En la región Andina del Ecuador la mayor superficie destinada a la agricultura está en manos de pequeños agricultores que no tienen acceso a tecnologías. Como resultado de ello se visibiliza el bajo rendimiento de sus cultivos, aumentando la vulnerabilidad de sus sistemas productivos por otros factores como: la sequía, las bajas temperaturas y la falta de mano de obra por la elevada migración. El uso de acolchado plástico en la agricultura es una tecnología que permite aumentar los rendimientos a través del empleo eficiente del agua, el aprovechamiento de los nutrientes, el adelanto de las cosechas y la calidad del producto; además que permite un ahorro significativo de mano de obra, que cada vez es más escaso y costoso en el campo. El objetivo de esta investigación fue evaluar el efecto del sistema de siembra en acolchado plástico sobre el comportamiento agronómico y la rentabilidad de cuatro variedades maíz de diferentes tipos de grano: INIAP-101 (blanco harinoso), INIAP-122 (amarillo harinoso), INIAP-193 (negro harinoso) e INIAP-199 (chulpi-dulce). Para el efecto, se establecieron cuatro experimentos independientes con un diseño experimental de bloques completamente al azar, con tres repeticiones en dos provincias de la Sierra del Ecuador. Se evaluaron dos tratamientos: (T1), acolchado plástico y (T2), manejo convencional (sin acolchado). El sistema de acolchado plástico incrementó significativamente (p<0,01) la altura de planta y el rendimiento, pasando de un promedio de 1,55 a 2,01 m de altura y de 2,91 t ha-1 a 4,95 t ha-1 de grano, respectivamente. El incremento promedio del rendimiento de grano en los cuatro ensayos fue del 85 % respecto al del manejo convencional. La relación B/C promedio fue de 2,14 para el sistema convencional y de 2,55 para el sistema con acolchado. El costo unitario de producción por kilo de grano producido fue más bajo en el sistema con acolchado, con un promedio de 0,67 USD kg-1, en comparación con el sistema convencional, que tuvo un promedio de 0,77 USD kg-1. Los resultados obtenidos permiten concluir que el cultivo con acolchado plástico puede ser una alternativa para intensificar de manera sostenible la producción de maíz en la región Andina y mejorar los ingresos de los productores.
Entre la dominancia social y el empoderamiento femenino todavía hay una brecha que cerrar

Published: December 2024

A reflection is presented on the gender gap that exists so that women can generate agency and, consequently, talk about empowerment. This is due to factors based on social dominance. Power relations are an inherent topic in gender studies because it is through this form of domination over others that discrimination is generated. This, based on the social need for the establishment of hierarchies for control and unequal treatment between people and groups. It is still necessary to close the gap of inequality and exclusion for people who are still immersed in categories of inferiority due to their age, religion, sexual orientation, social origin and language, which produces discrimination. In Mexico it is a serious problem because the ideas of classism, homophobia, xenophobia that have already done enough damage remain, relegating people from actively participating in the construction of an egalitarian society, where the rights established by the Mexican Constitution really apply to everyone. and all, as stipulated in its first article.

Published: December 2024

Summary
Gas/liquid separators (GLSs) are widely used in petroleum extraction and the chemical industry, as well as aerospace and other fields. Experimental studies and numerical simulations were conducted to investigate the impact of tip clearance (TP) on the separation performance and energy characteristics of a dynamic GLS. The Reynolds stress model (RSM) was used for the numerical simulation of the gas/liquid separation process, and the reliability and accuracy of the model were confirmed through comparison and analysis of experimental findings. The results demonstrate a linear correlation between TP and device performance under specific flow rate conditions. As TP increases, there is a corresponding decrease in separation efficiency, power of the liquid-phase outlet (LPO), and differential pressure at the inlet. This trend can be attributed to reduced maximum tangential velocity and increased TP, which lead to heightened backflow. Consequently, this impedes the outflow of the liquid phase post-separation, resulting in reduced separation efficiency and energy performance. Furthermore, at particular TPs, a significant decline in device performance is observed under conditions of high flow rates. This is primarily due to the intensified turbulence between the blades, which increases flow rates. Consequently, the disorder in the internal flow field escalates, leading to considerable energy losses and impacting the gas/liquid two-phase separation process. This study offers valuable insights into designing high-performance dynamic gas/liquid separation devices (DGLSDs), providing a robust theoretical foundation for future endeavors.
Performance Comparison Of SDN Controllers In Different Network Topologies

Published: December 2024

Abstract

The development of Software-Defined Networking (SDN) has completely changed the way networks are optimized and controlled. Still, network topologies and SDN controller performance are important factors that need to be thoroughly examined. In this study the evaluation of four well-known SDN controllers: Ryu, Floodlight, OpenDayLight, and ONOS across five different network topologies: Single, Linear, Tree, Torus, and Custom are examined. We conducted extensive experiments using Mininet and Iperf to measure latency, jitter, packet loss, and throughput. It is clear from the results that Ryu performs better than the others, and Linear topology is the most effective. Notably, the best performance is obtained when Ryu and Linear topology work together. Our results suggest that Ryu and linear topology are the best combination for high-performance networks, which has significant implications for the design and deployment of SDN networks. On the other hand, other controllers and topologies are more suitable for certain use cases, such as large networks, research and development, small networks, and custom applications. this study provides invaluable information for researchers, practitioners, and network administrators looking to maximize SDN network performance and realize its full potential.

Abstract

Timely replacement of cutting tools reduces machining costs and prevents the manufacture of defective products. Many researchers have developed Tool Condition Monitoring (TCM) systems to estimate tool wear using reliable, low-cost instrumentation. This paper proposes estimating tool wear by interpreting motor current signals from the programming logic controllers (PLCs) of CNC machines with artificial intelligence (AI) tools.
Experimental data were collected from three cutting tools at four wear states: normal, and with one, two, or three worn cutting edges. Four AI models were used to classify normal and anomalous cases: 1D Convolutional Neural Networks (1D CNN), Long Short-Term Memory (LSTM) networks, a hybrid 1D CNN-LSTM architecture, and an LSTM autoencoder. Hyperparameter tuning was performed to optimize each model.
Three approaches were explored to address different production needs:
· Approach A - Supervised Learning: 1D CNN showed the best performance, achieving 90% validation accuracy.
· Approach B - Semi-Supervised Learning: An LSTM autoencoder trained only on “normal” data achieved 96% validation accuracy but a low F1 score of 0.51, indicating limited anomaly detection capability.
· Approach C - Transfer Learning: Using transfer learning, the 1D CNN model reached 85% validation accuracy and an F1 score of 0.84 when tested on a third tool with a different diameter.

Abstract

Background
Cardiovascular diseases (CVDs) are the leading cause of global mortality, claiming 17.9 million lives annually. Major behavioral risk factors include unhealthy diet, physical inactivity, tobacco use, and excessive alcohol consumption. Text messaging interventions can potentially improve individual risk factors and encourage healthy habits. They have been shown to manage risk factors and disease progression. This systematic review and meta-analysis aimed to evaluate the efficacy of text messaging interventions for the primary prevention of CVD risk factors.
Methods
This review followed the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020 guidelines. Searches were conducted on PubMed, MEDLINE, Cochrane, Scopus, Web of Science, Embase, and CINAHL using MeSH and free-text terms related to cardiovascular disease and text messaging interventions on 18/03/2024.
Results
Out of 6142 identified articles, 22 studies met the inclusion criteria. The meta-analysis revealed that text messaging interventions significantly improved medication adherence, with a pooled effect size of Mean Difference (MD) of 0.61 (95%CI: 0.37 to 0.85; p < 0.0001, I² = 0.0%). They also significantly reduced diastolic blood pressure by MD of -2.66 (95% CI: -4.62 to -0.70, I² = 85%, p = 0.007) and systolic blood pressure by MD of -6.11 (95% CI: -10.25 to -1.97, I² = 96%, p = 0.003). However, no significant improvements were observed in BMI, LDL, HDL, total cholesterol, or HbA1c levels.
Conclusion
Text messaging interventions effectively improve medication adherence and help in the reduction of blood pressure, making them a promising tool for CVD risk control. However, their impact on other cardiovascular risk factors is limited, indicating the need for further research to explore long-term effects and personalized interventions for diverse populations. Integrating these digital tools into healthcare strategies could enhance CVD prevention efforts and improve cardiovascular risk factors control outcomes.

Abstract

Objectives
Tinnitus affects millions worldwide. Its neural mechanisms remain unclear. This study aimed to explore the causal relationships between brain functional networks and tinnitus risk using Mendelian randomization (MR) analyses.
Methods
We performed MR analyses using brain activity data from resting-state functional magnetic resonance imaging (rsfMRI) and genetic data from genome-wide association studies (GWAS). A total of 191 brain features, including amplitude traits and functional connectivity measures, were selected based on their genetic associations.
Results
Forward MR analyses showed that increased activity in the parietal and inferior frontal regions was associated with a 41% reduction in tinnitus risk (OR = 0.59, p = 1.8 × 10–4). In contrast, increased activity in the precuneus, angular gyrus, and frontal areas was linked to a 49% increase in tinnitus risk (OR = 1.49, p = 8.9 × 10–4). Activities in the parietal and inferior frontal regions were negatively correlated with tinnitus risk (OR = 0.72, p = 0.0037). Additionally, higher activity in the parietal, frontal, and temporal regions doubled the risk (OR = 2.02, p = 0.015). Reverse MR showed that stronger connectivity between frontal and temporal regions was inversely related to tinnitus risk (OR = 0.95, p = 0.049).
Conclusions
Specific brain activity and connectivity patterns are causally linked to tinnitus.

Abstract

The possibility of reducing energy costs during hydrogen release was realized using a system in which the anodic process of oxygen release was replaced by the process of dissolution of an electronegative metal (aluminum alloy). The rate of hydrogen release on aluminum, among other equal conditions (temperature and concentration of the electrolyte), depends on the polarization of hydrogen release. On aluminum - a metal of the third group of the periodic table of elements, it is high. The dissolution (corrosion) rate of aluminum can be increased by short-circuiting with an electrode with a low hydrogen evolution polarization, such as nickel. The ratio of hydrogen evolution currents on aluminum and nickel was estimated. The effect of alkali concentration and temperature on the current density, polarization and polarizability of electrodes made of aluminum alloy containing Cu, Mg, Mn and Fe was determined. It was shown that in a 0.1 mol l− 1 NaOH solution at a temperature of 20°C, the polarization resistance of hydrogen release on nickel is lower than on aluminum, and the hydrogen release rate on Ni is higher. At high temperatures and sodium hydroxide concentrations, the polarizability of metal dissolution and hydrogen release on aluminum increases sharply and exceeds those on nickel.

Abstract

Background
Increased levels of emotion dysregulation and impulsive behavior are overlapping symptoms in Attention-Deficit/Hyperactivity Disorder (ADHD) and Borderline Personality Disorder (BPD), both symptom domains reflect on inhibitory control, although from different angles. Our aims were to describe their differences in the above conditions, investigate their associations with childhood traumatization, and to explore the potential mediation of emotion dysregulation and impulsivity between childhood traumas and personality functioning.
Methods
Young adults between 18–36 years diagnosed with aADHD (n = 100) and BPD (n = 63) were investigated with structured clinical interviews, while age-matched healthy controls (n = 100) were screened for psychiatric disorders. Patients with aADHD-BPD comorbidity were excluded from the analyses. The Difficulties in Emotion Regulation Scale, the Barratt Impulsiveness Scale, the Childhood Trauma Questionnaire-Short Form and the Level of Personality Functioning Scale were administered to investigate trait measures and childhood traumatization. Behavioral impulsivity and delay aversion were assessed using selected tests of the Cambridge Neuropsychological Test Automated Battery, and a computerized decision-making paradigm based on the Rogers’ decision-making task, respectively.
Results
Significantly higher levels of emotion dysregulation and impulsivity were present both in the aADHD and BPD groups, however with different inhibitory profiles. Waiting and stopping impulsivity was selectively higher among aADHD patients compared to healthy controls. The BPD group demonstrated higher levels of delay aversion among uncertain conditions in the decision-making task. Higher levels of childhood trauma were associated with emotion dysregulation, trait impulsivity, and delay aversion across groups. Emotion regulatory capacity played a significant mediating role between childhood traumatization and the level of personality functioning.
Conclusions
Inhibitory control profiles of the aADHD and BPD groups were divergent. Childhood traumatization was associated with lower levels of personality functioning in adulthood, independently of diagnosis. In our models the effect of trauma was mediated more by emotion dysregulation, rather than impulsivity. These findings have various clinical implications for the diagnosis and treatment of aADHD and BPD.

Abstract

Background: Frequent recurrence is responsible for persistent Plasmodium infection after the acute stage. Our previous study demonstrated that phagocytic cells are essential for controlling Plasmodium chabaudi chabaudi AS (P. chabaudi) recurrence. Nevertheless, the specific type of phagocytic cells involved in controlling P. chabaudi recurrence, as well as their underlying molecular mechanisms of action, remain elusive.
Methods: Single-cell RNA sequencing (scRNA-seq) was employed to analyze splenic phagocytic cells during both the acute and recurrent phases of P. chabaudi infection. The frequencies of red pulp macrophages (RPMs), classical monocytes (CMs), and non-classical monocytes (NCMs) were detected by flow cytometry. Low-dose clodronate liposomes (CLs) and CCR2-/- mice were used to investigate the protective role and origin of NCMs.
Results: Using scRNA-seq, we found that NCMs declined during the acute stage of P. chabaudi blood-stage infection, and then expanded rapidly in the recurrence stage. The changing trend of NCMs was confirmed by flow cytometry. To explore the potential role of NCMs in controlling parasitemic recurrence, NCMs were selectively depleted by a low-dose of CLs during the recurrence stage, which significantly elevated the P. chabaudi parasitemia. Additionally, no significant difference in the proportion of splenic NCMs or CMs within the monocyte population was observed between the infected CCR2-/- mice and their control littermates, suggesting that the transition from circulating CMs to NCMs may not occur in this model.
Conclusions: In summary, our results indicate that NCMs potentially play a protective role in preventing malarial parasitemic recurrence, offering valuable insights into immune-based interventions against Plasmodium infection and potentially contributing to the prevention of malaria transmission.
