La investigación tuvo como objetivo determinar la relación entre las políticas de ciencia, tecnología e innovación tecnológica (CTI) y los objetivos del desarrollo sostenible (ODS) del Perú en el Sistema Nacional de Ciencia y Tecnología, para lo cual se utilizó el diseño descriptivo. La conclusión principal fue que sí existe una relación significativa con un r=0.526 y un p=0.000 por lo tanto, un cambio ya sea para positivo o para negativo en la política de ciencia, tecnología e innovación tecnológica ocasionará un cambio en los objetivos del desarrollo sostenible.

Currently, great importance has been given to the study of external morphology, especially in fish, when it is used as a means of identifying hybrids. This paper considers a LASSO model based on the truss protocol to compare morphological covarion patterns between specimens of Colossoma macropomum and the hybrid C. macropomum (♀) x P. orinoquensis (♂). In this study, 25 specimens of C. macropomum and 20 specimens of the hybrid C. macropomum (♀) x P. orinoquensis (♂), respectively, were analyzed. The method "Truss protocol" or "trusses" Strauss and Bookstein (1982) was used. LASSO model achieved to reduce the mean squared error. The final model obtained contains only seven covariates. LASSO model fitted on the morphological covariation patterns between specimens of C. macropomum and the hybrid C. macropomum (♀) x P. orinoquensis (♂) showed a good fit and allowed to correctly c...

This research was carried out in the district of Luya, province of Chachapoyas, Amazonas, with the objective of evaluating the optimal dose of gibberellic acid (Full Gib) in the induction of sprouting of potato tubers (Solanum tuberosum L.) Yungay variety. A Completely Randomized Design (CRD) with two factors three replications and seven treatments was used. Minitat 17 statistical software, ANOVA, and the Tukey mean comparison test at 5% were used for data analysis. The treatments were: Nothing was applied (T1), 7.5 mL of Full Gib in 20 L of water, for 15 min (T2), 7.5 mL of Full Gib in 20 L of water, for 20 min (T3), 10 mL of full Gib in 20 L of water, for 15 min (T4), 10 mL of full Gib in 20 L of water, for 20 min (T5), 12. 5 mL of full Gib in 20 L of water, for 15 min (T6), 12.5 mL of full Gib in 20 L of water, for 20 min (T7). The variables evaluated were: Sprouting percentage, numbe...
