Reescriptures del mite de la dona d’aigua en la cançó contemporània
Authors: Hernàndez-i-Garcia Xavier 
Published: January 2025

El mite de la dona d’aigua és una part essencial del nostre patrimoni etnopoètic. Arreu dels Països Catalans trobem llegendes sobre aquests éssers fantàstics, també anomenades encantades, goges, nimfes o fades. L’aigua hi és vista com un element generador de vida i, per tant, associat a la fertilitat, l’exuberància, el misteri i la sensualitat. Les dones d’aigua són d’una gran bellesa i guarden tresors meravellosos, però també poden ser perilloses per als humans. El mite ha arribat a l’actualitat en múltiples versions i ha sigut incorporat a la literatura per autors com Jacint Verdaguer, Josep Sebastià Pons, Miquel Costa i Llobera o Miquel Martí i Pol. A partir dels anys seixanta, en l’àmbit de la cançó, trobem adaptacions d’aquests textos fetes per cantautors com Teresa Rebull, Maria del Mar Bonet o Marala. Paral·lelament, grups de folk com Xaloc Música o Nou Romancer han musicat les rondalles tradicionals en què apareixen aquests éssers. En els darrers anys, tanmateix, és quan sorgeixen reescriptures més lliures del mite, que han fet grups com La Gossa Sorda, Clara Peya o Txell Sota, i que hi aporten una visió feminista en què aquesta criatura és vista com un exemple de dona lluitadora, lliure i empoderada.
Revisió del concepte de bruixa a partir de les llegendes menorquines
Authors: Pérez i Pérez Lidia 
Published: January 2025

El concepte de bruixa, que sovint encapçala moviments feministes, ha tengut molta controvèrsia al llarg dels segles, des del seu naixement fins avui dia, i molta gent no coneix quin en va ser el context, ni la repercussió, ni les conseqüències que ens han arribat. Al llarg del segle xvi, la concepció de bruixa incloïa intrínsecament que la dona encarnava el mal. Eren, per tant, dones i sovint de classe baixa: eren oprimides que es resistien a la pobresa i a l’exclusió social; per això foren les protagonistes d’un ampli moviment polític en què crearen una societat organitzada, anàrquica i antisocial que era rebuda com una conspiració contra la civilització, la qual cosa fou un dels pretextos que usaren per dur a terme la cacera. A Menorca, hi va haver un cas registrat d’assassinat, el de Joana Gonyalons, que era la tercera del signe Escorpí de la família: padrina, mare i neta compartien el mateix signe i totes tres van ser acusades de ser bruixes. Durant el segle xviii, amb la pujada al tron de Felip v i sobretot amb l’arribada dels anglesos a l’illa i l’eliminació del Tribunal del Sant Ofici, es començà a estendre la por cap a les bruixes. Aquest sentiment es canalitzà, com és natural, a través de les llegendes.
VIDA, TRABALHO E PAPÉIS SOCIOESPACIAIS DAS MULHERES A PARTIR DA MIGRAÇÃO RURAL-URBANA NO MUNICÍPIO DE MUZAMBINHO-MG
Authors: Almeida Araújo Letícia , Do Vale Ana Rute 
Published: January 2025

Quando vivem no campo, geralmente, as mulheres não possuem o reconhecimento e valorização de seu trabalho, sendo que seus papéis socioespaciais ficam restritos à esfera reprodutiva do lar e acabam buscando, na cidade, uma situação diferente. A partir do caso das mulheres que viveram no campo e depois migraram para a cidade, no município de Muzambinho-MG, essa pesquisa buscou compreender se seus papéis socioespaciais e as relações de trabalho se alteraram a partir do momento que passaram a viver no espaço urbano. Partindo de entrevistas com mulheres do campo e migrantes da cidade, pode-se concluir que, no contexto da realidade de uma cidade pequena, permeada pela ruralidade, a busca por melhores condições de vida na cidade foi, de certa forma concretizada, embora ainda vivenciem papéis socioespaciais desiguais, especialmente, pelos postos ocupados com menor remuneração e pela responsabilidade integral do trabalho reprodutivo
Existing and Promising Technologies for Hydrogen Sulfide Decomposition into Hydrogen and Sulfur
Authors: Zagoruiko A. N. , Kondrashev D. O. , Popov M. V. , Kleymenov A. V. 
Published: January 2025

Hydrogen sulfide is a very attractive raw material for the production of hydrogen. The dissociation energy of H2S (21 kJ/mol at room temperature) is much lower than that of water (286 kJ/mol) or even hydrocarbons (76 kJ/mol for methane); moreover, the hydrogen bond energy in the H2S molecule is the lowest among all natural hydrogen compounds.However, hydrogen sulfide has not yet found widespread industrial use as a raw material for hydrogen production. The main obstacle to the creation of an effective technology for this purpose is the very strict thermodynamic limitations of the reaction of hydrogen sulfide decomposition into elements H2S Û S + Н2 – Q.This review is devoted to the analysis of the known approaches to the production of hydrogen and sulfur from hydrogen sulfide, their shortcomings that cause the failure of the previously proposed technologies, as well as the ways of possible creation of effective processes for this purpose. The review focuses on non-stationary cyclic processes, which can be considered one of the most promising ways to create an effective H2S decomposition technology.

Published: January 2025

Summary
Hydraulic fracturing is an effective method for enhancing both the initial reservoir production and ultimate recovery. Nevertheless, the conductivity of proppant fractures is a pivotal factor in the optimization of fracture designs within the context of fracture modification. Experimental testing methods for proppant fracture conductivity are costly and time-consuming, and the physical model is excessively complex and incomplete to account for all the influencing factors, resulting in low computational efficiency. A backpropagation neural network (BPNN) model was constructed using the RAdam optimization algorithm to identify a more efficacious method for predicting the conductivity of proppant fractures. The model was used to predict the fracture conductivity of two data types pertaining to the experimental data on the conductivity of geothermal and volcanic reservoirs. The prediction model is enhanced for three key areas. First, an isolated forest algorithm is used to assess and discard anomalous data points. Second, the objective function is optimized by employing the RAdam optimization algorithm, which has the advantages of both Adam and stochastic gradient descent (SGD). This guarantees rapid convergence and prevents the initial training phase from converging to a locally optimal solution. Moreover, this approach enhances the stability of the model training process. Finally, the rectified linear unit (ReLU) activation function may result in issues related to neuronal activity, including the potential for its disappearance. This study addresses this problem by employing the Kaiming initialization method. The experiments used a series of evaluation metrics, including the mean square error and coefficient of determination, to assess the predictive performance of the two data sets in the two distinct models. The experimental results indicate that the BPNN with RAdam optimization is a more effective approach for data pertaining to volcanic and geothermal reservoirs. Moreover, the prediction of the geothermal reservoir data is more precise than that of the volcanic reservoir data. This model can be used for rapid predictions based on existing fracture conductivity data, which can better guide the design of fracture modifications and is of great importance.

Published: January 2025

Summary
Efficiency and quality have always been the focus of coring operations. This paper proposes a new method of resonance coring to solve the problems of slow penetration rate, poor quality, and low efficiency when coring in deep formations. First, a stress field distribution model of rock under resonance coring conditions is developed in the paper, which specifies the magnitude of the force at any location inside the rock. Then, a 3D numerical simulation for resonance coring with the full-size drill bit is conducted based on indoor resonance coring experiments. Subsequently, a 2D numerical simulation on a single-tooth resonantly cutting rock is carried out by embedding a zero-thickness cohesive element globally. Finally, the resonance coring speedup mechanism is investigated from the perspectives of lithology, load form, and dynamic load characteristics, respectively. Based on the analysis undertaken, it can be concluded that the resonance coring method is feasible in principle. The harmonic dynamic load can aggravate the damage and the fracture degree of rock under the coring bit as well as the stress field on the surface of the core. The particle size of cuttings is larger and the proportion of tensile fracture of rock is increased by the combination of static and dynamic loads. The increase in frequency and amplitude of dynamic load is beneficial to promote the penetration rate of resonance coring. It is possible to improve coring efficiency without compromising core quality and wellbore integrity by optimizing the combination of static and dynamic loads. The study provides a new solution for efficient coring in deep and complex formations.
Revolutionizing High-Pressure Well Cementing: Enhancing Geopolymer Cement with Laponite for Sustainable and Sedimentation-Free Applications
Authors: Abdelaal Ahmed , Elkatatny Salaheldin 
Published: January 2025

Summary
Sustainable geopolymer cement emerges as a prospective substitute to traditional Portland cement systems in the petroleum industry. Geopolymers offer different advantages over Portland cement, including reduced carbon emissions due to lower energy requirements during production, improved durability and chemical resistance, and the ability to use industrial byproducts as raw materials. This technology promotes sustainable waste management practices while maintaining high performance in various applications. This research aims to explore and maximize the geopolymer technology potential by addressing the issue of sedimentation in high-pressure well cementing applications. By incorporating Laponite particles into hematite-based Class F fly ash (FFA) geopolymer cement formulations, a solution is presented to mitigate sedimentation problems and ensure homogeneity and density uniformity along cement columns. Through the application of American Petroleum Institute (API) and non-API techniques, this study uncovers the remarkable benefits of Laponite in mitigating sedimentation problems and enhancing key characteristics such as strength and rheological properties. The findings reveal that Laponite-based geopolymer systems exhibit improved yield point (YP) and gel strength (GS), as well as reduced porosity and density variation. Adding 3% by weight of FFA of Laponite to the cement formulation reduced the density difference between cement sections from 39.38% when no Laponite was present in the system to only 0.58%. Additionally, the measured elastic properties indicate enhanced flexibility compared with Portland cement systems.
By determining the optimal Laponite concentration, this study achieves a step forward in promoting sedimentation-free and environmentally friendly non-Portland cementing methods in the petroleum industry.

Published: January 2025

Abstract

Although artisanal mining is dominant in the Pan-African Mineral Belt in North-Central Nigeria, there are no known reports of studies detailing the mineralization, type of mineral occurrences, and processes controlling the mineralization in the area. This study aimed to conduct a geochemical evaluation of stream sediment heavy mineral fractions to understand the mineral ore characteristics. The adopted methodology involved delineating the study area based on potential mineralization and collecting stream sediment samples (n = 67) for heavy mineral fractions in a sampling density of 1 per 10 m2. The samples were analyzed for their geochemical and mineralogical compositions using instruments such as inductively coupled plasma-mass spectrometry (ICP-MS), atomic absorption spectrometry (AAS), and energy dispersive X-ray fluorescence (EDXRF). The obtained results were subjected to Sequential Binary Partition, followed by appropriate mathematical log-ratio transformations to deal with inherent problems associated with compositional data. The obtained data was then analyzed using descriptive statistics, analysis of Median Absolute Deviation, and threshold mapping was employed to delineate geochemical anomalies. Univariate and multivariate analyses were employed to understand the geochemical associations, dispersion patterns, and geological processes. The result revealed that Mo, Cu, Zn, Au, Sr, Zr, Ce, W, Nb, Ta, and Be were anomalous in the stream sediment samples. The new anomalies of base and rare metals, precious metals, and gemstone likely mineralization were supported by evidence from mineralogical and mineral ore studies. The proving showed that mineralization of the Basement terrain is towards the West of Lokoja while the significant Fe anomalies suggest being from goethite, haematite, ± siderite-bearing ironstone formations generally found in the northern part of the study area.

Abstract

Motor function defect caused by central or peripheral nerve injuries has become a global burden. Peripheral nerve transfer is an effective surgical method in restoring motor functions of upper limb after nerve injuries in general. However, the outcome of individual function recovery is less predictable. It is crucial to access the real-time monitoring of function improvement in the peripheral nerve level. Here, we developed a fully implantable multisite optogenetic stimulation system(FIMOSS), which is tailored for wireless, reprogrammable and long-term monitoring of peripheral nerve plexus functions. In Thy1-ChR2-EYFP mice, our system elicited diverse forelimb movements when illuminating each nerve bundle from different angles, confirming its spatial selectivity for the monitoring of precise brachial plexus functions. Furthermore, we applied FIMOSS on a nerve transfer mice model after traumatic brain injury and discovered innervation pattern of the transferred nerve to multiple forelimb muscles along with the functional compensation of adjacent nerve trunks in brachial plexus consecutively within 12 weeks after surgery, during which FIMOSS has demonstrated stable operation. Our technology enabled refined evaluation of electrophysiological and motor functions of peripheral nerve plexus, shining light upon personalized diagnosis and treatment after central or peripheral nervous system injuries or nerve surgeries.

Published: January 2025

Abstract

Long-term PM2.5 exposure is a risk factor for cardiovascular mortality. Fossil fuel burning is a large source of PM2.5. Here, a global health impact assessment was conducted utilizing 7 future scenarios evaluating strategies to reduce PM2.5 exposure, including reducing fossil fuel use, air pollution control, adopting cleaner cooking methods and combinations thereof. Under current trends, air quality is projected to improve by 2050, but the absolute attributable burden of ischemic heart disease remains high in many regions. Promoting cleaner cooking is effective in the short term (by 2030) in South and Central America, Asia, and Africa in reducing the health burden. In the long term (by 2050), for most regions, only strategies that simultaneously target ambient and cooking related PM2.5 resulted in sustained improvements for reducing ischemic heart disease burden. For, North Africa and the Middle East region the population attributable fraction remains high across all scenarios. PM2.5 exposure remains above the WHO Air Quality Guidelines across all scenarios therefore additional strategies are required to improve air quality.

Published: January 2025

Abstract

Background: Latin America faces multiple barriers to healthcare access, particularly affecting the pediatric population. Factors such as socioeconomic vulnerability, armed conflicts, disasters, and insufficient healthcare spending contribute to these difficulties. The barriers include financial, bureaucratic, and geographical issues, negatively impacting the well-being and development of children.
Objective: To identify the barriers to healthcare access in the vulnerable pediatric population of Latin America and recognize effective strategies to overcome them.
Methods: An scoping review was conducted in December 2024. A literature search was performed in databases such as BIREME, PubMed, and Scopus, including studies published between 2014 and 2024 in English and Spanish. Specific inclusion and exclusion criteria were applied, and the RAYYAN tool was used to manage the references.
Results: Twenty-eight articles met the selection criteria. Of these, 28.57% discussed sociodemographic barriers, highlighting geographical issues and gaps in government support; other articles addressed vaccination, mainly social stigmas and lack of supplies; and 17.8% focused on specific diseases, highlighting the lack of early access and complications. Additionally, 17.8% discussed strategies such as telemedicine to improve healthcare access in remote areas.
Conclusion: The barriers to healthcare access in the pediatric population of Latin America are diverse and complex. Telemedicine emerges as a promising strategy, ensuring access, follow-up, and medical consultation, reducing secondary complications due to late or non-existent care for remote communities. Additional studies with robust methodologies are required to improve the applicability of the recommendations.

Abstract

A 36-year-old female was evaluated for pelvic pain of 6 months duration. She presented to our clinic with the MRI report suggestive of a well-defined, solid, T1 heterogeneously hypointense and T2 heterogeneously hyperintense lesion displaying post-contrast enhancement, central non-enhancing cystic areas, and areas displaying diffusion restriction, measuring 5.1 x 5.0 x 5.7 cm (APXTRXCC), noted in the mid pelvis at the level of the L5 vertebral body and the L5-S1 intervertebral disc. (Fig 1.). Black arrow pointing to the tumor. The lesion was noted closely abutting the bilateral iliac vessels posterolaterally. Anteriorly the lesion was noted abutting small bowel loops. Functional paraganglioma was ruled out by testing plasma-free metanephrines and 24-hour urine vanillylmandelic acid levels. CT scans of the head, neck, chest, and abdomen were performed to exclude the possibility of neural crest tumors in other sites. She underwent laparoscopic transperitoneal soft tissue tumor excision.When abdominal paragangliomas are possibly resectable, surgical excision is the preferred course of treatment; typically, this is done through an open procedure. The laparoscopic approach has been reported to be difficult for retroperitoneal paragangliomas due to the difficulty of handling a large tumor with forceps, extreme vascularization, and demanding localization despite the recent trend towards minimally invasive surgery.7

Authors: 陈奕睿  
Published: January 2025

Abstract

Background: The rapid growth of the healthcare industry in China has led to a significant talent gap, particularly in the areas of digital skills and management expertise. This study aims to bridge this gap by analyzing healthcare job listings using natural language processing (NLP) techniques to identify specific skills and management capabilities in high demand.
Methods: We collected 42,032 healthcare job listings from eight major recruitment websites in China, focusing on positions requiring a bachelor’s degree or higher and posted within the last year. To extract relevant information from job descriptions, including required skills, qualifications, and roles, we employed an AI agent based on the latest ChatGPT model. The model was fine-tuned using advanced Prompt-Tuning techniques to adapt it to the specific context of healthcare job listings. This involved designing task-specific prompts, preprocessing the data to remove duplicates and normalize text, and training the model using the Hugging Face Transformers library.
Results: The analysis revealed a strong demand for technical skills such as data analysis (mentioned in 53.65% of listings), AI and machine learning (18.05%), and technology integration (28.3%). Compliance and data privacy skills were also highly demanded, reflecting the healthcare sector’s commitment to regulatory adherence and data security. Additionally, management and leadership skills were identified as critical, with project management mentioned in 46.32% of listings. Regional disparities were observed, with higher demand for digital skills in urban areas such as Beijing and Shanghai compared to rural regions. Emerging roles such as “digital health strategist” and “chief data officer” were also identified, highlighting the need for interdisciplinary collaboration and innovation.
Conclusions: This study provides valuable insights into the current and future talent demands in the healthcare industry. By leveraging NLP techniques to analyze job listings, we can identify specific skill gaps and develop targeted strategies for talent development and recruitment. This research contributes to the understanding of the healthcare talent gap and offers practical recommendations for policymakers, healthcare providers, and educational institutions to ensure a sustainable and skilled workforce in the healthcare sector. Future research should explore additional data sources and qualitative methods to gain a more comprehensive understanding of healthcare talent needs globally.
