Novel Strategies To Develop Better Brucellosis Vaccines Using Brucella Abortus Rb51 And B. Neotomae, Neha Dabral

Open Access Dissertations

The genus Brucella consists of Gram-negative, facultative intracellular coccobacilli that can cause chronic infections in several mammals. Brucella spp. can exhibit a smooth or rough phenotype; smooth Brucella spp. contain a surface-exposed O-polysaccharide in their cell wall structure while the rough Brucella spp. are devoid of the O-polysaccharide. Acquired immunity against Brucella infection is primarily cell-mediated and involves both CD4+ T cells and CD8+ T cell responses. However, antibodies to the O-polysaccharide also play a role in enhancing the protection against infections by virulent Brucella species in some hosts. B. abortus strain RB51 is a stable rough attenuated mutant which …

Evaluation Of A Novel Feedstuff For Horses, Catherine Whitehouse

Theses and Dissertations--Animal and Food Sciences

Determining digestibility of feed ingredients is a challenge. While forage type feeds may be fed as the sole dietary component, concentrates cannot. To determine the apparent digestibility of these ingredients a by difference method can be utilized. The study was conducted to investigate the nutritional value of corn germ dehydrated (AAFCO 48.32) for horses in comparison to two processed corns commonly fed to horses. The second objective was to compare total tract digestibility of the treatments to determine differences in digestibility of the various fiber fractions due to added concentrate and to use the difference method to determine nutrient digestibility …

Rheological, Foam, And Physical Properties Of Low Sucrose Meringue And Angel Food Cake Formulated With Non-Nutritive Sweeteners And Polydextrose, Kevin J. O'Niones

Theses and Dissertations--Animal and Food Sciences

The object of this research was to determine if an acceptable angel food cake alternative could be produced that had reduced calories and sucrose content. This was accomplished through replacing sucrose in meringue, angel food cake batter, and baked angel food cakes with polydextrose and either sucralose, acesulfame-K, or Rebaudioside A at different replacement levels (25, 50, 75, 100%). Meringue and cake batter properties were measured using rheological techniques. Baked angel food cakes were analyzed based on height, weight loss, moisture content, color, and TPA analysis. With meringue batter, 100% sucrose replacement was unacceptable since undissolved polydextrose made analyzing and …

Gestational Form Of Supplemental Selenium (Se) Affects Steroidogenic Gene Expression In The Newborn Calf Testis, Stefani R. Garbacik

Theses and Dissertations--Animal and Food Sciences

Selenium (Se) is an important trace mineral in the diet of cattle. Our objective was to determine whether the form of supplemental Se fed to the dam would affect the expression of genes regulating steroidogenesis in the newborn testis. Twenty-four Angus-cross cows were assigned randomly (n=8) to individual ad libitum access of a mineral mix containing 35 ppm of Se supplied as sodium selenite (inorganic, ISe; Prince Se), Sel-Plex (organic, OSe; Sel-Plex, Alltech) or a 50/50 mix of ISe/OSe (MIX) 4 months prior to breeding and throughout gestation. All male calves were castrated within 2 days of birth and total …

Modeling Digestibility And Rate Of Passage In Horses, Tayler L. Hansen

Theses and Dissertations--Animal and Food Sciences

Horses consume large amounts of fiber in their diet, which may affect digestibility and digesta rate of passage. The objective of these studies was to assess the effects of diet composition on digestibility and rate of passage in horses using mathematical models. Using previously published data, forage dry matter digestibility (DMD) was related to forage neutral detergent fiber (NDF) concentrations and crude protein (CP) concentrations (DMD = 66.1178 – 0.3410*NDF + 0.6356*CP, DM basis; P < 0.001). In a second experiment, horses were fed diets formulated to have high fiber (HF, n= 3; NDF = 55.3%, CP = 11.8%) or low fiber (LF, n = 3; NDF = 40.5%, CP = 13.3%) concentrations. The LF treatment had greater DM, organic matter, and gross energy digestibilities (P < 0.05), whereas the HF treatment had greater NDF digestibility (P < 0.05). Mathematical models were useful to determine mean retention time (MRT) and there were no differences between model MRT and algebraic MRT, or treatment. Some compartmental parameters were different between treatments (P < 0.05), indicating that dietary fiber may alter some components of digesta passage in horses.

An Assessment Of Two Feed Additives To Improve Feed Utilization In Pigs, Amanda Shaw Thomas

Theses and Dissertations--Animal and Food Sciences

Three experiments were conducted to assess the efficacy of including selected feed additives in the diet of weaning and grow-finish pigs. Experiment 1 utilized 24 crossbred grow-finish pigs and measured the effect of added EHY on DM, N, and energy digestibility. There were no differences in DM, Energy, and N digestibility between diets 1 through 4. Experiment 2 utilized a total of 36 crossbred pigs [18 barrows, 18 gilts] in order to determine if preference would be shown when presented with naturally-contaminated corn. There were three dietary comparisons, Control vs Diet 2 (Comparison 1), Control vs Diet 4 (Comparison 2), …

The Impact Of Dual Chamber Cow Waterbeds As A Freestall Base, Barbara Alice Wadsworth

Theses and Dissertations--Animal and Food Sciences

The objectives of this research were to compare lying time, milk yield, rumination time, hock score, stall cleanliness, and stall temperature for 97 cows (Holsteins (n = 71), Jerseys (n = 10), and crossbreds (n = 16)) housed on Dual Chamber Cow Waterbeds™ (DCCW, Advanced Comfort Technology, Reedsburg, WI) or conventional rubber mattresses (MAT). This study was conducted at the University of Kentucky Coldstream Research Dairy Farm from January 18, 2012 to May 3, 2013. Lying times were longer (P < 0.01) for cows housed on the DCCW (10:32 ± 0:13) compared to cows housed on the MAT (9:47 ± 0:15). Milk yield was not different (P ≥ 0.05) between cows housed on the DCCW or MAT. Rumination times were greater (P = 0.03) for cows housed on MAT (6:44 ± 0:08) compared to cows housed on DCCW (6:29 ± 0:08). Hock scores were lesser (P = 0.02) for cows housed on DCCW (1.86 ± 0.03) compared to cows housed on MAT (1.97 ± 0.04). Stall cleanliness was not different (P ≥ 0.05) between the DCCW and the MAT. The DCCW stall temperature was warmer (P < 0.01) (13.29 ± 0.21 ⁰C) than the MAT (10.52 ± 0.21 ⁰C).

The Acoustic Emissions Produced By Escherichia Coli During The Growth Cycle, Traci Jane Cox

Theses and Dissertations--Animal and Food Sciences

The objective of this study was to determine if acoustic emissions (AE) generated by three strains of Escherichia Coli (5024-parent strain, 8279-mutant strain and 8279-random/unrelated strain) could be used to differentiate each strain during their growth cycle. An acoustic sensor with an operating range of 35 kHz-100 kHz was inserted into the growth vessel and attached to a selected channel to capture AE data. The growth vessel was loaded with 60 ml of tryptic soy broth (TSB) (0.25% fructose) media with alginate (1.1%) or without alginate and inoculated with 1% (10⁸ CFU/ml) of an E. coli strain. The growth …

Compost Bedded Pack Barns For Dairy Cattle: Bedding Performance And Mastitis As Compared To Sand Freestalls, Elizabeth A. Eckelkamp

Theses and Dissertations--Animal and Food Sciences

Lameness and mastitis are the two most costly diseases in the dairy industry. Reduction of these diseases through housing and management is beneficial. Compost bedded pack (CBP) and sand freestall barns were compared in a long-term, on-farm study to assess the effect of housing on each disease. Another research objective was to evaluate the effects of ambient weather conditions on moisture and 20 cm internal temperature of CBP. Compost bedded pack moisture, C:N ratio, and internal temperature effects on cleanliness, mastitis, and bedding bacterial counts were also considered. The last research objective was to evaluate the economics of bedding material …

Our Pathway To God: Drawn By Desire, Thomas Ryan

Theology Papers and Journal Articles

[...]we should take seriously Jesus' words to the blind Bartimaeus: 'What do you want me to do for you?' This question is emblematic of the human quest for meaning. [...]the indwelling Spirit gives a new energy and power to humanity to realize the plans of God. [...]the Risen Jesus' presence in his community points to a reconciliation of the unresolved tension of the inner/outer dimensions of experience, of the relationship between the personal and the communal and a, finally, clarification of what is authentic and inauthentic in a way of life centered on God revealed in Jesus.

Twilight: The Unveiling Of Victims, Stalking, And Domestic Violence, Susan L. Brody

Cardozo Journal of Equal Rights & Social Justice

The article critically examines the Twilight saga, arguing that it romanticizes stalking, domestic violence, and controlling relationships by framing them as acts of love. Bella, the protagonist, is portrayed as a victim who idealizes these harmful behaviors, making her a problematic role model for young women. The series, while a fantasy, perpetuates dangerous stereotypes and normalizes violence in relationships, influencing works like Fifty Shades of Grey and impacting young audiences' perceptions of love and control.

In Vitro Culture Of Bovine Preantral Follicles: A Review, Valdevane R Araújo, Melba O Gastal, José R Figueiredo, Eduardo L Gastal

Peer-reviewed Articles

Preantral follicles are the majority of the ovarian follicle population and their use as a source of homogeneous oocytes for bovine reproductive biotechnologies could result in a substantial advance in this field. However, while in other species embryos and offspring have been produced, in bovine species the results have been limited to the follicular activation of small (primordial) preantral follicles and formation of early antral follicles from large (secondary) preantral follicles after in vitro culture. Therefore, this review will highlight the basic aspects of bovine folliculogenesis by focusing on preantral follicles, the methods of harvesting preantral follicles, the main results …

Currently, the Convention has 96 signatories and only one ratified party, the United States.

The Forkhead Transcription Factor, Foxp3: A Critical Role In Male Fertility In Mice., Jake S Jasurda, Deborah O Jung, Erin D Froeter, David B Schwartz, Torin D Hopkins, Corrie L Farris, Stacey Mcgee, Prema Narayan, Buffy S Ellsworth

Articles

Fertility is dependent on the hypothalamic-pituitary-gonadal axis. Each component of this axis is essential for normal reproductive function. Mice with a mutation in the forkhead transcription factor gene, Foxp3, exhibit autoimmunity and infertility. We have previously shown that Foxp3 mutant mice have significantly reduced expression of pituitary gonadotropins. To address the role of Foxp3 in gonadal function, we examined the gonadal phenotype of these mice. Foxp3 mutant mice have significantly reduced seminal vesicle and testis weights compared with Foxp3(+/Y) littermates. Spermatogenesis in Foxp3 mutant males is arrested prior to spermatid elongation. Activation of luteinizing hormone signaling in Foxp3 mutant mice …

The Creatures We “Assessinate”: Mental Testing As Science Fiction In Chicago Public High Schools In 1909, Clayton Funk

Journal of Social Theory in Art Education

This article tracks the development of what educators and psychologists, in 1909, termed “mental testing” in relation to art education in Chicago Public Schools (CPS). According to CPS Superintendent Edwin G. Cooley (1857-1923) American civilization was in trouble due to the influx of Southern and Eastern European immigrants in Chicago. He and other educators sought to ward off the social collapse they feared with the efficiency of science. As part of what Sol Cohen termed the “medicalization of education,” Chicago’s Department of Child Study tested students for mental capacity and those considered less intelligence were placed in technical classes, while …

Muscle Metaboreflex Control Of Cardiovascular Function In Hypertension, Marty Daniel Spranger

Wayne State University Dissertations

Skeletal muscle ischemia during or immediately following exercise leads to the accumulation of metabolites (e.g., lactate, proton and diprotonated phosphate) which activate chemoreceptive afferents within the muscle leading to a reflex increase in sympathetic outflow generating substantial increases in mean arterial pressure (MAP), cardiac output (CO) and heart rate (HR) - termed the muscle metaboreflex. When the reflex is activated during submaximal dynamic exercise, the pressor response occurs via increased CO with no net peripheral vasoconstriction. When metaboreflex activation is sustained during the recovery from exercise (i.e., post-exercise muscle ischemia - (PEMI)), whereas MAP remains elevated for as long as …

Biofuels Production Via Catalytic Hydrocracking Of Ddgs Corn Oil And Hydrothermal Decarboxylation Of Oleic Acid Over Transition Metal Carbides Supported On Al-Sba-15, Basem A. Al Alwan

Wayne State University Dissertations

The purpose of this research is to minimize the gap between the production of biofuels and the production of petroleum-based fuels by developing catalysts that can utilize renewable non-food based feedstocks (waste vegetable oils, algal oil, brown grease, etc.) and have great performance under low operation conditions. In particular, green diesel has become an attractive biofuel due to its superior properties that are quite similar to petroleum diesel. Therefore, no modifications are required to existing infrastructures. Three distinct experimental phases have been identified in order to achieve the objective of this work as follow:

First, the hydrocracking of distillers dried …

Species - Dependent Cardiac And Motor Responses To Cholinergic Stimulation In Daphnia Pulex And Daphnia Magna, Bryan James Hannan

Wayne State University Theses

The role of acetylcholine (ACh) in regulating the activity of the heart and `feeding current' driven by the beating thoracic appendages of Daphnia pulex and Daphnia magna was evaluated using acetylcholinesterase inhibitors (AChE-I) and muscarinic receptor agonists. Single animals, tethered to a stainless steel pin, were tested in a watertight aquatic chamber that allowed free movement of appendages and swimming antennae. Heart contraction rate and the rate of thoracic appendage beating were quantified optically by measuring fluctuating changes in light-intensity caused by movement. Physostigmine, neostigmine, oxotremorine, pilocarpine as well as nicotine were used to study ACh and AChE. Atropine was …

The Effects Of Phragmites Australis Litter On Seed Emergence In The Erie-Huron Corridor, Michigan, Travis White

Wayne State University Theses

The invasive reed, Phragmites australis, is widespread within the Great Lakes region, and is often blamed for habitat degradation. Once established, it creates dense litter mats that may persist following remediation efforts of living stock removal. We investigated the effects of P. australis and Typha angustifolia, narrow-leaf cattail, litter on seedling emergence from the native seed bank by harvesting soils from five Great Lakes coastal marshes densely populated by either Phragmites or Typha and exposing them to Phramities or Typha litter in treatments of varying litter depths. Seedling emergences were quantified for six weeks. Soils from Phragmites dominated sites had …

What Is In A Percentage?: Calculation As The Poetic Translation Of Human Rights, Andrea Ballestero

Indiana Journal of Global Legal Studies

Increasingly, the efficacy of human rights, international norms, and commercial standards is deposited in numbers as measures of social and financial value. Taking the form of indicators, goals, and targets, these numbers are active participants in the everyday practices through which the law is constituted around the world. This paper examines the normative ability of percentages as numeric devices that transform measures of value across legal domains. The paper draws on two examples: a) the generation of indicators by NGOs promoting the Human Right to Water, and b) the technical work of regulators attempting to regulate water prices to follow …

Regular Soybeans: Translation And Framing In The Ontological Politics Of A Coup, Kregg Hetherington

Indiana Journal of Global Legal Studies

This paper argues for understanding the regulation and standardization of objects as fundamentally about "adding" to those objects rather than reducing or simplifying them. The analysis is based on the ethnographic study of regulatory politics in Paraguayan soybean production over the course of two decades in which the Paraguayan state increased its regulatory capacity immensely. By looking at very different forms of regulatory intervention, it shows that each regulatory moment can best be understood as a "translation" which adds to the complexity of the objects in question by adding new actors and concerns to their circulation. This provides a more …

Competition Law Reform In Turkey: Actors, Networks, Translations, Ziya Umut Turem

Indiana Journal of Global Legal Studies

This article explains the shift from an initially European-oriented and politically motivated competition law, toward a U.S. style and aspiringly apolitical competition regime in Turkey. Translation is used as an analytic to capture the complex processes of such a shift. The article argues that this shift can be explained first by the broad turn toward the U.S. as a source of state expertise and knowledge production in the context of the Cold War. This broad historical dynamic could only be activated, however, by the emergence of a critical mass of policy entrepreneurs and state officials shifting the momentum of policy …
