Published: December 2021

A mathematical model for studying the 3-D dynamical structure of lee wave across a meso-scale mountain corner has been proposed for a mean flow with realistic vertical variation of wind and temperature. The basic flow consists of both zonal wind component (U) and meridional component (V), which are assumed to be dependent of height. The Brunt-Vaisala frequency (N) is also assumed to be dependent of height. This model has been applied to the mountain corner, in the North East India, formed by broadly North-South oriented Assam Burma Hills (ABH) and broadly East-West oriented Khasi Jayantia hills (KJH). The model has been solved following the quasi-numerical approach. The perturbation vertical velocity is expressed as a double integral. Three cases have been studied and in all cases the relation between the possible transverse and divergent lee wave numbers (k, l) and also the updraft/downdraft regions associated with lee waves at different heights has been mapped and discussed.

Published: December 2021

Utilization of synchronous generators on micro-hydro Power plant (PLTMH) need direct monitoring with some parameters such as voltage and current. From the results of the monitoring, the information can be obtained whether the synchronous generator installation is appropriate and produce the expected output power.
In some studies, the results of current and voltage measurements are still done by manual use of multimeter, so that the data obtained can not be recorded continuously. The purpose of this research is to create a monitoring system on synchronous generators using arduino-based data logger. Monitoring system using data logger is equipped with timing system.
Based on the research that has been done can be concluded that the monitoring system on synchronous generators using arduino-based data logger can record current, voltage, and power in real time resulting from generator performance and then record or save the data into the form of CSV file (comma separated values) every 2 seconds into the micro SD and the data can be displayed through Microsoft Office software namely Microsoft Excel.

Published: December 2021

Aims: Senna obtusifolia (L.) is an important wild herbaceous species for subsaharan Africa population. It is used in human food and traditional medicine to treat several deseases. In Burkina Faso, despite its potentialities, this species is of a little interest in scientific research. The aim of this study is to provide a good knowledge of the genetic diversity of this species.
Study Design: The experimental design used was a randomized Fischer block type with three replications.
Place and Duration of the Study: The study was carried out at Gampéla during 2018 rainy season.
Methodology: Seventy (70) accessions of Senna obtusifolia were used for the evaluation of agromorphological variability. A total of twenty-seven (27) quantitative traits were studied.
Results: The study revealed the existence of a great variability within the studied collection. Among the twenty-one (21) traits used for the analysis of variance (ANOVA), seventeen (17) variables significantly discriminate the accessions. A high heterogeneity was observed for the number of leaflets of the three first leaves and the number of floral pieces. In addition, significant correlations were observed between several variables. Indeed, the number of primary branches was positively correlated with the number of fruits per plant (r = 0.483), the number of grains per plant (r = 0.352) and the leaves biomass (r = 0.279). However, the number of days at flowering (NJF) is negatively correlated with the number of primary branches (r = -0.281). The variability obtained was structured in three groups. The third group is composed of accessions with the best agronomic performance that could be used in future breeding program.
Conclusion: A high agromorphological diversity of Senna obtusifolia was observed and could be used in a breeding program.

Published: December 2021

Vascular anomalies are one of the challenging diseases to manage, presenting in different age groups and with varied clinical course, of which hemangiomas are common which are vasoproliferative neoplasms and can occur in any organ. Depending on the age at presentation they are classified as congenital and infantile hemangiomas. Not much attention has been paid regarding the imaging and treatment modalities of vascular malformations particularly hemangiomas due to scarcity of literature related to this condition. Majority of these vascular malformations are self-limiting, but in a few cases these lesions may grow with age which can be treated surgically or by sclerotherapy which has been the safe, less invasive, economical and easily available modality for treating hemangiomas. Bleomycin is the main sclerosing agent used which is a cytotoxic anti-tumor antibiotic which was later found to have anti-cancer properties. In our case, a 9 year old male child presented to our institution with a lump in the left side of abdomen since birth. Contrast enhanced CT abdomens was suggestive of a vascular malformation. Patient was treated with sclerotherapy with intralesional bleomycin for which good results were noted by decrease in the size and vascularity of the swelling.

Published: December 2021

Abstract
Persistent symptoms, physical signs, and abnormal test results after acute coronavirus disease 2019 (COVID-19) illness have emerged as a significant problem in the current and ongoing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus pandemic. Finding a rational balance between compelling subjective symptoms and limited objective findings in patients with post-COVID-19 conditions is challenging. We advise caution in adopting attributions, explanations, and management strategies, and especially in conferring formal disability status, for these disorders until we understand them more completely. The prevalent uncertainties threaten both overevaluation and overtreatment, with substantial personal and societal consequences, and all stakeholders need to be both intellectually open and cautious going forward. This article highlights several concerns in evaluating and treating patients with enduring COVID-19-related illness.

Published: December 2021

AbstractWith an exponential rise in antimicrobial resistance and stagnant antibiotic development pipeline, there is, more than ever, a crucial need to optimize current infection therapy approaches. One of the most important stages in this process requires rapid and effective identification of pathogenic bacteria responsible for diseases. Current gold standard techniques of bacterial detection include culture methods, polymerase chain reactions, and immunoassays. However, their use is fraught with downsides with high turnaround time and low accuracy being the most prominent. This imposes great limitations on their eventual application as point‐of‐care devices. Over time, innovative detection techniques have been proposed and developed to curb these drawbacks. In this review, a systematic summary of a range of biosensing platforms is provided with a strong focus on technologies conferring high detection sensitivity and specificity. A thorough analysis is performed and the benefits and drawbacks of each type of biosensor are highlighted, the factors influencing their potential as point‐of‐care devices are discussed, and the authors' insights for their translation from proof‐of‐concept systems into commercial medical devices are provided.

Published: December 2021

AbstractAggregation‐structure formation of conjugated polymers is a fundamental problem in the field of organic electronics and remains poorly understood. Herein, the molar mass dependence of the aggregation structure of a high‐mobility conjugated copolymer (TDPP‐Se) comprising thiophene‐flanked diketopyrrolopyrrole and selenophene is thoroughly shown. Five batches of TDPP‐Se are prepared with the number‐average molecular weights (Mn) varied greatly from 21 to 135 kg mol−1. Small‐angle neutron scattering and transmission electron microscopy are combined to probe the solution structure of these polymers, consistently using a deuterated solvent. All the polymers adopt 1D rod‐like aggregation structures and the radius of the 1D rods is not sensitive to the Mn, while the length increases monotonically with Mn. By utilizing the ordered packing of the aggregated structure in solution, a highly aligned and ordered film is prepared and, thereafter, a reliable hole mobility of 13.8 cm2 V−1 s−1 is realized in organic thin‐film transistors with the moderate Mn batch via bar coating. The hole mobility is among the highest values reported for diketopyrrolopyrrole‐based polymers. This work paves the way to visualize the real aggregated structure of polymer semiconductors in solution and sheds light on the microstructure control of high‐performance electronic devices.

Published: December 2021

AbstractPowered by inexhaustible solar energy, photoelectrochemical (PEC) hydrogen/ammonia production and reduction of carbon dioxide to high added‐value chemicals in eco‐friendly and mild conditions provide a highly attractive solution to carbon neutrality. Recently, substantial advances have been achieved in PEC systems by improving light absorption and charge separation/transfer in PEC devices. However, less attention is given to the atomic design of photoelectrocatalysts to facilitate the final catalytic reactions occurring at photoelectrode surface, which largely limits the overall photo‐to‐energy conversion of PEC system. Fundamental catalytic mechanisms and recent progress in atomic design of PEC materials are comprehensively reviewed by engineering of defect, dopant, facet, strain, and single atom to enhance the activity and selectivity. Finally, the emerging challenges and research directions in design of PEC systems for future photo‐to‐energy conversions are proposed.
Consumer welfare consequences of the California drought conservation mandate
Authors: Buck Steven , Nemati Mehdi , Sunding David 
Published: December 2021

AbstractWe measure consumer welfare losses from reductions in water use following California's conservation mandate in 2015, which imposed utility service area‐specific conservation targets of 4% up to 36%. We document imperfect compliance with the mandate and discuss factors that may explain the pattern of reductions ultimately observed. The basis for calculating welfare losses is an econometric model of residential water demand that yields local demands with elasticities ranging from −0.56 to −0.10. In terms of economic efficiency, we estimate a 20% gain in consumer welfare under the efficient allocation of conservation reductions relative to the observed pattern of reductions.
Inclusion, belonging and intercultural spaces: A narrative policy analysis of playgroups in Australia
Authors: Townley Cris 
Published: December 2021

AbstractThis article employs narrative policy analysis to examine how community playgroups are constructed in the ECEC policy framework, in order to understand what might exclude families, and how more families can be included in community playgroups. Playgroups are a widespread and important component of early childhood education and care (ECEC) provision in Australia, where parents and carers meet weekly with their babies, toddlers and preschool children. They are sites of social support for parents, together with play‐based learning and socialisation activities for the children. Through the lens of intersectionality theory, four narratives are constructed through analysis of interviews with policy elite informants. The classic narrative draws on the enduring model of community playgroups from the 1970s, and the vulnerability narrative centres the supported playgroup model. The belonging narrative and the intercultural narrative indicate possibilities for future policy approaches to community playgroups.

Authors: Sacramento Jireh Joy D. , Albert Therese , Siegler Maxime , Moënne‐Loccoz Pierre , Goldberg David P. 
Published: December 2021

AbstractA new structurally characterized ferrous corrole [FeII(ttppc)]− (1) binds one equivalent of dioxygen to form [FeIII(O2−.)(ttppc)]− (2). This complex exhibits a 16/18O2‐isotope sensitive ν(O‐O) stretch at 1128 cm−1 concomitantly with a single ν(Fe‐O2) at 555 cm−1, indicating it is an η1‐superoxo (“end‐on”) iron(III) complex. Complex 2 is the first well characterized Fe‐O2 corrole, and mediates the following biologically relevant oxidation reactions: dioxygenation of an indole derivative, and H‐atom abstraction from an activated O−H bond.
Reversible Photoswitching between Fluorescence and Room Temperature Phosphorescence by Manipulating Excited State Dynamics in Molecular Aggregates

Published: December 2021

AbstractRegulation of fluorescence–phosphorescence pathways in organic molecular aggregate remains a challenge due to the complicated singlet–triplet excited state dynamics process. Herein, we demonstrated a successful example (o‐BFT) to realize photoreversible fluorescence and room temperature phosphorescence (RTP) switching based on an effective strategy of integrating a phosphor (dibenzofuran) with a photoswitch (dithienylbenzothiophene). o‐BFT exhibited dual emission of fluorescence and RTP in both powder and doping polymer film. Notably, the long‐lived RTP of o‐BFT could be repeatedly erased and restored through reversible photocyclization and decyclization under alternate ultraviolet and visible photoirradiation. In‐depth theoretical and spectroscopic investigations revealed that the triplet inactivation was dominated by a photo‐controlled triplet‐to‐singlet Förster resonance energy transfer from light‐activated o‐BFT to photoisomer c‐BFT. Yet, the initial fluorescence could be preserved in this process to afford a photoreversible fluorescence‐RTP switching.
Preparation of an eco‐friendly carbon–silicon dual‐phase rubber filler with humic acid and silica sol

Published: December 2021

AbstractA new type of carbon–silicon dual‐phase filler (CSDPF) was prepared from highly active and widely available humic acid and low‐cost silica sol as raw materials, which were further used for styrene butadiene rubber (SBR) by ball milling and carbonization methods. The effects of the silica sol content and the bis(3‐triethoxysilylpropyl) tetrasulfide (TESPT) on the structure and surface properties of the CSDPF were investigated systematically. Silica sol combined with humic acid in the carbon–silicon dual‐phase complexes in the form of SiOC, while the TESPT and carbon–silicon dual‐phase complexes were combined in the form of SiOSi in the CSDPF. As the content of silica sol increased in the dual‐phase complexes, the amount and particle size of silica on the surface of CSDPF increased. A certain amount of silica in the fabricated filler facilitated its subsequent modification and applications. Compared with CB/SBR (SBR filled with carbon black 660), the mechanical properties, thermal stability, wear resistance, and wet skid resistance of SBR filled with the CSDPF were significantly improved. This work provides a new strategy for developing CSDPF.

Published: December 2021

AbstractAugmented reality (AR) has recently been utilized as an integrative teaching tool in medical curricula given its ability to view virtual objects while interacting with the physical environment. The evidence for AR in medical training, however, is limited. For this reason, the purpose of this mixed method study was to evaluate the implementation of overlaying donor‐specific diagnostic imaging (DSDI) onto corresponding body donors in a fourth‐year, dissection‐based, medical elective course entitled anatomy for surgeons (AFS). Students registered in AFS course were separated into groups, receiving either DSDI displayed on Microsoft HoloLens AR head‐mounted display (n = 12) or DSDI displayed on iPad (n = 15). To test for the change in spatial ability, students completed an anatomical mental rotation test (AMRT) prior to and following the AFS course. Students also participated in a focus group discussion and completed a survey at the end of AFS, analyzed through thematic triangulation and an unpaired, Mann Whitney U test respectively, both addressing dissection experience, DSDI relevancy to dissection, and use of AR in anatomical education. Although statistically significant differences were not found when comparing student group AMRT scores, survey and discussion data suggest that the HoloLens had improved the students' understanding of, and their spatial orientation of, anatomical relationships. Trunk dissection quality grades were significantly higher with students using the HoloLens. Although students mentioned difficulties with HoloLens software, with faculty assistance, training, and enhanced software development, there is potential for this AR tool to contribute to improved dissection quality and an immersive learning experience.

Published: December 2021

AbstractCoronal mass ejections (CMEs) are more energetic than any other class of solar phenomena. They arise from the rapid release of up to erg of magnetic energy mainly in the form of particle acceleration and bulk plasma motion. Their stellar counterparts, presumably involving much larger energies, are expected to play a fundamental role in shaping the environmental conditions around low‐mass stars, in some cases perhaps with catastrophic consequences for planetary systems due to processes such as atmospheric erosion and depletion. Despite their importance, the direct observational evidence for stellar CMEs is almost non‐existent. In this way, numerical simulations constitute extremely valuable tools to shed some light on eruptive behavior in the stellar regime. Here, we review recent results obtained from realistic modeling of CMEs in active stars, highlighting their key role in the interpretation of currently available observational constraints. We include studies performed on M‐dwarf stars, focusing on how emerging signatures in different wavelengths related to these events vary as a function of the magnetic properties of the star. Finally, the implications and relevance of these numerical results are discussed in the context of future characterization of host star‐exoplanet systems.
