Synthesis of tri-aryl ketone amine isomers and their cure with epoxy resins
No full textIsomeric tri-aryl ketone amines, 1,3-bis(3-aminobenzoyl)benzene (133 BABB), 1,3-bis(4-aminobenzoyl)benzene (134 BABB), and 1,4-bis(4-aminobenzoyl)benzene (144 BABB) are synthesized and cured with diglycidyl ether of bisphenol A and diglycidyl ether of bisphenol F in this work. Differential scanning calorimetry and near-infrared spectroscopy reveal higher rate constants and enhanced secondary amine conversion with increasing para substitution attributed to resonance effects and the electron withdrawing nature of the carbonyl linkages. Glass transition temperatures increase from 133 BABB to 134 BABB, but decrease modestly for the 144 BABB hardener. With increasing para substitution, the flexural modulus and strength both decrease while the strain to failure increases but all BABB amines displaying higher mechanical properties than the corresponding 4,4-diaminodiphenyl sulfone (44 DDS) networks. The thermal stability of the BABB networks is found to be modestly lower than 44 DDS, but char yields are significantly higher. Changes in thermal and mechanical properties are described in terms of molecular structure and equilibrium packing density.Novel Aerospace Material
Modification of Cortical Evoked Potential During Induced and Natural Behavioural States in the Hooded Rat
No full textTitle: Modification of Cortical Evoked Potential During Induced and Natural Behavioural States in the Hooded Rat, Author: Thomas L. Babb, Location: ThodeCortical potentials evoked by flashes or clicks were studied in the CER situation and found to increase by over 200% when these evoking stimuli served as conditional stimuli (classical conditioning), when neutral flashes were paired with click CS's (compound conditioning), and when flashes followed painful shock (backward conditioning) which sometimes suppressed bar pressing. Similar increases were evoked in other animals during high voltage slow electroencephalographic sleep or drowsiness. Only cortical components (not afferent activity) of the evoked response were found to increase with these different behavioral conditions, but the changes are not attributed to conditioning per se or dependent on immobility.ThesisMaster of Arts (MA
Reticular Control of Cortical Unit Activity in the Cat
No full textTitle: Reticular Control of Cortical Unit Activity in the Cat, Author: Thomas L. Babb, Location: ThodeExtracellular action potentials were recorded from the suprasylvian gyrus of the cat and compared with slow potentials derived from the overlaying cortical surface in experiments designed to investigate the influences of potine reticular formation on these fast and slow voltage transients. When pontine afferents were blocked by mid-pontine lesion or reversible cooling, the number of recordedable spontaneous and injury discharges was reduced as compared to that recorded from preparations with lower pontine, post-trigeminal, lesions. Bilateral gasserectomies in post-trigeminal preparations did not reduce unit activity. However, the mean and median average firing rates and the patterns of spontaneously-active cells were not demonstrably different fro high and low pontine preparations. Either EEG synchrony or desynchronization was found to co-0exist with either high or low levels of unit activity.ThesisDoctor of Philosophy (PhD

Short-term DTI predictors of cognitive dysfunction in mild traumatic brain injury
No full textPRIMARY OBJECTIVE: To explore whether baseline diffusion tensor imaging (DTI) metrics are predictive of cognitive functioning 6 months post-injury in patients with mild traumatic brain injury (MTBI). RESEARCH DESIGN: Seventeen patients with MTBI and 29 sex- and age-matched healthy controls were studied. METHODS AND PROCEDURES: Participants underwent an MRI protocol including DTI, at an average of 4.0 (range: 1-10) days post-injury. Mean diffusivity (MD) and fractional anisotropy (FA) were measured in the following white matter (WM) regions: centra semiovale, the genu and the splenium of the corpus callosum and the posterior limb of the internal capsule. Participants underwent neuropsychological (NP) testing at baseline and at 6-month follow-up. Least squares regression analysis was used to evaluate the association of MD and FA with each NP test score at baseline and follow-up. MAIN OUTCOMES AND RESULTS: Compared to controls, average MD was significantly higher (p = 0.02) and average FA significantly lower (p = 0.0001) in MTBI patients. At the follow-up, there was a trend toward a significant association between baseline MD and response speed (r = -0.53, p = 0.087) and a positive correlation between baseline FA and Prioritization form B (r = 0.72, p = 0.003). CONCLUSIONS: DTI may provide short-term non-invasive predictive markers of cognitive functioning in patients with MTBI
Increasing Cervical Cancer Screening in a Federally Qualified Health Center
No full textabstract: Routine cervical cancer screening has significantly decreased the mortality rate of cervical cancer. Today, cervical cancer predominantly affects those who are rarely or never screened. Government programs are in place to provide cervical cancer screening at little to no cost, yet screening rates remain suboptimal. This project evaluated an evidence-based intervention to increase cervical cancer screening among underserved women in a federally qualified health center (FQHC). Female patients ages 21 to 65 years without history of hysterectomy (n=1,710) were sent reminders to their phones through the electronic health record (EHR). The message included educational material about the screening process and an announcement regarding government aid for free or reduced cost screening. The number of patients who made an appointment after receiving the message was assessed two months later. In total, 156 responses were collected, and 28 patients made an appointment for screening. The most frequently observed category of Ethnicity was Hispanic/Latina (n = 24, 86%). The most frequently observed category of Insurance was Title X (n = 13, 46%). The observations for Age had an average of 41.04 (SD = 9.93). Using an EHR communication function to send motivational reminders has shown some promise for increasing cervical cancer screening, thereby reducing cervical cancer mortality among the underserved

Summer at Yasnya Polyana: a one act play written and directed for the stage
No full textIn Lev Tolstoy’s 1889 novella The Kreutzer Sonata, a husband murders his wife after believing that she and a famous musician had an affair. A decade later, echoes of this story arise in Tolstoy’s personal life, when his wife Sonya develops a ‘relationship’ with Russian composer Sergei Ivanovich Taneyev. Taneyev stayed on the Tolstoy estate, Yasnaya Polyana, for the summers of 1895 and 1896 and became close with the family until 1897 when tensions between husband and wife drastically escalated. Tolstoy scholars’ opinions in regards to this relationship differ drastically: some blame Sonya’s attachment to Sergei Ivanovich as a contributing factor to the demise of one of the world’s greatest literary geniuses, others attest that Sonya and Sergei Ivanovich’s relationship was nothing more than friendship.
Through writing a one act play, Summer at Yasnaya Polyana, that focused on this highly contested relationship, and then directing it on the main stage of Rooke Theatre with the support and mentorship of the Theatre Arts Department, I was able to work as dramaturge, playwright and director.
The play’s text is drawn almost entirely from primary sources, including the diaries and letters of Sonya and Lev Tolstoy, the memoirs of the Tolstoy children and Sonya’s autobiography, as well as biographies written on the Tolstoys and the Tolstoys’ fictional works, including Lev Tolstoy’s The Kreutzer Sonata and Sonya Tolstoy’s novelistic response Song Without Words, which was only recently published in Russia and is currently being translated into English by Professor Michael Katz at Middlebury College.
The play drifts between primary texts, fictional accounts and imagined events, and explores how these different narratives develop our idea of an individual’s character and psyche.Theatre Art
