Five strains of the bean pathogen Pseudomonas syringae pv.
phaseolicola were analyzed for plasmid number, size, and relatedness.
Each strain contained one or two indigenous plasmids which ranged in
size from 6.8 to 151 kbp. BamHI and EcoRI restriction patterns revealed that total plasmid DNA from each strain had a...
Transition metal and rare earth element (REE) data are presented
for various sedimentary materials from two Manganese Nodule
Program (MANOP) sites in the eastern tropical Pacific. These data
constrain the sources of elemental supply to the seafloor and the
processes that control ferromanganese nodule genesis. Investigation
of elemental partitioning between...
Six plant pathogenic isolates of Pseudomonas
syringae pv. glycinea, the causal agent of bacterial
blight of Glycine max (L.) Merrill, and one isolate of
P. syringae pv. phaseolicola, the causal agent of halo
blight of Phaseolus vulgaris L., have been examined for
the presence of circular duplex deoxyribonucleic acid
(DNA)....
A method of calculating surface evapotranspiration by separately
including the effects of vegetation and atmospheric evaporative demand
under the condition of nonlimiting soil moisture is presented. A
literature survey is conducted to determine the effects of plants on
evapotranspiration.
To represent the atmospheric evaporative demand, the original
potential evaporation equation...
From the earliest English colonization to the present day, there
has been interest in astronomy in this country. The purpose of this
thesis is to show how the science of astronomy developed in America
from the earliest observations by educated colonists using imported
instruments and publishing in European journals, to...
