Impact of Mineral Supplementation on Intake Behavior and Blood Flow in Growing Beef Cattle Exposed to Fescue-Derived Alkaloids

Hannah Marie Herzing
Consumption of endophyte-infected tall fescue by cattle has repeatedly been shown to negatively impact dry matter intake (DMI), growth rate, and circulating prolactin concentrations. The objective of the current study was to determine if a mineral supplementation would mitigate the negative effects of fescue-derived alkaloid consumption on feed intake, circulating prolactin, and the vascular system. Twelve Angus crossbred steers were used in a triplicated Latin square design consisting of three 28 d experimental periods. Treatments...

GEOPHYSICAL TECHNIQUES USED FOR THE ANALYSIS AND PREDICTION OF SOIL STRENGTH AND MECHANICAL BEHAVIOR

Matthew A. Hurley
Determining soil properties involves extensive laboratory testing of samples at discrete timing and location. Non-destructive analysis methods, such as electrical and seismic, presents alternatives to means of gathering soil properties accompanied with increased flexibility due to spatial and temporal applications. This research examined the ability of seismic wave data to predict soil behavior such as stress-strain and pore pressures using a modified version of Duncan and Chang (1970). Friction angle predictions were also analyzed using...

Experimental Investigation of Image Distortion in a Mach 6 Hypersonic Flow

Ricky Green
The image distortion that is inherently present when imaging through a flow field at hypersonic speeds was investigated. The original problem involves observation of the outside world from the inside an aircraft moving at hypersonic speeds. For this work, a Mach 6 hypersonic wind tunnel at Wright Patterson Air Force Base (WPAFB) was used and optical patterns were imaged with and without flow field characteristics. Two test campaigns were scheduled to conduct experiments that would...

LANDSLIDE SITE ASSESSMENT AND CHARACTERIZATION USING REMOTE SENSING TECHNIQUES

batmyagmar dashbold
Landslides are common and dangerous natural hazards that occur worldwide, often causing severe direct impacts on human lives, public and private properties. It is imperative to identify the landslide susceptible areas to avoid or mitigate the possible damage. Landslide prediction can be presented in a slope failure in spatial and/ or temporal terms. If it is presented in spatial term, it is considered a landslide susceptibility map (LSM) defined as the probability of spatial occurrence...

MECHANICAL DEVIATIONS AND VERBAL-CUE ALTERED GAIT IN THE FEMOROACETABULAR IMPINGEMENT SYNDROME POPULATION

Walter Menke
Femoroacetabular impingement syndrome (FAIS) is an abnormal physical hip morphology that causes functional changes and pain during gait. Mechanical gait differences in this population require further biomechanical investigation to elucidate characteristics unique to this group. Fixed speed gait trials were performed on force plates and analyzed in addition to isokinetic strength testing to find a multitude of biomechanical variables including joint moment, joint power, joint work, and peak joint angle. This work has discovered evidence...

The Effect of Oil Type, Oil Quality, Vitamin E, and Phytase Supplementation on Broiler Performance, Apparent Nutrient and Energy Utilization, and the Fatty Acid Profile of Fat and Liver in Broiler Chickens

Richard Adefioye
Two experiments were conducted to examine the effects of oil type, oil quality, phytase, and vitamin E (VE) supplementation in broiler chickens. Experiment 1 used 378-day-old male by-product Cobb breeder chicks with 9 treatments, 7 replicates, and 6 birds per replicate, structured as a 2x2x2+1 factorial arrangement of treatments for 14 days. The first 8 treatments were based on a marginally non-phytate phosphorus (NPP) deficient diet (0.31%), while treatment 9 was a positive control (PC)...

The objective of this study is to evaluate nutrition-related lifestyle behaviors and self-perceived nutrition knowledge of university music students before and after a targeted nutrition education session. A baseline Qualtrics survey was administered to undergraduate and graduate music students (18+ years) via the University of Kentucky School...

S. gordonii-PRODUCED HYDROGEN PEROXIDE MODULATES miR-663A AND CCL20 EXPRESSION IN ORAL EPITHELIAL CELLS

Marshall Houston Maynard
The mechanisms through which a persistent recognition of commensal bacteria by oral epithelial cells (OECs) mitigates an uncontrolled inflammatory response of the oral mucosa remain unknown. CCL20 secretion by OECs in response to pathogenic bacteria is regulated by S. gordonii (Sg)-induced miR-663a; nevertheless, the mechanisms involved in these Sg-modulated responses remain to be elucidated. Since Sg is a hydrogen peroxide (H2O2) producer, and H2O2 has been shown to stimulate miRNA expression, we hypothesized that H2O2...

BIRTH MOTHERS’ EXPERIENCES OF SUPPORT BEFORE, DURING, AND AFTER ADOPTIVE PLACEMENT

Ciara Watkins
The current study explores the perceptions and experiences of support in a sample of birth mothers who relinquished parental rights though open or closed private adoption (e.g., religiously, and non-religiously affiliated private adoption agencies, adoption attorneys). Participants (N = 51) were birth mothers who placed a child for adoption at birth or within several months and who relinquished parenting rights 8 months to 50 years ago, with (M = 15.39) years since placement. A thematic...

An Examination of Communication Sequencing in Enacted Support Interactions for People with Major Depressive Disorder

Madison Adams
Social support is integral to helping one manage Major Depressive Disorder [MDD], but enacted social support, or the supportive behavior itself, is not always beneficial. Using a normative theoretical perspective on social support and theory related to sequencing as guiding frameworks, in this thesis I examined common sequential patterns of enacted support between support providers and individuals with MDD. Moreover, I investigated how individuals with MDD evaluated the helpfulness of each of the different sequential...

THE EFFECT OF ENDOPHYTE-INFECTED TALL FESCUE SEED CONSUMPTION ON GUT AND SATIETY HORMONES RELATED TO INTAKE REGULATION IN HOLSTEIN STEERS

Mindy Elizabeth King
Cattle consuming endophyte-infected tall fescue (E+) typically experience a syndrome termed fescue toxicosis which is thought to be caused by ergot alkaloids produced by the endophyte. The most abundant alkaloid, and considered the most likely cause of the syndrome, is ergovaline (ERV). During fescue toxicosis, a decrease in ADG is observed which is likely due to the decrease in DMI commonly observed in animals consuming E+ compared to animals consuming non-endophyte-infected tall fescue (E-). However,...

Sara Schuer
Constant time delay (CTD) is a near-errorless response prompting procedure that involves a presentation of a stimulus, a delay interval, and a controlling prompt. The purpose of this study was to determine the effectiveness of teaching vowel/consonant digraph sounds to children with mild disabilities using constant time delay. A multiple probe (conditions) across behaviors design, replicated with three students, was used. The results indicated that CTD is effective in teaching vowel/consonant digraphs to elementary students...

Hepatitis B virus middle surface antigen loss promotes clinical variant persistence in mouse models

Junyu Lin, Jing Li, Peilin Xie, Yue Han, Demin Yu, Jia Chen & Xinxin Zhang
Hepatitis B virus (HBV) middle surface antigen (MHBs) mutation or deletion occurs in patients with chronic HBV infection. However, the functional role of MHBs in HBV infection is still an enigma. Here, we reported that 7.33% (11/150) isolates of CHB patients had MHBs start codon mutations compared with 0.00% (0/146) in acute hepatitis B (AHB) patients. Interestingly, MHBs loss accounted for 11.88% (126/1061) isolates from NCBI GenBank, compared with 0.09% (1/1061) and 0.00% (0/1061) for...

QUANTIFYING THE SOURCE AND PATHWAY OF DISSOLVED REACTIVE PHOSPHATE IN KARST DRAINAGE OF THE INNER-BLUEGRASS

Cory Radcliff
In the Midwestern U.S. seasonal hypoxia experienced in the Gulf of Mexico and harmful algal blooms in inland freshwater ponds, lakes, and rivers are partly fueled by dissolved orthophosphate loadings from disturbed landscapes. Efforts to reduce dissolved reactive phosphate (DRP) loadings have had varying levels of success and have led to insufficient water quality improvements. Inefficiencies in conservation strategies can stem from poor understanding of phosphate source and flow pathway dynamics. This study focused on...

What's in the Pan

Hannah Leigh Somerville
The fragipan is a common diagnostic soil feature that does not follow a clear development path. Fragipans are found commonly throughout the southeastern US and cover 2.7 million acres in Kentucky alone. However prevalent, there is no currently accepted genesis theory for fragipans. In this study, we sought to better understand the formation of fragic features in Kentucky’s soils by evaluating fragipan characteristics across a sequence of pedons featuring varying degrees of fragipan development. We...

Admittance Modeling for Elastic Thickness Across the Mars Crustal Dichotomy Boundary

Aspen Davis
We use a Bouguer mass-sheet approximation for spectral admittance and correlation modeling to estimate elastic thickness, crustal thickness, crustal density, and load density across the Mars crustal dichotomy boundary near the landing site of NASA’s InSight Lander. We derive and constrain the parameter ranges using RMS misfit between the observed and theoretical admittance and their error bars. Spherical cap windows of 15° (900 km) radius are used to study 15 locations in the Northern Lowlands,...

Accelerometer-Based Vigilance State Classification in Dairy Cows

Evan King
Globally, dairy farming is a $700 billion industry, with more than 9 million dairy cows in the United States alone. Depriving cows of required activities such as sleep has been shown to negatively impact reproductive efficiency, decrease the volume of milk produced, and increase the risk of culling. Overcrowded herds can decrease individual animal health, demanding the need for automatic behavior detection that would provide insight into their state of health. Using electroencephalography (EEG), electrooculography...

Discovery of novel serum metabolic biomarkers in patients with polycystic ovarian syndrome and premature ovarian failure

Jiying Chen, Qinger Zhou, Yonggang Zhang, Wenqing Tan, Hanchao Gao, Liying Zhou, Shuixiu Xiao, Jinhua Gao, Jing Li & Zhiying Zhu
Several widely recognized metabolites play a role in regulating the pathophysiological processes of various disorders. Nonetheless, the lack of effective biomarkers for the early diagnosis of polycystic ovarian syndrome (PCOS) and premature ovarian failure (POF) has led to the discovery of serum-based metabolic biomarkers for these disorders. We aimed to identify various differentially expressed metabolites (DEMs) through serum-based metabolic profiling in patients with PCOS and POF and in healthy individuals by using liquid chromatography–mass spectrometry...

COMPARING BEOPT (EnergyPlus) ENERGY PREDICTIONS TO MEASURED CIRCUIT LEVEL ENERGY CONSUMPTION OF 12 SIMILAR SMALL ENERGY-EFFICIENT SINGLE-FAMILY RESIDENCES

Braydi McPherson-Hathaway
Residential energy usage patterns change as a result of new building codes, renewable technologies, household electronics, and changes in occupancy habits. Building simulations have used end-use energy studies to inform occupancy profiles and overall usage characteristics for the building simulations. Building simulations allow designers, engineers, policymakers, code developers, and building owners to model proposed designs to new and existing buildings, thus it is imperative that the energy profiles used in the models are accurate. In...
