Authors: Bailly Claude , Doat Jacqueline
Published: January 2025

L'utilisation de sources d'énergie fossiles telles que la tourbe et le bois fossiles permettrait au Sénégal de réduire l'exploitation des formations ligneuses naturelles. Des gisements existent dans les Niayes où la tourbe seule représente environ 16 millions de tonnes dont 11 millions sont facilement exploitables.Pour être utilisée comme combustible, la tourbe doit être séchée et moulée avant d'être carbonisée. Pour ce faire, on peut utiliser les techniques de la meule casamançaise, de la cornue métallique ou du four métallique, mais c'est la méthode de la pyrolyse qui donne les meilleurs résultats.Le bois fossile peut également être carbonisé.Pour la tourbe, une unité pilote de 5 fours devrait être développée au Sénégal.L'utilisation du bois fossile dépend des quantités disponibles.

Published: January 2025

Resumen:
Los años finales de la dictadura franquista fueron momentos de una importante movilización antifranquista, desde diferentes territorios y espectros sociales. Como contrapartida, la represión también fue en aumento. En dicha violencia estatal, la Brigada Político Social (BPS), jugó un papel relevante, ya que era la policía encargada de los delitos políticos y uno de los pilares del régimen para hacer frente a la “subversión”. La idea de este artículo es analizar la actuación de los agentes de este Cuerpo contra las diferentes militancias contra la dictadura, sus orígenes y sus cambios a la largo de la dictadura. También ver como la oposición se enfrentó en los años del tardofranquismo a esta represión, si le hizo frente o no y con qué intensidad.

Li-rich Mn-based cathode materials (LRM) have received great attention owing to their high capacity and low cost. However, the mismatch between the widely used carbonate electrolyte and the LRM cathode and lithium metal anode causes a series of problems, such as electrolyte continuous oxidation, cathode structure degradation, and Li dendritic growth. Herein, inorganic oxide B2O3 is introduced as a dual-functional high-voltage electrolyte additive to construct stable cathode electrolyte interphase and solid electrolyte interphase for Li||LRM batteries. The modified interface derived from the additive can induce dendrite-free Li deposition, stabilize cathode structure, and inhibit transition metal dissolution. Moreover, the adverse side reactions are mitigated, thus enhancing Li+ transport rate and reducing interface impedance. With the addition of B2O3 into the carbonate electrolyte, the Li||LRM battery exhibits an enhanced discharge capacity of 221 mAh g-1 after 200 cycles, equaling a capacity retention of 92.1%. When the upper cut-off voltage is increased to 5 V, a superior capacity retention of > 85% can still be achieved after 150 cycles at 1 C. In addition, the low cost of B2O3 benefits for commercial application. This work offers new guidance for the research of low-cost, high-voltage dual-functional additives for advanced lithium metal batteries.

Efficient Contact Algorithm for 3D Finite Element Modeling of Bottomhole Assemblies: Validation and Application
Authors: Zhang He , Tian Kaixiao , Bhaidasna Ketan
Published: January 2025

Static analysis of the lateral deformation of a bottomhole assembly (BHA) is essential for controlling borehole trajectories in directional drilling. A major technical challenge in static BHA modeling is efficiently determining the contact configuration between the BHA and the borehole wall. This configuration, including contact locations and orientations, is not known a priori and introduces nonlinearities into the analysis. Most algorithms addressing the contact problem in BHA modeling are proprietary and lack detailed descriptions. Explicit algorithms based on the Newton-Raphson iteration method and linear/nonlinear complementarity problem formulations have limitations, such as computational inefficiency and the need for predefined contact locations. In this paper, we derive governing differential equations for 3D BHA static deformation, incorporating nonlinear effects from borehole curvature, axial forces, and both discrete and continuous contacts. The finite element method (FEM) is used to solve these equations under appropriate boundary conditions. Within the finite element framework, the Lagrange multiplier method (LMM) is used to impose displacement constraints at contact points, while an innovative iterative process ensures the unilateral nature of the contacts. The algorithm typically converges in O(10) iterations, with each iteration involving the solution of approximately O(102) finite element equations, ensuring high computational efficiency. The algorithm, grounded in principles of structural mechanics, is robust across a wide range of conditions, and its accuracy is validated against a published algorithm. The proposed BHA model is further validated using downhole measurements. In one scenario, bending moment on bit (BOB) measurements from a BHA equipped with a rotary steerable system (RSS) shows strong agreement with the model results, both in magnitude and variation pattern, when a fixed displacement boundary condition is applied at the bit. In another scenario, the BHA model is integrated with a bit-rock interface law to predict borehole propagation trajectories, demonstrating alignment with survey data when the bit side-cutting efficiency is fine-tuned. Additional analyses, including an evaluation of whirling-induced downhole tool failure, are provided in the supplementary material. These validations underscore the versatility and accuracy of the proposed model across various stages of the drilling process. Its computational efficiency makes it suitable for both offline and real-time applications, including prejob BHA designs and the development of operational parameter roadmaps for borehole trajectory control and vibration suppression, real-time integration with downhole measurements to optimize drilling performance, and post-job analysis to diagnose the root causes of undesirable drilling dysfunctions.

Authors: Zhang Yanling , Long Kun , Zhang Yun , Li Zhijian , Dai Ruping , Zhang Shuiting
Published: January 2025

Background
Despite surgery is the recommended treatment for oral cancer patients, little is known about intraoperative blood loss in this population. This study sought to identify risk factors for intraoperative haemorrhage in oral cancer resection and free flap reconstruction surgery, and to develop a machine learning-based predictive model.
Methods
This retrospective cohort study included patients with oral cancer who underwent resection and fibular flap reconstruction at a tertiary hospital. Demographic and clinical parameters were selected using a Recursive Feature Elimination algorithm. The final model for further analysis was selected after considering precision, accuracy, and area under the curve.
Results
A total of 452 individuals who had surgery for oral cancer met the criteria, with 179 individuals (39.6%) experiencing intraoperative hemorrhage, which results in higher inpatient expenses and longer durations of stay. Subsequently, 11 of 47 variables were picked for machine learning model building. In comparison, Random Forest had the highest area under the curve (AUC) (0.835, 95% CI 0.773–0.898), precision, and accuracy. Further feature importance evaluation and Shapley additive explanation analysis revealed that hemoglobin, surgical duration, total bilirubin, leucocyte count, tumor size, albumin, and Charlson comorbidity index score were significant risk factors for intraoperative bleeding. A nomogram algorithm utilizing the factors listed above was used to interpret and predict the possibility of operative hemorrhage Individualized for patients undergoing oral cancer resection and free flap reconstructive surgery.
Conclusions
Hemoglobin, surgical duration, total bilirubin, leucocyte count, tumor size, albumin, and Charlson comorbidity index score proved to be significant predictors of intraoperative hemorrhage, and Random Forest can be applied to predict the possibility of bleed loss in oral cancer resection and free flap reconstruction surgery. This study helped provide a more adequate preoperative evaluation, blood preparation for patients, and optimal blood resource utilization.
Hysteresis and Thermomagnetic Characteristics of Soils and Rocks in Eastern Botswana
Authors: MOIDAKI Moikwathai. , RANGANAI Rubeni. T. , KING James. G.
Published: January 2025

Soil magnetic properties are important for many applications including palaeomagnetism and (plate) tectonics, geological interpretation, geoexploration, mining, forensics, geotechnical engineering, and industry. The results of this work are a continuation of previous work on magnetic susceptibilities of soils in eastern Botswana. The magnetic properties measured include Curie temperature (Tc) determined in nitrogen gas atmosphere and hysteresis parameters (Hc, Hcr, Mr, Ms). Thermomagnetic curves were measured from room temperature up to 700 oC, enabling determination of Curie temperature which has supported the classification of the magnetic granulometry and mineralogy.
The thermomagnetic curves revealed the existence of magnetic minerals such as hematite, magnetite and pyrrhotite, and their Curie temperatures were found to be 600 °C, 580 °C, and 200 °C, respectively. The presence of magnetic materials is also revealed by the hysteresis loops of some soil samples. The hysteresis and thermomagnetic curves both indicate that the main contribution comes from magnetite-like phases. Thermomagnetic curves of soil samples collected along the Ramatlabama to Ramokgwebana, which traverses through the Kaapvaal Craton, Limpopo belt and Zimbabwe Craton could be used to differentiate the boundaries of the cratons and the orogenic belt. Airborne magnetic data covering the study area are being interpreted with particular reference to some of the measured magnetic properties and determined soil characteristics thereby increasing confidence in the geological interpretation.

Authors: Bernués-Caudillo Leticia , Drury Amanda , Gonzalez-María Esther , Moreno-Casbas Mª Teresa
Published: January 2025

Background
The selection, application and reporting of theories, models, and frameworks in implementation science can be challenging, hindering study comparisons and the advancement of science. Context analysis is a critical but underdeveloped area in implementation research. Structured approaches, such as coding frames informed by implementation science, can enhance methodological rigor and transparency. This study, part of the Sumamos Excelencia project, addresses these challenges by applying implementation frameworks to assess implementation context developing a coding frame to analyze qualitative interviews conducted during the project. The project implemented evidence-based recommendations in Spanish healthcare units using a multifaceted implementation strategy.
Methods
A literature review guided theories, models, and frameworks selection, integrating the Consolidated Framework for Implementation Research, Tailored Implementation for Chronic Diseases checklist, Expert Recommendations for Implementing Change, and Exploration, Preparation, Implementation, Sustainment framework. A coding frame was developed adhering to the content-driven process phases of Schreier’s methodology (selecting, structuring and generating, revising and expanding) and considering its requirements for a coding frame (unidimensionality, mutual exclusiveness, exhaustiveness, and saturation).
Results
Each framework provided valuable insights into the coding frame, complementing each other and enabling a comprehensive analysis of the complexity and multi-level aspects of context and implementation process. The integration of the results of the data-driven and concept-driven strategies resulted in a coding frame composed of 4 levels, 11 sublevels, 16 categories, and 82 contextual factors. The levels include factors related to the individuals involved in the implementation, factors related to the characteristics of the unit (internal context), factors related to the external context of the unit and factors related to the project's global implementation strategy. The strategies and the temporal phases were also incorporated into the coding frame.
Conclusion
This coding frame systematically captures context complexity, integrating constructs from multiple theories, models, and frameworks. It supports rigorous, standardized context analysis that is applicable beyond this project. This framework also offers a practical tool for mixed-method implementation studies, enabling novice researchers and healthcare professionals to analyze context comprehensively. Future research should validate and refine this framework across diverse settings to enhance its utility in advancing implementation science.

Published: January 2025

Anaerobic ammonium oxidation (anammox) is currently recognized as the most cost-effective process for wastewater nitrogen removal. In this study, the effects of volcanic rock, polyurethane sponge, fiber balls, and nylon fibers as stationary carriers, as well as the composite packing consisting of polyurethane sponge and nylon fibers, were evaluated in lab-scale fixed-bed biofilm reactors. The overall performance of the fixed-bed reactors with four types of carriers from priority to inferiority was noticed as, polyurethane sponge, nylon fibers, volcanic rock and fiber balls, with the composite packing using polyurethane sponge and nylon fibers performing better overall than the single packing under the same packing ratio of 50 v%. The porous structure of the polyurethane sponge facilitated the attachment of anammox bacteria, which contributed to achieving a total nitrogen removal rate of 0.945 kg-N/(m3-d) in 52 days. The composite packing of polyurethane sponge and nylon fiber combines the advantages of the two types of packing, and is able to achieve an average [[EQUATION]] removal efficiency of 85.6% at HRT of 6 h. The dominant genus of anammox bacteria attached to polyurethane sponge was Candidatus_Kuenenia (24.3%), and the dominant genus of anammox bacteria attached to nylon fibers was Candidatus_Kuenenia (24.1%). In conclusion, the results provide strong evidence for the realization of efficient anammox process in a fixed-bed reactor with the composite packing using polyurethane sponge and nylon fibers, and would benefit towards accomplishing a stable partial nitritation-anammox process in the future.

Tri-Ponderal Mass Index (TMI) was used to assess adiposity levels. PSE (e.g., tobacco, alcohol, caffeine, and marijuana) was collected via maternal self-report. Latent growth mixture modeling was conducted to identify TMI trajectories, followed by multinomial logistic regression to examine the role of PSE in TMI profiles, controlling for various factors.
Results
Three trajectories were identified: Stable TMI (86.6%), Increasing TMI (12.5%), and Decreasing TMI (0.9%). The risk of exhibiting an Increasing TMI was associated with prenatal exposure to tobacco (β = 1.53, 95% CI = 1.26–1.86, p < .001) and caffeine (daily use: β = 1.39, 95% CI = 1.16–1.68, p < .001; weekly use: β = 1.38, 95% CI = 1.13–1.69, p < .05), with dose-dependent effects. Notably, tobacco exposure both before (β = 1.55, 95% CI = 1.27–1.89, p < .001) and after awareness of pregnancy (β = 1.51, 95% CI = 1.10–2.08, p < .05) contributed to this risk, with no significant benefit from maternal cessation after pregnancy awareness. Multiple PSE substantially elevated the risk of increasing adiposity (β = 1.70, 95% CI = 1.27–2.27, p < .001).
Conclusions
Obesity risk can emerge long before adolescence, even during prenatal development. The findings regarding the long-term influence of prenatal substance exposure on adiposity development during adolescence highlight the importance of preconception and prenatal health interventions to mitigate the risk of obesity in offspring.

Internet infrastructure construction is an important condition to promote the development of digital productivity, and an important guarantee to promote the digital economy as a new driving force for economic growth. This paper analyzes the impact of internet infrastructure development on digital productivity using 2011–2019 prefecture-level city panel data and a quasi-natural experiment on the "Broadband China" pilot policy. The study concludes that internet infrastructure development significantly promotes the development of digital productivity, and the result passes several robustness tests. The promotion effect of internet infrastructure construction on digital productivity has significant heterogeneity among regions, between cities of different administrative levels, and between cities in urban agglomerations and non-urban agglomerations. Meanwhile, the mechanism analysis finds that internet infrastructure development affects digital productivity development through four ways: attracting the concentration of highly skilled personnel, improving the level of marketization, stimulating the city's innovation vitality, and growing the science and technology service industry.

Lmphocyte to C-reactive protein ratio (LCR) has tremendous predictive power for diseases with similar pathogenesis to Kawasaki disease (KD). The evidence on the prognostic value of LCR for IVIG resistance, especially for repeated IVIG resistance in KD, was scarce. We conducted a prospective cohort study comprising 1607 individuals with Kawasaki disease to evaluate the predictive value of LCR for both the initial and repeated IVIG resistance in KD. A comparison was made between the initial/repeated IVIG-resistance group and the initial/repeated IVIG-response group. We found that LCR was markedly reduced in both initial and repeated IVIG non-responders and was recognized as an independent risk factor for forecasting both initial and repeated IVIG resistance in KD. The optimal cut-off values of LCR for predicting initial and repeated IVIG resistance were 0.042×10^9 and 0.025×10^9, respectively, with sensitivities of 74.1% and 51.3%, and specificities of 65.9% and 55.8%. LCR may be a complementary laboratory marker for predicting initial and repeated IVIG resistance to guide clinical management.
Effectiveness of Dry Needling for Chronic Low Back Pain: An Up-to-Date Meta-Analysis of Randomized Controlled Trials
Authors: Sario Alessandro Di
Published: January 2025

This meta-analysis evaluated the effectiveness of dry needling (DN) for chronic low back pain (CLBP) by synthesizing data from 13 randomized controlled trials (RCTs) involving 590 participants. Primary outcomes included pain intensity (Visual Analog Scale [VAS] or Numeric Pain Rating Scale [NPRS]), functional disability (Oswestry Disability Index [ODI] or Roland-Morris Disability Questionnaire [RMDQ]), and pressure pain threshold (PPT). Secondary outcomes assessed quality of life, flexibility, mobility, and psychological factors. A systematic search and random-effects model analysis found that DN significantly reduced pain intensity (SMD = -0.78; 95% CI: -1.05 to -0.52) and improved functional disability (SMD = -0.64; 95% CI: -0.91 to -0.37). Moderate PPT improvements were noted (SMD = 0.48; 95% CI: 0.21 to 0.75). Moderate to high heterogeneity (I² = 55%-70%) suggested variability in DN protocols and study designs. Subgroup analyses indicated DN combined with physical therapy yielded better functional outcomes than DN alone. While DN shows promise for short-term relief of CLBP, standardized protocols and long-term efficacy studies are needed. PERSPECTIVE This meta-analysis highlights dry needling's potential for reducing pain and improving function in CLBP management, supporting its integration into multimodal treatment strategies.
Conceivability, existence, and logic
Authors:   , Kauß Dominik
Published: January 2025

One of the central themes of this essay is the contrast between two notions of conceivability, which, as a first approximation, may be circumscribed in terms of the distinction between what is rationally imaginable (imaginative conceivability), as opposed to what is rationally believable (doxastic conceivability, i.e. the dual of indubitability). In recent years, the philosophy of conceivability has been dominated by the question whether conceivability, in some suitable sense, entails possibility. This essay shifts focus toward the question whether imaginative conceivability entails doxastic conceivability; and in the last two chapters addresses the question whether possibility entails conceivability, in either of the two above senses. Much of the discussion will focus on the characteristic truths of classical first-order logic with identity, and in particular on singular existential sentences, i.e. sentences stating the existence of some respective individual. Once suitably regimented, sentences of this kind figure as theorems in classical first-order logic. According to the received view, this circumstance is a mere artifact resulting from simplifying stipulations in the formal semantics of first-order logic, and should not be taken as an indication that singular existential sentences are logically true in any substantial respect. Although this caveat is legitimate as far as it goes, it will be suggested that in one important but unduly neglected sense of logical truth, true singular existential sentences are not just true, but indeed logically true. In particular, it will be argued that the proposition expressed by the negation of a singular existential sentence fails to be doxastically conceivable.
The claim is discussed in semantic, pragmatic, epistemological and logical respect and defended against foreseeable objections extracted from a variety of philosophical views ranging from skepticism to disquotationalism, temporalism, descriptivism, the causal theory of reference, as well as coarse- and fine-grained conceptions of propositional content. Also discussed are the claim’s ramifications for traditional notions of analyticity and apriority. Two equally legitimate notions of analyticity will be distinguished, one strictly stronger than the other, and true singular existential sentences will be found to be weakly if not strongly analytic. As regards apriority, it is argued that if true singular existentials are not a priori, then, since they are indubitable, some propositions are indubitable even if not a priori. Conversely, if all indubitable propositions are a priori, then, since true singular existentials are indubitable, they are a priori, and presumably many of them will have to be countenanced as novel examples of the Kripkean category of the contingent a priori. Either consequence would be of significance, the former to epistemology in general, the latter to the epistemology of existence in particular.

A automedicação, prática amplamente disseminada, tem sido uma das principais causas de intoxicação e efeitos adversos à saúde, especialmente quando realizada de forma inadequada. Embora a automedicação responsável possa trazer benefícios, como a redução de sintomas e custos com saúde, sua prática indiscriminada constitui um grande desafio para a saúde pública. Este estudo teve como objetivo investigar os comportamentos relacionados à automedicação infantil na cidade de Aracati, Ceará. Foi realizado um estudo descritivo, quantitativo e prospectivo com aplicação de questionário a pais ou responsáveis de crianças com idade de 0 a 14 anos, que buscaram medicamentos sem prescrição médica em farmácias comunitárias. A amostra foi composta por 95 participantes, e os dados foram analisados por meio do programa IBM SPSS Statistics®. Os resultados mostraram que a prática de compartilhamento de medicamentos e a guarda de sobras de medicamentos foram comuns entre os responsáveis. Além disso, a maioria dos participantes indicou o uso de antitérmicos e analgésicos sem prescrição médica, sendo os balconistas de farmácia a principal fonte de recomendação. O principal motivo para a automedicação foi o elevado custo das consultas médicas. A pesquisa conclui que, apesar de alguns benefícios, a automedicação, quando realizada de forma inadequada, pode trazer sérios prejuízos à saúde infantil, sendo necessário promover a educação em saúde para conscientizar a população sobre os riscos dessa prática.
