Towards a Definition of Landscape Resilience: The Proactive Role of Communities in Reinforcing the Intrinsic Resilience of Landscapes
No full textThe resilience approach seems to be related to the understanding of the concept of strong sustainability (Neumayer, 2003; Voghera & Giudice, 2019), which requires flexibility, integration, and empowerment. Resilience can be a useful lens to interpret the transformative action of territory and landscape, seeking a balance through projects still linked to the landscape in a generic way. A balance that must be multiple, dynamic (Butler et al., 2019; Loupa Ramos et al., 2016) and co-evolutionary (Davoudi, 2012), capable of maintaining the robustness and identity (Aimar, 2019), function and structure of the system (Walker et al., 2004) in adapting to continuous transformations (Adger et al., 2005; Folke, 2016). In this sense, several research topics are emerging, firstly that of landscape resilience. This is a borderline, polysemic concept, whose debate is still opened in the literature, where resilience at the urban scale is discussed through an ecological and landscape approach to urban and territorial design (Meerow et al., 2015). Currently, the landscape approach does not seem to be the right key to build resilience, as the landscape plan is an ineffective tool at the local project scale. Rather, the focus should be on territorial governance and the involvement of social actors. Indeed, there is a belief that landscape can be a lever to engage and empower communities, with place-related and people-centred approaches (ICCROM, 2015). Their contribution would be relevant to increase the inherent resilience of a system (Brunetta et al., 2019), through active conservation (Winter et al., 2018) of cultural and landscape heritage

Tirana: la nuova vita della Piramide di Hoxha
No full textSe guardiamo oggi alla città, ci si trova davanti alla realtà di una capitale fatta di 111 anni, caratterizzata da una commistione di epoche e linguaggi (ottomano, italiano, realista-socialista e, negli ultimi anni, contemporaneo), accostati in una dimensione urbana contenuta, di circa 1.100 kmq e 900.000 abitanti, ancora organizzata prevalentemente attorno al centro storico con piazza Scanderbeg e alle direttrici viarie verso le città di Kavaja, Dibra e Durazzo. Tra frammenti di quartieri di origine ottomana e opere moderniste sopravvissute alla corsa verso il contemporaneo di una nazione in continua tensione tra sviluppo economico e salvaguardia della memoria, a definire le assialità della metropoli è ancora oggi il suo boulevard monumentale “Martiri della Nazione” (Bulevardi Dëshmorët e Kombit). Lungo 1.060 m, collega in direzione nord-sud la centrale piazza Scanderbeg fino all’ex Casa del Fascio, oggi sede dell’Università Politecnica. [...

Cátedra de Química Aplicada; Argentina.Nowadays, biocatalytic stereoselective reduction of prochiral ketones is one of the
most important methodologies in organic synthesis for the preparation of chiral
alcohols. These enantiomerically pure alcohols are very important because they
are key precursors in the obtaining of pharmaceutical compounds. Recently, a
screening on fifty six strains of bacteria and fungi was made for our team toidentify
microorganisms capable of performing the stereoselective reduction of
acetophenone (AP) to 1-phenylethanol (1-PE). From this study a strain of
Geotrichum spp.has been isolated and characterized, and this yeast has presented
anexcellent conversion (>99%) and stereoselectivity (>99.9 e.e.%) in the
preparation of (R)-1-PE from AP.Fil: Decarlini, M. F. Universidad Católica de Córdoba. Facultad de Ciencias Químicas; Argentina.Fil: Vázquez, A. M. Universidad Católica de Córdoba.

One Phase vs Two-Phase Modelling of Infiltration Processes
No full textBecause of global warming, the frequency and harmfulness of climate
extrememeteorological events have increased and are expected to increase. Events such as droughts, heatwaves, storms, floodings strongly impact the functioning of critical infrastructure, as well as the stability and degradation of man-made earthworks and natural slopes. The shallower portions of natural soils and earthworks are thus exposed to increasingly severe dry and hot seasons and to intense rainfalls, which affect the depth of the water table and the hydraulic circulation, triggering material degradation and instabilities. Robust modelling of the soil-atmosphere interaction, correctly accounting for unsaturated flow and boundary conditions, is a requirement of modern geotechnical engineering. The assumptions made when modelling infiltration, in terms of infiltration rate, pore and air pressure distribution and evolution, have in fact a relevant impact on model predictions. As a fraction of the pore space of unsaturated soils is occupied by the gas phase, composed of water vapour and dry air, a complete model of infiltration requires accounting for the inflow of the liquid phase and the outflow of the gas phase. Contrarily, infiltration is very often modelled accounting only for the inflow of liquid water. This work explores the consequences and limitations of such simplification by comparing the predictions obtained by adopting both a two-phase and a one-phase model for
the simulation of the infiltration processes
An assessment of the NTC18 stratigraphic seismic amplification factors
No full textThe present study aims at an evaluation of the simplified procedure for the prediction of stratigraphic amplification of the seismic action in the new Italian building code (NTC18). For this purpose, a stochastic database of ground response analyses has been implemented, by performing equivalent linear analyses on a collection of one-dimensional ground models. The models are representative of different subsoil conditions of engineering interest. The reference seismic input consists of collections of acceleration time histories, which are compatible with the seismological features of a number of sites with different seismic hazard. The results have been interpreted computing synthetic amplification parameters, allowing for the evaluation of the reliability of the subsoil classification system. The study also assesses the effect of some specific features, such as stiffness inversions or soil type. The results show that code prescriptions provide a reasonable estimate of seismic amplification. However, the large variability indicates that the simplified approach should be used with caution, especially for critical facilities
Study and results of an onboard brake monitoring system for freight wagons
No full textThis paper presents the background study, the development and the tests of a monitoring system for intermodal freight wagon. The prototype of the on-board unit, developed by the research group of Railway Engineering of Politecnico di Torino, was installed and tested on an intermodal freight wagon owned by the company Ambrogio Trasporti S.p.a. as part of the project ITS Cluster Italy 2020. Significant advances have been made in the field of freight train monitoring. In recent years, many companies have presented specific devices with the aim of monitoring the operating conditions of goods wagons. The developed prototype was tested on real track. The main vehicle parameters monitored during the tests were the temperature of brake blocks, the operating pressures of the brake system, and the vehicle accelerations. The measurements allowed the team to verify the effectiveness and reliability of the monitoring system in harsh conditions. The significant amount of measured data were then used to validate a first energetic model useful for subsequently developing monitoring and diagnostic algorithms
Towards reconstructing rural landscapes: A case study of Italian Mongardino
No full textThis paper intends to propose an integrated methodology for reconstructing the rural landscape of Mongardino, a municipality in the cross-border area of the UNESCO Buffer Zone of the ‘Vineyard Landscape of Piedmont: Langhe-Roero and Monferrato’. A multi-source approach was established to detect land use changes that occurred in its dynamic agricultural mosaic from the 17th century to date and intuiting future land-use variations. Qualitative comparisons have combined literature, historical maps from archives, repeated photo- and postcard-based research, statistical dataset interpretations and WebGIS surveys. This research has delineated the significance of historical studies to detect and interpret current matrices of change and build an enhanced comprehension of the evolutionary trajectories of a wine-growing landscape over time. Findings reveal that changes do not follow administrative boundaries but rather linear, non-linear, external and internal dynamics that are local and context-dependent. On the one hand, no asymmetries or prevailing trends have been found between the areas encompassed or not in the UNESCO Buffer Zone. On the other hand, land-use and historical permanencies are detected as indicators of integrity and qualifying landscape elements upon which to build rural strategies and policies for local-based landscape planning and management

The Fifth Landscape: Art in the Contemporary Landscape
No full textAt the Shaping the City conference organised by the European Cultural Center at the 2018 Venice Biennale, the concept of the Fifth Landscape (or Landscape 5.0) was exhibited for the first time. Thanks to creativity, the goal is to experiment with spaces for the sake of social and cultural imagination, in which it is no longer just a question of architecture but of dreams and social imagination. “Ideal” spaces are related to their impact on the architecture, art and human hopes. In the Fifth Landscape, the contemporary prefers the moment of the artistic gesture that will be remembered but that is not relived in everyday life. Temporary installations in urban centers and open spaces become an occasion for new uses of the different environments, such as living them in a completely new way with novel prospects for the future. If the First Landscape is the managed forest, then the Second is the cultivated field. The Third is the abandonment of places at the hands of man, according to Gilles Clément, and the Fourth is where art is used to counter urban degradation and solitude. The Fifth Landscape is generated by temporary works that, catalysing territorial force, stimulate people to live in the environment in a new way, making it dreamlike. The strong emotional impact on the collective memory transmits, in addition to the true meaning of the work, a sense of uniqueness of the moment that one is experiencing. New visions of landscapes are provided to the community, in which art, architecture, design and nature are confronted using environmental sustainability and the landscape itself as themes. What influences will cultural dematerialisation have on the landscape? How will the sense of beauty in the future society be transmitted and realised? If it is, through which artistic and ephemeral gestures will it appear? Helped by virtuous and suggestive artworks among which Vesuvius by Diego Repetto, Illusion by Alberto Timossi and ARTgo by Diego Repetto, we try to answer the proposed questions, thus understanding more about the potential future perception of the landscape in a continuous search for beauty
