Studies on the adsorption of host antigens by Schistosoma mansoni
(1990)
The trematode parasite Schistosoma mansoni adsorbs a variety of antigens from it's mammalian host. These adsorbed components may play a role in the parasite's ability to escape the host's immune response to the parasite. ...
Heterosis for grain yield and its components in winter by spring wheat hybrids
(1990)
A study of F1 hybrids between hard red winter and hard red spring wheats (Triticum aestivum L.) was conducted to estimate heterosis for grain yield, grain yield components, harvest index, height, and test weight; to note ...
Testing for polynomial regression using nonparametric regression techniques
(1990)
In regression analysis, it is always important to test the validity of the assumed model prior to making inferences regarding the population of interest. In this investigaton, we utilize nonparametric regression techniques ...
Surface electrochemical studies of nitrogen-containing compounds, sulfur-containing compounds and iodine chemisorbed at gold
(1990)
The interactions of smooth polycrystalline Au electrodes with 3,6- dihydroxypyridazine (DHPz), 2,3-dihydroxypyridine (DHPy), pentafluorothiophenol (PFT), 2,5-dihydroxy-4-methylbenzylmercaptan (DMBM), and 2,5-dihydroxythiophenol ...
The social information processing abilities of rejected and nonrejected hyperactive children
(1990)
This study compared the social information processing abilities of select third and fourth grade boys. Children identified for the study included 14 hyperactive/rejected, 29 hyperactive/nonrejected, 14 nonhyperactive/rejected, ...
An empirical Bayes approach to variance function estimation
(1990)
The problem concerns the analysis of assay data when there have been previous similar experiments. Assay data usually fall under the framework of nonlinear regression when the variability about the regression line is ...
Senior citizens as instructional mentors to enhance the secondary school curriculum
(1990)
There is considerable interest in involving senior citizens as active participants in the instruction of secondary school curriculum to utilize the skills, talents, and expertise of this growing segment of the population. ...
Soil water evaporation and transpiration from a row crop at partial cover
(1990)
When crops are cultivated in a row configuration, latent heat flux from the soil (LE[s]) and crop canopy (LE[c]) influence the energy and water balance of the crop. Field experiments were conducted in Lubbock, TX to examine ...
Factors affecting the efficacy of seed safeners against chloroacetamide herbicides in sorghum
(1990)
Seed treatments using cyometrinil, oxabetrinil, and flurazole have effectively safened grain sorghum against chloroacetamide herbicides such as alachlor and metolachlor at rates of 2.24 or 3.36 kg/ha under field and ...
Migration patterns and returns to migration among female-headed families
(1990)
The main goal of this dissertation was to study migration patterns and socioeconomic returns to migration among migrant female-headed families. The Texas data used in the dissertation were drawn from public-use microdata ...
