El estudio de investigación propone determinar la relación entre la metodología de enseñanza y el aprendizaje significativo de estadística aplicada a la ingeniería, serie 200, escuela profesional de Ingeniería Agroindustrial – UNSCH, 2018. Planteando la hipótesis de investigación existe relación significativa entre la metodología de enseñanza y el aprendizaje significativo de estadística aplicada a la ingeniería, serie 200, escuela profesional de la Ingeniería Agroindustrial – UNSCH. La metodología utilizada fue tipo básico, nivel descriptivo correlacional, método hipotético deductivo, diseño no experimental, la muestra estuvo constituida por 60 estudiantes de la serie 200 de la escuela profesional de Ingeniería Agroindustrial – UNSCH, el instrumento aplicado fue un cuestionario para recoger los datos de las variables de estudio propuestas en la investigación....

The empirical use of alpaca rennet in the production of artisanal cheeses with cow’s milk is widespread in the high Andean communities of Perú and Bolivia, and has not been scientifically reported. The objective of the present study was to characterize alpaca rennet and evaluate its coagulating activity. Ready-to-use alpaca curds were collected directly from dairies in four neighborhoods of Viscapalca (Huancavelica-Perú, 4003 masl), which were transported under refrigeration and kept frozen at -20°C. The Crude Enzymatic Extract (CEE) was obtained by centrifugation at 560 x g for 10 min at 4°C, from which proteins were determined by Bradford, SDS-PAGE electrophoretic profile, coagulation time and proteolytic activity. The traditional management of alpaca rennet is also described. CEE was found to contain 29.80 to 52.91 µg/ml of protein. The SDS-PAGE electrophoretic profile revealed...

The postharvest quality of strawberry depends on agronomic factors, especially in high Andean areas where climatic conditions influence its development. This study aimed to evaluate the effect of fertigation and substrate type on the postharvest properties of the Chandler variety. A factorial design with eight treatments was used, combining four fertigation levels (0 %, 20 %, 40 %, and 60 %) and two substrate types (agricultural soil and sand). Evaluations of the physical, physicochemical, and functional properties of the fruits were performed in triplicate. The results showed significant differences (p < 0.05) among treatments, highlighting 60% fertigation in sandy substrate, which promoted greater red color intensity (a* = 60.27 ± 0.93), higher fresh weight (12.92 ± 0.64 g), reducing sugars of 1.94 ± 0.01 mg/g, and higher content of bioactive compounds such as phenolics (123.97 Â...
