Residual osteochondral debris represents a clinical problem associated
with arthroscopic debridement and curettage of joint surfaces. At the Oregon
State University Veterinary Teaching Hospital (OSU-VTH), during a period
from January, 1983 to August, 1986, incidence of radiographically recognizable
osteochondral debris in the carpal joints of postarthroscopic equine patients was
excessive....
This research examined the potential for using peanut husk as a fiber alternative to wood in the production of melamine-formaldehyde (MF) particleboard. MF resin was used to produce panels with one, three, six, nine or 12 percent resin contents. Modulus of Rupture (MOR), Modulus of Elasticity (MOE), Internal Bond (IB)...
We hypothesized that calpain activity is elevated in response to muscle damage. To test this hypothesis, we examined the degradation of α-fodrin into its 150 and 145 kDa fragments following either 20 eccentric or isometric contractions. In addition, experiments were performed in the presence or absence of E-64-d, a calpain...
Small manufacturing firms often serve a domestic market but would like to expand their sales overseas. It is difficult for a small firm to develop overseas contracts and relationships, however, in part because of their small size, and because the advantages of their products may not always be obvious. The...
The age, or residence time of water is a fundamental descriptor of catchment hydrology, revealing information about the storage, flow pathways and source of water in a single integrated measure. While there has been tremendous recent interest in residence time to characterize catchments, there are few studies that quantify residence...
This dissertation re-examines the now standard perceptual model of hillslope
hydrological response to rainfall, which includes the growth of a saturated wedge at the soil-bedrock interface or impeding layer. It also challenges the notion of bedrock impermeability and the assumption that the pattern of subsurface stormflow is determined by the...

This dissertation re-examines the now standard perceptual model of
Moisture intrusion in residential structures can lead to substantial fungal decay and this damage costs billions in repair/replacement costs. The extent of damage and the rate at which it occurs are primarily dependent on the wood moisture content and temperature in the structure. Determining the risk of decay for various...
The goals of this research were to a) characterize the protein-function relationships of skeletal muscle single fibers from the mouse hindlimb b) examine mouse-strain related differences in myosin heavy chain composition (MHC) and single fiber contractile function, and c) quantify changes in fiber size and contractile function in response to...
Studies of physiological effects of fungicides on fungi are critical for understanding
modes of action and mechanism of resistance; however, studies are difficult to perform
on filamentous fungi because of the inability to produce homogeneous a biological
system using a mass of mycelium. Moreover, the presence of rigid cell wall...
