It is widely acknowledged that disaster risk reduction is a development issue best addressed locally with community involvement, as an integral part of local development. Yet there are many constraints … It is widely acknowledged that disaster risk reduction is a development issue best addressed locally with community involvement, as an integral part of local development. Yet there are many constraints and realities that complicate the attainment of this ideal. This paper reviews the experience in disaster risk reduction in a range of cities, including Manizales, Colombia, which has integrated risk reduction into its development plan and its urban environmental management. The city government has also established an insurance programme for buildings that provides coverage for low-income households. The paper further describes and discusses the experiences of other city governments, including those of Santa Fe in Argentina and Medellín in Colombia. It emphasizes how, in order to be effective, disaster risk reduction has to be driven locally and must include the involvement of communities at risk as well as local governments. It also has to be integrated into development and land use management. But the paper emphasizes how these key local processes need support from higher levels of government and, very often, inter-municipal cooperation. Political or administrative boundaries seldom coincide with the areas where risk reduction needs to be planned and implemented. The paper also includes some discussion of innovations in national systems and funds to support local disaster risk reduction.

ABSTRACT The combination of receivers of Global Satellite Navigation Systems (GNSS) and the kinematic positioning technique in real time (RTK) to construction machines allowed the increase of agility, precision, accuracy … ABSTRACT The combination of receivers of Global Satellite Navigation Systems (GNSS) and the kinematic positioning technique in real time (RTK) to construction machines allowed the increase of agility, precision, accuracy and productivity of earth moving, paving machines and compression. Machine control systems using GNSS-RTK allow full control of the position of the machine blades, allowing the operator to worry only about the direction. These systems are composed, in addition to GNSS receivers, UHF radio, angular sensors, rotation sensors, and on-board computer, which is responsible for compiling the information sent by each component, for eliminating errors arising from machine movements and for determining the position of the blade. However, it was noted that Brazilian companies are resistant to technology. One of the hypotheses that encouraged the study was that the adoption of technology required major changes in the way the company works and in human resources. In this way the present work sought to demonstrate the difference between conventional and satellite-assisted techniques, their gains and pre -requirements necessary for its operation, elucidates the problem faced by users.

Wallace. Tomamos como punto de partida la síntesis física elaborada por Sto. Tomás de Aquino en el De principiis naturae, y buscamos aplicar el modelo hilemórfico en la comprensión de los fenómenos naturales estudiados por las ciencias. De este modo discutimos la condición substancial de los átomos y sus componentes, atendiendo sobre todo a dos notas: su forma de ser y la estabilidad de esta condición, y rescatamos la utilidad de una consideración análoga de la causalidad material.

La hibridación entre especies cercanas permite indagar sobre los mecanismos de aislamiento reproductivo y especiación. Estudiamos una zona de contacto entre dos montañeritos andinos (Atlapetes flaviceps y A. fuscoolivaceus) que … La hibridación entre especies cercanas permite indagar sobre los mecanismos de aislamiento reproductivo y especiación. Estudiamos una zona de contacto entre dos montañeritos andinos (Atlapetes flaviceps y A. fuscoolivaceus) que se reemplazan geográficamente en la vertiente oriental de la Cordillera Central, para examinar los patrones de variación fenotípica y el comportamiento territorial. Analizamos la variación en siete caracteres de coloración del plumaje usando fotografías georreferenciadas de individuos vivos (n = 111) y de especímenes (n = 40) para construir clinas fenotípicas basadas en dos índices de hibridación: patrón facial y coloración corporal. Para evaluar la discriminación del canto como posible mecanismo de aislamiento reproductivo precigótico, realizamos experimentos de playback en territorios de A. flaviceps arriba de Ibagué, Tolima. El análisis de clinas reveló una zona de hibridación centrada cerca a Inzá, Cauca (2,55°N), con anchos contrastantes: la clina de coloración corporal mostró una transición gradual (73 km), mientras que la clina de patrones faciales exhibió una transición más abrupta (12 km). Esta diferencia probablemente refleja una selección fuerte en los patrones de la cara y cabeza, que es donde ambas especies más difieren, aunque también a una mayor densidad de datos para el índice de hibridación facial. Los experimentos de playback mostraron que las parejas territoriales de A. flaviceps no discriminan entre cantos locales y heteroespecíficos, aunque responden por más tiempo a cantos locales (diferencia promedio = 2,3 min, P < 0.05). Nuestros resultados sugieren una zona de hibridación inédita entre A. flaviceps y A. fuscoolivaceus, en donde se presenta una transición suave entre fenotipos puros a lo largo del centro de la Cordillera Central. Eso es probablemente facilitado por el débil aislamiento comportamental. Este trabajo de grado representa el primer paso para investigaciones a largo plazo sobre la variación fenotípica, genómica, especiación y ecología de la hibridación entre Atlapetes andinos.
Fuel quality is a determining factor for the sustainable development of nations, directly influencing energy efficiency, vehicle performance, public health, and environmental conservation. This study aims to analyze, using a … Fuel quality is a determining factor for the sustainable development of nations, directly influencing energy efficiency, vehicle performance, public health, and environmental conservation. This study aims to analyze, using a quantitative approach, public perceptions of fuel quality in Ecuador, comparing the results with international benchmarks, in order to identify regulatory gaps and propose guidelines for improvement. Through structured surveys conducted with drivers across different regions of the country, aspects such as vehicle efficiency, economic impact, engine performance, pollutant emissions, and the need for energy policy reforms were evaluated. The results show that respondents believe that low-quality fuel affects their finances and the durability of their vehicles, while a large number of them demand urgent improvement policies. The discussion compares these results with international practices, highlighting the superiority of regulatory frameworks such as those applied in the European Union or the United States, which impose strict standards for octane, sulfur content, and additives. This analysis concludes that Ecuador faces a significant gap with respect to advanced energy models, which negatively impacts technical efficiency, social costs, and the environment.
According to the population projections, the city of Santa Ana has recorded 398,351 inhabitants in 2023, with a Per-Capita Production of 1.10 Kg. inhabitant/d. By the year 2040, it is … According to the population projections, the city of Santa Ana has recorded 398,351 inhabitants in 2023, with a Per-Capita Production of 1.10 Kg. inhabitant/d. By the year 2040, it is estimated that there will be 454,734 inhabitants. with a PCP of 1.3 kg per person/d. Santa Ana´s solid waste management has a waste separation plant, which classifies residues as combustible and non-combustible. The combustible material is destined for an incineration plant to produce cement and the non-combustible material is destined for a sanitary landfill. The Integral Solid Waste Management suggests, in its management hierarchy, that before disposing or treating waste, it must be used for recycling and then treat the excess. By incinerating waste, the recycling potential is reduced, thus generating the allocation of new materials from natural resources. The suggested management strategy establishes that of the 592.41 Ton/d, 201.39 Ton/d must be recycled; 343.54 Ton/d is organic matter that can be treated by anaerobic digestion generating 185.51 Tn/d of residue known as digestate, successively composting can be applied generating 46.38 Tn/d of compost. Anaerobic digestion can generate an average of 36.8 MW of electricity.

Esta investigación evalúa el impacto del uso de geotextiles tejidos de alto módulo en la infraestructura vial, mediante un análisis comparativo- cuantitativo aplicado a tramos de la parroquia El Valle, … Esta investigación evalúa el impacto del uso de geotextiles tejidos de alto módulo en la infraestructura vial, mediante un análisis comparativo- cuantitativo aplicado a tramos de la parroquia El Valle, Ecuador, seleccionados según la capacidad portante CBR. La problemática considera la necesidad de mejorar la eficiencia estructural, reducir costos y disminuir la dependencia de materiales pétreos no renovables, cuya extracción y transporte afectan la sostenibilidad de proyectos viales. A partir de los diseños definitivos viales provistos por el Gobierno Parroquial, se evaluaron tres alternativas: el diseño original de pavimento que incorpora suelo estabilizado con cemento, un diseño tradicional sin refuerzo y un tercer diseño que considera refuerzo con geotextil tejido de alto módulo. La metodología combinó el procedimiento de diseño AASHTO-93 con un enfoque complementario que incorpora el Traffic Benefit Ratio (TBR). Este enfoque permite calcular el beneficio estructural del geotextil mediante la comparación de la capacidad de soporte entre secciones reforzadas y no reforzadas, ajustando el número estructural requerido y estimando la reducción posible en los espesores de capa granular, en función del refuerzo incorporado. Los resultados mostraron un incremento promedio del 20% en el número estructural para TBR=4. Una reducción de hasta el 25.59% en espesores granulares y un ahorro económico del 3% respecto al diseño tradicional en la vía con menor CBR. En comparación con el diseño original estabilizado, el modelo reforzado presento un ahorro del 7% en costos directos. Estos hallazgos confirman la viabilidad del geotextil tejido como alternativa técnica y sustentable para optimizar estructuras viales.

Methods In a cross-sectional survey, 305 residents from 30 asbestos-affected neighborhoods completed questionnaires on asbestos knowledge and practices. Environmental samples (roofing, dust, and water) were analyzed for asbestos fibers. Results Asbestos-cement roofing was present in 87.5% of homes. While 55.8% recognized asbestos hazards, 52% routinely disturbed asbestos materials, and informal disposal was common. Socially embedded practices, such as repurposing asbestos sheets and improper disposal were common. Asbestos fibers were found in 90% of dust samples and 85% of rainwater samples. Conclusions Residential asbestos exposure remains a major health risk in these communities. Mitigation requires not only education but also improved policies for safe removal and replacement of asbestos materials.
El cambio climático, sumado al aumento sostenido del consumo de energía en la edificación, plantea retos críticos para la sostenibilidad arquitectónica, particularmente en climas mediterráneos donde la radiación solar durante … El cambio climático, sumado al aumento sostenido del consumo de energía en la edificación, plantea retos críticos para la sostenibilidad arquitectónica, particularmente en climas mediterráneos donde la radiación solar durante el verano resulta especialmente intensa. Este trabajo evalúa la hipótesis de que la biomímesis, combinada con herramientas paramétricas e inteligencia artificial (IA), puede superar las limitaciones del diseño pasivo tradicional al mejorar la eficiencia energética y la respuesta climática de las envolventes. El propósito de esta investigación es verificar dicha hipótesis mediante el estudio de tres configuraciones geométricas bioinspiradas: Delaunay, Voronoi y Metaball. Estos modelos se desarrollaron utilizando principios biomiméticos, simulaciones digitales y algoritmos de IA, aplicados a un prisma arquitectónico representativo situado en la Comunidad de Madrid, con el fin de evaluar su capacidad para reducir la incidencia de la radiación solar durante los meses estivales. Los patrones se generaron en Rhinoceros 8/Grasshopper, mientras que la evaluación climática se llevó a cabo mediante Ladybug Tools 1.5.0 (Radiance/Daysim). Las variantes geométricas se optimizaron mediante el algoritmo genético multiobjetivo NSGA-II, programado en Python 3.10 (DEAP) e integrado vía GhPython. Los objetivos específicos fueron (i) disminuir la radiación solar recibida y (ii) limitar la complejidad material, con el fin de asegurar la viabilidad constructiva de las propuestas. Los resultados indican que este enfoque no solo logra una significativa mitigación de la radiación solar, sino que también ofrece soluciones innovadoras y adaptables que integran funcionalidad, eficiencia energética y estética. Estas estrategias ofrecen un potencial considerable para redefinir el diseño arquitectónico sostenible, sentando las bases para nuevas aplicaciones prácticas que permitan reducir el consumo energético y responder a los retos climáticos contemporáneos. Este estudio subraya el impacto de la convergencia entre biomímesis, tecnología paramétrica e inteligencia artificial, abriendo perspectivas para el desarrollo de modelos arquitectónicos más resilientes y adaptados a las demandas energéticas globales.

Marco Teórico: Se analizaron conceptos sobre potencial forestal, biodiversidad arbórea amazónica, impacto de la minería aurífera y superposición legal de derechos mineros y forestales, destacando la importancia de integrar la valoración económica de los ecosistemas en decisiones de planificación territorial. Método: Se aplicó un enfoque interdisciplinario que combinó inventarios forestales en parcelas de 0,1 ha, valoración económica basada en precios oficiales de madera, y análisis normativo de la legislación minera y forestal vigente. Se calcularon índices de diversidad y el Índice de Valor de Importancia (IVI) para evaluar la estructura arbórea. Resultados y Discusión: Los bosques evaluados mantienen una riqueza arbórea considerable pese a la actividad minera, dominada por especies de bajo valor comercial (75%-86%). Solo entre el 1% y 4% de las especies tienen alto valor económico. Iriartea deltoidea y Euterpe precatoria sobresalieron como especies resilientes. Legalmente, se identificó la necesidad de fortalecer los instrumentos de gestión forestal en concesiones mineras para promover la sostenibilidad. Implicaciones de la Investigación: El estudio demuestra que aún existe un potencial forestal significativo en áreas mineras que, si es manejado adecuadamente, puede contribuir a la conservación de la biodiversidad amazónica y a la mitigación del cambio climático. Originalidad/Valor: Esta investigación aporta evidencia empírica clave para diseñar políticas de ordenamiento territorial y manejo forestal sostenible en contextos de minería activa, resaltando la importancia estratégica de los bosques amazónicos intervenidos.
El impacto humano en las condiciones ambientales de las zonas urbanas se traduce en un aumento de la contaminación y una disminución de la calidad de vida de los habitantes. … El impacto humano en las condiciones ambientales de las zonas urbanas se traduce en un aumento de la contaminación y una disminución de la calidad de vida de los habitantes. Para comprender cómo cambian las condiciones ambientales en el tiempo y el espacio, y su relación con la actividad humana, es esencial contar con equipos que puedan monitorear estas condiciones en tiempo real. Para abordar esta necesidad se desarrolló el dispositivo Estación de Monitoreo Geo Ambiental (EMGA) y su plataforma de gestión, almacenamiento, visualización y descarga de datos. Este dispositivo, diseñado y programado en el Laboratorio de Paleomagnetismo y Magnetismo de Rocas del Instituto de Geociencias de la Universidad Nacional Autónoma de México (UNAM), permite realizar un monitoreo ambiental en tiempo real en entornos urbanos, facilitando el análisis del impacto de las actividades humanas en las condiciones ambientales. Las EMGA son capaces de medir en tiempo real ocho variables diferentes mediante sensores de bajo costo: calidad del aire (partículas suspendidas PM2.5, PM1.0 y PM10), temperatura (ºC), presión atmosférica, humedad relativa (%), ruido ambiental (μPa) y variaciones en la intensidad del campo magnético terrestre (μT). Los datos recopilados por los sensores se envían en tiempo real a la plataforma de visualización cada cuatro minutos y pueden ser consultados desde cualquier computadora o dispositivo móvil. La información obtenida por las EMGA permite desarrollar y adaptar redes de monitoreo ambiental de bajo costo, lo que facilita el análisis de las condiciones ambientales en zonas urbanas a lo largo del tiempo y el espacio.
