Methodological study of the cryoconservation processes in miocroalgae

[EN]Two cryopreservation methods, controlled cooling and encapsulation/vitrification, were studied in order to find an appropriate protocol to maintain microalgae cultures by exposing them to ultra-low temperatures (cryogenics). This study has shown that the most efficient cryopreserving method is the use of cryoprotectants, being Glycerol and DMSO the best options for this procedure, and dismissing the encapsulation/vitrification method due to the low effectiveness, which results in a low post-thaw viability rate and a higher demanding of labour and consumables.

Integración de aerogeneradores de baja potencia en la red de baja tensión

[EN] The current energy model is unsustainable economically, environmentally and socially forcing develop renewable technologies that modify the concept to the responsible use. The use of low-power wind turbines has generally been limited to isolated which has slowed their development systems. The study addresses this technological niche to deepen their study of integration of electricity on a low voltage network. For this first wind potential with Homer software is evaluated. Various scenarios are simulated in "The IEEE European Test Low Voltage Feeder" network using the software OpenDSS widely used in studies of Generation Distributed by EPRI (Electric Power Research Institute).
