Obra que responde a la pregunta: ¿para qué sirve la planeación en una ciudad compleja y marcada por desigualdades? Es resultado de una amplia discusión entre las personas integrantes de la Red de Derechos Humanos y Planeación en la Ciudad de México, en torno a un proceso de planeación sin precedentes en la capital mexicana (2021-2024). No se trata solamente del seguimiento al proceso de consulta ciudadana sobre el futuro de la ciudad, sino de un análisis riguroso sobre sus problemáticas y alternativas sociales, políticas, económicas, ambientales y espaciales. Los 11 capítulos que la integran abordan las inconsistencias del proceso planificador, las múltiples problemáticas urbanas y metropolitanas y, sobre todo, destaca la agenda de los derechos humanos como la ruta a seguir. De esta forma, la obra va más allá de los intentos fallidos de consulta de los instrumentos y, en su lugar, sostiene la relevancia de la planeación como proceso continuo y de carácter sustantivo para el devenir de la ciudad.
Prólogo: Las paradojas de la planeación como preámbulo a sus inconsistencias, problemáticas y alternativas
Authors: Pino Hidalgo Ricardo Adalberto
Published: December 2024

Se reflexiona en torno a la planeación urbana mexicana y en particular la correspondiente a la Ciudad de México. En particular, la planificación de ciudades ha logrado trascender los ámbitos gubernamentales y la academia, alcanzando un interés creciente entre diversos sectores de la sociedad que han visto en ella un importante instrumento que, de mantenerse exclusivamente en manos del poder político y económico puede constituirse en un vehículo de control social y fuente de injusticias socioespaciales y enriquecimiento; mientras que, de llegar verdaderamente a manos de la ciudadanía, podría conformarse en una herramienta capaz de abonar a la construcción de una ciudad más justa y encaminada a alcanzar a plenitud los derechos de todos y todas a la ciudad.
Application of geophysical methods in subsurface mapping and mineral exploration: Adiyaman-Besni region, Türkiye
Authors: Yalçın Cihan , Karan Ali
Published: December 2024

The present study aimed to delineate subsurface features and identify prospective metallic mineral deposits in the Adıyaman-Besni area, situated within the Southeastern Anatolian Thrust Belt of Turkey. This region, characterized by ophiolitic mélanges and volcanic massive sulfide (VMS) deposits in its geological framework, possesses significant mineralization potential, encompassing copper, lead, and various other sulfide minerals. Utilizing the combined methodologies of Induced Polarization (IP) and Electrical Resistivity Tomography (ERT), a comprehensive electrical mapping of the subsurface structures was conducted, revealing that mineralized zones had low resistivity and high chargeability. The findings indicate that the combined use of IP and ERT techniques yields excellent precision in accurately delineating the features of sulfide mineralization and the peripheries of mineral deposits. This study offers fundamental data for the economic assessment of prospective mineral deposits in the Adıyaman-Besni region and underscores the benefits of IP and ERT techniques in subsurface mapping and mineralization delineation investigations. The mineralized zone has low resistivity (< 50 ohm-m) and strong chargeability (> 30 ms), according to geophysical tests. It also offers a methodological framework for subsequent mineral exploration research in analogous geological formations.
An empirical analysis of the correlation between philosophical perspectives and atheism
Authors: Smida Nizar , Jemal Bassem , Ebead Said Aly , Zaghloul Sabrin
Published: December 2024

Our main objective in this research is to affirm that philosophy, in its true essence and depth, has never been inherently opposed to religion. Rather, the turn toward atheism within philosophy represents isolated, personal stances, often reactionary in nature, and not rooted in genuine intellectual reflection, which the Qur’an encourages and calls people to adhere to. Our endeavor is to show that the call to atheism is foreign to reason, understood as a sound faculty or a sense linked to the pursuit of truth, as previously demonstrated by Descartes in his focus on the principles and methods of philosophical inquiry. To facilitate the achievement of these goals, we have employed several methodologies, primarily the structural method, which helps us analyze selected texts, this methodology enables the understanding of the elements within the studied positions, the relationships that link them, and the underlying implications upon which they are based. We will apply this method practically when analyzing conceptions that reject religion, uncovering the framework underpinning each conception. This approach facilitates comprehension by examining the rational foundations that support each interpretation of religion and later pave the way for its denial or transcendence. the historical method, which allows us to trace the development and dissemination of atheism, this approach is based on the premise that every sensory or intellectual phenomenon has an origin defined by time and place, evolving through transformations and additions over time. By employing this method, we can trace the development of various interpretations of religion and understand the intellectual accumulations shaped by successive historical periods, and the deconstructionist method, through which we identify the contradictions and flawed principles underlying atheistic arguments, this method allows for in-depth critique of the foundations, developmental trajectories, and final outcomes of phenomena. It also provides a means to establish new perspectives—whether by modifying the existing model, recontextualizing it, or replacing it with an entirely new framework. The importance of re-examining the relationship between philosophy and atheism stems from the profound influence of certain philosophical positions and their negative views on religion within various atheistic currents, especially contemporary ones. Contemporary atheism today poses a threat to religion as a symbolic human system, rich in a value-laden framework that upholds the essence of humanity in an era dominated by materialism and the absence of values. The central question of this research is: Can the human being truly achieve existence independently? Or can one live in this world isolated from all influential forces, including the creative and divine force?
Corruption as a barrier to sustainability
Authors: Malatyinszki Szilárd , Zéman Zoltán , Kálmán Botond Géza
Published: December 2024

This study investigates how corruption impacts sustainability in African countries. Using public databases, the research draws on the African Development Bank’s corruption indicators and the World Bank’s financial inclusion metrics. The findings reveal that as financial inclusion increases, particularly through the use of digital financial services, perceptions of corruption decrease. However, economic growth paradoxically correlates with an increased perception of corruption due to rising consumption demands. The study concludes that promoting financial literacy, along with robust governance, is essential for combating corruption and fostering sustainable development.
Prediction of Compressive Strength of Recycled Aggregate Concrete Using Hybrid Decision Tree Models
Authors: Wang Chenguang
Published: December 2024

In order to reduce the impact of construction waste on the environment, recycled aggregates are widely used in concrete. The compressive strength of recycled coarse aggregate is a significant indicator of concrete performance. To improve the prediction of the compressive strength of recycled coarse aggregate concrete, a model for compressive strength prediction based on a hybrid decision tree model is proposed. The recycled aggregate concrete data was collected and preprocessed, and the model parameters were optimized using the tree structure probability density estimation Bayesian optimization (TPE-BO) method. It was verified by example comparison that the prediction correlation coefficients of the TPEXGBoost model in the training and test sets were 0.9715 and 0.9543, and the RMSEs were 1.5122 and 2.1598 MPa, respectively, which could improve the model performance to a certain extent. The replacement rate of recycled fine aggregate should not exceed 20% and the replacement rate of recycled coarse aggregate should not exceed 60% when creating recycled concrete. The compressive strength prediction model provides a foundation for researching and practicing recycled coarse aggregate concrete and a novel way to predict the performance of recycled concrete.

As the world faces the impact of big data, calligraphy education in colleges and universities also faces opportunities and challenges. This paper proposes the intelligent evaluation technology of calligraphic works and the intelligent interaction technology of calligraphic works as the cultural inheritance strategy in calligraphy education. The tracking algorithm combining Faster R-CNN and KCF is used to get the calligraphic writing trajectory, calculate the difference characteristics between the movement trajectory of the brush and the model, and make regression predictions on the copying scores through the regression model to get the intelligent scores of the calligraphic works. The model of rice paper, brush, ink, and particle diffusion is established to realize GPU-accelerated real-time drawing process for calligraphy works, and the interaction system is built based on the Cocos2DX framework. Taking 120 first-year students majoring in Chinese language and culture at the University of Q as research subjects, we conducted a study on the cultural inheritance of calligraphy education. The mean value of comprehensive ability in calligraphy learning of students in the experimental class was about 4.48, which was higher than that of the control class by 1.035. Among the positive psychological qualities in calligraphy learning, the mean values of psychological dimensions of the experimental class were generally higher than those of the control class, which showed a significant difference (P<0.05). For the evaluation of intuition and interest in calligraphy teaching methods, the experimental class evaluated the mean values of 4.17 and 4.28, which were higher than those of the control class of 1.1 and 1.82.

Authors: Huang Wei
Published: December 2024

The implementation of the audit supervision system in accordance with the law for nearly 20 years has demonstrated its significant role in maintaining the reform, development, and stability of colleges and universities. After extracting relevant financial data from the database, this study creates a maximum classification tree by splitting nominal variables in the ID3 incremental learning decision algorithm. It then combines incremental and categorical learning modules to establish the financial management and early warning system of colleges and universities. Subsequently, the innovation platform for university financial management and audit supervision is designed by combining the system with the objectives of university financial audit supervision. After testing, the function and performance of the platform are normal, and it can be applied to achieve financial management and audit supervision in universities. After applying the innovative platform proposed in this paper, the overall score of financial management and audit supervision in University E increased from 11.97 in 2018 to 16.16 in 2023, which is within the good and excellent range. This paper holds practical value in effectively enhancing the effectiveness of audit supervision in colleges and universities, further promoting the construction of internal systems and financial management in these institutions, and improving the efficiency of the use of educational funds and school operations in these institutions.

Authors: Shen Yizhuang
Published: December 2024

This paper combines the current direction of library digital resource sharing platform development, puts forward the library digital resource sharing platform for knowledge management, determines the overall design ideas and framework of the platform, and then adopts the hybrid recommendation algorithm to optimise the platform of this paper. Determine the data sources and evaluation indexes, conduct comprehensive simulation analysis and questionnaires, and jointly verify the knowledge management-oriented library digital resource sharing platform. It can be concluded from the validation that the difference between the coverage rate of the hybrid recommendation and the coverage rate of the traditional recommendation method is small, and its value is 0.1015. The hybrid recommendation algorithm effectively improves the coverage rate of resource sharing on this platform, and when the number of users online at the same time is 200, the processing time of the server is 98.91ms, which makes the platform fully capable of running smoothly. The difference between the five dimensions of this paper’s platform and the traditional platform ranges from 2 to 158 at the time of satisfaction (A), which comprehensively demonstrates the superiority of this paper’s platform. In order to better promote the construction of a knowledge management-oriented library digital resource sharing platform, two optimisation strategies are proposed.
The Role of Religious Attributes in the Manifestation of Empathic Anger in Generation Z Students From the West University of Timisoara
Authors: Tudoran Marina Alexandra , Țîru Laurențiu Gabriel , Neagoe Alexandru
Published: December 2024

The existing literature on empathic anger presents a variety of perspectives. While some scholars view it as a constructive expression of anger, others delineate it as a specific form of emotional empathy. On the other hand, the role of religion in society remains a topic of interest among researchers due to the beneficial impact it has on the emergence of prosocial behaviors. These findings suggest that religion plays a significant part in maintaining social order and cohesion. Nevertheless, only a limited number of studies have addressed empathic anger within the context of religion. In light of the aforementioned considerations, the first part of the study aims to ascertain the degree of empathic anger, religious attitude, and level of religious involvement among Generation Z students. The second part of the study examines the influence of religious components on the manifestation of empathic anger in respondents. The results indicated that although empathic anger is only correlated with religious behavior, religious attitudes also exert some influence on the manner in which students relate to injustice.

Authors: Dorić Barbara , Primorac Dinko , Bach Mirjana Pejić
Published: December 2024

Background and Purpose

To encourage petroleum industry development, a country needs to set up a regulatory framework that standardizes investment conditions. The objective of the research was to investigate the determinants of government effectiveness in the petroleum sector.

Design/Methodology/Approach

Multiple regression analysis was conducted to investigate if government effectiveness in the petroleum sector is influenced by the country’s political stability, regulatory quality, the intensity of petroleum exploration and production activities, government take, and type of contract used. Artificial neural network analysis was additionally conducted to identify the importance of independent variables.

Results

Political stability, regulatory quality, government take attractiveness, and the intensity of petroleum activities positively influence government effectiveness. A more attractive government take enhances effectiveness, while the type of contract for awarding petroleum rights did not significantly impact effectiveness. Artificial neural network analysis revealed that the most important variables were regulatory quality and political stability.

Conclusion

The research concluded that political stability, regulatory quality, and the intensity of petroleum activities are key factors in enhancing government effectiveness in the petroleum sector. These findings have practical implications, as they emphasize the importance of stable and well-regulated environments for achieving higher government effectiveness in the petroleum industry. This equips policymakers and industry professionals with actionable insights for improving the sector’s performance.

Published: December 2024

Objetivo: identificar los medios de vida que contribuyen a superar la pobreza alimentaria rural. Metodología: la investigación se realizó en tres comunidades de Zacapoaxtla, Puebla. Se aplicó un cuestionario a una muestra de 96 hogares con características indígenas. Se utilizó análisis multivariado para generar un índice, en escala de cero a uno, de los medios de vida, que se correlacionó con la línea de pobreza alimentaria. Resultados: el valor máximo del índice de los medios de vida correspondió al capital físico y el más bajo, el capital natural. El modelo de regresión Tobit mostró que los capitales financiero, social, humano y el físico, fueron significativos en explicar la pobreza alimentaria. Inicialmente se consideró la línea de pobreza alimentaria y no alimentaria, pero de la muestra solo un par de casos alcanzaron esta última. Limitaciones: la medición de la pobreza alimentaria utilizó un enfoque indirecto, basado en el ingreso del hogar. Sin embargo, un método multidimensional podría explicar de mejor forma la condición de pobreza de los hogares. Conclusiones: el capital financiero fue el que más contribuyó para superar la línea de pobreza alimentaria rural, por los apoyos gubernamentales y las remesas. El capital natural no contribuyó significativamente por el tamaño del predio, régimen de temporal y la tecnología.

Published: December 2024

Objective: To determine the association between social determinants of health (SDH) and noncommunicable diseases (NCDs) in a rural primary care population.
 
Theoretical Framework: A solid foundation is provided through definitions and theories that support the study and make it possible to understand the topic and context of the research.
 
Method: Cross-sectional, multicenter study, with stratified, randomized, probability sampling in 430 adult users of primary care centers in a Peruvian health care network. The independent variable was adverse DSS (DSS/A), measured with the Steps to Better Health Questionnaire (STBH-Q) and the dependent variable was NCDs.
 
Results and Discussion: Of the participants, 52.6% identified DSS/A; 47.7% poor access; 55.3% dissatisfaction with employment, finances and education; 56% insecurity in the home and community; 51.4% latent concern for physical and mental health; and 56.5% inadequate family and childhood. The overall prevalence of NCDs was 23%. The DSS/A revealed significant association (p=0.001) with NCDs (PR=1.91: 95% CI: 1.31-2.79).
 
Research Implications: SHD translate into social needs that influence people's health. Therefore, it is necessary to detect them in order to address them in the context of primary care.
 
Originality/Value: Studies exploring the association between DSS and NCDs in rural contexts are scarce, and this gap in knowledge limits the capacity of the state and health systems to intervene.

Authors: Carneiro Carla Renata de Oliveira , Ribeiro Hebe Morganne Campos
Published: December 2024

Objective: Present the number of cases of Diseases Related to Inadequate Environmental Sanitation – DRSAI present in the urban area of ​​Belém do Pará.
 
Theoretical Framework: The emergence of DRSAI is associated with problems of basic sanitation coverage and is organized into 5 categories: by feco-oral transmission; by insect vector transmission; transmitted through contact with water; related to hygiene; geohelminths and taeniasis. The high incidence of DRSAI is part of the Brazilian reality, mainly reaching the population lacking better living conditions, existing in Belém do Pará, in the Northern Region of Brazil.
 
Method: To obtain the spatial distribution of the number of cases, data were provided by the Municipal Health Department of Belém for the diseases: typhoid fever, hepatitis A, leptospirosis, dengue, zika and chikungunya, between the years 2015 and 2022. The qualitative part sought information and data in published articles, books and reports.
 
Results and Discussion: In the spatial analysis, the Guamá neighborhood had the highest number of occurrences in 5 of the 6 DRSAI surveyed, with the exception of chikungunya, whose neighborhood with the highest number of cases was Águas Lindas. Other neighborhoods also stood out, such as Pedreira, Sacramenta, Marco and Marambaia, neighborhoods that also have the common characteristic of a high population contingent.
 
Implications of the Research: The results can assist in strategy plans for public policies in the municipality, mainly related to the reduction of DRSAI cases and actions to implement basic sanitation.
 
Originality/Value: This study contributes to showing that neighborhoods with a high population contingent associated with unsatisfactory numbers in relation to basic sanitation, points to a public health situation that requires attention from the Public Power for actions to combat it.

Published: December 2024

In the current study, an aluminum alloy A356-based hybrid metal matrix composite with red mud and titanium carbide reinforcements is fabricated using a liquid processing route namely the stir casting method. The machining characteristics along with the suitable electrode material during the electric discharge machining of the fabricated composite are determined. The authors are interested in studying the effects of various electric discharge machining (EDM) input parameters like peak current, the voltage on time, and gap voltage affecting the material removal rate (MRR) and tool wear rate (TWR) at the time of machining. Levels of input parameters to conduct the experiments are considered from the literature review, machine capacity, and pilot experiments. To predict the suitable electrode material for the newly fabricated heterogeneous composite material, different electrode materials namely brass, copper, graphite, and stainless steel are used to perform the experiments. Further, the surface roughness of the machined surface is measured and compared for different electrode materials used in the present work. From the results, it has been observed that copper electrode followed by stainless steel electrode show the least tool wear rate (TWR), while brass exhibited the highest TWR. Stainless steel electrode has shown a 90.73% reduction in TWR when compared with brass which has shown the largest TWR. But the Graphite electrode had shown a 57.19% improvement in MRR when compared with stainless steel which had produced a lower value of MRR.

Published: December 2024

This research investigated the tribological performance of phosphonium-based ionic liquid Tri hexyl tetra decyl-phosphonium bis (2, 4, 4-trimethylpentyl) phosphinate (IL) when used as an additive at a concentration of 1wt% to Cotton seed oil (CSO), Rattan Jot oil (RJO), Waste Cooking oil (WCO) and Polyalphaolefin (PAO) at different operating conditions. The results were compared with conventional PAO base oil. The tribological performance of all lubricants was studied using a Vertical Universal Testing Machine (MMW1A) and wear scar diameter were measured using an electronic microscope OLYMPUS DX-1000. The results indicated that the addition of ionic liquid further enhanced the tribological performance in terms of wear for all bio-lubricants except for waste cooking oil. However, the addition of ionic liquid does not have much effect on the tribological performance of PAO. Rattan Jot oil was found to have the best tribological properties with the addition of ionic liquid.

Published: December 2024

The objective of this study was to evaluate the performance of a lubricant by defining the value of the friction factor at the interface. Ring compression tests were performed at room temperature for a typical steel in mechanical forming applications. The samples were compressed to 10%, 25% and 40% of their initial height with a constant speed of 3 mm/min. Using the FORGE NxT2.1 finite element software, an optimization procedure was carried out to reduce the computational cost, then simulations were performed by varying the values of the friction factor so that a cost function was minimized. The cost function for this optimization considers a relationship between the internal and external diameters of the specimens for the simulated and experimentally measured cases. The results showed a good relationship between experiments and numerical analysis. After the optimization was performed, the value of the friction factor m varied between 0.001078 and 0.0873, depending on the dimensional measurement method used.
Case Study: Correlations Between Curve Squeal, Weather Conditions, and Traction in a Tram Loop
Authors: Valena Martin , Omasta Milan , Klapka Milan , Galas Radovan , Navratil Vaclav , Krupka Ivan , Hartl Martin
Published: December 2024

This study explores the relationship between the coefficient of traction (CoT) and squeal noise parameters on a tram line loop, focusing on the influence of weather conditions. An automatic noise module was placed near a tram loop known for noise complaints. This module distinguishes between squeal and flange noise, recording their duration, root mean square (RMS) sound pressure level, and maximum sound pressure level when a threshold in the appropriate frequency band is exceeded. Concurrently, weather conditions were monitored, and the CoT on the rail was measured using a BUT rail tribometer. The findings reveal a notable correlation between the CoT and the duration of squeal noise, while the association with sound pressure levels was less pronounced. An increase in CoT was observed with rising relative humidity, which may be attributed to increasing temperature throughout a sunny April day, while absolute humidity remained almost constant. Furthermore, noise parameters rose with higher relative humidity and showed an inverse relationship with temperature. These findings suggest that weather conditions, particularly relative humidity and temperature, influence both the CoT and noise parameters on tram lines.
Evaluation of the Tribological and Corrosion Resistance Properties of 24-Bilayer TiN/TiAlN Coatings in Simulated Body Fluid
Authors: Arnulfo Aperador Chaparro Willian , Cesar Caicedo Angulo Julio , Bautista-Ruiz Jorge
Published: December 2024

The tribocorrosive behavior of [TiN/TiAlN] coatings, consisting of 24 bilayers with a bilayer period (Λ) of 125 nm, was evaluated. There is a lack of studies on the tribocorrosion of TiN/TiAlN multilayer coatings applied to metallic prostheses. These coatings were obtained using a reactive RF magnetron sputtering system and deposited onto a Ti6Al4V alloy. This study represents the first evaluation of the tribocorrosive behavior of these coatings in simulated physiological environments. Various characterization techniques were employed, including X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), pin-on-disk testing, electrochemical impedance spectroscopy (EIS), and Tafel curves. The coatings exhibited a face-centered cubic (FCC) structure, characterized by a partial arrangement of Ti and Al atoms. The research is motivated by the need for tribocorrosion-resistant coatings to enhance the durability of metallic prostheses. The results demonstrated a friction coefficient of 0.053 and a corrosion rate of 0.025 µm/year, highlighting the effectiveness of the coating. Changes in roughness were observed; however, no significant alterations in its formation were noted.

Published: December 2024

In order to improve mechanical and tribological qualities, this study investigates the innovative use of stir-casting to integrate carbon nanotubes (CNT) and nano clay (NC) as dual reinforcement materials in Al6063 matrix composites. Combining CNT (0–2%) with NC (0–2%) in a synergistic way presents a special chance to capitalise on each filler material's particular properties. With an increase in CNT and NC on the Al6063 matrix, mechanical parameters like tensile strength, hardness, flexural strength, and compressive strength rise from 225-245 MPa, 45-74 BHN, 218-298 MPa, and 140-152 MPa. Tribological characteristics were analyzed through pin on disc (tribometer), with varying loads (5 N - 10 N), velocity (0.209 m/s - 1.047 m/s) and sliding distance (253.32-753.98 m). The results demonstrate that the addition of 2 wt% CNT and 2 wt% NC reduces the specific wear rate value and increase the coefficient of friction. A decrease of wear rate value 0.0162 mm3/m and increase in COF 0.70 was observed at maximum load of 10 N and velocity of 0.209 m/s corresponding to 2 wt% of CNT and NC incorporation. The homogeneous distribution of fillers in the metal matrix, tensile fracture, distinct wear modes, and the importance of CNT/NC in changing the wear process from abrasion to delamination are all demonstrated by SEM analysis.
ГАЙДЕҐҐЕРІВСЬКИЙ ПАРМЕНІД: ПЕРСОНАЖ ГАЙДЕГЕРІВСЬКОЇ ФІЛОСОФІЇ ЧИ АВТЕНТИЧНИЙ МИСЛИТЕЛЬ?
Authors: ВОЗНЯК Степан
Published: December 2024

Анотація. Мета роботи полягає у розкритті сутнісних рис та характеристик західного мислення через гайдеґґерівську інтерпретацію ідей Парменіда. Методологія статті передбачає занурення у історико-філософську площину, що зумовлює використання класичних методів понятійного, текстологічного, інтерпретативного та логіко-структурного аналізу. Також необхідною методологічною засадою дослідження є принцип єдності історичного і логічного. Наукова новизна. У статті розгортається смислова конотація між автентичними висловлюваннями Парменіда і їх гайдеґґерівською інтерпретацією. Внутрішня напруга та актуальність даної конотації схоплюється через гайдеґґерівський вирок сучасності, котрий звучить як «ми ще не мислимо», хоча історично західне мислення розгортається з установки на тотожність мислення і буття. Доводиться, що, попри загальне академічне визнання Парменіда моністом, у його наративі тотожності мислення і буття присутня внутрішня подвійність, котра в подальшому формує розрив між буттям і мисленням, оскільки мислення буття утворює раціональні надбудови над останнім, що затьмарюють буттєву неприхованість специфічною «владою мислення над буттям». Висновки. Попри зазначену дуальність і зафіксований розрив, цілісна гармонія цих вимірів можлива, але лише за умови повного розуміння буття у ракурсі гайдеґґерівсько-парменідівської неприхованості, на противагу абстрактним редукціям чистої логіки, що виключають діалектичне мерехтіння буття та існування, або прямолінійному біологічному тлумаченню духовного життя людини в контексті психофізіологічного складу людського організму. Відповідно до Гайдеґґерового Парменіда, світ відкривається нам, і це «включає» нашу реакцію на нього, за умови, що ми відповідним чином налаштуємо свій погляд. Таким чином, залучення до простору філософського дискурсу розширює наші можливості насолоджуватися багатовимірним розмаїттям людських зусиль і починань у всіх формах і сферах.
Integrando farmacologia de rede e docagem molecular para avaliar o potencial terapêutico da tangeritina contra o meduloblastoma
Authors: Clemente de Melo Nicolly , De Carvalho Lucas Miguel
Published: December 2024

A tangeritina é uma flavona antioxidante com efeitos anticancerígenos capazes de inibir o desenvolvimento e a progressão celular cancerígena. Diante dessas propriedades e da relevância estatística do câncer no sistema nervoso central de 11.490 casos a cada 100 mil habitantes entre os anos 2023 e 2025, o estudo de compostos naturais aplicado aos tumores cerebrais surge como uma abordagem promissora. Por apresentar um diagnóstico e tratamento precoce desafiadores, com ocorrência de metástases que representam a principal causa de mortalidade, o meduloblastoma, câncer principalmente pediátrico, exige mais pesquisas direcionadas ao desenvolvimento de novas terapias que possam diminuir os casos de metástases e efeitos colaterais provenientes das terapias convencionais. As análises de rede de interação proteína-proteína (PPI) revelaram alvos terapêuticos como EGFR, AKT1, SRC, GSK3B, PARP1, MMP9, PTGS2, MCL1 e ABCB1. Após a clusterização, a docagem molecular da proteína SRC confirmou que a tangeritina apresentou uma energia de ligação satisfatória de -6,33 kcal/mol e RMSD igual a 0, indicando uma alta afinidade com o receptor. O enriquecimento funcional das vias de sinalização indicou a relevância das vias EGFR-TKI, PI3K-Akt, Carcinogênese química - espécies reativas de oxigênio, Via de sinalização de estrogênio, Via de sinalização Ras, Via de sinalização MAPK e Via de sinalização FoxO. A modulação dessas vias pela tangeritina pode sugerir uma abordagem terapêutica positiva na redução da carcinogênese e na melhora da resposta à quimioterapia, sendo necessários testes laboratoriais que comprovem essa hipótese.

A erosão é causada por contínuos desgastes e por sua exposição, tendo como fatores a chuva, topografia do terreno, infiltração de água, causando prejuízos ao solo e, consequentemente, ao produtor. É necessário que seja realizada a proteção do solo, podendo ser feita através de plantio direto, rotação de culturas, terraceamento e outras formas de manejo. Na cultura da cana-de-açúcar, o amendoim é utilizado para a realização da rotação de culturas, por possuir boa fixação biológica e auxiliar na cobertura do solo em períodos com maior índice de chuva. O presente trabalho teve como objetivo avaliar índices de perda de solo por erosão hídrica em diferentes tipos de alinhamento de plantio de Arachis hypogaea. O trabalho foi conduzido em Iturama – MG, em três áreas com diferentes tipos de alinhamento de plantio, sendo 90º, 45º e em nível em relação ao terraço e em cada área foi realizada a análise da declividade, velocidade de infiltração básica (VIB), da compactação do solo e perda de solo. As áreas tiveram comportamentos diferentes, onde a área de 90º apresentou maior taxa de variação de velocidade de infiltração e maior perda de solo, a área de 45º apresentou maior resistência a penetração e segunda maior perda de solo, enquanto a área em nível apresentou menor perda de solo e melhores índices de VIB e compactação. Conclui-se que o plantio em nível é recomendado para a obtenção de melhores resultados do manejo conservacionista, a fim de evitar e/ou diminuir a erosão hídrica.
 
SOIL LOSS THROUGH WATER EROSION IN DIFFERENT ALIGNMENT METHODS FOR PLANTING Arachis hypogaea
 
ABSTRACT
Erosion occurs due to continuous wear and tear, exposure to rain, topography, and water infiltration, leading to soil damage and consequently affecting the producer. It is essential to protect the soil, which means no-till farming, crop rotation, terracing, and other forms of management. In sugarcane cultivation, peanuts are used for crop rotation, as they have good biological fixation and help to cover the soil during periods of higher rainfall. This study aimed to estimate soil loss rates due to water erosion in different types of Arachis hypogaea planting alignments. The research was carried out in Iturama - MG, in three different areas with different types of planting alignment: 90º, 45º, and terrace level. The slope, basic infiltration rate (BIS), soil compaction, and soil loss were analyzed in each area. The areas behaved differently, with the 90º area showing the highest rate of change in infiltration speed and the most significant soil loss, the 45º area showing the highest resistance to penetration and the second most significant soil loss, while the level area showed a minor soil loss and the best BIS and compaction indices. It concludes that level planting is recommended to obtain better results from conservation management to avoid and/or reduce water erosion.

The grey mangrove population faces overexploitation, pollution, and global warming. Traditional propagation is challenging due to the recalcitrant seeds. The issues with Avicennia marina tissue culture are the browning of the explants and endophytes, which can affect the explants at any growing phase. This study aimed to produce and maintain A. marina explants until they developed into healthy plantlets. MS medium and WPM were used along with 0.4% PPM. Improving the survival, 400, 450, and 450 ppm PVP was also applied. The treatment using MS medium and WPM were compared, and the media enriched with 0.5 ppm BA and 1 ppm kinetin and no cytokinins were compared. The result showed that WPM+400 ppm PVP was better than MS medium (in any kind of treatment) in inducing shoots in A. marina (27%), as well as longer survival in in vitro conditions. In the MS media, all explants died after week 11, whereas in the WPM medium, three explants survived until week 16. In addition, most of the explants cultured in WPM exhibited no contamination until week 8, whereas in all treatments using MS media, there was contamination in the same week observed.
Cultura escrita y tecnocultura digital. Comunicación y educación
Authors: Ulloa Sanmiguel Alejandro
Published: December 2024

Esta obra plantea la hipótesis según la cual los estudiantes que ingresan a la universidad tienen una relación limitada e incipiente con la Cultura Escrita (CE) entendida como la articulación entre lectura, escritura y conocimiento. Si esa precaria relación se evidencia en sus modos de leer, escribir y conocer, ¿Cómo indagar sobre el fenómeno? ¿Y cómo enfrentarlo pedagógicamente? Al mismo tiempo tienen una relación intensa con la Tecnocultura Digital (TCD) desarrollada en torno a las TIC, que ha transformado las prácticas de lectura y escritura y los modos de conocer dentro y fuera del ciberespacio.

La CE y la TCD configuran dos modelos cognoscitivos presentes en la educación contemporánea, y aunque corren paralelos, no son necesariamente antagónicos. ¿Cómo investigar -y potenciar- ambos modelos en las prácticas pedagógicas para fortalecer la relación de los estudiantes con la Cultura Escrita, aprovechando la infraestructura de las plataformas digitales y los conocimientos ya consolidados de la Tecnocultura? La hipótesis está respaldada por la investigación etnográfica en el aula realizada por el autor. Además de un análisis crítico de las pruebas PISA y las pruebas Saber PRO, la indagación concluye en un diagnóstico en el que se especifican, se explican y se ilustran los problemas de lectura y escritura de los estudiantes. A partir de los conceptos de oralidad, escritura, enunciación, dinámica enunciativa, canon, polisemia, sentido literal, sentido figurado, comprensión textual, entre otros, se propone una alternativa pedagógica viable para profesores y estudiantes, utilizando la TCD para fortalecer la relación con la CE.
Teatro e identidad Una lectura más allá de la raza
Authors: Valencia Ramírez Jesús David
Published: December 2024

Este trabajo interroga el concepto de identidad a partir del análisis de seis obras de teatro afroestadounidense: Trouble in Mind de Alice Childress, Funnyhouse of a Negro de Adrienne Kennedy, The America Play de Suzan-Lori Parks, The Brothers Size de Tarell Alvin McCraney, for colored girls who have considered suicide/when the rainbow is enuf de Ntozake Shange y I Was Looking at he Ceiling and then I Saw the Sky de June Jordan.

En el análisis se movilizan dos conceptos que permiten comprender a la identidad como acción y al texto dramático como medio refractivo de experiencia: ipseidad y refracción estética. Respecto a cada obra se problematizan lecturas esencialistas de la identidad grupal y se revela cómo las interacciones de los personajes, en relación con la estructura de las obras y las perspectivas de los autores, se convierten en espacios de identidad personal.

El trabajo concluye con una discusión de las posibles aplicaciones de la ipseidad y la refracción estética más allá de la crítica dramática especializada.

The Cape Town Convention is a regulation that creates international standards for security interests (liens), leases, and various legal remedies for default in financing agreements, including repossession. Nevertheless, several incidents resulted in losses to the lessor because the Cape Town Convention was not implemented properly in Indonesia. This research aimed to analyze Indonesians’ compliance with implementing the deregistration and re-export of aircraft based on the Cape Town Convention. Apart from that, this research also examined the obstacles faced by the Indonesians when implementing the Cape Town Convention, especially in implementing Deregistration and Export (IDERA) in Indonesia, and whether they have solutions to overcome these obstacles. This research used a Normative-Empirical research methodology that analyzes the implementation of written legal provisions and whether the provisions of the statutory regulations have been implemented properly. This research employed qualitative methods to analyze the data collected. The conclusion is first, the Indonesian Government is implementing the deregistration and export of aircraft adequately based on the results of analysis by comparing the regulations and interviews with practitioners; second, the Indonesian Government in the process of implementing the Deregistration and Export Back of aircraft faces several obstacles, including the lack of legal certainty regarding the implementation mechanism and limited authority; and third, the Indonesian Government has a solution to overcome obstacles, including revising related regulations and becoming a mediator if there are problems as a form of legal filling. Therefore, it can provide certainty and peace of mind for lessors when receiving collateral in the form of aircraft in Indonesia. The results of this research are expected to increase understanding regarding deregistration and export back of aircraft based on the Cape Town Convention in Indonesia so that many parties understand and comprehend this matter.
