La presente investigación se desarrolló en la Universidad Privada del Norte en la facultad de Ingeniería con los estudiantes del curso de Calculo 1 en el año 2016. Cuenta entre los estudiantes de cálculo un total de 400 de los cuales para la siguiente investigación se eligieron 2 grupos a conveniencia de 40 estudiantes cada uno, Para la investigación realizada se tomó un grupo de control y un grupo experimental durante 12 sesiones, siendo estos evaluados de igual manera al finalizar cada sesión. El problema a investigar: ¿Es Maple 17 una herramienta didáctica que permite mejorar el rendimiento académico del curso de cálculo 1 en los estudiantes de Ingeniería de la Universidad Privada del Norte, Cajamarca 2016?,para ello se planteó la siguiente hipótesis: La aplicación de maple 17 como herramienta didáctica mejora el rendimiento académico de los estudiantes de cálculo ...

The achievements obtained after the systematic review carried out are shown, in which the characteristics of the studies of the life phases of pavements focused on cracking and care will be identified, and the consensus reached. To achieve this, the Redalyc, Web of Science, Scopus and Scielo databases were reviewed, which resulted in 10 articles that covered the criteria of the subject. Theoretically, most of the works use the rule-based theory. In order to fully understand and address the problems of roof cracks and maintenance-oriented life cycle, it is recommended to develop studies using various samples and a database, where a review procedure is carried out to verify the basic information according to the subject. And as for the assessment, it is given according to national and international research sources where they are compared on certain variables and factors to be considered. ...

The purpose of the research work was to evaluate the predominance of 2 types of organic liquid foliar fertilizer and 3 doses, in the quality of Cedrela odorata L seedlings. An Entirely Random Design was applied with a 2x3 factorial arrangement and 5 repetitions; the components under analysis were: element A: AFLF and AFLH, and component B: 50, 100 and 150 mL/20 L of water, generating 6 treatments plus a control; 525 seedlings were installed and evaluated over 5 months, after which the highest seedling elevation (19.70 cm) occurred with T5 (150 mL AFLF/20 L water) and the lowest elevation (18, 76 cm) with T1 (50 mL AFLF/20 L water), with high quality seedlings; the largest diameter (8.32 mm) was obtained with T4 (100 mL of AFLH/20 L water) and the smallest (7.41 mm) in T0, with high quality seedlings; show high quality of height/diameter interaction or solidity index; the seedlings of the...

Throughout the years in which a pavement is in service, it is exposed to climatic actions and traffic that wear out its useful life, as well as its quality of mechanical characteristics, as well as functional, causing various failures and types of failures to exist. clothing on flexible pavements; Therefore, using technological option tools has become essential for their respective evaluations. Aim. Perform an analysis of existing failure assessment technology tools in flexible pavement surfaces. Type of research. The research presents a qualitative approach, which is supported by obtaining reference information on technological tools for evaluating failures in flexible pavements. Method. It was carried out through bibliographic reviews of scientific articles; Therefore, for this study, the use of databases such as: REDALYC, SCIENCEDIRECT, DIALNET, SCIELO; whose applied criteria were in ...
