Authors: Yahaya Rusya Iryanti , Md Arifin Norihan , Pop Ioan , Md Ali Fadzilah , Mohamed Isa Siti Suzilliana Putri 
Published: August 2022

PurposeThis paper aims to study the stagnation point flow of Al2O3–Cu/H2O hybrid nanofluid over a radially shrinking disk with the imposition of the magnetic field, viscous-Ohmic dissipation and convective boundary condition.Design/methodology/approachSimilarity variables are introduced and used in reducing the governing partial differential equations into a system of ordinary differential equations. A built-in bvp4c solver in MATLAB is then used in the computation of the numerical solutions for equations (7) and (8) subject to the boundary conditions (9). Then, the behavior of the flow and thermal fields of the hybrid nanofluid, with various values of controlling parameters, are analyzed.FindingsThe steady flow problem resulted in multiple (dual) solutions. A stability analysis performed to identify the stable solution applicable in practice revealed that the first solution is stable while the second solution is unstable. The skin friction coefficient and Nusselt number of the hybrid nanofluid are found to be greater than the Al2O3–H2O nanofluid. Thus, the hybrid nanofluid has a better heat transfer performance than the nanofluid. Besides that, the presence of the magnetic field, suction, convective boundary condition and the enhancement of nanoparticle volume fraction of Cu augments the skin friction coefficient and Nusselt number of the hybrid nanofluid. Meanwhile, the presence of viscous-Ohmic dissipation reduces the heat transfer performance of the fluid.Originality/valueTo the best of the authors’ knowledge, the present results are original and new for the study of the flow and heat transfer of Al2O3–Cu/H2O hybrid nanofluid past a permeable radially shrinking disk. Considerable efforts have been directed toward the study of the boundary layer flow and heat transfer over stretching/shrinking surfaces and disks because of its numerous industrial applications, such as electronic, power, manufacturing, aerospace and transportation industries. Common heat transfer fluids such as water, alumina, cuprum and engine oil have limited heat transfer capabilities due to their low heat transfer properties. In contrast, metals have higher thermal conductivities than these fluids. Therefore, it is desirable to combine the two substances to produce a heat transfer medium that behaves like a fluid but has higher heat transfer properties.
Study on the influence of carbon trading pilot policy on energy efficiency in power industry
Authors: Hu Shiqian , Li Dan , Wang Xiaodan 
Published: August 2022

Purpose
To cope with climate change and achieve the dual carbon goal, China has actively promoted the implementation of carbon trading pilot policy, among which the power industry plays an important role in China’s carbon emission reduction work. The purpose of this paper is to study the influence of carbon trading policy on the energy efficiency of power industry and achieve the comprehensive goal of carbon emission reduction, carbon peak and carbon neutralization.

Design/methodology/approach
This paper constructs the difference-in-differences model based on 2012–2019 provincial data to study the impact of carbon trading policy on energy efficiency in the power industry and its effect path. Heterogeneity analysis was conducted to compare the effects of carbon trading policy in eastern, central and western regions as well as at different levels of power structures.

Findings
Carbon trading policy can significantly improve the energy efficiency of the power industry, and the policy effect is more significant in eastern and western regions and areas with high power structure. Mechanism analysis shows that carbon trading policy mainly influences the energy efficiency of power industry by environmental protection investment, power consumption demand and industrial structure.

Originality/value
This paper uses provincial panel data to deeply study the influence of carbon trading policy on energy efficiency of the power industry and its effect path. By constructing the difference-in-differences model, this paper empirically analyzes the governance effect of carbon trading policy. Meanwhile, it controls individual and time effects to solve the endogeneity problem prevalent in previous literature.
COVID lessons: was there any way to reduce the negative effect of COVID-19 on the United States economy?
Authors: Mahmoudi Mohammadreza 
Published: August 2022

PurposeThis paper aims to assess the economic impact of uniform COVID-controlling policies that were implemented by the US government in 2020 and compare it with hypothetical targeted policies that consider the heterogenous effect of COVID-19 on different age groups.Design/methodology/approachThe author began by showing that the adjusted SEQIHR model is a good fit to the US COVID-induced daily death data in that it can capture the nonlinearities of the data very well. Then, he used this model with extra parameters to evaluate the economic effects of COVID-19 through its impact on the job market.FindingsThe results show that targeted COVID-controlling policies could reduce the US death rate and GDP loss to 0.03% and 2%, respectively. By comparing these results with uniform COVID-controlling policies, which led to a 0.1% death rate and 3.5% GDP loss, we could conclude that the death rate reduction is 0.07%. Approximately 378,000 Americans died because of COVID-19 during 2020, therefore, reducing the death rate to 0.03% means saving a significant proportion of the COVID-19 casualties, around 280,000 lives.Originality/valueTo the best of the author's knowledge, this paper is the first study to assess the economic impacts of COVID-controlling policies by using the multirisk SEQIHR model.

Purpose
Islamic Insurance (Takaful) played a dynamic role in Islamic Social Finance (ISF). The popularity of the Takaful concept is being increased with each passing day. To describe the process, it is important to understand past areas of research, research differences, areas of unknown Takaful research, as well as the existing data. However, the purpose of the paper is to provide a comprehensive analysis of the development of qualitative research by carefully examining the nature of science and aspects of social relations in ISF.

Design/methodology/approach
Field, concerns with analysing and measuring the scholarly literature, quantitative characteristics of sciences and scientific technologies are known as scient metrics. This research includes queries such as “Islamic Insurance”, “Takaful” and “Shariah Insurance” as a reference in “Article title, Abstract and Keywords” based on Scopus from 2002 to 2022. This analysis was conducted in February 2022. The Bibliometrics, R-Studio, VOSviewer and Excel software are used to analyse the collected data and apply the bibliometric analysis.

Findings
The gist of the results and findings is that there are clear research gaps in the existing literature on Takaful. The available research on this subject does cover historical background, concept and models of Takaful and customer satisfaction towards Takaful model. Very important areas such as use of technology for bringing innovation in Takaful products and Shariah issues in existing practice and their solutions were not found in the present literature on Takaful.

Published: August 2022

PurposeWhile technical vocational education training (TVET) has been studied in-depth, the evolution and performance patterns of the subject remain unknown and limited. A bibliometric analysis was performed to examine the global scientific literature to assess the state of the art in TVET research over the past 23 years.Design/methodology/approachThe Web of Science (WoS) database was searched to explore TVET-related research from 1999 to 2021, resulting in the identification of 7,512 articles. The VOSviewer software was used to investigate the network of collaboration between authors, institutions, countries and author keywords.FindingsThe results reveal that the subject categories of “education” and “educational research” are the most prolific contributors to TVET-related research, with 3,314 articles. Most of the previous studies in Phase I (1999–2006) focussed on human capital resources development in the TVET sector. Phase II (2007–2014) follows with the centralisation of TVET, focussing on technology transition in education. However, in Phase III (2015–2021), researchers appear to focus on vocational studies in higher education towards increasing the productivity of human resources via the implementation of technology transition.Originality/valueThe valuable findings of this study can facilitate better understanding among scholars on the trends of TVET research developments and on the direction of future research.
Spatial planning for restoration in Cerrado: Balancing the trade‐offs between conservation and agriculture
Authors: Schüler Jéssica , Bustamante Mercedes M. C. 
Published: August 2022

Abstract

The Brazilian Cerrado, the most biodiverse savanna globally with great importance for water and carbon conservation, faces the impacts of rapid and extensive land conversion, mainly for agricultural uses. The native Cerrado vegetation originally covered an area of 204 Mha however, 43% has been converted to human use. Pastures are the major land use category in Cerrado, covering 57 Mha, 28% of its area. Most of these pastures are underused and present some degree of degradation, representing an opportunity for restoration programs and agriculture expansion without further conversion of natural areas. The restoration of the Cerrado's degraded pastures is a source of recovery of ecosystem services, however, it might involve synergies and trade‐offs between ecosystem services and stakeholders.

To evaluate potential trade‐offs, we modelled seven scenarios for prioritization for restoration, focusing on pasture areas on a biome scale. We considered biodiversity, water‐related ecosystem services, potential carbon stock and agriculture aptitude to understand the trade‐offs between each feature and the conflicts with agriculture. We also applied the same prioritization logic for one Cerrado ecoregion to understand the importance of planning on a finer scale.

We identified important trade‐offs between the scenarios, especially with agriculture. The agriculture conflict scenario showed that 16 Mha of areas suitable to agriculture have also a high importance for restoration, representing a gain around 70% in ecosystem services and biodiversity. By refining the spatial scale of the prioritization process, we could also identify local conflicts and demands, which indicates the relevance of a local approach, allowing a more representative cover of the Cerrado's heterogeneity to minimize trade‐offs between different demands associated with restoration.

Policy implications. The restoration of degraded lands is an international priority to mitigate climate change as well as protect the biodiversity. Our work provides a better understanding of the trade‐offs and conflicts involved in the restoration of the Cerrado, a megadiverse savanna with great importance in agriculture. This understanding is key to implementing public policies that enable large‐scale restoration projects while optimizing biodiversity conservation, ecosystem services provision and minimizing conflicts with agriculture.
‘Omics‐guided prediction of the pathway for metabolism of isoprene by Variovorax sp. WS11
Authors: Dawson Robin A. , Rix Gregory D. , Crombie Andrew T. , Murrell J. Colin 
Published: August 2022

AbstractBacteria that inhabit soils and the leaves of trees partially mitigate the release of the abundant volatile organic compound, isoprene (2‐methyl‐1,3‐butadiene). While the initial steps of isoprene metabolism were identified in Rhodococcus sp. AD45 two decades ago, the isoprene metabolic pathway still remains largely undefined. Limited understanding of the functions of isoG, isoJ and aldH and uncertainty in the route of isoprene‐derived carbon into central metabolism have hindered our understanding of isoprene metabolism. These previously uncharacterised iso genes are essential in Variovorax sp. WS11, determined by targeted mutagenesis. Using combined ‘omics‐based approaches, we propose the complete isoprene metabolic pathway. Isoprene is converted to propionyl‐CoA, which is assimilated by the chromosomally encoded methylmalonyl‐CoA pathway, requiring biotin and vitamin B12, with the plasmid‐encoded methylcitrate pathway potentially providing robustness against limitations in these vitamins. Key components of this pathway were induced by both isoprene and its initial oxidation product, epoxyisoprene, the principal inducer of isoprene metabolism in both Variovorax sp. WS11 and Rhodococcus sp. AD45. Analysis of the genomes of distinct isoprene‐degrading bacteria indicated that all of the genetic components of the methylcitrate and methylmalonyl‐CoA pathways are not always present in isoprene degraders, although incorporation of isoprene‐derived carbon via propionyl‐CoA and acetyl‐CoA is universally indicated.

Published: August 2022

AbstractBioconversion of waste animal fat (WAF) to polyhydroxyalkanoates (PHAs) is an approach to lower the production costs of these plastic alternatives. However, the solid nature of WAF requires a tailor‐made process development. In this study, a double‐jacket feeding system was built to thermally liquefy the WAF to employ a continuous feeding strategy. During laboratory‐scale cultivations with Ralstonia eutropha Re2058/pCB113, 70% more PHA (45 gPHA L−1) and a 75% higher space–time yield (0.63 gPHA L−1 h−1) were achieved compared to previously reported fermentations with solid WAF. During the development process, growth and PHA formation were monitored in real‐time by in‐line photon density wave spectroscopy. The process robustness was further evaluated during scale‐down fermentations employing an oscillating aeration, which did not alter the PHA yield although cells encountered periods of oxygen limitation. Flow cytometry with propidium iodide staining showed that more than two‐thirds of the cells were viable at the end of the cultivation and viability was even little higher in the scale‐down cultivations. Application of this feeding system at 150‐L pilot‐scale cultivation yielded in 31.5 gPHA L−1, which is a promising result for the further scale‐up to industrial scale.

Authors: Carr Bethany L. , Jahangirifar Maryam , Nicholson Ann E. , Li Wentao , Mol Ben W. , Licqurish Sharon 
Published: August 2022

BackgroundPostpartum haemorrhage (PPH) remains a leading cause of maternal mortality and morbidity worldwide, and the rate is increasing. Using a reliable predictive model could identify those at risk, support management and treatment, and improve maternal outcomes.AimsTo systematically identify and appraise existing prognostic models for PPH and ascertain suitability for clinical use.Materials and MethodsMEDLINE, CINAHL, Embase, and the Cochrane Library were searched using combinations of terms and synonyms, including ‘postpartum haemorrhage’, ‘prognostic model’, and ‘risk factors’. Observational or experimental studies describing a prognostic model for risk of PPH, published in English, were included. The Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies checklist informed data extraction and the Prediction Model Risk of Bias Assessment Tool guided analysis.ResultsSixteen studies met the inclusion criteria after screening 1612 records. All studies were hospital settings from eight different countries. Models were developed for women who experienced vaginal birth (n = 7), caesarean birth (n = 2), any type of birth (n = 2), hypertensive disorders (n = 1) and those with placental abnormalities (n = 4). All studies were at high risk of bias due to use of inappropriate analysis methods or omission of important statistical considerations or suboptimal validation.ConclusionsNo existing prognostic models for PPH are ready for clinical application. Future research is needed to externally validate existing models and potentially develop a new model that is reliable and applicable to clinical practice.

Published: August 2022

AbstractObjectiveWe propose a new scoring system (I‐PET) combining whole body scan (WBS) and FDG findings to identify patients who have or are likely to become refractory to radioactive iodine.DesignRetrospective analysis of 142 patients age >18 with differentiated thyroid cancer who had a F‐18 labelled fluoro‐2‐deoxyglucose (18F‐FDG) positron emission tomography (PET) and WBS within a 6‐month period between 2010 and 2020. Pairs of 18F‐FDG PET and WBS were reviewed by three independent nuclear medicine physicians and an I‐PET score was assigned: I‐PET [0]: Iodine −ve/FDG −ve, I‐PET [1]: Iodine +ve/FDG −ve, I‐PET [2]: Iodine +ve/FDG +ve and I‐PET [3]: Iodine −ve/FDG +ve. Patients with FDG +ve lesions (I‐PET [2] and I‐PET [3]) were further classified into groups A and B if SUVmax was ≤5 or >5, respectively. Follow‐up data were obtained by chart review. Progression was defined as structural progression as per RECIST 1.1 or further surgical intervention; or biochemical progression as unstimulated thyroglobulin increasing >20% from baseline.ResultsOf 142 patients included in the study 121 patients had follow‐up data available for review. At baseline, 49 patients were classified as I‐PET [0], 10 as I‐PET [1], 16 as I‐PET [2] and 46 as I‐PET [3]. Progression was seen in 11/49 (22%) of I‐PET [0], 4/10 (40%) of I‐PET [1], 10/16 (63%) of I‐PET [2] and 34/46 (74%) of I‐PET [3] (p < 0.001). I‐PET [2B] and I‐PET [3B] had a progression rate of 88% (7/8) and 78% (25/32), respectively. I‐PET [3B] were 9.6 times more likely to commence multikinase inhibitor therapy (p = 0.001) and had 8 times greater mortality (p = 0.003) than patients in other I‐PET groups combined.ConclusionI‐PET is a simple readily acquired imaging biomarker that potentially enhances the dynamic risk stratification and guide treatment in thyroid cancer.
Thinking and doing with childism in children's literature studies
Authors: Deszcz‐Tryhubczak Justyna , García‐González Macarena 
Published: August 2022

AbstractIn this article we share our reflections on how childism has enabled us to navigate theoretical assumptions shaping our field and develop new positions and research practices fostering child–adult interdependencies. Justyna Deszcz‐Tryhubczak has relied on childism as a framework for the introduction of participatory research with young readers as a way for advancing child–adult collaboration. Macarena García‐González has deployed childism to think about adultism and its analogies to sexism. Although we offer a critique of childism as an essentializing concept, we also show how for both of us it has served as a gateway towards other approaches, and especially post‐anthropocentric understandings both of texts, readers and the world and of our critical engagements. Finally, we argue that childism may remain a productive starting point for further openings in children's literature and culture studies and childhood studies if it becomes a plural and messy notion that questions the discourse of hope for a better future as defining children's lives.

Published: August 2022

AbstractBackgroundProgrammed cell death protein (PD‐1) and programmed death‐ligand 1 (PD‐L1) inhibition checkpoint blockade leads to various cutaneous adverse reactions, including bullous pemphigoid and lichen‐planus‐like reactions. However, lichen planus pemphigoides (LPP), manifesting histopathologic features of both lichen planus and bullous pemphigoid, has more rarely been associated with immunotherapy.MethodsThe clinical and histopathologic findings of three patients were examined, and a review of cases of LPP and bullous lichen planus secondary to PD‐1 inhibitor therapy was performed.ResultsThree patients (two with advanced non‐small‐cell lung adenocarcinoma and the third with metastatic breast cancer) presented with both lichenoid eruptions and bullae. Biopsy of the lesions revealed lichenoid tissue reactions in all three patients. Together with the histopathologic findings, direct immunofluorescence (DIF) showing linear C3 and IgG deposition and positive enzyme‐linked immunosorbent assay (ELISA) showing BP180 positivity supported a diagnosis of LPP in two patients. The third patient in our series also showed confirmatory ELISA testing supporting LPP.ConclusionsLichen planus pemphigoides is a distinct cutaneous toxicity to checkpoint inhibitor therapy illustrates a possible pathogenic mechanism and the importance of dermatopathology recognition to render an accurate diagnosis.
