Environmental factors such as temperature, air, and water can have a profound
effect on the durability of asphalt concrete mixtures. In mild climates where good
quality aggregates and asphalt cement are available, the major contribution to
deterioration may be due to traffic loading and the resultant distress is manifested
in...

Split and normal gate A1GaAs /GaAs MODFETs were fabricated along with
the ohmic test structures and the Hall bar geometries. The DC characteristics of
normal gate transistors were evaluated at room temperature and at 77K and the
threshold voltages were extracted from the measurements and compared to the
theoretical results....

Thesis research focused on: 1) Water and fertilizer gradients
within the plant root zone, and effects of chemical and physical
gradients on Trichoderma harzianum populations. 2) Regulation of root
growth physically with permeable fabric containers and chemically with
copper compounds. 3) Effects of copper coatings for fabric containers
on Glomus...

Although the Escherichia coli host has almost all of the enzymes necessary to
synthesize nucleotides needed for bacteriophage T4 DNA replication, phage genes
expressed early in infection encode enzymes for de novo DNA precursor biosynthesis
and salvage from degraded host DNA. Eight early enzymes and two host enzymes
comprise the...
