We present the result of a year-long effort to think, design, build, realize, and manage the robotic, autonomous REM observatory, placed since June 2003 on the cerro La Silla, ESO Chile. The various ...aspects of the management and control are here surveyed, with the nice ideas and the wrong dead ends we encountered under way. Now REM is offered to the international astronomical community, a real, schedulable telescope, automatic for the People.

The Rapid Eye Mount (REM) is a 60 cm robotic telescope located at La Silla, Chile. Its Observing Software (REMOS) is constituted by a set of distributed intercommunicating processes organized around ...a central manager. Together they grant the system safety, automatically schedule and perform observations with two simultaneous cameras of user-defined targets, and drive fast reaction to satellite alerts. Subsequent data reduction is left to pipelines managed by each camera.
During the last years, a number of telescopes have been dedicated to the followup of the GRBs. But after the Swift launch, the average observed intensity of the GRBs showed to be lower than thought ...before. Our experience with the robotic 60 cm REM telescope confirmed this evidence, with a large number of lost GRBs. Then, we proposed to study the feasibility of a 4 m fast pointing class telescope, equipped with a multichannel imagers, from Visible to Near Infrared. In this paper, we present the main result of the feasibility study we performed so far.
We performed a neutron scattering study to investigate the dynamical behaviour of water absorbed in Nafion at low hydration levels (λ = 6, λ = moles of water/moles of sulphonic acid sites) as a ...function of temperature in the range 200-300 K. To single out the signal of the confined water, the measurements were performed on samples hydrated with both H

O in the same temperature range. Due to the strong incoherent scattering cross section of hydrogen atoms with respect to deuterium, in the difference spectra the contribution from the Nafion membrane is subtracted out and most of the spectra originates from absorbed water. The estimated dynamical susceptibility exhibits features that resemble those of bulk water. In particular, the spectra display a bump at around 1 meV, possibly related to the α relaxation, the intensity of which is markedly affected by the temperature change. Two features due to the phonon-like collective hydrogen bond network dynamics are visible at approximately 7 meV and 25 meV.
Body piercing indicates the puncturing of a part of the body in which jewelry may be worn. In recent years, oral piercing is increasingly popular especially among young people. Body piercing has to ...be considered as a surgical procedure to all intents and purposes and, as such, has to be performed only by qualified personnel able to assure high standards of professionalism in facilities subject to sanitary inspections.The aim of the present work is to verify what risks patients may be exposed to and what complications may occur after a healthcare professional performs oral piercing.Our retrospective study includes 108 patients (74 males and 34 females) aged between 14 and 39 years, who had oral piercing done 12±4 months earlier. All the patients underwent clinical examination to reveal the possible presence of late complications. After piercing, none of the 108 patients developed widespread complications.Although all patients said they had followed the piercers' instructions, 96% of them reported postoperative local complications such as bleeding within 12 hours of piercing (90%), perilesional edema for 3±2 days after piercing surgery (80%), and persistent mucosal atrophy (70%).
Scar formation is a process consequent to the healing of soft tissues after a trauma. However, abnormal or disturbed collagen production can cause anomalies of the cutaneous surface and textural ...irregularities. In the presence of a depressed scar in deep tissue, we began to use a new simple technique. In the presence of adherent scars, a small incision is performed so that an undermining scissor can enter inside. The entire cicatricial area is undermined on a subcutaneous plane which, by separating the deep scar from the superficial one, completely frees it from the present adhesions so that the existing depression is totally eliminated. In order to avoid the recreation of relapses, stitches formed in a U-shape are made in Nylon or Monocril 2-3/0 are made with a large needle and are placed close together so that a wide aversion is achieved at the margins of the scar and a deep wound closure is obtained by adhering to the undermined tissue. These stitches will then be removed about 2 weeks later.
