that to date no toxicity has

tients.”
Honn, associate professor
of radiation oncology, pre
sented his findings at a recent
seminar sponsored by the
American Cancer Society.
Metastasis, or the spread of
cancer, is a major cause of
death among cancer patients,
he said.
“Successful cancer treat
ment is almost impossible
when the cancer cannot be
contained at its primary site,”
he said.
“Early detection followed
by surgical removal and radia
tion have good results. But the
fact is — though most
surgeons don’t like to hear it
— that tumor cells are re
leased during surgical man
ipulation and sent on their
way to invade other parts of
the body.”
The critical step in the cell’s
travels following its release
from the original tumor, he
explained, is its attachment to
a blood vessel wall, where its
growth flourishes. If left to
float through the body’s circu
latory system without being
able to attach to the wall, the
tumor cell could not survive.
The drug prevents the
attachment apparently by sti
mulating the body to produce
prostacyclin, the most potent
agent known to work against
the clustering of platelets.
Student loans followed closely
Uncle Sam after defaulters
United Press International
In Philadelphia last year, U.S.
marshals impounded a dozen
cars, including a snazzy new
Dodge and a recently purchased
S , owned by people who had
tulted on federal student
loans.
A few months later in Los
Angeles, the U.S. attorney’s
office filed suit against 90 stu
dent loan defaulters, many of
them doctors and lawyers.
Nationwide, the government
is in the process of warning
47,000 federal workers that, un
less they soon start repaying de
faulted loans, Uncle Sam will
pocket a hunk of their pay.
The federal government, af
ter years of ineffective prodding
for repayment of student loans,
now is conducting open warfare
against defaulters.
Impounding cars, filing suits
and garnishing wages is part of
the multi-faceted attack against
the estimated 2 million people
who owe $2.5 billion in de-

SPECIAL NOTICE
1st SUMMER SESSION
OPTIONAL BOARD PLAN
Students, on campus, off campus, and graduate, may
dine on a meal plan during the 1st Summer Session at
TAMU. Students selecting the 7-day plan may dine
three meals each day, except Sunday evening: those
selecting the 5-day plan may dine three meals each
day, Monday through Friday. Meals will be served in
Commons. Fees are payable to the Controller of Ac
counts, Fiscal Office, Coke Building.
Notice dates: Commons will be open for cash business
on Registration day, May 30. Meal plans will begin on
the first day of class, May 31.
Fees for each plan are as follows:
7 Day $195.00 May 31 through July 1
5 Day $176.00 and
Plus Tax July 5 and 6
Meal plan validation will begin at 7:30 a.m., May 31, in
the Commons Lobby. Fee slips will be required.

Charles Percy, R-Ill., used to de

pressure from all direc

gave the government added col
lection muscle.
The Debt Collection Act 1982
allows, the government to with
hold 15 percent of a federal em
ployee’s pay as a means of col
lecting a defaulted student loan.
In the past, garnishing federal
wages was prohibited.
Another major provision
allows the government to send
the defaulter’s name, Social
Security number and the size of
his debt to national credit
bureaus, thus applying pressure
on him to pay or get bad credit
ratings.
This winter, notices sent to
defaulters warned that unless
they make arrangements to re
pay the government, a letter will
be sent to credit bureaus.
Percy’s legislation combined
with a 1981 regulation that
turned the screws on colleges.
This measure cut off loan
money to institutions with de
fault rates above 25 percent and
reduced loans to those with rates
of 10 percent to 25 percent.
, “We’re trying to apply press
ure from all directions,” said
Frank Krebs, a member of the
Education Department’s three-
year-old Student Loan Collec
tion Task Force. “We’re out to
collect for Uncle Sam.”
As of June 30, 1981, the most
recent date for which figures are
available, the overall default rate
on $5.7 billion of matured Na
tional Direct Student Loans was
15.37 percent, down 2 percent
from five years earlier.
By getting the money back
into the available student loan
pool, collection efforts are seen
as a way to ease cutbacks in the
student aid being imposed as
part of President Reagan’s over
all austerity program.

In addition, URI is studying
the economics of robots, revis

robot systems and including
machine labor as a fourth cost of
manufacturing.
“These are born numb, dumb
and blind,” Kelley says of robots.
“There are a lot of applications
where that is not sufficient. We
are just beginning now to find
easy and cheap solutions to basic
problems. We’re trying to de
velop the knowledge that says it
is worth the effort.”
Kelley disagrees with critics of
robotics who contend the field
will take jobs away from skilled
workers.
“There will be a negligible im
pact on the workforce. In fact, it
will create jobs because each
robot will need someone to take
care of it; it will mean job
changes, not job eliminations,”
he said.
For example, the Robot Re
search Group currently is using
a brawny, orange Swedish-built
ASERA robot arm with a
40,000-degree plasma arc torch
to clean “grey iron” castings
used in the automotive industry.

after it comes out of the casting
process, is presently cleaned by
