A physically robust light emitting diode is disclosed that offers high-reliability in standard packaging and that will withstand high temperature and high humidity condition. In one embodiment, the present invention provides a device for measuring a body-tissue water content metric as a fraction of the fat-free tissue content of a patient using optical spectrophotometry. Each hermetic joint portion has a nearly R-shaped section. This invention also relates to soybean cultivars, or breeding cultivars, and plant parts derived from soybean variety 96292716, to methods for producing other soybean cultivars, lines or plant parts derived from soybean cultivar 96292716, and to the soybean plants, varieties, and their parts derived from use of those methods. The ingredient is effective for making a food product having a structure and height substantially the same as a corresponding soy-free product made with wheat flour. The heat element is a silicon semiconductor thin film impurity-doped at high concentration.
