Gamma-gamma directional correlation study of barium-134

Creator:: Coleman, Lamar William
Abstract:: Gamma-gamma directional correlations were measured in Ba¹³⁴ at ten angles between 90 degrees and 180 degrees in ten degree increments using a scintillation spectrometer. The spectrometer which used NaI crystals, differential energy selection, and standard coincidence techniques was tested by measuring the directional correlation of the two cascade gamma rays...

Development of a test procedure for water sensitivity of asphalt concrete mixtures

Creator:: Al-Swailmi, Saleh H.
Abstract:: 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...

Cultural controls for suppressing Phytophthora cinnamomi root rot of blueberry

Creator:: Yeo, John R.
Abstract:: Phytophthora cinnamomi is a soilborne pathogen that causes root rot disease of highbush blueberry (Vaccinium corymbosum L.). When new installations of susceptible blueberry cultivars are infected with P. cinnamomi, plants often fail to grow significant new tissue, greatly reducing yields over the life of the planting. Chemical fungicides are available...

Development of performance based test procedures for asphalt mixtures

Creator:: Kliewer, Julie E.
Abstract:: In 1987, Congress authorized a 5 year $150 million dollar research program called the Strategic Highway Research Program (SHRP). SHRP was divided into four major areas, including the asphalt research program. The asphalt research program was divided into six major research contracts, one such contract, SHRP-003A was called Performance Related...

Adolescent Mental Health and Well-Being: Examining the Role of U.S. Public Education Policy and School Climate

Creator:: Hommel, Annie
Abstract:: This dissertation seeks to contribute to a growing body of research on student outcomes by way of a public health perspective examining the intersection of education policy and adolescent mental health and well-being. The conceptual approach underpinning this project rests on the key theoretical assumption that education policy, shaped at...

The Influence of Microbial Communities on Spatiotemporal Elemental Cycling in Coastal Margins Revealed by Community- and Population-level Genomics and Proteomics

Creator:: Kieft, Brandon P.
Abstract:: Biotic and abiotic processes at continent-ocean interfaces cycle a disproportionate mass of carbon and nutrients relative to their global surface area, and microbial activity is a principal determinant of organic and inorganic matter flux in these transition zones. Most studies using modern high-throughput ‘omics techniques to link microorganisms with costal...

Molecular and physiological aspects of maize embryo maturation

Creator:: White, Constance N.
Abstract:: Experiments were performed to assess regulatory factors governing maize embryo maturation and vivipary. Both visual and molecular markers of embryo development were used to examine the roles of the hormones abscisic acid (ABA) and gibberellins (GAs), as well as water stress in governing transit from early embryogeny to maturation-phase development....

Development of predictive mapping techniques for soil survey and salinity mapping

Creator:: Elnaggar, Abdelhamid A.
Abstract:: Conventional soil maps represent a valuable source of information about soil characteristics, however they are subjective, very expensive, and time-consuming to prepare. Also, they do not include explicit information about the conceptual mental model used in developing them nor information about their accuracy, in addition to the error associated with...
