Viene sottolineata in particolare la rapida crescita qualitativa e quantitativa delle produzioni metallurgiche fin dalle fasi di formazione urbana databili alla prima età del ferro
Earthquake Response of Cold-Formed Steel-Based Building Systems: An Overview of the Current State of the Art
No full textBuilding systems fabricated with cold-formed steel (CFS) profiles and members made of wood, gypsum, or other materials allow solving a range of issues arising in common constructional elements thanks to their advantages, such as lightness, strength, durability, physical stability, sustainability, and cost-effectiveness. As a result of this inherent competitiveness of CFS based buildings, their use has been gradually increasing in recent years both in the field of structural systems as non-structural architectural components and, above all, in the area of earthquake resistant buildings, where lightness play a key role. After a general introduction, the paper gives an overview of the current codification and ongoing research on CFS non-structural architectural and structural systems. Finally, the main conclusions are summarised, and possible future developments are outline

Falsolikanella campanensis (Azéma and Jaffrezo, 1972) Granier, 1987 revisited on type material, evidence of polyphysacean nature (green algae)
No full textThe genus Falsolikanella, introduced by Granier (1987), was based on the basal Cretaceous species Likanella campanensis Azéma and Jaffrezo (1972) and assigned to the tribe Diploporeae (Pia, 1920) emend. Güvenc, 1979 within the green alga order Dasycladales. Later, other species were assigned to Falsolikanella. Sections of the type specimens of Likanella campanensis are reviewed. They show that in this species, the arrangement of the laterals is not metaspondyl, but typical of the genus Actinoporella (Gümbel in Alth, 1882) emend Conrad, Praturlon, and Radoičić, 1974, with coronae arising from a single primary lateral. Therefore, the species is assigned to the genus Actinoporella within the tribe Acetabularieae Decaisne, 1842, family Polyphysaceae Kützing, 1843, and the generic attribution of other species previously assigned to Falsolikanella is discussed.

Review Pages: The Times They Are a-Changin' 1 (2019)
No full textStarting from the relationship between urban planning and mobility management, TeMA has gradually expanded the view of the covered topics, always remaining in the groove of rigorous scientific in-depth analysis. During the last two years a particular attention has been paid on the Smart Cities theme and on the different meanings that come with it. The last section of the journal is formed by the Review Pages. They have different aims: to inform on the problems, trends and evolutionary processes; to investigate on the paths by highlighting the advanced relationships among apparently distant disciplinary fields; to explore the interaction’s areas, experiences and potential applications; to underline interactions, disciplinary developments but also, if present, defeats and setbacks. Inside the journal the Review Pages have the task of stimulating as much as possible the circulation of ideas and the discovery of new points of view. For this reason the section is founded on a series of basic’s references, required for the identification of new and more advanced interactions. These references are the research, the planning acts, the actions and the applications, analysed and investigated both for their ability to give a systematic response to questions concerning the urban and territorial planning, and for their attention to aspects such as the environmental sustainability and the innovation in the practices. For this purpose the Review Pages are formed by five sections (Web Resources; Books; Laws; Urban Practices; News and Events), each of which examines a specific aspect of the broader information storage of interest for TeMA
Un pianeta solo. L’ecospiritualità: vettore di una società “cosmopolita”?
No full textLa ecospiritualità (Choné, 2017) potrebbe farsi vettore di una “svolta cosmopolita” (Beck, Magatti, Martinelli, 2005) , pur con tutte le contraddizioni e difficoltà del caso. L’entità della posta in palio – al limite la sopravvivenza stessa della biosfera – imporrebbe, almeno in linea di principio, di superare divisioni e conflitti in vista di un risultato comune dell’umanità, percepito come di importanza vitale (Beck, 2017). Gli scenari apocalittici prospettati dalle implicazioni del Climate Change parrebbero dunque, in modo solo apparentemente paradossale, rappresentare una risorsa simbolica e di senso per il dialogo interreligioso, spalancando imprevedibili opportunità di rinnovate logiche di cooperazione internazionale .
Obiettivo di questo paper è ragionare criticamente intorno a tali questioni, allo scopo di offrire un piccolo contributo alla spinosa quanto decisiva relazione tra fedi religiose e possibilità di sviluppo e cooperazione internazionale in un paesaggio mondiale di crescente globalizzazione
Hydrothermal system monitoring by continuous magnetotelluric time series: sensitivity analysis and data denoising
No full textThe MT method is a good candidate for characterizing the dynamics of geothermal or hydrothermal systems as it is suitable for deep exploration of the subsurface (from one hundred meters to hundreds of kilometers) in terms of electrical resistivity values, which are strongly sensitive to variations in underground fluid temperature and gas saturation. However, at present, the potential of the MT method for monitoring purposes has not been completely assessed as the only studies in this field focus on monitoring fluid injections in Enhanced Geothermal Systems. The present PhD thesis aims to provide a contribution in this research field by presenting the first attempt for studying the sensitivity of the MT response to natural geothermal (or hydrothermal) system variations. The sensitivity of the MT method has been studied by simulating spatial and temporal evolution of temperature and gas saturation distributions in a hydrothermal system and by calculating the MT response at different time steps through continuous MT measurements. In particular, two possible scenarios have been considered: the first related to an increase in the fluid flow rate from the system source, the second associated to an increase in the permeability of the rocks hosting the hydrothermal system. For each scenario, the sensitivity has been analyzed by evaluating the time interval needed to observe significant variations in the MT response. This study has been applied to the hydrothermal system of the Campi Flegrei volcanic district (southern Italy) and it has shown that the MT monitoring is much more sensitive to changes in rock permeability rather than in the fluid flow rate emitted by the source. In general, long time intervals not useful for volcano monitoring purposes are found if only changes in fluid flow rate are assumed to govern the hydrothermal system dynamics. Conversely, by increasing the permeability of the hosting rocks up to about one order of magnitude, significant resistivity variations are observed over a period ranging from one year and a half to three months. Such findings are promising and encourage the use of the continuous MT measurements in active volcano-hydrothermal areas.
Due to the high sensitivity of the MT data to presence of man-made noises that, if not properly detected, can lead to biased resistivity estimates, the present thesis focused also on the development of two non-standard denoising techniques for magnetotelluric data. Both the developed filters are based on the decomposition and analyses of the MT signal through the Discrete Wavelet Transform (DWT), whose use represents an innovative approach in MT processing. The DWT has been chosen considering the resolution that it provides in both time and frequency domains making it a powerful tool to deal with transient and non-stationary signals, as the man-made noise usually appears on the magnetotelluric recordings. The first proposed filter, called polarization filter, aims at detecting the presence of noise by analyzing the polarization of different portions of the electric components of the MT field and by removing those portions whose polarization is higher than a specific threshold. The second filter, called SOM filter, aims at discriminating noisy and clean impedance tensor estimates through a clustering performed with the Self-Organizing Map neural network. Both filters applied to synthetic and field MT data have proven effective in noise detection and in improving the quality of the impedance tensor estimates

Analyzing multiplex networks using factorial methods
No full textMultiplex networks arise when more than one source of relationships exists for a common set of nodes. Many approaches to deal with this kind of complex network data structure are reported in the literature. In this paper, we propose the use of factorial methods to visually explore the complex structure of multiplex networks. Specifically, the adjacency matrices derived from multiplex networks are analyzed using the DISTATIS technique, an extension of multidimensional scaling to three-way data. This technique allows the representation of the different types of relationships in both separate spaces for each layer and a compromise space. The analytical procedure is illustrated using a real world example and simulated data
Crowding and conformation interplay on human DNA G-quadruplex by ultraviolet resonant Raman scattering
No full textThe G-quadruplex-forming telomeric sequence (TTAGGG)4TT was investigated by polarized Ultraviolet Resonance Raman Scattering (UVRR) at 266 nm. The presence of 40% poly(ethylene glycol) and the so-called "self-crowding" condition were used to induce the hybrid-to-parallel topology transition. Analysis of frequency shifts with temperature showed the role of several functional groups in the topological transitions and provides structural dynamical information. Circular dichroism under similar conditions was used as a reference. UVRR shed light on the effect of intramolecular interactions and of local and environmental dynamics in promoting different G-quadruplex topologies, induced by solution conditions or by temperature changes. Overall, these findings showed the enormous potential of this spectroscopy for G-quadruplex conformational studies
