The effects of long-wavelength infrared radiation on the flying activity of stable flies, Stomoxys calcitrans (L.)
(1969)
Stable flies, Stomoxys calcitrans (L.), were exposed to infrared radiation to determine if they respond to such radiation emitted by cattle and other warm-blooded hosts. The infrared radiation was emitted from a spherical ...
Formulation of a model for packed distillation columns on the basis of field tests
(1969)
On the basis of a series of field tests which were made on a packed distillation column located near Refugio, Texas, several possible methods for the modeling of packed distillation columns were investigated. Because of ...
Studies on some extracellular bacterial proteases
(1969)
The production of extracellular endopeptidase by Aeromonas proteolytica, Merkel et al., was found to be influenced by a number of nutritional factors. There was an inverse relationship between endopeptidase synthesis and ...
An optimal dynamic policy for the design and maintenance of flexible pavements
(1969)
The primary objective of this research is to provide an analytical solution to the optimal flexible pavement design problem. The procedure is based upon empirical equations for deflection, performance, and traffic. These ...
A biosystematic study of the Chloris cucullata-chloris verticillata complex
(1969)
An investigation was undertaken to determine the taxonomic relationships of the Chloris-cucullata-C. verticillata complex and the variation patterns within these populations apparently resulting from hybridization. As ...
The taxonomic status and comparative morphology of species of the genus Neoaplectana Steiner (nematoda: Neoaplectanidae) and the susceptibility of various insect pests to Neoaplectana glaseri Steiner, 1929
(1969)
A clarification of the taxonomic position of the family Neoaplectanidae is presented and the description is emended. The diagnosis of the following twelve nominal species are emended from type material and original ...
Short-term generator commitment to establish a desired system reliability while minimizing system fuel costs
(1969)
A method is described for determining the most economical generating unit commitment policy and loading schedule for a day's operation of an electric utility system while maintaining a desired level of system reliability. ...
Pigment characteristics of the seed of Sorghum bicolor (L.) Moench
(1969)
The location and physical and chemical properties of the pigments in 15 varieties and hybrids of sorghum seeds were investigated. The pigments were found to be located mainly in the stylar area, the epicarp, and the endocarp. ...
Development of a programming language for multistage optimization
(1969)
The primary objective of this research is to provide a user-oriented computer language for multistage optimization. While multistage optimization problems may assume many diversified forms in many areas of application, a ...
The intestinal microflora of turkeys infected with infectious enteritis (bluecomb disease) agent
(1969)
The purpose of this study was to develop techniques for the study of intestinal microflora in avian species, and to compare the intestinal microflora of turkeys challenged with infections enteritis agent with uninoculated ...
