The effects of organic and conventional crop systems on chemical composition, antioxidant activity and functional properties were evaluated in white and dark chia (Salvia hispanica L.) seeds. The organic system reduced the total protein content, and increased the total carbohydrates but did not change polyunsaturated fatty acids, total phenolic or flavonoids. Organic white chia seeds showed the best techno-functional properties. The antioxidant capacity of chia extracts varied in relation to the chemical complexity and differential rate kinetics of different assays. Extractable total phenolic acids and antioxidant capacity were better in organic white chia seeds. In this first approach, we have demonstrated that the organic white chia seed has a better total antioxidant capacity measured by direct quencher approaches than its conventionally-grown counterpart. To summarize, we conclude th...

The removal of heavy metals from wastewater is an environmental challenge which demands the use of environmentally friendly materials that promote a circular economy. This study aimed to apply a novel composite of an activated nanoclay/hydrocolloid in the removal of heavy metals from wastewater. A composite blended under pressure was prepared with spray-dried hydrocolloid derived from Nostoc sphaericum algae and activated nanoclay in an acid medium and 1M NaCl. The composite and components were analyzed through infrared (IR), X-ray (XR), ζ potential, cation exchange capacity (CEC), particle size, and SEM images. The composite was subjected to the adsorption of heavy metals (Pb, As, Zn, and Cd) at pH 4.5 and the removal percentage, kinetics, and adsorption isotherms were evaluated. It was observed that the activated nanoclay and the composite that presented a particle size of around 400 ...

El presente informe de ingeniería intitulado “Biodiversidad y Desarrollo en la Región San Martín”, tiene como objetivo de recopilar propuestas para el desarrollo regional, en base al uso sostenible y conservación de la diversidad biológica. Las conclusiones obtenidas nos indican que el estudio de la biodiversidad se caracteriza porque está constituido por aspectos de composición, estructura y función de los ecosistemas. Existe una urgencia de conocer la naturaleza y magnitud de la biodiversidad con la finalidad de estudiarlo desde el punto de vista científico. La biodiversidad nos brinda muchos servicios ambientales para la humanidad, como la regulación del clima, fijación de CO2, polinización y el control de la erosión dependen del normal funcionamiento de los ecosistemas. La biodiversidad también representa valores culturales y religiosos. Toda esta riqueza, está sie...

(ANTECEDENTES) La búsqueda de arquitecturas eficientes y adaptables ha sido constante en el desarrollo de software, destacando la Arquitectura Orientada a Servicios (SOA) por su capacidad para integrar aplicaciones mediante servicios independientes y reutilizables. Con el avance tecnológico y la necesidad de sistemas escalables y ágiles, han surgido los microservicios, que dividen aplicaciones en partes más pequeñas con contextos y funcionalidades propias, promoviendo modularidad y facilidad de desarrollo. Comparar SOA y microservicios es esencial para entender sus diferencias, ventajas y desventajas en entornos ágiles, y para elegir el enfoque adecuado según los objetivos del proyecto. (OBJETIVOS) El objetivo es analizar comparativamente SOA y microservicios en entornos de desarrollo ágil, identificando sus contribuciones, similitudes, diferencias, problemas y soluciones. (MÉTO...

The implementation of efficient grazing technologies in high mountain cattle ranches in the department of Nariño (Colombia) increases the sustainability of these production systems and promotes the conservation of the landscape design. With the objective of evaluating the dry matter intake of F1 (Kiwi-cross x Holstein) and Holstein cattle biotypes, present in hillside areas of the Nariño mountain, a preliminary trial of individual consumption of ryegrass (Lolium perenne) was carried out in Pasto (Nariño-Colombia) with the gauging technique, and the results were compared with models reported in the literature. The data were analyzed as a completely randomized design, with repeated measures over time. Intake per gauging was higher (p<0.05) in Holstein cows, with respect to F1 cows (12.74 vs. 9.69 kg/dry-matter/day), but per unit live weight was similar (p>0.05). On the other hand,...

Pleurocollybia cibaria Singer es una seta comestible nativa de Cusco que goza de mucha popularidad. Se expende en la fiesta de “Q’oncha Raymi” y en los mercados de la ciudad durante la época de lluvia. Su composición nutricional aún es poco conocida y no se ha profundizado sobre su composición de minerales, vitaminas y alguna propiedad funcional, cómo su actividad antioxidante. Las setas tienen la capacidad de acumular trazas de metales, resultando en un peligro potencial para la salud de los consumidores. Por estas razones, se reportó la composición nutricional, la concentración de metales pesados y la actividad antioxidante in vitro de P. cibaria Singer. Respecto a la composición nutricional, la muestra fresca contenía una alta proporción de humedad (79.48%) y deshidratada, un alto contenido de carbohidratos (44.44%), proteínas (23.83%), fibra (12.73%) y de los minera...

Wildfires are part of the socio-ecological history of fire-prone territories such as Mediterranean Europe. However, during the las decades, the increasing severity of wildfires due to socio-environmental factors have revealed the vulnerability of these socio-ecological systems (SESs) in the face of global environmental change, revealing the need to increase resilience in the face of wildfires. In contrast to the well stablished wildfire suppression policies, which in the long term have resulted in fuel build-up and larger wildfires, increasing literature suggest focussing on wildfire prevention. Among the potential measures, fostering extensive grazing is on strategy that is gaining visibility in fire-prone territories such as Spain, where the activity has been traditionally carried out but currently is showing an abandonment tendency. Widespread research has been done on the ecological ...

La salinización del suelo es un creciente problema ambiental que reduce el crecimiento y la capacidad fotosintética de las especies vegetales, siendo un factor determinante en la composición, distribución geográfica y diversidad de las comunidades de plantas, principalmente en ecosistemas áridos y semiáridos. Ante la salinización del suelo, las plantas reducen el impacto negativo del estrés salino sobre su desempeño biológico a través de cambios morfológicos, fisiológicos y bioquímicos. En zonas áridas como el bosque seco norperuano, la sequía y altas temperaturas pueden favorecer la acumulación de sales en el suelo, lo que podría alterar la distribución y abundancia de las especies habitantes según su tolerancia. En este ecosistema co-ocurren los arbustos predominantes Beautempsia aviceniifolia y Capparicordis crotonoides (Capparaceae), que bajo el supuesto de que e...

This study was carried out in the Loretillo forest concession (No. 17-TAM/C-OPB-A-026-07), located in the Las Piedras River conservation corridor in Tambopata, Madre de Dios. The main objective was to conduct an inventory of wildlife species, focusing on their use as bioindicators of the ecosystems within the concession. The study considered variables such as the species composition of flora, birds, and mammals, as well as the ecosystem services they provide (ESS). To this end, eight Permanent Sampling Plots (PSPs) and linear transects were established, distributed across two predominant ecosystem types: alluvial flooded forest (B-ai) and lowland hill forest (B-cb). The analyses included alpha and beta diversity indices, ecological importance values (IVI), and parameters related to threatened species. The B-ai ecosystem was found to have greater biological richness and diversity. T...
