Shrub encroachment has become a problem inmany rangeland systems across the United States due to a reduction in the disturbances, primarily fire, which historically maintained them. The shrub saw palmetto (Serenoa repens) has become abundant in many habitats of the southeastern Coastal Plain, including Florida. When fire regimes are altered or fires are suppressed, this species can proliferate ...

A new liquid sensor probe has been designed by using SH-SAW device. Shear horizontal mode surface acoustic wave (SH-SAW) has a unique characteristic of complete reflection at the free edges of the substrate. The SH-SAWare excited on a 368 YX LiTaO3 and the right angle edge of the substrate has been used to reflect the SAW. Multi-channel reflecting SAW delay lines were constructed on the substra...

We introduce and characterize a new class of polygons that models wood, stone, glass, and ceramic shapes that can be cut with a table saw, lapidary trim saw, or other circular saw. In this model, a circular saw is a line segment (in projection) that can move freely in empty space, but can only cut straight into a portion of material. Once a region of material is separated from the rest, it can ...

In the field of spinal tumors, intralesional tumor cutting is sometimes inevitable. The purpose of this study was to compare the potential for tumor growth after intralesional cutting by T-saw, Gigli saw, and scalpel. Tumors, prepared by the subcutaneous injection of human HT 1080 fibrosarcoma cells in nude mice, were harvested and cut with a T-saw, Gigli saw, or scalpel. A 3-cm wound was creat...
