Do CEE’s Directives Really Compliance with the Kyoto Protocol? A Case Study: Fuel Consumption of one Toyota’s “Little Genius”
No full textDeveloped Countries that signed the Kyoto Protocol are required to attain the established
limits to the greenhouse gas (GHG) emissions or to pay penalty for the exceeding amount. In order
to comply with the Protocol, CEE strategy is based on capillary information of fuel consumption of
motor vehicles, to be done by producers, coupled to economic incentives to users in order to
encourage ecological choices. The need to standardize the measure of GHG emission, related to the
fuel consumption of a vehicle, allowed the drawing up of a very detailed procedure that includes the
choice of driving simulation on urban and extra-urban cycles.
Many drivers claim that the difference between consumption of their own car and values
declared by the producer is too high; tests performed by experts and published on trade journals
such as Quattroruote (Italy) and Autobild (Germany), also demonstrate this datum; unfortunately
nothing can be done to go against producers as such differences mainly depend on almost
unrealistic car use simulations. Car producers fully respect the 98/69/CE [1] while the 1999/94/CE
[2] is not so carefully followed. Moreover, the presented case study evidences that the board
computer (BC), also currently equipping also
small cars, furnishes false data aiming to
convince driver of fuel consumption that is
lower than the real one. Does this also
happens on other cars? Is it correct that a
consumer must pay an instrument to obtain
misleading advertising
Impianto di illuminazione a LEDs e relativo procedimento per inibire lo sviluppo di organismi biodeteriogeni fotosintetici in ambienti ipogei
No full textE\ stato messo a punto un sistema di illuminazione composto da serie di Led monocromatici di lunghezze d'onda che escludono quelle in grado di attivare la fotosintesi e quindi la crescita di biodeteriogeni che la utilizzano. E' studiato per l'illuminazione di ambienti ipogei di interesse storico artistico, pertanto e' possibile modulare l'intensita' dei singoli Led o gruppi di Led per ottenere una luce in grado di far apprezzare al megloi il colore della zona da illuminare.Puo' comunque essere utilizzato in qualunque ambiente ipogeo anche ad uso civile. I Led sono facilmente sostituibili per ottenere spettri diversi in grado di inibire la crescita di diversi biodeteriogeniThe invention relates to the field of illumination and in particular concerns a LED lighting system,
to be used for illuminating hypogeal environments, which is able to trigger no photosynthetic reactions
and, consequently, to hinder the development of photosynthetic biodeteriogen organisms, as well as a
process for inhibiting the growth of said organisms

Preliminary Study to Set up a Non Destructive In Situ Method to Monitor Soluble Salts Content in Stone Materials; The Usefulness of a Multivariate Approach
No full textNew equipments and procedures to monitor in situ soluble salts content in stone materials were set up. They base on the extraction, by flowing ultrapure water, of soluble salts from stone surfaces and on the continuous registration of the real-time response of a conductometric probe; on the final collected solution, conductivity measure and analysis of anions by ionic chromatography can be performed in laboratory. A correlation between the signal obtained in situ and the chromatographic data was looked for; satisfying results were obtained but further investigation are needed in order to take into account all the involved parameters/variables and to extract the most significant index from the signal curve. It must be stressed that the actual normative on Cultural Heritage is scarce and in some case doesn't ensure a fully correct analytical procedure; anyway we compared our method with that indicated in the UNI11087. Surely a multivariate approach will be of help to optimize both the equipment and the procedure. The engineering of the apparatus must be improved too, so the presented results must be considered preliminary
