Phelps, associate professor of visual arts and internationally recognized
photographer, is creating a new documentary survey to mark the bicentennial
of the 1804 Lewis and Clark expedition.
To date, Phelps has created hundreds of panoramic
photographs. By 2004, he plans to have fully documented the trail of the
expedition and organized a book of photographs and a traveling exhibition,
which will open at the Amon Carter Museum in Fort Worth.
Both the exhibition and the book will juxtapose
the photographs with excerpts from the Lewis and Clark journals, creating
a "then and now" context that will highlight the changes time

electronic access to anyone seeking information generated or gathered
by five agencies that have closed since 1996. Records from more defunct
agencies, as well as older issues of the Texas
Register, will be added to the site, which is the only one
of its kind in the nation.
Kelly, head of government documents at UNT, initiated the project, and
Cathy Nelson Hartman, electronic resources coordinator, manages the site.
in the Denton, Dallas and Fort Worth Independent School Districts are
adding to their knowledge of mathematics and physics through the UNT Regional
Collaborative for Excellence in Science Teaching. The teachers come to
campus to receive information about physics experiments for their classrooms,
and they can enroll in one of four UNT physics courses to receive college
credit. The collaborative is co-directed by James Roberts, professor of
physics, and physics alumnus Jamal Hajsaleh.
replacing all of the computer network managers of the world with intelligent,
friendly computer viruses. That's the goal of a UNT professor and graduate
students in the Department of Computer Sciences. They are perfecting software
programs called "intelligent mobile agents" that can think,
work and reproduce on their own.
smart programs may be the caretakers for future networks like the Internet
high bandwidth network between academic and research institutions. These
mobile agents could travel through out
a network to gather requested information and manage the flow of data
while they repair and maintain linked computers.
agents would be intelligent enough to perform these tasks on their own,
producing as many of their kind as needed, says Armin Mikler, assistant
professor of computer sciences.

of chemistry Jeff Kelber and his research team have found that the chemical
bonds of ultrathin oxide films break down when they are exposed to very
high electric fields. The films are commonly used to inhibit corrosion
and in the manufacturing of solid state memory chips and other nanoelectronics.
Kelber, postdoctoral research fellow Noel Magtoto and
graduate students Chengyu Niu and Michelle Anzaldua generated electric
fields, comparable to the forces holding an atom together, using a scanning
tunneling microscope. They discovered that after being subjected to an
electric field, a film's bond between the oxide and metal develops a void
that can grow with the length of exposure to the field. The result is
runaway corrosion or failure of an electronic device.
may experience a surge in savings as the Internet changes where people
choose to live as well as how they live, according to a study by John
Baen, professor of finance, insurance, real estate and law. Baen says
the trend toward employees telecommuting will result in businesses needing
less office space, rotating employees in the same space, and experiencing
less absenteeism and lower turnover rates.
Telecommuting may also change considerations for future
homebuyers, as fewer people will look for homes within comfortable commuting
distance, he says. Many people will leave the cities for the countryside
and rent small condos, apartments or budget hotel rooms in city or suburban
areas for a few days each week or month as a temporary workplace, he adds.
UNT researchers have developed nitrogen
78 percent of the atmosphere
into an alternative to gasoline.
Ordonez, associate professor of physics; Mitty Plummer, associate professor
of engineering technology; and Rick Reidy, assistant professor of materials
science, constructed the CooLN2Car, which is powered from the energy released
when super-cooled compressed liquid nitrogen expands into a gas. The process
is similar to that of a steam engine.
The CooLN2Car currently travels at 36 mph and produces
no emissions that are harmful to the environment. The researchers are
working to improve top speeds.

all birth defects are inherited. Low oxygen and other threats during fetal
development may lead to serious disabilities.
Warren Burggren, professor of biological sciences and
dean of the College of Arts and Sciences, uses emu and chicken eggs to
study the start of heartbeat and blood flow in embryos. He seeks to determine
the extent to which genes and environment shape the development of the
heart, which is the first organ to function in any developing vertebrate.
The research findings may ultimately help to explain,
and possibly correct, birth defects in human hearts.
research of several students resulted in prestigious scholarships this
year. Debra Kay McIlvain, an anthropology major who graduated in August,
received a National Science Foundation Fellowship to continue her study
of the Clovis people
believed by many archaeologists to be the earliest humans in North America.

with glaucoma. Chen developed a model of blood flow to the muscles. A
better understanding of that process is needed to treat diabetes and heart
disease. Flores helped to create a new adhesive to connect bones and prostheses.
It could make metal screws on artificial limbs obsolete and reduce the
risk of infection to bone tissue.
of environmental stimulation and early educational experiences interfere
with normal brain development in children, leading to lost potential and
lower achievement, says George S. Morrison, professor of teacher education
and administration and Velma E. Schmidt chair.
To address that concern, Morrison and his colleagues
developed the Success for Life curriculum, which is based on neuroscience
and child development research. The curriculum applies theory to practice
for the education and whole development of children during the optimum
development period birth
to age 8.
curriculum has eight academic components: literacy, mathematics, music
and fine arts, science, social studies, technology, wellness and healthy
living, and character education. Success for Life is currently used with
more than 4,000 children in more than 50 programs throughout Texas.
resources directors and others who hire new employees may unknowingly
discriminate against job candidates' regional accents, according to Patricia
Cukor-Avila, assistant professor of English. Cukor-Avila and Dianne Markley,
who earned her master's degree in linguistics in August and is UNT director
of cooperative education, created a CD-ROM program featuring 10 males

the United States reading
the same 45-second passage.
Fifty-six job hirers listened to the readers and made judgments about
them based solely on how they sounded.
Hirers gave readers with the least identifiable
accents (California, Minnesota) the highest rating and readers with the
most identifiable accents (New Jersey, Georgia, Louisiana) the lowest
and tetrachloroethylene, used as industrial solvents and as cleaning agents
by dry cleaners, are toxic and can currently be safely destroyed only
by burning. To study ways to make that process more efficient, Paul Marshall,
professor of chemistry, and his research group are examining these substances'
reactions with free radicals atoms
or molecules that have at least one unpaired electron. Marshall's group
investigated these reactions at the molecular level and evaluated how
quickly the substances would be destroyed by flames.

research of Alan Marchand, Regents Professor of chemistry, may lead to
improved water quality in the Rio Grande River, one of the most polluted
ecosystems in the nation.
Marchand and colleague Jennifer Brodbelt of the University
of Texas at Austin designed molecules that bind to heavy metal ion pollutants,
including lead, silver, copper and mercury. The molecules will be introduced
in the river and filtered out to remove the pollutants.

Gear Up offers activities to improve students' technology access and skills
and to acquaint them with role models and mentors. Teachers receive conflict

In its first year, Gear Up is focusing on 400 seventh-graders.
Each year a new group of seventh-graders will be added to the program.
