Teachers of Latino students reflect on the implementation of a mathematical task

Teachers in two multi-grade study groups in elementary schools with large populations of Latino students reflect on the implementation of an open-ended mathematical task. IN this research, interviews and study group discussions provide the teachers’ reflections on the implementation of the task and on their practices in general that create learning environments for their Latino students. Multiple categories representing the teacher reflections were developed and our focus is on those practices that teachers consider effective and specific factors that impact practice. The design of this study proved to be especially useful in promoting teacher reflective conversation

Phenolic profile changes of grapevine leaves infected with Erysiphe necator

Powdery mildew in grapevine is caused by Erysiphe necator and its control requires many chemical treatments. Numerous efforts are being made to improve disease management to achieve crop sustainability goals. The exogenous induction of plant immune responses is one of the most encouraging strategies currently being developed. The objective of this research was to analyse differences in phenolic compound concentrations in E. necator-infected leaves of two varieties of Vitis vinifera, Tempranillo and Tempranillo Blanco, using ultra performance liquid chromatography coupled with mass spectrometry. To understand the susceptibility of the varieties, in vitro assays using whole leaves were done.This work was funded by the Spanish Ministry of Economy and Competitivity (Ministerio de Economía y Competitividad, MINECO) under project BIO2017-86375-R.Peer reviewe

Determinación y validación de las cuencas hidrográficas de la Isla de Gran Canaria (Islas Canarias, España)

En el presente trabajo se plantea una metodología para la obtención y validación de dos elementos fundamentales en cualquier aplicación SIG hidrológica, que son las cuencas hidrográficas y los cursos de aguas o redes de drenaje (thalwegs). Como bien es sabido en la cartografía oficial a cualquier escala se definen los thalwegs, pero no así las cuencas hidrográficas, las cuales se pueden llegar a definir con la ayuda de un MDE (Modelo Digital de Elevaciones). A través de procesos automáticos en un SIG, se definen las cuencas hidrográficas. Se ha de evaluar la precisión de las mismas en función del paso de malla elegido en el MDE. Y de igual forma, se validan los thalwegs de la cartografía, ya que estos pueden poseer errores de posicionamiento.Peer ReviewedPostprint (published version
