Halsted M. Stone, M.D., oral history interview, December 18, 1992
Dr. Laurie L. Brown, M.D., and Dr. Allen Brown, M.D., conducted this oral history interview at the 145th Annual Meeting of the South Carolina Medical Association (SCMA) at the Omni Hotel in Charleston, South Carolina, on April 23, 1993. In this interview, Dr. Halsted M. Stone, M.D., discusses his family, educational background, career in medicine, and service in organized medicine. Stone also discusses his tenure as a councilor for SCMA and as President for the association from 1980 to 1981. Among the issues facing the association and the field of medicine during his tenure, Dr. Stone notes: healthcare access, rising healthcare costs, high insurance premiums, national health insurance, the establishment of health maintenance organizations for industry professions, and the creation of a committee to help physicians renegotiate salary contracts. Stone also discusses his work in beginning the professional review organization (PSRO) and with South Carolina Governor Richard Riley to place non-physicians on all boards
Rapa Nui (Easter Island)’s Stone Worlds
This article explores the spatial, architectural and conceptual relationships between landscape places, stone quarrying, and stone moving and building during Rapa Nui’s statue-building period. These are central themes of the ‘Rapa Nui Landscapes of Construction Project’ and are discussed using aspects of the findings of our recent fieldwork. The different scales of expression, from the detail of the domestic sphere to the monumental working of quarries, are considered. It is suggested that the impressiveness of Rapa Nui’s stone architecture is its conceptual coherence at the small scale as much as at the large scale. </div

The influence of flow acceleration on stone stability
The stability of a bed of stones subject to a flow is often described in terms of a critical velocity or shear stress generated by the flow. These classical design methods like for example Shields, do not take the influence of flow acceleration into account. In experiments and practice, it appeared that when a flow is accelerated, stones start to move at a point where the so-called critical velocity is not reached yet. The movement of stones must have a second cause beside the velocity of flow. Only a little information is known on the influence of flow acceleration on stone stability of the bed. The objective of this thesis is to obtain more insight into the influence of acceleration of flow on the stability of stones. By carrying out experiments in a flume containing a local contraction, the stone stability in an accelerated flow is investigated. In the contraction the stability of two different stone sizes, subject to different velocity-acceleration combinations, is analysed. If the hypothesis is correct, than for some velocity-acceleration combinations movement occurs while for the same velocity combined with a lower acceleration no movement occurs. The shear stress occurring in the accelerated flow is determined using the shear velocity. According to the classical Shields method the shear velocity is responsible for the movement of the stones. Movement is detected for lower shear velocities then expected. According to the hypothesis this is a result of the extra generated force on the stones due to acceleration. After analysing the data it appeared that combinations of the same velocity and different accelerations showed differences in movement. The amount of movement goes up for an increase in acceleration combined with a constant or slightly decreasing velocity. This proves that there is a relation between the stability of the stones and a combination of the velocity and acceleration generated forces. The Morison equation is used to describe the relation between the forces acting on a stone. It combines the force generated by acceleration and the force generated by the peak velocities due to turbulence, as the sum of both forces. The extra force due to acceleration appeared to be of the same order as the force due to the velocity. Therefore, when looking at the stone stability in an accelerated flow, it is important to take the force generated by the acceleration into account. The resulting Morison force acting on a stone is proved to be responsible for the stability of the stones. Finally, a unique relation, valid for both stone diameters, between the force acting on the stone and the entrainment is found. This power relation consists of a dimensionless Morison-Shields parameter representing the force on a stone and a dimensionless entrainment parameter. The relation does not depend on stone size and is therefore expected to be universal in use.Civil Engineering and Geoscience
