AbstractA novel, facile, rapid, and precise synchronous spectrofluorimetric method was evolved for the simultaneous estimation of bisoprolol fumarate and ivabradine in dosage forms and biological fluids. The estimation is based on measuring the first derivative of the synchronous fluorescence spectra of ivabradine and bisoprolol fumarate in ethanol at Δλ = 80 nm. The peak amplitudes are measured at 234.4 nm (zero‐crossing point of ivabradine) and 244.0 nm (zero‐crossing point of bisoprolol fumarate) to simultaneously analyze bisoprolol fumarate and ivabradine, respectively. The spectrofluorimetric method was optimized by investigating different solvent systems, pH values, and surfactants. The proposed method was linear over concentration ranges 30.0–200.0 ng/ml and 30.0–180.0 ng/ml for ivabradine and bisoprolol fumarate, respectively with detection limits of 4.88 and 5.28 ng/ml. The developed method was used for individual assay of the studied compounds in their pharmaceutical dosage forms with high percentage recoveries. Moreover, the method was applied to analyze ivabradine and bisoprolol fumarate in spiked human urine with percentage recoveries of 99.98 ± 1.16 and 99.95 ± 1.96 for ivabradine and bisoprolol fumarate, respectively. The method greenness was also investigated by Analytical GREEnness (AGREE), Analytical Eco‐Scale, and Green Analytical Procedure Index (GAPI) metrics, which ensured the ecofriendship of the proposed method.

AbstractIntroductionThe aim of this article is to determine whether there are differences in the coping strategies of parents of children with disabilities (autism spectrum disorder or other disabilities) and children without disabilities, in reference to the most stressful situation they have experienced with their child in the last year.MethodTo conduct the study, a purposive sample selection based on case‐control characteristics was carried out, in which a total sample of 170 participants was recruited. Participants were assigned, according to their characteristics, to the group of parents of children without disabilities, with ASD or with other disabilities. An ad hoc sociodemographic questionnaire and the Coping Responses Inventory for adults were administered.ResultsThe results obtained indicate that there are differences in the use of coping strategies between parents of children without disabilities and with disabilities but not between the two disability groups. Parents of children with disabilities have significantly higher scores on the four subscales defined as avoidance strategies, and on one subscale identified as an approach strategy.ConclusionsParents of children with disabilities use avoidance strategies, to a greater extent, during the most stressful situations they have experienced in the last year with their child. In addition, they tend to use avoidance strategies regardless of the type of disability their child has.
Corporate environmental investment and supply chain financing: The moderating role of environmental innovation
Authors: Zhu Xuehong , Liu Ran , Chen Jinyu 
Published: July 2022

AbstractUsing microdata from listed Chinese firms for 2009–2019, we examined whether and how corporate environmental investments affect supply chain financing. We further investigated the moderating effect of two types of environmental innovation (i.e., voluntary versus compliance environmental innovations). The findings revealed that firms with high levels of environmental investments were more inclined to obtain supply chain financing. This evidence suggests the positive effects of supply chain stakeholders in promoting corporate environmental governance. Moreover, the association could be more or less pronounced for firms with high levels of compliance or voluntary environmental innovation, respectively. Furthermore, channel tests indicated that social responsibility and transaction trust were the primary channels for explaining the above relationships. Finally, the positive relationship between environmental investment and supply chain financing only held for firms located in different cities from the supply chain firms and firms with high social attention. These findings highlight the heterogeneous role of environmental innovation and public governance in alleviating firms' financing constraints.

Published: July 2022

AbstractTuberculosis (TB)‐related death has increased for the first time in a decade due to the coronavirus disease 2019 (COVID‐19), globally. People living with HIV (PLWHIV) might be at a higher risk of developing COVID‐19‐related complications. Herein, we describe the first case of a patient surviving from SARS‐CoV‐2‐TB‐HIV triple co‐infection in Cameroon. A 36‐year‐old Cameroonian woman presented at the emergency unit of the Jamot Hospital, Yaoundé with symptoms of anorexia, productive cough, weight loss, and fever. The SARS‐CoV‐2 rapid antigen test on nasopharyngeal sample was positive. Chest X‐ray showed bilateral parenchymal and tracheal calcifications most consistent with prior pulmonary histoplasmosis, varicella, or TB. She was tested HIV positive, and the sputum sample tested positive for TB on auramine staining. TB therapy (rifampicin, isoniazid, pyrazinamide, and ethambutol) and COVID‐19 treatment were initiated, and the symptoms improved after 2 weeks of treatment. The SARS‐CoV‐2 rapid antigen and real‐time polymerase chain reaction tests were negative after 2 weeks. She was discharged home on antiretroviral therapy and TB therapy. Coinfection with both TB, HIV, and SARS‐CoV‐2 may be common in Cameroon but not reported. The similar clinical features of COVID‐19 and TB usually lead to misdiagnosis. Early diagnosis and initiation of appropriate treatment improve outcome.

Published: July 2022

AbstractElaborately designed π‐stacked molecular aggregates are significant for modulation of photophysical properties of polycyclic aromatic hydrocarbons (PAHs). Herein, a double hydrogen‐bonds trussed di(pyridyl)pyrrole‐perylene bisimide (HDPP‐PBI) was designed and its dimerization behavior was studied. HDPP‐PBI tends to form a quadruple PBI stack with a dimerization constant of ∼5.56×106 M−1. The dimerization was ascribed to synergistic intramolecular double hydrogen‐bonds formation and intermolecular π‐π stacking. Addition of CF3COOH, a hydrogen bond blocker, promotes the dimer to monomer transition. Accordingly, two distinct fluorescent films were prepared by drop‐casting of the dimerized or the monomeric HDPP‐PBI onto a substrate surface. Interestingly, the less‐emissive PBI quadruple stack‐based film showed a turn on response to acetone vapor, while the highly emissive HDPP‐PBI‐based film exhibited fluorescence quenching upon exposure to triethylamine vapor. We believe that the discovered synergistic effect in the PBI aggregates would enlighten the design of new PAHs aggregates with defined structures.

AbstractZinc–selenium (Zn–Se) batteries have generated great research interest because they could potentially meet the requirements of a high‐capacity, high energy density storage device. Unfortunately, efforts to control the shuttle effect of polyselenides have yielded limited success. Nanostructured carbon hosts with nonpolar surfaces have insufficient ability to restrict polyselenides within the cathode. Herein, first‐principles calculations are used to successfully study the merits of heteroatom‐doped graphene as an efficient sorbent with an excellent ability to inhibit the shuttle effect of polyselenides. The calculation results show that using B as a dopant could distinctly enhance interaction between hosts and polyselenides, which occur significant charge transfer with polyselenides and reduce the diffusion energy barrier of Zn ions. Then, we synthesized carbon/Se and boron‐doped carbon material/Se composite cathodes proving that B‐doped carbon could restrict the shuttle effect of polyselenides, which increases the electrochemical performance of Zn–Se batteries. Therefore, the theoretical study identifies a delightful restricted material that could potentially restrict the shuttle effect in Zn–Se batteries and provides a foundation and strategy for the fabrication of long‐life, high‐power‐density Zn–Se batteries.

Published: July 2022

AbstractThe development of sustainable energy technology has received considerable attention to meet the increasing energy demands and realize carbon neutrality. Hydrogen is a promising alternative energy source to replace fossil fuels and mitigate environmental issues. However, most hydrogen is produced by reforming fossil fuels, called gray hydrogen, and the production of gray hydrogen emits a large amount of carbon dioxide. As a sustainable approach, water electrolysis technology has been developed to produce high‐purity hydrogen, called green hydrogen. Among various technologies, water electrolysis equipped with an anion exchange membrane has been regarded as an attractive pathway for large‐scale H2 production at a low cost. The status of anion exchange membrane water electrolyzers is approaching toward megawatt‐scale H2 production by companies, which has the potential to become competitive technology for existing water electrolyzers (alkaline electrolyzer, proton exchange membrane electrolyser). This review article represents recent advances in the development of major components (membrane, catalyst, membrane electrode assembly) of anion exchange water electrolyzers. By recognizing the current water electrolysis performance and solving the remaining challenges, anion exchange membrane electrolysis can be a leading technology for green hydrogen production.

Published: July 2022

AbstractThe conversion of thermal energy into electricity can be successfully applied by novel renewable energy known as thermoelectricity (TE). Such thermoelectric generators (TEGs) are currently at a technological readiness level (TRL) of 3–5 (out of a level of 10) approaching laboratory prototypes. One of the major setbacks to achieve higher TRLs is the fact that the focus of research is concentrated on improving the electronic/transport properties (mainly affecting the figure of merit – ZT) of the materials, while the research on the mechanical properties and the material‘s ability to adhere service conditions was left behind. Information about the mechanical properties of TE materials – elastic constants (e. g. Young's modulus and Poisson's ratio), strength, and fracture toughness – are paramount necessities (but not the only ones) for approaching practical TEGs. The elastic constants provide an understanding of the material‘s stiffness, while the strength and fracture toughness provide the loading conditions the material can endure. This work summarizes the various mechanical properties and measuring methods along with all up‐to‐date published data of these properties for inorganic TE materials. This work aims to expose the TE community to the under‐looked and nearly untreated field of research. Also, for the first time, a statistical analysis of the collected data was employed to highlight cross relations between mechanical, and physical properties and those who had a high Pearson's correlation parameter are presented. These correlations in turn have the potential to expedite the development and screening of inorganic TE materials for the various applications needed.

Published: July 2022

SummaryIn recent years, the WSN are emerging swiftly since it finds applications in various domains including weather monitoring, attack detection, industrial monitoring, monitoring of submarine organisms, patient monitoring as well as the monitoring of ecological disorders. But WSN is also influenced by various other factors like network lifetime and energy consumption. It is necessary to provide an energy effective protocol to conquer certain troubles that includes packet delivery ratio, network lifetime, residual energy as well as effective routing in WSN. Therefore, this article aims to propose a novel protocol to enhance the energy efficiency of the network thereby providing an optimal routing path. This can be achieved by selecting an optimal cluster head that maintains communication between the base station and the sensor node. In this article, a novel multi‐objective moth swarm based sailfish (MOMS‐SF) technique is employed in selecting an optimal cluster head. The proposed MOMS‐SF technique enhances the network lifetime and minimizes the energy consumption of the network. Finally, the evaluation results are conducted to determine the network performances of the proposed MOMS‐SF approach. Also, a comparative analysis is carried out and the graphical analyzes for various parameters are made for various approaches to determine the effectiveness of the proposed system.
Modified unbiased estimators for population variance: An application for COVID‐19 deaths in Russia
Authors: Oncel Cekim Hatice 
Published: July 2022

SummaryThe article deal with the class unbiased forms of the variance estimators using Hartley–Ross type in the simple random sampling. The mean squared error (since it is an unbiased estimator, variance is calculated) of the suggested, up to the first order of approximation, is derived. The proposed estimator using COVID‐19 data in Russia has been proven to be more efficient than the considered estimators under the conditions. Thus, it allows us to see the variance estimator that best predicts the change according to federal regions in Russia's number of COVID‐19 deaths. This study also provides an unbiased family of estimators that are more efficient than existing estimators, which estimate the variance of the total death number of COVID‐19 based on the daily new cases number. The most important difference of this article from other studies in the literature is that it is the first study to examine the variance of the COVID‐19 cumulative mortality value in terms of variance estimation using the simple random sampling method with the auxiliary variable.

AbstractThe forced oscillation technique (FOT) is a powerful and accurate method to quantify the mechanical properties of the airways and tissues of the respiratory system. Here we provide a detailed protocol for the measurement of mouse respiratory mechanical parameters. We present a procedure for mouse endotracheal intubation using a handcrafted intubation platform and confirmation module. The FlexiVentFX™ system (Scireq Inc.) is utilized for the thorough assessment of lung function with the FlexiWare™ software serving as a unit for the planning, experimentation, and analysis. The protocol has been standardized and adapted for use by our center for lung‐function phenotyping of mouse models generated for the International Mouse Phenotyping Consortium (IMPC). The simplified steps, technical considerations, and integrated hardware‐software demonstration make this protocol adaptable and implementable for researchers interested in using FOT for lung‐function evaluation. © 2022 The Authors.

Published: July 2022

AbstractA hydrazine‐mediated approach towards renewable aromatics production via Diels‐Alder aromatization of readily available, biobased furfurals was explored as alterative to the more classical approaches that rely on reactive but uneconomical reduced dienes (e. g., 2,5‐dimethylfuran). To enable cycloaddition chemistry with these otherwise unreactive formyl furans, substrate activation by N,N‐dimethyl hydrazone formation was investigated. The choice of the reaction partner was key to the success of the transformation, and in this respect acrylic acid showed the most promising results in the synthesis of aromatics. This strategy allowed for selectivities up to 60 % for a complex transformation consisting of Diels‐Alder cycloaddition, oxabridge opening, decarboxylation, and dehydration. Exploration of the furfural scope yielded generic structure‐reactivity‐stability relationships. The proposed methodology enabled the redox‐efficient, operationally simple, and mild synthesis of renewable (p‐disubstituted) aromatics of commercial importance under remarkably mild conditions.

Published: July 2022

AbstractObjectiveThe objective of this study is to examine the association between indicators of social adversity, including socioeconomic status and race/ethnicity, and children's disordered eating behaviors and attitudes.MethodsChildren ages 8–10 years old (n = 183) were recruited from Michigan. Data were collected through in‐home surveys. The Children's Eating Attitudes Test (ChEAT‐24) measured disordered eating attitudes and behaviors in the sample. Cumulative social adversity was considered the sum of four binary variables: caregiver race/ethnicity, caregiver education, household income, and child‐reported food security status. Linear mixed models examined the association between social adversity indicators and ChEAT‐24 scores.ResultsChildren of primary caregivers of color had significantly higher ChEAT‐24 scores than children of white caregivers (p = .03). Children who reported food insecurity had significantly higher ChEAT‐24 scores compared to children who reported food security (p = .01). Compared to children with the lowest social adversity score, children with the highest score had a 4.8‐unit higher ChEAT‐24 score (95% CI .3–9.4), after adjusting for covariates. A significant trend was observed for greater social adversity and higher ChEAT‐24 score (p‐trend = .02).ConclusionA linear association was observed between greater social adversity and more disordered eating behaviors and attitudes among children in this sample. These findings emphasize the need for eating disorder research in children from racial/ethnic minorities and socioeconomically disadvantaged populations to support future prevention efforts.Public SignificanceGreater exposure to social adversity was associated with more disordered eating behaviors among preadolescent children. Given that eating disorders are understudied in lower‐income and minority racial/ethnic populations, this study highlights the need for additional research to better support prevention and treatment efforts among children from socioeconomically diverse backgrounds.
A practical application of methodologies to determine asset criticality and work order prioritization
Authors: English Lar , Yunusa‐Kaltungo Akilu 
Published: July 2022

AbstractThe ability of a company to prioritize work orders is an essential part of managing work which in turn is vital when it comes to delivering maintenance services. The authors have drafted a tutorial paper that outlines a real‐world application of practices which determine asset criticality and work order prioritization. The paper initially provides a background on the estate of the featured facilities department. An approach is then provided to determine asset criticality across an asset register which factors in the importance of each site in relation to the overall mission of the estate. The final step is to use asset criticality, work urgency and a time factor to address work order prioritization. If a company wishes to adopt the approach in this paper but does not possess a Computerized Maintenance Management System (CMMS) with the required functionality, they could instead utilize a spreadsheet‐based approach incorporating data exports from their resident CMMS. While this paper features data from the facilities management industry, the approach is agnostic and can be implemented by maintenance departments regardless of the industry.
