A study of the angular size-redshift relation for models in which Λ decays as the energy density Abstract. By modifying the Chen and Wu ansatz, we have investigated some Friedmann models in which Λ varies as ρ. In order to test the consistency of the models with observations, we study the angular size-red-shift relation for 256 ultracompact radio sources selected by Jackson and Dodgson. The ang...

The present work was carried out as part of a programme ofresearch on the inactivation of L-adrenalne (I) in the body. There are two views ofthe mode ofinactivation ofadrenaline: briefly, the first is that the inactivation inv'olves monoamine oxidase which oxidatively deaminates adrenaline, and the second is that the inactivation takes place through conjugation of the hydroxyl groups of adrenal...

Soc., 74, 3199, 1952. 9 In addition to the fractions shown in Table 1, a substance having an apparent glucuronic acid-hexosamine ratio of 0.62 by the carbazole method was isolated in the amount of 0.15 per cent of the wet weight from the spleen of case K. N. The nature of the hexosamine in this fraction wa...

Some years ago (Jackson and Dodgson 1997) analysis of the angular-size/redshift relationship for ultra-compact radio sources indicted that for spatially flat universes the best choice of cosmological parameters was Ωm = 0.2 and ΩΛ = 0.8. Here I present an astrophysical model of these sources, based upon the idea that for those with redshift z > 0.5 each measured angular size corresponds to a si...

Collective decision making problems can be seen as finding an outcome that is “closest” to a concept of “consensus”. Nitzan (1981) introduced “Closeness to Unanimity Procedure” as a first example to this approach and showed that the Borda rule is the closest to unanimity under swap distance (a.k.a the Kemeny (1959) distance). Meskanen and Nurmi (2008) shows that the Dodgson rule is the closest ...
