The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space group, experimental conditions and quality measures.

Para realizar esta caracterizacion se analizaron los datos de precipitacion de 35 estaciones meteorologicas representativas, de una serie temporal de 44 anos; desde 1971 hasta 2014. Debido a que la serie de datos no era homogenea se empleo una tecnica de aproximacion de datos, aplicando regresion lineal. Se emplearon varios parametros, entre los cuales se tienen: la magnitud, la intensidad y la frecuencia de la sequia meteorologica. Se calculo el indice de sequia pluviometrica, y se hizo una relacion entre los anos con eventos secos y anos con presencia del fenomeno El Nino o La Nina. Los resultados obtenidos a traves de este estudio fueron los siguientes: los meses que presentan mayor ocurrencia de eventos secos de mayor a menor son agosto, ju...

The robotic kit was constructed for educational purposes with a cost of $75. The structural analysis was continued thanks to the support of the CIC and de Computer Science School, achieving a very nice, attractive and functional design allowing the robot be used in different kind of learning projects.

Building on this base, the research community has bridged the gap from college to pre-college education, even elementary school [2]. However, little work has been done to engage students in out-of-school settings, particularly for those students from populations under-represented in the sciences. We present a theoretically-grounded model of university-community partnership [3] that engages university students and children in a collective enterprise that has the potential to improve the participation and education of all. We document the impact of these programs on: university participants who learn about education, the community and even some science; children in the community who learn about science, the nature of science and develop their identities and attitudes towards science; and, shifts in institutional practice which may allow these programs to be sustained, or not.
