history of Rosa González Gómez, a Mexican woman who spends part of
each year in the United States and part in Mexico. Comparing the
story of Rosa's life, as told in her own words, with literature in the
social...
A study of the distribution, relative abundance and diet of
fishes sympatric with juvenile sockeye salmon, Oncorhynchus nerka
(Walbaum), within the freshwater nursery areas of the Naknek River
system was undertaken from 1961 to 1963. The study was part of an
extensive investigation to determine what factors in the freshwater...
The Purpose of the Study
The primary purpose of this study was to assist in the structuring
of an empirically based vocational teacher preparatory program by determining
the hierarchical levels of common professional education competencies
needed by community college and secondary school vocational
instructors. Several dimensions were considered: personal administration...
A group of trout that reside in streams of the desiccating lake
basins of southeastern Oregon differ markedly from other known
Salmo. Known commonly as the red-band trout, this fish was subjected
to chromosome analysis for comparison with other species of
western North American Salmo. The karyotype of the red-banded...
Understory species associations and their association with tree species were examined on three intensively studied stands. We studied the chronosequence of understory species associated with different aged singleleaf pinyon (Pinus monophylla Torr. and Frem.) trees. Mid- to late pinyon-juniper understory succession was found to be more spatial than floristic in...
Moisture damage has long been recognized as one of the most
critical factors influencing the performance of asphalt concrete (AC)
pavements. This moistureinduced damage occurs from either the
physical separation of the asphalt film from the aggregate or the
softening of the asphalt binder within the AC mixture in the...
Phytoplankton dynamics in Auke Bay, Alaska, were studied during
summer, 1969. Nitrate, chlorophyll a, particulate organic carbon,
phytoplankton and zooplankton species composition and hydrographic
and meteorological data were collected and analyzed.
Nitrate input into Auke Bay through freshwater runoff was negligible.
A bloom of Thalassiosira aestivalis formed the spring bloom...
