The bionomics and ecology of Culex salinarius Coq. (Diptera: Culicidae) in Chambers County, Texas
(1991)
In Chambers County, Texas, Culex salinarius larvae were widely distributed and found in a variety of aquatic habitats during cooler times of the year. However, during the summer they were generally restricted to cool aquatic ...
Semi-automatic analysis of the ocular pursuit response during ethanol intoxication
(1993)
Alcohol disrupts the normal function of the oculomotor system causing involuntary abnormal oculomotor responses, generically labeled as alcohol nystagmus. Four distinct ethanol-induced, ocular responses have been described ...
Analysis of laser's relative intensity noise and multichannel intermodulation distortion for subcarrier multiplexed transmission systems
(1993)
The source laser's relative intensity noise (RIN) and intermodulation distortion (IMD) are two very important system design considerations in fiber optic communication systems, especially in subcarrier multiplexed (SCM) ...
Quantum amplifier model for semiconductor lasers
(1991)
A quantum amplifier model for semiconductor lasers is developed in this dissertation. This model is capable of predicting the temporal variations of optical output power from semiconductor lasers on a picosecond time scale. ...
Parameter estimation for compartmental mixture models
(1991)
Compartmental models are widely used in many applications, including pharmacokinetics, phisiology, sociology, and ecosystem modeling. Stochasticity may be introduced into a compartment system in many ways. In some instances, ...
Influence of selected spray diluents on the efficacy of n- cyhalothrin against Heliothis virescens larvae (Lepidoptera: Noctuidae)
(1993)
Insecticides have been applied to cotton in combination with a variety of diluents and agrichemicals. Preliminary studies suggested that one agrichemical or diluent can improve, have no effect, or decrease insecticidal ...
A transformation technique for imaging offset VSP
(1991)
The objective of this research was to develop a transformation procedure to image offset VSP. The transformed VSP is readily interpretable and easier to tie with surface seismic. A model-dependent transformation approach ...
An investigation of psychosocial variables related to academic achievement among fourth and fifth grade African American males
(1991)
Exploratory in nature, this study was conducted in response to the increased problems that African American males are experiencing in their educational pursuits. The child development literature suggests a differential ...
A comparison of administrator and research expectations for the twenty-first century middle school science and mathematics programs in Texas
(1993)
The purpose of this study was to compare the responses of selected Texas school administrators and researchers to expectations for middle school science and mathematics programs in the twenty-first century. The responses ...
Association of sheath and navel score with growth and sale price in Beefmaster cattle
(1990)
Field data were collected on Beefmaster cattle from three central Texas ranches and three Beefmaster auction sales. Statistical analysis was performed on these data to evaluate the effects of: year, herd, sire, sex of calf, ...
