Authors: Chae Duckhee , Park Yunhee , Kang Kyeonghwa , Kim Jongdae 
Published: October 2019

BackgroundThere is lack of empirical evidence on whether organisational variables affect the cultural competence of nurses.AimThis study aimed to investigate individual and organisational characteristics associated with South Korean clinical nurses’ cultural competence.MethodsA descriptive cross‐sectional research design was used. A convenient sample of 401 clinical nurses from 21 hospitals in South Korea was recruited between November 2015 and February 2016. Multilevel modelling was used to estimate the effects of individual‐ and organisation‐level predictors. Data were analysed using the nlme package in R.ResultsMultilevel modelling indicated that professionalism (β = 0.02, p < 0.001) and foreign language fluency (β = 0.25, p = 0.012) were significant individual‐level predictors. Education on foreign patient care was marginally significant at p = 0.069. At the organisational level, nurse‐to‐patient ratio (β = 0.37, p = 0.038) and organisational cultural competence (β = 0.02, p < 0.001) were significant predictors. In addition, hospital ownership and work environment were marginally significant at p = 0.054 and p = 0.050, respectively. Furthermore, there was a significant cross‐level interaction between professionalism and hospital ownership (β = 0.03, p = 0.003).ConclusionTo provide culturally competent care, nurse leaders should recognise the importance of organisational‐level factors, such as nurse staffing and organisational cultural competence, and create an environment that is inclusive of diverse patients, as well as promote professionalism among individual nurses.

Published: October 2019

AbstractAimsTo explore the meaning of comfort and know the factors that contribute to it from the point of view of the young adults who received care in a paediatric intensive care unit, the family of the patient and the interdisciplinary team attending the patient.FindingsA total of 30 people were invited to participate in the focus groups; 24 did so. Thematic analysis yielded the following common categories: meaning of comfort, environmental factors in paediatric intensive care unit, family accompaniment during paediatric intensive care unit stay, management of information in the paediatric intensive care unit and, finally, the intimacy and privacy of the critically ill paediatric patient and their family.ConclusionsPaediatric intensive care unit professionals need to consider not only the environmental input that may lead to discomfort but also aspects such as continuous family accompaniment, the sharing of complete information with the family and the promoting of privacy.

AbstractHow do manufacturing exports react to the real exchange rate and to foreign demand? We investigate this question with a Chilean panel data spanning from 2003Q1 to 2016Q4, using publicly available data. In the long term, we find that exports strongly co‐integrate with external demand, whereas not with the level of the real exchange rate. The short‐run elasticities of manufacturing exports differ in size: (a) the elasticity of foreign demand—approximated by trading partners' activity aggregates—ranges between 0.8 and 1.4; and (b) the elasticity with respect to the bilateral real exchange rate is comprehended in the interval [0.4–0.6]. Core estimated elasticities pass usual robustness checks. The fall in manufacturing exports' growth in 2014–16 is consistent with a persistent slowdown in foreign demand, which has been partially offset by an average depreciation of the bilateral real exchange rate (with respect to destination countries of these exports). The transience of the effect of the real exchange rate is coherent with its exhibited stationarity and also consistent with its role of shock absorber.

We describe two approaches to modeling data from a small to moderate-sized epidemic outbreak. The first approach isВ based on a branching process approximation and direct analysis of the transmission network, whereas the second one is based on a survival model derived from the classical SIR equations with no explicit transmission information. We compare these approaches using data from a 2012 outbreak of Ebola virus disease caused byВ Bundibugyo ebolavirusВ in city of Isiro, Demo- cratic Republic of the Congo. The branching process model allows for a direct comparison of disease transmission across different environments, such as the general community or the Ebola treatment unit. However, the survival model appears to yield parameter estimates with more accuracy and better precision in some circumstances.
Stability Analysis of Rotating Systems Supported by Textured Journal Bearings
Authors: Jhon Ramos Douglas , Ito Ramos Leandro , Bregion Daniel Gregory 
Published: October 2019

Abstract
Fluid-induced instability in rotating systems due to the presence of hydrodynamic journal bearings consists of an undesirable phenomenon with a considerable destructive potential. Surface texturing of journal bearings is currently investigated as a possible approach to improve the stability characteristics of rotating systems. Thereby, this work aims to evaluate the influence of textured journal bearings in the stability threshold and unstable vibration mode of rotating systems. The classical Reynolds equation is used to model the pressure distribution inside the bearing, being solved by the finite volume method (FVM). The rotating system evaluated in this work is a steam turbine that is modeled using the finite element method (FEM). Numerical results show that textured geometric parameters, i.e., shape, area density, and maximum depth, are capable of changing the stability threshold (for worse or better) as well as the corresponding unstable vibration mode. Moreover, the present study also indicates that a full texturing of journal bearings is desirable to achieve a better improvement in the stability threshold when compared with partial texturing. Based on the results obtained in this work, the textured journal bearings represent a promising and feasible tool to improve the stability conditions of rotating systems in industrial applications.
Simulation, Test, and Mitigation of ½× Forward Whirl Following Rotor Drop Onto Auxiliary Bearings
Authors: Kang Xiao , Palazzolo Alan 
Published: October 2019

Abstract
1/2× forward whirl repeatedly occurred after a test rotor spinning at 5800 rpm was dropped onto ball bearing type auxiliary bearings (AB), utilized as a backup for magnetic bearings (MB). The measured contact forces that occurred between the rotor and the AB during the ½× subsynchronous vibration were about thirteen times larger than the static reaction force. The vibration frequency coincided with the rotor-support system natural frequency with the rotor at rest on the AB, an occurred at ½ of the rotor spin speed when dropped. The test rig provided measurements of rotor-bearing contact force, rotor orbit (vibrations), and rotational speed during rotor drop events. A simulation model was also developed and demonstrated that parametric excitation in the form of a Mathieu Hill model replicated the measured ½× forward whirl vibrations. The simulation model included a nonlinear, elastic-thermal coupled, ball bearing type AB model. The transient model successfully predicted the ½× vibration when the rotor was passing 5800 RPM as well, and the simulation results quantitatively agreed well with the test results in the frequency domain. Several approaches for mitigating the 1/2× forward whirl were presented such as adding an elastomer O-ring or waviness spring in the AB support system. Measurements confirmed that adding AB dampers effectively mitigated the ½ subsynchronous forward whirl and significantly reduced the contact forces.

Authors: Jia Yikai , Xu Jun 
Published: October 2019

Abstract
In recent years, safety-related accidents caused by lithium-ion battery (LIB) failures have often been reported and highlighted in the news. Thermal runaway (TR), as one of the most critical failure modes, and subsequent propagation can lead to catastrophic consequences for the battery pack or LIB module. In this study, TR propagation behavior between two batteries was studied. During the experiments, the TR of the first battery was triggered by mechanical abusive loading. The 3D thermal runaway model is combined with the electrical and thermal conduction model to construct a battery model for the TR model. Two typical TR propagation modes were observed and summarized from the simulation results according to different battery spacings. The mechanisms of these patterns are further discussed through the combination of computational models. High overall temperatures and localized overheating are the two main modes of TR propagation. The state of charge (SOC) is also a key factor that determines the probability and the speed of propagation. In addition, a simplified mathematical model is provided to improve the computational efficiency. Our results provide theoretical insights into the basic understanding of the TR propagation within battery packs. Results lay a strong foundation to develop an effective and efficient computing framework for the safe design of battery modules.
Effective Utilization of Solar Integrated Urban Distribution Network Infrastructure Using Diurnal Load Factor for Smart Cities
Authors: Muruganantham B. , Gnanadass R. 
Published: October 2019

Abstract
Solar PV Integration in the distribution network has become necessary to overcome the growing demand and to reduce emissions. The large percentage penetration of solar PV in the distribution network has more limitations to maintain the stability of the network. This paper emphasizes the strategy of location and the impact of solar PV integration in an urban distribution feeder. The urban distribution feeder has more service sector loads, having a majority of the demand during the daytime. To locate the solar PV, the diurnal load factor is proposed to maximize the utilization. With the proper location of solar PV in the appropriate nodes with more day demand, solar energy can be used locally without storage. This facilitates the effective utilization of urban distribution infrastructure, creating more network space for further load growth. The power flow and loading impact of solar PV generation are demonstrated on the 15-node Indian urban distribution feeder. Load profiles of various loads in different seasons of the year are normalized and grouped for the accurate analysis. Time series load flow analysis is performed with a variable load pattern to analyze the dynamic performance of the network.

Published: October 2019

Purpose: To identify the bar velocities that optimize power output in the barbell hip thrust exercise. Methods: A total of 40 athletes from 2 sports disciplines (30 track-and-field sprinters and jumpers and 10 rugby union players) participated in this study. Maximum bar-power outputs and their respective bar velocities were assessed in the barbell hip thrust exercise. Athletes were divided, using a median split analysis, into 2 groups according to their bar-power outputs in the barbell hip thrust exercise (“higher” and “lower” power groups). The magnitude-based inferences method was used to analyze the differences between groups in the power and velocity outcomes. To assess the precision of the bar velocities for determining the maximum power values, the coefficient of variation (CV%) was also calculated. Results: Athletes achieved the maximum power outputs at a mean velocity, mean propulsive velocity, and peak velocity of 0.92 (0.04) m·s−1 (CV: 4.1%), 1.02 (0.05) m·s−1 (CV: 4.4%), and 1.72 (0.14) m·s−1 (CV: 8.4%), respectively. No meaningful differences were observed in the optimum bar velocities between higher and lower power groups. Conclusions: Independent of the athletes’ power output and bar-velocity variable, the optimum power loads frequently occur at very close bar velocities.

Authors: Rodas Gil , Osaba Lourdes , Arteta David , Pruna Ricard , Fernández Dolors , Lucia Alejandro 
Published: October 2019

Purpose: The authors investigated the association between risk of tendinopathies and genetic markers in professional team sports. Methods: The authors studied 363 (mean [SD]; 25 [6] y, 89% male) elite players (soccer, futsal, basketball, handball, and roller hockey) from a top-level European team (FC Barcelona, Spain). Of 363, 55% (cases) had experienced 1+ episodes of tendinopathy during 2008–2018 and 45% (controls) remained injury free. The authors first examined the association between single-nucleotide polymorphisms (SNPs) and tendinopathy risk in a hypothesis-free case-control genome-wide association study (495,837 SNPs) with additional target analysis of 58 SNPs that are potential candidates to influence tendinopathy risk based on the literature. Thereafter, the authors augmented the SNP set by performing synthetic variant imputation (1,419,369 SNPs) and then used machine learning-based multivariate modeling (support vector machine and random forest) to build a reliable predictive model. Results: Suggestive association (P < 10−5) was found for rs11154027 (gap junction alpha 1), rs4362400 (vesicle amine transport 1-like), and rs10263021 (contactin-associated protein-like 2). Carriage of 1+ variant alleles for rs11154027 (odds ratio = 2.11; 95% confidence interval, 1.07–4.19, P = 1.01 × 10−6) or rs4362400 (odds ratio = 1.98; 95% confidence interval, 1.05–3.73, P = 9.6 × 10−6) was associated with a higher risk of tendinopathy, whereas an opposite effect was found for rs10263021 (odds ratio = 0.42; 95% confidence interval, 0.20–0.91], P = 4.5 × 10−6). In the modeling approach, one of the most robust SNPs was rs10477683 in the fibrillin 2 gene encoding fibrillin 2, a component of connective tissue microfibrils involved in elastic fiber assembly. Conclusions: The authors have identified previously undescribed genetic predictors of tendinopathy in elite team sports athletes, notably rs11154027, rs4362400, and rs10263021.
The origin of large gypsum crystals in the Geode of Pulpí (Almería, Spain)

Published: October 2019

Abstract
The Geode of Pulpí (Almería, Spain) is an ∼11 m3 ovoid cavity, the walls of which are covered with meter-sized idiomorphic and highly transparent gypsum (CaSO4●2H2O) crystals. We performed a thorough study based on field work, and petrographic and geochemical data collection, which aimed to reconstruct the geological history leading to the formation of this geode. The geode is hosted in mineralized Triassic carbonate rocks with a discontinuous mineral sequence from iron-carbonates and barite to celestine and finally gypsum (microcrystalline and selenite). Data from fluid inclusions show that barite precipitated above 100 °C, celestine at ∼70 °C, and gypsum below 25 °C. All δ34S sulfate phases fall between Triassic and Tertiary evaporite values. Barite and gypsum, either microcrystalline or large selenite crystals, show variable δ34S and δ18O compositions, whereas celestine and centimetric selenite gypsum have homogeneous values. We propose that the growth of the large selenite crystals in the Geode of Pulpí was the result of a self-feeding mechanism consisting of isovolumetric anhydrite replacement by gypsum at a temperature of 20 ± 5 °C, episodically contributed by a ripening process enhanced by temperature oscillations due to climatic change.

Published: October 2019

Abstract
Nineteen single-grain detrital garnet ages from a tributary to the French Broad River (North Carolina, USA) establish a novel approach to Sm-Nd detrital garnet geochronology wherein the equilibrium bulk-rock composition lost during weathering and transport is replaced with the composition of inclusions leached from within each garnet grain. Detrital garnet ages were compared to published detrital zircon and monazite ages from the same river tributary system. Results show that 87% of the zircons have inherited Proterozoic ages; only zircon rims give Paleozoic ages. Monazites are exclusively Ordovician (weighted average: 460.9 ± 3.0 Ma). Our new detrital garnet ages (and the detrital zircon rims) record younger ages spanning the Late Ordovician to Early Devonian, likely reflecting prolonged metamorphic heating. The weighted average age of the detrital garnet population is Silurian (430.1 ± 7.2 Ma). Statistical tests confirm that the garnet population is younger than the monazite. The new detrital garnet ages illuminate a previously uninterpreted Silurian tectonometamorphic signal in this region.

ObjectiveTo investigate to what extent being outside education, employment or training after completed secondary education in Sweden might affect the risk of subsequent alcohol use disorders (AUDs), with sociodemographic indicators, such as sex, domicile and origin, taken into account.DesignPopulation register-based cohort study with 485 839 Swedish youths.SettingSweden.ParticipantsAll youths who were born between 1982 and 1991 and were aged between 19 and 24 years when they completed secondary education in Sweden, between 2005 and 2009.Primary outcome measureCox regression models were used to estimate the HR of first record of entry into alcohol-related medical care with a diagnosis of an AUD, by level of labour market attachment, from 1 January 2009 to 31 December 2016.ResultsAbout 4% of the youth population were outside education, employment or training and 25% were in insecure workforce after they completed secondary education. The risk of AUD was higher among youths in insecure workforce, HR 1.40 (95% CI 1.30 to 1.50), and among those outside education, employment or training, HR 1.30 (95% CI 1.11 to 1.51), compared with youths within the core workforce, also after adjusting for age, domicile, sex and origin. Being in education was associated with lower HR of AUD, HR=0.84 (95% CI 0.78 to 0.90).ConclusionYouths who are in insecure workforce and outside education, employment or training are at higher risk of AUD. Targeted policy actions are needed to support a successful school-work transition to secure equal opportunities for young people.

Abstract.
Precision measurements of vector and tensor analyzing powers of the 2H( d, dp)n break-up process for configurations in the vicinity of the quasi-free scattering regime with the neutron as spectator are presented. These measurements are performed with a polarized deuteron-beam with an energy of 65MeV/nucleon impinging on a liquid-deuterium target. The experiment was conducted at the AGOR facility at KVI using the BINA 4$ \pi$π-detection system. Events for which the final-state deuteron and proton are coplanar have been analyzed and the data have been sorted for various momenta of the missing neutron. In the limit of vanishing neutron momentum and at large deuteron-proton momentum transfer, the data agree well with the measured and theoretically predicted spin observables of the elastic deuteron-proton scattering process. The agreement deteriorates rapidly with increasing neutron momentum and/or decreasing momentum transfer from the deuteron beam to the outgoing proton. This study reveals the presence of a significant contribution of final-state interactions even at very small neutron momenta.

Published: October 2019

Reactive security monitoring, self-driving cars, the Internet of Things (IoT), and many other novel applications require systems for both writing events arriving at very high and fluctuating rates to persistent storage as well as supporting analytical ad hoc queries. As standard database systems are not capable of delivering the required write performance, log-based systems, key-value stores, and other write-optimized data stores have emerged recently. However, the drawbacks of these systems are a fair query performance and the lack of suitable instant recovery mechanisms in case of system failures.
In this article, we present ChronicleDB, a novel database system with a storage layout tailored for high write performance under fluctuating data rates and powerful indexing capabilities to support a variety of queries. In addition, ChronicleDB offers low-cost fault tolerance and instant recovery within milliseconds. Unlike previous work, ChronicleDB is designed either as a serverless library to be tightly integrated in an application or as a standalone database server. Our results of an experimental evaluation with real and synthetic data reveal that ChronicleDB clearly outperforms competing systems with respect to both write and query performance.
