The effects of mechanical damage, insect infestation and
storage conditions on seed viability of spring wheat were studied by
three known tests, laboratory germination, greenhouse growth, and
tetrazolium staining, so that the relationship of these tests could be
discerned to facilitate seed testing work.
Mechanical damage was induced by threshing,...
The purposes of this investigation were to measure the relative
levels of enzymatic and respiratory metabolism of some vertically
migrating mesopelagic fishes collected from the ocean waters off
Oregon and to modify and adapt an enzyme method for use as a measure
of metabolic activity at sea with a minimum...
The various elements of physical geography are commonly
entertained as factors retarding the mineral industries of Alaska. It
has been shown by numerous writers that the mineral industries of
Alaska are, indeed, in a difficult situation. Only the petroleum industry
and sand and gravel for construction are of much significance...
A criterion is defined to compare seasonal ice coverage in the
Greenland Sea for the years 1900-57, and the areal coverage is
graphed using the 1898-1913 average as a standard. The factors
wielding possible influence on short-term variations of the ice cover
are examined individually and their relative importance established....
Our major effort since initiation of this contract has been directed
toward (1) procuring the gamma-ray spectrometric equipment and integrating
the components into an operational system, and (2) analyzing
the samples obtained from the midwater trawl program of the Department
of Oceanography and evaluating and interpreting the resulting data
Analyses...
Hyperiid amphipods from one-meter plankton net collections made over a two year period at stations 15, 25, 50, and 65 nautical miles off Newport, Oregon, were examined. Nineteen species were identified. The occurrence of some species off Oregon significantly extended
the known geographic ranges. To my knowledge Scina crassicornis burmudensis...
