Authors: El-Shazly Ehab A. A. , Moussa Saber I. , Dakroury Gehan A. 
Published: April 2022

AbstractIn this work, graphene oxide (GO), prepared using the Hummers method, is physically characterized and used for rare-earth metals recovery from monazite ores. Batch study for sorption of 152+154Eu radionuclide onto GO carried out to assess the optimum reaction parameters for recovery process. The optimum pH is 2.09, the equilibrium time achieved after 5 h, humic acid enhances the sorption efficiency but if its concentration increases it opposes the sorption process. The kinetic reaction mechanism is regulated by pseudo-2nd order and the sorption isotherms show Langmuir applicability. The maximum sorption capacity for 152+154Eu at 20 °C is 59.81 mg g−1. Desorption studies were performed to determine a proper eluent with a suitable concentration for the recovery process and 0.1 M HCl was selected as an efficient eluent. The sorption process is favorable and endothermic. Finally, GO is used as a sorbent for rare-earth elements accumulated in monazite ore. The sorption efficiency of REE is 69.03% with initial concentration 1149.57 mg L−1 at monazite leachate and the recovery percentage is 20.32%. These results promised the use of GO for REE recovery from monazite ore.

Published: April 2022

AbstractAdditive manufacturing (AM) technologies, generally called 3D printing, are widely used because their use provides a high added value in manufacturing complex-shaped components and objects. Defects may occur within the components at different time of manufacturing, and in this regard, non-destructive techniques (NDT) represent a key tool for the quality control of AM components in many industrial fields, such as aerospace, oil and gas, and power industries. In this work, the capability of active thermography and eddy current techniques to detect real imposed defects that are representative of the laser powder bed fusion process has been investigated. A 3D complex shape of defects was revealed by a µCT investigation used as reference results for the other NDT methods. The study was focused on two different types of defects: porosities generated in keyhole mode as well as in lack of fusion mode. Different thermographic and eddy current measurements were carried out on AM samples, providing the capability to detect volumetric irregularly shaped defects using non-destructive methods.

Key Summary Points
Aim
What effect does a novel education programme have on emergency hospital transfers of, and advance care planning decisions among, nursing home residents?

Findings
This education programme did not affect overall rates of emergency hospital transfer. It did increase advance care planning discussions, increase compliance with the results of these discussions and increase “DNR” orders among nursing home residents.

Message
Novel tele-education programmes have the potential to improve advance care planning discussions in nursing homes.
Modeling and Analyzing the Dynamical Motion of a Rigid Body with a Spherical Cavity
Authors: Farag A. M. , Amer T. S. , Abady I. M. 
Published: April 2022

AbstractThe rotatory motion of a rigid body having a cavity, close to a spherical form, filled with a viscous incompressible fluid around its center of mass is investigated. It is assumed that the Reynolds number has a modest restricted value due to the high velocity of the fluid. The body rotates under the influence of a viscous fluid besides the action of a gyrostatic moment vector about the principal axes of the body. The governing system of motion is derived and the averaging of the Cauchy problem of this system is analyzed. The analytic solutions are derived through several transformations and plotted graphically to demonstrate the positive influence of the physical body's parameters on the motion. The stability of these solutions is examined through their phase plane diagrams. In light of the efficiency of a gyrostatic moment on the considered motion, new results of this work have been achieved. The significance of this work stems from its numerous uses in everyday life, particularly in vehicles that hold liquids, such as aircraft, submarines, ships, and other vehicles. Moreover, it is also used in engineering applications that depend on the gyroscopic theory.

AbstractScientific study of issues at the nexus of food–energy–water systems (FEWS) requires grappling with multifaceted, “wicked” problems. FEWS involve interactions occurring directly and indirectly across complex and overlapping spatial and temporal scales; they are also imbued with diverse and sometimes conflicting meanings for the human and more-than-human beings that live within them. In this paper, we consider the role of language in the dynamics of boundary work, recognizing that the language often used in stakeholder and community engagement intended to address FEWS science and decision-making constructs boundaries and limits diverse and inclusive participation. In contrast, some language systems provide opportunities to build bridges rather than boundaries in engagement. Based on our experiences with engagement in FEWS science and with Indigenous knowledges and languages, we consider examples of the role of language in reflecting worldviews, values, practices, and interactions in FEWS science and engagement. We particularly focus on Indigenous knowledges from Anishinaabe and the language of Anishinaabemowin, contrasting languages of boundaries and bridges through concrete examples. These examples are used to unpack the argument of this work, which is that scientific research aiming to engage FEWS issues in working landscapes requires grappling with embedded, practical understandings. This perspective demonstrates the importance of grappling with the role of language in creating boundaries or bridges, while recognizing that training in engagement may not critically reflect on the role of language in limiting diversity and inclusivity in engagement efforts. Leaving this reflexive consideration of language unexamined may unknowingly perpetuate boundaries rather than building bridges, thus limiting the effectiveness of engagement that is intended to address wicked problems in working landscapes.
Reconsidering the role of place in health and welfare services: lessons from the COVID-19 pandemic in the United States and Canada

Published: April 2022

AbstractPlaces—the meaningful locations of daily life—have been central to the wellbeing of humans since they first formed social groups, providing a stable base for individuals, families, and communities. In the United States and Canada, as elsewhere, place also plays a foundational role in the provision of critical social and health services and resources. Yet the globally destabilizing events of the COVID-19 pandemic have dramatically challenged the concept, experience, and meaning of place. Place-centered public health measures such as lockdowns and stay-at-home orders have disrupted and transformed homes, neighborhoods, workplaces, and schools. These measures stressed families and communities, particularly among marginalized groups, and made the delivery of vital resources and services more difficult. At the same time, the pandemic has stimulated a range of creative and resilient responses. Building from an overview of these effects and drawing conceptually on theories of people–place relationships, this paper argues for critical attention to reconsidering and re-envisioning prevailing assumptions about place-centric policies, services, and practices. Such reappraisal is vital to ensuring that, going forward, scholars, policymakers, and practitioners can effectively design and deliver services capable of maintaining social connections, safety, and wellbeing in contexts of uncertainty, inequality, and flux.
Effect of High-Intensity Intermittent Hypoxic Training on 3-on-3 Female Basketball Player’s Performance
Authors: Smith H. K. , Hamlin M. J. , Elliot C. A. 
Published: April 2022

Abstract
Purpose
To investigate the effects of 4 weeks high-intensity interval training in hypoxia on aerobic and anaerobic performance of 3-on-3 basketball players.

Methods
In a randomised controlled trial, 15 female basketballers completed eight 1-h high-intensity training sessions in either normobaric hypoxia (hypoxic group n = 8, altitude 3052 m) or normoxia (normoxic group n = 7, sea-level).

Results
After training, the hypoxic group increased their 1-min all-out shuttle run distance by 2.5% ± 2.3% (mean ± 95% CI, d = 0.83, P = 0.04), compared to the normoxic group 0.2% ± 2.3% (d = 0.06, P = 0.8), with the difference between groups being clinically worthwhile but not statistically significant (d = 0.77, P = 0.1). Distance covered in the Yo-Yo intermittent recovery test tended to increase in the hypoxic (32.5% ± 39.3%, d = 1.0, P = 0.1) but not normoxic group (0.3% ± 24.5%, d = 0.08, P = 0.9), with a non-significant change between groups (d = 0.9, P = 0.2). Compared to normoxia, the hypoxic group significantly increased subjective markers of stress (d = 0.53, P = 0.005), fatigue (d = 0.43, P = 0.005), and muscle soreness (d = 0.46, P = 0.01), which resulted in a lower perceived training performance in the hypoxic compared to the normoxic group (d = 0.68, P = 0.001).

Conclusion
High-intensity interval training under hypoxic conditions likely improved 1-min all-out shuttle run ability in female basketball 3-on-3 players but also increased subjective markers of stress and fatigue which must be taken into consideration when prescribing such training.
Measuring and evaluating CSR information and involvement strategies on corporate Facebook pages
Authors: Amabile Sara , Conte Francesca , Vollero Agostino , Siano Alfonso 
Published: April 2022

AbstractOrganizations are increasingly involving stakeholders in their CSR activities through social networks. Despite the growing interest by academics and practitioners in this field of research, empirical studies are still limited, highlighting a gap in the identification and the use of effective measurement tools for evaluating sustainable marketing performances on social networks. The study aims to develop a framework to measure and assess stakeholder engagement strategies, in terms of CSR information and involvement, on Facebook pages of sustainable organizations. The framework is based on a set of dimensions (macro-item, item and micro-item) and adopts different types of variables (dichotomous and indices) and techniques (manual detection, Facebook developers tools, content analysis through the NooJ, and Likealyzer). A pilot study on firms classified by the Dow Jones Sustainability World Index (2015) confirms the applicability of the framework, showing that organizations prefer a “one-way” communication approach (CSR information strategies), rather than a “two-way” communication approach (CSR involvement strategies). The framework constitutes a tool aimed at analyzing and measuring the CSR communication strategies on corporate Facebook pages. It provides managers and consultants of digital communication useful indications to improve sustainable marketing activities and stakeholder engagement strategies on Facebook.
Valorization of poly-β-hydroxybutyrate (PHB)-based bioplastic waste in anaerobic digesters of food waste for bioenergy generation: reactor performance, microbial community analysis, and bioplastic biodegradation
Authors: Zhang Le , Tsui To-Hung , Fu Jiahua , Dai Yanjun , Tong Yen Wah 
Published: April 2022

AbstractThis study aims to investigate the significance and biodegradation pathways of PHB-based bioplastic in anaerobic digesters treating food waste, where the reactor performance of changed methane generation, bioplastic biodegradation efficiency, and bioinformatic analysis of functional microbes were emphasized. The results showed that PHB-based plastic film could be partially biodegraded in the food waste digester, and a bioaugmentation use of Alcaligenes Faecalis (AF) and Bacillus Megaterium (BM) was beneficial to largely accelerate the degradation process through a beneficial shift of both the functional bacterial and archaeal species. Microbial community analysis indicated that the major bacterial species belonged to genera Candidatus_Cloacimonas, Rikenellaceae, and Defluviitoga, while the dominant methanogenic archaeal species belonged to genera Methanomassiliicoccus, Methanosarcina, and Methanosaeta. Bioplastic biodegradation analysis suggested that the optimal fractions of AF and BM for PHB-based plastic degradation were 50%AF and 75%BM, respectively, which deserves further optimization and scale-up validation. The finding of this study would contribute to the combined management of PHB-based bioplastic with food waste for clean energy recovery and a greener environment.
Climate policy uncertainty and corporate investment: evidence from the Chinese energy industry
Authors: Ren Xiaohang , Shi Yukun , Jin Chenglu 
Published: April 2022

AbstractIn recent years, with the increasing attention paid to climate risks, the changes in climate policies are also more full of uncertainties, which have brought tremendous impact to economic entities, including companies. Using the dynamic threshold model, this study investigates the nonlinear and the asymmetric effect of climate policy uncertainty on Chinese firm investment decisions with panel data of 128 Chinese energy-related companies from 2007 to 2019. The empirical findings indicate that the influence of climate policy uncertainty on firm investment is significantly nonlinear. Overall, climate policy uncertainty is not apparently related to corporate investments in the high-level range, while it negatively affects the investments in the low-level range. In addition, to be more specific, the negative impact of climate policy uncertainty on the mining industry is tremendous, while the influence on the production and supply of electricity, heat, gas, and water sector is remarkably positive. The results of this study could help the company managers and policymakers to arrange appropriate related strategies under different climate policy conditions.
Pudendal Neuromodulation is Feasible and Effective After Pudendal Nerve Entrapment Surgery
Authors: Meier Kristen M. , Vecellio Patrick M. , Killinger Kim A. , Boura Judith A. , Peters Kenneth M. 
Published: April 2022

ABSTRACTBackgroundPatients with intractable pain in the pudendal nerve distribution may benefit from pudendal neuromodulation; however, some may have previously undergone pudendal nerve entrapment surgery (PNES), potentially altering nerve anatomy and function.AimWe examined pudendal neuromodulation outcomes in patients with prior PNES.MethodsPatients with a history of PNES and quadripolar, tined pudendal lead placement for urogenital pain were reviewed. Symptoms and outcomes were collected from existing medical records.OutcomesPatients with pudendal neuromodulation and prior PNES were compared to patients with no prior PNES who had pudendal lead placement.ResultsFifteen patients with a history of 1, 2, or 3 prior PNES (n = 13, 1, and 1, respectively) were evaluated. Most (10; 67%) were female, with bilateral pain (9; 60%), and symptoms of 5–26 years. After trialing the lead, bladder symptoms and pain were improved in 8 of 12 and 9 of 14 patients, respectively, and 80% of patients (12/15) underwent permanent generator implantation. When prior PNES patients were compared to those with no prior PNES (n = 43), gender (67% vs 77% female; P = .50) and age (median 63 vs 58 years; P = .80), were similar; however, BMI differed (mean 24 vs 29; P = .008) and a lower proportion (12/15; 80% vs 42/43; 98%; P = .049) had generator implantation. Importantly, median lead implant time (48 vs 50 minutes; P = .65) did not differ between the 2 groups.Clinical ImplicationsPudendal neuromodulation has the potential to provide pain relief for a very difficult-to-treat population; furthermore, it does not appear that prior PNES surgery made lead placement significantly more challenging.Strengths & LimitationsStudy strengths include being a tertiary referral center for urogenital pain and having a single surgeon perform all procedures in a regimented way. Limitations include the retrospective study design, small sample size and various approaches to PNConclusionChronic pudendal neuromodulation can be a viable option even after prior PNES.
The 19th-century Slovak National Movement: Ethos of Plebeian Resistance
Authors: Gluchman Vasil 
Published: April 2022

AbstractThe author studies the 19th-century Slovak National Movement as a manifestation of the ethos of plebeian resistance against the “laws of progress” of the century in question, according to which small ethnic groups and nations were to be assimilated for the sake of the further development of more advanced nations and their cultures. A significant role in the formation of the ethos of plebeian resistance was played by Slovak folk culture, the historical context of Great Moravia, the solidarity and support of other Slavic nations living in the Habsburg monarchy, and, above all, the moral qualities of Slovak patriots. Among the most significant manifestations of this ethos was the codification of Slovak, which contributed to the formation of Slovak national identity and national ideology, the 1848–1849 Slovak Uprising, and the development of the Slovak national movement in the 1860s continuing into the mid-1870s. The aim of the 19th-century Slovak national movement was to achieve an equal position of the Slovak ethnic group among the other nations and ethnic groups living in the Habsburg monarchy, which would give rise to the free development of its creative powers and abilities as well as to the pursuit of ethical, humanistic ideals in the lives of its members.
Einsteinian language: Max Talmey, Benjamin Lee Whorf and linguistic relativity
Authors: Gordin Michael D. 
Published: April 2022

AbstractThis paper explores the significant – albeit little-known – impact that physicist Albert Einstein's theory of relativity had on the development of the science of linguistics. Both Max Talmey, a physician who played a key role in the development of early twentieth-century constructed-language movements, and Benjamin Lee Whorf, who is closely associated with the notion of ‘linguistic relativity’, drew on their understanding of relativity to develop their ideas (and, in Talmey's case, also on his personal relationship with Einstein). Linguistic relativity, which posits that humans’ linguistic categories shape their perceptions of nature, has often been tied to ‘relativism’ in the social sciences and humanities. In contrast, Talmey's commitment to reformulating the language of Einsteinian relativity – especially through a constructed language he built in the 1920s and 1930s – emphasized the significance of ‘invariance’ simultaneously in the scientific doctrine and in the language in which it was discussed. The semiotic flexibility of Einstein's ‘relativity theory’ as it was widely (and wildly) appropriated outside the small community of theoretical physicists enabled the two opposing moves, while obscuring the historical linkage between physics and linguistics for both.
Role of fluids on deformation in mid-crustal shear zones, Raft River Mountains, Utah
Authors: Gottardi Raphaël , Hughes Brendan 
Published: April 2022

AbstractFluids are commonly invoked as the primary cause for weakening of detachment shear zones. However, fluid-related mechanisms such as pressure-solution, reaction-enhanced ductility, reaction softening and precipitation of phyllosilicates are not fully understood. Fluid-facilitated reaction and mass transport cause rheological weakening and strain localization, eventually leading to departure from failure laws derived in laboratory experiments. This study focuses on the Miocene Raft River detachment shear zone in northwestern Utah. The shear zone is localized in the Proterozoic Elba Quartzite, which unconformably overlies the Archaean basement, and consists of an alternating sequence of quartzite and muscovite-quartzite schist. In this study, we characterize fluid-related microstructures to constrain conditions that promoted brittle failure in a plastically deforming shear zone. Thin-section analyses reveal the presence of healed microcracks, transgranular fluid inclusion planes and grain boundary fluid inclusion clusters. Healed microcracks occur in three sets, one sub-perpendicular to the mylonitic foliation, and a set of two conjugate microcracks oriented at ∼40–60° to the mylonitic foliation. Healed microfractures are filled with quartz, which has a distinct fabric, suggesting that microcracks healed while the shear zone was still at conditions favourable for quartz crystal plasticity. Transgranular fluid inclusion planes also occur in three sets, similar in orientation to the healed microfractures. Fluid inclusions commonly decorate grain and subgrain boundaries as inter- and intragranular clusters. Our results document ductile overprint of brittle microstructures, suggesting that, during exhumation, the Raft River detachment shear zone crossed the brittle–ductile transition repeatedly, providing pathways for fluids to permeate through this shear zone.
Collateral Constraints, Financial Constraints, and Risk Management: Evidence From Anti-Recharacterization Laws
Authors: Fairhurst Douglas (DJ) , Nam Yoonsoo 
Published: April 2022

AbstractWe use the staggered enactment of anti-recharacterization laws as a plausibly exogenous shock to the value of securitizing collateral through special purpose vehicles (SPVs) and test how collateral values impact corporate risk management. Following the laws’ enactment, we find increases in commodity, foreign exchange, and interest rate hedging, especially for firms with exposure to these risks and that rely on SPVs. Supporting the collateral constraints literature, the effect is weaker for firms that likely need the collateral for external financing, such as financially constrained firms. Our findings highlight fluctuations in collateral values as an important consideration in risk management decisions.
