Los gases de efecto invernadero, entre ellos el CO2 generan una serie de cambios climáticos debido a la permanencia de este en la atmosfera por largos periodos de tiempo; de ese modo, la vegetación juega un rol fundamental en la captura de carbono. El presente estudio tiene como objetivo determinar la influencia del material particulado sedimentable en el secuestro de carbono en la vegetación de la ciudad de Lima. La metodología considera seis etapas: planificación de gabinete, implementación de las parcelas de muestreo, evaluación de la contaminación atmosférica por material particulado sedimentable (MPS) empleando a la vegetación como bio-indicador, determinación del estado fisiológico de la vegetación arbórea, determinación de la captura de carbono en vegetación (Cv) y estimación de stocks de carbono. Los resultados obtenidos señalan que el MPS ejerce influencia sign...

El objetivo del presente trabajo fue elaborar unas galletas de chocolate enriquecidas con una mezcla de bazo de res y sangre de pollo, para prevenir la anemia. El bazo de res y sangre de pollo fueron secados a temperaturas entre 50 ° C-60 ° C, hasta alcanzar una humedad del 2,6%. Se obtuvieron tres formulaciones (F1, F2 y F3), donde la F1 (código 123) contenía 5 g: 15 g; F2 (código 567) 15 g: 5 g y F3 (código 248) con 10 g y 10 g, de harina de sangre de pollo y bazo de res respectivamente, con un enriquecimiento total del 13,1%. Se elaboraron galletas de chocolate endulzadas con yacón y enriquecidas con estas formulaciones y se evaluaron sensorialmente por un panel de consumidores entre 25 y 70 años. Se aplicó la prueba de Friedman, mostrándose que la F2 obtuvo mayor preferencia para los atributos de sabor y textura con diferencia significativa (p <0.05) y una aceptación de...

Based on the need to make accurate decisions in the face of the COVID-19 pandemic in Peru, pandemic in Peru, specifically for the recovery of the tourism sector. For this purpose, a characterization of the behavior of the pandemic was carried out in the first three months of its development, based on the analysis of trends and the determination of the effective reproduction number (Rt) from statistical-mathematical methods. A variant of the SIR mathematical model was applied to forecast the possible evolution of the pandemic. This model was adjusted with the GlobalSearch optimization strategy of the MATLAB software. His solution used the MATLAB function ode23tb, which uses a combined Runge-Kutta algorithm with a trapezoidal rule algorithm. With the application of the Kaizen strategy as a means of continuous improvement, a set of actions were proposed that could be carried out today and t...
