Genomic instability underlies diseases of unregulated cell growth that result in
cancers and developmental abnormalities in humans. Similar genome destabilizing
mechanisms are used to create genetic variety in crops for use in breeding and trait
development. Errors that occur during DNA replication may cause mutations if
they are not corrected...

Cells are constantly bombarded with mutagens, both endogenous and exogenous in origin. Endogenous sources of mutation include reactive oxygen species formed during aerobic respiration, replication errors by DNA polymerase, and spontaneous deamination and depurination (Jackson 2009). Exogenous sources of mutation include UV and ionizing radiation, aflatoxins, and polycyclic aromatic hydrocarbons...
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%...
Trials to achieve optimal bucking were made with updated OSU-BUCK software in an eastern and a western Oregon location during the summers of 1993 and 1994. The commercial version of the software allows tagging of each log with bar-code identification numbers and therefore provides tracking from stump to customer. Data...
The founders of Cascadia Community College changed faculty role and duties as they designed a new college. The college founders chose which themes of learning reform would be enacted by faculty in this new setting. They determined what elements of traditional roles continued to be important and what new expectations...

Groundwater overdraft in the Wilcox Groundwater Basin, as a consequence of increasing rates of agricultural groundwater withdrawal, has led to significant regional groundwater level decline and threatens to undermine the basin’s long-term water resource security. Updated characterization of the basin’s water resource conditions and agricultural water demand is critically important...
Running economy (RE) is the amount of oxygen utilized (ml.kg⁻¹min⁻¹) when
running a fixed speed, and it has been demonstrated to be an important factor
determining race performance in distance runners. There is evidence that running
economy and/or maximal oxygen consumption (VO₂max) improves over the course
of a training season...
The treatment of certain types of cancers brings with it serious physiological and
psychological side effects in cancer survivors, including: decreased aerobic capacity,
muscle wasting, body composition changes, fatigue, and a diminished overall quality of
life. Exercise may directly influence the physiological side effects of cancer and cancer
treatment, and...
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...
The purpose of this study was to develop a profile
of Christian College physical education faculty members
regarding their academic preparation, professional
experience, and selected duties, as well as to identify
important components of graduate preparation at the
doctoral level for future faculty at these
institutions.
A survey instrument was...
