CO(2)-water supercritical mixtures: Test of a potential model against neutron diffraction data
2007
Abstract A neutron diffraction experiment on supercritical mixtures of water and CO 2 at two concentrations is presented. Data are analyzed within the EPSR framework and the water–water and water–CO 2 radial distribution functions are compared with those calculated by a Molecular Dynamics simulation performed by using the TIPS2 and EPM-M potential models for water and CO 2 respectively. It is found that the Molecular Dynamics simulation reproduces the overall shape of the site–site radial distribution functions, although missing a few subtle changes brought along when the CO 2 concentration is increased.

ANAPLASTIC THYROID CANCER: A CASE SERIES WITH A WIDE SPECTRUM OF TREATMENT IN EMERGENCY
2019
Anaplastic thyroid carcinoma (ATC) is one of the most aggressive malignancies of the neck, and for the majority of these patients the cause of death is a compromised airway, metastatic disease, superior vena cava syndrome, asphyxiation, or exsanguination. In case of the airway being compromised, emergency treatment is mandatory but not well defined. We report 4 different kinds of acute presentation of complications. Anaplastic thyroid cancer; diagnostic, clinical and prognostic indication, evaluation of choice of treatment are discussed. The spectrum of treatment varies from observation and preservation of the airway from a tracheostomy to extensive surgery. When a potentially curative rese…

Il carcinoide bronchiale: revisione della letteratura recente
2005
Objective: Yo evaluate methods of diagnosis and treatment, and the long term survival of patients treated for bronchial carcinoid tumor by the review of recent literature. Methods: The Authors conducted a retrospective study on internet-based-evidence of patients treated for bronchial car-cinoid tumor since 1993 to 2004. Symptoms, diagnosis, operative approach and survival were assessed. Conclusions: On the basis of the review of the international literature, the Authors affirm that the 5 and 10-year probability of survival are closely linked to the histological type of carcinoid, to the presence of nodal and distant metastasis. Owing to the potential malignancy of these tumours, preference…
Quality-control procedure for dry-process rubberised asphalt mastics
2019
Crumb Rubber (CR) can be incorporated into asphalt mixes via the dry process by directly adding CR into the mixer together with other asphalt mixture’s components, or with the wet process where the CR is used as a bitumen modifier. While the wet process allows an accurate monitoring of the interaction between CR and bitumen, the lack of control represents a main issue in the dry process. In fact, in the latter the CR particles keep swelling during hauling and possibly also after paving operations, often causing workability issues and premature failures. This study wants to provide a methodology that could help quality control procedures of bitumen/filler/rubber systems during mixing, haulin…
[Optimization of systemic treatments for chronic plaque psoriasis. Recommendations for switching and transitioning.]
2014
The aim of this study was to provide practical recommendations for optimizing the use of conventional and biological systemic treatments for moderate-severe chronic plaque psoriasis, particularly in case of transitioning and switching.A total number of 147 dermatologists from 33 different countries including Italy achieved consensus in providing practical recommendations for the use of conventional and biological treatments for moderate to severe psoriasis based on systematic literature review and/or expert opinion.In general, the continuous treatment regimen should be preferred in order to achieve a complete and long-term control of psoriasis. However, the treatment could be stopped or the…

Rotational collisional line broadening at high temperatures in the N2 fundamental Q-branch studied with stimulated Raman spectroscopy
1986
Self broadened N 2 Q-branch spectra are measured by high resolution stimulated Raman spectroscopy in the pressure region 0.25-1.9 atm. and in the temperature range 295-1310 K. Non additivity of the Q(J) components due to line overlap arising in the highest pressure range explored is carefully taken into account. Excellent fit of the whole spectra is thus obtained for each pressure with linearly density-dependent line widths. Semi-classical calculations of the line-broadening coefficients lead to consistent values with all the measured ones. These calculations are extended to higher J values and to higher temperatures (up to 2500 K). At last, a simple phenomenological model based on a polyno…
Predictive Model for Cut-Edge Corrosion of Galvanized Steels
2006
A numerical model for the electrochemical behavior of cut-edge of galvanized steels is proposed. Some experimental data of current densities above cut-edge immersed in a 0.03M NaCl solution have been measured, using a scanning vibrating electrode technique, and compared with some simulated ones. A good fit has been obtained. The model geometry has been modified by decreasing the electrolyte thickness in order to tend towards an atmospheric corrosion case; such situation that is not easily accessible by electrochemical studies. Three regions can be distinguished according to the efficiency of the galvanic coupling to protect steel.
