Approximating soil loss calculations with satellite data and multivariate regression analyses

Description: Digital satellite remote sensing and Geographic Information Systems (GIS) have been used effectively to determine the Universal Soil Loss Equation (USLE) output for a number of North Texas watersheds. This method involves determining the values of each of the USLE factors and using these factors as information layers within the GIS.

Determination of Neuronal Morphology in Spinal Monolayer Cultures

Description: The objective of the completed research was to characterize the morphology of individual neurons within monolayer networks of fetal mouse spinal tissue via intraperikaryal injections of horseradish peroxidase (HRP). Thirty labelled neurons were reconstructed via camera lucida drawings and morphometrically analyzed.

Estimating Nonpoint Source Pollution in North Texas Watersheds through Remote Sensing and Geographic Information Systems

Description: Monitoring nonpoint source pollution in a large area is often impractical. However, estimating nonpoint pollution through use of empirical models such as the Universal Soil Loss Equation (USLE) provides a basis for identifying problem areas, and setting management priorities. The purpose of this study was to determine the feasibility of using Landsat imagery and existing geographic data to estimate the effects of land use changes on water quality in four North Texas watersheds over a twelve yea… more

Isolation of the xylE-xylL region of Pseudomonas putida plasmid pDKR1 and determination of the complete nucleotide sequence of the xylE gene encoding catechol 2,3-dioxygenase

Description: A 5.1 kbEcoR I fragment from Pseudomonas putida TOL plsmid pDKR1, carrying the xylE and xylL genes, was inserted into pBR 325 and transformed into E. coli. The xylE region, coding for catechol 2,3-dioxygenase, was subjected to Maxam-Gilbert sequencing reactions.

Localization of serotonin (5-hydroxytryptamine, 5-HT) with partial purification and characterization of a serotonin binding protein in the intestinal tissue of the nematode Ascaris suum

Description: Muscle, hypodermis and gastrointestinal epithelium from adult female Ascaris lumricoides var. summ were found to contain serotonin based upon glyoxylic acid induced histofluorescence and indirect immunolabeling with an anti-serotonin monoclonal antibody conjugated to protein A-colloidal gold.
