Xanthochromia, from the Greek xanthos (ξανθός) "yellow" and chroma (χρώμα) "colour", is the yellowish appearance of cerebrospinal fluid that occurs several hours after bleeding into the subarachnoid space caused by certain medical conditions, most commonly subarachnoid hemorrhage. [1]

A branch of physics that studies atoms as isolated systems of electrons and an atomic nucleus. Compare nuclear physics. atomic structure atomic weight (A) The sum total of protons (or electrons) and neutrons within an atom. audio frequency A periodic vibration whose frequency is in the band audible to the average human, the human hearing range.
In the magnitude image, cerebrospinal fluid (CSF) that is flowing is a brighter signal and stationary tissues are suppressed and visualized as black background. The phase image is phase-shift encoded, where white high signals represent forward flowing CSF and black low signals represent backwards flow.
Caesium fluoride has the halite structure, which means that the Cs + and F − pack in a cubic closest packed array as do Na + and Cl − in sodium chloride. [3] Unlike sodium chloride, caesium fluoride's anion is smaller than its cation, so it is the anion size that sterically inhibits larger coordination numbers than six under normally ...
In quantum chemistry, a configuration state function (CSF), is a symmetry-adapted linear combination of Slater determinants. A CSF must not be confused with a configuration . In general, one configuration gives rise to several CSFs; all have the same total quantum numbers for spin and spatial parts but differ in their intermediate couplings.
Traumatic CSF rhinorrhoea is the most common type of CSF rhinorrhoea. [1] It may be due to severe head injury, or from complications from neurosurgery. [1] Spontaneous CSF rhinorrhoea is the most common acquired defect in the skull base bones (anterior cranial fossa) causing spontaneous nasal liquorrhea.
