National development continuum : a test of the Harbison-Myers Human Resource Development Index
(1989)
The purpose of the study was to determine whether or not the Harbison-Myers Human Resource Development Index (HRDI) method of ranking, classifying and comparing countries supported the idea of a continuum of national ...
An empirical comparison of univariate and multivariate repeated measures analysis techniques when applied to motor performance data : a Monte Carlo study
(1989)
The purpose of this study was to examine, through Monte Carlo methods, the empirical alpha levels and the statistical power obtained when selected data from motor learning research was subjected to univariate and multivariate ...
Biochemical site(s) of growth inhibition in Phymatotrichum omnivorum and Pythium ultimum by triazoles [fungicides]
(1989)
Comparative tests were conducted on Phymatotrichum omnivorum (Shear) Duggar and Pythium ultimum (Trow) to determine if an alternative mode of action exists for two different triazole fungicides. The accepted mode of action ...
Chemical and functional properties of glandless cottonseed protein
(1989)
Glandless cottonseed protein isolates (CPI-I and II) were prepared using gel filtration chromatography. They contained large amounts of glutamic acid, arginine, and aspartic acid and had minimum solubilities at pH 4 and ...
Static vs. dynamic visuals in computer assisted instruction
(1989)
A literature review revealed that spatial abilities (visualization and relation) may be developed by creating an internal schema by which a student may be able to manipulate two-dimensional images of objects into ...
The effects of mathematically non-threatening science courses on attitudes, career choice and continued science education
(1989)
The purpose of this study was to determine if the effects of taking a third year, mathematically non-threatening science course would increase participation of selected groups of students in the further selection of ...
Variation in virulence of Colletotrichum graminicola (Ces.) Wils. and competition between monoconidial isolates
(1989)
Single spore isolates of Colletotrichum graminicola were taken from sorghum or johnsongrass in agricultural, research station and natural populations and compared on a series of sorghum differential varieties in the ...
Tilt pad bearing effects on rotordynamic stability and improvements in global system dynamic analysis
(1989)
A general method of incorporating pad flexibility effects into isothermal tilting pad bearing analysis is developed. The pad assembly approach is extended using two-dimensional finite elements to determine pad deformations ...
Species replacement in response to herbivory : influence of grazing history, competitive interactions and population structure
(1989)
Although the concept of range condition classification has served as a basic tenant of range management in the United States for nearly 40 years, the mechanisms associated with species replacement have received remarkably ...
Role of ecdysteroids in the molting and reproductive cycles of the white shrimp, Penaeus vannamei
(1989)
The molt cycle was characterized in the white shrimp Penaeus vannamei based upon changes in the morphology of pleopod setae. These characters were used subsequently to determine changes in ecdysteroids and related biosynthetic ...
