Allochthonous salt sheets in the Alaminos Canyon region, northwest Gulf of Mexico : present configuration and processes of emplacement
(1989)
Numerous physical and mathematical models have simulated highly mature diapirism in which low density material moves upward through more dense material and then spreads out as a layer known as a canopy (Jackson and Talbot, ...
Cost of production analysis for greenhouse grown foliage plants in the Rio Grande Valley of Texas
(1990)
The Texas Rio Grande Valley Foliage Plant Industry is comprised of a small number of growers producing in adequate, low cost structures. Firm size varies from 50,000 to 1,300,000 square feet of greenhouse space with 87% ...
Physiology of the post-pharyngeal glands and comparative morphology of glands associated with the mouthparts among castes of the red imported fire ant, Solenopsis invicta Buren
(1979)
Morphology has been determined from serial sectioning and dissections of the post-pharyngeal, maxillary, mandibular, and labial glands of the red imported fire ant, Solenopsis invicta Buren. Various parameters such as ...
The technical and safety laboratory teaching competencies needed to teach high school Chemistry I
(1990)
In 1984, the Texas State Board of Education enacted a series of curricular changes in public education. One of the changes mandated that 40% of secondary science class time be spent on "hands- on" activities. The purpose ...
On a robust controller design using a minimax optimization approach
(1991)
An extension of the Linear Quadratic Regulator, and Linear Quadratic Gaussian methodology is proposed to design a robust controller from the viewpoint of eigenvalue sensitivity. The resulting system is optimal under the ...
On the tuning of digitally programmable continuous-time filters
(1991)
Tuning strategies associated with a digitally programmable and reconfigurable continuous-time filter structure which is monolithically implementable and possesses potential for high-frequency precision application are ...
Rational expectations equilibrium in a market with restricted access to differential information
(1991)
This dissertation analyzes a rational expectations equilibrium model of a financial market with two sources of noisy information. Access to the first information source is institutionally limited to a fixed proportion of ...
Synthesis and characterization of conductive polypyrrole - fibrils, composites, films, and powders
(1992)
Template-synthesis, interfacial polymerization, Nafion-modified polymerization, and conventionally electrochemical and chemical methods were used to synthesize polypyrrole (PPy) fibrils, composites, films, and powders. The ...
A computer simulation of populations of the horn fly, Haematobia irritans (L.)
(1977)
The survival of the immature stages of the horn fly, Haematobia irratians (L.), in manure droppings was studied under field conditions in Central Texas during the 1972 and 1973 horn fly seasons. The effect of interspecific ...
Population biology and stand development of birch (Betula pubescens Ehrh.) on disturbed sites in Iceland
(1991)
Deforestation has reduced native birch woodlands and shrublands in Iceland from an estimated 25,000 to 40,000 km^2 at the time of settlement 1100 years ago to about 1,250 km^2presently. The objective of this research was ...
