Feasibility of a critical experiment utilizing uranium dioxide-beryllium oxide with neutron spectrum shifting capabilities

“The goal of this project is to determine the feasibility of utilizing Annular Core Research Reactor (ACRR) fuel in core design with Sandia Pulse Reactor Facility’s (SPRF) Seven Percent Critical Experiment (7uPCX) fuel rods as driver fuel for a critical experiment facility to support future critical and benchmark experiments for the International Criticality Safety Benchmark Evaluation Project (ICSBEP) handbook. This is part of the Critical Experiment Design (CED) process for future criticality experiments. These criticality experiment designs have the main goal of being performed in the same facility at different neutron energy ranges. To test the feasibility of this experiment facility design, analysis was performed on different configurations of the ACRR fuel with the well-characterized 7uPCX driver fuel. Metrics to determine the most suitable configuration included a critical reactor system with 35%-enriched 235U ACRR fuel, ability to acquire beryllium and beryllium oxide cross section data through the critical experiment, and spectrum shifting beyond regular nuclear physics of criticality. The final results yielded a critical experiment design using fully built ACRR fuel elements with a neutron energy spectrum that is 78.15% thermal, 15.76% intermediate, and 5.73% fast. This final design of a critical experiment facility is for a thermal neutron energy experiment design. Many variations were performed on this thermal design and found to have difficulty shifting the neutron energy spectrum into higher energy ranges. With ongoing work, an intermediate neutron energy experiment design may be created in a way to fit in this facility”--Abstract, page iii

Evolution of Occupational Therapy Practice: Life History of Catherine Bailey, MOT, OTR/L

Purpose: This project gathered information about the history and evolution of OT practice in North Dakota and Wyoming through life histories of individuals who have been influential in developing occupational therapy (OT) in these two states. Catherine Bailey was selected to participate; she has been practicing for approximately 40 years and has influenced OT practice in the state of Wyoming. Method: Data was collected through participant interview. The interview was audio recorded and transcribed. Data was then coded and collapsed into categories with corresponding themes. The researchers utilized the Kawa Model (Turpin and Iwama, 2011) and a timeline provided by Catherine to guide their research. This allowed the researchers to gain a rich understanding of the participant\u27s life. Findings: Catherine feels that OT becomes a lifestyle in which education, life-long learning, and multidisciplinary client-centered practice are keys to success. OT is easily integrated into all aspects of life

Maternal caregivers have confluence of altered cortisol, high reward-driven eating, and worse metabolic health.

Animal models have shown that chronic stress increases cortisol, which contributes to overeating of highly palatable food, increased abdominal fat and lower cortisol reactivity. Few studies in humans have simultaneously examined these trajectories. We examined premenopausal women, either mothers of children with a diagnosis of an autism spectrum disorder (n = 92) or mothers of neurotypical children (n = 91). At baseline and 2-years, we assessed hair cortisol, metabolic health, and reward-based eating. We compared groups cross-sectionally and prospectively, accounting for BMI change. Caregivers, relative to controls, had lower cumulative hair cortisol at each time point, with no decreases over time. Caregivers also had stable levels of poor metabolic functioning and greater reward-based eating across both time points, and evidenced increased abdominal fat prospectively (all ps ≤.05), independent of change in BMI. This pattern of findings suggest that individuals under chronic stress, such as caregivers, would benefit from tailored interventions focusing on better regulation of stress and eating in tandem to prevent early onset of metabolic disease, regardless of weight status

Personal README Files: User Manuals for Library Staff

Presentation given at the Designing for Digital Conference in Austin, Texas, on Monday, March 9, 2020.Teams at three libraries are using personal README files to improve communication. As README files tell you how to use software, personal README files tell you how best to interact with teammates. Presenters will share the hows, whys and benefits of incorporating personal README files into your team's practice.https://deepblue.lib.umich.edu/bitstream/2027.42/154114/1/Personal README Files- User Manuals for Library Staff.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/154114/2/Personal README Files- User Manuals for Library Staff (with speaker notes).pdfDescription of Personal README Files- User Manuals for Library Staff.pdf : Presentation slidesDescription of Personal README Files- User Manuals for Library Staff (with speaker notes).pdf : Presentation slides with speaker note

Jargon-Free Librarianing: Speaking the Language of Our Patrons

Eliminating jargon from our reference interactions, information literacy classes, and online resources is an undertaking that requires cooperation and input from all library departments. Through collaboration with Reference & Research Services and Information Delivery Services, we examined ways our University Libraries currently presents itself both through user experience with our website, during chat and in-person reference interactions, and in information literacy instruction sessions. Our poster will identify core problems jargon-overload present. We will look at how these problems and inconsistencies impact user experience from a Resources Discovery perspective, and provide specific examples from our library. We will provide visuals that show how language is used in library instruction and reference interactions, both in person and virtually. By looking at examples of terminology used in resource discovery, face-to-face instruction and virtual interaction, we can identify areas where natural language can take precedence. Use of consistent natural language in information literacy instruction, reference interactions and resource discovery will provide patrons with the language that they need to develop information-seeking and analyzing skills that will benefit them long after they leave the University. Librarians are notorious for speaking in jargon, often to the detriment of our users. By examining the words we use to communicate with people from both the resource discovery and instruction perspectives, we are seeking ways to break down barriers between ourselves as librarians and our users by providing consistency in both face-to-face communication and virtual interactions with our resource discovery systems
