  • IoT based system for monitoring dissolved oxygen and temperature in fish larviculture

    Revista Brasileirade Ciencias Agrarias, 2023
    : Aquaculture is carried out in controlled environments to guarantee the health, growth, and survival of aquatic species, so it is essential to monitor water quality parameters. We designed and implemented a system based on the Internet of Things for monitoring dissolved oxygen and temperature in Amazonian fish larviculture. We based the design of the architecture on four layers: data acquisition, communication, cloud server and application. We carried out the experimental tests with the data collected by the system during seven days of culture of larvae of the species Piaractus brachypomus (paco) in the aquaculture center “La Cachuela”. The values obtained for dissolved oxygen varied between 7.43 ± 0.04 and 7.83 ± 0.02 mg L -1 ; regarding the water temperature, it fluctuated between 19.59 ± 0.45 and 25.45 ± 0.11 °C. We concluded that the system developed for monitoring dissolved oxygen and water temperature displays data obtained in real time, in both cases the values are within the tolerable ranges for the cultivation of this species.

    Eai Endorsed Transactions on Energy Web, 2023
    INTRODUCTION: Air pollution in urban areas becomes a severe challenge to global health; exposure to polluting gases can lead to different diseases and even human mortality. In this sense, monitoring the concentration of polluting gases such as carbon monoxide and methane is important.
 OBJECTIVES: This document focuses on developing a Remotely Piloted Aircraft System (RPAS) to monitor the concentration of carbon monoxide and methane at different altitudes. 
 METHODS: This includes a Parrot AR Drone 2.0, where the measurement prototype was mounted. The data was transmitted and reception at a ground control station through an application programmed in LabVIEW 15.0.
 RESULTS: The experimental measurements showed that the concentration of carbon monoxide remains almost unchanged regardless of variations in altitude. In contrast, methane concentration reduces linearly with the increase in height with respect to ground level in Puerto Maldonado.
 CONCLUSION: We implemented an RPAS to monitor in real time, record data in a control station and analyze the concentration of carbon monoxide and methane in the South Eastern Peruvian Amazon.
  • High Andean Woody Plants, between Nursing and Competition Effects in a High Andean Polylepis Forests

    Iop Conference Series Earth and Environmental Science, 2022
    The diversity of Plants in the Andes is a complex stochastic network, this diversity is characterized by being distributed in three main families: Asteraceae, Poaceae and Rosaceae. The first two are the most diverse and have the Gynoxis and Chusquea genera respectively as the most dominant woody individuals in the last altitudinal floors above 3200 m. a. s. l. However, the Rosaceae family has less richness, it includes the genus Polylepis, present in the last tree line limit above 4300 m.a.s.l. This is the case of mono-specific forests of Polylepis rodolfo-vasquezii, a species highly threatened by anthropogenic impacts such as logging, burning, and llama-sheep farming. These forests are relict and generate a nurse effect, which allows the existence of important diversity such as Gynoxis nitida, Miconia latifolia, Bomarea dulcis and Displostephium rupestri and Brachyotum rostratum. However, the impacts generate complex plants diversity responses, where the nurse effect can become into a competition effect, especially with Gynoxis nítida, which can take advantage of the ecological niche to promote the increase in abundance of its young individuals against those of P. rodolfo-vasquezii, which is reduced by anthropic activities.

    E. E. Belito, E. C. Alvarez-Montalván, C. J. Alvarez-Orellana, R. I. Laredo, S. Manrique-León, et al.
    Journal of Physics Conference Series, 2021
    Many forest species of the Peruvian Andes are considered exceptional for having innumerable powers, such is the case of the calorific power product of the chemical composition of the species. This study was carried out in the Department of Huancavelica, Izcuchaca District, the analysis of samples was carried out at the National University of Central Peru and the National University of Agraria la Molina, where ASTM Standards were used to obtain data. The species that presented the highest calorific value was Caesalpinia spinosa with 4658.25 kcal / kg, since within its chemical composition it presented a greater amount of extractables and lignin, while the Vachellia macracantha and Tecoma stans species obtained 4422.05 and 4077.1 kcal / kg respectively. However, the three species studied prove to have an excellent calorific value due they are above 4000 kcal / kg.
  • Optimization and Modeling of the process in the extraction of humidity from banana (Musa paradisiaca L.) in an indirect solar dryer, in the southwest of the Peruvian Amazon

    Introducción: Actualmente se pierde aproximadamente entre 15 y 45% de los productos cosechados, existe diversidad de tecnologías postcosecha para la preservación de alimentos perecederos. El propósito de la investigación fue optimizar y modelar el proceso de deshidratado de Musa paradisiaca L. a través de un secador solar artesanal. Para el deshidratado se obtuvieron 10 kg de muestra de plátano verde en el mercado local por semana, se realizaron cortes en forma longitudinal de 0.45±0.05cm para colocar en cada una de las bandejas del deshidratador solar con peso promedio de 1178.03 g por día, durante 15 días, diariamente se tomó la masa inicial al producto fresco con una balanza analítica, se pesó en tres intervalos, entre las 8:30am – 5:00pm, con la finalidad de determinar la variación de sus masas. El resultado indica que existe relación significativa entre las variables con un nivel de confianza del 95.0 %. La variación explicada del modelo es 99.4683 % de la variabilidad en humedad pérdida en función de las variables independientes. La confiabilidad del modelo para describir el comportamiento del secador solar y el estado final del producto se restringe a ciertas variables tales como la humedad del producto, la temperatura, la humedad relativa del aire interior, sobre las cuales se puede tener certeza a partir del procedimiento de validación realizado.
  • Growth and survivorship of Vetiveria zizanioides in degraded soil by gold-mining in the Peruvian Amazon

    Journal of Degraded and Mining Lands Management, 2021
    In the Peruvian Amazon, large area of primary forest have been deforested by Artisanal and small-scale gold mining (ASGM). Vetiveria zizanioides (Poaceae) is considered an excellent plant for the ecological restoration of degraded lands. The present study aimed to analyze the growth and survivorship of V. zizanioides in degraded soils by gold-mining in the Peruvian Amazon (Madre de Dios). The experiment was conducted under greenhouse conditions, and it followed a randomized complete block design with four treatments (substrates). The substrates were sand (mining), sand+pebbles (mining), forest soil, and amended soil. We evaluated the survivorship, shoot, tiller, and biomass production of V. zizanioides for two months. Univariate analysis of variance was used to detect differences among treatments. Fifteen days after experiment establishment, V. zizanioides survivorship was significantly higher in ASGM substrate 2 (sand+pebbles) than in other substrates, following the order of ASGM substrate 1 (sand) > forest soil > amended soil. However, at the end of the experiment, we did not find a significant difference on survivorship in subsequent assessments, and the total biomass per plant was lower in mining substrates than in non-mining substrates. The total biomass was significantly higher in amended soil than in other substrates, with yields between 1.7 and 3.6 times more biomass in amended substrate than in mine substrates. The soil substrate type significantly affected the survivorship, number of shoots, and biomass of V. zizanioides. The research results can provide a reference for remediation of degraded soils by gold-mining in the Peruvian Amazon.
