In this study methods were developed for the prediction of wave
conditions that are hazardous to navigation at river entrances, with
emphasis on applicability to the Columbia River. There are two basic
components to the prediction system: (1) a semi-automated spectral
method for forecasting the significant height and average period...
This compilation follows the Fifty-Seven-Year Index to the Sierra Club Bulletin annuals, 1893-1949, compiled by Dorothy H. Bradley and George Shochat and published by the Club in 1952. This index covers the monthly issues from 1950 through 1976 as well as the annuals, which were dated as monthly issues but...
Ant-300, a psychrophilic marine vibrio, was starved for periods in excess of one year. Cells starved at a high initial cell density increased in numbers from 100 to 800% of the initial number of cells during the first week. Fifty percent of the population remained viable for six weeks while...
By using continued fractions the set of positive
irrationals can be put in one to one correspondence
with the set of sequences of positive integers. The
entries of an arbitrary sequence of integers can be any
subset of Z and each integer appearing can occur once,
infinitly often, or anything...
In the summers of 1973, 1974 and 1975, I investigated population
age structure and density, and behaviors relating to habitat
selection, predator avoidance and intraspecific interaction in a population
of northwestern salamanders in a lake in the Oregon Cascade
Mountains. The study was carried out by skin- and scuba-diving at...
Under defined cultural conditions, zygotes of the brown alga
Fucus distichus L. Powell divide synchronously to form two-celled
embryos at approximately 24 hours after fertilization. These two
cells differ from one another in gross morphology, ultrastructure,
cytochemistry, and developmental fate. Cytochemical staining and
autoradiography indicated that a sulfated polysaccharide was...
With over 800 languages spoken on the continent of
Africa, inter-cultural communication has always been difficult.
In addition, many of the peoples of Africa have
experienced colonial oppression. Various powers have
sought to interfere with intra-cultural dialogues and the
free flow of information. Their effectiveness, however,
was limited because of...
Oregon Biography Index is intended to serve primarily as a starting point in locating biographies of Oregonians. We have indexed 47 historical volumes which are either entirely devoted to biographies or have large self-contained biographical sections. The profiles in the books vary widely in accuracy and detail. Birth dates of...
