Increased
traffic in Pakistan speeds up pavement deterioration, and the country lacks
the considerable resources needed to maintain its road—$100 million per year
in a study by
Gilbert Baladi and Pakistani colleagues. Asphalt recycling—reusing
roadway materials to reconstruct or rehabilitate pavements—offers both
economic and environmental benefits. Experience with the process in the U.S.
suggests it would work in the climate extremes of Pakistan.
When
Bruce Dale
analyzed methods of producing corn for use in making biofuels, he found that
a lot of nitrous oxide, a potent greenhouse gas, was generated. He also
found that modifications to farming practices—growing winter cover crops,
for example—could reduce that negative environmental impact. So did using
corn stalks for cellulosic ethanol, which has the added advantage of leaving
the grain for feeding animals and people.
Military
vehicles need to be light enough for transport; easy to assemble in the
field; and able to endure heat, sand, and explosive devices. Design
solutions that meet those needs will improve civilian vehicles of all kinds,
too. Gary Cloud leads a
team with expertise in vehicle safety, self-diagnostic materials, and
composite materials that blend plastics and ceramics with fiberglass or
graphite for strength and durability.
A predator’s impact appears in how its prey adapts to
avoid being eaten as well as in how many of its prey it eats. When the spiny
water flea invaded the Great Lakes, smaller daphnia retreated to deeper
water. But the colder habitat was less conducive to reproduction, creating a
long-term negative impact. Scott
Peacor found that such a change can have a greater overall effect on
a species—as much as ten times greater—than being eaten.
Studies of automobile engine efficiency, vehicle
emissions, and alternative energy sources are under way in the recently
opened Energy and Automotive Research Laboratories.
Eann Patterson
identifies hybrid technologies, collection of waste heat for conversion to
electricity, and subzero testing in a cold start room as some of the
projects being addressed by a cross-disciplinary group of faculty to support
the energy and automotive industries. |
