The relationship between a parent and child in the first years of life have a significant effect on the development of children. Parenting education can be a valuable resource for learning evidence-based parenting strategies, but access to parenting education is limited in many states. Oregon has a unique statewide system...
The energy harvesting performance of oscillating airfoils is studied using a discrete vortex model (DVM) with a leading-edge separation criterion. The airfoil undergoes a combined sinusoidal heaving and pitching motion at reduced frequencies of k = 0.06 − 0.16, with heaving amplitude of h0 = 0.5c, and pitching amplitude of...
Work-related musculoskeletal disorders (WMSDs) are prevalent among surgeons due to a variety of risk factors. Various subjective tools have been used to investigate the associations between these risk factors and their contributions to the development of WMSDs. This study aimed to provide a summary of a collection of popular subjective...
The effect of a pulse produced by an acoustic or electromagnetic
line source oriented parallel to the edge of a perfectly conducting
half plane is considered. The Green's functions for the modified
Helmholtz equation are found by solving for the Green's functions
for a cylinder of sectorial cross-section, then allowing...
Precision irrigation has made spatially explicit water management a reality. However, detailed knowledge about the spatially variable evapotranspiration is often unavailable. One example location where we can begin to understand the impact of spatial variability on evapotranspiration is at the field edge, which contains a sharp discontinuity in surface conditions....
Five lithologic units, ranging in age from Middle Miocene to Recent,
are defined on the basis of continuous seismic reflection profile records.
Two of the units are Miocene sedimentary and volcanic rocks that have been
truncated to form a major unconformity (post-orogenic surface) related to
the most recent major tectonism...
The pulmonary function scores of 250 male cigarette smokers
were compared with 406 lifetime nonsmokers. A Stead-Wells spirometer
was used to obtain forced vital capacity, forced expiratory
flow, forced mid-expiratory flow, and forced expiratory volume. All
individuals included in the sample were between. the ages of 20 and
49 years....
Remote areas are frequently homes to regional subpopulations of endangered green sea turtles (Chelonia mydas) and their essential habitat. Local communities are often the users and primary stewards of this valuable and charismatic resource. Recognizing this, a Hatohobeian community group in Palau has engaged in longterm monitoring and conservation management...
North Pacific albacore (Thunnus alalunga) is a highly migratory and
commercially valuable species of tuna. All stock assessments and management
decisions for North Pacific albacore are presently based on the assumption of a single,
uniform stock. However, a growing body of evidence from diverse sources suggests
that there are two...
