 | Asymmetric threats pose increasing challenges to combatant commanders in Stability, Security, Transition, and Reconstruction (SSTR) Operations. Threats once confined to littoral waters now extend out to the green water theater. Many NATO countries operate their post Falkland war built frigates in these missions, in which lightly armed small, agile and fast craft are often encountered. This study uses freely available real-world data to build a simulation using an agent-based modeling ... |

Renee Johnson; LIBRARY OF CONGRESS WASHINGTON DC CONGRESSIONAL RESEARCH SERVICE
|
 | In 2006, commercial migratory beekeepers along the East Coast of the United States began reporting sharp declines in their honey bee colonies. Because of the severity and unusual circumstances of these colony declines, scientists have named this phenomenon Colony Collapse Disorder (CCD). Current reports indicate that beekeepers in 35 states have been affected. Recent surveys indicate that about one-half of surveyed beekeepers have experienced "abnormal" or "severe" colony losses.

Mitchel B. Berger; Mark A. Lemmon; PENNSYLVANIA UNIV PHILADELPHIA SCHOOL OF MEDICINE
|
| Signaling by the four members of the erbB family of receptor tyrosine kinases involves their ligand-induced homo- and/or hetero-oligomerization. Ligand-induced receptor homodimerization appears to be driven straightforwardly by receptor extracellular domains, and can be recapitulated in vitro. By contrast, hetero-oligomerization cannot be detected in studies of isolated extracellular domains, and has only been observed for receptors in cellular membranes. We were therefore interested in determining which domains of an erbB ... |

The all-too-familiar Russian problem of lack of field sanitation was again apparent as 95% of the infectious disease among the Russian combatants was passed through fecal-oral transmission. A modest 3.7% of infectious disease was passed through airborne transmission and the other 1.3% were other modes of infection. Over half ... |

| Many workplaces contain spaces that are considered to be confined because their configurations hinder the activities of any employees who must enter into, work in, and exit from them. In many instances, employees who work in confined spaces also face increased risk of exposure to serious physical injury from hazards such as entrapment, engulfment, and hazardous atmospheric conditions. Confinement itself may pose entrapment hazards, and work in confined spaces may ... |

| The effect of 2 mg and 4 mg injections of atropine sulfate on helicopter pilots was investigated using a specially instrumented UH-1H helicopter and several laboratory tests. A counterbalanced, within-subjects design was employed in which flight performance, vision, electroencephalographic activity, cognitive skill, and tracking performance were assessed on each of three different drug administration days (placebo, 2 mg, and 4 mg) separated by control days. Results indicated numerous atropine-related difficulties, ... |

| Traditional methods of estimating hazards of toxic stressors in aquatic ecosystems have fail to account for ecologically important interactions within complex systems. A microcosm testing method was developed to assess the effects of chemical stresses (including complex mixtures) on naturally derived freshwater microbial communities. Microbial communities were collected on polyurethane foam artificial substrates and used to establish replicate laboratory ecosystems to be stressed with toxicants. Responses measured included taxonomic richness, ... |
