Mitochondrial Dna Genome Sequencing And Snp Assay Development For Increased Power Of Discrimination, Thomas J. Parsons
Mitochondrial Dna Genome Sequencing And Snp Assay Development For Increased Power Of Discrimination, Thomas J. Parsons
US Army Research
This report details the work performed over a period of five years in an NIJ-funded project intended primarily to develop a practical means for accessing the large reserve of genetic variation in the ~15,000 bp mtDNA coding region, as a means for augmenting the forensic discrimination provided by sequencing the hypervariable (HV) regions of the mtDNA control region. Our approach was to focus on the relatively small number of particularly common types present in US Caucasian, African American, and Hispanic populations, where the problem of limited discrimination is concentrated in practice. We sequenced 506 entire mtDNA genomes corresponding to 56 …
Identity And Distribution Of Residues Of Energetic Compounds At Army Live-Fire Training Ranges, Thomas F. Jenkins, Alan D. Hewitt, Clarence L. Grant, Sonia Thiboutot, Guy Ampleman, Marianne E. Walsh, Thomas A. Ranney, Charles A. Ramsey, Antonio J. Palazzo, Judith C. Pennington

Environmental investigations have been conducted at 23 military firing ranges in the United States and Canada. The specific training facilities most frequently evaluated were hand grenade, antitank rocket, and artillery ranges. Energetic compounds (explosives and propellants) were determined and linked to the type of munition used and the major mechanisms of deposition.
The Dielectric Behavior Of Polycrystalline Ferroelectric Films With Fiber Textures, Quangen Du, Jiangyu Li, William Nothwang, Melanie W. Cole
The Dielectric Behavior Of Polycrystalline Ferroelectric Films With Fiber Textures, Quangen Du, Jiangyu Li, William Nothwang, Melanie W. Cole
US Army Research
We consider the effects of crystallographic symmetry, texture, and internal strain on the dielectric properties of polycrystalline ferroelectric thin films with fiber textures, including spontaneous polarization, coercivity, dielectric constant, dielectric tunability, and strain-induced phase transition, by combining Landau–Ginzburg–Devonshire phenomenological theory for ferroelectrics with the micromechanics theory for polycrystalline thin films. Cubic and tetragonal BaxSr1_xTiO3 (BST) films with [001] fiber texture, and cubic and rhombohedral BST films with [111] texture are considered. The results show that for [001]-textured film compressive strain enhances the spontaneous polarization, coercivity, and tunability while it decreases the dielectric constant; for [111]-textured film the effects are the …
Evolution Of The Snow Area Index Of The Subarctic Snowpack In Central Alaska Over A Whole Season. Consequences For The Air To Snow Transfer Of Pollutants, A.S. Taillandier, F. Domine, W.R. Simpson, M. Sturm, T.A. Douglas, K Severin
Evolution Of The Snow Area Index Of The Subarctic Snowpack In Central Alaska Over A Whole Season. Consequences For The Air To Snow Transfer Of Pollutants, A.S. Taillandier, F. Domine, W.R. Simpson, M. Sturm, T.A. Douglas, K Severin
US Army Research
The detailed physical characteristics of the subarctic snowpack must be known to quantify the exchange of adsorbed pollutants between the atmosphere and the snow cover. For the first time, the combined evolutions of specific surface area (SSA), snow stratigraphy, temperature, and density were monitored throughout winter in central Alaska. We define the snow area index (SAI) as the vertically integrated surface area of snow crystals, and this variable is used to quantify pollutants’ adsorption. Intense metamorphism generated by strong temperature gradients formed a thick depth hoar layer with low SSA (90 cm2 g-1) and density (200 kg …
Effects, Transfer, And Fate Of Rdx From Aged Soil In Plants And Worms, E.P.H. Best, K.N. Geter, H.E. Tatem, B.K. Lane
Effects, Transfer, And Fate Of Rdx From Aged Soil In Plants And Worms, E.P.H. Best, K.N. Geter, H.E. Tatem, B.K. Lane
US Army Research
The objectives of this study were to provide data that can be used to predict exposure-based effects of RDX in aged soil on multiple endpoint organisms representing two trophic levels. These data can be used for defining criteria or reference values for environmental management and conducting specific risk assessment. Dose–response experiments formed the basis for the evaluation of toxic effects and transfer of contaminants from soil into two trophic levels. Long-term exposure tests were conducted to evaluate chronic, sublethal, toxicity and transfer of aged soil-based explosives, with RDX as main contaminant. In these tests, plants were exposed for 55 days …
Proposed Evaluation Of Switchgrass Selections For Caddo House Construction, Charles Allen, Sara Thames, Jim Grafton, Bill Welton, Lorene Williams, Katina Mcclure, Darryl Monteau, Phil Cross, Andrew Hamblin, William Meyer
Proposed Evaluation Of Switchgrass Selections For Caddo House Construction, Charles Allen, Sara Thames, Jim Grafton, Bill Welton, Lorene Williams, Katina Mcclure, Darryl Monteau, Phil Cross, Andrew Hamblin, William Meyer
US Army Research
The Caddo Indian tribe’s range was northwest Louisiana, northeast Texas, eastern Oklahoma, western Arkansas, and southwest Missouri. Historical records indicate the use of native switchgrass (Panicum virgatum) in the construction of houses. The frame and stringers for the houses were wood but the entire covering was bundles of switchgrass. In 2005, Fort Polk personnel and faculty and students at Haskell Indian Nations University in Lawrence, Kansas initiated a joint monitoring effort of biological (density, height, seed production), cultural, and other characteristics of switchgrass. Both groups have ongoing field and greenhouse plots with selections of switchgrass from throughout the …
