Development of artificial aggregates by using sodium silicate activated copper tailings and slag
type: item
description: This study investigated the development of artificial aggregates using copper tailings activated by sodium silicate via granulation. Five different mixes were prepared by incorporating varying amounts of ground granulated blast furnace slag (GGBS) and sodium silicate. The granulation process was performed in a rotating disk granulator, with water sprayed onto the dry mixture to facilitate binding. The resulting aggregates, ranging from 5 to 25 mm in diameter, were cured in a humid environment for 3, 7, and 28 d. The aggregates were then tested for size distribution, oven-dried density, water absorption, crushing strength, and individual-granule strength. Microstructural analysis was conducted using scanning electron microscopy (SEM) and X-ray computed tomography (XCT). The results showed that the addition of GGBS significantly improved the properties of the artificial aggregates, resulting in a higher density, lower water absorption, and increased strength.XCT images revealed a more refined pore structure with smaller and more evenly distributed pores in the GGBS-containing samples. The crushing strength and individual granule strength followed a Weibull distribution, with the GGBS samples exhibiting higher strength values. SEM analysis confirmed the formation of N-A-S-H gel in the GGBS samples, which acted as a binding phase and improved the microstructure. These findings demonstrate the potential of using copper tailings and GGBS to produce sustainable artificial aggregates with enhanced properties for construction applications.

Mentorship and Engineering Excellence: Fostering A Culture of Innovation
type: item
description: In the contemporary engineering landscape, mentorship has emerged as a pivotal enabler of innovation, technical excellence, and leadership development. This article develops a theoretical lens for understanding the dynamic interplay between structured mentorship and innovation outcomes in engineering contexts. Building on multidisciplinary theories from organizational behavior, social learning, and systems thinking, it proposes the Mentorship-Driven Innovation Framework (MDIF). The framework conceptualizes mentorship as a system of inputs, mediating mechanisms, and feedback loops moderated by organizational culture and context. Through historical analysis, empirical synthesis, and conceptual modeling, the paper highlights how mentorship facilitates knowledge transfer, identity formation, psychological safety, and collaborative creativity. Despite its promise, limitations such as measurement complexity, cultural variability, and underrepresentation of informal mentorship are acknowledged. Future research directions are proposed to refine theory and expand its empirical base. This study offers critical insights for educators, engineering managers, and policymakers aiming to cultivate sustainable innovation cultures in technical organizations.

Effects of Burning on Chemical Attributes And Soil Organic Matter In Cerrado Areas
type: item
description: The practice of burning for soil management is common due to its low cost and simplicity, allowing immediate soil reuse. Despite its benefits, such as stimulating pasture regrowth and pest control, there are negative effects, such as soil degradation and reduced productivity in the long term. The technique is controversial, balancing tradition and sustainability, requiring effective alternatives without compromising environmental health. Research indicates both improvements in fertility and damage to soil properties, indicating the need for responsible use. This study evaluated the immediate effect of fire on the chemical attributes of pasture soil, comparing it with a soil of adjacent native vegetation. Conducted at Chácara Vitória, in Monte do Carmo - TO, the experiment Cerrado. analyzed two areas: one of virgin cerrado and another of pasture that had been burned annually for over twenty years. Laboratory analysis showed an increase in K, S, Mn, Zn, P-meh, Mg, Fe, Cu and Ca, and a decrease in Al, B, H+Al. The reviewed literature presents diverse results due to several variables. It is concluded that burning significantly impacts the chemical composition of the soil and should be carefully evaluated considering its long-term implications.

Diffraction Model on the Breakwater Gap Based on Velocity Potential Equation
type: item
description: In this research, the governing equation for wave diffraction at a breakwater gap is formulated. The equation is derived by substituting the three-dimensional velocity potential—obtained as the solution to the Laplace equation—into the Laplace equation, under the condition that there is a variation or differential in the wave constants. The resulting equation is a second-order partial differential equation with respect to one of the wave constants. The governing equation is then solved numerically using the Finite Difference Method, employing the Successive Over Relaxation (SOR) technique for the iterative calculation.

A Comparative Analysis of Logistic Regression and Random Forest for Individual Fairness in Machine Learning
type: item
description: In high-stakes domains such as finance, healthcare, and criminal justice, machine learning (ML) systems must balance predictive performance with fairness and transparency. This paper presents a comparative analysis of two widely used ML models, logistic regression and random forest, evaluated through the lens of individual fairness. Using the UCI Adult Income and COMPAS datasets, we assess performance in terms of accuracy, F1 score, individual consistency, and disparate treatment. Our findings indicate that while random forests offer marginally higher accuracy (by approximately 1%), logistic regression improves individual consistency by up to 4%, suggesting it is preferable in fairness-sensitive applications. This study emphasizes model selection’s role in achieving ethically responsible AI.

type: item
description: Listed companies are vital to capital markets, but issues like information opacity and poor governance elevate credit risks, impacting economic stability. This study proposes a Long Short-Term Memory (LSTM) neural network model to assess credit risk by analyzing time-series financial indicators. Factor analysis reduces dimensionality of indicators, followed by LSTM training on sequential data to predict risk levels. Using CSI 300 firms’ data, the model achieves 87.5% accuracy, outperforming traditional methods like logistic regression (80.2%). The approach captures temporal dependencies, offering dynamic risk forecasts. Limitations include data quality reliance and computational complexity. Results support regulators and investors in enhancing risk management.

DreamTalk-DMT: A Lightweight Sparse Mechanism Model with Dynamic Thresholds
type: item
description: Aiming at the shortcomings of the DreamTalk 2D digital human synthesis model in computational efficiency and expression generation fineness, this paper proposes an optimization method combining adaptive sparsity and cross-modal feature enhancement. By introducing a dynamic threshold sparsity mechanism into the diffusion model, the sparsity ratio was dynamically adjusted based on the learnable threshold and Exponential Moving Average (EMA), and the Mutual information Constraint (MI Constraint) was combined to minimize the information loss, which reduced the calculation amount of the model while retaining key features. The model architecture is improved, and the decoupled decoder is designed to decompose the facial expression into the upper and lower regions for independent processing. The dynamic linear layer is combined to realize parameter adaptation under the style condition, and the detail expression of expression generation is improved. In addition, Tacotron speech features and Wav2Vec acoustic features are fused to enhance the synchronization of speech and expression, and skip connections are used to optimize the information transmission efficiency.

Determination of the Rigor Mortis Index for the species Eugerres brasilianus (Cuvier, 1830), Captured in Itaipava, Espírito Santo - Brasil
type: item
description: Fish has increasingly become an essential element in the search for sustainable protein sources in human nutrition. The diverse species available along the 8,000 km of our country's coastline provide a rich and varied source of food. To consolidate the fishing market, ensuring the quality of the food presented to the consumer is crucial. Among the existing ways to ensure the freshness of fish, the rigor mortis index reflects the biochemical aspects of the flesh and the stages it undergoes until it becomes unfit for human consumption. This study aimed to determine the rigor mortis index and its stages in the Carapeba species (E. brasilianus). The samples were captured on the beach of Itaipava, Espírito Santo, Brazil, and the experiment was conducted at IFES – Piúma Campus over a period of 30 hours. The measurements taken indicate that Carapeba exhibits pronounced and long-lasting rigor mortis indices, suggesting great potential in terms of quality and freshness. Specimens P2 and P3 reached the rigor mortis stage first, both at around 4.3 hours, while P1 took 5.3 hours. The full rigor mortis stage lasted 40 minutes for P1, whereas P2 and P3 remained in full rigor for 18.7 and 16.7 hours, respectively. The importance of this study for the species is notable, as even under stressful slaughter methods, the rigor mortis response time is significantly high, indicating an extremely attractive preservation potential.

Coastline Response to Groins Analysis
type: item
description: This research investigates the morphological response of coastlines to the construction of groins, focusing on both single groins and paired groins. The evolution of the coastline is analyzed with the aim of identifying a new stable coastline geometry. The approach involves modeling the stable coastline using polynomial functions, where the polynomial coefficients are determined through the application of point-specific and line-specific characteristics, as well as the principle of mass conservation. The resulting stable coastline configuration typically forms a crenulate-shaped bay an equilibrium shoreline geometry occurring between two headlands. The derived geometry, whether partial or complete, exhibits features consistent with the known characteristics and dimensions of a crenulate-shaped bay.The modeled stable coastline can be calibrated against empirical crenulate bay profiles, confirming its validity as a representation of an actual stable coastal form.

Simultaneous determination of Copper, Zinc and Nikel in Electroplating Waste water by UV-VIS Spectroscopy Combined with advanced Machine Learning and Deep Learning Models
type: item
description: Monitoring to evaluate wastewater quality during the production process requires simple measurements and Realtime analysis as well. Among common methods for heavy metal analysis, the UV-VIS absorption spectroscopy is considered a potential analytical method due to its low cost and simple operation, direct online integration with treatment tanks. However, it faces limitations in simultaneously analyzing multiple metals due to overlapping absorption spectra. This study applied machine learning (ML) algorithms (Decision Tree (DT), Random Forest(RF) and deep learning (DL) models (Multilayer Perceptron - MLP, and 1D Convolutional Neural Network - 1D-CNN) to improve the accuracy of simultaneous quantitative analysis of three metals—Cu, Zn, and Ni in electroplating wastewater—based on VIS absorption spectra data of their colored complexes in aqueous solution with the PAN reagent in the presence of a surfactant. Large datasets were collected from UV-VIS spectra of 500 wastewater spiked samples in the range of 620-500 nm with a 1 nm interval, resulting in a dataset of size 500x121, followed by the application of ML and DL models using the Python programming language. Model performance was evaluated based on the correlation coefficient (R²) and root mean square error (RMSE). Preprocessing methods such as first-order derivatives and Principal Component Analysis (PCA) were applied to reduce noise in the dataset before training with machine learning algorithms. Results showed that the 1D-CNN model outperformed the others, achieving R² > 0.88 and RMSE < 0.036 for all three analytes. It is supposed by its ability to directly extract nonlinear features from raw data without the need for dimensionality reduction. In contrast, the DT, RF, and even MLP models, which utilized principal component analysis (PCA) for dimensionality reduction, demonstrated significantly lower accuracy due to information loss during the reduction process. The proposed model was successfully applied for rapi…

Systematic review on the relationship between HIV, Antiretroviral Therapy (ART), hyperglycemia and hypercholesteremia
type: item
description: HIV (Human Immunodeficiency Virus) infection continues to be a global public health concern, with millions of people living with the virus around the world, largely due to advances in Antiretroviral Therapy (ART) associated with ostensible prevention campaigns. However, if on the one hand a significant increase in the survival of patients with HIV is observed with the use of ART, on the other hand several studies warn of the adverse effects of prolonged use of ART on the metabolic system, particularly in the induction of a persistent hyperglycemic and hypercholesterolemic state, disorders that contribute to the overall reduction in survival due to the emergence of complications related to prolonged hyperglycemia and dyslipidemia, which motivated the present systematic review on the topic.

High prevalence of cognitive impairment in elderly with diabetes mellitus and associated factors
type: item
description: Cognitive impairment in people with diabetes mellitus (DM) is multifactorial, with evidence that their poor metabolic control is related to impaired cognitive function. Background/Objectives: Identify the prevalence of diabetic older with cognitive impairment and characterize the factors associated with this finding. Methods: Cross-sectional, quantitative, descriptive and analytical research carried out with 246 diabetic older adults followed up in a specialized center in northeastern Brazil. Sociodemographic and clinical variables related to DM2 and evidence of cognitive decline were assessed using the Mini Mental State Examination (MMSE). Results: There was a prevalence of cognitive impairment in 74.4% of the studied sample with an association between cognitive impairment and the variables advanced age (p = 0.003) and female gender (p = 0.025). There was statistical significance between the presence of self-reported cognitive problems and cognitive impairment at evaluation (p < 0.001) and a 1.4 times higher prevalence ratio of cognitive impairment in diabetic underweight than in obese elderly (p = 0.020). Conclusions: The research reveals the high prevalence of cognitive impairment in older adults with diabetes, especially in women and advanced age. It also corroborates the association already described in the international literature between subjective complaints of memory and nutritional status and cognitive decline.

This will instill more trust in the customers' minds, considering responsibly checking everything daily regarding regular sanitization and general cleanliness, as well as compliance with other health protocols and an extremely high standard of hygiene. This, along with good queue and wait time management and contactless methods of payment, will also improve the experience. Business strategies are also changing in response to changes in customer behavior, and digitalization marketing is evolving. Additionally, targeted promotions, discounts, and loyalty programs well-suited for a post-pandemic world enhanced customer retention and satisfaction. In addition, relationships between customers and establishments were improved through personalized marketing campaigns, more transparent communication, and security measures. Improving service delivery has also been critical to customer satisfaction. Those who retrained their staff to operate in the post-pandemic period improved service quality significantly.

Territorial management plan of Quilombo Água Fria in Calha Norte as a tool for dialogue in public policies
type: item
description: The Territorial Management Plan (PGT) of Quilombo Água Fria, located in Calha Norte, is a fundamental tool for strengthening the autonomy and territorial preservation of the quilombola community. This study investigated the implementation of the PGT as a means of dialogue in public policies, with the aim of integrating local demands into government actions. The research revealed that, although the PGT has contributed significantly to the recognition and strengthening of the community, it faces challenges, such as the lack of financial resources, inadequate infrastructure and lack of coordination between the different levels of government. The research found that the PGT is fundamental to promoting sustainability and cultural resistance, but that its effectiveness depends on active community participation and inter-institutional partnerships. The main recommendations include strengthening local governance, training leaders, access to financial resources and the integration of public policies at the local, state and federal levels. In terms of results, the implementation of the plan has brought benefits to the community in areas such as sustainable agriculture and environmental preservation, but it has also faced difficulties in implementing some actions due to the lack of financial support and institutional disarticulation. This paper proposes that the creation of monitoring committees and the strengthening of ongoing dialogue between the community and public managers are key elements in ensuring the long-term success of the PGT, making it an effective territorial management model, both for Quilombo Água Fria and for other quilombola communities in Brazil.

XKFHnet: Xception Kronecker Forward Fractional Net for Intrusion Detection in Cloud
type: item
description: In this new era of on-demand cloud computing, security is crucial. To find breaches in the cloud computing environment, researchers have surveyed a number of intrusion detection methods. The majority of them discuss conventional abuse and anomaly detection methods. By positioning the analysing component outside the virtual machine, usually at the hypervisor, Virtual Machine Introspection techniques are highly useful in identifying various stealth attacks that target user-level and kernel-level processes operating in VMs. Techniques such as Hypervisor Introspection protect the hypervisor and stop a compromised hypervisor from attacking virtual machines that run on it. Through the use of hardware-assisted used in virtualization-enabled technologies, introspection approaches examine the hypervisor. Our paper's primary goal is to present a thorough literature review of the many intrusion detection methods that have been suggested for cloud environments, along with an evaluation of their capacity to detect attacks. To clarify the vulnerabilities in the cloud, we offer a threat model and attack taxonomy. Our taxonomy of IDS techniques offers a thorough analysis of approaches together with their distinguishing characteristics, and it represents the state of the art in classification. In the survey, we have given a thorough understanding of methods based on Virtual Machine Introspection and Hypervisor Introspection. With the help of our study, researchers should be able to start investigating intrusion detection techniques in cloud environments.
