Boron abundances have been derived for seven main sequence B-type stars from HST STIS spectra around the B III 2066Å line. In two stars, boron appears to be undepleted with respect to the presumed initial abundance. In one star, boron is detectable but it is clearly depleted. In the other four stars, boron is undetectable implying depletions of 1 to 2 dex. Three of these four stars are nitrogen...

aim : to evaluate the diagnostic value of helicobacter pylori stool antigen test before and after eradication background : there are different methods for diagnosis and follow up of helicobacter pylori infection, including invasive methods done with endoscopy and non invasive ones such as ubt and urine analysis antibody. one of non invasive new methods is analysis of helicobacter pylori stool a...

Bravo® capsule (BC) (Medtronic, Minneapolis, MN) endoscopy is a reliable, viable, and well-tolerated diagnostic modality for resistant gastroesophageal reflux disease (GERD). Common complications of the procedure include early dislodgment, poor transmission, and premature removal due to intractable pain, while aspiration of the capsule is exceedingly rare. This paper reports a case of BC aspira...

[1] We analyze seismicity rate immediately before and after 82 main shocks with the magnitudes ranging from 3 to 5 using waveforms recorded by the Hi-net borehole array in Japan. By scrutinizing high-frequency signals, we detect 5 times as many aftershocks in the first 200 s as in the Japan Meteorological Agency catalogue. After correcting for the changing completeness level immediately after t...
