Abstract
The main objective of this experimental study is to determine the effect of low temperatures on the mechanical behaviour of Strenx 960 Plus high-strength structural steel at different strain rates and stress triaxialities. For this purpose, a comprehensive experimental campaign was designed to characterise the material at a wide range of temperatures and loading rates. The stress triaxiality was varied by testing specimens with different geometry. First, to determine the ductile-to-brittle transition temperature, instrumented Charpy V-notch impact tests were carried out at a range of temperatures from + 20 °C down to − 90 °C. The impact energy dropped gradually with decreasing temperature, but a clear transition temperature could not be identified. A fractography study exhibited a clear dimple structure, revealing predominantly ductile fracture at all temperatures. Then, uniaxial tension tests on smooth and pre-notched axisymmetric specimens under both quasi-static and dynamic loading rates were carried out at room temperature and low temperatures. These tests were conducted to characterise the rate-dependence of the stress–strain behaviour and the failure strain. The results revealed that under quasi-static conditions the flow stress increased with decreasing temperature, while the failure strain was nearly independent of the temperature. Dynamic tensile tests using the same specimen geometries were conducted in a split Hopkinson tension bar at + 20 °C and − 40 °C. The material exhibited a positive strain rate sensitivity at all investigated temperatures. This experimental study reveals that the Strenx 960 Plus steel retains its ductility at temperatures as low as − 40 °C. Brittle failure could not be observed even with combined high strain rate, high stress triaxiality and low temperature.
Adoption of Cover Crops by U.S. Soybean Producers
Authors: Lee Seungyub , McCann Laura 
Published: June 2019

AbstractUsing cover crops can be beneficial not only for soil health but also for the environment. However, relatively few farmers have adopted cover crops, so understanding the barriers to adoption is necessary. We used a probit model with data on 1,712 soybean producers from the 2012 USDA Agricultural Resource Management Survey to identify factors affecting adoption of cover crops. We found that more precipitation was positively correlated with adoption, as was more hired labor. Adoption was also positively correlated with crop diversification and no-till adoption, which may relate to equipment availability.
Thermally induced icequakes detected on blue ice areas of the East Antarctic ice sheet

Published: June 2019

ABSTRACTOver a year of seismic observations, ~5000 short duration icequakes were detected by a permanent broadband station installed at the Princess Elisabeth base, located ~180 km inland in eastern Dronning Maud Land, East-Antarctica. Icequake detection via seismic waveform pattern recognition indicates the presence of two dominating clusters of events, totalizing ~1500 icequakes. The corresponding icequake locations point towards two distinct zones of outcropping blue ice areas (BIAs) located respectively at 4 and 1 km from the seismic station, both on the leeward side of a nunatak protruding through the ice sheet. The temporal occurrence of these icequakes suggests a close genetic link with thermal contraction of ice caused by significant surface cooling controlled, in summer by variations in diurnal solar radiation and in winter by strong cooling during cold katabatic regimes. Further analysis demonstrates the dependence of these icequakes on the absolute surface temperature and on its temporal change. Besides providing information on the ice fracture mechanics and rheology, investigations of thermal icequakes may be regarded as a ground-based proxy for the monitoring of the thermal state of BIAs, and characterization of ice-sheet ablation zones.

Authors: Frederico Margarita , Cox Allison , Hameed Mohajer A. 
Published: June 2019

AbstractThe service user experience of children, their families and other stakeholders in a therapeutic program should inform quality of care, practice and organisation of services. Children referred to Take Two are clients of Child Protection for whom abuse and neglect have been substantiated. This paper aims to describe the development of the Take Two Stakeholder Survey, as well as to examine the reliability and factorial structure of the survey. In addition, the experience of consumers utilising the service will be described together with recommendations for clinical practice improvements and enhanced consumer engagement.
Harnessing the power of cultural health narratives when working with parents of young children
Authors: Rogers Marg 
Published: June 2019

AbstractNarratives are a powerful tool for transferring knowledge and culture. They have a profound effect on our psyche and our attitudes to messages and teachings. The transfer of information through traditional teaching and lectures is often less effective in changing a belief or understanding than using narrative. In this discussion paper, I explore this phenomenon and examine the persuasive effect of cultural narratives. The discussion also considers the impacts of cultural narrative as an educative tool on parental attitudes towards childhood immunisation. I explore the changing nature of the way parents with young children communicate and seek information and early childhood educators’ roles in their lives within the Australian context. Understanding the way humans are drawn to narrative may be beneficial to health workers, early childhood educators, family workers and those who plan health education programmes. To effectively target their messages, it would be of benefit to public health officials to have knowledge about how parents with young children inform themselves and develop health beliefs, and the extent to which parents’ ideas become fixed.

Published: June 2019

ABSTRACT:Background:Clinical trials with percutaneous vertebral augmentation (PVA) for intractable pain from vertebral compression fractures (VCF) have shown variable results. Variation in the outcomes may be related to poor patient selection on imaging.Objective:To assess if PVA augmentation for osteoporotic VCF results in better improvement in pain when patients were selected based on clinical examination plus imaging vs clinical examination only.Results:A systematic review and meta-analysis were performed. PubMed, Embase and Cochrane Library databases were searched from 2000 to May 2018. Two reviewers independently screened and extracted data to identify randomised control trials (RCTs) on PVA for osteoporotic VCF and assessed the risk of bias. Standard systematic review and meta-analysis methods were advocated by the Cochrane Collaboration and PRISMA Statement. A total of 12 RCTs with 1110 participants met the inclusion criteria. Eight of the 10 studies (938 participants) that used imaging to confirm oedema in the target vertebral bodies showed PVA (compared to nonsurgical treatment) was effective in reducing pain (immediate term: mean difference (MD) of −1.89; 95% confidence interval −1.93 to −1.85, p < 0.001; short term: MD of −1.68; 95% CI −1.82 to −1.54, p < 0.001; intermediate term: MD of −2.04; 95% CI −2.15 to −1.94, p < 0.001 and long term: MD of −1.88; 95% CI −1.95 to −1.80, p < 0.001).Conclusions:RCTs using imaging to confirm marrow oedema in the index vertebra showed an improved size effect compared to RCTs using no imaging. This benefit was observed in the immediate, short, intermediate and long term.

Published: June 2019

ABSTRACTThe capacity to rapidly distinguish Ebola virus disease from other infectious diseases and to monitor biochemistry and viremia levels is crucial to the clinical management of suspected Ebola virus disease cases. This article describes the design and practical considerations of a laboratory straddling the high- and low-risk zones of an Ebola treatment center to produce timely diagnostic and clinical results for informed case management of Ebola virus disease in real-life conditions. This innovation may be of relevance for actors requiring flexible laboratory implementation in contexts of high-communicability, high-lethality disease outbreaks.
The Future of International Law is Cognitive—International Law, Cognitive Sociology and Cognitive Pragmatics
Authors: Pirker Benedikt , Smolka Jennifer 
Published: June 2019

AbstractScholars today discuss international law from various methodological angles. This Article aims to add perspectives from cognitive science, namely cognitive sociology and cognitive linguistics, or, to be more precise, cognitive pragmatics. It briefly elaborates on these fields’ respective approaches, benefits, and limits. To clearly delineate the usefulness of the methodologies, this Article separately applies both approaches to the same example of a process of interpretation in international law. This Article concludes that the two cognitive approaches can help lawyers better understand and implement international law. This not only provides a description of the process of interpretation, but will hopefully enable a better practice of international law.
Responsibility and Rights
Authors: Dellavalle Sergio 
Published: June 2019

AbstractA new era of responsibility seems poised to overshadow the human rights discourse in international law. On the one hand, introducing the perspective of responsibility must result in an added value when compared to the former predominant approach. In fact, some justifications are inconsistent, and the most radical interpretations jeopardize the very core of the modern theory of social and legal order—namely, the centrality of the individual. On the other hand, the incorporation of responsibility into the discourse on rights may help to overcome some of its most evident shortcomings. Nonetheless, despite some positive outcomes which the new attention on responsibility may bring about, the concept is flawed by at least two major deficits. First, the reference to responsibility tends to presuppose the possibility of taking the position of a privileged observer. This implicitly rejects the idea that the moral and legal community is essentially constituted by human individuals who freely recognize each other as equal members and rightful holders of entitlements. The second deficit is instead related to the intrinsically particularistic character of responsibility, which makes it rather difficult to apply to the field of international law and relations. An analysis shows that we are confronted with a conflict: while responsibility can, in fact, be assumed to bring an added value, the costs for this are exceedingly high, because they amount to no less than the abandonment of the core concept of modern moral and political philosophy. By recurring to the communicative paradigm of rationality and social order, a possible solution is outlined according to which responsibility is reinterpreted in the sense of a time, space, composition, and content-related expansion of mutual recognition.
Advances in the prevention and management of central-line–associated bloodstream infections: The role of chelator-based catheter locks

Published: June 2019

AbstractThe proper functioning of central lines is imperative for the management of patients with cancer or on hemodialysis. However, these lifelines can become infected and can malfunction.Chelators such as citrate and EDTA have been widely studied alone or in combination with other antimicrobial agents in catheter lock solutions to prevent catheter-related bloodstream infections and to maintain catheter patency. Given their anticoagulation, antiplatelet aggregation, antibiofilm, antimicrobial activity, safety profile, as well as their low cost, chelators have long been considered alternatives to heparin and a vital component of catheter lock solutions. In this review, we present a detailed summary of the properties of chelators and in vitro and in vivo studies of chelator-containing lock solutions.
The case for a population standardized infection ratio (SIR): A metric that marries the device SIR to the standardized utilization ratio (SUR)

Published: June 2019

AbstractBackground:The device standardized infection ratio (SIR) is used to compare unit and hospital performance for different publicly reported infections. Interventions to reduce unnecessary device use may select a higher-risk population, leading to a paradoxical increase in SIR for some high-performing facilities. The standardized utilization ratio (SUR) adjusts for device use for different units and facilities.Methods:We calculated the device SIR (calculated based on actual device days) and population SIR (defined as Σ observed events divided by Σ predicted events based on predicted device days), adjusting for the facility SUR for both central-line–associated bloodstream infections (CLABSIs) and catheter-associated urinary tract infections (CAUTIs) in 84 hospitals from a single system for calendar years 2016 and 2017.Results:The central-line SUR was 1.02 for 801,172 central-line days, with a device SIR of 0.76 and a population SIR of 0.78, a 1.6% relative increase. On the other hand, the urinary catheter SUR was 0.90 for 757,504 urinary catheter days, with a device SIR of 0.84 and a population SIR of 0.76, a 10.0% relative decrease. The cumulative attributable difference for CAUTI to a target SIR of 1 was −135.4 for the device SIR compared to −203.66 for the population SIR, a 50.8% increase in prevented events.Conclusion:Population SIR accounts for predicted device utilization; thus, it is an attractive metric with which to address overall risk of infection or harm to a patient population. It also reduces the risk of selection bias that may impact the device SIR with interventions to reduce device use.
Coerced Migration and Resettlement in the Qin Imperial Expansion
Authors: Barbieri-Low Anthony J. 
Published: June 2019

AbstractDuring the century of massive expansion of the Qin state in China (ca. 316–222 BCE), and the subsequent fifteen years of the empire (221–207 BCE), it is recorded that millions of persons were forcibly relocated and resettled throughout the empire and along its frontiers. For example, the historian Sima Qian (ca. 145–86 BCE) states that in just the years between 213 and 210 BCE, the First Emperor relocated more than a million people from interior counties of the empire to settle newly-conquered lands on the northern and southern frontiers. Yet this was only one type of forced resettlement carried out by the Qin. The Qin state also relocated thousands of aristocratic households from conquered states to the Qin capital of Xianyang, captured large numbers of non-Chinese peoples and assigned them to localities as slaves to open up agricultural land, exiled wealthy iron industrialists from the interior to the periphery, intentionally expelled the entire populations of conquered cities to replace them with amnestied criminals, and pooled and redirected the labor of convicts gathered from throughout the empire to labor on huge projects such as the First Emperor's tomb. This article seeks to analyze and categorize these various Qin forced resettlements to uncover the ideological and policy motivations behind them and the role they played in the larger project of Qin imperial expansion and colonization.

Published: June 2019

ABSTRACTWhile assessing the environmental impact of nuclear power plants, researchers have focused their attention on radiocarbon (14C) owing to its high mobility in the environment and important radiological impact on human beings. The 10 MW high-temperature gas-cooled reactor (HTR-10) is the first pebble-bed gas-cooled test reactor in China that adopted helium as primary coolant and graphite spheres containing tristructural-isotropic (TRISO) coated particles as fuel elements. A series of experiments on the 14C source terms in HTR-10 was conducted: (1) measurement of the specific activity and distribution of typical nuclides in the irradiated graphite spheres from the core, (2) measurement of the activity concentration of 14C in the primary coolant, and (3) measurement of the amount of 14C discharged in the effluent from the stack. All experimental data on 14C available for HTR-10 were summarized and analyzed using theoretical calculations. A sensitivity study on the total porosity, open porosity, and percentage of closed pores that became open after irradiating the matrix graphite was performed to illustrate their effects on the activity concentration of 14C in the primary coolant and activity amount of 14C in various deduction routes.

AbstractThe number of people avoiding gluten is growing in many Western countries. However, little information is available on their sociodemographic and dietary profiles. We aimed to describe sociodemographic, behavioural and dietary profiles of participants avoiding gluten in the NutriNet-Santé cohort. Participants of the NutriNet-Santé cohort – excluding coeliac patients – who completed a questionnaire about food exclusions, with complete data on sociodemographic characteristics and dietary intake were included (n 20 456). Food group consumptions and nutrient intakes according to self-reported avoidance of gluten were estimated using ANCOVA adjusted for age, sex and daily energy intake. Based on principal component analysis, three dietary patterns (DP) were identified. Association between DP and avoidance of gluten was investigated using multivariate logistic regression. All data were weighted on the French census. A total of 10·31 (95 % CI 9·90, 10·73) % of the participants declared avoiding gluten, of which 1·65 % totally. They were more likely to be women, older persons, non-smokers, to have a lower educational level and declared more food intolerances. They had higher consumption of fruit, vegetables and lower consumption of dairy products, salty/sweet and fatty foods and alcohol. After adjustments on confounders, a healthy dietary pattern was positively associated with total gluten avoidance (ORQuintile5vsQuintile1 = 14·44, 95 % CI 8·62, 24·19). Our study highlighted that, in this population, individuals who avoid gluten from their diet tend to have a diet more favourable to health. These results can serve as a basis for future studies investigating the potential consequences of a gluten-free diet in non-coeliac population.

Published: June 2019

AbstractIncreased attention has been paid to circadian patterns and how predisposition to metabolic disorders can be affected by meal timing. Currently, it is not clear which role can be attributed to the foods selected at meals. On a cross-sectional sub-cohort study (815 adults) within the European Prospective Investigation into Cancer and Nutrition-Potsdam study, we investigated whether the same foods (vegetables, fruits, refined grains, whole grains, red and processed meats) eaten at different meals (breakfast, lunch or dinner) show different associations with biomarkers of cardiometabolic risk. Meal-specific usual intakes were calculated from multiple 24-h dietary recalls. Multivariable-adjusted linear regression models showed that intake of vegetables at breakfast was associated with lower LDL-cholesterol (−0·37 mmol/l per 50 g; 95 % CI −0·61, −0·12) and vegetables at dinner was associated with higher HDL-cholesterol (0·05 mmol/l per 50 g; 95 % CI 0, 0·10). Fruit intake at breakfast was associated with lower glycated Hb (HbA1c) (−0·06 % per 50 g; 95 % CI −0·10, −0·01) and fruits at dinner with lower C-reactive protein (CRP) (−0·21 mg/l per 50 g; 95 % CI −0·42, −0·01). Red and processed meat intake at breakfast was associated with higher HbA1c (0·25 % per 50 g; 95 % CI 0·05, 0·46) and CRP (0·76 mg/l per 50 g; 95 % CI 0·15, 1·36). Our results suggest that by preferring fruits and vegetables and avoiding red and processed meats at specific meals (i.e. breakfast and dinner), cardiometabolic profiles and ultimately chronic disease risk could be improved. Lunch seemed to be a less important meal in terms of food–biomarker associations.
Tokoro Belt (NE Hokkaido): an exhumed, Jurassic – Early Cretaceous seamount in the Late Cretaceous accretionary prism of northern Japan

Published: June 2019

AbstractThe Tokoro Belt exposed in NE Hokkaido (Japan) represents part of a Late Cretaceous accretionary complex, which includes variously metamorphosed volcanic rocks that are interbedded with chert, lenticular limestone and some fore-arc sedimentary rocks. The Tokoro Belt is notably different from other Late Cretaceous accretionary complexes around the Pacific Rim because of widespread occurrence of basalts and volcaniclastic rocks in it. The Nikoro Group, characterized by widespread occurrence of volcanic rocks, is divided into western, eastern and southern sections based on the internal structure, geochemical affinities and metamorphic grades of their volcanic lithologies. OIB (ocean island basalt)-type volcanic rocks with low-grade metamorphic overprint predominate in the western and southern sections, whereas MORB (mid-ocean ridge basalt)- and OIA (ocean island alkaline basalt)-type rocks in the eastern section with partly high-pressure metamorphism make up the northern part of the eastern section. Trace element patterns display transitional trends from MORB to OIA geochemical affinities. OIB-type rocks display trace element characteristics similar to those of shield volcano lavas on Hawaii, rather than small and mainly alkaline, Polynesian hotspot lavas; furthermore, they show significant HREE (heavy rare earth element) enrichment probably caused by plume–ridge interaction. Widespread OIBs in the Tokoro Belt represents tectonic slices of a large (>80 km wide) Hawaiian-style, seamount shield volcano on the Izanagi oceanic plate that was accreted into the continental margin of Far East Asia in the Late Cretaceous.
