Purpose Assessing functional mobility is an important aspect of determining fall risk in the growing population of assisted living. Little is known about the sit-to-walk (STW) transition, especially what characteristics correlate with the duration it takes to perform a STW. Methods In this cross-sectional, exploratory study, 45 assisted living residents were evaluated for baseline measures: history of falls, assistive device (AD), lower-extremity strength, and balance (Tinetti POMA). The residents were then timed performing a STW, and, from these durations, were stratified into fast and slow groups. Statistical analysis was performed to determine relationships between the two duration groups and the baseline measures. Results Participants who had experienced a fall were significantly more likely to use an assistive device (p = 0.001). The use of an AD had a moderate negative correlation with composite strength (r = -0.428, p = 0.003). Duration of STW had a weak negative correlation with composite strength (r = -0.299, p = 0.046) and a moderate correlation with use of AD (r = 0.419, p = 0.004). Those with a faster duration of STW had significantly better balance (p = 0.027). Conclusion These correlations support the need for healthcare professionals to address the use of adaptive equipment and physical training when evaluating functional mobility in assisted living residents. Providing appropriate equipment and improving overall strength in these individuals can help reduce their risk of falls. Individuals in assisted living facilities can be assessed similar to other geriatric populations, with special consideration on functional tasks and measures.

Purpose Balance training and reducing falls have been studied in populations with specific pathologies or using exercise in general. The purpose of this systematic review was to evaluate and summarize the findings of quality randomized control trials using balance training to determine risk and prevalence of falls in communitydwelling older adults. Methods Studies that examined the effects of a balance intervention or balance and exercise intervention on fall risk and/or prevalence in people 65 years or older were included. Relative risk reduction (RRR) ratios were calculated for total number of falls and total number of participants who fell in the included studies. Results Nine randomized clinical trials (n= 4,703) published from 20022019 with Physiotherapy Evidence Database (PEDro) scale scores of ≥4/10 found that balance training programs alone and combined balance and exercise interventions had a significant impact on fall rates with RRR of .30 (.27.33, 95% CI) and fall risk RRR of .42 (.38.46, 95% CI). Conclusion Balance training of various forms can be beneficial in reducing risk and prevalence of falls in independent, communitydwelling older adults.
Novel homogeneous burnable poisons in pressurized water reactor ceramic fuel

Due to excess reactivity, fresh nuclear fuel often contains burnable poisons. This research looks at six different burnable poisons and their impacts on reactivity, material attractiveness, and waste management. An MCNP simulation of a PWR fuel pin was performed with a fuel burnup of 60 GWd/MTHM to determine when each burnable poison fuel type would decrease below a k<sub>∞</sub> of 1. For determining the plutonium material attractiveness in each burnable poison fuel type, the plutonium isotopic content of the used fuel was evaluated using Bathke's Figure of Merit formula. For the waste management analysis, the thermal output of each burnable poison fuel type was determined through ORIGEN decay simulations at 100 and 300 years after being discharged from the core. The performance of all six burnable poisons varied over the three criteria considered and no single burnable poison performed best in all three considerations.
