The increasing global market size of high-energy storage devices due to the boom in electric vehicles and portable electronics has caused the battery industry to produce a lot of waste lithium-ion batteries. The liberation and de-agglomeration of cathode material are the necessary procedures to improve the recycling derived from spent lithium-ion batteries, as well as enabling the direct recycling pathway. In this study, the supercritical (SC) CO2 was innovatively adapted to enable the recycling of spent lithium-ion batteries (LIBs) based on facilitating the interaction with a binder and dimethyl sulfoxide (DMSO) co-solvent. The results show that the optimum experimental conditions to liberate the cathode particles are processing at a temperature of 70 °C and 80 bar pressure for a duration of 20 min. During the treatment, polyvinylidene fluoride (PVDF) was dissolved in the SC fluid system and collected in the dimethyl sulfoxide (DMSO), as detected by the Fourier Transform Infrared Spectrometer (FTIR). The liberation yield of the cathode from the current collector reaches 96.7% under optimal conditions and thus, the cathode particles are dispersed into smaller fragments. Afterwards, PVDF can be precipitated and reused. In addition, there is no hydrogen fluoride (HF) gas emission due to binder decomposition in the suggested process. The proposed SC-CO2 and co-solvent system effectively separate the PVDF from Li-ion battery electrodes. Thus, this approach is promising as an alternative pre-treatment method due to its efficiency, relatively low energy consumption, and environmental benign features.

COVID-19 elicited a rapid emergence of new mutual aid networks in the US, but the practices of these networks are understudied. Using qualitative methods, we explored the empirical ethics guiding US-based mutual aid networks\' activities, and assessed the alignment between principles and practices as networks mobilized to meet community needs during 2020-21. We conducted in-depth interviews with 15 mutual aid group organizers and supplemented these with secondary source materials on mutual aid activities and participant observation of mutual aid organizing efforts. We analyzed participants\' practices in relation to key mutual aid principles as defined in the literature: 1) solidarity not charity; 2) non-hierarchical organizational structures; 3) equity in decision-making; and 4) political engagement. Our data also yielded a fifth principle, \"mutuality,\" essential to networks\' approaches but distinct from anarchist conceptions of mutualism. While mutual aid networks were heavily invested in these ethical principles, they struggled to achieve them in practice. These findings underscore the importance of mutual aid praxis as an intersection between ethical principles and practices, and the challenges that contemporary, and often new, mutual aid networks responding to COVID-19 face in developing praxis during a period of prolonged crisis. We develop a theory-of-change model that illuminates both the opportunities and the potential pitfalls of mutual aid work in the context of structural inequities, and shows how communities can achieve justice-oriented mutual aid praxis in current and future crises.

Despite prior publications of clinical practice guidelines related to ventilator liberation, some questions remain unanswered. Many of these questions relate to the details of bedside implementation. We, therefore, formed a guidelines committee of individuals with experience and knowledge of ventilator liberation as well as a medical librarian. Using Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology, we make the following recommendations: (1) We suggest that calculation of a rapid shallow breathing index is not needed to determine readiness for a spontaneous breathing trial (SBT) (conditional recommendation; moderate certainty); (2) We suggest that SBTs can be conducted with or without pressure support ventilation (conditional recommendation, moderate certainty); (3) We suggest a standardized approach to assessment and, if appropriate, completion of an SBT before noon each day (conditional recommendation, very low certainty); and (4) We suggest that FIO2 should not be increased during an SBT (conditional recommendation, very low certainty). These recommendations are intended to assist bedside clinicians to liberate adult critically ill patients more rapidly from mechanical ventilation.

UNASSIGNED: Diversity, equity, and inclusion, also known as DEI, is an essential topic being discussed across society. The field of environmental health (EH) should certainly not be excluded from the conversation.
UNASSIGNED: The purpose of this mini-review was to map the literature and identify gaps on the topic of DEI in the EH workforce.
UNASSIGNED: A rapid scoping review was conducted using standard synthesis science methods to search and map the published literature. All study titles, abstracts, and full texts were screened by 2 independent reviewers among the authorship team.
UNASSIGNED: The search strategy yielded 179 English language papers. Of those, 37 met all inclusion criteria after full text screening. Overall, the majority of the articles had weak or moderate DEI engagement and only 3 articles had strong DEI engagement.
UNASSIGNED: There is a significant need for additional research in this realm. Future studies should explicitly focus on workforce issues, and attempt to achieve the highest level of the evidence possible for this field.
UNASSIGNED: Although DEI initiatives are a step in the right direction, the current evidence suggests that inclusivity and liberation may prove to be more impactful and meaningful constructs to fully advance equity in the EH workforce.

Strengthening character education and positive politeness is an important pillar in selecting textbooks and teaching materials in global era. This study aimed to identify and describe the prophetic education values in Indonesian language textbooks for the VII grade junior high school in their relation to positive politeness to build students\' character. The research question is \"how are the values of prophetic education as a pillar of politeness and character education in textbooks?\". Descriptive qualitative method was employed as the main approach. Data were collected through documentation using read-marker and noting techniques, and analyzed using heuristic and Grice\'s means-end politeness methods. Furthermore, the data were analyzed using content and comparative document analysis and sharpened by referential pragmatic politeness analysis. The research findings showed several interrelated prophetic education values in relation with the pillars of positive politeness and character education. These values formed the self-sufficiency of students in the Indonesian language textbook of class VII junior high school. They were manifested in the reality oriented to humanization, liberation, and transcendence. Humanization was realized through social life based on the generosity, honesty, tolerance, and politeness values. Similarly, liberation was realized through the education, health, mutual help, and hard work values. Moreover, transcendent life was actualized according to the consistency (istiqamah) in worshipping Allah (swt), gratitude, and humility (tawadhu\') values. This study recommends that prophetic values can be used as a pillar of politeness development and strengthening educational characters in global era.

Clinicians use several measures to ascertain whether individual patients will tolerate liberation from mechanical ventilation, including the rapid shallow breathing index (RSBI).
Given varied use of different thresholds, patient populations, and measurement characteristics, how well does RSBI predict successful extubation?
We searched six databases from inception through September 2019 and selected studies reporting the accuracy of RSBI in the prediction of successful extubation. We extracted study data and assessed quality independently and in duplicate.
We included 48 studies involving RSBI measurements of 10,946 patients. Pooled sensitivity for RSBI of < 105 in predicting extubation success was moderate (0.83 [95% CI, 0.78-0.87], moderate certainty), whereas specificity was poor (0.58 [95% CI, 0.49-0.66], moderate certainty) with diagnostic ORs (DORs) of 5.91 (95% CI, 4.09-8.52). RSBI thresholds of < 80 or 80 to 105 yielded similar sensitivity, specificity, and DOR. These findings were consistent across multiple subgroup analyses reflecting different patient characteristics and operational differences in RSBI measurement.
As a stand-alone test, the RSBI has moderate sensitivity and poor specificity for predicting extubation success. Future research should evaluate its role as a permissive criterion to undergo a spontaneous breathing trial (SBT) for patients who are at intermediate pretest probability of passing an SBT.

The efficient recycling of spent anode material (SAM) from spent lithium-ion batteries (LIBs) is generally critical in terms of electronic waste recyclingas well as increasing resource shortage and environmental problems. This research reported a novel and green method to recycle lithium, copper foil, and graphite from SAM by water leaching treatment. The results indicated that 100% of graphite was exfoliated from the anode material and 92.82% leaching efficiency of lithium was obtained under the optimal conditions of 80 °C, 60 g/L, 300 rpm, and 60 min, respectively. This finding revealed that the SAM got a full liberation characteristic due to the removal of binder, which produced an ideal leaching lithium efficiency rivaling the acids\' performance. The mechanism of the liberation of SAM and lithium leaching is presented based on the analysis of results. The graphite was purified and recovered after water leaching treatment. Besides, lithium was recovered in the form of lithium carbonate (Li2CO3), and the copper foil was recovered in a sheet. This study endeavors to develop an economical and environmentally feasible plan to recycle graphite, copper, and lithium from SAM.

In order to end and \"liberate\" themselves from an abusive relationship, female survivors of intimate partner violence (IPV) usually face a complex process. Although women may decide to seek help through the criminal justice system, some refuse to participate in legal proceedings against their abusers. While many studies have focused on exploring variables explaining disengagement from legal proceedings, the aim of this article is to study the impact of the process of liberation from an abusive relationship on the likelihood of disengagement (LoD) from legal proceedings. Liberation was measured through the psychosocial separation overall score and the LoD was predicted by a logistic regression model developed in a previous study in Spain. A sample of 80 women involved in legal proceedings for IPV against their ex-partners in Andalusia (Spain) participated in this study. Exploratory analyses were conducted using ANOVA and Chi-square; multiple linear regression analyses were used to study the relationship between psychosocial separation and LoD. Results showed that victims who had higher psychosocial separation from their abusers were less likely to disengage from legal proceedings against the abuser. We discuss the results in terms of practical implications like detection of women\'s need for specific psychological support to ease a comprehensive recovery. Training programs for legal professionals and judges in the judicial arena should use the results of this study to increase professionals\' understanding of IPV and survivors\' decision-making processes. This would lead to a decrease in survivors\' secondary victimization, as well as decrease the frustration of legal professionals when victims disengage from legal proceedings.

Proper disposal of spent lithium-ion batteries is beneficial for the resource recycling and pollution elimination. Full liberation of electrode materials, including the liberation between electrode material and current collector (copper/aluminum foils) and the liberation among electrode material particles, is the pivotal precondition for improving the recovery efficiency of electrode materials. In this article, authors attempt to carry out a summary of current technologies used in the liberation of electrode materials derived from spent lithium-ion batteries. However, specialized studies about the liberation of electrode materials are insufficient at present. This research clearly shows that: (1) Organic binder must be removed so as to improve the liberation and metallurgy efficiency of electrode materials; (2) A collaboration of varied technologies is the necessary process to achieve high liberation efficiency between electrode materials and copper/aluminum foils; (3) Pyrolysis may be a recommended technology for removal of organic binder because part of pyrolysis products can be recovered. Finally, an alternative recycling flowchart of spent LIBs is proposed.

Community psychology is expressly concerned with social justice. Such concern necessitates attention to race. Yet, nearly absent from the field\'s literature is explicit and critical attention to whiteness. Thus, community psychology\'s contribution to promoting social justice remains incomplete. In this article, we examine how a critical construction of whiteness can be useful for community research and action. After a brief history of the construction of whiteness in the United States, and a summary of key insights from critical whiteness studies, we present a scoping review of the nascent body of community psychology literature that addresses whiteness. That work implicates whiteness in the emergence of the field itself, frames whiteness as social location, problematizes whiteness, addresses White supremacy and institutional racism, interrogates White privilege, and employs whiteness as a theoretical standpoint. We conclude with three propositions for scholars to broker the relationship between community psychology and critical whiteness studies: (a) community psychology should become more critically conscious of whiteness, (b) community psychologists should promote critical awareness of the ways that whiteness operates as a complex system, and (c) greater critical awareness of whiteness should be applied to the development of multilevel interventions aimed at dismantling whiteness as a system of domination.
