The LOFAR Two-metre Sky Survey (LoTSS) is a deep 120-168 MHz imaging survey that will eventually cover the entire Northern sky. Each of the 3170 pointings will be observed for 8 hrs, which, at most declinations, is sufficient to produce ~5arcsec reso

Polymeric Oxygen and Nitrogen: Why Not?

Autor: D. J. Mckay, J. S. Wright

Publikováno v: Science Progress. 82:151-170

Carbon occurs in many different polymeric forms, but nitrogen and oxygen do not. Beginning with the hydrogen polyoxides of general formula H2On, we look into the reasons for this observation. Calculations show that the geometry of an oxygen chain is

On 27 July 1994 the Burst and Transient Source Experiment (BATSE) on the Compton Gamma Ray Observatory detected an outburst of high energy X-rays from a previously unknown source in the constellation Scorpius. This source was designated GRO J1655-40.

The recent discovery of radio components apparently moving away from a Galactic source of transient X-ray emission faster than the speed of light (superluminal motion) has identified a low-energy Galactic counterpart to quasars. Here we report high-r

Cloning and characterization of human guanine deaminase. Purification and partial amino acid sequence of the mouse protein

Autor: G, Yuan, J C, Bin, D J, McKay, F F, Snyder

Publikováno v: The Journal of biological chemistry. 274(12)

Mouse erythrocyte guanine deaminase has been purified to homogeneity. The native enzyme was dimeric, being comprised of two identical subunits of approximately 50,000 Da. The protein sequence was obtained from five cyanogen bromide cleavage products
