The Parkes 2700 Mhz Survey: Counts of the Sources and their Distribution on the Sky| > 10°. Eleven parts of the catalogue have been published as Astrophysical Supplements of the Aust. J. Phys. (Numbers 19, 21, 26, 30, 32, 34, and 39); part 11 and subsequent parts consist of re-surveys of some areas to fainter flux density limits. The current version of the composite catalogue for

The Statistical Analysis of Anisotropiesether they are bunched into clusters or lie in preferred regions of space. There are many methods of testing for clustering in point processes and since they are not all equally good this contribution is presented as a brief guide to what seem to be the best of them. The radio sources certainly do n

Spectra of Southern Radio Sources the galactic plane the whole sky south of +25° has been surveyed to a flux density limit of 0.6 Jy at 2700 MHz and within this area surveys to limits of 0.35, 0.25 or 0.1 Jy have been made covering 3.5 sr. Flux densities have been measured at 5000 MHz for all sources stronger than 0.35 Jy at 2700 M

The Flux Density-Angular Size Distribution for Extragalactic Radio Sourceshave been determined for a new sample of 119 sources observed during 1973–74, and agree well with the value of about 10 arc sec determined earlier by Swarup (1975). For 8 different flux density ranges, the angular size distribution for the All-sky, 3CR and Ooty radio sources have been compared with

James N. Douglas,Frank N. Bashted to disulfates which selectively react on benzene and thus appear to be the sites of higher acidity. This high acidity can indeed be induced on zirconia by contact with a solution of ammonium persulfate and calcination at moderate temperature. The proposal that acid sites are linked to defects of
