Rovello bianco, caratterizzazione di un vitigno autoctono campano.
Il “Rovello bianco”, conosciuto localmente come “Greco muscio” nuovo vitigno autoctono campano è stato oggetto di uno studio triennale (2004-2005) considerando il “Fiano” come varietà di riferimento. L’analisi molecolare mediante marcatori micro satelliti (SSR) ne ha stabilito l’unicità del profilo genetico. La valutazione agronomica è stata ottenuta attraverso annuali e sistematici rilievi, effettuati su 50 piante di 5 anni di età, registrando da parte del “Rovello bianco” un più basso vigore vegetativo rispetto al “Fiano” e una buona resistenza alle più diffuse fitopatie. Ben distinta dal vino “Fiano” è risultata invece la componente organica volatile. Principalmente alcoli isoamilici qua…
ANALISI SPERIMENTALE DEL COMPORTAMENTO CICLICO DI NODI DI TRAVI SER E PILASTRI IN C.A.
Results of experimental investigation on cyclic behavior of beam-column joints made up of hybrid steel trussed concrete beams connected to reinforced concrete columns are presented. Specimens are representative of joints in framed structures subjected to seismic actions designed according to current Italian technical standard codes. The aim of the experimental testing was to verify strength capacity and ductility of the connection, focusing both the global behavior and the force transmission mechanisms between steel truss and concrete in the region close to the beam-column joint.
ANALISI TEORICO-SPERIMENTALE DEL COMPORTAMENTO A TAGLIO DI TRAVI PREFABBRICATE RETICOLARI MISTE
An experimental campaign of three-point bending tests on specimens of Hybrid Steel Trussed Concrete Beams (HSTCBs) is presented. The scope of the experiments is the evaluation of the shear strength in the structural typology object of study. Two series of specimens are tested, subjected to positive and negative bending moment, respectively, with the aim to reproduce, in the first case, the condition in the midspan of a beam belonging to a framed structure and, in the second case, the behavior of the beam next to the column where the sign of the bending moment is reversed. The obtained experimental results are interpreted by means of an analytical model for the prediction of the shear resist…
Sedimentation and Fouling of Optical Surfaces at the ANTARES Site
ANTARES is a project leading towards the construction and deployment of a neutrino telescope in the deep Mediterranean Sea. The telescope will use an array of photomultiplier tubes to detect the Cherenkov light emitted by muons resulting from the interaction with matter of high energy neutrinos. In the vicinity of the deployment site the ANTARES collaboration has performed a series of in-situ measurements to study the change in light transmission through glass surfaces during immersions of several months. The average loss of light transmission is estimated to be only ~2% at the equator of a glass sphere one year after deployment. It decreases with increasing zenith angle, and tends to satur…
