| Sulfur mustard (HD) is a vesicating agent that alkylates cellular DNA and produces DNA strand breaks. The comet assay (single-cell gel electrophoresis) was used to detect HD-induced DNA single strand breaks in human peripheral blood lymphocytes (PBL). Specific steps taken to perform the comet assay in our laboratory are outlined. Briefly, PBL were mixed with agarose, mounted on a microscope slide, and lysed. The cellular DNA was treated with an ... |

The observations were made by the Chinese imperial astronomers from 12 December 146 B.C. to 3 February 1761 A. D. and preserved in the Chinese dynastic histories. Sixty-six of the records were of occultations, 83 records were of appulses, and 24 records were questionable ... |

|
| The interplay of collisional and collisionless phenomena in the interaction of a magnetoplasma streaming through neutral gas produces some of the most fascinating plasma physics phenomena. A key notion controlling such interactions is the existence of a critical velocity (U sub c) effect postulated in an ad hoc fashion by Alfven, in his model of the formation of the solar system. According to Alfven's postulate, whenever the relative velocity between ... |

| This report deals with a number of interrelated topics. The common thread is Laplace's method of initial orbit determination based on passively acquired optical data. We discuss this method's principal competitor (that of Gauss), the difficulties of Gauss's technique, and the traditional reasons the Gaussian method is preferred to the Laplacian. We reject this hegemony for a variety of reasons and concentrate on Laplace's method in an era of a ... |

The yield of cometary radicals such as CN, OH, etc. can be determined as a function of photolyzing wavelength. Quantum state distributions of the internal energy of the cometary radicals can also be measured as a function of wavelength permitting one to define the recoil velocity of the fragments. This type of information supplies the data needed ... |
