Alert Systems for Missing Adults in Eleven States: Background and Issues for Congress (open access)

Alert Systems for Missing Adults in Eleven States: Background and Issues for Congress

This report discusses the emerging development of nationwide alert systems to recover missing adults, such as those with mental impairment (such as Alzheimer's disease), developmental disabilities, or suicidal tendencies. This report provides an overview of such alert systems in 11 states: Colorado, Delaware, Florida, Georgia, Kentucky, North Carolina, Ohio, Oklahoma, Rhode Island, Texas, and Virginia. This report also provides a discussion of issues for Congress to consider with respect to the federal role, if any, in developing state alert programs for missing adults.

Combined Geophysical Investigation Techniques to Identify Buried Waste in an Uncontrolled Landfill at the Paducah Gaseous Diffusion Plant, Kentucky (open access)

Combined Geophysical Investigation Techniques to Identify Buried Waste in an Uncontrolled Landfill at the Paducah Gaseous Diffusion Plant, Kentucky

The primary objective of the investigation was to confirm the presence and determine the location of a cache of 30 to 60 buried 55-gallon drums that were allegedly dumped along the course of the pre-existing, northsouth diversion ditch (NSDD) adjacent to permitted landfills at the Paducah Gaseous Diffusion Plant, Kentucky. The ditch had been rerouted and was being filled and re-graded at the time of the alleged dumping. Historic information and interviews with individuals associated with alleged dumping activities indicated that the drums were dumped prior to the addition of other fill materials. In addition, materials alleged to have been dumped in the ditch, such as buried roofing materials, roof flashing, metal pins, tar substances, fly ash, and concrete rubble complicated data interpretation. Some clean fill materials have been placed over the site and graded. This is an environment that is extremely complicated in terms of past waste dumping activities, construction practices and miscellaneous landfill operations. The combination of site knowledge gained from interviews and research of existing site maps, variable frequency EM data, classical total magnetic field data and optimized GPR lead to success where a simpler less focused approach by other investigators using EM-31 and EM-61 electromagnetic methods …

Oral History Interview with Edward Nielsen, August 23, 2001 (open access)

Oral History Interview with Edward Nielsen, August 23, 2001

The National Museum of the Pacific War presents an oral interview with Edward Nielsen from Medaryville, Indiana. He discusses undergoing Amry training at Fort Knox, Kentucky, before being assigned as B Company of the 69th Army Regiment at Fort Knox as a private. Afterwards he got lucky and was assigned to drive a truck from Louisiana to North Carolina, Mr. Nielsen describes this as the best job he ever had in the Army. After Pearl Harbor he is transferred to the 1st Armored Division and Regiment, 2nd Battalion. He was then transported from fort Knox to Ireland then to England for a short time before being shipped out to Oran in North Africa. On the way to Oran, the ship he was on was almost hit by a missile shot by a German U-boat, but it instead hit another ship that was nearby. By the time Mr. Nielsen reached Oran he was a segreant Tank Commander. He also relays a time he warned his Company Commander about German Tiger Tanks being in their area and being ignored only for them to show up a few days later resulting in one captain deserting and being captured by German soldiers. Mr. Nielsen …

Analysis of Devonian Black Shales in Kentucky for Potential Carbon Dioxide Sequestration and Enhanced Natural Gas Production Quarterly Report: April-July 2004 (open access)

Analysis of Devonian Black Shales in Kentucky for Potential Carbon Dioxide Sequestration and Enhanced Natural Gas Production Quarterly Report: April-July 2004

Devonian gas shales underlie approximately two-thirds of Kentucky. In the shale, natural gas is adsorbed on clay and kerogen surfaces. This is analogous to methane storage in coal beds, where CO{sub 2} is preferentially adsorbed, displacing methane. Black shales may similarly desorb methane in the presence of CO{sub 2}. Drill cuttings from the Kentucky Geological Survey Well Sample and Core Library are being sampled to collect CO{sub 2} adsorption isotherms. Sidewall core samples have been acquired to investigate CO{sub 2} displacement of methane. An elemental capture spectroscopy log has been acquired to investigate possible correlations between adsorption capacity and mineralogy. Average random vitrinite reflectance data range from 0.78 to 1.59 (upper oil to wet gas and condensate hydrocarbon maturity range). Total organic content determined from acid-washed samples ranges from 0.69 to 4.62 percent. CO{sub 2} adsorption capacities at 400 psi range from a low of 19 scf/ton in less organic-rich zones to more than 86 scf/ton in the Lower Huron Member of the shale. Initial estimates based on these data indicate a sequestration capacity of 5.3 billion tons of CO{sub 2} in the Lower Huron Member of the Ohio Shale of eastern Kentucky and as much as 28 billion tons …

Analysis of Devonian Black Shales in Kentucky for Potential Carbon Dioxide Sequestration and Enhanced Natural Gas Production Quarterly Report: April-June 2003 (open access)

Analysis of Devonian Black Shales in Kentucky for Potential Carbon Dioxide Sequestration and Enhanced Natural Gas Production Quarterly Report: April-June 2003

CO{sub 2} emissions from the combustion of fossil fuels have been linked to global climate change. Proposed carbon management technologies include geologic sequestration of CO{sub 2}. A possible, but untested, sequestration strategy is to inject CO{sub 2} into organic-rich shales. Devonian black shales underlie approximately two-thirds of Kentucky and are thicker and deeper in the Illinois and Appalachian Basin portions of Kentucky than in central Kentucky. The Devonian black shales serve as both the source and trap for large quantities of natural gas; total gas in place for the shales in Kentucky is estimated to be between 63 and 112 trillion cubic feet. Most of this natural gas is adsorbed on clay and kerogen surfaces, analogous to methane storage in coal beds. In coals, it has been demonstrated that CO{sub 2} is preferentially adsorbed, displacing methane. Black shales may similarly desorb methane in the presence of CO{sub 2}. The concept that black, organic-rich Devonian shales could serve as a significant geologic sink for CO{sub 2} is the subject of current research. To accomplish this investigation, drill cuttings and cores were selected from the Kentucky Geological Survey Well Sample and Core Library. Methane and carbon dioxide adsorption analyses are being performed …
