The Effect of Competitive Swimming on Oral Health Status
Objectives/Aims: Competitive athletes are often considered to be susceptible to bodily injury. It is now being realized that competitive swimmers are also at risk, specifically in the unsuspected realm of the oral cavity. The purpose of our research is to examine the effect of competitive swimming on an athlete\u27s oral health status.
Methods: Using sources found on Pubmed and Google Scholar, the data used for the correlation of swimming pools and generalized dental trauma are as follows: competitive swimmers and non- competitive swimmers were examined for specific variables such as decayed, missing, or restoratively involved teeth, plaque and gingival index, and the presence of enamel erosion, calculus, and stain. The groups evaluated were divided in terms of activity level involving chlorinated swimming pools.
Results: Three specific oral health effects will be explored throughout our research. The first oral health effect that will be analyzed is the incidence of chlorine induced calculus buildup exhibited in competitive swimmers. Another health effect that will be examined is the process of dental staining that swimmers can experience when in consistent contact with the pool. Lastly, we will explore erosion of enamel that can occur from the lower pH values of pool water. Through various studies, it has been determined that professional swimmers are likely to exhibit a higher prevalence of generalized erosion of dental enamel, generalized dental stain, and chlorine-induced calculus as opposed to individuals who donāt often swim within chlorinated water. This topic is of great importance as the chemical used to disinfect swimming pools causes evident physical and chemical dental trauma in not only professional swimmers, but also individuals who spend more than 6 hours per week in the pool performing vigorous physical exercise.
Conclusion: Oral health in competitive swimmers is a topic that affects many children and adults worldwide, indicating a large prevalence of dental trauma without obvious correlation to the swimming pool despite its significance.https://scholarscompass.vcu.edu/denh_student/1017/thumbnail.jp

Using a Welcome Wagon Approach to Reach Out to Woodland Owners in Appalachian Ohio
A welcome wagon approach was used to provide new forest landowners in southern Ohio with information to help them make informed decisions about the management of their forest resources. New forest landowner information was gathered from county auditor records, and landowners were provided with contact information for agencies and organizations to consult for assistance and an invitation to pick up a woodland owner resource packet containing a wide array of materials and information to help them with the management process

Re-examining the U.K.'s greatest tornado outbreak: forecasting the limited extent of tornadoes along a cold front
On 23 November 1981, a strong cold front swept across the U.K., producing tornadoes from the west to the east coasts. An extensive campaign to collect tornado reports by the Tornado and Storm Research Organisation (TORRO) resulted in 104 reports, the largest U.K. outbreak. The front was simulated with a convection-permitting numerical model down to 200-m horizontal grid spacing to better understand its evolution and meteorological environment. The event was typical of tornadoes in the U.K., with convective available potential energy (CAPE) less than 150 J kg-1, 0-1-km wind shear of 10-20 m s-1, and a narrow cold-frontal rainband forming precipitation cores and gaps. A line of cyclonic absolute vorticity existed along the front, with maxima as large as 0.04 s-1. Some hook-shaped misovortices bore kinematic similarity to supercells. The narrow swath along which the line was tornadic was bounded on the equatorward side by weak vorticity along the line and on the poleward side by zero CAPE, enclosing a region where the environment was otherwise favorable for tornadogenesis. To determine if the 104 tornado reports were plausible, first possible duplicate reports were eliminated, resulting in as few as 58 tornadoes to as many as 90. Second, the number of possible parent misovortices that may have spawned tornadoes is estimated from model output. The number of plausible tornado reports in the 200-m grid-spacing domain was 22 and as many as 44, whereas the model simulation was used to estimate 30 possible parent misovortices within this domain. These results suggest that 90 reports was plausible
Integrated electrical and mechanical modelling of integrated-full-electric-propulsion systems
Integrated Full Electric Propulsion (IFEP) systems are the subject of much interest at present. Current research is focused on analysing and improving aspects of subsystem and system performance. However, there is a great need to look more widely at the `multi-physics' problem of characterising the dynamic interactions between the electrical and mechanical systems. This paper will discuss the changing nature of modelling and simulation to aid research into IFEP systems, outlining the alternative angle taken by the Advanced Marine Electrical Propulsion Systems (AMEPS) project to characterise and investigate electrical-mechanical system interactions. The paper will describe this approach and highlight the unique challenges associated with the problem, discussing the suitable methods that will be adopted to address these challenges. Finally, an overview of the present and future research opportunities facilitated via the AMEPS project will be presented
