Significance of hydrated radius and hydration shells on ionic permeability during nanofiltration in dead end and cross flow modes
Berrin Tansel,John C. Sager,Tony Rector,Jay L. Garland,Richard F. Strayer,Lanfang H. Levine,Michael S. Roberts,Mary E. Hummerick,Jan Bauer +8 more
TL;DR: In this paper, the authors investigate the permeability characteristics of ions present in the aerobic rotational membrane system (ARMS) effluent through a nanofiltration membrane and evaluate the effectiveness of nan-filtration process to remove dissolved solids.

Intercontinental Dispersal of Bacteria and Archaea by Transpacific Winds
David J. Smith,Hilkka Timonen,Daniel A. Jaffe,Dale W. Griffin,Michele N. Birmele,Kevin D. Perry,Peter D. Ward,Michael S. Roberts +7 more
TL;DR: It seems plausible, when coupled with atmospheric modeling and chemical analysis, that microbial biogeography can be used to pinpoint the source of intercontinental dust plumes, and the overall contribution of Asian aerosols to microbial species in North American air warrants additional investigation.

Influence of Elevated CO2 on the Fungal Community in a Coastal Scrub Oak Forest Soil Investigated with Terminal-Restriction Fragment Length Polymorphism Analysis
TL;DR: Sixteen open-top chambers were established in a scrub oak habitat in central Florida where vegetation was removed in a planned burn prior to chamber installation to examine the influence of elevated atmospheric CO(2) on the fungal community in different soil fractions.

Community-level physiological profiling performed with an oxygen-sensitive fluorophore in a microtiter plate.
TL;DR: Community-level physiological profiling based upon fluorometric detection of oxygen consumption was performed on hydroponic rhizosphere and salt marsh litter samples by using substrate levels as low as 50 ppm with incubation times between 5 and 24 h.

Soil microbial community response to nitrogen enrichment in two scrub oak forests
Jennifer Adams Krumins,John Dighton,Dennis M. Gray,Rima B. Franklin,Peter J. Morin,Michael S. Roberts +5 more
TL;DR: The results imply that bacterial communities may be more sensitive than fungi to intense pulses of nitrogen in sandy soils, and that FL consistently supported more bacterial and fungal biomass than NJ.
