    No full text
    Artist's depiction of the Monitor and Merrimac, Hampton Roads, Virginia, circa 1951-1980. Painting of the battle between the Monitor and the Merrimac warships. Caption reads: "Monitor and Merrimac, first battle of ironclad warships, Hampton Roads, Virginia - The Merrimac's mission was to destroy the Union fleet and to starve Fort Monroe into surrender. The Confederate ironclad sank two powerful wooden frigates near Newport News, drove another aground, and chased two others back to Fort Monroe. The Union Monitor did not arrive until after dark. Next day, March 9, 1862, the two ironclads fought a savage battle which lasted four hours and ended in a draw." Postcard number: 64232A

Bankhead Magruder notifying him of the re-enforcement of Fort Monroe and Newport News by the Federal Army and the belief the fedral army and navy will attempt to get to Richmond by the James River. Possibilities of the uses of the U.S.S. Monitor and C.S.S. Virginia in this endeavor are described

    Artist's depiction of Fortress Monroe and Old Point Comfort, Virginia, as it was in 1861, circa 1930-1945. Caption reads: "This fortification was originally constructed in 1609, and was then known as Fort Algernoune. The construction of Fortress Monroe was begun in 1819 and finished in 1830. The battle between the Monitor and the Merrimac on March 9, 1862, the first conflict between iron clad vessels, was fought in Hampton Roads, in sight of this fortress." Postcard number: 55371

    SPATIAL REGRESSION MODELS FOR YIELD MONITOR DATA: A CASE STUDY FROM ARGENTINA

    No full text
    Precision agricultural technology promises to move crop production closer to a manufacturing paradigm, but analysis of yield monitor, sensor and other spatial data has proven difficult because correlation among neighboring observations often violates the assumptions of classical statistical analysis. When spatial structure is ignored variance estimates tend to be inflated and significance levels of test statistics are reduced. The gap between data analysis and site-specific recommendations has been identified as one of the key constraints on widespread adoption of precision agriculture technology. This paper compares four approaches that explicitly incorporate spatial correlation into regression models: (1) a spatial econometric approach; (2) a polynomial trend regression approach; (3) a classical nearest neighbor analysis; and (4) and a geostatistic approach. In the Argentine data studied, the spatial econometric, geostatistical approach and spatial trend analysis offered stronger statistical evidence of spatial heterogeniety of nitrogen response than the ordinary least squares or nearest neighbor analysis. All the spatial models led to the same economic conclusion, which is that variable rate nitrogen is potentially profitable. The spatial econometric analysis can be implemented on relatively small data sets that do not have enough observations for estimation of the semivariogram required by geostatistics. The spatial trend analysis can be implemented with ordinary least squares functions that are already available in some GIS software. In this study, the main benefit of using spatial regression analysis is increased confidence in the corn yield response estimates by management zone, and conclusions about the profitability of precision agriculture technologies.Crop Production/Industries,

    The use of two novel techniques in the coagulopathic trauma patient in intensive care

    No full text
    Severe Trauma is a multisystem disorder with a high mortality in an often young population. It offers a big challenge to the intensivist, and any help that is available might prove decisive in saving the patient’s life. This case report highlights the use of two novel technologies in critically ill trauma patients, namely the use of activated recombinant factor VII (Novoseven®) to correct coagulopathy, and the use of a central venous oxygen saturation monitor (PresepTM with VigileoTM) to optimise perfusion.peer-reviewe

    The Florida Keys Mosquito Control District utilises dry ice-baited light traps to monitor mosquito populations on Key Largo, Florida. This paper describes the methodology of trapping, habitat description and dataset of adult mosquito populations from 18 years of weekly monitoring from a single site on Key Largo, Monroe County, Florida, USA.This paper details a previously unreported dataset derived from trap collections made on Key Largo, Florida at a site designated as "Gun Club Road.

    A Workplace Air Monitor for Uranium Particulate Detection

    No full text
    An air monitor has been developed at the Oak Ridge Y-12 Plant to sample the air in enriched uranium processing areas and to detect elevated particulate concentrations due to an upset condition. The monitor measures the alpha particle activity from material collected on 47-mm filter paper. Three energy windows are used to allow quantification of background activity from radon and thoron daughters and correction of their spillage into the uranium window. There is sufficient monitor memory to hold a history file of six days\u27 activity from three sampling heads at 20-min status intervals. Alarm signals are activated if the absolute level of activity on a filter exceeds a predefined level, or if an excessively fast rate of buildup is occurring, which would cause the absolute level to be exceeded. This monitor was combined with an absolute particle counter and data were collected at a processing station where uranium dust is known to be present. The occurrence of high particle count activity in the 3.0–10.0-µ range was followed by increased alpha activity on the filter paper. This strong correlation has not been reported

    The Florida Keys Mosquito Control District has used dry ice-baited light traps to monitor mosquito populations on Key Largo since 2003. This paper describes the methodology of trapping, the habitat and the dataset of adult mosquito populations from 18 years of weekly monitoring from a single site on Key Largo, Monroe County, FL, USA.This data paper provides previously unpublished data from a single trapping location in Key Largo, Florida. Two new species have been added to previously-published data from this trapping site
