Influence of honey mesquite and its control on zonal vegetation patterns
(1978)
A study initiated in 1973 explored relationships between honey mesquite (Prosopis glandulosa Torr. var. qlandulosa) and understory vegetation on a deep hardland range site in northcentral Texas. Forage production and ...
Effect of calcium levels, appetite enhancers and endoparasites on egg shell quality and performance of laying hens
(1978)
Economy of egg production is greatly affected by the quality of the egg shell and its ability ot withstand shock and resist breakage. The egg industry loses no less than 250 million dollars annually because of egg breakage ...
Characterization of the cell-mediated immune response to Listeria monocytogenes in the murine BALB/c model
(1978)
This research was designed to characterize the in vivo and in vitro immune responsiveness of the BALB/c strain of mice to the facultative intracellular parasite Listeria monocytogenes. It was found in this model system ...
A search for plasmid-mediated phenomena associated with the pathogenicity of Yersinia enterocolitica and Vibrio parahaemolyticus
(1978)
Vibrio parahaemolyticus and Yersinia enterocolitica are two recently recognized enteric pathogens. Each of these species consists of pathogenic and non-pathogenic biotypes. At the present time, there is no reliable method ...
Study of low energy charge transfer collisions using a radio-frequency quadrupole ion trap
(1978)
This experiment has measured the spin independent total charge transfer cross section for helium ions interacting with cesium atoms for an energy range between 0.1 and 1.0 electron volt. The result of this measurement of ...
A stochastic network simulation model for the Texas certificate of need review process as relates to general hospital bed expansion
(1978)
A review of the literature related to hospital utilization as well as the Texas Certificate of Need (CON) process revealed no comprehensive, consistent method for reviewing CON applications. To overcome this deficiency in ...
Multiplanar extension of nonplanar directed graphs
(1978)
An analysis of planar and nonplanar aspects of program flow is presented. Basic blocks of computer programs are treated as vertices in a directed graph. Nonplanar programs are embedded in multiple planes. Elements of graph ...
Optimization of large scale 0-1 integer linear programming problems with multiple-choice constraints
(1978)
In many capital budgeting decision making situations, the decision problem may be formulated as a 0-1 integer linear programming problem with multiple-choice constraints. An example of this formulation is a model of the ...
Mesoscale thermal structure of the polar front zone in Drake Passage during the austral summer of 1976
(1978)
The boundary between the Subantarctic and Antarctic surface waters within the Southern Ocean is known as the Polar Front. This front lies within a complex transition region referred to as the Polar Front Zone (PFZ). The ...
