Ultrasound Three- Dimensional Velocity Measurements By Feature Tracking, Gregory R. Bashford, Olaf T. Von Ramm

Biomedical Imaging and Biosignal Analysis Laboratory

This article describes a new angle-independent method suitable for three-dimensional (3-D) blood flow velocity measurement that tracks features of the ultrasonic speckle produced by a pulse echo system. In this method, a feature is identified and followed over time to detect motion. Other blood flow velocity measurement methods typically estimate velocity using one- (1-D) or two-dimensional (2-D) spatial and time information. Speckle decorrelation due to motion in the elevation dimension may hinder this estimate of the true 3-D blood flow velocity vector. Feature tracking is a 3-D method with the ability to measure the true blood velocity vector rather than …

Empirical Valuation Of Prairie Potholes: Five Case Studies, Jay A. Leitch, Brett Hovde

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Dollar values were estimated for four prairie potholes and a wetland complex in North Dakota. Assessing these values required careful consideration of the ecological values and the societal values on a site-specific basis. Assessments of value were made from four perspectives owner, user, regional, and social. Values of specific outputs and total values varied among the five study sites. Annual per hectare values varied from the $10 owner value for the Nome wetland to the $921 regional value for the Alice wetland. The greatest analytical obstacle to obtaining more refined estimates was the physical and biological data needed to technically …

Review Of Wild Animals And Settlers On The Great Plains By Eugene D. Fleharty, Charles A. Flowerday

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Wild Animals and Settlers on the Great Plains is an informative but flawed book. As an example of environmental history written by a biologist unacquainted with the fundamentals of doing history, it fails to offer any theory (or theories) of history governing the time and place under scrutiny. What it does provide is a huge amount of information drawn from diaries, letters, and newspapers in an inadequately edited form. Lacking primary quantitative data, Eugene Fleharty, a zoologist at Fort Hays State University in Hays, Kansas, painstakingly provides a great deal of qualitative, albeit anecdotal, information about Euro-American settlement in Kansas …

Tyrosine Kinase-Dependent Release Of An Adenovirus Preterminal Protein Complex From The Nuclear Matrix, Peter C. Angeletti, Jeffrey A. Engler

Nebraska Center for Virology: Faculty Publications

Adenovirus (Ad) replicative complexes form at discrete sites on the nuclear matrix (NM) through the interaction of Ad preterminal protein (pTP). The NM is a highly salt-resistant fibrillar network which is known to anchor transcription, mRNA splicing, and DNA replication complexes. Incubation of rATP with NM to which pTP was bound caused the release of pTP as a pTP-NM complex with a size of 220 to 230 kDa; incubation with 5’ adenylylimidodiphosphate (rAMP-PNP) showed no significant release, indicating that rATP hydrolysis was required. With NM extracts, it was shown that a pTP-NM complex which was capable of binding Ad origin …

Molecular Systematics Of The Fruit Bat, Artibeus Jamaicensis: Origin Of An Unusual Island Population, Dorothy E. Pumo, Iksoo Kim, James Remsen, Carleton J. Phillips, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

DNA sequences from mitochondrial tRNA genes, the light strand replication site, and a region of the 12s rRNA gene were used to test the hypothesis that the unusual Antillean island subspecies, Artibeus jamaicensis schwartzi, was derived from a South American origin. Parsimony and bootstraping analyses allied the mitochondrial genome in these bats with mitochondrial DNA (mtDNA) isolated from Artibeus planirostris living in French Guiana rather than with mtDNA isolated from Artibeus jamaicensis from the Antilles or Mexico. Although the tRNA sequences differed slightly, the 12s rRNA sequences were identical in mtDNA isolated from A. j. schwartzi on St. Vincent …

Effect Of Screw Configuration And Speed On Rtd And Expansion Of Rice Extrudate, Siew-Yoong Lee, Kathryn L. Mccarthy

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

The influence of screw configuration and screw speed on the residence time distribution and product expansion was determined for rice meal processed in a corotating twin screw extruder. Screw speed had strong effect on the E(t)- and F(t)-diagrams, with the mean residence time varying inversely with screw speed from 206 s to 256 s. the F-diagram was modeled by the combination of perfect mixing and plug flow. the P estimates, which express the fraction of material in plug flow, varied inversely with screw speed from 0.41 to 0.55 for the operating conditions in this study. Both screw configuration and screw …

A New Species Of Acanthobothrium Van Beneden, 1849 (Eucestoda: Tetraphyllidea: Onchobothriidae) In Dasyatis Longus Garman (Chondrichthyes: Myliobatiformes: Dasyatididae) From Chamela Bay, Jalisco, Mexico, Scott Monks, Daniel R. Brooks, Gerardo Pérez-Ponce De León

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A new species of Acanthobothrium in Dasyatis longus from Chamela Bay, Jalisco, Mexico, is a member of a presumed clade of species diagnosed by being anapolytic or nearly so, having more than 100 testes per proglottis, with immature and mature proglottides wider than long to square, aspinose scolex, muscular bothridia fused to the scolex at their posterior ends, H- to V-shaped ovaries, relatively short symmetrical to asymmetrical ovarian arms that extend anteriorly to, or nearly to, the cirrus sac, and vitellaria arranged in fields rather than a single row of follicles. The new species most closely resembles Acanthobothrium terezae from …

Characterization Of Crystalline Formate Dehydrogenase H From Escherichia Coli, Vadim N. Gladyshev, Jeffrey C. Boyington, Sergei V. Khangulov, David Grahame, Thressa C. Stadtman, Peter D. Sun

Vadim Gladyshev Publications

The selenocysteine-containing formate dehydrogenase H (FDH) is an 80-kDa component of the Escherichia coli formate-hydrogen lyase complex. The molybdenumcoordinated selenocysteine is essential for catalytic activity of the native enzyme. FDH in dilute solutions (30 μg/ml) was rapidly inactivated at basic pH or in the presence of formate under anaerobic conditions, but at higher enzyme concentrations ( 3 mg/ml) the enzyme was relatively stable. The formate-reduced enzyme was extremely sensitive to air inactivation under all conditions examined. Active formate-reduced FDH was crystallized under anaerobic conditions in the presence of ammonium sulfate and PEG 400. The crystals diffract to 2.6 Å resolution …

The Structural Gene Encoding Human Enterotoxigenic Escherichia Coli Pcfo20 Is Homologous To That For Porcine 987p, Gloria Inés Viboud, Gunhild Jonson, Evelyn A. Dean-Nystrom, Ann-Mari Svennerholm

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Putative colonization factor PCFO20 was recently identified in an enterotoxigenic Escherichia coli (ETEC) strain of serogroup O20 isolated from a child with diarrhea in Argentina. The gene encoding the structural subunit of PCFO20 fimbriae, fotA, was cloned from strain ARG-2 in the expression phage vector lambda ZAP Express. One positive clone, pGV29, that carried a 3.3-kb fragment was identified on the basis of fimbrillin production by using a monospecific rabbit anti-PCFO20 serum. Nucleotide sequencing of a 1.3-kb Sau3A-ClaI fragment of the subclone pGV292 containing the region coding for PCFO20 fimbrillin revealed two open reading frames of …

Comments On The Distribution Of Botrychium Lunarioides (Ophioglossaceae) In Texas, W. C. Holmes, T. L. Morgan, Jeffrey R. Stevens, R. D. Gooch, J. R. Singhurst

Department of Psychology: Faculty Publications

Botrychium lunarioides (Michx.) Sw. (Ophioglossaceae) is now known to be widespread and abundant throughout the eastern portion of Texas. In 1996, Do, et al. reported ten additional county records in the central portion of the Post Oak Savannah of Texas, thereby extending the known distribution of the species up to 273 km to the west. Additional field studies during 1996 have yielded nineteen new county records for the species in Texas. These new reports are primarily from the Post Oak Savannah, Pineywoods, and Blackland Prairies of northeast Texas and from the southern portion of the Post Oak Savannah. The most …

Biotin Carboxyl Carrier Protein And Carboxyltransferase Subunits Of The Multi-Subunit Form Of Acetyl-Coa Carboxylase From Brassica Napus: Cloning And Analysis Of Expression During Oilseed Rape Embryogenesis, Kieran M. Elborough, Robert Winz, Ranjit K. Deka, Jennifer E. Markham, Andrew J. White, Stephen Rawsthorne, Antoni R. Slabas

Department of Biochemistry: Faculty Publications

In the oilseed rape Brassica napus there are two forms of acetyl- CoA carboxylase (ACCase). As in other dicotyledonous plants there is a type I ACCase, the single polypeptide 220 kDa form, and a type II multi-subunit complex analogous to that of Escherichia coli and Anabaena. This paper describes the cloning and characterization of a plant biotin carboxyl carrier protein (BCCP) from the type II ACCase complex that shows 61% identity/79% similarity with Anabaena BCCP at the amino acid level. Six classes of nuclear encoded oilseed rape BCCP cDNA were cloned, two of which contained the entire coding region. …

Estimation Of Variances Due To Direct And Maternal Effects For Growth Traits Of Nelore Cattle, J. P. Eler, L. Dale Van Vleck, J. B. S. Ferraz, R. B. Lobo

Department of Animal Science: Faculty Publications

Estimates of (co)variance components and genetic parameters were obtained for birth, 205-d, and 365-d weight for Nelore cattle in Brazil, using single and multiple-trait animal models. Data were from the Brazilian Zebu Breeders Association (ABCZ). Records of 27,549 calves sired by 587 bulls and raised on pasture in 57 herds were analyzed by restricted maximum likelihood fitting an animal model including direct and maternal genetic and permanent environmental effects. Single and multiple- trait analyses were carried out. Heritability estimates for direct effects were lower than previous values reported for the Nelore breed. The estimates for maternal genetic effects showed that …

What Josiah Said: Uncle Josiah's Role In Ceremony, Thomas Lynch

Department of English: Faculty Publications

Leslie Marmon Silko's novel Ceremony is probably the most thoroughly analyzed recent work of Native American literature. Much of that analysis involves the various elements that contribute to the "ceremony" that heals the main character, Tayo, including such aspects as memory, animals, ritual, traditional stories, mythological characters, and both symbolic and literal landscapes. Critics have focused especially on the role of female figures and mythological characters such as Night Swan and Ts'eh. Such an emphasis is warranted since the roles of female and mythological characters in Laguna culture are probably the two important aspects in the story least familiar-and hence …

Education And Training In Psychology And Law/Criminal Justice: Historical Foundations, Present Structures, And Future Developments, James R. P. Ogloff, Alan Tomkins, Donald N. Bersoff

Alan Tomkins Publications

Although psychology had a brief—and rather dramatic—foray into the legal system early in this century, it was only after World War II that psychology started to systematically permeate the legal system. Building on the interest psychologists and other social scientists had on the law, education and training in the areas of psychology and law/criminal justice has undergone considerable growth and development over the past two decades. The authors discuss the early developments and current models of this education and training. Implications of the increased interest and training in psychology and law/ criminal justice, and directions for future developments in these …
