Isolation andCharacterization ofNew Facultatively Alkalophilic Strains ofBacillus Species

The erectable shelter includes a truss framework that provides an elevated, raised canopy that can have a high peak in a raised, extended configuration. The shelter includes a canopy, a leg assembly, and a perimeter truss linkage assembly having a plurality of perimeter truss pairs of link members connected to the leg assembly. The legs preferably have telescoping upper and lower sections with lower section for engagement with ground, and a slider member slidably mounted to the upper section of each of the legs. A canopy peak support assembly is provided that is movable between a raised position and a lowered position, with the canopy peak support assembly supporting the canopy above the top of the leg assembly in the raised position. The canopy peak support assembly includes a flexible center support member such as a rubber tube or spring coil that can bend in response to the force of strong winds.
