Soil forming factors

2007

The Russian geologist Vasily Dokuchaev (1846–1903), considered the father of soil science, was the first to identify and discuss, at the end of 19th century, what we know today as the “factors of soil formation”. He introduced the idea that soil is not something inert and stable, but it develops and evolves under the influence of climatic agents and vegetation that operate over time on a given geological substrate

Interface Detection Using a Quenched-Noise Version of the Edwards-Wilkinson Equation

2015

We report here a multipurpose dynamic-interface-based segmentation tool, suitable for segmenting planar, cylindrical, and spherical surfaces in 3D. The method is fast enough to be used conveniently even for large images. Its implementation is straightforward and can be easily realized in many environments. Its memory consumption is low, and the set of parameters is small and easy to understand. The method is based on the Edwards-Wilkinson equation, which is traditionally used to model the equilibrium fluctuations of a propagating interface under the influence of temporally and spatially varying noise. We report here an adaptation of this equation into multidimensional image segmentation, an…

Les discours de Libanios (discours 33-64) et la topographie d’Antioche

2012

The work is preparatory to elaborating a Libanius' lexicon attentive to the different nuances that seemingly common words can take on in a specific context such as that of his speech.

I.2 L’area Nord-Occidentale, in Carra et alii, Le aree funerarie fra isola e terraferma: esempi dalla Sicilia e dalla Sardegna, pp. 135-179

2015

Christian funerary evidence of Sicily and Sardinia are among the 3rd-4th century and 7th-8th. They were defined “useful fossils” to determine the incidence of the new religion in urban areas and the importance of the settlement spread over vast areas. The burial areas recognized in Sardinia are about one hundred; in Sicily they are more and more numerous; they are distributed along the route of the ancient roads and fall within the areas of competence of the diocese known by some letters of Pope Gregory the Great. They were divided into three categories: burial areas sub divo, rural and urban; burial underground areas, urban and rural; burial areas connected with a rural church or with a ma…
