ABSTRACTAimTo examine the association between nurses' insomnia, presenteeism and care left undone and explore the mediating effect of presenteeism on the relationship between insomnia and care left undone among nurses in acute care hospitals, applying a dynamic model of presenteeism and absenteeism.DesignA cross‐sectional design.MethodsA secondary data analysis was conducted using online survey data collected in January 2023. Participants were 1154 registered nurses who provided direct nursing care to patients in tertiary or general hospitals (hospitals with 300 or more beds) in South Korea. Poisson regression analysis was used to examine the association between nurses' insomnia, presenteeism and care left undone. Generalised structural equation modelling was performed to examine the mediating effect of presenteeism on the relationship between insomnia and care left undone.ResultsThe prevalence of insomnia was 15.3%. More than half of the participants (63.7%) reported experiencing presenteeism in the past 4 weeks. All reported at least one nursing care left undone during their last shift. Insomnia and presenteeism were positively associated with care left undone, and presenteeism mediated the relationship between insomnia and care left undone among nurses in acute care hospitals.ConclusionNurses experienced insomnia and presenteeism, related to higher rates of care left undone. Nurses' insomnia had a direct effect on care left undone and an indirect effect through presenteeism.Implications for the ProfessionNurse managers and administrators need to make greater efforts to reduce insomnia and presenteeism among nurses, thereby reducing care left undone and improving patient safety in acute care settings.ImpactNurse managers and administrators should consider proactive interventions to address nurses' insomnia and foster a workplace with healthy systems and culture to reduce sleep disturbance and presenteeism, which can effectively decrease care left undone.Reporting MethodSTROBE guidelines.Patient or Public ContributionNo patient or public contribution.

Multidimensional frailty and sleep quality in late adulthood: A UK biobank examination
Authors: Coundouris Sarah P. , Henry Julie D. , Oestreich Lena K. L. 
Published: September 2024

SummaryFrailty and sleep disturbances are two major concerns in late adulthood, that not only profoundly threaten health and wellbeing at the individual level but place enormous demands on our healthcare systems. Given that both constructs represent dynamic states that are preventable and reversible, understanding the potential pathways to and effects of these variables on one another is critical in providing effective and tailored support. However, despite growing interest in the relationship between sleep and frailty, only one study to date has directly explored their potential bidirectionality. Accordingly, this study was designed to extend the current understanding by investigating the reciprocal relationship of frailty and sleep quality at the multidimensional level. Specifically, the bidirectionality of these relationships was considered separately for physical, psychological, cognitive, and social frailty. Four random‐intercept cross‐lagged panel models with three time points were conducted, using 3192 older adults (Mage = 60.21; 46.37% female at baseline) from the UK Biobank. The results revealed that while physical, psychological, and cognitive frailty were neither predictive of, nor predicted by, sleep quality, social frailty and sleep share a reciprocal relationship. These data therefore offer important preliminary evidence for the efficacy of early intervention and prevention strategies aimed at enhancing sleep quality to reduce social frailty, and vice versa.

AbstractCalcium supplementation in pregnancy is recommended in contexts with low dietary calcium intake to reduce the risk of pre‐eclampsia and its complications. The World Health Organisation suggested high‐dose calcium supplementation (1500–2000 mg/day), divided into three doses and taken at different times from daily iron‐folic supplements. We conducted a mixed methods evaluation study to assess experiences, acceptability and barriers to high‐dose calcium supplementation from the perspectives of pregnant women and antenatal health care providers at two public health facilities in Dar es Salaam, Tanzania. Descriptive statistics and thematic analysis were used to characterise acceptability, barriers and overall experiences of using high‐dose calcium supplementation. Pregnant women in the cohort were aged 19–41 years, with 32.4% being primiparous. The proportion of pregnant women who liked calcium supplements ‘a lot’ decreased from 50.2% at the first visit to 31.8% at the last antenatal follow‐up visit. Adherence was 71.3% (interquartile range: 50.5%, 89.3%), with only 24.0% of the participants taking 90% or more of the required supplements. Although participants expressed positive attitudes towards using calcium supplements, they also voiced concerns about the large size, side effects, the potential to forget and the burden of taking calcium supplements three times per day. Antenatal health care providers also affirmed the high burden of taking calcium supplements in addition to iron‐folic acid supplements. Participants expressed the acceptability of using calcium supplements during pregnancy, but adherence to three doses per day posed challenges to pregnant women. Reducing the number of calcium supplement doses per day may improve adherence.
Addendum to ‘Elements of the Philosophy of “Right”’
Authors: Westphal Jonathan 
Published: September 2024

AbstractIn a paper called ‘Elements of the Philosophy of “Right”’ (Philosophical Investigations (2022):1–8), I gave an account of what ‘right’ means, both ethically and generally. I was surprised to find little or no previous work on this topic. I came to the conclusion that the word means the same thing in ethical uses as it does in other non‐ethical uses. However, I have since come to see that there is a seemingly convincing objection to my account, though I stand by the account as given. The objection itself turns out to be a confusion.
Dynamics of ROS production, SOD, POD and CAT activity during stigma maturation and pollination in Nicotiana tabacum and Lilium longiflorum

Published: September 2024

Abstract
Reactive oxygen species (ROS) are a key regulator of physiological processes in pollen grains, and an essential component of stigma exudate. The mechanisms of this redox‐based regulatory system and its features in different plant groups are still unclear.
For two species from different families (tobacco and lily), the dynamics of total ROS, O•2− generation, and H2O2 concentration in stigma exudate were examined using EPR spectroscopy and quantitative colorimetric analysis. Dynamics of all major enzymes of redox homeostasis were analysed using native electrophoresis and zymography for four stages of stigma development, before and after pollination.
There were completely different patterns of ROS production and interconversion in the two species. In tobacco, the initially high level of ROS generation decreased before pollination but remained high. There was no CAT activity in fresh stigma tissues, which apparently contribute to the high level of H2O2. Lilium had peak O•2− generation at the fertile stage and high activity of H2O2‐reducing enzymes, including CAT, hence, H2O2 level remained relatively low.
We suggest that Lilium pollen germination is largely controlled by the SOD radical, while in Nicotiana H2O2 is the main form of ROS in the stigma.

Abstract
This study investigated the effect of mixing volatile organic compounds (VOC) emitted by host and non‐host plants on the orientation of key pests of Brassicaceae. The study aimed to understand how these mixed VOCs influence pest behaviour, which could help in tailoring pest management strategies.
The orientations of flea beetles, Phyllotreta spp., and the diamondback moth (DBM), Plutella xylostella, towards cabbage VOCs mixed with faba bean VOCs were assessed using Y‐tube olfactometry. The pests' preferences were measured to determine if the presence of faba bean alongside cabbage altered their olfactory orientation compared to cabbage alone.
Flea beetles showed a preference for cabbage VOCs alone over the cabbage–faba bean VOC mix. For DBM, no significant preference was observed between cabbage alone and the cabbage–faba bean mix. Previous findings indicated that faba bean attracts DBM, and in this study the mixture of cabbage and faba bean appeared to be more attractive than cabbage alone.
The results indicate that faba bean VOCs can deter flea beetles from cabbage, potentially offering a pest management strategy. However, the effect on DBM was inconclusive, with no clear preference observed. This suggests that while faba bean VOCs may influence pest orientation, their effectiveness varies among different pest species. Additionally, herbivore damage to cabbage leaves did not appear to influence the odour‐guided orientation of either pest, irrespective of the presence or absence of faba bean.

AbstractIt remains unclear whether feedback from group III/IV muscle afferents is of continuous significance for regulating the pulmonary response during prolonged (>5 min), steady‐state exercise. To elucidate the influence of these sensory neurons on hyperpnoea, gas exchange efficiency, arterial oxygenation and acid–base balance during prolonged locomotor exercise, 13 healthy participants (4 females; 21 (3) years, : 46 (8) ml/kg/min) performed consecutive constant‐load cycling bouts at ∼50% (20 min), ∼75% (20 min) and ∼100% (5 min) of with intact (CTRL) and pharmacologically attenuated (lumbar intrathecal fentanyl; FENT) group III/IV muscle afferent feedback from the legs. Pulmonary responses were continuously recorded and arterial blood (radial catheter) periodically collected throughout the exercise. Pulmonary gas exchange efficiency was evaluated using the alveolar‐arterial difference (). There were no differences in any of the variables of interest between conditions before the start of the exercise. Pulmonary ventilation was up to 20% lower across all intensities during FENT compared to CTRL exercise (P < 0.001) and this hypoventilation was accompanied by an up to 10% lower arterial and a 2–4 mmHg higher (both P < 0.001). The exercise‐induced widening of was up to 25% larger during FENT compared to CTRL (P < 0.001). Importantly, the differences developed within the first minute of each stage and persisted, or further increased, throughout the remainder of each bout. These findings reflect a critical and time‐independent significance of feedback from group III/IV leg muscle afferents for continuously regulating the ventilatory response, gas exchange efficiency, arterial oxygenation and acid–base balance during human locomotion.
imageKey points
Feedback from group III/IV leg muscle afferents reflexly contributes to hyperpnoea during short duration (i.e. <5 min) locomotor exercise.
Whether continuous feedback from these sensory neurons is obligatory to ensure adequate pulmonary responses during steady‐state exercise of longer duration remains unknown.
Lumbar intrathecal fentanyl was used to attenuate the central projection of group III/IV leg muscle afferents during prolonged locomotor exercise (i.e. 45 min) at intensities ranging from 50% to 100% of .
Without affecting the metabolic rate, afferent blockade compromised pulmonary ventilation and gas exchange efficiency, consistently impairing arterial oxygenation and facilitating respiratory acidosis throughout exercise.
These findings reflect the time‐independent significance of feedback from group III/IV muscle afferents for regulating exercise hyperpnoea and gas exchange efficiency, and thus for optimizing arterial oxygenation and acid–base balance, during prolonged human locomotion.

Abstract
Electric vehicle (EV) technology has matured over time, improving in some performance areas against traditional internal combustion engine (ICE) vehicles. Despite advancement, there are considerable opportunities for further improvements, particularly in the broader field of lubrication, including areas like grease. As in any mechanical system, greases and lubricants play a significant role in the component life of EV power plants and drivetrains. Moreover, they can significantly contribute to vehicle efficiency, energy savings, and overall driving experience. Since the lubricants in EVs work under harsh thermal and electrical environments, designing an ideal high performance and stable lubricant can be challenging. This article evaluates the industry's progress on EV lubrication including analyzing existing lithium-based lubricants and spotlighting advanced material additives such as graphene, boron nitride, or cutting-edge ionic liquids. It also discusses optimizing base stock selection, with a focus on polyalphaolefin (PAO) molecules and designing various additives to enhance the lubricant's performance, targeting EV applications. This article concludes by exploring the development of nanotechnology and advanced biotechnology for water-based lubricants, promoting efficient lubrication in the electric vehicle sector.

Published: September 2024

Abstract
The stability, combustion, and emission features of stratified oxy-methane (CH4/O2/CO2) flames stabilized over a dual annular counter-rotating swirl (DACRS) burner, developed for gas turbine combustion applications, were investigated experimentally. The experiments were performed at fixed velocity ratio (Vr = Vp/Vs = 3.0) in both the primary and secondary streams at a constant primary stream velocity, Vp of 5 m/s and at fixed primary stream equivalence ratio, φp = 0.9, and over ranges of oxygen fractions (OFp for the primary stream, OFs for the secondary stream) and secondary stream equivalence ratios. Measurements of flame macrostructure, temperature profiles, and exhaust emissions were recorded to characterize the flames and validate future numerical models. The testing findings revealed no flame flashback within the operational ranges of OFp and OFs and up to φs = 1.0. However, the near stoichiometric operation of the primary stream (φp = 0.9) at OFp = 0.38 permitted the main secondary flame to tolerate exceptionally lean conditions (φs = 0.397 at OFs = 0.34 and φs = 0.223 at OFs = 0.39), raising the thresholds for the flame blowout. Increasing OFp from 0.21 to 0.38 significantly reduced φS at blowout from 0.537 to 0.223, corresponding to a decrease in the combustor's global equivalence ratio (φg) at blowout from 0.554 to 0.254 at global oxygen fraction (OFg) from 0.38 to 0.39. Lower OFp values caused earlier flame lift-off, indicating the greater influence of OFp on flame macrostructures.

Abstract
We propose a machine learning-based methodology suitable for use in regions where full availability of meteorological data is lacking. In response to the growing global energy demand and the need to reduce the carbon footprint generated by fossil fuels, solar energy has become the central renewable energy source through small and large-scale photovoltaic systems. Solar energy production depends on the available amount of solar irradiation in a given area, considering the influence of external factors such as environmental conditions, seasons, geographic location, and others. Many regions in the global south do not maintain an updated solar irradiance database, limiting an efficient solar potential analysis. Meteorological stations can provide high-precision ground measurements. However, such stations cover specific locations that cause a spatial data availability problem. This problem can be solved using satellite data, which provides zone-wise spatial information. However, the measurements made by satellites are not as accurate as those obtained on the ground. In this work, we opted for tree-based regression models to map satellite to meteorological stations’ Global Horizontal Irradiation (GHI). Then, we propose using these data generated through regression for GHI forecasting to facilitate applications such as sizing and operating photovoltaic and solar thermal systems. We illustrate this methodology through a case study where we used the generated dataset along with an LSTM neural network showing better performance in forecasting short-term irradiance when compared to an statistical baseline.
Design and Simulation of a Novel and Efficient PVT System: Evacuated Tube Photovoltaic Thermal System

Published: September 2024

Abstract
In single-junction photovoltaic (PV) systems, a large portion of the solar energy is converted to heat and dissipated to the environment as the electrical conversion efficiency of the PV cells is around 20% or less. Also, the electrical efficiency of the PV cells decreases with rise in the surface temperature of the cells. Accordingly, photovoltaic thermal (PVT) systems have been introduced as a hybrid system to extract heat from PV panels and utilize it for domestic hot water, desalination, space heating, etc. In this research, an advanced and novel evacuated tube PVT system has been designed and simulated for highly efficient and sustainable cogeneration of heat and electricity. The PVT system is encapsulated inside an evacuated tube glazing that minimizes the convective heat losses to the environment. At a solar irradiance level of 900 W/m2, the system can deliver hot water with an outlet temperature of 61.8 °C, thermal efficiency of 54.96%, and electrical efficiency of 15.81%. Thermal and electrical performances of the PVT system depend on the solar irradiance level and water outlet temperature, and in most cases, the total efficiency of the system is above 70%.
