The research determined the relationship between research competencies and learning styles in final-year students of civil engineering of a university, and applied two instruments, the Felder and Soloman learning styles test and the research competencies questionnaire. The population was 146 students, men and women, of the curricular experiences Research Project and Development of the Research Project; with a sample of 25 women and 81 men. It turned out that the level of research skills is high for 58.5% of respondents and the predominant learning styles were moderate active, reflective discreet, sensitive moderate, intuitive discreet, visual very strong, verbal discreet, sequential moderate and global discreet. The Spearman Rho bivariate correlation analysis as a hypothesis test allowed us to conclude that the research competencies are only significantly related to active and reflective...

In this investigation, the effect of sugarcane bagasse ash (SBA) on concrete strength of 210 kg/cm2 is evaluated, partially replacing SBA with cement, in proportions of 20 and 40%. The results showed that the compressive strength of the concrete decreased with increasing ash content, below the design mix. Concrete with 20% SBA had better compressive performance at 7 and 28 days of cure, although both were 59% below standard concrete (control). This suggests not recommending SBA for structural use because of its decreased compressive strength.   Keywords: agro-industrial waste, concrete, sugarcane bagasse.  

El desarrollo de las competencias investigativas es una de las preocupaciones actuales de las universidades, las cuales deben ser atendidas tanto en el desarrollo de habilidades investigativas como en la construcción de instrumentos para su evaluación permanente. El objetivo del presente trabajo ha sido comparar los instrumentos de medición de las competencias investigativas en base a los criterios: dimensiones, tipos de validez, confiabilidad, la muestra, los países y el año en que fueron aplicados. Las fuentes de información consideradas fueron las bases de datos: SCOPUS, EBSCO, PROQUEST, SCIELO y SCIENCEDIRECT. Se seleccionaron trece artículos que cumplieron los criterios de: límite de tiempo entre los años 2010 y 2021; idioma español e inglés; calidad informativa y ámbito universitario. Se determinó que los instrumentos generalmente utilizan en su construcción aspectos ...
