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

Sweden has a combination of public and private protection of legal expenses in civil cases. The public legal aid scheme is subsidiary to the legal expense insurance, which means anyone who had a legal expense insurance covering the current affair would not receive legal aid. The chapter aims at reviewing the current legal aid in the country with emphasis on the public legal aid scheme and the lega

There is evidence of poor prognosis in women with pregnancy-associated breast cancer (PABC) diagnosed during pregnancy or within 2 years of delivery. Using a large, population-based cohort, we examined clinicopathologic features and survival in women with PABC. A cohort of women diagnosed with invasive breast cancer between 1992 and 2009 at ages 15-44 years was identified in the Swedish Cancer Reg
