"The scanning electron micro
scope creates public interest be
cause people can relate to the sur
face of an object they know," John !
Brumbaugh, UNL professor of
JUr zoology, said Tuesday.
Brumbaugh said the university
has had a transmission electron
microscope for some time, but the
scanning electron microscope ar
rived last June.
With a scanning electron micro
scope it's possible to look at the
surface of objects, Brumbaugh
said, while the transmission micro
scope looks at thin- slices of
internal structure.
Costs $60,000
The new microscope, manufac
tured by Cambridge, cost about
$60,000, he said. It is in Bessey
Hall.
The microscope sees with elec
trons instead of visible light rays,
Brumbaugh said. The shorter
wavelengths allow you to see
smaller objects than possible with
visible light, he added.
The electrons are emitted from a
gun, focused with electromagnetic
lenses and go through a scanning
coil similar to the scanning coil in a
television tube, Brumbaugh said.

across the specimen. Those that
bounce off are collected and read
out on a modified television screen,
he said.
"It's possible to see a three
dimensional view of the object,"
Brumbaugh said, "and to see the
architecture of anything you can
think of."
The microscope requires training
for use, whether it is personalized
or classroom instruction, Brum
baugh said. Graduate students or
advanced undergraduates who
have been trained are allowed to
use the microscope. Kit Lee is the
chief technician, Brumbaugh
added. .
UNL up-to-date
The scanning electron micro
scope brings the university up to
date and gives it the capability of
doing modern research, Brum
baugh said.
"It allows the university to
compete in teaching and research
with its sister institutions," he
added.
Brumbaugh said the microscope
can also benefit the community.
Other agencies may use the
microscope, and it also has many
industrial uses in quality control,
he added.

UNL teacher inspects POW camps
By John Kaikowski
David Forsythe, associate pro- (J
fessor of political science, had his
share of high adventure when he
visited Africa last summer as a
consultant to the all-Swiss Inter
national Committee of the Red
Cross (ICRC), based in Geneva,
Switzerland.
One of the major responsibilities
of the ICRC is the supervision of
detention facilities for prisoners of
war, political prisoners and "ad
ministrative detainees" through
out the world, Forsythe said.
With a committee observer, he
took seven-hour jeep trip deep
into tr.e bush country of Zaire,
formerly Belgian Congo, to check
the conditions of Portugese civil
ians being held there by the
National Liberation Front for An
gola. "We started the trip on high
ways, then dirt roads and finally
into the bush itself," he said. "My
back felt those bumps for a week."
Forsythe also survived a plane
crash on a primitive landinrj strip in
Mozambique.
Research fellowship
He said he first became inter
ested in the ICRC while working on
a disser tat ion.,ip the Middle East.
"Everywhere I toured, I found
references to the ICRC," Tie' said. ' u
In 1972, Forsythe received a
research fellowship from the
United States government to do a
private academic study of the
ICRC.
"The ICRC decided that i would
be useful and I became a part of the
international committee as a con
sultant," he said.
Forsythe explained that the
ICRC is only one group in a larger
group, the League of the Red Ci uss
Societies. The American Red
Cross, the Bulgarian Red Cross
and all other Red Cross groups are
members of the League of Red
Cross Societies, he said.
The Swiss committee received 75
per cent of its operating budget
from the Swiss government, For
sythe said. The rest of its budget
comes from other governments.
According to Forsythe. most of
the remaining 25 per cent is from
Western governments. About one
per cent of the ICRC budget is from
Marxist governments, he said.
Most reports not public
Forsythe said most ICRC reports
are not made public.
"This is the price of getting into
the countries," he said. "Entrance
' ' to the countries is by voluntary
permission from the governments
and they expect the committee to
be discreet."
According to Forsythe, each
report done by the ICRC concern
political prisoners is given to each
of the countries involved.
"Either country can publish the
report, but only if they publish the
entire report and don't lift out
paragraphs favorable to their coun
try," he said.
The ICRC helped with the
exchange of 4he Arab and Isreali
prisoners of war after the 1966 war.
The ICRC also helped to reunite
families in Israeli-occupied terri
tories and help guarantee that
Arab students in Israeli-occupied
areas could attend Arab univer
sities. Forsythe said his experiences
with the ICRC have helped him
provide up-to-date topics for his
political science classes.
"We talk about today's prob
lems as they are, and not in
abstract terms," he said.
