Feeding The Future Meat Doesn’T Come Cheap, Lukas C. Southard

Capstones

Cultured – or as it is referred to by companies innovating the technology clean – meat is expected to be the next innovation to change the way the world gets its animal protein. Meat from animal cells grown in a lab seems like science fiction but it is around the corner from hitting your supermarket shelves. The technology has been developed but how these companies intend on scaling up their production to meet retail demands remains a mystery. So far companies have relied on seed and early stage investment from venture capital companies and private sources to fund research. Predictions …

Screening The Cultivable Cave Microbial Mats For The Production Of Antimicrobial Compounds And Antibiotic Resistance, Jerneja Ambrožič Avguštin, Patricia Petrič, Lejla Pašić

International Journal of Speleology

The current work extends the phenotypic characterization of a bacterial culture collection obtained from white, yellow, grey or pink microbial cave wall colonies that are common in the caves of Slovenian Karst. We have determined antibiotic resistance to 22 natural and synthetic antibiotics in 69 isolates from the microbial mats. Thirty-eight isolates (52%) were resistant to 1-5 antibiotics; another 27 isolates (37%) were resistant to 6-10 antibiotics; and 7 isolates (0.1%) were resistant to 11-17 antibiotics. We screened for production of antimicrobial compounds by growing cave isolates on five different media and overlaying individual cultures with ten Gram-positive and Gram …

Food Preferences Among Children At Arcadia Elementary School, Laurel Lee

Community Based Research

My research, conducted from September through November of 2017, showed that the children preferred more processed foods and starches instead of healthier options such as fruits and vegetables, even when healthy options were available. According to the parents/caregivers surveyed, their children prefer to eat processed American meals. Parents/caregivers desired for their children to eat a variety of different foods including fruit, vegetables, proteins, and traditional Hispanic food. This study acknowledges that healthy meal options are available at schools, but there needs to be more research on how to best encourage students to take advantage of these nutritious choices in order …

College-aged female students (N = 112) were recruited from the universities in Seoul and Gyeonggi province, South Korea. The aBMD of the lumbar spine and non-dominant side of the proximal femur (total hip, TH; femoral neck, FN; femoral trochanter, FT) were measured using dual energy X-ray absorptiometry (DXA). Alcohol consumption was determined by the frequency and amount of alcohol intake during …

Bridging The Gaps In Elementary Life Science Lessons, Kaitlin Cook

Honors Program Theses and Projects

The United States is experiencing a rise in science, technology, engineering and mathematics (STEM) careers while facing a shortage of STEM workers. This could partly be due to a decline in the amount of time allowed for science in elementary schools or possibly because many life science lessons in elementary school lack originality and may not stimulate an interest in science. Lack of captivating STEM education prior to college may be contributing to the decline of students graduating with STEM based degrees. My thesis focuses on getting out of the routine of using monotonous life science lesson plans. I identify …

BNW was conceived as an auxiliary component of a parent recruitment program called Bridge to the PhD in Neuroscience Program (BPNP). The objectives of BNW are to identify promising students for BPNP, and to increase awareness of neuroscience as a discipline and a career option. BNW introduces basic concepts in neuroscience using a variety of educational techniques, including mini-lectures, interactive discussions, case studies, experimentation, and …

From Field To Film: Mosquito Surveillance And Survey Of Us Adults' Knowledge And Attitudes Towards Arthropod-Borne Disease Vectors, Justine Laviolette

Department of Entomology: Dissertations, Theses, and Student Research

Mosquito-borne disease is a public health challenge that warrants an active surveillance program for the identification of mosquito populations and the education of the public for prevention and protection against disease-transmitting arthropods. The communication of science to the public is necessary to prevent disease, change behavior, and promote a dialog between scientists and the public.

People are accustomed to high quality entertainment, which begs the question, “If we made science more entertaining, would the public be more interested?”

To address these issues, the objectives of this study are: 1) identify mosquito species and abundance at the US Meat Animal Research …

The Mechanical Development For An Autonomous Forest Service Robot, James P. Walker

Honors College Theses

Georgia’s forests are under threat from numerous invasive species of plant, both herbaceous and woody. A primary factor in the invasive potential of any given non-native plant is the lack of natural predators and rapid reseed and regrowth cycles. To combat invasive plants, this thesis proposes an artificial, robotic predator to provide a means of controlling invasive species. Although autonomous robots are currently being developed for similar agricultural purposes, none have emerged for forestry related tasks, such as proposed in this work. The chassis, inspired by rocker bogie and similar suspension systems, has been redesigned to have eight wheels, to …

Fish Assemblages Of The Withlacoochee River Basin In South Georgia, Usa, Matthew J. Cannister, David L. Bechler

Georgia Journal of Science

An ichthyofauna review of literature prior to 2008 on the Withlacoochee River basin in south-central Georgia, USA, indicated that the fish fauna was underrepresented compared to other rivers, such as the Suwannee River basin in Florida of which the Withlacoochee River is a tributary. A survey would provide the state of Georgia potentially valuable additional information on the fish fauna within the basin. A 45-site survey within the eastern portion of the Withlacoochee River basin was conducted from 2008 to 2010 employing seines, gill nets, fish traps, trotlines, and creel surveys. Surveys yielded 51 fish species of which three, the …

Expression Of Lysine-Mediated Neuropeptide Hormones Controlling Satiety And Appetite In Broiler Chickens, Collins N. Khwatenge, Boniface M. Kimathi, Thyneice Taylor-Bowden, Samuel N. Nahashon

Agricultural and Environmental Sciences Faculty Research

Lysine is the second most limiting amino acid after methionine and is considered the most limiting amino acid for growth in poultry. Lysine requirement for broiler chickens has changed over the years. Leptin and adiponectin represent 2 adipokines that mediate metabolism by eliciting satiety effects whereas ghrelin peptide hormone influences appetite. We hypothesize that this affects growth performance of chicks. This study evaluates the effect of varying dietary lysine homeostasis on performance of broiler chickens through satiety- and appetite-mediating hormones. In 3 replications, 270 one-day-old chicks were reared for 8 wk feeding on diets comprising 0.85, 1.14, and 1.42% lysine …

Agricultural and Environmental Sciences Faculty Research

The caging density required for optimal egg production by various avian species and varieties is highly variable. Even so, little is known of the required cage density for optimum performance of the laying guinea fowl (Numida meleagris). The objective of this study was to assess the effect of varying cage densities on production performance of pearl gray guinea fowl laying hens. In 3 replicates, 270 pearl gray guinea hens [28 wk of age (WOA)] were weighed individually and randomly assigned to laying cages at densities of 1, 2, and 3 birds/cage, equivalent to 1,394, 697, and 465 cm2/bird, respectively.

Effect Of Varying Dietary Concentrations Of Lysine On Growth Performance Of The Pearl Grey Guinea Fowl, Sarayu Bhogoju, Samuel N. Nahashon, Joseph Donkor, Boniface M. Kimathi, Dekarra Johnson, Collins N. Khwatenge, Thyneice Taylor-Bowden

Agricultural and Environmental Sciences Faculty Research

Lysine is the second limiting essential amino acid in poultry nutrition after methionine. Understanding the lysine requirement of poultry is necessary in guiding formulation of least cost diets that effectively meet the nutritional needs of individual birds. The lysine requirement of the Pearl Grey guinea fowl (PGGF) is not known. Therefore, the objective of this study was to assess the appropriate lysine levels required for optimal growth attributes of the PGGF. In a 12-week study, 512 one-day-old Pearl Grey guinea keets were weighed individually and randomly assigned to electrically heated battery brooders. Each battery contained 12 compartments housing 15 birds …

Agricultural and Environmental Sciences Faculty Research

This study was undertaken to assess dietary CP and ME concentrations for optimum growth performance and carcass characteristics of French guinea broilers. In a 3 x 3 factorial arrangement, 396 1-d-old French guinea keets were randomly assigned to experimental diets with 3,050, 3,100, and 3,150 kcal of ME/kg of diet; each contained 21, 23, and 25% CP, respectively, from 0 to 4 wk of age (WOA). From 5 to 8 WOA, experimental diets had 3,100, 3,150, and 3,200 kcal of ME/kg of diet, and each contained 19, 21, and 23% CP, respectively. Each dietary treatment was replicated 3 times, and …

Growth Characteristics Of Pearl Gray Guinea Fowl As Predicted By The Richards, Gompertz, And Logistic Models, Samuel N. Nahashon, Sammy E. Aggrey, Nathaniel Adefope, Abravi Amenyenu, D. Wright

Agricultural and Environmental Sciences Faculty Research

This study was undertaken to describe the growth pattern of the pearl gray Guinea fowl. Using BW data from hatch to 22 wk, 3 nonlinear mathematical functions (Richards, Gompertz, and logistic) were used to estimate growth patterns of the pearl gray guinea fowl. The logistic and Gompertz models are a special case of the Richards model, which has a variable point of inflection defined by the shape or growth trajectory parameter, m. The shape parameter m was 1.08 and 0.98 in males and females, respectively, suggesting that the growth pattern of the pearl gray female guinea fowl is Gompertz. The …

Lysine Mediation Of Neuroendocrine Food Regulation In Guinea Fowl, Ashley C. Payne, Xiaofei Wang, Michael T. Ivy, A. Stewart, Kiimya Nelson, Carl E. Darris, Samuel N. Nahashon

Biology Faculty Research

In poultry, obesity is partly influenced by food intake, and is increasingly becoming a nationwide problem. Hypothalamic food intake mechanisms are involved metabolically and neurologically via two peptide hormones, leptin and ghrelin, and the amino acid glutamate, which is enzymatically derived from lysine metabolism. We hypothesize that lysine homeostasis mediates regulation of feed intake and performance characteristics via the brain–liver axis through glutamate sensing. The objective was to examine the effects of lysine homeostasis in avian food regulation and performance through neuroendocrine signaling. One-day-old male French Guinea fowl (GF) keets (n = 270) were weighed and randomly assigned to 5 …

Accrual Accounting And The Farm Business, Part Ii, Timothy Meyer

Cornhusker Economics

My last Cornhusker Economics article, Accounting Assumptions and the Farm Business (October 16, 2019) set the foundation for a specific evaluation of the conceptual framework accrual accounting offers the farm or ranch manager. The article addressed cash accounting and hinted at its shortfalls which were rectified by accrual accounting. This article will explain conceptual frameworks, and two accrual accounting principles; namely the revenue recognition principle and the matching principle.

During one of my graduate school experiences, I encountered a professor who seemed to be in love with conceptual frameworks. I chose a framework and tried to use it as instructed, …

Potential Health Risks Linked To Emerging Contaminants In Major Rivers And Treated Waters, James Kessler, Diane Dawley, Daniel Crow, Ramin Garmany, Philippe T. Georgel

Biological Sciences Faculty Research

The presence of endocrine-disrupting chemicals (EDCs) in our local waterways is becoming an increasing threat to the surrounding population. These compounds and their degradation products (found in pesticides, herbicides, and plastic waste) are known to interfere with a range of biological functions from reproduction to differentiation. To better understand these effects, we used an in silico ontological pathway analysis to identify the genes affected by the most commonly detected EDCs in large river water supplies, which we grouped together based on four common functions: Organismal injuries, cell death, cancer, and behavior. In addition to EDCs, we included the opioid buprenorphine …

Identification Of Visual Attentional Regions Of The Temporoparietal Junction In Individual Subjects Using A Vivid, Novel Oddball Paradigm, Kathryn J. Devaney, Maya L. Rosen, Emily J. Levin, David C. Somers

Neuroscience: Faculty Publications

The Temporoparietal Junction (TPJ) of the cerebral cortex is a functionally heterogeneous region that also exhibits substantial anatomical variability across individuals. As a result, the precise functional organization of TPJ remains controversial. One or more regions within TPJ support visual attention processes, but the “attention TPJ” is difficult to functionally observe in individual subjects, and thus is typically identified by averaging across a large group of subjects. However, group-averaging also blurs localization and can obscure functional organization. Here, we develop and test an individual-subject approach to identifying attentional TPJ. This paradigm employs novel oddball images with a strong visual drive …
