41. The scheme is as follows : One first defines a reference surface structure for which the I-V spectrum is calculated. 42. One explanation of why transfer does not occur often can be explained in terms of surface structure and deep structure. 43. It is apparent that the local symmetry of the surface structure is twofold while the LEED pattern exhibits a fourfold symmetry. 44. Users generally index at least 2 RHEED scans at different azimuth angles for reliable characterization of the crystal s surface structure . 45. Occasionally large cavities collapse and take entire surface structures down with them, as happened with parts of a vineyard in 1942. 46. Catastrophe theory was based on analyses of the topology, or surface structure , of abstract mathematical shapes endowed with " cusps ." 47. A surface structure can be generated that is biologically attachable by surface modification using laser pulses, allowing better joining with bone. 48. The study used a scanning electron microscope to identify and analyze the unique surface structure of llama and suri alpaca fibers. 49. According to Williams ( 1977 ), the Derived VP Rule converts VPs in surface structure into properties written in lambda notation. 50. A small part of Camp Debert was proposed to be used for the complex along with supporting surface structures and personnel housing.
