we report the case of a three-year-old girl who complained from dysphagia and post-prandial vomiting since she was 6months old. several diagnostic work-ups were performed for her problem. upper gi endoscopy was normal but barium swallow revealed an external pressure effect over upper part of the esophagus (figure 1) and the ct angiography of thoracic aorta showed that this external pressure eff...

The present study investigates the crystal preferred orientation (CPO) of quartz crystals in psammitic rocks to ascertain the deformationmechanism using electron backscatter diffraction (EBSD) on quartz crystals from north of the Renvyle-Bofin Slide (RBS) nearLetterfrack in western Ireland. Complete crystallographic orientations were determined for several thousand individual quartz crystalsin ...

This paper presents a two-stage low-noise ultra-wideband amplifier to obtain high and smooth gain in 180nm CMOS Technology. The proposed structure has two common source stages with inductive feedback. First stage is designed about 3GHz frequency and second stage is designed about 8GHz. In simulation, symmetric inductors of TSMC 0.18um CMOS technology in ADS software is used.Simulations results ...

In two studies the role of biomedical knowledge in the diagnosis of clinical cases was explored. Experiment 1 demonstrated a decrease in the use of biomedical knowledge with increasing expertise. This result appeared to be at variance with some findings reported in the literature (e.g., Lesgold. 1934). but supported those of others (e.g., Patel, Evans, & Groen, 1989). In Experiment 2, three pos...

This paper was prepared for publication after the death of the author by T. Lewis, M.Sc. Professor R. A. Milne, F.R.S., has also seen the manuscript and makes the following observation: “ This paper should be published not only as an act of piety in Schott’s memory, but because it is done with intense care and skill and is throughout critical. Quantum physicists of the type who write the fashio...

By custom in the last few decades, the President's address has usually been clinical, but loosely connected with medicine or science. He has had free choice of subject, by tradition the tide is not disclosed beforehand, and no Questions are asked afterwards. All this gives him considerable advantage, I have therefore chosen a subject which I think is of interest to many People, that of the pict...
