Radiotracer methodology in biological science

Creator:: Willis, David L.
Abstract:: The use of radioactive isotopes as tracers in biological systems has become widespread since the close of World War II. Proper use of radiotracers requires a fundamental understanding of the physical nature of radioactivity, the characteristics of ionizing radiation, and the various methods available for measuring radioactivity. More importantly, the...

Physiology, quality, and agronomic performance of snap beans (Phaseolus vulgaris L.) and spring wheat (Triticum aestivum L.) as affected by environment and several plant growth regulators

Creator:: Hile, Mahlon Malcolm Schallig
Abstract:: Experiments were conducted to determine the effect of environment and several plant growth regulators on the physiology, quality, and agronomic performance of snap beans (Phaseolus vulgaris L. ) and spring wheat (Triticum aestivum L. ). The potassium salts of naphthenic acid and cyclohexanecarboxylic acid, received particular attention. Application of potassium...

The influence of vocationally-oriented applications on the achievement and attitude of community college algebra students

Creator:: Morgan, Micheal E.
Abstract:: The purpose of this study was to analyze the effect of the use of vocationally - oriented applications on the achievement and attitude of community college beginning algebra students. The applications were chosen to be representative of problems encountered in a variety of occupations. They were in contrast to the...

Sneakerheads’ Assessment of Sneaker Value and Behaviors throughout the Sneaker Ownership Cycle

Creator:: Choi, JIn Woo
Abstract:: The purpose of the present study was to investigate value perceptions and consumption behaviors of sneakerheads who are mixed-role resellers of sneakers. “Sneakerhead” is a term given to those who collect and wear sneakers with a vast amount of effort and resources (Semmelhack, Garcia, Lepri, Willis, & Hatfield, 2015). “Mixed-role...

Water and solute transport : modeling and application to water conservation in layered soil

Creator:: Mohammed, Fareed H. A. N.
Abstract:: Sandy soils are among the least productive soils because of their inability to store adequate water for plant growth. Their high percolation rate not only allows water to move quickly beyond the root zone, but also washes nutrients below the reach of plant roots. High evaporation occurs from the soil...

Detecting fluid flows with bioinspired hair sensors

Creator:: Dickinson, Benjamin T.
Abstract:: Many animals detect prey or enhance their locomotion with information from hair-like receptors that are activated by local fluid flows. The utility of biological hair receptors has motivated the design of artificial hair sensors (AHS) for flow control applications where aerodynamic or hydrodynamic forces play a significant role in the...

Charles Babbage, philosopher, reformer, inventor : a history of his contributions to science

Creator:: Bell, Walter Lyle
Abstract:: This history concerns the scientific contributions of Charles Babbage (1791-1871) to mathematics, to the invention of calculating machines, and machine tools, to the development of scientific ideas through a wide variety of scientific investigations and his involvement in several different scientific reforms. Babbage considered himself a philosopher in the broadest...

The Association Between Extreme Climate and Diarrheal Illness in North America

Creator:: Lyon-Colbert, Amber
Abstract:: The etiology and transmission of bacterial diarrheal pathogens is complex, making evaluating the association between extreme climate and diarrheal illnesses in North America challenging. Changes in climate may impact the survival, reproduction, and distribution of pathogens that cause diarrheal illness. Evidence supports the hypothesis that reproduction, survival, and transmission ability...

The effect of winter grazing on production and dynamics of a Lolium perenne (L.)-Trifolium repens (L.) pasture

Creator:: Jaindl, Raymond G.
Abstract:: Perennial ryegrass (Lolium perenne) - white clover (Trifolium repens) hill-land pastures were grazed at different times in the winter to study the effect of time of winter grazing on plant response and forage production. The same pastures were grazed by sheep once in early December, January, February, March, or April...

Frequency-domain, parameter estimation for a brushless, doubly-fed machine

Creator:: Ramchandran, Ashok
Abstract:: A Brushless, Doubly Fed Machine (BDFM) attempts to combine the advantages of conventional induction and synchronous types of electrical machines by its unique architecture. The validation of BDFM designs in an actual test environment requires the estimation of the BDFM model parameters from actual experimentation. Accurate values for the parameters...
