Train-induced pressure on pedestrians

A simple analytical model for the train-induced flow and its effects on pedestrians is presented in this paper. The expressions developed for the induced air velocity and pressure on the pedestrian surface, as well as their dependence with time, are obtained from unsteady potential theory. The relevant parameters and their effects are analysed, in particular the sensitivity of the pressure coefficient and its rate of change on the train and pedestrian transverse size, the distance to the tracks and the pressure measurement location on the pedestrian surface. In spite of the extreme simplicity of the model and the expressions obtained, good correlation is observed with previously existing experiments. With this work, an absence of published studies concerning analytical approaches to the problem of vehicle-induced pressure on pedestrians is intended to be covered, allowing for simplified testing procedures.

Crossing Blurred Lines: A Training Program to Train Teachers in Appropriate Sexual Boundaries

Boundaries between students and teachers were once clearly defined. Students only interacted with their teachers at school. Currently, however, boundaries are becoming increasingly unclear. As technology advances, students have more venues to interact with their teachers. In addition, teachers are asked to take on more roles in their students' lives. A significant number of teachers and students engage in inappropriate relationships and the possible damage to students is high. Unfortunately, current training programs do not adequately address how teachers can maintain appropriate boundaries with their charges. This paper outlines a proposal for a new training program to fill this gap. This program utilizes training techniques that have been shown to be useful for adult learners as it helps teachers establish and maintain boundaries as well as incorporating elements of effective prevention programs.

Maximal oxygen consumption in national elite triathletes that train in high altitude

Triathlon is considered an endurance sport composed by the individual disciplines of swimming, cycling and running which are generally completed in this sequential order. It has been suggested that triathlon performance can be predicted by maximal oxygen uptake (VO2max). However, it has also been suggested that some variables such age, gender, fitness, training and ventilator muscles may affect VO2max. It is the aim of this research to measure and analyze the VO2max of 6 national elite triathletes and one national juvenile triathlete, with long experience, training in a high altitude city (1650m). We compare VO2max for female and male groups. We found differences at the VO2max values for these groups. Additionally, we also found high values of VO2max for these young elite triathletes despite their relative short age, but long sport age.
