Sleep is
one way
to 'cram,'
doctor s ays
By Linda Hartmann
Staff Reporter
Imagine Steve, a weaiy college
student, sitting at his desk at 4:30
a.m. One hand holds up his head,
the other turns the pages of the
book he neglected to read during
the semester's first 10 weeks.
Tomorrow is the big test, and Steve
doesn't have time to sleep. He'll fail
if he doesn't study.
But Steve -may be doing more
harm than good. He may fail the test
anyway.
Dr. Gerald Fleischli, medical
director of the University Health
Center, said there are two reasons
Steve may not remember most of the
test material: his studying is overly
concentrated and he is fatigued.
Fleischli said people can't study
effectively when they memorize large
amounts of material all at once.
Studies show that small, repeated
doses of studying help people retain
more material than do hours and
hours of concentrated studying, he
said.
Loss of retention also is caused
by "the fatigue factor," Fleischli
said. Tired people's minds wander
and they waste time. They cannot
think as clearly and logically as
people who are well-rested, he said.
In Steve's case, he may have done
Campus computers
need proper climate,
spokesman says
By Martha Miller

Computers on the UNL campus must
be operated in rooms with mild temp
eratures,' a spokesman for the UNL
physical plant administration said
Thursday.
John Amend, assistant director of
the plant, said computer systems should
be in an air-conditioned room for proper
maintenance. He said the exact temp
erature varies depending on the size
and type of computer.
Doug Gale, director of UNL's com
puting resource center, said there are
11 "large-site" computers on campus
and more than a dozen smaller-scale
computers in each department, not
counting the personal computers. Gale
said it would be impossible to count
the total number of computers on
campus.
"It would be like trying to guess how
many desks there are on campus," he
said.
Two of the largest computer sys
tems, Gale said, are the CDC a?.d VAX
computers in the Walter Scott Engi
neering Center and the IBM computer
in Nebraska Hall. Both systems are
being monitored, he said.
Virgil Ward, director of campus
operations at the computer resource
center, said the air conditioners for the
larger computers are "state of the art."
He said that in addition to monitoring
temperatures, the air conditioner con
trols humidity. Ward said that without
the air conditioner, moisture would
collect on the electronic circuitry like
water collects on a cold glass of liquid.
"The condensation would damage
the system," he said.

all the reading, but he'll be too tired
to apply what he read on the test.
In extreme cases, when people
stay awake for several days, they can
have hallucinations and feelings of
paranoia, Fleischli said.
Sleep is also an important part of
the memorization process, Fleischli
said. As people sleep, the brain
actually "pigeonholes" the expe
riences of their day into appropriate
memory slots. If people study but
don't sleep afterward, this process
can't occur and a certain amount of
The air conditioner in the resource
center is operated year-round.
Gale said most computers on cam
pus are micro-computers. The temper
ature control needed for these systems
depends on the room they are located
in. Some micro-computers or "smaller
scale" systems are in Ferguson Hall,
Behlan Physics Laboratory, Love Library
and the Nebraska Union bookstore.
"If you hive a room with 30 termi
nals and 30 people are on each termi
nal, plus lots of windows in the room,
the temperature will be uncomforta
ble, he said.
"People are very nice little heat
engines," he said.
. . A micro-computer will live the long
est in a room that is comfortable for
most people, Gale said. He said that if
the room temperature feels uncomfor
table, it is probably inadequate for the
computers.
The cost of installing a separate air
conditioner for large-scale computers
is expensive, Gale said. Depending on
each individual case, Gale said, com
puter installation can range from two
or three hundred dollars to $15,000.
The most expensive air conditioning
systems are for the larger computers
because they are central air condition
ers. Gale said air conditioners that set
in windows are cheap up front but are
not efficient for a large system in the
long run.
Amend said the plant does preven
tive maintenance on almost every item
at UNL He said the routine service
costs individual departments one or
two hundred dollars a year. Changing
the filters and fans regularly is cheaper
than having to pay for a major repair
when the system completely breaks
down, Amend said.
"It's money well spent," he said.

information will be lost, he said.
Fleischli advised alternating
studying and sleeping if students
need to 'cram' for a test.
And during his long night, Steve
might try consuming more caffeine
or smoking more cigarettes to help
him stay awake. Fleischli said an
excess of both can cause stomach
problems and gastritis.
"Good study habits begin right at
the beginning of the semester," he
said. "The key is preparing for a big
test throughout the semester."

Pershing Rifles meet
at UNL for convention
From Staff Reports
Nine regimental commanders from
across the nation attended the 1935
Pershing Rifles National Convention at
UNL Saturday.
Lt. Gov. Don McGinley spoke at the
convention in the East Union.
According to EmmaFristoe, national
finance officer, Pershing Rifles is a
national military honor society named
in honor of Gen. John J. Pershing.
Pershing was a UNL military science
professor.
The convention, held annually at

typing in the word MAIL and asking for
information on the program, Kutish
said. The other two CDC modes will be
hooked up to BITNET in December, he
said.
People still are learning about the
network, and the potential is unlim

The system is very reliable and the
chance of losing information within the
network is small, he said.
"I suspect in the next five years or so
you'll find no university not hooked up
to BITNET," Ruhrdanz said. "It's kind
of a way of meeting a lot of people
across the world."
