Current Measurements in the York River near the Coleman Bridge
In support of Tidewater Construction Corporation\u27s project to widen the George P. Coleman Bridge, current measurements were conducted in the York River between Gloucester Point and Yorktown, Virginia, along both sides of the bridge. The objective was to sample the currents at approximately 10 feet below the water surface during maximum ebb and flood flow, at enough locations to resolve cross-river variations in the flow field. This objective was well satisfied with multiple surveys conducted during ebb, slack, and flood phases of the tidal flow, each survey providing current data at multiple depths. Significant cross-river variability was documented
A Survey To Determine The Relationship Between The Elderly\u27S And The Family’S Perception Of Aging
The purpose of this study was to determine the relationship between the elderly*s and family\u27s perceptions of aging. The null hypothesis stated that when the elderly\u27s and family\u27s perceptions of aging were compared, as determined by scores on the Perceptions about Aging survey, there would be no significant difference at the .05 level. Data were collected from 60 subjects. Thirty were individuals age 65 and above, and 3 0 were non-elderly family members, one for each participant, who had had contact with the elderly subject at least once a week. All subjects were administered the Perceptions about Aging survey. The scores of the elderly and family member were then compared utilizing the t-test at the .05 level of significance. The results demonstrated a significant difference between the elderly\u27s and family\u27s perceptions of aging, Thus, the researcher rejected the null hypothesis
Field study of currents at Norfolk Naval Shipyard, Portsmouth, Virginia
As a component of an investigation into biofouling problems near the Norfolk Naval Shipyard, a field study of currents was conducted in the Southern Branch of the Elizabeth River in the vicinity of the shipyard\u27s aircraft carrier slips. The objective of this study was to determine the magnitude and direction of currents in an area encompassing the turning basin adjacent to the slips, and the transitional regions to the north and south where the river tapers from a width of approximately 600 m in the turning basin to its more typical width of 150 m. To the north, the transition is gradual; to the south it is abrupt
