A new Reference Material (RM) for radionuclides in mussel (Mytilus galloprovincialis) from the Mediterranean Sea (IAEA-437) is described and the results of the certification process are presented. Four radionuclides (K-40, U-234, U-238, and Pu239+240) have been certified, and information values on massic activities with 95% confidence intervals are given for nine radionuclides (Cs-137, Pb-210(Po-2

The growing need for valid assessment procedures of the outdoor thermal environment in the fields of public weather services, public health systems, urban planning, tourism & recreation and climate impact research raised the idea to develop the Universal Thermal Climate Index UTCI based on the most recent scientific progress both in thermo-physiology and in heat exchange theory. Following exte

Context. The Gaia satellite will observe about one billion stars and other point-like sources. The astrometric core solution will determine the astrometric parameters (position, parallax, and proper motion) for a subset of these sources, using a global solution approach which must also include a large number of parameters for the satellite attitude and optical instrument. The accurate and efficien

Objective: To describe patients' experience of acupuncture treatment in low back and pelvic pain during pregnancy. Design: An intervention study carried out between September 2000 and December 2001, involving 40 pregnant women. Participants: The study population consisted of healthy pregnant women presenting with low back and pelvic pain at maternity health care centres within a defined area in so

The origin of two large peaks in the atmospheric radiocarbon ((14)C) concentration at AD 774/5 and 993/4 is still debated. There is consensus, however, that these features can only be explained by an increase in the atmospheric (14)C production rate due to an extraterrestrial event. Here we provide evidence that these peaks were most likely produced by extreme solar events, based on several new an

In this review, we analyze several types of graphene-based sensors for glucose detection with respect to their preparation, properties and efficiency in electro-chemical processes. Graphene may display different types of defects, which play a role in the electron transfer processes. Oxygenated groups on the edges of graphene planes reduce the graphene in-plane conductivity, but may enhance the het

In this article we propose a modification of the recently introduced divergence information criterion (DIC, Mattheou et al., 2009) for the determination of the order of an autoregressive process and show that it is an asymptotically unbiased estimator of the expected overall discrepancy, a nonnegative quantity that measures the distance between the true unknown model and a fitted approximating mod

A search for a fermiophobic Higgs boson using diphoton events produced in proton-proton collisions at a centre-of-mass energy of root s = 7 TeV is performed using data corresponding to an integrated luminosity of 4.9 fb(-1) collected by the ATLAS experiment at the Large Hadron Collider. A specific benchmark model is considered where all the fermion couplings to the Higgs boson are set to zero and

This review summarises the evidence for the treatment of displaced fractures of the femoral neck in elderly patients. Results from randomised clinical trials and national register studies are presented when available. The advantages of arthroplasty compared with internal fixation are supported by several studies. A number of studies contribute to the discussions of total hip arthroplasty (THA) ver

The aim of this research paper is to explore how, and to what extent, the WIPO Marrakesh Treaty addresses the issue of restricted access to copyrighted materials by persons with visual impairments while securing legitimate interests and human rights of the central stakeholders; specifically, copyright rightholders and persons with visual impairments. In doing so, the focus centres on the compromis

Organizational identity has been mostly researched through a managerial perspective, where employees are given a secondary role. This thesis approaches identity from a dynamic perspective and explores how librarian identity is enacted in daily interactions between librarians and patrons, whilst considering any implications for the organization. The research focuses on a single case where participa

The principle of fiscal neutrality is the essence of the EU VAT system. It aims at relieving taxable persons of the burden of VAT through the deduction mechanism provided for by the VAT Directive. In its another aspect, the principle is a means of reflecting the equal treatment of taxable persons. The equal treatment of taxable persons ensures that taxable persons in a comparable situation are not

Simulations of large detectors such as the ATLAS detector at the LHC (Large Hadron Collider) are compute-intensive projects, and are according to current internal estimates expected to be consuming 40 % of the total ATLAS CPU resources in 2020, creating a need for software optimization strategies. We investigate build configurations of the Geant4 simulation software to find if a) a performance imp

We give a short overview of the theory of the muon anomalous magnetic moment with emphasis on the hadronic light-by-light and the pion loop contribution. We explain the difference between the hidden local symmetry and full VMD pion loop and discuss leading logarithms in the anomalous sector of 2-flavour chiral perturbation theory.

Background: Prognoses of most adult Hodgkin lymphoma (HL) patients are excellent; most of them can achieve permanent remission that can be considered cured. However, many are under-treated or over-treated by standard modern therapies. An accurate determination of prognosis may allow clinicians to design personalised treatment according to individual risk of disease progression and survival. Lympho

Physical activity is associated with lower risks of developing dementia, Parkinson’s disease (PD) and depression. Furthermore, being physically active prior to brain ischemia appears to help the recovery process. However, previous studies do not differentiate between the two most common forms of dementia, Alzheimer’s disease (AD) and vascular dementia (VaD), when it comes to the association betwee
