Diseño de concreto de f’c = 350 kg/cm2 con residuos de ladrillo sílice calcáreo pulverizado y fibra de basalto para mejorar la resistencia frente a sulfatos y cloruros en estructuras verticales de edificios cercanos al mar en Lima Metropolitana(Universidad Peruana de Ciencias Aplicadas (UPC)PE, 2026-03-10)El concreto armado se ha convertido en un material predilecto en la construcción de edificaciones debido a su elevada resistencia mecánica, costo accesible y prolongada durabilidad. Sin embargo, presenta grandes desafíos cuando se emplea en ambientes agresivos con altos niveles de sulfatos y cloruros, ya que estas sustancias deterioran el material y reducen sus propiedades físico-mecánicas a largo plazo. En los últimos años, diversas investigaciones han analizado la incorporación de materiales cementicios suplementarios como una alternativa para contrarrestar dicha problemática. La presente investigación propone un diseño de concreto de 350 kg/cm², incorporando residuos de Ladrillo Sílice Calcáreo (LSC) finamente molido y Fibras de Basalto (FB), con el fin de aumentar su durabilidad frente al ataque de sulfatos y cloruros. Se evaluaron cuatro mezclas con porcentajes de 5% y 10% de LSC, reforzadas con 0.5% de FB. Asimismo, se analizaron la resistencia a la compresión y a tracción indirecta por compresión diametral a edades de 7, 14 y 28 días, además de ensayos de carbonatación y pérdida de masa a 360 días de exposición en agua de mar. Los resultados evidencian que la mezcla de concreto 5% LSC 0.5% FB presenta el mejor desempeño frente al ataque de sulfatos y cloruros, de acuerdo con los ensayos de carbonatación, pérdida de masa y resistencia mecánica. Dicha muestra superó al concreto patrón en los ensayos de resistencia a compresión, tracción indirecta por compresión diametral, carbonatación y pérdida de masa en 3.21%, 10.39%, 36.11% y 39.87%, respectivamente; siendo la muestra con la dosificación óptima.

Exploring the Seismic Performance of Confined Brick Masonry Walls via Diverse Toothing Connections: A Numerical Investigation(American Society of Civil Engineers (ASCE), 2026-02-01)Confined brick masonry (CBM) combines masonry walls with reinforced concrete ties for enhanced structural integrity. The wall-to-tie connection is essential for effective load transfer, preventing out-of-plane failure, and enhancing ductility. Introducing tie-columns into masonry walls through various toothing connections is crucial. However, previous research and guidelines do not provide clear insights into their specific contributions, making it difficult to accurately assess their impact. Addressing this gap, our study employed a robust numerical approach, utilizing an integrated finite element macromodel that treated wall and tie members as a single entity, thereby improving computational efficiency. Additionally, the study applied the concrete damage plasticity model to predict damage progression in CBM walls and performed pushover analysis to evaluate the seismic performance of various toothing schemes in CBM walls. An extensive parametric study was conducted to compare various toothing schemes, evaluate the optimal horizontal and vertical projections of tooth, assess the impact of height-to-thickness ratio on toothing schemes, and investigate the effect of openings on the performance of toothing schemes in CBM walls. This research also assessed the severity of damage encountered by CBM walls, providing insights into crack propagation and distribution and emphasizing the significance of its design. This study highlights the critical role of toothing schemes in the seismic performance of CBM walls, with the machine-made toothing schemes demonstrating superior results. These schemes significantly enhanced ultimate strength, stiffness, and energy absorption compared to handmade, horizontal reinforcement, and no-tooth options. The research also quantified the positive correlation between increased wall thickness and improved structural resilience, particularly when paired with machine-made toothing. Furthermore, the study identified the adverse effects of wall openings on seismic performance, emphasizing the importance of precise tooth size and arrangement. Notably, a 100-mm vertical projection was shown to offer the most effective seismic performance, providing valuable, data-driven guidelines for the design of earthquake-resistant CBM structures.

Unveiling Injustice: Analyzing Child Mortality Inequality across decades in Peru (1981–2017)(Elsevier Ltd, 2026-01-01)Peru is a developing country that has significantly improved the average of almost all health indicators. Specifically, in the past four decades, child mortality decreased tenfold. However, the same is not necessarily true of equality, which remains a challenge. Using microdata from Peru's population censuses in 1981, 1993, 2007, and 2017, we estimate the inequality in child mortality across different social groups. We estimate differences between ethnic groups, education levels, wealth quintiles, regions, and urban–rural groups and find that although inequality has decreased, it remains significantly high. The data show that inequality in child mortality increased between 1981 and 1993, declined between 1993 and 2007, and then increased between 2007 and 2017. Differences in education are the most crucial factor, associated with 45 % of the inequality in 1981 and 58 % in 2017. Differences between Lima and rural areas account for 27 % to 30 % of the inequality, while ethnicity contributes only 6 % in 1981 and 10 % in 2017.

A Thorough Evaluation of Demand Prediction Models: Machine Learning, Deep Learning, and Statistical Techniques for Import Businesses(Springer Science and Business Media Deutschland GmbH, 2026-01-01)Nowadays, managing demand in companies is crucial to avoid storage overcosts, stockouts and to improve the service level of companies. To address this scenario, demand predictions through models and algorithms emerge. Therefore, this research aims to evaluate the performance of seven prediction techniques applying machine learning, deep learning, and statistical methods. To validate our experiments, we used Dickey–Fuller, Shapiro–Wilk, Friedman, and Wilcoxon post-hoc statistical tests on the predictions of the models using demand records from a Peruvian import company. The results indicated that deep learning and statistical models have significantly better predictions than machine learning models. In particular, the LSTM, CNN, ARIMA, and Holt-Winters models significantly improve accuracy compared to the Ridge Regression, Random Forest Regressor, and Decision Tree Regressor models. Compared to machine learning models, statistical and deep learning models improve accuracy in a range from 66.01 to 86.10%. These results highlight the statistical advantage of deep learning and statistical models in demand prediction, with the LSTM model showing the lowest error.

Empirical Experiment to Validate Guidelines for Video Game Users With ADHD(Education Society of IEEE (Spanish Chapter), 2026-01-01)Current video game designs often include features that distract users, a problem exacerbated for individuals with Attention Deficit Hyperactivity Disorder (ADHD). To mitigate distractions for this population, specific design guidelines have been proposed. This study evaluates the benefits of applying such guidelines in the software development process of video games for users with ADHD. A controlled experiment was conducted with 16 subjects interacting with two versions of a video game: one designed according to the guidelines and another without them. Metrics analyzed include perceived effort and user satisfaction, measured through Perceived Ease of Use (PEOU), Perceived Usefulness (PU), and Intention to Use (ITU). Results indicate statistically significant differences in effort and satisfaction; users engaging with the guided design reported lower cognitive effort and higher satisfaction. These findings suggest that integrating ADHD-focused design guidelines enhances game accessibility and improves user experience for this demographic.

Influence of economic globalisation on growth and environmental quality in Pacific Alliance countries(Cogent OA, 2026-01-01)This article examines the dual impact of economic globalisation on economic growth and environmental quality within the Pacific Alliance—Chile, Colombia, Mexico and Peru—between 1990 and 2022. Employing a quantitative longitudinal approach, it applies panel data econometric techniques, specifically Fixed Effects models, complemented by robustness checks using Random Effects and Pooled Ordinary Least Squares estimations. Panel unit root tests (Levin–Lin–Chu; Im–Pesaran–Shin) confirmed data stationarity, and the Hausman test validated the suitability of the Fixed Effects estimator. The results show that trade openness exerts a positive and statistically significant effect on real economic growth, suggesting that deeper integration into global markets enhances productive efficiency, diversifies exports and improves resource allocation. By contrast, foreign direct investment does not exhibit a significant relationship with growth, owing to institutional weakness, limited infrastructure and the shallow financial systems that characterise the region. Regarding environmental outcomes, trade openness increases carbon dioxide emissions, indicating that liberalisation stimulates production while exacerbating environmental degradation in contexts with insufficient regulatory capacity. Foreign direct investment likewise shows no significant effects, possibly due to sectoral heterogeneity. The study concludes that the Pacific Alliance must strengthen environmental governance and guide trade and investment towards sustainable development.

Model for Monitoring the Pest Carmenta Foraseminis in Cocoa Crops Through Environmental Parameters(Springer Science and Business Media Deutschland GmbH, 2026-01-01)Cocoa consumption has increased in recent years as it has a significant impact on the food and cosmetic sector. It is therefore important to maintain and improve agricultural productivity, which makes it urgent and necessary to improve management techniques, including fertilization and crop and plantation protection practices. However, intensive cocoa production in Peru and South America faces challenges for cocoa production. The most decisive is the attack of the “mazorquera” pest (Carmenta foraseminis), which infests the fruit inside without giving the possibility of early detection and, consequently, the quality and intensity of the harvest is often diminished. The objective of this work is the development and implementation of a method to monitor and detect the “mazorquera” pest in the cocoa crop, by obtaining data in real time and analyzing them. In this sense, the proposal involves the use of sensors to monitor certain environmental variables that correlate with the behavior of the pest “mazorquera” from certain artificial intelligence algorithms. The use of intelligent algorithms decreases the analysis time, the error rate and increases the accuracy in the decision-making process. The proposed method proves to have the relevant correlation between environmental conditions and the behavior with crop pests, allowing its timely detection to intervene quickly and effectively. The proposed procedure is not limited to the improvement in crop management, it also creates the conditions for improved traceability of information, improving cocoa production, making it more competitive and sustainable.

The KUYUY Accelerograph and SIPA System: Towards Low-Cost, Real-Time Intelligent Seismic Monitoring in Peru(Multidisciplinary Digital Publishing Institute (MDPI), 2026-01-01)Accelerographs are essential instruments for quantifying strong ground motion, serving as the foundation of modern earthquake engineering. In Peru, the first accelerographic station was installed in Lima in 1944; since then, various institutions have promoted the expansion of the national network. However, this network’s spatial coverage and instrumentation remain insufficient to properly characterize strong motion and support seismic risk reduction policies. In this context, the KUYUY accelerograph is presented as a low-cost, low-noise device equipped with real-time telemetry and high-performance MEMS sensors. Its interoperability with the Intelligent Automatic Processing System (SIPA) enables real-time monitoring and automated signal analysis for seismic microzonation studies and rapid damage assessment, contributing to seismic risk reduction in Peru. The validation process included static gravity calibration, field comparison with a reference accelerograph, and an initial deployment in Lima and Yurimaguas. The results demonstrate the proposed accelerograph’s linear response, temporal stability, and amplitude consistency with respect to high-end instruments, with differences below 5–10%.

IoT-based air pollution monitoring system: A case study in Artisanal Brick Kilns(Taylor and Francis Ltd., 2026-01-01)The rapid growth of industrial activities has led to a significant increase in environmental pollution. Exposure to these air pollutants negatively impacts health, quality of life, and contributes to climate change. It is essential to develop accessible and low-cost mechanisms for controlling polluting emissions. This study presents an IoT-based air pollution monitoring system implemented in an artisanal brick kiln, where manual processes and the use of fossil fuels generate emissions that can severely affect nearby communities, particularly due to the high concentration of fine particulate matter such as PM2.5, known to cause respiratory and cardiovascular problems. The system uses the SPS30 sensor to measure PM2.5 and PM10, connected to an ESP32 microcontroller, which transmits data using the MQTT protocol to the AWS IoT Core service, where they are processed and visualized in real time through a web application. During its validation, the system demonstrated high accuracy, obtaining a correlation of r = 0.95 for PM2.5 and r = 0.99 for PM10 compared to an official monitoring station. The experiment at the artisanal brick kiln confirmed that on 100% of the days monitored, PM2.5 concentrations exceeded the limit of 75 µg/m³, while PM10 exceeded 150 µg/m³ on 30% of the days evaluated. The system generates automatic alerts for excessive pollutants, facilitating a timely response and the implementation of corrective measures when pollution levels reach critical levels. The proposal presents a scalable and low-cost solution to improve environmental management across various industrial sectors.
