Island work center

Acknowledgements We express our sincere gratitude to University of Rhode Island Transportation Center and Honda Motors for their financial support for this work. We would like to thank Paul Johnson, Evan Wujick, for their support throughout the work. 

In an educational laboratory such overhead mounting must be planned with care. The typical work benches here are either peninsulas or islands where the utility box would go down the center with a shelf on top. The total height must be such that the instructor is able to look over the shelf in order to supervise a class. To complicate matters, there may be a waste water trough along the center of the bench which requires some free space above it. These multiple requirements present a challenge to the designer. 

Drain troughs are often put along the center of the island or peninsula type work benches, sometimes with water outlets... 

Electrical outlets can be installed in one of several ways. Small pedestals holding two or more outlets are often placed along the rear of wall-mounted work benches. They may also be put along the center of peninsulas or islands. Wiring is from below the countertop, which makes modifications difficult, just as with plumbing. While easy to reach, pedestals clutter the top and interfere with cleaning. 

This work is currently supported by NSF grant DMR 9313371 and by the Materials Science Center at Cornell University under NSF Grant DMR 9121654. We are particularly grateful to the staff of the Cornell Nanofabrication Facility for their assistance in creating the periodic starting stractures. The LEEM experiments on Si were carried out in collaboration with Ruud Tromp and Marion Mankos at IBM, Yorktown Heights, NY. Norm Bartelt of Sandia Labs, Livermore, CA has modeled the kinetics of the island and hole decay on the 2-D gratings. 

The main objective of the present work is to study the provenance of majolica pottery found on important Gran Canaria Island archaeological sites that have been subject of archaeological research. Furthermore, by means of archaeometric characterization, the role played by the majolica produced in Seville that was documented historically as an import into the Canary Islands, is also assessed. Majolica from different production centers also is considered, thereby adding a complexity factor to the Canary trade relationships panorama in a historical period when, in theory, a very tight control existed over trade with the Americas. 

The present study suggests the arrival of ceramics and possibly other goods, from different places around the Mediterranean, such as Italy, Manises, Barcelona, Portugal, and possibly Holland. The extent of the participation of all these different productions centers, and their impact and the variety of products involved in this process remains to be determined. However, this study shows that the trade netwoik, the most important one at that time, was far more complex than previously assumed. The exact mechanisms by which the different pottery enters these flows, whether it is licit or illicit, is not easily understood, but the work must be extended in order to obtain a more comprehensive picture. The Canary Island s role in this network becomes, then, a central subject of research.
