    Abstract. Advanced 3D technology, in line with the directives of the European Commission's Reflective 7 - Horizon 2020 project, allows to represent in an organized and accurate way (geometrically and chromatically speaking) any type of artefact belonging to the Cultural Heritage. This article will deal with the specific case-study of the research carried out in the archaeological site of the Roman fluvial port of Aquileia, in collaboration with the University of Trieste. Thirtysix MA Architecture students attending the experimental course in "Technologies for the conservation and enhancement of architectural heritage" were involved. The Advanced 3D model of the fluvial port was conveniently divided into 15 sectors, in order to allow the assignment of each sector to a different group of students. The students, using the tools provided by the proprietary EasyCUBE PRO software, were able to create a digital database with an accurate 3D representation of all types of degradation affecting the archaeological structures existing in situ. Starting from the digital database, the students created a report containing the surfaces, volumes, count of the specific elements and all the other textual and graphical data related to the degradation processes. The collected data allowed to produce a metric estimate of the restoration intervention and to realize visual simulations of the post-intervention result. This experience gave the chance to evaluate the advantages of creating a digital database of 3D representations of the various forms of degradation, also in terms of possible future developments.</p

    THE REAL IN THE VIRTUAL. THE 3D MODEL IN THE CULTURAL HERITAGE SECTOR: THE TIP OF THE ICEBERG

    The twenty-year and interdisciplinary research activity carried out by Virtualgeo has focused on the development of new methods and tools for 3D modeling that go beyond the simple digital-virtual reconstruction of solid modelling, in order to realize three-dimensional informative and photogrammetric representations that faithfully reproduce reality. These so called Advanced 3D models are the basis for carrying out metrological investigations to support the design and the BIM database population. In particular, in this paper we will deal with the segmentation tool, which allows the classification of the photogrammetric 3D model (material, degradation and chronological features). In detail, we will illustrate the collaboration experience between Virtualgeo and the University of Trieste, course in Technologies for the conservation and enhancement of architectural heritage of the Master's Degree in Architecture. The experience focused on the study of the archaeological site of the Roman river port of Aquileia, which Advanced 3D model was supplied by Virtualgeo. Firstly, the work focused on the informative contents necessary for the subsequent elaborations (different types of materials, alteration/degradation forms), starting from the use of coded lexicons (UNI 11182/2006). Subsequently, the quantitative data were associated to each category of homogeneous elements, obtainable from the segmentation (“mapping”) of the 3D model. This experience gave the chance to test the EasyCUBE PRO software: it was gradually adapted to the specific needs emerged both during the analysis of the site and the definition of conservation interventions, so as the outputs that can be generated after the elaboration of the Advanced 3D model

    Randomized trial on the effects of a combined physical/cognitive training in aged MCI subjects: the Train the Brain study

    Age-related cognitive impairment and dementia are an increasing societal burden. Epidemiological studies indicate that lifestyle factors, e.g. physical, cognitive and social activities, correlate with reduced dementia risk; moreover, positive effects on cognition of physical/cognitive training have been found in cognitively unimpaired elders. Less is known about effectiveness and action mechanisms of physical/cognitive training in elders already suffering from Mild Cognitive Impairment (MCI), a population at high risk for dementia. We assessed in 113 MCI subjects aged 65-89 years, the efficacy of combined physical-cognitive training on cognitive decline, Gray Matter (GM) volume loss and Cerebral Blood Flow (CBF) in hippocampus and parahippocampal areas, and on brain-blood-oxygenation-level-dependent (BOLD) activity elicited by a cognitive task, measured by ADAS-Cog scale, Magnetic Resonance Imaging (MRI), Arterial Spin Labeling (ASL) and fMRI, respectively, before and after 7 months of training vs. usual life. Cognitive status significantly decreased in MCI-no training and significantly increased in MCI-training subjects; training increased parahippocampal CBF, but no effect on GM volume loss was evident; BOLD activity increase, indicative of neural efficiency decline, was found only in MCI-no training subjects. These results show that a non pharmacological, multicomponent intervention improves cognitive status and indicators of brain health in MCI subjects

    This paper aims to reconsider the manuscript by Jacopo Valvasone (1499-1570), formerly owned by the Earl of Leicester (now British Library, Additional MS 49369), which Theodor Mommsen borrowed and inspected in 1876, just before the publication of the second part of CIL V. In the letter that he wrote to thank the Vicar and Librarian of Halkham Hall, Mommsen declared that Valvasone joined \u201cthe the long list of forgers\u201d. The analysis of forgeries in Valvasone\u2019s manuscript could show whether Mommsen was right in his opinion
