The one dimensional heat transfer, thermal diode effect of heat pipes makes
them ideal for passive solar applications. Gains in a heat pipe passive solar wall are not
lost during cloud cover or periods of low irradiation. An experimental model was...
The heat pipe augmented solar wall operates much more efficiently for domestic air heating than alternative passive solar technologies. The thermal diode effect of heat pipes reduces the insulating losses of the unit during nighttime and adverse...
A significant amount of effort has been put in developing tools to interpret Ground Penetrating Radar signals obtained during surveys. Currently, skilled and experienced users do most of GPR image interpretation. They use experience in deciphering...
Supervisory Control and Data Acquisition (SCADA) systems are used in almost
all industrial processes including use in the nation's critical infrastructure. The electric,
water, and gas industries are merely a few that rely heavily on the use of...
The Louisville Leader was an African-American newspaper published from 1917 to 1950 by I. Willis Cole in Louisville, Kentucky. This issue is four pages and there is a crease across the center of pages one and two that make some portions illegible.

Hind limb paralysis may occur in dogs for a variety of neurological or musculoskeletal reasons. For dogs with limited mobility their lack of ability to ambulate can have a great impact on their physical and mental health. Canine wheelchairs can...
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...
Nitrile hydratase (NHase) is a metalloenzyme that contains a non-heme iron (III)
or non-corin cobalt (III) in a non-redox active role. NHase is used as biocatalyst in the
industry for the hydrolysis of nitriles to arnides. The trivalent metal ions...
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...
