Pyrethroid resistance in flies : development of a resistance monitoring technique and studies on the mechanism of resistance in horn flies and house flies
(1990)
Biotic potentials were measured for susceptible and pyrethroid-resistant horn flies, Haematobia irritans (L.). Resistant horn flies were less fit than susceptible flies. Pyrethroid-resistance was a reproductive disadvantage ...
An experimental comparison of robot kinematic calibration methods
(1992)
It has been shown that the kinematic calibration can help to improve the accuracy of the industrial robot. This research has involved using two different calibration methods, the CMM and VBAT, to calibrate PUMA 560 ...
The effects of the [beta]â‚‚ agonists fenoterol on the contractile and biochemical properties of skeletal muscle
(1990)
The purpose of this study was to determine if long-term administration of the β2 adrenergic agonist, fenoterol, would increase myosin content and peak tetanic tension in skeletal muscle. A group of 26 male grass frogs ...
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 ...
