Jaundice The medical term for it is "icterus", from the Greek word "ίκτερος"; adjectival form, icteric. Jaundice Jaundice, also known as icterus, is a yellowish or greenish pigmentation of the skin and whites of the eyes due to high bilirubin levels. It is commonly associated with itchiness. The feces may be pale and the urine dark. Jaundice in babies occurs in over half in the first week following birth and in most is not a problem. If bilirubin levels in babies are very high for too long, a type of brain damage, known as kernicterus, may occur. Causes of jaundice vary
Lorenz gauge condition J. Thomson's interpretation of data for electrons (after which investigation into electrical phenomena changed from time-dependent electric charge and electric current distributions over to moving point charges). Lorenz gauge condition In electromagnetism, the Lorenz gauge condition or Lorenz gauge (sometimes mistakenly called the Lorentz gauge) is a partial gauge fixing of the electromagnetic vector potential. The condition is that formula_1 This does not completely determine the gauge: one can still make a gauge transformation formula_2 where formula_3 is a harmonic scalar function (that is, a scalar function satisfying formula_4 the equation of a massless scalar field). The Lorenz condition is
