New Three-component Landstreamer System Developed for Groundwater and Engineering Applications

A new landstreamer system has been developed that provides high resolution imaging from near surface to medium depths. The system is comprised of a combination three-component array to acquire SH data for near surface and a single component array to acquire typical P-wave data at depth. The first application of the system is being carried out for a groundwater mapping project where detailed knowleA new landstreamer system has been developed that provides high resolution imaging from near surface to medium depths.

Catquest-9SF questionnaire shows greater visual functioning in bilateral cataract populations : A prospective study

Purpose: Visual functioning evaluated by the Catquest-9SF questionnaire has shown to be a valid measure for assessing a patient's prioritization for cataract surgery. This study adapted Catquest-9SF for visual function outcomes post uni-lateral cataract surgery or bi-lateral cataract surgery. Methods: Visual functioning was assessed before and after uni-lateral or bi-lateral cataract surgery using

Surface and Borehole Refraction Surveys in Copenhagen, Denmark

Seismic refraction imaging is a technique that has seen an increase of applications in engineering during recent years. In the work presented here a case of refraction tomography in the city of Copenhagen is discussed. The survey included two modalities; 1. a surface survey where 13.9 kilometers of crooked lines along segments of the planned underground metro were mapped, 2. borehole “walk-away” sSeismic refraction imaging is a technique that has seen an increase of applications in engineering during recent years.

This work presents a case where a combination of electromagnetics (EM61), refraction seismic surveys and a geotechnical survey allowed a detailed mapping of the near surface at a soil depot.This work presents a case where a combination of electromagnetics (EM61), refraction seismic surveys and a geotechnical survey allowed a detailed mapping of the near surface at a soil depot. Such results together with knowledge of the glacial overburden and groundwater potential enabled accurate determination of digging depth within the area, and thereby optimizing extension of the soil depot. The

Rydberg atomic antenna in strongly driven multielectron atoms

We study the role of intermediate excitations of Rydberg states as an example of Kuchiev's "atomic antenna"in above-threshold ionization of xenon, in particular their effect on the coherence between the spin-orbit-split states of the ion. We focus on the case of a laser frequency close to resonant with the spin-orbit splitting, where a symmetry (parity) argument would preclude any coherence being

A Novel Method for Smart Fire Detection Using Acoustic Measurements and Machine Learning : Proof of Concept

Fires are a major hazard resulting in high monetary costs, personal suffering, and irreplaceable losses. The consequences of a fire can be mitigated by early detection systems which increase the potential for successful intervention. The number of false alarms in current systems can for some applications be very high, but could be reduced by increasing the reliability of the detection system by us

Human Rights of Children in the Context of Migration Processes : Innovative Efforts for Integrating Regional Human Rights Standards in the Americas

This paper proposes a critical analysis of the innovative jurisprudential approaches taken by the Inter-American Court of Human Rights in integrating the content and scope of protection of the human rights of children, in the context of migration processes. How might one provide an effective protection to unaccompanied children that enter irregularly into the territory of a given country, when the

Refugee Integration in European Human Rights Law and EU Law : A Right to be Integrated?

Refugee integration is a highly politicised topic and is rarely analysed from a legal perspective. This contribution aims to address this gap by tracing the potential of the right to be integrated in legal terms, analysing its legal sources in European human rights law, and in European Union (EU, the Union) law, using a doctrinal method. It answers the question: is there a state obligation to prov

Monitoring and diagnosis of intermittent arrhythmias : evidence-based guidance and role of novel monitoring strategies

Technological advances have made diagnosis of heart rhythm disturbances much easier, with a wide variety of options, including single-lead portable devices, smartphones/watches to sophisticated implantable cardiac monitors, allowing accurate data to be collected over different time periods depending on symptoms frequency. This review provides an overview of the novel and existing heart rhythm test

Muscle mass and quality as predictors for complications, recurrence and length of hospital stay in acute uncomplicated diverticulitis: a retrospective cohort study

ObjectivesThe aim of this study was to investigate the potential correlation between muscle mass/muscle quality and risk of complications or recurrence in patients presenting with acute uncomplicated diverticulitis. It was also to study if low muscle mass/quality correlated to prolonged hospital stay.Materials and methodsThe study population comprised 501 patients admitted to Helsingborg Hospital
