STUDY DESIGN Mail survey of cheerleading-related training and injuries. OBJECTIVE To collect and describe injury frequency, distribution, and associated factors related to the activity of cheerleading. BACKGROUND Estimates indicate that more than 1 million participants are involved in cheerleading at various levels; however, little information exists(More)
Absolute chemiluminescence quantum yields (phi CL) for reactions of bis-(pentachlorophenyl) oxalate (PCPO), hydrogen peroxide (H2O2) and 9:10 diphenyl anthracene (DPA) have been determined. A fully corrected chemiluminescence monitoring spectrometer was calibrated for spectral sensitivity using the chemiluminescence of the bis-(pentachlorophenyl) oxalate(More)
PURPOSE To evaluate the off axis relative biological effectiveness (RBE) for actively scanned proton beams and determine if a constant radial RBE can be assumed. METHODS The PHITS Monte Carlo code paired with a microscopic analytical function was used to determine probability distribution functions of the lineal energy in 0.3µm diameter spheres throughout(More)
PURPOSE To evaluate the dose and biological effectiveness of various ions that could potentially be used for actively scanned particle therapy. METHODS The PHITS Monte Carlo code paired with a microscopic analytical function was used to determine probability distribution functions of the lineal energy in 0.3µm diameter spheres throughout a water phantom.(More)
