Published: August 2023

AbstractCompetence to combat corrosion of steel‐reinforced concrete (SRC) infrastructures for long periods has become a fascinating topic for corrosion scientists. The longevity of such infrastructures is limited mainly by the corrosion process. Hence, urgent demands for developing effective and practical methods are necessary to minimize the corrosion of such concrete structures. The anti‐corrosive components can be designed from the green plants' parts to mitigate the SRC corrosion in recent years. The ongoing research aims to substantiate the success of the leaf extract of Psidium guajava (LEPG) and its 50% blend (BnD) with the leaf extract of Mangifera indica (LEMI) for assessing the steel corrosion condition in a concrete slab. For this purpose, a fast corrosion potential monitoring (CPM) method is applied per the ASTM procedure. Outcomes of the work summarized that the additions of 500–4000 ppm LEPG and its 50% BnD blend have significant corrosion‐inhibiting action. The corrosion potential (ϕcorr) shifts toward a less corrosion‐risk area of the steel bar for 6 months at ambient conditions.

AbstractIntroduction/AimsAnalysis of biofluids, especially cerebrospinal fluid (CSF), is critically important for amyotrophic lateral sclerosis (ALS) research. Collection of CSF is typically performed by lumbar puncture (LP). Previous studies have demonstrated the safety of LPs in patients with other neurodegenerative diseases, such as Alzheimer's disease, although there are no published studies of the safety of LPs in patients with ALS. We performed a retrospective analysis of complications resulting from LPs.MethodsThis is a retrospective study of LPs performed between 2015 and 2021 on a total of 233 participants (healthy controls [n = 63], ALS [n = 154], and disease controls [n = 16]) as part of clinical research studies at the Washington University ALS Center. We used bivariate logistical analyses looking for associations between participant characteristics and adverse events (AEs), and likelihood ratio tests were used for significance testing.ResultsWe found an overall AE rate of 21.03%. AEs included headache, back pain, vasovagal syncope, and severe headache requiring epidural blood patch. Participants with ALS were not more likely to experience post‐LP AEs compared to controls (odds ratio [OR] 0.61 [0.32–1.18]). Post‐LP headaches were significantly less likely in participants with ALS (OR 0.36 [0.15–0.83]).DiscussionOur findings demonstrate that LP is a safe procedure for participants with ALS, with a similar or lower rate of AEs than in participants without ALS.

AbstractAimTo identify barriers to conducting and publishing research among nursing faculty members at Shaqra University, Saudi Arabia.DesignA qualitative descriptive design was used.MethodsThis qualitative descriptive study was conducted on 12 nursing faculty members from two nursing colleges at Shaqra University, a public university located in Riyadh region, SA, under the supervision of the Ministry of Education. Data were collected between September and October 2021 using semi‐structured interviews and analysed thematically using content analysis.ResultsThree themes emerged in the study, namely (I) individual/personal barrier, (II) institutional barrier and (III) external factors. Barriers to conducting and publishing research included lack of time due to a high teaching load and lack of administrative and financial support. The present findings suggest that nursing faculty members in SA are facing many barriers hindering them from carrying out and publishing research activities. Such barriers need to be urgently addressed through different strategies, including allocating facilities and funds for research, motivating faculty members towards research, and ongoing education and training on research.

Published: August 2023

AbstractOrganizational citizenship behavior is argued to be particularly important to civil society organizations (Akhtar, Hakeem, & Naeem, 2017). However, organizational citizenship behavior needs further theoretically driven research in the civil society sector, which is the overarching aim of this study which compared two competing models of organizational citizenship behavior within the New Zealand's civil society sector: Organ (1988) and Williams and Anderson (1991) models. Participants were N = 442 employees from 217 civil society organizations in New Zealand. Confirmatory factor analysis tested these two competing measurement models of organizational citizenship behavior. Results suggested employees of civil society organizations tended to perform citizenship behavior in accordance with Organ (1988) structured five‐factor model, independent of their organization. Results are discussed, with a focus on why employees working in New Zealand's civil society sector seem to be more likely to perform Organ (1988) model of organizational citizenship behavior, and practical implications presented.

AbstractTherapeutic resistance is a notable cause of death in patients with ovarian carcinoma. Polyploid giant cancer cells (PGCCs), commonly arising in tumor tissues following chemotherapy, have recently been considered to contribute to drug resistance. As a type III deacetylase, Sirtuin1 (SIRT1) plays essential roles in the cell cycle, cellular senescence, and drug resistance. Accumulating evidence has suggested that alteration in its subcellular localization via nucleocytoplasmic shuttling is a critical process influencing the functions of SIRT1. However, the roles of SIRT1 subcellular localization in PGCC formation and subsequent senescence escape remain unclear. In this study, we compared the differences in the polyploid cell population and senescence state of PGCCs following paclitaxel treatment between tumor cells overexpressing wild‐type SIRT1 (WT SIRT1) and those expressing nuclear localization sequence (NLS)‐mutated SIRT1 (SIRT1NLSmt). We investigated the involvement of cytoplasmic SIRT1 in biological processes and signaling pathways, including the cell cycle and cellular senescence, in ovarian carcinoma cells' response to paclitaxel treatment. We found that the SIRT1NLSmt tumor cell population contained more polyploid cells and fewer senescent PGCCs than the SIRT1‐overexpressing tumor cell population. Comparative proteomic analyses using co‐immunoprecipitation (Co‐IP) combined with liquid chromatography–mass spectrometry (LC‐MS)/MS showed the differences in the differentially expressed proteins related to PGCC formation, cell growth, and death, including CDK1 and CDK2, between SIRT1NLSmt and SIRT1 cells or PGCCs. Our results suggested that ovarian carcinoma cells utilize polyploidy formation as a survival mechanism during exposure to paclitaxel‐based treatment via the effect of cytoplasmic SIRT1 on PGCC formation and survival, thereby boosting paclitaxel resistance. © 2023 The Pathological Society of Great Britain and Ireland.

Published: August 2023

AbstractIn this work, an I‐optimal response surface model was used to systematically investigate the effects of graphene (Gr) content (Factor A; 0–10 wt%), temperature (Factor B; 0–200°C), and Gr layer structure (Factor C; monolayer versus five‐layer) on the thermal conductivities of PEI/Gr nanocomposites, which were determined using reverse non‐equilibrium molecular dynamics (RNEMD) simulation with the Müller‐Plathe algorithm. Based on a reduced quadratic model that was fit to the data, the effect of Factor A on thermal conductivity was found to be more pronounced for the PEI/Gr nanocomposite with the five‐layer Gr structure. Moreover, Factor B had expectedly the largest effect on thermal conductivity, followed by Factor C. However, these two factors were involved in significant interactions with Factor A. Based on numerical optimizations, the predicted thermal conductivities of the PEI/Gr nanocomposites varied from 0.057 (minimum) to 0.174 W m−1 K−1 (maximum). Overall, the maximum thermal conductivity of the PEI/Gr nanocomposite may be obtained at any given temperature in the range of 0–200°C by the addition of multi‐layer Gr (a cheaper alternative to monolayer Gr) at a content of 10 wt%. For example, the addition of 10 wt% five‐layer Gr to PEI at room temperature (25°) results yields an increase in its thermal conductivity of about 30%. Also, going from 0 to 100°C, an increase of about 76% is predicted for the thermal conductivity of the PEI/Gr nanocomposite containing 10 wt% five‐layer Gr. The results of this study shed light on the interactions between the three investigated factors.Highlights

AbstractThe present work provides a facile process route for the syntheses of pyrimidinone‐based benzoxazines by using stoichiometric quantities of pyrimidinone bisphenol (PBU) and paraformaldehyde, which are separately reacted with various types of amines under suitable experimental conditions. The molecular structure, curing characteristics, thermostability, hydrophobic behavior, and dielectric properties were analyzed using appropriate analytical methods. The polymerization temperature (Tp) of monomers such as PBU‐oda, PBU‐cha, PBU‐ffa, PBU‐a, and PBU‐fa was determined by differential scanning calorimetry (DSC), and the Tp values were noted at 205, 198, 203, 218, and 240°C, respectively. The percentage carbon residue at 850°C for poly(PBU‐oda), poly(PBU‐cha), poly(PBU‐ffa), poly(PBU‐a), and poly(PBU‐fa) were analyzed using thermogravimetric analysis (TGA). The water interface angle values for poly(PBU‐oda), poly(PBU‐cha), poly(PBU‐ffa), poly(PBU‐a), and poly(PBU‐fa) was found to be 141°, 134°, 142°, 136°, and 142°, respectively. The results from the dielectric studies indicate that the benzoxazines (PBU‐ffa and PBU‐a) composites reinforced with palm flower silica (PF‐SiO2) and boron nitride‐g‐C3N4 (BN‐g‐C3N4) were found to be suitable for low and high dielectric applications. From these diverse studies, it can be determined that pyrimidinone‐based benzoxazines to be utilized as high‐performance products in the form of encapsulants, potting agents, and composites for automotive and microprocessor applications.Highlights

AbstractThe new form of renewable energy attracts enormous attention from researchers for its immense importance and impact on our daily life. A fossil energy is a non‐renewable source that will end shortly because of its immense use in houses and industries. Among the renewable sources, solar cells based on perovskite (PVK) materials exponentially increase their efficiency from 3.8% to 25.8% rapidly in a diminutive period of time. In the present study, doped and undoped PVK layers (MAPbI3, MAPb[I1‐xClx]3) are considered and optimized for solar cell application by using the SCAPS‐1D device simulator. A detailed investigation is done in terms of PVK absorber layer (PAL) thickness variation with different electron and hole transport layers, temperature, and bulk defect density to optimize the device performance. The MAPb(I1‐xClx)3‐based device delivered the highest conversion efficiency of ~29% with JSC of 25.59 mA/cm2, VOC of 1.348 Volt, and an FF of about 83.68%. Results reported in this work may pave the way for the development of advanced high‐efficiency PVK solar cells.
The psychosocial experiences of head and neck cancer caregivers following (chemo)radiotherapy: A systematic qualitative review and narrative synthesis

Published: August 2023

AbstractObjectiveOropharyngeal cancer, a type of head and neck cancer (HNC), the incidence of which is increasing, often affects younger patients than traditional HNC, having distinct psychosocial consequences. Treatment side effects mean many rely on informal caregivers following (chemo)radiotherapy. The purpose of this review was to describe current understanding of the psychosocial experiences of these caregivers in the post‐treatment phase.MethodsA systematic search for relevant studies between January 2010 and October 2022 in three electronic databases (CINAHL, MEDLINE and PsycINFO) was followed by citation searching. Inclusion criteria were developed to ensure studies explored caregivers' experiences during the post‐treatment phase following oropharyngeal cancer (chemo)radiotherapy. Thematic analysis informed by the ‘Cancer Family Caregiving Experience Model’, identified stressors, appraisals and responses. Themes evolved through the synthesis of recurrent concepts across the studies and a narrative of psychosocial experiences and their impact upon caregiver well‐being was developed.ResultsFifteen HNC papers which included exploration of the psychosocial experiences of oropharyngeal cancer caregivers following (chemo)radiotherapy were selected. Findings were synthesised to develop five themes: an emotional struggle, supporting nutrition, altered lifestyles, changes within relationships and support needs.ConclusionsThe completion of (chemo)radiotherapy signalled a transition for these caregivers as they undertook burdensome responsibilities. Experiences indicated that preparation for the role, assessment of needs, and targeted support is required. Additionally, caregivers' recognition by healthcare professionals as caring partners could help moderate this demanding experience.

Published: August 2023

AbstractA simple stochastic representation of the spatial variability in thaw depth is proposed. Thaw depth distribution measured in the two larch‐type forests in eastern Siberia, Spasskaya Pad and Elgeeii, showed different spatial, seasonal, and interannual variability, respectively. Year‐to‐year variation in active‐layer thickness was minor in Spasskaya Pad compared to Elgeeii. A gamma distribution adequately represented both sites' thaw depth spatial variability as the cumulative probability. Thus, we developed a simple model using the gamma distribution that illustrates the spatial variability in thaw depth at any thawing stage as a function of a given mean thaw depth. A hierarchy of models was introduced that sequentially considered the constant state, linearity, and nonlinearity in the dependence of the rate parameter of the gamma distribution on the mean thaw depth. Although the requirements of the model levels differed between Spasskaya Pad and Elgeeii, the proposed model successfully represented the spatial variability in thaw depth at both sites during different thaw seasons.

Contrasting the evolution of radiation fog over a heterogeneous region in southwest France during the SOFOG3D campaign
Authors: Thornton J. , Price J. D. , Burnet F. , Lac C. 
Published: August 2023

AbstractObservations made during the recent SOuth‐west FOGs 3D experiment (SOFOG3D) have been used to investigate the formation and evolution of radiation fog over heterogeneous forest plantations. The focus was on comparing measurements made at a relatively open site on arable land with those made in an approximately 700‐m diameter field surrounded by tree plantations, with both sites hosting an instrumented 50‐m mast. These data showed that at the more sheltered site radiation fog tended to form earlier than at the more open site. This coincided with more rapid decreases and lower minima in both near‐surface temperatures and vertical turbulence from the late afternoon. It is proposed here that the surrounding forest creates a sheltering effect, which can cause a reduction in vertical turbulence and therefore the mixing of cool near‐surface air with warmer air aloft. The near‐surface region is therefore able to cool rapidly, enabling fog to form more readily. Data from additional sites with varying surroundings supported the findings that the more sheltered sites tended to exhibit lower near‐surface nocturnal temperatures. However, the onset of fog formation observed at these additional sites suggested that there could be a limit to how sheltered a site may be before fog formation is inhibited rather than enabled by the surroundings.
Influencing factors associated with the second dominant pattern of the Indian summer monsoon
Authors: Yadav Ramesh Kumar 
Published: August 2023

AbstractThe interannual variation of the Indian summer monsoon (ISM) affects millions of people in India and the global weather and climate. The teleconnections that affect this variation are not stable. The recent four decades of the second dominant mode of ISM rainfall show a unique north–south tripole pattern, with above‐normal rainfall in the north and peninsular India sandwiching suppressed rainfall in central‐east India. The pattern relates to extending the Indo‐Pacific warm‐pool's warmer sea‐surface temperature (SST) towards the south of the equatorial eastern Indian Ocean. Most of the time, this warming and the extension of the warm‐pool's warmer SST are associated with La Niña events, which activate more in situ vigorous convection. The Rossby‐gyres generated west of the equatorial heating increase the tropospheric height over north India, shifting and strengthening the Tibetan High northwards, facilitating heavy rainfall in the north. Meanwhile, the more vigorous convection south of the equatorial eastern Indian Ocean produces compensatory subsidence over central‐east India, suppressing rainfall. The northern hemispheric Rossby‐gyres brings anomalous cyclonic circulation over peninsular India, producing excess rainfall. Also, the dipole pressure anomaly between the northwest Pacific and south tropical Indian Ocean generates anomalous lower‐level easterly winds over the Bay of Bengal. It supplies excess moisture to the north India convections. The co‐occurrence of the active Atlantic intertropical convergence zone supports this tripole rainfall pattern. This teleconnection could further be examined in climate models.
Spatially variable effects of streamflow on water temperature and thermal sensitivity within a salmon‐bearing watershed in interior British Columbia, Canada

Published: August 2023

AbstractWarming temperatures can have negative consequences for aquatic organisms, especially cold‐adapted fishes such as Pacific salmon. The magnitude of warming is related to the thermal sensitivity of streams in salmon‐bearing watersheds (i.e., change in stream temperature for every 1°C increase in air temperature), which can vary based on several factors including streamflow. Management actions to increase streamflow may therefore benefit salmon by decreasing thermal sensitivity. However, the effects of streamflow on thermal sensitivity are often complex, as the temperature of flow inputs can directly increase or decrease temperatures. This study aimed to disentangle the influence of streamflow on thermal sensitivity and stream temperature over 4 years in the Nicola River, a regulated semiarid watershed in south‐central British Columbia, Canada. A statistical modeling approach was used to estimate streamflow effects on stream temperatures and thermal sensitivity (i.e., relationship of regional air temperature to stream temperature) at 12 sites from 2018 to 2021. Streamflow had a variable influence on stream temperatures across the watershed via both direct effects and by modulating thermal sensitivity. At a given site, streamflow was generally negatively associated with summer daily mean stream temperature, but the magnitude of its influence varied among locations and years. The influence of streamflow on thermal sensitivity was also highly variable both spatially and temporally. The analysis suggests that there may be complex relationships between streamflow, stream temperature, and thermal sensitivity, which complicates the efficacy of flow as a lever to mitigate high temperatures in regulated systems.
