Flood plain regulations are one of six major adjustments
used to cope with flood hazard in the United States. This adjustment
was essentially neglected in the national flood hazard policies
until Congress enacted the National Flood Insurance Act of 1968.
The implementation of regulations, as called for in the Act,...
Involvement has been defined and researched by many student affairs professionals and theorists over the past 40 plus years. While many studies have researched the relationship between involvement and a student's academic success, little research has been done that explores what involvement means to them, and the motivations and factors...
Crown gall was found in numerous pecan orchards in Georgia. In
some instances, 60% of the trees were diseased. Galled trees were
less vigorous than noninfected trees. Among the pathogenic
Agrobacterium strains isolated from 18 galled trees from six
counties, biovar 1 strains predominated and most were sensitive to
agrocin...
The taxonomic status of Microtus canicaudus was compared
with that of a morphologically similar vole, Microtus montanus. Four
means of comparison were utilized: hybridization experiments, comparative
karyology, growth distinctions (total length and body weight),
and qualitative behavioral observations. The hybridization experiments
indicated that, while the incidence of pregnancy of M....
Surface meteorological data collected at a mesonetwork in
Colorado during the 1973 National Hail Research Experiment were
analyzed to see if a diurnal oscillation of boundary layer wind exists
and also to determine the mechanism that drives the wind system.
The average temperature, pressure, and wind velocity for a month's...
In 2013, a large upper-ocean thermal anomaly formed in the Gulf of Alaska (GOA) with sea surface temperatures (SSTs) warmer than 4 degrees Celsius above the climatological norm. This warm anomaly persisted for the next three years and has been linked to downstream effects on North American climate and negative...
Tomato seedlings were used to assay the population of A.
tumefaciens in artificially contaminated soil. Aqueous soil suspensions
were applied directly to the wounded stem. The bioassay was
used because not all pathologically important physiological strains
of A. tumefaciens would grow on any of the selective media available.
This method...
A study was made of compounds produced by Agrobacterium radiobacter
strain 84 that are inhibitory to some pathogenic strains of A.
tumefaciens. Agrocins (inhibitory compounds) were partially purified
from large volumes of A. radiobacter strain 84 culture supernatants to
determine (i) if more than one agrocin is produced, (ii) if...
This study concentrates on analysis of LongEZ aircraft data taken offshore of the Atlantic Coast of the United States. Due to the land structure of the region, it was possible to isolate the effect of narrow land on air as it flows offshore. The narrow land (Outer Banks) separates inland...
Several large-scale marine heatwave events occurred during the last 10 years in the North Pacific. A particular extreme marine heatwave in the North Pacific called the blob created an unprecedented high peak of sea surface temperature (SST) during 2013/14. MHW events had significant impacts on downstream weather and precipitation patterns...
Petroleum mulch applied on the soil surface over a row of
planted seeds promotes a more rapid and a more uniform germination
of seeds, enhances elongation of seedlings and in some cases increases
the yield of the crop. The beneficial effects of petroleum
mulch have usually been attributed to increased...
The stability of steady-state solutions of the equations governing two-dimensional,
homogeneous, incompressible fluid flow are analyzed in the context
of shear-flow in a channel. Both the linear and nonlinear theories are
reviewed and compared. In proving nonlinear stability of an equilibrium,
emphasis is placed on using the stability algorithm developed...
Several horizontal flight segments from SESAME and
ALPEX are studied using structure functions and specral
analysis methods. Theoretical analysis of the relative
errors in structure function and correlation function in
the presence of large scale wave activity is presented. The
effect of stratification and shear on the -5/3 inertial
subrange...
An eigenvector analysis of the velocity-temperature correlation
matrix is applied to clear-air turbulence measured by aircraft in the
Bora. The eigenvectors are identified with the main eddies of the
turbulence. This study attempts to infer the three-dimensional
structure of these eddies. The results are compared with turbulent
structures in the...
The purpose of this study was to use computer analysis of soil and rainfall data to predict the possible occurrence of soil erosion in Central Tunisia. Analysis was done with the program OR-NATURE (M.Ungs et al, 1985) . Central Tunisia was subdivided into northern, central, and southern subzones. Data about...
