Adding Resistances and Capacitances in Introductory Electricity

We propose a unified approach to addition of resistors and capacitors such that the formulae are always simply additive. This approach has the advantage of being consistent with the intuition of the students. To demonstrate our point of view, we re-work some well-known end-of-the-chapter textbook problems and propose some additional new problems.Comment: 13 pages, LaTeX, uses additional packages, 7 eps figures; one comment added after the truncated-cone resisto

Application for the 4W Model of Drowning for Prevention, Rescue and Treatment, Research and Education

Previous research has been published about the 4W model of drowning and its four constituent variables (Avramidis, Butterly & Llewellyn, 2007; 2009a; 2009b; 2009c; 2009d; Avramidis, McKenna, Long, Butterly, & Llewellyn, 2010). We presently summarize and suggest applications of the model for the general public, aquatic safety professionals, injury epidemiologists and policy makers
