Determinar la eficiencia del Reactor de Esponjas Colgante de Flujo Descendente (DHS) a escala piloto como tratamiento aerobio secundario, posterior al tratamiento del Reactor Anaerobio de Flujo Ascendente (UASB) del agua residual doméstica de los centros poblados el Ángel y el Milagro en el distrito del Rímac. Determinar el efecto del sistema DHS en los parámetros físico-químicos (Temperatura, pH, Turbiedad, Oxígeno Disuelto y Conductividad) del efluente del reactor UASB y efluente del reactor DHS. Determinar el efecto del sistema DHS en el parámetro microbiológico de Coliformes termotolerantes del efluente del reactor UASB y efluente del reactor DHS. Determinar la eficiencia del DHS a lo largo de su periodo de funcionamiento (Arranque y Experimental) mediante un análisis estadístico, comparando con el ECA categoría 3 uso de riego y los LMP para efluentes de PTAR de agua vige...

Objective: To determine the clinical adverse events related to the use of femoral and radial artery access in patients who underwent interventional cardiology procedures in the Hospital Nacional Hipólito Unanue from 2015 to 2017. Materials and methods: A comparative, retrospective, observational and analytical study was conducted with a total of 151 medical records of patients who had clinical adverse events. Medical record review was used as data collection technique, and a data collection sheet designed by the researcher was used as instrument. The R software was used for the analysis. Results: Out of 151 cardiac catheterizations, 51.66 % were performed by a femoral artery access and 48.34 % by a radial artery access. The average age of the patients was 59.6 ± 11.3 years, out of which 39.73 % ranged between 60 and 70 years, and 73.50 % of the patients were males. The most frequent co...
