[en] We review the current status of neutrino oscillations based on the results of recent experiments using conventional beams and nuclear reactors as neutrino sources.

[en] In this paper the concept of the betatron tune and the techniques to measure it are discussed. The smooth approximation is introduced along with the terminology of betatron oscillations, phase advance and tune. Single particle and beam spectra in the presence of synchro-betatron oscillations are treated with emphasis on the consequences of sampling the beam position. After a general presentation of various kinds of beam position monitors and transverse kickers, the time domain and frequency domain analysis of the beam response to a transverse excitation are discussed and several methods and applications of the tune measurements are listed

[en] The cost of biodiesel is nowadays affected by the cost of the raw materials, because the currently used method of preparation requires highly refined vegetable oils containing very low amounts of free fatty acids and moisture. Alternatively, less expensive technologies are possible using heterogeneous catalysts. In the present paper examples of these new technologies, based on the use of heterogeneous catalysts, in the production of biodiesel are described and discussed.

[en] At DAPHINE luminosity measurements are performed by detecting the photons from single Bremsstrahlung at the two interaction points. Set up and measurement method are presented with special emphasis on background subtraction schemes, error evaluation and machine related issues

[en] An immunoassay method for testosterone was developed in which the binding reaction is monitored by a chemiluminescent tracer (testosterone-3-carboxymethyloxime-aminobutyl-ethyl isoluminol; T-3cmo-ABEI). When undergoing oxidation at high pH values by a microperoxidase-hydrogen peroxide system, the chemiluminescent tracer emits light with a relative high quantum efficiency (detection limit = 0.5 fmol). A heterogeneous immunoassay, using dextran-coated charcoal for separation of bound and free forms of the ligand, was developed and assessed, always when performing parallel studies in RIA. Computer analysis of the results demonstrated that the performance of the chemiluminescent immunoassay (LIA) was entirely comparable to that of RIA in terms of sensitivity, precision, specificity and accuracy. Plasma samples of normal subjects and of patients affected by disorders of androgen secretion were assessed by both the procedures (RIA and LIA) and the results obtained using the two methods were superimposable (n=33; r=0.97). Aliquots of the incubation medium of a bioassay for serum hLH measurements (RICT) were also measured by the LIA procedure and by RIA - the results were similar. The proposed LIA method for testosterone, which does not require radioactive material, appears fully suitable for clinical purposes. (author)

[en] The beam diagnostics network of DAΦNE, the Frascati Φ-factory, includes more than 110 beam position monitors divided between button monitors and striplines. The shape of the vacuum chamber changes along the accelerator implying several different geometries for these monitors. Moreover, in the two interaction regions of the collider where the electron and positron beams pass into the same chamber, a six-button configuration has been used. A bench calibration of each family of BPMs and striplines is being performed. A polynomial correction function has been derived by fitting the calibration results. An analytical-numerical analysis of the buttons'' geometry has been done in order to compare the experimental with the theoretical results. copyright 1997 American Institute of Physics

[en] Multibunch operation in high current storage rings like DAΦNE can be seriously limited by coupled bunch oscillations driven by resonant e.m. fields trapped somewhere along the vacuum chamber. The design of each vacuum chamber component aims to keep the beam coupling impedance below the values for which multibunch instabilities can be controlled by feedback systems. The impedance of some of the most critical devices has been measured and a summary of the obtained results is presented. (author)

[en] SHiP (Search for Hidden Particles) is a newly designed fixed target facility, proposed at the CERN SPS accelerator, with the aim of complementing searches for New Physics at LHC by searching for light long-lived exotic particles with masses below a few GeV/c². The sensitivity to Heavy Neutrinos will allow for the first time probing a region of the parameter space where Baryogenesis and active neutrino masses and oscillation could also be explained. A dedicated detector, based on OPERA-like bricks, will provide the first observation of the tau anti-neutrino. Moreover, ν_τ and ν̄_τ cross-sections will be measured with a statistics 1000 times larger than currently available data and will allow extracting the F4 and F5 structure functions, never measured so far. Charm physics studies will be performed with significantly improved accuracy with respect to past experiments. (paper)
