The Westward Expansion of Domestic Queensware: The Red Rose Transit Site, Lancaster, Pennsylvania.

Archaeological excavations undertaken by URS/AECOM at the Red Rose Transit Site from 2008 through 2010 revealed late 18th and early 19th century A horizon/yard deposits, a stone-lined well, a redware kiln and evidence of brass manufacturing in the south half of Lot 104. These deposits and features located beneath 19th century train shed tracks at the corner of Chestnut and Queen Streets produced a small quantity of domestic queensware. Lancaster was the gateway to the west in the 18th and early 19th century for the shipment of goods. The existence of domestic queensware at the Red Rose Transit site indicates the ware was available and in use by consumers in Lancaster. This inland city likely played an important role in the ware’s distribution further west

Subsonic Boundary-Layer Wavefront Spectra for a Range of Reynolds Numbers

Aero-optic measurements of turbulent boundary layers were performed in wind tunnels at the University of Notre Dame and California Institute of Technology for heated walls at a range of Reynolds numbers. Temporally resolved measurements of wavefronts were collected at a range of Mach numbers between 0.03 and 0.4 and the range of Re_θ between 1,700 and 20,000. Wavefront spectra for both heated and un-heated walls were extracted and compared to demonstrate that wall heating does not noticeably alter the shape of wavefront spectra in the boundary layer. The effect of Reynolds number on the normalized spectra was also presented, and an empirical spectral model was modified to account for Reynolds number dependence. Measurements of OPD_(rms) for heated walls were shown to be consistent with results from prior experiments, and a method of estimating OPD_(rms) and other boundary layer statistics from wavefront measurements of heated-wall boundary layers was demonstrated and discussed

“A Bright Pattern of Domestic Virtue and Economy”: Philadelphia Queensware at the Smith-Maskell Site (28CA124), Camden, New Jersey

Excavations at the Smith-Maskell Site (28CA124) in the Spring of 2011 by URS Corporation revealed a number of early 19th-century features behind what was once 318 Cooper Street in Camden, New Jersey. These features produced significant quantities of Federal period tea and tablewares, including a number of Philadelphia Queensware vessels. During this period Camden was beginning its transition from a scattering of sparsely populated villages to a city of summer residences and country retreats for Philadelphia’s well-to-do middle class. The likely owners of the Philadelphia Queensware found at the Smith-Maskell Site were among this prosperous middle class, and thus the presence of this ware in their household assemblages insinuates that consumer choice, particularly related to patriotism and the desire to support domestic industries, played an important factor in the ware’s apparent popularity and widespread distribution. While trade embargos in place before and after the War of 1812 certainly affected the availability of English ceramics, the Philadelphia Queensware found at the Smith-Maskell site speaks to other forces at work as well

An electromagnetic induction method for underground target detection and characterization

An improved capability for subsurface structure detection is needed to support military and nonproliferation requirements for inspection and for surveillance of activities of threatening nations. As part of the DOE/NN-20 program to apply geophysical methods to detect and characterize underground facilities, Sandia National Laboratories (SNL) initiated an electromagnetic induction (EMI) project to evaluate low frequency electromagnetic (EM) techniques for subsurface structure detection. Low frequency, in this case, extended from kilohertz to hundreds of kilohertz. An EMI survey procedure had already been developed for borehole imaging of coal seams and had successfully been applied in a surface mode to detect a drug smuggling tunnel. The SNL project has focused on building upon the success of that procedure and applying it to surface and low altitude airborne platforms. Part of SNL`s work has focused on improving that technology through improved hardware and data processing. The improved hardware development has been performed utilizing Laboratory Directed Research and Development (LDRD) funding. In addition, SNL`s effort focused on: (1) improvements in modeling of the basic geophysics of the illuminating electromagnetic field and its coupling to the underground target (partially funded using LDRD funds) and (2) development of techniques for phase-based and multi-frequency processing and spatial processing to support subsurface target detection and characterization. The products of this project are: (1) an evaluation of an improved EM gradiometer, (2) an improved gradiometer concept for possible future development, (3) an improved modeling capability, (4) demonstration of an EM wave migration method for target recognition, and a demonstration that the technology is capable of detecting targets to depths exceeding 25 meters

The Angular Two-Point Correlation Function for the FIRST Radio Survey

The FIRST (Faint Images of the Radio Sky at Twenty Centimeters) survey now covers 1550 square degrees of sky where $07^{h}16 < \alpha < 17^{h}40$ and $28^{\circ}.3 < \delta < 42^{\circ}$. This yields a catalog of 138,665 sources above the survey threshold of 1 mJy, about one third of which are in double-lobed and multi-component sources. We have used these data to obtain the first high-significance measurement of the two-point angular correlation for a deep radio sample. We find that the correlation function between $0.02^{\circ}$ and $2^{\circ}$ is well fitted by a power law of the form $A\theta^{\gamma}$ where $A\approx 3\times 10^{-3}$ and $\gamma\approx -1.1$. On small scales ($\theta<0.2^{\circ}$), double and multi-component sources are shown to have a larger clustering amplitude than that of the whole sample. Sources with flux densities below 2 mJy are found to have a shallower slope than that obtained for the whole sample, consistent with there being a significant contribution from starbursting galaxies at these faint fluxes. The cross-correlation of radio sources and Abell clusters is determined. A preliminary approach to inferring spatial information is outlined.Comment: 22 pages, latex, 4 figures.

Domestic Queensware in Kensington-Fishtown: Excavating Philadelphia\u27s Waterfront Neighborhoods

Ongoing archaeological excavation undertaken by URS/AECOM along the I-95 corridor in Kensington-Fishtown in Philadelphia have brought to light 18th and 19th century domestic and industrial life along a three-mile section of the Delaware River waterfront. Excavation has revealed over 400 shaft features, yard deposits, and industrial foundations yielding over one million artifacts from a three mile section of the Delaware River waterfront. A small quantity of domestic queensware has been recovered from barrel and wood-lined box privies and from an early 19th century drain feature. The recovery of domestic queensware in Kensington-Fishtown has revealed that this ware had become part of the domestic fabric of early 19th century consumers in this part of the city

The Rise and Fall of American Queensware 1807-1822

. This article examines the history of several manufacturers of American queensware in Philadelphia, Pennsylvania, and beyond. Our research reveals that efforts to produce queensware were more extensive and widespread than previously thought. This survey expanded as we discovered references to contemporary queensware potteries in other parts of the United States during the first two decades of the 19th century. In all, 14 queensware-manufacturing ventures are identified and described from Pennsylvania, New Jersey, Ohio, what is now West Virginia, Vermont, and New Hampshire. Much of this research is drawn from period newspaper notices, advertisements, and surviving personal correspondence. The period sources provide a view of the experimental nature of this industry, document the search for raw materials, and describe various aspects of the manufacturing process
