An apparatus that includes a suitcase and integrated support arrangements that are transformable from an extended state to provide support for a person to lie down and a stored state for ease of transport. A lower concrete layer is formed by placing concrete in a space defined between the upper and lower flanges and between adjacent web plates through a concrete inlet port formed between the adjacent upper flange, and an upper concrete layer is formed by placing concrete on the upper flange. While new signal lights are being added, the optical power of whole ASE dummy lights or the optical power of the ASE dummy lights in sub-bands adjacent to the sub-band in which the new signal lights are to be added is controlled while increasing the optical power of the new signal lights so that the transmission characteristics of the existing signal lights are not affected by the signal addition. The at least two locations on the container sidewall preferably are nominally aligned with each other in a direction parallel to the container axis. Also provided are methods for using such compositions in the diagnosis or treatment of CNS disorders such as Alzheimer’s disease.
