"liberare i segni di Roma". Archeologia e centro storico ne l caso di Brescia (1893-1941)
No full text«Liberare i segni di Roma». Archaeology and historic centre, the example of Brescia (1823-1941) The author reconstructs the formation of the urban archaeological site of the city of Brescia (the most homogeneous and important in North of Italy) and tries to explain the reasons for the partial failure of that ambitious program. Since the early years of 19th century to the first half of 20th century, some ambitious programs were partially carried out in this area. Some reconstruction works were proposed – which required substantial economic and technical resources - with the purpose of enhancing the last fragments of those celebrated ancient buildings. The story starts in the early years of the nineteenth century with the excavations and the following partial reconstruction of the Tempio Capitolino, and ends in the 1950s with a town-planning scheme (1957) which, with regard to the historic city centre, inspired by the original proposal, developed between the two world wars (in particular, on the occasion of celebrations for the Augustus Bimillenary, 1936-37). It unveiled (not without some related demolition of several houses) an archeological area that was even larger than the universally condemned urban demolition of the Piazza Vittoria area, by Marcello Piacentini (1932)

SIDEWALK DETECTION AND PAVEMENT CHARACTERISATION IN HISTORIC URBAN ENVIRONMENTS FROM POINT CLOUDS: PRELIMINARY RESULTS
No full textThe definition of physical accessibility in urban environments is a topic of recognized importance by policy makers and by international organizations. A first step to address the accessibility topic is the definition and characterisation of urban elements, like sidewalks, roads, and ramps. Sidewalk inventory plays a crucial role in this phase. In literature there are several ways to extract sidewalks from a point cloud, but they are all tailored on modern and standardized situations. For example the presence of a curb is assumed as the normality and the roads are supposed to have the same width along the path. When dealing with an Urban Heritage, some difficulties arise. In fact, in an historic urban environment ground irregularities should be taken in consideration: the paving is composed by different materials, curbs are not always present, and a Z difference between road and sidewalks is not so sure. In such cases existing methodologies cannot be applied. This paper present a method to semantically segment a point cloud, labelling sidewalks and roads. Sidewalks are also characterized by detecting their pavings. The method is tested on an Urban Heritage: the Unesco site of Sabbioneta, in northern Italy. The results are promising, sidewalks are detected with a precision of 80%, main errors are in corner areas. Paving characterisation is based on thresholds derived from some samples, and the method shows an high precision (more than 90%) in all the pavings considered
The stress impact on glutamate transmission: a key to mood and anxiety disorders
No full textDysfunction of the glutamate system is increasingly considered a core feature of neuropsychiatric disorders, including mood and anxiety disorders. Neuroimaging studies have shown consistent volumetric changes in brain areas where glutamate neurons predominate. In parallel, preclinical studies with rodent stress/depression models found dendritic remodeling/reduction of synapses in the same areas, suggesting these changes are major factors in psychopathology. Additional studies have shown that antidepressants may partly reverse maladaptive changes in synapses/circuitry of rodent models. Destabilization of glutamate release/transmission in cortical/limbic areas, in turn induced by stress and glucocorticoids, seems to be crucial for these structural/functional changes [1].
We have previously shown that acute stress induces rapid enhancement of depolarization-evoked glutamate release/transmission in prefrontal and frontal cortex (PFC/FC), by increasing corticosterone levels and stimulation of synaptic glucocorticoid/mineralocorticoid receptors (GR/MR). In addition, we have shown that chronic antidepressants are able to prevent the enhancement of glutamate release induced by acute stressors [2]. We have now evidence that acute stress rapidly enhances glutamate vesicles mobilization and increases the readily releasable pool size, through activation of synaptic GR/MR-mediated non-genomic mechanisms. In vitro application of corticosterone to purified PFC/FC synaptosomes mimics vesicles mobilization, but does not enhance depolarization-dependent glutamate release and transmission. Our results suggest that rapid (non-genomic) synaptic action of corticosterone on the RRP size is necessary, but not sufficient, to increase glutamate release/transmission in PFC/FC. Enhancement of glutamate release/transmission likely needs the activation of delayed, possibly genomic, mechanisms. These studies may help defining new targets for pharmacological treatments of mood and anxiety disorders
ACCESSIBLE PATH FINDING FOR HISTORIC URBAN ENVIRONMENTS: FEATURE EXTRACTION AND VECTORIZATION FROM POINT CLOUDS
No full textSidewalk inventory is a topic whose importance is increasing together with the widespread use of smart city management. In order to manage the city properly and to make informed decisions, it is necessary to know the real conditions of the city. Furthermore, when planning and calculating cultural routes within the city, these routes must take into account the specific needs of all users. Therefore, it is important to know the conditions of the city's sidewalk network and also their physical and geometrical characteristics. Typically, sidewalk network are generated basing on existing cartographic data, and sidewalk attributes are gathered through crowdsourcing. In this paper, the sidewalk network of an historic city was produced starting from point cloud data. The point cloud was semantically segmented in "roads"and "sidewalks", and then the cluster of points of sidewalks surfaces were used to compute sidewalk attributes and to generate a vector layer composed of nodes and edges. The vector layer was then used to compute accessible paths between Points of Interest, using QGIS. The tests made on a real case study, the historic city and UNESCO site of Sabbioneta (Italy), shows a vectorization accuracy of 98.7%. In future, the vector layers and the computed paths could be used to generate maps for city planners, and to develop web or mobile phones routing apps
