    Monazite ore is composed of several minerals including several rare earth element (REE) and thorium phosphates. Many past research projects have looked at the extraction of REE from monazite ore but have discarded the thorium phosphate compound as waste. Since thorium could be a possible fuel for state-of-the-art future nuclear reactors, this research focuses on a way to recover thorium from the monazite ore. The overall purpose of this research is to develop a conceptual recovery process that recovers thorium dioxide from monazite ore. In some parts of the world where uranium sources are limited; then, thorium could be used as an important nuclear energy source. The thorium content of monazite varies up to 20% with North American monazite ores containing about 5% thorium. The current process is scaled for a 1000 kg/hr flow of North American monazite ore. The process will start by acid leaching the ore with sulfuric acid at extreme temperatures. The products of this step will be cooled, dissolved in water and filtered so that thorium will be separated. After this filtration, the process is divided into an upper and lower process containing rare earth elements or thorium, respectively. Separate product streams of rare earth oxides and thorium oxide will be achieved as byproducts and products, respectively. The process economics of capital cost and annual operating cost will be evaluated to determine economic feasible of the process

    Local Culture and Community Through a Digital Lens: Viewpoint on Designing and Implementing a Virtual Second Look Event for Residency Applicants

    BackgroundThe COVID-19 pandemic altered how residency interviews occur. Despite 2 years of web-based interviews, these are still perceived as inferior to in-person experiences. Showcasing a program and location is critical for recruitment; however, it is difficult to highlight the program’s location and community digitally. This article presents the authors’ viewpoints on designing and implementing a virtual second look for residency applicants. ObjectiveOur objective was to host a web-based event to feature the benefits of living in Winston-Salem, North Carolina, for residency applicants, enhance recruitment efforts, and ensure a successful residency match. The goal was to cover topics that interested all applicants, highlight how Winston-Salem is a special place to live, involve current residents, and engage community members. MethodsThree programs–child neurology, neurology, and family medicine were chosen for a pilot virtual second look. All residency program directors’ were asked to recommend community contacts and help identify residents and faculty who may serve as content experts on one of the topics in the panel discussions. A total of 24 community leaders from restaurants, venues, schools, and businesses were contacted, and 18 agreed to participate. The panel discussions included living in and raising a family in Winston-Salem, experiencing Winston-Salem arts and music, where to eat and drink like a local, and enjoying sports and outdoors in the area. The 2-hour event was hosted on Zoom. Postevent feedback assessments were automatically sent to each registrant through Research Electronic Data Capture (REDCap). This study was deemed exempt from Wake Forest University Health Sciences institutional review board review (IRB00088703). ResultsThere were 51 registrants for the event, and 28 of 48 registrants provided postevent feedback, which was positive. The authors found in the MATCH residency results that 2 of 2 child neurology positions, 4 of 6 adult neurology positions, and 1 of 10 family medicine positions attended our second look event. One adult neurology resident who did not participate was an internal candidate. All respondents agreed or strongly agreed that the session was valuable, well organized, and met their expectations or goals. Furthermore, all respondents gained new information during this web-based event not obtained during their interview day. ConclusionsThe virtual second look event for residency attendees featured the benefits of living in Winston-Salem, and the perspectives of current residents. Feedback from the session was overall positive; however, a top desire would be devoting more time for the applicants to ask questions directly to the community leaders and our resident trainees. This program could be reproducible by other institutions. It could be broadened to a graduate medical education–wide virtual second look event where all medical and surgical programs could opt to participate, facilitating an equitable opportunity for prospective applicants
