| The National Guard's origins trace back to the militia of the first settlements in America. Since its inception in 1636, the National Guard has played a vital role in the nation's defense, from the Revolutionary War to the most recent conflicts in Iraq and Afghanistan. The utility of the National Guard has been questioned since the late 19th century, but political pressure from the states has always been sufficient to ... |

| In 2007 the Spanish shipbuilder Navantia won the contract to rebuild the Australian navy with high-end destroyers and amphibious ships. The same year, the Chilean shipyard ASMAR won the contract to build an advanced Icelandic Coast Guard Vessel. Both shipyards just a few years before had been importing design and construction technologies from abroad; now in a rapid evolution of capability, they had become net technology exporters. A similar process ... |

| Owning and operating airports is an expensive business. For many local governments and private corporations involved in this endeavor, the business of airport management can be extremely lucrative when the facility and the operation are effectively and efficiently administered. For the Department of Defense (DoD), airport management is a huge expense. During this time of historic budget reductions, one wonders whether the existing portfolio of military airfields can be sustained. ... |

| The question of how environmental variability affects populations of marine top predators is an important one because of their role within ecosystems and their potential to influence community structure and biodiversity. An understanding of the patterns of distribution and abundance and particularly the causes of that variation is critical to making informed assessments of the importance of anthropogenic activities to marine mammal populations. This project will quantify changes in distribution, ... |

| Napoleon's invasion of the Iberian Peninsula brought Spain, Portugal, and Britain into a close, if sometimes uneasy alliance. When an expeditionary force led by General Sir Arthur Wellesley, later the 1st Duke of Wellington, disembarked in Portugal in August 1808, the British Army had been at war with France for five years. If the experience gained during campaigns on five continents had sharpened the efficiency of the Commissary Department, whose ... |

| In this work we report a systematic study of the electron and hole mobilities of GaN(x)As(1-x) alloys with different dopants (Zn, Te) and carrier concentrations (10(17) - 10(19) cm(-3). We found a very slight reduction of the hole mobility in P-GaN(x)As(1-x) compared to p-GaAs, indicating that for small N contents (approx. 1.6%) the valence band is not affected by the N incorporation. In a striking contrast, incorporation of even small ... |

| The British effort in the Southern Campaign (1780-1782) of the Revolutionary War failed because of flawed national strategy and a failure to focus sufficient elements of national power against a background of competing global threats. In the American colonies, military power in isolation was ineffectively substituted for diplomatic, political, and economic effort. The operations in the Carolinas took place because no other strategic options were available given the basic and ... |
