BACKGROUND Infectious gastrointestinal illness (IGI) outbreaks have been reported in U.S. Navy ships and could potentially have an adverse mission impact. Studies to date have been anecdotal. METHODS We conducted a retrospective analysis of weekly reported disease and non-battle injury health data collected in 2000-2001 from 44 U.S. Navy ships while sailing in the 5th Fleet (Persian Gulf and ...

Following a brief reviev of prior work on wave resistance of bodies of revolution carried out by Havelock and Weinblum a discussion is presented of the approximate relations between the shape of sectional-area curves and of hydrodynamic irregularity distributions. The latter are expressed by polynomials, which lend themI selves to an evaluation of the basic resistance integrals by computing int...

The invention as disclosed is a system for real time detection of tsunami waves. A tsunami is considered a "shallow water wave"; having a large wavelength compared to the ocean depth. A tsunami can have wavelengths ranging from 100 to 500 km, and amplitudes up to 60 cm (i.e., a pressure signal of up to 1 psi). At least one telecommunications grade optical fiber cable fitted with repeaters spann...
