William Roane Aylett, 1833-1900

This thesis grew out of a paper presented in Dr. Joseph C. Robert\u27s Civil War Seminar in January, 1967. At that time the topic was limited to a study of the subject with only a cursory narrative of his life. The decision to expand this topic into a full biography was based on two factors. First, the need for such a study was pointed out by military historian Theodore Ropp in an article in the South Atlantic Quarterly on the Civil War. The second factor involved the material available for this biographical study. In 1966, a large manuscript collection (approx. 2800) items was presented to the Virginia Historical Society, Richmond, Virginia. This collection, entitled Aylett Family Papers is centered around the correspondence of the subject of this biography, William Roane Aylett (1833-1900). It is hoped that this thesis study will contribute to a better understanding of the Civil War period in Virginia

Project Nautilus Phase 2

The often sky-high cost of ocean research prevents many institutions from performing critical research in the ocean. An ocean-based research vessel can cost anywhere from $40,000 to$80,000 a day to operate and as a result few entities are capable of maintaining them. Project Nautilus seeks to lower these costs by removing the human element from oceanic research. To achieve this goal, Project Nautilus has created a two-part unmanned system. The primary component of this system is the remotely operated vehicle (ROV) that dives underwater to collect various data. This ROV will one day be able to autonomously dock and recharge at a dock on the seafloor. The dock will be connected via tether to the second major component of the system, the unmanned surface vessel (USV). The USV will collect renewable energy from available sources and send them down the tether to the dock for charging purposes. Data collected from the ROV will also be sent up the tether to the HUB for storage and transmission back to land. This design will provide new avenues for smaller research institutions to access the ocean

The association between long-term care setting and potentially preventable hospitalizations among older dual eligibles

OBJECTIVE: To compare the probability of experiencing a potentially preventable hospitalization (PPH) between older dual eligible Medicaid home and community-based service (HCBS) users and nursing home residents. DATA SOURCES: Three years of Medicaid and Medicare claims data (2003-2005) from seven states, linked to area characteristics from the Area Resource File. STUDY DESIGN: A primary diagnosis of an ambulatory care sensitive condition on the inpatient hospital claim was used to identify PPHs. We used inverse probability of treatment weighting to mitigate the potential selection of HCBS versus nursing home use. PRINCIPAL FINDINGS: The most frequent conditions accounting for PPHs were the same among the HCBS users and nursing home residents and included congestive heart failure, pneumonia, chronic obstructive pulmonary disease, urinary tract infection, and dehydration. Compared to nursing home residents, elderly HCBS users had an increased probability of experiencing both a PPH and a non-PPH. CONCLUSIONS: HCBS users' increased probability for potentially and non-PPHs suggests a need for more proactive integration of medical and long-term care.published_or_final_versio

U.S. Strategic Petroleum Reserve Vapor Pressure Committee 2009 annual report.

This report comprises an annual summary of activities under the U.S. Strategic Petroleum Reserve (SPR) Vapor Pressure Committee in FY2009. The committee provides guidance to senior project management on the issues of crude oil vapor pressure monitoring nd mitigation. The principal objectives of the vapor pressure program are, in the event of an SPR drawdown, to minimize the impact on the environment and assure worker safety and public health from crude oil vapor emissions. The annual report reviews key program areas ncluding monitoring program status, mitigation program status, new developments in measurements and modeling, and path forward including specific recommendations on cavern sampling for the next year. The contents of this report were first presented to SPR senior anagement in December 2009, in a deliverable from the vapor pressure committee. The current SAND report is an adaptation for the Sandia technical audience
