Unusual Bicycle
Used For Tests
By TOM CURL
A physical education graduate
student ait A&M uses a bicycle
for something besides getting to
class or skinning knees and el
bows.
Earl Yarbrough, a weight train
ing instructor and a student, is
working on a project of determin
ing heartbeat reactions to in
creased resistance. The bicycle is
more properly called an “ergo-
meter.” The unit is stationary and
has no spoked wheels ; only a large
flywheel with a tension band that
can be tightened to increase resis
tance on the pedals.
Yarbrough had a two-fold pur
pose in starting this particular
project. He wanted to use it as
the object of a problem course
in his graduate work and also
he hopes to base his Ph.D. dis
sertation on the results of the
work.
Using volunteer subjects, Yar
brough has made about 55 tests
since he started in April.
The test involves the subject
being fitted with chest electrodes
that are connected to a physio-
graph, a device used 1 to measure
rate of heartbeat and recorded
as an electrocardiogram (EKG).
The person then pedals the bicycle
ergometer at the rate of 50 times
per minute in cadence with a
musical metronome.
The actual goal is to determine
the amount of resistance needed
to bring the average person’s
heart rate up to a level 125 to
145 beats per minute.
Yarbrough records the rate of
heartbeat every thirty seconds
until the rate levels off. Some
tests involve a Constance resist
ance while in others the resist
ance is gradually increased to
observe the effect on the heart.
All tests are stopped when the
heart beat rate reaches 160 beats
per minute.
Yarbrough has noticed that
some of the EKG graph lines
jump sharply due to emotional
reaction,
“Perhaps I would have a fresh
man on the machine and an upper
classman would walk in; or some

To Join Faculty
Of Chemistry Dept.
Dr. Wallace M. Pasika will join
the Texas A&M Chemistry De
partment faculty June 1 as an
associate professor, announced
Dr. A. E. Martell, head.
Pasika, 34, has been a faculty
member at East Texas State since
1965.
The physical chemist obtained
bachelor and master’s degrees at
the University of Manitoba and
the Ph.D. at the University of
Alberta, Canada.
other emotional factor would
cause the heart rate to momen
tarily jump,” he remarked.
In addition to emotional stress
es affecting heart rate, Yarbrough
said that heart rate is difficult to
measure in people who have non-
rythmic heartbeats.
Three Officers
Reassigned
To S. E. Asia
Three Air Force officers cur
rently assigned at Texas A&M
will move to new jobs in South
east Asia this summer.
Maj. Deward Johnson, Maj.
Philip ' I. Caleb Jr. and Capt.
Samuel J. (Joe) Boles Jr. are Air
Force ROTC instructors.
Johnson and Caleb will be re
assigned in South Vietnam and
Boles will be stationed at Korat,
Thailand.
Boles, the operations staff
officer-to-be at the 7th Air Force
headquarters, Tan Son Nhut AB
is married and has two children.
He came to A&M in 1965. In
addition to instructor duties, the
Versailles, Ky., native has been
Boy Scout liaison officer and in
structor pilot, information and
safety officer of the detachment.
Johnson supervised student
pilots as flight instruction pro
gram project officer and was
military advisor to the 4th
Group, President’s Flag winner;
Squadron 13, Academic Achieve
ment award unit, and Squadron
11, winner of the General Moore
and Spencer J. Buchanan awards.
Major Caleb hopes to complete
master’s degree work in history
before leaving A&M in August.
He will be an AC-47 Dragonship
crew member with the 5th Air
Commando Squadron at Nha
Trang, Vietnam.
Training at Fairchild AFB,
Wash., England AFB, La., and
Clark Field, Philippines, will pre
cede his assignment. The father
of two children, Caleb has been
at A&M four years and is a mem
ber of St. Thomas Episcopal
Church.
Captain Boles will be reas
signed as a 553rd Reconnaissance
Wing navigator, flying out of the
Royal Thai AB. Instructor of
junior and freshman aerospace
studies, he has been Wings and
Sabres advisor, Squadron 2 mili
tary advisor and taught naviga
tion in the flight instruction pro
gram. Boles, the father of four,
is detachment testing officer and
AFROTC project officer of new
student summer conferences.
The three officers were hon-
orees of a recent detachment fare

LIGHTS BOOST LIVING
Making night driving almost as safe as day driving is a
goal of Texas Transportation Institute researchers at
Texas A&M University. Mrs. Ray Stanford Jr. jots notes
as Dr. Neil Rowan and Ned Walton inspect ten 1,000-watt
lights soon to be installed atop a 100-foot pole for further
research at A&M’s Research Annex.
Dr. Claude Hall Wins Award
Unique Lighting
May Ease Driving
Prof. Claude H. Hall of Texas
A&M’s History Department has
won the $100 award for the best
scholarly article published in the
“Southwestern Historical Quar
terly,” Dr. J. M. Nance, depart
ment head, announced.
The H. Bailey Carroll award
was established last year. Hall,
as the first recipient, received
it at the annual meeting of the
Texas State Historical Associ
ation in San Antonio over the
weekend.
The av^ard went to Hall for his
article on “The Fabulous Tom
Ochiltree: Promoter, Politician
and Raconteur,” which appeared
in the January issue of the quar
terly. The article is based on the
extensive research that he has
been engaged in for several years
of “Texans in Congress.”
“We are proud that a member
of the A&M history faculty has
achieved such recognition for his
writing and scholarship,” Dr.
Nance said.
Others attending the meeting
in San Antonio from the A&M
department included Dr. Nance;
Dr. Thomas L. Miller, associate
professor, and Dr. Victor H.
Treat, assistant professor. Dr.
Nance is a member of the associ
ation’s executive committee.
Who says there is nothing new
under the sun?
Texas A&M researchers are
working to make night highway
driving as safe as day driving
for the nation’s motorists. Their
ideas are being put to practical
use in San Antonio, Texarakana,
Sioux Falls and Rapid City, South
Dakota.
Better illumination is the an
swer Dr. Neilon J. Rowan and
Ned E. Walton have come up
with afte four and one-half
years of research. Rowan heads
the Texas Transportation Insti
tute’s Driving Environment pro
gram. Walton is a research as
sistant.
“We are trying to reproduce
as nearly as possible seeing con
ditions for night drivers that
are experienced by daytime
drivers,” Rowan emphasized.
“Achieving daylight intensity of
light is not our objective. But
we wan uminate entire in
terchange areas sufficiently so
drivers may see roadway features
necessary for safe driving.”
Rowan said drivers need to
readily see all interchange road
ways, signs, guardrails, curbs and
other things to quickly and calmly
make numerous decisions which
contribute to safe driving in in
terchange areas.
Floodlighting is not exactly
unique, Rowan hastens to note.
It is, he said, new in its form of
application to roadway lighting
in that less illumination is re
quired for functional efficiency.
Floodlights, familiar sights in
sports and industry, may soon
become even more notable along
the country’s highways, the re
searcher feels.
“Our research is sponsored by
the Texas Highway Department
in cooperation with the Bureau
of Public Roads’ Department of
Transportation,” Rowan said.
“The cost totals $260,000 to date,
including $82,000 for this year."
Rowan and Walton are not
“talking” fixed mounting heights
now although they readily admit
poles may range from 80 to 150
feet high, depending on topog.
raphy and other factors.
The 100-foot towers being in-
stalled in San Antonio are de-
signed to withstand 100-mile-per-
hour winds. For safety’s sake,
Rowan explained, the poles are
being mounted 100 feet or more
from the roadway’s edge, making
it highly improbable that they
would be struck by motor ve-
hides.
Researchers’ quest for safety
doesn’t end there. They are work
ing on shock absorbing devices
which may be placed around poles
to reduce probability of injuries
to drivers and passengers if their
vehicle should crash into the
towers. Rowan said TTI research,
ers already have devised impact
attenuation devices which will
stop a car traveling 60 miles per
hour in 15 feet. This type col
lision, he added, is considered a
survivable accident.
According to Rowan, use of
lower mounted lighting systems
in interchange areas light only
individual roadways and as a
result do not allow drivers to
see the total picture.
With low mounted lighting,
Rowan added, drivers have diffi
culty determining relationships of
other roadways with the roadway
on which he is driving. Also, he
continued, glare from light
sources on other roadways may
niterfere with his driving and
add to his confusion.
