Effects Of Trapping And Subsequent Short-Term Confinement Stress On Plasma Corticosterone In The Brown Treesnake (Boiga Irregularis) On Guam, Tom Mathies, Todd A. Felix, Valentine A. Lance

United States Department of Agriculture Wildlife Services: Staff Publications

The effects of capture in a live trap and subsequent handling stress on plasma concentrations of corticosterone and other sex steroids were examined in wild male and female brown treesnakes (Boiga irregularis), an introduced species on Guam that has been implicated in the extirpation or decline of many of that island's vertebrate species. Males and females that spent 1 night in a trap had plasma levels of corticosterone about four and two times higher, respectively, than those of the respective free-ranging controls. Mean plasma levels of corticosterone of snakes that had spent 3 nights in a trap were …

Porcine Zona Pellucida Immunocontraception: Long-Term Health Effects On White-Tailed Deer, Lowell A. Miller, Ken Crane, Stan Gaddis, Gary J. Killian

United States Department of Agriculture Wildlife Services: Staff Publications

As part of a 9-year study on the contraceptive effects of Porcine Zona Pellucida (PZP) on white-tailed deer (Odocoileus virginianus), we analyzed serum chemistry panels during the first 4 years. This included the first 2 years when does were being actively immunized, and 2 years post-immunization. The chemistry panel was designed to detect pathologies that might result from the immunization of the deer. Blood chemistry results did not suggest any pathological changes resulting from the immunization. Seasonal differences in serum cholesterol were similar in both the control and PZP-treated groups. Seasonal changes in the mean body weights of …

Organic Vegetables : A Guide To Production, Steven Mccoy

Bulletins 4000 -

There appears to be considerable opportunity for the development of organic vegetable production in Western Australia for either fresh or processed product. While a number of growers are successfully producing relatively small quantities of organic vegetables for both domestic and export markets, few large scale commercial growers have sought to capitalise on this opportunity.

Consumer interest in organically grown vegetables has increased rapidly in recent years due largely to concerns relating to food safety, health and the environment. For more information on markets for organic vegetables refer to AGWEST publication “Market Prospects – Organic Carrots and other Vegetables”.

Rancho West Estates Water Distribution System Replacement Funding Project, Sherry Evans-Carmichael

Water Resources Professional Project Reports

The Rancho West Mobile Home Association (RWMHA or Association) needed funding to replace the aging Rancho West Estates (RWE) water distribution system to ensure a dependable future water supply, in terms of quality and quantity, for association members and residents of the RWE. The RWMHA did not qualify for commercial loans and did not have enough money to pay for the project. Association Board members stated working to obtain finding to replace the water distribution system in 1996. RWMHA Board members were very concerned about the health and welfare of all members and residents of the RWE. Concerns that were …

Microbially Mediated Reduction And Immobilization Of U(Vi) In Groundwater At A Site In Konigstein, Germany, Danielle D. Diehl

Water Resources Professional Project Reports

Groundwater supplies are increasingly threatened by organic, inorganic and radioactive contaminants introduced to the environment by improper disposal or accidental release. WISMUT, a German government owned company conducted in situ acid leach mining for decades to extract uranium from a mine at Konigstein. The uranium mine is currently undergoing remediation. The first objective of this research is to determine whether dissolved U(VI) can be precipitated via microbially mediated reduction to its insoluble form.

Decline Of The Red-Winged Blackbird Population In Ohio Correlated To Changes In Agriculture (1965-1996), Bradley F. Blackwell, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Based on North American Breeding Bird Survey (BBS) data since 1966, Ohio has traditionally hosted 1 of the highest breeding season densities of red-winged blackbirds (Agelaius phoeniceus) of any U.S. state or Canadian province. However, from 1966 through 1996, breeding populations of red-winged blackbirds in Ohio showed a marked decline (x̅ % change/yr in birds per route = -3.9), with breeding population indices decreasing by over 53%. Because the red-winged blackbird successfully adapted to habitats created by agricultural expansion over the last century and became a recognized pest of crops such as corn (Zea mays), …

A Statistical Study Of Transient Event Motion At Geosynchronous Orbit, Jeff Sanny, David Berube, D. G. Sibeck

Physics Faculty Works

The geosynchronous GOES 5 and GOES 6 satellites frequently observe transient events marked by magnetic field strength increases and bipolar magnetic field signatures lasting several minutes. In this study we report a survey of 87 events observed simultaneously by both GOES spacecraft (for a total of 174 individual observations) from August to December 1984. Events detected in the prenoon sector outnumbered those in the postnoon sector by about a 3 to 1 ratio. The distribution of the events versus local time exhibited a significant prenoon peak like the distribution of magnetic impulse events observed in high-latitude ground magnetometers. A cross-correlation …

A Preliminary Survey Of The Sewage Pumpout Facilities In The No Discharge Areas Of Massachusetts, Urban Harbors Institute, University Of Massachusetts Boston

Urban Harbors Institute Publications

This survey provides a preliminary review of the activities of pumpout facilities in the No Discharge Areas of Massachusetts. It highlights areas of concern, identifies potential improvements and focuses further research.

Based on data from Massachusetts Coastal Zone Management, there are 100 pumpout facilities in Massachusetts, located in 56 towns. Of these 52, have one or more pumpout boats. Due to financial limitations and the time available, any attempt to survey all these facilities was beyond the scope of this study. However, it had been suggested that from CZM’s, DMF’s and EPA’s standpoint, the areas of greatest interest were those …

Scientific Ignorance And Reliable Patterns Of Evidence In Toxic Tort Causation: Is There A Need For Liability Reform?, Carl F. Cranor, David A. Eastmond

Law and Contemporary Problems

As a first step to preserving the central aims of tort law, courts will need to recognize the wide variety of respectable, reliable patterns of evidence on which scientists themselves rely for drawing inferences about the toxicity of substances. Courts may also need to take further steps to address the woeful ignorance about the chemical universe. This may necessitate changes in the liability rules.

The Swine Flu Vaccine And Guillain-Barré Syndrome: A Case Study In Relative Risk And Specific Causation, David A. Freedman, Philip B. Stark

Law and Contemporary Problems

This article discusses the role of epidemiologic evidence in toxic tort cases, focusing on relative risk. Whether specific causation can be inferred if a relative risk is above 2.0 is discussed. The object is to explore the scientific logic behind intuitions of relative risk.

Scientific Models Of Human Health Risk Analysis In Legal And Policy Decisions, Douglas Crawford-Brown

Law and Contemporary Problems

The quality of scientific predictions of risk in the courtroom and policy arena rests in large measure on how the two differences between normal practice and the legal/policy practice of science are reconciled. This article considers a variety of issues that arise in reconciling these differences, and the problems that remain with scientific estimates of risk when these are used in decisions.

Rationalism And Empiricism In Modern Medicine, Warren Newton

Law and Contemporary Problems

Weed Plan For Western Australia, State Weed Plan Steering Group, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

One of the most significant environmental challenges facing Western Australia is the minimisation of the impact of weeds. In the relatively short history of this State since European settlement, some 1155 exotic plant species have established as weeds in our diverse and generally fragile ecosystems. While development for agriculture, mining, transport and housing must by its nature result in some change to the State’s flora, the introduction of weedy plant species has caused serious impacts which cause great concern.

Weeds now pose a serious threat to many of the State’s ecosystems, and impose high annual costs on agricultural industries. Weeds …

Island Arcs, Accretionary Terranes And Midcontinent Structure New Understandings Of The Geologic Architecture Of The U.S. Midcontinent, Marvin P. Carlson

Conservation and Survey Division: Faculty and Staff Publications

A data base collected over the last 100 years, containing both surface and subsurface information, has allowed us to begin to understand the physical framework of Nebraska. We have learned that even in the stable Midcontinent region of North America, there has been an active geologic history. This framework has been deciphered by our programs of surface geologic mapping and by the study of rock samples from both water wells and those deeper test wells for oil and gas. Determining the major structural features across the state (figure 1) has allowed us to better understand both the occurrences of its …

Energetics And Cooperativity In Three-Center Hydrogen Bonding Interactions. Ii. Intramolecular Hydrogen Bonding Systems, Ruben D. Parra, Bing Gong, Xiao Cheng Zeng

Xiao Cheng Zeng Publications

High level ab initio calculations have been carried out on a number of intramolecular two- and three-center H-bonding structures containing the amide motif, NHC=O. These structures serve as model systems for probing the stability of intramolecular three-center H bonds of the type A₁HA₂. Particular attention is given to cooperative effects in the three-center H-bonding structures. A systematic assessment of cooperativity for intramolecular H-bonding systems is presented.

Monte Carlo Studies Of Mott Scattering Asymmetries From Gold Foils, M. A. Khakoo, D. Roundy, C. Hicks, N. Margolis, E. Yeung, A. W. Ross, Timothy J. Gay

Timothy J. Gay Publications

We present the results of a series of model Monte Carlo calculations of the scattering of spin-polarized electrons from gold foil targets. Our calculations examine the behavior of the left-right scattering asymmetry A as a function of various parameters conventionally used in extrapolation of the left-right asymmetry to single atom and/or elastic scattering conditions. These parameters include target thickness, scattered count rate, and the maximum energy that an electron can have lost in the target and still be detected. Data are obtained at incident electron energies of 10–120 keV, with detector-subtended half-cone angles of 5°, 10°, and 20°, and gold …

Efficacy Of Wolfin To Repel Black-Tailed Deer, Dale L. Nolte, Kimberly K. Wagner

United States Department of Agriculture Wildlife Services: Staff Publications

Deer and elk provide many desirable recreational opportunities but also can cause severe conflicts with humans. Excluding them from agricultural resources or from roadways is desirable, but fencing is expensive. A chemical barrier would offer a feasible alternative to reduce damage caused by deer. A series of three tests was conducted to assess whether black-tailed deer avoided areas treated with Wolfin, a synthetic predator odor. Wolfin failed to repel deer during any of these trials. We conclude that Wolfin, as applied within this study, is unlikely to reduce problems roused by free-ranging deer. West. J Appl. For. 16(4):182-186.

The Standardized Fish Bioassay Procedure For Detecting And Culturing Actively Toxic Pfiesteria, Used By Two Reference Laboratories For Atlantic And Gulf Coast States, Joann M. Burkholder, Harold G. Marshall, David W. Seaborn, Nora J. Deamer-Melia

Biological Sciences Faculty Publications

In the absence of purified standards of toxins from Pfiesteria species, appropriately conducted fish bioassays are the "gold standard" that must be used to detect toxic strains of Pfiesteria slop. from natural estuarine water or sediment samples and to culture actively toxic Pfiesteria. In this article, we describe the standardized steps of our fish bioassay as an abbreviated term for a procedure that includes two sets of trials with fish, following the Henle-Koch postulates modified for toxic rather than infectious agents. This procedure was developed in 1991, and has been refined over more than 12 years of experience in …

Modeling And Simulation Of Steady State And Transient Behaviors For Emergent Socs, Joann M. Paul, Arne Suppe, Donald E. Thomas

Research Collection School Of Computing and Information Systems

We introduce a formal basis for viewing computer systems as mixed steady state and non-steady state (transient) behaviors to motivate novel design strategies resulting from simultaneous consideration of function, scheduling and architecture. We relate three design styles: Hierarchical decomposition, static mapping and directed platform that have traditionally been separate. By considering them together, we reason that once a steady state system is mapped to an architecture, the unused processing and communication power may be viewed as a platform for a transient system, ultimately resulting in more effective design approaches that ease the static mapping problem while still allowing for effective …

On Clustering And Retrieval Of Video Shots, Chong-Wah Ngo, Ting-Chuen Pong, Hong-Jiang Zhang

Research Collection School Of Computing and Information Systems

Clustering of video data is an important issue in video abstraction, browsing and retrieval. In this paper, we propose a two-level hierarchical clustering approach by aggregating shots with similar motion and color features. Motion features are computed directly from 20 tensor histograms, while color features are represented by 30 color histograms. Cluster validity analysis is further applied to automatically determine the number of clusters at each level. Video retrieval can then be done directly based on the result of clustering. The proposed approach is found to be useful particularly for sports games, where motion and color are important visual cues …

Jointly Coordinating Ecn And Tcp For Rapid Adaptation To Varying Bandwidth, Archan Misra, Teunis Ott

Research Collection School Of Computing and Information Systems

The introduction of service differentiation in the Internet implies that the residual bandwidth available to best-effort traffic becomes highly variable. We explore the design of a rapidly-reactive congestion control framework, where the ECN-aware best-effort flows aggressively go after any unused capacity. By making routers mark packets in a much more aggressive manner, we are able to achieve fast backoff in the network without resorting to the TCP's current drastic step of halving the congestion window. Simulations indicate that our ECN-mod protocol is better than ECN-NewReno in exploiting rapid variations in the available bandwidth. Moreover, the milder backoff policy of ECN-mod …
