    High efficiency thermal to electric energy conversion using selective emitters and spectrally tuned solar cells

    Thermophotovoltaic (TPV) systems are attractive possibilities for direct thermal-to-electric energy conversion, but have typically required the use of black body radiators operating at high temperatures. Recent advances in both the understanding and performance of solid rare-earth oxide selective emitters make possible the use of TPV at temperatures as low as 1500 K. Depending on the nature of parasitic losses, overall thermal-to-electric conversion efficiencies greater than 20 percent are feasible

    A Phase I Cultural Resource Survey of additional acreage for the Raleigh House parcel at Virginia Institute of Marine Science (VIMS) in Gloucester County, Virginia was undertaken by staff of the William and Mary Center for Archaeological Research (WMCAR) on February 8, 1993. This investigation was intended to provide specific information concerning the nature and distribution of potential archaeological and architectural resources within the project area

    A cultural resource overview and preservation plan for the Timberneck Farm property and Catlett Islands, Gloucester County, Virginia

    In January and February, 1992, the William and Mary Center for Archaeological Research (WMCAR) conducted an archaeological overview study of the Timberneck Farm and Catlett Islands in Gloucester County, Virginia under an agreement with the Chesapeake Bay National Estuarine Research Reserve in Virginia (CBNERRVA), Virginia Institute of Marine Science (VIMS). The purpose of the investigation was to assess the archaeological potential of the area and to formulate a framework for management of those cultural resources present

    © JOURNAL OF CONSUMER RESEARCHVariables determining the role of husband and wife in family financial management are explored based on in-home, personal interviews. Financial tasks reflecting implementation activities and two groupings of decision activities were related to component-score variables through discriminant function analysis. Sex-role attitude and educational level were most important in determining the role structure of implementation tasks. Locus of control, wife's working status and reasons for work, and a measure of family life cycle were each significant in determining role structure for a grouping of decision tasks

    A phase I archaeological survey of a new site for the Environmental Toxicology and Pathology Research Center at Virginia Institute of Marine Science, Gloucester County, Virginia

    A Phase I archaeological survey of a new site for the proposed Virginia Institute of Marine Science (VIMS) Environmental Toxicology and Pathology Research Center in Gloucester County, Virginia, was undertaken by staff of the William and Mary Center for Archaeological Research (WMCAR) on September 28, 1993. This investigation was intended to provide specific information concerning the nature and distribution of potential archaeological resources within the project area (approximately 11,933 m2 [39,150 ft.2]). The work included a review of the existing archaeological sites and an evaluation of extant documentary and cartographic sources pertaining to the project area

    Life on the edge of Gloucester Town : evaluation and data recovery at sites 44GL171 and 44 GL177 associated with the Environmental Toxicology and Pathology Research Center, Virginia Institute of Marine Science, Gloucester County, Virginia

    The William and Mary Center for Archaeological Research (WMCAR) conducted archaeological data recovery on portions of Sites 44GL171 and 44GL177, which lie within the boundaries of the proposed Environmental Toxicology and Pathology Research Center (ETPRC) building on the Virginia Institute of Marine Science (VIMS) campus from April 24, 1995 to July 6, 1995. These sites are located within the Gloucester Point Archaeological District.Data recovery from Sites 44GL 171 and 44GL 177 provides a rare glimpse into a turbulent period in the history of Gloucester Point. The pictures of Gloucester Town that emerge from this research illustrate economic prosperity and decline during the first half of the eighteenth century, and short-term military occupation during the Revolutionary War. These events had profound effects on Gloucester Town\u27s residents and late eighteenth- and early nineteenth-century settlement in the town
