Francisco Goya painted few canvases during the last four years of his life spent in France. Several of his late masterpieces have fallen under scrutiny over the past ten years, their authenticity questioned by internationally respected scholars. Goya’s Head of a Monk can be counted among this group of disputed canvases. However, a comparison of the Monk with the artist’s sketchbooks, miniatures and murals created during his time in France as well as his last few years in Madrid indicate that this image as well as its underpainting were created by the master himself toward the end of his career.

A highly regio- and stereoselective oxime palladacycle/imidazolinium-catalyzed head to head dimerization of terminal aryl alkynes in water is presented. The reaction, which is carried out at 130 °C under microwave irradiation in the presence of 1,3-bis-(2,6-diisopropylphenyl)imidazolinium chloride as ligand, triethylamine as base, and TBAB as surfactant, allows the synthesis of (E)-1,4-enynes as single stereoisomers in good isolated yields.

This layer is a digital raster graphic of the historic 15-minute USGS topographic map of the Gay Head, Massachusetts quadrangle. The survey date (ground condition) of the original paper map is 1887, the edition date is September, 1893 and it was reprinted in 1905. A digital raster graphic (DRG) is a scanned image of a U.S. Geological Survey (USGS) standard series topographic map, including all map collar information. The image inside the map neatline is geo-referenced to the surface of the earth and fit to the Universal Transverse Mercator projection. The horizontal positional accuracy and datum of the DRG matches the accuracy and datum of the source map. The names of quadrangles which border this one appear on the map collar in their respective positions (N,S,E,W) in relation to this map.
