Infections on Cruise Ships

Microbiology Spectrum, 2015
ABSTRACT The modern cruise ship is a small city on the seas, with populations as large as 5,000 seen on large ships. The growth of the cruise ship industry has continued in the twenty-first century, and it was estimated that nearly 21.3 million passengers traveled on cruise ships in 2013, with the majority of these sailing from North America.

Corrected Method for Scaling the Structural Response Subjected to Blast Load

Journal of Marine Science and Engineering
In scale-down tests of ship structures subjected to a blast load, the accuracy of the predicted response of a prototype is affected by the material substitution and geometric distortion between a scaled model and a full-size structure; this is known as ...
