This analysis concerns the life and scientific work of Henry
Augustus Rowland (1848-1901), organizer and the first chairman of
the physics department at The Johns Hopkins University in 1876.
Special materials used in this research included three pieces of
Rowland's experimental apparatus which are extant in the Smithsonian
Institution Division...
The presence of the etiologic agent of "salmon poisoning"
disease, Neorickettsia helminthoeca, was demonstrated in eggs of
the trematode vector, Nanophyetus salmincola. Three dogs were
given 100,000 and one dog 82,000 ground fluke eggs by intraperitoneal
injection. The four animals developed "salmon poisoning"
disease and died. One of these dogs...
Of 149 wild animals from two western Oregon river drainage
areas and other localities in which "salmon poisoning" disease (SPD)
is enzootic, including ten mammalian and two avian species, 79
harbored Nanophyetus salmincola, the SPD vector. The shorttail
weasel, Mustela erminea; river otter, Lutra canadensis; spotted
skunk, Spilogale putorius; Norway...

The indicated sum of a real scalar and a real or imaginary
vector is called a scator. Either the scalar part or the vector part
may be null. Scators generalize the complex variable to n-space.
The algebra of scators is not generally associative under multiplication
but the commutative and distributive...
