Objective: To determine the effectiveness of moderate pre-exercise warm-up, static stretching, or a combination of both on muscular force production and hamstring extensibility of the lower extremity. Design and Setting: This experiment was a counterbalanced repeated measures design of four treatment conditions. Subjects participated in warm-up, static stretching, combined warm-up...
The purpose of this study was to characterize glenohumeral joint laxity and
stiffness using instrumented arthrometry. To evaluate the validity of an instrumented
measurement system we compared cutaneous and bone-pinned measures of laxity and
stiffness that replicate previously reported in vivo methodology. Characterization of
capsular laxity was achieved through determination...
The effect of X-irradiation on DNA synthesis in larval salivary
glands of Drosophila hydei was studied using the technique of liquid
scintillation spectrometry and autoradiography. DNA synthesis in
salivary glands of synchronized larvae was measured at successive
stages of third instar development by in vitro uptake of ³H-thymidine
for a...
Benomyl-tolerant Botrytis cinerea was found in snap
bean fields throughout the Willamette Valley while no tolerant
isolates of Whetzelinia sclerotiorum were detected.
Thirty-five benomyl-tolerant isolates of B. cinerea had
slower radial growth rates than eighteen benomyl-sensitive
isolates. Sporulation of an aggressive tolerant isolate
was not stimulated when grown on benomyl-treated...
The semi-parametric approach to the analysis of proportional hazards survival data
is relatively new, having been initiated in 1972 by Sir David Cox, who restricted its use
to hypothesis tests and confidence intervals for fixed effects in a regression setting.
Practitioners have begun to diversify applications of this model, constructing...
Relative use by pronghorns (Antilocapra americana) of 16 range sites was studied during summer and fall of 1971 and 1972 on Hart Mountain National Antelope Refuge, an area of high desert
rangeland in south central Oregon. A Relative Use Index was developed based upon 1533 observations of pronghorns located on...
A study of the life history, population dynamics, and ecological relationships of the Columbian white-tailed deer (Odocoileus virginiarius leucurus) was conducted on the
Washington mainland, Columbian White-tailed Deer National Wildlife Refuge during 1972-1973 to provide information for management of this endangered subspecies. A total of 18,077 observations of deer recorded...
Randomized trials are the gold standard for the clinical assessment of a new treatment
compared to a placebo or standard of care. Often in clinical trials, patients are
accrued sequentially rather than all at once. Thus, the data from such a trial becomes
available sequentially to the researcher. Monitoring and...
