The NASA/IPAC Extragalactic I~atabase (INED) is an electronic research tool which provides uniquely powerful access to published multi-wavelength data on extragalactic objects. It consists of a computer database with a broad range of published information, and a user interface which allows fast and flexiblc~ retrieval of the information via the lntm-net. It is accessible anonymously and free of...

Multiple sustainable methodologies were developed for the chemical upgrading of HMF: i) at 30–90 °C, highly selective base-catalyzed acetylation and carboxymethylation reactions HMF with nontoxic reagents as isopropenyl acetate (iPAc) dimethyl carbonate (DMC) achieved to prepare corresponding ester products, (5-formylfuran-2-yl)methyl (5-formylfuran-2-yl) methyl carbonate, respectively; ii) bas...

Recent studies have found the earth's peculiar velocity to be significant in microwave background based tests for compact cosmic topology, and modifications to these tests have been proposed. Tests of non-gaussianity, weak lensing analysis and new tests using improved CMB data will also be sensitive to peculiar velocity. We propose here to simplify matters by showing how to construct a deaberra...

We consider the effect of optical depth of the 2 S level on the nebular recombination spectrum of He I for a spherically symmetric nebula with no systematic velocity gradients. These calculations, using many improvements in atomic data, can be used in place of the earlier calculations of Robbins. We give representative Case B line fluxes for UV, optical, and IR emission lines over a range of ph...

We will be presenting updated results to our optical survey of the "error boxes" of EGRET unidentified sources at high Galactic latitude. It is our intention to search for potential blazars that may have been missed in the original identification process. We have first searched the error boxes of unidentified sources at Ibl > 20° for flat spectrum radio sources using NASA Extragalactic Database...

The Dwingeloo Obscured Galaxies Survey (DOGS) is a 21-cm blind survey for galaxies hidden in the northern ‘Zone of Avoidance’ (ZOA): the portion of the optical extragalactic sky which is obscured by dust in the Milky Way. Like the Parkes southern hemisphere ZOA survey, the DOGS project is designed to reveal hidden dynamically important nearby galaxies and to help ‘fill in the blanks’ in the loc...

Bacterial type III secretion systems serve to translocate proteins into eukaryotic cells, requiring a secreton and a translocator for proteins to pass the bacterial and host membranes. We used the contact hemolytic activity of Shigella flexneri to investigate its putative translocator. Hemolysis was caused by formation of a 25-A pore within the red blood cell (RBC) membrane. Of the five protein...

We investigate the number of physical companion galaxies for a sample of relatively isolated elliptical galaxies. The NASA/IPAC Extragalactic Database (NED) has been used to reinvestigate the incidence of satellite galaxies for a sample of 34 elliptical galaxies, first investigated by Bothun & Sullivan (1977) using a visual inspection of Palomar Sky Survey prints out to a projected search radiu...
