Facts, Legends and Myths on the Evolution of Resuscitation

This study aimed to overview in chronological order a number of "facts" and "myths" that have been reported in the literature on the history of resuscitation. In particular, this review presents remarkable resuscitation attempts, innovative techniques and landmarked events that enhanced resuscitation in terms of science, history and intervention from ancient times until today. The resuscitation methods were designed for victims needing help in various locations of three-dimensional space, with emphasis on those occurring on, or brought to, land. These methods required single or double rescues to be carried out. Some of them were either empirically or scientifically designed. In some techniques, the stimuli used to revive the victim were rather painful and dangerous or at least disturbing. In some techniques, respiration was attempted with various more or less sophisticated devices. Finally, a small number of cases have been mistakenly reported by previous scholars as resuscitation attempts

Convergence of the stochastic mesh estimator for pricing American options

Broadie and Glasserman proposed a simulation-based method they named {\em stochastic mesh} for pricing high-dimensional American options. Based on simulated states of the assets underlying the option at each exercise opportunity, the method produces an estimator of the option value at each sampled state. Under the mild assumption of the finiteness of certain moments, we derive an asymptotic upper bound on the probability of error of the mesh estimator, where both the error size and the probability bound vanish as the sample size increases. We include the empirical performance for the test problems used by Broadie and Glasserman in a recent unpublished manuscript. We find that the mesh estimator has large bias that decays very slowly with the sample size, suggesting that in applications it will most likely be necessary to employ bias and/or variance reduction techniques

Experiments on The Effect of Ultrasonic Energy on The Absorption of Preservatives By Wood

The effect of ultrasonic energy on the absorption of CCA by spruce, Douglas-fir, and ponderosa pine, as well as the absorption of pentachlorophenol and creosote by the latter species was investigated at atmospheric pressure and 20 C temperature. The results showed an increase in the percentage uptake due to the effect of the ultrasound for all species and preservatives, with the only exception being creosote at immersion times below 30 minutes. The effect of ultrasound was more pronounced in more permeable species

Hollywood Stars’ Involvement in Aquatics and Water Safety

The aim of this educational review article was to identify cases of Hollywood stars who have been involved in aquatics. A literature search was conducted using the terms ‘drowning’, ‘Hollywood’, ‘actor’, rescue’, ‘aquatics’, ‘swimming’ and ‘lifeguard’. It was found that several Hollywood film stars (n = 33; males = 20, females = 13) have worked as lifeguards (n = 12), performed lifeguard rescues (n = 2), or lifesaving rescues (n = 4), were aquatics athletes (n = 6), or suffered drown-related incidents (n = 9). A brief overview of those actors and their involvement in aquatics is presented
