This paper presents a study carried out in the Italian region of Umbria, after the 2016 Central Italy earthquake. The aim is to address the problem of the conservation and protection of architectural heritage in Italy. The application of retrofitting strategies, while improving the seismic performance of historic—and frequently listed by conservation bodies—buildings, will not significantly alter their appearance, will be reversible, and fall within the principle of minimum intervention (minimal (least) intervention (or conservative repair)). These issues were evaluated in the paper by considering the different points of view of structural engineers and conservators. Heavy structural-oriented interventions as well as the underestimation of the importance of the structural safety for masonry monuments has produced, in the past, irreversible damage to important buildings and monuments, and loss of architectural heritage in Italy. The requirement of structural safety, especially for monuments located in seismic-prone areas, is compared with the need for conservation. The Italian building guidelines for interventions of cultural heritage are also discussed, highlighting some limitations and important advancements.

Central Italy Earthquake

We present here the first application of the fast reacting framework for 3D simulations of seismic wave propagation generated by earthquakes in the Italian region with magnitude Mw 5. The driven motivation is to offer a visualization of the natural phenomenon to the general public but also to provide preliminary modeling to expert and civil protection operators. We report here a description of this framework during the emergency of 24 August 2016 Mw 6.0 central Italy Earthquake, a discussion on the accuracy of the simulation for this seismic event and a preliminary critical analysis of the visualization structure and of the reaction of the public.

Comparison Of The Results

AbstractThe paper presents the comparison of the results obtained on a masonry building by nonlinear static analysis using different software operating in the field of continuum and discrete-macroelement modeling. The structure is inspired by an actual building, the "P. Capuzi" school in Visso (Macerata, Italy), seriously damaged following the seismic events that affected Central Italy from August 2016 to January 2017. The activity described is part of a wider research program carried out by various units involved in the ReLUIS 2017/2108—Masonry Structures project and having as its object the analysis of benchmark structures for the evaluation of the reliability of software packages. The comparison of analysis was carried out in relation to: global parameters (concerning the dynamic properties, capacity curves and, equivalent bilinear curves), synthetic parameters of structural safety (such as, for example, the maximum acceleration compatible with the life safety limit state) and the response in terms of simulated damage. The results allow for some insights on the use of continuum and discrete-macroelement modeling, with respect to the dispersion of the results and on the potential repercussions in the professional field. This response was also analyzed considering different approaches for the application of loads.

In his excellent study of medieval Italian society, Hyde makes a thought-provoking comparison of ‘the Italians of the age of Dante’ with the humanists of a later generation. The former he sees as distinguished by ‘a sense of continuity with the past and with other parts of the Catholic world’ from the humanists who ‘concentrated on what was close at hand, digging deep rather than spreading wide, so that their world revolved around central Italy.’ It is not my intention here to dispute this assertion, but to use it to stimulate reflection on the nature of Italian self-awareness in the early renaissance period, in the light of a further contrast between Hyde’s two ages which he does not himself emphasise.

Definition Of

The use of renewable energies as alternative to fossil fuels has value from different points of view and has effects at environmental, social and economic level. These aspects are often connected to each other and together define the overall sustainability of bioenergy. At European level, the Directive 2009/28/EC gives the basic criteria for the estimation of sustainability of biofuels and indicates a minimum threshold of 35% of greenhouse gas saving for a biofuel in order to be considered sustainable. The Directive gives the possibility to identify standard regional values for the cultivation steps that could be utilized for the certification. This paper aims to give a contribution to the definition of these values considering the RED methodology applied to the sunflower cropped in central Italy which is characterized by a hilly landscape and not-irrigated crops. To determine input and output of sunflower cultivation in the central Italy, the results of PROBIO project, carried out by the Authors, were used. The sustainability of biodiesel produced from sunflower grown in central Italy is variable and depends on the nitrogen input and seasonal climatic conditions that affect the yields. The greenhouse gases savings of the Italian chain is 40% in average, greater than the required 35% and would be possible to assign this value as standard to the biofuel chain <em>biodiesel from sunflower cultivated in central Italy</em>. Using an averaged regional standard value guards against the possibility of considering unsustainable harvesting in unfavourable years and seeing it overestimated in the favourable ones.

Points Of View

Within the past few years a series of papers emanating from this laboratory has dealt with the respiration of normal subjects and psychotic patients from psychological and physiological points of view. Linking up the chain of these investigations, we have tried in this study to get some information about the respiratory type and the ventilation in different groups of mental patients, especially of schizophrenics.
