Didattica e teoria dell'apprendimento nelle opere di Renzo Titone

La presente ricerca desidera investigare il pensiero didattico del professor Renzo Titone, studioso di levatura internazionale che operò più assiduamente negli Stati Uniti e in Italia. Il discorso maggiormente noto di Titone si articola nel vasto campo della linguistica, intesa nell’accezione più ampia che è possibile attribuirle. Ma l’originalità del nostro trascende questa disciplina, pur applicandosi ad essa, in quanto egli cercò un modello che potesse funzionare universalmente nel processo di insegnamento-apprendimento, un modello universale che spiegasse il processo di apprendimento di ogni individuo e fondasse così il procedere dell’insegnamento, un modello matetico che fondasse la didattica, un modello sia analitico di tipo diagnostico sia operativo applicabile alla didassi.The objective of this research is to investigate Renzo Titone’s didactic theory. Titone was a famous international professor for a long time, from 1960 to 2000. One of Titone’s foundamental points, that this research would like to illuminate, is a general didactic theme; actually at present Titone is more famous for his psycholinguistic studies, but he worked a lot in the field of general didactic and education. The results could illuminate a man who innovated the didactic view in the past and who can also innovate it in the present

Tests of cosmic ray radiography for power industry applications

In this report, we assess muon multiple scattering tomography as a non-destructive inspection technique in several typical areas of interest to the nuclear power industry, including monitoring concrete degradation, gate valve conditions, and pipe wall thickness. This work is motivated by the need for radiographic methods that do not require the licensing, training, and safety controls of x-rays, and by the need to be able to penetrate considerable overburden to examine internal details of components that are otherwise inaccessible, with minimum impact on industrial operations. In some scenarios, we find that muon tomography may be an attractive alternative to more typical measurements.Comment: LA-UR-15-2212

Measurement of Scintillation and Ionization Yield and Scintillation Pulse Shape from Nuclear Recoils in Liquid Argon

We have measured the scintillation and ionization yield of recoiling nuclei in liquid argon as a function of applied electric field by exposing a dual-phase liquid argon time projection chamber (LAr-TPC) to a low energy pulsed narrow band neutron beam produced at the Notre Dame Institute for Structure and Nuclear Astrophysics. Liquid scintillation counters were arranged to detect and identify neutrons scattered in the TPC and to select the energy of the recoiling nuclei. We report measurements of the scintillation yields for nuclear recoils with energies from 10.3 to 57.3 keV and for median applied electric fields from 0 to 970 V/cm. For the ionization yields, we report measurements from 16.9 to 57.3 keV and for electric fields from 96.4 to 486 V/cm. We also report the observation of an anticorrelation between scintillation and ionization from nuclear recoils, which is similar to the anticorrelation between scintillation and ionization from electron recoils. Assuming that the energy loss partitions into excitons and ion pairs from $^{83m}$Kr internal conversion electrons is comparable to that from $^{207}$Bi conversion electrons, we obtained the numbers of excitons ($N_{ex}$) and ion pairs ($N_i$) and their ratio ($N_{ex}/N_i$) produced by nuclear recoils from 16.9 to 57.3 keV. Motivated by arguments suggesting direction sensitivity in LAr-TPC signals due to columnar recombination, a comparison of the light and charge yield of recoils parallel and perpendicular to the applied electric field is presented for the first time.Comment: v2 to reflect published versio
