Preliminary magnetic resonance relaxometric analysis of Fricke gel dosimeters produced with polyvinyl alcohol and glutaraldehyde
2017
This work describes the preliminary analysis of Fricke gels dosimeters characterized by a new formulation making use of a matrix of polyvinyl alcohol cross-linked by adding glutaraldehyde and analyzed by means of nuclear magnetic resonance relaxometry. In previous optical studies, these gels have shown promising dosimetric features in terms of photon sensitivity and low diffusion of ferric ions produced after irradiation. In this work, we used a portable nuclear magnetic resonance relaxometer to measure the relaxation times (which are important for dosimetric applications) of these gel materials. For this purpose, we performed a study for optimizing the acquisition parameters with a nuclear…
NUCLEAR MAGNETIC RESONANCE RELAXOMETRY AND IMAGING FOR DOSIMETRY WITH AGAROSE FRICKE GEL
2016
Introduction: Fricke Xylenol Gel (FXG) dosimetric system is based on the radiation induced oxidation of ferrous to ferric ions. In this kind of gels it can occur that ferrous and ferric ions diffuse in the gel matrix. To preserve the spatial distribution of the dose from diffusion, Fricke gels must be undergoing measurement within a few hours of their irradiation. Thus, the spatial integrity of the dose distribution in the Fricke gel is maintained. The oxidation of ferrous ions also causes a reduction of the longitudinal nuclear magnetic relaxation time which can be measured by means of nuclear magnetic resonance (NMR) instrumentation. In this work we performed NMR relaxometry and MR imagin…

Sull’inadeguatezza della retribuzione fissata dal C.C.N.L. alla luce dell’art. 36 Cost.
2020
Non può escludersi che il trattamento retributivo determinato dalla contrattazione collettiva, pur dotata di ogni crisma di rappresentatività, possa risultare in concreto lesivo del principio di proporzionalità alla quantità e qualità del lavoro e/o di sufficienza ad assicurare al lavoratore e alla propria famiglia un’esistenza libera e dignitosa (art. 36 Cost.); pertanto, il lavoratore che ritenga inadeguata per difetto la retribuzione contrattualmente prevista ha l’onere di indicare gli elementi da cui tale inadeguatezza risulta, mentre sul giudice che condivida la censura incombe uno specifico onere di motivazione; in tal senso il procedimento di verifica della compatibilità con l’art. 3…
