Contaminants in stormwater such as heavy metals, PFASs, PCBs, and PAHs are an issue for public infrastructure and remediation practices. Biochar, granular activated carbon (GAC), OGSIR soil, and commercial adsorbent materials have been evaluated with the heavy metals Cu2+ and Zn2+. Copper and zinc as stormwater contaminants were treated with...
Otoferlin is a C2-domain, transmembrane protein whose mutated form is responsible for the DFNB9 subtype of prelingual hearing impairment. Mutations in otoferlin cause an autosomal recessive, non-syndromic form of deafness that is characterized by auditory neuropathy/ auditory dissynchrony (AN/AD), meaning that the outer hair cells (OHCs) are normal, and the...
The genetic aspects of population health are critical, but frequently difficult to assess. Of concern has been the genetic constitution of Scandinavian wolves (Canis lupus), which represent an important case in conservation. We examined the incidence of different congenital anomalies for 171 Scandinavian wolves, including the immigrant founder female, born...
National Forest management in the Pacific Northwest is shifting
from a focus on commodity production to ecosystem management, in which
the health of the entire forest ecosystem is considered, rather than that
of a few key species. Ecosystem management includes retention of some
live trees following timber harvest (green-tree retention)...
Despite more than two centuries of exploration, including more than six million deep wellbores with depths exceeding 40,000 feet in some parts of the world, our ability to constrain subsurface processes and properties remains limited. Characteristics of the subsurface vary and can be analyzed on a variety of spatial scales....
Falls are a common problem among older adults, including those who are relatively healthy and living independently. Exercise has been recommended as an intervention to reduce falls by slowing and/or reversing age-related declines in balance, strength, and mobility. However, it remains unclear which types or combinations of programs are most...

For coaches to qualitatively analyze the performance of sport skills as executed by their
students, they must possess an internal image of the desired skill against which to make
comparisons (Hoffman, 1983; Pinheiro & Simon, 1992). Leas and Chi (1993) have
indicated that there are differences between novice and expert...
To study the combined effects of seedling quality and fertilization at the time of planting, three experiments were established in western Oregon during the winter of 2000. The first experiment investigated the effect of preplanting rootvolume and fertilization rate on the field performance of 1+1 Douglas-fir seedlings during two growing...
Coastal Douglas-fir (Psuedotsuga menziesii (Mirb.) Franco) 1 + 1 seedlings were fertilized with two types of fertilizers (NB4NO3+K2SO4 and (NH.4)2 SO4+KC1) at four rates (0, 80, 160, 320 kg N and K/ha) split over 3 application dates (September 19, October 13, November 1, 1996). By January 10, total Kjeldahl nitrogen...
