One of the most important radiative properties of aerosols is their optical thickness (AOD), which is closely linked to the total burden of atmospheric aerosols. On the contrary, we do avail of long time series of sunshine ...
Ben Mbarek, Wael (Fecha de defensa: 2018-11-20)
This work is framed in the general context of the synthesis and characterization of Mn or Ca based alloys, which are subsequently applied in degradation processes of azo dyes used in the textile industries. The alloys were ...
Wederni, Asma (Fecha de defensa: 2021-11-26)
Shape memory alloys witch exhibit magnetically induced phase transformations at room temperatures are the most interesting for magnetic cooling applications. Heusler type alloys (both stoichiometric and non-stoichiometric) ...
Pujol Company, M. Dolors (Fecha de defensa: 2013-04-16)
Coastal zones are governed by physical forces originating from tidal currents, waves, winds and night convection, amongst others, and are characterized by the presence of canopy meadows. This thesis studies the hydrodynamic ...
García Rodríguez, Santiago (Fecha de defensa: 2019-06-28)
This thesis investigates the impact response of novel laminates made with “thin-plies” as well as proposes a toughening method to improve their impact tolerance. To this purpose, we devised a wide experimental campaign ...
