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 …

Economic Analysis Of Supplementing Ddgs To Grazing Steers, Andrea K. Watson, Terry Klopfenstein, Galen Erickson Erickson, Darrell Mark, Walter H. Schacht Jan 2011

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 Jan 2011

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 Jan 2011

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 Jan 2011

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 Jan 2011

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 …

Comparison Of Thermally Pasteurized And Ultrasonically Pasteurized Blueberry Juice (Vaccinium Corymbosum) And An Investigation Of Blueberry Juice Effect On Lipid Oxidation During Microencapsulation Of Poly-Unsaturated Fish Oils, Fathima Waheeda Mohideen

LSU Master's Theses

Blueberries have received considerable attention due to their content of health promoting compounds such as polyphenols and anthocyanins. Thermal pasteurization (TP) is known to cause degradation of anthocyanins and juice color. Microencapsulation, particularly with incorporation of blueberry antioxidants, can improve the stability of menhaden (MO) and salmon (SO) fish oils rich in omega-3 fatty acids. The objectives of this research were to study the effect of TP and continuous ultrasonication processing on the microbiological, chemical and physical properties of blueberry juice (BJ) and to determine the effect of BJ on MO and SO lipid oxidation during microencapsulation. Fresh blueberries were …

Performing Toilets: Putting Matter Into Place, Danielle Dick Mcgeough Jan 2011

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, …

Myth, Method And Masturbation: The Hysteria Of Woman's Sexuality, A One-Person Play, Josephine Hall Jan 2011

Myth, Method And Masturbation: The Hysteria Of Woman's Sexuality, A One-Person Play, Josephine Hall

LSU Master's Theses

The assigned task was to create a one-person play of approximately 20 – 45 minutes in length. There were no other guidelines to follow. Having never performed a solo play, I found the assignment somewhat daunting. My first challenge was to overcome my basic dislike of solo performances. However, during the process I found new appreciation for such works. I was rather overwhelmed when trying to find a suitable topic for my piece until I came across an on-line article entitled “Vaginas with teeth – and other sexual myths”. This spurred me to create the one-person play Myth, Method and …

Climate Change Displacement And Global Governance: A Case Study Of Three Intergovernmental Organizations And The Conflict Between The Member States And Bureaucracy, Andrea C. S. Berringer Jan 2011

Climate Change Displacement And Global Governance: A Case Study Of Three Intergovernmental Organizations And The Conflict Between The Member States And Bureaucracy, Andrea C. S. Berringer

LSU Doctoral Dissertations

Climate change is a topic most often broached by environmental scientists and activists and its effects are discussed in terms of animal populations and atmospheric events. However, its direct effect on human life is yet to garner such attention. A changing climate will affect how people are able to use their environment, if at all. Sea level rise and desertification will force a shift in human habitation. How the world seeks to deal with this shift is yet to be seen. The global governance of climate change-induced displacement is currently at the stage of ad hoc development. Legal and conceptual …

Development Of A Time-Dependent, Audio-Visual, Stated Choice Method Of Data Collection For Hurricane Evacuation Behavior, Ravindra Gudishala Jan 2011

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 Jan 2011

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 …

"We Live In A Used World": Cultural Geographies Of American Garage Sales, Gentry Powell Hanks Jan 2011

"We Live In A Used World": Cultural Geographies Of American Garage Sales, Gentry Powell Hanks

LSU Master's Theses

This thesis seeks to understand the emotional geographies of American garage sales, which I argue are liminal. Through a methodology of narrative surveys (open-ended questionnaires), mental maps, participant-observation, and interviews, I make the case that garage sales, through absent and/or present items, narratives, and exchanged histories, can reveal much in terms of identity, values, and cultural practices. These archives on the margins hold stories, artifacts, and performances of a distant or near past, giving geographers an innovative lens through which to explore the intricacies of materiality, place, and representation. This thesis provides a range of theoretical and practical perspectives on …

Proteomic Analysis Of The Blood Of Alligator Mississippiensis, Lancia Nadinia Fallen Darville-Bowleg Jan 2011

Proteomic Analysis Of The Blood Of Alligator Mississippiensis, Lancia Nadinia Fallen Darville-Bowleg

LSU Doctoral Dissertations

My research focus was to investigate alligator blood using mass spectrometry-based proteomics methods to understand their innate immune systems. The first goal was to sequence peptides and proteins from the blood serum and leukocytes using tandem mass spectrometry and de novo sequencing. The second goal was to determine the function of these biological molecules and their relationship to the immune system. One- and two-dimensional gel electrophoresis was used to separate proteins from alligator leukocytes, which were enzymatically digested. The peptides were measured using reversed phase nano-high performance liquid chromatography coupled with tandem mass spectrometry (nano-HPLC-MS/MS) followed with de novo sequencing. …

The Tick Response To Rickettsial Dissemination During Typical And Atypical Rickettsial Infection, Piyanate Sunyakumthorn Jan 2011

The Tick Response To Rickettsial Dissemination During Typical And Atypical Rickettsial Infection, Piyanate Sunyakumthorn

LSU Doctoral Dissertations

Ticks are the only disease vectors for spotted fever group (SFG) Rickettsia which are obligate intracellular bacteria belonging to the genus Rickettsia. In nature, ticks maintain the infection of SFG Rickettsia via vertical and horizontal transmission. However, the prevalence of rickettsial transmission is limited to certain species of ticks, and this limitation is known as a specific tick/Rickettsia relationship. Due to the continuous increase of tick-borne rickettsial disease cases in the United States, which contrasts with very low prevalence of Rickettsia in tick vectors, the study of vector competence of tick to Rickettsia is needed in order to understand the …

Calcium-Dependent Mechanisms In The Chicken Retina, Merve Tekmen Jan 2011

Calcium-Dependent Mechanisms In The Chicken Retina, Merve Tekmen

LSU Doctoral Dissertations

Multiple classes of retinal amacrine cells use L-type Ca2+ channels to mediate synaptic transmission. I have used whole cell voltage clamp recordings from primary cultures of amacrine cells to investigate the regulation of these channels. In this study, I show that inhibiting mitochondrial calcium uptake (MCU) caused a reversible reduction in the Ca2+ current amplitude. Replacing external Ca2+ with Ba2+ minimized the effects of blocking MCU indicating that the Ca2+ influx is the primary source of the inhibition. With 1,2-bis-(o-aminophenonxy)ethane-N,N,N’,N’-tetraacetic acid (BAPTA) in the recording pipette, MCU inhibition caused an increase in the current amplitude indicating that the fast buffering …

Spatial Ecology Of Adult Spotted Seatrout, Cynoscion Nebulosus, In Louisiana Coastal Waters, Jody Lynn Callihan Jan 2011

Spatial Ecology Of Adult Spotted Seatrout, Cynoscion Nebulosus, In Louisiana Coastal Waters, Jody Lynn Callihan

LSU Doctoral Dissertations

Spotted seatrout, Cynoscion nebulosus, are common in estuaries and coastal waters of the south Atlantic and Gulf of Mexico and are of considerable recreational and economic importance. Still, the spatial ecology of this species is under-studied and poorly resolved, especially in Louisiana waters. To address this important knowledge gap, I examined the movements, distribution, and habitat use of adult spotted seatrout in coastal Louisiana primarily using high-resolution acoustic telemetry and secondarily, conventional tagging (mark-recapture) data. At the largest spatial scale investigated, I found that adults exhibited a high degree of estuarine fidelity and rarely undertook large-scale movements in excess of …

Formation And Stabilization Of Combustion-Generated Environmentally Persistent Free Radicals On Transition Metal Oxides Supported On Silica, Eric Warren Pimentel Vejerano Jan 2011

Formation And Stabilization Of Combustion-Generated Environmentally Persistent Free Radicals On Transition Metal Oxides Supported On Silica, Eric Warren Pimentel Vejerano

LSU Doctoral Dissertations

The formation of environmentally persistent free radicals in combustion system was investigated from chemisorptions of chlorine- and hydroxy-substituted benzenes on transition metal oxide surface under post-combustion conditions. This manuscript reports the formation of EPFRs on silica particles containing 5% Fe(III)2O3, Ni(II)O, and Zn(II)O. The EPFRs are formed by the chemisorption of substituted aromatic molecular adsorbates on the metal cation center followed by electron transfer from the adsorbate to the metal ion at temperatures from 150 to 400 oC. Depending on the nature of the adsorbate and the temperature, two organic EPFRs were formed: a phenoxyl-type radical, which has a lower …

Characterization Of Triggerable Quinones For The Development Of Enzyme-Responsive Liposomes, Maria Fabiana Mendoza Jan 2011

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 …
