The Vaikhanasas are mentioned in many Vedic texts, and they maintain a close affiliation with the Taittiriya school of the Krsna Yajur Veda. Yet they are Vaisnavas, monotheistic worshipers of Visnu. Generally, Vaisnavism is held to be a post-Vedic development. Thus, the Vaikhanasas bridge two key ages in the history of South Asian religion. This text contains many quotations from ancient Vedic literature, and probably some other older original material, as well as architectural and iconographical data of the later first millennium CE. The Vaikhanasas remain relevant today. They are the chief priests (arcakas) in more than half of the Visnu temples in the South Indian states of Tamil Nadu, Andhra Pradesh, and Karnataka-including the renowned Hindu pilgrimage center Tirupati in Andhra Pradesh.

A liquid bridge is a volume of liquid held between two or more solid supports. In the case of small disk supports with a sharp edge, the contact line between the bridge and the support disk will be anchored along the edge of the disk. For these cases the solid presents a geometrical singularity and the contact angle is indeterminate within a given range. This dissertation presents research conducted on liquid bridges with anchored contact lines. The three major topics covered are: determining the role of support geometry on static equilibria, liquid bridge dynamical behavior, and forces exerted by a liquid bridge on a support structure. The work was primarily experimental and conducted in a "Plateau tank" that allowed for the simulation of equivalent low-gravity conditions. The main thrust of the experimental work involved the use of a high resolution optical measurement system for imaging the dynamic zone shape, measurement of the static and dynamic contact angles and non-invasive analysis of excited surface modes. The liquid bridge was manipulated by computer controlled linear actuators which allowed precise control over the physical characteristics of the bridge. Experiments have been carried out to locate a bifurcation point along the maximum volume axisymmetric stability margin. Below the critical slenderness the bifurcation from an axisymmetric to a stable nonaxisymmetric configuration is supercritical. However, above this critical slenderness, the bifurcation is subcritical. A series of experiments analyzed the effect on axisymmetric bridge stability by using support disks of different radii, The shape behavior as transition points were approached, as well as the limiting case of a vanishing support radius was investigated. Experiments were performed to determine the resonant frequencies of axisymmetric bridges subject to lateral vibrations. Anomolous results led to a series of experiments to characterize nonlinearities present in the dynamic bridge shape.
