Several specific strategies proposed by many authors are seen as techniques, related to the implementation of our strategy. The results have been applied in the Cuban mathematics teachers training.

The vagal ganglion was located next to hyperplasic lymphoid nodes in para-tracheal and tracheal-bronchial levels,… (More)
The effect of early postnatal malnutrition on the responsiveness of the rat prefrontal cortex was studied by determining excitability thresholds and fatigability to direct cortical stimulation. Malnutrition imposed during the period of rapid brain growth caused a significant increase of cortical chronaxie values as well as increased fatigability of direct… (More)
