Abstract: Systems and methods are provided for estimating temporal changes in trace gas fluxes from a modifier of such trace gases. A method can include obtaining measurement amounts of trace gases from measurement sites in a region associated with the modifier. The method also includes computing modeled amounts of the trace gases based on an atmospheric transport model and prior estimates of trace gas flux from the modifier. The method further includes identifying corresponding portions of the measurement amounts and the modeled amounts associated with a time periods during which the spatial differences in measured amounts are predicted to be primarily due to the trace gas flux from the modifier. The method additionally includes selecting as a current estimate of the trace gas flux from the modifier a prior estimate associated with a difference between the corresponding measurement amounts and modeled amounts meet criteria.

Abstract: Present herein is a technique for providing computer and internet access for a group of participants, which can include economically disadvantaged persons. An orientation is first conducted wherein computer technical skills are taught. After the orientation, a computer is provided and installed in the homes of each participant. During installation, the participant is provided with additional training. Internet access is also provided for the participant through a partnership with the local telecommunications provider.

Abstract: Lightweight concrete incorporating expanded polystyrene beads is made by first coating the expanded beads with an aqueous surfactant solution, which preferably contains a substantive cationic surfactant, e.g. a substituted or ethoxylated quaternary ammonium compound containing a C.sub.10 to C.sub.18 alkyl substituent or an ethoxylated primary or secondary amine having a C.sub.10 to C.sub.18 alkyl substituent, and a non-ionic surfactant such as an ethoxylated primary or secondary alcohol or a nonylphenol-ethylene oxide condensate. The wet beads are coated with dry cement and then mixed with a further supply of cement, water and sand or aggregate to complete the concrete mix.
