LA VIOLACIÓN DE DERECHOS HUMANOS EN MÉXICO: UN REFLEJO DE LA ORFANDAD INSTITUCIONAL
Authors: Vázquez Angélica Cuéllar , Martínez Analy Loera
Published: February 2025

Resumen: Este artículo tiene por objetivo mencionar la relación que existe entre la violación a los derechos humanos en México, la desigualdad social, la corrupción, la impunidad y la falta de acceso a la justicia. Para lograr el objetivo se recurrió al concepto de orfandad institucional como resultado del desamparo de las autoridades hacia las víctimas de violación a los derechos humanos. Por décadas México se ha caracterizado como un país donde los contextos de corrupción e impunidad permiten generar escenarios de desigualdad social, poco o nulo acceso a la justicia y, por consecuencia, una sistemática violación a los derechos de los ciudadanos, provocando agravio social, desconfianza e incertidumbre en las prácticas de los agentes del Estado. Al final se describieron posibles retos y obstáculos para erosionar la orfandad institucional y, con ella, la consolidación de un Estado social y Democrático de Derecho en el país.

This study aimed to analyze scientometric profile of publications on neglected tropical diseases (NTDs) in Haiti, 1923-2022. We conducted a scientometric study based on indexed scientific productions related to NTDs in Haiti. The search syntax in the Scopus database was based on key terms for NTDs recognized by the World Health Organization in 2022, focusing on keywords, titles, and abstracts. VOSviewer 1.6.18 was used to create bibliographic networks according to authorship, country of origin, institution, and descriptors. A total of 281 publications were identified, 87.9% (247/281) original articles, with an increase of 45.1% (127/281, annual average of 12.7 publications) in the last decade (2013-2022) compared to the first half of the analyzed period (1923-1975, annual average of 0.21 publications). The authors with the highest number of publications were: Lammie PJ (n = 51), Eberhard ML (n = 29), and Wallace RM (n = 25). A total of 83 institutions participated in the research and the Centers for Disease Control and Prevention (United States) had the highest proportion of affiliations in the coauthorship versus organizations analysis (n = 86), with authors from 35 countries. Coauthorship by country shows publications between institutions in the Americas (n = 13), Europe (n = 9), and Asia (n = 5). The analysis of cooccurrence versus author keywords shows higher occurrence of the terms “dengue” and “rabies”. There is a very limited number of publications on NTDs in Haiti throughout a century of publications, despite the relative increase in recent decades. Such publications are concentrated among foreign authors, with limited national coauthorship.

Published: February 2025

Resumo: Este artigo analisa as percepções de manifestantes que participaram dos protestos de junho de 2013. Através de entrevistas em profundidade, realizadas nos meses seguintes às manifestações, buscamos analisar as narrativas dos ativistas sobre os rituais de participação, suas percepções sobre a natureza e motivações dos protestos e o modo pelo qual foram atraídos ou convocados a participar das mobilizações. Apesar da diversidade de perfis e da grande quantidade de pautas emergentes durante os protestos, identificamos duas formas principais de constituição e participação dos sujeitos políticos, a partir da distinção entre indivíduos com e sem experiência política ou associativa prévia. Neste artigo, observamos como essas diferenças influenciaram as formas de participação e os diversos enquadramentos dos manifestantes em relação aos partidos e à representação política.

ABSTRACT: Platelet-Rich Plasma (PRP) directly and indirectly modifies the composition of synovial fluid in horses. This study evaluated the early effects of intra-articular PRP on the synovial fluid of horses with experimentally induced synovitis. Twelve horses were divided into two groups: a control group that received no treatment, and a treatment group that received intra-articular PRP. Five time points were established: T0, T3, T6, T24, and T48. At T0, all horses received an intra-articular injection of lipopolysaccharide from Escherichia coli. At T3, synovial fluid samples were collected from all horses, and the treatment group received PRP via the same joint access. Additional synovial fluid samples were collected at T6, T24, and T48 for evaluation. The PRP preparation protocol used in this study resulted in an adequate platelet concentration that did not affect the physicochemical and cytological characteristics of the synovial fluidor the concentrations of IL-1RA, MMP-9, and MMP-2 in horses with induced synovitis.

ABSTRACT: A2 milk contains the A2 β-casein protein, which does not release the opioid peptide β-casomorphin-7 (BCM-7) during digestion. However, there is limited knowledge among Brazilian consumers regarding the concept, characteristics, benefits, and market niche of A2 milk. This study assessed the perceptions of the Brazilian population about A2 milk and its derivatives. A total of 462 individuals from various age groups, educational backgrounds, and states of residence participated in the survey. Only 15.4% (71) had consumed A2 milk, while 58.4% (270) were unaware of the differences between A1 and A2 milk. Additionally, 69% (319) could not explain the basis for classifying different types of milk, and only 31% (143) correctly identified the benefits of A2 milk compared to regular milk. Furthermore, 15.8% (73) reported lactose intolerance, and 5% (23) had a milk protein allergy, conditions often confused with the effects of BCM-7. The results suggested that few Brazilian consumers are aware of the genetic polymorphisms in milk, underscoring the need for better consumer education, particularly concerning the benefits for individuals with milk intolerances or allergies
Development of ductile iron alloy for ADI production using heated air in austempering
Authors: Pereira Leonardo , Pasini Willian Martins , Barcellos Vinicius Karlinski de
Published: February 2025

Abstract Ductile iron is typically used in as-cast conditions. However, a typical heat treatment applied to ductile iron is austempering, which allows for increased tensile strength with good levels of elongation and toughness. The traditional means of austempering involves molten salt baths, but these baths have environmental and operational restrictions. Laboratory-level studies have found the feasibility of using heated air for cooling and holding during austempering. Due to the lower cooling severity of heated air, it is necessary to increase the austemperability of ductile iron. Elements that contribute to austemperability are manganese, copper, molybdenum, and nickel. This study used numerical, thermodynamics, and kinetics simulation to develop a suitable ductile iron alloy for obtaining ADI in a standard ASTM test specimen using heated air for cooling. According to the numerical simulation results, the average cooling rate between 900°C and 500°C in the critical region for air velocities of 5 m/s and 10 m/s at a temperature of 280°C ranged from 75°C/min to 82°C/min. Through thermodynamic and kinetic simulation, nickel has the most significant capacity to alter the austemperability of ductile iron. Based on these results, six ductile iron alloys with nickel contents ranging from 0.2 to 2% were developed. The experimental cooling rate is approximately 70°C/min, with the 3.41C, 2.72Si, 1.01Cu, 0.31Mn, 0.18Mo, and 1.13Ni alloy suitable for obtaining ADI.

Published: February 2025

Abstract This study aims to enhance the mechanical properties of the hypoeutectic Zn-Al-Cu alloys, known for their low melting point and good machinability but limited by low tensile strength and brittle fracture behavior. The present research investigates the effect of TiB2 additions in concentrations of 0.2, 0.5, 0.8, and 1.1 wt.% on a Zn-Al4-Cu1 alloy to improve these properties. The alloys were produced by gravity casting into a cast iron mold, and their mechanical properties were analyzed. Additionally, the effects of the cooling rate on the microstructure and secondary dendritic spacing (λ2) were analyzed using a stepped mold with different cooling modules. The additions of TiB2 modified the morphology of the primary η-Zn phase and the eutectic constituents (α+η). The optimal mechanical properties were obtained in the Zn-Al4-Cu1 alloy with 0.8% TiB2. Furthermore, increased cooling rates reduced the λ2 in the primary η-Zn phase from 21.4 μm to 11.3 μm. These findings show a manner to enhance the overall properties of Hypoeutectic Zn-Al alloys.

Published: February 2025

Abstract In the northern region of Brazil, enormous amethyst quartz waste is generated in mining, currently with no final destination, being stored without commercial value. However, it can be used to produce artificial aggregates, aiming to provide a solution to the storage problem of this material. To reduce the waste, crushing and grinding were used, investigating the factors influencing comminution, such as mineralogical properties and size settings, filling, speed and grinding time. Fragmentation was carried out on a laboratory-scale using a jaw crusher and ball mill. The factors in crushing depend on the gap and set, constants, while in grinding, with constant critical speed, the filling factor, the balls:sample ratio and grinding times were considered variables. The fineness modulus for fine aggregates was used. Based on the particle size distribution of crushing and grinding products, the production of coarse particles in crushing is the highest (75%), being considered as coarse aggregates, while the production of fine particles in grinding is lower (25%) and is considered as fine aggregates. The banded quartzite influences the comminution, more favorable to produce a coarse aggregate. The distribution of particle size shows that within the coarse aggregates, 40% corresponds to G1 gravel. Crushing is determined by the size settings and grinding by the grinding time. For longer grinding times, there is a greater reduction in grain sizes, and for shorter times, the reduction is smaller. The waste could be fed into comminution to produce coarse and fine aggregates for civil construction, achieving a long-term sustainable supply of aggregates in the required quantities.

Published: February 2025

Abstract Recycling LFP-type lithium-ion batteries is essential for recovering valuable metals such as lithium. The efficient extraction of this material contributes not only to the conservation of limited natural resources, but also to reducing dependence on mining. In addition, proper recycling minimizes the risks of releasing toxic substances into the environment, promoting more sustainable practices in the automotive industry. Exploring advanced recycling technologies is crucial to optimizing the process and increasing efficiency in material recovery. Methods such as pyrometallurgy and hydrometallurgy have the potential to obtain high yields in the recovery of precious metals, contributing to the economic viability of recycling automotive batteries. In this study, the effect of a hydrometallurgical process on the recovery of lithium salts from spent LiFePO4 batteries was studied, using an aqueous solution of nitric acid as the medium. Around 99.23% of Fe and 84.18% of Li were recovered as FeOH and Li3PO4. According to the proposed mechanism, the LiFePO4 cathode powder was more easily destroyed and transformed into disordered states at concentrations with a 10% stoichiometric excess, leading to a significant increase in leaching and efficiency in lithium concentration.

BACKGROUND: The mortality rates of prostate and testicular cancer are higher mortality in the northeast region. OBJECTIVE: We aimed to compare the efficacy of machine learning libraries in predicting testicular and prostate cancer mortality. DESIGN AND SETTING: A comparative analysis of the pyMannKendall and Prophet machine-learning algorithms was conducted to develop predictive models using data from DATASUS (TabNet) to Caicó (Brazil) and Rio Grande do Norte (Brazil). METHODS: Data on prostate and testicular cancer mortality in men from 2000 to 2019 were collected. The prediction accuracy of the Prophet algorithm was evaluated using the mean squared error (MSE), the root mean squared error and analyzed using the pyMannKendall, and Prophet libraries. RESULTS: The research data were made publicly available on GitHub. The machine test confirmed the accuracy of the predictions, with the root MSE (RMSE) values closely matching the observed data for Caicó (RMSE = 2.46) and Rio Grande do Norte (RMSE = 22.85). The Prophet algorithm predicted an increase in prostate cancer mortality by 2030 in Caicó and Rio Grande do Norte. This prediction was corroborated by the pyMannKendall analysis, which indicated a 99% probability of a rising mortality trend in Caicó (P < 0.01; tau = 0.586; intercept = 2.59) and Rio Grande do Norte (P = 2.06; tau = 0.84, and intercept = 119.63). For testicular cancer, no significant mortality trend was identified by Prophet or pyMann-Kendall. CONCLUSIONS: Libraries are reliable tools for predicting mortality, providing support for strategic health planning, and implementing preventive measures to ensure men’s health. Addressing the gender gap in DATASUS is essential.

ABSTRACT A double-fed induction generator (DFIG) based wind energy conversion system (WECS) has been proven to be an efficient solution for electrical energy generation from wind. In this paper, the design process of cascade control loops for the implementation of a maximum power point tracking (MPPT) control algorithm on a DFIG-based WECS is presented. A tip speed ratio algorithm (TSR) was chosen in this work to generate reference turbine speed signals for harvesting maximum energy from all wind profiles. The design methodology of cascade controllers for the power electronics converter is explained in detail in this work and the performance of the system in extracting maximum power from wind is evaluated using Matlab/Simulink simulation tool. The simulation results are proved that the tuned controllers are able to operate the wind energy conversion system at maximum power point in extracting maximum energy from all types of wind profiles.

Abstract Climate change intensifies drought, which increases susceptibility to phytopathogens in several crops such as the Chinese potato (Colocasia esculenta). This species is cultivated in tropical areas mainly for the production of corms, which are affected by Fusarium oxysporum dry rot. Phytopathology treated with toxic chemicals, which highlights the biocontroller Trichoderma harzianum, which also helps reduce the effects related to drought in other crops. Therefore, the objective was to characterize the response of C. esculenta to drought and infection by F. oxysporum, and the effectiveness of treatment with T. harzianum. Greenhouse tests were carried out with three factors (F. oxysporum, T. harzianum and drought), each with two levels (presence and absence) (N=48). Plant growth was evaluated for 30 days, in addition to the relative chlorophyll content, maximum efficiency of photosystem II, water content (WC%), incidence and severity. It was obtained that abiotic and biotic stress decreases growth. Drought lowered photosynthetic efficiency, and both stressors reduced chlorophyll in plants not treated with T. harzianum. Stress decreased leaf and corm WC%, but this effect was reduced by the biocontroller. This fungus reduced the incidence of F. oxysporum, and the severity of foliar symptoms for both types of stress. In conclusion, abiotic and biotic stress differentially impacts C. esculenta, and T. harzianum tends to improve growth under stress. However, more studies are required to evaluate its benefit on productivity. This work is one of the first to describe the stress response of this crop, and highlights its importance for future technification plans.

Abstract Commercial yeast has been frequently employed to improve the digestibility of ruminant diets, albeit these microorganisms are not indigenous to the rumen microbiome. In this investigation, our aim was to assess the in vitro digestibility of Urochloa decumbens hay (UDH) with the incorporation of two selected yeast strains isolated of ruminal fluid of Zebu cattle. Rumen fluid was collected at the onset, midpoint, and final of the dry period in a semiarid region Brazil. UDH samples were obtained from the same region. Within simulated ruminal chambers, we included McDougall buffer solution, ruminal fluid, Ankon F-57 bags containing UDH samples. Sabouraud broth (control), V62 yeast (Pichia kudriavzevii), V5 yeast (Rhodotorula mucilaginosa), or a combination thereof (mixture) were evaluated as inoculant to the ruminal fluid. The incorporation of V5, the combination of both isolates, and V5 alone resulted in significantly elevated in vitro dry matter digestibility of UDH for ruminal fluid collected at the initial, intermediate, and final stages of the dry season, respectively. Moreover, the yeast isolates demonstrated resilience to the in vitro acid digestion process, indicating their potential utility in the formulation of probiotics or microbial supplements for ruminants raised in tropical pastures during dry season.

Abstract Rabbit meat is a source of protein and is beneficial to health. Bambu Apus rabbits are formed from crosses of several rabbit breeds and have adapted to the environment of DKI Jakarta. The development of rabbits is expected to support an integrated and sustainable urban livestock farming program (sustainable integrated urban farming). The samples used were 65 adult Bambu Apus rabbits and secondary data from 40 adult Rex rabbits and 40 adult New Zealand White rabbits. The observed variables included body weight and morphometrics such as head length, head width, head height, chest circumference, chest width, chest depth, radius ulna length, humerus length, tibia length, femur length, backbone length, hip width, ear length, and ear width. Variance analysis of each variable was carried out through SAS software version 9.4 using PROC GLM procedure, PROC DISCRIM was used for Mahalanobis distance analysis, PROC CANDISC was used for canonical analysis, and MEGA11 software for phenogram tree. The results of discriminant analysis showed that the Bambu Apus rabbit had different morphometric characteristics from the Rex and New Zealand White rabbit. The average weight of Bambu Apus rabbits was 2473.54±480.13 g higher (P<0.05) than Rex rabbit, chest depth 8.69±1.11 cm greater (P<0.05) than Rex and New Zealand White rabbit, backbone length 37.84±3.51 cm longer (P<0.05) than Rex rabbit. Genetic distance and phenogram tree construction showed low kinship relationship between Bambu Apus rabbit with Rex rabbits and New Zealand White rabbit. The results suggested that the genetic of Bambu Apus rabbit has a predisposed to be produced as tropical climate adapted broiler rabbits.

Abstract Enzootic Bovine Leukosis (EBL), is infectious disease affecting especially older animals, although animals of all ages can be infected with the Bovine Leukemia Virus (BLV). Crioula Lageana is a locally adapted, rustic and long-lived bovine breed, important as a genetic resource. However, little is known about its health status, making it difficult to preserve the breed. In this sense, this study aims to assess the prevalence of EBL/BLV in different animal categories of Crioula Lageana cattle. Then, blood samples were collected from 308 animals from different categories: bulls, cows, heifers and male and female calves, whereby these animals were derived from six farms located in nuclei of in situ conservation for the Crioula Lageana breed in Planalto Serrano de Santa Catarina, Brazil and the blood samples were analyzed with hemogram, ELISA and PCR tests. There was a prevalence of 6.82% (21/308) for the ELISA test and 36.69% (113/308) for the PCR technique. There was no association between categories and natural infection or BLV positivity in PCR by the Chi-square test (P<0.05). Leukocytosis with lymphocytosis was observed in 11% (18/113) of PCR-positive animals. None of the evaluated animals presented bovine lymphosarcoma. We conclude that the BLV is present in all animal categories of the Crioula Lageana cattle, requiring the establishment of prevention and control measures to avoid the spread of the disease within herds.
Operational capability as a mediator on the relationship between supply chain integration and operational performance
Authors: Domenek Antonio Carlos , Moori Roberto Giro
Published: February 2025

ABSTRACT Purpose: This article examines the role of operational capabilities as a mediator factor in the relationship between supply chain integration and operational performance. Originality/value: This is one of the first empirical studies to explore the relationship between elements of supply chain management—including strategy, structure, and operational capabilities—and performance. We imply that the strategy–structure supply chain management capabilities and performance (SS-M-CP) paradigm adopted was useful to understand the cumulative role of operational capabilities as well as supply chain management as an administrative department with authority to integrate organizational strategies and structures to influence the operational capabilities and leverage operational performance. Design/methodology/approach: Structural equation modeling was used to survey 138 strategic and operational supply chain managers of Brazilian and foreign companies headquartered in Brazil and associated with the capital goods industry. The hypotheses were validated, and the results showed the integration of organizational strategies and structures in supply chain management and a partial mediating factor of operational capabilities in the relationship between supply chain management and operational performance. Findings: The study validates the instrument that forms the strategies, structures, operational capabilities, and supply chain management for decision-making practices and analyses of potential mismatches in its implementation. The article contributes to the legacy of supply chain management research by providing theoretical understanding and empirical support for the SS-M-CP paradigm, which, when aligned, can improve and gain a competitive advantage.

Published: February 2025

As the impacts of climate change become increasingly evident, understanding the role of atmospheric aerosols in regulating Earth’s climate is crucial. Despite their significance, the optical properties of aerosols remain unclear to the general public and, particularly, to students in Physical and Earth sciences. This paper presents a didactic approach to exploring variations in aerosol optical properties, focusing on refractive indices and utilizing data from the National Aeronautics and Space Administration’s (NASA) AErosol RObotic NETwork (AERONET) under typical atmospheric conditions in central Amazon. The discussion presented here can be integrated into undergraduate and graduate university courses, linking Physics and environmental sciences and enhancing theoretical discussions in electromagnetism courses with observational data. The Amazon rainforest, with its dynamic atmospheric conditions influenced by seasonal changes, biomass-burning events, and long-range aerosol transport, provides a rich context for this analysis. Our study identifies seasonal patterns in aerosol optical depth, with biomass burning affecting light scattering at shorter wavelengths. African dust and smoke show strong absorption across a broader spectrum. We characterize the refractive index’s wavelength-dependent behavior for the different aerosol conditions, highlighting their unique optical properties. This interdisciplinary analysis contributes to a deeper understanding of atmospheric sciences and its implications for climate modeling and environmental assessment.

As diferenças estão relacionadas à definição da rede de suporte na implementação de tecnologias, bem como ao uso da inteligência artificial para a vigilância epidemiológica e consultas de triagem e rastreamento em teledermatologia nas unidades de cuidados primários em Portugal; no Brasil, destacam-se a institucionalização da Secretaria de Saúde Digital no Ministério da Saúde e a criação da Unidade Básica de Saúde Digital no contexto da Atenção Primária à Saúde. Ao permitir desvelar o uso de tecnologias para subsidiar as práticas, a análise minuciosa dos documentos pode contribuir para a implementação das políticas públicas e para a transformação digital democrática e inclusiva nos países.
Compreensões Fenomenológico-Existenciais acerca da Experiência de Suicídio na Infância: “E Existe?”
Authors: Melo Manuella Bila de , Azevedo Ana Karina Silva
Published: February 2025

Resumo: O suicídio na infância é um fenômeno invisibilizado e atravessado por diversos tabus, entre os quais o mito da infância feliz, que acredita que essa fase da vida seja marcada apenas por alegrias, sonhos e levezas, isenta, portanto, de dores e sofrimentos. Destarte, o presente artigo, fruto de uma dissertação de mestrado, tem como objetivo compreender a experiência do suicídio infantil a partir das narrativas de crianças que expressaram ideação ou tentativas de suicídio. Assim, em consonância com o modo de fazer pesquisa na fenomenologia, propomos um retorno às coisas mesmas a fim de tentar compreendê-las. Neste trabalho, apresentaremos trechos de encontros ocorridos com duas crianças participantes, que trouxeram em seus discursos desvelamentos de histórias marcadas pela solidão e de narrativas atravessadas por violências e conflitos, em razão da inospitalidade de um mundo no qual a existência tornava-se fardo e a morte apresentava-se na trama de significados como um caminho para lidar com o sofrimento.
O papel dos enclaves fortificados na reprodução de um modelo neoliberal de urbanização
Authors: Trindade Thiago , Amusquivar Érika
Published: February 2025

Resumo Qual o papel dos enclaves fortificados na reprodução de um modelo neoliberal de urbanização? De que forma exatamente um fenômeno está associado ao outro? Partindo do estudo paradigmático de Teresa Caldeira sobre a cidade de muros, nosso objetivo central neste texto consiste em analisar a relação de convergência entre os enclaves fortificados e o processo de neoliberalização do espaço urbano. A despeito de todos os avanços verificados na agenda de pesquisa sobre segregação urbana e espaço público nas últimas décadas decorrentes do trabalho de Caldeira, consideramos que a relação entre os enclaves fortificados e a neoliberalização do urbano ainda é um ponto subteorizado nesse debate. Nosso argumento é que, embora os enclaves não estejam, em sua origem, diretamente relacionados ao neoliberalismo, a sua consolidação na paisagem urbana tem contribuído de forma relevante para a reprodução de um modelo de cidade cada vez mais neoliberalizado, reconfigurando o espaço público e a própria vida urbana em conformidade com o ethos do mercado.

ABSTRACT Purpose This study aims to improve the existing knowledge about the application of Transcranial Direct Current Stimulation in rehabilitating Developmental Dyslexia, both alone and in conjunction with other therapeutic approaches. Research strategies The research was carried on the PubMed, Elsevier, LILACS and ERIC – Institute of Education Science. Selection criteria Peer-reviewed journal articles were included if published in English, Portuguese, and Spanish and be broken down from the research question devised by the PICO acronym. Data analysis Specific data collected according to delineation, summarized by descriptive analysis. Results Eleven articles were analyzed. Five of them associated tDCS with cognitive-linguistic or reading stimulation therapy. Assembly and application frequency parameters varied. The results indicated a positive effect on reading skills after the intervention in all of them. Conclusion The selected studies showed an improvement in reading speed and accuracy after active transcranial direct current stimulation, whether or not it combined with other cognitive-linguistic and reading stimulation. In some cases, the positive effects persisted up to six months after the intervention, making this a tool that can be used in the treatment of individuals with dyslexia.

ABSTRACT Purpose The aim of the study was to validate the Brazilian-Portuguese version of the Intelligibility in Context Scale (ICS-BP). Methods Sixty children (mean age in months = 55.05, SD = 4.2), 15 with parental or teacher concerns regarding their speech and 45 without concerns, underwent assessment using the phonology subtest of ABFW – Child Language Test. The percentage of consonants correct (PCC) was calculated and parents completed the ICS to evaluate their children's intelligibility with various communication partners. Descriptive statistics were obtained. Kruskal-Wallis and Spearman’ tests were used for independent group comparisons and correlation calculations, respectively. Linear regression models were established to predict PCC. Internal consistency was calculated using Cronbach's alpha. A Receiver Operating Characteristic (ROC) was used to analyse sensitivity and specificity. Significance was considered for p-values under 0.05. Results The majority of parents reported a mean score of 4.6 in a total of 5 (SD .10) at the ICS responses with different listeners, with better performance with other acquaintances and members of the family. The ICS demonstrated excellent internal consistency (α = 0.95). Positive correlations were found between ICS scores and PCC (r = .790) and a simple linear model was established between the ICS mean score and PCC. Sensitivity (0.98) and specificity (0.87) were considered high. Conclusion The ICS-BP indicated high psychometric values, suggesting that this instrument can be used to measure the intelligibility of Brazilian children.

ABSTRACT Purpose: Approximately 10% of breast cancer patients with localized operable disease experience recurrence. This study aimed to evaluate patients with early-stage breast cancer (TNM I and II) who underwent surgery without the need for neoadjuvant therapy. Methods: The total of 117 patients was included in the study: 104 without recurrence and 13 with recurrence. We analyzed various clinicopathological parameters, including body mass index, age at diagnosis, menopausal status, pesticide exposure, and tumor characteristics such as HER2 amplification, Ki67 index, molecular subtype, and histological grade. Results: Two primary subsets were identified as being associated with disease recurrence. The first subset (PC1) was characterized by HER2 amplification and metastatic disease, while the second subset (PC2) comprised premenopausal young women exposed to pesticides who had triple-negative tumors. While some of these factors are well-documented in the literature, pesticide exposure emerged as a notable regional factor contributing to poor outcomes in breast cancer patients. Conclusion: These findings underscored the significance of identifying local and regional risk factors when assessing recurrence risk in women with breast cancer, particularly in cases in which surgery is the primary treatment approach.

Abstract The glass industry stands at a critical moment in its evolution, confronted with the urgent need for decarbonization while striving to maintain operational efficiency and product quality. This paper delves into the current scenario of the glass industry, highlighting its significant contributions to global sustainability efforts while confronting substantial challenges in reducing carbon emissions. This paper looks at different ways to reduce carbon emissions in glass production, focusing on how much energy is needed to make glass and how important melting furnaces are to this process. These include using oxy-fuel, electricity, hydrogen, and possible combinations. Emphasizing the need for innovative approaches to mitigate refractory corrosion and other operational issues resulting from changes in combustion processes, the study underscores the importance of ongoing research and development in materials science and combustion technology. The paper looks at how the different parts of the furnace, its atmosphere, flame, and the refractory behave in complex ways. This helps us understand how to improve furnace performance and make them last longer so that the glass industry can be more sustainable.
