A light emitting diode includes a diode structure containing a quantum well, an enhancement layer, and a barrier layer between the enhancement layer and the quantum well. An entrance slit is on the first side of the spectrometer housing and directs light to a cross-disperser grating. A second sensor is mounted on a robot having a wafer-handling arm for checking the position of a wafer that has just been loaded into the boat. Once internalized, the toxin complex dissociates to release the cell toxin, which destroys the target cell. The airborne platform collects solar energy above the clouds and transmits the energy to a receiving station on the ground via a microwave transmission system, avoiding possible attenuating effects of clouds and pollution. The calculation is run on a model of assets, threats, vulnerabilities and countermeasures and enables the production of easy to understand reports and action item lists showing the financial value of threat risks and countermeasures priorities and cost-effectiveness.
