Latest results from ALICE
In this paper selected results obtained by the ALICE experiment at the LHC
will be presented. Data collected during the pp runs taken at sqrt(s)=0.9, 2.76
and 7 TeV and Pb-Pb runs at sqrt(s_NN)=2.76 TeV allowed interesting studies on
the properties of the hadronic and nuclear matter: proton runs gave us the
possibility to explore the ordinary matter at very high energy and up to very
low pt, while Pb-Pb runs provided spectacular events where several thousands of
particles produced in the interaction revealed how a very dense medium behaves,
providing a deeper picture on the quark gluon plasma(QGP) chemical composition
and dynamics.Comment: Proceeding of the Conference "New Trends in High Energy Physics",

Results on ultra-peripheral interactions in Pb-Pb and p-Pb collisions in ALICE
Ultra-relativistic heavy ions generate strong electromagnetic fields which
offer the possibility to study -nucleus and -proton
interactions at the LHC in the so called ultra-peripheral collisions (UPC).
Here we report ALICE results on J/psi photoproduction measured in Pb-Pb
collisions at = 2.76 TeV and in p-Pb collisions at
= 5.02 TeV.Comment: Presented at EDS Blois 2013 (arXiv:1309.5705

Study of neutrino induced upgoing muon energy
An estimate of the energy of neutrino-induced muons in MACRO is provided by a multiple Coulomb scattering measurement. The MACRO original upward-muon data sample has been subdivided according to the reconstructed muon energy. The results are interpreted in terms of neutrino oscillation

Soft QCD and Diffractive Physics at Lhc
After a short introduction on the importance of the soft and of the diffractive studies in the understanding of minimum bias events, the main results obtained at LHC are discussed. This overview includes identified particle and inclusive measurements, minimum bias and underlying events, all of them shedding light on the soft process production mechanisms. The results of the inelastic cross-section measurements obtained by the LHC experiments and their compatibility are discussed together with the models used to extrapolate the data at low diffractive masses. A review of the most recent diffraction results is presented, showing the different approaches used by the LHC experiments, relying on different experimental techniques. The combination of the results obtained by ALICE, ATLAS, CMS, LHCb and TOTEM provides a wide sample of informations, covering an unprecedented pseudorapidity range. A detailed comparison between the obtained results is shown, followed by a critical discussion on the still existing discrepancies between the experimental data and the Monte Carlo used at LHC to simulate soft and diffractive physics
Il problema della temporalitĂ nella filosofia di Edmund Husserl
La fondazione della logica e la tematizzazione dell'intenzionalitĂ come vivificazione di un contenuto inerte. Insufficienza di una tale spiegazione e conseguente approfondimento della dimensione temporale della coscienza. L'abbandono dello schema apprensione-contenuto d'apprensione. Il flusso assoluto costitutivo di tempo come intenzionalitĂ originari
