Abstract: A concrete basement stairway is created, by positioning a stairway form 1 between a first pair of concrete receiving foundation channels 9 and a second pair of concrete receiving foundation channels 9a of any size foundation, the stairway form including a single piece stairstep panel 2, coupled by pivotable latching members, between a pair of parallel inner stairway side panels 6 and 6a, the inner stairway side panels configured to permit concrete to flow between the two pairs of concrete receiving foundation channels and spaces beneath the stairstep panel, in a manner forming a series of solidified concrete steps unified, and thus leak proof, with concrete solidified within the concrete receiving foundation channels. The stairway is formed simultaneously with the foundation so that a builder can complete the job without awaiting shipment of a pre-cast stairway requiring returning to the site. Reusable lightweight aluminum forms are employed for easy handling.

Abstract: The present invention provides novel nucleic acid and protein sequences for an estrogen-regulated GTP-binding protein gamma-12 subunit protein, as well as methods for using the sequences for modulating the effects of estrogen in mammalian cells, methods of detecting estrogen signaling in cells, and methods of identifying compounds capable of acting as an estrogen receptor agonist or antagonist.

Abstract: The present invention provides nucleic acid and protein sequences for a novel estrogen-regulated unconventional myosin protein, as well as methods for using the sequences for modulating the effects of estrogen in mammalian cells, methods of detecting estrogen signaling in cells, and methods of identifying compounds capable of acting as an estrogen receptor agonist or antagonist.

Abstract: A tree guard mat is made from flexible fiber ropes or fibrous strips arranged in concentric rings to form a mat. For installation around a tree, a selected number of inner rings may be removed until a central hole is equal in diameter to the diameter of the tree. In one embodiment, the ends of the concentric rings are joined along a separation radius so that a gap may be created through which the mat can be installed around a tree trunk. The mat is water and gas permeable, and will suppress plant growth around the base of the tree so that trimming is unnecessary.
