Ossimoro - Oxymoron

2016

Può l'essenza dell'architettura trovare espressione i due sole parole? L'ossimoro sembra poter soddisfare questa domanda. La figura retorica greca diviene chiave di lettura e, al contempo, obiettivo da raggiungere attraverso il progetto. Forse più che un traguardo assoluto, l'ossimoro dà corpo a quella inquietudine che muta il razionalismo "tout court" in razionalismo esaltato, dove i principi logici sono scardinati dalla componente autobiografica. Can the essence of architecture be expressed in two words? The answer appears to provided by oxymora. The rhetorical Greek figure is both the key to interpret the project and the goal to be reached thanks to the project. More than an absolute goa…

Il complesso parrocchiale di San Gregorio a Cannatello (Agrigento)

2012

Nell'ambito dell'inchiesta che il "Giornale dell'Architettura" conduce sulla realizzazione de "Le chiese della Chiesa" a 50 anni dal Concilio Vaticano II, la rivista segnala quattro recenti progetti, sia italiani che di altre nazioni europee. Tra questi la Chiesa di San Gregorio ad Agrigento, della cui architettura contemporanea viene sinteticamente illustrato il progetto e documentata la sua realizzazione.

In-beam study of the 128, 130Xe nuclei

1981

Abstract The level structure of 128,130Xe has been studied in the (α, 2nγ) and (3He, 3nγ) reactions on enriched Te targets using in-beam γ-ray spectroscopic methods. For both nuclei the existing information about positive-parity level structure was enriched and many new negative-parity two-quasiparticle states were observed. Isomeric states with the half-lives of 63 ± 12 ns in 128 Xe and 4.8 ± 0.5 ns in 130 Xe were found. For collective positive-parity states the interacting boson model, and calculations based on Bohr hamiltonian were compared with the experimental data.

Serotonin control of central dopaminergic function: focus on in vivo microdialysis studies

2008

In this review, the functional interactions between serotonin (5-HT) and dopamine (DA) neuronal systems are discussed with the focus on microdialysis studies in the rodent brain (mainly rats). 5-HT by itself is involved both directly and indirectly via actions on complex neuronal circuitry, in the regulation of DA release through multiple 5-HT receptors, playing a critical role in the development of normal and abnormal behaviours. Recent evidence suggests that dysfunction of dopaminergic and serotoninergic neurotransmitter systems contributes to various disorders including depression, schizophrenia, Parkinson's disease and drug abuse. Here we summarize recent neurochemical works that have e…

High resolution study of the 3ν1 band of SO2

2009

Abstract The second overtone band 3 ν 1 of sulfur dioxide has been studied for the first time with high resolution rotation-vibration spectroscopy. About 3000 transitions involving about 900 upper state energy levels with J max. = 66 and K a max. = 24 have been assigned to the 3 ν 1 band. In the analysis, an effective Hamiltonian taking into account accidental interactions between the vibrational states (3 0 0), (2 2 0), and (0 4 1) was used. The Watson operator in A -reduction and I r representation was used in the diagonal blocks of the Hamiltonian. As the result of analysis a set of parameters reproducing the initial experimental data with the rms = 0.00028 cm −1 was obtained.

Designed surface modes propagating along hyperbolic metamaterials

2013

We report on surface-wave propagation (SWP) that occurs in semi-infinite hyperbolic metamaterials whose optical axis is set in the interface plane. In practice it is implemented by a multi-layered metal-dielectric nanostructure that is cut normally to the layers. Our theoretical analysis shows that various conditions can be designed enabling distinct regimes of SWP. We concluded that hybridization of SWP polarization leads to tighter confinement near the interface as compared with conventional surface plasmon polaritons. By using the finite-element method (FEM), we demonstrate that the fields are enhanced on the walls of metallic films, and thus minimizing significantly its presence inside …

Tuning four-wave mixing through temperature in ethanol-filled photonic crystal fiber

2016

In this paper, continuous tuning of four-wave mixing bands in an ethanol-filled photonic crystal fiber is investigated. A wide tuning range of the parametric bands, from 745 nm to 920 nm (signal) and from 1260 nm to 1710 nm (idler), is achieved through the thermo-optic effect. This corresponds to a frequency tuning range higher than 2000 cm−1; such wide range can be particularly useful in applications that require broadband wavelength conversion, e.g., CARS microscopy. Numerical calculations are in good agreement with experimental measurements.

Precambrian crustal evolution and continental drift

1981

One of the major questions of Precambrian research is whether present-day plate tectonic models can be applied to the evolution of the ancient continental crust or whether the tectonic style suggests a unidirectional and therefore non-uniformitarian development in response to gradual changes in the global thermal regime through time.
