Abstract:

Methods and apparatuses for depositing agents relatively deep within pores of bio-char. Bio-char is first produced in an airtight oven by heating biomass feedstock. The bio-char is then cooled and steam is diffused into the pores of the bio-char. The steam-laden bio-char is immersed in a liquid bath containing soluble agents that are to be deposited in the pores of the bio-char. The liquid bath cools the char to below the condensation temperature of the steam, whereupon the condensing steam generates a partial vacuum within the pores, drawing the liquid into the pores. The bio-char is then removed from the liquid bath and dried so that the liquid within the pores evaporates, leaving behind the soluble agent. Accordingly, the invention yields bio-char that has soluble agent embedded relatively deep within its pores.

Abstract:

In one embodiment, a transparent relay receives diverted e-mail communications between an e-mail client and an e-mail server. The transparent relay may be configured to examine the e-mail communications for network security policy violations. E-mail communications that do not violate a network security policy may be relayed to their intended destination. Policy actions, such as discarding or redirection, may be performed on those that violate one or more network security policies. The transparent relay may include a pair of communications interfaces running in promiscuous mode, one for downstream communications and another for upstream communications. The transparent relay may decompose a network communication protocol to look network security policy violations.
