The present invention is directed to a method of sterilizing a surface comprising treating such surface with a vapor comprising peracetic acid at a concentration of at least about 3500 ppm at between about 57\xb0 and about 75\xb0 C. The invention thus relates to the plants, seeds and tissue cultures of the variety CV400845, and to methods for producing a corn plant produced by crossing a corn plant of variety CV400845 with itself or with another corn plant, such as a plant of another variety. At each computing device, the received global center vector table may be filtered to eliminate one or more cluster center entries that are irrelevant to the search queries. A wide variety of radome assemblies of different shapes, styles, and colors can be used in conjunction with a single base assembly. A rock face engaging means is provided adjacent a second end of the shaft to secure the second end of the shaft adjacent the rock face.
