Mount Tabor

Yahweh subsumed or incorporated in himself the other gods that he defeated, and went on to embody the totality of Israelite history in his name. He became the terebinth-god or oak-god Bel, Cronos the barley-god, Tammuz the harvest-god, Jupiter and Marduk In Jemsalem, Yahweh was the scarlet oak-god El. At Mount Tabor, he became Dionysus, the Daanan white-bull god. He was Baal-Zephon, Baal-Zubul, Lord of the North or Lord of the Mansions, and Atabyrius As... [Pg.113]

The SFA, originally developed by Tabor and Winterton [56], and later modified by Israelachvili and coworkers [57,58], is ideally suited for measuring molecular level adhesion and deformations. The SFA, shown schematically in Fig. 8i,ii, has been used extensively to measure forces between a variety of surfaces. The SFA combines a Hookian mechanism for measuring force with an interferometer to measure the distance between surfaces. The experimental surfaces are in the form of thin transparent films, and are mounted on cylindrical glass lenses in the SFA using an appropriate adhesive. SFA has been traditionally employed to measure forces between modified mica surfaces. (For a summary of these measurements, see refs. [59,60].) In recent years, several researchers have developed techniques to measure forces between glassy and semicrystalline polymer films, [61-63] silica [64], and silver surfaees [65,66]. The details on the SFA experimental procedure, and the summary of the SFA measurements may be obtained elsewhere (see refs. [57,58], for example.). [Pg.95]

Later, in 1973, Tabor and Israelachvili developed a surface force apparatus, SFA, to measure the interaction force in a vacuum at the 1.5 nm level for the first time. In this equipment, the interaction forces between two crossed cylinders coated with freshly cleaved mica sheets having atomically smooth surfaces were measured. One of the cylinders is mounted on a piezoelectric transducer, and the other cylinder is mounted on a spring of known and adjustable spring constant with a force resolution down to 1CT8N. SFA has been further developed for performing measurements in liquids and vapors. In these developed SFA versions, the separation distance between the cylinders can be measured interfero-... [Pg.268]

The surface forces apparatus (SFA) developed by Tabor, Winterton [30], and Israe-lachvili [56] contains two crossed silica cylinders with a radius of curvature of roughly 1-2 an to which thin sheets of mica are glued to obtain atomically flat surfaces (inset of Figure 3.1). One mica-coated cylinder is mounted to a piezoartuator, which is used to change the distance between the two cylinders when recording force versus distance curves. [Pg.56]
