Rethinking Philosophy
No full textCan philosophy still be fruitful, and what kind of philosophy can be such? In particular, what kind of philosophy can be legitimized in the face of sciences? The aim of this paper is to answer these questions, listing the characteristics philosophy should have to be fruitful and legitimized in the face of sciences. Since the characteristics in question demand that philosophy search for new knowledge and new rules of discovery, a philosophy with such characteristics may be called the ‘heuristic view’. According to the heuristic view, philosophy is an inquiry into the world which is continuous with the sciences. It differs from them only because it deals with questions which are beyond the present sciences, and in order to deal with them must try unexplored routes. By so doing, when successful, it may even give birth to new sciences. In listing the characteristics that philosophy should have, the paper systematically compares them with classical analytic philosophy, because the latter has been the dominant philosophical tradition in the last century.Can philosophy still be fruitful, and what kind o

Città fragili piccole e medie. Nuove prospettive di sostenibilità per il progetto tecnologico‐ambientale
No full textIl paper restituisce alcune evidenze emerse da ricerche condotte dagli autori sugli spazi non costruiti di città piccolo‐medie abruzzesi caratterizzate da fragilità demografico‐economiche, e da criticità indotte dai cambiamenti climatici, culturali, geomorfologici e sociali. Fra le tendenze trasformative spesso in atto sugli spazi urbani aperti si rilevano o interventi dall’alto, eccessivamente generalisti/standardizzati, oppure azioni dal basso, esclusivamente specializzate/personalizzate. Emerge così la necessità di una sinergia fra universal e user centred vision che permetta di ripensare lo spazio non costruito della città in modo integrato, come un’interfaccia regolativa‐abilitante. Un sistema di spazi che è in grado di ricondurre le sfide della sostenibilità urbana entro una più ampia declinazione relazionale e connettiva fra risorse, spazi, abitanti, culture e forme di produzione locali. Tale sfida appare attuabile in modo particolare nelle città piccole e medie, per via della dimensione contenuta degli insediamenti, della permanenza di relazioni durature fra spazio collettivo, individui e società e per le condizioni socio‐culturali idonee a favorire processi di adattamento. Questi punti di forza potrebbero però perdersi per via della ridensificazione urbana che inizia oggi a coinvolgere anche piccole e medie città. Il modello integrato d’intervento che emerge da queste riflessioni, delinea un orizzonte progettuale tecnologico‐ambientale per agire su due aspetti rilevanti: rendere misurabili le qualità dello spazio aperto attraverso le sue capacità di miglioramento delle interazioni tra benessere degli utenti, spazio collettivo e attrezzature urbane; riequilibrare la qualità degli spazi aperti in senso transcalare, superando la logica di intervento per parti e prediligendo scenari adattivi relazionali e connettivi fra tecnologie, natura, individui e società
High-temperature electrical conductivity of FeTiO3 and ilmenite.
No full textResistivity measurements have been carried out on FeTiO3 and the mineral ilmenite to characterize these materials in terms of oxygen exchange in the gas phase. These measurements were obtained in the temperature range 400-1273 K and in the oxygen partial pressure range 0.5-101.3 Pa. The activation energies of conductivity were found in the range 0.10 +/- 0.01-0.40 +/- 0.01 eV for FeTiO3, and 0.13 +/- 0.01-0.21 +/- 0.01 eV for ilmenite, independent of the oxygen fugacity. FeTiO3, which behaves as p-type semiconductor, shows a sigma proportional to(P-o2)(1/n) experimental dependence with n = +4, supporting an oxygen-exchange process based mainly on the formation of singly negative metal vacancies. Under the same conditions, the resistivity measurements carried out on ilmenite indicated that the sample conductivity was independent of the oxygen partial pressure. This is to be expected if the concentrations of electrons and electron defects are much larger than those of the ionic defects. In this case, the disorder of electrons is not influenced by small deviations from ideal stoichiometry
Defining pedestrian's visual adaptation field under night lighting in Venice
No full textPedestrian areas use lighting systems with output at the mesopic level, which is situated between the photopic and scotopic. Studies have shown surrounding luminance effect on peripheral vision and its magnitude of the effect is larger than that of the foveal luminance. This study aims to examine this proposed model using real night time lighting conditions experienced by pedestrians in dark and narrow alleys and pathways close to water ways in the city of Venice. The eye tracking system and luminance scanning are used to measure such conditions while walking at night. The pedestrians' eye gaze angle data under non uniform background luminance show that peripheral luminance affect pedestrians' adaptation field differently given the pathways' geometry. Luminance adaptation data under mesopic lighting conditions contributes to the lighting system design while meeting the requirements with recommended practice for safe walkway lighting design
Lighting distribution affects pedestrians' sense of security
No full textThe greatest obstacle to a pedestrian's Sense of Security (SoS) is lack of lighting. This research analyzes lighting characteristics which affect a pedestrian's SoS, including how lighting distribution changes perception, to design lighting for night-time walking that maximizes the SoS without increasing energy consumption
MUTUAL CONVERSION OF (BIPB)(2)SR2CAN-1CUNOX HTSCS WITH N=1, 2, 3 - TEMPERATURE AND OXYGEN PARTIAL-PRESSURE DEPENDENCE
No full textThe transformation of the 2223 (n = 3) phase in the 2201 (n = 1) phase by heating the sample in Ar atmosphere was studied. The subsequent cycling of the sample temperature and the oxygen enrichment of the gas phase convert the 2201 (n = 1) phase in the 2223 (n = 3) phase in the presence of the 2212 (n = 2) and Ca2PbO4 compound. The in situ resistivity measurements, T-c values and XRD carried out on the sample confirm these phase changes. The experiment indicates that this process is oxygen dependent at low oxygen partial pressure
