The effect of FMB11™ and Avicorr probiotics on Salmonella incidence in commercial tom turkeys

This study examined the effect of probiotic treatment on Salmonella incidence in commercial tom turkeys in grow finish barns. Two probiotics were tested and administered through the drinking water. Both probiotics were started at the recommended production stage and given at their specified doses. Ten barns were tested overall, with five barns on the first probiotic and five barns on the second probiotic. Initial incidence of Salmonella was determined with drag swabs when the turkeys were about 17 weeks of age. Barns were assigned a particular treatment on the basis where five sites were used, each site having two barns, each barn receiving a different probiotic. Initial Salmonella incidence was equal for each probiotic. After the turkeys were treated and marketed, post-market drag swabs were taken with the same procedure as the initial drag swabs. Post-market Salmonella incidence was determined for each probiotic. While there was not a statistically significant difference in Salmonella incidence between each probiotic, there was a statistically significant reduction in Salmonella incidence overall. Results indicated a 30% reduction in Salmonella incidence after treatment with a probiotic. Furthermore, the data comparing each probiotic against each other, while not statistically significant due to low sample size, does seem to favor one probiotic over the other. With additional research, this could potentially become statistically significant. According to the results of this study, overall use of either probiotic does reduce the incidence of Salmonella in commercial market age heavy tom turkeys. However, there were uncontrollable factors that may have had an effect on the results. Weather, humidity, and litter conditions were observably inconsistent during pre-swab and post-swab analysis, which may have affected the survival of Salmonella. Furthermore, due to an infectious disease, several barns required antibiotic treatment during this study; removal of their data was not statistically significant.Undergraduate Research Scholarship - College of AgricultureNo embarg

Visitor At-Destination Search for Travel-Related Services

The phenomenon of at-destination search activity and decision processes utilized by visitors to a location is predominantly an academic unknown. As destinations and organizations increasingly compete for their share of the travel dollar, it is evident that more research need to be done regarding how consumers obtain information once they arrive at a destination. This study examined visitor referral recommendations provided by hotel and non-hotel \u27\u27locals in a moderately-sized community for lodging, food service, and recreational and entertainment venues

Note: Position dependence of time signals picked off a microchannel plate detector

Review of Scientific Instruments, 86(1), 3. doi:10.1063/1.4906327Using an ultrafast laser and a precision mask, we demonstrate that time signals picked off directly from a microchannel plate detector depend on the position of the hit. This causes a time spread of about 280 ps, which can affect the quality of imaging measurements using large detectors. (C) 2015 AIP Publishing LLC

Towards the finite-volume spectrum of the Roper resonance

The finite-volume energy levels corresponding to the Roper resonance based on a two-flavor chiral effective Lagrangian at leading one-loop order are investigated. It is shown that the Roper mass can be extracted from these levels for not too large lattice volumes. Further, to include three-body $N \pi \pi$ dynamics, a non-relativistic effective field theory for the Roper resonance within a covariant particle-dimer picture is introduced. This particle-dimer approach is a suitable framework to investigate three-particle scattering relevant for the Roper channel. The appearing dimer fields are analyzed, the energy levels of the Roper resonance in a finite volume are calculated and compared to the results from the chiral effective Lagrangian.Comment: 11 pages, 5 figures, minor modifications, Proceedings of the 39th International Symposium on Lattice Field Theory, 8th-13th August 2022, Bonn, German

Experiences and Perspectives of High School Football Coaches in Managing Athletic Injuries and Medical Conditions in A Rural Setting

Rural high schools are less likely than urban or suburban high schools to employ an athletic trainer, and this places the responsibility for injury evaluation and management on the coaches. This interpretive case study included interviews and observations of two football coaches from rural Tennessee high schools—one coach who had an athletic trainer and the other who did not have an athletic trainer prior to the fall of 2020. This study aimed to provide an understanding of the coaches’ experiences and perspectives in managing football players’ medical emergencies, acute and chronic injuries, and illnesses. Preliminary study findings will be discussed

Baryon properties from chiral QCD

This thesis contains a collection of studies on the properties of baryons within the context of effective field theory, especially Chiral Perturbation Theory. The thesis focuses primarily on the Roper resonance, an excited state of the nucleon with some interesting and puzzling features. With a pole mass of approximately 1.4 GeV, the Roper mass lies below its quark model prediction. Additionally, the Roper can decay into a nucleon and a pion, as well as into a nucleon and two pions, where both branching ratios are of the same magnitude, causing an almost equal probability of two- and three-particle final states. Investigating the Roper resonance and its properties is key for understanding the excited hadron spectrum of Quantum Chromodynamics. The second part of this thesis studies electric dipole moments (EDMs) of heavy baryons containing a single bottom quark. EDMs are an important observable in precision measurements, since they violate the discrete symmetries time-reversal (T) and parity (P) at the same time. The inclusion of P- and T-violating sources is done within the framework of Standard Model effective field theory (SMEFT). Dimension-six operators from SMEFT are considered and their induced effect on the EDMs of heavy bottom baryons is calculated

Note: Determining the detection efficiency of excited neutral atoms by a microchannel plate detector

Citation: Berry, B., Zohrabi, M., Hayes, D., Ablikim, U., Jochim, B., Severt, T., . . . Ben-Itzhak, I. (2015). Note: Determining the detection efficiency of excited neutral atoms by a microchannel plate detector. Review of Scientific Instruments, 86(4), 3. doi:10.1063/1.4916953We present a method for determining the detection efficiency of neutral atoms relative to keV ions. Excited D* atoms are produced by D-2 fragmentation in a strong laser field. The fragments are detected by a micro-channel plate detector either directly as neutrals or as keV ions following field ionization and acceleration by a static electric field. Moreover, we propose a new mechanism by which neutrals are detected. We show that the ratio of the yield of neutrals and ions can be related to the relative detection efficiency of these species.
