Published: December 2024

Shallow geothermal energy (SGE) is a promising green and sustainable energy source, gaining prominence in light of the dual-carbon target. This study investigated the SGE resources in the Yinchuan area. Suitability zones and the potential of SGE resources were determined based on the comprehensive analysis about thermophysical parameters, hydrogeological conditions, and geological environment. Our findings revealed that the effective thermal conductivity in the Yinchuan area surpasses those of other cities, indicating significant potential for SGE. The thermostat layer depth ranges from 40 to 60 m, with a geothermal gradient between 0.81 and 6.19 °C/100 m. Regions with poor adaptability for a borehole heat exchanger (BHE) are mainly distributed in the western and southern parts of the Yinchuan area, whereas moderately and highly adaptable areas are primarily located in the central and eastern areas, respectively. The total geothermal resource of the BHE in the Yinchuan area amounts to 1.07 × 108 GJ/a, generating significant economic benefits of 1.07 × 109 CNY/a and saving 1.09 × 106 t/a of standard coal annually. This initiative leads to significant reductions in CO2, SO2, and NOx emissions by 2.61 × 106 t/a, 1.86 × 104 t/a, and 6.57 × 103 t/a, respectively. Additionally, it results in potential savings of 0.309 × 109 CNY/a in environmental treatment costs. The methods and models used in this study have potential for similar geothermal surveys in arid and cold regions. The results also contribute essential insights for policy formulation and sustainable development strategies related to shallow geothermal resources in the Yinchuan area.

In our interconnected society, prioritizing the resilience and sustainability of road infrastructure has never been more critical, especially in light of growing environmental and climatic challenges. By harnessing data from various sources, we can proactively enhance our ability to detect road damage. This approach will enable us to make well-informed decisions for timely maintenance and implement effective mitigation strategies, ultimately leading to safer and more durable road systems. This paper presents a new method for detecting road potholes during low-light conditions, particularly at night when influenced by street and traffic lighting. We examined and assessed various advanced machine learning and computer vision models, placing a strong emphasis on deep learning algorithms such as YOLO, as well as the combination of Grad-CAM++ with feature pyramid networks for feature extraction. Our approach utilized innovative data augmentation techniques, which enhanced the diversity and robustness of the training dataset, ultimately leading to significant improvements in model performance. The study results reveal that the proposed YOLOv11+FPN+Grad-CAM model achieved a mean average precision (mAP) score of 0.72 for the 50–95 IoU thresholds, outperforming other tested models, including YOLOv8 Medium with a score of 0.611. The proposed model also demonstrated notable improvements in key metrics, with mAP50 and mAP75 values of 0.88 and 0.791, reflecting enhancements of 1.5% and 5.7%, respectively, compared to YOLOv11. These results highlight the model’s superior performance in detecting potholes under low-light conditions. By leveraging a specialized dataset for nighttime scenarios, the approach offers significant advancements in hazard detection, paving the way for more effective and timely driver alerts and ultimately contributing to improved road safety. This paper makes several key contributions, including implementing advanced data augmentation methods and a thorough comparative analysis of various YOLO-based models. Future plans involve developing a real-time driver warning application, introducing enhanced evaluation metrics, and demonstrating the model’s adaptability in diverse environmental conditions, such as snow and rain. The contributions significantly advance the field of road maintenance and safety by offering a robust and scalable solution for pothole detection, particularly in developing countries.
Pulsar Kick: Status and Perspective
Authors: Lambiase Gaetano , Poddar Tanmay Kumar
Published: December 2024

The high speeds seen in rapidly rotating pulsars after supernova explosions present a longstanding puzzle in astrophysics. Numerous theories have been suggested over the years to explain this sudden “kick” imparted to the neutron star, yet each comes with its own set of challenges and limitations. Key explanations for pulsar kicks include hydrodynamic instabilities in supernovae, anisotropic neutrino emission, asymmetries in the magnetic field, binary system disruption, and physics beyond the Standard Model. Unraveling the origins of pulsar kicks not only enhances our understanding of supernova mechanisms but also opens up possibilities for exploring new physics. In this brief review, we will introduce pulsar kicks, examine the leading hypotheses, and explore future directions for this intriguing phenomenon.

Published: December 2024

The development of leadership competencies is a current topic in the scientific community. The weaknesses detected in our study reflect the limited treatment offered to this area of work and the current struggle of rural elementary school directors in navigating the challenges of the digital era. The following methods and techniques were used at the theoretical and empirical levels: analytical–synthetic, historical–logical, inductive–deductive, systemic, documentary analysis, observation, surveys, interviews, and self-assessment scales. The systematized theory is based on the process of development of leadership competence in school directors as a dimension of educational quality. This research introduced a professional development strategy for the development of leadership competence in primary school directors consisting of three stages, with their objectives and actions contributing to raising the scientific methodological level of these management teams, including workshops, consultancies, accompaniments, and case studies, as well as monitoring their transformation. The proposed strategy improves the educational leadership skills of school principals, encourages mastery of content, and increases the degree of motivation and interest in management work. It is based on the diagnosis of their reality, and it includes the combination of improvement, methodological, and self-improvement actions to stimulate reflection and the active involvement of participants in their own transformation process.
Variations in Kojic Acid Production and Corn Infection Among Aspergillus flavus Isolates Suggest a Potential Role as a Virulence Factor

Published: December 2024

Kojic acid is a secondary metabolite with strong chelating and antioxidant properties produced by Aspergillus flavus and A. oryzae. Although antioxidants and chelators are important virulence factors for plant pathogens, the ecological role of kojic acid remains unclear. We previously observed a greater gene expression of antioxidants, especially kojic acid, by non-aflatoxigenic A. flavus when co-cultured with aflatoxigenic A. flavus. Aflatoxin production was also reduced. In this study, we investigated kojic acid production in 22 A. flavus isolates from Louisiana and compared them to four common A. flavus strains in liquid medium and on corn kernels. Corn kernel infection was assessed by quantifying the maize beta tubulin DNA content of the kernels using drop digital PCR (ddPCR). Maize beta tubulin DNA content decreased with increased corn kernel infection. Greater kojic acid production by A. flavus isolates coincided with greater levels of corn kernel infection. All isolates produced 60 and 700 times more kojic acid than aflatoxin and cyclopiazonic acid (a known virulence factor), respectively, which varied among sclerotial size categories. A. flavus strains with small sclerotia, which were rarely isolated from corn, produced the least kojic acid and infected corn kernels the least, while medium and large sclerotia strains—mainly isolated from corn—produced the most kojic acid and were more infectious. Non-aflatoxigenic isolates from Louisiana produced the most kojic acid. These results suggest that kojic acid is a potential virulence factor and may increase the pathogenic success of medium and large sclerotia-producing A. flavus, which could ultimately lead to more effective A. flavus biocontrol strains. Further studies are required to determine the effects that kojic acid has on the redox environment during corn infection and how the altered redox environment decreases aflatoxin production.

Published: December 2024

Background/Objectives: Vaccine hesitancy among immunocompromised patients is complex and not well understood. This study aimed to determine the rate of COVID-19 vaccine hesitancy among pediatric oncology and bone marrow transplant (BMT) patients and to understand associated factors. Methods: Parents of patients (≤18 years) with cancer or post-BMT completed the Parent Attitudes about Childhood Vaccines Survey. A COVID-19 vaccine hesitancy score (VHS-COVID) was calculated from 0 to 100 (higher scores indicating increasing hesitancy). A small group of patients (patients older than 15 years) were also surveyed directly. Results: Among 113 parent respondents, the majority were female (58%) and at least college/university educated (78%). The majority (73%) of patients had cancer (61% leukemia/lymphoma, 37% solid/CNS tumors), while 27% had received BMT for malignant and non-malignant conditions. Only 48% of patients had been vaccinated against COVID-19, compared to 88% of parents. Ineligibility due to phase of cancer/BMT treatment (27%), vaccine hesitancy (24%), and age (24%) were the top three reasons for not vaccinating against COVID-19. Only 13% of parents said they would “definitely vaccinate” if their child became eligible. VHS-COVID scores were higher for parents of patients in surveillance versus active therapy (mean 61 vs. 48; p = 0.03). Parents who had received fewer COVID-19 vaccine doses (0–1 vs. ≥2) were more hesitant toward all vaccines (p = 0.0002), COVID-19 vaccines (p = 0.0003), and influenza vaccines (p = 0.005). Conclusions: Vaccine hesitancy is common among this population and was demonstrated through beliefs (hesitancy scores) as well as vaccine uptake. Future work should focus on education targeting vaccine eligibility and engaging with vaccine hesitant families in the immunocompromised community.
Birth of a Healthy Monozygotic Twin Foal with Hydrops and a Dead Co-Twin

Published: December 2024

Transfer of in vitro-produced (IVP) equine embryos is associated with a higher incidence of monozygotic multiple pregnancies, but this remains a rarity. The outcome of monozygotic twin gestation is poor, and good management techniques are lacking. In addition, hydrops conditions are exceptional in horses, with hydroallantois occurring more frequently than hydramnion. Most hydrops conditions will lead to compromise or death of the foal and mare. A 6-year-old multiparous standardbred recipient mare, 332 days pregnant, diagnosed with a monozygotic twin and hydrops with a dead co-twin, gave birth with an assisted vaginal delivery. The dead foal, previously determined at 9 months by ultrasound, turned out to have the dimensions and hair corresponding to an 8-month-old foal. The other foal was born alive and considered healthy and normal-sized for its age. Both mare and foal were discharged from the clinic one week after parturition. This report is the first to describe the birth of a healthy foal born from a monozygotic twin pregnancy in the presence of hydrops, following transfer of a single IVP equine embryo. In addition, it is rare to find a non-macerated, non-mummified dead co-twin after fetal death at 8 months together with a healthy full-term foal.
Stress Distribution and Transverse Vibration of Flywheel Within Linear Elastic Range

Published: December 2024

Flywheels have been largely used in rotating machine engines to save inertial energy and to limit speed fluctuations. A stress distribution problem is created due to the centrifugal forces that are formed when the flywheel is spinning around, which leads to different levels of pressure and decompression inside its structure. Lack of balance leads to high energy losses through various mechanisms, which deteriorate both the flywheel’s expectancy and their ability to rotate at high speeds. Deviation in the design of flywheels from their optimum performance can cause instability issues and even a catastrophic failure during operation. This paper aims to analytically examine the stress distribution of radial and tangential directions along the flywheel structure within a linear elastic range. The eigenvalues and eigenvectors, which are representative of free vibrational features, were extracted by applying finite element analysis (FEA). Natural frequencies and their corresponding vibrating mode shapes and mass participation factors were identified. Furthermore, Kirchhoff–Love plate theory was employed to model the transverse vibration of the system. A general solution for the radial component of the equation of flywheel motion was derived with the help of the Bessel function. The results show certain modes of vibration identified as particularly influential in specific directions. Advanced time-frequency analysis techniques, including but not limited to continuous wavelet transform (CWT) and Hilbert–Huang transform (HHT), were applied to extract transverse vibration features of the flywheel system. It was also found that using CWT, low-frequency vibrations contribute to the majority of the energy in the extracted signal spectrum, while HHT exposes the high-frequency components of vibration that may cause significant structural damage if not addressed in time.

Published: December 2024

The discharge of nutrients and organic pollutants is increasing at an alarming rate, driven by the rapid development of human activities. This growing pollution is contributing to significant environmental issues, including eutrophication, making the treatment of wastewater essential before its release into the environment. Prior to being released into water bodies, treated wastewater must undergo rigorous laboratory analysis. For this reason, analysis using standard methods was carried out at the Laboratory Waterworks in Debrecen on multiple samples taken from various wastewater treatment plants in Hungary. The primary objective of this research was to assess the quality of effluents from (14) wastewater treatment plants and investigate their efficiency by measuring various physicochemical and microbiological parameters as indicators. The microbiological indicator monitored was the heterotrophic count (HPC) by estimating its total number. The results revealed that substantial removal efficiencies were demonstrated by parameters including total nitrogen (TN), chemical oxygen demand (COD), and biochemical oxygen demand (BOD₅), with reductions averaging 91%, 92%, and 87%, respectively. However, the reduction in nitrogenous compounds (nitrite NO2− and nitrate NO3−) was limited, indicating areas for process improvement. Recommendations for enhancing treatment efficiency are proposed to optimize the overall performance of the wastewater treatment plants.

Published: December 2024

Water resources are an important foundation for sustainable socioeconomic development. Revealing water use efficiency, the change in water use trends, and their driving mechanisms is essential for facilitating the scientific and reasonable prediction of water demand, thereby guiding the scientific planning and management of water resources. This study utilizes socioeconomic and water usage data from 65 countries spanning the years 1970 to 2020, employing the panel smooth transfer regression (PSTR) model to analyze the relationship between per capita total water withdrawal and per capita GDP. Additionally, Random Forest (RF) methods and empirical statistical analyses are implemented to identify the driving factors, control variables, and critical thresholds of water use trends in countries with different levels of development. The results show that: (1) there exists a nonlinear relationship between per capita total water withdrawal and per capita GDP on a global scale, with 70% of the countries exhibiting an inverted U-type trend in water usage; (2) the observed decline in per capita total water withdrawal in relation to per capita GDP is primarily driven by technological advancements and the optimization and enhancement of production structure; (3) common characteristics of OECD (Organization for Economic Cooperation and Development) countries that have reached their peak water usage include a service sector contribution to GDP exceeding 60%, urbanization levels at 70%, and per capita GDP surpassing USD 20,000. The observed changes in water use trends and the characteristic indicators associated with peak water usage, under conditions devoid of engineering interventions and resources constraints, can serve as valuable references for medium- and long-term water resources planning and water demand management in developing nations.
Spatiotemporal Variations of Precipitation Extremes and Population Exposure in the Beijing–Tianjin–Hebei Region, China
Authors: Lin Hao , Yu Xi , Lin Yumei , Tang Yandong
Published: December 2024

In recent years, precipitation extremes in China have increased due to global warming, posing a significant threat to human life and property. It is thus crucial to understand the changes in population exposure to precipitation extremes and the causes of these changes, since complex terrain areas are not accurately simulated by rain gauge interpolation data. Thus, we first used three satellite-based precipitation products—TRMM 3B42, CHIRPS, and CMORPH—combined with population data to analyze the spatiotemporal changes of precipitation extremes and population exposure from 1998 to 2019 in the Beijing–Tianjin–Hebei (BTH) region. In addition, the contributions of population, climate, and composite factors were quantified. The results showed that TRMM 3B42 outperformed the other two datasets in the BTH region. Over the past 22 years, the precipitation extremes in the central and northeastern regions, especially in Beijing, reached 2.5 days per decade, while the northern and southern regions showed a downward trend. The highest population exposure was mainly concentrated in central Beijing, most areas of Tianjin, and the urban centers of cities in southeastern Hebei province. Compared to the 2000s, a significant increase in exposure was observed in Beijing, Tianjin, and Zhangjiakou in the 2010s, whereas other regions showed negligible changes during this period. Climatic factors had the greatest influence on population exposure in most cities such as Qinhuangdao and Hengshui, where their climatic contribution exceeded 70%. While population change was more responsible for the increase in population exposure in the densely populated cities such as Tianjin, Handan, and Langfang, these cities contributed over 60% of the population. The interaction effect in Beijing and Tianjin was relatively obvious. The results of this study can provide a scientific basis for formulating targeted disaster risk management measures against climate change in the BTH region.

Published: December 2024

This study aims to explore aquaculture professionals’ perspectives on, attitudes towards and understanding of Mediterranean farm fish health management, regarding Artificial Intelligence (A.I.), and to shed light on the factors that affect its adoption. A survey was distributed during a major fish health management conference, representing more than 70% of Greek domestic production. A total of 73 questionnaires were collected, for which descriptive statistics and statistical analysis followed. Gender and age were shown to affect interest in A.I. and in viewing A.I. as a partner rather than a competitor. Age was additionally shown to affect trust in A.I. estimates and anticipation that A.I. will contribute to professional development. Education level shows no significant effect. Knowledge of A.I. is positively correlated with A.I. usage (r = 0.43, p < 0.05), as is interest in learning about A.I. (r = 0.64). A.I. usage is in turn positively correlated with eagerness to see its contribution (r = 0.72). Despite the fact that 64.4% characterized their knowledge as little or non-existent, 67.1% expressed interest in learning more, while 43.8% believe that A.I. will revolutionize aquaculture and 74% do not fear they will be replaced by A.I. in the future. The findings highlight the importance of targeted educational initiatives to bridge the knowledge gap and encourage trust in A.I. technologies.

Authors: Martiniak Vera Lucia , Oliveira Loraine Lopes de
Published: December 2024

O texto tem por objetivo apresentar as práticas de leitura e escrita pelas mulheres paranaenses no início do século XX, adotando como objeto de estudo os jornais que circulavam neste período. Na primeira república o ideal de mulher propagado era a que não criticasse, que evitasse comentários desfavoráveis e tivesse uma postura recatada. Diante da dificuldade do acesso aos livros escolares outras fontes de leitura surgiram neste contexto. Foi nesse período que os pequenos jornais se transformaram em gráficas e democratizou-se o acesso ao conhecimento por meio da leitura e escrita de textos em jornais, produzidos por mulheres. Em termos de procedimentos teórico-metodológicos, de caráter qualitativo, trata-se de uma pesquisa documental que tem como fonte histórica os jornais veiculados no início do século XX, no Paraná. A partir dos textos jornalísticos as escritoras denunciaram as relações sociais e contradições presentes na sociedade, marcadamente patriarcal, bem como as condições e oferta de educação às mulheres.

ILUSÃO CIENTÍFICA DA DIDÁTICA DA HISTÓRIA
Authors: Plá Sebastián , Bastos Flávio Pereira , Bomfim Marcus
Published: December 2024

As investigações no âmbito do Ensino de História têm tido pouca preocupação com o caráter epistemológico do conhecimento histórico escolar. Basicamente, elas estão centradas nas características do conhecimento histórico disciplinar e na sua correta transposição didática para a sala de aula em diferentes níveis educativos. Em contrapartida, até mesmo os estudos oriundos da Psicologia têm se concentrado nas formas gerais de aprendizagem ou de conhecimentos específicos. No entanto, é notável a carência de estudos teóricos e práticos que analisem o conhecimento histórico escolar como uma construção particular de conhecimento histórico. Sabemos que é um conhecimento diferente do conhecimento acadêmico. Este último, conhecemos também, com exaustivas revisões historiográficas, sua marca ideológica próxima ao nacionalismo. Mas ainda não temos clareza, por exemplo, se devemos analisar o conhecimento histórico escolar como uma derivação do conhecimento científico, ou se seu caráter político é, de fato, a condição de possibilidade para sua existência. Neste ensaio, reflito sobre as relações entre a historiografia profissional e o conhecimento histórico escolar. Apresento a hipótese de que se tem criado um brilho de cientificidade que produz três tipos de ilusões: a científica, a de neutralidade e a disciplinar. Cada uma delas estabelece relações de poder entre o ensino, a didática e a disciplina histórica que acabam por ocultar as características particulares da epistemologia do conhecimento histórico escolar.

El artículo se enfoca en la mediación cultural de los jesuitas al interior de las reducciones del Paraguay y Río de la Plata y analiza los mecanismos de control que ejercieron los Provinciales y Superiores de la Compañía de Jesús para asegurar la disciplina interna de los religiosos en la construcción de una sociedad cristiana/civilizada. También explora los conflictos y la resistencia indígena que tuvieron que enfrentar los doctrineros en el día a día de las misiones. Se consultó documentación privada de los padres Generales, Provinciales y Superiores que visitaron y escribieron sobre los indígenas en las misiones lo que nos permitió reconstruir una etnografía histórica de primera mano de sus protagonistas. Abordamos el intento de configurar un nuevo orden social dentro de las misiones y la manera en que se transformaron las relacionesinterétnicas entre los misioneros y los indios reducidos.
El concepto de voluntad en Pietro Pomponazzi. Una reconstrucción a partir del De fato, libero arbitrio et praedestinatione
Authors: Borelli Marcela
Published: December 2024

Este artículo tiene como objetivo desarrollar el concepto de voluntad en Pietro Pomponazzi, utilizando como texto central de análisis su tratado De fato, libero arbitrio et praedestinatione. Siguiendo la dinámica propia del pensamiento del autor, se exploran los alcances y limitaciones de la voluntad en el ámbito de la razón natural y la teología. Estos dos campos, delimitados con claridad y frecuentemente en conflicto en la obra de Pomponazzi, constituyen el fundamento para comprender las sutilezas de la voluntad. La presentación se divide en dos momentos: el primero aborda la voluntad en el ámbito de la razón natural y el segundo se adentra en su dimensión teológica. Por último, se adjunta la traducción de la quaestio “Utrum detur voluntas agens” del MS París, BnF, lat. 6449.
Ética social cristiana como fundamento apologético en la Legatio de Atenágoras
Authors: Valencia Marín Estiven
Published: December 2024

El margen práctico con el que se hace la defensa de los cristianos en tiempos de persecución comporta un aspecto significativo del pensamiento de Atenágoras, en el que descansa toda la aprobación para con los seguidores de Cristo. Sin embargo, se carece de estudios reflexivos respecto de una praxis cristiana como argumento apologético en este ateniense, estudios que transitarían desde un enfoque dogmático del cristianismo a uno más operativo. De aquí que, criticar la tradición religiosa de sus contemporáneos, procurar una vida pura y colaborar con la paz del imperio, implican un ideal ético en términos de crítica y de adhesión paradójicas que caracterizan al cristianismo de los primeros siglos.
Aspectos morfológicos do tumor estromal gastrointestinal comparado ao estadiamento da doença em adultos
Authors: Bittencourt Dayane Milagre , Pereira Henrique de Oliveira , Matiole Gustavo Henrique Bellose , Procópio João Paulo Martins
Published: December 2024

Os tumores estromais gastrointestinais comumente referidos pela sigla GIST (Gastrointestinal Stromal Tumor) representam os tumores mesenquimais mais comuns do trato digestivo, variando desde lesões de comportamento benigno à lesões malignas de cunho altamente disseminativo. As atuais classificações prognósticas dos GISTs, como a classificação de Fletcher, revelam discrepâncias entre o curso clínico real da doença e os prognósticos oncológicos deste tipo de tumor, reverberando a importância da avaliação dos parâmetros utilizados para prever o comportamento biológico do GIST, a fim de um estadiamento adequado com consequente emprego de estratégias terapêuticas eficazes para cada quadro. Constituindo 80% dos tumores mesenquimais do trato gastrointestinal, com 70% localizados no estômago, os GISTs são classificados histologicamente como originários das células intestinais de Cajal, contendo marcadores imunofenotípicos particulares, sendo o mais notável o CD117 (c-Kit). Também foi avaliado a presença de outros fatores como: PDGFRa (Fator de Crescimento Derivado de Plaquetas) e o gene supressor tumoral P53. As características referentes ao estadiamento deste tipo de tumor são múltiplas, sendo mais comumente utilizado o critério de risco desenvolvido por Fletcher, o qual estabelece dois fatores como parâmetros prognósticos: um macroscópico (tamanho do tumor) e outro microscópico (índice mitótico), inferindo o risco de malignidade, podendo variar de risco muito baixo, baixo, intermediário a alto. Este estudo traz uma revisão narrativa dos aspectos morfológicos do tumor estromal gastrointestinal em comparação ao estadiamento da doença em adultos, com o escopo voltado para a identificação dos fatores prognósticos responsáveis por pior evolução da doença, podendo-se realizar um melhor direcionamento terapêutico aos pacientes acometidos por tal patologia.

تم استخدام نموذج الأخبار في إطار المقدر الإحصائي (Garch-M) لدراسة سلوك أسعار الصرف للعملة المحلية. ودلت النتائج على أن سوق العملات الكويتي يتصف بالكفاءة، وأن الدينار والدولار مترابطان على المدى الطويل، بينما سعر الدينار متغير بالنسبة إلى العملات العالمية الأخرى. أما على المدى القصير، فإن هناك تغيرات ملموسة في سعر الصرف بين العملة الكويتية والدولار. لذلك يمكن الاستنتاج أن سعر العملة المحلية مربوط بسلة عملات وأن الدولار هو العملة الرئيسية في هذه السلة. ومن هنا يمكن التوقع أن التجارة الدولية والاستثمارات الخارجية الكويتية ستكون منحازة للأسواق الأمريكية. ولا يمكن أن تستمر سياسة تسعير العملة المحلية بهذا الشكل على المدى الطويل إذا كان النمو الحقيقي في الاقتصاد المحلي يقل بصورة ملموسة عما يماثله في الولايات المتحدة. لذلك على محددي السياسة النقدية والمالية العمل على توافق النمو الحقيقي في الدولتين عبر الزمن.

Authors: Amaral Alexandre Ribeiro , Monteiro Igor Angelo
Published: December 2024

O presente estudo tem por foco a contextualização entre a dicotomia do “mínimo existencial” e a “reserva do possível” associada às políticas públicas voltadas para a Primeira Infância. Para isso, foi realizada uma revisão teórica sobre o papel do Estado, suas políticas de governo e a expectativa da sociedade visando a disponibilidade dos direitos à população. Ao desenvolver o estudo, considerou-se os direitos relacionados à Primeira Infância como Direitos Sociais, essenciais ao ser humano, capazes de promover a saúde, a educação, o lazer e o crescimento saudável. O tema possui relação com a problemática enfrentada por diversos gestores públicos que se veem obrigados a proporcionar ações públicas garantistas enquanto há escassez de recursos financeiros capazes de financiar todos os custos necessários. Foram consultados dados abertos na rede mundial de computadores que proporcionaram uma visão numérica sobre as políticas públicas na Primeira Infância, compartimentalizada pelas regiões do Brasil, mais especificamente contendo dados relacionados à educação e saúde. Outro ponto abordado foi a atuação do poder judiciário frente as questões da reserva do possível. A metodologia utilizada baseou-se em consulta a fontes bibliográficas sobre o tema, consulta e análise à base de dados secundários com fins de obter um panorama nacional da situação da Primeira Infância no país, concluindo que determinados direitos básicos voltados ao público infantil não podem ser relegados pelo poder público.

Kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan untuk meningkatkan kesadaran dan daya antisipasi Calon Pekerja Migran Indonesia (PMI) Perempuan di Banyuwangi terhadap kerentanan jalur non-resmi dalam bekerja ke luar negeri serta memperkuat mekanisme mitigasi penempatan PMI non-prosedural. PkM ini dilaksanakan bermitra dengan Dinas Tenaga Kerja, Transmigrasi, dan Perindustrian Banyuwangi serta Pos Pelayanan Perlindungan Pekerja Migran Indonesia (P4MI). Urgensi kegiatan ini muncul setelah teridentifikasinya kelambanan birokrasi (bureaucratic inertia) antar stakeholder yang disebabkan oleh perbedaan struktur, garis kewenangan, dan kekakuan prosedur operasional baku (SOP) dalam penanganan kasus PMI, yang berdampak pada tingginya jumlah penempatan PMI ilegal. Untuk mengatasi masalah ini, Fakultas Ilmu Sosial dan Ilmu Politik terlibat langsung dalam memberikan edukasi kepada masyarakat mengenai bahaya jalur non-prosedural yang diakibatkan oleh kelambanan birokrasi dalam penanganan migrasi. Kegiatan PkM ini dilaksanakan di Desa Tembokrejo, Kecamatan Muncar, Kabupaten Banyuwangi melalui metode sosialisasi dan pelatihan. Tujuan utama dari sosialisasi dan pelatihan ini adalah untuk mengurangi kerentanan Calon PMI Perempuan terhadap jalur migrasi non-prosedural, serta mendorong mereka untuk memilih jalur migrasi yang aman dan prosedural. Pelatihan ini diharapkan memberikan dampak positif bagi masyarakat dengan meningkatkan kesadaran dan kemampuan antisipasi mereka, sehingga mereka dapat menghindari bahaya bekerja melalui jalur non-resmi dan tetap menggunakan jalur yang prosedural dan aman dalam bekerja di luar negeri.

Para evaluar la participación del GMPc en la conducta sexual de la cerda inducida por estrógenos, determinamos la relación entre la dosis del estradiol libre (Eli) administrado en el ventrículo lateral derecho (RLV) y la conducta sexual (respuesta de inmovilidad), posteriormente se evaluaron cambios inespecíficos de una dosis de GMPc (dbGMPc), para finalmente estudiar su participación en la respuesta de inmovilidad, inducida por la dosis efectiva mínima (DEM) de Eli.  Con este objetivo, 78 cerdas fueron ovariectomizadas (ovx) e implantadas con una cánula en el RLV, (Según la Norma Oficial Mexicana para el cuidado animal). Inicialmente determinamos la dosis efectiva (ED) mínima (3,2 µg) y la máxima (16 µg) de Eli, posteriormente, seleccionamos una dosis de dbGMPc (sin efectos inespecíficos), finalmente utilizando por infusión la ED mínima en el RLV, se indujo la conducta de inmovilidad en cerdas ovx, la adición de dbGMPc al Eli mostro un incremento en la conducta de inmovilidad disparada por el Eli (h48; p<0.01), estos resultados muestran in vivo que la receptividad sexual en la cerda depende de la dosis de Eli  y la participación del GMPc en el disparo de la conducta sexual en la cerda como una ruta complementaria (no genómica) del E2.
