A seed meter comprises a plastic casing defining a volumetric compartment and a singling compartment. The portable device connects to a cellular telephone, thus providing wireless connection to the internet via a host computer which runs a browser, that takes information received from the Internet or other sources and renders it onto a virtual display in its memory. Accordingly, the present invention provides for novel anticancer strategies. The media settings specify proportions of a first set and a second set of media content items. Additionally, together with such foulant collectors, a fluorocarbon polymer may be used as a surface of a vessel or conduit in the PFT process, for reducing fouling.
