study, we investigated the effect of these nets on the behavior of the codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), a major pest of apple, Malus domestica Borkh. (Rosaceae). Experiments were carried out in net-covered and uncovered apple orchards treated with conventional insectic

In the German camps during the Second World War, the aim was to kill from a distance, and the camps were highly efficient in their operations. Previous studies have thus analyzed the industrialized killing and the victims' survival strategies. Researchers have emphasized the importance of narratives but they have not focused on narratives about camp rituals, or analyzed post-war interviews as a co

This paper investigates trust behavior in situations where decision-makers are large groups and the decision mechanism is collective. Theories from behavioral economics and psychology suggest that trust in such situations may differ from interindividual trust. The experimental results here reveal a large difference in trust but not in trustworthiness between the individual and collective setting.

Developing large, complex software products aimed at broad markets involves identifying and maintaining the link between product requirements and the continuous, massive inflow of customers' wishes. The manual linkage performed today is cumbersome, time-consuming, and error-prone. Automating this support through linguistic engineering could save considerable time and improve software quality. This

Apparent standard Gibbs energy, enthalpy, entropy, and heat capacity data of the interactions of alpha-cyclodextrin (alphaCD) to some n-carboxylates H(CH2)(n)COO- (n = 4 - 6), are determined by isothermal titration microcalorimetry at different temperatures in phosphate buffer, pH 9.0, assuming a 1 : 1 model in dilute solution. Modelling of contributions of the thermodynamic properties of the solu

Introduction: Physical inactivity, low aerobic fitness and obesity are all associated with an increased risk of a wide range of diseases in adults. Promotion of physical activity, improvement of aerobic fitness and regulation of body weight in children may be of importance, as low physical activity, low aerobic fitness and obesity early in life have been known to track into adulthood. However, rel

We study the reflection and transmission phase properties of two-terminal quantum structures coupled to a third lead. The systems are effectively three-terminal and current conservation is broken with regard to the original two-terminal systems. Two structures, a waveguide with an attached stub quantum dot and a waveguide with an inline, double-barrier confined quantum dot, are considered. The tra

OBJECTIVE: To compare the rate of ischemic events and intracranial hemorrhage in the long-term follow-up of patients with persistent and transient severe stenosis or occlusion of the internal carotid artery (ICA) due to spontaneous dissection (ICAD). METHODS: One hundred and sixty-one consecutive patients with unilateral ICAD causing severe stenosis or occlusion were examined clinically and by ult

Several poly (dimethylsiloxanes) (PDMS) copolymers of dimethylsiloxane (DMS) with ethylene or propylene oxide were tested as artificial carriers for the delivery of oxygen to biological systems. Copolymers with a DMS content of 33% or lower enhanced glucose oxidation by 200% in contrast to the 25% increase produced by the same concentration of perfluorodecalin. When 0.05% of the copolymer with 18%

From a public database in Sweden we obtained a subject pool consisting of one group of 20 years old and another group exactly 50 years older. The groups participated in a mail-based trust game, in which the young cohort exhibited more trust than the older one. Subjects significantly preferred to place trust in co-players of their own cohort and of the female sex. When amounts sent and proportions

Norovirus (NoV) is a leading cause of gastroenteritis and genotype II.4 (GII.4) is responsible for the majority of nosocomial NoV infections. Our objective was to examine whether sequencing of the capsid gene might be a useful tool for the hospital outbreak investigation to define possible transmission routes. All NoV positive samples submitted from one university hospital during the 2007/8 season

A novel technique, designated dual imaging and modeling evaluation (DIME), for evaluating single-laser shot fluorescence lifetimes is presented. The technique is experimentally verified in a generic gas mixing experiment to provide a clear demonstration of the rapidness and sensitivity of the detector scheme. Single-laser shot fluorescence lifetimes of roughly 800 ps with a standard deviation of s

Syftet med rapporten har varit att analysera erfarenheterna av miljöanpassad upphandling och innovationsupphandling, samt hur dessa styrmdel kan bidra till uppfyllandet av olika politiska målsättningar. Rapporten redogör bl.a. för målsättningarna för upphandling, betydelsen av en efterfrågedriven innovationspolitik, samt hur upphandling kan samverka med andra styrmedel på miljöområdet.
