[en] A useful investigation in the study of the dynamic of the normal and pathologic lacrimal drainage is described. 135 little patients have been studied with this technique for the evaluation of the functional assessment of the nasolacrimal drainage. In our opinion Nuclear DCG is the procedure of choice in little babies with epiphora in whom the obstruction cannot be determined with conventional tests

[en] The integration of web technologies and web services has been, in the recent years, one of the major trends in upgrading and developing control systems for accelerators and large experimental apparatuses. Usually, web technologies have been introduced to complement the control systems with smart add-on and user friendly services or, for instance, to safely allow access to the control system to users from remote sites. Despite this still narrow spectrum of employment, some software technologies developed for high performance web services, although originally intended and optimized for these particular applications, deserve some features that would allow their deeper integration in a control system and, eventually, using them to develop some of the control system's core components. In this paper we present the conclusion of the preliminary investigations of a new design for an accelerator control system and associated machine data acquisition system (DAQ), based on a synergic combination of network distributed object caching (DOC) and a non-relational key/value database (KVDB). We investigated these technologies with particular interest on performances, namely speed of data storage and retrieve for the distributed caching, data throughput and queries execution time for the database and, especially, how much this performances can benefit from their inherent adaptability.
