A new and distinct Sutera plant named \u2018DANGUL16\u2019 particularly characterized by 5-petalled flowers, measuring 2. Artifacts in the cross-sectional images are hereby weakened and pathological structures to be detected are high-lighted. Through the choice of a substrate having a smaller thermal expansion coefficient than the semiconductor material, particularly strong tensile stresses occur in the semiconductor material or the component layer sequence during cooling, which stresses lead to cracking. The step device also includes a plurality of steps movable between collapsed and deployed configurations. Two or more such units are used in an adsorption heat pump.
