AbstractAbstract
[en] A small steam expander reciprocating engine is proposed for the conversion and utilization of low-grade heat resources of different nature, such as geothermal, solar, and recovery of waste heat. The engine, still to be developed for production, should be able to work with small flow rates and low upper temperature (100–150 °C), rejecting heat at a level still interesting for heating or cooling (with an absorption machine), that is, 50–80 °C. The device should be compact, simple and capable of easy control in order to match electric production and loads. The thermodynamic model uses real-fluid and real-cycle assumptions. It includes a heat transfer model for non-adiabatic compression and expansion, losses through admission/discharge valves, and the effects of dead space. Quasi-stationary modeling of the system is applied: the results are also compared with those of a dynamic model, working under perfect-gas assumptions. The model allows to calculate and analyze the performance of the system, including its dependence on the main design parameters; it includes a preliminary design, with special reference to valve sizing. The results indicate that the proposed technical solution can be applied and that the performance of the CHP (combined heat and power) system is competitive with respect to other technologies for renewable energies

AbstractAbstract
[en] Thermoluminescence (TL) desemeters, placed about 1 m above the ground in selected outdoor sites, provide a simple tool for the measurement of the dose, due to both natural and man-made radiation, in the environment. Since the radiation doses to be monitored are usually low (0.3 to 0.8 mGy per year) the TL chips required for long-term dose measurements should be more sensitive, stable and inert to extreme climatic variations than those used for other applications. Comparison between the main features of two TL dosimetric materials, LiF:Mg,Ti (TLD-100) and LiF:Mg,Cu,P (GR200A), are reported. The field application was performed during a survey in the island of Pantelleria. (author)

AbstractAbstract
[en] Critical fields in magnetization curves of superconducting granular systems are analyzed by considering the tight link existing between the topological properties and the thermodynamic behavior of superconductors. By modeling these systems through a collection of superconducting grains coupled to their nearest neighbors by means of Josephson Junctions (JJ's), one can show that a lower critical field is determined by shielding currents which open the junctions. Moreover we show that the reversible behavior of the magnetization curves for high fields does not necessarily imply decoupling of the grains. A better understanding of the critical fields for the superconducting granular systems is thus attained

AbstractAbstract
[en] The KM3NeT collaboration started to build a multi-km3neutrino telescope in the Mediterranean Sea. The telescope is composed of two parts: the ARCA detector, optimised for searches for high energy neutrino sources in the Universe, and ORCA, for the determination of the mass hierarchy of neutrinos. ARCA is under construction at the Capo Passero site, Italy, 80 km offshore at a depth of 3500 m while ORCA is located in the Toulon area, France, 40 km offshore at a depth of 2500 m. The basic detection element of the KM3NeT detector is the Digital Optical Module. The module is a pressure resistant glass sphere, containing 31 photo-multiplier tubes. Eighteen modules are arranged in the detection unit, a vertical structure anchored on the sea floor. The detection units are deployed on the sea bed to form a three-dimensional array of optical modules to detect Cherenkov light produced by neutrino-induced muons. In these proceedings preliminary results obtained with the first two detection units of ARCA are presented. The capability to select and reconstruct atmospheric muons is discussed. The dependence of the muon flux with the sea depth is derived, showing that the detector is well calibrated and the systematics are kept under control. (paper)
