Periferia senza marginalità. La rigenerazione territoriale come strategia e strumento per il Friuli-Venezia Giulia
No full textIn anni recenti, le periferie territoriali hanno catalizzato l’attenzione della ricerca urbanistica sia nel contesto italiano che europeo, dando esito a numerose interpretazioni: le ‘aree interne’ della SNAI, le ‘inner peripheries’ di ESPON, l’Italia di Mezzo, etc.
Il territorio della regione Friuli Venezia Giulia, mosaico complesso di contesti e sistemi insediativi, rientra puntualmente in molte di queste “mappe della marginalità”, seppur sempre in modo parziale e discontinuo. Territorio non esente da criticità e fragilità diffuse (cfr. la parte 2 del presente contributo) il Friuli Venezia Giulia rientra però, insieme al Trentino Alto Adige e alla Liguria, nei territori italiani con il più elevato indice di qualità della vita su base EU (ESPON QoL Report, 2020). Questa apparente dicotomia suggerisce che si può essere “periferia” senza marginalità, ovvero che la condizione di perifericità rispetto ai sistemi urbano-metropolitani dominanti non è di per sé limitante, ma anzi, possa potenzialmente essere vantaggiosa in termini di una accresciuta resilienza socioeconomica e ambientale a fronte dei grandi cambiamenti in atto.
In questo quadro si inserisce una visione alternativa del Friuli Venezia Giulia, come “ecoregione” nel contesto alpino-padano (Fabbro, 2021) e in relazione ai vicini territori europei, in grado di integrare la molteplicità di situazioni esistenti con una rinnovata abitabilità alla scala territoriale. Attraverso le ricerche condotte, gli autori avanzano la tesi che per attuare questa visione sia necessario sviluppare un approccio di “rigenerazione territoriale”, che esuli dalla tradizionale dimensione urbana e locale propria della rigenerazione urbana, ma capace di trattare e manipolare la natura sistemica e strutturale del territorio, nelle sue componenti infrastrutturali, artificiali (urbanizzazione, energia, uso agricolo dei suoli) e naturali (ecosistemi fluviali, forestali, costieri). Nella ricerca qui presentata essenziale risulta essere il supporto tecnico e scientifico della “Comunità di lavoro per la Rigenerazione territoriale” che, promossa dalla sezione Friuli Venezia Giulia dell’Istituto Nazionale di Urbanistica, riunisce attori del territorio quali Amministrazioni pubbliche, Enti e Associazioni
Resilience, Performance and Strategies in Firms’ Reactions to the Direct and Indirect Effects of a Natural Disaster
No full textThis work investigates the impacts of the 2012 Emilia-Romagna earthquake and looks at the capacity of the regional economic system to adapt to the shock generated by the seismic event. We contribute to the literature by distinguishing two different effects: direct (i.e. damages to production factors of the focal firm) and indirect effects (e.g. disruptions that affected industrial and business partners). The original dataset used and the chronological sequence of the information allow us to provide insightful evidence. The analysis of the two related effects generated by the same shock provides insights on the overall capacity of a regional system to adapt. Namely, the indirect damages appear as relevant as the direct damages, especially when looking at indicators of firm performance. In addition, indirect impacts are also relevant in shaping firm strategies and thus firm resilience

Myurellopsis Fedosov & Malcolm & Terryn & Gorson & Modica & Holford & Puillandre 2019, new genus
No full textGenus Myurellopsis new genus (Fig. 7 G–I) Type species: Terebra undulata Gray, 1834. Zoobank registration: urn:lsid:zoobank.org:act: EC3F14B2-3595- 482B-9890-399BA78A7631 Definition: Includes all species included in the clade E5B of Modica etal. (2019) and those that show a combination of conchological, anatomical and distribution characteristics closely comparable with Myurellopsis undulata or any genetically proven member of the genus. Diagnosis: Diagnostic nucleotide combinations in Table 10. Shell: Small to medium-sized (< 50 mm), pinkish or orange, often with white subsutural band. Protoconch multispiral. Sculpture of strong, rounded, slightly undulating ribs, polished in appearance. Row of punctations with groove partially cutting ribs forming subsutural band. Interstices between ribs deep, narrow, bearing regular striae, often darkly coloured. Adapical parts of ribs forming one row of rounded nodules, separated from their lower portions by shallow depression or partial groove. Siphonal canal moderately long, tapering, with weakly developed fasciole. Anatomy: Two distinct states—either all typical foregut structures present, or all lacking; in latter case, accessory proboscis structure present. Distribution: Throughout Indo-Pacific; intertidal to upper bathyal depths (to 358 m), typically shallow. Remarks: Species in Myurellopsis n. gen. appear conchologically closest to Myurella species, but can be differentiated by the sharper, more elevated ribs, often with nodes on the subsutural band or top of the whorls. Etymology: The name refers to the close resemblance between its members and species in the genus Myurella. Gender feminine.

The relaxed Dirichlet energy of manifold constrained mappings
No full textThe Dirichlet energy of Sobolev mappings between Riemannian manifolds is studied.
After giving an explicit formula of the polyconvex extension of the energy for currents
between manifolds, we prove a strong density result. As a consequence, we give an explicit
formula for the relaxed energy. The fractional space of traces of W ^(1,2)-mappings is also treated
The Black Hole of Transport Logistics Efficiency: A Multi-Method Study on Yard Management
No full textABSTRACT
Yard management is crucial for warehouse efficiency, as
it accelerates and aligns incoming and outgoing material
flows at these sites. This is especially relevant in modern
logistics and supply chain management because recent
market trends demand increasing product assortments,
which must be produced, processed, and delivered in
ever shorter times. While efficiency improvements
within warehouses have received considerable interest
in operations management research, prior studies have
generally failed to establish how to design and evaluate
processes at warehouse sites. Research on decision
prioritisation regarding critical sub-processes in yard
management could offer interesting new insights,
helping to increase overall warehouse efficiency
through the prioritisation of critical optimisation
sub-processes. Accordingly, this paper examines
the prioritisation and evaluation of critical yard sub-
processes for efficient yard management at warehouse
sites. A multi-method research approach is applied,
combining analytic hierarchy process (AHP) interviews
with a detailed literature review and quantitative
empirical data analysis to allow for triangulation of the
results to develop theoretical contributions and practical
implications. Five critical yard sub-processes are
identified and prioritised: management of the shunting
system, registration at the gateway, allocation of trucks
to gates/parking spaces, removal of a transport unit
from the gate, and exit control
A MgB2 superferric racetrack magnet
No full textA magnesium diboride, cryogen-free, H-dipole magnet with cold iron yoke was constructed and tested. The racetrack coil, 48 cm long, was wound with 350 m of nickel-clad, copper-MgB2 tape. The iron yoke forms a 2.6 cm gap. The magnet was connected to a cryocooler and tested at different temperatures ranging between 8.5 and 24 K. The maximum current, 263 A, was reached, without training, at 8.5 K. The corresponding field in the gap was 2.35 T
Use of stable isotopes to investigate dispersal of waste from fish farm as a function of hydrodynamics.
No full textStable isotopes were used to examine differential effects of fish farm waste on the water column and sediments. To achieve this objective, we chose 3 marine fish farms located along the coast of Sicily (Mediterranean Sea) as point-source disturbances, and a control area. The hypothesis that carbon and nitrogen isotope composition of particulate (POM) and sedimentary (SOM) organic matter varied with increasing distance (from cages to 1000 m) was tested at 3 levels of hydrodynamics: low (mean velocity of current [MVC] ∼12 cm s -1), intermediate (MVC ∼22 cm s-1), and high (MVC ∼40 cm s-1). Different isotopic signals from allochthonous (fish waste) over natural (phytoplankton, terrigenous, and sand microflora) inputs allowed identification of the 'spatial effect regime' of fish farming. The increasing water current velocities seem to proportionally enlarge the relative area of influence of the cages, particularly on sediments. At low hydrodynamics, an increasing contribution of terrigenous signals was inferred: POM and SOM showing a depleted gradient of C (ranging from -22.0 to -24.0‰) and N (from 5.0 to 2.0‰). At an intermediate hydrodynamic level, C and N showed a slight increase in waste contribution, particularly in POM (δ15N from 2.6 to ∼4.0‰). At high hydrodynamics, an enriching isotopic gradient (δ15NPOM-SOM from 1.8 to 4.6‰) suggested a notable contribution of fish waste. Accordingly, the dispersal of waste from the cages seemed to be related to movements at the bottom of the water column, confirming the recently identified role played by resuspension movements
