Tracheal deviation is a clinical sign that results from unequal intrathoracic pressure within the chest cavity. It is most commonly associated with traumatic pneumothorax, but can be caused by a number of both acute and chronic health issues, such as pneumonectomy, atelectasis, pleural effusion, fibrothorax (pleural fibrosis), or some cancers ...
In physics the Lamb shift, named after Willis Lamb, refers to an anomalous difference in energy between two electron orbitals in a hydrogen atom. The difference was not predicted by theory and it cannot be derived from the Dirac equation, which predicts identical energies. Hence the Lamb shift refers to a deviation from theory seen in the ...
1. 1. 1. The bitwise AND operator is a single ampersand: &. It is just a representation of AND which does its work on the bits of the operands rather than the truth value of the operands. Bitwise binary AND performs logical conjunction (shown in the table above) of the bits in each position of a number in its binary form.
If you see an image challenge question when sending mail, you should just be able to complete the challenge then send mail. If, however, you correctly answer the image challenge and still can't send mail, it could be a sign of a more serious issue with your account, which may require additional steps to secure your account.
A source of light waves moving to the right, relative to observers, with velocity 0.7 c. The frequency is higher for observers on the right, and lower for observers on the left. The relativistic Doppler effect is the change in frequency, wavelength and amplitude [1] of light, caused by the relative motion of the source and the observer (as in ...
Grimm's law (also known as the First Germanic Sound Shift) is a set of sound laws describing the Proto-Indo-European (PIE) stop consonants as they developed in Proto-Germanic in the first millennium BC, first discovered by Rasmus Rask but systematically put forward by Jacob Grimm. It establishes a set of regular correspondences between early ...
