No full textMonitored Drift Tubes (MDT), filled with a mixture of Ar-CO2 at 3 bar pressure, are used as tracking devices for the ATLAS muon spectrometer at the Large Hadron Collider. MDT chambers were tested at the Roma Tre cosmic test site with the final version of front-end electronics, which provides information about the collected charge through a Wilkinson ADC. We present an analysis of the signal and timing characteristics in cosmic ray events, and of charge-dependent time response of the MDTs. A method to improve the spatial resolution of MDT chambers using the ADC information to correct the time response was developed. The procedure is based solely on the data from the MDT chamber itself. The results are compared with a simulation of the tube response with the Garfield program. (C) 2004 Elsevier B.V. All rights reserved
Situation Awareness and Environmental Factors: The EVO Oil Production
No full textThe paper considers simulation results for a supply network, that deals
with Extra Virgin Olive (EVO) oil production, an activity that is typical of Southern
Italy. The phenomenon is studied by differential equations, that focus on goods on
arcs and queues for the exceeding goods. Different numerical schemes are used for
simulations. A strategy of Situation Awareness allows defining a possible choice
of the input flow to the supply network. The achieved results indicate that Situa-
tion Awareness permits to find good compromises for the modulation of production
queues and the optimization of the overall system features
Evaluation of T cell subsets in Behçet's syndrome using anti-T cell monoclonal antibodies.
No full textSeveral immunological abnormalities have been described in Behçet's syndrome, the multisystem disease characterized by the triad of relapsing iridocyclitis with recurrent oral and genital ulcerations. In the present study we have evaluated T cell subsets in the peripheral blood of patients suffering from Behçet's syndrome, using a panel of anti-T cell monoclonal antibodies. When compared with normal subjects, patients with Behçet's syndrome show a discrepancy between the number of T3+ cells and those forming rosettes with sheep erythrocytes, a significantly higher number of T4+ and T8+ double labelled cells, as well as of T6+ lymphocytes in the peripheral blood. The percentage of T8 T lymphocytes is increased, thus lowering the T4+/T8+ cell ratio. The results of this study indicate that a complex imbalance of T cell subsets is present in Behçet's syndrome and give a rationale for possible treatment of these patients with immunomodulators
