The Knudsen pump works on the principle of thermal transpiration. As a result of requiring a thermal gradient, channel hydraulic diameter smaller than the mean free path of the gas being pumped, and having no moving parts, the Knudsen pump features...
Missing data is very common in survey research. However, currently few guidelines exist with regard to the diagnosis and remedy to missing data in survey research. The goal of this thesis was to investigate properties and effects of three selected...
The thesis focuses on improving the flowrate of the Knudsen gas pump. The Knudsen pump uses thermal transpiration as the driving mechanism to pump gas. It is a motionless gas pump as the pump does not require any moving actuators for pumping. The...

Teenaged workers are twice as likely to be injured on the job as adult workers, and face a
number of differences developmentally and psychosocially that present challenges for
their safety at work. Little research has focused on the tasks that...
In this dissertation, standardized methods for measuring electron emission (EE) from nanostructured materials are established. Design of an emitter array platform, synthesis and nanomanipulation of different types of are successfully conducted....
In July 1995, National Science Foundation Award # 9551869 funded the development of a new inter-disciplinary microfabrication course under the primary leadership of Dr. Kevin Walsh at the University of Louisville. Along with this award, the...
Contamination can be very difficult to remove from water. Once this water seeps into the ground, the difficulty grows exponentially. The Paducah Gaseous Diffusion Plant, located in Paducah, Kentucky, has contaminated the groundwater. The...
The future of renewable energy technologies involves overcoming difficulties
with the creation of new materials. The use of nanotechnology has allowed for
inexpensive materials to achieve very interesting physical and electronic properties....
CDCIWHO only "recommends" that rings be removed under gloves because of cross-contamination between health care workers and patients. Microbiological samples of oral streptococci beneath rings and between fingers under non-sterile exam...

Lithographic processes for printing device structures on integrated circuits plays a major role in the semiconductor industry. This project aims at designing and fabricating a programmable mask for a direct write lithography system which can...
The Louisville Leader was an African-American newspaper published from 1917 to 1950 by I. Willis Cole in Louisville, Kentucky. This issue says Vol. 32. No. 29. but is actually Vol. 33. No. 36. There is a whole in the top half of pages one and two...
A novel catalyst with hydro-desulfurization and hydrogenation capabilities was tested with the aim of producing ultra-low sulfur and aromatics diesel oil. The catalytically active phase is nickel in a reduced valence state on a carrier made of zinc...
The oxidation of metallothiolates is complicated by "non-innocence" or potential
redox activity of sulfur to yield thiyl (RS•) radicals. In some instances, the one-electron
oxidation of metal thiolates yields a product with the unpaired...
Acridine is a compound that has a ring system similar to anthracene except that one of the CH groups is replaced by a -N- group. It is possible for this compound to have desmotropic forms as those that follow. When an amino group is present in the...
The role of mothers, the constitution of families, and the power of their stories are the bedrock of my thesis, which is the first 90 pages of a novel entitled Playing House . In it, I hope to investigate the denotation and connotation of the words...
The Louisville Leader was an African-American newspaper published from 1917 to 1950 by I. Willis Cole in Louisville, Kentucky. This issue says Vol. 32. No. 22. but is actually Vol. 33. No. 29. There are holes in the center of each page and portions...
The Louisville Leader was an African-American newspaper published from 1917 to 1950 by I. Willis Cole in Louisville, Kentucky. This issue says Vol. 32. No. 26. but is actually Vol. 33. No. 33. There are holes in the center of each page of this...
This dissertation describes new procedures for synthesizing and purifying Au and Au/Ag nanoplates directly on surfaces as well as controlled binding of proteins to their surface. It also describes fundamental changes in the optical properties of Au...
The research in this dissertation describes a simple electrochemical approach for fabricating nanoscale (metal/metal) or molecular (metal/polymer or self assembled monolayer (SAM)/metal) junctions. The fabrication involves metal deposition on one...
Acridine was discovered by Graebe and Caro who found that it accompanied the crude
anthracene obtained from coal-tar. For its isolation, the portion of the tar distilling at 300°- 360° C. was extracted by dilute sulphuric acid and precipitated by...
