Abstract We search for escaping helium from the hot super-Earth 55 Cnc e by taking high-resolution spectra of 1083 nm line during two transits using Keck/NIRSPEC. detect no absorption down to a 90% upper limit 250 ppm in excess or 0.27 mÅ equivalent width. This corresponds mass-loss rate less than ?10 9 g s ?1 assuming Parker wind model with plausible exosphere temperature 5000–6000 K, although...

In January of that year George D Lundberg, Editor of the Journal of the American Medical Association [JAMA], was sacked by the American Medical Association (Anderson 1999). Some five months later, Jerome P Kassirer, Editor of the New England Journal of Medicine, left the Journal when his contract with the Massachusetts Medical Society, the journal’s owners, was not renewed (Smith 1999). At the ...

The rainfall and runoff relationship becomes an intriguing issue as urbanization continues to evolve worldwide. In this paper, we developed a simulation model based on the soil conservation service curve number (SCS-CN) method to analyze the rainfall-runoff relationship in Guangzhou, a rapid growing metropolitan area in southern China. The SCS-CN method was initially developed by the Natural Re...
