Comparison Of The Effectiveness Of Alternative Ferrate (Vi) Synthesis Formulas As Disinfectants For Wastewater And River Water, Rachelle Ginart

Electronic Theses and Dissertations

Ferrate (VI) has been studied as an alternative chemical to disinfect water and wastewater in recent years. The disinfection effectiveness of two different wet oxidation ferrate (VI) synthesis formulas in wastewater and Econlockhatchee River water was evaluated. Ferrate (VI) is synthesized by addition of ferric chloride to a mixture of sodium hydroxide and calcium hypochlorite (refer to U.S. Patent 6,790,429). One ferrate (VI) synthesis formula uses below the stoichiometric requirement of hypochlorite (Low Chlorine Formula) while the other ferrate (VI) synthesis formula uses more than the stoichiometric requirement of hypochlorite (Standard Chlorine Formula). For applications requiring low chlorine residual effluent …

Turning Stones Of Hope Into Boulders Of Resistance: The First And Last Task Of Social Justice Curriculum, Scholarship, And Practice, Derek W. Black

Faculty Publications

The most important and intangible aspect of teaching and practicing social justice law is retaining the hope that our efforts can translate into progressive results. At times, professors’ approaches to the subject of social justice tend toward pessimism that can have unintended negative effects on students. Thus, this Article calls on social justice professors to explicitly teach hope and, moreover, to produce practical scholarship on pressing legal issues that will help students keep hope once they leave school. This Article begins by exploring the theme of hope in John O. Calmore’s scholarship and how it interrelates with his project of …

Filtering, Piracy Surveillance And Disobedience , Sonia K. Katyal

Faculty Scholarship

There has always been a cyclical relationship between the prevention of piracy and the protection of civil liberties. While civil liberties advocates previously warned about the aggressive nature of copyright protection initiatives, more recently, a number of major players in the music industry have eventually ceded to less direct forms of control over consumer behavior. As more aggressive forms of consumer control, like litigation, have receded, we have also seen a rise in more passive forms of consumer surveillance. Moreover, even as technology has developed more perfect means for filtering and surveillance over online piracy, a number of major players …

Fli-1 In B Cell Proliferation And Systemic Lupus Erythematosus, Sarah Gail Bradshaw

MUSC Theses and Dissertations

PBMC from patients with SLE and splenic lymphocytes from murine models of SLE demonstrate increased expression of the ETS transcription factor Fli-1. Transgenic overexpression of Fli-1 in normal mice leads to SLE-like disease. These findings suggest investigation of the role of Fli-1 in SLE may elucidate etiology of the disease and potential therapies. The MRL/lpr mouse is a model of SLE exhibiting increased lymphocytic expression of Fli-1. Reduction of Fli-1 expression by heterozygousity at the Fli-1 locus (Fli1+/-) results in decreased auto- and alloantibodies, proteinuria, and renal pathology; and drastically decreased mortality. Disruption of the C-terminal transactivation domain (Fli1ΔCTA/ΔCTA) reduces …

Full-Cycle Assessment Of Critical Thinking In An Ethics And Science Course, Jennifer Blue, Beverley Taylor, Jan Yarrison-Rice

International Journal for the Scholarship of Teaching & Learning

Enhancing critical thinking skills for undergraduate students is important across the curriculum and between disciplines. We report on a method of improving critical thinking skills, which was studied through an Ethics and Science First-Year Seminar course. We used full cycle assessment over a three-year period to assess students’ development and to modify the course teaching and assignments with the goal of increasing student development of critical thinking skills. Data were obtained from student writing throughout the semester during each offering. Modest, but significant, overall gains of ~0.7 on a 4 point scale are reported between early and midterm assignments in …

Display Of An Inedible Prop As A Signal Of Aggression? Adaptive Significance Of Leaf-Display By The Turquoise-Browed Motmot, Eumomota Superciliosa, Troy G. Murphy

Biology Faculty Research

The incorporation of an inedible object (prop) into a behavioral display is rare among birds. Only four avian taxa have been reported to display with a prop, and in all studied species, prop use has been found to play a role in mate acquisition. However, little is known about the context and adaptive significance of prop use by the motmots. Both male and female motmots perform a leaf-display, whereby a leaf is held horizontally in the tip of the bill for an extended period. I collected observational data on leaf-display by the turquoise-browed motmots (Eumomota superciliosa) to investigate …

Performance And Economics Of Two Calf Wintering Systems, William A. Griffin, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

Two wintering systems, cornstalk grazing plus 5 lb/head/day of wet corn gluten feed and cornstalk grazing followed by dry lot where steers were fed hay and supplemented 5 lb/head/day of wet corn gluten feed were evaluated. There were no differences in daily gain, or final body weight for either system. While there were no statistical differences in cost of gain, break-even, or profitability, economics numerically favored steers grazing cornstalks alone.

The Cattle Price Cycle: Revisited Again, Matthew C. Stockton, Roger K. Wilson, Leslie Aaron Stalker

Nebraska Beef Cattle Reports

New analyses and statistical techniques were applied to historical data to determine if time, changes in production technology, and business structure changes in the sector had altered the length of the cattle price cycle. Most recent work has been done the cattle inventory cycle. The price cycle was shown to be remarkably constant, despite many changes in the industry. Feeder cattle prices have continued to follow an approximate 10-year cycle. The model demonstrates the consistency of the cycle but shows that unexplained price variations occur suggesting caution be employed when it is used as a marketing guide.

Evaluation Of Calf-Fed And Long Yearling Production With Increasing Corn Price, William A. Griffin, Terry J. Klopfenstein, Galen E. Erickson, Darrell R. Mark

Nebraska Beef Cattle Reports

An economic comparison of calf-fed and long-yearling production was conducted to determine the impact of increasing corn price on steer profitability. Corn prices of $2.50, $3.50, and $4.50/bu were used. With increasing corn price, feeder prices were assumed to decrease which decreased initial cost more for yearlings than calf-feds. Profitability of yearlings versus calf-feds increased $4-6 for each $1/bu increase in corn price.

Effect Of Backgrounding Gain, Grazing Length And Dry Distillers Grain Consumption On Performance And Carcass Traits Of June Born Cattle, J. Alan Taylor, Leslie Aaron Stalker, Terry J. Klopfenstein, Don C. Adams, William A. Griffin

Nebraska Beef Cattle Reports

June-born cattle backgrounded at a lower rate during the winter were unable to fully compensate during sum¬mer grazing for restricted gain during backgrounding. Increased gain during backgrounding resulted in cattle being heavier for all market periods. The higher cost associated with increased gain was offset by heavier sale weights. Cattle grazing meadow regrowth had improved feedlot performance and heavier finished weight. Backgrounding cattle grazing winter range supplemented with DDG costs less than backgrounding cattle in a drylot. Supplementing with DDG during summer grazing decreased forage intake and increased gain, with 1.8 lb/head/day being more cost effective than 5 lb/head/day.

Vaccination For Escherichia Coli O157:H7 In Feedlot Cattle, Rodney A. Moxley, David R. Smith, Karen Hansen, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Dragan Rogan

Nebraska Beef Cattle Reports

A clinical trial conducted during the summer of 2006 evaluated the effects of two- and three-dose regimens of an Escherichia coli O157 vaccine product on the probability of detecting E. coli O157:H7 in feces and on colonization of the terminal rectum. The three-dose regimen significantly reduced the probability for cattle to shed E. coli O157:H7 in feces by 63% compared to placebo treated cattle. A dose-effect was demonstrated because a two-dose regimen of the vaccine product was intermediate in effect. These results are consistent with previous estimates of vaccine efficacy against fecal shedding and agree with our previous finding that …

Factors That Influence Consumers’ Overall Sensory Acceptance Of Strip Steaks, Jennie M. Hodgen, Bethany M. Johnston, Blaine E. Jenschke, Kent M. Eskridge, Chris R. Calkins

Nebraska Beef Cattle Reports

Multivariate analysis was used to determine demographic, knowledge, habits, and sensory preferences that influence a consumer’s opinion about the acceptability of strip steaks from corn-fed, barley-fed, and grass-fed beef. Even with all the additional information, most consumers’ final opinions about specific types of steaks are based on how they perceive the flavor, tenderness, and juiciness of the beef.

Mapping Tenderness Of The Serratus Ventralis, Lauren M. Grimes, Chris R. Calkins

Nebraska Beef Cattle Reports

Serratus ventralis muscles from eight USDA Choice and eight Select carcasses were obtained. Samples were enhanced with a marination or left as controls, then blade tenderized once as whole muscles and cut into steaks. Enhanced steaks were then blade tenderized individually. Odd-numbered steaks were cooked, cored, and sheared for Warner-Bratzler (WBS) shear force determination. Tenderness was found to vary sporadically throughout the muscle with the posterior end being the most tender, regardless of grade. Enhanced samples produced lower WBS values than controls. The serratus ventralis does respond to enhancement techniques, and steaks could especially be fabricated from the posterior end.

Analysis Of Veal Shoulder Muscles For Chemical Attributes, Gary A. Sullivan, Chris R. Calkins, D. Dwain Johnson, Brian G. Sap

Nebraska Beef Cattle Reports

The value of wholesale veal cuts varies; the rack, loin, and leg demand a premium price, while the shoulder brings little more per pound than the live animal. This study characterized the chemical properties of muscles from the veal shoulder for the potential to upgrade their value. The m. infraspinatus and m. rhomboideus fell in the intermediate or desirable groups for all traits. All nine muscles show promise in the ability to increase value.

Tenderness, Sensory, And Color Attributes Of Two Muscles From The Beef Knuckle, Blaine E. Jenschke, Brittni J. Swedberg, Chris R. Calkins

Nebraska Beef Cattle Reports

Twelve USDA Choice and twelve USDA Select quadriceps muscles were fabricated traditionally or the seams it shares with the top and bottom round were separated pre-rigor to test the effect of pre-fabrication on tenderness, sensory, and color. Results from this study indicated treatment had minimal effects on quality attributes. The proximal portions of the knuckle were more tender, lighter in color, and more red when compared to the distal portions, although all were reasonably tender. Pre-fabrication can be conducted without detriment to product quality.

Characteristics Of Beef Finished On Wet Distillers Grains With Varying Types And Levels Of Roughage, Blaine E. Jenschke, Joshua R. Benton, Chris R. Calkins, Timothy P. Carr, Kent M. Eskridge, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

Beef knuckles (n = 160) were obtained from source-verified cattle finished on 30% wet distillers grains plus solubles enriched with varying levels of alfalfa hay, corn silage, or corn stalks based on NDF. Our objectives were to determine if roughage inclusion, in conjunction with wet distillers grains plus solubles and cattle location affects beef flavor. Data from this study indicate type and level of roughage inclusion and cattle location have minimal effects on fatty acid profiles and sensory properties of the M. Rectus femoris. However, individual fatty acids of subcutaneous and intramuscular fat were significantly correlated with liver-like off flavor.

Influence Of Feeding Wet Distillers Grains On Fatty Acid Composition Of Beef, Amilton S. De Mello Jr., Blaine E. Jenschke, Chris R. Calkins

Nebraska Beef Cattle Reports

Ribeye slices (M. Longissimus thoracis) were obtained from 94 calf-fed, crossbred steers. Animals were randomly allocated into three groups and finished for 133 days with corn-based diets and varying levels of wet distillers grains plus solubles (0%, 15% or 30%, DM Basis). No treatment differences were found for total lipid, unsaturated, and saturated fatty acids. However, values of 18:2 9t,12t, total polyunsaturated fatty acids, total amount of trans fatty acids, conjugated linoleic acid and the omega 6:omega 3 ratio were elevated. It appears that wet distillers grains plus solubles finishing diets alters the fatty acid profile of beef.

Wet Distillers Grains Plus Solubles Affect Lipid Oxidation And Objective Color Of Beef Steaks, Amilton S. De Mello Jr., Blaine E. Jenschke, Chris R. Calkins

Nebraska Beef Cattle Reports

Strip loins (M. Longissimus lum¬borum), tenderloins (M. Psoas major) and top blades (M. Infraspinatus) from 48 calf-fed, crossbred steer carcasses, were used to test the effects of wet distillers grains plus solubles finishing diets on beef shelf life. After 7-day display, inclusion of wet distillers grains plus solubles in the diet caused higher levels of oxidation on top blades and strip loins and negative effects on color of top blade and tenderloin steaks after 3 days of retail display.

Effects Of Wet Distillers Grains Finishing Diets On Fat Content And Marbling Score In Steers, Amilton S. De Mello Jr., Chris R. Calkins

Nebraska Beef Cattle Reports

Ninety-four, calf-fed, crossbred steers were randomly allocated to three finishing diets consisting of different amounts of wet distillers grains plus solubles (0%, 15% or 30%, DM basis). Steers were fed for 133 days to test the relationship between marbling score and fat content, as well as effects on marbling texture and marbling distribution. Results of this research suggest that feeding up to 30% of wet distillers grains plus solubles has no detrimental effects on marbling in beef.

Evaluation Of Methods For Dry Matter Determination Of Ethanol Byproducts, Mallorie F. Wilken, Galen E. Erickson, Joshua R. Benton, Crystal D. Buckner, Terry J. Klopfenstein, Kip Karges, Matt Gibson

Nebraska Beef Cattle Reports

Traditional wet distillers grains plus solubles, modified distillers grains, Dakota Bran Cake, and distillers solubles were sampled and replicates tested using oven drying (n = 8) at 105°C and 60°C, vacuum oven drying (n = 3) and toluene distillation process (n = 8). Two replicates were evaluated using Karl Fischer titration. Oven drying was compared to toluene distillation as the standard. Oven drying at 60°C for 24 hours resulted in the same DM (P > 0.10) as toluene distillation for wet byproducts.

Ruminal Methane Production Following The Replacement Of Dietary Corn With Dried Distillers Grains, Eric J. Behlke, Tim G. Sanderson, Terry J. Klopfenstein, Jess L. Miner

Nebraska Beef Cattle Reports

Methane production was measured following the replacement of corn with DDGS in vitro and also after the simultaneous replacement of corn and corn oil with DDGS (for 30% of the diet) in vivo. In vitro substitution of corn with DDGS increased the amount of methane produced per milligram of DM digested. Likewise, in vivo methane production was increased by 44% when corn and corn oil were replaced with DDGS. The greater energy value of DDGS relative to corn in a concentrate-based diet is not due to decreased methanogenesis.

Microbial Characteristics, Microbial Nitrogen Flow, And Urinary Purine Derivative Excretion In Steers Fed At Two Levels Of Feed Intake, Grant I. Crawford, Matt K. Luebbe, Joshua R. Benton, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

Ruminally and duodenally fistulated Holstein steers were fed at 40% and 85% of ad-libitum intake. Microbial purine:N ratio did not differ between intake levels, which makes estimating microbial protein easier in production or experimental settings. Urinary purine derivatives (PD):creatinine (PD:C) ratio and microbial CP flow estimated from the duodenum increased with the higher feeding level. Urinary PD:C and duodenal purine flow were related, suggesting that urinary PD:C ratio can be used to estimate relative differences in microbial CP flow.
