Three newborn, colostrum deprived calves were inoculated by the intranasal, intratracheal, conjunctival and oral routes with a subgroup II bovine adenovirus strain 7T. An initial viremia and febrile response occurred in all calves with widespread dissemination of the virus through the body. Clinical signs consisted of pyrexia, soft feces and...
In October 1977, a study was undertaken to determine the role of bovine adenovirus type 3 in enzootic pneumonia of calves, and the efficacy of using a vaccine for prevention of disease. Bovine adenovirus type 3 was isolated from the herd under study in the previous year. Calves in the...
Four bovine adenovirus type 3 isolates, recovered from different areas in Oregon and Washington, were compared antigenically with the original prototype strain which was isolated in England. The fluorescent foci assay method was used to quantitatively establish viral titers. A serum-viral neutralization test was performed with a standard dose of...
Forty-five young adult males were given 30 trials of Isometric
knee extension and 30 trials of isometric knee flexion. Each trial
consisted of a maximum of three second exertion followed by a 10
second intertrial rest interval. Subjects were ranked on the basis
of the mean of the first three...
Forty-five subjects were given 30 trials of isometric elbow flexion
and 30 trials of elbow extension. Each trial consisted of maximum
exertion followed by a short rest in 10 second cycles. Subjects were
ranked on the basis of the addition of the median flexion and extension
scores and were divided...
Forty-eight young adult males were ranked on the basis of mean
hand-grip strength scores and the middle one-third, the medium
strength range, were chosen as subjects. These sixteen subjects were
given 30 serial trials in each of four tests; knee flexion, knee
extension, elbow flexion, and elbow extension. Each trial...
The presence of residual muscular tension has been implicated
as a detrimental influence on the performance and learning of motor
skills. A method for reducing muscular tension has been provided by
the recent advent of biofeedback training. Thirty young adult males
were subjected to tests of stabilometer balancing skill and...
A cinematographic analysis of hurdling technique was completed
using six high school women in the 100 meter hurdle event as
subjects. The study was descriptive in design, intending to make
objective comparisons of selected elements of the hurdling action.
Sixteen hypotheses were developed and tested, in an effort to describe...
Eight male college students served as subjects in an investigation
to establish a procedural model for research of individual motor
units during sustained isometric contractions. Teca TE-4 electromyograph
system with needle electrode provided electrical potential
recordings from active muscle fibers in the right biceps. Various
experimental procedures were tested to...
The primary purpose of this study was to determine the effects
of early morning and evening bouts of aerobic exercise upon the diurnal
pattern of reaction time and body temperature. An effort was
made to classify subjects according to the rhythmic trends identified
with 'morning' and 'evening' type persons.
Eight...
