Authors: García Rodríguez Cristhian , Maldonado Cornejo Manuel Esteban
Published: December 2024

Los sifonápteros, conocidos comúnmente como pulgas (Siphonaptera), constituyen un problema significativo de salud pública en varias regiones del mundo. En la región montañosa de Ecuador, se ha reportado un aumento en la frecuencia de casos de alergia a Siphonaptera en los últimos años, lo que destaca la urgencia de realizar investigaciones en este tema. Objetivo. Este estudio busca analizar la prevalencia de alergias a Siphonaptera en la región serrana de Ecuador, identificar los factores que contribuyen a su aparición y evaluar las estrategias de manejo y prevención existentes. Metodología. Esta investigación adopta un enfoque mixto, integrando métodos cuantitativos y cualitativos, con un alcance descriptivo y un diseño no experimental. Los estudios revisados se basan principalmente en técnicas de observación directa, pruebas clínicas y pruebas de laboratorio, empleadas para analizar los casos de alergia por Siphonaptera y sus posibles alérgenos. Se realizó una revisión sistemática y analítica de los casos reportados en la región sierra, mismos que fueron comparados con datos de países europeos, y se abarcó un total de 28 artículos relacionados con la alergia a Siphonaptera. Resultados. La alergia a Siphonaptera y sus alérgenos se consideran un problema de salud pública relevante, dado que se ha documentado una alta prevalencia de infecciones asociadas. Estudios previos, como los de Cortez (2018) y Torrez (2023), han investigado protozoos y alérgenos relacionados. Se estima que aproximadamente el 60% de los animales, principalmente perros y gatos, en la región sierra de Ecuador, sufren algún tipo de alergia causada por pulgas y subespecies locales. Conclusiones. A partir de la revisión, se concluye que no existe un estudio exhaustivo sobre la alergia a Siphonaptera en la región, lo que sugiere la necesidad de un enfoque investigativo renovado sobre las infestaciones en diversas áreas de Ecuador.

Published: December 2024

A atual estrutura alimentar global para animais enfrenta desafios de eficiência e sustentabilidade devido à competição por recursos entre rações animais e alimentos destinados ao consumo humano. Ingredientes convencionais, como milho e farelo de soja, que dominam a dieta de aves, apresentam altos custos e significativo impacto ambiental, especialmente na Amazônia, onde esses produtos são ainda mais onerosos. Este estudo tem como objetivo apresentar um panorama das aplicações de subprodutos amazônicos na alimentação de aves de produção, explorando seus efeitos produtivos e econômicos. Ingredientes regionais, como mandioca, tucumã, açaí e buriti, mostram-se promissores devido ao seu valor nutricional, competitividade econômica e viabilidade como substitutos parciais dos insumos convencionais. Estudos indicam que esses subprodutos contribuem para uma produção mais circular e sustentável, reduzindo a pressão sobre terras aráveis e a dependência de recursos externos. Conclui-se que o uso de subprodutos amazônicos na avicultura não apenas reduz os custos de produção, mas também atende à crescente demanda por produtos mais naturais e de menor impacto ambiental. Assim, a exploração de ingredientes regionais consolida-se como uma estratégia viável e sustentável para a avicultura, promovendo uma economia local mais resiliente e ecologicamente responsável.

This paper introduces a novel three-axis flexible tube sensor designed for force measurement in electric vehicle (EV) charging port alignment, utilizing long short-term memory (LSTM) networks. The research aims to develop and validate a flexible and accurate sensor system capable of predicting multi-axis forces during alignment. The sensor integrates a magnetic sensor at the center of a flexible tube to capture three-dimensional (3-D) magnetic field variations corresponding to force changes. Fabricated using thermoplastic polyurethane (TPU) via 3-D printing technology, the sensor leverages machine learning to predict force values along the , , and  axes ( , , ). Finite element method (FEM) analysis was conducted to assess the deflection characteristics of the flexible tube under various force conditions. Experimental results demonstrate that integrating LSTM significantly enhances the accuracy of force prediction, achieving an R² score exceeding 97 % for all axes, with mean squared error (MSE) values of 0.2819 for the -axis, 0.3567 for the -axis, and 2.8086 for the -axis. The sensor is capable of measuring forces up to 30 N without exceeding its elastic limits. These findings highlight the sensor’s potential for improving alignment accuracy and reliability in automated EV charging systems.

The advancement of autonomous vehicle technology has markedly evolved during the last decades. Reliable vehicle control is one of the essential technologies in this domain. This study aims to develop a proposed method for controlling an autonomous personal mobility vehicle called SEATER (Single-passenger Electric Autonomous Transporter), using Non-linear Model Predictive Control (NMPC). We propose a single-shooting technique to solve the optimal control problem (OCP) via non-linear programming (NLP). The NMPC is applied to a non-holonomic vehicle with a differential drive setup. The vehicle utilizes odometry data as feedback to help guide it to its target position while complying with constraints, such as vehicle constraints and avoiding obstacles. To evaluate the method's performance, we have developed the SEATER model and testing environment in the Gazebo Simulation and implemented the NMPC via the Robot Operating System (ROS) framework. Several simulations have been done in both obstacle-free and obstacle-filled areas. Based on the simulation results, the NMPC approach effectively directed the vehicle to the desired pose while satisfying the set constraints. In addition, the results from this study have also pointed out the reliability and real-time performance of NMPC with a single-shooting method for controlling SEATER in the various tested scenarios.

Published: December 2024

This paper proposes an event-triggered formation control scheme to manage the operation of multiple quadrotors in performing the inspection of a power transmission line. In particular, the problem of controlling such multi quadrotors to track the tower and/or cables of the transmission lines is considered. A multi-agent sliding mode control method is used for this purpose and is equipped with both a radial basis function neural network as an estimator of environmental wind disturbances, as well as an event-triggered scheduling scheme for the control execution framework. The proposed multi quadrotors control method is designed by considering the transmission tower/cable as the reference sliding surface. Simulation results are presented to illustrate the effectiveness of the proposed multi quadrotors control scheme when implemented in a case scenario of tracking the commonly-encountered shape of transmission cables. Simulation results are presented and show how the implementation of a position error-based event-triggered control enables all UAVs to track the desired position and maintain a pre-determined formation. In particular, all UAVs can minimize the tracking error within 0.05 m after reaching the desired positions since the control signal is updated if the error reaches such an error bound.

Authors: Wasiatno Juan Marco Alexander , Pratomo Leonardus Heru
Published: December 2024

DC-DC Interleaved Boost Converter (DC-DC IBC) topology was developed through the interleaving technique since conventional DC-DC Boost Converter has many problems related to complex circuit control, harmonics, and output power. In this research, DC-DC IBC was developed into a Two-Phase AC-AC Interleaved Boost Converter (TP AC-AC IBC), then combined with a Two-Phase Full Bridge Inverter to become a Two-Phase DC-AC Interleaved Boost Inverter (TP DC-AC IBI). TP DC-AC IBI has several advantages, including minimal current and voltage ripples and greater output power because it consists of two AC-AC IBCs. This research aims to meet highly regulated AC voltage needs with the renewable energy source input using the proposed topology, by implementing Proportional Integral (PI) close loop control system. The output voltage is detected using a voltage transducer LV-25P, then compared with a reference voltage and controlled using a PI controller to keep the output voltage consistently stable. The switching signal setting uses the Sinusoidal Pulse Width Modulation (SPWM) technique by modulating the control output with a high frequency. As a verification step, testing was carried out using Power Simulator (PSIM) software and then validated by hardware testing in the laboratory. Testing was carried out using several test signals, and it was found that the proposed method worked well. System efficiency and Total Harmonic Distortion (THD) tests carried out using various load values, and a maximum efficiency of 93.87% and a minimum THD of 2.46% were obtained.

This article presents the development of SIDASIBELO (Landslide Information and Mitigation System), an Android-based application for real-time landslide monitoring and early warning. This system integrates data from several sensors that measure soil moisture, rainfall, slope angle, and ground vibrations at the monitored locations. The Firebase Real-time Database stores and transmits sensor data, while Firebase Cloud Messaging and OneSignal enable push notifications to alert users about potential landslide risks. There are four output status levels: SAFE, ALERT, CAUTION, and WARNING, which are determined based on a comprehensive analysis of the monitored parameters. Mitigation strategies include real-time parameter monitoring, early warnings, evacuation guidance, and user education on landslide preparedness. Testing on several Android devices demonstrated high compatibility, with an average successful server connection rate of 92.86%. Latency tests indicated an average response time of 894 ms from the input device to the database, 1.29 ms from the database to the Android device, and 2725 ms for push notifications. The system's total daily bandwidth usage for real-time data transmission is 27,648 MB, indicating high efficiency without overburdening the server's performance. While the app operates efficiently under ideal conditions, unstable network connections can lead to data retrieval failures or, in worst cases, app malfunctions. This remains a key challenge for our system. This system aims to raise awareness of landslide risks and enable timely evacuation, which could potentially reduce the negative impacts of landslides in vulnerable areas.

This research is of significant importance as it discusses the modelling of a two-dimensional map of soil parameters in Bengkulu City, Bengkulu Province, Indonesia. The two-dimensional modelling was conducted to show the distribution of soil parameter values based on the research points strategically distributed throughout Bengkulu City. These research points were chosen to represent the diverse soil conditions in the city, making the modelled soil parameters particularly helpful for engineers and construction consultants when planning construction in the study area. The parameters to be discussed include shear wave velocity, cone resistance, and corrected standard penetration test. This modelling applies Inverse Distance Weighting as an interpolation method from 215 research points. Inverse Distance Weighting is used because it supports knowing the value of soil parameters around the review point, especially in two-dimensional modelling. The results showed that the distribution of the highest value of shear wave velocity of the clay layer is dominated in the Teluk Segara sub-district. The distribution of the highest value of cone resistance of the clay layer is dominant in the Kampung Melayu Sub-district. The distribution of the highest value of corrected standard penetration test of the clay layer is also dominated in Kampung Melayu Sub-district.

Published: December 2024

Global climate change and human interference are progressively increasing the level of salt-affected land, thereby diminishing the availability of agricultural land and compromises food quality. Current experiment was conducted on salt-affected agricultural land contaminated by shrimp farm at Thandavarayan Sholangan Pettai, Cuddalore district, Tamil Nadu, utilizing Salicornia brachiata a biological tool to assess its efficacy in mitigating salinity. This study was conducted over a period of 4-months to determine the morpho-anatomical variations, biochemical, antioxidant enzymes and soil physico-chemical properties. The results demonstrated that Salicornia brachiata exhibits a robust phytoaccumulation capacity of 290 kg NaCl ha-1 which also led to a decrease in the soil pH from 8.8 to 6.83, electrical conductivity from 5.7 to 1.96 dSm-1 and sodium adsorption ratio from 17.2 to 6.5 mmol L-1. Gradual increase in plant height, biomass, stem thickness, biochemical, and antioxidant enzyme activity was noticed throughout the experimental period when compared to the control. Revegetation can be possible through successive cultivation of Salicornia brachiata in a salt-affected lands, thereby alleviating a significant constraint on crop productivity.

Published: December 2024

Fenugreek (Trigonella foenum-graecum) is widely recognized for its medicinal and pharmaceutical value. However, salinity stress is a major abiotic factor that negatively impacts plant growth and development. This study aimed to examine the effects of different salinity concentrations (50, 100, 150, 200, and 250 mM NaCl) on the physiological and biochemical parameters of fenugreek. Fenugreek is highly regarded for its medicinal and pharmaceutical benefits, yet salinity stress poses a significant challenge to its growth and productivity. This study explored the effects of varying salinity levels on the physiological and biochemical responses of fenugreek. Salinity stress was found to inhibit seed germination, reduce plant biomass, and adversely impact moisture content and chlorophyll levels. While fenugreek demonstrated some tolerance to moderate salinity levels, higher concentrations severely affected its growth and physiological traits. These findings highlight the importance of managing salinity to enhance fenugreek's agricultural performance and productivity.
Evolution of Crushing Surface of Ta-d Pumice in Triaxial Compression Tests
Authors: Sato Itsuki , Kuwano Reiko , Otsubo Masahide , Mouri Atsushi
Published: December 2024

Crushable porous granular materials like volcanic pumice, distributed worldwide, cause various engineering problems, including slope hazards. These materials are often classified as problematic soils due to their complex mechanical properties, which arise from high compressibility and changes in grain size due to particle crushing. Consequently, their behaviour is typically discussed on a case-by-case basis, and a systematic understanding has yet to be established. This study aims to elucidate the relationship between the mechanical properties and particle crushing of porous granular materials through a series of tests on natural volcanic pumice. The intra-particle void ratio was measured alongside isotropic consolidation and CD/CU triaxial compression tests, with particle crushing assessed before and after the experiments. The results indicate that the intra-particle void ratio correlates with particle size, with larger particles generally having higher porosity. Additionally, the mechanical behaviour of these materials shows high compressibility, and their stress paths resemble those obtained from undrained triaxial tests on loose sand, ultimately reaching the critical state. The relationship between the amount of particle crushing and mean effective stress at the end of the tests can be represented by a single curve for isotropic consolidation tests, CD, and CU triaxial tests, respectively. The amount of crushing generally increases with the progression of axial strain during the compression process, and in CU tests, when reaching the critical state, no further increase in crushing occurs with increased axial strain. Furthermore, critical state and isotropic consolidation state of each material can be represented on its own unique surface, each referred to as a "Crushing Surface," defined by the crushing volume, void ratio, and mean effective stress for that specific soil.

The application of biochar in geotechnical and geoenvironmental engineering remains relatively understudied, particularly concerning its impact on soil properties when mixed with sugarcane bagasse. This study investigates the influence of sugarcane bagasse-derived biochar on the strength and water retention behavior of low plastic clay soil, representing a novel contribution to the field. Biochar, a carbon-rich material produced by the pyrolysis of organic biomass, has garnered attention for its potential to enhance soil properties and mitigate environmental challenges. Five different percentages of bagasse biochar (0%, 1%, 2%, 3.5%, and 5%) were incorporated into the low plastic clay soil to prepare biochar-amended soil specimens. Unconfined compressive strength and water retention tests were conducted to evaluate the mechanical and hydraulic properties of the amended soils. The findings reveal that the water retention capacity of the biochar-amended soil increased with the addition of bagasse biochar. This observation suggests that biochar incorporation enhances the soil's ability to retain moisture, potentially beneficial for mitigating soil moisture fluctuations and supporting plant growth in geoenvironmental applications. Furthermore, the study also highlights a positive impact on the strength properties of the soil with a 22.1% increase for 1% biochar content compared to no-amended after 28 days. This increase in strength was attributed to changes in soil structure, pore distribution, and inter-particle bonding induced by the presence of biochar. In conclusion, Biochar amendment offers potential for enhancing soil water retention and strength properties and the use of sugarcane bagasse-derived biochar in low plastic clay soil presents promising opportunities for geoenvironmental engineering applications.

Objective: The objective of this narrative literature review article is to address the electronic cigarette, an invention created in recent years, which has been widely used by adolescents, young people and adults, and is a product that has been causing several problems in the oral mucosa, dental structure and oral health, impacting in an extremely negative way. Methodology: To construct this narrative literature review article, a methodology was outlined in a thoughtful and strategic way, so that the maximum amount of information that could be added to the topic of the article could be obtained from online books, doctoral and master's theses, course completion papers, case reports, review articles, monographs, PICs and research on the topic addressed. Thus, to obtain this range of information, research was carried out in the following databases and websites: DeCs, BVS/BIREME, PROSPERO, Web of Science, CAPES Periodicals Portal, Science Direct, Scielo, PUBMED Central, The Cochrane Library, LUMEN ET VIRTUS Magazine, FT Magazine, Research, society and development journal combined with the Google Academy website. Results: The electronic cigarette was initially created as something that was supposed to be less corrosive and would cause fewer problems than the conventional cigarette, being something that was created for people who already smoke, so that they would start using this “healthier” cigarette, until the dependence diminished so that smokers could later quit all types of cigarettes. Conclusion: Thus, it is seen that the electronic cigarette has a range of harmful effects on the human body, being a product that causes problems in the oral cavity.

The process of human identification in the forensic area is fundamental in several circumstances, especially mass accidents and tragedies. Forensic dentistry plays an important role in this environment, with the use of modern technologies such as cone beam computed tomography for the investigation of determining parameters in the identification of sex. The objective of this article was to analyze whether it is possible to identify the sex of patients from the mandible, analyzing morphological and morphometric patterns predominant in males and females. This study used a sample of 100 cone beam computed tomography (CBCT) scans, 50 male and 50 female. CBCT scans were analyzed using the RadiAnt DICOM® software in the 3D tool, visualizing three morphological patterns and nine morphometric patterns. With results of almost 100% accuracy, this study reveals that it is possible to identify sexual dimorphism through mandibles. The morphological patterns of chin shape, muscle marking, and gonial reflex revealed a marked sexual dimorphism. Morphometric analyses of the mandible measured at different sites and their combinations revealed satisfactory results and can be used to identify sexual dimorphism. Thus, the results of this work may be a useful tool in the forensic practice in diagnoses and recognition of the individual's sex in the forensic area.

This study aimed to perform a systematic review of the literature on the sociodemographic and psychological profile of psychoactive substance users hospitalized in Intensive Care Units (ICU), as well as their clinical characteristics and treatments. To this end, a search for articles on the subject was carried out in the PubMed, Scopus, VHL and Pepsic databases. Empirical articles in Portuguese, English, and Spanish, published between 2014 and 2024, were selected. After applying inclusion and exclusion criteria, 12 studies that met the present proposal were selected. As main results, it was identified that patients using psychoactive substances admitted to the ICU were predominantly men, with a mean age of approximately 40 years, with alcohol being the most used substance among them. In addition, it was found that the primary or secondary cause of hospitalization was associated with the abusive consumption of psychoactive substances, and it was evident that such practices could influence the clinical outcome. It is believed that this review can stimulate the development of research on this scarce topic, in addition to helping intensive care health professionals, especially psychologists, in the care of this portion of the population that tends to be stigmatized and that often have their demands made invisible.
