Sancho García, Amanda (Date of defense: 2012-11-16)
The predictability of beach inundation is mainly related to wave runup and most of the formulations that have been developed focus on the hydrodynamics, disregarding the morphological changes caused during storms. For these ...
Galbán Malagón, Cristóbal (Date of defense: 2013-09-20)
Humanity is currently using more than 200000 synthetic organic compounds in many industrial, agricultural and domestic applications. Many of these chemicals reach the environment and have a harmful effect on ecosystems and ...
Sbragaglia, Valerio (Date of defense: 2015-07-20)
Nephrops norvegicus is an important fishery resource for Europe. Its rhythmic burrowing behavior is strictly related to catchability. Here I studied such behavior under laboratory conditions. I investigated the combined ...
Díez Rilova, Margarita (Date of defense: 2012-05-07)
En nuestra sociedad los derivados del petróleo son la fuente principal de energía. Los accidentes con hidrocarburos han protagonizado episodios de contaminación trágicos para la biosfera del océano. Se analizan algunos ...
