Biodiverse green roofs in Mediterranean climate. Input and lessons learned from Germany and Switzerland
In the realm of the doctoral program in technologies for sustainability and land restoration, this thesis deepens sustainable and ecological solutions for Mediterranean environment after the German tradition and the Swiss school of green roofs for biodiversity. Specific aims were to: (1) assess the effectiveness of the existing green roofs norms in supporting biodiversity; (2) review methodologies and approaches for the implementation of biodiverse green roofs but also their application for ecological design; (3) identify habitat templates in the Mediterranean ecoregion replicable on green roofs; and (4) investigate the long term vegetation development of unmanaged green roofs in order to g…
Propuesta de monitorización integral de la calidad ambiental del interior de la Iglesia de los Santos Juanes de Valencia
2020
Para la correcta conservación de los bienes de interés cultural (BIC), debe existir una óptima calidad ambiental interior. La monitorización de esta calidad ambiental, tradicionalmente, incluye el estudio de la humedad y la temperatura de los espacios interiores ya que es bien conocido que sus valores elevados y fluctuaciones rápidas pueden alterar los materiales constitutivos de las obras de arte. Sin embargo, hay muchos otros parámetros que se deben estudiar para tener una visión completa de los riesgos potenciales relacionados con ambientes patrimoniales. En este trabajo, planteamos la importancia de una monitorización integral sistemática de la calidad ambiental de un bien patrimonial q…
The conformational properties of dehydrobutyrine and dehydrovaline: theoretical and solid-state conformational studies
2010
Dehydrobutyrine is the most naturally occurring dehydroamino acid. It is also the simplest dehydroamino acid having the geometrical isomers E/Z. To investigate its conformational properties, a theoretical analysis was performed on N‐acetyl‐α,β‐dehydrobutyrine N′‐methylamides, Ac‐(E)‐ΔAbu‐NHMe and Ac‐(Z)‐ΔAbu‐NHMe, as well as the dehydrovaline derivative Ac‐ΔVal‐NHMe. The ϕ, ψ potential energy surfaces and the localised conformers were calculated at the B3LYP/6‐311 + + G(d,p) level of theory both in vacuo and with inclusion of the solvent (chloroform, water) effect (SCRF method). The X‐ray crystal structures of Ac‐(Z)‐ΔAbu‐NHMe and Ac‐ΔVal‐NHMe were determined at 85 and 100 K, respectively. …
