Studi epidemiologici sul giallume europeo delle drupacee (ESFY) in impianti peschicoli del veronese

Vengono riportati i risultati di indagini effettuati nel decennio 1995-2004 per il monitoraggio di ESFY in numerosi pescheti della provincia di Verona, nonch\ue8 sulla presenza di psillidi infetti dal patogeno e sulla presenza di piante spontanee, possibili serbatoio d'inoculo per ESFYP nelle stesse aree. E' stato verificato un progressivo incremento della malattia (2% medio di nuove infezioni ogni anno), la presenza di piante spontanee di prugnolo e mirabolano infette e di numerosi individui di Cacopsylla pruni infetti da ESFYP

Energy calibration of CALET onboard the International Space Station

In August 2015, the CALorimetric Electron Telescope (CALET), designed for long exposure observations of high energy cosmic rays, docked with the International Space Station (ISS) and shortly thereafter began to collect data. CALET will measure the cosmic ray electron spectrum over the energy range of 1 GeV to 20 TeV with a very high resolution of 2% above 100 GeV, based on a dedicated instrument incorporating an exceptionally thick 30 radiation-length calorimeter with both total absorption and imaging (TASC and IMC) units. Each TASC readout channel must be carefully calibrated over the extremely wide dynamic range of CALET that spans six orders of magnitude in order to obtain a degree of calibration accuracy matching the resolution of energy measurements. These calibrations consist of calculating the conversion factors between ADC units and energy deposits, ensuring linearity over each gain range, and providing a seamless transition between neighboring gain ranges. This paper describes these calibration methods in detail, along with the resulting data and associated accuracies. The results presented in this paper show that a sufficient accuracy was achieved for the calibrations of each channel in order to obtain a suitable resolution over the entire dynamic range of the electron spectrum measurement
