Potential Chemicals To Manage Llght Goose Populations, John Cummings, Pete Poulos

United States Department of Agriculture Wildlife Services: Staff Publications

Over-abundant light geese are having long-term negative effects on the Arctic tundra ecosystem. Significant damage to native plants, increases in soil degradation and impacts on bird communities are likely to be the main consequences (Batt 1998). The extent of which over-abundant light geese reduce food and cover for other wildlife on wintering grounds and migration routes is not well documented, although anecdotal observations suggest that light geese could compete with wintering waterfowl for food, i.e. Louisiana rice fields (J. L. Curnmings, National Wildlife Research Center, personal observation).

Oral Rabies Vaccination: Reducing Economic Uncertainty Via Response Surface Analysis, Ray T. Sterner, Matthew A. Kling, Stephanie A. Shwiff, Dennis Slate

United States Department of Agriculture Wildlife Services: Staff Publications

Economic uncertainty surrounds the distribution of Raboral V-RG7 as an oral rabies vaccine (ORV) bait for the containment or elimination of raccoon-variant rabies in the United States. This paper describes a costs-savings model of ORV. It also describes Excel XP7 code that was prepared to compute potential net savings (NS) and benefit-cost ratios (BCRs) associated with Raboral V-RG7 bait distributions. Currently, baits and bait distributions are relatively expensive; individual baits are produced at a cost of $1.27 for federal use and typically dispensed at >75 baits/km2. Distribution is estimated at $8.62/km², $15.80/km², and $33.30/km² for …

Double-Crested Cormorant Impacts To Commercial And Natural Resources, Jimmy D. Taylor Ii, Brian S. Dorr

United States Department of Agriculture Wildlife Services: Staff Publications

The North American population of double-crested cormorants (Phalacrocorax auritus) has increased at an annual rate of 6.8% since 1966, with regional growth exceeding 20%/year since 1990 in Ontario and states bordering the Great Lakes. Population numbers, though operating under biological carrying capacity, have exceeded acceptance capacity with several wildlife stakeholder groups throughout Canada and the United States. Stakeholder concerns predominantly focus around social, ecological, and economic values associated with habitat destruction, changes in recreational fisheries, and loss of production at aquaculture facilities. We describe perceptible impacts to these commercial and natural resources, and discuss current research and management …

Status Of Double-Crested Cormorant Phalacrocorax Auritus Research And Management In North America, Scott J. Werner, Shauna L. Hanisch

United States Department of Agriculture Wildlife Services: Staff Publications

The Double-crested Cormorant, the most abundant of North America’s six cormorant species, has rebounded to high numbers after new extirpation in the 1960s and early 1970s. Enhanced environmental regulations and the availability of prey fishes facilitated the resurgence of Double-crested Cormorant populations by the mid-1970s and numbers have continued to increase steadily in most geographic regions through the present. The North American population of Double-crested Cormorants has been estimated at one to two million birds. Concerns about impacts of Double-crested Cormorants on aquacultural stock, sport fish populations, other birds, vegetation, private property, and local economies have been raised. Economic impacts …

Asymptotic Solutions Of Diffusion Models For Risk Reserves, Sally S. L. Shao

Mathematics and Statistics Faculty Publications

We study a family of diffusion models for risk reserves which account for the investment income earned and for the inflation experienced on claim amounts. After we defined the process of the conditional probability of ruin over finite time and imposed the appropriate boundary conditions, classical results from the theory of diffusion processes turn the stochastic differential equation to a special class of initial and boundary value problems defined by a linear diffusion equation. Armedwith asymptotic analysis and perturbation theory, we obtain the asymptotic solutions of the diffusion models (possibly degenerate) governing the conditional probability of ruin over a finite …

Rare-Earth Elements And Nd And Pb Isotopes As Source Indicators For Labrador Sea Clay-Size Sediments During Heinrich Event 2, Larry V. Benson, Don Barber, John T. Andrews, Howard E. Taylor, Paul Lamothe

United States Geological Survey: Staff Publications

Elemental abundances and Nd and Pb isotope ratios were determined on samples from the carbonate-free, clay-size fractions of sediments from intervals above, within, and below Heinrich event 2 (H-2) in core HU87-9 from the Northwest Labrador Sea slope. In HU87-9, rare-earth element (REE) distributions and elemental concentrations within the H-2 event are distinct from those outside this event. ɛ_Nd(0) and ²⁰⁶Pb/²⁰⁴Pb data also indicate different values for sediments deposited within and outside the H-2 event. Comparisons of REE patterns from the H-2 interval with those from bedrock units in Baffin Island, northern Quebec, and Labrador …

The Zigzag Path Of A Pseudo-Triangulation, Oswin Aichholzer, Günter Rote, Bettina Speckmann, Ileana Streinu

Computer Science: Faculty Publications

We define the zigzag path of a pseudo-triangulation, a concept generalizing the path of a triangulation of a point set. The pseudotriangulation zigzag path allows us to use divide-and-conquer type of approaches for suitable (i.e., decomposable) problems on pseudo-triangulations. For this we provide an algorithm that enumerates all pseudotriangulation zigzag paths (of all pseudo-triangulations of a given point set with respect to a given line) in O(n2) time per path and O(n2) space, where n is the number of points. We illustrate applications of our scheme which include a novel algorithm to count the number of pseudotriangulations of a point …

In the title compound, C₈H₈N₂OS, strong intramolecular N—H⋯O hydrogen bonds [N⋯O = 2.669 (3) and 2.618 (3) Å] form almost planar six-membered rings and enforce the conformation of the mol­ecule. Two kinds of intermolecular N—H⋯S hydrogen bonds [N⋯S = 3.309 (3)–3.456 (2) Å] between two symmetry-independent mol­ecules form consecutive dimers that expand in ribbons along the [100] direction.

Improving The Mechanical Properties Of Single-Walled Carbon Nanotube Sheets By Intercalation Of Polymeric Adhesives, Jonathan N. Coleman, Werner J. Blau, Alan B. Dalton, Edgar Munoz, Steve Collins, Bog G. Kim, Joselito M. Razal, Miles Selvidge, Guillermo Vieiro, Ray Baughman

Australian Institute for Innovative Materials - Papers

Organic polymers, such as poly(vinyl alcohol), poly(vinyl pyrrolidone), and poly(styrene), were intercalated into single-walled carbon nanotube sheets by soaking the sheets in polymer solutions. Even for short soak times, significant polymer intercalation into existing free volume was observed. Tensile tests on intercalated sheets showed that the Young's modulus, strength, and toughness increased by factors of 3, 9, and 28, respectively, indicating that the intercalated polymer enhances load transmission between nanotubes.

Zinc Doping Effects On The Structure, Transport And Magnetic Properties Of La0.7sr0.3mn1-Xznxo3 Manganite Oxide, E V. Sotirova-Haralambeva, Xiaolin Wang, Hua-Kun Liu, Tania M. Silver, Konstantin Konstantinov, Josip Horvat

Australian Institute for Innovative Materials - Papers

The processing, microstructures and properties of La_0.7Sr_0.3Mn_1−xZn_xO₃ perovskite manganite, with x=0, 0.1, 0.2, and 0.3 have been investigated. X-ray diffraction, scanning electron microscopy (SEM) and other characterisation methods were used to study the relations of microstructure and properties. The X-ray powder diffraction results show a single phase for the 0<x<0.3 region that confirms the zinc incorporation into the Mn site. The SEM images with magnification 1500× indicate that the studied system is a single phase. The transport measurements show decreasing of insulator to metal transition temperature, T_t, with increasing the zinc concentration on the Mn site, while the resistivity increases with …

Watershed-Scale Agricultural Land-Use Impact On Instream Physicochemical Parameters, William Dillahunty, Indrajeet Chaubey, Marty Matlock

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Nonpoint source (NPS) pollution is often the result of runoff losses from agricultural or urban areas. Even though the watershed approach to controlling NPS pollution is identified as the most efficient approach, data linking watershed scale land use and specific water quality implications are very limited. The objective of this study was to quantify the impact of agricultural land use on stream physico-chemical properties. The upper reach of Flint Creek was monitored at two sampling points draining an agricultural land. At each of these points, continuous measurement of stream characteristics such as temperature, dissolved oxygen (DO) concentration, depth, pH, and …
