Uno : revista de didáctica de las matemáticas
Resumen basado en el de la publicaciónSe presenta una secuencia de enseñanza para estudiantes de 11 a 13 años, que busca propiciar la construcción de significado del objeto geométrico punto medio. Se pretende que ellos produzcan la definición de punto medio y la usen para justificar acciones y aserciones realizadas al solucionar problemas.Biblioteca de Educación del Ministerio de Educación y Formación Profesional; Calle San Agustín, 5 - 3 Planta; 28014 Madrid; Tel. +34917748000; [email protected]
Enseñanza de las ciencias : revista de investigación y experiencias didácticas
Resumen basado en el de la publicaciónTítulo, resumen y palabras clave también en inglésSe presentan los resultados de una investigación realizada en torno a la interpretación de la condicional y al uso que de ella hace un grupo de estudiantes para profesor de matemáticas en el marco de un curso de geometría plana. Se analizan los resultados de dos cuestionarios aplicados, uno al inicio del curso y otro al final, con el objetivo de comparar su interpretación y uso de la condicional. Los cambios estarían generados por la implementación, a lo largo del semestre, de algunas estrategias didácticas tendientes a favorecer el acercamiento a los correspondientes desde la matemática.ES

Comparing the pozzolanic activity of aerial lime mortars made with metakaolin and fluid catalytic cracking catalyst residue: A petrographic and physical-mechanical study
We investigated the viability of a fluid catalytic cracking catalyst residue (FC3R) as an alternative sustainable
pozzolanic additive in aerial lime mortars. The pozzolanic activity of FC3R was compared to that of
metakaolin (MK) by chemical-mineralogical, petrographic and physical investigations. The FC3R showed
lower pozzolanic activity than MK when added to aerial lime mortars, owed to the size of FC3R particles
that generate less hydrated phases and give place to lower mechanical resistances in mortars. We also
demonstrated that FC3R is not a compatible material for use in repair mortars, due to the formation of
the harmful soluble salt ettringiteSpanish Ministry of Economy, Industry and Competitiveness under the program ‘‘Juan de la Cierva-Incorporación” (2015 call)Spanish Spanish Ministry of Economy, Industry and Competitiveness under research project MAT2016-75889-

Measurement results of the MALTA monolithic pixel detector
MALTA is a full scale monolithic pixel detector implemented in TowerJazz 180 nm CMOS technology. The small pixel electrode allowed for the implementation of a fast, low noise and low power front-end, which is sensitive to the charge released by ionizing radiation in a 20–25 μm deep depleted region. The novel asynchronous matrix architecture is designed to ensure low power consumption and high rate capability. Such features make MALTA a possible candidate for the outer layer of ATLAS Inner Tracker (ITk) upgrade. Unirradiated and irradiated MALTA sensors have been extensively tested in laboratory and with high energy particle beams. Results of this measurements campaign are shown, and the further improvements that are being implemented in the next versions of the chip are discussed
