A system and method for reflowing solder to interconnect a plurality of electronic components to a substrate is disclosed. The front and rear panels define an upwardly opening cavity therebetween for accepting filler material, such as concrete therein. Ineffective solar energy components are described as those exhibiting wavelengths outside the bandgap energy defined wavelength and an associated wavelength defined band of useful photon energy. The combination of the MnOx oxidation catalyst, NOx storage material, and NOx reduction catalyst material serves to complete the oxidation of unburned hydrocarbons and carbon monoxide, and to convert NOx to nitrogen. A filler comprising a hydrogel or a structural protein can be located within the pores. Thus, the route can be switched at the time of route trouble and under particular conditions without arrangement of particular routers by monitoring a state of a network system or a computer previously decided as the monitored object.
