Druids and Mound-Dwellers

Artificial Intelligence and Rubble-Mound Breakwater Stability

Breakwaters are coastal structures constructed to shelter a harbour basin from waves. There are two main types: rubble-mound breakwaters, consisting of various layers of stones or concrete pieces of different sizes (weights), making up a porous mound; and vertical breakwaters, impermeable and monolythic, habitually composed of concrete caissons. This article deals with rubble-mound breakwaters....

DRUIDS--detection of regions with unexpected internal deviation from stationarity.

Most methods for inferring phylogenies from sequence data assume that patterns of substitution have been stationary over time. Changes in evolutionary constraint can result in nonstationary substitution patterns that are phylogenetically misleading unless modeled appropriately. Here we present a multiple-alignment-based method to identify regions that are likely to contain misleading phylogenet...

Tuberculin Sensitivity in Town and Country Dwellers

METHOD OF TESTING. For all, except a few who are specially mentioned, this was the Mantoux test. Owing to the impossibility of recalling all the clinic attenders for a second test, the Mantoux test using .01 mgm. of Old Tuberculin (O.T., 0.1 ml. in 1/10,000 dilution) had to be accepted in these. All others were tested with 1 mgm. O.T. (0.1 ml. in 1/100 dilution). Tuberculin jelly (3 per cent. O...

Structure of a Carbonate/hydrate Mound

A one-kilometer-diameter carbonate/hydrate mound in Mississippi Canyon Block 118 has been chosen to be the site of a multi-sensor, multi-discipline sea-floor observatory. Several surveys have been carried out in preparation for installing the observatory. The resulting data set permits discussing the mound’s structure in some detail. Samples from the water column and intact hydrate outcrops sho...
