Indeed, thanks to the showcase, the concentration of particles below 2 µm is divided by 4 and by nearly 60 for particles above 2 µm.
However, when it comes to the showcase itself, the particle concentration reduction is more marked in Bayeux.
Shear and peel stress distribution within the adhesive layer is presented to showcase the presence of stress concentration at the ends of the overlap.

This is in good agreement with prior measurements of the organic acid concentration in air inside the showcase, which revealed very high levels; 140 ppb formic acid and 1020 ppb acetic acid.
The highest indoor concentrations recorded during the autumn and winter periods in the Criminology Museum of the University of Athens (76.5 and 70.5 μg/m3, respectively), whereas comparable high was the average PM concentration in autumn inside the showcase in the Neophytos Doukas Library in Zagori.
"We don't have an Avenue Montaigne or a Bond Street, but Zamalek has a high concentration of up-market stores that showcase talented designers," Ms. Sabet said.
Perhaps the best example of her fierce concentration is "Trading Places" (1983), a showcase at the Equity Library Theatre, which Stroman devised with Jeff Veazey, her lanky dance partner of four years.
Furthermore, the concentration of PM10 and PM2,5 in showcases shows often similar values with the indoor levels indicating that the use of showcases is not always an effective mechanism for reducing the exposure to particles.
Thus, the measures set for the preservation of the embroidery seem effective, given the strong reduction of particle concentration and the cleanroom environment in the showcase.
