We discuss results from sensitive, wide-field imaging of the millimeter extragalactic background using the Max-Planck Millimeter Bolometer array (MAMBO) at the IRAM 30 m telescope. The detection of a far-infrared and sub-millimeter wavelength background by COBE, and the first sensitive, high-resolution SCUBA images of the sub-mm background have caused significant revisions of our picture of the...

Recent investigations of how the median size of extragalactic radio sources change with redshift have produced inconsistent results. Eales (1985) compared the radio and optical properties of a bright 3C and faint 6C sample and concluded that for a universe with 0 = 0 Dmed / (1 + z) 1:1 , with Dmed being the median size of the radio sources at a given epoch and z the redshift. Oort, Katgert, and...

Parapodial extensions of the foot are particularly well developed in Aplysia fasciata, in which species they function during swimming. As was indicated in earlier studies (Hughes & Tauc, 1962), many of the nerves which innervate the foot sensu stricto of other species supply the parapodia of Aplysia fasciata. In fact there is no detailed account of the branching of the nerves in A. fasciata; Ma...

PURPOSE Proliferative Diabetic Retinopathy (PDR) and Eales' Disease (ED) have different aetiologies although they share certain common clinical symptoms including pre-retinal neovascularization. Since there is a need to understand if the shared end-stage angiogenic pathology of PDR and ED is driven by common stimulating factors, we have studied the cytokines contained in vitreous from both pati...
