Alberi sul tetto: uomini e donne in azione a NYC
2019
Il saggio riflette su alcune best pratics a NYC, relative all’implementazione di urban farms in aree dismesse o residuali. Il fenomeno viene letto: in termini storici, rispetto allo sviluppo complessivo della città, in termini politici, in termini civici e in chiave ecologica. Attraverso l’esplorazione delle dinamiche interne ai processi, è possibile apprezzare il valore, l’origine e l’efficacia della “partecipazione” e comprendere quale siano le interrelazioni tra le iniziative bottom-up e quelle istituzionali. Particolare attenzione viene rivolta al fenomeno delle Urban Rooftop Farms, gli orti sui tetti sorti su alcuni edifici (commerciali o ex produttivi) non più utilizzati; importanti n…
Una sostenibilidad social para la regeneración urbana de la ciudad inteligente
2013
Today the concept of “Smart City” is usual in the new urban and globalized vocabulary. Despite, the power of its modernity can conceal a insufficient reflection about the scope of its capacity to transform the urban and contemporary paradigm. This research offers a reflection regard what since the euro Mediterranean contest, the concept of “smart city”, can contribute to the international debate, and alerts about the importance to know the deliberation of the urban transformations through the history and also the contemporary age. Actualmente el concepto “Smart City” es habitual en el nuevo vocabulario urbano globalizado. Sin embargo, la potencia de su modernidad puede estar ocultando una r…
Palermo Open Frontier. Progettare l'interfaccia liquida porto-città
2019
Palermo Open frontier, ossia Palermo come "frontiera" aperta, indaga e propone una risposta progettuale alla problematica relazione di interfaccia tra la città di Palermo ed il suo porto. Il lavoro prende avvio dalla consapevolezza del controverso attuale legame tra la città di Palermo e l'acqua, nonché della complessità ed eterogeneità del tessuto urbano. L'area fulcro del progetto è l'interfaccia Molo Trapezoidale-Piazza Tredici Vittime, nodo fra il progetto di ampliamento del porto crocieristico/spugnoso e la città consolidata, ripensando lo spazio pubblico compreso fra la Cala ed il Castello a Mare, la via F. Crispi e la via Emerico Amari.
Properties of transmembrane helix TM1 of the DcuS sensor kinase of Escherichia coli, the stator for TM2 piston signaling
2021
Abstract The sensor kinase DcuS of Escherichia coli perceives extracellular fumarate by a periplasmic PASP sensor domain. Transmembrane (TM) helix TM2, present as TM2-TM2′ homo-dimer, transmits fumarate activation in a piston-slide across the membrane. The second TM helix of DcuS, TM1, is known to lack piston movement. Structural and functional properties of TM1 were analyzed. Oxidative Cys-crosslinking (CL) revealed homo-dimerization of TM1 over the complete membrane, but only the central part showed α-helical +3/+4 spacing of the CL maxima. The GALLEX bacterial two-hybrid system indicates TM1/TM1′ interaction, and the presence of a TM1-TM1′ homo-dimer is suggested. The peripheral TM1 regi…
Translating User Perspective into Spatial Design
2013
A rapid adoption of ICT innovations transforms the context of human activities and collaboration, the educational settings included. The context change at the same challenges the traditional spatial design paradigm calling for tools and approaches that are applicable to ICT enhanced practices. We take here an ecological approach presenting a work in progress in which we aim to develop a tool for capturing and translating user perspective in order to design innovative learning spaces for vocational education; the case is one of practical nursing. We apply a combination of quantitative and qualitative methods. By focusing on the local practices and user perspective in cultural transition, we …
L’habitat durable sans l’habiter ? Fabrique de la densité en Bourgogne
2017
In 2009 and 2010, in order to combat the urban sprawl, the Grenelle Environment sets out urban density as a public policy issue. This notion builds on a modus operandi of an urbanization regime that includes both the environmental and the participatory dimensions in its approach. This injunction of sustainability is there implemented through a range of standards, rules and procedures, while the stakeholders in urbanism strive to arrange the experience of inhabiting. But how does this apparatus take the test of reality into account? Based on a qualitative research carried out from 2012 to 2015 on urban planning projects intended to increase density in urban and suburban areas in Burgundy, th…
From Analysis to Formulation of Strategies for Farm Advisory Services (Case Study: Valencia – Spain). an Application through Swot and Qspm Matrix
2019
Abstract European agriculture should meet new increasing internal and contextual challenges. For example, the reform of the Common Agricultural Policy in 2003 introduced the cross-compliance, among other novelties, as compulsory for farmers. To better meet this and other requirements, Member States had to set up the so-called Farm Advisory System, operational across the European Union in 2007. From a sample of actors involved in the provision of farm advisory services in the region of Valencia (Spain), the present study aimed to identify the most appropriate strategies to implement such services. SWOT method has been applied to examine the internal and external environment. Based on this di…

Simulation and validation of urban dynamics with cellular automata
2018
Cet article, rédigé en 2008, présente les évolutions importantes la plateforme SpaCelle pour simuler l'évolution d'un espace à l'aide d'automate cellulaire. En particulier, la version 5 permet la structuration multi-couches des cellules pour gérer la dynamique de plusieurs variables définies sur un maillage. Elle permet aussi d'utiliser des cellules de type linéaires ou ponctuelles à travers des couches de type réseau. Les différentes couches ont leur propre dynamique et les règles peuvent faire interagir les couches entre elles. Ces fonctionnalités avancées ont permis de construire un nouveau modèle sur l'évolution de l'agglomération rouennaise plus proche de la réalité terrain en utilisan…
Hydrogen plasma induced photoelectron emission from metal surfaces
2018
Low temperature hydrogen plasmas are strong sources of vacuum ultraviolet radiation. The properties of laboratory plasmas can be influenced by surface processes induced by photons with their energies exceeding the surface work function of the wall material. In this work, the plasma induced photoelectron emission has been studied with different ion sources. The emission depends on the mechanical design of the plasma device, plasma heating method and the discharge power (density). Parametric studies include the quantifying of the emission from different metal surfaces, commonly used as plasma facing materials in ion sources, as well as alkali metal covered surfaces. Experimental studies sugges…
