Nella mia fine è il tuo inizio: il legame paradossale
No full textIl legame educativo è paradossale in quanto è volto alla sua estinzione: gli educatori e i pedagogisti devono porsi, fin dall'inizio della creazione del rapporto educativo, nella prospettiva di lasciar andare l'altro, promuovendo costantemente la sua autonomia
Moisture detection in wood and plaster by IR thermography
No full textin the last decade ,many research have been carried on the application of IRT to detect moisture in the materials of historical buildings, but only few studies are comprehensive of IRT application on wood. The thermal characteristics of timber are highly different from the porous materials ones; particularly, the thermal capacity of wood is lower than bricks, stone and mortars. LAboratory researchers and scientific literature determined that the water content detection in porous materials is more related to the evaporation rate of the surfaces and the presence of soluble salts than to the absorption capability of the materials. Moreover a corretaltion between moisture content, evaporation and boundary conditions, was studied by analyzing evaporation fluxes at different environmental conditions and water content. Because of the lower heat capacity of the timber, the thermographic shot aftern the heating can be affected by the influence of water presence. Laboraotry tests and study cases shoe the advanteges and limit of IRT techniques, and the results obtained permit the comparison between the different heating system applied
Hall mobility in doped Si:H,Cl films.
No full textThe Hall mobility μH in phosphorus- and boron-doped Si:H, Cl films was measured in the temperature range 130–300 K. The conductivity is markedly influenced by the doping, and the activation energies of both the Hall mobility and the conductivity as functions of the temperature are much lower in doped samples than in undoped samples. The process tends to become unactivated at higher doping levels
Abitare la situazione: essere presenza
No full textLe situazioni educative quotidiane si presentano in un tempo, uno spazio e una corporeità specifiche: è a partire da queste condizioni precise che l'educatore si colloca ed esprime la sua presenza. Si tratta di stare in ascolto delle situazioni contingenti, imparando ad "esserci" secondo le modalità proprie che sgorgano in quel contesto. Per l'educatore ciò significa imparare a considerare la propria presenza come un imprescindibile di cui "servirsi", nutrendo quindi un'alta consapevolezza interiore
Evaluation of density of states distribution in amorphous silicon films by photoconductivity measurements
No full textDensity of gap states distribution of amorphous silicon films has been investigated by means of photoconductivity measurements carried out as a function of the temperature
PHOTOCONDUCTIVITY MEASUREMENTS AS A TOOL FOR THE EVALUATION OF THE DENSITY OF STATES IN AMORPHOUS-SILICON
No full textPhotoconductivity measurements as a tool for the evaluation of the density of states in amorphous silicon
No full textPhotoconductivity measurements as a function of the temperature and light intensity were carried out on samples of hydrogenated and halogenated silicon films. The samples were deposited by r.f. glow discharge starting from a mixture of silicon tetrachloride and hydrogen. Experimental data were analysed by using a theoretical model which assumes a density of states distribution having two exponential band tails and two gaussian distribution of states in the mobility gap. The model predicts a dependence of the photoconductivity as a function of the light intensity which agrees very well with the experimental on
