Propionyl holocarboxylase synthesis
(Virginia Polytechnic Institute, 1963)
A soluble enzyme system, isolated from livers of biotin-deficient rats, catalyzes the ATP-dependent synthesis of propionyl holocarboxylase from d-biotin and propionyl apocarboxylase. This system has been resolved by alumina ...
Design of an experiment to investigate superheat effect on gate velocities
(Virginia Polytechnic Institute, 1963)
The objective of this thesis investigation was to design an experiment to investigate superheat effect on gate velocities pressurized and unpressurized gating system each having two gates, and to analyze statistically any ...
Some factors that influence the election of homemaking in secondary schools in Montgomery County, Virginia
(Virginia Polytechnic Institute, 1964)
This investigation was made to determine some of the factors that influence the election of homemaking in secondary schools; and, to determine the bases used by guidance counselors when assisting high school girls with the ...
The robustness to non-normality of significance levels of the t and F tests
(Virginia Polytechnic Institute, 1965)
A statistical test is called"robust" if it is insensitive to departures from the underlying assumptions, this term was introduced by Box (4).
Theoretical study made by Gayen (13), (14) and (15) showed that"Student's" ...
Study of a microbial commensalism
(Virginia Polytechnic Institute, 1965)
Saccharomyces cerevisiae V. P. I. Strain No. 1 was found to estimate the growth of Proteus vulgaris V. P. I. Strain No. 3 in a chemically-defined medium when growth curves of the viable counts of the two organisms in pure ...
A utilization study of programmed shorthand
(Virginia Polytechnic Institute, 1965)
PURPOSE: The purposes of this study were (1) to try out a shorthand theory program in a high school first-year shorthand class to determine if it could be used successfully in place of a textbook; (2) to determine whether ...
Prediction of soil moisture from selected climatic data
(Virginia Polytechnic Institute, 1966)
Climatic variables have been used to calculate evapotranspiration loss by many researchers. Evapotranspiration formulas have been developed for local use in predicting soil moisture in many parts of the United States. The ...
A survey of a selected number of state homemaker degree recipients of the Virginia association, Future Homemakers of America, 1949-1958
(Virginia Polytechnic Institute, 1965)
This study was made to discover how high school homemaking had helped Sate Homemaker degree recipients in their own homemaking. Data were compiled from 109 State Homemaker degree recipients who were awarded the degree from ...
The directional stability and control of an airplane during the landing roll
(Virginia Polytechnic Institute, 1967)
This thesis considers the problem of the directional instability, as exhibited by aircraft with tricycle landing gear, during the landing roll after touchdown. The approximate equations of motion are solved on an analog ...
Statistical study of measurements of nematodes
(Virginia Polytechnic Institute, 1964)
This thesis is a preliminary statistical study on two nematodes, Horsenettle Cyst and Osborne Cyst. Each of the two nematodes were collected from two hosts, Horsenettle weed and tobacco. For each of the four combinations ...
