La presente investigación titulada “Uso de internet en los estudiantes del primer grado de educación secundaria en una institución educativa del callao” tuvo como objetivo establecer el nivel de uso de Internet por estudiantes del primer grado de secundaria para fines académicos. Es una indagación de nivel descriptivo simple, con una muestra de 100 adolescentes donde se aplicó un encuesta, donde el coeficiente de Cronbach obtuvo 0.906 en la validación, y donde se concluyó que a través del uso de internet se eleva el nivel cognitivo y académico permitido mejorar los resultados estudiantiles de forma significativa en los estudiantes ya que los estudiantes del primer grado de secundaria perciben que el uso de internet eleva su nivel cognitivo y académico por lo que tienden a tener logros significativos, con respecto a aquellos estudiantes que no hacen uso de esta red. Por lo ...

Background: Fire danger indexes (FDIs) are used as proxies for fire potential and are often developed for specific locations. For practical purposes, the extrapolation of the underlying calculations into novel locations is common, but it is generally uncertain if the relationships between FDIs and fire potential observed in the environment in which the index was developed are equally relevant in others. For example, although a topographically, ecologically, and climatologically complex country, f ire danger forecasts in Peru use a standard set of nationwide thresholds applied to the Fire Weather Index. In this study, we validate the underlying assumption that weather-fire relationships are spatially uniform within Peru by (1) making cross-regional comparisons of the statistical distributions of four FDIs—Burning Index, Energy Release Component, Fire Weather Index, and Keetch-Byram Drou...

This paper presents the updated list of amphibians and reptiles of Ica. Species are commented, accompanied by distribution maps and identification keys for reptiles and amphibians. Information was collected from scientific collections, scientific articles, governmental wildlife agency reports, and specialized taxonomic database. Additionally, between 2019 and 2020, field surveys were carried out in areas with information gaps. A total of 22 species were found (amphibians 3 and reptiles 19). The new records of reptiles include the Liolaemus evaristoi lizard and the Incaspis tachymenoides snake from Chincha province at 4200 and 3200 m altitude respectively, the Stenocercus ornatissimus lizard and the blind snake Epictia tesselata from Pisco province at 3500 and 2800 m respectively. New amphibian records include Pleurodema marmoratum in Chincha province (3900 m) and Telmatobius rimac in Chi...
