Background: Virtual teaching has become an essential component of nursing education today, but its impact on practical courses remains unexplored. There is a need to understand how the quality of virtual teaching influences both academic performance and student satisfaction. Objective: This study aims to explore how nursing students’ satisfaction and academic performance in practical courses relate to the quality of virtual teaching in a Peruvian university in 2023. Methods: A descriptive cross-sectional correlational study was conducted by surveying 125 nursing students in northern Peru from March to May 2023. The data were collected using the Online Education Scale and Academic Satisfaction Scale. Academic performance was assessed through documentary analysis of the students’ general averages, and Kendall’s tau-b test was used to assess the relationship. Additionally, Pearson’s...

Using Moringa oleifera (Moringa oleifera Lam.) seed as a biocoagulant to enhance surface water's physical and chemical quality was the goal of this study. The methodology applied for the generation of experimental data was through the use of the Jar Test equipment, in a dose of 40 mg/L to 140 mg/L, then a fast mixing of 100 rpm for 1 minute and a slow mixing of 40 rpm for 10 minutes was performed, and sedimentation was left for 5 to 30 minutes, with 5 minutes intervals between each dose. The results show that an optimal biocoagulant dose of 100 mg/L at 20 minutes produced a turbidity reduction effectiveness of 97.06%. Hardness fell by 12% of its starting value, conductivity and total dissolved solids increased dramatically, and there was a 92.3% reduction in perceived colour, which showed that the use of Moringa seeds as a coagulant had a favourable effect on reducing the concentration o...
