This study presents a mooring analysis of the Ocean Sentinel buoy, which is a mobile test platform for Wave Energy Converters. The Ocean Sentinel is owned and operated by the Northwest National Marine Renewable Energy Center (NNMREC) at Oregon State University (OSU). The study involved a field observation as well...
Acoustic scattering layers of biological origin have been observed for nearly 70 years across the world’s oceans. The organisms that comprise these layers are known to be important features in most oceanic ecosystems, providing a vital trophic link between small phytoplankton grazers and larger species. There are many aspects of...
Light plays an important role in ecological processes in the ocean both day and night. While relatively inexpensive, off the shelf instruments are available to measure Photosynthetically Active Radiation or PAR during the day, efforts to quantify light levels at night have proven more difficult. The goal of this work...
Small pelagic fish represent a critical trophic link between plankton and large predators in marine upwelling ecosystems such as the California Current System. Populations of these fish are highly variable over time and are characterized by extreme fluctuations in abundance, which have significant ecosystem impacts. The causes driving
this instability...
Juvenile walleye pollock (Theragra chalcogramma) are one of the primary prey items for bird and mammal predators in the Bering Sea and support a large commercial fishery. An understanding of the environmental factors that determine the horizontal and vertical distribution of juvenile pollock is needed to estimate the effects that...
Developmental research has suggested that parenting practices may impact the
development of risk behaviors later in life. However, little evidence exists regarding
how parenting may impact actual decision processes that precede poor choices. This
study examined how parenting practices in early childhood influence the development
of decision-making competence (DMC), a...
Boiling dynamics and related heat transfer mechanisms have been widely studied for several decades. During that time, incredible progress has been made on quantifying bubble departure phenomena including growth rate, departure frequency, associated natural and forced convection, and radiation additions to the overall heat transfer rate. With this, the thermal...
Breakthroughs in heat sink design are now limited by conventional manufacturing techniques which can only produce basic fin shapes with homogenous surface structuring. Additive Manufacturing (AM) is a potential disruptive technology for heat sink design and other convective heat transfer solutions, as surface properties can be directionally varied to maximize...
The Confucius Institutes program is a Chinese organization established in 2004 to provide the world with language instruction and increase cultural awareness. The program forms joint venture business models with universities and schools around the world to establish language and culture centers on their school’s campus (“Constitution and By-Laws”). Over...
Impact of reproductive processes upon female health has yielded conflicting results; particularly in relation to the role of
reproduction-associated stress. We used the viviparous tsetse fly to determine if lactation, birth and involution lead to
damage from oxidative stress (OS) that impairs subsequent reproductive cycles. Tsetse females carry an intrauterine...
