Systematics of Cicindela rufiventris Dejean, Cicindela sedecimpunctata Klug and Cicindela flohri Bates (Coleoptera, Cicindelidae)
(1980)
Morphological characters of the 48 species in the Cicindela subgenus Cicindelidia were analyzed cladistically. The results of this analysis indicate that Cicindelidia is composed of 6 species lineages. Within this group, ...
Economic and fiscal impacts of lignite development for the Brazos Valley Economy of Texas
(1980)
The purpose of this study is to estimate the economic and fiscal impacts of lignite development for the Brazos Valley Economy of Texas for 1977 through 1999. A regional economic-demographic model was used to analyze the ...
The career patterns and intragenerational mobility processes for mature American women
(1980)
Based on data from the National Longitudinal Surveys of Work Experience, this research assesses three major life career patterns for mature American women: home, labor force, and mixed careers. The research then evaluates ...
Probabilistic analysis of foundation forces for a class of unbalanced rotating machines
(1980)
This dissertation considers the problem of the foundation force of an unbalanced rotating machine from both deterministic and probabilistic viewpoints. The rotor-housing is modeled as a three degree-of-freedom system wherein ...
The effect of electrical stimulation and postmortem time on properties of the sarcoplasmic reticulum
(1980)
The left sides of six mature (USDA E-Maturity) cattle were electrically stimulated with 18 impulses of approximately 500 volts. The right sides of the carcasses served as controls (NS). Samples (200 g) were excised at 0 ...
The impact of the 1977 Food and Agriculture Act on cotton production in the United States : a simulation of policy alternatives
(1980)
This study estimates the probable impacts of seven alternative cotton policy scenarios on the crop production industry in the Cotton Belt region of the United States. A belt-wide, regional linear programming model of crop ...
Training pre-service teachers to use positive reinforcement : influences of depicted events
(1980)

An examination and comparison of two sampling procedures for estimating the reliability and amount of error in an information processing system
(1980)
This dissertation answers several questions on sampling and estimation in information processing systems that are in series with k-steps. Two sampling schemes, sampling each step and sampling only output, are investigated. ...
²⁵²Cf-plasma desorption mass spectrometry of chemically protected ribo- and deoxyribooligonucleotides
(1980)
A new method of determining the base sequence, the purity and the molecular weight of a chemically protected ribo- or deoxyribooligonucleotide is described. Using the method ²⁵²Cf-plasma desorption mass spectrometry positive ...
Insecticide synergism by chlordimeform : nature and mechanism(s) of action
(1980)
The nature of insecticide synergism by chlordimeform (CDF) was studied with emphasis on the biochemical mechanism by which this interaction could be achieved. Insects used in these studies were the tobacco budworm, Heliothis ...
