77 fun facts about Austria This post is part of a series of fun facts posts I’m doing for every country I have articles about here on the blog. Given their nature, these posts are research-based and even though a lot of time has gone into them, it’s still possible a mistake has ...
If you don't wish to use JavaScript, please visit our frame-based site Narrow space fluttering hunters Pteronotus parnellii is our narrow-space fluttering hunter and its echolocation strategy is to emit in the 60Khz range and use the doppler effect to detect objects which are moving. (Full ...
The Kremlin figures that Trump’s presidency gave them four years of breathing room and they probably see there’s a good possibility that their window of opportunity is about to close - prompting them to take action now, knowing they may find it far more difficult to do so unde...
These gravitational tugs create a Doppler effect, or change in the observed wavelength, in the starlight. In studying Proxima Centauri's so-called "Doppler wobble," astronomers using the European Southern Observatory telescopes in Chile discovered that the star had a planet slightly larger than ...
While there, Mendel studied mathematics and physics under Christian Doppler, after whom the Doppler effect of wave frequency is named; he studied botany under Franz Unger, who had begun using a microscope in his studies, and who was a proponent of a pre-Darwinian version of evolutionary theory...

The effect of preoperative chemo-radiotherapy is under scrutiny. The indications for a protective stoma remain debatable. Omentoplasty, bowel preparation, the use of a drain, and tumor stage do not seem to affect the leakage rate. The type of operation (open or laparoscopic) and anastomosis (...
Doppler shift When the source of a wave moves relative to an observer, the observer notices a change in the frequency of the wave. This change is called theDoppler effect, after its discoverer, Austrian physicistChristian Doppler. Consider a sourceemittinga wave such as light or sound of frequ...
