In the face of environmental stressors, change is imperative for species to remain in place. The nature and degree of this change is of great interest, as it sheds light into the ways in which species respond to ecological and habitat change and may continue to respond during periods of...
In 19589 J. J. Lingane published an article describing the behavior of an electrolysis using controlled potential coulometry. A typical titration was an hour or more, limiting the variety of applications of the technique. Stephens, Jakob, Rigdon and Harrar looked into the many procedures that have been proposed to locate...
Practical bipedal robots need to be simultaneously efficient, robust, and versatile machines, but designing robots dynamically capable of these demands has been a significant bottleneck. We designed ATRIAS to be a highly dynamic biped capable of both walking and running untethered in real environments. To meet these goals, ATRIAS is...
The fission Time Projection Chamber (fissionTPC) is a compact (15 cm diameter) two-chamber
MICROMEGAS TPC designed to make precision cross-section measurements of neutron-induced fission.
The actinide targets are placed on the central cathode and irradiated with a neutron beam that passes
axially through the TPC inducing fission in the target....
In the Santa Clara Avenue oil field, the nonmarine
Sespe Formation of Oligocene age has produced 4 million
barrels of oil trapped by a Miocene mafic igneous
intrusion that cuts across bedding. Throughout most of
the oil field, the Miocene and older beds dip about 15°
northwest. The intrusion may...
A majority of states require parental consent or notification before a minor may have an abortion. Parental involvement laws are based in part on the assumption that abortion poses a risk to the psychological health of adolescents. Previous research has catalogued the risks to adolescent mothers and their children posed...
Vertisols and other vertic-intergrade soils are found all over the globe, including many agricultural and urban areas. These soils are characterized by their cyclical shrinking and swelling behaviors, where bulk density and porosity distribution both vary as functions of time and/or soil moisture. In turn, alterations in physical soil parameters...
The use of native plants in restoration and afforestation has increased worldwide as their benefits to habitat quality, ecosystem services and local community well-being become widely known. In many restoration and afforestation sites, the most cost-effective and efficient way to establish plants is to use seedlings. Unfortunately, there is a...
Northern anchovy (Engraulis mordax) are a dominant forage fish in the California Current large marine ecosystem (CCLME). However, little is known about northern anchovy abundance, distribution, age structure, or population fluctuations relative to ocean conditions in the eastern boundary upwelling system off the U.S. West Coast. This thesis includes three...
