Authors: St-Onge Sylvie , Haines III Victor Y. , Ballesteros-Leiva Felix , Poilpot-Rocaboy Gwénaëlle 
Published: September 2020

PurposeBased on the conservation of resources (COR) theory (Hobfoll, 1989, 2002), this study first investigates the direct influence of core self-evaluations (CSEs) on work-to-family (W → F) and family-to-work (F → W) conflicts. Second, it tests the mediating impact of Social support from work and home domains in the associations between CSEs and both directions of work-family conflict. This study finally examines the moderating influence of CSEs in the associations between work and home domain social support and both directions of work-family conflict.Design/methodology/approachHuman resources professionals (629), and engineers (169) employed in Canada completed an online survey. Both directions of work-family conflict were measured as well as CSEs, and work and home domain social support.FindingsResults indicate that higher CSEs are associated with lower W → F and F → W conflicts. They also suggest an indirect association between CSEs and W → F conflict through supervisor support. The indirect association between CSEs and F → W conflict through home domain social support was also supported. Besides, it appears that CSEs moderate the association between home support and F → W conflict.Research limitations/implicationsOur findings underscore the relevance of considering both dispositional and environmental factors together in work-life research. Results question within- vs. cross-domain conceptualizations of work-life spillover. They also indicate how both differential choice and effectiveness operate in conjunction with managing work-life domains.Originality/valueThe research presents a comprehensive model linking work-family conflict, social support and CSEs. It draws from an integrative personality framework (Judge et al., 1998) and COR theory (Hobfoll, 1989) to explore the underlying processes of CSEs, often inferred but not specified or incorporated into work-life research.

Published: September 2020

AimTo critically appraise and synthesize evidence of integrated care stemming from advanced practice nursing in elderly primary care settings throughout the United States and Thailand.BackgroundAdvanced practice nurses are key to accelerating integrated elderly care in the community. Yet, their scope and capacity vary greatly across countries, making impact measurement highly challenging.MethodsA systematic search of PubMed, CINAHL, Scopus and ThaiJo databases was performed. Full‐text articles in English or Thai language were reviewed using an inductive thematic approach from the integrated people‐centred Health Services framework, adopted by the World Health Organization.ResultsA total of 42 articles were appraised according to framework strategies: (1) people and community empowerment/engagement; (2) governance and accountability strengthening; (3) model of care reorientation; (4) service coordination; and (5) enabling environment creation. Collaborative roles and empowerment of older people were associated with higher quality of care. Thai nurses empowered individuals through community networks and resources, incorporating care models (strategy 1). In contrast, US nurses adopted a quality improvement and safety approach, incorporating technology into nursing interventions (strategy 5).ConclusionAdvanced practice nurses employ an array of strategies and approaches in caring for older people. Although their role varies from mostly substitute (US) to supplemental (Thailand), nurses in both countries contribute towards integrated person‐centred care.Implication for nursing practice and nursing policyPreparing advanced practice nurses to work in the community is a prerequisite for meeting ageing population health needs in a sustainable manner. Education, professional development and leadership training opportunities should focus on capacity building in: a) strengthening mutual accountability, b) reorienting the work environment through innovative care models and c) coordinating services through partnerships to achieve universal health and ensure healthy ageing.

ObjectivesA series of constant anatomical structures were used as guide targets for screw placement to improve the accuracy of cortical screw placement and reduce surgical injury and fluoroscopy radiation. The most commonly used angles and distances between the cortical bone screw insertion point and the lateral margins of the isthmus were selected as the contents of the questionnaire.MethodsA total of 40 physicians were selected to determine the specific values for each angle and distance. Screw placements were performed on four dry and six wet lumbar spine specimens according to the proposed anatomical target guidance technique. A total of 100 cortical bone trajectories were evaluated using X‐ray and CT scanning of the specimens to verify the practicability, accuracy, and safety of the anatomical target guidance technique in screw placement.ResultsThe average deviation rates for angle and distance determination were 105.5% and 14.33%, respectively, indicating a significant difference between the estimated and actual values from other angles (P < 0.05). Based on visual inspection, probe penetration, X‐ray, and CT examination of 100 cortical bone trajectories, the excellent rate of 40 trajectories on four dry specimens was 95%, while that of 60 trajectories on six wet specimens was 88.7%.ConclusionUse of lumbar constant anatomical structures as targeting guidance could assist cortical bone screw placement and reduce surgical damage.

Published: September 2020

Abstract
Urban central heating network (UCHN) is an important infrastructure in northern China. However, as the technology and management of heating operators are still at a low level, a lot of energy is wasted in heating network. Based on the actual operation data of nearly 100 heating stations in northern China in 2018–2019 heating seasons, this study comprehensively analyzes the problems existing in the operation of UCHN in China from the perspective of time and space, investigating the correlation between the hourly energy consumption of a single thermal station and the hourly outdoor temperature in the time dimension and examining the uniformity of heat supply of different thermal stations in the space dimension. This paper focuses on the analysis of the heat consumption per unit area (HCA), temperature of primary side return water (TPSRW), heat consumption per unit area per unit temperature difference (HCATD) and its standard deviation (SHCATD) of each heating station in the early, middle and end period of heating season. The results show that the TPSRW among different thermal stations varies greatly and distributes unevenly, suggesting that the problem of thermal imbalance is serious. The SHCATD in these two periods is dramatically higher than that in the middle period, indicating that the control systems of current heating systems fail to compensate for the weather. Two measures are proposed to solve the problems of the operation of UCHN.

Published: September 2020

Abstract
The following paper aims to explore a heat pump’s (HP) as well as an organic Rankine cycle’s (ORC) novel combination for the development of both an efficient and low-emissions heating and cooling systems. This latest review examines both benefits and possibilities of a combined HP-ORC system. Previously, studies have explored several different combinations, such as directly-coupled and reversible combination units as well as parallel configurations units in addition to indirectly-coupled ones. Following defining aforementioned configurations, a discussion on their performance is carried out in detail. Considerations for the optimisation of the architecture, overall of such hybrid systems via utilising the same sources while also discussing heat source, sink selection and operating temperatures as well as thermal energy storage, expander/compressor units, control strategies in addition to working fluids’ selection and managing seasonal temperatures that are increasingly variable, have been identified. Additionally, the experimental studies that have been performed reveal increasingly practical obstacles as well as other areas that require more research while serving to shed light on experimental techniques, which can be applicable to this research’s area.
Based upon research, it has been revealed that regional conditions including temperatures and annual weather as well as the cost of energy produce a colossal effect on such systems’ economic feasibility framework as well as partially dictating the overall system configuration’s selection. Additionally, the review disclosed how important the following elements are: 1) a greater temperature differential amid the source of heat and heat sink; 2) proper source of heat and sink selection; 3) working fluid selection; and 4) thermal storage for the maintenance of the difference. Comparatively, from the research works from the past, additional optimisation based on individual component level as well as through control strategies of either an advanced or predictive method, these produce a smaller effect and are worth performing an evaluation on economically due to them not being feasible for the current system.
Lastly, based on investigated research, there are certain areas for which recommendation have been provided with regard to future research and this includes a technology configurations’ comparison for understanding different regions’ optimal system, a sensitivity analysis for understanding key system elements for both optimisation as well as design, both an investigation as well as testing carried out for available units and applicable systems that are presently available, and identifying novel use cases.

Abstract
This paper presents a study on the effects of transient and steady-state vehicle operation on fuel economy and emissions trends of an in-use Euro 2 Asian utility vehicle in the Philippines, with a normally aspirated direct-injection engine, and fueled with different CME-diesel blends designated as B1, B2, B3, B5, B10, B20, B50, & B100 corresponding to increasing CME percentage blends. The vehicle was driven on a chassis dynamometer following the Japanese 10-15 Mode drive cycle and at steady speeds of 40, 60, & 80 kph for fuel consumption and CO, NOx, and THC measurements. PM measurements were not undertaken.
Drive cycle results showed that adding CME up to 20% by volume (B20) has a small effect on the heating values, specific fuel consumption (SFC), fuel economy (FE), and maximum power. Relative to neat diesel, the increase in SFC, lower FE and power beyond B20 were attributed to lower heating values at higher blends. CO was practically constant while THC and NOx generally decreased with increasing CME blends. The CO and THC trends were ascribed to overall lean mixtures and increased amount of oxygenated fuel at higher CME blends. B20 yielded the most emissions reduction without performance loss.
Steady speed results indicated for all blends, SFC increased with vehicle speed due to higher road load. Above B10, SFC went beyond 5% higher than that for neat diesel and is attributed to lowered heating values of higher blends. The SFC of blends up to B10 approached that of neat diesel as speed increased suggesting more diesel-like combustion characteristics. The blend fuel economy showed an inverse relationship to SFC as expected. Both CO and NOx exhibited slightly decreasing trends with higher blends at all speeds. For a given blend, CO decreased while NOx increased as speed went higher. THC followed bowl-shaped trendlines with blend ratio. THC was high for neat diesel going lowest at B5-B10 and upwards again beyond B10. For a given blend, THC emissions decreased with increasing vehicle speed.
Design of a 1 MWth Supercritical Carbon Dioxide Primary Heat Exchanger Test System
Authors: Carlson Matthew , Alvarez Francisco 
Published: September 2020

Abstract
Concentrating Solar Power (CSP) plants have the potential to provide dispatchable renewable power generation to support the baseload need currently supplied primarily by coal and nuclear plants and peaking power capability to reduce the use of natural gas for load following. However, these plants have had difficulty achieving widespread use due to the low cost of combined photovoltaic and battery systems capable of providing similar services to the electricity grid. A new generation of CSP technologies must be developed to reduce the levelized cost of electricity (LCOE) to 6 cents/kWh by leveraging heat transfer fluids (HTF) capable of operation at higher temperatures and coupling with higher efficiency power conversion cycles. Three promising pathways for Generation 3 CSP (Gen3CSP) technology development have been funded by the U.S. Department of Energy (DOE) leveraging solid, liquid, and gaseous HTFs to transfer heat to a supercritical carbon dioxide (sCO2) Brayton cycle.
The primary heat exchangers (PHX) necessary to couple these high-temperature HTFs to sCO2 are an essential new technology that must be demonstrated at a scale relevant to commercial CSP to validate design expectations for performance, lifetime, and operability. The demonstration of these PHXs need a reliable 1 MWth-scale sCO2 test system that can provide sCO2 coolant to the PHX in a compact package suitable for installation near any Gen3CSP thermal storage system. This paper outlines the final design of such a system including the expected operating range and off-design capabilities. The system uses a dense-phase high pressure canned motor pump as the sCO2 circulator and ambient air as the ultimate heat sink operating at pressures up to 250 bar and temperatures up to 715 °C with capability to supply up to 5.3 kg/s of sCO2 flow to the primary heat exchanger. Key component requirements for this system have been frozen and procurement is underway. The expected completion date for heated acceptance testing of this system is September of 2020.
This system is also capable of being upgraded through the addition of a turbo-compressor and turbo-generator to operate as a complete sCO2 Brayton cycle with power generation in order to demonstrate an integrated solar to sCO2 power pilot plant and understand transient interactions between the thermal storage system, sCO2 turbomachinery, and ambient air temperature. In addition, this upgrade would provide experience with plant operating considerations including balancing charging the thermal storage system with generating and dispatching power to the electrical grid. A roadmap for this upgrade will be discussed including limitations and requirements for the necessary turbomachinery.

Abstract
The US Department of Energy (DOE) has sponsored an initiative to improve the thermal efficiency of Concentrating Solar Power (CSP) systems. To approach parity with conventional fossil fuel-based electricity generation, the operating temperature of the CSP power cycle must exceed 700°C with integrated thermal energy storage. The materials used to house this high-temperature heat transfer media must be thermally stable and corrosion resistant. However, the temperature-dependent thermophysical properties of commonly used containment materials (nickel alloys and alumina-based firebricks) are either not well known or poorly understood. In this report, the high-temperature thermal properties of thirteen (13) candidate containment materials proposed by the CSP community are tested using laser flash analysis and differential scanning calorimetry.

ObjectiveTo describe neurodevelopment and follow-up services in preschool children with heart disease (HD).DesignSecondary analysis of a prospectively collected multicentre dataset.SettingThree London tertiary cardiac centres.PatientsPreschool children<5 years of age: both inpatients and outpatients.MethodsWe analysed results of Mullen Scales of Early Learning (MSEL) and parental report of follow-up services in a representative convenience sample evaluated between January 2014 and July 2015 within a previous study.ResultsOf 971 preschool children: 577 (59.4%) had ≥1 heart operation, 236 (24.3%) had a known diagnosis linked to developmental delay (DD) (‘known group’) and 130 (13.4%) had history of clinical event linked to DD. On MSEL assessment, 643 (66.2%) had normal development, 181 (18.6%) had borderline scores and 147 (15.1%) had scores indicative of DD. Of 971 children, 609 (62.7%) were not receiving follow-up linked to child development and were more likely to be under these services with a known group diagnosis, history of clinical event linked to DD and DD (defined by MSEL). Of 236 in known group, parents of 77 (32.6%) and of 48 children not in a known group but with DD 29 (60.4%), reported no child development related follow-up. DD defined by MSEL assessment was more likely with a known group and older age at assessment.ConclusionsOur findings indicate that a ‘structured neurodevelopmental follow-up pathway’ in preschool children with HD should be considered for development and evaluation as children get older, with particular focus on those at higher risk.

Background/AimsTo investigate the association between exposure to intraocular pressure (IOP)–lowering medications during pregnancy and neonatal adverse outcomes.MethodsThis retrospective, cohort study used the JMDC Claims Database (JMDC, Tokyo, Japan), 2005–2018. We extracted data on pregnant women with glaucoma, including dispensation of (1) any IOP-lowering medications, (2) only prostaglandin analogues (PGs) and 3) only beta-blockers, during the first trimester. We compared frequency of congenital anomalies (CA), preterm birth (PB), low birth weight (LBW) and the composite outcome of these three measures, between the women with and without IOP-lowering medications. We calculated propensity scores (PSs) using logistic regression in which use of IOP-lowering medications was regressed against known confounders (disorders during pregnancy and other chronic comorbidities). We then conducted logistic regression in which neonatal adverse outcomes were regressed against use of IOP-lowering medications with adjustment for the PS.ResultsWe identified 826 eligible women, 91 (11%) of whom had received any IOP-lowering medications. CA occurred in 9.9% and 6.4%, PB in 2.2% and 4.5%, LBW in 9.9% and 6.0% and composite outcome in 17.6% and 13.3% of mothers with and without IOP-lowering medications, respectively. After adjustment for PS, IOP-lowering medications were not significantly associated with more frequent CA (adjusted OR (aOR), 1.43; 95% CI, 0.66 to 3.12), PB (aOR, 0.45; 95% CI, 0.10 to 1.97), LBW (aOR, 2.11; 95% CI, 0.98 to 4.57) or composite outcome (aOR, 1.40; 95% CI, 0.78 to 2.53). Results were similar regarding PGs only and beta-blockers only.ConclusionsIOP-lowering medications during the first trimester were not significantly associated with increase in CA, PB or LBW.

BackgroundThe ability of deep learning (DL) algorithms to identify eyes with neovascular age-related macular degeneration (nAMD) from optical coherence tomography (OCT) scans has been previously established. We herewith evaluate the ability of a DL model, showing excellent performance on a Korean data set, to generalse onto an American data set despite ethnic differences. In addition, expert graders were surveyed to verify if the DL model was appropriately identifying lesions indicative of nAMD on the OCT scans.MethodsModel development data set—12 247 OCT scans from South Korea; external validation data set—91 509 OCT scans from Washington, USA. In both data sets, normal eyes or eyes with nAMD were included. After internal testing, the algorithm was sent to the University of Washington, USA, for external validation. Area under the receiver operating characteristic curve (AUC) and precision–recall curve (AUPRC) were calculated. For model explanation, saliency maps were generated using Guided GradCAM.ResultsOn external validation, AUC and AUPRC remained high at 0.952 (95% CI 0.942 to 0.962) and 0.891 (95% CI 0.875 to 0.908) at the individual level. Saliency maps showed that in normal OCT scans, the fovea was the main area of interest; in nAMD OCT scans, the appropriate pathological features were areas of model interest. Survey of 10 retina specialists confirmed this.ConclusionOur DL algorithm exhibited high performance for nAMD identification in a Korean population, and generalised well to an ethnically distinct, American population. The model correctly focused on the differences within the macular area to extract features associated with nAMD.
