Conceptual Models Of Early Diagenetic Processes: The Muddy Seafloor As An Unsteady, Batch Reactor, Robert C. Aller

Journal of Marine Research

Conceptual models of early diagenetic processes in sedimentary deposits guide interpretation and investigation of compositional patterns, elemental fluxes, and biogeochemical interactions. The ideas that sediments are open to exchange, are laterally homogeneous, and often accrete steadily upward underlie most diagenetic theory. Net accumulation rate of a deposit is thus a master variable controlling reactions, net fluxes, and sediment properties. These basic ideas and corresponding models have proved extraordinarily robust and useful. Large regions of the seafloor, however, can deviate significantly from some of the common assumptions of traditional diagenetic models, particularly along continent-ocean boundaries, where most sedimentary debris is processed. …

Passive Tracer Reconstruction As A Least-Squares Problem With A Semi-Lagrangian Constraint: An Application To Fish Eggs And Larvae, G. G. Panteleev, B. De Young, C. S. Reiss, C. T. Taggart

Journal of Marine Research

A variational, data assimilation, algorithm was developed for reconstruction of a two-dimensional, nonstationary, passive tracer field in the ocean with open boundaries and a known velocity field. The observations, spatial smoothing terms and passive tracer conservation equation were included as weak constraints. The algorithm was tested with simulated, nonstationary, pseudo-oceanographic data integrated for a 7-day period. Simulations were run to determine the robustness of the algorithm and the effect of theoretical, simulated 'sampling events,' mimicking the standard oceanographic survey. We explored the sensitivity of the reconstructed tracer fields to the distribution of the pseudo-oceanographic sampling strategy, essentially an antenna problem, …

Diffusivity And Viscosity Dependence In The Linear Thermocline, J. H. Lacasce

Journal of Marine Research

We re-visit the linear model of a thermally-driven ocean in a single hemisphere, to understand dependencies on viscosity and mixing. We focus in particular on the vertical and surface velocities. In all cases, the meridional and vertical flows are intensified near the boundaries; as a result, the overturning depends on viscosity. The two types of viscosity we examine (Rayleigh damping and diffusion with the no-slip condition) yield significantly different boundary transports. This in turn can cause large changes in the surface velocities. We observe a single-gyre surface circulation with a diffusive viscosity but two gyres with the Rayleigh. We also …

Bringing Books To A "Book-Hungry Land": Print Culture On The Dakota Prairie, Lisa Lindell

Hilton M. Briggs Library Faculty Publications

The dearth of reading material was a recurring lament in the writings and memoirs of Dakota settlers in the late nineteenth and early twentieth centuries. “I was born with a desire to read, . . . and I have never gotten over it,” declared Henry Theodore Washburn, recalling his Minnesota boyhood and homesteading years in Dakota Territory, “but there was no way in those days to gratify that desire to any great extent.”1 This lack was indeed of consequence. In the pre-electronic era, print was a primary means of obtaining information, insight, and pleasure. High rates of literacy, sharp increases …

Evaluation Of Feeding Varying Levels Of Wet Distillers Grains With Solubles As Compared To Dry Distilelrs Grains With Solubles To Finishing Steers, Kristina S. Mateo, Kent E. Tjardes, Cody L. Wright, Tanya J. Koger, Bradley D. Rops

South Dakota Beef Report, 2004

A study was conducted to determine the effects of implants and transportation on the metabolic status of feedlot steers. Steers (n = 28) were sorted by body weight, allocated into light or heavy blocks, and randomly assigned to one of two treatments. Treatments included non-implanted controls (CON) and steers implanted with Synovex Plus 70 d prior to harvest (IMP). Jugular blood and muscle biopsy samples (longissimus dorsi (LD) and semimembranosis (SM)) were collected 70 d post-implant, prior to transit. Steers were transported to Schuyler, NE, where blood and biopsy sampling was repeated. After harvest, carcass data were collected and muscle …

Bioconductor Project Working Papers

The Bioconductor project is an initiative for the collaborative creation of extensible software for computational biology and bioinformatics. We detail some of the design decisions, software paradigms and operational strategies that have allowed a small number of researchers to provide a wide variety of innovative, extensible, software solutions in a relatively short time. The use of an object oriented programming paradigm, the adoption and development of a software package system, designing by contract, distributed development and collaboration with other projects are elements of this project's success. Individually, each of these concepts are useful and important but when combined they have …

A Re-Examination Of The Taxonomic Boundaries Of Symphysia (Ericaceae), Sam. P. Vander Kloet, Jennifer L. Baltzer, Julia H. Appleby, Rodger C. Evans, Donald T. Stewart

Biology Faculty Publications

DNA sequence data were generated for the nuclear ITS region for Symphysia racemosa and for 26 additional Vaccinieae representing 12 sections in the genus Vaccinium plus one species from each of five additional segregate genera. Our focus is on the placement of S. racemosa relative to Vaccinium sensu scricto and Vaccinium sect. Oreades (represented by V. poasanum). Maximum parsimony analysis of 608 bp of nrITS region suggests that S. racemosa and V. poasanum form a well-supported clade in spite of substantial morphological divergence. Futhermore, this clade is a sister group to a clade consisting of all segregate genera examined. …

Effects Of Chronic Waterborne Nickle Exposure On Two Successive Generations Of Daphnia Magna, Eric F. Pane, James C. Mcgeer, Chris M. Wood

Biology Faculty Publications

In a 21-d chronic toxicity test in which an F₀ generation of Daphnia magna were exposed to waterborne Ni, the noobservable-effect concentration (for survival, reproduction, and growth) was 42 μg Ni L^-1, or 58% of the measured 21-d median lethal concentration (LC50) of 71.9 μg Ni L^-1 (95% confidence interval, 56.5–95.0). Chronic exposure to 85 μg Ni L^-1 caused marked decreases in survival, reproduction, and growth in F₀ animals. In the F₁ generation (daphnids born of mothers from the chronically exposed F₀ generation), animals chronically exposed to 42 μg Ni L^{-1 …}

Spatial Dynamics Of Alternative Reproductive Strategies: The Role Of Nieghbors, Vincent A. Formica, Rusty A. Gonser, Scott M. Ramsay, Elaina M. Tuttle

Biology Faculty Publications

In territorial species, the reproductive success of a male is dependent on the quality of his territory. One important component of territory quality is spatial location. High-quality territories not only should be located in areas of high food abundance and low predation, but also should be located in areas that offer optimal amounts of social interaction. Such optima might be different for individuals according to their sex, dominance, or genotype. We studied territory quality (size, vegetation structure, and placement) in a socially monogamous, polymorphic passerine, the White-throated Sparrow (Zonotrichia albicollis), in order to determine how spatial attributes contribute …

A Perfect Storm: Mercury And The Bush Administration, Rena I. Steinzor, Lisa Heinzerling

Faculty Scholarship

In December 2003, the Environmental Protection Agency (EPA) proposed a rule for mercury emissions from power plants and issued a final rule for mercury emissions from chlor-alkali facilities. Regarding power plants, EPA had previously found that mercury posed the most serious threat among the hazardous air pollutants emitted by power plants, and also that regulation of mercury from power plants was appropriate and necessary under section 112 of the Clean Air Act, which requires stringent technology-based regulation for hazardous air pollutants. Despite section 112's clear rejection of emissions trading as a compliance option, EPA has proposed to allow commercial trading …

The Cost Of Conscience: Quantifying Our Charitable Burden In An Era Of Globalization, Frank A. Pasquale

Faculty Scholarship

Development economists have long debated the proper targets for foreign aid contributions from wealthy countries. Philosophers like Peter Singer and Peter Unger now suggest that these countries' citizens have a parallel moral responsibility to tithe a portion of their income directly for the relief of the suffering of the poorest. These thinkers would prefer a systematic global redistribution of income - some public mechanism for accomplishing worldwide what the tax systems of egalitarian social democratic states accomplish. But they all realize that such global governance is unlikely to come about in any of our lifetimes. So they turn their attention …

Past Departments Faculty Publications (CELS)

We have developed a web server for the life sciences community to use to search for short repeats of DNA sequence of length between 3 and 10 000 bases within multiple species. This search employs a unique and fast hash function approach. Our system also applies information retrieval algorithms to discover knowledge of cross-species conservation of repeat sequences. Furthermore, we have incorporated a part of the Gene Ontology database into our information retrieval algorithms to broaden the coverage of the search. Our web server and tutorial can be found at http://acmes.rnet.missouri.edu

A Review Of The Physiological And Immunological Functions Of Biliary Epithelial Cells: Targets For Primary Biliary Cirrhosis, Primary Sclerosing Cholangitis And Drug-Induced Ductopenias, Chih-Te Wu, Paul A. Davis, Vellmir A. Luketic, M. Eric Gershwin

Internal Medicine Publications

Our understanding of biliary epithelial cells (BEC) in physiobiology and immunology has steadily expanded. BEC transports IgA as well as IgM into bile, synthesizes and secretes various chemokines, cytokines, and expresses adhesion molecules involved in cell interaction and signal transduction. These then suggest a myriad of potential roles for BEC in defense from invading microorganisms as well as the pathogenesis of diverse immunologically driven diseases such as primary biliary cirrhosis (PBC), graft-versus-host disease, and primary sclerosing cholangitis (PSC). Despite the progress, there still remain many areas of BEC biology that require further investigation. Most importantly, it remains to be clarified …

Palifermin For Oral Mucositis After Intensive Therapy For Hematologic Cancers, Ricardo Spielberger, Patrick Stiff, William Bensinger, Teresa Gentile, Daniel Weisdorf, Tarun Kewalramani, Thomas Shea, Saul Yanovich, Keith Hansen, Stephen Noga, John Mccarty, C. Frederick Lemaistre, Eric C. Sung, Bruce R. Blazar, Dieter Elhardt, Mon-Gy Chen, Christos Emmanouilides

Internal Medicine Publications

BACKGROUND: Oral mucositis is a complication of intensive chemotherapy and radiotherapy with no effective treatment. We tested the ability of palifermin (recombinant human keratinocyte growth factor) to decrease oral mucosal injury induced by cytotoxic therapy. METHODS: This double-blind study compared the effect of palifermin with that of a placebo on the development of oral mucositis in 212 patients with hematologic cancers; 106 patients received palifermin (60 microg per kilogram of body weight per day) and 106 received a placebo intravenously for three consecutive days immediately before the initiation of conditioning therapy (fractionated total-body irradiation plus high-dose chemotherapy) and after autologous …

The Effect Of Loading On Disturbance Sounds Of The Atlantic Croaker Micropogonius Undulatus: Air Versus Water, Michael L. Fine, Justin Schrinel, Timothy M. Cameron

Biology Publications

Physiological work on fish sound production may require exposure of the swimbladder to air, which will change its loading (radiation mass and resistance) and could affect parameters of emitted sounds. This issue was examined in Atlantic croaker Micropogonius chromis by recording sounds from the same individuals in air and water. Although sonograms appear relatively similar in both cases, pulse duration is longer because of decreased damping, and sharpness of tuning (Q factor) is higher in water. However, pulse repetition rate and dominant frequency are unaffected. With appropriate caution it is suggested that sounds recorded in air can provide a useful …

Influence Of The Pacific Decadal Oscillation On Hydrochemistry Of The Rio Grande, Usa, And Mexico, Fasong Yuan, Seiichi Miyamoto

Biological, Geological, and Environmental Faculty Publications

The hydrochemistry has been examined using the major element composition of river water at 12 gauging stations along the Rio Grande. As the Rio Grande Basin consists of two watersheds that have different hydrologic and climatic regimes, two chloride concentration records from the El Paso and Falcon Dam gauging stations have been extracted to reflect long-term variability in river chemistry of the upper and lower basins over the last 50–70 years. Both records contain decadal variability in chloride concentration but are different in nature. The chloride concentration record from the upper basin displays a distinct pattern of decadal variability similar …
