Estimates of the relative motion between the Hawaiian and Louisville hot spots have consequences
for understanding the role and character of deep Pacific-mantle return flow. The relative motion between
these primary hot spots can be inferred by comparing the age records for their seamount trails. We report
⁴⁰Ar/³⁹Ar ages for...

High-pressure torsion (HPT) is an effective severe plastic deformation (SPD)
technique to produce bulk nanostructured materials (BNMs). These BNMs often show a combination of exceptional mechanical and physical properties. Processing of single metals and alloys by HPT has been understood that the homogenous microstructures can be achieved throughout the disk...
This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...
Bransfield Basin is an actively extending marginal basin separating the inactive South Shetland arc from the northern Antarctic Peninsula. Rift-related volcanism is widespread throughout the central Bransfield Basin, but the wider eastern Bransfield Basin was previously unsampled. Lavas recovered from the eastern subbasin form three distinct groups: (1) Bransfield Group...
Amyotrophic lateral sclerosis (ALS) is a devastating neurological disorder characterized by neuromuscular junction decay, motor neuron death, progressive paralysis, and eventually death of the individual, usually by respiratory failure. Oxidative stress is a prominent hallmark of the disease and is often accompanied and exacerbated by mitochondrial dysfunction and neuroinflammation. This...
"A pilot study conducted for the Environmental Protection Agency." "Based on field work conducted during the months of July and August 1976, the following report describes the characteristics of vegetation at the upper limit of intertidal wetland in five Oregon coastal marshes and relates vegetation characteristics to marsh zonation, elevations...
