Brazil hosts the second-largest rare earth element (REE) resources worldwide, with important LREE (monazite) deposits, associated with heavy minerals as placer deposits or with alkaline-carbonatitic deposits. The latter represent a considerable technological challenge in exploiting REEs due to their frequently fine (<10 mu m) grain size. Therefore, it is imperative to improve and create new techniques and procedures to assure the economic feasibility of these resources. Chemical analysis, X-ray diffraction, scanning electron microscopy and mineral liberation analysis were performed on two different samples with low and high LREE contents from Catal & atilde;o (Goi & aacute;s, Brazil). All the results presented herein are thus a necessary first step to develop concentration test protocols to improve monazite recovery during mineral processing. According to these mineralogical results, the monazite's concentration might make recovery feasible despite its fine-grained size. MLA showed that barite is mainly concentrated in the coarser size fractions for both samples, whereas monazite is liberated below 75 mu m for low-grade ore and below 150 mu m for high-grade ore, suggesting that a sieving procedure could reduce it to nearly 30%-50% of the total mass of the samples, with barite and quartz reduction from 53% to 57% and 54%-65%, respectively.
Objective: to evaluate the profile of women attended in gynaecological nursing consultations within the context of primary health care. Methods: this cross-sectional, analytical study conducted through the analysis of 135 medical records of wo-men aged 25-64 years who underwent gynaecological nursing consultations. A validated instrument was used for data col-lection. Data were analysed using descriptive and inferential approaches. Results: adult, married women with low educational levels predominated, mostly engaged in domestic work and with income considered sufficient. Chronic diseases, family conflicts, frequent religious practice, and high adherence to contraceptive methods were identified, contrasting with low use of dual protection and limited knowledge about cervical cancer screening. Considerable gaps in the records of family and sexual violence, as well as a high proportion of incomplete data, were observed. Conclusion: the identified profile reveals social and health vulnerabilities that impact women's care and highlights the need for educational strategies, sensitive care, and a comprehensive approach. Contributions to practice: the study supports improvements in care processes, enhances the use of standardised instruments, and strengthens the role of nurses in promoting comprehensive, equitable, women-centred care based on their real needs.
Objective: to develop and validate the content and appearance of a booklet for American football players, focusing on the recognition, prevention, and management of concussion. Methods: this is a methodological study conducted in three stages for the development and validation of a booklet. The panel of evaluators consisted of six experts selected through snowball sampling. Data collection was performed using the Health Educational Content Validation tool and the Appearance Validation of Health Educational Technologies tool. Data analysis was performed using the content and appearance validity index, with a value equal to or greater than 0.80. Results: six experts participated in the study. Regarding the overall content validity index, the material achieved 0.98. The experts' suggestions were incorporated into the final version of the booklet. Conclusion: this informational resource in booklet format is adequate in terms of content and appearance, strengthening the understanding of preventive measures and concussion management, thereby contributing to a safer sporting environment. Contributions to practice: the material strengthens nursing practice by providing clear and reliable educational support focused on athlete health.
Philodryas nattereri is a dipsadid snake widely distributed in South America. Although it is a wellknown species regarding its diet, only a small portion of the records are related to observations in the natural environment, resulting in a lack of information about its predatory behavior. The predation records were mainly obtained through the citizen science platform iNaturalist and investigated before inclusion. The results are consistent with other studies, corroborating that P. nattereri has a generalist diet. We have added three new prey-predator interactions for P. nattereri, as well as confirming for the second time its cannibalism. These records expand the knowledge on its ecology and predation behavior, with significant implications for understanding ecological processes in areas where P. nattereri occurs. Furthermore, the benefits of citizen science are emphasized as a valuable tool for gathering information about biodiversity, highlighting the role of citizens in contributing to the advance of biological scientific knowledge.
This paper develops a relational perspective in the philosophy of chemistry. It argues that chemical entities should not be understood as self-subsistent substances endowed with fixed intrinsic properties, but as historically situated and processual realities whose identities emerge through networks of relations. These relations are not limited to intramolecular interactions, but also involve experimental practices, representational tools, technological infrastructures, environmental conditions, social uses, and temporal trajectories. Grounded in Whitehead's process philosophy and in contributions from Schummer, Bensaude-Vincent and Harr & eacute;, the paper proposes a threefold framework of relationality: ontological, epistemological, and socio-environ mental. At the ontological level, chemical substances are conceived as nodes in dynamic networks of reactivity and transformation; at the epistemological level, chemical knowledge is shown to depend on situated practices of modeling, experimentation, and representation; at the socio-environmental level, chemical entities acquire multiple modes of existence beyond the laboratory. The case of amphetamines illustrates how chemical substances are created, stabilized, circulated, and transformed within scientific, industrial, cultural, and ecological contexts. The paper concludes that a relational philosophy of chemistry offers a more adequate framework for understanding the contingency, plurality, and ethical implications of chemical entities in the world.
