Paleonutrition of the Lower Pecos Region of the Chihuahuan Desert
(1991)
Paleonutritional analyses require an integration of dietary disciplines to determine both the diet of a prehistoric population and the subsequent nutritional intake. Under optimal conditions, the zooarchaeology, paleoethnobotany, ...
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 ...
Performance characterization of monolithic thin film resistors
(1992)
Thin film resistors have a large resistance range and stable performance under high temperature operating condition. Thin film resistors trimmed by laser beam are able to achieve very high precision on resistance value. ...
Genetic and molecular basis for the specificity of the RTX toxins from Pasteurella haemolytica and Actinobacillus pleuropneumoniae
(1992)
The leukotoxin (LktA) from Pasteurella haemolytica and the hemolysin (AppA) from Actinobacillus pleuropneumoniae are members of a highly conserved family of cytolytic proteins produced by gram negative bacteria. Their ...
Relationships among the test of English as a foreign language, the English language placement test, and the academic performance of undergraduate non-native English speaking students at Texas A & M University
(1992)
The problem was to investigate relationships between the proficiency tests administered to beginning international students, and GPA to find which, if any, were useful in determining readiness for academic study. This study ...
The working models of attachment theory : qualitative characteristics and generalizability across relationships
(1992)
This study investigates characteristics of the working models of attachment theory. Working models are the cognitive-affective concomitants of the attachment styles (secure, anxious/ambivalent, and avoidant) proposed by ...
Forecasting critical tasks for community education as perceived by state community education association presidents
(1992)
This is a national study of critical tasks facing community education. These critical tasks were generated by Presidents of State Community Education Associations and represent their perceptions of the critical tasks facing ...
Syntheses of linear tetrapyrroles as potential inhibitors for uroporphyrinogen III synthase
(1992)
Living systems depend on a variety of metal complexes of tetrapyrrolic macrocycles to carry out many biologically important functions. Among these pigments of life are heme, chlorophyll and vitamin B[12]- All these substances ...
Serum and milk mineral concentration and milk yield of beef cows of three breed types
(1992)
Sixteen Hereford x Holstein (HH), 25 Hereford x Jersey and 27 Hereford (H) cows 7 to 12 yr of age grazed native and improved pastures as a single group in two experiments. Cows were mated to one of two Charolais bulls over ...
