Published: September 2022

AbstractThis work intends to delineate the petrophysical properties and the reservoir quality of the Albian sequence in the Mesopotamian Basin which has been deposited as a siliciclastic sequence. The well log data (including the caliper, gamma-ray, density, photoelectric factor 'PEF', neutron, sonic, and resistivity logs), derived from eight wells in the SWM (Southwest Mesopotamian) Oilfield, was studied and interpreted using the appropriate software (IP3.6). These borehole data indicate the necessity to divide the sequence into five reservoir rock units (U1, U2, M, L1, and L2 units). This enabled depicting the porosity, shale volume, water saturation, and net-pay thickness in the vertical and horizontal directions. It is indicated that the M and L1 units are the most promising units with good to very good porosity (∅ ≥ 17.2%), low water saturation (Sw ≤ 28.0%), and acceptable shale volume (Vsh ≤ 8.4%). The net-pay thickness varies between 32.8 and 77.4 m in the different wells of the SWM Oilfield. The well log data were supported by more detailed conventional core data including porosity (∅He) and permeability (k), from which the reservoir quality parameters were estimated precisely. In the present study, reservoir quality assessment based on conventional core data is considered for the first time for evaluating and discriminating the Albian–Aptian sequence in the Southwest Mesopotamian field into reservoir zones and hydraulic flow units. The estimated reservoir parameters include the Flow Zone Indicator (FZI), the Reservoir Quality Index (RQI), and the effective pore radius (R35). Based on the available core data and the estimated reservoir quality parameters, the studied sequence was divided into three reservoir rock types (RRT1–3). The best petrophysical properties have been assigned for the medium-grained sandstone of the RRT1 that dominates in the L1 and the M units (av. ∅He = 23.0%, av. k = 1581 mD, av. R35 = 23.7 μm, av. FZI = 7.368 μm, and av. RQI = 2.304 μm). On the other side, the fine-grained sandstone of the RRT3 is characterized by the lowest petrophysical properties and reservoir quality parameters (av. ∅He = 17.1%, av. k = 5.49 mD, av. R35 = 0.92 μm, av. FZI = 0.603 μm, and av. RQI = 0.136 μm). The integration between the well log and core data of the studied Albian sequence stated that the M and L1 units are the most promising reservoir units. They are predominated by medium-grained and fine to medium-grained sandstones of the RRT1 and the RRT2, respectively. This well log-core data integration is applicable to the different oilfields in the different fields in the Mesopotamian Basin and other basins in south Iraq and elsewhere.
Practical learning opportunities and changes in teachers’ self-efficacy beliefs: Does the development of bachelor student teachers’ competence differ before and during COVID-19?
Authors: König Johannes , Gerhard Kristina , Jäger-Biela Daniela J. 
Published: September 2022

AbstractThis article investigates changes in student teachers’ teacher self-efficacy beliefs (SEBs) as part of their competence development during their three-year bachelor’s program and how these changes can be explained through practical learning opportunities. Using two bachelor’s student teacher cohorts who studied during and prior to COVID-19, differences in the development of their competence are analyzed longitudinally over three time points. Unexpectedly, no increase in SEBs was observed; rather, a significant decline was identified, with little practical relevance for the cohort who had studied before and medium practical relevance for the cohort who studied during the pandemic. At the end of their bachelor’s program, students in the cohort who studied before the pandemic reported slightly higher levels of SEBs than those who had to study during the pandemic. A path model indicates that studying during the pandemic negatively impacted both practical learning opportunities and changes in student teachers’ SEBs, whereas practical learning opportunities positively impacted SEBs changes. The findings’ implications for practical learning opportunities in initial teacher education are discussed.

Abstract
Purpose
The elevated frequency of discordance for congenital hypothyroidism (CH) phenotype between monozygotic twins suggests the involvement of non-mendelian mechanisms. The aim of the study was to investigate the role of epigenetics in CH pathogenesis.

Methods
A genome-wide DNA methylation analysis was performed on the peripheral blood of 23 twin pairs (10 monozygotic and 13 dizygotic), 4 concordant and 19 discordant pairs for CH at birth.

Results
Differential methylation analysis did not show significant differences in methylation levels between CH cases and controls, but a different methylation status of several genes may explain the CH discordance of a monozygotic twin couple carrying a monoallelic nonsense mutation of DUOX2. In addition, the median number of hypo-methylated Stochastic Epigenetic Mutations (SEMs) resulted significantly increased in cases compared to controls. The prioritization analysis for CH performed on the genes epimutated exclusively in the cases identified SLC26A4, FOXI1, NKX2-5 and TSHB as the genes with the highest score. The analysis of significantly SEMs-enriched regions led to the identification of two genes (FAM50B and MEG8) that resulted epigenetically dysregulated in cases.

Conclusion
Epigenetic modifications may potentially account for CH pathogenesis and explain discordance among monozygotic twins.
Parallel temporal feature selection based on improved attention mechanism for dynamic gesture recognition
Authors: Chen Gongzheng , Dong Zhenghong , Wang Jue , Xia Lurui 
Published: September 2022

AbstractDynamic gesture recognition has become a new type of interaction to meet the needs of daily interaction. It is the most natural, easy to operate, and intuitive, so it has a wide range of applications. The accuracy of gesture recognition depends on the ability to accurately learn the short-term and long-term spatiotemporal features of gestures. Our work is different from improving the performance of a single type of network with convnets-based models and recurrent neural network-based models or serial stacking of two heterogeneous networks, we proposed a fusion architecture that can simultaneously learn short-term and long-term spatiotemporal features of gestures, which combined convnets-based models and recurrent neural network-based models in parallel. At each stage of feature learning, the short-term and long-term spatiotemporal features of gestures are captured simultaneously, and the contribution of two heterogeneous networks to the classification results in spatial and channel axes that can be learned automatically by using the attention mechanism. The sequence and pooling operation of the channel attention module and spatial attention module are compared through experiments. And the proportion of short-term and long-term features of gestures on channel and spatial axes in each stage of feature learning is quantitatively analyzed, and the final model is determined according to the experimental results. The module can be used for end-to-end learning and the proposed method was validated on the EgoGesture, SKIG, and IsoGD datasets and got very competitive performance.

AbstractThe World Health Organization (WHO) advocates investment in high-quality undergraduate education in geriatric medicine as a means of meeting the future needs of the aging population. However, there is a lack of evidence for the optimal delivery of training in this area. Rigorous pedagogical research is required to determine the most effective way to equip tomorrow’s doctors with the skills and knowledge to care for older adults with complex health and social care needs. The transition between two undergraduate medical curricula meant that Bristol Medical School (BMS) was uniquely positioned to innovate and evaluate undergraduate education in geriatric medicine. This transition marked BMS’ departure from a ‘traditional’ curriculum to case-based learning. The outgoing curriculum included a 4-week unit in geriatrics, whilst the new programme includes an 18-week clerkship titled ‘Complex Medicine in Older People’ (CMOP). CMOP is a clinical clerkship with 18 cases at its core, covering the fundamental aspects of geriatric medicine. The core cases and clinical learning are enhanced with five expert lectures, six tutorials and three journal clubs. Reflective practice is modelled and promoted with Balint groups and a book club. Consolidative workplace-based assessments and clinical portfolio mirror those used in postgraduate training, preparing students for professional practice. CMOP is iteratively improved in real-time using staff and student feedback. This marked shift in mode and duration of teaching affords the opportunity to evaluate the impact of differing education in geriatrics, providing an evidence-based model for teaching on aging.

Published: September 2022

Abstract
The purpose of this paper is to conduct a numerical simulation of the stroke patient's cerebral arteries and investigate the flow parameters due to the presence of stenosis. The computational fluid dynamics (CFD) simulations are based on simplified and realistic cerebral artery models. The seven simplified models (benchmarks) include straight cylindrical vessels with idealized stenosis with variable d/D (0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1). The realistic model of the cerebral artery is based on magnetic resonance imaging (MRI) for patient-specific cerebral arteries. The simulation for the realistic model of the cerebral artery is performed at boundary conditions measured by ultrasonography of the input and the output flow profiles (velocity and pressure). The obtained CFD results of the benchmarks are validated with actual data from the literature. Furthermore, a previous vascular contraction is assumed to be exist and the effect of this contraction area ratio on the blood flow regime is discussed and highlighted. Furthermore, CFD results show that a certain vascular contraction area critically affects the blood flow which shows increasing the wall shear stress WSS at the stenosis site. An increase in the blood velocity and vortex appears after the contraction zone, this lead to vessel occlusion and strokes.

Article highlights

The pressure drop across the arterial contraction is reduced when the area ratio d/D is increased.

In some cases, the vortex can prevent blood flow from crossing, this leads to vessel occlusion especially at low d/D

The WSS near the contraction area is high. Increasing the WSS can cause embolism that leads to lead to vessel occlusion.

Published: September 2022

AbstractThe rapid expansion of the fast fashion industry brings about environmental concerns such as dyestuffs-related water pollutions and waste textiles. Conventional wastewater-disposal strategies emphasize the optimization of photocatalytic activity to improve pollutant degradation efficiency, while the absorptivity, recyclability and sustainability of photocatalysts are always ignored. The overproduced textiles are still in urgent of being recycled and reutilized in eco-friendly approaches. In this work, a scalable dyeing technology is employed to achieve green and sustainable reutilization of waste textiles. The functionalized TiO2/reduced graphene oxide wool fabrics show excellent sustainability, remarkable adsorbing capacity and enhanced photocatalytic performance. By taking advantage of these properties, we develop an integrated strategy of night-time adsorption and day-time photodegradation which could significantly optimize the dyestuffs degradation efficiency. The concept of waste textiles reutilization and wastewater treatment in this work provides practical potential for efficient and sustainable environmental remediation.

In particular, the optimization is performed with respect to both to the control strategies and to the set of contact points ensuring a planar, frictionless, first-order force-closure of the target. The case of an elliptic target object is discussed in detail, and numerical simulation are presented.
Metacognitive strategies in solving mathematical word problems: a case of Rwandan primary school learners
Authors: Kusaka Satoshi , Ndihokubwayo Kizito 
Published: September 2022

AbstractThis study aims to understand the use of metacognitive skills by Rwandan learners while solving mathematical word problems. We interviewed and assessed third-, fourth- and fifth-grade learners from a public primary school. The following three points emerged. First, the metacognitive skills of learners with correct answers were considerably higher than that of those with incorrect answers. Second, although there was no considerable difference in metacognitive skills between learners who answered correctly and those who did not at the stage of ‘understand the problem’, considerable differences were observed in the ‘search for solving methods’ and ‘execute the solving methods’ and ‘examine the answer’ stages. During the ‘search for solving methods’ and ‘execute the solving methods’ stage, learners who answered correctly mainly used three metacognitive skills to control their learning—‘writing the process by sentences’, ‘drawing tables’ and ‘drawing pictograms’. Third, when metacognitive skills were measured and scored, the average scores for fifth and third graders were similar. The interview revealed that the teachers of third graders taught them metacognitive strategies in mathematics lessons. It can be inferred that consequently, the metacognitive skills of third graders were raised to be as high as those of fifth graders. Although this is only a single empirical study in Rwanda, it is a major step towards improving the standard of mathematics education in African countries. In the future, similar research must be conducted in other African countries to accumulate relevant research results.
Short- and long-run macroeconomic impacts of the 2010 Iranian energy subsidy reform
Authors: Zarepour Zahra 
Published: September 2022

AbstractThis paper examines the short- and long-run effects of the 2010 Iranian energy subsidy reform on macro indicators including GDP and inflation. The subsidy reform, which consists of a simultaneous energy subsidy cut and a cash transfer to households, is not fiscally motivated but instead aims to reduce energy consumption. Using timeseries to analyse the dynamics of the macro variables in response to the subsidy reform elements (energy price increase, and cash transfer), this study reveals that the subsidy reform has a negative effect on the economy in the short- and mid-term, and the cash transfer to households does not fully compensate for this adverse effect. These results are robust and consistent across specifications. The main channel that transmits the effect of energy price to GDP is value-added of industry and service sectors. The long-run analysis rejects the existence of a long-run relationship between the energy subsidy reform and GDP. The findings indicate that the energy subsidy reform does not result in a reduction in energy consumption. These findings challenge the environmental aspect of the fossil fuel subsidy reforms as stand-alone policies without major reforms in the energy efficiency of economic sectors.
Different but the Same? Comparing Drivers and Barriers for Circular Economy Innovation Systems in Wood- and Plastic-Based Industries
Authors: Holzer Daniel , Mair-Bauernfeind Claudia , Kriechbaum Michael , Rauter Romana , Stern Tobias 
Published: September 2022

AbstractCircular economy is an emerging concept that places an emphasis on strategies (e.g., reduce, reuse, recycle) to decouple resource use from economic growth, minimize waste and emissions, and maintain the highest utility along a product life cycle. The transition to a circular economy requires innovative solutions along entire value chains. This literature review was carried out to investigate the respective innovation systems that emerge along the wood-based and plastic-based value chains. To investigate different barriers to and drivers for the transition to a circular economy, the system functions of the technological innovation system framework were used. The results reveal that the two sectors hold different strategic positions and that barriers are dominant in the innovation system for plastics, while drivers are more prevalent in the innovation system for wood. This study is one of the first to direct a focus toward different industrial origins and their underlying logic, contributing to a better overall understanding of the circular economy.

Authors: Yao Ning , Yang Xue-Fan , Zhu Bing , Liao Chun-Yan , He Ya-Ming , Du Jiang , Liu Nan , Zhou Chun-Bei 
Published: September 2022

Abstract
Background
Mobile phones are widely used in clinical settings and could be colonized by potential pathogenic bacteria which may lead to hospital-acquired infections (HAIs) transmission. This study aimed to determine the prevalence of bacterial contamination of healthcare workers’ (HCWs) mobile phones, identify bacterial isolates, and assess the factors associated with mobile phone contamination.

Methods
Self-administered questionnaire was used to collect the information on the demographic characteristics and the use of mobile phones. A total of 111 HCWs’ hands and their mobile phones were swabbed, then bacterial culture, isolation, and identification were performed. Univariate and multivariable logistic regression were applied to identify factors associated with mobile phone bacterial contamination.

Results
Totally 106 (95.5%) of the 111 mobile phones investigated were contaminated with bacteria. Staphylococcus epidermidis (13/111), Acinetobacter baumannii (4/111) and Staphylococcus aureus (3/111) were the predominant bacterial isolates from HCWs’ mobile phones. Univariate analyses showed that age, gender, profession and the frequency of mobile phone utilization were significantly associated with the number of bacterial colonization. Frequency of phone utilization (OR 8.366; 95% CI 1.496–46.797) was found to be the most significant factors associated with the qualified rate of mobile phones bacterial load. In addition, phone cover using was associated with the increased risk of mobile phone bacterial contamination.

Conclusion
There was cross-contamination between hands and phones. It is necessary to develop guidelines for mobile phone cleaning. Special attention needs to be paid to the disinfection of mobile phone covers to reduce contamination and transmission of pathogens.

AbstractIntroductionGout is the most prevalent inflammatory crystal arthropathy worldwide and is a chronic disease requiring strict, lifelong adherence to drug therapy and healthy lifestyles. Gout has a heavy burden on the patient's sexual health, owing to the associated inflammatory status, long-term complications, and chronic pain; however, the effects of gout also extend to the partner's sexual health.AimsWe aimed to investigate how the presence of a partner could influence the complex interaction between risk factors for sexual dysfunctions in gout in order to define novel strategies to improve sexual health and disease management.MethodsClinical and experimental data on the role of the couple in chronic diseases, as well as on the association between gout and sexual health, were searched through Pubmed.Main outcome measuresEvidence from studies describing how the presence of a couple and leveraging sexual health can improve management and clinical outcomes for chronic diseases.ResultsTreatment adherence can improve the sexual health of gout patients and their partners; likewise, by leveraging sexual health, it would be possible to promote better health-seeking behaviors, ultimately improving gout management.Clinical implicationsPromoting awareness of the sexual health relevance of gout can potentially be a pivotal strategy to improve disease management and prevent the progression of sexual dysfunctions from subclinical to overt forms.Strengths and limitationsIdentifying a bidirectional association between sexual health and disease management paves the way for improved disease control and can potentially prevent the development of sexual dysfunctions in couples affected by gout. However, the relevance of the couple has not been adequately addressed in gout management, and most evidence comes from other chronic diseases.ConclusionImproving gout management results in better sexual health, and vice-versa promoting better sexual health can improve disease control for gout. The presence of a partner improves the behavioral well-being of gout patients, with beneficial effects on both sexual health and gout management.
