The dispersion of nitrogenous compounds and heavy metals into the environment is frequent during mining activities. The effects of nickel (Ni) and cobalt (Co) on denitrification of simulated mine waters were investigated in batch bioassays and fluidized-bed reactors (FBRs). At pH 7, batch tests revealed that Co did not exhibit inhibition on denitrification(More)
The OPERA neutrino experiment at the underground Gran Sasso Laboratory has measured the velocity of neutrinos from the CERN CNGS beam over a baseline of about 730 km with much higher accuracy than previous studies conducted with accelerator neutrinos. The measurement is based on high-statistics data taken by OPERA in the years 2009, 2010 and 2011. Dedicated(More)
Beams of Carbon nuclei are now in use or planned to be used in various centers for cancer treatment around the world. The knowledge of the fragmentation of Carbon nuclei when they interact with the human body is important for evaluating of the spatial profile of their energy deposition in the tissues, hence the damage to tissues neighbouring the tumor. To(More)
The OPERA experiment, designed to conclusively prove the existence of ν µ → ν τ oscillations in the atmospheric sector, makes use of a massive lead-nuclear emulsion target to observe the appearance of ν τ 's in the CNGS ν µ beam. The location and analysis of the neutrino interactions in quasi real-time required the development of fast computer-controlled(More)
The OPERA experiment has been designed to observe an unambiguous signal of ν µ → ν τ oscillation in the parameter region indicated by previous experiments in the atmospheric sector. It is based on the nuclear emulsion technique to directly observe among the neutrino interaction products the track of a τ lepton produced by a ν τ appeared in a ν µ beam. The(More)
This paper presents an intended test setup and methodology for testing micro-controller SoCs against the effects of ionizing radiations. The method structure is based on a modular test sequence for test definition, coding, validation and setup. It will be illustrated by the relevant example of a microcontroller solution including lockstep options. Our(More)
During the years 1994–97, the emulsion target of the CHORUS detector was exposed to the wide-band neutrino beam of the CERN SPS of 27 GeV average neutrino energy. In total about 100, 000 charged-current neutrino interactions with at least one identified muon were located in the nuclear emulsion target and fully reconstructed, using newly developed automatic(More)
The way a charm-quark fragments into a charmed hadron is a challenging problem both for the theoretical and the experimental particle physics. Moreover, in neutrino induced charm-production, peculiar processes occur such as quasi-elastic and diffractive charm-production which make the results from other experiments not directly comparable. We present here a(More)
