Evaluating Feline Release Criteria Following Iodine-131 Therapy For Hyperthyroidism, Anthony Davila
Evaluating Feline Release Criteria Following Iodine-131 Therapy For Hyperthyroidism, Anthony Davila
LSU Master's Theses
Hyperthyroidism is a very common endocrine disorder in both humans and cats. Radioactive iodine ablation therapy is considered the gold standard; however, the patient becomes a radiation source and poses a potential radiological risk to others. The regulations governing when the patient can be released differ between human medicine and veterinary medicine. A human patient can receive up to 33 mCi of I-131 and be discharged the same day; yet a feline patient can receive a dose as low as 2 mCi and require multiple days of hospitalization. This discrepancy has not been satisfactorily addressed; and overly restrictive release criteria …
Life Satisfaction And Healthcare Utilization Among Immigrants To The United States, Merritt Christian Rachel Harrelson
Life Satisfaction And Healthcare Utilization Among Immigrants To The United States, Merritt Christian Rachel Harrelson
LSU Master's Theses
Previous research suggests a relationship between life satisfaction and healthcare utilization or HCU (Habibov & Afandi, 2016; Kim, Park, Sun, Smith, & Peterson, 2014). However, no study was found that examined this relationship among elderly American immigrants. The purpose of this study was to determine whether life satisfaction is linked to HCU for this population. The researcher of the current study applied binary logistic regression to data taken from the Health and Retirement Survey to determine whether changes in life satisfaction could be linked to variance in HCU across seven domains, including hospitalization, overnight nursing home stays, doctors visits, dentist …
Infection Potential Of Rickettsia Felis Via Ingestion, Matthew M. Schexnayder
Infection Potential Of Rickettsia Felis Via Ingestion, Matthew M. Schexnayder
LSU Master's Theses
Rickettsia felis is the etiologic agent of flea-borne spotted fever (FBSF) in humans and a poorly described cause of fever in animals. It is transmitted by its primary arthropod vector and reservoir host, the cat flea Ctenocephalides felis. Known routes of Rickettsia felis transmission between Rickettsia felis-infected cat fleas and vertebrate hosts include cutaneous bites and contamination of cutaneous wounds with infective flea feces. The bulk of FBSF infections occur in young children in Africa, though infections of people at all ages all over the world have been confirmed. As mammals and young children frequently come into contact …
Scintillation Event Localization In Novel Hemi-Ellipsoid Detector For Spect, Hanif R. Soysal
Scintillation Event Localization In Novel Hemi-Ellipsoid Detector For Spect, Hanif R. Soysal
LSU Master's Theses
A high sensitivity Cardiac SPECT system using hemi-ellipsoid crystals with pinhole collimation was previously proposed by Dey et al. To investigate detector resolution for this design, the scintillation light spread on a monolithic hemi-ellipsoidal CsI crystal was simulated using Geant4 Monte Carlo. The expected distribution of scintillation light on the outer surface of the crystal from photoelectric absorption events was obtained from the simulations for selected points inside the crystal. Two sets of simulations were performed. For the first set, a look-up table (LUT) of 12 points was created and each point mapped to its expected light distribution—four points at …
Determination Of Scatter Fractions, Albedos, And Tenth Value Layers For Shielding Of Synchrotron Beamline Hutches, Bethany Lynn Broekhoven
Determination Of Scatter Fractions, Albedos, And Tenth Value Layers For Shielding Of Synchrotron Beamline Hutches, Bethany Lynn Broekhoven
LSU Master's Theses
Synchrotron facilities require substantial amounts of shielding to protect facility staff and researchers. To meet mandatory exposure limits, the traditional combination of time, distance, and shielding of the radiation source are utilized. Because of continuous 24-7 operation of most synchrotrons, time is the least useful tool. The experimental stations for synchrotron x-ray beamlines, called hutches, enforce a minimum distance from the source, but shielding provided by hutch walls is still the principal tool for a synchrotron facility. Currently there is no single resource for synchrotron beamline hutch shielding design in the literature; most hutch shielding is designed through either over-simplified …
Picture Cued And Speech Production Cued Approaches For Speech Sound Learning, Michelyve C. Petit
Picture Cued And Speech Production Cued Approaches For Speech Sound Learning, Michelyve C. Petit
LSU Master's Theses
This study examined the use of speech production cued cards, MorphoPhonic faces (MPF), and plain picture (PP) cards when seeking to remediate speech sound errors, specifically sounds / ɹ / and / s / in the word initial position. Fourteen children were provided articulation therapy at their public school using both stimulus types across four weeks. Each week, the total number of correct productions of target phoneme / s / and /ɹ/ were recorded and averaged. These results were used to graphically showcase trends in their performance with both stimulus types. The results demonstrated that MPF cards were advantageous for …
Assessing The Nutritional Value Of Black Soldier Fly Larvae (Hermetia Illucens) Used For Reptile Foods, Kimberly L. Boykin
Assessing The Nutritional Value Of Black Soldier Fly Larvae (Hermetia Illucens) Used For Reptile Foods, Kimberly L. Boykin
LSU Master's Theses
Black soldier fly (BSF) larvae have been studied extensively in animal feed production, but there is limited research for non-production species, such as reptiles, despite their popularity as a calcium-rich feeder insect. The goals of this thesis were to determine the nutritive value of BSF larvae for a lizard species and as an ingredient in a diet formulated for snakes.
BSF larvae are deficient in fat soluble vitamins (A, D, and E). Using vitamin A as a test nutrient, several factors were identified that affect the success and consistency of gut loading. Based on the results, the following gut loading …
Evaluation Of Ventilation Assistance For Improving Respiratory Reproducibility In Radiation Therapy, Cameron J. Sprowls
Evaluation Of Ventilation Assistance For Improving Respiratory Reproducibility In Radiation Therapy, Cameron J. Sprowls
LSU Master's Theses
Background: Respiratory motion affects all tumor sites in the thorax and abdomen. Variations of the respiratory pattern cause variations of the tumor motion which can result in differences between the planned and delivered dose distributions. Previous breathing guidance techniques have been investigated to improve respiratory reproducibility; however, ventilation assistance has not been investigated. We evaluated using bi-level positive airway pressure (BIPAP) ventilation assistance for improving respiratory reproducibility in patients with tumor sites impacted by respiratory motion.
Methods: Written informed consent was obtained for 10 patients currently undergoing radiation therapy treatment. Patients participated in sessions over their course of treatment, which …
Item Comparison Of Two Language Assessments In Children With Autism Spectrum Disorder, Christina M. Hensgens
Item Comparison Of Two Language Assessments In Children With Autism Spectrum Disorder, Christina M. Hensgens
LSU Master's Theses
The language skills of children with ASD vary across the population and prove challenging to assess for many reasons. The current study was designed to compare two language assessments for children with ASD to gain understanding in determining the best method for assessment. The Preschool Language Scale-5 (PLS-5) is a standardized language assessment commonly used in the field of Speech-Language Pathology, while the Verbal Behavioral Milestones Assessment and Placement Program (VB-MAPP) is commonly used in Applied Behavior Analysis. Scores from children with ASD (N=17) on a total of 64 functionally equivalent items from both assessments were analyzed to determine the …
Acoustic Characteristics Of Vowels Produced By Young Children From The New Orleans Area, Rebecca E. Dorsa
Acoustic Characteristics Of Vowels Produced By Young Children From The New Orleans Area, Rebecca E. Dorsa
LSU Master's Theses
Understanding dialects and their effects on speech and language is integral to the field of speech-language pathology, as dialectal differences could potentially be misdiagnosed as speech or language disorders if these factors are not well-considered. The number and organization of the vowel system of one regional dialect of American English differs from those of another regional dialects. Therefore, understanding the effect of dialect on vowel productions in children can aid in the accurate evaluation of children from various dialectal backgrounds. The aims of the proposed study were to 1) determine the age at which young children develop acoustic markers of …
Relationship Between Subject Pronoun And Verb Finite Marking In Aae-Speaking Children, Emily C. Sossaman
Relationship Between Subject Pronoun And Verb Finite Marking In Aae-Speaking Children, Emily C. Sossaman
LSU Master's Theses
Children learning General American English (GAE) show a relationship between their case marking of subject pronouns and their marking of finite verbs, and this relationship has been found for children with specific language impairment (SLI) and typically developing controls (TD). The relationship between children’s case marking of subject pronouns and finite verb marking has not been examined in children who speak dialects of English that differ from GAE. The purpose of the current study was to examine this relationship in children learning African American English (AAE) as this dialect differs from GAE. The data came from an archival dataset of …
