 | The United States Air Force is committed to purchase the most capable and efficient tanker available to replace its aging KC-135 fleet. One capability demanded of the new tanker is the ability to receive fuel from other tankers while airborne, a practice referred to as fuel consolidation. Under the operating constraint of reduced budgets and continuing pressure to reduce Air Mobility Command's overall fuel costs, it is likely that future ... |

| Simulations of station keeping and burial of a dead weight anchor device were performed using the Vortex Lattice Mine Burial/Migration Model (VORTEX). The VORTEX model was developed at Scripps Institution of Oceanography under previous ONR funding, (Inman and Jenkins, 2002; Jenkins and Inman 2002, Jenkins and Wasyl 2006). This model has been validated in field experiments conducted under ONR's Mine Burial Program. |

| In 2006, five field tests were made at Stennis Space Center of a Sediment Layer Electrode Deployer (SLED). The objective was to submerge an array of vertical-plate electrodes, with a total surface area of 18,580 cm squared into anoxic sediment layers by a method that may be accomplished from research vessels. The embedded electrodes would allow power generation from the Benthic Unattended Generator (BUG) technique. Towed-deployment and vibration-deployment techniques were ... |

| We study the scaling properties of heterogeneities in nematic (liquid crystal) polymers that are generated by pressure-driven, capillary Poiseuille flow. These studies complement our earlier drag-driven structure simulations and analyses. We use the mesoscopic Doi-Marrucci-Greco model, which incorporates excluded-volume interactions of the rod-like particle ensemble, distortional elasticity of the dispersion, and hydrodynamic feedback through orientation dependent viscoelastic stresses. The geometry likewise introduces anchoring conditions on the nano-rods which touch the ... |

| Bacteria from diverse habitats in the marine environment adhere to inert surfaces through extracellular polysaccharides following initial contact with the substratum. Although proteins may also participate in the initial adhesion process, polysaccharides are the most obvious structures anchoring bacterial cells to surfaces after the initial contact event. A biofilm-forming marine bacterium, Hyphomonas strain VP-6, produces two separate adhesive surface polysaccharides; a temporally synthesized, polar, neutral or positively-charged holdfast molecule, and ... |

| In coastal systems, patches of seagrass are frequently destroyed by propeller scarring and anchor damage near waterways, resulting in denuded 'blowouts'. Persistence of blowouts is a poorly understood phenomenon, and I proposed that (1) benthic 'drift' algae (marine analogs of terrestrial tumbleweeds) settle in blowouts and protract recovery of seagrass by shading the affected patches, and (2) that algal masses may be more easily trapped in small blowouts than in ... |
