An entity is described which is characterized by low back pain and increased radionuclide uptake in the sacrum at bone scintigraphy in postmenopausal women having received radiotherapy towards the pelvis because of gynaecological malignancy. The findings stimulate bone metastases, but are in all likelihood caused by insufficiency fractures of the sacrum promoted by bone weakness induced by postmen
Popular Abstract in Swedish Acceleratormasspektrometri, AMS, är en relativt ny metod för att bestämma extremt låga koncentrationer av såväl radioaktiva som stabila atomer. Metoden innebär att man med kärnfysikalisk teknik räknar atomerna en och en. De främsta fördelarna med AMS, jämfört med konventionella metoder, är att mycket små provmängder kan analyseras och att mättiden är kort. Mängden av eAccelerator mass spectrometry (AMS) is a highly sensitive method for counting atoms and it is used for detecting very low concentrations of both radionuclides and stable isotopes in small samples. The two major advantages of the AMS method are that the required amount of sample material is very small, but also that the efficiency is rather high, it takes less than an hour to analyse a sample. The
This paper considers how the challenges underpinning sustainable development are likely to impact on duty-and tax-free retailing in airports and, by implication, in the entire aviation industry. The paper defines the role of retail as a vital source of airport revenues, before considering the carbon consequences of the sector’s incumbent business models. It finds that products taken onto aircraft
The survivable network design problem is a classical problem in combinatorial optimization of constructing a minimum-cost subgraph satisfying predetermined connectivity requirements. In this paper we consider its geometric version in which the input is a complete Euclidean graph. We assume that each vertex v has been assigned a connectivity requirement r(upsilon).. The output subgraph is supposed
Many children with adverse reactions to beta-lactams are labelled as allergic without performing an allergy study to confirm it. In this retrospective study of 10 years, we have detected only 3.3% positive cases. Although International Guidelines recommend a second allergy work-up in patients with a negative study, we found from our results a low profitability of retesting.
Parkinson´s disease (PD) is a neurodegenerative disorder characterized by the typical motor symptoms, akinesia/bradykinesia, rigidity and resting tremor. These symptoms are caused by a deficiency of dopamine (DA) in the brain, which depends on degeneration of DA neurons in the substantia nigra. The most effective treatment for PD is the DA precursor, L-DOPA. Unfortunately, within a few years, L-DO
This paper raises a principled objection against the idea that Bayesian confirmation theory can be used to explain the conjunction fallacy. The paper demonstrates that confirmation-based explanations are limited in scope and can only be applied to cases of the fallacy of a certain restricted kind. In particular; confirmation-based explanations cannot account for the inverse conjunction fallacy, a
We have analyzed theoretically the Zeeman splitting of hole-quantum-wire subband edges. As is typical for any bound state, their g factor depends on both an intrinsic g factor of the material and an additional contribution arising from a finite bound-state orbital angular momentum. We discuss the quantum-confinement-induced interplay between bulk-material and orbital effects, which is nontrivial d
The leading cause of work related accidents in Sweden is falls. Many slips and falls occur on icy and snowy surfaces, but there is limited knowledge about how to prevent accidents during outdoor work in winter conditions. The purpose of this study was to describe risk factors of slips and falls and criteria for slip-resistant winter shoes from a user perspective. The result is based on focus group
Tungsten particles have been introduced into the National Spherical Torus Experiment (NSTX) in Princeton with the purpose to investigate the effects of tungsten injection on subsequent plasma discharges. An experimental setup for the study of tungsten particle transport is described where the particles are introduced into the tokamak using a modified particle dropper, otherwise used for lithium-po
The ability to tune the photon absorptance spectrum is an attracting way of tailoring the response of devices like photodetectors and solar cells. Here, we measure the reflectance spectra of InP substrates patterned with arrays of vertically standing InP nanowires. Using the reflectance spectra, we calculate and analyze the corresponding absorptance spectra of the nanowires. We show that we can tu
The recent financial crisis starting in 2007-2009 is the longest and the deepest recession since the Great Depression of 1930. The crisis that originated in the US subprime mortgage markets spread and amplified through international financial markets and resulted in severe debt crises in several European countries. Events revealed that the European Union (EU) had insufficient means to halt the spi
Quantum graphs having one cycle are considered. It is shown that if the cycle contains at least three vertices. then the potential oil the graph can be uniquely reconstructed from the corresponding Titchmarsh-Weyl function (Dirichlet-to-Neumann map) associated with graph's boundary, provided certain non-resonant conditions are satisfied
This thesis examines the possible transjudicial interaction that may arise between the ICC and the IACtHR with regard to the interpretation of the crime of enforced disappearance of persons. This potential scenario of jurisprudential cross-fertilisation is considered on the fact that both, the IACtHR and the ICC exercise jurisdiction ratione materiae over the crime of enforced disappearance, there
