The Relationship Between Mosquito Abundance And Rice Field Density In The Republic Of Korea, Erin E. Richards, Penny Masuoka, David Brett-Major, Matthew Smith, Terry A. Klein, Heung Chul Kim, Assaf Anyamba, John Grieco

Journal Articles: Epidemiology

BACKGROUND: Japanese encephalitis virus (JEV), the causative agent of Japanese encephalitis (JE), is endemic to the Republic of Korea (ROK) where unvaccinated United States (U.S.) military Service members, civilians and family members are stationed. The primary vector of the JEV in the ROK is Culex tritaeniorhynchus. The ecological relationship between Culex spp. and rice fields has been studied extensively; rice fields have been shown to increase the prevalence of Cx. tritaeniorhynchus. This research was conducted to determine if the quantification of rice field land cover surrounding U.S. military installations in the ROK should be used as a parameter in a …

The Role Of The Ca2+-Dependent Protein Kinase, Camk-Ii, In Heart And Kidney Development In The Zebrafish, Danio Rerio, Sarah Rothschild

Theses and Dissertations

Ca2+/calmodulin-dependent protein kinase type II (CaMK-II) is a multifunctional serine/threonine kinase that is ubiquitously expressed throughout the lifespan of metazoans. Mammals encode four genes (α, β, γ, δ) that generate over forty splice-variants. CaMK-II is important in a myriad of functions, including ion channel regulation, cell-cycle progression, and long term potentiation. In adults, alterations in activation of CaMK-II induce cardiac arrhythmias and heart failure. Developmental roles for CaMK-II are not as well understood since mouse knockouts are embryonic lethal. Therefore the identification of other vertebrate CaMK-II genes will add to our understanding of development. Zebrafish encode seven catalytically active CaMK-II …

Role Of Oxidative Reactive Species And Antioxidants In Metabolism And Transport Of Therapeutic Drugs, Svetlana Verenich

Theses and Dissertations

Oxidative stress (OS) is a frequent complication of various disease conditions such as Alzheimer’s and Parkinson’s disease, atherosclerosis, preeclampsia, rheumatoid arthritis, diabetes including gestational diabetes, etc. OS is defined as an imbalance between the production of reactive species and the ability of an organism to detoxify the reactive intermediates and repair the damage. As a result of OS, the excess of reactive species such as oxygen superoxide (O2-), hydroxyl radical (OH), peroxynitrite (ONOO−), 4-hydroxynonenal (4HNE), etc., have a tendency to react with nearby proteins/nucleic acids/lipids changing their functionality or inactivating them completely. The organism has many ways to protect itself …

Autotaxin: A Regulator Of Oligodendrocyte Differentiation, Larra Yuelling

Theses and Dissertations

In order for oligodendrocyte progenitor cells (OPCs) to differentiate into fully mature, myelinating oligodendrocytes, they must be specified at the correct times and undergo coordinated changes in both gene expression and morphology. As oligodendrocytes differentiate, they transition from a bipolar morphology into a morphology characterized by a complex network of multiple processes, which will eventually generate membranous structures necessary for myelination of axonal segments. As changes are observed in cellular morphology, oligodendrocytes also undergo changes in their gene expression profile and express genes necessary for both early and later stages of development such as olig1 and myelin basic protein (mbp), …

Repressive Bodies, Transgressive Bodies : Dracula And The Feminine, Sharon Kostopoulos

Theses : Honours

Dracula has long been associated with the repressive qualities of Victorian society and the oppression of the emerging New Woman. However, taking into account that the novel is part of the gothic genre, a genre which endeavours to infringe the social boundaries in any given era, this thesis will demonstrate an equally visible and potent transgressive feminine element playing out in Dracula. Using Michel Foucault's idea of discourse to show how subjects are generated, the novel can be seen as facilitating both productive and repressive ideas of femininity. Power, as it operates through discourse, tends to produce its own resistance, …

Reeling In Big Phish With A Deep Md5 Net, Brad Wardman, Gary Warner, Heather Mccalley, Sarah Turner, Anthony Skjellum

Journal of Digital Forensics, Security and Law

Phishing continues to grow as phishers discover new exploits and attack vectors for hosting malicious content; the traditional response using takedowns and blacklists does not appear to impede phishers significantly. A handful of law enforcement projects — for example the FBI's Digital PhishNet and the Internet Crime and Complaint Center (ic3.gov) — have demonstrated that they can collect phishing data in substantial volumes, but these collections have not yet resulted in a significant decline in criminal phishing activity. In this paper, a new system is demonstrated for prioritizing investigative resources to help reduce the time and effort expended examining this …

Bayesmotif: De Novo Protein Sorting Motif Discovery From Impure Datasets, Jianjun Hu, F. Zhang

Faculty Publications

Background

Protein sorting is the process that newly synthesized proteins are transported to their target locations within or outside of the cell. This process is precisely regulated by protein sorting signals in different forms. A major category of sorting signals are amino acid sub-sequences usually located at the N-terminals or C-terminals of protein sequences. Genome-wide experimental identification of protein sorting signals is extremely time-consuming and costly. Effective computational algorithms for de novo discovery of protein sorting signals is needed to improve the understanding of protein sorting mechanisms.

Methods

We formulated the protein sorting motif discovery problem as a classification problem …

Increased Weed Diversity, Density And Above-Ground Biomass In Long-Term Organic Crop Rotations, Samuel E. Wortman, John L. Lindquist, Milton J. Haar, Charles A. Francis

Department of Agronomy and Horticulture: Faculty Publications

While weed management is consistently a top priority among farmers, there is also growing concern for the conservation of biodiversity. Maintaining diverse weed communities below bioeconomic thresholds may provide ecosystem services for the crop and the surrounding ecosystem. This study was conducted to determine if weed diversity, density and biomass differ within and among organic and conventional crop rotations. In 2007 and 2008, we sampled weed communities in four long-term crop rotations near Mead, Nebraska, United States using seedbank analyses (elutriation and greenhouse emergence) and above-ground biomass sampling. Two conventional crop rotations consisted of a corn (Zea mays) …

Production Decisions And Time Allocation: A Guide To Data Collection, Raymond B. Hames

Department of Anthropology: Faculty Publications

In this chapter I deal with methods for collecting behavioral and economic data on productive inputs and outputs. Any attempt at the collection of quantitative data requires that the researcher should ideally have prior knowledge of the full range of economic activities and perform preliminary evaluations of the accuracy of data collection procedures and coding schemes. This will prevent false starts, increase cross-cultural comparability, and lead to a more systematic account of activities. Whenever possible, I encourage researchers to rely on observational data as a kind of gold standard: it produces data amenable to sophisticated quantitative analysis, is crucial for …

Lipid And Ndf Analysis Of Ethanol Byproduct Feedstuffs, Virgil R. Bremer, Crystal D. Buckner, Andrew W. Brown, Timothy P. Carr, Ruth M. Diedrichsen, Galen E. Erickson, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

A newly developed biphasic feed lipid extraction procedure has increased accuracy relative to Goldfisch ether extraction, especially for condensed corn distillers solubles samples. A pre-NDF fat extraction must be completed prior to analyzing high fat feeds for NDF. Corn should be ground through a 1-mm screen on a Tecator Cyclotec sample mill to accurately determine corn NDF content.

Metabolism Characteristics Of Feedlot Diets Containing Different Fat Sources, Virgil R. Bremer, Kelsey Rolfe, Crystal D. Buckner, Galen E. Erickson, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

A metabolism trial was conducted to evaluate the effects of dietary fat source on the metabolism characteristics of feedlot steers fed 8.5% fat (7% fatty acids) diets. Steers fed condensed corn distillers solubles (CCDS) had lower average pH and greater DM digestibility than those fed corn oil, tallow, or WDGS. Steers fed CCDS also had greater fat and fatty acid digestibility than corn and corn oil fed steers and greater NDF digestibility than corn oil or tallow fed steers. Although CCDS fat is similar to corn oil, the two feeds are digested differently. The omasal fatty acid profile of steers …

Factors Associated With Feed Intake Of Angus Steers, Marco G. Dib, Jeremy F. Taylor, Robert D. Schnabel, L. Dale Van Vleck

Nebraska Beef Cattle Reports

Estimates of variance components and heritability of average daily feed intake (AFI) and residual feed intake (RFI) were obtained using an animal model. Data were from 475 Angus steers raised and fed at the Circle A Ranch (Iberia, Mo.). Pedigree files were provided by the American Angus Association. Estimates of heritability after adjustment for average daily gain (ADG) were 0.56 and 0.60 for AFI and RFI. Selection for feed intake (FI) should be effective if FI records are available. Feed intake needs to be adjusted for age and weight on test. Carcass measurements (fat thickness and rib eye muscle area) …

Effect Of Calving Season And Wintering System On Cow Performance, William A. Griffin, Don C. Adams, Leslie Aaron Stalker, Richard N. Funston, Jacqueline A. Musgrave, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

Four years of data from three different calving seasons and two different cow wintering systems were evaluated utilizing 218 cows/year. Cows calved in spring, summer, or fall and were wintered on native Sandhills range or cornstalks. Calving season affected cow body weight (BW) and body condition score (BCS) throughout the production year; calving in the fall reduced number of calves weaned per cow. No differences were observed between cows wintered on Sandhills range and those wintered on cornstalks.

Acid Marination For Tenderness Enhancement Of The Beef Bottom Round, Jeremy H. Hinkle, Chris R. Calkins, Amilton S. De Mello Jr., Lasika S. Senaratne, Siroj Pokharel

Nebraska Beef Cattle Reports

Two experiments were conducted to evaluate acid marination to enhance tenderness of the beef bottom round (m. biceps femoris). Both experiments consisted of 3 acid types (acetic, lactic, and citric) and two concentrations (0.1 and 0.5 M in Exp. 1; 0.75 and 1.5 M in Exp. 2). There were no effects of acid marination on beef tenderness in Exp. 1, although lightness (L*) increased and redness decreased from 0 to 8 hours post-marination. Acetic and lactic acid (0.75 or 1.5 M) improved shear force values above those achieved by citric acid. Both lightness and redness permanently decreased in Exp. 2. …

Tympanic Temperature Profiles Of Confined Beef Cattle, Terry L. Mader, Leslie J. Johnson

Nebraska Beef Cattle Reports

Angus crossbred yearling steers were used to evaluate tympanic temperature (TT) profile of cattle displaying high, moderate, or low levels of heat stress. Data indicate cattle that do not adequately cool down at night are prone to greater body temperatures during a subsequent hot day. Cattle that are prone to displaying moderate levels of heat stress but can cool at night will maintain average tympanic temperatures at or near those of cattle that tend to consistently maintain lower peak tympanic temperatures. In addition, during cooler and moderately hot periods, cattle change TT in a stair-step or incremental pattern, while under …

Supplementing Wet Distillers Grains Mixed With Low Quality Forage To Grazing Cow/Calf Pairs, Brandon L. Nuttelman, William A. Griffin, Terry J. Klopfenstein, Walter H. Schacht, Leslie Aaron Stalker, Jacqueline A. Musgrave, Jerry D. Volesky

Nebraska Beef Cattle Reports

Two studies were conducted over two years during the summer grazing season to determine the effect of grass intake when grazing cow/calf pairs were supplemented wet distillers grains (WDGS) with low quality forage. In 2007, a mixture of 45% WDGS and 55% grass hay was fed. In 2008, three blends of 50:50, 60:40, and 70:30 WDGS and wheat straw were fed. Supplemented cows and calves outgained non-supplemented groups in 2007. There were no differences in animal performance during 2008. Grazed forage intake was reduced by supplementing WDGS mixed with wheat straw without negatively affecting animal performance.

Comparison Of Feeding Wet Distillers Grains In A Bunk Or On The Ground To Cattle Grazing Native Sandhills Winter Range, Jacqueline A. Musgrave, Leslie Aaron Stalker, Matthew C. Stockton, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

Two experiments determined the effects of feeding wet distillers grains with solubles (WDGS), either on the ground or in a bunk, to cattle grazing native Sandhills winter range. In Exp. 1, frequency of supplementation had no effect on cow body weight (BW) or body condition score (BCS). BCS and BW of cows fed in a bunk were improved compared to cows fed on the ground. In Exp. 2, steers fed in a bunk had greater average daily gain than steers fed on the ground. Feeding WDGS on the ground resulted in 13-20% waste and cost between$0.03 and $0.045 per day.

Extending Grazing In Heifer Development Systems Decreases Cost Without Compromising Production, Daniel M. Larson, Andrea S. Cupp, Richard N. Funston

Nebraska Beef Cattle Reports

Three experiments compared heifer development in the dry lot, grazing either dormant winter range or corn crop residue. Grazing corn residue may reduce pre-breeding gain and in doing so increase age at puberty. Compared to dry lot development, grazing corn residue reduced AI pregnancy rate, but final pregnancy rate was similar for both development tsystems. Calf production and rebreeding efficiency were not affected by the development system. However, grazing corn residue during heifer development reduced cost compared to development in the dry lot. Developing heifers by grazing dormant forage does not affect final pregnancy rate and reduces cost, improving the …

Feeding Fiber From Wet Corn Gluten Feed And Corn Silage In Feedlot Diets Containing Wet Distillers Grains Plus Solubles, Amy R. Rich, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Joshua R. Benton

Nebraska Beef Cattle Reports

A feedlot experiment evaluated the effect of increasing fiber in distillers grains diets on ADG, F:G, and nutrient mass balance. The treatments consisted of 1) 30% modified distillers grains plus solubles, no roughage (MDGS), and 2) 30% modified distillers grains plus solubles, 30% wet corn gluten feed, and 15% corn silage (MDGS+fiber). The remainder of each diet consisted of a 1:1 ratio of high moisture corn and dry rolled corn and 5% supplement. Feeding MDGS+fiber increased (P < 80.02) ADG, DMI, and HCW; however, it did not improve F:G compared to MDGS. By increasing the fiber content of the diet, more organic matter (OM) and N remained in the manure. Percentage N loss was not different between dietary treatments; however, amount of N lost increased with MDGS + fiber due to the greater N intake and excretion.

Effects Of Using Wet Distillers Grains With Solubles To Adapt Cattle To Finishing Diets On Feed Intake, Ruminal Ph, And Ruminal Hydrogen Sulfide Concentration, Kelsey Rolfe, Galen E. Erickson, Terry J. Klopfenstein, Judson Vasconcelos

Nebraska Beef Cattle Reports

An adaptation strategy with wet distillers grains with solubles (WDGS) fed at decreasing levels (87.5 to 35%) was compared to a traditional grain adaptation with decreasing forage (45 to 7.5%) when adapting steers to a common finishing diet. Traditionally adapted steers had higher intake in steps one through three compared to steers adapted with distillers grains. However, DMI was not different between the two adaptation systems in step four, or when steers were on the finishing diet. Ruminal pH was higher for traditionally adapted steers compared to steers adapted to distillers grains in adaptation diets two and three. Ruminal hydrogen …

Routine Hedging Of Fed Cattle Sales Price For Calf-Fed And Yearling Production Systems, Rebecca M. Small, Darrell R. Mark, Terry J. Klopfenstein Klopfenstein

Nebraska Beef Cattle Reports

Short futures hedges in the Chicago Mercantile Exchange live cattle futures contract were evaluated to determine if profit variability could be decreased for calf-fed and yearling production systems. Results indicated standard deviations of calf-fed profits could be reduced by $35-$47/head through routine hedging. Routine hedges of yearling cattle, however, resulted in profit declining nearly $50/head, but profit variability also decreased.

Multiple Antimicrobial Interventions For The Control Of Escherichia Coli O157:H7 In Very Small Beef Processing Facilities, Benjamin J. Williams, Dennis E. Burson, Bryce M. Gerlach Gerlach, Ace F. Van Dewalle, Harshavardhan Thippareddi

Nebraska Beef Cattle Reports

One-hundred and fifty beef carcasses from 3 very small beef processing plants were sponge sampled for aerobic plate count, generic E. coli, coliforms, Enterobacteriaceae, and E. coli O157:H7 before and after carcass intervention strategies. The control (C) treatment consisted of one 3% lactic acid (LA) wash applied at the end of slaughter, just prior to chilling. The multiple (M) intervention treatment received a 3% LA wash prior to evisceration, a hot water wash after carcass splitting and trimming, and a final LA wash just prior to chilling. The M treatment showed greater log reductions throughout the slaughter process prior to …

Structural Analysis Of Affect In The Pre-Purchase Context, Rosemary R. Seva, Henry Been Lirn Duh, Martin G. Helander

DLSU Business & Economics Review

Previous studies on consumption related affect did not identify specific components in the pre-purchase context. This article reviewed theoretical bases of affect and its relationship to product judgment and determined the components and structure of pre-purchase affect. Field studies were conducted to gather an initial list of affect experienced before purchasing “highinvolvement” products. An initial list of 94 pre-purchase affect was identified and trimmed down to 18 after further statistical analysis. A second study was conducted to determine the structure of the pre-purchase emotion set (PES) derived from the first study. Multidimensional scaling was used and four clusters of emotion …
