Syzygium cumini o Jamun es un árbol tropical de hoja perenne de la familia de plantas ornamentales Myrtaceae. El material vegetal (hojas) de Syzygium cumini (Jamun) se colectó en el Instituto de Ciencia y Tecnología Aplicadas (IAST) de la Universidad de Guyana, campus de Turkeyen. Las hojas se secaron en estufa a 50-60 ºC durante 72 h. Se calculó el contenido de humedad. Las hojas secas se trituraron y se extrajeron en etanol, metanol, acetato de etilo y disolventes de cloroformo, sucesivamente. Se recogieron los extractos y se evaporó el disolvente en rotavapor. Se añadió el disolvente respectivo al extracto líquido semisólido viscoso para completar el volumen deseado de solución de extracto. Los microorganismos (Escherichia coli, Staphylococcus aureus y Candida albicans) se obtuvieron de GPHC, Georgetown, Guyana. La actividad antioxidante, antimicrobiana y antifúngica de los diferentes extractos se evaluó mediante métodos descritos en la literatura. El poder antioxidante máximo y mínimo fue exhibido por los extractos de metanol y cloroformo, respectivamente. Se encontró que los extractos de cloroformo y acetato de etilo tenían la actividad antibacteriana máxima y mínima contra Escherichia coli, Staphylococcus aureus, así como la actividad antifúngica contra Candida albicans, respectivamente, por el método de difusión por disco. El análisis fitoquímico de los extractos de hojas de Syzygium cumini reveló la presencia de carbohidratos, terpenoides, proteínas, aminoácidos y flavonoides.

“…Some scholars have focused on the exploration of magnitude time series [3][4][5]. There have been studies on the time interval sequence of earthquake occurrence, most of which have analyzed the probability distribution of the earthquake time interval [6][7][8][9][10]. There have also been studies on the prediction of time intervals.…”

Based on the catalog data of earthquakes with Ms ≥ 2.5 in the Longmenshan fault zone from January 2012 to September 2021, we establish an earthquake time interval series grouped by earthquake magnitude and then use the SARIMA model to predict the series in different periods. By analyzing the fitting effect of the models, the optimal model parameters of different magnitude sequences and the corresponding period values are obtained. Among them, the adjusted R2 values of each model with Ms ≥ 2.5 and Ms ≥ 3.0 sequences are more than 0.86, up to 0.911; the short-time prediction effects are good, and the values of predicted RMSE are 10.686 and 8.800. The prediction results of the models show that the overall trend of the subsequent earthquake time interval in the Longmenshan fault zone is stable, and the prediction results of the Ms ≥ 3.0 sequence have a weak fluctuating growth trend; that is, the number of earthquakes with the Ms ≥ 3.0 in this area will decrease slightly, and the seismicity will decrease in a period of time. The analysis results and method can provide a scientific basis for earthquake risk management and a feasible way to predict earthquake occurrence times.
