Nitrogen Fertilizer Rate And Weather Dictate Nutritive Value Of Fall Stockpiled Bermudagrass, John A. Guretzky, Jeff Ball, Billy J. Cook

Department of Agronomy and Horticulture: Faculty Publications

Stockpiled bermudagrass [Cynodon dactylon (L.) Pers. ‘Midland’] as a standing forage may meet nutritional needs of beef cows during winter. Our objective was to evaluate accumulation and nutritive value of fall stockpiled bermudagrass in response to N fertilization rate, N application date, and harvest date. Research was conducted near Burneyville, OK from 2000 to 2003. Fertilization rates included 0, 50, 100, and 150 lb N per acre applied on 15 August, 1 September, 15 September, 1 October, and 15 October. Forage accumulation was measured 10 days after the first killing frost; thereafter, crude protein (CP), acid detergent fiber (ADF), …

A Versatile Assay For The Identification Of Rna Silencing Suppressors Based On Complementation Of Viral Movement, Jason G. Powers, Tim L. Sit, Feng Qu, T. Jack Morris, Kook-Hyung Kim, Steven A. Lommel

Nebraska Center for Virology: Faculty Publications

The cell-to-cell movement of Turnip crinkle virus (TCV) in Nicotiana benthamiana requires the presence of its coat protein (CP), a known suppressor of RNA silencing. RNA transcripts of a TCV construct containing a reporter gene (green fluorescent protein) (TCV-sGFP) in place of the CP open reading frame generated foci of three to five cells. TCV CP delivered in trans by Agrobacterium tumefaciens infiltration potentiated movement of TCV-sGFP and increased foci diameter, on average, by a factor of four. Deletion of the TCV movement proteins in TCV-sGFP (construct TCVΔ92-sGFP) abolished the movement complementation ability of TCV CP. Other known suppressors of …

The World Social Forum, A Globalisation From Below?, Pleyers

Societies Without Borders

The author argues that the World Social Forum (WSF), the annual meeting held by members of the anti-globalization or alter-globalization movement, came out as an initiative from committed intellectuals and cosmopolitan activists. He outlines the emergence process of an influential and well-connected activist cosmopolitan elite within the alter-globalization movement. He then focuses on consequences of the divide between hyper mobile, globe-trotting leaders and local and regional grassroots activists.

The Impact Of Recurring Natural Disasters On Chronic Poverty, Anwar

Societies Without Borders

Natural disasters disorder the existing everyday normative practices. The magnitude of any disaster creates risk and vulnerability in different ways that apply to different groups. The consequences of material and non-material risk and vulnerability downgrade the existing social structure and social order of the society, which reflects in the process of the cultural system, demographic scenario, social process, socialization, good governance and women empowerment. I use the concept "chronic poverty" as a condition created by intergenerational socio-economic and cultural processes. My analysis encompasses the interrelationship and interdependency between unequal access to resources and recovery process on the context of disaster …

Loose Lips Sink Attorney-Client Ships: Unintended Technological Disclosure Of Confidential Communications, Bill Piatt, Paula Dewitte

Faculty Articles

Attorneys have an ethical obligation to protect their clients' confidences. Attorneys are required to consider what possibilities exist for unintended disclosure through technology, how they can adapt to these new realities to fulfill obligations of effective representation and maintenance of client trust and confidences, and how attorneys can employ a tripartite approach to information security to better protect client information. Under the general obligation to maintain confidentiality as set out in Rule 1.6 of the Model Rules of Professional Conduct, attorneys are precluded from revealing “information relating to the representation of a client.”

The legal profession has started to educate …

Archaeoparasitology, Karl J. Reinhard, Adauto Araújo

Department of Anthropology: Faculty Publications

Parasites are the major cause of ill health and early death in the world today. Malaria, sleeping sickness, amoebic dysentery, and hookworm infection are examples of commonplace parasitic diseases that are endemic in most parts of the world (see Health, Healing, and Disease). They were significant threats in prehistory, especially in cultures whose social complexity outstripped the development of effective sanitation, hygiene, and germ theory awareness.

Burials: Dietary Sampling Methods, Karl J. Reinhard, Vaughn M. Bryant, Jr.

Department of Anthropology: Faculty Publications

The analysis of burials for botanical and zoological remains evidence of diet is a proven method of nondestructive analysis in the mortuary setting. The value of such analyses is directly dependent on sampling strategies that must include a number of control samples.

Time-Averaged Deposits And Multi-Temporal Processes In The Wyoming Basin, Intermontane North America: A Preliminary Consideration Of Land Tenure In Terms Of Occupation Frequency And Integration., Luann Wandsnider

Department of Anthropology: Faculty Publications

Archaeological time perspectivism encompasses the notion that archaeological deposits are formed through the operation of processes occurring at a variety of tempos over the short, medium, and long term (Bailey 1981, 1983, 1987, 2007, this volume). The processes involved may be behavioral, social, formational, organizational, or evolutionary, to name a few. Through their operation, material consequences may be immediate, lagged, or follow after some threshold is breached. Moreover, interaction may occur among and between different processes, depending on whether they operate at approximately the same scale (Bailey 1983; Fletcher 1995).

A corollary of the first statement is that different archaeological …

Time In Archaeology: An Introduction, Simon J. Holdaway, Luann Wandsnider

Department of Anthropology: Faculty Publications

Lifeway reconstruction is listed as one of the objectives of "World Prehistory," the ubiquitous course taught in universities and colleges the world over (e.g., Fagan 1995:8). It complements well the other subdisciplines of anthropology, at least for beginning anthropology students, offering them a familiar approach to foreign material: if cultural anthropologists study the behavior of present-day (or at least near-to-present-day) peoples, then archaeologists may be expected to deal with peoples' behavior from the past. Certainly, some archaeologists study the past aided by textual records, and some cultural anthropologists are interested in past historical experience. But this overlap only enhances the …

A Proposed Role For Vegf Isoforms In Sex-Specific Vasculature Development In The Gonad, Rebecca Bott, Debra T. Clopton, Andrea S. Cupp

Department of Animal Science: Faculty Publications

Many scientists have expended efforts to determine what regulates development of an indifferent gonad into either a testis or ovary. Expression of Sry and upregulation of Sox9 are factors that initiate formation of the testis-specific pathway to allow for both sex-specific vasculature and seminiferous cord formation. Migration of mesonephric precursors of peritubular myoid cells and endothelial cells into the differentiating testis is a critical step in formation of both of these structures. Furthermore, these events appear to be initiated downstream from Sry expression. Sertoli cell secretion of growth factors acts to attract these mesonephric cells. One hypothesis is that a …

Effect Of Supplemental Energy Source And Frequency On Growing Calf Performance, T. W. Loy, Terry Klopfenstein, Galen E. Erickson, C. N. Macken, J. C. Macdonald

Department of Animal Science: Faculty Publications

Crossbred heifers (n = 120; 265 kg, SD = 37) were fed individually (84 d) to determine the effect of supplement type, concentration, and frequency on intake and performance and to estimate the energy value of dry distillers grains plus solubles (DDGS) in a high-forage diet. Treatments were arranged in a 3 × 2 × 2 factorial, with 3 supplements, 2 concentrations, and 2 frequencies of supplementation. Supplements including dry-rolled corn (DRC), DRC with corn gluten meal (DRC + CGM), and DDGS were fed at 0.21% (LOW) or 0.81% (HIGH) of BW daily and were provided daily (DAILY) or 3 …

Tenderness, Sensory, And Color Attributes Of Two Muscles From The M. Quadriceps Femoris When Fabricated Using A Modified Hot-Boning Technique, B. E. Jenschke, B. J. Swedberg, Chris R. Calkins

Department of Animal Science: Faculty Publications

The M. quadriceps femoris from USDA Choice (n = 12) and USDA Select (n = 12) carcasses were fabricated traditionally (COLD) or innovatively (HOT), in which the seams it shares with the top round and bottom round were separated prerigor to evaluate positional and locational effects on Warner-Bratzler shear force (WBSF), sensory attributes, and objective color. At slaughter, paired USDA Choice and USDA Select carcasses were alternately assigned either the HOT or COLD treatment. At 48 h postslaughter, subprimals were removed, vacuum-packaged, and aged for an additional 5 d. After aging, the M. quadriceps femoris was cut into 2.54-cm-thick steaks …

The Effect Of Feeding Dried Distillers Grains Plus Solubles On Milk Production And Excretion Of Urinary Purine Derivatives, B. N. Janicek, P. J. Kononoff, A. M. Gehman, P. H. Doane

Department of Animal Science: Faculty Publications

Two studies were performed to evaluate the effects of dried distillers grains with solubles (DDGS) on the lactational performance of dairy cows. The intent of experiment 1 was to evaluate the effects of feeding increasing concentrations of DDGS on the feed intake and production of Holstein dairy cows. Twenty multiparous Holstein cows averaging 76 ± 24 d in milk and 638 ± 68 kg of body weight were randomly assigned to one of five 4 × 4 Latin squares. During each of the 28-d periods, cows were offered 1 of 4 diets: 1) control, 0% DDGS, 2) 10% DDGS, 3) …

A New Heat Load Index For Feedlot Cattle, J. B. Gaughan, Terry L. Mader, S. M. Holt, A. Lisle

Department of Animal Science: Faculty Publications

The ability to predict the effects of extreme climatic variables on livestock is important in terms of welfare and performance. An index combining temperature and humidity (THI) has been used for more than 4 decades to assess heat stress in cattle. However, the THI does not include important climatic variables such as solar load and wind speed (WS, m/s). Likewise, it does not include management factors (the effect of shade) or animal factors (genotype differences). Over 8 summers, a total of 11,669 Bos taurus steers, 2,344 B. taurus crossbred steers, 2,142 B. taurus × Bos indicus steers, and 1,595 B. …

Department of Animal Science: Faculty Publications

The Cornell-Penn-Miner (CPM) Dairy is an applied mathematical nutrition model that computes dairy cattle requirements and the supply of energy and nutrients based on characteristics of the animal, the environment and the physicochemical composition of the feeds under diverse production scenarios. The CPM Dairy was designed as a steady-state model to use rates of degradation of feed carbohydrate and protein and the rate of passage to estimate the extent of ruminal fermentation, microbial growth, and intestinal digestibility of carbohydrate and protein fractions in computing energy and protein post-rumen absorption, and the supply of metabolizable energy and protein to the animal. …

Effect Of Intensive Winter Management, Partial Season Grazing, And Sorting On Performance And Economics Of A Long Yearling Steer Production System, J. D. Folmer, W. A. Griffin, C. N. Macken, M. P. Blackford, T. J. Klopfenstein, G. E. Erickson

Department of Animal Science: Faculty Publications

A 2-yr study (200 steers/yr) was conducted to evaluate effects of grazing management and sorting by BW at feedlot entry on performance and economics of yearling steers. At receiving, steers (247 ± 21 kg) were randomly allotted to 1 of 2 treatments: low (0.75 kg/d, NORM) or high (0.90 kg/d, INT) gains during backgrounding. After wintering, NORM and INT grazed native range for 128 and 78 d, respectively. At feedlot entry, steers were randomly allotted to 1 of 2 treatments: sorted by BW (25% heavy, 50% medium, or 25% light; SORT) or unsorted (UNSORT). Heavy, medium, light, and UNSORT steers …

Effect Of Feeding Das-59122-7 Corn Grain And Nontransgenic Corn Grain To Individually Fed Finishing Steers, T. J. Huls, G. E. Erickson, T. J. Klopfenstein, Matt K. Luebbe, K. J. Vander Pol, D. W. Rice, B. Smith, M. Hinds, F. Owens, M. Liebergesell

Department of Animal Science: Faculty Publications

An experiment was conducted to evaluate feeding transgenic corn containing the cry34Ab1 and cry35Ab1 genes from a Bacillus thuringiensis strain and the phosphinothricin acetyltransferase (pat) gene from Streptomyces viridochromogenes to finishing cattle compared with nontransgenic corn. Expression of the cry34Ab1 and cry35Ab1 genes confers resistance to corn rootworms, and the pat gene confers tolerance to herbicides containing glufosinate-ammonium. Sixty crossbred steers (396 kg) were individually fed either transgenic corn (DAS-59122-7; 59122), a near-isogenic, nontransgenic control (Control), and a conventional, nontransgenic corn for 109 d to evaluate nutritional equivalency (20 steers/treatment). The corn was coarsely rolled (geometric mean diameter = 4,200 …

Different Methods Of Selecting Animals For Genotyping To Maximize The Amount Of Genetic Information Known In The Population, Matthew L. Spangler, R. L. Sapp, J. Keith Bertrand, M. D. Macneil, R. Rekaya

Department of Animal Science: Faculty Publications

It is possible to predict genotypes of some individuals based on genotypes of relatives. Different methods of sampling individuals to be genotyped from populations were evaluated using simulation. Simulated pedigrees included 5,000 animals and were assigned genotypes based on assumed allelic frequencies for a SNP (favorable/unfavorable) of 0.3/0.7, 0.5/0.5, and 0.8/0.2. A field data pedigree (29,101 animals) and a research pedigree (8,688 animals) were used to test selected methods using simulated genotypes with allelic frequencies of 0.3/0.7 and 0.5/0.5. For the simulated pedigrees, known and unknown allelic frequencies were assumed. The methods used included random sampling, selection of males, and …

Changes In Connectedness Over Time In Alternative Sheep Sire Referencing Schemes, L. A. Kuehn, D. R. Notter, G. J. Nieuwhof, R. M. Lewis

Department of Animal Science: Faculty Publications

A statistic to measure the level of connectedness achieved among flocks would help producers to assess the risk of comparing EBV of animals from different flocks. The objectives of this research were to evaluate the pattern of change over time in selected connectedness measures and to determine how effectively these measures quantify the level of risk due to potential bias in EBV comparisons across production units. Connectedness was evaluated using simulated sheep populations, with connections established using sire referencing schemes (SRS). Pedigree and performance data for a single trait with a within-flock heritability of 0.25 were simulated (50 replications) for …

Assessing Genetic Gain, Inbreeding, And Bias Attributable To Different Flock Genetic Means In Alternative Sheep Sire Referencing Schemes, L. A. Kuehn, D. R. Notter, R. M. Lewis

Department of Animal Science: Faculty Publications

Flocks participating in sire referencing schemes can achieve greater genetic gains than those achievable by within-flock selection. However, requirements for joining these schemes can be prohibitive to some producers. The objectives of this study were to determine whether less restrictive schemes or schemes of shorter duration could achieve rates of gain and reduce inbreeding as efficiently as continuous sire referencing schemes (SRS) and to investigate whether bias from different genetic means could be reduced by these alternative schemes. Pedigree and performance data for a single trait with a within-flock heritability of 0.25 were simulated (50 replications) for 15 flocks with …

Dissection Of A Qtl Hotspot On Mouse Distal Chromosome 1 That Modulates Neurobehavioral Phenotypes And Gene Expression, Khyobeni Mozhui, Daniel C. Bastiaansen, Thomas Schikorski, Xusheng Wang, Lu Lu, Robert W. Williams

Department of Animal Science: Faculty Publications

A remarkably diverse set of traits maps to a region on mouse distal chromosome 1 (Chr 1) that corresponds to human Chr 1q21–q23. This region is highly enriched in quantitative trait loci (QTLs) that control neural and behavioral phenotypes, including motor behavior, escape latency, emotionality, seizure susceptibility (Szs1), and responses to ethanol, caffeine, pentobarbital, and haloperidol. This region also controls the expression of a remarkably large number of genes, including genes that are associated with some of the classical traits that map to distal Chr 1 (e.g., seizure susceptibility). Here, we ask whether this QTL-rich region on Chr 1 …

Glutamate Signaling Proteins And Tyrosine Hydroxylase In The Locus Coeruleus Of Alcoholics, Beata Karolewicz, Laurel Johnson, Katalin Szebeni, Craig A. Stockmeier, Gregory A. Ordway

ETSU Faculty Works

It has been postulated that alcoholism is associated with abnormalities in glutamatergic neurotransmission. This study examined the density of glutamate NMDA receptor subunits and its associated proteins in the noradrenergic locus coeruleus (LC) in deceased alcoholic subjects. Our previous research indicated that the NMDA receptor in the human LC is composed of obligatory NR1 and regulatory NR2C subunits. At synapses, NMDA receptors are stabilized through interactions with postsynaptic density protein (PSD-95). PSD-95 provides structural and functional coupling of the NMDA receptor with neuronal nitric oxide synthase (nNOS), an intracellular mediator of NMDA receptor activation. LC tissue was obtained from 10 …
