Boart Longyear wireline core retrieval system, an innovation that revolutionized the diamond drilling industry by increasing productivity on the worksite and making tripping core from the bottom of the hole safer for the drilling assistant. Later named the Q Wireline System, the new core retrieval method introduced a level of productivity never before seen in the exploration drilling industry. In 1964 Longyear sold 25 percent of its family-owned stock to FACTS, a Luxembourg-based holding company owned jointly by Boart International and Christensen Diamond Products Company. Three years later FACTS exercised its option to purchase another 25 percent of Longyear's family stock. The
Orbital part of inferior frontal gyrus Cytoarchitectonically it is most closely represented by Brodmann area 47 (BA47). However, BA47 and pars orbitalis are not synonymous, as pars orbitalis specifically refers to a grossly visible gyral region and BA47 refers to the cytoarchitectonic features of brain tissue. "In vivo" neuroscience research almost exclusively discusses the gyral region, although the gyral and cytoarchitectonic terms are frequently used synonymously. Orbital part of inferior frontal gyrus The orbital part of inferior frontal gyrus also known as the pars orbitalis is the orbital part of the inferior frontal gyrus. In the human, this region is bordered by the triangular part of
