No-till pasture renovation can increase the quality and forage yield of underproductive pastures. Decreased erosion, lower costs, and less lost grazing time are advantages of no-till renovation compared to conventional renovation. Unwanted vegetation is first controlled with herbicides to decrease competition for introduced orchardgrass. Two field trials were conducted using...
A mathematical model is developed for the analysis of circular
cell bulkheads subjected to gravity loads of cell fill, backfill, lateral
pressure, and surcharge load using the finite element method. The
finite element circular cell model consists of axisymmetric triangular
and/or quadrilateral ring elements for soil and cylindrical shell elements...
Circular dichroism (CD) spectra were obtained for bacteriophage T4 lysozyme and three of its mutants in the presence and absence of colloidal silica nanoparticles. Mutant lysozymes were produced by substitution of the isoleucine at position 3 with tryptophan, cysteine and leucine. Each substitution resulted in an altered structural stability, quantified...
The number of international inbound tourists to the United States has risen steadily. To serve these and other tourists best, traffic signs need to communicate information correctly across a potential language barrier. Of particular interest is the traffic sign intended to communicate directions to Tourist Information centers. While the general...
Independent systems theory has been used to interpret the
circular dichroism (CD) spectra in the vacuum uv of three cyclic
dimers of amino acids. First, the theory for rotational strengths is
developed in terms of degenerate and nondegenerate group functions.
All terms to first order in perturbation theory are kept....
This dissertation treats information theory and its applications
to the general area of decision making. Specifically, three areas are
covered; (1) information theory applied to Bayesian analysis,
(2) estimation using multi-factor information channel models, and
(3) information theory applied to Markov chain analysis.
A major portion of this dissertation concerns...
A single cell in a 12 cell bulkhead was instrumented to observe
its behavior and confirm design assumptions during construction.
Vibrating wire strain gages were employed to measure horizontal
strains in sheetpiling webs. These were converted to interlock
force at eight locations and three elevations around the cell. The
deformed...
Most data are associated with a place, and many are also associated with a moment in time, a time interval, or another linked temporal component. Spatiotemporal data (i.e., data with elements of both space and time) can be used to assess movement or change over time in a particular location,...
