Channel modification has played a vital part in shaping the rivers and streams as
they are seen today. Channel modifications range from the construction of dams and levees
for flood control purposes to channelization of an existing meandering...
Within the Appalachian hills of eastern Kentucky, large-scale coal mining operations are directly altering the headwater landscape through the construction of hollow fills. These man-made landforms and their associated in-stream structures alter a...
For complex classification systems, data is usually gathered from multiple sources of information that have varying degree of reliability. In fact, assuming that the different sources have the same relevance in describing all the data might lead to...
This thesis looks at the optimization of fluid flow and mass transfer using computational fluid dynamics (CFD) in a micro fluidic coulter counter. CFD will be used to solve equations of fluid flow and mass transfer to see how molecules within the...
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...
This work develops a method of estimating peak daily streamflow, Qpeak, for Kentucky streams using daily average streamflow, Qave, data from the United States Geological Survey's (USGS) National Water Information System (NWIS) website. The purpose...
Surface active agents; Rendering industry--Waste disposal; Air filters
Meat is a major component of the diet of an American. However, humans do not consume one-third to one-half of each animal raised for their needs. The leftover materials are subjected to processing in the meat rendering industry. The rendering...
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...
Enzymatic hydrolysis is the most common method of producing fermentable sugars from lignocellulosic biomass. Limitations to this step include the high cost of enzymes, and the time required to process the biomass. To increase the throughput and...
The revolution in information technology and the explosion in the use of computing devices in people's everyday activities has forever changed the perspective of the data mining and machine learning fields. The enormous amounts of easily...
Electronic commerce--Corrupt practices--Prevention; Internet advertising--Corrupt practices; Internet fraud
Online search advertising is currently the greatest source of revenue for many Internet giants such as Google™, Yahoo!™, and Bing™. The increased number of specialized websites and modern profiling techniques have all contributed to an...
Wind power has the potential to provide access to electricity to areas lacking the resources to create industrial power plants, as well as supplement residential energy supplies. The low resource investment and ease of installation make it ideal...
Draw A Secret password systems have recently come into vogue, primarily in the role of protecting a user’s cellular smart phone from external infiltration in lieu of a password. However, these password systems are only enabled for single touch...
High solids processing of biomass slurries provides the following benefits: maximized product concentration in the fermentable sugar stream, reduced water usage, and reduced reactor size. However, high solids processing poses mixing and heat...
Nosocomial infections; Catheterization--Complications; Drug resistance in microorganisms
Catheters represent an essential part of the management of critically and chronically ill patients. However, their use is often plagued by catheter related blood stream infections (CRBSIs), which are associated with increased morbidity, hospital...
Enzymatic hydrolysis is an important, but time limiting step in the process of converting biomass into ethanol. High solids concentrations are desired in order to minimize reactor size and achieve a higher concentration of glucose in the end...
A woman holds her horse steady in a stream. Her riding outfit includes a hat, jacket, blouse, and wide-hipped pants tucked into knee-high boots. The dark horse has bridle with a bit. The saddle rests on top of a blanket and the rider's boots rest...
A woman in a cap, jacket, and riding boots pauses on a horse. She is likely Mary Breckinridge, founder of the Frontier Nursing Service. The horse wears a bridle and a saddle with a blanket. The scene is set in a stream with woods and a building in...
A dark horse with a white mark on its forehead stands in water a couple of feet deep. The water appears to be a stream due to its depth and the view of land on one side with a branch extending out over the water. A rider sits on top of the horse,...
