Capsules containing NaCl-MgCl2 salt with 316L stainless steel or alloy N samples were irradiated in the Ohio State University Research Reactor for 21 non-consecutive hours. A custom irradiation vessel was designed for this purpose, and details on its design and construction are given. Stainless steel samples that were irradiated during exposure had less corrosive attack than samples exposed to the same conditions without irradiation. Alloy N samples showed no significant effect of irradiation. This work shows a method for conducting in-reactor irradiation-corrosion experiments in static molten salts, and presents preliminary data showing that neutron irradiation may decelerate corrosion of alloys in molten chloride salts.

This report highlights some of the major developments in the area of speech anatomy and physiology drawing from the author's own research experience during his years at the University of Iowa and the University of Illinois. He has benefited greatly from mentors including Professors James Curtis, Kenneth Moll, and Hughlett Morris at the University of Iowa and Professor Paul Lauterbur at the University of Illinois. Many colleagues have contributed to the author's work, especially Professors Jerald Moon at the University of Iowa, Bradley Sutton at the University of Illinois, Jamie Perry at East Carolina University, and Youkyung Bae at the Ohio State University. The strength of these researchers and their students bodes well for future advances in knowledge in this important area of speech science.

Background:Educating trainees during cardiology fellowship is a process in constant evolution, with program directors regularly adapting to increasing demands and regulations as they strive to prepare graduates for practice in today’s healthcare environment.Methods and Results:In a 10-year follow-up to a previous manuscript regarding fellowship education, we reviewed the literature regarding the most topical issues facing training programs in 2010, describing our approach at The Ohio State University.Conclusion:In the midst of challenges posed by the increasing complexity of training requirements and documentation, work hour restrictions, and the new definitions of quality and safety, we propose methods of curricula revision and collaboration that may serve as an example to other medical centers.

Background Suppression is associated with binocular vision conditions such as amblyopia and strabismus. Commercial methods of testing fusion often only measure central fusion or suppression at near. The purpose of this pilot study was to assess a new iPad picture fusion test that assesses foveal and central fusion at near. Methods Participants aged 5 years and older presenting for eye examination at The Ohio State University College of Optometry were enrolled. Results from visual acuity, dry and wet refraction/retinoscopy, stereopsis and cover testing were recorded from the patient chart. The iPad picture fusion test, Worth four-dot, Worth type test with foveal letter targets, and Polarized four-dot were performed by one examiner in a randomized order at 40 cm. Testing was repeated with the anaglyphic filters reversed. Crosstabulation and McNemar chi-square analysis were used to compare the results between fusion testing devices. Results Of the fifty participants (mean age = 17.5), twelve reported suppression and one reported diplopia. Testability was excellent for all tests (98% to 100%). There were no significant differences between tests in reported results (P ≥ 0.22 for all comparisons). No difference in reported fusion or suppression status was observed with change in orientation of the anaglyphic filters. Six participants reported foveal suppression alone at near which was not identified with Worth four-dot at near. Conclusion The iPad picture fusion test provided excellent testability and agreement with commonly used tests of fusion and allowed testing of both central and foveal fusion at near. Nearly half (46%) of participants with suppression reported foveal suppression, supporting the importance of testing for foveal suppression.
