Cleaning Coliform Bacteria From Feedlot Water Tanks, David R. Smith, Todd Milton, Rodney A. Moxley, Jeff Gray, Laura Hungerford, Doreen Bailey, Tony Scott, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

Three methods of physically or chemically cleaning feedlot water tanks were tested for their ability to reduce amounts of coliform bacteria in the water and biofilm during the summer months. Draining and refilling or draining, scrubbing and refilling water tanks did not reduce coliform bacteria in water or biofilm. Coliform bacteria in water and biofilm were reduced 99% and 99.9%, respectively, after draining, scrubbing and 15 minutes of chemical disinfection with chlorine bleach and refilling. However, coliforms returned to pretreatment levels 24 to 48 hours after treatment if cattle continued to drink from the tanks.

Silas Marner And Felix Holt: Antitheses And Affinities, Ruth Harris

The George Eliot Review Online, ISSN: 2831-5375

At first sight there seems little to link Silas Mamer with Felix Halt. There are certainly contrasts, but it is harder to find similarities between a short pastoral idyll and a complex political work that looks forward to Middlemarch rather than backward to Silas Mamer. Surely there can be few links between a fairy-tale and social analysis, between a novel rich with 'Rainbow' humour and transformed 'gold' and a much darker novel laced with irony but short on both magic and jokes. Only five years separate Silas Mamer (published in April 1861) from Felix Halt (published in June 1866) but …

States Of Being In The Dark Removal And Survival In Linda Hogan's Mean Spirit, Eric Gary Anderson

Great Plains Quarterly (through 2013)

In 1990, Chickasaw poet Linda Hogan published her first novel, Mean Spirit, a well-received and yet controversial account of the Osage oil boom of the 1920s and the subsequent rash of criminal conspiracies and murders that has come to be known as the "Osage Reign of Terror."² The story she tells is often grim and violent; it returns again and again to "states of being in the dark" (44), which Hogan depicts as a wide-ranging confusion and uncertainty that afflicts many of her characters and demonstrates the period's turbulence to her readers. But the story is also resolutely …

A New Elfin Butterfly (Lycaenidae: Eumaeini) From Northern China With Comments On The Nomenclature Of Palaearctic Elfins, Kurt Johnson

The Taxonomic Report of the International Lepidoptera Survey

Ahlbergia hsui, new species, is described from two specimens recently collected in China’s Nan Shan area of endemism located along the boundary of northern China with Mongolia. In discussing the new species, the historical literature concerning Palaearctic elfin butterflies is reviewed and compared to nomenclatorial usages in D’Abrera’s widely disseminated 1993 treatment of Palaearctic butterflies; 25 errors or omissions in the latter treatment are corrected.

Historic Birds Of Lincoln's Salt Basin Wetlands And Nine-Mile Prairie, Paul A. Johnsgard

Nebraska Bird Review

The changes that have occurred in the bird life of the Lincoln area during the past century must certainly be great, but we have little evidence to document this point. There is, however, an annotated bird list from 1900 for the salt basin wetlands of western Lincoln, an area then gradually being developed for recreational use. This list was published by J. S. Hunter in the Proceedings of the First Annual Meeting of the Nebraska Ornithologists' Union (1900, 18-21). At this time, the recently impounded but still saline lake was 2 to 3 feet deep, and it covered about two …

A Summer Survey Of The Birds At Two Eastern Nebraska Wetlands, Kristine T. Phipps

Nebraska Bird Review

This study compares the avian species diversity at two eastern Nebraska wetlands that differ in their relative isolation from an urban environment. Birds were surveyed by the point Count method twice weekly at each site during June of 1998. Diversity was measured using species richness and species evenness. The percentage of bird species observed that depend on wetlands for breeding was also compared.

Results suggest that both species richness and evenness, as determined by the Shannon-Wiener index, were higher at the wetland located in a network of other marsh areas and agricultural land than at the suburban wetland. Immigration of …

A Century Of Breeding Birds In Nebraska, Jackie Canterbury, Paul A. Johnsgard

Nebraska Bird Review

With the imminent publication of the Nebraska Breeding Bird Atlas and the turning of a new millennium, it is perhaps an appropriate time to survey the state of breeding birds in Nebraska. Wayne Mollhoft's summary of the N.O.U.'s Nebraska Breeding Birds Atlasing Project (Mollhoff, 2000) provides important data bases for the latter part of the past century, and the historic overview by James Ducey (1988) offers a useful basis for judging the breeding avifauna of Nebraska from about the beginning of the century. The Biological Resources Division of the U. S. Geological Survey's (WSGSBRD) annual Breeding Bird Survey data currently …

On The Path: Pod As A Multicultural Organization, Christine A. Stanley, Matthew L. Ouellet

To Improve the Academy: A Journal of Educational Development

Since 1993, the Professional and Organizational Development Network (POD) has made an increasingly stronger commitment to becoming a multicultural organization. Poised at the entrance to a new century, it seems useful to examine the current standing of this goal in the context of the overall growth and development of POD. In this article the authors take stock of the organization’s history related to multiculturalism, discuss POD’s current organizational strengths and challenges related to models of multicultural organizational development, and offer suggestions for further progress on the path to becoming a multicultural organization.

Transforming Introductory Psychology: Trading Ownership For Student Success, Randall E. Osborne, William Browne, Susan J. Shapiro, Walter F. Wagor

To Improve the Academy: A Journal of Educational Development

As colleges struggle to maintain enrollments, many have shifted from a primary focus on recruitment of new students to an increased focus on retaining students once they begin attending the college or university. An examination of introductory courses on our campus, however, revealed significant differences between faculty perceptions of student skills and the actual skills students brought into the classroom. This prompted shifts in the manner in which we teach introductory psychology on our campus in order to enhance the skills necessary for success in survey courses and to provide a foundation of learning and thinking skills that would translate …

The Influence Of Disciplinary Differences On Consultations With Faculty, Virginia Lee

To Improve the Academy: A Journal of Educational Development

In recent years researchers have begun to investigate the nature of disciplinary differences in higher education and their implications for teaching and learning. While researchers have studied several aspects of disciplinary differences, they have given comparatively little attention to the significance of these differences for faculty development. After reviewing selective, representative studies from the literature on disciplinary differences, this paper develops a general framework for determining how the characteristics of a discipline influence the dynamics of the consulting relationship using the example of the hard sciences. It explores what kinds of discipline-specific knowledge will be important for consultants and under …

Identification Of The Transactivation Domain Of The Transcription Factor Sox-2 And An Associated Co-Activator, Tamara K. Nowling, Lance R. Johnson, Matthew S. Wiebe, Angie Rizzino

Nebraska Center for Virology: Faculty Publications

The importance of interactions between Sox and POU transcription factors in the regulation of gene expression is becoming increasingly apparent. Recently, many examples of the involvement of Sox-POU partnerships in transcription have been discovered, including a partnership between Sox-2 and Oct-3. Little is known about the mechanisms by which these factors modulate transcription. To better understand the molecular interactions involved, we mapped the location of the transactivation do-main of Sox-2. This was done in the context of its interaction with Oct-3, as well as its ability to transactivate as a fusion protein linked to the DNA-binding domain of Gal4. Both …

Sandal Types And Archaic Prehistory On The Colorado Plateau, Phil R. Geib

Department of Anthropology: Faculty Publications

Perishable artifacts provide an alternative to projectile pointsfor examining spatial patterns in Archaic material culture between northern and southern portions of the Colorado Plateau of the North American Southwest. This is so because they possess a potential great variety of specific construction and design attributes and can be directly dated to establish independent chronolo- gies of development. The analysis and dating of a collection of warp-faced plain weave sandals from Chevelon Canyon, Ari- zona demonstrates the potential utility of perishable artifacts to our understanding of prehistory. The collection provides an importantfirst sample of early Archaicfootwearfor the southern Colorado Plateau. AMS …

Effect Of Dietary Concentration Of Metabolizable Lysine On Finishing Cattle Performance, M. J. Klemesrud, Terry J. Klopfenstein, Rick Stock, Austin Lewis, D. W. Herold

Department of Animal Science: Faculty Publications

A finishing trial and a metabolism trial were conducted to determine the effect of supplemental metabolizable Lys level on finishing calf performance and to estimate the metabolizable Lys requirement of finishing calves. The finishing trial included 60 individually fed crossbred beef steer calves (237 kg; SD = 20 kg) supplemented with either incremental amounts of rumen-protected Lys and Met, or Met alone. Addition of Lys and Met improved gains and efficiencies (quadratic; P < .02) during the first 56 d. There was no response to supplemental Met alone, suggesting that supplemental Lys rather than Met was responsible for the improvement in performance. Using nonlinear analyses to compare gain relative to supplemental Lys intake, maximum gain was determined to be 2.10 kg/ d, or .27 kg/d above the zero Lys control, at a supplemental Lys intake of 2.56 g/d. Steers supplemented with 3 and 4 g of Lys had a weight advantage over the control steers of 16 kg at 56 d and 32 kg at the end of the 161- d trial. However, there were no statistical responses to Lys or Met during any periods after 56 d. During a separate metabolism trial, four steers fed the control finishing diet were slaughtered, and abomasal contents were collected for amino acid analyses. The predicted (Level 1 NRC, 1996) metabolizable protein flow to the abomasum for the control diet was 715 g/d, and the predicted Lys flow was 37.9 g/d. A supplemental Lys intake of 2.56 g/d would increase the Lys flow to 40.5 g/d. Feedlot diets low in ruminal escape protein may be deficient in metabolizable Lys, especially early in the feeding period. The metabolizable Lys requirement of steer calves gaining 2.10 kg/d is estimated to be 40.5 g/d.

Geometric Rule Learning By Clark’S Nutcrackers (Nucifraga Columbiana), Alan Kamil, Juli E. Jones

Papers in Behavior in Biological Sciences

Clark’s nutcrackers (Nucifraga columbiana) were trained to search in a location defined by its geometric relationship to 2 landmarks. Two groups were trained to search at different points along the line connecting the landmarks, and 2 groups were trained to find the 3rd point of a triangle, on the basis of either direction or distance from the landmarks. All groups learned and transferred to new interlandmark distances. However, the constant-distance group learned more slowly, searched less accurately, and showed less transfer than the other 3 groups. When tested with new orientations of the landmarks, the birds tended to …

Role Of Neurotropins In Rat Embryonic Testis Morphogenesis (Cord Formation), Elena Levine, Andrea S. Cupp, Michael K. Skinner

Department of Animal Science: Faculty Publications

The process of seminiferous cord formation is the first morphological event that differentiates a testis from an ovary and indicates male sex determination. Cord formation occurs by embryonic Day 14 (Day 0 5 plug date; E14) in the rat. A series of experiments were conducted to determine if neurotropins and their receptors are important for the process of rat embryonic cord formation. The expression of low affinity neurotropin receptor (p75/LNGFR) was determined by immunohistochemistry on sections of both testis and ovary from E13 through birth (Day 0, P0) with an antibody to p75/LNGFR. The staining for p75/ LNGFR was present …

Leg Ornamentation And The Efficacy Of Courtship Display In Four Species Of Wolf Spider (Araneae: Lycosidae), Eileen Hebets, George W. Uetz

Eileen Hebets Publications

This study used both correlative and experimental video playback methods to test the hypothesis that the secondary sexual traits of male wolf spiders act to increase the efficacy of visual courtship displays. Direct observations of courtship of several lycosid genera and a review of the literature revealed a significant association between ornamentation and visual courtship displays. This suggests that the ornamentation may be playing the role of amplifier for a visual display. To test this hypothesis, male courtship behaviors of four Schizocosa species were experimentally manipulated using video-imaging techniques. Females of species with non-visually displaying, non-ornamented males (Schizocosa duplex …

G00-1778 Field Windbreaks, James R. Brandle, Laurie Hodges

University of Nebraska-Lincoln Extension: Historical Materials

gricultural producers face many challenges as they try to balance efficient production systems with increasing environmental demands. For these systems to be successful, they must optimize the balance between inputs and final production. Field windbreaks are one way to increase yields while at the same time reducing inputs and improving both environmental quality and production efficiency. Windbreaks reduce wind speed and alter the microclimate in sheltered areas. Field windbreaks reduce wind erosion and the damage to crops caused by wind-blown soil. They improve water use efficiency, reduce risks associated with drought, and manage blowing snow.

Field windbreaks provide positive economic …

Quantitative Image Analysis Of Simian Immunodeficiency Virus Replication In Macrophages Coinfected With Mycobacterium Avium Complex, Qingsheng Li, Keith G. Mansfield, Andrew Lackner, Ashley T. Haase

Qingsheng Li Publications

Mycobacterium avium is the most frequent cause of disseminated bacterial infection in patients with human immunodeficiency virus type 1 infection and in rhesus macaques with simian immunodeficiency virus (SIV) infection. This animal model of AIDS was used to test the hypothesis that this frequent association is the result of reciprocal enhancement of replication of both microorganisms. The replication of M. avium and SIV was analyzed in lymphatic tissues obtained from rhesus macaques experimentally inoculated with SIVmac who developed or remained free of overt M. avium infection. In situ hybridization, quantitative image analysis, and staining of M. avium and of macrophages …

Ec00-1564 A Guide To Identifying Nebraska Bumble Bee Species, Marion D. Ellis, Doug Golick

University of Nebraska-Lincoln Extension: Historical Materials

For more people, pollen means allergies and bees mean stings. However, you should thank a bee, butterfly, bat, bird, or other pollinator for one out of every three bites of food you eat. There are 95 crops grown in the United States that require insect pollinators. In addition, many bee-pollinated plants provide food for wildlife, increase soil fertility, and beautify our landscapes.

This extension circular discusses the importance of bees, capturing bees, making a reference collection, identification guide, and glossary.

G00-1411 Biosecurity Basics For Cattle Operations And Good Management Practices (Gmp) For Controlling Infectious Diseases, Marilyn Buhman, Grant Dewell, Dicky D. Griffin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide introduces cattle producers to the concept of biosecurity and provides practical management recommendations for preventing and/or containing infectious disease.

Biosecurity

The goal of biosecurity is to stop transmission of disease-causing agents by preventing, minimizing or controlling cross-contamination of body fluids (feces, urine, saliva, etc.) between animals, animals to feed and animals to equipment that may directly or indirectly contact animals. Biosecurity management practices are designed to prevent the spread of disease by minimizing the movement of biologic organisms and their vectors (viruses, bacteria, rodents, flies, etc.) onto and within your operation. Biosecurity can be very difficult to maintain …
