The invention refers to a specific isoform of MnSOD and its uses for protecting and curing subjects exposed to radiations, specifically space radiations. The sensor detects the movement and positioning of a user’s hands within a three-dimensional space. In a liquid crystal display device of an opposing signal line structure, a high-quality image display is achieved by compensating for the non-symmetry of the transmissivity of the liquid crystal with respect to positive and negative drive voltages to prevent flickering and image persistence. The organic layer is disposed on the n-type oxide semiconductor layer. The control circuit selects the switches to actuate according to a cycling of at least three phases of configuration. The active layer includes photoemissive alkali antimonide material that is epitaxially grown on the substrate.
