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...

Supervisory control and data acquisition (SCADA) systems are used by many critical infrastructures including electric power production and distribution, water and waste water treatment, rail transportation, and gas and oil distribution. Originally...
This dissertation deals with various imidazole compounds with emphasis on hydrogen bond interactions and weaker intermolecular forces. New amide functionalized polyimidazole metal binding pockets are able to form intramolecular six-membered...
Heat pipes; Solar heating--Passive systems; Solar heating--Research; Solar energy--Research
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...
Water treatment facilities strive to provide potable drinking water to the community which they service. The most common way of insuring drinkable water that is free of pathogens is water chlorination, but this can lead to the production of...
Rising environmental concerns due to our rising population ad energy demand along with our excessive dependence on fossil fuels has created an urgent need to find clean, renewable and carbon free source of energy. Photoelectrochemical (PEC) water...
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...
Atmospheric nitrous oxide; Nitric acid; Rain and rainfall--Environmental aspects
Having been born and brought up in China, an empire, where the people are utterly ignorant of the vital importance of a good system of public water supply, and having decided to take chemistry as my profession, I feel intensely interested in the...
In 2003, Wilson Creek running through Bernheim Arboretum and Research Forest in central Kentucky was restored to its original winding path through a valley field. Early 20th century settlers had previously redirected this creek to run a straight...
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...
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...
The use of monochloramines in the potable water supply industry has been selected as the disinfectant method of choice due to a longer term of effectiveness and less toxic by-products than the previous choice of chlorine. In spite of the benefits...
In this work, micro fabrication techniques are explored not only to simplify the production of complex lab on-a-chip devices (LOC), but also micro fabrication will be utilized to create intelligent design features that will enhance an...
Hematite synthesized by low pressure oxygen plasma has been shown previously to exhibit promising characteristics as a photo-anode for a photoelectrochemical water splitting cell. It is cheap, stable and has a 2.1 eV bandgap and exhibits a...
Iron oxide, Fe2O3, is a promising material for water splitting reaction using solar
energy due to its stability and optimal bandgap of 2 eV. Even the recent efforts, however,
using Fe2O3 thin film materials reported low efficiencies due to poor...
Human exposure to mercury has been shown to cause a number of adverse health outcomes, predominantly neurological effects. The developing fetus is most susceptible, and even low levels of exposure have been shown to produce nervous system deficits....
The purpose of the research is to assess the emergency communication messages that water and wastewater utilities used to correspond with the public during a crisis event. This assessment includes a review of data and disseminated messages provided...
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...
Aquatic ecosystems face major transformations as humans increasingly alter their environment by introducing exotic species and changing the temperature regime and nutrient availability of freshwater systems. The impacts of such alterations of...
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...
