In oviparous marine fishes, the hyperosmotic induction of sperm motility in seawater (SW) is well established, however, the potential function of ion channels in the maintenance of post activated spermatozoon swimming performance remains largely unknown. [...]

En este artículo, presentamos resultados preliminares de un proyecto de investigación en curso en el cual analizamos la desigualdad social en Argentina para el período 1990-2019. Como punto de partida, proponemos el abordaje de las desigualdades sociales como un fenómeno que es relacional, multidimensional, procesual y multiescalar. [...]

Decidir cómo continuar la enseñanza se ha identificado como la destreza más difícil de entre las tres que configuran la competencia de mirar profesionalmente el pensamiento matemático del estudiante. [...]
To decide on how to on a teaching-learning situation has been identified as the most difficult of the three skills that make up the competence of noticing student's mathematical understanding. In this study 95 pre-service primary school teachers solved a task in which they had to propose a learning objective and activities to support this development of the understanding the meaning of fraction as part-whole using as a reference a hypothetical learning trajectory.

Este artículo diseña un sistema de control para el problema de seguimiento de trayectorias de un vehículo quadrotor con una carga suspendida desconocida. La presencia de esta carga desconocida incrementa considerablemente la complejidad del problema, y su oscilación actúa como una perturbación incierta que afecta a la dinámica propia del vehículo. [...]
This article designs a control system for the trajectory tracking problem of a quadrotor vehicle with an unknown suspended load. The presence of this unknown load considerably increases the complexity of the problem while its oscillation acts as an unknown perturbation that affects the dynamics of the vehicle. [...]
