Pinacoteca del Museo Civico di Rieti

"La ristrutturazione della Pinacoteca trae fondamento dalla sua storia, da quella dell'edificio che la ospita, insieme alla riconsiderazione del suo contesto socioculturale. Il nuovo ordinamento si basa su un progetto scientifico e un progetto architettonico strettamente legati tra loro: uno ha prodotto l'altro, uno è precisato dall'atro" (G. Rosa

Effects of ultrasonic treatments in orange juice processing

[EN] The influence of ultrasound and conventional heating under different processing conditions on the inactivation and potential subsequent growth of micro-organisms in orange juice was investigated. Although a limited level of microbial inactivation (<= 1.08 log CFU ml(-1)) was obtained by selected batch ultrasonic treatment: 500 kHz/240 W for 15 min, microbial growth was observed in the substrate following 14 days of storage at both refrigeration (5 degrees C) and mild abusive (12 degrees C) temperatures. The presence of pulp in the juice increased the resistance of micro-organisms to ultrasound. After continuous ultrasonic treatments at flow rates of 3000 L h(-1) negligible reductions of microbial counts were obtained. No ultrasound-related detrimental effects on the quality attributes of juice (limonin content, brown pigments and colour) were found. Therefore, to prevent the development of food-borne pathogens in orange juice it will be necessary to combine ultrasound with other processing methods with greater antimicrobial potency, as well as to achieve a very low initial concentration of bacteria, yeast and moulds in the juice. Such combinations will require further exploration of important synergistic effects that are relevant for industrial use. In this regard, the use of ultrasound in combination with mild heating for industrial use is discussed. (c) 2006 Elsevier Ltd.

Tests génétiques préimplantatoires : enjeux légaux et éthiques dans la pratique clinique [Preimplantation genetic testing: legal and ethical aspects in clinical practice]

In Switzerland, since modifications of the law regulating reproductive medicine introduced the 1rst of September 2017, preimplantation genetic testing (PGT) has been legalised. Infertile couples undergoing in vitro fertilization (IVF) can benefit from this technology by detecting which embryos are aneuploid (ie abnormal number of chromosomes, PGT-A). This is performed in order to transfer euploid embryos (normal number of chromosomes) and to optimise success, though data are limited. Couples at risk of transmitting a severe monogenic disease or unbalanced translocation can undergo PGT for monogenic disease or chromosomal structural rearrangements (PGT-M/SR). These tests are subject to strict legal criteria. Their clinical application needs to be approved through a multidisciplinary approach taking into account legal and ethical issues while respecting the autonomy of the couples

La geometria nascosta: Frank L. Wrigt details

Questa lettura non deve interessare solo gli allievi, ma anche e soprattutto il corpo docente, che deve sviluppare la sua preparazione attraverso un costante aggiornamento culturale e deve riuscire ad instaurare un rapporto tale con l'allievo da fargli apprezzare e capire il valore e l'importanza dell'architettura, che non può essere confinata in un angolo ammuffito dei nostri interessi primari, ma deve contribuire a migliorare il nostro sistema di vita
