Bacteria were isolated from water at Alder Slough, Oregon. Of
15 isolates grown successfully in the medium employed, 100% showed
measurable uptake of Zn-65. A growth curve was established for one
isolate, a gram-negative rod designated AS-1. Increasing Zn-65 uptake
was found generally to correspond with increasing growth of
AS-1....
The seabed is envisaged to meet the increased future demands for
minerals from the rapidly growing industrialized societies of the world.
Shipboard analysis of cores can significantly reduce the cost and time
spent at the exploratory drilling stage by obviating the need to go back
to land for analysis. It...
The stability analysis for a heated tube system is an
important safety feature of a nuclear power plant.
Although the system theory is well established for linear
systems described by ordinary differential equations, there
is still a shortage of theory dealing with a distributed
system, which is described by partial...
The utilization of ⁷⁷ [superscript m] Se, half life 17.5 s, and ⁷⁵ Se, half life 119.8 d, for quantification of trace amounts of Se in well water and biological materials by means of instrumental neutron activation analysis (INAA) is described. A Se detection limit of 0.03 ppm was achieved...
The goals of this study were to discover and compare the religious
and philosophical traditions which have shaped Japanese and American
cultures, and to make a case for interdisciplinary transcultural programs
of study in higher education. Specifically, the purposes of this
study were to: (1) describe and trace historically the...
The purpose of this study was to determine if differences exist among NCAA
divisions I, II and III as well as between Athletic Directors and Primary Women Administrators
with regard to the perceived competencies and preparatory coursework required
of athletic administrators.
A mail survey utilizing a six point forced choice...
Bar-pool morphology in rivers can provide vital habitat to aquatic species, notably salmonids, which require gravel riffles to bury eggs and pools for hydraulic and cold-water refuge. In some cases, the erosion and subsequent deposition of coarse sediment downstream of a dam removal can modify habitat by inundating bar-pool structure,...
An integrated sampling and gamma ray spectrometry system has
been developed for analysis of TRIGA reactor primary cooling water.
A microcomputer controls pumps and valves using BASIC and assembly
language programs to pump 300 ml liquid samples into a reference
geometry surrounding a Ge(Li) detector. Gamma ray spectra are
acquired...
Thirteen New World populations of Megachile rotundata and M. apicalis and
two Old World populations of M. rotundata were analyzed at 23 enzyme loci using
cellulose acetate electrophoresis. Conventional and G- or C-banded karyotypes were
also examined in these populations. The principal findings are (1) No differences
were found in...
A personal computer with a Data Acquisition and
Control Adapter interface has been used to monitor the
power of the Oregon State University TRIGA Reactor, and
from the time behavior of the reactor power the reactivity
has been computed using the point kinetics equations and
displayed on a digital read-out...
