The mobilization of an oil bank in a packed bed of glass beads saturated with an aqueous phase has been studied both theoretically and experimentally. The size of the glass beads was varied in the range between 0.5 and 5mm. Two oils (hexadecane and hexane) with viscosities different for an order of magnitude and densities smaller than that of water have(More)
We have studied the interaction of high frequency jet ventilation with cardiovascular pressures and flows. Results in dogs show that the amplitude of all intrathoracic pressures and flows fluctuate with a frequency equal to the difference between the heart rate and ventilator rate. The magnitude of this amplitude variation may be sufficient to obliterate(More)
The mobilization of an oil bank under the combined effect of Bond (N(B)) and capillary (N(C)) numbers, in a packed bed column of glass beads saturated with water, has been investigated. In order to reach the irreducible saturation the experiments have been run with sweeping water velocities outside the range of validity of the Darcy's law. The size of the(More)
The results of catalytic hydrotreating of a commercial mixture of 2,4'-DDT and 4,4'-DDT are reported. Experimental runs were carried out in a batch reactor (300 cm3) at constant hydrogen pressure (PH2 = 20 bar) and temperature. Temperature levels 150, 180, 200 and 230 degrees C were tested. A commercial sulphide Ni-Mo catalyst was adopted. The reacting(More)
Two greenhouse experiments were carried out to analyze the shoot sodium (Na) partitioning, yield, and fruit quality of ‘Cuore di Bue’, a salt-sensitive heirloom tomato (Solanum lycopersicum L.), ungrafted or grafted onto interspecific tomato hybrid rootstocks (S. lycopersicum 3 S. habrochaites) ‘Maxifort’ and ‘Arnold’ in 2009, ‘Arnold’ and ‘Armstrong’ in(More)
The gelation in situ of polymers may be a method for temporarily containing organic solvents and other petroleum derived products, which may enter the subsurface. In order to create gels that are neither toxic to humans nor to the ecosystem, we have investigated on the use of the biopolymer xanthan gum with aluminum as a crosslinking agent. Firstly we have(More)
BACKGROUND/AIMS When an occlusive cover is applied on the skin, the transepidermal water loss (TEWL) is inhibited and the skin moisturises. Upon the removal of the occlusion the water, which accumulated in the skin porosity during the occlusion, evaporates and diffuses outside showing a TEWL rate larger than the basal value, and function of time. The aim of(More)
The remediation of soils contaminated with chlorinated compounds was investigated. The process consists of solvent extraction followed by catalytic hydroprocessing (hydrodechlorination) of the extract phase. A mixture of ethylacetate-acetone-water (E-A-W) was adopted as solvent in the extraction process. Tests of extraction of chlorobenzene from a model(More)
The authors describe a case of undifferentiated pleomorphic sarcoma of the breast occurring in a 50-year-old woman who presented with a palpable mass in her right breast. She first noticed the mass one month previously. Core needle biopsy showed connective tissue including epithelioid and spindle cells. The patient underwent total mastectomy without(More)
Reticulated platelets are the youngest marker of megakaryopoiesis. We monitored 13 haematological patients undergoing autologous peripheral haematopoietic progenitor cell transplantation. We used a flow cytometric method based on thiazole orange platelet staining. Patients showed a fall in reticulated platelet percentage at a mean of 5 days before a nadir(More)
