Late-Holocene Flooding And Drought In The Northern Great Plains, Usa, Reconstructed From Tree Rings, Lake Sediments And Ancient Shorelines, M. D. Shapley, W. C. Johnson, D. R. Engstrom, W. R. Osterkamp

United States Geological Survey: Staff Publications

During the AD 1990s the Waubay Lakes complex in eastern South Dakota experienced historically unprecedented high water levels. Property damage from this flooding led to an examination of the occurrence of past pluvial episodes and their relation to climate. A lOOO-year hydroclimate reconstruction was developed from local bur oak (Quercus macrocarpa) tree-ring records and lake-sediment cores. Analysis of lake shoreline and drainage features provides late-Quaternary geomorphic context for this high-resolution record. Tree-ring width and shell geochemistry of the ostracode Candona rawsoni show marked coherence, indicating synchronous responses to moisture balance in vegetation and lake salinity; geomorphic evidence …

Omega-3 Fatty Acid Consumption And Food Sources Differ Among Elderly Men Living In Coastal And Internal Regions Of Saudi Arabia, Khalid Al-Numair, Nancy M. Lewis, Sharon Evans

Department of Nutrition and Health Sciences: Faculty Publications

Research suggests that omega-3 fatty acids (n-3 FAs) play an important role in reducing the risk of heart diseases. The objectives of the current study were to investigate the consumption and the food sources of n-3 FAs in two samples of elderly men living in different geographic locations (coastal and internal regions) of Saudi Arabia. Sixty men from each of the coastal and the internal regions provided a 24-hour recall and 2-day food record and a food frequency questionnaire. Food Processor Plus computer program software (ESHA Version 0.7; Salem, Oregon, 2002) was used to analyze the dietary intake. The intake …

Increasing Interest In Parasitology At The Past Three International Mammalogical Congresses Held In 1997, 2001 And 2005: Mammals, Parasites, Zoonoses And Biodiversity, Scott Lyell Gardner, Mitsuhiko Asakawa, Luis A. Ruedas, Kenichi Takahashi

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We summarized the data from the past three TTC (now IMC) meetings to examine the potential trends in presentation of parasites of mammals at the meeting. The lists include titles and authors of papers given in symposia, poster sessions, and oral presentations related to diseases, zoonoses, parasites, and causative agents of diseases of sylvatic mammals. Our analysis shows that there has been an increase in the number of papers (from 2.8% in 1997 to 5.1% in 2005) presented at the International Mammalogical Meetings. We also show that there are potentially more than 27,000 species of parasites (broadly defined) currently inhabiting …

Redescription And New Host Record Of Eimeria Serbica From The Caucasian Tree Squirrel, Sciurus Anomalus, From Turkey, Lee Couch, Atilla Arslan, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Fecal samples from 20 Caucasian tree squirrels, Sciurus anomalus (Gmelin, 1778) Güldenstaedt, 1785, were collected in Turkey during February and March, 2004, and all 20 were infected with a single species of coccidia, Eimeria serbica. Sporulated oocysts are ellipsoidal, 27.5 × 17.5 (21–34 × 15–20) with a length:width ratio (L/W) of 1.6 (1.4–1.8); they lack a micropyle and oocyst residuum, but 0–2 polar granules may be present. Sporocysts are ellipsoidal, 11.9 × 6.9 (10.5–14 × 6–7.5) with a L/W of 1.7 (1.5–2.1); a Stieda body and sporocyst residuum are present.

Pathogenic New Species Of Eimeria From The Pygmy Rabbit, Brachylagus Idahoensis, In Washington And Oregon, With Description Of The Sporulated Oocyst And Intestinal Endogenous Stages, Donald W. Duszynski, Lisa Harrenstien, Lee Couch, Michael M. Garner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

In January 2003, fecal samples from 13 live pygmy rabbits, Brachylagus idahoensis (Merriam, 1891), were collected at the Oregon Zoo in Portland, Oregon, and sent to the University of New Mexico (UNM), Albuquerque, New Mexico, to be examined for coccidia. In July 2004, 14 more fecal samples were collected and sent to UNM, 6 from some of the same rabbits and 8 from 16 other rabbits (4 were pooled samples from siblings). In addition, tissue sections from 3 dead rabbits (2 from the Oregon Zoo, 1 from Washington State University) also were examined. Two of 4 (50%) pooled fecal samples …

Eimeria Species (Apicomplexa: Eimeriidae) From Arctic Ground Squirrels (Spermophilus Parryii ) And Red Squirrels (Tamiasciurus Hudsonicus) In Alaska And In Siberia, Russia, Robert S. Seville, Clint E. Oliver, Andrew J. Lynch, Michelle C. Bryant, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Fecal samples from arctic ground squirrels (Spermophilus parryii) collected in Alaska (n = 90) and Russia (n = 46) and from red squirrels (Tamiasciurus hudsonicus) in Alaska (n = 35) were examined for the presence of Eimeria spp. (Apicomplexa: Eimeriidae). Four species were recovered from arctic ground squirrels, including Eimeria callospermophili (prevalence = 18%), Eimeria cynomysis (23.5%), Eimeria lateralis (19%), and Eimeria morainensis (77%). A single species, Eimeria tamiasciuri (91%), was recovered from red squirrels. Eimerians recovered from arctic ground squirrels represent new host records, and the single species from red squirrels is …

Parasites Of The American White Pelican, Robin M. Overstreet, Stephen S. Curran

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Metazoan symbionts, including parasites, infecting the American white pelican (AWP) Pelecanus erythrorhynchos comprise a list of 75 species, 7 of which are new host records. Several new geographic records are also presented, but generally these have a low value because of the migratory nature of the bird. Evidence suggests that some parasites, mostly flies and other arthropods but also nematodes and digeneans, produce detrimental behavioral or pathologic changes in the AWP. Some of the arthropods transmit microbial agents to the pelican. Two digeneans that have the AWP as a definitive host harm and even kill their catfish intermediate host, especially …

The Pathologic Copepod Phrixocephalus Cincinnatus (Copepoda: Pennellidae) In The Eye Of Arrowtooth Flounder, Atherestes Stomias, And Rex Sole, Glyptocephalus Zachirus, From British Columbia, Reginald B. Blaylock, Robin M. Overstreet, Alexandra B. Morton

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We report Phrixocephalus cincinnatus, a pennellid copepod infecting the eyes of flatfishes, from a single specimen of rex sole, Glyptocephalus zachirus, for the first time. In the typical host, the arrowtooth flounder, Atherestes stomias, the parasite occurred commonly in sampled populations from the Broughton Archipelago in British Columbia, infected primarily the right eye of the flounder, and on only one occasion presented more than two parasites per eye. The copepod attached to the choroid layer and ramified throughout the posterior compartment of the eye, resulting in the disruption of the retina and probably impairing host vision. Inflammation …

Status Of Oral Rabies Vaccination In Wild Carnivores In The United States, Dennis Slate, Charles E. Rupprecht, Jane A. Rooney, Dennis Donovan, Donald H. Lein, Richard B. Chipman

United States Department of Agriculture Wildlife Services: Staff Publications

Persistence of multiple variants of rabies virus in wild Chiroptera and Carnivora presents a continuing challenge to medical, veterinary and wildlife management professionals. Oral rabies vaccination (ORV) targeting specific Carnivora species has emerged as an integral adjunct to conventional rabies control strategies to protect humans and domestic animals. ORV has been applied with progress toward eliminating rabies in red foxes (Vulpes vulpes) in western Europe and southern Ontario, Canada. More recently since 1995, coordinated ORV was implemented among eastern states in the U.S.A. to prevent spread of raccoon (Procyon lotor) rabies and to contain and eliminate …

Prometheus Radio Project V. Fcc: The Persistence Of Scarcity, Aaron Perzanowski

Articles

Part I traces the history of broadcast regulation, emphasizing the development of the scarcity doctrine and the subsequent deregulatory trend. Part II examines the FCC's 2003 rule changes and the Third Circuit's analysis of those modifications in Prometheus Radio Project v. FCC. Part III analyzes the assumptions underlying the FCC's proffered explanation for its rule changes, ultimately concluding that they lack justification, and offers suggestions for responsible ownership deregulation. Part IV calls on Congress to reassert itself as the final arbiter of media policy.

Detection Of Deformable Objects In A Non-Stationary Scene, Sherif Azary

Theses

Image registration is the process of determining a mapping between points of interest on separate images to achieve a correspondence. This is a fundamental area of many problems in computer vision including object recognition and motion tracking. This research focuses on applying image registration to identify differences between frames in non-stationary video scenes for the purpose of motion tracking. The major stages for the image registration process include point detection, image correspondence, and an affine transformation. After applying image registration to spatially align the image frames and detect areas of motion segmentation is applied to segment the moving deformable objects …

An Investigation Of Techniques In Deformable Object Recognition, Gavin S. Page

Theses

The human's innate ability to process information garnered from a visual scene has no parallel in the digital realm. This task is taken for granted in human cognition, but has not been met by a complete digital solution even following years of research. This difficulty can be explained by the shear complexity of the physology of the visual pathway. Although a complete solution has not been created, there are a number of examples of solutions that address parts of the problem. The recognition of deformable objects is the area addressed in this work. The specific task researched was the recognition …

Articles

Mr. Chairman, colleagues, and friends: It is a great honor for me to be able to address this group of experts and legislators, and many colleagues and friends, on a topic I care deeply about-the regulation of so-called public companies, both outside of China and, since the early 1990s, inside of China. First, and with many of the others invited to participate in this conference today and tomorrow, I thank the Office of Legislative Affairs ("OLA") of the State Council of the People's Republic of China ("PRC") as well as the China Securities Regulatory Commission ("CSRC") for convening this very …

Security In Serverless Network Environments, Carl Holtje

Theses

As portable computing devices grow in popularity, so does the need for secure communications. Lacking tethers, these devices are ideal for forming small proximal groups in an ad-hoc fashion in environments where no server or permanent services are available. Members of these groups communicate over a broadcast or multicast network interconnect, and rely upon each other to form a cohesive group. While generally small in size and short in lifetime, security is a critical aspect of these groups that has received much academic attention in recent years. Much of the research focuses upon generating a common, group-wide private key suitable …

A Comparison Of Reputation-Based Trust Systems, John Folkerts

Theses

Recent literature contains many examples of reputation systems which are constructed in an ad hoc way or rely upon some heuristic which has been found to be useful. However, comparisons between these reputation systems has been impossible because there are no established methods of comparing performance. This paper introduces a simulation framework which can be used to perform comparison analysis between reputation models. Two reputation models, one from Abdul-Rahman and Hailes (ARH) [1], and one from Mui, Mohtashemi, and Halberstadt (MMH) [17] are implemented and compared with regard to accuracy, performance and resistance to deception. In order to improve performance …

Reforming Higher Education In Saudi Arabia: The Use Of Telecommunications Technology, Abdullah Altowjry

Theses

Internet technology has become a powerful tool since its advent. Online learning is a byproduct of Internet usage and is instrumental in higher education. In the United States, the use of online learning, also known as distance learning, is widespread. It is used in almost all educational institutions. Even third world countries, which are traditionally lagging behind in any educational or sociological enterprise, are now attempting to catch up with distance learning education. Some educational institutions in the Middle East, for example, have been using distance learning in place of traditional classroom instruction. In Saudi Arabia, there is a great …

The Nature Of Arbitral Authority: A Comment On Lesotho Highlands, William W. Park

Faculty Scholarship

Arbitration unfolds within an enclosure created by the contract terms and the applicable arbitration law. Some measure of judicial scrutiny must be imposed to ensure that an award does not fall beyond an arbitrator’s authority. But how should one identify excess of authority? The House of Lords decision in Lesotho Highlands v. Impreglio serves as a prism through which to separate several themes that inhere in the nature of arbitral authority. In rejecting arguments that an error about the currency of an award represented an excess of jurisdiction, their Lordships confirmed a healthy appreciation that arbitrators do not exceed their …
