Effects Of Glycerin In Steam Flaked Corn Feedlot Diets, Justin P. Moore, Stephanie A. Furman, Galen Erickson Erickson, Judson Vasconcelos, William A. Griffin, Todd Milton

Nebraska Beef Cattle Reports

Glycerin was fed at 0%, 3%, 6%, and 9% (DM basis) in a steam-flaked, corn-based (SFC) diet to determine the effects on performance and carcass characteristics. Glycerin linearly increased (P = 0.02) final BW, ADG linearly increased (P = 0.02), and F:G linearly decreased (P < 0.01) by 7.1%. The data  suggests glycerin can be added up to 9% inclusion to improve performance.

Economic Impact Of Sulfur Levels In Distillers Grains Diets Fed To Beef Cattle, Jhones O. Sarturi, Darrell Mark, Galen Erickson Erickson, Terry Klopfenstein, Judson Vasconcelos, Virgil R. Bremer

Nebraska Beef Cattle Reports

An economic evaluation of a growth performance study (2011 Nebraska Beef Cattle Report, pp. 62-64) comparing wet or dry distillers grains with solubles (DGS) containing varying levels of sulfur was conducted. Diets containing DGS were more profitable than the control diets containing no co-product (Control). Wet DGS showed greater profitability than Control and dry DGS diets. Sulfur content in dry DGS did not affect profitability. Profits were lowest for Control and greatest for wet DGS (0.82% S) at 30% inclusion. Low sulfur concentration in wet DGS allows shipment to feedlots further away.

Effects Of Sulfur Concentration In Distillers Grains With Solubles In Finishing Cattle Diets, Jhones O. Sarturi, Galen Erickson, Terry Klopfenstein Klopfenstein, Judson Vasconcelos, Joshua R. Benton, William A. Griffin

Nebraska Beef Cattle Reports

Effect of dietary sulfur on beef cattle fed diets containing wet or dry distillers grains with solubles (DGS) was evaluated. Sulfur concentration in DGS was either 0.82 or 1.16%. Steers (n = 120; IBW = 761 ± 75 lb) were individually fed ad libitum. Intake decreased when wet and dry 1.16% S DGS were fed. Gain decreased as wet DGS that was 1.16% S increased in the diet to 40%. Feeding wet DGS improved F:G, regardless of sulfur content. Fat thickness and HCW decreased as wet and dry 1.16% S DGS increased in the diet. High sulfur DGS reduced DMI …

Effects Of The Synthetic Antioxidants On Shelf Life Of M. Psoas Major And M. Triceps Brachii Muscles From Beef Fed Wet Distillers Grains, Lasika S. Senaratne, Chris Calkins, Judson Vasconcelos Vasconcelos, Amilton S. De Mello, M. A. Andersen, Stephanie A. Furman, Siroj Pokharel

Nebraska Beef Cattle Reports

Feedlot finishing steers (n = 483) were randomly allotted to four dry-rolled corn based diets containing 0 or 30% wet distillers grains with or without the synthetic antioxidants supplementation (ethoxyquin and tertiary butyl hydroquinone in AGRADO®PLUS). This study intended to minimize detrimental effects of feeding wet distillers grains on color and lipidoxidation of beef tenderloin and clod heart muscles during retail display by feeding a synthetic antioxidant mixture. Feeding AGRADO®PLUS significantly reduced meat discoloration and lipid oxidation.

Economic Analysis Of Supplementing Ddgs To Grazing Steers, Andrea K. Watson, Terry Klopfenstein, Galen Erickson Erickson, Darrell Mark, Walter H. Schacht

Nebraska Beef Cattle Reports

A five-year study from 2005-2009 was conducted to evaluate differences in three grazing management strategies for backgrounding calves on smooth bromegrass pastures. Economic budgets were used to calculate profit differences. Steers supplemented an average of 5.3 lb/day of distillers grains were 90 lb heavier than either of the unsupplemented groups, which resulted in increased revenue of $49.38 for supplemented steers. Land costs were the same per AUM for all treatments but were decreased on a per head basis for pastures with supplemented cattle because cattle were stocked at higher rates than the control. Profit was greatest for the supplemented steers, …

Supplementing Ddgs To Steers Grazing Smooth Bromegrass Pastures, Andrea K. Watson, William A. Griffin, Terry Klopfenstein Klopfenstein, Galen Erickson, Kelly R. Brink, Walter H. Schacht

Nebraska Beef Cattle Reports

Five years of data were summarized to evaluate cattle and pasture performance when smooth bromegrass pastures were fertilized or cattle were supplemented daily with dried distillers grains with solubles (DDGS) on nonfertilized pastures. Cattle were supplemented at 0.6% of BW for an average of 158 days. Supplemented cattle gained 0.59 lb/day more than unsupplemented cattle. As forage quality declined over the grazing season, ADG also declined but the cattle’s response to DDGS supplementation increased. Each 1 lb of DDGS supplement replaced approximately 1 lb of forage intake. Pastures with supplemented cattle had increased forage production compared to control pastures but …

Investigating Modern Communication Technologies: The Effect Of Internet-Based Communication Technologies On The Investigation Process, Matthew Simon, Jill Slay

Journal of Digital Forensics, Security and Law

Communication technologies are commonplace in modern society. For many years there were only a handful of communication technologies provided by large companies, namely the Public Switched Telephone Network (PSTN) and mobile telephony; these can be referred to as traditional communication technologies. Over the lifetime of traditional communication technologies has been little technological evolution and as such, law enforcement developed sound methods for investigating targets using them. With the advent of communication technologies that use the Internet – Internet-based or contemporary communication technologies – law enforcement are faced with many challenges. This paper discusses these challenges and their potential impact. It …

A Vitalist Perspective On Nature Journals, David M. Grant

Faculty Work

This paper argues that journals do more than simply record individual observations. Using a vitalist conception of writing – one that explicitly acknowledges writing as an ecological act – journals are formed from what literacy theorists call the “scene” of writing. This paper forwards an expanded conception of journal writing, the pedagogical uses of journals, and ways we see all writing, not just journals, as participations with the natural world.

Nonverbal Communication Among Pointe Coupee Creoles, Elsie Angelique Bergeron Gardner

LSU Doctoral Dissertations

Interactions are understood through the filter of language and culture. Because of this when people of different cultures interact, miscommunications often result. As both verbal and nonverbal aspects of communication are culturally specific, this paper examines trends in the nonverbal communication patterns of generations of Pointe Coupee Creoles undergoing language shift from Creole French in the older generation to English in the younger. The data demonstrate that nonverbal patterns are decoupled from verbal language to some extent in the degree to which they are maintained down the observable generations of Pointe Coupee Creole participants. This study analyzes videos of naturally …

Performing Toilets: Putting Matter Into Place, Danielle Dick Mcgeough

LSU Doctoral Dissertations

In this study, I place toilets and toilet practices center stage. Each chapter begins with and is compelled by a performance event in which a toilet plays a central role, such as the display of toilets in museum settings, a festival celebrating the building of public toilet blocks, and a Big Squat event, in which people gather en masse to squat collectively for one minute in recognition of the millions that lack access to toilets. By means of performance, the toilet is transferred from the backstage to center stage. Out of place, the toilet defamiliarizes and refunctions the body’s techniques, …

Development Of A Time-Dependent, Audio-Visual, Stated Choice Method Of Data Collection For Hurricane Evacuation Behavior, Ravindra Gudishala

LSU Doctoral Dissertations

Revealed preference is the traditional method to collect hurricane evacuation behavior data. However, revealed preference surveys, as they are currently administered, have the disadvantage that they are unable to collect time-sensitive and policy-sensitive data needed to test evacuation policies. In contrast, data collected from a time-dependent, stated-choice survey will allow researchers to collect not only time-sensitive and policy-sensitive data but also information that will allow testing potential new evacuation policies. However, no research has been conducted to establish the methodology of such a survey. To fill the gap, this study was conducted to develop a new time-dependent, audio-visual, stated-choice method …

Developing A Tool To Characterize The Ultradian Rhythm In Diploid Saccharomyces Cervisiae Using The Reporter Gene Green Fluorescent Protein, Imran Chiragh

LSU Master's Theses

Biological rhythms control many temporal behaviors of organism, such as the sleep cycle, hearts rhythms, seasonal animal migrations etc. Understanding these rhythms would provide insight into the temporal process of living organisms. Saccharomyces cerevisiae, a budding yeast, is an ideal model organism to study biological rhythms in eukaryotic cells because of its sequenced genome and discerned processes. By characterizing the biological rhythm in budding yeast, insight can be gained into more complex organisms. Previous studies have exhibited oscillatory behavior of oxygen consumption and determined that deletion of the GTS1 gene dissipates this rhythm. However, to further understand the specific behavior …

Mapping And Modeling Of Neglected Tropical Diseases In Brazil And Bolivia, Paula Mischler

LSU Doctoral Dissertations

Accurately defining disease distributions and calculating disease risk is an important step in the control and prevention of diseases. This study used geographical information systems and remote sensing technologies within the MaxEnt ecological niche modeling program to create predictive risk maps for leprosy and Schistosomiasis in Brazil and Chagas disease in both Brazil and Bolivia. New disease cases were compiled for leprosy, Schistosomiasis, and Chagas disease from the Brazilian ministry of Health for 2001 to 2009 and the data was stratified to a 10,000 population for each municipality. Bolivian Chagas prevalence rates were calculated from 2007 to 2009 survey data. …

An Integrated Computer-Aided Robotic System For Dental Implantation, Xiaoyan Sun, Yongki Yoon, Jiang Li, Frederic D. Mckenzie

Electrical & Computer Engineering Faculty Publications

This paper describes an integrated system for dental implantation including both preoperative planning utilizing computer-aided technology and automatic robot operation during the intra-operative stage. A novel two-step registration procedure was applied for transforming the preoperative plan to the operation of the robot, with the help of a Coordinate Measurement Machine (CMM). Experiments with a patient-specific phantom were carried out to evaluate the registration error for both position and orientation. After adopting several improvements, registration accuracy of the system was significantly improved. Sub-millimeter accuracy with the Target Registration Errors (TREs) of 0.38±0.16 mm (N=5) was achieved. The target orientation errors after …

Characterization Of Triggerable Quinones For The Development Of Enzyme-Responsive Liposomes, Maria Fabiana Mendoza

LSU Doctoral Dissertations

For decades, there has been a lot of focus on the development of new carriers for drug delivery applications. From all of the carriers, stimuli-responsive liposomes have been studied extensively, but only a handful have been enzyme-responsive liposomes. Therefore, the field of endogenous proteins as activators of liposomes is a fertile field worthy of exploration. The research described in this dissertation involves how structural changes on the quinone moiety altered their electronic properties, as well as their behavior toward the human enzyme NAD(P)H:quinone oxidoreductase type-1 (hNQO1, over expressed in certain tumor tissues), thus yielding a series of triggerable quinones to …

Caregiver Attitude, As Expressed Verbally In A Group Setting, And Its Association With Children's Attachment Security, Erin Wallace Lovett

LSU Master's Theses

Abstract The purpose of this study was to explore whether or not mothers’ attitudes, as expressed verbally in a group setting, were associated with the attachment style of the child and the insightfulness of the mother. The Circle of Security (CoS) was used as a 27 week group intervention for mothers who had become clients of a child welfare agency. Pre- and post test ratings were obtained for children’s attachment security and mothers’ insightful understanding of their children, using the Strange Situation Procedure (SSP) and the Insightfulness Assessment (IA), respectively. This study created scales for both Warmth/Empathy and Concern/Worry to …

The Role Of Ad-36 And Its E4orf-1 Protein In Modulating Glycemic Control, Emily Jane Dhurandhar

LSU Doctoral Dissertations

Current treatment strategies for Type 2 Diabetes Mellitus (T2DM) include a range of anti-diabetic drugs, supplemented by lifestyle modifications to reduce dietary fat intake and body fat. However, for their anti-diabetic action, most drugs recruit insulin signaling pathways, which are already impaired in T2DM. Also, compliance and success in achieving sustained improvements in diet or obesity over the long term is marginal. Therefore, an agent that improves diabetes independent of insulin signaling or lifestyle changes may be highly useful. Human adenovirus Ad36 offers such a model. Ad36 improves glycemic control in chow-fed mice or rats and attenuates diabetes and hepatic …

Inositol And Rhizopine Metabolism - Key Pathways For Competitive Host Nodulation In Sinorhizobium Meliloti, Petra R. A. Kohler

Dissertations

"The rhizopine concept suggests that rhizopines, which are inositol derivatives, function as nutritional mediators and play an important role in host-bacteria interactions. This thesis analyzes the hypothesis that not only rhizopines but also naturally occurring inositol isomers, such as myo-, D-chiro-, and scyllo -inositol, function as nutritional mediators in the Sinorhizobium meliloti - alfalfa nitrogenfixing symbiosis. The idhA-encoded myoinositol dehydrogenase is responsible for the first step in the degradation of myo- and D-c/z/ra-inositol. A different dehydrogenase, IolY, was found to be essential for growth with scyllo-'mositol. The iolA and iolCDEB genes were required for the further degradation of myo-, D-chiroand …

Direct Forcing And Heating Immersed Boundary- Lattice Boltzmann Method For Arterial Wall Thermography, Oluyinka Olugbenga Bamiro

Dissertations

Vulnerable atherosclerotic plaques have high probability of rupture and are characterized by non-homogenous temperature along the arterial wall. The nonhomogeneous temperature is attributed to the accumulation of heat releasing inflammatory cells in the arterial wall. Rupture of the vulnerable plaque can lead to acute coronary syndrome and sudden cardiac death. Arterial wall thermography (AWT) can be applied to detect the presence of temperature hot spots along the arterial wall by using temperature measurement devices and provide an early detection of a vulnerable atherosclerotic plaque. AWT, however, is invasive in nature.

Computational fluid and heat transport models provide a more efficient …

Evaluating The Effects Of Camera Perspective In Video Modelingfor Children With Autism: Point Of View Versus Scene Modeling, Courtney Cotter

Dissertations

Video modeling has been used effectively to teach a variety of skills to children with autism. This body of literature is characterized by a variety of procedural variations including the characteristics of the video model (e.g., self vs. other, adult vs. peer). Traditionally, most video models have been filmed using third person perspective (i.e., scene models), where the viewer is watching the actor perform in a scene. Recently, studies have successfully incorporated the use of first person perspective into video models (i.e., point of view models), where the view is directly from the actor's point of view. Currently, no studies …

The Principle Of Flickering, Laura K. Donnelly

Dissertations

The Principle of Flickering is a collection of poems that map our endeavors to survive and make sense of the flux of the world. The title poem introduces the reader to the ways the collection will approach this survival - through the poem's movement into and out of the frames of other art forms, its process of filtering a collage of voices, and its attempts to momentarily apprehend and still sources of internal and external chaos. Subsequent poems continue this engagement with survival in a variety of ways, including a lyrical study of the evolution of finches ("Darwin's Finches"), a …

Death By Boredom: The Role Of Visual Processing Theory In Written Evaluation Communication, Stephanie D. H. Evergreen

Dissertations

Evaluation reporting is an educational act and, as such, should be communicated using principles that support cognition. This study drew upon visual processing theory and theory-based graphic design principles to develop the Evaluation Report Layout Checklist intended to guide report development and support cognition in the readers of evaluation reports. It was then reviewed by an expert panel and applied by a group of raters to a set of evaluation reports obtained from the Informal Science Education evaluation website with maximum variability sampling. Results showed fairly high exact percent agreement and strong to very strong correlation with the author’s ratings. …

Neuroprotective Effects Of A Nicotinic Acetylcholine Receptor Agonist And Modulator In The Rodent Retina, Kazuhiro Iwamoto

Dissertations

The purpose of this dissertation is to assess the potential neuroprotective effect of an alpha7 nAChR agonist, PNU-282987, and modulator, PNU-120596, in an in vitro model of excitotoxicity and an in vivo model of acute glaucoma. In in vitro studies, retinas obtained from Long Evans rats were cultured using various concentrations of the PNU compounds to analyze neuroprotection against glutamate-induced excitotoxicity. After 3 days in culture, RGCs were identified using an antibody against Thy 1.1, visualized using a fluorescent dye and quantified. In culture, glutamate significantly decreased the number of RGCs. However, if either PNU compound was introduced before the …

Psychometric Properties Of Diagnostic Assessment Instrumentsfor Autism Spectrum Disorders In A Community Sample Aged 2 Through 17 Years, Sheryl Lozowski-Sullivan

Dissertations

Recent estimates of the incidence and prevalence of autism spectrum disorders (ASDs) indicate substantial increases over the past 20 years (Centers for Disease Control and Prevention, 2009; Fombonne, 2009; Matson & Kozlowski, 2011; Schreibman & Koegel, 2005; Wing & Porter, 2002), in part because of the availability of significantly improved diagnostic assessment instruments (Lord & Corsello, 2005; Schreibman, 2005). In highly structured research settings, some of these diagnostic instruments correlate well with each other; however, few studies have examined the relation between these diagnostic tools in traditional clinical practice (Mazefsky & Oswald, 2006; South et al, 2002). This study examined …
