We present new observational data on small-angle light scattering properties of natural, random shaped particles, as contrasted with spherical particles. The interest in
this "shape effect" on scattering arises from the need for a suitable kernel matrix for use in the laser diffraction method (LD) of particle sizing. LD is...
Studies were conducted to establish some characters which
could be used, either in the field or in the laboratory, to differentiate
between annual ryegrass (Oregon), Lolium multiflorum Lam. , and
Linn perennial ryegrass, Lolium perenne L.
Vernation, percentage of glumes covering the spikelets, and
height of seedlings seem to be...
In the summer of 1931, the author investigated Tillamook, Netarts, and Alsea bays to determine their suitability for oyster culture. He also investigated the state of oyster growing in Yaquina Bay, the only place in the state where oysters were grown commercially. This is an unpublished manuscript that was distributed...
This paper describes a method for measuring nearshore ocean wave characteristics with a land-based, long-period vertical seismometer. The wavemeter system has proven to be highly reliable and produces continuous wave observations at low cost. It is now operational at six Coast Guard stations along the Oregon and Washington coasts; data...
The paper analyses the annual accounts for the period 1990-94 of a sample of approximately 100 fishing firms operating out of ports in Schleywig-Holstein and exploiting finfish stocks in the North Sea and Baltic, and shrimp stocks in the North Sea. Detailed information is provided on costs and returns by...
