Health center sponsors
weight-loss program

Beginning Sept. 30, students with
weight problems can attend weekly
meetings of the University Health
Center weight control group.
The group will meet every Monday,
3:30 to 4:30 p.m., for 10 weeks. The
program is offered each semester.
Students wishing to join the group
must have a physical examination to
determine if they are at least 15 percent
overweight. Then they are referred to a
dietician who works with them before
and during the 10-weeks. The group is
limited to 25 people.
Kathleen Lehr, health center dieti
cian said the health center sponsors
the group to help students develop
healthier lifestyles. She said the pro

and behavior modification.
Each weekly meeting includes a
weigh-in, informal discussion on the
students' progress, and a speaker, Lehr
said.
Dr. Garland Bare coordinates the
group. He said anyone can lose weight
if they learn how.
Bare said this weight control group
is different from many others because
it emphasizes long-term weight control
rather than quick dieting.
Students pay a $25 fee at the first
meeting, Lehr said, but up to $20 can
be refunded based on meeting attend
ance and completion of assignments.
A staff and faculty group also will
meet on Tuesday, noon to 1 p.m.,
beginning Oct. 1. For information about
both groups, contact a registered die
tician at 472-7447.

UNL invention helps experts
study past through ice samples

A solar-powered ice drill invented by
a UNL senior engineer enabled scient
ists to study past and present world
climates by analyzing ice core samples.
The solar-powered ice drill is a

tor Bruce Koci of the UNL Polar Ice
Coring Office.
Koci said solar energy is an "ideal
power source" for the drill.
The drill uses 48 solar panels to melt
through ice sheets. The failure rate for
solar panels is low and they work better
at colder temperatures and higher cli
mates, he said.
Although the drilling equipment
weighs about 2,000 pounds, it can be
dismantled and carried in about 60
trips, Koci said. Helicopters can't
transport standard drilling equipment
there because the air is too thin, he
said.
He said many things can be disco
vered through ice core samples. In
addition to climate changes, it may be
possible to study volcanic events and
predict possible world droughts, Koci
said.
"Ice is a storehouse of information,"
Koci said.
The ice core samples taken in the
summer of 1983 on the Quedccaya ice
cap in Peru are seven feet long and
about 1,000 years old, he said. This was
the first time samples this deep were
taken from the equator.
Two samples were taken for compar
ison. Both showed a volcanic eruption
in the same year.

"The record is phenomenal," Koci
said.
"Ice samples are like tree rings, he
said. They have striped portions that
contain dust particles and varying
amounts of carbon dioxide.
The National Science Foundation
hires the ice coring office to do expedi
tions. The office also monitors glaciers
and designs equipment for expeditions.
Office staff members are experiment
ing with geodesic dome shelters built
for Artie conditions.
"It's pretty exciting working with
scientists from all over the world,"
Koci said.
Most of the expeditions have been to
Antartica and Greenland.
They begin in late October and con
tinue through February. Koci said these
months are the warmest season in the
artic regions. A nice day would be
about 10 degrees Fahrenheit, he said.
The office is working on a drill that
could get samples from 10,000 feet or
more below the surface, Koci said. The
multi-million dollar project is set for
next year, he said.
Last year the office received almost
$1 million, the biggest grant at UNL. If
next year's Greenland expedition is
successful, the grant could double,
Koci said.

GTA, she said.
Once the GTA is selected, a supervi
sor is assigned. Supervisors monitor
performance by visiting classrooms,
reviewing prepared materials and in
stucting weekly seminars on teaching
techniques.
"There is some intrinsic interest on
the part of the teaching assistant,'
Santmire said. "They tend to be more
empathetic and interested in helping
students."
