An investigation was made into the relative costs of excavation retention by two systems: conventional soldier pile-wale-tieback support, and support by soil nailing. The investigation included design of excavation supports by the two...
The following thesis examines the relationship between site geology and ground motion amplification for medium sized earthquake events in the Ohio Valley area. This thesis also includes a Rapid Screening Guide that can be used to estimate...
Archaeologists use soil analysis to detect chemicals, like phosphate, to indicate areas of anthropogenic activity. Phosphate detection is a multi-step process, which makes standard techniques time consuming. Kinetic studies decreased the analysis...
Ten algal isolates were obtained from soil into axenic culture and placed into defined media containing from 0 to 50 ppm of DDT, 2, 4-D,2,4,5-T, rotenone, or malathion (in two purities, 95 and 99%). For nine of the isolates, growth was measured...
Stream riparian zones are ecotones between terrestrial and aquatic environments. Studying these areas in urban environments is important since they lie adjacent to stream water supplies. I conducted a study of riparian woody and groundcover...
A potential source of fine grained suspended sediments in a stream system is the
upper hillslopes of the drainage. Quantifying the sediment produced and transported to a
stream from these hillslopes is challenging because of the complex nature of...
Urbanization disrupts natural soil profiles and as watersheds are
urbanized, their surfaces become impervious and this will result in
reduction of infiltration. For this reason, many cities are facing problems
with treating runoff water. Best...
Soon after the atomic theory was established, it was found that the plant uses as sources of food not only the air and water, but also different constituents of the soil, dissolved in the soil moisture—the mineral nutrients. Ashes of different...
Gardeners--Kentucky--Louisville--Social conditions; Community gardens--Kentucky--Louisville
Using four surveys, two created by this researcher, another created by Walizcek, Mattson, and Zajicek, and a fourth created by Herbach, the researcher compared the characteristics of community gardeners, their motivations for gardening, and the...
Pattern recognition systems; Land mines--Detection; Pattern perception--Data processing; Data mining
Traditional machine learning and pattern recognition systems use a feature descriptor to describe the sensor data and a particular classifier (also called "expert" or "learner") to determine the true class of a given pattern....
A quarter of a century ago, Abraham Epworth Rounds, aged forty-five, came shambling out of mountainous Eastern Tennessee to one of our Kentucky cities. He was intent on making a living in easier fashion than scratching it from the lean soil of the...
All terrain vehicles--Automatic control; Motor vehicles--Automatic control; Intelligent control systems
When tracked vehicles traverse terrain such as sand, soil, or even concrete,
they may encounter a variance in density or viscosity of the medium that the
vehicle is traveling along. When this happens, one track begins to move faster or
slower...
View from above of a valley in Scotland with a river snaking through it. Fields and trees are on either side of the valley. A tree branch juts out from the left near the top. A young man stands overlooking the valley. Title: 2626 - The Valley of...

"Though its exact date is unknown, the nature of the brushwork and general intensity of style suggest late 1888 or early 1889 while van Gogh was still in Arles, the village in Provence [...]. It may even have been executed after van Gogh...
From Hierakonpolis, Egypt. "In Predynastic times, Egypt was divided geographically and politically into Upper Egypt (the southern, upstream part of the Nile Valley), a narrow tract of grassland that encouraged hunting, and Lower (northern)...
