Published: June 2024

Na Caatinga a exploração de recursos naturais realizada de forma indiscriminada provoca danos dificilmente remediáveis no âmbito ambiental, social e econômico. Nessa perspectiva, esta pesquisa analisou a percepção ambiental sobre os recursos florestais da caatinga em diferentes comunidades rurais. O estudo foi realizado com moradores das comunidades de Aroeira e Santana, ambas localizadas no município de Olivedos – Paraíba. Trata-se de um estudo etnobiológico/etnobotânico, de abordagem metodológica qualitativa e quantitativa. Foram entrevistados 65 informantes (53 moradores da Comunidade de Aroeiras) e (12 moradores da Comunidade de Santana), entre homens e mulheres, responsáveis pelas residências. A entrevista semiestruturada, ocorreu no período de maio a agosto de 2022. As informações foram enriquecidas e confirmadas com a utilização de outras técnicas de investigação como a observação participativa e a turnê guiada. Os dados obtidos foram transcritos, posteriormente categorizados e tabulados em planilha Excel. Como resultado constatou-se que os participantes identificam e/ou usam mais de 80 espécies de plantas distribuídas em sete categorias das quais destacam-se alimentação humana, medicinal e madeira (para combustível e construção). Em relação à percepção positiva, os entrevistados percebem a Caatinga como bioma, beleza, bem-estar, diversidade, mata fechada, resiliência, riqueza e vegetação, já as indicações negativas foram seca, sofrimento e escassez. Essa dicotomia reflete a realidade do ambiente, demonstrando que viver na região da caatinga lhes confere, para além das dificuldades, qualidade de vida pelo tipo de vegetação, beleza e diversidade de espécies úteis. Discute-se a importância dos recursos florestais, como estes são utilizados e a implicação para a conservação da Caatinga.

Modelagem numérica de placas de concreto simples: implicações para o dimensionamento à fadiga de pavimentos rígidos
Authors: Pinto Estevão Mendonça , Ávila Fábio Grisolia de , Nascimento Filipe Almeida Corrêa do
Published: June 2024

O transporte rodoviário de cargas é uma prática expressiva no Brasil, exigindo uma análise aprofundada do comportamento das placas de concreto em pavimentos rígidos devido à sua alta capacidade de suportar cargas. No entanto, essa perspectiva carece de normas e métodos de dimensionamento mais sofisticados, que permitam uma análise detalhada do comportamento estrutural da placa e otimização do projeto, principalmente quanto à fadiga, que não é propriamente tratada nos métodos tradicionais, tendendo a superdimensionar o pavimento. A pesquisa realizada tem como objetivo verificar a resposta e resistência dessas placas utilizando a análise numérica como uma ferramenta e avaliando o desempenho em termos de fadiga em diferentes condições de carga. Um estudo de caso aplicou métodos empíricos tradicionais no dimensionamento de pavimentos rígidos (PCA 1966, PCA 1984, Guia AASHTO 1993 e 1998) comparando-os com a análise numérica. Os resultados indicaram a tendência dos métodos empíricos em superestimar a espessura da placa em média 47%, enquanto a análise numérica tende a oferecer maior precisão quando o critério de dimensionamento utilizado é a resistência à fadiga. A análise numérica é uma ferramenta sofisticada que parece conduzir a um dimensionamento preciso e otimizado, podendo reduzir custos e garantir um desempenho estrutural adequado. A representação da interação entre as placas de concreto e o subleito apresenta desafios, já que as condições do solo podem variar significativamente com o tempo e as condições climáticas, influenciando a resposta do pavimento. Essas limitações, somadas a outros efeitos não contemplados no presente estudo, como a erosão, exigem cautela ao interpretar os resultados da modelagem numérica.

Chemistry teaching requires the use of approaches that provide students with conditions so that they can critically interpret the reality in which they live. This implies the need to link the content worked with the social context in which the student is inserted. However, the practice of contextualizing is rarely addressed in the classroom, especially when it comes to teaching Organic Chemistry. Therefore, this research aimed to propose a didactic intervention based on the theme of medicinal plants as a proposal to integrate the student's daily life with the construction of knowledge about Organic Functions, in order to make the teaching and learning process more meaningful in accordance with the proposal for Scientific Literacy. The research was carried out with students from a 3rd year class of Integrated Technical High School in Computer Science for the Internet at the Federal Institute of Education Science and Technology Baiano - Campus Guanambi, in the period between November 2022 and May 2023 and involved six stages, with diverse activities. The use of the theme met the objectives of the study proposal, as, depending on the receptivity of the participants, it constitutes a teaching resource that brought the study of Organic Functions closer to everyday life, favoring more meaningful learning. The proposed use of the generating theme also demonstrated that it aroused the students' curiosity and interest, given their active participation in the construction of knowledge, which may have contributed to the teaching and scientific literacy processes.

Published: June 2024

As vigas são importantes elementos estruturais sujeitos ao comportamento de flexão devido a carregamentos transversais, sendo representadas pelos modelos matemáticos de Euler-Bernoulli e Timoshenko. As aproximações em diferenças finitas, usadas para discretizar os modelos, são construídas normalmente sobre grid de pontos regulares (ou uniformes), os quais limitam a aplicação do método a condições de apoio e carregamentos específicos. No presente estudo, são desenvolvidas aproximações de diferenças finitas para grid de pontos irregulares (ou não uniformes) para ambos os modelos de viga, considerando a avaliação da taxa de convergência, a análise da influência da esbeltez na acurácia dos resultados, bem como o uso de adaptabilidade da malha de pontos às regiões de maior interesse. Os resultados demonstram que o uso de grids não uniformes não interferem na taxa de convergência da discretização, porém são fundamentais para generalizar o método de diferenças finitas para condições de apoio e carregamentos quaisquer. As aproximações em diferenças finitas para a viga de Timoshenko permitem usar o modelo para vigas curtas e esbeltas. Tais resultados mostram que o método de diferenças finitas pode ser usado, sem restrições, para a discretização de elementos de barra, facilitando a introdução de estudantes de graduação e pós-graduação em modelagem computacional.

Published: June 2024

A simulation model has been made for molten corium in a nuclear reactor using the Moving Particle Semi-Implicit (MPS) method. By setting the value of dynamic viscosity and temperature of corium, simulations are carried out to display the pressure profile and flow velocity of the corium fluid that falls from the RPV to the plenum. In the first simulation to observe the pressure and velocity profile of the corium in the plenum, three conditions were made: the plenum was empty; the plenum was filled with corium fluid, and the plenum was filled with debris. The second simulation was carried out to determine the relationship between the time required for corium to reach the plenum for variations in corium viscosity and temperature values. The simulation results show that the increase in corium viscosity will be proportional to the length of time it takes to reach the plenum. In contrast to the effect of temperature where the increase in corium temperature will be the smaller the time required.

Frequency-Histogram Coarse Graining in Elementary and 2-Dimensional Cellular Automata
Authors: Sanyam Jain  , Stefano Nichele
Published: June 2024

Cellular automata and other discrete dynamical systems have long been studied as models of emergent complexity. Recently, neural cellular automata have been proposed as models to investigate the emerge of a more general artificial intelligence, thanks to their propensity to support properties such as self-organization, emergence, and open-endedness. However, understanding emergent complexity in large scale systems is an open challenge. How can the important computations leading to emergent complex structures and behaviors be identified? In this work, we systematically investigate a form of dimensionality reduction for 1-dimensional and 2-dimensional cellular automata based on coarse-graining of macrostates into smaller blocks. We discuss selected examples and provide the entire exploration of coarse graining with different filtering levels in the appendix (available also digitally at this link: https://s4nyam.github.io/eca88/. We argue that being able to capture emergent complexity in AI systems may pave the way to open-ended evolution, a plausible path to reach artificial general intelligence.

Authors: Abass Farroq A. , Al-Khekany Alaa M.
Published: June 2024

The research examines the behavior and reactions of six double-web steel sections of non-composite and composite-reinforced concrete deck slabs and castellated steel beams. The composite beams with concrete slabs and non-composite steel beams with different levels of castellation were isolated from the specimens at 0 %, 25 %, and 50 %. The ultimate strength, load at cracking, failure mechanism, load/deflection relationship at midspan, stiffness, and ductility were evaluated. The concrete slab increased the ultimate load by 61,1 %, 63,3 %, and 55,5 % for castellation ratios of 0 %, 25 %, and 50 %, respectively. The non-composite and composite castellated beams' shear strength decreased as the expansion ratio increased. The angle twist of non-composite samples was greater than that of composite samples due to their greater ductility and lower stiffness. The concrete slab also restricted the samples and reduced their rotation

Authors: Sabah Falieh Noor , Najeeb Shehab Saad
Published: June 2024

Porous materials are used in engineering and industry due to their heat transmission qualities. This study examined forced convection flow through an annular tube packed with sphere balls of various materials and sizes using numerical analysis. The sphere balls were permeable. Ceramic, plastic, and steel with spherical diameters of 3, 5, and 6 and porosity of 0.4 were tested for heat dissipated and fluid flow. Also, test the impact of steel balls of diameter 6mm with 0.6 and 0.8 porosity. The numerical simulation results are used to analyze the forced convection and fluid flow parameters of a three-dimensional annular tube with continuous heat flux in the Reynold number range (5000-14000). Steel balls had an 80% higher heat transfer coefficient than annular tubes without porous mediums. The simulation showed that inserting the porous media increased annular tube pressure loss. The maximum heat transfer coefficient improved by about 80% when the spherical diameter is 3 mm. Also, the result illustrated the heat transfer coefficient of steel balls Increased by about 79%, 69%, and 49%, with 0.4, 0.6, and 0.8 respectively

Authors: Hussein Marwan B. , Mustafa Ali M. , Abdulkareem Makarim H.
Published: June 2024

This work evaluates experimentally the corrosion and tip testing of Ti-13Zr-13Nb joint implant alloys and commercially pure titanium (cp-Ti) covered with YSZ nanoceramic. Through the use of the Taguchi design of experiments (DOE) approach, the dip coating process produced a thin sticky covering. The effects of temperature, YSZ concentration, duration, and the level of Ti alloy substrate grinding during dip coating were investigated using a L9-type orthogonal Taguchi array to determine the deposition yield. The thickness and adhesion tests that were utilized to optimize the dip coating conditions served as the input data, and the Ti alloys were coated using the ideal dip coating technique parameters as previously mentioned. For commercial Ti, the ideal values for YSZ coating thickness and adhesion were 60°C, 10 seconds, 10 % concentration, and 250 degrees of grinding; correspondingly, for Ti-13Zr-13Nb, the ideal values were 60°C, 10 seconds, 15 % concentration, and 400 degrees of grinding. For both Cp-Ti and Ti-13Zr-13Nb, the obtained thickness and removal area (adhesion) were 58,5 µm and 11,45 %, respectively, and 69,5µm and 9,33 %, respectively. High-resolution scanning electron microscopy (FE-SEM) images were used to study the coated alloys; optical microscopy and AFM were used to identify the microstructure and thickness measurements of the coated surfaces; EDAX was used to analyze the coating composition; and XRD was used to analyze the formed phases. The optimized coated Ti alloys' corrosion resistance was investigated in simulated body fluid (SBF) using electrochemical methods such as cyclic polarization and Tafel polarization, and the adhesion strength of the coatings was measured using a tip tester. The following corrosion-resistant values were used to compare Ti-13Zr-13Nb and coated Cp-Ti: In Ringer's solution at 37°C, both coating alloys—Cp-Ti and Ti-13Zr-13Nb—improved corrosion resistance; however, the coated Ti-13Zr-13Nb alloy demonstrated greater corrosion resistance than the coated Cp-Ti alloy (5,417×10-3 and 1,042×10-2, respectively)

Published: June 2024

This research investigates the corrosion inhibition capabilities of BCAA-derived inhibitors for low-carbon steels and dead mild carbon steels with distinct carbon contents when exposed to a 1M HCL solution. The effectiveness of the inhibitors was evaluated by measurements of weight loss and polarization. The study revealed that at a concentration of 10 grams, the weighing method showed that the BCAA inhibitor showed protection effectiveness (87 percent) at 313 K for low carbon steel and (89 percent) effectiveness at 303 K for dead carbon steel. Using a concentration of 15 g, the polarization method showed inhibitory activity of (96 percent) at 313 K for low-carbon steel and (96 percent) at 303 K for dead light carbon steel. These results indicate that the inhibition efficiency is affected by the carbon content. Samples were subjected to scanning electron microscopy (SEM) and optical microscope analysis before and after adding the inhibitor. When examined using FTIR spectroscopy, BCAA showed significant efficiency as a corrosion inhibitor for steel alloys immersed in acidic conditions

Reusing and recycling waste are efficient ways to reduce waste production while dealing with associated environmental issues. The applications still have a lot of opportunity for improvement, though. This academic article discusses recycled glass and eggshell waste used in construction. The impact of these wastes on specific mechanical characteristics was examined. These wastes have been used as powder and partially substituted for cement in concrete. From the results, it was found that utilizing 10 % glass powder (G) with 5 % eggshell powder (E) gave the highest compressive strength by about 16,37 %, 9,63 %, and 10,85 % at 7, 28, and 56 days, respectively compared to the control specimen.  For the same mix, UPV increased by about 14,28 %, 6,66 %, and 6,8 % at 7, 28, and 56 days, respectively compared to the control specimens.  The mix contains 10 % G with 15 % E powders impacted negatively on properties of concrete. The tensile strengths increased similarly to the compressive strengths, as they increased at 5 % E and began to gradually decrease when the compensation ratio was increased. Utilizing G and E wastes in concrete has been evaluated using an ANOVA statistical study. Analysis reveals that these wastes had a substantial impact on the strength and other variations of concrete properties, and the optimal E to be used with 10 % G is 5 %

Multimediaalisuus ikkunana työelämän digitalisaatioon
Authors: Lehtinen Esa

Digitalization has had a profound effect on work practices. However, digital practices have not replaced older practices such as paper documents and face-to-face interactions. Rather, interaction in the workplace is multimedial: different forms of communication are intertwined with each other. In this article, drawing form interaction studies, I describe the effects of multimediality for workplace practices in two ways: how multimediality explains the often unconventional ways digital tools are used in workplaces, and how complex, longitudinal workplace processes are organized through multimedial practices. In the concluding section, I also discuss multimedial competences needed in the 21st century workplace.

The realization of scientific research that allows an approach to the characterization of the integral development of children with Down syndrome has been a priority in the pedagogical field, given its impact on educational care. Particularly, the characterization of language development in these children, in spite of having a special significance, maintains insufficiencies that limit the realization of didactic actions by teachers and specialists who have an impact on them. The objective of this article was to characterize the development of language in children with Down syndrome between 3 and 6 years of age as a premise for an adequate early attention to this area. The results presented here constitute the initial phase of a more in-depth study validated in practice. Given the complexity and diversity of the data obtained, it was necessary to resort to various instruments that respond to qualitative research, specifically elaborated for the specific scenario under investigation, such as: unstructured interview, participant observation, document analysis. Triangulation of sources was also used to demonstrate convergence between the results obtained. The cross-checking of information and the use of theoretical methods allowed identifying that there are distinctive characteristics in the language development of children with Down syndrome between 3 and 6 years of age, and that it is necessary to have a detailed characterization of the language achievements, so that it can contribute to improve the early care process offered to them.

Background: Tomosynthesis, despite its potential to produce superior images compared to mammography for Breast Imaging-Reporting and Data System (BI-RADS) scoring, has not yet been widely adopted. This is likely due to a combination of insufficient data and a scarcity of expertise in this area. Objectives: In this study, we aimed to evaluate the potential benefits of tomosynthesis for patients with indeterminate BI-RADS results from full-field digital mammography (FFDM). Specifically, we sought to determine whether this method could clarify ambiguous BI-RADS scores. Patients and Methods: This cross-sectional study involved 386 female patients, with an average age of 44.7 ± 7.9 years. The study included all patients who were admitted to a referral center for breast radiology during 2019 - 2020 and underwent both FFDM and tomosynthesis within a short interval. The purpose of performing tomosynthesis was to assess its additional benefits over FFDM. The collected data was input into SPSS version 20 for analysis. A P-value of less than 0.05 was deemed statistically significant. Results: Out of 152 patients who initially had indeterminate findings in mammography (BI-RADS score of 0), only one patient (0.7%) remained indeterminate after tomosynthesis. This implies that tomosynthesis was able to clarify the BI-RADS scores for 99.3% of patients with previously indeterminate scores. Specifically, out of these 151 patients, 81 were scored as BI-RADS 2, 45 as BI-RADS 3, 19 as BI-RADS 4, and six as BI-RADS 5. Conclusion: Tomosynthesis has the capability to clarify unclear FFDM BI-RADS scores in over 99% of cases. This suggests that it could serve as the primary supplementary imaging technique for cases with indeterminate BI-RADS scores.

Background: Due to the unique properties of Astragalus in treating diseases and strengthening the immune system, this study aimed to investigate, for the first time, the immune modulation and apoptosis induction by Astragalus ecbatanus extract against Leishmania tropica. Methods: The study assessed the in vitro efficacy of the Astragalus ecbatanus extract against both the promastigote and amastigote stages of L. tropica (MHOM/AF/88/KK27). Additionally, the effects of the extract on inducing nitric oxide (NO) release and its cytotoxicity on human macrophage cells were determined by calculating the 50% cytotoxic concentrations (CC50). The study also evaluated the Caspase-3-like activity in extract-treated parasites and conducted quantitative real-time PCR to assess the expression of genes associated with T lymphocytes. Results: Our study demonstrated that the A. ecbatanus extract significantly (P < 0.001) decreased the viability of both L. tropica promastigote and amastigote forms compared to the negative control. Moreover, the extract exhibited a high selectivity index (> 10), indicating its strong specificity towards intracellular parasites while showing low cytotoxicity to host cells. Our results indicated a dose-dependent upregulation of the expression levels of genes for inducible nitric oxide synthase (iNOS), interferon-gamma (IFN-γ), tumor necrosis factor-alpha (TNFα), and interleukin-10 (IL-10) in macrophages after exposure to A. ecbatanus ethyl acetate extract (P < 0.01). In contrast, the gene expression level of IL-10 exhibited a dose-dependent downregulation after exposure to A. ecbatanus ethyl acetate extract. We also found that the THP-1 macrophages exposed to the A. ecbatanus ethyl acetate extract exhibited enhanced production of nitric oxide (P < 0.001). Additionally, the ethyl acetate extract of A. ecbatanus significantly enhanced caspase-3 activation in Leishmania parasites (P < 0.01). Conclusions: The results demonstrated the significant impact of A. ecbatanus ethyl acetate extract on inhibiting and eradicating Leishmania parasites in laboratory settings. While some cellular mechanisms of action were identified, such as immune modulation and apoptosis induction against Leishmania parasites, further investigation is essential to elucidate the specific mechanisms of action and assess the efficacy in animal and human populations.
