Spectroscopy of 46 P / Wirtanen during its 1997 apparition
Comet 46P/Wirtanen was observed during five observing runs around its perihelion passage from 1997 January 28 to June 02. The spectra acquired extend from 5200 to 10000 Å at spectral resolutions of 12 Å and 18Å. A total of 16 spectral averages, each comprising about 40 minutes of integration time, were obtained. The production rate of H2O near perihelion averaged 2.7 × 1028 molecules/sec. The c...

We propose a quantization of the Painlevé system of type A (1) l studied by M. Noumi and Y. Yamada [13]. This quantization has the affine Weyl group symmetry of type A (1) l (l ≥ 2) as well as the Lax representation. For even l, the quantized system of type A (1) l can be obtained as the continuous limit of the discrete system constructed from the affine Weyl group symmetry of type A (1) l+1 .

Study of which the social work survey forms a part is anticipated and in that we shall deal again with some of the points raised earlier and those raised by critics such as your correspondent. However, lest your readers should misapprehend our tentative arguments, may I outline them here? The context is one of shortage of professionally qualified mental health social workers, particularly in th...

In the paper, we consider the problem of computing visibility information on digital terrain models. Visibility problems on polyhedral terrains are classi ed according to the kind of visibility information computed into point visibility, line visibility and region visibility. A survey of the state-of-the-art of the algorithms for computing visibility is presented, according to the classi cation...

We regret to record the death of Dr. P. P. Johnson, of Yatton, .after a long and painful illness, borne with much fortitude. Dr. Johnson was 57 years of age, and was educated at Sedbergh, afterwards proceeding to Edinburgh University, where he took his degree in 1877. He practised for over nine years at Littleborough, in Lancashire, and for a short time in Starbotton, Yorkshire, and came to Yat...
