Bevan Sharpless
Bevan Percival Sharpless (August 2, 1904 – October 28, 1950) was an American astronomer, best known for his 1944 discovery that the orbit of Phobos was decaying. Early life Sharpless was born to Ethel Mae Bevan and Albert Wayne Sharpless on August 2, 1904, in Chester Heights, Pennsylvania, the only child of the marriage. He attended Swarthmore High School then Swarthmore College, graduating in 1926 with an A.B. degree in mathematics.

Stewart Sharpless
Stewart Sharpless (March 29, 1926 – January 19, 2013) was an American astronomer who carried out fundamental work on the structure of the Milky Way galaxy. As a graduate student at Yerkes Observatory he worked under William Morgan with fellow graduate student Don Osterbrock. He helped Harold Johnson and Morgan with calculations used to help define the UBV photometric system. In 1952, Sharpless and Osterbrock published their observations that demonstrated the spiral structure of the Milky Way by estimating the distances to H II regions and young hot stars. For a while Sharpless was at Mount Wilson Observatory where he worked on galaxy photography with Walter Baade and Edwin Hubble. In 1953 Sharpless joined the staff of the United States Naval Observatory Flagstaff Station. Here he surveyed and cataloged H II regions of the Milky Way Galaxy using the images from the Palomar Sky Survey. From this work Sharpless published his catalog of H II regions in two editions, the first i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sharpless Catalog
The Sharpless catalog is a list of 313 H II regions (emission nebulae) intended to be comprehensive north of declination −27°. (It does include some nebulae south of that declination as well.) The first edition was published in 1953 with 142 objects (Sh1), and the second and final version was published by US astronomer Stewart Sharpless in 1959 with 312 objects. Sharpless also includes some planetary nebulae and supernova remnants, in addition to H II regions. In 1953 Stewart Sharpless joined the staff of the United States Naval Observatory Flagstaff Station, where he surveyed and cataloged H II regions of the Milky Way using the images from the Palomar Sky Survey. From this work Sharpless published his catalog of H II regions in two editions: the first in 1953, with 142 nebula; and the second and final edition in 1959, with 312 nebulae.Stewart SharplessA Catalogue of H II Regions ''Astrophysical Journal'' Supplement, vol. 4, p.257, 1959 Sharpless coordina ...

Disappearance Of Toni Sharpless
In the predawn hours of August 23, 2009, Toni Sharpless (born December 27, 1979)Missing person flyer reproduced at and her friend Crystal Johns left a party at the home of Philadelphia 76er Willie Green in Penn Valley, Pennsylvania, United States. Not long after leaving, Johns suggested to Sharpless, whose erratic and combative behavior had led Green to ask that they leave, that she was not sober enough to drive; in response, Sharpless pulled over and told Johns to get out, which she did. Sharpless has not been seen since then. An early theory, that she might have accidentally driven her car into the nearby Schuylkill River, was discarded when searches of the river were fruitless. An apparent break in the case came two weeks later when an automatic license plate reader recorded her 2002 Pontiac Grand Prix's plates among parked vehicles in Camden, New Jersey, across the Delaware River from Philadelphia. There had been other reported sightings of Sharpless in Camden, but police ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Madama Butterfly
''Madama Butterfly'' (; ''Madame Butterfly'') is an opera in three acts (originally two) by Giacomo Puccini, with an Italian libretto by Luigi Illica and Giuseppe Giacosa. It is based on the short story " Madame Butterfly" (1898) by John Luther Long, which in turn was based on stories told to Long by his sister Jennie Correll and on the semi-autobiographical 1887 French novel '' Madame Chrysanthème'' by Pierre Loti.Chadwick Jenna"The Original Story: John Luther Long and David Belasco" on columbia.edu Long's version was dramatized by David Belasco as the one-act play '' Madame Butterfly: A Tragedy of Japan'', which, after premiering in New York in 1900, moved to London, where Puccini saw it in the summer of that year. The original version of the opera, in two acts, had its premiere on 17 February 1904 at La Scala in Milan. It was poorly received, despite having such notable singers as soprano Rosina Storchio, tenor Giovanni Zenatello and baritone Giuseppe De Luca in l ...

Sharpless Asymmetric Dihydroxylation
Sharpless asymmetric dihydroxylation (also called the Sharpless bishydroxylation) is the chemical reaction of an alkene with osmium tetroxide in the presence of a chiral quinine ligand to form a vicinal diol. The reaction has been applied to alkenes of virtually every substitution, often high enantioselectivities are realized, with the chiral outcome controlled by the choice of dihydroquinidine (DHQD) vs dihydroquinine (DHQ) as the ligand. Asymmetric dihydroxylation reactions are also highly site selective, providing products derived from reaction of the most electron-rich double bond in the substrate. It is common practice to perform this reaction using a catalytic amount of osmium tetroxide, which after reaction is regenerated with reoxidants such as potassium ferricyanide or ''N''-methylmorpholine ''N''-oxide. This dramatically reduces the amount of the highly toxic and very expensive osmium tetroxide needed. These four reagents are commercially available premixed (" AD ...
