1. Structure in the early afterglow light curve of the gamma-ray burst of 29 March 2003.

    Nature 423(6942):843 (2003) PMID 12815423

    Gamma-ray bursts (GRBs) are energetic explosions that for 0.01-100 s are the brightest gamma-ray sources in the sky. Observations of the early evolution of afterglows are expected to provide clues about the nature of the bursts, but their rapid fading has hampered such studies; some recent rapid...

  3. Ultraviolet protection factors for clothing: an intercomparison of measurement systems.

    Photochemistry and Photobiology 77(1):58 (2003) PMID 12856884

    In recent years the need to standardize measurement protocols for quantifying the degree of ultraviolet radiation (UVR) protection provided by clothing has led to the introduction of a number of standards around the world. To date, these standards have specified spectral measurements of UVR tran...
