Temporal variations in individual spectrum lines
emitted by a microwave discharge in pure helium are
investigated: The discharge is produced in a quartz tube
located inside of a section of waveguide which carries
pulsed 3 centimeter microwaves. The helium used is purified by a three-fold process consisting of treatment with...
Effective two-body interactions were obtained from
realistic nucleon-nucleon potentials and applications made
in calculations of ground state properties of even-even N=Z light nuclei. The admixture of high momentum states into
the nuclear wavefunction caused by the strong, short-range
repulsion of the two-nucleon force was taken into account
by making a...
It is important to avoid misallocation of resources for either
private or public production. Misallocation in public programs
can result from failure to employ resources in h:igh priority uses
or to eliminate programs that have become obsolete. This study
evaluates the benefits and costs of the continuing public program
aimed...
Capture fisheries can potentially provide a wide range of social benefits, many of which make important contributions to local livelihoods and national economies. However, in practice, and in many representations of fisheries, the starting point for assessment is the biological, fish, element of the system and its production potential. The benefits...
There has been a long-standing interest in local knowledge in fisheries research and management. Much of this interest has been in terms of how local knowledge can be interpreted scientifically and used by fisheries experts and managers. Local knowledge becomes the property of scientists, wrapped up in a format and...
We examine the 0–100 Ma paleoceanographic record retained in pelagic clay from the South Pacific Gyre (SPG) by analyzing 47 major, trace, and rare earth elements in bulk sediment in 206 samples from seven sites drilled during Integrated Ocean Drilling Program Expedition 329. We use multivariate statistical analyses (Q-mode factor analysis...
Dating pelagic clay can be a challenge due to its slow sedimentation rate, post-depositional alteration, and lack of biogenic deposition. Co-based dating techniques have the potential to create age models in pelagic clay under the assumption that the flux of non-detrital Co to the seafloor is spatially and temporally constant,...
