Oogenesis in the sea urchin Strongylocentrotus purpuratus was
studied at the fine structural level, with special emphasis on the relationship
between the two main cell types within the ovary: the egg cells
and the nutritive phagocytes, or accessory cells. The nutritive
phagocytes are flagellated cells with extensive pseudopods which store...
The metabolism of Strongylocentrotus purpuratus (Stimpson)
was investigated at several levels of urchin organization. Some experiments
were performed with tissues from recently collected
(acclimatized) urchins, Other experiments were performed with tissues
from urchins held at one of two temperatures (acclimated) for
30 days.
Body-component oxygen consumption was measured for bodywall,...
American meteorology was synonymous with subjective weather forecasting in the early twentieth century. Controlled by the Weather Bureau and with no academic programs of its own, the few hundred extant meteorologists had no standing in the scientific community. Until the American Meteorological Society was founded in 1919, meteorologists had no...
The gamma contribution to reactor afterheat
depends on gamma energy since high-energy commas are
more likely to escape from tilt. fuel. The objective of
this work is to investigate the gamma-energy spectrum
of a pure U-235 fission reactor.
Fission-product nuclides are first listed in order'
of importance as contributors to...
This compilation of theses and dissertations (a part of the OSU Bibliographic Series) for the period 1970-1977 reflects this university's emphasis on research and graduate study. It may be viewed as an indicator of the contributions made to the state of Oregon through graduate study and research at Oregon State...
