ABSTRACT The estimation of evapotranspiration (ET) and crop water requirements are crucial for the proper management and allocation of water resources in terms of quantity, quality, and timeliness. Therefore, remote sensing estimation of ET using the SEBAL algorithm (Surface Energy Balance Algorithm for Land) can provide spatio-temporal, non-punctual data, unlike traditional calculations relying on the nearest meteorological station. This research analyzed ET using SEBAL, based on ten Landsat 8 satellite images processed with a program developed in the Model Builder of ArcGis® version 10.2. The analysis was conducted during the vegetative period of starchy corn from May to October 2016. Validation of the results happened with a drainage lysimeter installed in a monitoring plot. Additionally, the statistical indices - such as percentage relative error (PRE) (0,09), root mean square error (RMSE) (0,30), R2 (0,92), and Nash-Sutcliffe efficiency (NASH) (0,91) - indicated a good correlation of ET for starchy corn in the central highlands of Peru. The ET identified at ten monitoring points ranged from 1,05 to 7,79 mm d-1.

ABSTRACT Proper waste management is a major worldwide concern; waste is disposed of directly into the environment, affecting water, soil and air quality. The development and production of green energy sources is strongly encouraged in modern society. The aim of this study, in accordance with Sustainable Development Goals (SDGs) 1, 2 and 7 of the 2030 Agenda of the UN, is to combine the correct disposal of animal waste with the generation of energy to mitigate the energy insecurity of families in an extremely vulnerable semi-arid region in the north-east of the country using biodigesters. To this end, a conceptual proposal was drawn up for a low-cost, easy-to-maintain and easy-to-use biodigester. A small-scale prototype was used to assess its operation by evaluating the main factors that affect biogas production (pH, temperature and the biomass properties: total solids, fixed solids, volatile solids, concentration of volatile fatty acids and C/N ratio). Evaluation of the test prototype gave satisfactory results that corroborate other studies and make it possible to propose an economically viable and efficient full-scale biodigester for biogas production. concern environment water quality society study SDGs (SDGs 1 203 UN semiarid semi arid northeast north east biodigesters end lowcost, lowcost low cost, cost low-cost easytomaintain easy maintain easytouse use smallscale small scale pH, pH (pH properties solids CN C N ratio. ratio . ratio) fullscale full 20

ABSTRACT Biochar can promote crop production and soil quality. However, its characteristics depend on the waste used in its production and its effects may vary according to the species being cultivated and the management adopted. The aim of this study was to evaluate the application of biochar from animal waste on soil quality and the agronomic characteristics of the cowpea. An experiment was set up to test three types of biochar (bovine-BB, swine-SB and poultry-BP), with added fertiliser (BBF, SBF and BPF) and two control treatments, including the addition of calcium magnesium oxide (CT) and calcium magnesium oxide with fertiliser (CTF), giving a total of eight treatments with four replications. There was a respective increase of up to 102.94%, 1048%, 1560% and 360.22% in stem diameter, number of pods, number of grains per pod and stem dry matter from adding the biochar. The poultry biochar increased each of the above parameters even with no added fertiliser. There was no difference in basal soil respiration or β-glucosidase enzyme activity, whereas organic carbon (TOC), total nitrogen (TN), microbial carbon and soil labile carbon were greater with biochar. BBF gave the highest TOC content (24.40 g kg-1), while BP and BPF increased TN by around 61%. The application of biochar + fertiliser contributed to an average reduction of 56% in the soil metabolic quotient. Poultry biochar favoured both the agronomic characteristics of the cowpea and soil quality, while bovine biochar showed more marked results with the addition of fertiliser.

Abstract Introduction. Coffee (Coffea spp.) is the second most traded product globally and is cultivated in over eighty countries. Its cultivation is complex because it belongs to an ecosystem where abiotic and biotic factors interact under various agronomic management conditions. To understand the development of the coffee plant and its influence on the sensory quality of the final product, it is necessary to explore the intricate interactions between the coffee plant and the native microorganisms within the crop environment. Objective. To describe the role of the coffee soil microbiota, specially bacteria and fungi, and how they may contribute to the final quality of the beverage. Development. Soil is one of the most diverse and least studied ecosystems, where crucial ecological functions for plant growth and development take place. Identifying soil microbial components and their interactions with other organisms is important from an agronomic perspective. The soil microbiota can enhance plant physiology; thus, this review aims to connect how the sensory attributes of coffee beverage can be positively influenced by soil microbiota. Articles from ScienceDirect, Scopus, Web of Science, and Google Scholar from 2011 to 2023 were reviewed. The data show the diversity of plant growth-promoting rhizobacteria (PGPR), nitrogen-fixing bacteria (NFB), and arbuscular mycorrhizal fungi (AMF) associated with coffee cultivation. Additionally, microbial compounds play an important role in the formation of sensory attributes and are related to the coffee cup quality. Conclusion. The microbial diversity of soil and on the fruit can synthesize or degrade compounds that affect the sensory profile of the coffee beverage, which could have implications for sustainability and quality.

Resumen Introducción. El café (Coffea spp.) es el segundo producto más comercializado a nivel mundial y cultivado en más de ochenta países. Su cultivo es complejo por pertenecer a un ecosistema donde factores abióticos y bióticos tienen dinámicas bajo diferentes condiciones de manejo agronómico. Para comprender el desarrollo de la planta y su influencia en la calidad sensorial del producto, hay que conocer la intrincada interacción entre la planta del café y los microorganismos autóctonos del cultivo. Objetivo. Describir el rol de la microbiota edáfica del café, bacterias y hongos, y cómo puede contribuir en la calidad final de la bebida. Desarrollo. El suelo es uno de los ecosistemas más diversos y menos estudiados, en el cual se desarrollan funciones ecológicas importantes para el crecimiento y desarrollo de las plantas. La identificación de los componentes microbianos del suelo y sus interacciones con otros organismos, son importantes desde el punto de vista agronómico. La microbiota edáfica puede favorecer la fisiología de la planta y de esta manera, se realiza la presente recopilación de información que busca asociar cómo los atributos sensoriales de la bebida de café pueden ser beneficiados por la microbiota del suelo. Se revisaron artículos de ScienceDirect, Scopus, Web of Science y Google Scholar, entre el 2011 y 2023. Los datos muestran la diversidad de rizobacterias promotoras del crecimiento vegetal (RPCV), bacterias fijadoras de nitrógeno (BFN) y hongos formadores de micorrizas arbusculares (HMA) asociados con el cultivo de café. También existen compuestos microbianos que juegan un papel importante en la formación de atributos sensoriales y están relacionados con la calidad en taza del café. Conclusión. La diversidad microbiana del suelo y fruto puede sintetizar o degradar compuestos que influyen en el perfil sensorial de la bebida, lo cual podría tener implicaciones para la sostenibilidad y calidad.

ABSTRACT One of the most important aspects for sustainable aquaculture is the proper management of feed, for which the best strategy is the implementation of automatic feeders that allow optimizing feed rations and optimizing productive performance. The present study evaluated the impact of automatic feeding on soil quality in the cultivation of Litopenaeus vannamei in three experimental pools in a period of three months; where were evaluated the amount of organic matter, organic carbon, pH, nitrogen and the carbon-nitrogen ratio (C/N) to evaluate if there are differences in the feeding and lung-type zones. In the final analyzes no statistical differences (p ≥ 0.05) were observed in the parameters between the feeding areas and between the pools. These results demonstrate that automatic feeding does not cause changes in soil quality in the cultivation of L. vannamei.

RESUMEN Uno de los aspectos más importantes para una acuacultura sustentable es el manejo adecuado del alimento, para lo cual la mejor estrategia es la implementación de alimentadores automáticos que permiten optimizar las raciones de alimento y optimizar el rendimiento productivo. El presente estudio evaluó el impacto de la alimentación automática sobre la calidad del suelo en el cultivo de Litopenaeus vannamei en tres piscinas experimentales en un periodo de tres meses; se evaluaron las cantidades de materia orgánica, carbono orgánico, pH, nitrógeno y la relación carbono-nitrógeno (C/N) para discernir si existen diferencias en los puntos de alimentación y de tipo pulmón. En los análisis finales no se observaron diferencias estadísticas (p ≥ 0.05) entre los puntosde alimentación y entre las piscinas. Estos resultados demuestran que la alimentación automática no provoca cambios en la calidad del suelo en el cultivo de L. vannamei.

Summary: Currently, agricultural activity is constantly threatened by the effects of climate change and radical expression of environmental factors as irregular rainfall distribution responsible for water availability and deficit. These factors generate water stress in productive systems, whose negative effect is reflected on morphological, physiological and biochemical aspects of vegetative growth. The use of biostimulants arises as a strategy to counteract this impact, improving crop efficiency in the use of resources and generating responses, as metabolite production, among other substances that mitigate the effects of oxidative stress. In this context, waxes, hydrogen peroxide (H2O2), salicylic acid (SA) and ALGAENZIMSMR were used on raspberry plants subjected to moderate water stress (-0. 8 MPa) to evaluate the fruit response in aspects of vegetative growth, physiological and biochemical quality. For the establishment, a completely randomized design was used with 5 treatments: Green Cover as 5 mL L-1, H2O2 10-4 M, salicylic acid 0.27 mM, ALGAENZIMSMR 7.5 mL L-1 and the control with 50% recovery of the transpired volume as well as water potential similar to the rest of plants and 4 replicates. The results showed that waxes, SA and algal extract increased the photosynthetic rate; the four treatments increased root length; waxes increased root height; and H2O2 increased root biomass. Compared to the control, higher levels of vitamin C and anthocyanins were produced in fruits - a very important aspect due to the functionality of these compounds in human health. Therefore, the use of these biostimulants are a very useful tool for crop management in environments with water restriction.

Resumen: En la actualidad la actividad agrícola se ve amenazada constantemente por los efectos del cambio climático y la expresión radical de los factores ambientales, como la irregularidad en la distribución pluvial responsable de la disponibilidad del agua y déficit, que genera estrés hídrico en los sistemas productivos, cuyo efecto negativo se refleja en aspectos de crecimiento vegetativo, morfológicos, fisiológicos y bioquímicos. El uso de bioestimulantes surge como estrategia para contrarrestar este impacto, mejorando la eficiencia de los cultivos en el uso de los recursos y generar respuestas, como la producción de metabolitos entre otras sustancias, que mitigan los efectos del estrés oxidativo. Bajo este contexto se planteó el uso de ceras, peróxido de hidrogeno (H2O2), ácido salicílico (AS) y algaenzims, sobre plantas de frambuesa sometidas a estrés hídrico moderado (-0.8 MPa) con el objetivo de evaluar la respuesta en aspectos de crecimiento vegetativo, fisiológicos y calidad bioquímica de frutos, para el establecimiento se empleó un diseño completamente al azar con 5 tratamientos: greencover as® 5 mL L-1, H2O2 10-4 M, ácido salicílico 0.27 mM, algaenzims® 7.5 mL L-1 y el control con recuperación del 50% del volumen transpirado y con potencial hídrico similar al resto de plantas y 4 repeticiones. Como resultados se obtuvo que las ceras, AS y el extracto de algas incrementaron la tasa fotosintética, los cuatro tratamientos aumentaron la longitud de raíces, las ceras la altura, y el H2O2 la biomasa de raíz. Por otro lado, en comparación con el control, se produjeron mayores niveles de vitamina C y antocianinas en frutos, un aspecto muy importante por la funcionalidad de estos compuestos en la salud humana. Por lo tanto, el uso de estos bioestimulantes se puede visualizar como una herramienta de gran utilidad para el manejo de cultivos en ambientes con restricción de agua.

Summary: The tomato (Solanum lycopersicum L.), due to its high demand and production, is the most important vegetable in the world, coupled with this, it is a functional food due to its antioxidant content. This crop is produced under a protected system with a synthetic inorganic fertilization source, which increases production costs. It is important to find an alternative source of fertilization and agronomic management that increases yields and improves the commercial and nutraceutical quality of this crop. The aim of the study was to verify the effect on the commercial quality and bioactive compounds of tomato, with doses of solarized bovine manure and the number of stems under a protected system, as well as evaluate the effect of organic fertilization on the soil. The research was carried out during the spring-summer 2021 cycle. Eight treatments (4×2 factorial) were obtained from the combination of four fertilization doses (0, 40, 60 Mg ha-1 of solarized manure and chemical fertilizer [Urea (46-0-0) and MAP (11-52-0)] with two numbers of stems (one and two stems) per plant. The commercial quality was superior organoleptically with the treatment of 60 Mg ha-1 and with a single stem being higher than 4.8 °Brix. The highest yield was obtained with the dose of 60 Mg ha-1 of bovine manure being statistically similar to chemical fertilization. The content of bioactive compounds (lycopene and antioxidant capacity) increased by 36% with the effect of the interaction of 60 Mg ha-1 of manure and a stem compared to the chemical treatment. The content of MO, NO3 -, NH4 + and PO4 -3 in the soil increased with the doses of manure, which reflects one of the benefits of using this fertilizer organic.

Specialized mental health management is recommended to be included in the comprehensive care of patients and former patients with Hansen's disease.

Abstract In retail markets, analysis of perceived value in purchasing processes has been a topic of special interest as it focuses on perception of benefits beyond the product itself. In the face of such interest, an exhaustive bibliographical review was performed regarding its concept and components applied to retail dealers. The methodology is quantitative and cross-sectional, with a descriptive and explanative analysis through structural equation models to analyze the effect of dimensions in perceived value in the dependent variable of intent to purchase. Applied surveys on 390 recurring customers of retail dealers in Bogota. The results revealed that: functional value does have a positive effect on intent to purchase; and there is a relation between functional and symbolic value of purchase. The implications of management in the context of marketing are further discussed, focusing on functional value of a purchase. Actions related to quality, communication, employee training and customer service are recommended. These findings contribute to the literature on consumer behavior within the context of consumption by comparing functional and symbolic value.

Resumen En el ámbito del comercio minorista, el análisis del valor percibido en el proceso de compra ha sido objeto de especial interés por enfocarse en la percepción de beneficios que van más allá del producto en sí. Ante tal interés, se realizó una exhaustiva revisión bibliográfica sobre su concepto y componentes aplicado a establecimientos minoristas. La metodología es cuantitativa y transversal, con un análisis descriptivo y explicativo a través de modelos de ecuaciones estructurales para analizar el efecto de las dimensiones del valor percibido en la variable dependiente de la intención de compra. Se aplicaron encuestas a 390 a clientes habituales de comercios minoristas en Bogotá. Los resultados revelaron que el valor funcional tiene un efecto positivo en la intención de compra; y existe una relación entre el valor funcional y el valor simbólico de la compra. Se discuten las implicaciones de la gestión en el ámbito del marketing, centrándose en el valor funcional de la compra.

Resumo Dentro do âmbito do comercio de retalho, a análise do valor percebido no processo de compra tem sido objeto de interesse especial por se focalizar em a percepção de benefícios que vão mais longe do produto direito. Com esse interesse, fez-se uma revisão exaustiva da literatura de seu conceito e componentes aplicados aos estabelecimentos de retalho. A metodologia é quantitativa e transversal, com uma análise descritiva e explicativa por meio de modelos de equações estruturares para analisar o efeito das dimensões do valor percebido na variável dependente da intenção de compra. Fizeram-se pesquisas em 390 clientes usuais de lojas de retalho em Bogotá. Os resultados revelaram que: o valor funcional tem um efeito positivo na intenção de compra; e existe uma relação entre o valor funcional e o valor simbólico da compra. Discutem-se as implicações da gestão no âmbito do marketing, focalizando-se no valor funcional da compra. Sugerem-se ações relacionadas à qualidade, comunicação, capacitação dos empregados y serviço ao cliente. Os resultados contribuem à literatura com relação ao comportamento do consumidor no contexto do consumo, ao comparar o valor funcional e o valor simbólico.

Abstract: Smart Grids have revolutionized the electricity industry by enabling more efficient control and monitoring of the electricity supply, with a key component being smart meters (SM). These collect information on demand, energy, and harmonic distortion, among others, which must be stored and managed efficiently in a metering data management system (MDMS). The MDMS must ensure that a complete set of data is obtained for use in algorithms to ensure the reliability and quality of the power supply. To address the challenge of management the big data generated by SM, short, medium, and long-term measurement forecasting techniques have been proposed, highlighting the use of artificial intelligence such as Artificial Neural Networks (ANN) and Deep Learning (DL) methods due to their ability to adapt to different input and output variables with various time horizons. In addition, the influence of the diversity of Information and Communication Technologies (ICT) on the update time and data storage in the MDMS is highlighted. In this sense, this work aims to identify which ANN or DL architecture(s) could be more suitable for enterprise, survey, or research applications, demonstrating favorable performance metrics in different scenarios of sampling frequency and typical data update times in Smart Grids. This is relevant due to the need for MDMS to perform multivariate and multi-pass predictions in the short term to complete the information until the information is available or updated.

Resumen: Las Redes Eléctricas Inteligentes de Distribución (REID) han revolucionado la industria eléctrica al permitir un control y monitoreo más eficiente del suministro eléctrico, con un componente clave siendo los medidores inteligentes (SM). Estos recopilan información sobre la demanda, energía, distorsión armónica, entre otros, que deben ser almacenados y gestionados eficientemente en un sistema de gestión de datos de medición (MDMS). El MDMS debe garantizar la obtención de un conjunto completo de datos para su uso en algoritmos que aseguren la confiabilidad y calidad del suministro eléctrico. Para abordar el desafío de gestionar la gran cantidad de datos generados por los SM, se han propuesto diferentes técnicas de predicción de mediciones a corto, mediano y largo plazo, destacando el uso de inteligencia artificial como las Redes Neuronales Artificiales (ANN) y métodos de Aprendizaje Profundo (DL) debido a su capacidad de adaptación a diferentes variables de entrada y salida con diversos horizontes temporales. Además, se destaca la influencia de la diversidad de Tecnologías de la Información y Comunicación (TIC) en el tiempo de actualización y almacenamiento de datos en un MDMS. En este sentido, este trabajo tiene como objetivo identificar qué arquitectura o arquitecturas de ANN o DL podrían ser más adecuadas para aplicaciones en empresas, estudios o investigaciones, demostrando métricas de rendimiento favorables en diferentes escenarios de frecuencia de muestreo y tiempos de actualización de datos típicos en un REID. Esto es relevante debido a la necesidad del MDMS de realizar predicciones multivariables y multipaso a corto plazo para completar la información, hasta que la misma esté disponible o se actualice.

Abstract: The integration of electric mobility is real nowadays. Government policies increasingly focus on encouraging the use of electric vehicles (EVs); particularly, replacing conventional public mobility with electric buses. An adequate energy management of electric bus systems must optimize resource usage, and extend the lifespan of transport units and charging stations, while providing quality service to users. The performance of the EV transport system depends on various deterministic and stochastic variables that need to be accurately simulated to analyze its behavior as closely as possible to real conditions. In this study, a model for the energy analysis of EVs has been implemented, by using the software SUMO (Simulation of Urban Mobility) and applying it to public transport routes in Quito, Ecuador. Through the executed simulations, energy consumption has been estimated and, a sensitivity analysis of the energy consumption of electric bus units to the variations in relevant parameters in the energy management of public transport systems, has been carried out. The impact of certain parameters on energy consumption has been verified, by indicating a significant decrease in the autonomy of EVs on the simulated route under very similar to reality operating conditions. For study case, autonomy reduction of electric bus is around 27% in comparison with manufacturer's specifications. The analysis of energy performance under various traffic scenarios will allow future optimizations of the electric public transport system operation, since traffic levels, variable traffic flow, and pronounced changes in terrain elevation, are considered.

Resumen: La integración de la movilidad eléctrica es una realidad en el mundo actual, las políticas gubernamentales se enfocan cada vez más en incentivar el uso de vehículos eléctricos (VE) particulares, pero, principalmente en reemplazar la movilidad pública convencional por el uso de buses eléctricos. Una adecuada gestión energética de los sistemas de buses eléctricos debe optimizar el uso de recursos, prolongando la vida útil de las unidades de transporte, estaciones de carga y brindando siempre un servicio de calidad a sus usuarios. El desempeño del sistema de transporte mediante VE depende de diversas variables determinísticas y estocásticas que necesitan ser debidamente simuladas a fin de analizar su comportamiento, lo más cercano a las condiciones reales. En el presente trabajo, mediante la aplicación del software SUMO (Simulation of Urban Mobility), se ha implementado un modelo para el análisis energético de VE y se lo ha aplicado en rutas de transporte público en Quito-Ecuador. A partir de las simulaciones realizadas se ha estimado el consumo energético y se ha efectuado un análisis de sensibilidad del consumo energético de las unidades de buses eléctricos ante variaciones de parámetros relevantes en la gestión energética de sistemas de transporte público. Para el caso de estudio se comprueba la reducción de la autonomía del bus eléctrico en 27% de acuerdo con la información del fabricante. El análisis del desempeño energético realizado bajo diversos escenarios de tráfico permitirá en futuros trabajos optimizar la operación de los sistemas de transporte público eléctrico, considerando niveles de tráfico, flujo vehicular variable y pronunciados desniveles en su relieve.
