Improving the remote estimation of soil organic carbon in complex ecosystems with Sentinel-2 and GIS using Gaussian processes regression
2022
Abstract Background and aims The quantitative retrieval of soil organic carbon (SOC) storage, particularly for soils with a large potential for carbon sequestration, is of global interest due to its link with the carbon cycle and the mitigation of climate change. However, complex ecosystems with good soil qualities for SOC storage are poorly studied. Methods The interrelation between SOC and various vegetation remote sensing drivers is understood to demonstrate the link between the carbon stored in the vegetation layer and SOC of the top soil layers. Based on the mapping of SOC in two horizons (0–30 cm and 30–60 cm) we predict SOC with high accuracy in the complex and mountainous heterogene…
Georreferenciación GPS/INS de imágenes aéreas adquiridas con escáneres rotacionales: ejemplo práctico y resultados
2003
Con la reciente introducción en el mercado de escáneres aerotransportados, la utilización de sistemas integrados GPS/INS es fundamental y redunda en la adquisición de imágenes y en la generación de productos digitales muy competitivos, por ejemplo ortoimágenes. En este artículo se han expuesto las claves de la georreferenciación de imágenes lineales obtenidas con escáneres rotacionales y orientadas a partir de procedimientos mixtos. Los resultados conseguidos muestran que los nuevos sensores y las nuevas tecnologías aerotransportadas existentes son hoy en día operativas para fines cartográficos.
P-T path development derived from shearband boudin microstructure
2016
This work focuses on the development of a regional P-T-path from the Malpica-Lamego Ductile Shear Zone, NW Portugal, based on the microstructures of shearband boudins evolved during progressive simple shear. The combination of microstructural analysis, fluid inclusion studies, crystallographic pre- ffered orientation and fractal geometry analyses, allows to link several stages in the internal evolution of the boudin to regional P-T conditions. The boudinage process is initiated under differential stress after the original layer achieved sufficient viscosity contrast relative to the surrounding matrix. Two main transformations occur simultaneously: i) change in the external shape with contin…
Quantificação das estruturas de fluxo sin-magmáticas do Plutão de Vila Pouca de Aguiar: uma ferramenta para a quantificação estrutural e da qualidade…
2014
Mineral distribution pattern of Variscan post-tectonic granites from Vila Pouca de Aguiar Pluton (NE Portugal) were analyzed with methods partially based on fractal geometry and, with respect to rock inhomogeneity and anisotropy. The result of the analysis provides information about magmatic flux and mineral equilibrium processes in a crystallizing magma chamber. In addition, the used methods may also provide important information for the ornamental rock industry, because they allow fast and automatic evaluation of economic rock parameters.
Interpretative model of shearband boudins internal evolution in HT ductile shear zones
2012
The internal structure of a shearband boudin resulting from an original igneous, hydrothermal or metamorphic segregation tabular rigid body is a subject of scientific interest. It allows understanding the deformation mechanisms acting on homogeneous quartz aggregate activated during simple shear progressive deformation. This work is focused on the characterization of the internal evolution of shearband boudins, using microtextural analysis, fluid inclusions studies, fractal and OCP analysis. The proposed interpretative model shows the several structural stages that can be well established during the process of the internal evolution of shearband boudin.

Murature in terra cruda a Solunto (PA): problematiche conservative e indagini diagnostiche

Corporazioni, maestranze e mestieri d’arte a Palermo al tempo di Giacomo Amato (1643-1732)
2017
Ci si sofferma sull'attività poliedrica delle varie corporazioni e maestranze palermitane il cui operato, tra la seconda metà del XVII e i primi decenni del secolo successivo, è affiancato dall'estro creativo di Giacomo Amato e da altre emergenti personalità che incisero notevolmente nel rinnovamento artistico della città di Palermo.
