Published: July 2024

Considerando o potencial dos museus em geral e, em especial, dos museus de ciência, como espaços de educação ambiental, é importante discutir se as finalidades institucionais e as práticas educativas realizadas nesses espaços contemplam a dimensão da educação ambiental. Nesse sentido, o presente artigo tem o objetivo de caracterizar e analisar as finalidades institucionais e as práticas do Museu Florestal Octávio Vecchi e, a partir dessas análises, elaborar uma proposta de aspectos teóricos e práticos a serem considerados no desenvolvimento da educação ambiental no referido museu, localizado no Parque Estadual Alberto Löfgren, em São Paulo – SP. Foi realizada a análise documental das fontes primárias do acervo da Biblioteca do antigo Instituto Florestal e do acervo Museu Florestal Octávio Vecchi e realizada a observação de práticas educativas desenvolvidas no museu. Constatou-se que sempre houve uma preocupação com o patrimônio natural, em atividades com a comunidade local, no reforço na identidade local e como instituição. Nas visitas observadas foram identificadas práticas de educação ambiental nas suas macrotendências pragmática e conservacionista, enfatizando a preservação das florestas e a reciclagem. Destacou-se, pois, a importância de uma equipe fixa no serviço educativo, de maior integração entre as equipes de mediação do Museu Florestal e do parque no qual está inserido e de ampliação das parcerias para um trabalho de educação ambiental em uma perspectiva crítica.
Las dimensiones de los actos embrionarios de lectura. Conceptualización y propuesta de análisis en la obra de Hervé Tullet (1958-)
Authors: Selfa Sastre Moisés , Junqueira de Souza Renata
Published: July 2024

Este artículo conceptualiza las cuatro dimensiones de los actos embrionarios de lectura (dimensiones espaciotemporal, relacional, modal y objetual) en contextos de mediación lectora comprendidos entre los primeros meses de vida en niños y hasta los 4-5 años. A partir de un diseño de actividad especialmente creado para el trabajo de la lectura con prelectores, se analiza especialmente las dimensiones objetual (con lo que se lee y sobre lo que se lee) y modal (como se lee) en la obra del autor francés Hervé Tullet, un artista e ilustrador francés para prelectores, cuya obra resulta de interés para estos como se mostrará en este trabajo. Para el análisis de estas dos dimensiones, adoptamos una metodología basada en la lectura interpretativa de los títulos seleccionados de Tullet. Las conclusiones a las que llegamos demuestran que, sin necesidad de anticipar procesos de lectura que deben darse en etapas posteriores, la educación lectora y literaria en prelectores debe ser objeto especial de atención, en tanto que ayudan a construir las bases de lo que debe ser una buena aproximación a la lectura de textos de toda índole y en formatos diversificados.
"Up, una caja en captura": propuesta interactiva para fomentar aspectos lingüísticos y sociales en el alumnado
Authors: Antolinos Sánchez Alicia , Marco Martínez María
Published: July 2024

Desde el ámbito educativo, se conocen los beneficios que reportan los medios audiovisuales y digitales en la adquisición del conocimiento. Por ello, docentes de Educación Primaria crean e implementan propuestas educativas, digitales e interactivas asociadas al área de Lengua Castellana y Literatura, que no solo contemplan aspectos meramente curriculares sino también emocionales y sociales. Permitiendo ―además― la contribución de un desarrollo integral por parte de los discentes. A partir de ahí, el alumnado al que se ha implementado este proyecto pertenece al tercer nivel de Educación Primaria. Algunos de estos niños presentan necesidades específicas de apoyo educativo en el área de Audición y Lenguaje y dificultades en la adquisición de habilidades psicolingüísticas relacionadas con el habla. Por ello, la propuesta didáctica ayuda a descubrir, valorar y paliar situaciones de riesgo como pueden ser las dificultades de expresión, las alteraciones fonéticas y fonológicas, el aislamiento social, entre otros.
El hilo conductor de esta secuencia de actividades ha sido la película de Pixar Up: Una aventura de altura (2009), pues contiene valores donde los personajes reflejan la capacidad del ser humano para interactuar y resolver conflictos. De este modo, el propósito principal de la realización e implementación de este trabajo ―titulado Up, una caja en captura― ha sido el incremento del interés en el alumnado mediante retos lúdicos, que les han ayudado a comprender e interiorizar algunos de los saberes básicos de la asignatura. Así, se pretendía el logro de los objetivos propuestos no solo relacionados con la competencia en comunicación lingüística, sino también con las habilidades interpersonales e intrapersonales.

Authors: Orłowicz A. , Radoń M. , Lenik M. , Wnuk G.
Published: July 2024

This study addresses the issues related to the quality of the connection between cast iron liners and inserts in a pressure die-cast automotive engine block, along with the macro and micro wear of the cylinder bearing surface. it was found that the commonly used HPDC high-pressure casting technology of Al-Si alloy engine blocks with cast iron liners, in which the cylinder liner is then recreated, does not ensure their metallic connection. The micro-gap created there becomes thicker as the engine is used, which worsens the conditions for heat dissipation from the sleeve to the block. Locally, on the surface of the cylinder bearing surface, reductions in honing effects and longitudinal cracks were observed. The presented literature mechanism of micro wear of the cylinder bearing surface, dependent on the morphology of graphite segregations, was confirmed. The mechanism of creating micro-breaks in the area of phosphoric eutectic and graphite precipitation occurrence was presented, initiated by the formation of microcracks in the eutectic and delaminations at the eutectic-matrix boundary.

Authors: Shin Young-Chul , Ha Seong-Ho
Published: July 2024

In this study, microstructures of age-hardened 2014 Al alloy forged by cold biaxial alternate forging was investigated by transmission electron microscope. And also, the forming limits of age-hardened 2014 Al alloy were examined using both conventional compression test and biaxial alternate forging. As a result of compression test, it showed a perfect plastic behavior with no visible change in stress after 27% in strain and eventually, the curve fluctuated as a shear crack occurs after 51% strain. However, it was possible to impose very large strains on the 2014-T6 Al alloy workpieces through the biaxial alternate forging of up to 4 passes. The effective strain was possibly accumulated to 356% and 204% as the maximum and average values, respectively. The results of transmission electron microscope indicated that the high density dislocations were distributed after 3 passes. After 4 passes, the distribution of more increased dislocations was observed and band-shaped dislocation clustering appeared.

Authors: Nichul Unissa , Tambe Pankaj , Hiwarkar Vijay
Published: July 2024

The corrosion behaviour of a thermo-mechanically treated Beta C titanium alloy in a 3.5 wt% NaCl solution was investigated in this study. Thermomechanical processing prejudges titanium alloys to improve corrosion properties. Scanning electron microscopy and electron-backscattered diffractions were used to investigate the microstructural evolution and grain orientation after thermo-mechanical processing. The electrochemical characteristics of Beta C titanium alloy were examined using electrochemical impedance spectroscopy (EIS), corrosion potential, and corrosion current density measurements. The 45 percent deformed specimen experiences significant plastic deformation with increased dislocation density, resulting in strong ND //<111> orientation. However, the annealing after deformation exhibits a strong g-fiber texture with the lowest in-grain misorientation, which contributes to improving the corrosion resistance of the titanium alloy.

Published: July 2024

En el centro y sur de la república mexicana cada año los huracanes del mar Caribe y del océano Pacífico originan crecientes que definen una estación húmeda, y que en general aumentan en magnitud y peligrosidad conforme transcurre la temporada de ciclones. Ambas condiciones permiten el análisis de frecuencias bivariado de sus fechas de ocurrencia y sus gastos máximos (Qm). En este estudio, la distribución conjunta se formó con base en la función Cópula de Gumbel-Hougaard, que satisface la condición de dependencia ("λ" _U^CFG) observada y que combina como distribuciones marginales la de von Mises para las fechas de ocurrencia en el año y para los Qm una función probabilística idónea. La teoría expuesta se aplica a las crecientes anuales registradas en la estación de aforos Guamúchil de la Región Hidrológica No. 10 (Sinaloa), México, en el periodo de 1940 a 1971. La distribución de von Mises se ajusta vía optimización numérica con el algoritmo de Rosenbrock y la distribución idónea de los Qm fue la Kappa. Se formó la gráfica de periodos de retorno conjuntos de tipo AND de 50, 100 y 500 años. Además, se estimaron periodos de retorno conjuntos condicionales de fechas de ocurrencia, dado que el Qm tiene los periodos de retorno citados. Lo anterior permite estimaciones de la probabilidad de excedencia del Qm en lapsos definidos. Las conclusiones destacan la simplicidad de estos análisis de frecuencias bivariados por medio de las funciones Cópula y la importancia práctica de sus predicciones, según las fechas de ocurrencia.

La gestión del agua en el valle de la Sabana y sus cuencas aledañas en el área periurbana de la ciudad de Acapulco se ha realizado sin considerar las condiciones socioambientales que subyacen entre la pobreza, la marginación y su interacción con los recursos naturales, por lo que continúan persistiendo la construcción de riesgos por déficit en los servicios de agua potable y su saneamiento en un contexto de vulnerabilidad socioambiental de sus habitantes. El objetivo fue determinar los factores preponderantes que inciden en la vulnerabilidad socioambiental ante la falta de servicios de agua potable y saneamiento en la microcuenca Arroyo Las Cruces. Se aplicó el enfoque sistémico y de cuenca, así como la técnica multivariante análisis de correspondencias múltiples (ACM). Con base en el análisis relacional de los resultados del ACM, los factores que determinan la vulnerabilidad socioambiental son la carencia de servicios públicos, dependencia de la población por recursos naturales contaminados y baja participación comunitaria para hacer frente a sus problemas comunitarios ante la prevalencia de conflictos. La relación sistémica entre estos factores limita las capacidades socioorganizativas, lo que podría incidir en los procesos participativos para la gestión del agua bajo un esquema local de gobernanza que contribuya en asegurar el abastecimiento de agua y saneamiento en áreas marginales en este espacio periurbano.

Published: July 2024

Objective: This study investigates the complex relationship between environmental conservation and corruption, particularly focusing on how corrupt practices such as bribery undermine efforts to protect biodiversity, climate, and species survival in Malaysia. Despite the universal religious condemnation of corruption, it remains rampant, fueled by greed and often inadequately addressed by legal systems.
 
Method: Through an extensive literature review of journal articles, conference proceedings, books, and online sources, this paper illustrates specific cases where corruption has directly led to environmental degradation.
 
Research Findings and Discussions: The findings underscore the need for robust anti-corruption strategies that are informed by both environmental science and ethical considerations to effectively safeguard natural ecosystems.
Research Implications: This study can help everyone realize that every negative activity, no matter how minor, has a significant influence on the ecosystem, which needs to be protected.
 
Originality/Value: Public awareness of the perils of corruption and its consequences for the environment is raised by this research. This explains why it is against religious law to engage in corruption and the need for numerous reforms to end this corrupt behaviour.

Perbandingan Penegakan Aturan Lalu Lintas Antara Penerapan Tilang Manual Dan Electronic Traffic Law Enforcement (ETLE) Di Kota Padang
Authors: Dicaprio Leonardo , NOva Efren , Kurniawan Iwan
Published: July 2024

Enforcement of traffic rules is regulated in Law Number 22 of 2009 concerning Road Traffic and Transportation and Government Regulation No. 80 of 2012 concerning Procedures for Inspecting Motorized Vehicles on the Road and Enforcement of Traffic and Road Transportation Violations. The development of an electronic-based law enforcement system gave birth to Electronic Traffic Law Enforcement as an innovation to overcome obstacles in the application of manual fines. However, in its application, ETLE was also not free from various problems, so the urgency was born to conduct research to find out and compare the procedures for applying manual and ETLE tickets and how to apply future tickets in Indonesia, especially in the city of Padang as a research location. This study uses empirical juridical methods, the data used is primary data from interviews with Padang Police TMC operators and secondary data is in the form of document studies. The result of the research is that manual poles are directly imposed on violators by officers. Meanwhile, ETLE is a modern ticket system used by the police to monitor and prosecute traffic violations electronically with camera and sensor technology to identify vehicles that violate traffic rules, such as violating a red light or crossing the speed limit. Obstacles that occur in manual ticketing are low legal awareness from both law enforcers and the public. The obstacles that occur in ETLE are the limitations of static and mobile camera devices so that the application is not comprehensive. The application of fines in the future will still use a combination of manual and electronic ticketing due to the low level of public legal awareness and the uneven distribution of electronic ticketing devices in the city of Padang.

Published: July 2024

Public cemeteries are considered to be a potential source of groundwater pathogen contamination. Many settlements in Indonesia are located near cemeteries and rely on groundwater for consumption. However, there is no information available on whether the simple method of boiling can improve the microbiological quality of groundwater around cemeteries. Therefore, this experimental study aimed to determine the effectiveness of boiling in improving the microbiological quality of groundwater around Bonoloyo Cemetery. The study had two treatments: groundwater without boiling (control) and groundwater that had been boiled. Samples were collected from two points (S1 and S2) inside the cemetery and three points (S3, S4, and S5) outside the cemetery. The microbiological quality of groundwater was analyzed using the MPN method for each treatment. Samples that produced gas in positive tubes were inoculated on eosin methylene blue (EMB) media. The results of the study showed that S1, S2, S3, and S5 had total coliform levels that exceeded the normal threshold for water. Fecal coliform was found in S3 and S5. However, after boiling, there was an average decrease in total coliforms in samples S1, S3, S4, and S5. There was also no growth of E. coli in samples S3 and S5. The decrease in MPN values ​​in the samples indicates that boiling can improve the microbiological quality of groundwater at cemetery Bonoloyo Surakarta.

Published: July 2024

Practicum worksheets are a tool used by students to increase their understanding of various biological concepts through experiments and direct observation. However, there are many biology practicum worksheets used today often do not meet the appropriate standards. Therefore, this research aims to analyze conceptual, procedural, and knowledge construction aspects based on vee diagrams on students' practicum worksheets. The method used in this research is qualitative-descriptive. The samples were selected using purposive sampling so that six samples of practicum worksheets for phase F students in the Merdeka Curriculum were obtained with material testing carbohydrates in food. The research results show that conceptually, the practicum content is not in accordance with the learning outcomes in the Merdeka Curriculum. Procedurally, the practicum worksheets still need to be improved in terms of tools, materials, procedures, phenomenon objects, and data recording. This has an impact on students' difficulties in constructing their knowledge. It is hoped that the results of the reconstruction of practicum worksheets based on conceptual, procedural, and knowledge construction analysis can be used as a reference and basis for teachers in designing practicum activities specifically on digestive system material.

Published: July 2024

Background:

Peritoneal dialysis (PD) is an important modality of renal replacement therapy (RRT). Peritonitis and ultrafiltration failure are complications that have a long-term impact on PD patients. Besides touch contamination, procedural errors and clinical reasons of peritonitis, contaminants, and constituents of peritoneal dialysis fluids (PDFs) have been implicated in causing peritonitis and ultrafiltration failure. This study was aimed to test the PDFs in India for the presence of migratory plastics.

Materials and Methods:

PDFs from the two manufacturers in India were tested using liquid chromatography mass spectrometry (LCMS) and gas chromatography mass spectrometry (GCMS) with headspace analysis (volatile compounds) and pyrolysis of plastics (polymer compounds). The storage conditions and handling were uniform.

Results:

The results revealed impurities of acetate compounds and aldehyde derivatives of glucose degradation products (GDPs) with contaminants and leachable plastics. There were high levels of GDP derivative in the form of 5-hydroxymethylfurfural compounds (5-HMF). The analysis revealed the presence of plastic softeners in very high concentrations.

Conclusion:

The study unmasks the presence of chemicals and GDPs that can be implicated in pathogenesis of sterile peritonitis and ultrafiltration failure. The study demonstrated the presence of leachable plastics. In conclusion, LCMS and GCMS studies can be used to test PDFs for unwanted chemicals prior to human use.

We present an optical study based on the Quasiparticle Self-Consistent GW (QSGW) approximation, combining structural information taken from density-functional theory (DFT) to elucidate spectral features of CO adsorbed on Pt (111) and Cu (111). Optical information and structural arrangement of the adsorbed CO are correlated by varying both site positions and CO coverage as compared to experimental studies (θ = ¼ to θ = ½). This enables us to resolve key spectral features of both occupied and unoccupied molecular states at various adsorbate coverages, comparing theory to experiment. Using experimental data as benchmarks: we show the theory compares well with available data. Its predictive power provides a new path to infer information about the structure of CO from optical information, and can help to predict the presence of other little understood adsorbates such as an OCCO dimer, that may be relevant to mechanistic pathways for reduction of CO2 to high value C2+ products. This new approach complements total energy calculations, and also fills a void in DFT based theory that is known to be an unreliable predictor of the energetics of CO on transition metal surfaces.

Alzheimer's Disease (AD), reported for the first time in 1906, is a common disease that remains incurable to this day. In the past, a family of treatments using Cu(II) chelators failed during clinical trials, evidencing the importance of pre-clinical studies. In this work, we performed a complete characterisation of TDMQ20, a new potential drug against AD, using electrochemistry and spectroelectrochemistry. On the basis of voltammetry, we determined that TDMQ20 undergoes a two-step irreversible oxidation process and a one-step irreversible reduction process. Both oxidation and reduction reactions are pH-sensitive. Bidimensional UV-Vis spectroelectrochemistry (UV-Vis-SEC) allowed us to confirm that oxidation of TDMQ20 can occur both on the aliphatic chain and on the aromatic ring. The results expand the knowledge of the TDMQ20 redox activity in the human body which is important from the point of view of the toxicity of the proposed therapy.

The computational cost of accurate quantum chemistry (QC) calculations of large molecular systems can often be unbearably high. Machine learning offers a lower computational cost compared to QC methods while maintaining their accuracy. In this study, we employ the polarizable atom interaction neural network (PaiNN) architecture to train and model the potential energy surface of molecular clusters relevant to atmospheric new particle formation, such as sulfuric acid–ammonia clusters. We compare the differences between the neural network and previous kernel ridge regression modeling for the Clusteromics I–V data sets. We showcase three models capable of predicting electronic binding energies and interatomic forces with mean absolute errors of <0.3 kcal/mol and <0.2 kcal/mol/ ̊A, respectively. Furthermore, we demonstrate that the error of the modeled properties remains below the chemical accuracy of 1 kcal/mol even for clusters vastly larger than those in the training database (up to (H2SO4)15(NH3)15 clusters, containing 30 molecules). Consequently, we emphasize the potential applications of these models for faster and more thorough configurational sampling and for boosting molecular dynamics studies of large atmospheric molecular clusters.

This study is conducted to build an assessment scale on stakeholders' readiness level to apply blockchain technology to the agricultural supply chain. By referencing the theoretical model of Technology - Organization - Environment (TOE) combined with the qualitative research step, the study proposed a new scale with 65 observed items and 18 factors. Next, the study carries out a quantitative research step based on the case of the pork supply chain in Hue. The sample consists of 365 individual/organizational stakeholders. The analysis results shortened the proposed scale to 62 observed items, 18 factors, and 4 second-order factors – including readiness on technological conditions (TEC), readiness on inter-organizational conditions (INTER), readiness on intra-organizational conditions (INTRA), and readiness on environmental conditions (ENV). Further analyzing the importance of the factors, the results reveal that relative advantage (RA), trust (TRU), trading partner pressure (TPP), firm size (FS), top management support (TMS), and competitive pressure (CP) are considered the essential foundations for the adoption of blockchain technology to the agricultural supply chain.
