The fatigue crack growth behavior of hydrogenated 9Cr‐1Mo steel: An experimental and numerical study
Authors: Bharati Mahesh , Maity Rathin , Singh Akhilendra , Paul Surajit Kumar 
Published: February 2024

AbstractThis research investigates the fatigue crack evolution in P91 steel through experiments and extended finite element method (XFEM) simulation for as‐received and hydrogenated conditions. Hydrogen pre‐charging is performed using a constant current electrochemical method in 1 M sulfuric acid solution. The study compares the experimental fatigue crack growth rate (FCGR) of hydrogenated and as‐received conditions and employs an XFEM simulation to replicate FCGR. The results of the experiments reveal an increased FCGR in hydrogenated specimens. Fracture surface analysis confirms the co‐occurrence of the “hydrogen‐enhanced localized plasticity” (HELP) and “hydrogen‐enhanced decohesion” (HEDE) mechanism (HELP+HEDE, HEDE>HELP). The simulation results closely align with the experimental findings, validating the model's accuracy. Consequently, these findings are the basis for proposing a damage tolerance approach‐based numerical algorithm. This algorithm allows the prediction of component integrity by considering a known crack length. Furthermore, fracture toughness (KIQ) was experimentally evaluated to enhance the understanding of the material's mechanical properties.
Feeding ecology of two reef‐associated snappers (Lutjanus fulviflamma and L. fulvus): Influence of lunar phase on feeding activity
Authors: Shimose Tamaki 
Published: February 2024

AbstractThe lunar phase is known to influence the spawning activity of some Lutjanus snappers, however, information on its influence on feeding activity is limited. In the present study, diet, feeding habit, and lunar periodicity of feeding activity on two reef‐associated sympatric snappers, blackspot snapper Lutjanus fulviflamma (n = 339) and blacktail snapper L. fulvus (n = 172), were investigated by stomach content analyses in the Yaeyama region (24°N, 124°E), southern Japan. Diets of the two snappers were similar and mainly consumed fishes, crabs, and shrimps. Relative volume of the stomach contents to body weight was compared by season, lunar day, and predator size using a generalized linear model. Larger individuals fed on larger fish prey and tended to show higher stomach fullness for both snappers. Periodic regression revealed that the lunar periodicity of the feeding activity is different between the two Lutjanus snappers. The feeding activity of L. fulviflamma increased around the spring tides of both new and full moons during a single lunar cycle. On the other hand, the feeding activity of L. fulvus increased only before the new moon but decreased before the full moon. Spawning of L. fulvus is known to occur only around the full moon, and enlarged gonads are considered to suppress the feeding activity of the species. Individuals with much stomach contents did not have large gonads for both snappers, and this supports the above supposition. Spawning and feeding activities are closely linked and simultaneous temporal analysis will enable a clearer understanding of the ecological role of these predators.
Geographies of inland waterscapes: Thinking with watery places
Authors: Visentin Francesco , Kaaristo Maarja 
Published: February 2024

AbstractHumans and water have a complex relationship that includes various dimensions such as sociocultural, political, legal and ecological. Considering the ubiquity of water, we need a more holistic perspective to help us see water not as a static entity but rather as one in constant movement, physically and conceptually; acknowledging the interplay between water and humans is essential to understanding societal narratives deeply embedded in places. In this special section, an interdisciplinary group of scholars explore inland waters, taking a water‐centric view instead of a land‐centric one. The special section delves into the emerging hydro‐social connections, diverse forms of expertise, governance models, collective and spontaneous actions, and resilience strategies within the context of inland water bodies, exploring how canals, rivers and wetlands are experienced and represented as places. The papers in this collection show that any form of placemaking should take responsible stewardship of water, embrace its dynamic nature, and present a realistic pathway towards sustainable solutions for present and future water challenges.
Helicobacter pylori antigens as immunomodulators of immune system
Authors: Marzhoseyni Zeynab , Mousavi Mohammad Javad , Ghotloo Somayeh 
Published: February 2024

AbstractHelicobacter pylori (H. pylori) is one of the most prevalent human pathogens and the leading cause of chronic infection in almost half of the population in the world (~59%). The bacterium is a major leading cause of chronic gastritis, gastric and duodenal ulcers, and two type of malignancies, gastric adenocarcinoma and mucosa‐associated lymphoid tissue (MALT) lymphoma. Despite the immune responses mounted by the host, the bacteria are not cleared from the body resulting in a chronic infection accompanied by a chronic inflammation. Herein, a review of the literature discussing H. pylori antigens modulating the immune responses is presented. The mechanisms that are involved in the modulation of innate immune response, include modulation of recognition by pattern recognition receptors (PRRs) such as modulation of recognition by toll like receptors (TLR)4 and TLR5, modulation of phagocytic function, and modulation of phagocytic killing mediated by reactive oxygen species (ROS) and nitric oxide (NO). On the other hands, H. pylori modulates acquired immune response by the induction of tolerogenic dendritic cells (DCs), modulation of apoptosis, induction of regulatory T cells, modulation of T helper (Th)1 response, and modulation of Th17 response.
Gender mainstreaming in the Japan Self‐Defense Forces
Authors: Kawano Hitoshi 
Published: February 2024

AbstractThe issue of “gender integration” within the military organization has long been a major research topic in military sociology. In the last two decades, however, specific topics such as “gender mainstreaming,” “diversity management,” and “diversity and inclusion” have pervaded sociological studies on military organizations. In this article, I examine the current state of gender integration in the Japan Self‐Defense Forces (JSDF), focusing on efforts to promote gender mainstreaming. In particular, following the National Action Plan to implement the United Nations Security Council Resolution 1325 was formulated in 2015, the Ministry of Defense issued the JSDF Female Personnel Empowerment Initiative in 2017, in which previous challenges for career development of female SDF personnel were to be removed by making virtually all job categories available for women including combat pilot, missile boat crew, and tank driver. While the number and ratio of female personnel have increased and their prospects of career development have substantially improved in the last few years, work–life conflict and sexual/power harassment remain to be challenging issues for the retention of female personnel. Due to the deep‐rooted male‐dominant organizational culture of the military organization, further organizational challenges remain for JSDF to shift its overarching human resource management paradigm from “Diversity 1.0” to “Diversity 2.0,” with the strong commitment of top leaders to innovate organizational culture.

AbstractAimThis research aimed to determine the impact of problematic mobile phone use on negative mental health outcomes among nursing students in India, highlighting the necessity for targeted interventions and support mechanisms to enhance the overall well‐being and adaptability of future healthcare professionals.MethodsA cross‐sectional survey was conducted in three randomly selected nursing colleges in South India, employing validated and standardized tools such as the Mobile Phone Problematic Use Scale, Patient Health Questionnaire, Insomnia Severity Index Scale, Satisfaction with Life Scale and Rosenberg Self‐Esteem Scale.ResultsThe study included 402 nursing students with an average age of 20.47 years, revealing a 39% prevalence of severe problematic mobile phone usage. Positive correlations were observed between mobile phone problematic use and age, depression and insomnia. Additionally, strong negative correlations were found between satisfaction with life and self‐esteem. Depression and satisfaction with life served as chain mediators in the impact of self‐esteem on problematic mobile phone use, and both self‐esteem and satisfaction with life negatively predicted problematic mobile phone use.ConclusionThe study highlights a prevalent issue of problematic mobile phone use among nursing students, indicating a pressing need for timely intervention, as it correlates with depression, sleep insomnia, low self‐esteem and life dissatisfaction.

Published: February 2024

ObjectivesThis work aims to assess the diagnostic value of chromogranin A (CgA) in the laboratory diagnosis of neuroendocrine tumors classified as pheochromocytoma and paraganglioma (PPGL).MethodsA comprehensive search was performed in PubMed, Embase, the Cochrane Library, and Web of Science databases to obtain relevant studies reporting the diagnostic accuracy of CgA in patients with PPGL. The search involved studies written in English between the time of library inception and May 1, 2023. We computed the pooled sensitivity, specificity, and diagnostic odds ratio (DOR). Additionally, the receiver operating characteristic curve and area under the curve (AUC) were determined. The heterogeneity was assessed using the Chi‐square test and the I2 test. The subgroup analyses were performed to investigate the origins of heterogeneity. Stata 15.1 statistical software was used in all data analyses.ResultsThis meta‐analysis included 13 studies involving 1470 patients. CgA had a pooled diagnostic sensitivity of 0.86 (95% CI 0.81–0.91), a specificity of 0.90 (95% CI 0.81–0.95), and a DOR of 57 (95% CI 23–142). CgA had an AUC of 0.93. The studies did not reveal any threshold effect (r = −0.165; p > 0.05). The subgroup analyses revealed that the control group category and the detection method caused the overall heterogeneity.ConclusionsOur study suggests that CgA is a helpful PPGL biomarker. However, relying solely on CgA for diagnosis is not advisable. A comprehensive approach is essential for accurate diagnosis. Future large‐scale research is needed to refine CgA's clinical application.
New spinel‐structured high‐entropy oxides with high‐ and stable‐infrared radiation properties
Authors: Wan Qifa , Zhang Faming , Xiong Yifeng 
Published: February 2024

AbstractSpinel‐structured high‐entropy oxides (HEOs), the novel materials, have recently attracted great attention for their unexpected properties and extensive applications. In this work, employing a facile scalability process of solid‐state reaction method, we synthesized a new kind of non‐equimolar (Co2/11Mn2/11Fe2/11Cr2/11Ni2/11Cu1/11)3O4 HEOs powder. However, under the same condition, the raw mixed oxide powders, with equimolar cations and higher configuration entropy, cannot form single‐phase HEOs powder but with the mixture of (Co,Mn,Fe,Cr,Ni,Cu)3O4 and residual CuO powders, ruling out the crucial role of entropy effect in forming single‐phase spinel‐structured HEOs. In addition to (Co2/11Mn2/11Fe2/11Cr2/11Ni2/11Cu1/11)3O4 powder, various (Co,Mn,Fe,Cr,Ni,Cu)3O4 HEOs powders can be obtained by controlling the Cu cation content in an appropriate range. To explore the application of the spinel‐structured HEOs in high‐temperature infrared field, the infrared radiation properties of the (Co2/11Mn2/11Fe2/11Cr2/11Ni2/11Cu1/11)3O4 powder were evaluated and exhibited a high‐infrared radiation emissivity of 0.880 in the near‐infrared wavelength range (0.78–2.5 µm) and superior thermal stability. Notably, the infrared radiation emissivity of the HEOs powder was maintained at 0.855 with a slight loss of 2.8% after high‐temperature treatment. This work not only provides a valuable strategy for fabricating high‐ and stable‐infrared radiation properties materials but also expands the great potential application of spinel‐structured HEOs to high‐temperature infrared field, such as energy saving in industrial high‐temperature furnaces.

AbstractBackgroundNHS England's Transforming Care agenda aims to reduce the number of adults with intellectual disabilities and autistic adults in mental health hospitals. The aim was to understand the demographic and clinical characteristics of those most at risk of admission.MethodA cohort, retrospective study of adults using community intellectual disability services in the North West of England from 2018 to 2022 was undertaken.ResultsWe compared 211 adults at imminent risk of admission to a mental health hospital and 249 at significant (but not imminent) risk on a validated risk stratification tool. Individuals at significant risk were more likely to have moderate intellectual disability. Individuals at imminent risk were more likely to have diagnoses of mild intellectual disability, autism, personality disorder, or psychosis.ConclusionBy furthering our understanding of the clinical characteristics of those most at risk of admission, the findings inform more appropriate targeting of resources.

AbstractIn this study, the effect of the cyclone body height on the flow field within the specific cyclone and also on the performance parameters of the cyclone has been investigated. The five heights of the cyclone as various configurations were I = 600, II = 675, III = 750, IV = 825, and V = 900 mm. A pressure‐based solver was used and the turbulent Reynolds stress model was utilized to simulate the flow. Then, the Lagrangian discrete phase model was used to simulate the solid phase. As the height of the cyclone increases, the pressure drop decreases. Also, the best separation efficiency and the highest particle velocity value were achieved at a height of 750 mm. The maximum values of turbulence intensity, skin friction coefficient, and strain rate were obtained as negative components of cyclone performance at the cyclone body height of 900 mm. The height of 750 mm was recognized as the best height of the cyclone's body.Practical ApplicationsApplying numerical simulation in food processing is a novel method to minimize equipment construction and reach a high‐accuracy design. Computational fluid dynamics can provide an accurate and detailed flow analysis in the cyclone separators utilized in the flour processing plant. The dimensional analysis can help the researchers to achieve the optimum design and enhance the cyclone performance by reducing pressure drop and increasing separation efficiency. Also, the maintenance cost would be significantly reduced due to detecting the critical sections and strengthening them.

Published: February 2024

AbstractThis research demonstrates pressurized liquid extraction (PLE) in an intermittent process in obtaining soybean oil using less solvent than conventional extraction. Temperature (T), solvent rinse volume (VS), contact time between the solvent and the matrix (St) in each cycle and number of cycles (C) were screened. Yield, fatty acids profile (FAs), and triacylglycerols were evaluated. After preliminary testing, T and St were tested for yield while VS, C, and P were fixed at 60% of total volume of the fixed bed extractor, 3 cycles, and 10.34 MPa respectively. The highest oil recoveries were 94.40% (85°C, 13 min, with hexane) and 86.16% (80°C, 12 min, with ethanol). The mass ratio of solvent/feeds resulted in a yield increase of 1.47% (hexane) and 3.99% (ethanol). The concentration of β‐sitosterol (≤182.78 mg/100 g of oil, hexane; ≤71.64 mg/100 g of oil, ethanol) and the fatty acid profile were not affected by the different solvents or process. The main fatty acids were linoleic (≤51.12%, ethanol; ≤40.31%, hexane) and oleic (≤24.98%, ethanol; ≤26.62%, hexane). The main triacylglycerols identified were LLO, LLL, and OOL. The results indicate that soybean oil can be obtained by a new process that uses a safe and renewable solvent, indicating that PLE in an intermittent process can replace conventional extraction without changing the main characteristics of the oil, with good yield using less solvent.Practical applicationsThe practical application of this research is related to the possibility of demonstrating the feasibility of PLE in obtaining soybean oil using pressurized ethanol. The solvent used in most oilseed extraction plants is commercial hexane, a toxic and non‐renewable solvent. The experiments were carried out with pressurized hexane to demonstrate the economy of solvents and compare with the results obtained when pressurized ethanol was used as a solvent. The ethanol study aimed to show high extraction yields, even using a polar solvent in soybean oil extraction. High yields and oil characterization showed that it is possible to use a green and clean technology to obtain vegetable oils.

Published: February 2024

AbstractAims and ObjectivesThe aim of this study was to explore the association between transition shocks and professional identity and the mediating roles of self‐efficacy and resilience among Chinese novice nurses.BackgroundNovice nurses experience transition shock when they start their careers, which might lead to decreased professional identity and ultimately turnover. By contrast, self‐efficacy and resilience are excellent psychological resources that may be associated with higher professional identity. It is unclear how transition shock affects professional identity by influencing these two internal resources.DesignA cross‐sectional survey.MethodsThe STROBE guidelines were followed to report this study. Convenience sampling was used to recruit participants, and 252 novice nurses completed the Transition Shock of Novice Nurses Scale, the Professional Identity Assessment Scale, the General Self‐Efficacy Scale and the Connor‐Davidson Resilience Scale between April 2022 and May 2022. Influencing factors were primarily identified using independent‐sample t‐tests and a one‐way ANOVA. Structural equation modelling was used to detect the mediating effects of self‐efficacy and resilience.ResultsDifferences in novice nurses' levels of professional identity were found across age groups, hospitals and departments. Transition shock was negatively related to professional identity. Self‐efficacy and resilience mediated the complete chain relationship between transition shock and professional identity.ConclusionTo our knowledge, this study is the first to explore the mediating effect of self‐efficacy and resilience on transition shock and professional identity. Higher transition shock may lead to lower professional identity by reducing self‐efficacy and resilience.Relevance to Clinical PracticeNursing managers ought to emphasise the significant role of psychological resources in the work adaptation process of novice nurses. It may be more effective to improve professional identity and maintain the stability of the health care system.Patient or Public ContributionNursing administrators working at seven preselected hospitals actively assisted us in the process of collecting self‐report questionnaires from novice nurses, such as by booking appointments and providing access for questionnaire administration. In addition, the participants were actively involved in the data collection process.

AbstractBackgroundPeritonitis is a common and serious complication of peritoneal dialysis and is one of the main causes of peritoneal dialysis technique failure and long‐term hemodialysis conversion.ObjectivesThe aim of the review was to identify and clarify peritonitis risk factors and learn about strategies employed at international level to prevent and reduce the occurrence of peritoneal dialysis associated infections and their complications.DesignA scoping review.ParticipantsAdults in pertitoneal dialysis.MeasurementsThe methodology framework of Arksey and O'Malley and PRISMA for Scoping Reviews guidelines were applied. A search was conducted of PubMed, Scopus and CINAHL using terms to identify peritoneal dialysis ‐associated risk factors and interventions carried out for the prevention and reduction of peritonitis in adult persons living at home.ResultsThe 17 studies selected were based on work carried out in nine different countries. Eleven articles analysed modifiable risk factors (low educational level, being a foreigner and low adherence to aseptic technique) and non‐modifiable risk factors (age and comorbidities) that predispose to peritonitis in peritoneal dialysis. The other six studies applied an intervention to improve the prevalence of peritonitis considering educational practices adapted to patient characteristics and the application of retraining.ConclusionsPersonalised patient training and the identification of risk factors for peritonitis are key to reducing complications and enhancing the survival of peritoneal dialysis patients and the effectiveness of the technique.
