Osteoporotic vertebral fractures are a common and costly public health problem with a high occurrence in older women due to menopausal-onset bone loss. Recent findings suggest that mechanical loading created by upper body resistance training can stimulate bone growth in the lumbar spine, reducing osteoporosis-related bone loss and associated fracture...
Environmental mycobacteria are important opportunistic pathogens for many hosts,
including humans, cattle, and fish. Two well-studied species are Mycobacterium
avium subsp. avium, a significant cause of disseminated bacterial disease in patients
with AIDS, and Mycobacterium avium subsp. paratuberculosis, the cause of Johne’s
disease in cattle. Many other species that are...
Rapid adaptation and evolution based on standing genetic variation and novel mutations is likely to be one of the primary ways that species survive the widespread anthropogenic environmental changes expected of the next century. Three-spined stickleback (Gasterosteus aculeatus) are known to be capable of extremely quick, dramatic adaptation in response...
Marbled Murrelets (Brachyramphus marmoratus) are threatened seabirds that are prone to disturbance both at sea and at old-growth forest nesting areas. I examined murrelet behavior and activity patterns in forest and marine ecosystems of Oregon. Diving behavior was studied during the 1995 and 1996 breeding seasons and was compared to...
A Resource Planning and Management System (RPMS) and Goal
Programming algorithm are integrated into a tool for optimization of
resource allocation in university academic departments. The integrated
approach is then applied to the management models of the
Industrial and General Engineering Department at Oregon State
University and of the Industrial...
Aspects concerning the bionomics of the parasitic honey bee brood mite, Varroa
jacobsoni Oudemans were investigated. Mite mortality is great during the winter season
when the host colony is not rearing brood, appearing to be independent of the mortality of
its host. In winter period, no significant association between the...
This paper corrects an apparent deficiency in the published
information concerning Hardware Description Languages (HDLs) by
introducing and discussing an approach for selecting an HDL for
use in a design project. Although three classes of HDLs are discussed
in this paper, High-Level Languages (HLLs), General Purpose
Simulation Languages (GPSLs) and...
A review of observational coding systems indicated the need for an
instrument which is easy to learn and implement in applied settings,
and which can be applied to diverse populations of disturbed children.
A two phase study was conducted to evaluate the reliability and validity
of observational ratings derived from...
Balance is the ability to establish an equilibrium between the body and its environment. Balance is a key component which is associated with a variety of movements and postural control. Children with cerebral palsy (CP) have difficulties with movement and postural control due to physical and neurological limitations. The purpose...
Pentobarbital binding to hemoglobin, evidence of an interaction
between pentobarbital and 2,3-DPG in binding to hemoglobin, and the
effect of altered oxygen dissociation on the outcome of barbiturate
poisoning were studied.
Ultrafiltration and equilibrium dialysis techniques were used to
determine the binding of pentobarbital to solutions of purified
hemoglobin, diluted...
