Correlation of the metabotypes with the microbial profiles derived from culture-independent molecular techniques is increasingly helping to decipher inherent and intimate host-microbe relationships. This integrated, systems biology approach is improving our understanding of the molecular mechanisms underlying multilevel host-microbe interactions, and promises to elucidate the etiologies

of human disorders resulting from unfavorable human-microbial associations, including enteric infections.”
“A wire-cylinder-plate electrode configuration is presented to generate ionic wind with a dc corona discharge in air Selleck STI571 at atmospheric pressure. The objective of the work is to maximize the power supplied to the flow in order to increase acceleration while avoiding breakdown. Thus, the proposed experimental setup addresses the problem of decoupling the mechanism of ion generation from that of ion acceleration. Using a wire-plate configuration as a reference, we have focused on improving the topography of the electric field to (1) separate the ionization and acceleration zones in space, and (2) guide the trajectory of charged particles as parallel to the median axis as possible. In the proposed wire-cylinder-plate setup, a dc corona discharge is generated in the space between a wire and

two cylinders. The ions produced by the corona then drift past the cylinders and into a channel between two plates, where they Doramapimod undergo acceleration. To maximize the ionic wind it is found that the geometric configuration must be as compact as possible and that the voltage applied must be right below breakdown. Experimentally, the optimized wire-plate reference setup provides a maximum flow velocity of 8 m s(-1), a flow rate per unit electrode length of 0.034 m(2) s(-1), and a thrust per unit electrode length of 0.24 N m(-1). The wire-cylinder-plate configuration provides a maximum flow velocity of 10 m s-1, a flow

rate per unit electrode length of 0.041 m(2) s(-1), and a thrust per unit electrode length of 0.35 N m(-1). This 46% increase in thrust is obtained Ricolinostat inhibitor by increasing the electric power per unit electrode length by only 16% (from 175 to 210 W m(-1)), which confirms the gain in efficiency obtained with the decoupled system. In comparison with a simple wire-wire corona configuration, the wire-cylinder-plate configuration increases the ionic wind velocity by up to a factor of 3, and the thrust by an order of magnitude.
