Classification Performance of Virtual Impactor

Medical nebulizer performance: effects of cascade impactor temperature.

BACKGROUND During operation of a jet nebulizer, the temperature of the nebulizer outlet could decrease by more than 10 degrees C, depending on the nebulizer type and operating conditions, such as driving flow rate and fill volume. The droplet size distribution generated from the nebulizer can be measured by a cascade impactor. However, when the cascade impactor is operated at ambient room tempe...

Characterisation and airborne deployment of a new counterflow virtual impactor inlet

A new counterflow virtual impactor (CVI) inlet is introduced with details of its design, laboratory characterisation tests and deployment on an aircraft during the 2011 Eastern Pacific Emitted Aerosol Cloud Experiment (EPEACE). The CVI inlet addresses three key issues in previous designs; in particular, the inlet operates with: (i) negligible organic contamination; (ii) a significant sample flo...

Persian Diasporic Bloggers and Virtual Performance of Cultural Identities

This paper focuses on the concept of consciousness and liminality in the Iranian Diaspora and the way Iranians create digital diasporas where they can practise cultural identities outside the homeland. The discussion elaborates on the concept of traditional dowreh (family/social circle) in the fibre of Persian culture and then illustrates the creation of a virtual dowreh among...
