In Peru, grasslands monitoring is essential to support public policies related to the identification, recovery and management of livestock systems. In this study, therefore, we evaluated the spatial dynamics of grasslands in Pomacochas and Ventilla micro-watersheds (Amazonas, NW Peru). To do this, we used Landsat 5, 7 and 8 images and vegetation indices (normalized difference vegetation index (NDVI), enhanced vegetation index (EVI) and soil adjusted vegetation index (SAVI). The data were processed in Google Earth Engine (GEE) platform for 1990, 2000, 2010 and 2020 through random forest (RF) classification reaching accuracies above 85%. The application of RF in GEE allowed surface mapping of grasslands with pressures higher than 85%. Interestingly, our results reported the increase of grasslands in both Pomacochas (from 2457.03 ha to 3659.37 ha) and Ventilla (from 1932.38 ha to 4056.26 ha...

Research on graphic organizers and reading comprehension has taken up new reins in the knowledge about the reader's mental processes, but it has been avoided to understand the levels in the reading process. The importance of organizers often focuses on the power they demonstrate to allow the reader to analyze and map ideas, especially concept maps and mind maps. In this study, we propose to determine the effects of graphic organizers on text comprehension at the school stage. The study is quantitative of quasi-experimental design. It was developed in 42 students from the primary level of Callao, Peru. The results allow concluding that the graphic organizers improved the comprehension of texts in general. The evidences remit significant differences with scores compared at the literal level. The results of inferential understanding presented data that revealed improvement, although it was ...

Este caso de estudio describe cómo una empresa peruana dedicada a la consultoría en TI consiguió acortar de manera significativa el tiempo que tomaba consolidar sus liquidaciones. Al inicio, el proceso era lento y generaba constantes retrabajos. Esto se debía, principalmente, a que la información estaba repartida en múltiples fuentes, a que muchas verificaciones se hacían manualmente y fuera de tiempo, a que se producían errores o duplicidades al cargar datos y a que no existía un seguimiento claro del avance de cada liquidación. Para enfrentar estas dificultades, se desarrolló una intervención basada en cuatro ejes. En primer lugar, se ordenó el flujo completo del proceso y se definieron reglas claras para cada método de liquidación (a consumo, constante y por asignación de personal). En segundo lugar, se fortaleció la calidad de los datos mediante campos obligatorios y...

Infectious bursal disease is a pathology of viral origin that affects poultry, causing a high mortality rate. Existing vaccines face the problem of the appearance of new strains, so searches are made for molecules with potential binding affinity to viral proteins. Withania somnifera extract is involved in the replication of infectious bursitis virus, but the possible mechanism of action is not well understood. The aim of this study was to identify, through in silico methods, the phytoconstituents of W. somnifera with binding affinity to the active site of viral protein 1 (VP1) of infectious bursal disease virus. Molecular docking assays were performed between VP1 and 27 phytoconstituents described in W. somnifera. The binding energy data obtained were analysed with the Kruskal-Wallis test and Dunn’s test (p<0.05). The results showed that the compounds somniferin, withanolide A, with...
