The tragic events of 9/11 and the concerns about the potential for a terrorist or hostile state attack with weapons of mass destruction have led to an increased emphasis on risk analysis for homeland security. Uncertain hazards (natural and engineering) have been successfully analyzed using probabilistic risk analysis (PRA). Unlike uncertain hazards, terrorists and hostile states are intelligen...

NATO’s strategic transformation will have an important impact on the Alliance’s approach to the Mediterranean and on the future of its Mediterranean Initiative. During the Cold War, NATO’s strategy, doctrine, and military capabilities were oriented toward deterring a military threat from the Soviet Union. Today, the threats and challenges are more diverse—and more indirect. They range from ethn...

natural gas is often associated with nitrogen and heavy compounds. the heavy components in the natural gas not only can feed downstream units, owing to the low temperature process may be formed solid as well. therefore, heavy components separation can be a necessity and produce useful products. virtually, all natural gases are containing nitrogen ​​that would lower the heating value of natural ...

Next year's Quadrennial Defense Review (or QDR) will be the most important since the end of the Cold War. A frank appraisal of the nation's strategic future in light of September 11, 2001 (9/11), experience in the war on terrorism, and ongoing conflicts in Iraq and Afghanistan indicates a need for substantial adjustment to the strategy reflected in QDR '01. Such adjustments in defense strategy ...

of turbulence models for shear ows by a double expansion technique," Phys. Fluids \Conservation laws and two ux spectra of hydro-dynamic convective turbulence," Physica D 57 (1992). 15 Bolgiano and Kolmogorov scaling are believed to occur together in general ows; this suggests that the general dissipation rate model could combine the results for both scalings as in Eq. (40). 2 However, a comple...
