Chemical Bonds Broken In Latent Tracks Of Light Ions In Plastic Track Detectors, R. Barillon, M. Fromm, Robert Katz, A. Chambaudet

Robert Katz Publications

When a swift ion is slowed down through a plastic detector it creates a latent track. In nuclear track detectors, this latent track can be specifically etched by an appropriate chemical solution. This enlargement process is due to a higher etch velocity (V_T) along the ion's path than in the non-damaged part of the detector. The etched track velocity is definitely linked to the damage created by the incoming ion in the detector material. A relationship between the physical parameters of the energy deposition and the variation in this etched track velocity with the ion energy cannot easily …

Proposal Of Critical Habitat For The Northern Great Plains Breeding Population Of Piping Plovers (Charadrius Melodus)

United States Fish and Wildlife Service: Publications

The purpose of the proposed action is to designate critical habitat for the northern Great Plains breeding population of piping plovers (Charadrius melodus) by utilizing provisions of the Endangered Species Act of 1973, as amended (Act). The purpose of the Act is to conserve the ecosystems upon which endangered and threatened species depend. Critical habitat designation identifies areas essential to the survival and recovery of the piping plover, and describes physical and biological features within critical habitat that require special management considerations to achieve conservation of the species.

Selection Of Nesting Habitat By Sharptailed Grouse In The Nebraska Sandhills, Bart L. Prose, Brian S. Cade, Dale Hein

United States Geological Survey: Staff Publications

We evaluated nesting habitat selection (disproportionate use compared to availability) by plains sharp-tailed grouse (Tympanuchus phasianellus jamesi) on rangelands grazed by cattle (Bas taurus) relative to height, density, and heterogeneity of residual herbaceous vegetation remaining from previous growing seasons. Residual cover is critical for nesting sharp-tailed grouse and can be lacking on grazed rangelands. Aerial photography and a geographic information system were used to analyze residual cover height classes and several measures of residual cover heterogeneity in nest (n = 38) and random (n = 38) plots. Height classes corresponded to visual obstruction readings (YORs), the …

Morphometric Analysis Of Nonadult Characters Of Common Species Of American Gordiids (Nematomorpha: Gordioidea), Ben Hanelt, John J. Janovy Jr.

John J. Janovy, Jr. Publications

The nonadult stages, egg strings, eggs, larvae, and cysts of Gordius robustus, Paragordius varius, and Chordodes morgani are described morphometrically. The goal was to document the differences between species and to evaluate the usefulness of morphometrics in species identification. In concert, multivariate analysis of variance (MANOVA) and univariate analysis of variance (ANOVA, a posteriori contrasts) statistical tests demonstrated that each species is morphometrically distinguishable from all others. Additionally, discriminant function analysis indicated that postseptum length, pseudointestine length, and stylet width were the most important variables in the discrimination of species based on larval characters. Finally, differences in oviposition behaviors …

Minireview: How Selenium Has Altered Our Understanding Of The Genetic Code, Dolph L. Hatfield, Vadim Gladyshev

Vadim Gladyshev Publications

Selenium is an essential micronutrient in the diet of many life forms, including humans and other mammals. Significant health benefits have been attributed to this element. It is rapidly becoming recognized as one of the more promising cancer chemopreventive agents (19), and there are strong indications that it has a role in reducing viral expression (4), in preventing heart disease and other cardiovascular and muscle disorders (23), and in delaying the progression of AIDS in human immunodeficiency virus-infected patients (3). Additional evidence suggests that selenium may have a role in mammalian development (51), in immune function (70), in male reproduction …

Using Inert Dusts To Detect And Assess Varroa Infestations In Honey Bee Colonies, P. A. Macedo, J. Wu, Marion D. Ellis

Department of Entomology: Faculty Publications

Detection and assessment of varroa infestations in honey bee colonies are important for successful beekeeping. We examined the use of inert dusts to dislodge mites from adult honey bees that were isolated from their nest. Six dusts (powdered sugar, fine sugar, wheat flour, talcum powder, corn starch and baking soda) were evaluated for their ability to dislodge mites from adult bees collected in jars. We obtained the highest recovery rate with powdered sugar (92.9 ± 5.5%) and talcum powder (84.0 ± 5.6%). We also examined mite survival after recovery with inert dusts and compared it to mite survival after recovery …

Unexpected Ecological Effects Of Distributing The Exotic Weevil, Larinus Planus (F.), For The Biological Control Of Canada Thistle, Svata M. Louda, Charles W. O'Brien

Svata M. Louda Publications

Rhinocyllus conicus, a weevil introduced for biological control of exotic weeds, has had major nontarget ecological effects on native thistles. Some practitioners have argued that this is an isolated case. We report, however, that another Eurasian weevil (Larinus planus), currently being distributed in North America for the control of Canada thistle (Cirsium arvense), is significantly reducing seed production by a native thistle (Tracy’s thistle, Cirsium undulatum var. tracyi) in Colorado. In 1999 we discovered L. planus feeding in flower heads of Tracy’s thistle near a 1992–1993 biocontrol release site. Of the heads collected, 74% …

Bolbophorus Damnificus N. Sp. (Digenea: Bolbophoridae) From The Channel Catfish Ictalurus Punctatus And American White Pelican Pelecanus Erythrorhynchos In The Usa Based On Life-Cycle And Molecular Data, Robin M. Overstreet, Stephen S. Curran, Linda M. Pote, D. Tommy King, Charles K. Blend, Walter D. Grater

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The common pathogenic prodiplostomulum metacercaria in the flesh, mostly near the skin, of pond-produced channel catfish Ictalurus punctatus has been demonstrated to be Bolbophorus damnificus Overstreet & Curran n. sp. The catfish acquires the infection from the snail Planorbella trivolvis, the only known first intermediate host, and the species is perpetuated through the American white pelican Pelecanus erythrorhynchos, as confirmed by experimental infections with nestling and dewormed adult pelican specimens in conjunction with molecular data. It differs from the cryptic species Bolbophorus sp., also found concurrently in the American white pelican, by having eggs 123–129 μm rather …

Retrograde Transport Of Transmissible Mink Encephalopathy Within Descending Motor Tracts, Jason C. Bartz, Anthony E. Kincaid, Richard A. Bessen

Nebraska Center for Virology: Faculty Publications

The spread of the abnormal conformation of the prion protein, PrP^Sc, within the spinal cord is central to the pathogenesis of transmissible prion diseases, but the mechanism of transport has not been determined. For this report, the route of transport of the HY strain of transmissible mink encephalopathy (TME), a prion disease of mink, in the central nervous system following unilateral inoculation into the sciatic nerves of Syrian hamsters was investigated. PrP^Sc was detected at 3 weeks postinfection in the lumbar spinal cord and ascended to the brain at a rate of approximately 3.3 mm per day. …

Policymaking Network Of The Iron-Triangle Subgovernment For Licensing Hazardous Waste Facilities, F. Gregory Hayden

College of Business: Faculty Publications

The purposes here are to explain the linkage of (1) economic methodology, (2) corporate networks, and (3) federal court decisions in the licensing of hazardous waste facilities and to recognize the opportunity the combination of the three provides for institutional economists. The United States has the best and most comprehensive set of laws we might expect from a legislative process in order to prevent human disease, loss of property, and ecological system destruction from hazardous, toxic, and radioactive waste. Yet the licensing process and assessment that has grown out of that legislation has not produced the protection expected. The waste …

Ornithine Decarboxylase Encoded By Chlorella Virus Pbcv-1, Tiara A. Morehead, James R. Gurnon, Byron Adams, Kenneth Nickerson, Lisa A. Fitzgerald, James L. Van Etten

Nebraska Center for Virology: Faculty Publications

Sequence analysis of the 330-kb genome of chlorella virus PBCV-1 revealed an open reading frame, A207R, which encodes a protein with 37–41% amino acid identity to ornithine decarboxylase (ODC) from many eukaryotic organisms. The a207r gene was cloned and the protein was expressed as a His-A207R fusion protein in Escherichia coli. The recombinant protein catalyzes pyridoxal 5’-phosphate-dependent decarboxylation of ornithine to putrescine, the first step in the polyamine biosynthetic pathway The enzyme has a pH optimum of 9.0 and a temperature optimum of 42°C, and it requires dithiothreitol for maximal activity. The enzyme has a Km, for ornithine of …

Testis Developmental Phenotypes In Neurotropin Receptor Trka And Trkc Null Mutations: Role In Formation Of Seminiferous Cords And Germ Cell Survival, Andrea S. Cupp, Lina Tessarollo, Michael K. Skinner

Department of Animal Science: Faculty Publications

The objective of the present study was to determine if the neurotropin receptors trkC and trkA are involved in embryonic testis development. These receptors bind neurotropin 3 and nerve growth factor, respectively. The hypothesis tested was that the absence of trkC or trkA receptors will have detrimental effects on testis development and morphology. The trkA and trkC homozygote knockout (KO) mice generally die either at or shortly after birth. Therefore, heterozygote mice were mated to obtain homozygote gene KO mice at Embryonic Day (E) 13, E14, E17, and E19 of gestation, with E0 being the plug date. Gonads from approximately …

Direct Haplotyping Of Kilobase-Size Dna Using Carbon Nanotube Probes, Adam T. Woolley, Chantal Guillemette, Chin Li Cheung, David E. Housman, Charles M. Lieber

Barry Chin Li Cheung Publications

We have implemented a method for multiplexed detection of polymorphic sites and direct determination of haplotypes in 10-kilobasesize DNA fragments using single-walled carbon nanotube (SWNT) atomic force microscopy (AFM) probes. Labeled oligonucleotides are hybridized specifically to complementary target sequences in template DNA, and the positions of the tagged sequences are detected by direct SWNT tip imaging. We demonstrated this concept by detecting streptavidin and IRD800 labels at two different sequences in M13mp18. Our approach also permits haplotype determination from simple visual inspection of AFM images of individual DNA molecules, which we have done on UGT1A7, a gene under study as …
