Over-winter growth of juvenile salmonids may be linked to ocean survival and thus species persistence. Diet, growth, and prey available to juvenile coho, Oncorhynchus kisutch, were examined from December 2004 to April 2005 in four tributaries of the West Fork Smith River (WFSR), Oregon. Juvenile coho growth rate and condition...
Female participation in high-contact sports has increased
dramatically in the past two decades, raising concern regarding injury to
the female breast and the need for protective equipment. While the use of
chest/breast protectors by women is advocated, little is known of their
efficacy and effect on athletic performance. The purpose...
The vascular endothelium is a single cell layer that lines the lumen of the entire vasculature. It is the site of synthesis of nitric oxide (NO), a vasodilatory compound synthesized by endothelial nitric oxide synthase (eNOS). NO causes intracellular calcium sequestration of the vascular smooth muscle cells, relaxing and dilating...
The purpose of this study was to determine kinetic and kinematic
characteristics of Thai Boxing Roundhouse Kicks. In order to measure the kinetic
variables of peak force and impulse, a triaxial accelerometer was inserted into a
kicking bag. The force data were derived from the known mass and measured
acceleration...
Combustion emissions produced from burning real transportation fuels have many environmental impacts. However, detailed chemistry across multiple phases, time scales, and thermodynamic conditions make predicting combustion emissions challenging. Detailed modeling of the gas phase alone is prohibitively expensive, due to the large size and stiffness of the kinetic models. The...
A distinguishing feature of elite cross-country (xc) skiers is their superlative upper body power (UBP). Race points/rankings are highly correlated to UBP, thus it appears that UIBP training is an integral component to the success of xc ski racers. Recently, roller board training was shown to be superior for improving...
Great blue heron (Ardea herodias) eggs and prey items were collected from six colonies on the Columbia and Willamette rivers and Puget Sound during 1994-95. Contaminant concentrations, reproductive success, and biomagnification factors (BMFs) were determined and effects of residue levels were measured by H4IIE rat hepatoma and ethoxyresorufin-O-dealkylase (EROD) bioassays....
Over the past few decades, a primary focus has been on the negative health effects of not participating in regular moderate-to-vigorous physical activity (MPVA). Only recently has sedentary behavior been studied as a distinct and independent risk factor for adverse health outcomes. This dissertation sought to provide new insights into...
This study surveyed a sample population of manufacturing companies in Oregon. Respondents were surveyed concerning their perceptions of ergonomics and their use of ergonomic consulting services from three potential sources of ergonomic consulting services. The sources of ergonomic consulting services were the Oregon Occupational Safety and Health Administration (OR-OSHA), Workers'...
Purpose: The purpose of this investigation was to identify a deep-water running (DWR) style that most closely approximates terrestrial running. Methods: Twenty healthy male and female intercollegiate (NCAA III) distance runners were videotaped from the right sagittal view while running on a treadmill (TR) and in deep water at 55-60%...
