Instructions There are many instructors (and even some studies) which demonstrate the sequence of turbulent diffusion flames leading to a backdraft using small scale models made from cardboard or plywood. Even full-scale models have been used in teaching backdrafts and fire behavior. In each of the training events (or studies), the door or plywood windows are open when the fire is lit. Once the flames become turbulent, then the door or window is closed, unlike on a fire scene. After watching the smoke conditions, the instructor opens the door or window, allowing oxygen-rich air to rush in, creating a backdraft. Some believe this type of training can lead to a false understanding of a backdraft. However, others support this form of training and espouse it is the same as what is seen on the fire ground. Based on what you believe, is it realistic

In financial aspects, a depression is a sustained, long haul downturn in monetary movement in one or more economies. it is a more extreme monetary downturn than a recession, which is a slowdown in financial action through the span of a typical business cycle. a depression is an irregular and extreme type of recession. so depression is always followed by recession but it is not correct to state that a depression always follow a recession.
