Nitrogen and phosphorus dynamics in tropical soils of Mali, West Africa
(Texas A&M University, 2000)
Low soil fertility is one of the major biophysical constraints affecting African agriculture. Phosphorus and nitrogen are the two most common limiting nutrients. Before fertility amendment recommendations are made a ...
Validating the use of qualitative ratings of static wrist postures relative to quantitative measurements
(Texas A&M University, 2000)
This study was conducted to determine the accuracy and reliability of observer estimates of varying degrees of static wrist flexion and extension. Observers' classification of various angles of static wrist flexion and ...
Transportation risk assessment for ethanol transport
(2009-05-15)
This research is aimed at assessing the quantitative risks involved with an ethanol
pipeline. Pipelines that run from the Midwest, where the vast majority of ethanol is
produced, to the target areas where reformulated ...
Modeling software artifact count attribute with s-curves
(2009-05-15)
The estimation of software project attributes, such as size, is important for software
project resource planning and process control. However, research regarding software
attribute modeling, such as size, effort, and cost, ...
The impact of ignoring a level of nesting structure in multilevel growth mixture model: a Monte Carlo study
(2009-05-15)
The number of longitudinal studies has increased steadily in various social science
disciplines over the last decade. Growth Mixture Modeling (GMM) has emerged among
the new approaches for analyzing longitudinal data. It ...
Examining the relationship between maternal stressful life events and urogenital infection in preterm birth using a biobehavioral model
(2009-05-15)
This dissertation examined the relationship between maternal stressful
life events and urogenital infection in preterm birth. A systematic literature
review revealed ambivalent findings concerning the relationship ...
Perception of genetic risk in sexual and reproductive decision-making (PGRID) by college students
(2009-05-15)
One psychosocial variable, human mate selection, has been studied extensively
within the field of evolutionary psychology. A question of interest is how
sexual/reproductive decision-making (i.e., dating, marrying, and ...
Creation and maintenance of a communication tree in wireless sensor networks
(2009-05-15)
A local reconfiguration algorithm (INP) for reliable routing in wireless sensor networks that consist of many static (fixed) energy-constrained nodes is introduced in the dissertation. For routing around crash fault nodes, ...
An effective way to reduce residential construction waste: a case study in Texas
(2009-05-15)
This research consists of an investigation on the incidence of residential construction
waste in Texas. Construction waste has proved to have a negative effect on the economic
health of construction companies and on the ...
Spectroscopic and theoretical investigation of selected cyclic and bicyclic molecules in their ground and excited electronic states
(2009-05-15)
The structures, vibrational frequencies, and potential energy functions of several
molecules in their ground and excited electronic states were determined using various
spectroscopic and theoretical methods.
High-level ab ...
