The revision of Pilosella presented by the author in 2001 is here updated with new records and taxa, and recent international advancements in the field are briefly presented and discussed. The taxonomy of the previous revision, based on the "genotypic cluster species concept" of Mallet and the principles that species should be circumscribed as groups of individuals whose intermediates are rare and

The present work is an example of a Direct-Current resistivity and time-domain Induced Polarization (DCIP) survey, carried out in an urban environment. The main goal of the survey is to map a weak zone in the bedrock, through which a tunnel will be constructed. Geophysical measurements in urban environments can be very complicated due to the restrictions of available space and the high levels of n

Background: People with psychosis have a reduced life expectancy of 10-20years, largely due to cardiovascular disease. This trial aimed to determine the effectiveness of a modular health promotion intervention (IMPaCT Therapy) in improving health and reducing cardiovascular risk in psychosis. Methods: A multicentre, two arm, parallel cluster RCT was conducted across five UK mental health NHS trust

The spectral induced polarization (SIP) method is a promising method for many near surface applications, including characterization of contaminated soil. In this study, SIP measurements, high-resolution X-ray tomography and image analysis are combined to investigate clean and tetrachloroethylene (PCE) contaminated sand. This is the first known combination of these methods and the aim of this paper

A geophysical site investigation using ERT and refraction seismic was done to detect the bedrock interface and possible weakness zones. For the purpose of a more realistic subsurface model a joint inversion was done.

Estimation of hydraulic parameters of the vadose zone is a relevant issue in hydrological characterization and flow model calibration. Two borehole Ground Penetrating Radar (GPR) techniques are discussed: Zero-Offset Profiling (ZOP) and Vertical Radar Profiling (VRP). The field case is representative of a very common situation in vadose zone characterization: Above the water table, the permittivit

Recently there is an increasing interest in the understanding of the Spectral Induced Polarization (SIP) phenomenon in porous media. The complex electrical conductivity of porous geological materials has a frequency dependent behavior than can be associated to three main mechanisms: Maxwell-Wagner (MW) polarization, Membrane polarization, Electrical double layer (EDL) polarization. This paper aims

The visual systems of many animals, particularly those active during the day, are optimized for high spatial acuity. However, at night, when photons are sparse and the visual signal competes with increased noise levels, fine spatial resolution cannot be sustained and is traded-off for the greater sensitivity required to see in dim light. High spatial acuity demands detectors and successive visual

Geoelectrical techniques have long standing potential for imaging sites contaminated by dense non-aqueous phase liquids (DNAPLs). Recent work explored the effectiveness of time-lapse DC resistivity to monitor DNAPL source zone remediation. A fundamental component of the work was the development of a unique and comprehensive linkage between well-established DNAPL and DC resistivity models, with the

In this paper using time-series data for a large number of Islamic bank stocks belonging to eight Islamic countries we test for evidence of price discovery. We find that in each of the eight countries there appears a bank that dominates the price discovery process. We then utilize this information on price discovery to form a portfolio of price discovery dominating bank stocks and compare its perf

Globally, large international research infrastructures have over many decades promoted excellence in science and technology. Aligned with the international practice, the Europe Strategy Forum for Research Infrastructures (ESFRI) has developed and keeps updating a roadmap for research infrastructures. The Extreme Light Infrastructure (ELI) is one of the two large scale Laser Research Infrastructure

Historic differences in livelihoods, work roles and the access to resources lead to differences in how women and men are exposed to and impacted by climate change. Policymakers and civil society groups have come to realize that gender matters in the governance of climate issues and there is an emerging scholarship in this field. However, the attention is mainly on women, rather than on gender, for

This chapter offers a review of the literature in the field of critical security studies in order to discuss the various social constructions of climate change as a security issue and their policy implications. Will climate security discourse facilitate climate mitigation policy? First, the Copenhagen School asks whether extraordinary measures to protect the climate (including emission reductions)

Beskriver den assyriska folkgruppens historia i Sverige 1967-2017.

Whole exome sequence analysis was performed in a Swedish mother-father-affected proband trio with a phenotype characterized by progressive retinal degeneration with congenital nystagmus, profound congenital hearing impairment, primary amenorrhea, agenesis of the corpus callosum, and liver disease. A homozygous variant c.806T > C, p.(F269S) in the tyrosyl-tRNA synthetase gene (YARS) was the only id
