Properties of the redshift
Central to any analysis of dynamical systems, or large scale motion, is the interpretation of redshifts of galaxies as classical Doppler velocity shifts. This is a testable assumption and for many years evidence has accumulated that is inconsistent with the assumption. Here, the authors review recent evidence suggesting systematic radial dependence and temporal variation of redshifts

A general maximum entropy principle for self-gravitating perfect fluid
We consider a self-gravitating system consisting of perfect fluid with
spherical symmetry. Using the general expression of entropy density, we
extremize the total entropy under the constraint that the total number of
particles is fixed. We show that extrema of coincides precisely with the
relativistic Tolman-Oppenheimer-Volkoff (TOV) equation of hydrostatic
equilibrium. Furthermore, we apply the maximum entropy principle to a charged
perfect fluid and derive the generalized TOV equation. Our work provides a
strong evidence for the fundamental relationship between general relativity and
ordinary thermodynamics.Comment: 13 pages, no figure. The arguments have been improved so that the
assumption p=p(\rho) is no longer neede
Upper Pennsylvanian Missourian Corals of Iowa
As in Kansas where distinct zonation of corals has been recognized, the dissepimental Rugosa Dibunophyllum, Neokoninckophyllum and Geyerophyllum are invariably associated with limestones and thin calcareous shale interbeds within limestone units. In both states, the nondissepimental rugose genera Lophamplexus and Stereostyllls have been collected from both limestones and thick intervening shale units. The tabulate genera Syringopora and Cladochonus are restricted to limestones in both areas. Although the vertical distribution of Iowa and Kansas dissepimental corals is similar, Iowa rocks contain fewer and generally smaller corals than correlative Kansas units. Elements of the informal dissepimental coral zones 1, 3 and 4 established by Cocke (1970, 1972) in Kansas are presently known in Iowa
