Measuring Fire Behavior with Photography

Photography is practical for recording and measuring some aspects of forest fire behavior i f the scale and perspective can be determined. This paper describes a photogrammetric method for measuring flame height and rate of spread for fires on flat terrain. The flames are photographed at known times wi th a camera in front of the advancing fire. Scale and perspective of the photographs are dete...

The problem of how to measure habitual food intake in studies of obesity remains an enigma in nutritional research. The existence of obesity-specific underreporting was rather controversial until the advent of the doubly labelled water technique gave credence to previously anecdotal evidence that such a bias does in fact exist. This paper reviews a number of issues relevant to interpreting diet...
