AIM The aim of this study was to compare the clinical outcome of submerged vs. non-submerged tapered implants placed into fresh extraction sockets. MATERIALS AND METHODS A prospective, controlled, multicenter, randomized, clinical trial has been performed in two centers in Rome and Torino (Italy). Thirty healthy patients were recruited according to the following inclusion criteria: need for a...

The use of impinging liquid jets in electronics thermal management is attracting some consideration due to their very high heat transfer coefficients, hot spot targeting capabilities and moderate hydraulic power requirements. In this investigation an experimental study of the cooling capabilities of impinging water jet arrays is presented. Of particular interest here is the influence that the i...

As excess water is discharged from a high dam, low frequency noise (air pulsation lower than 10 Hz, LFN) is generated and propagated in the surrounding areas, causing environmental hazards such as the vibration of windows and doors and the discomfort of local residents. To study the generation mechanisms and key influencing factors of LFN induced by flood discharge and energy dissipation from a...

An experimental and “numerical study (first part of this study) was carried out to investigate the solidification process in a copper continuous strip casting process. The model has been tuned by results (i.e. cooling water flow measurements, temperature measurements metallographic analysis). Further, have used possibility improved productivity. In report (second pattern molten during as manufa...

This thesis reviews observational and theoretical work on the equatorial deep jets and work related to the study of the role of the horizontal Coriolis parameter. Most existing analytical models interpret the equatorial deep jets as either low frequency, long Rossby waves or stationary, long Kelvin waves generated at or near the ocean surface. These models are unable to answer the question of h...
